“Kristine? Sophie here. Listen, things are kinda falling apart on my end. My sitter called in sick and I can't find anyone else on short notice." Sophie said over the phone, her voice fully conveying the white mare's frazzled state.

“OK, calm down. Have you been taking your temperature?" the voice on the other end replied, calm and in control.

“Yes, and I'm definitely at my peak, but I just can't leave David alone…"

“Of course you can't. Tell you what, why don't you bring him along?"

“T-to your place? But what about…" Sophie blushed and her voice dropped to a conspiratorial whisper, in spite of the fact that her son was in school and there wasn't anyone else in the house.

“Don't worry, I got Luke a gaming room for his last birthday. If it can occupy so much of a grown man's attention it will definitely keep a twelve year old boy busy while we carry on as planned. You two can even spend the night if you feel too tired afterward." Kristine finished.

“I don't know. Maybe we should just reschedule?"

“Do you want to reschedule?" the human woman asked, her lip curling in a small smile, confident in what the mare's answer will be.

“*sigh* No…" Sophie replied. She had been looking forward to this night for some time now, and she knew waiting for her cycle to peak again would drive her nuts.

“Good girl. See you at eight o'clock." Kristine said before hanging up.

Sophie let out an exasperated sigh, always amazed at the way Kristine could get her to do almost anything, even when they weren't in character. If Kristine had suggested they postpone tonight, Sophie knew she would have went along with it. Well, it was a date now. And as long as she could keep David from learning what his mommy really did at 'book club', everything would be fine.

Standing around in her bedroom she turned to look at herself in the mirror. She'd been doing her yoga when the babysitter had called and she couldn't help but admire the statuesque mare looking back at her. She was close to thirty but had the body of a woman just leaving her teens, and nobody looking at her would believe she had a child. In truth, she'd been a pretty skinny filly, so instead of losing the baby weight, she just focused on toning her body, leaving her with C-cup breasts that rode high on her chest, a slim waist, and long shapely legs culminating in a round but firm ass.

“I'm gonna miss you…" she said, looking down at her perfectly flat tummy. After tonight, she wouldn't see it for at least nine months. Still, she was very much looking forward to the evening, as evidenced by a small damp patch in the crotch of her yoga pants.

She had met Kristine and Luke about two years ago when she responded to a personal add on a very specific message board. The married couple, a woman and a stallion, were looking for a mare to join them in a bit of… horseplay. Sophie had an interest in bondage and pet-play since she was a teen, and since she was a single mother with little time to date she watched and read quite a lot of porn, which turned that interest into a bit of an obsession. So after a few video calls arrangements were made and the mare had gone to her first 'book club'.

It had been, well, not love at first sight, but they had certainly hit it off. They had all agreed they'd spend an evening together getting to know each other, with maybe a bit of foreplay if things went well, but it had ended with the three of them in a sweaty heap, with her pussy leaking Luke's cum and her muzzle covered in Kristine's juices. After everyone present agreed there was definite chemistry, they agreed to make this a regular thing. As they were saying their goodbyes, Kristine had discreetly slipped Sophie an envelope, explaining it was a token of her gratitude in a voice that wouldn't take no for an answer. When she got home and opened it, the mare was shocked to find five hundred dollars inside.

It wasn't that it made her feel cheap (it actually made her feel a bit pricey), but it made her wonder if the night had been a wild hookup or if she'd unwittingly prostituted herself. Even though she was a single mother, and had gotten pregnant while in her senior year by a married man, the father of her child had been decent enough to provide them with enough money that she could finish school and even graduate from community college. She now had a good job at the local bank, and a cozy house in a nice neighborhood. In short, she'd never even considered becoming a sex worker, but here she was with five Benjamins after a night of wild sex. Great sex, actually, and after quite a long dry spell…

When Kristine called her a few days later to arrange another get-together, she'd accepted politely, but as she walked up to the door she was determined to set the older woman straight on a few matters. She had a whole speech in her head, with quite a few terse words thrown in, but when Kristine opened the door it seemed to evaporate. The woman had a natural, sensuous charisma, and exuded confidence, so when she greeted the mare as a friend she couldn't help but want to be one.

She told Sophie that Luke was in the shower and would join them shortly and offered her a drink. As they sat down to chat, the mare did manage to bring up the envelope. Kristine had explained she meant what she said when she gave it to her, that it was meant as a thank you with no strings attached, and certainly no expectations on her part. She explained she made her fortune early in her life when some speculative real estate investments paid off in spades (something Sophie had surmised since her house was in a very nice part of town) and was now semi-retired. She didn't live an extravagant life, preferring to spend her money on things and people that brought her… joy.

Sophie thought about saying something, maybe thanking Kristine but politely declining any future gratuities, but at that moment Luke walked in stark naked, his mane still damp from the shower, and neither woman felt like continuing the conversation. Several hours later, after they've drained Luke and cleaned each other up the two females said their goodbyes and Sophie found another envelope pressed into her hand.

It didn't really bother her anymore, since over time she realized Kristine was really over-generous when it came to spending money on her guilty little pleasure. It became evident when she started splurging on gear for their little sessions, starting with tailored leather accessories (tack and harnesses for her and Luke, and crops and riding boots for herself), followed by various bits of BDSM accessories and furniture and culminating in the basement being decorated to look like a stable.

The kinkier their nights together got, the stronger the bond between the three became, to the point that Sophie no longer even considered dating guys. She knew regular sex couldn't compare to the nights with people who shared her deepest fantasies. Why should she just sleep with a man, when she could get strapped down and rutted by a stallion, or clean her mistress after she's finished riding him? How would she explain to her date that she loved the smell of straw mixed with sweat, that she needed to feel a bridle rubbing against her face? That the smack of a crop turned her on and that she shivered with delight when a bit was fitted into her mouth?

Their nights together meant a lot to Sophie, but that wasn't the reason tonight couldn't be rescheduled. A couple of months ago, Kristine had approached her with a different proposition. She had wanted a child for some time now, and wanted Luke to be the father. Since her being human meant they couldn't conceive, she had hoped Sophie might agree to bear his foal. The offer, delivered in Kristine's usual straight-forward tone, had stunned the mare into silence while she contemplated the proposal. But even as she thought it over, she felt the answer was already there, and that she was just finding a way to rationalize it. Kristine must have suspected what it would be, especially since Sophie's favorite scenario included her mistress bringing out a stallion to breed her.

But it was more than a kink. The three of them had become close friends, and Sophie had opened up to them in ways she never had with anyone else. Having a baby was no small thing, but she realized she truly wanted to do this for them, and proceeded to tell Kristine so. She was surprised when the woman got up, and without uttering a word bent over her and threw her arms around the taller mare, her usually dominant posture temporarily forgotten as she hugged Sophie tightly. Oh well, everyone's allowed to be a softy once in a while the mare thought as she hugged Kristine back. After they were done Luke was called in and told the good news and soon after the three went to the 'stable' for a sort of practice session.

After that came the medical examination, and unsurprisingly the doctor told Sophie she was in excellent shape and could go off the pill. Then they signed the necessary papers – Sophie agreeing to give Luke and Kristine custody of the baby, and the two agreeing to cover all medical costs. She knew it would be hard to give up the baby, but since the two could hardly pretend the foal was biologically theirs, they agreed to let the child know early on that it spent nine months living in Aunty Sophie's tummy (omitting the details about how she got there).

When she got to the part that covered surrogate compensation, Sophie almost protested, but Kristine told her firmly that doing this for free was out of the question. She almost pushed the point, futile as it may be, but when she saw the actual number she was struck mute. The money would be enough to put David through college, and that thought made it impossible for Sophie to turn it down.

The aforementioned colt was currently sitting next to her in the car, still a bit sullen that his insistence that he was old enough to be left at home alone was met with a firm 'no'. He dreaded what he thought would be a mind-numbingly boring evening – adults sitting around discussing books that didn't even feature dragons, pirates or spaceships! It was only the promise that he'd be left alone to play video games that made him grudgingly agree.

Once they arrived David was introduced to Kristine and Luke and promptly showed to the game room. The colt's eyes went wide when he saw it, the dark interior lit by dimmed LED strips along the ceiling, two comfy looking beanbags parked in front of a massive TV, and a coffee table with enough snacks and soda to last for days. He was dimly aware of his mother telling him they'd be downstairs as he sat down and waited for the console to boot up.

Once the adults were satisfied the colt's attention was preoccupied, they made their way to the basement. The door was closed and clothes were impatiently stripped and more appropriate attire was put on. Soon Sophie was standing naked except for her harness, a network of narrow leather strips that started with a collar around her throat and ended with a strip of leather that was even now rubbing against her pussy. Luke's harness was much simpler, consisting of broad leather straps that went around his shoulders and across his back and chest, the black strips contrasting nicely with the palomino's creamy coat and white mane. Once both equines had their bridle's on Kristine sauntered over to them, a long leather lead dangling from each hand. Even though she was smaller even than Sophie, let alone her stallion husband, the human woman was unmistakably the dominant figure, her russet hair tied back in a bun, the cupless corset hugging her waist exposing both her pussy and her B-cup breasts, and while her riding boots were impractical due to the fact they went past her knees, they served to complete the stable-mistress look.

The leads were clipped to each equine, but only Sophie was lead to the center of the stable, after Kristine had tied Luke's lead around a nearby post. This was the way it usually went during their playdates, Kristine preferring to give her stallion a nice show to get him worked up before he was allowed to join in. The domme lead her mare to the center of the room, turning her towards a small camera on a tripod.

“Now, my little mare, would you introduce yourself?" Kristine asked sweetly from behind the camera.

“Hi, my name is Sophie." The mare replied with a demure smile.

“And why are you here, Sophie?"

“I'm in heat and my mistress brought me here to be bred by her stallion." Sophie said, feeling color rise to her cheeks. They had made videos like this before (they helped get her through the week) but it felt different knowing that this time she was almost sure to leave with a foal in her belly. Although she loved David and never regretted having him, the truth was that he was a bit of an accident. This time Sophie knew he would be letting a stallion mount her when she was at her most fertile, and the knowledge made her both anxious and horny. That meant she looked every bit the skittish mare in heat and one look at her mistress' face told her just how much she was enjoying the sight of her in this state.

“Then let's get you ready." She said, stepping forward and leading the mare to a short padded bench it the center of the room, it's legs adjusted so it reached Sophie's waist.

“Put your hands on the bench and let's have a look at you." Kristine said, more for the camera's benefit, since Sophie knew the routine. She put her hands on the soft leather surface, bowed her head, spread her legs, arched her back and lifted her tail. The camera would get a side-view of the action, but she knew that in this position the stallion behind her was getting a real eyeful.

“Good girl…" Kristine purred as she unbuckled the strap covering the mare's privates. As the leather slipped away and the cold air hit her lips, Sophie realized just how wet she'd gotten before they'd even started.

“Mmm, eager little thing." The domme behind her husked as she raised her tail even higher, making sure Luke got a good view. Sophie felt the grip on her tail tighten as Kristine started to wind the pink vet wrap around it until she'd covered it a third of the way.

The mare felt Kristine's fingers trail down her white rump and shivered when they settled on her moist pink slit. The woman slipped two digit's inside the eager mare, delighting in the needy little noise she made. Sophie prepared herself mentally for the next part. Kristine had the longest, most skilled fingers the mare had ever seen, or more to the point – felt, and a sadistic streak when it came to using them. She knew that for the next few minutes her mistress would keep bringing her to the very edge of orgasm, but never giving her release, teasing her over and over until she was a dripping, panting mess.

She whined and whimpered as the other woman's fingers curled and flexed inside her, hitting all the right spots but not lingering long enough to make the mare cum. She felt a third finger slip in and tried to clench her sex, to get just a bit more stimulation, even though she knew it was no use. Whenever Kristine would see the telltale signs of her climax, she would hold her hand still, delighting in her mare's desperate noises. She slipped her pinky in and a short while later started sliding her entire hand between the mare's flushed lips.

Sophie bit her lip and gripped the edges of the bench as she felt her quim spread even wider. The penetration was far from painful, the honey her pussy was drooling making it even easier, but it was agonizingly slow. The feel of her muff slowly swallowing Kristine's hand had her panting with lust, her eyes glazed as every bit of her attention was turned to the sensations coming from her rear. She let out a gasp as the widest point slipped inside her and her lips clenched around the woman's wrist.

Kristine held her hand in the quivering mare, not wanting to push her over the edge. Instead she ran her other hand along Sophie's lower back, scratching the base of her tail and smiling as she raised it even higher. Still, she was also quite eager to get to the next part, although she didn't let it show. She pulled out of the mare, savoring the gasp she let out when her pussy was left empty, as well as the sight of the slightly gaped pink lips. She walked around the bench and stood in front of Sophie. With her mouth hanging open, her tongue lolling a bit and her eyes lidded, she really looked like a mare in heat, desperate for a breeding.

“Good girl. Now clean your mistress." She said, extending her hand until it was inches away from the mare's milky white muzzle. Without a second's hesitation, Sophie ran her long equine tongue over the proffered hand, looking up at her mistress while she licked up her own juices. Once Kristine was satisfied she took hold of Sophie's bridle and gently but firmly pulled her head up.

“Open wide." She said, the mare instantly complying. When her mistress put the rubber 'bit' in her mouth she bit down on it while Kristine clipped the straps holding it to the bridle, holding the length of hard rubber securely until her domme allowed her to use her mouth. Sophie shivered, enjoying this little ritual that turned her into her mistress' favorite little mare, to be ridden or bred according to her whims.

Kristine admired her handiwork for a few more seconds before sauntering over to a table that held a few more toys they'd be using tonight. Sophie had a good idea of what was next, but her pucker still clenched when the older woman turned around holding a bottle of lube and a black butt-plug. It wasn't the size of the toy that made the mare anxious (she'd taken Luke under her tail on several occasions) but rather what was inside of it. Buried in that matte black silicone was the strongest vibrator the mare had ever felt. Kristine called it 'The Spur' and used it much the same way. Her riding crop had a button on the base, and every time she pressed it the toy buried in her (or sometimes Luke's) ass would give a short but incredibly intense burst, literally spurring whichever equine it was nestled in.

She heard the woman behind her pump up a spurt of the clear goo a second before it was gently smeared all over her pucker. She relaxed and took a deep breath as her mistress pushed her finger under the mare's tail, rubbing the lube inside her. A few seconds later the finger withdrew and Sophie felt something cold and firm press against her opening. She groaned as the toy penetrated her, Kristine applying slow but steady pressure, forcing her to stretch around the plug. Once the widest part was inside, her pucker clenched around the slim base and she could feel the stopper rubbing against her tail-hole. She took a few deep breaths, enjoying the sensation of fullness before she felt Kristine's hand on her back, pushing her down on the bench.

The mare obediently got into position, laying down on the short padded surface with her legs spread and her stuffed ass thrust out towards the snorting stallion behind her. The surface supported her weight (they'd learned early on that Sophie's legs tend to get a bit shaky during a long rutting) but ended just below her chest, giving her mistress unrestricted access to those perfect and oh-so-sensitive alabaster globes.

Anticipating Kristine's wishes, the mare crossed her hands behind her back, a tingle running down her spine as her mistress proceeded to tie them at the wrists with a leather strap. It wasn't really a restraint, the bindings being fairly loose and comfortable, but it gave Sophie the illusion of helplessness that she craved. She heard Kristine slowly walk behind her, her head looking forward but her long ears twisting to follow the sound of the woman's heels on the wooden floor. She let out a muffled gasp when she felt the cool leather of the riding crop run over her privates.

“My, my, what an eager little filly! I guess we won't be needing the spreader bar tonight?" she heard Kristine say and shook her head empathically. She was so horny and eager she had no intention of closing her legs until Luke's seed was planted deep inside her, providing she still had sensation in them by then. She felt the smack of the crop against one of her cheeks and squealed around the bit in her mouth.

“Now be a good little mare and show your stallion you are ready for him…" Kristine purred and the mare knew instantly what she meant. A real mare in heat would be winking, flashing her clit and squirting her juices to show the male she was ready to be bred. Not having the same anatomy back there as a feral mare Sophie knew she couldn't actually wink, but she'd learned a little trick early on in these sessions.

She arched her back and raised her tail as high as it could go, giving the two the best possible view of her rear before rhythmically clenching her kegel muscles and relaxing them after a couple of seconds. She'd practiced it in front of a mirror and knew it would push her lips out slightly, as well as force a bit of femcum from her pussy. The first time she did it Kristine was delighted, and it apparently stirred something deep inside Luke because that night he'd fucked her harder than ever before. This in turn motivated Sophie to wink at him ever since.

As she signaled her readiness she could feel her soaked pussy drooling honey, and could distinctly hear Luke's heavy breathing. This little show always teased the hell out of the young stallion, but he was well trained and never moved an inch or touched himself without his mistress' permission. The sounds of the Kristine's boots as she walked away filled Sophie's ears, and her own breathing became rapid when she heard the clacking of Luke's hooves.

From her position, she couldn't turn around to see him, forcing the mare to rely on her sense of sound, touch and even smell. She didn't mind, because it made the physical sensations a lot more intense. And after all, she'd have the whole week to admire the sight of the cream-colored stud plowing into her, in high-def video. She heard him snort just behind her a moment before he planted his strong hands on her round ass. She answered with a soft nicker, both of them firmly in their feral characters.

She felt the pokes and nudges of his shaft against her rear end, since like a true stallion he wasn't allowed to use his hands to guide himself in, relying instead on his mistress to help him penetrate his mare. On those nights when the 'spur' was in Luke, there was always the added thrill of not knowing which hole their mistress would chose, but tonight there was no doubt on anyone's mind where that equine rod would end up.

After a few more seconds of Luke's teasing jabs, she felt the blunt head pushed firmly between her lips, as Kristine guided her husband's cock to the eager mare's cunny. She forced herself to relax, but still gave a muffled scream as the entire shaft was driven inside her in one powerful stroke. Her eyes bulged and her mouth drooled as she felt her walls tighten around a foot of hot stallion flesh now throbbing inside her. She could feel Luke's hands, groping and kneading her ass while he held himself hilted in his filly. That possessive gesture told her that even though he often took her gently, with smooth, slow strokes, this wouldn't be one of those nights. Tonight wasn't going to be about sex, it was going to be about rutting – sharp, powerful thrusts, the stallions hips and thighs clenching to drive his shaft deep into the mare underneath him.

Still, he was considerate enough to give her some time to adjust to having him inside her, but a sharp burst from the vibrator in the mare's ass told them that their mistress was getting impatient. The stud behind her obediently began to buck, driving his cock in and out of his mare in fast, short strokes, his hips audibly smacking into her ass every time he hilted himself. Kristine had circled in front of the two, smiling as she theatrically dropped the stallion's lead, giving him free rein. She drank in the sight of the mating equines while she toyed with her crop, her finger sliding over the button on it's base that would send another maddening burst through their bodies. She then bent over and started toying with Sophie's breasts, gently squeezing the milky white orbs and tweaking their stiff pink nipples.

“Mmm, good girl. Just imagine – in a little while you'll have a beautiful little foal suckling on your pretty teats…" the woman husked in her mare's ear “…or maybe two. I've made Luke save up all week, and you are going to take every drop he pumps into you." She added with a mock-diabolical grin. After a few more tweaks she released Sophie's breasts, letting them dangle back and forth as the stallion bred her.

David decided it was time to take a break from gaming, especially since those two cans of soda he'd downed wanted out. He went to the living room to ask where the bathroom was, but was surprised when he didn't find any of the adults there. Fortunately he managed to find the bathroom on his own, but heard some strange sounds from the door opposite it when he was leaving. He presumed his mom and her friends were inside and figured he'd just quietly check in on them without interrupting. His eyes shot open wide and his jaw hit the floor as he saw the scene taking place in the basement.

From his vantage point he saw the back of the stallion as he strained and bucked, as well as Kristine, almost naked and talking to… Mom? He couldn't see her face, or even most of her body, but he recognized her snowy white fur. Then it dawned on him what the male horse was doing, and to whom. Unbeknownst to his mother, David had learned about sex a couple of months ago while he was at his friend's house for a sleepover and the boys managed to break through the parental lock on the computer.

It was also the first time the young colt had masturbated, and in the following months he'd touched himself every time he got the chance. He'd also noticed the sight of his mom sometimes got him stiff, especially when she was doing her yoga, but even though he saw her as beautiful he never fantasized about her, and the idea of sex with his mother repelled him. However, seeing his mother like this, bent over in front of the rutting stallion had gotten him hard almost instantly. He became worried for a second, wondering if his mother was trapped, if Luke's rough thrusts were hurting her, but looking at the way Kristine was talking to her, softly and calmly, bending over her to brush Sophie's mane from her face put him at ease. It dawned on him that this is probably what the three were doing every week and confirmed a long-time suspicion – nobody could be that excited about spending an evening talking about a book!

The colt's train of thought was interrupted when the woman in front of his mother raised her head, probably to face her husband, but David was almost certain she had seen him. He jumped away from the door and threw himself against the wall, covering his mouth to stifle his panting, startled by the thought of being caught peeping. He pricked his ear up and listened, but the noises the two equines were making remained unchanged, and there was no telltale sound of boots to indicate Kristine was moving toward the stairs. Satisfied that he'd managed to avoid discovery, he turned off the lights in the hallway and slowly made his way to the door, opening it a crack and carefully peeking inside. The adults seemed oblivious to his presence so he kept watching, his hand slowly reaching inside his pants…

*******

Unbeknownst to the young colt, Kristine had spotted him, but she realized the two rutting equines couldn't see him. Her face remained a mask of confidence while she pondered how to proceed. She had no intention of stopping the mating - there was something special and fragile in the air tonight, and she knew it would be gone forever if the two were interrupted or she left the room. Still, her motherly instincts had surfaced ever since Sophie had agreed to carry Luke's foal and she realized the boy might have been scared by what he saw, maybe even worried for his mother's safety. She got an idea how she might put David at ease without the two equines getting wise. Walking back to the prone mare, she gently removed the bit from her mouth.

“Enjoying yourself, my little filly?" she said in a voice clear enough to carry over the sounds of sex filling the room.

“*pant* Y-yes…" Sophie said, gulping air now that her mouth was free.

“It looks like my stud is getting awfully rough with you. Are you sure you don't want me to pull him off?" she asked, her lips curling slightly.

“N-No! Please –ahh!- mistress… I need…" the gasping mare pleaded desperately, her sentence broken by her stallion's thrusts. It did the trick – nobody hearing her could doubt she was a willing participant. Kristine also thought the expression on her face was priceless, and made a note of her reaction. After all, her mare was sure to need a bit of… discipline… sometime in the future, an apparently even threats of denial were very effective.

Speaking of which… she thought, reminded of her own needs. She decided not to replace the bit, instead putting the tip of her crop under the mare's chin and lifting her muzzle to her wet snatch. Ever eager to please her mistress, Sophie snaked her large tongue out, giving the glistening lips a few licks before plunging it in. Kristine rested her hands on the top of the mare's head, her fingers digging into that milky-white mane as a shiver ran through her. She loved the feeling of a broad, long equine tongue worming it's way around her love canal, but even though riding Luke's muzzle was fun, Sophie had a definite knack for getting her off.

Stealing a glance at the door she noticed that David was still peeping on them. He was smart enough to turn off the light in the hallway, but the dapple colt had inherited too much of his mother's coloration to blend into the shadows. Watching out of the corner of her eye, Kristine was sure she could also spot movement near his crotch. Dirty little boy! she thought but didn't feel she was in a position to judge, since she was riding his mother's muzzle while her husband thrust and humped in order to put a foal in her belly.

She turned her attention the stud horse in front of her, noticing his long mane was getting damp with sweat, every muscle taught as he tirelessly bred his mare with a stamina that would put an actual stallion to shame. Grabbing hold of his bridle she pulled his head towards her and kissed him deeply, letting him know what was in store for him once they were alone. She knew most people saw the young stallion as a sort of trophy husband, and although apart from some light modeling work Kristine did support him the two were deeply in love, which was the whole reason she wanted to be the mother of his child.

After a while the two broke their kiss, panting as they caught their breath. While they gazed lovingly into each other's eyes, Kristine's lips curved in a wicked smile as she pressed the button on her riding crop, sending another burst of vibration through the two equines, and bringing her stud's attention to the task at hand. The powerful vibration had been too much for Sophie, and the domme stroked her mane as she felt the mare squeal into her pussy as she rode out her orgasm.

Sophie must have thought the spur was meant for her, and Kristine soon felt herself climaxing under the mares redoubled efforts. She felt her pussy gush, the honey eagerly lapped up by that dexterous equine tongue, and after she'd been cleaned she bent down to plant a kiss on the mare's lips, tasting herself on her messy muzzle. Giving Sophie a scratch between her ears, she moved to the side of the two to get a better look.

Even though she'd just come, her breath was already quickening at the sight of Luke's mottled shaft, glistening with the horses' combined juices as it pistoned in and out of his mare's quim, the usually pink lips now a rosy-red after the pounding they've taken. Moving behind them she admired the sight of her stallion's rear, the straining muscles visible behind his tail as his hips bucked with every savage thrust he made. She reached out to cup Luke's swollen sack, marveling at the size and weight of it in her hands. Brushing up lightly against him, she brought her lips to a few inches of his ear.

“Breed her for me, stud!" she husked. At his mistress' insistence, the young stallion gave in to his instincts, grunting as he drove himself in with enough force to almost raise Sophie's hooves of the ground with each thrust. Kristine bit his ear lightly as she felt his sack leave her hand, ready to empty itself in the whimpering mare below him.

*******

Once Kristine was no longer in front of her, Sophie's face lost all focus, her eyes lidded and her jaw slack as all of her attention settled on that glorious shaft bottoming out inside her with every buck of the stallion's hips. The mare's head was swimming, her pussy feeling especially sensitive after her climax, her mistress' scent filling her nostrils while the wet sounds of their mating filled her ears.

She wasn't sure how long they'd been at it, or how much longer either she or Luke could last, but when she felt the stallion flaring inside her and slamming into her even harder, it was both too soon and not soon enough for her. She screamed with delight with every savage, feral thrust, until she finally felt Luke push in as deep as he could inside her, his crotch pressed against her pussy, his fingers digging into her hips, tail flagging as he released his seed directly into her womb.

Her breath caught in her throat when she felt the pulse travel through her stud's shaft and left her mouth in a feral whinny as she felt him spurt inside her, climaxing from the sensation of his seed flooding her, breeding her. Luke had cum inside her plenty of times before, but this was different – the knowledge that she was fertile while he was planting his seed in her pushed her, the mare cunt clamping around the cock and greedily milking it of every drop, the deluge of stallion spunk trapped inside her by that massive flare. She shivered, riding out the most powerful orgasm in her life while her stud did the same, panting as he ground his crotch against her lips.

*******

David was trying to catch his own breath, looking at the mess he made in his head while trying to process what he just saw. The sight of his mother bent over under the thrusting stallion was the sexiest sight he ever saw (although that wasn't saying much) and he'd climaxed shortly after the two did, biting his lower lip to stifle his boyish cries. He kept watching, eyes glued to the scene as the stallion slowly withdrew his now soft shaft, gasping as cum gushed out of his mom after the flare slipped out.

He saw Kristine reach out and rub the mare's messy privates, speaking too softly for him to understand before starting to undo the strap binding his mother's hands. Realizing the adult's would likely soon be getting dressed and making their way back up, he slipped into the bathroom to clean himself up before making his way back to the game room, secure in the knowledge that they hadn't seen him…
