Never do a job too well!  Stacey thought bitterly as she sat in the living room, bored out of her mind while her brother and his friend, Nathan, were having the time of their life playing video games. The last time she’d babysat her 13 year old brother their parents were noticeably nervous about leaving the two of them together, worried that the siblings’ spats would escalate into full-on warfare during a weekend without them. When they came back from the wedding, they were pleasantly surprised to find everything in order. Their children even seemed to get along better, and the pair figured they must have spent the weekend bonding.
Stacey grinned, remembering the night she and her girlfriend Becca found Mark spying on them. They had blackmailed the young mouse into playing dress-up, and gave him a crash-course on female intimacy. That had been two weeks ago, and when her parents had told her they were going to spend a weekend away together (and she’d managed to block out the images of what they would be doing) she was thrilled. The 18 year old mousette immediately got on her phone to arrange a booty call, and that’s when her plans sank. It turned out Becca would also be out of town, visiting some relatives with her folks.
And just like that a weekend of getting screwed silly by the hyena she loved went down the drain. She’d even figured she might lure ‘Marcy’ back to her room, but when her brother asked if Nate could come over, she realized even that was a bust. She wondered if maybe they went a bit too far with him the last time and put him off the idea. Still, he definitely seemed to be enjoying ‘herself’ while they were at it, and the part of his face not buried in his sister’s muff at the moment he came from being butt-fucked by Becca’s clit-cock looked blissful. She hoped the reason he didn’t approach her again was that it would be weird for him with just the two of them. Or maybe Marcy’s all about the pseudo-cock! Since she was now stuck here with nothing and no one to do, she decided she deserved a little treat. And she knew from experience she would need some junk food afterward.
“Mark, I’m going to the grocery store, be back soon.” she said, putting on her jacket.
“Okay!” Mark replied, never taking his eyes off the screen. The moment the door closed behind Stacey, the mouse and the fox shared a knowing look. Pausing the game, they practically bolted upstairs, straight to Mark’s room. They could play videogames while Stacey was there, and while she was away they intended to watch a few videos. A quick click on a ‘Yes’ button under the question ‘Are you 18 years or older?’ and the screen on Mark’s computer was filled by a veritable pornucopia. By unspoken agreement, they started with a girl-on-girl video, a pretty good one of a busty vixen riding a bunny’s face and exposing the lapine pussy to the camera. Each of them had dropped his pants and started playing with himself. The two cubs had known each other for as long as they could remember and were comfortable enough with each other to masturbate together, especially since both were certain there were better things to look at on screen than between your best friend’s legs. Although after his night with his sister and her girlfriend, Mark found himself taking an occasional glance at Nate’s red shaft.
They were casual glances at first, with Mark worried about getting caught until he realized nothing was going to pull Nathan’s eyes away from the screen. The kit was bigger than he was, especially now that his knot was out of the cream-furred sheath and throbbing as the young fox polished his red rod. When Nate blindly reached out and grabbed a fistful of tissues Mark wasn’t surprised. The kit had a short fuse and would blow his first wad quickly enough, and most of the time the mouse sitting beside him would barely even notice the groans that signaled the kit’s release. This time he was struggling not to stare at the length of vulpine flesh throbbing in Nathan’s grip, and the twitch of the little fuzzy sack under it. He’s smaller than Becca the mouse mused, wondering where that thought had come from and why.
The video had finished but Mark still hadn’t, so he clicked on a video of a cheetah being spit-roasted by two large wolves. After the girl was filled on both ends the boys agreed to pick another feline next, and Nate picked out one of a cat taking it in the ass from a stallion. The feline was bent over the bed with the horse kneeling behind her and the camera had a great side shot of the giant rod disappearing into the moaning female. She was pretty enough, short haired and flat chested but with an amazing round ass. They got another great look of it as the angle switched to a top shot, showing the stallions cock piston in and out of the stretched ring. The two were now stroking themselves furiously as the room filled with the cat’s pants and moans, when the angle changed again, this time showing the underside of the couple. And the boys both stopped mid stroke, their eyes wide as they noted the absence of a wet kitty pussy, and the unexpected presence of a small but very erect feline cock. Then they realized that they’d focused so much on the thumbnails and previews that they missed the clip’s title: Stallion rides pussy twink.
“Wow, that was… weird…” Nate said, pausing the video. Mark couldn’t help but notice that neither of them had taken their hand of their cock.
“Yeah…” he replied, glancing at the screen. He wasn’t sure about Nathan, but seeing that the cat was a male didn’t turn him off. What’s more, the sight of the feminine cat being mounted by the stallion reminded him of the time Becca had taken his boy-cherry. He’d never come as hard as that time, and he still remembered how his young cock twitched and spurted in the hyena’s grip while her shaft twitched inside his ass.
“Can you imagine ever doing something like that?” Nate asked jokingly, obviously trying to break the tension, and never realizing his friend was remembering doing something like that.
“Kinda…” the word had left his mouth before he could stop himself.
“What do you mean?” Nate asked, unable to believe that his friend had apparently not only had sex already, but had managed to talk a girl into anal.
“Look, if you want me to tell you, you have to promise to keep it a secret. No one can now, OK?”
“OK, I swear I won’t tell a soul.” Nate replied.
“Well, I sorta already had sex…”
“Seriously? Who’s the lucky girl?” Nate asked, his envy failing to match his curiosity.
“It was kinda… two girls. My sister and her girlfriend Becca.”
Nate’s jaw actually dropped as his brain took in the information. He’d had the hots for Mark’s sister for some time, and his feelings definitely didn’t change when he learned she had a girlfriend. He’d even had a few very pleasant dreams featuring her and Becca. He began wondering why Mark hadn’t bragged about this to him and every other boy he knew, figuring it must have been the fact that one of the girls was his sister.
“So, did you, like… both of them?” he asked, desperate to hear more.
“Kinda… Turns out, female hyenas have a really, really big clit. So big it’s almost like a dick.”
“So the two of you did Stacey together?”
“Not… really…”
“You mean Becca did Stacey and you did Becca?”
“You’re getting warmer.” Mark said, his cheeks turning red as he tried to figure out a way to tell his friend what happened. Nate looked confused as his blood-starved brain tried to run through all the possible combinations. Mark looked back at the computer screen and following his gaze to the sight of the impaled feline on pause, he finally got it. Nate proceeded to tell his friend the whole story – how he got caught spying on them, the make-over the two gave him, and how they taught him how to fool around like a girl. He actually felt a little thrill as he described how Becca had mounted him and how good it had felt.
 “Wow. So did you ever… do it again?” he asked, his mind still trying to process what his ears had heard.
“No…”
“W-would you?”
Mark didn’t say anything, even averted his eyes so he wouldn’t have to face Nate, feeling his heart beat a bit faster. There was no mistaking what the kit was asking of him, and the young mouse found something inside him responding, overpowering any awkwardness he was feeling. The image of the kit’s cock twitching, spraying into a fistful of tissues… sure, Nate had the knot, but it didn’t look all that big. He was sure Marcy could take it. Still, if he was going to be a girl for Nate, there’s a few thing’s he needed.
“Okay, just… wait here for a minute.”
A split second after he’d asked Mark that question, Nate began to worry that he’d just made huge mistake, and possibly ruined their friendship, so his mood did a complete about-face when he heard the mouse-boy’s reply. He just nodded as Mark left the room, and sat there for what seemed like forever, but was probably closer to a minute or two. Then Mark came back in…
He had no trouble finding the summer dress and the butterfly barrette, and had even managed to brush his blond hair to one side and fasten it, like his sister had done that night. He went back to his room and blushed when he opened the door and Nate saw him. Any thoughts that he was making a mistake were soon dispelled when he noticed the kit’s five inch shaft twitch at the sight of him. He silently made his way to the bed, knelt down and bent over it, just like the cat in the video they were watching. He saw Nate get up, taking his pants and t-shirt off as he got behind him. He raised his tail, which in turn hiked the dress up, exposing his rear to the kit.
“C-call me Marcy…” he said, looking back at his friend who was now kneeling behind him.
Nate just nodded mutely at the sight of… Marcy… offering herself to him, the mouse’s tail hiked up showing a pink pucker between two pert young cheeks. With the dress bunched up around her waist, Marcy’s perky butt looked just like a girls, and even her still undeveloped mouse-tackle looked feminine. The virgin kit was so aroused by the sight that any misgivings about his sexuality, about doing this with his best friend went out the window. Fortunately, some part of his brain was still operating. He grabbed the hand-lotion, an integral part of the pair’s fap sessions, and squeezed a glob on his finger.
Mark knelt there anxiously, his heart beating in his bra-covered chest as he waited to be mounted by the fox. He gasped as he felt something cool smear over his pucker, the ring tensing up on reflex as one of Nate’s digits covered it in lotion. He felt touched, in more ways than one, that his friend was taking the time to get him slick and ready, and also a little worried that it hadn’t occurred to him. He still couldn’t believe he was doing this. Playing Marcy had been one thing when it got him in on the fun Becca and Stacey had, but now he was raising his tail and presenting his ass to a boy. But only a minute ago they were furiously masturbating to what turned out to be a feline femboy getting pounded, and neither of them had lost their erections when the male cat’s boy-bits were revealed.
“Aah!” he squealed when the kit’s digit popped inside, interrupting his train of thought with the familiar sensation of fulness under his tail.
“Sorry, did that hurt?”
“No, just surprised me…” he replied. Compared to Becca’s energetic treatment of Marcy’s rear, the kit’s cautious touches were much gentler. Mark relaxed his pucker, allowing more of her friend’s finger to slide into ‘her’ ass.
“Wow, it’s all the way inside you! Does it hurt?”
“Mmmh, no. Feels nice. Now just move it out then in, slowly.” ‘Marcy’ said, the cross-dressed boy sighing girlishly as his friend started fingering the snug tail-hole. The kit had settled into a steady rhythm and the young mouse found himself biting his lower lip to stifle his moans, still feeling a bit self-conscious about the whole thing. When Nate carefully slid another finger inside him he couldn’t help letting out a distinctly feminine gasp, his slick tail-hole clenching around the kit’s fingers as they pumped in and out.
“Uh, Marcy, can I…” 
Mark craned his neck and one look at the kit’s twitching vulpine cock told him just what his friend was trying to ask. Blushing, the young mouse gave a silent nod and watched Nate position himself directly behind him, his hands tentatively reaching out to grasp his cheeks. It occurred to Mark that the kit was about to lose his virginity to him, and the thought gave the boy an extra thrill. He heard a slurping sound and realized Nate was smearing lotion on his cock. He couldn’t see behind him, so he focused on the sound of the kit polishing his shaft, the feeling of his other hand gently squeezing a perky young cheek, and the sensation of his little cock dangling between his legs.
Then he almost jumped when he felt a spurt of something warm hit his pucker a second before the kit’s warm, tapered tip nudged up against it. ‘Marcy’ found herself taking deep breaths, the fox behind groaning as he gently pushed his maleness against that tight ring, slowly but surely stretching it around his squirting length. The sensation of something spurting inside him was new to the mouse, and with that sensation came the realization that Nate would not only fuck him but actually fill him with his seed, something Becca, for obvious reasons, couldn’t do. For some reason the thought of another boy leaving his cum inside him turned Mark on even more, and before he could think about it he’d arched his back and pushed his ass out, squeaking as his boy-pussy swallowed the first inch of the vulpine rod.
“Are you OK?” Nate asked, the concern in his voice failing to outweigh the arousal he felt as Marcy’s snug pink pucker clenched around his tip.
“Yeah. Slide it all the way in, just – ahh! – take it slow…” Mark replied in a shaky voice as he was felt the inches slide in. His voice had sounded appropriately girly when he spoke, but he wasn’t sure a boy his age could sound masculine while dressed as a girl and taking another boy’s cock between his cheeks.
The kit didn’t need much urging, pushing slowly and watching his friend’s ass swallow his red shaft, his pink pucker now almost invisible as it stretched around the vulpine member. He grit his teeth as that opening squeezed around him, worried that he might cum too soon. He had no idea if Mark, that is Marcy, could cum from this, but if his best friend was willing to let him fuck her, he might as well do his best.
Mark did his best to take deep breaths and fight the instinctive urge to clench up. As the warm fox-cock went further and further inside him, he kept letting out little squeaks and moans, reveling in the sensation of being filled. A slight nudge told him that his friend had shoved everything inside him but his still uninflated not, and the mouse relaxed as best as he could, taking a deep breath as his little hole was stretched just a little further. The unswollen bulb wasn’t much thicker than the rest of the boy’s cock, and ‘Marcy’ let out a gasp when it slipped in, swallowed up by her tail-hole just as Nate’s hips touched her butt.
As the kit paused with his shaft hilted in the mousey rump, Mark couldn’t help but notice the difference between this and the other times he’d wound up with someone filling his ass. There was something eager yet hesitant in Nate’s touch and he wasn’t sure if he was imagining it but he could almost feel the kit’s paws tremble as they smoothed his sleek gray fur. It didn’t have the same near-scary thrill as when he felt Becca grope his pubescent ass, but he was horned up enough to overlook the clumsiness of the virgin fox’s touch and just enjoy himself. Arching his back he thrust his rear out, feeling his cheeks spread and hearing Nate’s gasp as it pushed the grey-furred rump against his hips.
“What do I…” he heard Nate ask, the vulpine paws never leaving his cheeks.
“Just wait a little…” he murmured. There was no hint of pain in his voice but this was still the intense part, with his ass clenching every now and again, trying to push out the invading length. It felt kind of nice, especially since it seemed to press Nate’s knot right against that special spot inside him that Becca could always unerringly graze. And whenever she did Mark would make distinctly feminine noises that so thrilled both the hyena and his sister. He wondered how his best friend would take to hearing such sounds coming from his muzzle…
“Okay, go ahead. Just start slow at first, okay?” he said.
“Y-yeah…” Nathan replied, sounding breathless as he carefully slipped the tiny knot from the tightness of the mousey rump.
As the fox boy began o slowly slide back in, Mark was feeling every hot, hard inch of him but he couldn’t help but notice a difference in the way Becca had taken his ass and the way Nate was slowly humping against him. It only then occurred to him that ‘Marcy’ had just taken the kit’s virginity, and that this time round he was the experienced one. The fox boy gently pumping a vulpine shaft under his tail seemed a little awkward, but definitely enthused. Mark could feel every throb and twitch of the kit’s cock, and every once in a while he could even feel the rosy rod squirt pre into him. That was another thing Becca didn’t have, and even though his sister’s girlfriend could and did fuck his brains out with that pseudo-penis of hers, she’d never pumped him full. He remembered the way Nate’s sack looked when he came, twitching as it turned a fistful of tissues into soggy pulp. The idea that the next time that cream-furred sack started to twitch he’d be the one taking the kit’s load made his heart skip a beat, his back arching just a little more as he pushed his ass out to meet Nate’s increasingly energetic thrusts…
*******
Climbing the stairs Stacey passed by her brother’s closed bedroom door and her ear had twitched at the happy feminine noises coming from the other side. She slowed her stride, but didn't reach for the knob. Her parents weren't very tech-savvy so she figured the boys had gotten around the parental blocks and were even now glued to the screen watching some grown-up entertainment. Not really something she felt an (unpaid) babysitter needed to get involved in, although she had to admit the girl sounded hot. 
So she proceeded to her own room, figuring she might also enjoy some private time, a plan that sank when she saw that her closet and one drawer were open. Rage rose up within her at the idea that the little creeps had stolen some of her undies and were even now doing unspeakable things to her unmentionables, but the drawer that had been quickly rifled through didn't really have anything of interest to a pair of pubescent boys. It was just some little accessories, her makeup, assorted scrunches, hairbands and...
And an old barrette with a little bow she hadn’t worn in years was missing. A quick check in the closet confirmed that a sundress was also gone, one that was too small for her but a surprisingly perfect fit for…
"Marcy!?" she said to the empty room. But it didn't make sense - why would her brother assume the alter-ego she and Becca had created for him when there was no intimate girls-only party taking place? Was it possible that Becca put him up to it? Was her family trip just a ruse and had the two of them planned some sort of surprise for her? A nice thought, but Stacey knew the girl she loved didn't have the patience for such schemes. If she could have, she'd already be here, screwing both her and Marcy silly. Her feet carried her back to her brother’s door, big round ears perked until they once again caught the feminine voice making happy noises. And squeaking!
Stacey's tail whipped behind her and before she knew it she was holding the knob, turning it ever so gently until the latch gave way without an audible click. She opened it a crack, but since that crack gave her a view of Mark's bed, it was enough. The mousette covered her mouth at the sight of an orange-furred back, a bushy tail swaying up and down with the motion of the kit's hips, and the small figure wearing a pretty sundress that had been flipped up to reveal a perky grey ass. ‘She’ was on all fours on the bed in front of the humping kit, the hair her sibling had let grow long combed to one side and pinned with a pretty bow. From her vantage point Stacey couldn't see the good stuff, but the gasps and squeaks left little doubt as to what was happening.
He's fucking my kid brother! she thought as the vulpine hips worked in  the jerky rhythm of a virgin.
She was still reeling from this, even after the stuff she and Becca had done with the mouse even now lifting her tail for the boy next door. It might have been... confusing for her kid brother, but she and Becca were both girls, even if the hyena had given it to him better than the kit grunting with every awkward thrust. Was her little brother really her little sister deep down? Was he gay? Were these two in love, or just doing what horny pubescents did when they got the chance? And should she be watching?
Well, this all started because Mark was spying on me and Becca. And recording it. And he was probably going to share it with this little fucker!
The line of reasoning was good enough for her, making her feel vindicated as she continued to stand in the doorway and watch. And listen! Mark was even in character, making the sounds Marcy had made whenever Becca was sloughing her perky tween tush. The hyena had been a tight fit for her sibling, and as Stacey wondered what Nate was packing she couldn’t help but push her head in, trying to get a glimpse. It was enough so she opened the door a little bit wider and carefully stepped in. The two were going at it and didn't even notice they had an audience, and now Stacey could just lean in a little and...
Hmmm, not bad kit... the mousette mused, surprised at how the sight of the slender red rod pistoning under Marcy's tail was making color rise to her cheeks. Stacey had never been attracted to males, but after her adventures with her brother in drag she'd come to view boys differently than men. After all, if a boy like Mark could be turned into an adorable girl like Marcy by two stoned teens the line separating them wasn't as clear as she thought. Nate had a cute face, and the butt clenching up every time he thrust into his 'girl' looked adorable, so who's to say he wouldn't have made a sexy little vixen? Although the cock railing Marcy's ass was more substantial than the one bobbing between her sibling’s skinny thighs. But then Becca was a girl and she had them both beat. Although she didn't have a knot. Or that plump little pouch...
The idea that her brother was not only letting another boy fuck him but that he'll probably end up taking the fox-boy's load made the mousette's thighs rub together, and since the boys were too busy to notice her she let a hand slip under the waistband of her shorts, into her panties and letting it slip past her dew-damped folds. She wondered how long she could get away with this before the two humping pubescents noticed her. Nate had his back to Stacey and 'Marcy' seemed to be staring at the wall in front of her as she squeaked and moaned. No stains under her sibling but the young mouse's slender cock looked painfully stiff as it bounced and slapped the trim tummy. No denying she was enjoying it. For all Stacey knew, Marcy was the one who seduced the kit who was very obviously fucking for the very first time. Marcy, you little slut! she thought, strangely thrilled by the idea of her baby brother using his alter ego to make men of the neighborhood boys.
Fingers dug in further, curling to stroke the sweet spots as the kit's cock did the same to her little sister's 'pussy'. His hair had really grown out nice, and he’d done a good enough job with the make up – a little highlights to emphasize his eyes and tinted lip-gloss did wonders. He was even arching his back like a girl who wanted it, throwing that cute tush out at the humping fox behind him. The kit's knot had been small enough to slip in and out of the mousey tail-hole without anything more than a wet pop and an occasional squeak, but it was getting bigger and more often than not it just dimpled her sibling's straining ring without sinking in. Stacey had never had a knot inside her, but she knew how they worked. She wondered if Marcy did and if she would let the fox humping her actually tie, her incisors biting into her lower lip. Her fingers curled and stroked the increasingly wet mouse-muff as she imagined that know plunging in and swelling up as Marcy squeaked and her kit groaned.
*******
Mark was oblivious to his sister's presence, alternating between staring at his pillow or at the wall in front of him. Having already blown his load once Nate had the stamina to really lay into him, his movements growing a little more confident as he gripped the mousey behind tight, slapping his hips into the squeaking and moaning 'Marcy'. There was no confusing the kit behind him with Becca, but to his surprise Mark wasn’t trying to pretend that it was the well-endowed hyena pumping his rump. He didn’t mind the fact that it was a boy grunting away back there. After all, Marcy was a girl so why shouldn’t she let a boy fuck her?
Flimsy as it was, the line of reasoning kept him from thinking too hard and just enjoying what he wanted. He was completely relaxed now, his body accepting the invasion of hard lupine flesh as the fraction of the kit’s cock made the grey mouse’s toes curl. Nate didn’t know what he was doing and couldn’t hit that special spot in his butt that Becca always attacked with a predator’s ferocity, but the tapered tip would graze it every now and again, drawing squeaks and gasps from the waifish boy. Nathan didn’t seem to be getting his knot in, something that was beginning to frustrate the mouse on all fours in front of him.
That thing had rubbed him the right way when it was just a tiny bump at the base of the kit’s cock, and he knew how big it grew by the time the fox was ready to cum. If he could only get that think up his ass it time he was sure to be amazing, and with that thought Mark started pushing his hips back to meet the kit’s thrusts.
“Ca-aaAah!-an you… g-get it in?” he squeaked, or rather ‘Marcy’ did.
“I… I’m trying. You’re –ngh!- tight!” the kit behind him groaned, the tone and the words making the mousey boy blush.
“L-let’s try… this…” Mark said, pushing himself up and his rear back, feeling the knot press against his stuffed pucker as he knelt with his back against Nate’ chest.
The kit took the hint and even wrapped an arm around ‘Marcy’, snaking it around her chest and even trying to give the mouse a grope. Nothing there but the padded training bra Mark was wearing, but her had to admit it felt kind of hot. After he ground his ass against his crotch a few times, Nathan took the hint and started thrusting up. Mark was soon squeaking again, and even if it failed to drive the knot in this position was getting his friend’s tip going where it needed to go.
The upward strokes were bouncing the mouse up every time, and he did his best to push down to meet the next one. The knot was now slapping against his messy ring every time, a hint of pain mixing with the pleasure as Mark’s well-stuffed tail-hole strained a little further around the vulpine bulge. The fox behind him was making funny noises as his grip grew a little tighter, making Mark bite his lip as Nate huffed against his neck with every buck of his hips, the two of them working in tandem to sink everything the kit had into the already full mousey butt…
*******
Stacey’s hand was a mess by now, her free hand tweaking a nipple as she watched the two tween go at it. The way Nate was hugging ‘Marcy’ close was adorable, and the way her sister was bouncing on the boy’s lap was downright obscene! The mousette had already shuddered her way through one orgasm, but her fingers hadn’t even slowed their pumping. Nor had those two! It was obvious the boys wanted the tie to happen and they seemed to be so close. They just needed a… a helping hand.
Stacey pulled hers out from her shorts, stepping out of the drenched pants and leaving them behind as she crept up behind the rutting pair. Not that they would have heard her if she’d walked in here in army boots. As she got close her eyes zeroed in on her target. Nate had such a gorgeous tail, thick and lush and so conveniently flagged up as he pumped his hips. And under it was an adorable little boy-butt, clenching furiously every time the kit drove in. A nice steady rhythm – one-two, one-two, one…
The lush orange fur didn’t muffle the smack of a wet hand connecting with firm young flesh, the slap followed momentarily by the yip of the fox and a split second later by a high squeak of the mousette in front of him. Shock and pain had made the fox-boy buck, and buck hard, in the same moment the grey mouse-tush was descending to meet the thrust. Stepping up beside them she became the center of attention of two stunned tweens who were in no shape to mentally process the implications of her presence.
“I…yo… we were just…” Nate tried to stammer out, but she silenced him with a wet finger pressed to his lips.
“Sshhhh… just give my sister what she needs…” she husked.
In retrospect it might have been a little too much. The kit’s nostrils flared to catch the scent she’d left on his muzzle, his eyes losing focus as his jaw went slack and a long, howling groan left his throat. A whimpering gasp from Marcy confirmed Stacey’s suspicions – having sunk somewhere warm and very tight, the kit’s cock was doing what it was designed to do and was even now churning out a load of watery vulpine spunk.
Leaving little Nathan on cloud nine Stacey turned her attention to her little ‘sister’. Her sibling was blushing so hard that the insides of her big round ears were almost glowing red, but Marcy did seem to be wincing a little even though her cocklet looked almost painfully stiff. She almost told her to relax, but she figured she could do better. She cupped Marcy’s chin and tilted her muzzle to the side, pressing her lips to the younger mouse’s in a brief, playful kiss. After a few more of those Marcy’s mouth opened and Stacey started twirling her tongue against hers, taking the knotted girl’s mind away from the pain so that she’d stop clenching up on reflex. A little tongue twisting, a few playful nibbles on Marcy’s lower lip and she was soon moaning softly into their kiss, in time to every squirt of the still climaxing kit.
Stacey very gently ran the back of her fingers along the underside of her sibling’s cock, the tentative touch making Marcy gasp, and grip the boy tied to her ass. She could tell by the smaller mouse’s expression that Nate’s knot was sitting right against Marcy’s sweet-spot, and that every time squeeze of her rump brought her closer to climax. She was sure simply gripping the mousey shaft would make it spray until that tiny grey pouch was empty, but that was how boys came. She kept teasing, running a fingertip across the leaky glans of her little ‘sister’, watching the pink length twitch but fail to erupt. She tried to remember what it was that Becca did to make their little playmate squirt, and once she remembered she pulled Nate’s muzzle closer to Marcy’s ear. His whiskers brushed against it, making the bog round lobe flick and on some for of instinct the kit caught the ear in his teeth and gave it a nibble.
Stacey bit her lip at the sound of her little girl gasping, laying her hand under his little pouch and feeling it twitch as Marcy shot milky white streaks all over her. The boy no doubt still cumming into that tight mouse-butt groaned around his mouthful as his lover’s ring began to pulse, the already snug tunnel milking his young cock dry. Stacey spent the time admiring the sight of the pink erection spewing it’s warm, stick load over her without being touched, thrilling to once again see her ‘sister’ squirt from nothing more than a good rump-rutting. Once the show was done and the mousey member began to grow soft, she took a moment to admire the two stunned tweens.
“Well, I see you’ve met my sister. Sorry for intruding on your private time, but I had to make sure you two didn’t get hurt… Speaking of, are you okay?” she asked her blushing sibling.
“Y-yeah, it’s just a little… ouch!” he said, wincing as he tried to pull away from Nate.
“You aren’t going anywhere soon. Just sit tight and cuddle because that knot’s gonna stay nice and plump for some time now that it’s got something gripping it.” She said, running a hand along her brother’s belly. “How does it feel?” she asked. The only time Stacey had ever felt anyone cum inside her was when she had Marcy’s cute little cock, and she was sure the girl had just taken more than she could ever give.
“F-full…” the little rodent replied, looking awfully bashful.
“Mhhh, plenty of time for me to get a towel or something. You’re gonna be a mess…” she husked, bringing her lips in for another kiss, the sibling’s tongues twining as Marcy remained tied to the kit who’d just finished seeding her snug little rump. Nathan leaned in when they broke their kiss, eyes half-closed and lips pursed as he hoped to steal a kiss from Marcy’s big sister. He looked cute, but still wound up with a finger pressed to his muzzle instead of a young woman’s lips.
“Sorry sweetie. You’re cute, but I’m not really into boys. Oooh, but I bet Natalie would be sexy as hell…” she said, envisioning a vixen…
