Sarah waved Mr. and Mrs. Miller goodbye as the zebra couple drove off on their little weekend getaway. Getting away, that is, from their twins - Tommy and Toby, who they left in the young ewe's capable hands. At 17 she had a reputation as a dependable sitter, even with handfuls such as the two zebra colts who were even now arguing about what toppings to put on the pizza they were going to order. They always got pizza when Sarah babysat them and even though it wasn't a particularly healthy meal, when the kids stuffed themselves with all that dough and cheese it put them out better than Ritalin. Seemed to be more addictive, too. She'd scrounge up something for herself since Mrs. Miller left the fridge stocked with healthier food, something the twins would discover tomorrow.
Sarah wasn't vain but she did look after herself. She was a bit of a late bloomer and spent most of her teen years flat as board. In the past year or so she really filled out in all the right places and she wasn't eager to start filling out in the wrong ones. Her perky C-cup boobs were eye-catching even in the sensible blouse she was wearing, and her plaid skirt failed to conceal a firm, round butt.
Her curves were made more prominent by the fact she was almost completely shorn. She knew that some girls, especially in colder rural areas, liked to go 'natural' and floof up, but she always kept her coat short, and now that summer had started she trimmed twice a week. The only woolly parts on her were her head and the back of her neck, where the white curls were longer and more hair-like, a bushy white tail, four fluffy 'bracelets' on her wrists and ankles, and a little white heart at the top of her chest. The rest was a down so fine and short that her skin almost showed through made it look slightly pink.
After much deliberation the pie was ordered and devoured minutes after arriving. That seemed to calm the two zebra colts down and they all settled down to watch a movie, Tommy even being nice enough to bring over three glasses of ice tea, blushing slightly as he handed one to the reclining ewe so that she wouldn't have to sit up. The twins selected a movie featuring some superhero Sarah never even heard of but that seemed to excite the boys, who rarely agreed on anything. She sanctioned their choice, even though the movie was rated PG-13 and the twins were still twelve. As the plot unfolded the two colts' eyes were glued to the screen, while Sarah seemed to have trouble keeping hers open.
She drifted off and the movie blended into a dream - the spandex-clad dragon had just rescued her from the clutches of an evil villain and was flying through the night with the swooning ewe in his strong arms, whisking her to safety. After delivering her to some sort of secret base, the buff dragon proceeded to 'unmask' himself and Sarah's dream took a huge leap from PG-13 straight to X. She melted into his arms, and could almost feel herself being groped and squeezed all over. As her lurid fantasy spun out of control, the protagonist was revealed as being part tentacle monster, having sprouted a series of suggestive appendages. Sarah didn't seem to mind, even as some of the tentacles wrapped themselves around her wrists, lifting her up as other tendrils spread her shapely legs, allowing yet more lusty limbs to explore her supple body, leaving trails of goo as they did. The sensations seemed almost too real and Sarah felt herself start to groggily wake up, understandably reluctant to let the dream end just as it was getting to the good part.
"I think she's waking up." a voice too high pitched to belong to her masked molester made Sarah open her eyes, and it seemed that a part of her dream had followed her to reality, a black appendage dripping goo filling her field of vision.
"What...the...?" the confused ewe mumbled, her mind still fogy as she managed to focus on the shiny black zebra cock pointed at her face.
"What are you doing!?" she shouted at the cock's owner, one of the twins who now seemed slightly worried, but not actually scared. Sarah tried to sit up but found it impossible. Her arms were stretched out somewhere above her head and she couldn't move them an inch, and she couldn't seem to straighten out her legs.
"OK, promise you won't get mad?" the voice came from the other direction, and she saw the other culprit standing between her legs with his own erection and uttering the phrase she knew as a babysitter would precede an infuriating statement.
"I promise not to kill you." That was all she felt she could commit to, and it was quite a generous offer, in her opinion. As adrenaline brushed the cobwebs from her mind, she realized she was lying down on her back, the twins having folded the back of the couch to form a bed. Her hands were tied at the wrists, the other end of the rope no doubt tied to something, since she couldn't get them down. Her legs were folded, her ankles bound to her thighs and the colt between them was easily holding them open with one hand on each knee.
"Well, since you last babysat for us, we found some videos online with men and women sorta... playin' around and we wanted to try it with you, but we were worried you wouldn't wanna play, and it was Tommy's idea-"
"Hey, we said no telling!" the colt with his shaft an inch from her face piped up, apparently upset by this betrayal of his trust. Hurts, don't it? She thought bitterly.
"-to give you half of one of mom's sleeping pills, an' tie you up. We figured if we played with you while you were asleep, you'd get all hot and moany, and when you woke up you'd want to sex with us."
"Where the hell did you get that idea!?" she asked while trying to wriggle out of the ropes to no effect. Damn Boy Scouts!
"We made a post on a message board with some of those videos about how we were two teenagers who wanted to have sex with our babysitter and asked for advice on how to do it..."
Ah, that explains a lot.
"Wait, what do you mean by 'played with me'?" she asked, dreading the answer.
The twins looked sheepishly at her sheepish chest, and even though she couldn't crane her head to get a good look, she realized that her boobs were damp and there were streaks over her upper chest. She licked some goo of her lips, turning bright red after she realized what it was!
"Well, we kinda played with your boobies, and took turns rubbing our things between them until we cummed" Toby said.
"It's 'came' and the two of you are too young to be doing that, especially to someone you drugged and tied up! Now untie me and we can forget this happened, because I did NOT enjoy it and I'm not doing ANYTHING with you!" she told the boys, trying to stay cool with little success.
"You did too enjoy it! Look!" Tommy said, pushing a smartphone in her face. A video was playing, showing Toby straddling her tummy and pushing her boobs together as he rubbed his ebony shaft between them, the slightly flared head poking through as it occasionally spurted pre on her neck and chin. Tommy's shaft was visible now and again and it was obvious the boy was stroking it with one hand while filming with the other. And Sarah hated to admit it, but she really did seem to be enjoying it, her lips parted sensuously as her quiet moans mixed with the thrusting boy's, interrupted every now and again by Tommy whining that it was his turn now. How could she explain to the boys she wasn't enjoying what they were doing, without saying that she looked like she was enjoying it just because in her mind she was about to be ravished by Tentacleman? And would it, strictly speaking, be true?
The problem was Sarah had a little secret, in the form of a folder on her computer labeled 'Spreadsheets' that was almost 20 gigs in size and didn't contain a single spreadsheet. Instead it was a meticulous collection of artwork, fiction and animations, most of them in Japanese, that contained adult women in adult situations with very much non-adult boys. Well, some of them skipped the women. She knew those were kinky fantasies, and she never even dreamed of doing anything with a younger boy. When she babysat she always wore plain and proper clothing and never behaved even remotely sexually. But that was all to make sure she never stepped out of line. She'd never even imagined this scenario. The boys in her spreadsheet folder were always shy and timid! All that effort making sure I didn't become a predator, and I end up becoming the prey.
Her attention was back on the screen when Toby started grunting cutely as his young cock flared and sprayed his spunk over his sitter's chest and neck, a few spurts reaching her lips. He didn't have time to enjoy the afterglow since his brother was nudging him, insisting it was his turn now. Reluctantly he slid of the ewe and the room spun while the phone was handed over, focusing again on the near-identical Tommy now sliding his shaft along the mess her brother made.
"Alright look, it may have seemed like I was enjoying it, but you can never do something like that to someone who's asleep, or someone who says they don't want to do it. And I'm telling you now that I don't want to do anything like that with either of you." she said a little more calmly, realizing that her reactions, in spite of being involuntary, might have spurred the boys on.
"But if you didn't really like it, how come you're so wet down here?" Toby said, and Sarah let out a squeak as she felt the colt's fingers probe between her folds before he raised it back up, his fingers slick with her juices.
"See? It says on the internet girl's only get wet like this if they really want to have sex. And your nipples are stiff, and you're blushing!" the boy said triumphantly.
"I'm blushing..." Sarah began, trying to stay calm "...because this is embarrassing. My nipples are stiff because you stripped me naked and the cool air makes them do that. And my wetness... is none of your business!" she snapped after failing to come up with a way to explain that. Well, two out of three ain't bad. The truth is this was kinda turning her on. The boys were cute, and even though they were young they were still equines, each sporting a seven inch black shaft with a plump little sack beneath it. And watching those boys pump their young cocks between her rosy-white breasts, their little butt cheeks clenching every time they lunged did get her steamed up. 
"All right, tell you what - we'll start having sex, and if you really, really decide you don't like it, we'll stop, OK?" Toby said as he lined his immature rod with his sitter's quim.
"What? Don't you daAaahh!" Sarah cried out mid-sentence as the boy's flared head pushed past her lips and entered her. God, I must be really wet! she thought as her pussy clenched around the thick shaft. Her biggest boyfriend had been a buck, and even though his thing must have been 8" long, it was slim and pointed. Despite the easy entry, Toby's immature shaft was giving her a good stretching. Her ears flicked back and the colt gave out a cute moan as he hilted himself in her. Sarah tried to stay angry, or failing that at least to get some control over the situation, since she was technically being raped, but at the same time she knew the boys wouldn't harm her. And it was impossible to really stay angry at the cute little zebra grinding his crotch into hers after he just gave her his virginity. So she tried to relax and enjoy it, closing her eyes and even moaning as Toby drew almost all the way out of her, his young cock shinny with her juices, before he slowly pushed himself back inside her.
Her tentative sensuous mood was broken as she felt a hand move her head to one side and something push itself into her open muzzle. She opened her eyes to see Tommy's black and white crotch as well as the half of his shaft he didn't manage to stuff into her mouth. Yet. She glared at the boy and tried to mumble something around the thick equine meat filling her mouth, but judging by the blissful expression in his face he was unaware of his sitter's disapproval. Seeing how there was nothing she could do, Sarah wrapped her lips around the colt's shaft and started to suckle on the appendage, reasoning that the sooner she got him off, the sooner he would take it out of her mouth. She swirled her tongue around the ridge of the slightly flared head, and was rewarded with a squirt of pre. Sarah was surprised to find that she actually liked the way the boy tasted and swallowed his juices, knowing that the same stuff was being squirted in her other end, as Toby picked up his pace.
Toby was in heaven, drinking in the sight of Sarah's soft body splayed out on the couch, covered in that soft, downy fuzz. His loved the way her perky boobs, still damp from their first loads, shook and bounced every time he drove into her. Looking down, he felt kinda proud at the way his young shaft filled her pussy, she being almost an adult. Those thoughts drove him to hump her a little faster, their juices now dripping from her cunny, some of them running down his glistening shaft to coat his little black pouch. His young sack was now slapping into the ewe's shorn cheeks, Toby gasping slightly whenever her fluffy tail tickled it. Looking at his sitter's pussy lips splayed around his rod he noticed a small pink nub at the top, and with a 12-year-old's curiosity gave it a little rub. That seemed to have an effect on Sarah as the ewe arched her back, moaning around his brother's shaft in her mouth, her pussy clenching and twitching around his own length. At first Toby was afraid he'd hurt her, but after a few seconds she seemed to settle down, still making little moaning sounds through her nose, her chest rising and falling as her breathing intensified. Realizing she must have liked that, Toby went back to rutting her, every now and then brushing a finger gently over the little nub and being rewarded with the ewe's inner walls caressing his shaft she writhed on the couch.
Sarah was starting to wonder just how much porn the twins had watched, Toby now playing with her clit as he kept thrusting into her while Tommy had both hands on the back of her head as he fed two thirds of his immature cock into her mouth. Her tongue was now pinned against the underside of his rod as the tip almost touched the back of her throat. All she could do at this point was swallow the pre leaking from the colt's tip to stop from choking as his brother intensified his humping. Aside from the twins' admittedly cute gasps and moans the room was now filled with wet smacking sounds as Toby slammed his little hips into Sarah's crotch with every thrust. The young ewe had to admit she was enjoying the sensations coming from her lower half, her pussy having adjusted to the thickness of the colt's shaft. She loved the way the medial ring rubbed her walls as it pumped inside her, and felt a little jolt every time it nudged her lips when going in and out.
Toby intensified his pace, his thrusts becoming shorter and faster as he felt his climax approaching. He gripped Sarah's slim waist, the ewe now holding her legs open of her own accord as he slapped into her, the taught lips of her pussy gripping around the thickest part of his shaft. He felt his orgasm hit him as his tail flagged and his balls contracted, sending pulse after pulse of hot zebra cream deep into his sitter. The exhausted kid almost collapsed on top of the ewe. He buried his face in her breasts, not minding that some of the goop he and his brother had left there was smearing on his face as he wrapped his arms around her, his cock sending out a few last spurts into her belly.
Sarah came fiercely when the colt plunged all the way into her, feeling his tip flare up and his shaft throb before filling her with the boy's cum. That triggered her own climax and she felt her pussy clench around the length inside it, milking the boy of every last drop. She was glad she was on the pill and allowed herself to bask in this moment, the feeling of a boy coming inside her being her favorite part of sex. She let out an 'Oof!' through her nose when she felt the Toby collapse on top of her, and probably would have awwed when she felt him hug her and nuzzle her breasts if she didn't have about five inches of zebra cock plugging her mouth. The afterglow was short lived, and she was surprised when the shaft in her muzzle was pulled out, the slightly flared head making a pop as it slid past her lips.
"C'mon, it's my turn! Quit hoggin' her!" Tommy whined, nudging his brother's shoulder.
Oh, good. And here I was worrying they were growing up to fast. She thought bitterly as Toby gave in to his twin's pestering and climbed off her, his soft cock pulling out of her with a wet pop as the flare came out, followed by globs of cum that trickled down Sarah's crack. She was surprised how much the colt had left after the loads the twins shot on her chest, and blushed at the sight of the kids staring at her well-bred pussy.
"Aww, you've stretched it all out. Look!" Tommy complained as he moved between the splayed legs of his sitter who was beginning to lose her patience.
"Well, I'm so sorry if - Eeep!" she winced as the boy probed around her sensitive folds to prove his point " you're too good for sloppy seconds! If you don't want a turn then you can untie me and you can both go to bed. And if anyone isn't sleepy, they're welcome to all the warm 'milk' that you two have pumped in or on me!" she hissed through her teeth, Tommy's pickiness getting on her last nerve.
The two got worried for a moment, but soon relaxed, remembering their sitter was still tied up, and confident in the skills that earned them their knot badges.
"I wanna do her butt!" Tommy exclaimed.
"Are you stupid? You can't have sex in the butt!"
"That's absolutely true!" Sarah added, literally lying to save her ass. She never had anal sex, and considering how stuffed her cunny got, she didn't want to lose that particular virginity to an equine cock.
"Can too! We just need to get her butt a little higher. Lift her bottom up for a second, will ya?" Tommy said and to Sarah's horror his brother obeyed. Toby put his arms around her hips, and hands resting on her cheeks pulled her ass up, allowing Tommy to slide several thick couch cushions under her. When she was let go she saw that her mound was now pointing upward, and her ass must have been just the right height for a colt kneeling on the couch.
"OK, that's good. Now we just need to loob-ra-kate her." Tommy said, struggling a bit with the unfamiliar word. Sarah wasn't sure whether she should be worried that the boy was intent on penetrating her virgin ass, or grateful that he at least knows enough to use some lube.
"How are you gonna do that"?
"Well, you take some clear goo, and smear it all over your thing and hers, and that makes them both slippery."
"And do you have any of that stuff?"
"Well, no, but..." Tommy trailed off and Sarah gave a squeak as she felt the boy spread her puffy lips, his fingers scooping up some of his brother's cum from her sore folds. She blushed at the sight of the two colts staring at her oozing pussy, but her embarrassment was soon replaced with dread as she realized what Tommy's plan was.
"No! Tommy, listen to me, do nNnnngggh!" Sarah's protests were cut of as her eyes bulged and her jaw clenched when she felt a slippery little digit prod and then slip past her pucker. Despite her ass clenching around the digit, the boy kept wriggling his finger deeper inside her.
"See, it's working! We'll just need some more." Tommy said before shoving two fingers on his other hand into her pussy, trying to scoop some more 'lube' out of the ewe. Sarah grunted, surprised by the strange, but not unpleasant feeling, as the colt's fingers rubbed the wall of her tunnel, pressing it against the digit buried in her rectum. She clenched her mouth shut, not wanting to encourage the boys any further. After getting some more of his brother's spunk near her hole, Tommy pushed in another finger. Once Sarah's pucker stopped clenching at the intrusion, the boy started to pump them in and out of her now slick opening.
"See, as long as you make it slippery, it can stretch around anything!" Tommy proclaimed optimistically. Sarah was a bit more skeptical, although she had to admit that now that her muscles relaxed a bit it was no longer painful, and not entirely unpleasant. After about another minute, Tommy withdrew his fingers, and Sarah curled her tail to hide her button from the two boys.
"Tommy, I can't believe I'm saying this, but would you stop being picky and just stick it in my pussy?" trying to glare at the boy as he moved her fluffy tail out of the way and aimed his blunt tip at her pink pucker. The next sound out of her mouth was a startled squeal as the boy gave a thrust of his hips and popped his head in surprisingly easy. The experience must have been much more rewarding for the colt, his face melting into an expression of pure bliss as he lowered his torso on top of her, supporting himself on his arms while his cock slipped in another few inches into his sitter's no longer virgin ass.
"Slow - hnngh! - down!" Sarah groaned as the boy squirmed closer to her, impaling her on more of his young shaft.
"How does it feel?" Toby asked his brother, looking at Sarah stretched ring with curiosity and a little envy. He wondered if he chose the wrong hole to begin with, and wondered if Sarah would let him mount her ass when his twin was done. Judging by the expression on Tommy's face the first seemed likely, and judging by the grimace on Sarah's the second didn't.
"Ahh-amazing! She keeps squeezing around me." Tommy panted. His eyes were now level with Sarah's boobs and he was enjoying the view as he slowly fed more of his length inside the prone ewe, eager to bury himself to the hilt in her soft, warm body.
                "So glad -nff! - at least one of us is enjoying this!" Sarah said sarcastically, although the sensation was kinda pleasant. Still, she was pretty sure that having her ass fucked alone wouldn't get her off. If she was being honest, her pride hurt more than her rump, and her inner sitter raged at the thought of being dominated this way by a twelve year old.
                Tommy did feel kinda bad that Sarah didn't seem to enjoy having her butt stuffed as much as her pussy, but being inside her felt too good for him to even consider stopping. Instead he tried to make it feel better for her, lowering his muzzle to one of her nipples and giving it a flick with his tongue before locking his lips around it and suckling it gently. He was glad to hear Sarah stifling a moan instead of a grunt, and kept sucking and kissing the now stiff little nub. This seemed to relax the ewe and the boy used that opportunity to push the rest of his shaft in, Sarah wincing slightly as his medial ring slipped past her pucker. Tommy switched to the other nipple and repeated his treatment, and soon the ewe gasped when the boy's tummy touched her slit, his shaft now completely buried in her sore rump.
                Sarah was finding it it harder to stay mad Tommy, the colt looking adorable as he gently kissed and suckled her sensitive breasts. Almost makes you forget the sodomy she thought. Feeling him grind on her empty cunny sent a few pleasant jolts through her body, and Sarah whished at least one of her hands were free so she could play with her cunny, remembering how good the boy's finger's felt in there the same time her ass was stuffed. She settled for grinding her crotch into him, savoring the sensation of her clit rubbing against his pubis. She managed to get herself worked up, and almost mewled in disappointment as the colt withdrew half his rod out of her ass and pushed it back in, the boy moaning as he started to breed her bottom.
                Standing behind his twin, Toby had gotten hard watching the zebra colt pump their sitter's ass, and some boyish part of him made him unerringly lust after the toy his brother was playing with, which in this case was a round, soft butt. He was getting mopey since it didn't look like Sarah would let him have his turn with her rump. He knew they could only push their sitter so far, since they would have to untie her sooner or later, and if they got her really mad their own bottoms would feel her wrath. Or more likely, her palm. 
The thought, combined with the sight of his twin's butt rising and falling as he humped away into the ewe, made him think how hilarious it will be to give Tommy a really hard smack across both cheeks while his guard was down. Then as the colt's tail flagged, he caught sight of his brother's little black pucker, and he got quite a different idea. His ass was smaller than Sarah's, but didn't Tommy say butts could stretch around anything as long as it was slippery? And looking down, he saw his shaft was still slick after his turn with Sarah, and starting to leak pre from the tip the more he thought about this. He made his decision and carefully positioned himself behind Tommy. The next time the colt drew out of the ewe's ass, he felt his own button bump against something hard and moist.
"What the..." before he could swear Tommy screamed as his brother grabbed his tail and forced his blunt head into the colt's tight ass. Sarah had closed her eyes for a few moments, imagining it was Tentacleman on top of her and inside her, and they shot open at the sound of Tommy's somewhat girlish scream only to see his twin standing behind him, one hand gripping the base of the boy's tail, the other on his butt cheek. It didn't take her long to figure out Toby had just taken his brother's anal cherry, and by the grimace on the bottom colt's face, she figured he wasn't enjoying it. One part of her felt sorry for the boy, but another part was gloating. Karma's a bitch,huh kid?
"Oww, it hurts! Take it out, Toby!" Tommy whined, trying to in vain to wriggle out of his brother's grip, but bent over and buried in Sarah he wasn't going anywhere. Judging from the expression on Toby's face he couldn't hear him, and his eyes seemed glued to his brother's poor butt as he pushed another inch in.
"Aaah! Sarah, make him stop!"
"Oh gee I'd love to, Tommy! But unfortunately I'm a bit tied up at the moment, and somebody shoved his cock inside me, even though I asked him not to." Sarah knew this was wrong, but it felt so good!
"Don't - ahh! - worry, Tommy. I'm slippery and you said a butt stretches around anything as long it's slippery." Toby said, giving his brother a little time to adjust to having his cock inside him.
"That's right, Tommy, you did!" Sarah said gleefully. The boy resigned himself to his fate and buried his face in the ewe's bosom to hide his embarrassment at being taken like a girl. Sarah felt a little bad at having teased him, and craned her neck so she could kiss the top of his head as the boy let out little pained noises into her cleavage. Her eyes however, were pointed up. Two boys doing it was always a kinky little fantasy of hers, and now that it was happening right in front of her, she didn't want to miss a moment of it.
Tommy felt like his cheeks were burning more than his abused pucker. It had hurt a lot when Toby had first pushed himself inside his hole, but as he relaxed on top of Sarah it became just uncomfortable and... weird. His brother's rod was getting in deeper and deeper, squirts of pre making the penetration easier, and seemed to rub against something inside him that felt kinda nice. It also made his thingy twitch inside their sitter's rectum, making her ass squeeze around it which felt even nicer. After a while he felt his brother's hips bump into his butt, the other colt's little sack brushing up against his own and he realized he'd taken his entire length inside him.
Toby groaned when he hilted himself inside his twin, admiring the view of the colt's little black pucker stretched taught and twitching around his ebony shaft. He held still, waiting for his brother to adjust to having his length inside him, feeling a few more spurts of pre shoot from his tip and into his twin's ass. He put his hands on the boy's cheeks, squeezing them slightly and admiring how cute and girly he looked from this angle. He decided to try and make Tommy feel good, like he did for Sarah, and maybe he would let him do this to him again sometime.
Even though she wasn't enjoying anal that much, the sight of the little zebra colt lying on top of her, with his face buried between her breasts and his shaft buried in her ass while his brother drove his own cock inside him was stimulating enough. Judging the way his shaft twitched inside her, Tommy was enjoying his first cock at least a little. She kissed the top of his head as his brother started grinding into the colt's butt, driving him further inside her and making him gasp.
"Now Tommy, just relax and try to enjoy it. Toby, be sure to take it slow and easy, or else when this is over I'll make sure your butt is just as sore as his!" she said, trying to reestablish some control over the kids.
Tommy surprised himself with the sounds he made when his brother pulled almost all the way out before slowly hilting himself again. He sounded kinda like Sarah did when his twin was pumping her cunny. He felt embarrassed he was making girly noises, but he couldn't help himself. Now that his ass was stretched out and lubed up even more by his twin's pre he felt a sharp tingle every time the other boy's shaft nudged something inside him, making him send his own spurts into the ewe underneath. He wanted more of that feeling and started pushing his ass back to meet his brother's thrusts and moaned even harder as the tingling got more intense and his own cock sawed in and out of Sarah's butt.
"Tommy, could -mpf! -you use your hand to play with my pussy?" Sarah said trying not to sound too needy, but now that Tommy was once again sliding in and out of her asshole, the sights and sensations were bringing her agonizingly close, and she knew she'd need something in her snatch in order to cum.
Seeing his brother was getting into it, Toby stopped thrusting and just rested his hands on his twin's rump as Tommy impaled himself on his shaft over and over, one hand fiddling with Sarah's slit as he in turn plunged into her. Even now that it had relaxed, Tommy's ass felt wonderfully tight and after a while Toby started humping into the colt again as he felt his pleasure mount. His brother let out needy little whimpers as Toby picked up the pace, his hips slapping into the other zebra's cheeks as he drove himself into that glistening little pucker. Sarah's moans joined his brother's, Tommy apparently having found her sweet spot. That spurred Toby on and he started making short, fast jabs, his own little butt clenching rhythmically as he got ready to breed the other colt's rump.
Tommy was past caring what kind of sounds he made, the pounding of that special spot inside him combined with Sarah clenching around him making him moan and gasp as he nuzzled the ewe's chest, his face now completely smeared with the twin's combined cum. He squealed as Toby gave one last thrust, shoving himself as deep as he could into his twin's ass. The other colt's tip started to flare, the pressure on his nub bringing Tommy to the edge. When he felt the first spurt of his brother's cum shoot inside him he blew his own load into the ewe beneath him, groaning blissfully as his balls emptied and warm seed flooded his ass, his pucker clenching and milking his twin's cock.
Seeing the little colt take his first load, combined with the one he dumped inside her and the clenching of his hand buried knuckle-deep in her snatch sent Sarah over the edge and she cried out as she gushed over the boy's hand, cumming harder than she ever had. She writhed on the couch as hot cum flooded her ass, knowing that the boy on top of her was feeling the same warm rush as his brother bred his coltish rump. After they got their breath back, Toby withdrew his softening cock out of his brother's ass, the other colt gasping when the tip popped out with a wet sound followed by a small trickle of his twin's seed. Tommy then got off Sarah and standing somewhat bowlegged looked at the sight of his cum dribbling out of her still stretched pucker, imagining what his butt must look like. Without a word spoken, they untied Sarah's hands, and retreated to a safe distance as the ewe undid the knots on her legs, giving her the pleading look they usually used when threatened with vegetable casserole.
After agreeing on a general amnesty, which happened right after Sarah explained what 'amnesty' meant, they all cleaned themselves up (Sarah calling dibs on the shower and daring the boys to challenge her) and decided to call it an early night. The twin's went to their own rooms while the ewe made a bed on the couch she was just gang-banged on. Cleaning the couch proved easy enough, her fluffy tail having soaked up most of the juices. It still smelled of sex and as a consequence the ewe's dreams proved quite stimulating, her mind conjuring up a harem of striped little colts, preforming various sex acts on and for her. After leaving the bathroom later that night she even walked past the boy's bedroom doors, trying to hear if one of the twins snuck into the other's bed for a little fun, but was disappointed that the boys seemed to be sleeping in their own rooms. Still, the Millers wouldn't be beck until Monday morning. Tomorrow would likely be an eventful day...
