But She Wasn’t In Heat!

Lacey stared at herself in the mirror.

Don’t screw this up, girl, she muttered.

For as easily as she had gotten into the best university in town, there was still the matter of joining the premier sorority, which had proved to be even harder.

The cheetah brushed her fingers through her purple hair. Maybe dying it had been a mistake. It looked good, but she had sort of unintentionally upstaged the sorority girls by looking too good. That was probably why she had failed the first challenge. It had been to flirt with as many men as possible in one night, and each one that reciprocated counted. They’d had a girl from the sorority with them to make sure the pledges did their challenges, and Lacey had made the mistake of scoring higher than her instead of just barely under.

It was the purple hair, she told herself. Too much. Either that, or it was her heavy breasts, which were also considerably bigger than the recruiter’s. But there wasn’t much she could do about either. She couldn’t bleach the color out of her hair without totally ruining her look, and she couldn’t shrink her tits. Nor did she want to; she was proud of both. But she was a chronic overachiever that clearly didn’t understand these hazing rituals where she was meant to “fail,” at least in comparison to the established queen bees of the sorority. Typically universities didn’t have the established members compete with the pledges, but of course her chose university just had to be different.

She stared into her own yellow eyes.

So, yeah, we know the problem. Now stop doing that, Lacey told herself.

Then there was the second challenge. That one should have been so easy. It was a simple drinking contest that she was supposed to lose. Naturally. She was short and slender compared to the sorority girl that they’d been “competing” with. Not that that girl had been particularly big either, but bigger. So, it should’ve been a slam dunk; she’d drink herself silly and end up embarrassing herself. A hazing ritual. Simple. And you still screwed it up.

How? Well, she hadn’t figured out yet that the whole point was to lose. They told her that afterwards. And so, while everyone else had drunk entirely too much, she, with her naturally higher tolerance, had also treated it like a normal night out, having a bit of water between each drink. Meanwhile, the sorority girl had grossly underestimated how much of a difference simple genetics could make and ended up so drunk that she was face-down on the bar and cut off by the bartenders for the rest of the night. Worse yet, Lacey and the others had to carry her home.

Oh, sure, everyone had failed that one, but that didn’t make it any less bothersome that she had failed it. She muttered quietly to herself about how the next time they drank, she’d just grab a bottle and not stop before it was empty, no matter what it took.

That wouldn't be the next challenge, though. It’d be her very last chance to join. Sure, not getting to join wasn’t technically the end of the world, but the cheetah had been rather shy in high school, and now, she desperately wanted the chance to do new things with all the sorority girls in college.

What was the next challenge? She wasn’t entirely sure. She just knew it involved the sorority’s fundraising car wash, which really was little more than a couple of busty girls with buckets and sponges cleaning cars as suggestively as possible. Yeah, the usual chestnut, really. Only there was supposed to be an additional “punishment” during this one, as levied upon her by the sorority for repeatedly upstaging their members.

She didn’t know what the punishment was, but knowing what the girls got up to, it was probably sex. She had very little experience with that, bar for a few painful attempts with her ex-boyfriend, and for once, that’d be an advantage. If there was some sort of sexual contest, she would lose for sure, and it’d be embarrassing, and yada-yada-yada, that would hopefully satisfy the sorority as hazing enough.

Lacey wasn’t in heat or anything, as far as she was aware, though she had felt a little flushed, tingly, and damp through the last few days. Enough so to make the idea seem a little appealing. University was supposed to be time you did all that crazy stuff, anyway. Lacey checked her calendar just to make sure. Technically, it was time for her to go into heat again, but she remembered exactly how it had felt the last time. She’d practically been climbing up the walls with how horny she was.

So, this wasn’t it yet, or at least, she didn’t think so. That was as much as she decided to think about it, because if the challenge was sex and she ended up worrying about pregnancy, she’d fail again, and that’d be that for her chances of joining the damn sorority. Like a third of the girls were pregnant anyway and managing just fine.

Okay, showtime. Go do your thing, Lacey tried to psych herself up, giving herself a double thumbs up in the mirror but then switching to finger guns, as it fit the vibe she was trying to give off better.

With that, the cheetah left the bathroom. She still felt underdressed with only a tight bikini top and shorts, but that was the “uniform” required for the car wash, and so, everyone else was wearing the same.

Outside, the sorority sisters were waiting for her.

“Okay, newbie, you know how this goes, right?” a wolf asked her, with a grin wide enough to swallow men whole.

“Um, I think so,” Lacey replied. “We wait for a guy to pull up and then wash his car.”

“Yeah, that’s what we do, but you are on special duty today. Remember how that goes?” the wolf prodded, her voice both playful and mean. “You clean cars until someone orders our Special Service Car Wash, and then…”

Oh, right. Yeah, it was sex. The idea of “servicing” a complete stranger was oddly exciting for the cheetah, though she wasn’t sure she’d actually be good enough to leave them satisfied. Then again, considering her ex, usually all men needed was a pussy, and they’d do the rest themselves. A pair of tits helped, too.

“Then I guess I… ‘service’ them?” she asked, hesitating a little. For all she knew, it could be another trick question. But not this time.

“Yeah. Well, you’re gonna service one person for this challenge. Don’t worry, we’re all kinda loose in this sorority,” the wolf laughed. “God, I must’ve taken like…”

She trailed off, counting on her fingers until she ran out.

“Well, more cocks than I have fingers, at least. So don’t be a prude. Remember, it’s your last chance to get in. If you fuck this one up, no more chances, you get to join some of the other losers in their little loser-clubs,” she pointed out.

Thankfully, while she wasn’t very experienced, the cheetah was hardly a prude. She had always had a kind of laissez-faire attitude about it all. Though there was another thing that popped up in her mind at the wolf’s lascivious verbal prodding.

“Can we use condoms?” she asked.

The wolf cocked an eyebrow, looking at Lacey as if she was an idiot. And in a way, she was, at least on this matter. “I mean, fuck yes you can. Unless you want to get knocked up in a hurry. Been there, by the way, wouldn’t recommend. Being pregnant is nowhere near as fun as being knocked up is.”

Together, they walked through the campus and to the improvised little car wash area that the society had set up. Lacey found herself shivering, the air bitterly cold this morning, and in a way – despite what it actually implied – the thought of “working” indoors was rather pleasant. Especially given that she was still wearing a bikini top. The others would have to stand outside in the cold and probably get wet while she’d be indoors… well, she’d also be getting wet, but hopefully in a much warmer and more intimate way.

The “car wash” consisted of little more than a tent pitched in gravel, a shelf that held all the necessary cleaning products, and a hose connected to the university’s water mains. It was very much bare-bones, but people didn’t really come here just to have their cars washed, after all. They came because of who was washing them, and quite often, for the secretive “special service”.

It was, effectively, prostitution, but for the charitable cause of funding the sorority’s parties. And so, nobody, least of all the men who used the service, wanted to report it as such.

The wolf – Lacey had the faintest thought that her name was Samantha, but didn’t dare ask to clarify – then showed her the nearby tool shed. The interior of it had, thankfully, been refurbished into something a little less dirty and oily than a tool shed might be expected to be, and it was heated, which was a welcome escape from the rather chilly early morning air.

There was a mattress, battered but clean, on the floor, a few boxes of condoms and lube on the shelves, and all in all, it wasn’t too unpleasant a place for that kind of work.

“So yeah, this is where you’ll be putting that pussy of yours to work,” the wolf commented. “I think our second customer of the game has ordered the special service, so you might as well stay here and get comfortable while the rest of us freeze our tits off.”

She left Lacey there to adjust, sighing as she got to work on the first car, a plain sedan without much dirt on it. Sometimes, Samantha missed being the new girl. God knows it was more fun than having to actually wash cars and pretending to be extremely horny about it. At least it was a quick job of smushing her tits into the windshield and a little grinding between sponge and hose.

The second car, though, was an enormous pick-up truck, absolutely caked in dirt. This would be Vince, just a year her senior, the wolf who had ordered the special service. His fur was charcoal-black, and Samantha felt a rather honest twinge of jealousy as he stepped out of his vehicle with a little grin on his face. He looked toned enough to invite home, at least for one night.

But today, that’d be Lacey’s job. So, Samantha offered Vince her friendliest smile, a small, excited bounce that made her tits jiggle, and then directed him towards the shed.

In the shed, Lacey was waiting. She didn’t exactly know what she was expected to do, and so, she went with the most obvious, pulling off her bikini top and then her shorts as well. If whoever it was wanted her to strip, they should’ve told her that, she reasoned, and then laid down on the mattress to await her lover, striking a pose that she found to be sensual enough with her hips pushed up just a little, and her arm pushing her breasts out in a similar way.

She didn’t have much idea of what she was doing, but there was that familiar arousal anyway, the warm glow in her belly and the tingling dampness of her pussy which made her a little more confident. It wasn’t a heat, so it had to just be what feeling sexy was like, right? Maybe she’d actually get to have some good sex for once. Someone who frequented this place would surely have picked up a trick or two along the way.

Soon enough, the door opened, and Vince stepped in. Lacey let out a little gasp as she saw the handsome wolf, immediately excited about their “playtime”.

“Hello, handsome,” she exclaimed, putting on her best porn star impression. “You wanted the special service?”

“Mhm. I haven’t seen you here before, though. New girl?” Vince asked with a broad grin. He liked the idea of breaking someone else in, and was in fact already getting hard underneath his jeans.

“Yeah, it’s a challenge to join the sorority,” Lacey admitted. “But with how sexy you are, I don't think it's a challenge at all."

“Heh, well, let’s see what you can do, then. Why don’t you get me ready?” he suggested, just barely nodding down and towards his pants. “Wouldn’t want to get any dirt in your workplace.”

Oh, he wanted her to strip him. Lacey was immediately filled with excitement, not totally unlike unwrapping a Christmas present, as she rose to her knees and made her way to Vince, who was standing at the edge of the mattress. Yet, she still found her heartbeat quickening as she neared him.

Was she really going to do this? To sell her body just to be a member of a sorority that encouraged it? Well, it was a little degrading, but at the same time, she did really want to be a member.

So yes, she was going to do this. So stop hesitating and just go for it, he’ll probably be happy just fucking you at his own pace.

Gingerly, and with her hands trembling only slightly, Lacey reached up to unbutton the wolf’s jeans. Up this close, she could smell his arousal, a musky but clean kind of spiciness that she immediately thought of as virile male. It wasn’t unpleasant at all. In fact, Lacey found herself rather enjoying it, as if her sense of smell was a little more sensitive than on the average day.

Lacey dug her fingers into the waist of the wolf’s jeans, and from there, his boxers, too. She tugged them down, and his half-hard cock sprung out, smacking her across the muzzle, drawing a quick, surprised chirp from her.

“What can I say? It gets like that when with an attractive woman like yourself,” Vince chuckled at her startlement.

Lacey sat there, staring at Vince’s cock resting against her snout. It was warm, firm – swelling even as she paused – and luscious. She immediately felt the urge to wrap her lips around it, and somehow, the scenario excited her enough that she didn’t hesitate. Lacey let her whiskers brush over his thick, imposing length as she moved to kiss the very tip, where a warm droplet of precum smeared over her plump lips.

Without needing to be told, she stuck her tongue out and gave him a little lick around and under the tapered glans. It was Vince’s turn to shudder as her raspy tongue sent little jolts of pleasure through him, instinctively making him throb as another little splatter of precum splashed over the cheetah’s nose.

“Aren’t you -rrrf- an eager girl?” he rumbled. “The girl they had last year really needed some coaxing. You sure you’re not in heat?”

Of course she wasn’t in heat. And they’d use condoms, anyway. Lacey didn’t dignify that question with an answer, quite unaware of what was happening inside her body as she licked more firmly, before letting her lips wrap around his shaft and suckling gently, still a little unsure of what she was actually doing, but remembering that her clumsy ex had rather liked it when she did that, engulfing his cock with her mouth while applying the slightest suction. Sure enough, Vince shuddered again, but unlike her ex, he was far from cumming instantly.

Instead, he leisurely rocked his hips back and forth, letting the cheetah get used to having his cock in her mouth. He wasn’t planning to finish in there, but it was the perfect foreplay, especially when Lacey decided to cradle and cup his heavy balls. Why she did that, she couldn’t say, but it just felt right to sensually gauge her partner’s potential virility. Well, on a subconscious level, it did, with her instincts taking over more and more from her conscious mind, the latter not recognizing any of the signs that she might indeed be rather fertile.

But even the tingles of that worry were easily swept under the rug by the fact that they’d use a condom. Several condoms, if it came to it. There was no risk, one way or another. No real risk, anyway.

He let her enjoy his cock for a little longer. Not that he wasn’t enjoying it just about equally despite her clumsiness at sucking a cock; every little lick and squeeze of her lips still had Vince readily leaking into her mouth, until he finally stopped her, pushing her head away.

“I think it’s time for the main course. Well, the first main course,” he grinned.

“Can we use a condom?” Lacey asked, licking her lips.

Vince reached into one of the open boxes on the shelves and pulled one out, before tossing it to Lacey, who caught it midair with her feline reflexes.

“Sure, as long as you put it on. Full service, right?” he smiled.

Lacey tore the wrapper open with a little bit of urgency, careful not to let her claws scratch anything. For the briefest of moments, she felt the urge to just go without it, but dismissed that thought as a foolish, overexcited fantasy. Yet as she moved to roll the condom onto Vince’s cock, he stopped her again with a head between her ears.

His voice was a demanding growl when he spoke again. “Not with your hands, dear. Put that mouth to use.”

Mouth? That would be a bit of a challenge. But Lacey agreed; she was at the point where she really wanted the wolf’s cock inside her, and not only because it was her ticket into the damned sorority. She grabbed the condom with her mouth – noting that it tasted like very artificial fruit, evidently a flavored kind of condom, which make her feel a little naughtier yet – and then struggled to push it into Vince’s cock while keeping her teeth away from both the rubber and his shaft.

It wasn’t easy. Rather, the total opposite. The cheetah struggled to roll it out with just her tongue and lips, but Vince was patient enough to let her struggle, not to mention that her “struggling” felt rather exquisite on his rock-hard cock. Eventually, Lacey managed, if only barely, to start rolling it out, forcing her mouth deeper on the wolf’s cock with each tiny part of an inch that she unrolled, until his tip touched the back of her throat. Thankfully, with how horny she was, her gag reflex was suppressed enough that she found it rather exciting too. Thankfully, Vince’s knot was only slightly swollen, which meant that she managed to get it all the way down to his base, where the knot, once it swelled, would keep it in place.

Finally, and proudly, she pulled off, but without noticing, she closed her mouth just the slightest bit too early, and one of her sharp canines scratched the very tip of the condom, leaving a hole so tiny that it was barely noticeable without a close inspection. A close inspection that she, still being rather new to the whole sex thing – no matter how much she desired it – didn’t really know to do. And neither did Vince. Though more experienced, the wolf was hardly a veteran, nor was he one to think too much about possible consequences.

She looked up at the handsome wolf lustily, before leaning in again to kiss the tip of his condom-covered – and safe, or so she thought – cock, getting one last chance to notice the tiny rip in the latex. She didn’t, of course, because she wasn’t expecting it.

“I think I’ll want you in, hm, let’s say downward dog,” Vince grinned.

“Um, what’s… that?” Lacey asked. She was totally up for experimenting with positions, and while downward dog sounded a little like plain old doggystyle, she had never heard the term before. A yoga position, maybe? Thankfully, the cheetah was flexible, though not terribly well trained.

Vince tapped a few words on his phone and then showed her a picture of a serval getting fucked in that position. Oh. It looked a little challenging, but by now, Lacey’s pussy was itching for attention in a way that felt almost but not quite like being in heat. Not to mention the rivulets of her juices that were matting her thighs after sucking on the wolf’s cock for a while. And so, she decided to try. She had to please their handsome customer to join the sorority, after all.

Lacey turned around onto her stomach and then, leaving her chest flat against the mattress, scooted her hips up until he was standing almost on her tippytoes, with her vulnerable – and unknowingly fertile – pussy proudly and eagerly presented for the wolf.

“Like… that? I’m not sure if I can stay like this for long,” she squeaked.

“Oh, I’ll help you,” Vince laughed, and then grabbed her hips as he stepped onto the mattress, helping hold her up without straining her legs too much. “Mmh, what a perfect pussy you have. I’m gonna claim every inch of it.”

Lacey blushed at his lewd words, but they only turned her on more, knowing that the wolf approved of that damp, puffy slit of hers. Especially with how badly she found herself needing to get it stuffed and stuffed hard.

Then, she felt his cock, hot even through the protective rubber, against her lips.

“Soaking wet for me too,” Vince continued, teasing her with words just as his cock teased her entrance. “They really picked the right girl for the job.”

“Fuck me, please,” Lacey managed to reply, not quite as used to dirty talk as Vince was, but still wanting to contribute. Her sex clenched against his shaft, and then clenched again as he began to push inside, excruciatingly slowly. She was tight as a virgin – it had been a long time since she technically lost her virginity – but her sopping wet pussy offered no real resistance beyond that tightness.

He was big, too. Much bigger than her ex. And he didn’t just thrust into her. Vince, while continuing to support her with one hand, reached around with the other to fondle her clit, teasing the stiff little nub with light, feathery flicks. Lacey’s claws dug into the mattress as shivers shot through her body, and her silken inner muscles clamping down around the wolf’s cock firmly once again.

What neither of them knew or could feel – yet, at any rate – was that the sheer tightness of Lacey’s cunt combined with the size of Vince’s cock was making that little, barely noticeable hole that might have still protected her womb from receiving a warm, fresh load of cum widen_,_ stretched by the friction just as her pussy was stretched by Vince’s cock.

“F-fuck, I can already tell we’re gonna have to go a few times,” Vince huffed, only halfway into her, but sliding deeper into that inviting wet heat by the second. “Dunno how long I’ll last on the first go if you’re going to be this tight.”

Had she been a little looser, the condom might’ve managed to protect her. If she didn’t clench so hard, it might’ve captured at least some of the wolf’s cum. But she didn’t know what her body was unintentionally doing, simply enjoying that feeling of being filled in a very “safe” way. Finally, they both gasped in pleasure as Vince hilted in her, buried all the way down to the base of his cock inside the most intimate part of her body.

It felt blissful. It felt right. They were both horny late teenagers, just a little over eighteen. This was what she was meant to be doing, Lacey realized, and it was an eye-opening experience. With how wet she was, just being filled like that felt amazing, far better than when her ex had fucked her dry pussy. And all it had taken was a little foreplay to get her there.

“Ready?” Vince asked. “I’m gonna make you a proper woman.”

“Please,” Lacey whined. She fought the urge to push back on the wolf’s cock at first, but then, realized that there was no reason to resist. She was already full of cock; it wasn’t as if there was anything wrong with enjoying it. And so, she pushed back with a moan, almost falling over, but letting out another needy moan as Vince’s lupine cock lodged even deeper inside her.

“Just let me do the work,” he chuckled. And then, he began to thrust, and Lacey immediately saw stars. The exquisite wet friction was making her fur stand on end, flooding her mind with so much pleasure that she was immediately left trembling, catching herself drooling on the mattress as Vince figured out a steady rhythm, adjusting it with each second to keep her whimpering.

With each thrust, the hole in condom widened, from a little scratch to the point where, when Vince’s cock bumped against Lacey’s cervix, it tore entirely, leaving his very tip exposed. There wasn’t any immediate change in how the sex felt, but it did mean that each time the wolf squirted more hot precum, it splattered into her defenseless pussy rather than being caught by the condom, just like his cum would if neither of them noticed. Their mating grew slicker and wetter yet, but that was easily explained away by how aroused Lacey was, her sex drenched and the cheetah moaning and yowling incoherently, blissfully unaware that there was a leak.

And that leak kept growing. As Vince began to thrust more aggressively, the condom slipped further down, the force of his rutting leaving it in tatters and the head of his cock, the dangerous cum-slit that’d inseminate her left entirely bare. In just a few minutes, what little remained of the latex was bunched up around the base of his cock, and had he looked, he would’ve noticed. But he was far too focused on the pleasure of it, his eyes screwed shut as he fought the urge to just cum right away.

But it was beginning to feel different. Vince noticed that, but he didn’t put two and two together, instead just chalking it up to getting closer and closer to his impending orgasm. Or maybe the condom was just one of those that made if more pleasurable for the male. Lacey felt warmer around him, even wetter, and the pleasure- oh, gods, the pleasure, it felt even better than it had before. As if she was massaging every inch of him with every pleasurable, rippling squeeze of her inner muscles. Of course, in reality, all of that was because he was now inadvertently obeying all his biological urges, rutting into a woman unprotected with his body preparing to not just cum, but to breed her.

Lacey felt it too, how Vince suddenly felt even warmer inside her. How she could feel every detail of that beautiful cock. She had no proper experiences to compare it to, and as such, rather than asking Vince to stop and check that the condom was still intact, she moaned out with pleasure, assuming that this was just how good sex felt, naturally leaving her hypersensitive down there, rather than the real natural reaction to a bare cock readying itself to pump her full of baby-making seed.

As pleasant as it was, though, her legs were starting to give in. It felt like she was just barely able to keep her knees from buckling under the force of Vince’s thrusts and the pleasure they made surge through her body. And course, the fact that she was in such an acrobatic position to begin with.

“K-keep fucking me, but… maybe I could like, lay down?” she panted, the thought of letting her legs relax seeming almost as good as the feeling of a thick lupine cock claiming her pussy.

“You look so sexy like this, though,” Vince laughed. But it wouldn’t be much fun if the cheetah was straining too much to cum. “Fine. Lay down.”

That would’ve been another moment when he could have noticed that the condom was little more than useless tattered latex at that point, had he pulled out. But he didn’t, too enamored by the feeling of the cheetah’s pussy squeezing around him. He never wanted to pull out, even knowing that he’d have to eventually, and instead chose to remain pressed against the cheetah with his half-swollen knot kissing her folds as she laid down into a much more comfortable and relaxed position, her ass only slightly pushed up to make it easier for the wolf to fuck her.

And oh, gods, did she ever want him to keep fucking her, as hard as he could.

With a rumbling growl, Vince’s teeth just barely scraped the nape of her neck, gnawing ever so gently on her scruff. It wasn’t time for a mating bite yet, but it felt like the right thing to do. He always liked biting his partners when he came, and Lacey certainly didn’t seem to mind the wordless suggestion with how she shivered, even craning her neck to give the wolf better access to all of her most vulnerable spots.

And then he kept thrusting, pounding the cheetah into the mattress, both of them racing towards a shuddering mutual climax. By some miracle, Vince had actually managed to last to the point where Lacey was close to her climax as well, as very obviously indicated by how she was clenching around him hard, and her stuttering breath. But he wouldn’t last much longer, and he knew that.

“Rrf. I’m getting close. Want me to knot you?” the wolf rumbled. He desperately wanted to do it, but he also wanted to make sure that the cheetah didn’t have somewhere else to be. College could be busy, after all – or there might be someone else wanting the Special Service – and he was half expecting a “no” until the cheetah managed to reply, between needy moans and gasps.

“Yes!” she exclaimed, voice dripping with lust. “Stuff that big wolf-knot into my pussy!”

Normally, getting tied wasn’t exactly advisable unless one wanted to get pregnant. But there was no risk that she knew of, and so Lacey begged for it, half in words and half physically, pushing her ass back into the wolf’s thrusts and moaning as his knot threatened to stretch her wide open. She had always fantasized about it.

“Here it comes, kitty,” Vince growled, and pushed against those lips hard, the cat barely feeling any less tight than she had in the first moment.

Lacey groaned at the sheer stretching of the wolf’s knot pressing against her slowly yielding entrance. Had she known anything about the situation beyond how it felt, she would’ve squirmed to get away. Instead, she sealed her fate by squirming back against him.

Pop. Suddenly that lupine knot was inside her, tying the two together. He gave it a tug to make sure he was stuck, and together, the two moaned like wild animals at the sensation. Lacey found herself loving it, making a mental note to play with more wolves when time allowed, but the pleasure was quickly followed by a sudden jolt of pain as the depth left his tip pressing firmly against her battered cervix. The slightest bit of him slipped inside her very womb, but as he firmly bit down on the feline’s neck at the same time, it only enhanced the pleasure, and in a heartbeat, pushed her over the edge.

She let out a wheezing gasp, her mouth falling open and her eyes rolling back as she experienced the strongest orgasm of her life. Her ex had never managed to give her one at all, and so in that moment, her inexperienced mind was completely overwhelmed. Her legs went stiff, her back arched, and her toes curled as the first wave of pleasure shot through her, leaving her trying and failing to breathe between each earthquake-like wave of bliss.

Those rapid, rhythmic contractions quickly had Vince crashing into his own orgasm too. He hadn’t cum for a month or so – he didn’t like masturbating and hadn’t had any luck with partners recently – and between Lacey’s heat and her clenching, it was all he could take. His balls tightened, preparing to unleash their cargo, almost as if his body somehow knew to put his everything into this, that there was nothing to stop his swimmers from reaching her eggs. He grasped the cheetah’s waist tightly, threw his head back, and howled out in triumph as he came, throbbing hard inside her.

With the very first throb, their fates were inevitably sealed. A thick rope of pent-up cum erupted from his cock, half splattering against her bruised cervix and half injected directly through it, into her fertile womb. Though neither of them knew it was happening, the sensation was mutually blissful, nature itself sharpening their orgasms into something truly overwhelming, the well-deserved reward for unprotected sex. Lacey could only shudder, her head high in the clouds and her pussy still milking Vince’s cock for all it was worth, each spasming contraction teasing more cum out of him and pulling it deeper into her body where it belonged. Vince in made no sound except breathy growls as his entire world narrowed down on that vice-like squeezing, with the wolf grinding against her in a desperate bid to sink even deeper into her. It felt like white-hot heaven, a perfect and messy union of the kind that’d almost certainly result in her belly swelling.

He slumped down on top of her, the orgasm having sapped what little strength he had left, tongue lolling out just like hers was as his cock kept pumping, every drop of his dangerous cum safely sealed inside her by his swollen knot.

Lacey’s climax ebbed, leaving her head fuzzy and tingly, the cheetah basking, wallowing in that sweet post-coital bliss of having her womb bathed in virile seed. She could still feel Vince’s cock jerking inside her, his heavy balls pressed almost flush against her slit, and even those little sensations became so deeply erotic that she didn’t ever want the moment to end.

She snuck her hands underneath herself, touching her belly where her womb was subconsciously as she savored the feeling of- the tingling feeling of- warm, plentiful cum soaking into her?

It really felt as if he was cumming inside her. She tried not to think about it. Condoms didn’t just break, and she wanted to keep enjoying the moment for a little longer, but it became impossible to ignore, and a look of panic dawned on her face as she realized that the wolf was actually inseminating her, that the condom must have failed, and that her body was happily taking every drop he pumped into her.

“Get off! The condom broke!” she yelled, and it took Vince, who was still far away in a blissful haze, almost a full minute before the cheetah’s yelling actually got through to him.

His eyes snapped open. “Pull out! You’re cumming inside me!” she shouted, trying to squirm and even push him off. With a grunt, the wolf tried, only to remember that his knot still held the two together as both winced in pain at the attempt. He tried again, with the same result, the pain mercifully dulled quickly by the embers of his climax. Like all canines, he was still cumming, and would be for as long as they remained tied.

“I can’t,” he growled, between gritted teeth. “Fucking knot. Sorry.”

Lacey slumped down, defeated, screaming into the mattress with annoyance. It wasn’t the wolf’s fault that the condom had broken, she told herself. There was no point in getting angry at him. And she wasn’t in heat anyway, so ultimately there’d be no damage done. Left with no choice, the cheetah could only continue to, now unwillingly, enjoy the feeling of Vince’s cock twitching inside her, and the wolf, though deeply frustrated, equally couldn’t say that he didn’t love the feeling of what was happening. It was impossible for any straight male not to enjoy cumming inside a totally unprotected pussy, after all, another of biology’s little tricks to ensure reproduction, as it just had.

She sighed.

“Well, I guess it’s okay. I’m not in heat or anything,” Lacey finally said. “What’s your name, anyway?”

They introduced themselves to each other in a rather unusual position, still joined together by both her tightness and his knot. Eventually, the frustration had gotten to the point where they could, somewhat begrudgingly, engage in a little small talk about college life to pass the time after the pleasure had faded and left only a relaxed sense of satisfaction. An hour later or so, Vince had deflated enough that he could feel the cum beginning to leak out of the cheetah, something that Lacey was very aware of. Not that there was any rush, at this point; she had looped around from being extremely into the moment, to angry, to frustrated, to simply enjoying it again. In the end, just like Vince, it was impossible for her not to enjoy the feeling of her unknown heat being sated as the wolf’s sperm found her eggs.

Vince finally pulled out. He looked down at their messy union, and found that indeed, just as they had feared, Lacey was slowly oozing with his cum. He groaned with annoyance, perfectly aware of what it might lead to, and equally angry at himself for not noticing. He turned around to leave, if only so he wouldn’t end up yelling at Lacey – neither of them was at fault whatsoever, after all – but to his surprise, Lacey stopped him.

He turned around, swallowing his frustration, and looked at her. She did look pretty damn sexy laying there like that, with her legs spread and oozing. Despite the natural annoyance of having become one of the tiny fraction of people who experienced condom failures, the sight filled with chest with a kind of primal pride. He had, after all, performed what one might see as the ultimate masculine duty of seeding his mate.

“Y-you know, you could just fuck me again, I mean…” Lacey started, hesitating a little before reaching down rub at her well-used pussy. She was shocked, infuriated, and angry, but at the same time, she felt the same flushing arousal as Vince did. The damage was already done, so there was no real reason to not indulge a little more, was there? “It’s not like it’ll make any difference if you cum inside me twice.”

Well, she was certainly right about that one. They might as well enjoy the moment a little longer, right?

“In for a penny, in for a… pounding?” Lacey giggled. She still felt a little lust-drunk despite all the fear and anxiety. But in the end, she wasn’t in heat, or so she told herself, so what was the worst that could really happen?

Vince agreed. With a growl, he was on top of her again, grabbing her thighs tight enough to leave bruises as he thrust his rapidly hardening cock into her rather sloppy sex, much to Lacey’s delight. She moaned out shamelessly, pushing whatever worries she had out of her mind, and wrapped her legs around Vince’s hips to pull him deeper, rather instinctively eager to experience a round of full, unprotected sex. It just felt so much better to not have to worry about the condom, and the warm, slick feeling of his now intentionally uncovered cock inside her was just intoxicating.

What was the worst that could happen, indeed?

A few months after their encounter, Lacey found herself nauseous. She didn’t think much about it; sometimes, things like nausea just happened, and it wasn’t as if she could be pregnant. Sure, the condom had failed, and then she had been inseminated again without anything in the way, but she hadn’t been in heat.

Right?

The thought, though, lodged itself into her mind like a splinter, as much as she tried not to worry about it. In the end, she started to search for more information that she hadn’t picked up in sex ed. Heat was always supposed to be an overwhelming experience of need, that’s what they’d always told her, and it was how it always had been for her, too.

And yet, she had a growing suspicion that something was, in fact, terribly wrong. It was to the point that she went to see a doctor about it the moment that she started putting on weight.

“But I can’t be pregnant, I wasn’t in heat,” she protested, as the doctor began to look her over.

“What makes you say that?” he asked.

“Well, I wasn’t really feeling like… the need, the kind of thing I usually feel when it hits,” Lacey explained, and the doctor shook his head.

“Silent heat, maybe. They aren’t always obvious,” he sighed. “But given that it was your fertile period and you had unprotected sex… I’ll still give you a test, but it’s rather a foregone conclusion at this point.”

A “silent heat,” it turned out, was much like what other species experienced they ovulated. She had been hornier than usual, and she still remembered the tingling and desire. How hot she had been feeling. And then, not suspecting anything and breaking a condom while at it, she had taken not one, but two loads of potent, virile cum deep into her treacherous pussy.

When the doctor eventually told her what the test results showed, Lacey, still shocked, realized that she didn’t even know Vince’s full name. And it couldn’t be anyone else either. She hadn’t had sex with anyone else since then, and she’d never had unprotected sex with anyone else.

Later yet, thanks to classes and life in general, Vince still hadn’t seen Lacey again, not even at the sorority’s other fundraisers despite her now being a full member. He found himself missing her. Not only the wild sex that they’d had, but he would’ve been lying if he said he didn’t have a little crush on the cheetah, hoping that they’d at least end up running into each other again .

A little after that, he was at the campus grocery store picking up whatever he was going to eat for the week. Vince missed juicy steaks, but those were almost impossible to prepare correctly in the dorms, and so he was contemplating steak-flavored ramen as someone bumped into him.

“For fuck’s sake, maybe watch where you’re going?” he barked out. “You’re gonna break the noodles.”

And then, after a quick look at the offender, he realized it was a cheetah. A pregnant, female cheetah. It took his brain a second to connect the dots. Lacey! She looked back at him with equal surprise before the two hugged, with her heavy belly pressing against him.

Soon the two were at the campus park, sitting on a bench together and catching up on everything that had happened. As much fun as it was, there was a burning question on Vince’s mind, and it wasn’t until a lull in the conversation that he finally dared to bring it up.

“…so, whose is it?” he asked, assuming that it couldn’t possibly be his given that Lacey hadn’t been in heat when they’d fucked. He felt a rather painful pang of jealousy at the thought, at least until Lacey gently grabbed his hand and rested it on her gravid belly, and Vince’s heart skipped a beat, and then another, from anxiety and pride respectively.

“It’s yours,” she smiled.
