#221 of Commissions

Commission for IrvingWrites!

A four-woman project to solve the colony's reproductive issues proves maybe slightly less than scientific when their subject proves irresistible. The feline species they've captured might be several centuries behind, technology wise, but he knows what those researchers need. What's supposed to be an experiment quickly devolves into some wild, relentless breeding - and the subject is ready to satisfy every one of his captors!

Contains: musk, pheromones, breeding, impregnation, femdom, hyper cocks, hyper cum, inflation, and more!


After population growth had fallen to critically low levels on their home planet, the team of four felines had taken up the mantle of finding a solution to their woes. Male fertility was dropping in their mostly-female society. No matter how fertile and receptive the women got, pregnancies were still concerningly rare. After much investigation the decision came from up high that they were going to have to break some galactic rules. Contacting a civilization that had yet to develop space travel was supposed to be a big no-no, which meant that their mission was officially unofficial. They were on their own out there on an alien planet, one populated by a species much like their own. At first glance, the alien felines seemed like they might have been all-female, but it was just that males had particularly slender, feminine forms. If initial probes were correct, they were the precise answer to all their worries back on the home planet. With the help of Val, their security expert, they'd laid a trap and lured one of the roaming hunters. He hardly seemed to mind.

The subject seemed stable and relatively docile, so far. He paced back and forth in his holding chamber without any visible sign of agitation. Maybe some confusion. He tapped on the glass now and then but made no attempts at escape. That came as a surprise to the four of them. Val had been ready with all sorts of non-lethal tools in case of violence, but even coming from such a relatively primitive society of hunters and gatherers, the alien feline was quick to accept the change in circumstances. He gazed out at the research team with an expression like curiosity, and paced a little as he waited for them to address him. He looked something like a lion at first glance, with a tawny pelt and a head of light hair framing his slim, handsome features, but he didn't quite fit the description. His narrow shoulders and broad hips spoke of a graceful, soft individual, but there was plenty of lean muscular tone to support his wild lifestyle. Of course, those finer features were very much the second thing they all noticed. The first swung freely between his legs, impossible to fully conceal beneath his loincloth. If any of them had doubts about coming there to conduct fertility research, they were assuaged by the sight of that massive tool bulging there beneath those leather skins, soft yet already so much larger than the gear of any men they'd ever met.

Their lead researcher and boss was one such example of those exceptionally fertile-looking women. Cassandra observed him while she dictated her notes to a nearby machine. The enormously endowed tigress was an exceptionally shapely example of her species. The years gone by had only brought her greater blessings. A tremendous bust bulged beneath her lab coat, while wide, matronly hips complimented an overall curvaceous shape that was common among the women of her planet. Despite her figure, she'd never been a mother, nor had any of the other staff she brought with her to that planet. It was a relative skeleton crew given the secret nature of the project. Having just two researchers, a security expert, and a pilot meant plenty of multitasking and tending to duties that weren't quite within the realm of their job description. None of them complained when the fate of their whole species was on the line. Though spending weeks isolated out there in their research base did brew a certain desperation that, thus far, the four of them had managed to keep hidden. The subject wasn't helping.

"I suppose we'll need a name for him, unless we intend to call him Subject for the duration of our work," said the lioness among them.

The assistant researcher was the bustiest of the four, which was a competitive field. Andi didn't even bother buttoning her lab coat. It simply couldn't compete with a chest the size of hers, and two giant beachball tits that beat out her head for sheer size. They could be a burden at the best of times, but the time spent without any sort of intimate touch was making them extra tender. Even a slight rub against the inner fabric of her lacy bra was enough to make her flinch. A growing need was warming her all over just to look at that slim, hung male gazing back at her. Only Cassandra's words roused her from her fixation.

"Hm. Perhaps it isn't wise to get too attached to him. We're simply borrowing him, after all. A quick memory wipe and he'll be back among his people without disturbing their society as a whole. Though ..." The tigress tapped her black lower lip with a fingertip. "For convenience's sake, I'm sure John will suffice. As in Doe."

"Do you think he understands us?" came the curious voice of the snow leopard, their pilot.

As the youngest of the four, Belle was also the slimmest. She didn't quite possess the same extraordinary curves as her colleagues, but the silver-furred cat was plenty soft and just as attractive, or so she liked to think. Scanning over the frame of the captive male made her bite her lower lip now and then. Despite her inviting features, it had been so long for her that she'd found any sort of release, even long before departing for their journey. Some small part of her hoped that coming along for this mission might mean finally finding what she so badly needed, along with saving society as a whole. Though how exactly she expected to accomplish that, she really didn't know. Maybe the opportunity would simply find her. Cassandra didn't look in her direction when she answered, though it wasn't out of any sort of disrespect. She simply was far too focused.

"Well, that might be the case, if he could hear us. No sound's getting through his enclosure." She paused and tapped her lip again. "I suppose we ought to open it and see if communication is possible."

"Right. I'm loaded and ready, if the need arises," the nearby pantheress gruffly said. As the sole security expert on staff, all responsibility came down to Valentina - Val - if something went wrong. Judging by her sleek, muscular form, she was ready for it. Though that wasn't to say she wasn't similarly shaped as the other busty, exceptionally curvy women she worked to protect.

"I would much prefer if we didn't resort to that unless absolutely necessary," Cassandra urged. "But stand ready nonetheless. I'm going to release him ... now."

A whirring sound came as the enclosure slid up towards the ceiling, leaving the specimen, John, blinking in surprise. He still didn't appear to be alarmed or aggressive. If they didn't know better, they might have thought Val had drugged him in the process of capturing him, but she wouldn't have compromised such an important experiment like that. He looked over the four of them in turn, still wearing something of a stunned expression. Belle couldn't help but blush when the handsome cat so visibly scanned over her whole body. She had to turn away. Eventually, John gave them a small smile. Whether he spoke their language or not, that communication was universal. He approved. Meanwhile, Cassandra raised her hands and waved to get his attention, and began to speak very slowly.

"Hello. Can ... you ... understand ... us?"

John furrowed his brow and made a show of trying very hard to figure out what the tigress was saying. In the end he just slumped his shoulders, seemingly disappointed.

"Hmm. As expected, he does not speak our language, though he does seem to be familiar with the concept of language, at least," Cassandra noted.

"Then why doesn't he say anything?" Val asked.

Andi chimed in. "Maybe he's shy?"

"Shy? Why would he be shy?" came Belle's murmur.

"Well. To a species of feminine males, we might be ... intimidating." Cassandra leaned in a little closer. "Though it seems his body is reacting to us."

They all caught it more or less at the same time. That wild cat had a musk to him, and an altogether pleasant one at that. It hit them like a humid wave, washing over their senses one by one. Silence fell as a daze claimed their minds, at least temporarily. Each one of them in turn did her best to pretend it had no effect on them, but none of them bothered to act like they hadn't noticed. Of course they had. Even with an absence of sexual stimulation, the specimen exhibited a natural outpouring of pheromones as if primed for breeding at all times. Their bodies responded in turn, putting out similar doses of enticing scents, growing warm, damp. Belle found herself rubbing her thighs together, and Andi went ahead and adjusted her bra when she found her breasts feeling far too tender and swollen. Val was faring even worse, with the camo-pattern bra beneath her uniform showing dark marks as she began lactating out of sheer desire. The first stages of going into heat were well known to the four of them by then. Only the tigress didn't visibly react. Cassandra's tone remained as steady as ever. Maybe in her older age, she didn't have the same reaction, or maybe she was simply exhibiting a shocking amount of composure and professionalism.

"Yes. If our theories are correct, then John here is part of a civilization that is experiencing the exact opposite problem as our homeworld. And at a much faster rate. The anatomical adaptations are obvious at a glance. But just how far do they go? We'll need to test his capabilities before we commit to this project, of course."

She stopped and took a glance around at her coworkers, examining each of their strained expressions in turn. Andi had her lips pursed tightly, Val was clenching her teeth. As for Belle, she was simply trembling. She wasn't going to last much longer with that potent musk simmering in her nose and wearing down her willpower. Cass cleared her throat and made a sweeping gesture.

"Before that, I think we can all use a break. Andi and I can meet back here in 15 minutes. The rest of you, take a breather, however long you need. We'll call you on the intercom if we need you."

The tension left the room as if the four of them had been deflated slightly. They didn't say anything as they slowly slumped away, one by one, leaving John patiently waiting for their return. He didn't make any attempt to escape nor to follow them. It seemed he understood the process, for one reason or another. Val slipped outside and lit a cigarette while she gazed over the alien landscape. The breeze seemed to pierce right through her clothing and touch her warmest parts, making her acutely aware of just how wet she was. She pressed her thighs together as if to simply force herself to be calm through sheer will. Andi wasn't doing much better. She fanned herself while she sat sipping something cold in the breakroom with Cassandra. A sheen of sweat glistened upon her cleavage while her cheeks blazed so hotly she swore it must have been visible right through her fur. She glanced over at Cass to see how the older tigress was handling herself. As calm as the lead researcher might have been, Andi couldn't help but notice a little breach of protocol. Cass of all people was drinking on the job, even if it was just a single beer from their well-stocked canteen. And she downed it rather hastily, at that.

Nobody saw where Belle vanished off to. She was out of there like a flash. The thumping, pulsing need she felt was so potent there were juices running down the inside of her thighs. She returned to her personal bunk and flopped out with a mewl. Her legs were trembling so much she could barely get her pants down. There was really no question about what she had to do. Her panties were soaked right through with the pheromone-rich mess flowing from her. Just a few breaths of his musk and she couldn't come down from that lust-high. Her pussy was puffy, swollen, terribly tender. She could barely even touch herself. If only she'd thought to bring along a toy of some sort - but the fear of it being discovered kept her from doing that. Her own fingers were going to have to do. She sucked on them briefly and then went ahead and plunged them right inside her sopping cunt. There was no time to tease, no time to treat her gently. She had an aching, burning need, and she wasn't going to be functional until she took care of it. Yet even as she stuffed herself with her digits right down to the last knuckle, she knew well it was going to be a temporary fix, at best.

"Fuck ... " she swore to herself. That alone was unusual enough for her.

Soon she couldn't even mouth words beyond that. Her lips curled into an expression of feline desperation, with her fangs flashing, her tongue extended. She fingerfucked herself until she yowled out, without a care for who might hear her. Even those were hard to keep up. Soon she dropped into shaky whimpering, into weak little mewls and meows as she pumped her fingers back and forth. At first just two of them, and then a third, with her thumb putting on some good work on her clit. As if she needed any more pleasure. Every stroke brought forth a lewd splurch from her flooded depths, sent a torrent of juices splashing up over her whole hand. She marked her bunk in the scent of her lust, but she didn't care. Nothing could stop her. She arched her back and raised her hips up high as if she was actually being fucked. A clenching, contracting, squirting orgasm erupted out of her with a splurt of femcum splashing up in an arc only to come splashing down as a steaming hot mess. Even then, she didn't stop, absolutely pounding herself as roughly as she could, until her arm was too sore and numb to continue. Even then, she kept her fingers right where they were and just thrust her hips up into them, rapidly pumping down with vise-like squeezes the entire time. She drenched herself in the results of her needy outpouring, and it still wasn't enough. No matter how much she masturbated, she knew exactly what would put out the fire inside her. A fertile young cat like her needed to be bred if she was ever going to return to her duties with a clear mind.

Andi hardly felt any cooler even after an extended break and a glass of ice water. By the time she returned to the lab, she simply had to unclasp her bra entirely just to get some airflow. That meant just barely concealing her nips beneath that lab coat of hers, but she told herself it was strictly for professional purposes. Though John certainly seemed to notice. He glanced over as soon as that extra cleavage was on display, and his loincloth showed a visible twitch in response. So that answered the question of attraction. His eyes remained fixated on the lioness until she simply stuck her tongue out at him and turned away. Cassandra followed in just behind the other cat and started up some of the equipment without any comment. Though once everything was whirring and ready, she forward on a desk and let a smirk arch her dark lips.

"Ah, I see the subject is taking to you, Andi. That's good. We'll need him aroused for the tests."

"Heheh ... yeah," the lioness murmured, breaking her gaze from John. "Just what I was thinking."

"First, we'll need to do a routine physical to ensure he is not experiencing any severe health issues," Cass went on.

Andi nodded. "Right. The normal stuff. Of course."

She gave her own cheeks a little rub and shook her head just to break out of the daze she was in, and then it was back to business. With her tits out. She wasn't technically topless, but the slightest breeze of movement and she ended up flashing John repeatedly. He remained fixated on her, with only the occasional glance to the tigress while Cass set him up with various electrodes. She took his temperature, listened to his heart and stomach, and recorded his vitals. Aside from a slightly elevated heart rate, everything seemed ordinary and in line with what she might look for in her own species. Of course, John was an alien, but he seemed to display very similar traits to her kind. Nothing stood out as unhealthy. He was a most cooperative patient all the while, though he did occasionally lick his lips while he took turns staring at one of them and then the other. His cock filled out just a little more each moment, just standing in their presence. To say nothing of just how warm between the thighs the researchers were. The only reason Andi didn't catch the wafting cloud of Cass' pheromones was that John's proved even stronger. Being so close to him for so long was nearly unbearable in how arousing it was. The only thing that kept Andi from pouncing him right then and there was reminding herself how important the work truly was.

"I think we're good to proceed. Let's strap him in, so to speak."

Cass couldn't help herself a little grin as she gave the direction. Andi mirrored it briefly before moving to obtain what they needed. A large milking device might have seemed like an excessive piece of equipment to take on a discrete mission such as theirs, but it was exactly what they needed. It consisted of a long tube that connected to several smaller ones, and a central unit that collected the results as well as gave information on its properties. John stood fairly still and only squirmed a little as they rumbled in his ears and approached him with it. As strange as it must have seemed to such a simple species as his, he seemed to intuitively understand what was going on, or it seemed that way at least. Andi rubbed his shoulders while Cass calmly removed his loincloth, letting that massive dick truly flop out. It reached down to his knees just at rest, and semi-firm as it was, it was easy to slide into the tight grip of the device. It latched on to the exact shape of his cock, slowly kneading it. As warm and wet as a pussy, it simulated the experience nicely. All he had to do was stand there while Andi supported him from behind and Cass hit a switch that started the milking process. It was the first time they actually heard his voice.

"Nnngh ..."

Andi squeezed his shoulders soothingly. "Shh shh. Just let it do its work. We need to see if you're truly the stud you seem to be."

"I'm not sure if 'stud' is the proper scientific term exactly, but I think it captures the right intent. After all, a big dick doesn't make a stud, alone ..."

Andi chuckled at that. The device made a steady whirring that blended in with John's occasional moans. They sounded so soft, so feminine, so unbefitting of a breeder like him. His shaft swelled up to its full size, pulsing in the wet grasp of that simulated vagina while it worked back and forth. Schlick schlick schlick went those artificial juices as they lubed up his every inch, engulfing him right down to his bloated nuts. Cassandra looked up from the milking device's central unit just to watch his balls bounce a little. Then it was right back down to the displays and readouts. He was already giving them such a generous amount of precum. It flowed up through the tubes and into a basin, audibly dripping to the bottom. John started slowly thrusting his hips back and forth, which meant bumping his backside against Andi's thighs. She was so much taller than him, wider too. It would have been easy to just wrap him up in a great warm hug and take him down to the floor and ... but she remained as steady as she could and focused on applying one of her other talents, kneading deep into John's shoulders while he writhed in her grasp. If she hadn't been a scientist, she might have been a masseuse, with fingers like those.

A creaking sound came from the milker as it accelerated to top speed, pumping, squeezing, working the specimen's shaft until he was twitching all over, barely able to stand on his own paws. Andi made sure to keep him from collapsing while that delicious device did its work. A sudden clench ran up his spine, making him shake wildly. Despite the fanfare, John's orgasm didn't get anything more than a soft whimper out of him, as if he could hardly even believe how good it felt. It came suddenly, with a sharp jab of his hips forth and a hot spurt of cum that rushed through the tubes to flood that basin full. A few good shots was all it took to overflow the device and leave the tubes all packed with extra spunk. Cassandra watched his balls bounced and clenching while he milked out that extra-potent dose of pure seed. All the readings were green. That was the real deal, a virile load of breeder cream that could have singlehandedly impregnated a whole city block back home. Elation briefly came over the tigress' features, a great grin flashing on her face before she composed herself and became professional all over again. They had really done it. There was still work to be done, of course - milking an alien species for every future breeding was hardly the complete solution. But, with enough analysis, something could be synthesized, and ... oh dear. What was John doing? No sooner had he finished cumming, and he was already bucking and grinding, thrusting into the now-dormant device with a deep grunt and a shaky little gasp.

"Woah there! So eager!" Andi chuckled. "I can barely even hold him. Should I ... try to stop him?"

"Not at all. We need data on his refractory period," Cassandra noted. "It seems ... zero may be a reasonable conclusion. Resetting the device."

After Cassandra swapped out that overflowing basin with an empty one, the simple touch of a button was enough to get the process working all over again. This time, John was even less restrained. Maybe he'd been nervous before. This time, he had two hands around that milking tube and was deeply fucking it. A mix of mewls and light growls escaped him. Andi didn't have to calm him down anymore. She moved around to the front, breasts bouncing with her every step. John had his eyes half-closed at first, but at that sight, he opened wide again and just fixated on that cleavage she had on display. He accelerated his pace at the sight of that. Andi couldn't help but beam with pride to know he was getting off to her. There was something flattering about an alien species finding her attractive. Or maybe she was just exceedingly horny. Watching that femmy cat work proved just how much of a stud he had hidden away in his girly frame. It wasn't long before he fucked that device full of spunk yet again, never breaking eye contact with the lioness' breasts the entire time. Yet for as much as he might have wanted her, he didn't take a single step to take control or make the first move. For a seemingly primitive specimen, he was very polite. Or just shy, despite the performance he was putting in for his benevolent captors.

After that, he was finally panting. He slumped a little, but still tried to thrust into the tube a few times while the last of his jizz flowed through it. Andi reached for him and gave him an approving pat on the head before freeing him from that milker. A splat of cum to the floor made her shiver, especially when the musk of it really hit her. She found herself swishing her paintbrush tail and curling her toes into the floor. Turning to Cassandra, she found even the tigress looked a little flustered. The striped cat kneaded her own breast seemingly absentmindedly while she confirmed the readings, murmuring to herself. Only when Andi cleared her throat did she perk up and pay attention, as if awoken from a day-nap.

"Ah! Well. I am very pleased to say that the results are beyond anything we could have possibly hoped for. His sperm count, his volume ... well, I'm sure you get the idea. He's more than doubled our projected goals in just two releases."

Andi turned back to John, who by then had slumped down on his butt to catch his breath. He was still hard as ever, though the urgent thumping had subsided. It was more of an idle horny - ready for more but not as needy. That was very much the opposite of Andi's situation. She could outright feel the juicy results of her ensuing heat running down her thick thighs. Her breath came shaky whenever she inhaled. Turning to Cass, she huffed out without a word, and the tigress simply nodded.

"Yes, I think I agree. When doing this sort of delicate work, we want to make sure to take plenty of breaks. For our sake and for the subject's. It looks like he could use a rest, wouldn't you say?"

"I know I do ... and a few other things. But maybe rest will suffice, for now," Andi muttered, all but groaning out her words.

By then John's musk was nearly choking to inhale, in the best of ways. It was thick and potent and it invoked such a primal reaction in them that they simply had to be far away from him for a while. Not that it did much to improve their mood. His scent clung to them as if marking their fur. They didn't speak much as they huddled in the break room once more, leaving John to recharge and recover. Andi drank her cold water, and Cassandra went right ahead and had a second beer. A big cat like her wasn't going to be affected by a little booze, though Andi couldn't help but notice just how unusual it was for her. She wasn't concerned, of course. If anything, it was a comfort. The breaking of protocol meant that beneath the stoic demeanour, her boss felt every bit as affected by the potency of their subject. Andi had to keep her mind on the scientific implications of their findings at all times, lest her imagination flood with images of her and John's body pressed close together, naked, finally working out those mutual urges they'd been feeling since the very start. Not everyone in the base had the same level of discipline. In the silence of the lab, John didn't seem to notice the stealthy approach of the pantheress.

Instinct was a powerful enough force to make even the strictest, most disciplined of soldiers forget her duty for the sake of indulging her most basic needs. Val felt as if she wouldn't survive if she didn't give herself over to her urges. John made a faintly surprised sound as she took him down from behind as if pouncing on some ancient prey. She was a beast of sensations, of inner urges that beat out her higher thoughts for as long as that fire burned inside her. She'd left her garments in a trail through the lab. That alien cat found himself pinned beneath the silky muscle of the sleek black cat while she rumbled her desires into his face. His response was to swiftly erect for her. It didn't matter how much they drained him. He was still ready to go, ready to breed, to give her everything she wanted from him and more. But first, just to make sure she'd made her point completely clear, Val whipped her rump around and lifted her tail high so she could make a seat out of the specimen's face. Even at the height of her instinctual lust, she still felt the need to assert herself, and to get John every bit as drunk on her scent as she was on his.

"Gooood boy ..." she rumbled to him, whether or not he understood.

By the vibrations he returned, perhaps he knew she was praising him. Or maybe he simply liked this turn of events. Val hardly showed him any mercy. She planted her soaked pussy right atop his muzzle and shoved it against his lips with the utmost of insistence. If he'd hesitated in the slightest she probably would have given him a snarl of encouragement, but it didn't prove necessary. John swiftly took to slurping her cunt in big sloppy strokes of his tongue That meant getting mouthful after mouthful of her juices, of her intense, overwhelming pantheress flavour while she snugly sat atop him, grinding back and forth for maximum friction. With that mess pouring from her with each lick, Val could hardly remember the last time she was so damn wet. The feeling surging through her veins was beyond horny and into aching, driving fury. Rather than moan her approval at his generosity, she instead gave him some fearsome growls that resonated right through the lab and no doubt disturbed some of the sensitive equipment. She didn't care, nor was she worried if anyone heard her. Surely they weren't far behind in giving themselves over to their bodies.

John ended up drenched in those velvety panther fluids, his hair all flattened down to his head by the layers upon layers of liquid lust that cascaded down from her shining folds. Every spatter upon her fur made her all the sleeker. She clenched and humped and rubbed her clit right against the alien cat's nose, but eventually she had to let him up lest she drown him before she got to the good stuff. John hardly complained. He gasped at first when she raised her rump from atop his face, but that was the extent of it. The look on his face didn't need any sort of translator to decrypt. That was a horny look if ever Val saw one. The hard cock standing tall right in front of her was another sign. She leaned in close and gave the tip a few rough licks just to see if she could make John moan. A little whimper escaped him as he trembled beneath her, kicking his legs about, thrusting his hips up towards her face. She smooched his inelegantly jabbing dick and turned herself to face him, laying out over his whole firm. Given just how much larger than him she was, he all but disappeared beneath her, just a pair of paws sticking out between her thighs while she rubbed her soft fur against his own. His head ended up trapped in her cleavage, all smooshed in those tremendous tits, taking in the pheromones accumulated there. He was just as eager at sniffing as he was at licking.

She left him there a while, with a palm pressed to the back of his sodden head, sliding up and down the pole of his cock. Her pussy lips made such sweet schlicks as she went gliding along his every inch. She wasn't sure why she was teasing herself for so long, but everything felt so good she permitted herself a minute or two of simply grinding against him until the ache within her grew unbearable. It wasn't even the pleasant kind of horny anymore. She burned with pure animal lust and she needed to work it out on his girly-stud body before her mind broke. With a sudden arch of her back, she rose from his face and seized him by the wrists. He throbbed against her ass while she planted her knees and got herself into position. Even at the height of her heat, Val still very much wanted to be in total control. John wore a great big dumb grin on his face as if to assure her he wanted her just as much as she needed him. Despite her bulk, she could work her hips smoothly and slowly to settle that heated cunt down against his tip. From there it was just a matter of going on the slow, hot slide down every inch she could possibly cram into her clenching cunt. The first squeeze was tight enough to make him yelp a little. She tried to tone down the death-grip after that.

"Ahhhh ... know you can't understand me, but you're doing me a great service here, John. It's been ten goddamn years since I got fucked hard enough to feel it."

Maybe he didn't know what those words meant, but he understood the sharpness of her tone. He gazed back at her with a look of utter adoration, as if to display hearts in his shiny eyes. She worked down until her pussy lips almost kissed his balls, but that was where she had to stop, lest she injure herself. Maybe in time, with enough training. She made the most of what she could fit, plunging up and down that pulsing spire while she kneaded him with the constant contractions of her inner walls. Occasional, she let a tremble slip into her dominant posture. It coincided with her curling back her dark lips and flashing her teeth at him. He made no such gesture in return. The most he gave her was a timid mew while she started bouncing that fine ass on his dick. His copious precum output mixed with her excess juices to make for a truly messy plunge every time she came down on him. A thud of her body against his rattled his girly frame each time, but she didn't slow down for anything. She could tell he was tough, maybe even made for exactly this kind of thing. And the constant clenching of his bloated balls meant they were playing for keeps. She could feel it in the air, in the musk that flooded her senses, in the tingling sensation deep inside her as his potent pre flowed towards her womb, drop by drop, gush by gush. She was going to let that girly alien get her pregnant, at last, after so many years of debilitating heats.

"Rrrrrgh ... hold on tight, John. I can't stop myself ..."

There wasn't a trace of anything apologetic in her tone. Those were simply the facts. She outright drooled on him while she rammed his rod straight between her tender lips. A mighty squeeze halted her progress now and then while she shivered in delight. Nigh-orgasmic pleasure jolted through her every nerve every single time she bucked down on his dick, but that wasn't enough to shake her from her path, from her goal. Her entire existence came down to that moment, or at least that was how she felt. Perspiration flowed freely from the both of them, but especially from her, to rain down upon his pinned form as musky precipitation. Her own heated scent was nearly as strong as his at the height of their wild mating. The cocktail of pheromones flooded through the room and right down the hall while she rumbled her way to climax like the dark cloud she was. The river of hot panther juices rolling down her thighs served to highlight just how hard she was working, with those muscles bulging with the effort of slamming herself down on the femmy cat's supple body. He could only hang on tight and squeeze her ass while she pounded him into her with a steady slap of their bodies meeting and a thud of her mighty frame crashing down on his. And then there came her roar.

If she'd intended anything resembling secrecy, then she threw it all out at that point. There was nothing keeping the black jaguaress from announcing to the whole lab exactly what she was doing. Nobody came rushing in to stop her. She got exactly what she wanted moments later when the clenching grip of her orgasm milked John right over the edge. He curled his toes where they were visible beneath her and gave a few manic thrusts upwards that seemed like they simply happened automatically. She finally took him all the way to the nuts just in time to feel them pumping up tight as he got ready to fill her up. The stretch didn't bother her. All she felt in those perfect moments was sheer, scream-worthy pleasure unlike any she'd ever experienced. It was enough to make her screech just a little when that thunderous roar died down. She gnashed her teeth and outright spat on him for the sheer mess she was making in the process of cumming her brains out for that silly little stud of a specimen. Her flexing, undulating walls finally were too much for him to take, and she milked out a massive cumshot that felt like a soothing wave over the fire that burned inside her, despite the rich heat of that virile spunk that shot straight up inside her womb from the sheer velocity. He fired into her like a cannon and he didn't stop, especially not with her cunt draining him with such feral hunger. A squirting splash of sex splattered over their bellies and thighs alike, rolling down John's hips until the floor was a puddle. The milking device had been pleasant enough, but it couldn't compare to the warmth and tightness of a silky panther cunt in heat.

Val found herself so stuffed with cum that she ended up with a bit of a belly where her taut abs had been. She squeezed on him until he gave a less happy whimper that she recognized as slight discomfort. Only then did she finally settle down with a slump of her shoulders and a sigh. The world came flooding back. She found herself aware of her surroundings once more. The lab was oddly quiet, but for the sound of her own rasping breath. She slowly pulled from John's cock with a few muted snarls, nearly picking him right up off the ground in the process. With a glance from side to side, she clutched her cum-bloated belly and went sloshing off to her bunk to recover from that breeding. There was nothing more to say. She was lost in a haze of satisfaction, as if everything in her life had suddenly been made alright by the presence of hot cum inside her womb. Of course, treading down the hall naked and glistening with sweat and other fluids had a way of wafting that mixed musk all around the base. The ambient heat level seemed to rise wherever she walked, until she finally just collapsed with a grunt into her bed, leaking the excess juices onto her sheets. A fuck like that wore out even that powerful pantheress. She was going to need a little rest, and that meant stewing in the bliss of being bred, at long last. Science stuff didn't make a ton of sense to her, but she felt like the experiment had been a success, as far as she was concerned.

"Now what happened here?" came Andi's teasing voice as she stepped back into the lab to find John sprawled out and splattered with juices that definitely weren't just her own.

"By the scent, I would say our security officer felt the need to contribute to our experiment. Surprising, truly. I would have thought our pilot the first to break. Or you." Cassandra pushed her glasses up and simply smirked. "You needn't worry about it compromising anything. A little hands-on work will help us determine the true extent of his abilities. And his fertility."

The lioness looked over to her boss and couldn't help but let a little visible relief wash over her as she heard that. Such a casual approach meant she could relax her shoulders a little. The experiment was far from ruined, after all. And knowing that giving in to those primal urges wasn't just permitted, but expected was oddly enough what allowed her to focus a little better on the task at hand. Though not without the occasional squeeze to her tender breasts, or a slick rub of her soaked thighs against one another. When she examined the tigress closely, she was at first stunned by just how well Cass managed to keep herself together, but now and then she spotted the signs. A twitch of her tail, or the corner of her mouth, along with a shift of her eyes. Even that stripey older cat was thinking the same thing as her. It was only a matter of time before they both got what they needed, but first, it was wise to do as much work as they possibly could. Returning to the sex-soaked feline, they hooked him up with electrodes once more and took some measurements of his well-worked balls to see if they'd grown any less swollen after three massive releases. Of course they hadn't.

Meanwhile, Belle felt like she was dying. Masturbating hadn't fixed her problem. If anything, those tenderly touching fingers had only served to press all her buttons and make her even more needy than before. She ached enough she could have screamed. Her pussy was swollen to the point she hardly even dared touch it. Her heated breath steaming through the air just made things worse. And just where was that scent coming from? She'd always had something of an attraction to their security expert throughout the whole trip, especially when she got all sweaty, and breathing that mixed with the undeniably potent aroma of femmy male musk was enough to drive her absolutely wild. She felt like a prisoner in her own body, unable to even rise from her bunk at first until she dug in her claws and really forced herself to her feet. Her legs might have been shaky and the air rushing over her molten pussy was nearly painful as she strode out of her chambers, but she found herself motivated by her new mission. And she was ready to beg to get what she needed, if possible.

She thought nothing of showing up naked to her coworkers. The two researchers turned her way and each gave her their own brand of knowing smile. A broad grin from Andi, along with an encouraging nod, and a soft, fond gaze from the tigress. They both knew why she was there. Though her desperation meant she really couldn't afford any sort of delay. Not when she had a throbbing, pumping, ravenous heat burning away between her thighs. She gave them a wild-eyed pleading look as she clutched her hands together before them.

"Cass. Andi. I have to ... I really really want to ... you have to let me ... I know this is all so important but if I don't have him now I don't know what's ..."

She trailed off, unable to even fathom how it would have felt to deny her body what it so intently called for. Her features twisted into something like elation, if a little unhinged, when she saw the tigress nod to her.

"Of course, Belle. If my assumptions about Val's methods are correct, then so far we have simply seen him being milked." Cass nibbled on the tip of her finger. Andi couldn't help but notice the slightly nervous gesture as the tigress continued. "We have yet to see him fuck. Nor do we know just how long he can keep going. It could be a vital data-gathering process, if you think you can endure it."

As for whether John was up for it, they hardly had to ask him. He had turned over by then, propping himself up on one elbow to lay out all the goods on display. His cock was hard again. He didn't seem to mind the throbs it made, far from overstimulated just yet. Now and then he took a sniff of the air, his eyes firmly trained upon that swollen snow leopard pussy. Belle was audibly dripping by then, and she only got wetter when she noticed the intensity of his gaze. Her bosses both gave her a nod of encouragement. All she had to do was take the plunge. After all that anticipation, she found herself hesitating ever so slightly. For three seconds or so. That was when the arch made itself known with a sudden throb that left her pussy clenching up so tight she almost buckled from the sensation. No more waiting. Even if she had to stagger, she had to feel the alien cat's touch immediately, lest she lose her mind or perish from the strain of enduring such an overpowering lust.

"H-hey ... don't go easy on me just because I'm smaller than the others ..." she murmured, seeming to forget he couldn't understand. "I really want everything you've got."

She knelt down in front of him and he rose to his knees. They were face to face for a few seconds before he leaned in for a smooch, a playful little peck on her lips. She returned it and he countered with a much firmer kiss that had them locked together and exchanging tongues moments later. They pushed into one another, back and forth, seesawing for dominance until Belle finally just gave in to his charms. She fell back and let him catch her in a firm embrace. From there it was a matter of pouncing atop her with an eager mewl. They were about as curvy as one another, but she was still taller. That didn't stop him from overtaking her in nibbles, in gropes, and in messy, thrusting humps that slapped his cock against her belly and breasts alike. She was content to let him titfuck her a little just so she could get a good taste of that impressive tool. Her licks were modest at first, but swiftly fell to sloppy, drooly slurping as she slathered his tip up in spit while he rubbed into the crevice of her breasts. She soon found herself smeared with his massive musk, soaking it up like a sponge, her skin and spotty fur nicely marked by the potent scent that made her pussy quiver with every single breath she took. A throaty mewl was her way of telling him she couldn't wait any longer.

When he finally entered her, she could feel the shockwave of pleasure and relief right down in her bones. A sharp arch of her back made her look briefly possessed by pleasure as John shoved smoothly, if roughly, between her thighs. He wasn't the most elegant of a lovemaker. Belle really didn't care. A crude thump thump thump was everything she wanted in the world while she clenched up tight around him and tried not to lose control of herself. She madly clawed at his back, thankfully not without doing any real damage while he sunk inch after inch inside of that noisy snow leopardess. Each thrust pushed a little deeper, and even if he didn't quite get in all the way, he still had plenty to hammer her with. His humping motions were simple, wild, maybe even uncoordinated, driving Belle down onto the floor over and over again. She had no need for a bed. The room faded from view as she got fucked senseless right there on the floor of the lab, under observation of her coworkers. The splatter of juices spread out in a puddle around them as John pounded the eager cat with all his feminine strength. Maybe it was for the best that he was on the leaner side when he had such an imposing tool to wield. Belle was already making some of those broken mraaaawls that spoke of her diminishing mental state with every single driving thrust deep into the humid depths of her heat-soaked pussy. And John never relented on her, keeping his pace unflagging if not exactly steady even while she broke into the screechy part of the feline vocal range.

Andi did her best to keep coherent notes while she was absolutely aching at the sight of that wild breeding going on before her. The slaps were hardly even audible anymore for the sheer schlurping of Belly's impossibly soaked cunt. The lioness half wondered if she should have been conducting experiments on herself along with John. Being in his presence had such an effect on her that she'd soaked her panties to the point of translucent. Each stroke of the alien cat's glistening cock into the snow leopardess brought with it a squishing squirt of juices squeezed out by the sheer pressure. Belle was already flooded, already overflowing with her own lust long before John even finished in her. She tried to get her legs up to wrap around him, but every thrust just flattened her out again. There wasn't much she could do but be a cushion beneath the horny alien while he hammered into her with a drooly grin on his face. They didn't need to worry about the ethics of it all when he wore an expression like that of someone whose every dream was coming true. Horny, busty ladies to breed, again and again, was enough to satisfy his relatively primitive mind, for as long as they needed to study him.

A few of those measuring devices started beeping with errors as the heat level rose in the room. A cloud of warmth rose from Belle's body as she clamped down on John's dick right to her first of many peaks. Cass swiftly took to typing on the console in front of her, but Andi couldn't take her eyes off of Belle while that spotty cat twisted and shook with a gushing climax that had her mewling out a disproportionately gentle sound. She couldn't manage anything better. With her eyes shut tight and her face all scrunched in a silent snarl, she bucked her hips up into the alien cat's cock and took it as deep as she possibly could without hurting herself while she rocketed right through a peak that left her soaking his dick from tip to balls in fragrant lady juices. He slammed down and gave her a grunt of his own while his eyes partly rolled back from the sheer delight that came with emptying his nuts in a hot cat cunt. A constant, heavy roll of his hips all throughout their mutual orgasm ensured he fucked his cum right up inside the snep's needy womb. He flooded her with that potent spunk and drew back as if to pull out, but that was nothing more than him angling himself to give another lunge into her squelching depths to squeeze out some of his excess seed while he went at her for another round. He didn't miss a beat, nor did he offer her a moment's rest. She didn't need it.

"Rrrrrrrgh ...!"

It was a sound most unlike Belle's usual self. There was ferocity in that snarl. Though she didn't muster anything beyond that. She remained beneath him, not exactly pinned so much as she was just rendered helpless by rapturous pleasure while the alien cat fucked her fertile pussy just as hard as the first time. The sloshing of his seed inside her helped to douse the ache she felt, replacing it instead with a satisfied tingle, a direct reward from her mind for fulfilling that biological need. Bred, at last. She had no doubt she was already pregnant from one of John's massive cumshots, but the thought remained in her mind. How much more pregnant could she get? Maybe it worked like that when she was dealing with someone as potent as he was. All she knew was he made her body feel good, jiggling her tits up and down with his every eager hump. The sheer desire he radiated in every stroke made the whole experience heavenly. Even if her body was going a little numb from all the stimulation. There was only so much pleasure she could possibly process before she found herself going blank. From mewling, she fell to silence, to staring, hardly seeming to register where she was anymore. Meanwhile John just kept fucking her. He could hardly be too concerned with her state of mind when she was so very warm and tight around his enormous cock.

"Hmm, I think perhaps ..." Andi began, but before she could finish, she heard another orgasmic grunt from the alien as cum flowed thick through his mighty shaft and into the snow leopardess.

The sound of a jizz-stuffed cat getting another cumshot right in her flooded pussy rang out through the whole room. The SPLURCH was truly excessive, drowning out all other noise for a few seconds while John emptied his nuts in Belle until she was swollen and pregnant-looking with the overwhelming load. Not that she didn't cum too. Having those fat breeder nuts tapping against her thighs and ass, clenching, pumping, releasing, was enough to make her squirt again. Andi watched those streams shooting off in all directions, mixed with John's cream, painting down the whole surrounding area. She was mildly concerned about some of the equipment, but that thought was firmly at the back of her mind while she watched John ravage and pump and swell Bell right up into a spotty cum balloon. He didn't soften, nor did he seem ready to stop. She saw him rising up for another thrust and went ahead and cleared her throat loudly. John turned her way, but Belle hardly moved. She might have passed out briefly, or at least found herself too disoriented to respond, numb and dumb, fucked raw and bloated with a musky load that ensured she was going to bear the breeder cat's young. Stretched out in a pool of jizz, dazed and confused, was exactly where she stayed as all other eyes fixated on the lioness.

Andi couldn't help but feel the intensity of Cassandra's gaze upon her. It made her words come out just a little sheepish.

"Ah, I think perhaps our lab assistant needs a little break. And John himself hardly seems done, sooooo ..."

Cass gave a quiet chuckle. "Most practical thinking indeed."

Andi laughed as she dipped her head down. "I have to know."

"Of course. Your experience will serve you well here," Cass noted.

It was a very polite way to call her a slut. Andi was pretty sure it wasn't meant as an insult, and she certainly didn't take it as one either way. Instead, she abandoned her notes while she shed her lab coat at last. The sight of those absolute monster-tits on full display was enough to leave John's eyes boggled. He pulled out of Belle with a little splurch that made the snowcat gasp and left her to her well-creamed purring as he rose to greet the approaching lioness. Andi stopped only to take off her pants and undergarments - a process that took a lot of peeling just to unstick the fabric from her drenched sex. Her scent flowed through the air and right into John's nose when he took a few deep sniffs and stepped towards her, dick soaked with jizz. A dripping trail followed his every step until he rubbed that titan of a cock against her thigh. She enveloped him in a hug that lifted him right to the tips of his toes. He completely vanished in the valley of her cleavage, and soon found herself rumbling at the sensation of getting her sweaty, tender tits licked. Keeping him close, clutching him, squeezing him, she slowly sank down to her knees with the intention of getting on top of him. Somehow things just didn't go as planned, and it wasn't for any degree of force on John's part. Making a great big bed of herself just came naturally to her for whatever reason.

"God, his musk ..." Andi muttered through clenched teeth.

"Its properties require further study. The aphrodisiac effects are ... notable," Cass admitted.

The thickness of the scents in the air helpfully masked the tigress' own. Andi might well have been shocked to know how horny her boss really was. Though her focus was mainly on that soft, girly fuckbeast between her legs. She made sure to wrap him up nice and tight so she could maintain at least some semblance of her powerbottom image. John found himself tightly squeezed between two treetrunk thighs while he remained immersed in her cleavage. She ended up squishing them more firmly around his head in the process of hugging him close to her body. She squeezed him so tightly as if to absorb him, or simply to claim him. There was no suppressed that streak of greed that ran through her after seeing John go to town on Belle like that. She wanted to be his favourite, and she clutched him close to her exquisitely plush curves to encourage him to make that decision. Not that he was exactly a discerning lover. He pressed up over her sex and swiftly found his way inside of her. Even with a cock like that, penetration was smooth and easy thanks to the absolute oozing mess of thick lady lust clinging to every single fold of her swollen pussy. One good, hard thrust and she found herself clamping down on the biggest dick she'd ever had inside her.

"And his dick," was the best she had for scientific observation.

"It does seem very capable," Cass agreed. Andi was pretty sure she was teasing her by then. She couldn't even hear the stripey cat typing anymore.

The truth of it was, even Cass wasn't immune to her own urges. She let her typing fingers wander until she had them stuffed down her pants, as if they'd found their way there all on their own. A slow, casual masturbation session was her silent comment on the sight before her. Oh, how those tits jiggled. Andi's bosom bounced up and down while John started pounding her. He seemed to carry the momentum over from Belle, quickly firing up to the same pounding pace he'd left off with the last cat. Andi's bigger, softer body was even more receptive to it than the slightly broken snow leopardess. Belle was perfectly fine, but she needed a minute or several to properly realign her mind and recover from the very same slamfuck he was currently giving Andi. The lioness' ultra-plush body made for the perfect cushion for his eager humping, though the wobbles that ran through the big cat's curves were tremendous. Cass fingered herself just a little more rapidly as she watched Andi getting pounded, and listened to the lioness' proud rumbles and half-roars melt down to something more like a tabby cat. She mewled for that great big dick. It could satisfy even the endless well of lust that was Andi.

"Ah, he's just ... it's like he knows ... it's ..."

That was as far as Andi got. Even Cass found it hard to respond coherently.

"From initial measures, it seems he knows exactly how to fuck to ensure maximum receptiveness ... if you weren't already in heat from his scent, then you will be once he's inside you. Very ... impressive."

She grunted through clenched teeth as she buried three fingers deep into her folds. It was hardly enough to take care of her needs, but it helped extend her patience, at least. Andi squirmed beneath the femmy cat just enough to get his face against one of her tits. He automatically latched on and started sucking without even needing to be told what to do. Those hungry kneads and suckles were more than enough to get the milk flowing. It ran rich and warm into his mouth, but chugging right from the lion's teat didn't make him lose his pace. Some of that fresh kitty cream splashed down the side of Andi's bust while he slurped it down. She leaked from both at once, and he swapped from one to the other as quickly as he could to try to catch it all, but of course he couldn't possibly manage. It was a valiant effort, at least. Andi would have let him keep on drinking from her if she didn't feel those inner muscles clenching up with frightful force. It was enough to make her whole body curl up around him, squeezing tight, latching on, ready to milk him for everything he could possibly give. She dug her heels into his ass and she bear-hugged him right between her tits again while she launched herself over the edge into yowling orgasm with that potent breeding tool pointed right at her womb.

The gush that followed was like a tug-of-war just to see who could cum harder. He shot his jizz into her and she squirted it right back out with the sheer force of her climax. Her face was a snarl but her voice was a shaky mess as she got herself impregnated by that girly alien cat. All those years of waiting, and fucking, and it was finally going to happen. It was like she finally reached her goal. And she didn't want to stop. She made sure he kept on cumming until he was absolutely dry, thighs locked around him like a padlock, breasts serving for cushions to muffle his moans while she squeezed on his dick and soaked up a full gallon or two of fresh cat spunk. Only when he gave a little whimper did she relent. She was crushing him, just a little, with those thighs of hers. She sighed and relaxed at last, sinking down and letting him rest in her cleavage for as long as it took to catch his breath. Maybe he was finally done. She swore she felt him soften briefly as he started pulling back from the flooded cavern that was her cunt. But then he twitched again when he saw something he liked.

Andi wasn't sure if she was really seeing what she thought she saw when she glanced over. Cassandra, the big boss cat, was fully naked as she strode over towards the subject. Her uniform was neatly folded at her workstation, and her sex was a glistening mess of juices. She got down on all fours as she reached her destination, tail up, back arched, and a flirty look directed right at that horny test subject. Even she couldn't resist some hands-on science. John was panting as he jumped up, slouching with fatigue, but he didn't let that stop him. Such an opportunity came once in a lifetime and he wasn't going to squander it. Andi watched with blurred vision as the tired breeder mounted the shapely milf of a tigress from behind. He knew just what to do. He looked so silly kneeling there behind those broad, striped haunches, so small, so cute. Yet he could make even someone like Cassandra yowl. She hardly even got her snarls in before her voice grew soft and cattish, just like all the others that took his cock.

"Is this still ... for science?" Andi managed to mutter out as she stewed there in musk and satisfaction.

"Oh this? Rrrrrrrmmmmm ... " Cass began, cut off by her own sounds of pleasure. She came to a simple conclusion. "No. This is for me. I refuse to continue this mission until I get as pregnant as goddamn possible."

The words came as such a shock to Andi. She was pretty sure she'd never heard the tigress speak so bluntly. It was even more of a sight to see Cass show some aggression, bucking her hips and flashing her teeth at the girly stud behind her.

"Fuck me! Breed me! Don't you dare tire out before you knock me up with your precious seed, subject ..." came her fierce command.

John understood it just fine. He didn't flinch, and instead rose up tall to lean over her back for the perfect pleasure angle. Since he wasn't tall enough to nibble her neck, he settled instead on her spine, giving her some love bites while he jerked his hips back and forth to make that milfy body wobble. Cass kept her hands planted and her head raised for as long as she could, but even she had her limits. Pleasure like that changed people. And not just temporarily. So she allowed herself to sink down beneath him, to look conquered after a mere minute or two of getting her pussy stuffed. This time, John didn't bottom out early. He went in all the way, balls-deep in tigress so he could slap her with his sack with every harsh stroke. Now and then Andi spotted his energy wavering, saw him slump down, only to recover. Maybe it was the threat of what might happen if he stopped, but more likely the pussy was just that good. He could stand a little soreness in the morning if it meant getting to fuck and breed that lovely older lady nice and deep. Her belly outright bulged with the size of the insertion, but her flexible sex accomodated his every stroke, his every deep-rutting pound. She bucked back into him with some thumps of her hips as if to make him fuck her even harder. Even down on her face and drooling, she still had that seasoned feistiness. She refused to let him give her a sub-par fucking just because he was a little drained.

Rather than a rapid thumping, John instead turned to long, lunging thrusts, tip to nuts. Each one was harder than the last. He bred her like he was trying to break down a door, wielding that battering ram with brutal force. Cass just squeezed on him and took it, no matter how rough he got. Maybe he sensed just how much he could endure. Such tests could come later, when they were calmer. For now, the tigress was occupied clawing at the floor so fiercely she carved into the tiles there, scarring the test chamber with the signs of her ferocious lust. She raised her head briefly, only to droop down again as the effort failed. There was no rising up or looking more dignified. Her arms didn't work anymore. She felt her cheek sliding through some of the splashed juices of previous mating that was smeared across the floor. None of it bothered her. For a little while, she didn't have to worry about being the boss. She could just be a horny tigress who was about to get made into a mother to match her matriarchal curves. And all she could do was yowl about it, far too lost to lust to even roar her way to heaven when she felt the cum flowing.

Poor John was trembling by the time he finished in her. He was truly spent, desperately clinging to her hips while he bred her full. That wild kneading on his dick drained him of every last drop he had left. Which was plenty enough to fill out and weight down Cassandra's belly with that sloshing preview of her long-awaited pregnancy to come. She arched and bucked and squeezed tight until she finally slumped. Sprawling out on her front as low as she could get, she splayed out her four limbs and made a blanket of herself while she drooled on the floor in a way most unbecoming of a widely-respected scientist. It didn't matter. She got what she needed, and in the process she had learned a great deal about their subject. Though there were plenty of notes she was going to need to take. After a little nap, perhaps. John seemed to think much the same as he flopped back and just collapsed there behind her. Their bodies were far too warm for cuddling, so they just laid there and steamed in the post-orgasmic heat. Already, Cass could detect some sort of inner tingles working through her womb and ovaries, like electricity inside her. She didn't need any fancy degrees to know that was the feeling of a pregnancy taking.

Maybe it was the environment, or maybe it was just the potency of their test subject himself, but the research team's gravid state advanced far more rapidly in the following days than any of them expected. They were round and shapely within days, then swollen right out to a debilitating size by the end of the week. Research was admittedly slow in such a state, especially when it involved plenty of slurping, sucking, and riding that studcock whenever their urges won out. Cass, Andi, Belle, and Val alike were all massively pregnant thanks to John's seed. Their tits sloshed with milk and their bellies were stretched taut to the point of popping their navels. They took turns making recordings and sucking on John's cock, or sniffing his nuts. The lucky specimen got treated like a king all throughout the testing process. By the end of the second week, it was hard to say if there was still much to study, or if the cats were simply indulging themselves with their happy captive. Heavy with a whole litter of his offspring, some of them found themselves considering other options - like creating a whole new colony right there on that planet. John was just one of those wide-hipped studs. There was a whole society of them, each of them surely as eager to fuck as he was. Nobody could have judged them for taking first dibs.
