Mareboi

By Ajax B. Coriander

Start: September 28th 2019

Finish: November 29th 2021

Taylor, the 18-year-old high school senior, was humming something along with his headphones as he started to get undressed in the locker room. The air was thick with steam, he'd been one of the last guys off the field, so he was getting in at the tail end of the showers. The young athletic mustang peeled off his jersey and he tossed it on the bench in front of his locker. His brown chestnut fur glistened from sweat, he kept it short in the summer, but it still hot far to hot. Next, he kicked off his shoes and wiggled out of his pants. His whole bottom half felt extra hot today for some reason, and his chest kept having odd twinges. He was starting to wonder if he'd pulled something during practice. The young stallion was just in his bright yellow jockstrap as he sorted through his locker looking for his shampoo and soap he'd brought from home, when he saw a shadow in the corner of his eye.

He glanced back, and he saw his friend Toby, a big polar bear who was a year older than him, standing behind him. He popped out one of his ear buds, and he waved at him, not bothering to stand up from his bent over position as he continued to look for his stuff.

"Hey dude, what's up?" He asked.

Toby didn't respond right away, he was breathing heavy, and there was a deep growl that rumbled in his chest.

"D-do you smell that?" The polar bear asked.

Taylor stopped and took a sniff of the air, it smelled like rank jocks like always. "No, what does it smell like?"

"It's... it's the most amazing thing I've ever smelt. It's like salmon, honey, and wildflowers all mixed together." The bear said with a moan in his throat, and he huffed before he continued. "I... I need it."

"What?" The young stallion asked in confusion, he went to stand up, but before he could, he felt a paw grab the back of his head and slam him into the locker next to his. He whined out in pain, and he felt his world spinning as he felt the much larger critter's weight slam into his back. His eyes went wide and he started to panic as he felt something side between his unprotected cheeks.

"I need it... I need you... I need to make you mine..." The older boy growled as his cock slide between those perky brown furred cheeks.

The young stallion whinnied, and he tried to push back, but he was built for speed and not strength like the polar bear was. He felt jaws grab onto his shoulder and he cried out in pain as those teeth tore at his skin.

"Toby... Toby, stop! Please, don't! We're... we're friends! You... you can't do this..." The colt whined.

His eyes went wide as he felt that cock head meet his pucker, and his body froze as he realized this was it, he was fucked, he was about to be fucked by that big thick polar bear dick and there was nothing he could do about it. His body went limp, and he sobbed against the cold metal locker door.

Taylor didn't hear the sound of rubberized horseshoes slamming against the tile floor or the hurried breath, but he did feel it as a whole water station's worth of ice water was thrown over himself and Toby. The polar bear backed off instantly, and he roared. His breathing went back to normal, and Toby spun around so his bare ass was facing the lockers. Toby looked confused, like he didn't realize how he'd gotten there.

"Go on, get!" The older stallion who had just rescued Taylor shouted.

"Coach Joe?" The polar bear asked in confusion. "What am I... what is that..."

"Go. Now." He growled.

"Yes Coach!" The boy said and he hurried towards his locker, he threw on some pants, and dashed out of the locker room.

Joe sighed and he grabbed a towel from a pile at the end of the lockers, and threw it over the shivering mustang in front of him.

"What... what just happened?" Taylor asked. "Why... why did Toby do that? He's not gay!" The young stallion whimpered.

"Take a seat, Taylor." Joe rubbed his forehead and gestured to the bench in front of him.

The younger horse did as his coach said and took a seat. He looked up at Joe, the large, impressive Clydesdale, and he felt a weird lump start to form in his throat before... he wasn't into guys, but he never realized how handsome the stallion was before. He had strong arms from his own sports days in high school and college, but the rest of him had softened. He had a nice thick belly that hung over his red basketball shorts, and he had a nice soft chest. The stallion put his hands on his hips, and he sighed as he looked down at the shivering colt in front of him.

"I'm not going to pussyfoot around it," the coach began, "you're a mareboi."

The young horse's eyes widened, and a scowl spread across his face. "What? No! I'm not some faggot that would take dick up their ass."

"You were about to," the stallion said and the boy in front of him deflated a bit. "Look. I smelled it at practice. I knew one of you must be going into heat. I thought it was Joseph, so I followed him to where he was meeting his girlfriend. But, once he was alone I realized the scent wasn't coming from him. You're lucky I got here when I did..."

"If... if that's true, why aren't you all over me then?" The young mustang asked, a pleading sound in his voice.

"Oh trust me... ever since I got close to you all I can think about is bending you over a bench and filling you with my foals. But I have training for situations like this, they've taught me how to override those baser instincts. It wouldn't look good if I knocked up every mareboi that stepped into my locker room," Joe explained.

The mustang shivered, tears starting to form in the corner of his eyes, and he pulled the towel tighter around him. "But... but... I'm a stallion..." The boy said. Joe stepped closer and he put a hand on the boy's shoulder.

"I know it's tough... But it's all very natural, there are just some boys... who chance decided needed to play mare for stallions or studs. Dogs have their bitchboys, bulls have their cowboys, etc. Don't feel bad kiddo," the stallion said trying to comfort the lad.

"What... what's going to happen to me now?" Taylor asked.

Joe took a seat next to Taylor so he could turn to face him. "Well... you're going to need to leave the team. We can't trust the other boys around you when you're in heat."

"But... but," Taylor started, "this is all I have! That's not fair!"

Joe put a hand on the boy's shoulder and gave it a squeeze. "I know colt, but those are the rules. We tried to go around them a few years back, and it ended up with a mareboi getting spit roasted on the field. When you work out or do too much activity, those pheromones you're making now just go into overdrive. It's for your safety. I have some pamphlets back in my office, let me get you those and let's get you home."

The young stallion nodded, and numbly got dressed and followed the coach.

"So you might be a mareboi!

A small portion of the male population are obtain the ability to carry young. This usually happens when they reach 18 or their early 20s, and their uterus begins to form. It seems to be a magical process, something residual magic of a spell left over from earlier days, after a great plague caused a need to rapidly increase the population. This is undetectable until it happens, and most boys are unaware they've been given this gift until they enter their first heat, and they start releasing pheromones. They become irresistible to other males, and are often..."

Taylor tossed the pamphlet onto his desk, and he curled into a ball on his bed. He couldn't read it again. Reading it made the whole thing too real. He'd glanced at the diagrams inside of how his insides must look now, and how he'd look if he was pregnant, but he tried to push those thoughts out of his mind.

The colt grabbed his body pillow and he curled around it. He was stripped down to just his jockstrap, he'd felt way too hot with his pants on, but he didn't want to be completely bare. He glanced back to make sure his door was locked, and he buried his head into his pillow. This couldn't be true. There was no way he was a mareboi. He was a stallion; he'd had lots of girlfriends... he wasn't some faggot. His mind wondered back to Toby. The bear must have just been some kind of rapist, that has to be the answer. He'd always seemed like a cool guy, but maybe he had just always been wrong about him.

Taylor shuddered as he thought about what might have happened if Coach Joe hadn't stepped in. He pictured himself being slammed further against those lockers, the bear's belly resting in the small of his back as that thick cock slowly slid into his warm hole. How he would have shuddered as those hips slapped against his round firm ass.

Without realizing it he'd started to hump against his body pillow imagining what would have happened. He huffed as he thought about the fangs of that bear biting into his neck, whispering for him to be quiet unless he wanted someone to hear. He ran a hand down his side and squeezed his ass, pretending it was the polar bear doing it, he humped a little harder, panting. He found himself mindlessly drifting his fingers between the cleft of his rump and tracing a finger around his glistening punk hole. He shuddered and before he could stop himself he was pressing his finger inside. It sank in, and it was warm and wet. He rocked his fingers in and out picturing it as the bear's cock.

His horny teenage mind finally caught up with what he was doing, and his heart lurched as he realized that his rump was slick with something... he... he was wet. He was wet like a girl. He pulled the fingers from himself, and the flood gates broke. The whole day slammed into him and he started to sob into the pillow, until he fell asleep.

Tap, tap, tap.

"Wha..." the colt said groggily.

Tap, tap, tap, came from the window again.

Taylor's head lifted from his pillow and he glanced to his window. He saw a shadow moving behind the curtain, and his face lit up.

"David!" He said happily as he jumped out of bed. He grabbed a pair of basketball shorts from his floor and slid them on, before heading over to the window. He flung open the curtain, and a doberman stood in front of his window smiling. The horse opened the window and the dog climbed in. He was wearing a tanktop that clung to his muscular frame that had some heft to it, he was a heavy weight for the school's wrestling team, and the coach made sure he kept on a few extra pounds.

"Dude, you okay?" The doberman asked. "I've been blowing up your phone, you never showed up for the party last night."

"Oh... uh, yeah," Taylor said. After what happened yesterday, he'd forgotten all about the Rebeca's birthday party. "I was just pretty zonked after practice on Friday, so I just came home and passed out." The young mustang started, he started to look around for a shirt that was semi-clean and then he spied his Xbox.

"Oh! Didn't the new Fortnite patch drop last night? We could try it out if you...." He trailed off as his eyes came back to his friend. He saw the dog sniffing the air, and a perplexed look on his canine face.

"David?" Taylor asked with concern in his voice.

"What..." the dog started, "is that smell?" The dog sniffed the air, and took a step closer to the young colt who took a step back. "It's like steak mixed with new tennis balls... it's... it's amazing." The dog said, drool starting to come from how jowls.

"I..." Taylor started, "I don't know. Hey... uh, I'm not feeling well. I think you should go."

"It's so strong... you have to smell it dude," the dog said either ignoring what Taylor had just said or not hearing it, the colt couldn't tell. "Wait... is it coming from you?" The doberman asked. He sprinted forward and grabbed Taylor by the wrist. He pulled him in close and pressed his nose into the other boy's neck and breathed in deep. "Holy shit, it is you."

"David! Let go," Taylor said softly, panic in his voice, not wanting his mom to hear, but wanting the other boy to get off.

"Fuck, I never noticed how good you smelled... where..." the boy said sniffing a little lower, "is it coming from..." He threw the other boy onto the ground and he held him down with a strong hand as he sniffed across the boy's chest and down to his shorts. He flipped Taylor over, the wrestling champ having no problem flipping the thinner horse, and his nose pressed to the other boy's rump.

"God dammit... I... I need it..." The dog growled.

"David, no, stop!" The colt shouted now, some panic in his voice. His heart pounded in his chest, and he felt the other boy start to pull down his shorts. He could feel the cold air of his room tickling his firm cheeks, and he started to cry. He felt a cold nose slid along his cheeks and his eyes darted around the room as he finally landed on a crutch he had stuffed under his bed from when he sprained his ankle last year. He grabbed it and he twisted his body around and cracked David across the head. The dog howled at the top of his lungs, and he looked confused.

"How did I... Where am... why are your pants..." he asked utterly confused.

Tears were rolling down Taylor's cheeks. He hated the way David was looking at him, he looked so lost and hurt, and he'd done that. His weird body had done that to his friend. He pulled up his shorts, grabbed his cell phone off his desk, and finally grabbed a sweat stained tank top from a spot next to his floor. He burst out of his room, his bare hooves slamming against the floor as he tore from his house, he vaguely heard his mom asking him what was wrong as he burst through the front door and his bare hooves slammed against the sidewalk as he sped away...

===

One week later.

Taylor looked at the cocktail of drugs in the pill container in front of him. He could barely remember what each of them did, the doctor had explained on Monday when he skipped class and went. He was so glad he was 18 and didn't have to have his mom come with him. He still hadn't told her what was going on with him yet.

He felt so... weird. The pills had been messing with his moods, the doctor had warned him that might happen. He vaguely remembered something about how they simulated pregnancy, so his body would dampen the pheromones that would drive other men crazy. He still had to be careful though, the doctor warned him about physical contact or exercise where anyone could smell him. He'd started to isolate himself from any of his friends, he didn't want to think about what he'd done to David, or what anyone must be saying about him.

He looked at the rainbow of pills in his hand, and he snarled as he thought about how they made his stomach cramp, his muscle's sore, and his chest hurt. He thought about tossing them in the trash, but he forced himself to take them. They tasted bitter on his tongue, but he swallowed them down.

He entered a haze after that, he felt like someone else watching his life go by as he got dressed, drove to school, and went through his classes. He could barely understand what his teachers were saying, they all sounded like they were just making noises as he doodled in his notebook. Finally, lunch came, and he found a table in the way back, away from where anyone he knew sat, and he started to eat. He'd felt like he was starving all the time now, he was sure he'd gained a few pounds, but he found it hard to care. His life was shit, so what if he was fat too?

He didn't notice the doberman walk up to his table, but he looked up when he heard a hesitant throat clearing. His heart sank in his chest as he saw David standing there, he could still see the mark where he'd slammed the crutch across the side of his face. The Doberman's right eye was still a little bloodshot, and there was a line of stitches across a cut.

"Look, Taylor..." The dog started.

The mustang's stomach twisted into knots. Was he about to tell him he hated him? Was he about to tell him that he never wanted to see him again? Was he about to say his dad was suing him for assault?

"I'm sorry," the dog finally sputtered out, "I... I don't know what happened. I remember doing that... stuff to you, but I don't know why I did it. I'm so sorry, can you ever forgive me? Will you come back to our table?"

Relief washed over the young horse. He hadn't expected that. He'd gone over this conversation again and again for the last week, but it never turned out like that. He smiled for the first time in days, he grabbed his tray and stood up.

"Don't worry about it dude... I'm sorry too, you sorta freaked me out. I shouldn't have hit you that hard," he said.

"No dude, you did the right thing. Whatever was wrong with me, it snapped me out of it," he said with a smile.

"About that... I should probably let you know why you were acting that way," the mustang started. He went to start explaining his condition and then he noticed that David was staring at his chest. He cocked his head to the side and asked, "what's wrong?"

"Dude, your chest is leaking," David said.

"What?" The young stallion asked in confusion and then he looked down. His eyes went wide as he saw that his chest was wet. He sniffed the air and he could pick out the scent of milk. He... he was leaking milk from his nipples. He'd soaked the front of his shirt with his own breastmillk. "No, no, no, no!" He wailed, and he threw his tray down and crossed his arms over his chest. Tears started to roll down his cheeks as he ran from the lunch room.

He ran to the closest place he could think of. The lockeroom. He ran up to the sink and ripped off his shirt. He grabbed his chest and squeezed, horror crossing his face as he saw milk dribble across his fingers. His chest had seemed bigger the last day or two, but... but he thought that was in his head. He stumbled backward until his back hit one of the rows of lockers. He sank to his knees, and started to sob into his milk stained fingers.

Taylor felt a hand on his shoulder and it gave a gentle squeeze. The boy sniffled, and looked up to see the Clydesdale, coach Joe, looking down at him with a sympathetic smile on his face.

"Rough day?" He asked.

"I... I started to leak in the lunchroom, all my friends saw I was soaked through my shirt..." The young mustang said as he dipped his head and looked away from the older horse.

"Hey that's nothing to be ashamed of, colt. It's just what your body is supposed to do, you're a mareboi, you should be proud of that. It'll take some time, but you'll learn how to be on the meds," the stallion said trying to comfort him.

"I... I don't want to get used to them, they make me feel weird... I... I just want to go back to normal, I miss my friends, I miss practice, I miss not having to worry about friends trying to rape me," the colt said, his lip quivering as he started to cry again. He went to stand up, but he found himself pulled against the older stallion's chest in a tight hug.

"I know colt, just let it out. There's no one to here to see, you don't have to be a big man, just let it flow," the stallion said.

Taylor pushed against him for a second, trying to get out of the hug, but he found himself hugging onto the older stallion tight. He started to cry as he squeezed him tight, he cried harder than he had in days, he wailed into that older stallion's chest, letting every ounce of sorrow spill out of him. He wasn't sure how long they stood there, but eventually the stallion had taken a seat on the bench and held the colt on his lap as he slowly stroked the back of his head. Coach Joe laid his head between the younger colt's ears and nuzzled them as he heard the sobs start to fade.

"Better?" The older Clydesdale asked.

He felt a nod against his chest. He stroked along the younger horse's bare back. The colt pulled back a bit, and he sniffled. He looked a little worried as he looked at the stallion's shirt that was stained with tears and milk. "Oh no, I'm sorry."

The stallion looked down and shrugged, "ain't no thing, colt. Happens all the time." The horse said as he grabbed his shirt and yanked it off, leaving his bare belly to press against the smaller horse's own.

"You have boy's cry and leak breast milk on you?" The younger boy said with a small smile.

"Oh my, we're already up to jokes! You must be feeling better," the stallion teased. "But yes, I do. I have two marebois like you at home. I'm used to being splashed with milk, they're both very productive. As for tears, only happy ones like when one of our sons was born." The stallion said as he slowly stroked up and down the younger horse's back, keeping him close and letting him feel safe and warm.

"Gosh, how do you not go crazy being around their pheromones all the time?" The colt asked.

"Well, it's not something we have to worry about. I keep them knocked up, and when a mareboi is pregnant, the pheromones just go away," the colt pulled back and his eyes were wide as he looked into the eyes of the much larger horse.

"You mean... they don't have to take pills or anything? They're just normal again?" The young mustang asked.

"Well," the older stallion started, looking a little hesitant, "I wouldn't say normal... did, did the doctor explain to you what would happen if you were knocked up?"

The colt shook his head, "He just told me what would happen if I didn't take the pills."

"Figures," the stallion said with an eye roll, "I don't know what the technical term for it is, but what I've always heard it called is "cunting". See... once you're bred for the first time, your body starts to undergo a change. You lose muscle mass, height, and your features soften. You'll grow breasts, though, that usually happens even with the pills. And your balls start to shrink... your dick too, one of my boys can't even get hard anymore, it just stays limp like a little clitty. You're basically gelded... your body stops producing sperm and focuses solely on being a new dam for your stud. There are a lot of marebois who become stallions, but if you get knocked up, that won't ever happen."

"Why does anyone do it then?" The boy asked.

"Well, my marebois tell me they enjoy getting fucked just as much as they enjoyed breeding... More so in fact, the one who can't get hard cums just from me fucking him all the time, he always spews his load when I'm hilted inside of him," the other stallion slid his hand down and slipped it onto the boy's rump, "You have more nerve endings in here now, your body in designed to enjoy cock."

Taylor bit his lower lip, and he shuddered at the touch. It did feel good... he'd played with his rump a few times over the past week, and he had to admit it felt good... he was always so wet too, his fingers always just seemed to slide in.

"Ugh... it'd be worth it... I... I'm tired of feeling like a freak, if I was knocked up, at least then my life could go back to normal for a while," he said.

"Until you had to take care of a colt of your own," the stallion said.

"I... I did always want to be a dad, I figured a mare would be involved in that, I just didn't think I would be the one to play that role," the colt admitted.

Joe continued to stroke the younger boy's rump, and his nostrils flared. Taylor felt something stiffen against him, and he gulped as he realized it was the older stallion's shaft.

"Well... you graduate in 3 months, right?" The stallion said, his hands starting to linger a little longer in places.

"Yeah, why?" Taylor asked.

"Well," Joe started, "I have a solution... Three months wouldn't be a long time, and you wouldn't start to really show until this summer. No one would know if you were knocked up." The Clydesdale cupped the colt's face in his hand, and he rubbed his cheek with his thumb. "You could join my herd. You could be one of my marebois. We'd take care of you and our foal." The stallion leaned forward, letting his nose touch the younger male's. "You wouldn't need to worry about college, finding a mare of your own, or any of that. You'd just have to worry about the kids, and taking care of me and the house. You could do whatever you wanted. Be whoever you wanted. It just costs you your manhood, would you do that? Would you become mine?"

Taylor's cheeks flushed, and he gulped. He... he hadn't expected today to go like this. Taylor pushed off of Coach Joe, he stood in front of him for a moment, his eyes going to the door before going back to the stallion sitting on the bench before him. He bit his lower lip, and he felt his cock throbbing in his jeans. Before he could second guess himself, he undid his jeans, and pushed them down. He was just in his jock now, the outline of his shaft against the bright yellow fabric, he slipped his thumbs under the black elastic, and was about to take it off when the older stallion stopped him.

"Keep it on, you should get used to not using it," he said matter-of-factly.

The older stallion joined him, taking off his shorts and showing that he wore nothing underneath. The shorts pooled around one of his hooves as his thick stallion cock throbbed in the air with anticipation.

Taylor huffed, his chest sore, and his dick throbbing with need behind his jock. But there was another need in him, one that had been clawing at the back of his mind for days but being naked in front of this stallion was now slamming hard against the front of his thoughts. He had a need to be filled. He'd always been straight, but now.... Now all he could think about was having a big cock in him just like that. Coach Joe held out his hand, and smiled confidently at the young smaller mustang.

Taylor reached out and took the older man's hand. The Clydesdale pulled him into his chest again, pressing his bare body against the much younger stallions's. The boy's bulging jock rubbed against the soft beer gut of the stallion's, and he shuddered as he felt that long thick stallionhood lay across his ass. Coach Joe's hands slid down the younger man's body, cupping his firm ass in his hands, and giving it a squeeze, before he spread those cheeks and let one of his fingers trace around that glistening hole. The boy shuddered, and he gasped when he felt that finger slip inside of him, penetrating his pink pucker. It slid in with ease, and he cried out in extasy as he felt his prostate nudged- a wave of pleasure unlike anything before washing over him.

"Nice and wet, you're born to be a mare, boy." The coach mumbled as he slowly worked his finger in and out of that slick hole. The stallion's cock nudged against one of those firm rump cheeks, and he rolled his hips. He leaned in and nibbled at the boy's neck, making him gasp above him.

"Are you sure you want this, boy? There's no going back. The second I cum inside you, you'll be cunted. Even if I pull out, your body will start to shrink those spud nuggets between your legs, and you'll become a proper mareboi. You'll just have a little clitty between your legs that spews your important mareboi cum. Taking my dick seals your fate," the coach said lustfully as a final warning about what the boy was about to do.

"Fuck! Please, Coach! Make me your mare. Make me yours!" The boy panted.

The stallion smiled, "what my filly wants, he gets." The stallion said as he slipped his finger from that boy's ready hole. He guided the head of his cock to that opening in, and Taylor felt the pressure against his hole. The boy's eyes went wide and he moaned out as he felt the head pop inside of him. He squeezed onto the older stallion tight, and whimpered with need as that thick stallion cock was slid inside of him. Inch by inch gliding into him like he was meant for it, that precum mixing with the juices flowing inside of him and making a cocktail that would soon transform him into the mareboi he was always meant to be.

It felt amazing, every inch felt better than the last. His body seemed to know just what to do, how to relax to let that thick stallion cock slip inside of him. He threw his head back, his fingers gripping into the stallion's strong arms as every part of him felt like it was on fire with desire. He moaned, and he was shocked when he felt the stallion's nuts press against his rump and he realized the whole thing was now flexing inside of him. The stallion nibbled at his Adam's apple, suckling on it as he began to bounce the boy in his lap. That long thick cock sliding across his prostate making pre ooze from his cockhead and into his jock.

The stallion started to kiss his way across the colt's collarbone, and then across his chest, and finally to one of his nipples. The younger stallion gasped as he felt the stallion's tongue slide across that sensitive bit of flesh, and he shuddered when he felt the stallion start to suckle. He felt that warm milk start to flow from him, adding to the mixture of feelings his body was experiencing for the first time.

"Mmm," the stallion said as pulled back from that nipple and licked his lips, "the first milk is always the sweetest..." He said as he nuzzled at the younger colt's neck. "Alright, enough fun and games. Now that you're my mare, I need to give you a proper breeding."

"Wha?" Was all the horny teenager managed to say before he felt the older stallion stand up, and he was slammed onto his back on the bench. Suddenly that big stallion was over him, that gut pressing into his needy trapped cock. He whined as he felt that weight on him, his hooves wrapped around the older stallion's sides, and the stallion held onto him tight as he began to breed the boy like the stud he was. That thick cock slamming in and out of that horny young colt. The boy's eyes going wide, and a whinny of pure pleasure escaping his lips as that cock head started to flare and rake over that extra sensitive pleasure knot inside of him.

He leaned down and latched onto the colt's other breast and began to suckle again. Taylor whinnied and he reached up and ran his fingers through the stallion's mane, and his cock flexed with need behind the cloth of his jock. He felt something starting to build up inside of him, it was different from anything he'd felt before, it was like a slowly building cascade of pleasure. Something was battering against his senses, like water building up behind a dam. He leaned his head back and he whinnied loudly and that dam broke. He thrusted forward as his ass began to spasm around that older man's cock. Cum started to pump into his jock. It was thicker and stickier than he'd ever shot in his life, it came and came and came as his body tried its hardest to get rid of every ounce of juice that made him male.

The stallion above him pulled back from his breast, milk still on his lips as his face contorted in pleasure. "Yeah, that's a good mare. Cum for your stallion. Here it comes boy, I hope you're ready to be a mama!" The stallion roared, his fat balls started to pull up, and then with a loud whinny he started to cum, pumping his potent seed deep inside of his new fertile mareboi...
