Saturday, December 25, 1997

The sun shone through the treehouse window on a bright and mild Christmas Day, just after noon. Matt was laying on top of his cousin, Ellie. Both the teenage shore horses were as naked as the day they were born.

Matt's head and upper body rose slowly, then descended, again and again. Ellie could feel the hot breath of her cousin - her half-brother really, since their fathers were identical twins - as he lowered his face next to hers.

"Anything?" she said to him, their cheeks touching.

"I'm never gonna get it," he answered.

Despite trying everything, Matt was still unable to see the 3D images in the Magic Eye book laid out in front of them on the wooden planks of the treehouse floor.

"Probably not. But you get everything else," Ellie said. On a whim she stuck her long equine tongue out the side of her mouth, licking Matt's black horse lips.

"Ellie slobber on my face. Just what I wanted for Christmas..." Matt said sarcastically to his cousin.

"You like it..." she teased back, knowing it was true. She licked his nose, then wormed her tongue between his lips and into his mouth.

In an attempt to one-up her, Matt closed his lips around his cousin's tongue, sucking on it like a straw. This, however, only caused Ellie to stick her tongue out further into Matt's mouth. After a few seconds their tongue-play devolved into the pair making out, kissing ravenously.

Ellie was still in her 'super-horny' time of the month; this was what she knew it as, oblivious to the true nature of her condition. She was in heat.

Matt had fucked her just a few minutes ago, but when she was in heat her body was insatiable. Even as his cum was still dripping from her pussy she started wiggling her hips and pushing up against the colt lying on top of her. She loved the way it felt, his body covering hers at every point. Matt was almost exactly her same size but with different proportions. And with the key difference of possessing a massive horse-cock, of course.

"Mmmm," she half-moaned, half-whispered, breaking the kiss, "let's do it again..."

Matt grinned, but shook his head slightly. They'd fucked once, then he'd finished braiding her tail. Then they fucked again almost immediately. The cum from the first time was like lube, and it had been extraordinarily messy even _before_he finished inside her the second time. But now his balls were fully drained, and he wouldn't be able to do it again even if he wanted to. It would take at least an hour for him to recover enough for a round three.

"I don't think I can yet..." was Matt's response. He lifted himself up off Ellie a bit, his semi-flacid horse-cock peeking out of his leathery black sheath, resting idly on the small of Ellie's back. She turned her head to look at it, disappointed.

"Boo..." she sighed in protest.

"'Boo' yourself. I'm not a machine," Matt answered. "Besides, we don't have time."

Ellie's eyes widened. She had completely lost track of time. Bob was always extremely organized and punctual, so she knew that if he said the big Christmas meal would be ready at noon, it would be ready precisely at noon, whether they were back from their treehouse tryst or not.

"Oh crap! What time is it?"

"I dunno. Close to lunch time, probably," Matt said nonchalantly.

Without warning, Ellie pushed herself up off her belly and pulled her legs under her in quick, clean movement. Matt was flung off her back onto the wooden floor, landing awkwardly with a thud. His lack of dexterity stood in utter contrast to his cousin's athleticism.

"Oww! Hey! What gives?" Matt said as Ellie dashed for the pile of clothes in the corner. His cum was pouring from her pussy as she got up and darted across the room, leaving a nearly unbroken trail.

"If we're late for lunch we're gonna have to explain why, right? You wanna tell them?" Ellie said as she grabbed Matt's hoodie, which she pressed to her crotch before rubbing it all over her body like a towel after a shower.

"Yeah... guess not. Good point." Matt conceded.

"So get dressed. Come on, hurry!" she said, since Matt was still laying on the floor unfazed.

"All right, all right, I'm going," Matt said.

He got up slowly. He wasn't nearly as cum-covered as his cousin, but he still had a good amount on him and needed to 'towel off' just like Ellie had. Ellie was putting on her panties by the time he was on his hooves.

"Can you toss me the hoodie?" He asked, and Ellie tossed it to him. Matt dropped it. By the time he picked it up and started drying himself off, Ellie already had her jeans on.

"Don't wear that back," Ellie said.

Matt paused a moment, then held the hoodie up. It was an absolute mess, dripping in some places and glazed in others, while parts were crusty and gross from yesterday's dried cum.

"Think they'll notice? You can barely tell! Maybe I can spill some gravy on it at lunch, no one the wiser..." Matt said with a grin, holding it up as if he were displaying a tailored suit.

The edges of Ellie's mouth turned upwards as she tried to stifle a laugh.

"Quit making me laugh! Get dressed!" she said, beaming, as she threw Matt's clothes at him. He made her laugh again, though unintentionally, when he struggled to get his pants on for a moment, his massive semi-erect horse cock and snowglobe-sized balls refusing to cooperate.

As she was pulling her shirt back over her head, giggling at Matt trying to fit back into his pants and the thought of him showing up at the lunch table with a hoodie caked in 'sperm,' a crazy thought went through her mind. It wasn't just that she'd known Matt since they were born. She felt safe with him, she trusted him more than anyone else in the world. She _loved_him.

Would that be crazy? Would it be crazy for him not to just be her first time, not just her best friend, but her... boyfriend? Wasn't that, in a way, already true? What would she do with a boyfriend that she wasn't now doing with Matt?

Ellie tried to put the thought out of her mind as Matt finally finished getting his clothes back on. There would be plenty of time to think about that later. For now, they had to hurry back home for Bob's big lunch.

Still laughing, the two adolescent shire horses scampered down the treehouse ladder and ran back to the house.

The amount of cards Jennifer held in her hands was almost comical. It had to be twenty at least, but it was too many for an exact count. She shook her head and smiled. What else could she do?

She looked up from the massive deck she was holding at her mother and her aunt, sitting with her at the kitchen table. They held just five and two cards, respectively.

"You'd think with all those cards you'd be able to hit her with a wild draw-4," Jennifer's mom said to her.

"Or I could drop a reverse and hit you instead," Jennifer replied.

"She has more cards! One more and she'll have uno" her mom said, gesturing at Lindsey.

"Yeah I know..." Jennifer sighed, rifling through her cards. How was it that she had so many, but not a single one that she could use to attack with?

Finally, after much deliberation, she sheepishly played a blue five.

"Uno!" her aunt Lindsey said excitedly, playing her next to last card at the same time.

"Look what you let her do..."

"I don't have anything to hit her with," Jennifer said, almost resigning herself to the loss.

Her mom played a number card, and Jennifer again shuffled through her cards, looking for something that wasn't there. Her aunt Lindsey was tapping her fingers on the table and suppressing a grin. Poorly.

"Can't do anything," Jennifer said, playing another impotent number card, her only option. And as soon as she did, her aunt slammed down her last card on top of the pile.

"Boo-ya! Wild card! Winner, winner!" Lindsey shouted out.

"I always lose at this game," Jennifer said, thinking back on the previous years they had their annual pre-meal Uno battle. Every year she seemed to end up with half the deck in her hands when her aunt or mom or brother or cousin won.

Which reminded her, as she threw her cards onto the pile, that Matt and Ellie were still gone. Usually the five of them played while her uncle Bob cooked, but this year it was just the three of them.

"Lunch almost ready?" Jennifer called out to her uncle, who was stirring something in a pot on the stove top.

"Just about! Five minutes," Bob answered cheerily without looking up, "and we're eating whether the kids are back or not!"

He'd answered the question Jennifer was just about to ask. Her little brother and cousin had been gone a long time, ever since they opened presents that morning, even missing the yearly Uno game. What were they doing?

What_were_they doing? She felt like she already knew the answer. She'd had suspicions since her relatives showed up a few days ago, seeing how close and comfortable the two were with each other. Little hints, the way she was looking at him, a few things they said that Jennifer picked up on, and now an extended disappearance in which they were supposedly checking out an optical illusion book. Get real, who buys that? A convenient excuse. I know what's _really_going on between those two, she thought.

Which was fine, really. If Matt wanted to bone down their skinny little cousin that was between them. Jennifer had no jealousy; Matt was her little brother and her fuck buddy, not her boyfriend. As long as she got her share of that mega dick, Jennifer didn't really care who else got theirs.

Jennifer shifted her weight in her seat. There was something else that she was feeling, thinking about her little brother and her little cousin hooking up.

It was actually kind of hot.

Like, not the act in itself, she tried to justify to herself. Just the idea that her dorky little brother learned enough from her to go out and get pussy on his own. Or, at least, she may have given him enough confidence to act on something he'd felt for a long time.

But this was still all just assumptions on her part, Jennifer knew. She decided she would question him about it after their relatives left, but before that it might be a good idea to see if she could find any evidence on her own. How would she do that? Well, catching them in the act would be the most concrete proof, but what would be the best way?

The kitchen door burst open at that moment. With a gust of cool air entering from the outside, Ellie and Matt tumbled into the kitchen.

"We're not late..." Ellie started.

"Are we?" Matt said, finishing her sentence.

"Nope! Just in time! And you're in luck because we've got enough food to feed an army!" Uncle Bob said. He was starting to turn off the burner knobs and opened the oven to remove the turkey.

Matt's mom and Aunt Lindsey got up to help Bob start setting the casserole dishes and serving plates full of other items on the table, while Matt and Ellie sat down at their usual spots. For Matt, that meant next to his sister.

"You missed Uno," she said to him.

"Yeah, I guess we lost track of time."

"Doing what?" she asked.

For a second Matt didn't say anything, trying to think of a lie. He was looking forward to a massive Christmas feast, not thinking about covering his tracks from what he and Ellie had been up to.

"I was trying to show him how to see the Magic Eye pictures. He never got it. Then we explored the creek a little bit like when we were kids. Oh! And he braided my tail like when we were little too! Look!" Ellie said, answering Jennifer's question for Matt.

Ellie hopped off the dining chair she'd just sat down on and turned her butt towards Jennifer. She flicked her braided tail a few times to show it off.

"How come you never did that for me?" Jennifer asked facetiously.

"You never asked. I can, you want me to?" Matt answered.

"Maybe sometime," she replied.

"Might take a while with your big butt... oww!" Matt said, barely finishing before Jennifer kicked him lightly.

"Behave, you two," their mom said just as she set a basket full of homemade rolls on the table.

Matt stuck his tongue out at Jennifer, and Jennifer did the same to him. It was Christmas day and they were about to eat, they were both in a playful mood.

"All righty, here it is, the main event!" Uncle Bob said as he set the turkey on the kitchen counter. He still had to carve it up, but that would only take a few minutes. In the meantime Matt and Jennifer had already started loading their plates.

"Save some for me!" Ellie joked as she grabbed onto the spoon jutting out of the squash casserole.

"Plenty for everyone, feel free to stuff yourself to bursting!" Bob said without looking up from carving the turkey.

"You know plenty about that," Matt said quietly.

What happened then all but confirmed Jennifer's suspicions.

"Yeah, yeah, yeah..." Ellie responded to Matt.

Jennifer was just about to kick her brother again, assuming he was talking about her since he loved to make jokes about her size and today was the perfect day to get those in. But Ellie had assumed Matt was talking about her. Why, oh why, would Ellie assume Matt was talking about her when it came to getting stuffed?

But she already knew. It was obvious, Matt couldn't help himself from making little jokes like that.

And that was fine. In fact, it was kind of hot. But she'd have to keep Matt from being so obvious about this kind of stuff, or else their mom might find out, and she didn't even want to think about what would happen then.

Yeah, she'd keep an eye on him for the next day or so, and she'd have a good long talk with him after their relatives went home.

"Oww!" Matt said, dropping one of the honey-glazed rolls. Jennifer had kicked him anyway.

• -

The rest of Christmas day in the Shire household went on like previous years. They had all eaten way too much, so after lunch the afternoon was pretty low-key. All six of them played a board game, the game of Life, in the living room immediately after lunch; this was another Christmas tradition. The game was close but it was all over when Jennifer discovered a uranium mine and Uncle Bob was financially ruined by buying a helicopter. Matt came in 2ndplace, in part because during the course of the game he ended up having a total of seven children. None of them could have known it, but when they played again on Christmas day next year, the number of foals sired by Matt in real life would be close to that tally. None of them would own any helicopters or uranium mines, though.

After the board game, Uncle Bob sat himself on the recliner and turned on a football game. Him falling asleep before halftime of whatever football game was on was another Christmas tradition, it seemed. After single-handedly cooking the massive meal they'd all gorged themselves on, he deserved it.

Matt figured this would be the perfect time to finally check out his new Pretendo 64 games. When he suggested it, both he and Ellie bolted up to his room.

Jennifer watched them run up the stairs. A perfect excuse for them to be alone, she thought to herself. They'll be fucking inside fifteen minutes.

That's what she figured, anyway. And she didn't want to disturb them. But she did want to make sure, to know for certain. So after forcing herself to endure nearly twenty minutes of football, just as Uncle Bob started snoring, she got up and started up the stairs. Last time she watched so much football was a few months ago, and she'd gotten railed by half the team afterwards.

Her plan was just to go into the shared bathroom and listen for the telltale signs of sex. Since both her room and Matt's connected to the bathroom, that would be easy. But before she even got to the top of the stairs, she saw something she didn't expect. Matt's door was open.

She took it for granted that his door would be closed, the very least they could do to conceal themselves while getting busy, but no. There they were, she saw as she stopped and stood in the doorway - just laying on Matt's bed, innocently playing video games.

"Hey Jennifer!" Ellie called out to her.

"Oh... hey," Jennifer answered meekly. Her plan didn't include standing awkwardly in her brother's doorway.

"Sooo..." Ellie said after a longer-than-comfortable pause, "wanna play Space Fox 64 with us?"

"It's up to four players," Matt added in a way he considered helpful.

"You guys would kill me," Jennifer said.

"Nuh-uh! We just started playing!" Ellie answered.

"You can learn with us!" Matt said to reinforce Ellie's sentiment.

"I'm not really... into video games," Jennifer said.

"Excuses, excuses. Just one game," Matt said, never taking his eyes off the TV screen.

"Pleeeeease!" Ellie begged. Unlike Matt, she was looking straight at Jennifer. The way she said it reminded her a lot of Matt. If it weren't for that dump-truck booty Ellie would look just like her brother, Jennifer thought.

"Ugh, fine. One game," Jennifer relented.

"Yess!!" Ellie screamed, genuinely excited at the prospect of a three-way Space Fox battle.

Matt paused the game, then started to scoot over on his bed.

"Umm... how are we gonna work this," he asked. Matt was all too aware that his bed was barely big enough for just himself and Jennifer, so getting the three of them on it and comfortable enough to play video games would be a challenge.

"Maybe I could just lay on top of the two of you," Jennifer suggested, since her brother and cousin were both laying on their stomachs.

"You'd squish us!" they said in unison. "Jinx!"

Jennifer rolled her eyes. Yes, jokes about her size got old, but they were probably right. She was just a couple inches short of eight feet tall and weighed 350 pounds, while Matt and Ellie were both about 5'7" and _maybe_140 pounds each, even after eating all that turkey. Combined they weighed less than her, way less, so it their assertion that she'd 'squish' them wasn't without merit.

"Okay, well... I'll just sit like normal and you two can lay on my legs."

Matt and Ellie looked at each other. Often, they didn't need to actually speak to know what the other was thinking.

"That'll probably work," Matt said.

"Like laying on a big pillow!" Ellie interjected.

So Matt and Ellie hopped off the bed. When Jennifer sat on it the frame creaked, a familiar noise considering all the time she'd spent bouncing up and down in this very spot.

Matt handed her a controller. The wire barely reached when she was sitting with her back against the headboard of Matt's bed. Her little brother reset the game and, before Jennifer knew it, he and her cousin were back on the bed, on her, each one straddling one of her legs with their butts facing her. Matt was on her right leg, Ellie on her left, and their interior legs were crossed over each other so that they were kind of straddling her body, too. A minute ago, looking at her cousin and brother from the doorway, she couldn't help but think how similar they looked to each other. But from this angle - butts up - they couldn't have looked much different.

On her left, covered in skin-tight denim jeans, was her little cousin's thick ass. Ellie's hips were so wide and her butt so round that Jennifer didn't think she'd be able to use the controller without her left arm resting on it. She remembered how she looked just a few years ago, before puberty hit her like a truck. Was it normal for such a young mare to have such a thick ass? But then she remembered the same thing happened to her around the same age.

On Jennifer's right, by contrast, was her brother's relatively slim tush, covered by loose, baggy plaid pajama pants. Ellie's butt was definitely more attention-grabbing, accentuated by a newly braided tail, but then again Matt's butt wasn't exactly the most notable part of his anatomy.

Speaking of which...

Matt lifted his mid-section and butt up slightly. With the game controller in his left hand, his right hand went quickly down his loose pajama pants. Jennifer saw him do this a lot, in all kind of circumstances. Whenever he sat, laid down, or ever stood up sometimes, his dick just ended up in uncomfortable positions, so without even thinking about it he would manually redirect it down one of his pant legs.

As it happened, this time he directed his semi-erect (did he ever go soft?) horse-cock down his left pant leg. In this position, laying on Jennifer's right leg with his legs on either side of her, that meant it pressed against Jennifer's inner thigh with the tip just a few inches from her pussy. She could feel it against her, though most of the view was blocked by Ellie's right leg laying on top.

She couldn't help herself. Yes, she had fondled him just the night before during the movie, but she could never pass up any opportunity to feel up a cock, especially not one so delicious as her brother's. She reached down and grabbed hold of it as best she could, feeling that unmistakable heat through the thin cotton of his pajama pants. Her hand was near the base, just a few inches from those big balls visibly bulging underneath. Instinctively, though with no distinct goal in mind, she lazily stroked it up and down.

Matt looked back over his shoulder with a smirk. He saw the lustful grin on his sister's face; he was in bed with two hot mares who he could fuck any time he wanted. For a horny teenage colt, this was heaven. He stuck his tongue out at Jennifer while lifting his butt just a little to give her better access to his dick, and she stuck her tongue out back at him while gripping his shaft just a little tighter and stroking just a little faster.

"We ready to play?" Ellie said without taking her eyes off the TV.

"Let's do it!" Matt replied.

So began their first of many, many rounds of multiplayer battle in Space Fox 64. Even though none of them had ever played before, Matt and Ellie were leagues better than Jennifer due to her total lack of video game experience. Most rounds saw Jennifer losing quickly, then the remainder of the battle continuing between Ellie and Matt until one of them pulled out a victory.

Despite losing first every time, Jennifer found that she was actually having a lot of fun. Maybe that was just because every time she lost she got to put down the controller and feel up Matt's hard shaft, fat balls and soft butt. Still, she had to admit that there was something fun about playing these 'stupid games' her brother was always obsessed with. Maybe they could play some together when her relatives went home.

The trio were having so much fun that they completely lost track of time. It wasn't until several hours later that Ellie's mom wandered upstairs and peeked her head into Matt's room that they realized it was almost dark.

"You kids having fun? You've been up here all afternoon," she said to the three horses laying on the bed.

"Yeah! This game is super awesome!" Ellie answered. Her mom looked at her for a second, but Ellie didn't avert her eyes from the screen. The three of them laying in a pile on the bed didn't raise any red flags for her, since there really wasn't any other way for the three of them to be on the bed and play the game at the same time.

"I'm surprised you managed to rope Jennifer into playing this long with you two," Lindsey said after a moment.

"It actually is really fun. I think they've turned me on to video games," Jennifer said.

"Aww yeah, eat it!!" Ellie called out suddenly. She'd beaten Matt and won this round. "Hey! Wanna try it with us? Up to four players!"

"I don't think so..." Lindsey answered. Video games were for children. "I don't think there's room enough for me on the bed anyway."

"Scared you can't handle it? Scared you'll get your butt spanked?" she heard her little nephew reply.

Her eyes darted from her daughter to Matt, who was looking at her now in a way that was part devious and part horny. That little twerp. That cute little twerp with his adorable little butt up sticking up, swishing his tail, that cocky grin and that cocky... cock he was packing.

"If I can figure it out anyone can," Jennifer said.

"Please, mom? Pleeeeeeaaaaase??" Ellie begged.

Whatever. It's Christmas, Lindsey thought.

"Fine, fine. One game."

"Yessss!!" Ellie squealed.

"But I'm not getting on that bed with you, I don't think the frane can handle it."

"I dunno, this bed can handle a lot!" Matt quipped. Both Lindsey and Jennifer assumed he was talking about having sex with them on the bed and froze for a moment.

"Just get a chair from the kitchen. The controller will reach," Ellie offered as a suggestion, breaking the tension she didn't know existed from Matt being a bit too cavalier about what else had gone down on this bed.

"Good idea. Be right back," Lindsey said.

A couple minutes and a quick explanation to her own puzzled sister and husband later, Lindsey was back in Matt's room with a controller in her hand.

"All right now, what do all these buttons do," she asked, staring down at the strange device.

"You'll figure it out," Matt said, completely unhelpfully.

"Move with the stick. This button here," Ellie said, holding up her controller, "fires your gun. The rest is pretty easy."

"It's easier than it looks. You learn as you go," Jennifer said. After just a couple hours she had gained a lot of confidence in her skills. Maybe with her aunt playing she wouldn't lose every time.

"Here we go!" Ellie said as she started their first 4-player game.

A few minutes and a lot of furious action later, it was all over. Ellie won, Matt came in second. Jennifer was ecstatic that she didn't lose this time - third place! And, as expected, her aunt Lindsey came in last.

But she had fun.

"All right, one more game," Lindsey relented after her daughter asked her please again. But one game turned to several and several turned to dozens, and before any of them realized it, the skies outside were totally dark and it was well into the night.

It was around 7:30 when Bob leaned into the room from the doorway.

"I've been hearing whooping and hollering all afternoon from up here, you guys must be having a big time!"

"I think I understand why the kids spend so much time on these things now," Lindsey said without looking up.

"I believe it! Just came up here to let you guys know that dinner's ready, come down whenever you get the chance. And after that we can have movie night, if you don't want to continue playing this," Bob said, ever-accommodating.

"No way, we can't miss movie night. What are we watching?" Ellie asked.

"A classic. Live Hard. You guys haven't seen it, have you?"

Lindsey had, of course; Bob was a film aficionado and she had watched all his 'classics' with him over the years. None of the three younger shire horses had seen it, though.

"We'll be down after this game, honey," Lindsey said to her husband.

"Okee dokee, sounds good!"

About five minutes later and the last match of Space Fox 64 had concluded with another Ellie victory and Lindsey loss. The four of them headed downstairs to the kitchen to help themselves to some of Bob's fabled 'Holiday Turkey Chili,' something he whipped up every year to have a light dinner after such a big midday meal. Rather than eating at the table everyone helped themselves and made their way into the living room, where Bob was queuing up the VCR in preparation for movie night.

"You guys are gonna love this one," Bob said, having set everything up for movie night. All he had to do was press play.

"What's it about?" Matt asked right as he finished the last spoonful of chili from his bowl.

"It's about this cop who finds himself in a terrorist hostage situation, kind of a wrong place wrong time deal. But he's the kind of guy who takes matters into his own hands! Lots of action, lots of suspense. Plus," he said, gathering the empty bowls from everyone around the room to take back into the kitchen, "it's a Christmas movie!"

"How is a cop fighting terrorists a Christmas movie?" Ellie asked, handing her empty bowl to her dad.

"Because it takes place during the Christmas season! You'll hear a lot of people say it's not a real Christmas movie, but I'm in the 'yes it is' camp. Once you see it you'll get it. I won't spoil anything else. We ready?"

"Sure, let's watch it!" Ellie answered.

So while Bob took the dishes into the kitchen, the five family members made their ways to their respective familiar movie-watching stations. Jennifer took her seat on the floor in front of the couch. She was already covered with the huge blanket she expected to conceal her anticipated activities with her brother. She lifted up the corner, imploring him to join her underneath it without asking directly.

"Actually I... think I'm gonna stay on the couch. The floor gets a little uncomfortable after a while," Matt said, to the surprise and severe disappointment of his sister.

"Won't that be a little crowded?" She asked, trying to find an excuse for him not to ruin the cock-fondling experience she had been looking forward to all day.

"It's fine, I can sit on the recliner," their mom said, unaware of the struggle she was unwittingly inserting herself into. "Plenty of room on the couch for two."

Ellie could barely contain her excitement as Matt's mom got up off the couch, leaving the other larger blanket as she went. Ellie quickly threw it over herself and Matt.

"Hmmph..." was all Jennifer managed to utter as she pulled her own blanket tight, sitting on the floor just in front of her cousin and brother. Her face betrayed her dejected feeling, though she was making every effort not to show it.

"All righty, we ready to start the movie?" Bob said, walking over to the light switch.

"Yep!"

"Start it up!"

"Hit play!"

"Hmmph..."

• -

Jennifer couldn't focus on the movie, not even a little bit. Her long equine ears flicked back every few seconds; there were some strange noises coming from just behind her on the couch. Nothing overt, and nothing she would have heard if she wasn't specifically listening for it. But it was there.

It was about 20 minutes into the movie - right around the time the first big action scene started - that Ellie went from sitting on the couch to laying down on it.

"Don't tell me it's boring you!" Bob said loudly, necessary because of the constant gunfire in the movie.

"Nope! Just getting more comfortable!" Ellie answered.

Up until then Matt and Ellie had been sitting normally on the couch, though both were covered by a single large blanket. But when Jennifer heard Ellie rustling, then saw her laying down in her wide horse's peripheral vision, she knew what was up.

As soon as the movie started and Ellie pulled that blanket over them, Jennifer's little brother and cousin had been covertly exploring each other with their hands. Ellie's blue jeans were too tight for Matt to get into, but their tightness made her legs feel so nice. Ellie didn't have the same problem. Matt's pajama pants were so loose that she was easily able to get a hand down them and around that thick shaft. About a minute later, with her coaxing, it had gone from semi-erect to rock hard.

She directed Matt's hand off her thigh and down, right between her legs. She was winking, hard enough to feel even through the layer of denim between her pussy and Matt's hand, and she wanted him to feel it.

"Pow, pow! Bang, bang!" Her father called out with laughter when the shooting started in the movie.

"Zap, zap..." Ellie said in response, winking her equine pussy for Matt in time with her words, just as she had in the treehouse that morning.

Soon she found herself subtly and subconsciously rolling her hips, weakly humping Matt's hand that she still held in place. She was unbelievably wet, almost soaking through the thick denim already. Why was she so horny this time of the month, her 'super horny' time? Whatever, that didn't matter. She knew how to cure it now.

So, when the shooting in the movie started, she'd tipped over on her side to lay down on the couch. She was too horny to think about the danger, the fact that she was in the same room as her mom, dad, aunt, cousin, and if any of them found out what she was doing her life would be over. That didn't even register with her. All she could think about was the fire that was burning in her. The heat. And the only remedy she knew to extinguish it.

Matt shifted over an inch at a time, trying to time his movements with the sound of gunfire and explosions in the movie. Ellie's legs were in his lap, hips so thick that her butt went all the way up to his chest while she was laying on her side.

Ellie, with the hand that wasn't still holding his to her winking pussy, was tugging on his arm. She wanted him to lay down horizontal on the couch behind her, for reasons that weren't too difficult for Matt to figure out. But laying down with her immediately would have been too obvious, he thought. With his whole family in the room he had to be subtle.

He thought about just going for it, but then the first big action scene was over and the movie went back to a slower pace. Slower and less noisy - not good for making a move like the one he was planning.

"Hans Hoofer is a pretty bad guy, huh?" Uncle Bob said at one point, a tense moment where all the hostages were being questioned.

"Looks he's got his hands full with John McClyde though," Ellie said from the far end of the couch.

"Looks that way! But just wait," Bob answered back with a laugh.

"There's no way they could track him down in that huge building," Jennifer interjected. "He could be hiding anywhere in the Naka... what's it called?"

"The Nakadashi Tower," Bob answered.

"Yeah, Nakadashi Tower. It's too big."

Soon the next big action sequence started up. Gunfire, glass breaking, the works - this was the chance for Matt to make his move. While everyone else was distracted, he tipped over like Ellie had done a few minutes before, their two bodies totally covered by the thick blanket. Ellie shifted forward to give him more room to slide up behind her. Just a wiggle, a slide while a henchman fired a machine gun, and... success.

Only their heads protruded from the blanket, Matt's resting on his cousin's shoulder. If either of their mom's or Bob looked over nothing would seem too peculiar, just a couple cousins watching a movie while they lay on the couch. But what the two were up to underneath the blanket was anything but innocent.

By the time the action scene ended, Matt's entire arm was up Ellie's shirt. His cousin may have been flat as a board, her chest almost the same as his own, but rubbing his hands over her nipples was just as exciting to Matt as feeling up her small-breasted mother or his sister's massive tits.

It was entrancing to Ellie, almost narcotic. All the lines she'd crossed and new experiences she'd had with Matt over the past few days left her primed and ready. No one had ever felt her like this, no one had ever made her feel wanted like Matt. _Loved_like Matt. Again her mind went back to that crazy thought: what if they could be more than cousins? More than secret lovers? What if they could be in a real relationship, boyfriend and girlfriend?

That was a question for another time. Right now, Ellie had more in mind than just getting handsy with Matt under the blankets. Despite the risk, despite the fact that her mom was only a dozen feet away and Jennifer was close enough to touch, she was too horny to wait. She needed dick. Right now.

Matt was not expecting Ellie to do what she did next. He'd thought things would go about as far as they had with Jennifer on previous movie nights - a little touching, a little groping, maybe some mutual masturbation, but nothing further. What Ellie was dong now though suggested she had a lot more in mind.

As quietly as she could, Ellie unbuttoned her blue jeans. Slowly, so slowly that no one else would hear, Ellie started easing the zipper down. She didn't do it all at once or else the sound would be a dead giveaway. In a series of nearly a dozen little movements that took almost a solid minute, Ellie worked the zipper down, down, down. All the way to the bottom.

The next part would be more difficult. The zipper on her pants was just a little thing, but now she had to get those pants (along with her panties) off her hips and down at _least_to her knees. That would probably be far enough; she didn't need to take her pants off entirely. Her goal was just to give Matt unblocked access to her pussy so he could fuck her from behind. He'd still have to get that monster out, but with those loose and baggy pajama pants he was wearing that would probably be pretty easy.

Matt felt her shifting her weight in front of him, lifting her hips a bit off the couch. It didn't take him long to figure out what she was doing.

Ellie had gotten her pants down a few inches when she felt Matt's fingers on her back side, just above her tail. That made her realize that she had forgotten the button fastened above her tail, which would have stopped her progress and been difficult to unfasten herself without making a lot of ruckus. With a flick, Matt unbuttoned it.

"Teamwork," Ellie said out loud. The scene playing in the movie had the protagonist John McClyde in communication with and being helped by a sympathetic police officer on the ground outside Nakadashi Tower, so her comment made sense in the context of the movie. It was too perfect an opportunity for her to resist.

"Makes the dream work!" Bob called back, clueless as to what Ellie was really talking about.

"Definitely..." Ellie said. At the same time she made a pretty big movement with her body and hips. She was trying to make it look like she was readjusting to get more comfortable on the couch, but really she needed a big movement like this to get the weight of her body off her jeans. She pulled down on one side of her pants and Matt, understanding instinctively what she was doing, tugged down on the other.

Jennifer winced. Maybe no one else in the room knew what was going on behind her, but she definitely did. She heard the button, the zipper, the denim on fur-covered skin as the blue jeans slid off Ellie's hips and to her upper thigh. It was a little shocking to her that Ellie and Matt would be this brazen right here, right now, in front of everyone, but she also had to admit - it was really hot.

She had been disappointed when Matt didn't sit with her for the movie, but not jealous. Again, there was no need to be jealous when it came to Matt fucking Ellie. He was just her brother. The two had no compunction - neither her or her brother - to not sleep with anyone else they wanted besides each other.

So instead of jealousy, Jennifer found herself starting to get turned on by the thought of Matt fucking Ellie right behind her. Her finger found its way down her own pants, over her large mound and clit, into her pussy. She winked once involuntarily at the situation, the thought of Matt's huge cock inside what she imagined was a pussy several sizes too small for it. Then she had another thought that was even hotter: would he be as stupid with Ellie as he had been with her? Did he think it was safe? Would he cum inside her?

Of course he would. Of course that idiot little brother of hers would cum inside his cousin while she was in heat (it was obvious, Jennifer could smell it). It was pretty much a certainty he already had. And of course, Jennifer knew, part of the blame for that was on her. Hadn't she been telling him it was safe for the past month or more? Hadn't she been letting him creampie her daily for weeks on end? She was the one who filled his head with nonsense about 'safe days' and downplaying the risks, only because it was already a foregone conclusion for her. It didn't matter any more. She wasn't going to get any 'more' pregnant no matter how much cum she let her brother dump into her.

But Ellie... that was a different story. She was in heat, so if Matt came inside her there was a serious risk of her getting pregnant, even if they just did it once. And as Jennifer knew, that was all it took - Matt knocked her up the very first time they had sex. So there was a very real risk that right here, right now, right behind her head, her little brother might be just about to impregnate their cousin.

And that thought was hot as fuck.

I really am a sick puppy, Jennifer thought to herself. I really should try to stop this. I could just lean over and tell them I can hear them. I could whisper it, no one else would know. And doing only that, just the bare minimum, might prevent Ellie from making a life-altering mistake. That's what a normal sister would do, right?

But Jennifer wasn't a normal sister. The thought of her little brother fucking Ellie, his bulbous cock-head ballooning out inside her and filling her little 'cookie' was making her wet. The thought of Matt fathering another foal with their teenage cousin in the living room during movie night, with the whole family right here, was making Jennifer wink uncontrollably. So she twisted her ears every few seconds as she slid her fingers in and out of herself and rubbed her big horse clit as quietly as she could.

Behind her, Ellie had managed to get her jeans and panties off her hips and down her thighs. Matt was pulling them down further, slowly enough to not make enough noise for Ellie's mom, Bob, or his mom to hear. That Jennifer might be listening - let alone silently encouraging him and masturbating at the thought - didn't cross his mind.

All of a sudden there was a loud explosion in the movie, then the start of a gun battle. Another action scene! Another opportunity to mask the noise!

So Matt, now just as horny as Ellie with his cock dripping precum, pulled down hard on Ellie's jeans. With their parents distracted by the movie, Matt knew he had to act fast. Ellie helped him, lifting her legs a bit to put the weight back on her hips and pulling her pants down from the other side. She knew she didn't need to take them completely off. That wasn't the goal. She just needed to remove enough clothing to be able to present her pussy to Matt and spread her legs enough for him to wedge his cock inside. Weirdly, it was a little bit like going to the bathroom to pee. You didn't need to take your pants completely off or remove your shirt for that, and for the same reason. All that was needed was unobstructed access to her cookie.

With a final tug Ellie's jeans and panties were down around her knees. Matt felt her big butt, her wide and fertile hips pushing back against him. She was grinding her hips rhythmically and pushing Matt into the back cushion of the couch. Ellie was so eager and ready that she couldn't help it.

Matt, too, was so horny that he could barely think. Unbeknownst to him, the blanket he and Ellie were under had trapped all of Ellie's scent, the pheromones released while she was in the peak of her estrus. When he moved to help her take her pants off his nose dipped under the blanket and his nostrils filled with chemical lust.

He had been so focused on helping Ellie get her pants off that he hadn't considered how he was going to get his cock out and into position. Right now it was, as usual, directed down one of his pant legs. He'd have to get his own pants down at least to his knees to get it out, since the unflared but dribbling tip of his rock-hard horse cock extended that far down his leg.

Fortunately for Matt it was a lot easier to pull down his loose and baggy plaid pajama pants than it was to peel Ellie's skin-tight jeans down her legs. But he would need to hurry; these action scenes only lasted so long, and if he wasn't able to get his pants down and his cock out by the time it was over he'd probably have to wait until the next one. When a series of massive glass windows shattered in the movie, Matt made his move.

First he had to push Ellie's big butt forward. The way she was pushing it back into him and grinding made it nearly impossible to move otherwise. Once she felt him pushing on her she understood what she needed to do, which was fortunate since Matt wasn't strong enough to push Ellie off him if she didn't want to move.

When Ellie pushed her hips forward, Jennifer felt the blanket behind her head press into the back of her neck ever so slightly. It was enough, though. The noises, the movements, the whiff of a scent... she could surmise what was happening at every step. From her own experience she knew it was a task for Matt to maneuver his cock even in ideal circumstances, so there was bound to be a bit of commotion when he swung it into position and between Ellie's legs.

Jennifer, listening intently and masturbating secretly, didn't have long to wait. The gunfire in the action scene was reaching a crescendo and Matt knew he had to act quick. He started by pulling his pants down in the back, over and down past his butt - easy enough since there was no buttoned clasp over his tail like their was with Ellie's jeans. From there he tugged down on the front, and in a few more seconds the elastic waist was down to his hips, his balls, his shaft, more of his shaft, and finally to his thighs.

Now was the tricky part. Trapped in its current position, his cock was like a coiled spring; once the elastic waistband cleared the tip, it would recoil up with considerable force, enough that if it wasn't impeded it would slap loudly against his chest. He would have to manage that recoil manually.

But Ellie was already on it. She was new to sex, having lost her virginity just the day before, but she had an instinctual knowledge and need to get bred. She and her chosen mate were working towards the same goal, and she was going to help any way she could.

Ellie flexed her leg, lifting it a few inches and pressing it back against Matt's. At the same time her hand went to the gap between their legs just above Matt's cock. Now when it was released from the elastic waistband, the only place it could go was the direction they were both working to channel it: between Ellie's legs.

A loud explosion boomed in the movie. Without hesitation Matt chose that moment to free his monster horse cock from elastic waistband restraint. It hit the bare back of Ellie's thigh without making any discernible noise, since it only cleared about an inch of space between Matt's pants and her leg. Ellie deftly pushed it down the back of her leg to her inner thigh while raising her leg a few more inches, leaving a smear of precum on her flank.

But then it all went wrong. Suddenly the spring-loaded cock found the empty space between Ellie's legs that both she and Matt were directing it towards. Without any further resistance, it sprung forward, and with an audible slap it hit Ellie's belly. As a reflex Ellie's legs came together again, gripping the base of Matt's cock like a vice between her thighs.

Everyone heard it. By sheer bad luck, Matt's cock slapped into Ellie just a second or two after the climax of the big action scene that had just occurred, while everything was still on fire but the scene was quiet. Everybody heard Matt's cock slap against Ellie's stomach. There was no missing it. But the instant it happened, only Jennifer recognized what that sound actually was and what it meant.

* Clap! Clap! Clap!*

"Bravo. What an action scene. This movie _slaps..."_Jennifer exclaimed. She'd quickly pulled her hands up from her pussy and out of the blanket, making a point to clap slowly but loudly and in an exaggerated way to make sure everyone could see it - and assume the first slapping noise was just her clapping her hands.

"Told you it was a classic! Yippee-ki-yay, Merry Christmas!" Bob answered with delight.

Matt and Ellie were frozen with trepidation, literally holding their breaths. Had anyone else heard? Did anyone else know?

But then a minute passed without anyone saying anything. The cousins started breathing again, their heart rates slowed. Then another minute passed. Everyone else was watching the movie like nothing had happened.

Slowly Matt realized that they were in the clear. What a fortunate turn of events, he thought. Jennifer just happened to be enjoying the movie so much that she started clapping at the exact perfect moment to provide an alternative explanation for the noise! Matt was so naive that he didn't even consider the other possibility, the truth of the situation - which was that his sister was fully aware of what was happening just behind her head and that she was actively running interference and covering for him to help him fuck their cousin.

Ellie also didn't linger too long on what had just happened. With a 14-inch horse cock clenched snugly between her thighs, rubbing against her pussy, her actions by this point were being guided almost entirely by her arousal.

That said, she wasn't willing to risk going all the way just yet. With the end of the action scene, the movie was again fairly quiet and subdued, with tense scenes of suspense rather than gunplay and fireworks. They would have to wait for the next action scene before their own action scene could start.

That didn't mean Ellie couldn't do anything, though. The object of her obsession was between her legs and jutting out in front of her. It would be criminal not to play with it.

Matt felt his cousin wrap her hand around the end of his cock. He was dripping like a leaky faucet, enough slimy precum to coat Ellie's fingers in seconds. She started rubbing up and down, glazing more and more of Matt's veiny black equine penis with its own natural lube with every stroke. Again she started pushing her butt back into Matt and rolling her hips, grinding now not just on his body but on the thick shaft she gripped with her hand and between her thighs.

Matt also knew they would have to wait until the movie got loud again before going any further. That was all right, though. He didn't mind the position he was in now. He slid his hand up onto Ellie bare hip, up because her hips were wider than his shoulders by a good margin. From there he wrapped his arm around her, pulling her butt into him. He began thrusting lightly, matching his speed with the slow and subtle rolling of Ellie's hips.

He explored her body further, something he never got tired of. He felt the steep contour from her hips to her slim and toned stomach, twirling the little patch of thicker horse hair just below her navel, a feature he shared in common with her like so many other horses. His hand went up to her flat chest again, her nipples that didn't protrude at all from the rest of her body. Ellie bit her lip, trying not to make any faint moans; Matt feeling her up did it for her like nothing else.

The mixture of the constant drip of Matt's precum and the similar amount of fluid flowing from Ellie's pussy and down her leg now coated the entire length of Matt's cock. Ellie's inner thighs were similarly coated with their slick juices, so much that Matt's slow humping sent his cock sliding smoothly between her legs and across her winking slit.

For nearly fifteen minutes the two cousins continued on like this - slow and measured moves that served only to increase their arousal more and more. They were waiting for that next action scene, the next chance for the sounds of what they were working towards to be masked and muffled. And all the while Jennifer was listening intently, aware of exactly what they were doing and pleasuring herself at that knowledge.

"Here it comes, the best action scene of the movie. You kids ready?" Bob said suddenly.

"Oh I'm sooo ready for some action..." Ellie answered, rolling her hips and pushing back hard against Matt, his cock gripped firm between her thighs. She felt the heat from his huge balls against the back of her legs.

"That's my girl! I knew you were an action junkie!" Bob cheered.

"This is the Shire family, Uncle Bob. In case you didn't know, we're all 'action' addicts," Jennifer said, though she immediately regretted it. Maybe that was a bit too on the nose.

"I guess I married into the right family then!" Bob said, clearly not picking up on the double meaning. Jennifer breathed a sigh of relief, hoping no one else picked up on it either. Sometimes she just got carried away in the moment without really thinking things through, but that was just who she was. Maybe that was just another Shire family trait.

Then..._ BANG! _

A huge explosion kicked off the action scene Uncle Bob lauded as the most intense in the entire movie, followed instantly by a cacophony of gunfire, hero grunting and villain screaming.

Now was the time. Both Matt and Ellie understood it and without any hesitation began to act.

Ellie shifted her body forward, as close to the front of the couch as she could; if Matt was going to maneuver the flat-headed end of his 14-inch cock into her they would need every inch. She un-clenched her thighs, lifting one up to set her cousin's shaft free and expose her frantically winking horse pussy. With her right hand she reached behind her to the base of her butt, pulling up hard to spread her pussy for Matt to give him the biggest target possible.

Matt's hand whipped from Ellie's belly back to his shaft. He had to scoot his body towards the far end of the couch - right now the base of his cock was on Ellie's pussy, so he needed a good ten inches or more of clearance before he would be able to get the tip inside her. He hooked his hooves under the back cushion and bent his knees, pulling his body down in relation to Ellie. His head, which had been just behind Ellie's, was now behind her upper back.

What's more, his entire body was now completely underneath the blanket. If anyone else in the room had looked back at him at that moment he may have been discovered, but fortunately everyone else had their eyes glued to the TV watching the flashes and fireballs from the movie. Everyone except Jennifer, anyway; she was masturbating furiously now, ears turned backwards.

With his entire head under the blanket Matt was also exposed to the concentrated chemical cocktail coming from his procreant cousin. He didn't think about where he was, who was in the room, or why he had every reason to slow down and take his time. All that was in his pheromone-flooded mind now was getting his cock inside Ellie.

Ellie felt Matt fumbling around with his cock behind her. He had to align it manually, she knew that from previous experience. She pulled up on her butt cheek harder, trying to help him out. His dripping, dimpled cock-tip poked her left butt cheek, then her right, then right under her tail above her tail-hole.

'Come on. Get it, get it in. Put it in my cookie' Ellie thought. She considered whether she should grab onto it herself to help Matt find the target, but instead she just pulled on her butt ever harder to spread her pussy lips more.

'_Come on, Matt! Get it in! Come oo-_OOOH MY GOD!!" Ellie screamed out as Matt finally found his mark and rammed most of the length of his cock into her pussy in one brutal thrust.

"Crazy, right? Non-stop action!" Bob chimed in after hearing Ellie scream out.

"Yeah-h-h, mmmhf... cra-azy..." Ellie managed to exhale. Matt had started humping, in and out, faster and harder than she was expecting. Was he nuts? It wasn't just the unexpected thrust, he was humping her so hard now that she could hear the sloppy sound of his dick plunging in and out of her sopping-wet pussy. And if she could hear it, others certainly could too. The big action scene was covering for them now, but it would soon be over.

She pulled the blanket tighter, off of Matt's face, and bopped his nose with the back of her head. That nose bop - along with his nostrils no longer being immersed in the overwhelming scent of mare in heat trapped under the blanket - brought Matt back to his senses.

And not a moment too soon.

All of a sudden the big action scene was over, the main antagonist of the movie Hans Hoofer falling off the Nakadashi building to his ultimate demise. And with that, the movie was quiet again.

Matt and Ellie froze. They were in a precarious position, Matt's cock medial-ring deep inside Ellie. Almost any move they made would be audible now.

Jennifer also froze at the same moment. With her equine ears flipped backward she had clearly heard the moment her brother plunged his cock into their cousin. Ellie did a pretty good job of hiding her exclamation, but Jennifer recognized it for what it was. The gushy wet sounds of sex she knew so well that proceeded just confirmed her suspicion. It was so hot that she had been masturbating almost loud enough to be heard herself, but the pause in the action made her stop just as fast as Matt and Ellie. What would they do now, she wondered. The danger and the risk, even if she was experiencing it vicariously, was so hot she could barely stand it.

It was like that time their mom almost caught them, when she was riding Matt's cock on his bed one night and their mom knocked on the door. He was just about to cum when that happened, and even though they both froze when their mom knocked Matt still finished inside her. That's probably how it'll play out now between him and Ellie, she thought. He can cum even when he's not even fucking, like filling up a car at the gas station, a deep horse cum injection. And that's probably what he'll do.

Ellie had other plans, though. Matt had been too aggressive at first, but now more than a minute had passed after the end of the action scene without him moving a muscle, despite him being as deep as he could go inside her. She would have to take charge.

She reached back to find Matt's hand, then pulled it back to her belly. Then slowly, methodically, and above all else quietly, she started rolling her hips.

Though to say that Ellie was 'rolling her hips' would be doing her a massive disservice. Her movement was so slight that almost all of the 10-inches of horse cock she was grinding on stayed inside her, yet so deliberate that it felt to Matt like the entire length of his shaft was sliding in and out of her. He thought about the times his sister would bounce on him; it was almost like being underneath an pile-driver with Jennifer, a piston in and out as far as she could go both ways, a significant portion of her 350 pound frame on top of him with each drop. That was fucking. But what Ellie was doing was much more sensual. It was less like a piston and more like a warm ocean wave washing over him in regular intervals. And every few seconds, to punctuate the experience, her winking pussy gripped Matt's cock with a warm tightness that Jennifer could never compete with.

Quite simply, despite her lack of experience, Ellie was a natural. She was built to milk cum from horse cocks, her body was made to bear foals, and every part of her now was working towards that goal.

Now that he was thinking straight again, Matt was content to let Ellie do the work. She was pushing him into the back cushion of the couch with each rhythmic undulation. He put his hand back on her wide foal-bearing hips, feeling the large and powerful glute muscles under her skin flex and relax in time with her movements. He was probably about as strong as Ellie when it came to his arms, but her legs and butt were so much stronger than his, and it was times like these that really drove that point home.

That lower body strength and poise was being channeled, primarily, into keeping their sex as silent as possible. Now that the movie wasn't filled with explosions and gunfire, every move the two cousins made had the potential of being heard. This was the other part of why Matt was content with Ellie taking charge here - she just moved a lot more gracefully and, frankly, athletically than Matt. Riding cock with the finesse of a gymnast was totally in her wheelhouse.

But no matter how good she was she couldn't keep what she and Matt were doing totally silent. They weren't making enough noise for the other three horses in the room to hear, but Jennifer, with her ears pivoted behind her and listening specifically for it, was just able to make out what she thought was the sound of horse cock splitting mare pussy. She couldn't believe that they would risk continuing without the movie masking the sound, but evidently her little cousin was really skilled at sneak-sex. Maybe she could pick up a few pointers? The idea of openly talking to Ellie about fucking Matt sounded pretty hot. Everything that was happening right now, in fact, was super hot. Jennifer just hoped she could keep her reckless masturbating as quiet as her cousin and brother fucking behind her.

Matt could feel himself getting close. If Ellie kept going like she was going he wouldn't be able to stop himself from cumming within the next minute. He was aware that doing that might create some new problems - chiefly related to the pure volume of cum he would be pumping into Ellie. It usually made a lot of noise when he softened up and half the load came gushing out. But was there really any other alternative? In their current position they were effectively stuck. One of them would have to slide up or down the couch to dislodge his cock from the muscular crevice it was in.

Matt slid his hand back up Ellie's taut body, over her smooth stomach with just the hint of muscular abs underneath, then back to her completely flat chest and little black nipples. Ellie, in turn, reached behind her and grabbed on to Matt's slim butt. She started pulling him into her with each gyration of her hips. Neither she nor Matt noticed Jennifer breathing hard on the floor just in front of them, or the fact that her ears were flipped backwards.

"You guys ready for the grand finale?"

Jennifer's ears snapped to her right, to Uncle Bob.

"I thought the last scene was the finale? Hans Hoofer fell off the building," she said.

"That's just what they _want_you to think! But all his henchmen are still roaming all over Nakadashi Tower, determined to succeed in their evil plan whether their boss is alive or not..." Bob replied, sounding almost like he was trying to do a voiceover for a movie trailer.

"Spoilers..." Lindsey said, gently poking her husband in his ribs.

"Sorry. Well, anyway, there's one more big action scene to look forward to," Bob said. His wife poked him in the ribs again.

"Is it about to start?" Jennifer asked expressly for the benefit of Matt and Ellie to plan their next moves.

"Yeah, about five minutes," Bob answered.

"Just watch the movie, guys..." Lindsey said, this time without poking Bob in the ribs.

Jennifer was happy with that answer, thinking it would provide her brother and cousin enough time; she rotated her ears back to start listening for their telltale noises again. But for Matt it was a different story. Ellie's masterful, elite-tier hip-roll smooth riding on his cock was so good that he was rapidly nearing orgasm. If she kept on like this even for another 30 seconds he wouldn't be able to hold it any longer, let alone five minutes.

Ellie, despite her seeming natural-born talent at milking cum from horse cocks, did not have the experience to recognize the subtle signs that her partner was about to release said cum into her; her instinct was to ride cock until she was full of cum, not predict when that would happen. So while Matt was struggling to hold off his impending, imminent ejaculation, Ellie was oblivious.

Matt couldn't risk even a whisper to warn Ellie. His hand went back to her toned stomach and he pulled her body into his, the only thing he could think of to try to alert his cousin that he was on the verge of cumming.

But Ellie misinterpreted this. Completely.

She placed her hand on top of Matt's, urging him to pull her into him even tighter. She sped up her smooth rolling motion, Matt's cock moving inside her but only an inch or two of his lower shaft sliding past her pussy lips while the majority stayed firmly gripped deep inside her. To her this was just Matt - who she already viewed as being her official boyfriend - being affectionate and loving, pulling her closer in a moment of intimacy.

Matt couldn't hold it any more. He gripped Ellie tighter, pulling her into him even harder, so hard that Ellie had to stop herself from wincing. Even that didn't alert her to what was about to happen.

A rush of endorphins flooded over Matt as he was unable to postpone his orgasm a second longer and finally surrendered to it. Ten inches deep inside Ellie, as deep as her tight, virgin-until-yesterday pussy would allow Matt's 14-inch monster to delve, the flat head of Matt's equine cock mushroomed out to three times its normal width, like a closed fist suddenly spreading its fingers wide or a flower bud blooming all at once.

The feeling was a new one for Ellie, experienced for the first time just last night, but it was unmistakable. Her eyes rolled back in her head as she achieved near instantaneous orgasm, pure and refined chemical pleasure as her body bathed her brain with its own flood of dopamine, the primeval reward for allowing herself to be mounted and mated. Instinctively she stopped rolling her hips and pushed her butt back into her mate, pinning him against the back of the couch and holding him there so that he would cum as deep inside her as possible.

Jennifer heard a muffled moan, so quiet that she wasn't sure that's what it was. But there was also a rustling, a sudden jarring spasm of Ellie's hip, and just inches from her ear what she thought could only be the sound of Ellie's teeth grinding together to stifle a scream. Oh fuck, Jennifer realized. That's it. Holy shit. Matt's cumming inside Ellie.

Jennifer had been edging for a while, on the cusp of masturbatory orgasm herself and backing off over and over again, but when the moment (and Matt) came she couldn't contain it any more. Now she was the one with her eyes rolling back in her head, clenching her teeth, trying to remain still and quiet while an orgasmic earthquake of pleasure rolled over her.

Like a gush from a hand-operated water pump, the first terrific jet of horse cum erupted from the exposed urethra buried deep inside Ellie. Just this first pulse was enough to completely flood his fertile young cousin's womb and start to stretch it, expanding her from the inside and swelling her belly.

Ellie's clenched teeth started chattering, her body quaking in ecstasy. This feeling, being spread and filled from the inside, warmth radiating like love from her cousin-turned-boyfriend, the incomparable experience of 'getting spermed,' as she would say... it was nothing like she'd ever experienced in her life before yesterday. And now that she knew how good it felt, she'd never stop wanting it.

For Jennifer, if there was any doubt about what was happening behind her, Ellie's spastic movements eliminated it. Even though Ellie was doing an excellent job staying quiet, her almost vibratory motion could be felt through the couch. Jennifer was trying to suppress her own orgasmic tremors while listening to the two young horses behind her. Her eyes darted left and right to her uncle, aunt and mother to make sure they didn't see, hear, or feel anything, but all three were still intently watching the TV screen.

Matt was riding his own orgasmic wave, not as intense as Ellie's but just as gratifying. His flared horse cock pulsed a second time, another potent jet of cum filling his cousin's uterus and stretching it from the inside like a water balloon. With his hand on her stomach he could feel her belly expanding. He pulsed a third time, and again her stomach stretched. It reminded him of inflating a beach ball when they used to go to the ocean in the summer - with each breath it would get a little bigger, the skin a little tighter. Now instead of breaths blown into a ball it was cum pumped into a womb, but Ellie's stomach was bulging and her skin stretching in the same way, just a little more with each spasm of Matt's cock and each additional risky injection of horse semen.

Ellie's orgasm began to subside, her eyes re-focusing on the room around her and the quaking of a body in bliss waning. In the place of ecstasy a warm contentment spread through her, a sense that she was doing exactly the right thing right now, fulfilling a core purpose of her existence. She never connected the dots that this was related to her 'super-horny' time of the month. Her heat. All she knew was that it felt good, that Matt assured her it was totally safe and that he loved her like no one else ever had. And that made it okay.

With Matt's hand on her stomach and her hand on his, she could feel each additional tensing and flexing of his cock inside her. Every time his cock pulsed she knew another stream of her cousin's 'sperm' was being shot into her. Feeling her own belly expand just a little more was confirmation of that.

She scanned the room just as Jennifer was doing at the same time. There was no indication that anyone else knew what was happening. Ellie looked at her mom, but Lindsey was focused only on the movie. What would she say if she knew what was happening right under her nose, Ellie wondered. But there wasn't much danger of that, not anymore. The way they had done it was nearly completely silent. Now there was no movement at all except for the ever-weakening pulses of Matt's ejaculations.

Ever-weakening, and eventually stopping altogether. After more than a dozen pulses, Matt was finally finished. Ellie felt his hand slide back up from her noticeably distended belly back up to her flat chest and nipples. Such a loving partner, she thought. Then she felt his hard cock, still deeply implanted inside her, begin to soften.

Alarm bells. The sudden realization hit her: they may have been able to stay quiet when they were having sex, but every other time in the past day Matt had filled her up with cum, when it was over and his cock unflared and softened and retreated, at some point the absolute pressure of all that liquid inside her would forcefully eject the 'cork' of Matt's cock. This was inevitably followed by a splashing cascade of cum spewing out of her. This, she recognized now, would be almost impossible to hide.

In a panic she slammed her legs together, trying to keep Matt's cock in place. If they could make it to the next action scene they might be okay. The sound of explosions on the TV might just drown out the sound of the deluge of cum.

Matt, whose head was still swimming in post-coital bliss, did not immediately understand what Ellie was doing. But when she grabbed onto the back of his butt to try to pull him closer to her he finally got it.

He let go of Ellie's stomach; he couldn't afford to put any additional pressure on her. Just as she was grabbing his hips, he grasped hers and pulled her into his lap. His cock was getting softer and softer by the second. He tried thinking horny thoughts - Ellie on all fours in the treehouse came to mind, butt up, legs spread, tail lifted. The same image with his sister, his aunt... his mom. They all looked the same from behind, just different sizes and proportions. Different flavors of the same delicious dish.

But it was no use. No matter how much he thought horny thoughts or tried to flex his dick, after just ejaculating he was going to go soft. No matter how tightly he and Ellie pushed and pulled against each other, they weren't going to make a water-tight seal. His cock was coming out, one way or another, and with it a torrent of cum. Their only hope was to hold out as long as possible.

"Is the action coming?" Jennifer asked. She knew the timeline of events associated with taking a load from her little brother. They were in a precarious situation. But she was determined to help in any way she could. Maybe that meant a fake coughing fit or something. That wouldn't be ideal for covering up the specific sound of cum spewing from pussy, though. For now she just asked Uncle Bob when the last action scene of the movie was, the last chance for Matt and Ellie.

"Patience!" was Uncle Bob's vague answer. Not what Jennifer was hoping for.

Matt and Ellie's arm muscles were straining now. Ellie crossed her hooves, legs clenched together as tight as possible. But it was a losing battle.

Another 30 seconds ticked by. Just as slowly as a snail - and arguably even slimier - Matt's cock was slinking out of his cousin. The flared and dimpled head, a dam against the turgid reservoir, was also shrinking. At some point very soon the dam would break. That was inevitable.

Matt could feel it. It was about to happen. Nothing he or Ellie could do would stop it. In a panic his mind raced through bad options. Should he just pull out and get it over with? Maybe jam part of the blanket in there? Or his hand? Was that even possible?

No matter, he was out of options. It was coming. Now.

"Here it comes!" Bob yelled suddenly.

And a second later, the Christmas classic Live Hard saved the day. Our hero John McClyde fired a rocket into a helicopter. The helicopter crashed into Nakadashi Tower with a great and deafening boom, followed by gunfire, then a dramatic trumpet trill from the soundtrack. In short, auditory chaos.

Auditory chaos! Hallelujah!

Both Ellie and Matt understood that now, right now, was the moment to act. They let go of each others' hips. Matt pulled his body back into the couch cushion, Ellie unclenched her legs and thrust her hips forward.

_ Boooom!! _

A massive explosion, the biggest of the movie, as the detonators that were key to Hans Hoofer's hostage plan exploded violently and deafeningly on the roof of Nakadashi Tower.

_ Sploooosh!! _

Matt's cock was powerfully ejected from his cousin's pussy. A waterfall of cum followed, powered by the compressive force of Ellie's deflating belly. It splashed against Matt's stomach, the couch, the blanket - everything. Everywhere.

Jennifer heard it clearly. But she had her ears rotated backwards, and she was listening out for it. As explosions and gunfire continued to boom from the television, she again scanned the room. Uncle Bob, Aunt Lindsey, her mom. Had they heard?

But none of them turned away from the action on the screen. Not one.

With cum dripping down Matt's stomach and balls as well as the back of Ellie's leg and butt, the two cousins remained motionless. Just like Jennifer, they were looking at the three adults in the room, waiting for any indication that they had been caught.

But none came. Seconds ticked by. A full minute. Gradually it became more and more clear to them - they had gotten away with it. They'd fucked right in front of their entire family and no one had been the wiser.

No one except Jennifer, of course. But Ellie and Matt didn't know that. And fortunately for them, she was an ally they didn't know they had.

Cleaning up had been the hardest part.

More precisely, cleaning up to the extent possible while keeping their actions secret had been the hardest part. The movie ended just five minutes after Matt's cock and nearly half a liter of cum had been discharged from Ellie's winking horse slit. In that time Matt had managed to pull his pants up and use the plaid-patterned cotton like a towel to soak up as much spooge as he could. Fortunately the color and pattern of his pants - dark red with black patterning - made it difficult to tell which parts were wet and which were dry. From a distance, anyway.

Ellie employed the blanket itself to clean up her crotch and backside. Her denim pants did a less adequate job of hiding the fact that they were drenched. She tried to keep them dry but it was no use. There was just too much liquid covering her lower body.

"So how did you kids like it? Was that a Christmas movie or what?" Bob said with a smile, getting up to turn off the VCR and turn on the lights.

"Definitely a lot of action," Ellie said.

"And a lot of noise," Jennifer added.

"I'm still not sure that was actually 'Christmas movie...'" Jennifer and Matt's mom said, expressing an opinion that everyone in the room except Bob likely shared.

"I'm inclined to agree..." Lindsey said.

"What? You guys are crazy, did you see the wreaths? The decorations all over Nakadashi Tower?" Bob said in his defense, still smiling, knowing it was a controversial but fun-to-argue opinion.

"Just because a movie is set during the holiday season doesn't make it a Christmas movie..." Jennifer said, agreeing with her mom and aunt.

"What! You too? Everyone ganging up on me," Bob joked. "Ellie! Matt! You guys agree with me, right? _Live Hard_is totally a Christmas movie."

"Sure, Dad, I'll be on your side. _Live Hard_is 'totally' a Christmas movie. One-hundred percent," Ellie said with an air of playful sarcasm.

"Huzzah! Wise choice, daughter of mine! And you agree with us, right Matt?"

"Uhh... sure. I'll be on your side,_Live Hard_is for sure a Christmas movie.I feel like I owe you that much, Uncle Bob," Matt said.

"My favorite nephew! It's a tie then, three for and three against. Always a polarizing topic," Bob said. He didn't pick up on Matt's words or consider why Matt thought he 'owed him' anything.

Aunt Lindsey shot Matt a cold look. _She_knew, but only half of it - the half that involved her cheating on her husband and taking two creampies from their nephew. She did not know that her nephew had also fucked and creampied her daughter _four_times in the past 24 hours, including once just minutes ago.

"Well, anywho... good Christmas! About time to hit the hay, I reckon!" Bob said. Everyone in the room squinted when he flipped the light switch. Fortunately for Matt and Ellie, still underneath the blanket, no external evidence of their activity was apparent.

Matt waited until Jennifer started getting up to crawl out from underneath the blanket. He figured he could use her big body as a shield to hide himself from view from the rest of the family. With any luck he could make it to the other couch and under his own blanket without any interference.

But, fortune of fortune, as Matt crept out from under Ellie's blanket, Jennifer stood up with the other blanket outstretched. Matt just accepted it as good luck, but in reality Jennifer was pretending to start folding it specifically to block Matt from view.

"Oh yeah, you need this to sleep tonight. Here," Jennifer said, draping the blanket on Matt and wrapping it around him to completely obscure his body and, as she could see now, the soaking wet pajama pants he was wearing.

"Oh! Th-thanks!" Matt managed to say, shocked at his good luck, unaware that this 'luck' was actually his sister actively assisting him and Ellie.

"No prob," Jennifer said. But her task wasn't done. She looked down at Ellie, covered up with her own blanket on the couch with just her head sticking out. She knew what that blanket was concealing. There was no way Ellie could get out from under it, so she would make sure she didn't have to.

"You sleep in those Yumbro shorts, right Ellie? I'll get them for you," Jennifer said, looking down at her cousin. She saw Ellie's eyes go wide in relief and appreciation. God, these two, Jennifer thought. They are so obvious it's painful.

Jennifer quickly went into the kitchen, then into the laundry room where Ellie had her luggage, just one small travel bag with clothes and toiletries. She grabbed a pair of her Yumbro shorts and went back briskly into the living room to deliver them to her.

"Here you go," she said, almost stuffing the thin polyester shorts under Ellie's blanket.

"Thanks a ton Jennifer, I..." Ellie started.

"Don't worry about it," the nearly 8-foot-tall Shire replied down to her cousin.

Jennifer thought Ellie still wearing cum-soaked jeans might be a problem, but in truth no one else in the room remembered or cared what Ellie was wearing underneath the blanket. It was time for bed. Jennifer's mom was already up the stairs heading to her bedroom with Aunt Lindsey right behind her. Uncle Bob was standing near the foot of the stairs waiting to turn the lights off.

"Oh yeah! You kids want the Christmas tree lights on. And the music!" Bob said, remembering how his step-daughter and nephew had slept the night before. The Christmas tree lights had been turned off while they watched the movie, so he'd have to come back into the living room to plug it in, then go back to the cabinet near the TV to turn on the CD player.

"I'll get it! I'll do both!" Jennifer blurted. Before Bob had a chance to object she was already at the Christmas tree. "I can turn out the lights, too! You can go ahead and go upstairs Uncle Bob!"

Her actions struck Bob as a little eager, but he didn't think anything of it.

"Okee dokee, suit yourself! Night kiddos!" Bob called out from the foot of the stairs.

"Night Dad!" - "Good night Uncle Bob!" Ellie and Matt answered simultaneously.

Jennifer plugged in the tree. Once she did her Uncle Bob turned out the lights, since the light from the tree provided enough for her to see. She went over to the CD player and hit play.

"Volume good?" She asked. Ellie was rustling under her blanket. She must be taking off her jeans and putting on her Yumbros, Jennifer thought. Probably mopping up a bit with the blanket, too. She made a mental note to wash the blankets the moment her relatives left for home tomorrow.

"Perfect. Thanks Jennifer," Ellie said.

Jennifer looked at her brother but he didn't answer, he was adjusting something underneath his own blanket. That was fine. He could thank her later in a different way.

"No prob," Jennifer said again. "Good night you two."

"Night!" - "Night!" her brother and cousin said, again simultaneously.

Jennifer started up the stairs, but paused when she got to the top. From this angle she could look down on them but she was in total darkness. She wondered... would they be audacious enough to fuck again tonight?

Really though, she knew the answer almost before the question formed in her mind. Of course they would. With the lights, the music, it being the night before Ellie was going home - of course they would.

It was 11:15, and if Matt followed the same rules with Ellie that he did with her, he'd wait at least 30 minutes before making a move. Probably 45 to be safe. Right around midnight. And if she were to sneak out of her room around that time, creep to this very spot at the top of the stairs in the dark behind the banister, she just might get a front row seat.

She winked involuntarily as soon as the idea came to her. Hell yeah, she was gonna spy on her little brother fucking their cousin. Just knowing they were doing it behind her during the movie was hot, but watching them directly - that would be the hottest thing ever.

• -

"Come on. Hurry up. Inside. Hurry up! Finish inside!"

Matt's bed frame squeaked in regular intervals as it gently rocked back and forth, motion imbued by the mare riding horse cock on top of it.

"Come_on_Bob! Hurry up! Sperm inside me! Inside my cookie!"

Lindsey had started off kind of bored, but now she was genuinely annoyed at her husband. She just wanted it to be over with, for Bob to hurry up and cum in her so she could roll over and get some sleep.

"I'm trying honey... just-just keep like you're going now and it'll be a minute, maybe..." Bob said meekly. Lindsey had to have a certain tempo, fairly slow and gentle, to get him off. Too fast, too slow, too hard and he would go limp.

Lindsey looked back over her shoulder at her husband, a mix of frustration and disappointment in her eyes. She was riding him reverse cowgirl; she didn't even want to look him in the face at this point. Better to just look down at Matt's bed and focus on the task, riding Bob's cock at the exact right speed to get him off.

Matt's bed... Matt. That little twerp. That little twerp who absolutely ruined her husband for her. Bob would never be able to satisfy her again. Not after Matt. Not after she'd had that tower of a cock, that black, slick, veiny and throbbing and mind-breaking monster. Bob's little thingy couldn't compare. It wasn't on the same planet. It was almost half a foot shorter. When Bob flared, the tip was barely bigger than the width of Matt's shaft over its entire length. And his balls... my god, what a disgrace. Her nephew was packing nuts the size of softballs - genuinely as big as the softballs she'd pitched in high school, it was almost unbelievable how massive they were. Meanwhile Bob. Oh, sweet Bob. They were golf balls. Actually the size of golf balls. God, it was pathetic. No wonder, after years of trying, she was never able to get pregnant from him.

Still, as much of a chore as this was, she had to go through with it. If Matt did get her pregnant, she would need Bob to believe it was his. And that meant that, as much as she wanted to just quit right now and go to sleep, she had to keep riding cock.

"Are you close? Come on Bob!"

"I-I think so. Just keep going like you're going and I'll get there..."

"When?" Lindsey demanded.

"Maybe a minute. I... I think. Yeah, maybe a minute," Bob answered, clearly focused on his own 'task' just like his wife.

Lindsey kept bouncing, trying to keep up the pace she knew Bob liked. She tried to imagine she was on Matt's cock instead. But it was no use, even if she didn't have to look at Bob. He was too small. What's more, he never took charge. It seemed like 99 percent of the time when they had sex it was exactly like this: Bob laying on the bed doing nothing while she did all the work. Not like Matt. Yes, she had been the one running the show the first time, behind the store between the dumpsters, but that was more of an ambush than anything. When they'd done it properly Matt fucked her like no one ever had, with the possible exception of Ellie's biological father. Matt fucked her like she'd never forget, in any case, and like her husband would never be able to.

A minute passed. The bed kept squeaking. Bob continued to just lay there while his wife did everything.

"You close now?"

"Y-yeah, almost there... keep going..." Bob said, the strain in his voice evident.

Lindsey focused on keeping her pace constant.

"Come on. Come on Bob, sperm in me. Sperm for me. Sperm in my cookie..."

"I'm... I'm gonna..."

"Do it. In me. Inside me. Come on Bob, let it all out! Put a foal in me!"

"Nnnhhh..." Bob grunted. Even his grunts were subdued, Lindsey noted.

"All out. All inside me. Sperm me good, Bob. That's it, just like that... that's it..."

His flare was barely noticeable inside her, the only positive indication she had that Bob had actually climaxed. Almost immediately he started going limp, and in seconds his cock was almost totally soft. Lindsey lifted herself up and off her husband, rolling over on the bed next to him.

"You need to clean up? Or..." Bob asked.

Lindsey reached down to her crotch. Not a drop.

"Nothing to clean up. It must be all inside. Good job," she said to Bob, trying to assuage any negative feelings he might have about his lack of production. She remembered the absolute flood of cum that poured out of her when Matt fucked her. Meanwhile Bob couldn't even produce a trickle. Guess those massive balls on her nephew did their job.

"Well, that's good I guess."

Lindsey left it there for a moment before pulling the blanket tightly over her.

"Yeah, it is. Twice in two days, that's a lot for us. I have a good feeling about this." Lindsey finally answered.

"Think so? We've been trying for so long, I..."

"Yeah, I know," Lindsey said, cutting Bob off. "But I just have a good feeling about it this time. It just feels like this time is different."

"Well, who am I to argue with womanly intuition. I hope you're right!"

Lindsey left it there. The red LED of Matt's radio alarm clock showed 12:07. Another Christmas in the books

"Anyway, good night honey," Bob said after a few seconds of silence.

"Night, Bob," Lindsey replied. She closed her eyes and drifted off to sleep.

• -

Ellie's eyes were wide open. The room was illuminated dimly by the twinkling lights of the Christmas tree while holiday songs played softly. She was looking at the little digital display on the VCR, waiting impatiently for the display to tick over. 11:44 it said. And said. Still not changing. Still not moving.

It finally ticked over to 11:45 and she couldn't keep quiet.

"Now?" she whispered over to Matt.

"Not yet. We need to wait until midnight," Matt whispered back. It had been just over 30 minutes since everyone else went to sleep. He had no way to really judge it, but it felt way too soon to start another round of incestuous love-making. He and Jennifer usually waited an hour after their mom went to sleep.

"Midnight?! That's fifteen more minutes!" Ellie protested, her voice elevating almost out of a whisper.

"Better safe than sorry," Matt answered.

The word 'safe' spawned a new thread of thought for Ellie.

"If we wait until midnight it won't be Christmas any more," she said.

"So?" Matt said, not sure what his cousin was getting at.

"So, Christmas is a safe day. If we do it tomorrow it won't be a safe day any more."

Matt mulled this over in his head. It was something he had genuinely never thought about before. However, he was pretty sure that horse biology didn't work on a minute-to-minute basis, and it didn't make sense that things like pregnancy cycles would be that punctual.

"It doesn't work like that."

"Are you sure?" Ellie asked coyly, enough that Matt could tell that she was just playing around rather than being serious.

"Absolutely sure. Besides, tomorrow is a safe day too, so it's impossible for you to get pregnant," he said confidently. After all, his Aunt Lindsey had told him every day they were there was a safe day, so there was nothing to worry about.

"Still... maybe it's like - do you remember that movie Dad made us watch on Christmas Eve last year? The one from the 80's where the kid gets that little furry monster for Christmas?"

"Goblins?" Matt said.

"Yeah! Remember the rule? Never feed them after midnight? Maybe it's like that," Ellie said jokingly.

"I don't think that..." Matt started.

"Maybe," Ellie interjected, intentionally cutting him off, "maybe it's like, if you 'feed' your sperm to my cookie after midnight, I'll turn into a goblin..."

"You're already a goblin. Goblin' up my dick!"

"Gobble gobble!" Ellie laughed. "Or maybe it's like that old movie Cinderella. Remember she could only stay at the ball until midnight? Or else the carriage would turn into a pumpkin!"

"Uh-huh. I remember..." Matt answered, trying not to laugh. He loved how silly Ellie could be sometimes and how she could always surprise him and make him laugh with the crazy things she said.

"Maybe it's like that! If we do it after midnight and you sperm inside me, I'll turn into a pumpkin!"

"If it wasn't a safe day your Ellie-_belly_might turn into a pumpkin..." Matt said.

"Maybe! Good thing it's safe. But that wouldn't be the end of the world," she said.

That caught Matt off guard. Knocking up his cousin sure seemed like the end of the world to him.

"It... wouldn't?" He said.

"I mean, it kind of would..." she had to admit.

"Your mom would kill us," Matt said, thinking out loud.

"Yeah... but I mean, it wouldn't be the worst. Like, it would be a lot worse if I was some kind of _floozy_and did it with some random colt from school. If that happened he could just... disappear on me, you know? But if it was from you it would be okay because I know you'd always be there for me. Because you're my cousin and my best friend and we've known each other since we were like... old enough to remember."

"I guess that's true," Matt said, leaving it there. Ellie's tone had changed from silly to serious rather quickly and Matt wasn't sure where her head was.

A few minutes passed with the Christmas music from the CD player being the only sound. Matt quickly disregarded Ellie's last comment, instead thinking only about how long was long enough for them to be out of danger and have sex. But Ellie was working up the nerve to say what she really had on her mind.

"Hey Matt?" She said quietly.

"Hmm?"

"Do you... like me?"

Matt's eyebrows furrowed, though Ellie couldn't see it. What a weird question.

"Umm, yeah? You're my best friend too, you know," he answered in a matter-of-fact way.

"No I mean... do you like me, like me..." Ellie said.

Now Matt started to understand.

"Oh. You mean like a crush type of thing?"

"Kind of," Ellie said, before stating what she really meant. "Or like a girlfriend."

"Ohh," Matt said, thinking about his next reply for a moment. He decided pretty quickly that there was no harm that he could see in letting Ellie think of herself as his girlfriend. She didn't know about him and Jennifer - or probably more importantly, him and her mom. Plus she lived 4 hours away from him in another state and they only saw each other a few times a year, so it wasn't like he'd have too much trouble hiding anything from her. Sure, she could be his 'girlfriend' if she wanted to be.

"Well, yeah, of course. We're dating. That's what we are right? Boyfriend and girlfriend?" Matt answered, like it hadn't occurred to them that their incestuous relationship was anything other than a normal early-teenage courtship.

Ellie felt butterflies in her stomach. 'Dating,' he said. That was a word she hadn't considered before. It made her feel so grown-up. And he said he was her boyfriend. He said it himself. That made it official. She was his, he was hers, officially and exclusively. A couple. A real couple.

She couldn't stand it any more. Even though Matt had fucked her just an hour ago, she was already super-horny again - being in heat, her lust was absolutely insatiable.

Ellie threw off her blanket, the same one that covered them while they were having sex during the movie and which had its underside covered in cum. Before Matt could protest she was next to him and then, just as fast, she had crawled under his blanket with him, laying on top of him.

"It's still too early..." Matt protested feebly.

Ellie looked over at the clock on the VCR. 11:50.

"Close enough," she said. She could feel Matt's hard cock underneath her through her thin polyester sports pants and his trademark plaid pajama pants. Apparently it had been long enough for him to 'recharge,' and she didn't think he had much more complaining left in him now that she was under the blanket with him again.

"Maybe so..." Matt said, finally relenting, his libido overriding his sense of self-preservation.

Ellie tilted her equine nose up, closed her eyes, and pressed her lips into Matt's. Any shred of resistance he had to be safe and wait longer was melted with their kiss. For nearly a minute the two draft horse cousins made out passionately, tongues entwining and lips moving on their own. Finally Ellie broke their kiss and pulled her head up slightly. Matt opened his eyes to see her staring down.

"I love you, Matty-doo," she whispered.

"I love you, Ellie-belly," he whispered back.

They kissed again, just as intensely. Again, after a minute or two, Ellie pulled her head up and Matt found her gazing lovingly into his eyes again.

"You're my first boyfriend," she said quietly.

"And you're my first girlfriend," Matt said.

"I'm gonna miss you so much when I have to go home," she said to him.

"Me too. But you guys always visit for a week in the summer right?"

"That's like six months!" Ellie said with very real anguish.

"Yeah... maybe we could convince your mom or my mom to visit sooner," Matt said.

Ellie frowned, then dropped her body down entirely onto Matt. She rested her head next to his like they were hugging tightly. Matt wrapped his arms around her back, pulling her in close.

"I wish we were older. If we were old enough to drive I could just come down here on the weekends, no problem," Ellie said.

"We've still got two more years before we can get our driver's licenses," Matt said. Their respective birthdays were only one day apart, owing to the fact that they had been conceived within minutes of each other in the same room. Matt didn't know that, but the fact that they were almost the exact same age did mean that they would be able to start driving at the same time.

"Yeah. Until then we have to rely on our parents to take us to see each other. Like children," Ellie said with disdain. She wasn't a kid any more. She had a boyfriend, after all. She was dating.

"We can talk on the phone any time we want," Matt offered.

"Yeah, but that's not the same. And my mom listens in sometimes," Ellie noted, before turning more optimistic on their future. "But after we can drive we can visit all the time. And then after high school, we could go to college together!"

"That's a long time from now..." Matt said indeterminately. Ellie interpreted it as him wishing they were older, the same way she did. What Matt was really thinking was that it was pretty unlikely that, 4 years from now, Ellie would still consider him her 'boyfriend.' And he, of course, had no intention of actually thinking she was a real 'girlfriend' once she went home, let alone through 4 years of high school.

"I know. But wouldn't it be perfect? We could be roommates and our moms wouldn't think anything about it since we've always been so close. And we could have sex every single day..."

Matt felt Ellie grind on him ever-so gently when she said 'have sex.'

"That... does sound pretty good..." he said earnestly. Of course it was just Ellie daydreaming about things way too far out in the future for them to predict or plan, but the offer of daily sex did a lot for Matt to daydream along with her.

"We'd have to tell them eventually. Our parents, you know? But I looked it up; it's legal to marry your cousin in both our states," Ellie stated.

"Marry?!" Matt said incredulously. Ellie disregarded it and kept chugging along in her fantasy of their future together.

"Mm-hmm, it's legal! I looked it up! And we'd be adults by then so our parents might not like it, but they couldn't stop us. And I also looked on the internet and it's not true that if cousins have foals they'll be born with like, flippers for fingers. It's totally healthy for cousins to have foals, no problems. Even brothers and sisters or mothers and sons or fathers and daughters, there's no risk for a foal to come out wrong. That stuff only happens if you keep doing it for like... centuries. Like those royal families in medieval Europe with the chins that stuck out like..."

Ellie lifted her head up from next to Matt's so that he could see her again.

"Chins that stuck out like... durrrr!!" she said, jutting her own chin out as much as she could and shifting it to the side. She stuck her long horse tongue out of the side of her mouth for good measure, letting it dangle.

Matt couldn't help but laugh. When Ellie started talking about marriage and foals and how she did research on incest babies, Matt started to get a little bit worried. His cousin had a way of not taking anything seriously that was infectious, though. Even in Ellie's fairy-tale fantasy of them getting married and having foals, all that stuff was so far in the future that Matt didn't even have to think about it. Best to ignore it and focus on the part of her fantasy he _could_give her right now: sex.

Ellie's face returned to its normal, cute form and she laughed along with Matt.

"You can always make me laugh, that's what I like about you, Ellie-belly," Matt said.

"I like making you laugh. I like making you smile. I like making you feel good. That makes me happy," Ellie whispered back.

"You're really good at making me feel good," Matt said back to her.

"You're better at making _me_feel good," Ellie whispered.

"Yeah? How do I make you feel good?" Matt asked. He already knew the answer, but he wanted to hear Ellie say it.

"When you do that it makes me feel good," Ellie said as she moved her hands to Matt's. He had his hands under her shirt and was feeling up her stomach without realizing it.

Matt let his hands drift up to her flat chest, his thumbs gliding over her black nipples. Ellie took the opportunity to take her shirt off, letting it drop to the carpet next to the couch.

"These feel really good..." Matt said, caressing her nipples.

"They're too small..." Ellie said. It was the one part of her body she was self-conscious about.

"They're perfect. Everything about you is perfect," Matt said, laying the compliments on thick because he knew Ellie liked it. "Especially this."

Now Matt's hands went down to her thick, foal-bearing hips and her thick, muscular butt.

"It's too big..." she whispered.

"It's perfect," Matt answered.

Ellie just smiled in return. Evidently this was the right thing for Matt to say, because her response was to start taking off her thin polyester Yumbro shorts. When those were off she would be completely naked, so Matt took this as an opportunity to pull his own shirt off himself.

Under Matt's blanket, Ellie struggled a little with her shorts. Just like her jeans they were really tight; it was hard to find clothes for her proportions, with pants always being tight on her wide hips and thick butt. Eventually she was able to remove them, however, and she dropped them to the floor next to her shirt just in time to see Matt pull his shirt over his head and drop it next to her discarded clothes.

With Ellie now completely naked and Matt shirtless, there was clearly only one step left before they could get down to business. Ellie didn't want to struggle with Matt's pants like she did with her own though, and more importantly she didn't want anything to impede them when they started having sex.

To Matt's surprise, while he was working to take his pants off, Ellie gripped the thick blanket covering most of their bodies and, without any doubt or apprehension, tossed it right off of them and onto the floor.

This authentically shocked Matt.

"Ellie! What are you doing?!"

"It's fine, it doesn't matter," Ellie answered with certainty but without any explanation.

Matt, laying on his back on the couch, looked up at his totally nude cousin on top of him. She had a sly smile on her face. What did she mean it was fine? Without a blanket they were totally exposed.

"It's not fine and it does matter! What if your mom or my mom or Bob came down the stairs? They'd see us doing it!" Matt said, subconsciously not mentioning his sister, though neither he nor Ellie picked up on that.

"They'd see us anyway, just under a blanket instead of out in the open. It wouldn't change anything. Hurry up and take your pants off," Ellie demanded. She didn't wait for Matt to agree with her. She was too horny to waste any more time.

Matt wanted to mention how the blanket had done a good enough job concealing them when everyone else was in the room, so it was probably wise to keep themselves covered now. The couch was perpendicular to the stairs, with the armrest opposite their heads (the side their hooves and backsides were closest to) less than ten feet from the stairway banister. With the staircase in near total darkness and the living room illuminated by the Christmas tree, anyone coming down the stairs would be met with Ellie's bare-naked butt facing right at them. They'd be greeted by her black donut-like tailhole staring them down and, in a couple minutes, a clear view of a massive black horse-cock plunging in and out of her winking pussy.

But he could see Ellie couldn't wait any longer. And in truth, there was something perversely erotic about it. The risk of getting caught, the chance that his aunt or uncle or even his mom could walk down to the kitchen to get a glass of water and be met with the sight of their 8thgrade kids fucking wildly... that was hot.

Even just the fact that he would be naked and exposed in the living room was exciting in its own way, naked in a 'public' part of the house. He'd never done that before.

Until now.

With a quick yank Ellie pulled his pants down past his knees. This time Matt held onto his shaft so that it wouldn't rebound against his chest when freed from its plaid cotton prison. Exposed as they were, he had to be careful about making any unnecessary noise.

Ellie scooted on her knees backwards towards the far armrest as she pulled Matt's pants down to his ankles and then over his hooves. She dropped them to the floor on top of the discarded blanket. With that, the two young shire horse cousins were totally naked.

She looked down at her cousin's gigantic horse cock. Compared to his body it was disproportionately large to the point of seeming almost unreal. His body was still almost exactly the same as she remembered from their childhood: slim, no muscle tone whatsoever, more like a cute little colt than an adult. But that dick was bigger than anything she'd ever seen in pornos attached to muscle-bound stallions twice Matt's size. And those balls- so implausibly huge that she'd never seen anything like it.

Still, it kind of made sense. After all, her own body had matured in a way that wasn't too dissimilar. Her wide, foal-rearing hips against her table-flat chest seemed to be a total mismatch. Seriously, not even a hint of boobs, a chest that looked boyish. From the belly-button up she and Matt looked almost like twins. He might even look more girly than her, since she had just a little more strength and tone than he did.

Maybe that was just a trait that ran in their family. In the Shire family, puberty seemed to strike their genitals and core reproductive organs first and hard, leaving the rest of their bodies for later and working on them at a leisurely pace.

As she looked down at Matt's cute little body and the oversize, impossibly colossal cock attached to it, she was absolutely fine with this quirk of their family's sexual development. Given how much Matt loved both her flat chest and her thick hips and butt, he seemed to feel the same way. 'Perfect,' he had said about them both. That's how she felt about Matt too, both his sweet and innocent body and his mega-stallion monster cock.

That monster cock... she couldn't resist any longer. She reached down with both hands and wrapped her fingers around the shaft. Instead of stroking it, she just felt it, squeezed it, kneaded it like a contented house cat. Matt saw her eyes staring straight down at it, unwavering, almost covetous. It was like in one of those Kentucky Jones movies they'd watched last year where the archaeologist was obsessed with some ancient treasure and finally found it. His cock was Ellie's great prize.

"You like that thing a lot, don't you?" Matt said coyly.

"It's perfect..." Ellie whispered, her gaze planted solidly on the object of her obsession, Matt's cock.

"It's all yours. Whatever you want, whenever you want. Because I'm your boyfriend," Matt said, knowing that for whatever reason Ellie seemed to get really excited at the concept of him being her 'boyfriend.'

And mentioning it worked like a charm.

Ellie dove down onto his cock, closing her eyes and opening her mouth. She began to lick up and down its length, nibbling on it, letting it glide across her lips and into her mouth, then smear precum across her cheeks as she held onto it with her hands. It was almost as if she was hugging it - her nose, chin, the long flat length of her snout, forehead, ears... it was like she wanted every part of her face to touch it. She sucked on it at times, but what she was doing was definitely not giving Matt a blowjob. It was more akin to worship. The great prize, the mysterious artifact, the manifestation of her desire, the object of her obsession.

Matt just watched, letting her do as she pleased. With her face on his dick and her knees on the couch straddling his hooves, her butt was high in the air. It looked like a heart floating above her head. Her tail, braided from root to tip by Matt earlier that day, was hiked up so high that it was actually curling back on itself like a shiba inu. Matt always found that really hot, the way mares lifted up their tails when they were horny, an involuntary response to make it just a little easier for males to breed them by not accidentally blocking access to their pussy.

Probably a hell of a view from the staircase, he found himself thinking, with Ellie's butt pointed right at it. Forget that book in the treehouse, her puckered black donut would be the real 'Magic Eye' staring down whoever came downstairs now. And she was winking so hard Matt could actually _hear_it, even over the Christmas music.

Ellie lifted up her head and opened her eyes, looking straight at her cousin.

"I love you Matty-doo," she whispered.

"I love you, Ellie-belly," he answered automatically.

She shuffled on her knees up the couch towards Matt. He could see her pussy now, winking uncontrollably, begging to be filled. When her body was aligned to his she put her hands down on the couch on either side of Matt's head. She lowered her hips and Matt felt the weight and warmth of her butt settling down onto his lap. Her teardrop-shaped horse pussy made contact with the base of Matt's shaft, a few inches above his balls.

"I'm so happy... you're my boyfriend..." Ellie whispered.

She started rolling her hips again in the same splendidly controlled way she did when they were watching the movie. Matt looked down to see his cousin's pussy being spread slightly, rubbing up and down his shaft a few inches at a time as she grinded on him.

"And I'm your girlfriend... and I get to play with your thingy any time I want..."

Matt was used to her habitual childish euphemisms by now, so it didn't make him laugh. There was nothing childish about her sentiment or her intentions.

"And my cookie belongs to you..." she whispered, grinding on Matt's cock harder. To say she was dry-humping would be inaccurate, since she definitely wasn't dry. She was leaving a wet streak across Matt's cock. Rubbing up and down its length, coating it with her juices, her scent - it was like she was a wild animal marking her territory. 'This log belongs to me, everyone else stay away.'

"I want you so bad," she whispered, voice cracking with lust.

"You have me. You're my girlfriend," Matt said. He thought it sounded a little corny, but Ellie liked that kind of thing. The way she was grinding on his shaft, teasing him with her pussy, he'd say whatever she wanted to hear.

"I want you... inside me..."

"Put it in..."

Now Ellie moved her hips further, her pussy grinding on Matt's cock from the medial ring up its length, leaving a trail of slime all the way. Matt exhaled heavily with anticipation. He kept his hands on her ample hips as hers went to the flat tip of his penis. She inched her hips forward, arched her back. She guided Matt's hard cock to her entrance. Her black, plump equine pussy lips parted, and her boyfriend's cock, the great prize, the object of her obsession, slipped smoothly inside her.

"Oh god... oh, Matty..." Ellie huffed. "It's so big..."

Matt gripped his cousin's hips and gritted his teeth. No buildup, no easing into it. She started riding him, hard and fast.

He still wasn't used to how incredibly tight Ellie was compared to Jennifer, or even her mom. Over the past month and a half he had gained a lot of experience with his sister and could hold out for quite a while with her.

But with Ellie it was different. Her pussy gripped him so tight that he was lucky to last a few minutes before cumming. She didn't seem to mind. If anything she seemed to enjoy his climax inside her and being 'spermed' by him more than the sex. And since she had been a virgin before yesterday - and thought the same was true for Matt - she didn't have anything to compare it to.

For several minutes Ellie rode Matt, her pace and tempo nearly constant. She raised and lowered her upper body, arching her back in pleasure. Her hands went up and down her body, then up and down Matt's; she rubbed her flat chests, and at one point she reached behind her with both hands to spread her butt cheeks. But through the random and varied expressions of carnal ecstasy conveyed by her upper body and hands, her hips and lower body didn't waver. She kept the same pace, same smooth and rolling motion over and over and over like a machine; a machine designed solely to milk cum out of horse cocks.

And it was working. Matt, who was doing absolutely nothing but laying on the couch and holding onto his sex-goddess of a cousin, could feel that he wouldn't be able to stop himself from cumming if she kept this up much longer.

While Matt was girding himself against premature ejaculation, doing his best and struggling just to hold onto the bronco bucking on his lap, Ellie raised the bar even higher. On her knees straddling Matt, she wasn't able to get enough leverage to bounce on his cock as hard as she wanted. She widened her stance and let her left leg drop, planting her hoof on the carpeted floor next to the couch.

"Ellie... mmmfh..." was all Matt managed to get out. Ellie was riding his cock harder than ever, her thick and muscular thighs and butt working so hard that Matt almost felt like she was pounding him down into the couch cushions.

But fucking Matt into the couch wasn't why Ellie got into this position. Matt's cock was so long that she was unable to take the whole thing, so if she was directly on top of him their bodies would not be aligned with each other - Matt's face would be down near the lower part of her neck. So if she wanted to kiss him while they fucked, if she wanted to look into his eyes while he filled her with cum, she had to get creative with her sexual positions. And that was, as Matt soon discovered, exactly what she wanted.

Matt had been focusing on his cock gliding in and out of Ellie, a view he never got tired of, when his cousin's lust-stricken face filled his field of view. She put her nose to Matt's, then pressed her forehead to his so that their long equine snouts were touching at every point and their eyes were just inches apart.

"I love you Matty-doo... I love you..." she whispered liked a mantra.

"You're so tight," Matt answered, which was not exactly appropriate for what Ellie was saying but it was all he could think about at the moment. With each wink he could feel pulsating, involuntary contractions from her vaginal walls. They were moving in only one direction, starting at her winking entrance and rolling inwards, pulling on his cock like it was trying to swallow it.

"I want to be with you forever... my boyfriend... and someday my husband..."

Matt could feel that distinct tingling in the tip of his cock that he knew meant he didn't have long before he came. He thought he'd be able to hold out longer since it had only been an hour or so since he'd last ejaculated inside her, but that didn't even seem to matter.

"And we can live together in the city after college... and we can do it ever day..."

Matt was getting close. He could register that Ellie was saying something crazy about her fantasy of them spending the rest of their lives together, but he didn't have the mental bandwidth to process it. She was riding him too good and he was about to cum.

"And we can have eight foals... _ten_foals... as many as you can put in me..."

"Ellie... I'm gonna cum..." Matt squeaked out, something extremely uncharacteristic for him. This might actually have been the first time he told his partner he was about to cum instead of just doing it unannounced.

"_Do it!_Do it, Matt! Fill me up!"

"Nnnngh!"

Matt thrust his hips up an extra inch or two. His eyes closed, his hands wrapped around Ellie's back side and his fingers dug into his cousin's muscular butt, pulling her cheeks apart and exposing every bit of her to the room and staircase behind her.

"Sperm in me! Inside! Sperm inside my cookie!!"

Deep inside Ellie the tip of her cousin's black horse cock flared, spreading her from the inside. It blossomed like a flower, his dimples and ridges blooming like petals.

"Inside... sperm inside... let it all out inside me, Matt..."

Matt unleashed his first thick stream of cum inside her, a spray of millions of swimmers, each one searching frenziedly for an egg to fertilize. Ellie felt this as a sudden, fulfilling warmth being planted inside her, an addictive pleasure she'd never felt before last night but now associated wholly with Matt and her love for him.

"Yes... yes... all in... all inside... let it all out..." she panted in erotic relief.

Another flooding pulse, then another. Her belly began to expand, the only way her body could accommodate both the towering horse cock and tsunami of cum her half-brother was injecting into her.

"That's it... that's it, Matty-doo... fill me up... make me pregnant... put a foal in me..."

Matt's eyes opened in shock. Make her pregnant? What was she talking about? But he was midway through his ejaculation and couldn't stop. Even if he wanted to, he wasn't nearly strong enough to push Ellie off of him. So he pulsed again, pouring more cum into her. And again. And again. His cock flexed, his balls twitched, his tailhole puckered and spasmed, her pussy winked, all in clear view from the stairs if anyone happened to walk downstairs.

"Yes... yes... yesss..." Ellie whispered in orgasmic euphoria. Her stomach was visibly distended now, filled with his seed and plugged with his flared, engorged cock.

Another weaker pulse, then another. Matt's ejaculation was waning, a series of abating throbs and lessening releases of cum into an already-filled womb before, at last, he emptied his last dribble into his cousin.

He waited a moment for her eyes to meet his again; they'd rolled back in her head during her orgasm. He felt her hot breath on his chest.

"That was... so good..." she said after the last wave of hedonistic satisfaction passed over her.

"What was _that_about?" Matt asked.

"What?" Ellie replied.

"When you said 'make me pregnant?'" Matt said, trailing up in a question.

"Oh... I don't know. I just... I was thinking about us in the future. After college, after we're married."

Matt didn't answer. Ellie had very specific plans for the two of them a very long time from now, it seemed to him.

"But it's not like that could happen now. It's a safe day, so it's impossible for you to get me pregnant. As long as we have safe sex we never have to worry. And we've only been having safe sex."

Matt looked down his chest to where his raw, unprotected cock was still deep in Ellie's pussy, partially obscured by her bulging, cum-filled belly. Both of them were completely unaware of what the term 'safe sex' actually meant, but in their warped understanding of horse reproduction it made total sense.

"Yeah, you're right. Good thing we're being so careful," he said, believing it himself.

"Yep yep," Ellie said, cocksure and confident that she and Matt were being responsible, like adults.

She just smiled and looked into Matt's eyes for a moment before she spoke again. Even after sex, the feeling of him just being inside her was divine.

"I heard one time that safe sex doesn't feel as good as doing it when it's risky," she said. "Can you imagine what that's like? If safe sex feels this good, I mean. Risky sex must be amazing. But we'll have to wait until we're married for that. Until then, we can only have safe sex."

"Mm-hmm. Otherwise your belly will look like this permanently!" Matt said with a smile. He was just as positive as Ellie that they were having safe sex, so her comment in the heat of passion about wanting him to get her pregnant didn't worry him. The fact that she was so full of his cum that her stomach was protruding noticeably didn't either.

"Oh nooo! Matty, you rascally scoundrel! Rapscallion! Look what you did to me! What-ever will the townsfolk say..." Ellie joked, rubbing her belly for effect. It was all fun and games; once Matt softened and his cock was ejected along with half a liter of cum, her stomach would go back to normal. No need for any concern whatsoever, since they had safe sex.

"They'll give me high-fives because you're so hot," Matt said.

Ellie rolled her eyes, but when she saw the way Matt was looking back up at her she couldn't help herself. She leaned in and kissed him. It was less passionate than before they had sex but more intimate, less lustful and more loving.

After a minute-long makeout session Ellie pulled away gently, looking down at Matt. Holiday music was still playing, the lights from the tree was still twinkling, reflected in Matt's eyes. She had a belly full of cum and her boyfriend was still inside her. Everything in the world was perfect at that moment.

"We better be careful though. What time is it?" Matt asked, somewhat unexpectedly.

Ellie looked over to the digital display on the VCR.

"12:07," she said.

"Hope it's not like that movie Goblins. I fed you after midnight," he joked.

"Yeah you did. And it tasted so good..." she said, rolling her hips a couple times for emphasis. "Now I'm a goblin."

"A cum goblin," Matt suggested.

"Gobble gobble..." Ellie said in tacit agreement. "Or maybe you put a little Matty-goblin in me..."

She comically rubbed her belly again. Both she and Matt giggled and kissed again.

In a few minutes Matt's cock would slide out of her. Cum would splash onto the couch and Ellie's stomach would return to normal. She would go back to her couch, pull up her blanket and fall asleep confident that she and her cousin had been having 'safe sex' for the past two days.

She would later realize how wrong she had been, how her decisions during that Christmas visit would change her life forever. But that wouldn't happen for a long time. Tonight, everything in the world was perfect.

• -

Jennifer tossed and turned on her bed again. She was used to this kind of time-killing after going to sleep, since she'd usually wait about an hour before sneaking into her brother's room. Both she and Matt figured that was probably enough time to be pretty sure that their mother was asleep.

She wasn't sure he'd wait that long with Ellie, though. If they were brazen enough to fuck right behind her in the same room with their parents and with only a blanket and action movie noises to cover them, would they really be careful enough to wait an hour? Not likely.

She looked at the red display on the radio alarm next to her bed, identical to the one in Matt's room. 11:50, ten minutes to midnight and barely half an hour since she closed the door to her bedroom. If she knew her brother he'd probably try to wait until at least midnight at bare minimum, but Ellie might be able to 'persuade' him to start earlier. Either way, it was time for her to sneak out of her room.

Jennifer may have been nearly eight feet tall and weighed more than 350 pounds, but despite her bulk she was fairly well coordinated and surprisingly athletic when the situation called for it. She didn't make a sound as she rolled off her bed and gently let her hooves down on the carpet. She turned her doorknob slowly and opened her door quietly. She grew up in this house and knew every inch, so as she crept down the hallway, taking many seconds for every step, she knew which floorboards would creak and made sure to avoid them. It was pitch black, but she knew this hallway well enough for that not to matter.

It took her a solid three minutes of creeping at a snail's pace to make it from her bedroom doorway to the far end of the hallway, but she finally made it to the stairway leading down to the first floor and the living room where her brother and cousin were probably not sleeping. The hallway was dark, but the dim light from the Christmas tree in the living room below provided enough illumination for her to see the stairs.

Jennifer slowly lowered herself down on her haunches, then to her knees, each move glacially slow and measured to avoid making any sound at all. She needed to lower herself down so that she could peak past the first gap between the hallway wall and the banister, and to avoid detection it would be best for her to be as close to the floor as possible and for only her the very top of her head to be exposed.

To get into this position she needed to be down on her knees and elbows, her huge butt up in the air, almost like she was presenting herself to be fucked doggy-style. Fortunately this was a posture she was very familiar with. Five minutes after she rolled off her bed she was in position.

She edged forward slowly, deliberately. Her long equine ears peaked past the precipice, and a moment later she could finally see into the living room below.

And what she saw...

Every suspicion was confirmed instantly. On the couch that ran perpendicular to the staircase, below her and only about ten feet away, her sweet and innocent little cousin was naked on top of her brother.

Jennifer gasped and her eyes opened wide. She put one hand to her mouth to stifle any noise. She'd expected something like this, but she hadn't expected them to be out in the open without even covering themselves with a blanket.

From what Jennifer could tell, it looked like Ellie was giving Matt a blowjob. It was difficult to tell because her big butt was in the way of the action. Her cousin's braided tail was lifted high, curling back on itself to completely expose her tailhole and pussy. Jennifer didn't stare - she only had interest in stallions, colts, and massive cocks - but it was impossible for her not to notice how Ellie looked exactly like herself from this angle, just smaller. And with a braided tail. And with a black-lipped pussy flashing pink every few seconds as it winked and dripped.

As Jennifer watched, Ellie lifted her head up from Matt's crotch. She still couldn't see anything other than her brother's legs, but that was about to change.

Ellie started shuffling up the couch on her knees, away from Jennifer and the stairs and towards Matt's head. Matt's unmistakably huge balls came into view, then the base of his shaft. Ellie lowered herself onto it and started grinding up and down its length.

Jennifer felt herself wink. Propped up on one elbow, she stuck her other hand down her pants - the same kind of plaid pajama pants her brother wore, just a few sizes bigger. Maybe a dozen sizes.

She was already wet; the sight of her little cousin grinding on Matt's shaft was undeniably hot. There was another feeling though, as she watched Ellie rock her hips and glide up and down the meaty length she knew so well. Jennifer found herself wanting to encourage Ellie, to root for her like a fan of a sports team. She wanted Ellie to know how amazing it was. Cock as good as Matt's deserved to be shared, to be enjoyed by more than one mare. Get that dick, Jennifer found herself wanting to say to Ellie. You get that dick, girl.

Ellie lowered her head down next to Matt's. Jennifer could tell that she was whispering something to him, but she couldn't hear what she was saying. Her ears rotated and she focused on listening. But, almost like it had a mind of its own, her right ear rotated back the other way when she started listening intently. It was the remnant of an evolutionary adaptation, ancient horse ancestors who had to be weary of predators sneaking up behind them on the plains of Africa.

But the noise Jennifer heard behind her was no predator. And it wasn't coming from down the hallway, either. It was coming from inside Matt's room, where her Uncle Bob and Aunt Lindsey were staying.

It was her Aunt Lindsey's voice, but it sounded more like barking orders than the throes of passion. And there was something else. High-pitched, regular intervals. Of course, Jennifer realized. She'd heard that noise a hundred times before. It was the same creaking of Matt's bedframe she always heard when she was riding Matt. Her aunt and uncle... they were fucking!

You get that dick, girl! This house was turning into a sex palace and Jennifer couldn't be more on board!

Her attention returned to the scene in front of her. Ellie was sliding up Matt's body. Her hand was down between her legs. Her little cousin's hips moved all the way up to the apex of Matt's tool, the same one she knew had already put a foal inside her. Its dimpled head kissed Ellie's pussy lips, spread them, and smoothly and easily slid inside.

At the same time Jennifer pushed three fingers inside her own similar-looking but much larger pussy. This was easily the hottest thing she'd ever seen without being directly involved in.

"Get it... get it, girl... you get that big, bad dick... you go, girl..." Jennifer mouthed silently. She was on Team Ellie, experiencing it vicariously through her and cheering her own in secret.

Her ears rotated behind her.

'Come on. Hurry up. Inside. Hurry up! Finish inside!'

She distinctly heard her Aunt Lindsey's voice from inside her brother's room. It seemed like she wasn't the only mare in the family who preferred their partner to give them a deep creampie instead of pulling out.

Ellie was riding Matt hard now, and Jennifer could envision her mom was doing the same thing in the room behind her. Like mother, like daughter... what better way to cap off Christmas than bouncing on horse cock?

'Come on Bob! Hurry up! Sperm inside! Inside my cookie!'

Jennifer fingered herself harder. She could feel her juices dripping down her hand and thigh. She'd never thought of her aunt as being that much of a slut, but if she shared the same DNA as Jennifer it made more sense. Her daughter clearly shared the same horny genes as Jennifer.

Ellie lifted herself up a bit after a while, then planted one hoof down on the floor. She was riding Matt now in a position that was sort of half on, half off the couch. Matt was doing absolutely nothing, so far as Jennifer could tell, just laying there while Ellie did all the work. That fit well with what she knew about her brother.

Ellie's face went down to Matt's, and Jennifer assumed they must be kissing. She couldn't see any part of their upper bodies; Ellie's big, bouncing butt was in the way. The view she had from behind was pretty incredible, though. Ellie's braided tail was lifted, her large black donut-shaped equine tailhole pointed directly at Jennifer like a big eye staring her down. Below it, the cock she was so intimately familiar with was stretching and filling a pussy much smaller than her own. It was clear Ellie wasn't able to take the whole thing, never letting it fill her past the medial ring, but she was still riding it like a pro.

She saw her brother's hands reaching around Ellie's butt. They looked tiny in comparison to the size of her little cousin's big ass, wide hips whose purpose Jennifer was wholly aware of. Matt gripped both of Ellie's butt cheeks and spread them, giving Jennifer an even better view of his cock churning away, in and out of Ellie.

"Do it, Matt... do it... cum in her..." Jennifer mouthed while masturbating as hard as she could while remaining quiet, her legs spread and butt in the air like she was waiting to be next in line to be bred by Matt. "Cum in her pussy... cum in her... fill her up... knock her up, Matt... knock her up... get Ellie pregnant..."

Jennifer wasn't just rooting for Ellie to get that dick, she wasn't just cheering on her brother for getting laid. She was actively hoping that her brother would impregnate her cousin.

"Knock her up Matt... cum in her pussy... make her pregnant..."

She wouldn't be able to explain why, but the idea of her little cousin getting pregnant before high school excited Jennifer. Even more, the thought of her little brother breeding far and wide, spreading his seed and fathering foals with numerous mares was even hotter. Maybe if he got Ellie pregnant, there would be less focus on her. Maybe if he had foals with half a dozen other mares, Jennifer's world wouldn't come crashing down when her family found out she was pregnant and that her little brother was the father. She couldn't say. All she could say for certain was that what was happening right now was making her horny beyond belief.

"Come on Matt, do it... finish inside her..."

Another sound behind her caused Jennifer ears to swivel.

'Come on. Come on Bob, sperm in me. Sperm for me. Sperm in my cookie...'

Aunt Lindsey and Bob were getting close. Looking down to the living room, Jennifer could tell by hard hard Matt was clenching Ellie's butt cheeks that he was getting close too.

'Do it. In me. Inside me. Come on Bob, let it all out! Put a foal in me!'

Holy shit. Uncle Bob and Aunt Lindsey weren't just fucking, they were trying for a foal! Right behind her in Matt's room - on Matt's bed - a new niece or nephew might be conceived! And right in front of her...

She saw Matt's fingers clinch, digging deep into Ellie's butt cheeks. Ellie instinctively knew her mate was about to cum, so she stopped humping, dropped herself down as far as she could, and let the cock fill her to maximum capacity. She held still in that position, an eager receptacle for the life-creating flood she was about to receive.

The skin of the portion of Matt's shaft that was not inside Ellie, the base below his medial ring, appeared to tighten, tensing and momentarily revealing more clearly the ridge of his urethra. Jennifer knew instantly what that meant. He was cumming. Matt was cumming deep inside Ellie.

'All out. All inside me. Sperm me good, Bob. That's it, just like that... that's it...'

Behind her, Jennifer's aunt was taking a load from Uncle Bob. In front of her, Aunt Lindsey's daughter was being inseminated by Jennifer's own brother. She saw the base of Matt's cock pulse again, shooting another jet of hot, potent cum into the young filly, her wide hips indicating her fertility and suitability for the same thing her mother was begging Uncle Bob for. A foal.

It was all too much for Jennifer. She plunged her fingers into her fat pussy as far as she could and, in time with her niece, aunt, uncle and brother, she came. At the exact same moment all five of them reached orgasm.

Jennifer didn't shut her eyes as she came, watching Matt's pulsating cock as waves of pleasure crested and broke inside her. She winked and squirted, soaking her plaid pajama pants. It was astounding that Ellie was able to take it so well; Jennifer knew from firsthand experience how much cum Matt was pouring into her little niece. You get that dick, girl. Get that cum.

He was still pulsing inside Ellie as Jennifer's orgasm waned. She steadied her breathing to make sure she wasn't making any noise.

Then all was quiet. The only sound was the Christmas music still playing in the living room below her. Matt and Ellie weren't moving; her big butt was still up in the air, Matt's cock was still inside.

Minutes passed. Jennifer knew she should get up and head back to her room, but she couldn't risk it. Not yet. Any noise could lead to her detection. So she waited, silent and motionless. After a while she knew Matt would soften, and when he was soft enough Ellie's vice-tight pussy would eventually eject him - along with a cataract of cum. So she waited.

Until finally it happened. All at once and with a loud noise reminiscent of both the uncorking of a bottle of champagne and using a plunger to unclog a toilet, Matt's now soft cock was expelled from Ellie's pussy along with the unavoidable spew of cum. With the noise as cover, Jennifer rolled back and lifted herself up on her hooves.

Her ears stayed pointed behind her as she snuck back down the dark hallway, careful again not to step on any of the creaky floorboards. She opened her door carefully, slipped in, shut it behind her, and flopped down on her bed.

"Holy fuck," she whispered to herself. She thought she might catch a glimpse of Ellie and Matt having sex, but what she had witnessed - and heard - went so far beyond what she hoped for.

She smiled and started masturbating again. It would be a while before she would be able to sleep. Tomorrow her relatives would leave for home and she would be able to fuck her brother again. Should she tell him what she knew? What she saw?

Oh yes. Definitely. She'd let him know what she saw, what she heard. She'd tell him everything. His reaction would be priceless.

Everyone in the house was asleep. The red LED lights on the clock radios and the little display on the VCR all said 3:27.

That's the moment it happened. Whether it was from the most recent session, the one beneath the blanket during movie night, earlier in the day in the treehouse or even the night before when Ellie lost her virginity, it was impossible to say. The combined sperm cells of all the times over the past 24 hours Matt had creampied Ellie were all swimming around inside her, mixed together in a creamy, gooey mess. But whichever ejaculation it was from, the inevitable finally happened.

As Ellie dreamed, content in the assurance that today was a 'safe day,' a single sperm cell found the waiting egg inside her womb. A few hours later, while she still slept on the couch in her relatives' house, the holiday music played gently and the dim light from the Christmas tree twinkled on her face, that fertilized egg would implant in her uterus and begin to divide. When she woke up the next day, getting ready to head home, she would be pregnant, carrying Matt's foal inside her.

Just like her mother.
