"Bring in the subject!" Responding to the words said over the intercom, the scientist overseeing their latest project pressed a button that controlled the doors. He was safe behind an incredibly strong wall of glass. It was a good thing for him. On the other side of the glass was a tiger. He wasn't like any tiger you would find at a zoo. The facility was in need of test subjects and the wild feline was easy to come by, being the runt of his litter. It had been a long time since then and the lab's many experiments that changed the beast greatly.

The most immediate thing about the tiger was his look. His orange pelt had turned a shade of sky blue and the stripes were an even darker shade. The white along the underside was the only thing that remained the same as before. That aside, the creature was also huge. Tigers were already naturally huge but thanks to the facility he was prowling about at a staggering 6 foot 5 inches.

Catching the feline's attention were the pheromones of a tigress in heat. They led the tiger to the breeding mount that was set up for him. After a few sniffs there was a stirring between his hindlegs. It was made obvious when his sheath was being spread by his emerging cock. Like the rest of him, the feline's cock was much bigger than what it was supposed to be. The lengthy and thick tiger length reached its full mast and began throbbing. Sure the mount smelled like a tigress, but it certainly didn't look or feel like one.

All the same, the tiger climbed on top of the device and lined up with its pre-lubed entrance. Everything was ready for them, they just needed the assigned scientist to oversee it all. He was a lower level employee and really had no idea what was going on or what they were exactly doing to this tiger. He could remember when it looked regular and was smaller. As more time passed it became all the more unique but was that a good or bad thing. Being tasked to watch him breed and ensure that the samples were collected for further testing had an effect on them. Anticipation was welling up within the onlooker as he watched the feline prod until its tip slipped in.

The tiger pushed his hips forward and his length was shoved into the artificial hole. Though far from natural, the device was outfitted with various features to "encourage" the subject. The most apparent was the warmth set to simulate the insides of a heated female. Stimulating the tiger's cock were smooth nubs, something to ensure release. A few shallow humps were given to the device before a stronger thrust pushed the entirety of the tiger's length inside.

Now fully hilted, the tiger's hips were rocking back and forth. Heavy pants were starting to come from the creature, conveying the pleasure it felt. The mount was built to withstand the rough treatment that a rutting tiger would give it and was further reinforced beyond that. The sharp claws dragging along the surface didn't leave a scratch as they moved upwards. They wrapped underneath, keeping the "tigress" close to himself. Now having his mate in place, the tiger proceeded to hump even faster.

Though the glass was thick, the scientist was able to hear the action taking place on the other side. The combination of heavy pants and wet slapping was equally arousing and intimidating. There was a job to be done but that didn't stop the onlooking fox's cock from getting erect in his pants. His arousal only grew stronger as the tiger continued penetrating the mount with clear intent to fill it with his seed.

He had to actively remind himself that there was another part of his job. The fox began taking notes on the tiger's performance. Based on the data that he was recording, the tiger's prowess was increasing at a steady rate. It showed in the way he was really pounding into the mount. The wet sounds had gotten even louder from the precum that joined the lube in providing a slick surface to help with thrusting. This was used by the tiger and he began slamming his cock in with greater speed.

Noticing the signs, the scientist acted. There was a panel that was directly linked with the mount. It was responsible for the mount's interior being warmed ahead of time. But it could do more than that. Seeing that the feline was nearing its release, the fox felt it was a good time to increase the interior's tightness. The dial was cranked up slowly to not throw off the tiger's stride. A grunt came from the beast upon noticing the tighter hold. The tiger's balls were slapping against the mount's front, the sound reaching the fox that had his eyes glued to the scene before him.

It ended with a final thrust and the shaking of the tiger's body. The tiger's body was kept in place as a thick spurt of cum flew from the cock's tip. There was a siphon inside that was already working to collect the cum. With every spurt that came ever the first, the container was being filled up. In addition to breeding prowess, the tiger was also producing greater amounts of semen. First they were collected in vials, then bottles, and now they were up to containers equivalent to a quart each when filled up.

Being satisfied for the time being, the tiger dismounted and a thick rope of cum kept the tip and mount connected for a bit. The meaty feline cock slid back into its swollen sheath. So used to the routine, the tiger didn't need any lure to bring him back to his dwelling behind the doors that were shut when he passed them. The fox wrote down the last of the results. With the doors shut he could get up and enter the room behind the glass through a secured door. The smell of breeding was still heavy in the air. It was also his job to secure and bring in the "results." It was hard to keep his composure when he reached down to collect the containers. Leaning down low enough to see the mount's stretched state and messy interior. The scent of cum poured in his nose and the heat of fresh tiger reached his fingers through the containers' glass. Keeping his composure and reminding himself that there was a job to be done, the fox secured the containers to be examined by his superiors.

***

Things had changed a lot in the months that passed. More experiments were run based on the results. The tiger was given more capsules that were hidden in his meat or injected with serums after being tranquilized. These certainly changed him but none more than the most recent one. He had been under the effects of heavy sedation during the process but when he came too the tiger felt...different. There was also something around his neck. A red collar that had spikes like the kind a dog would wear. The feline tried for a while to get it off but it wouldn't budge. He figured out that it wasn't because the collar was tight but because it was essentially fused to his body. This wasn't a truth he figured out on his own. The tiger heard the scientists speaking. He could understand them fully. Apparently they had made a breakthrough and the collar played a big part in that.

Through listening to the scientists talking to each other the tiger learned more about this place and the world outside. A world he had no idea existed. These hard grey walls were all he had ever known and outside of the meat he was given, the only entertainment offered to him were those breeding trials. It may have been enough to satisfy him before but with his newfound intelligence, the feline understood there was more to life. He wanted to experience it for himself. He wanted to get out of here.

While some things had been learned through listening to others, some other things were just innate. One of those innate things was the tiger not talking while being observed. Though not certain why at first, the tiger hid the revelation that he could speak their language now a complete secret. Looking back, it was the best choice he ever had. Another thing he noticed was the fox that always observed it. He was alone and always seemed a bit distracted. Perhaps he could use that to his advantage?

It had actually been a while since his last breeding session. Being without it and having nothing to do but lay about was getting boring to say the least. Thankfully the day came when the doors were open, just when he was about to go crazy from doing nothing. As per usual, the mount was ready for him and wafting the alluring scent of a female tiger in heat. While still enough to get him erect, this was no longer enough to sate him. Even when he came and gave them their precious samples, the tiger felt...unfulfilled. He didn't understand why at first but came to understand that what he desired was an actual body, not some artificial replica.

All the same he had to plan the part in front of the scientist. Though different from the others, he was still a part of the facility. Couldn't run the risk of ruining his possible means of finally escaping. Playing the part included getting atop the mount and pushing his cock inside of it. That cock in question was even bigger now, approximately 20 inches since the fox last spoke aloud while documenting. It was certainly felt by how much tighter the mount had become in its base start. Its pre-lubed state and warmth was something he still appreciated. His cock was pushed into its hilt and he began thrusting against that tightness.

There was no reason he couldn't enjoy this one. It was going to be his last after all, why not go all out? Forgoing his usual method of gradually picking up the pace and force, the tiger started out with rough tugs and pushes that slammed all of his cock in each time. It did feel good. It felt amazing really. He was still a creature made of flesh and going much longer than usual without a chance to drain his bigger balls had its effects on him. Panting heavily and slapping his balls against the mount was his way of expressing his feelings instead of saying it aloud.

At the very least he could pretend that this mount was another living creature. Female, male...he didn't care. What he wanted to feel was a squirming body. Someone alive and warm. How they would moan from his cock reaching so deep inside of them. The smacks of their bodies coming together. These thoughts fueled his actions. Growling as he did it, the tiger began unleashing ropes of his thick seed. He didn't need any more tightness to get him off, the mere fantasy was enough to make him blow a big load. Speaking of which, his seed was flowing into the containers below but it was too much. The containers couldn't be rotated fast enough. They were being overfilled with his spunk and it was spilling through the gaps and onto the floor. The tiger heard a gasp from the glass and knew it was the fox reacting to all of this.

He expected the scientist to simply write all of this down. But the fox picked up a phone and began talking to someone. His voice was equally excited yet frantic. He briefly explained the situation then seemed surprised by the response he was given. The fox even asked if the person on the phone was sure. But he quickly winced, likely getting yelled at by whoever was on the other side.

"U-understood, sir. I'll activate it," the fox said. He put the phone down and looked down at the console in front of him.

The tiger had just finished blowing his stored up load and was curious to know what that was all about. His answer came when a button was pressed from the other side of the glass. Immediately the tiger began feeling strange. A rush was sent through his body, traveling along his body's length until it was focused on his loins. His cock was still out of its sheath and fully erect. A groan came from the tiger as the mount was getting even tighter. Had the fox calibrated the mount's tightness? No, the creature could feel it. Along with the intense warmth and tingling, he could feel that his cock was expanding even further. At the same time his balls were feeling heavier too. The tiger groaned from the feeling. It was pleasurable but also strange, like countless tongues on his length all lapping in different ways at the same time. It was hard to keep up with and a shroud of unfocused pleasure took over.

From the fox's perspective he watched it all happening. He was given an idea of what to expect from the subject but he performed beyond that. So he made the call and was told to activate the collar. He only had a general idea of it. It was connected to the tiger's body in some way and was making this happen to him. The fox watched it all from a distance, the tiger's cock and balls growing even bigger. He wondered if it hurt the subject. The tiger was still latched onto the mount, his cock buried inside. But as the length continued expanding more of it was sticking out of the mount. He surveyed until the expansion came to an end. Undoubtedly the feline's cock had gotten even bigger but his balls...the white fur-covered testicles were huge. Each was the size of a prime watermelon and were just short of being dragged along the ground.

The tiger was still reeling from the experience. As the tingling faded there was one thing he knew for sure. He needed to breed further. His newly expanded balls felt so heavy with seed that needed to be drained and his cock was aching to grind against the warm walls again. He began rocking his hips again, huffing and even growling as slammed his even bigger cock into the mount. Precum was already being spurt inside of it and it was coming out in the same way the cum had been collected. It was already too much for the device to take. And that wasn't to mention the mount itself starting to rock and groan from the thrusting's force. There was so much that the precum was also leaking out and dribbling down the balls it all came from.

Rutting the device so quickly and roughly, the tiger felt himself approaching another climax. That didn't stop him from maintaining the pace. All he cared about was taking care of this burning need within him. This time the tiger roared as he came even harder than before. He continued rocking his hips as ribbons of cum were firing from his tip. His huge balls were churning as huge amounts of spunk were being pumped through the swelling length. The mount's means of collecting cum couldn't keep up. As the clinging tiger continued to thrust and expel his seed, the excess was spilling back out but the tiger's size did a good job of plugging up the entrance. This resulted in the mount gradually expanding. Aside from the tiger's huffs the groaning of plastic and metal could be heard. The bolts were straining and the beam it was all posted on was starting to falter as well. It all ended with a defending "boom" that made the fox fly back in his seat. The mount was pushed to its limits. The device popped like an overfilled balloon and a huge splatter of cum was released. It covered the observing window and the fox was unable to see inside.

He had no idea what to do. Should he call his superior? But how would he explain all of this? Undoubtedly the breeding mount had been destroyed and any chances of gaining an uncontaminated sample had been dashed. The view into the other room was completely obscured and there was no sound to be heard either. Putting the fear of being fired aside, the fox grew concerned about the tiger that he couldn't see. The breeding mount exploding like that was completely unexpected but it was also dangerous. Luckily he was protected behind the glass but how was the tiger affected? He could have been hurt by any flying parts of shrapnel.

From a place of concern, the scientist made the conscious choice to approach the door that led into the other room. He opened it slowly and gasped from the sight that met him. Just as he expected, the mount was mangled from it exploding from the inside out. Seed had splattered out in all directions, not just on the windows but all over the other walls, ceiling and on the floor as well. The scent that lingered after a breeding session was even stronger now thanks to the fresh seed that was everywhere.

The only unchecked favor and most important was the tiger. There was no sign of him. Theoretically it should be easy to spot a large beast but the fox couldn't locate him. It didn't help that the scientist was a bit distracted by the sights and smells of potent feline seed all over the place. The question of the tiger's location was ultimately answered for him. One minute he was standing on his two feet and the next he was pinned down by a great amount of weight. He groaned from being suddenly tackled to the floor. When his vision cleared the fox found himself face to face with the very beast he was looking for. Of course his immediate reaction was one of fear.

"Let's skip the screaming part."

The fox did stop. He blinked and wondered if he hit his head too hard. It was as if the tiger just spoke to him.

"I would say something like "cat's got your tongue," but that's way too easy."

There it was again!

"Y-you can talk?!" the fox exclaimed.

"Oh, I can do a lot more than talk. But you already know that," the tiger said, his tone of voice being unexpectedly flirty. "I just knew better than to go talking in front of you and the others. At least until the time was right."

"I can't believe it. You can talk. You're intelligent," the fox stammered.

"I was intelligent before, but you I get what you mean. You know...all those tranquilizers and needles jabbed into me. Not a big fan of them. I could easily take my anger out on you. Yeah, it wouldn't be hard to either rip you apart or maybe even swallow you whole."

The fox gulped and began to tremble under the tiger's paws.

"But I think we can help each other. I'm trying to get out here and you're gonna lead me out of here."

"I uh..."

"You're fired anyway. I've seen you from behind the glass. The way you're always being pushed around by them. I've also seen the way you look at me. You just loved watching me breed that mount, didn't you?"

That's when the fox turned his gaze to the mount. "It's completely wrecked now..."

"Wrecked. Yeah I did that. I like the sound of that too. You know I've been thinking of names to call myself and you gave me a great idea. Wrex. What do you think?"

"I uh... Why did you break it? You must have done it on purpose," the fox surmised.

"Oh yeah...that. Aside from getting out of here another thing I want is a hole. A real one. And it looks like I've got one right under me."

"Y-you mean you..."

"Don't act like you haven't thought about it. You're probably been picturing yourself as that mount when I got on top of it. Well I'm tired of that thing. I need something real to sink my cock in. Let's help each other out. One quick fuck and then we're out of here." The tiger's inviting tone of voice was one thing but as if on cue, the fox became aware of a masculine yet distinctly wild scent coming from the tiger. Being fresh from a rutting session, the large beast's body smelled of musk that was exciting the fox.

"So do we have a deal?" the tiger asked.

The fox gulped again but nodded.

"I'm gonna need more than that. Prove it by...licking my paw. If you don't, I'll have to make a little snack out of you." The tiger ran his tongue over his fangs. A sight like that was intimidating enough from a regular tiger but this was no ordinary tiger. The fox had played a part in creating this creature that was now fully sapient.

The fox was ripped from his thoughts by a paw that was held mere inches from his face. Even with just one paw on him now, the tiger still had him pinned down and unable to get up. Did he really have a choice in all of this?

Having it so close, the fox's sensitive nose picked up on the alluring scent that was attached to the paw. He didn't want to admit how easily he was succumbing to his own desires. The paw seemed to be teasing him, not just the musk attached but also its size. A paw like that would have no trouble smothering him if the tiger really tried. For some reason that just made the scientist all the more excited. Swallowing the last remnants of his pride and better judgment, the fox extended his tongue and made contact with the paw.

All it took was a single lick. Wrex felt the tongue lap over his pads. It was a soft touch but the fox shivered from what he tasted. Though a simple act, it had a great effect on the fox that had fought hard to keep his thoughts pertaining to the tiger in check. Just a lick was all it took for the floodgates to open. Another lick came right after. Wrex chuckled and eased his paw down. Having the pad pressed to his muzzle, the fox got to work. His tongue was running all over the pads and even in between them. The taste of sweat got the fox hooked and he didn't mind the bit of dirt that got on his tongue. As the paw grew wetter from the licking, Wrex was looking first satisfied then excited as well. The sensations from having his paw worshiped was more than enough to make the tiger's sheath stir.

The fox's want for more overpowered everything else at the moment. He sought to lavish the large paw as best he could. In addition to lapping his tongue all over the slightly rough surfaces he also slid in between them when he could. The musk in those crevices was especially potent and there was sweat there too. A moan came from the smaller male when the taste reached him.

When Wrex felt satisfied with the paw cleaning, he eased it up. But the fox wasn't done just yet. Replacing that one was his other paw. There was a moment of lightness but the licked paw was pressed back down on the scientist, its dampness being felt through his shirt.

This paw was pressed to the fox's face with more weight and force than before. There was no time wasted in huffing directly from it. The pads were damp from sweat and heat was radiating from them as well. Just a few deep breaths was all it took. Giving in further, the fox got to licking like he had before. A satisfied sound came from Wrex. He was enjoying the control he had over the scientist who observed him for so long. The fox really showed his dedication by licking all over the digits. A moan came from him while doing this. Then he began to suck on the digits. After doing this to the first he moved on to give the others the same treatment. Swirling all over, his tongue cleaned away the dirt and sweat that clung in the tightest spots.

"Enjoying yourself?"

The fox was snapped out of his daze. He was taking a moment to process what he had just done. It was just so easy to drift off while licking and huffing on those paws. Its effects had taken hold of his mind and even now he was wanting for more. Both paws were wet with his spit though they were still musky. It would take more than a tongue cleaning to wash the scent away, no matter how thorough it would be.

"Just stay right there. I've got something you're really gonna love."

The fox did just that. He kept himself in place, lying flat on the floor while the tiger's weight eased from him entirely. The most he could do was observe as the feline turned himself around. That gave the scientist a full view of his balls, still in their expanded state and looking even heavier up close. When he was fully turned around and in position, Wrex sat himself down in a way that his balls were all but smothering the fox. Just like before, it took only a few sniffs of the wild musk for him to become hooked. His better judgment had been tossed aside entirely. He just couldn't help but embrace it all. The feeling of warmth, the scent pouring into his nose, and the desires he harbored for a long time. It could no longer be denied or ignored.

"Get that tongue working," Wrex commanded, his voice having an edge to it. The fox didn't need to be told twice nor did he need much reasoning.

Complying with the command, the previously nervous employee put his tongue to work by dragging it against the balls as best he could. His manner of doing so wasn't smooth and hardly controlled. He was simply licking wherever he could. There was a lot of area to cover. The sack itself was like a ginormous pillow that he could nuzzle against and possibly fall asleep on. The mere idea excited him further.

Wrex felt the tongue working on his balls. The size difference between them meant there was only so much that the fox could lick. It seemed his balls were more sensitive now. Pleasure was coursing through him and it made his cock throb hard all over again. He could definitely get used to being worshiped like this. While still not sure how or for what purpose, Wrex knew he was a prime stud that should get his way. He felt that tongue moving even further, working to clean up more of his sweat and even some of the cum that had gotten on his fur. The tastes of it were clearly appealing. The fox couldn't stop moaning if he tried.

What the fox couldn't reach with his tongue, he used his hands to make up for it. He covered more area overall, sweeping in wide circles and brushing his fingers through the damp ball fur. Doing this roused out more musk for him to take in while also earning him some hums from the tiger. Wrex was getting all of the direct pleasure from this. Waves of light pleasure were radiating throughout the rest of his body. His cock was starting to leak again, dripping more of precum. Not having a mount to deposit the fluid into, it was left to dribble onto the fox's clothes, soaking them in his scent.

"Yeah, get deep in there..." Wrex put more of his weight down. There had been just a bit of breathing room for the scientist but the sack coming down even more closed that distance. Along with the musk becoming even stronger, the fox found it was much harder to breath, nearly impossible. The little air his lungs found was tainted with tiger musk and those balls were being rubbed against his face. The wetness of his own spit and the remaining sweat was rubbed back onto his muzzle. Though it was getting harder to breathe properly and his lungs were straining for air, the fox was still moaning.

Still needing him conscious for the time being, Wrex decided to ease up. The fox was able to take in more than just a bit of air at a time. He was still a bit dazed from the whole experience and needed a bit of time to collect himself. Wrex got up and turned himself around again. He took advantage of the fox's current state, making good use of his claws to tear away the scientist's clothing. There was no afforded to process this. When the fox's bottoms were torn away completely he was effortlessly flipped onto his back.

Coming in from behind, making a low rumbling sound that came from deep in his chest, Wrex eased his head down and drew his tongue over his prey's ass. The touch made the fox jump. A heavy paw came back down to hold him in place. Its weight and the pricks of unsheathed claws against his skin were more than enough to keep him from escaping. More licks came. The massive tiger's tongue was of course large as well. It was sweeping over his glutes at first, ruffling the fur that covered them. This was Wrex's first time working with a living partner and he was taking his time.

Being guided by his instincts, the tiger continued licking until his tongue began to part the fur covered mounds. Knowing that he was onto something, the tiger continued pushing until he made contact with something smooth and warm. The fox was quick to moan from the touch. Grinning while his tongue was still extended, the tiger's next lick was directly over the other male's rim. The action sent a jolt through the fox. It was large, hot, and the power behind it ensured that tingles were forced into him. On top of it all were the bristles that covered the tongue. Being stimulated far beyond what he expected, the fox groaned and balled his fists.

Things escalated further when the tongue was slowly spreading him. A louder groan was forced out of the fox. There was little he could do to stop its entry. At least the entry was done slowly. This was done less for the fox's own sake and mainly because of Wrex's own curiosity. He didn't want to rush his first time with a real hole. Working his way inside, the tiger was already lapping against the walls, getting a taste for them and feeling them clench down in response. The constant moaning was a clear indicator that he was doing this right.

Spurred by his own excitement and need to finally penetrate something alive, Wrex worked to prepare the hole. His licking became more intense and more of his tongue was shoved in without warning. Another loud groan came from the fox. A mix of pain and pleasure shot through him. The pain was already being eased by the licks but it had made him tensed up. Powering through the sudden tightness, the tiger's tongue was worming in deeper while also stretching the passage's walls even further.

The tiger's methods were effective. He was using his saliva to lubricate the fox's rear. The fox wasn't prepared for the feeling of hot saliva being smeared all over his insides and even dripping down his balls. As the deep rimming continued, the fox was feeling nothing but pleasure and also soaked under his tail. This lasted until Wrex pulled his tongue free. The fox was left feeling "hollow." His rim had been spread further than it ever had been before.

Everything was moving so fast. All of a sudden there was a weight on his back and a prodding against his tailhole. The fox gulped when realizing that he was going to be taking the tiger's maleness. It was already big but the collar's effects had made it even bigger. While the expansion wasn't as extreme as the balls, the feline's length had still expanded to just short of twice its original size. Even with all that licking and the slathered state of his ass, the fox wasn't sure if he could take it...

They were going to find out together: as soon as he was on top, Wrex made the first instinctual push of his hips that shoved his cock inside. The spit helped greatly with the insertion and the tiger's precum being all over the tip was the extra little something the fox needed. It was going in with a surprising amount of smoothness. As the inches disappeared from sight, there was a bulge that had formed in his stomach before expanding further. The fox couldn't believe that it was sliding in. How was this possible? Was the saliva or the precum. Now that he was really taking notice, both were feeling especially viscous. Whatever the case, his body was taking in the immense length with hardly any trouble.

That's when the first thrust came. The fox had assumed too soon. That smooth entry had been just for the first half of the feline's cock. It seemed that a roadblock had been reached, the bulge in his stomach was unbelievable in itself but there was more to take. Growling above him, the tiger made another push with his hips. Something inside of the fox was forced to open up and this made him cry out. His voice echoed through the room as another mixed wave of pain and pleasure overtook him. There was little else for him to do other than ride it out. A blinding flash of pleasure came from his prostate being rolled right over and kept pressed down. Eventually the tiger bottomed out and he grunted from the tightness that he felt around his cock.

This was how it was supposed to feel. This heat, the pulsing against his cock, the sounds that his "partner" was making. Speaking of which, his weight and paws locking in underneath kept the fox from going anywhere. The first one was always special. He was eager to get started. Just having his cock sitting in the other male's depths was driving him crazy.

To the fox's relief, the thrusting was done in a steady and controlled manner. Wrex wanted to get a good feel for a real hole and spared the fox from him pounding in fast and hard for the time being. That didn't mean it was easy for the vulpine. His body was already shaking from the many sensations that were forced into him. The thickness and length grinding along his walls, and those barbs that dragged along his extra sensitive spots. A moan came out when it was pushed back in. Though not fast, the thrust was still forceful enough to push his body forwards if it weren't for the tiger's front paws keeping in place.

Wrex was getting a handle on thrusting into another living being. He felt the smaller body being pushed a bit by his own actions. The fox was moaning and whimpering out, unable to control his voice or his body's reactions. The most he could do was just hold on while the length and barbs ground over his prostate again without mercy. His stomach was stretched far beyond its usual means by the flesh being pushed in so deep. And then the tiger's strong and large pelvis would come in, smacking roughly against the fox.

It wasn't right, morally speaking but the fox was loving this. He was being used by a tiger. At one point the beast had been like any other feral creature. And even then he felt things he shouldn't have about the feline. As much as he wanted to deny it, the scientist was living out his greatest fantasy. His moaning was already loud but it changed noticeably, laced with an undeniable pitch of ecstasy. It wasn't as if he had a choice, but the fox still left himself completely open and at the tiger's mercy.

Wrex felt the fox loosening up in his grip. Grinning to himself he kept pushing his shaft in as deeply as he could. His crotch made repeated contact with the fox's backside and his large balls came swinging in as well. Having all of his cock buried deep inside of a hot and squeezing hole...it was so much better than he imagined. He couldn't get enough of it either. Another deep thrust led to the hole clenching tight. Powering through the increased tightness felt so good, spurring his hips to naturally buck forwards.

From all of the pleasure coursing through him and the churning of his extremely fat balls, precum was freely spilling from the feline's cock. It was coming out in large amounts, both expanding the fox's bloated stomach even faster while also spilling out. The heat and stickiness of tiger precum was clinging to the fur of the fox's stomach, down his legs, and his loins were slathered in the stuff as well. The abundance of this precum also allowed Wrex to thrust in faster from then on. This came with louder thumps from their bodies connecting. Wrex's cock was making a series of deep slurping sounds when it was tugged about. Along with the added speed, the tiger was also putting more of his weight down. The fox found himself being pinned in between the larger body and the floor.

Wrex had plenty of experience in breeding the mount but there was some nuance to having someone else to penetrate and dominate. The fox wouldn't stop squirming against him. In order to remedy this issue the tiger took hold of his prey. His instincts compelled him to do so. Having the fox's neck fur held in his jaws helped keep him in place. Maintaining his stride and grunting against the fur, Wrex listened to the other male's moans and gasps. The fox's hands were flailing a bit and his body was starting to shake more. Forcing these reactions from the scientist brought a surge of pride to the tiger. This was it. The power he held over someone else, plunging his length in deep and getting moans in return. He was driving the vulpine crazy without putting in much effort. Just picking up his pace somewhat had been enough to make the soft hole clench down harder and more frequently.

Those clenches were because of the fox reaching his limit. Purely from having his insides stroked and his prostate flattened from the length and girth, the fox could handle no more. Without touching himself once the fox achieved an intense orgasm. His cum came shooting from his cock with unexpected force. From behind he was still being thrust into, making his climax much stronger than it usually would be. Ropes of his own seed came flying out to make a mess of his own belly and the flooring beneath him. There was no time afforded for him to come down from the lingering orgasmic feelings. He was still being roughly rutted and could feel the tiger's cock throbbing against his stretched-thin walls.

Wrex was thrusting in even faster now. His pants came harder as well. The fox felt hot puffs of breath against the back of his head and ears. Drool was leaking from the tiger's mouth, wetting his neck fur even further. Putting more effort into his actions also rocked the fox's body with more force in return. His voice was straining at this point, being just outmatched by the deep and rumbling growls that came from deep within the beast's chest. Wrex was being driven further by his own desire for more pleasure in combination with his instincts. Feeling the approach of his climax, it just came natural for him to slam his cock in with all the power and speed he could muster...

For a moment the fox was snapped from his daze. He recalled how much Wrex had released before. How the mount swelled before bursting. The feline's balls were still huge and he was going to be released at any moment. A sense of dread came over the fox but it was already too late by then.

In time with another hard buck and slam of every inch deep inside of the fox's passage, there was a sudden rush of heat and thick stickiness. Cum was firing from the tiger's cock with force and in huge amounts. It was already too much for the fox to take, a large amount of it was spilling back out like the precum had. It was flowing out and down his backside: his legs, thighs, and balls were made even messier than they had been before. If that wasn't enough to endure all on its own, Wrex began thrusting while cum was still pouring from his length. Those oversized balls were pumping what seemed to be endless waves of spunk. Thrusting into the same hole it was being pumped into produced a loud messy noise and the seed came splattering out all over the place, not just soaking the fox's backside in the musky substance but also the tiger's own belly and crotch. Another mess was added to the already ruined observation room. The cum was splattering from the fox's hole with so much force that the floors and nearby walls were being marked. Any surfaces that hadn't been coated before were now.

While a torrent of cum was spilling out of the fox, there was still an immense amount that had been pumped inside. The moment Wrex's climax began, the fox's stomach was made to expand even further. Filling it like a balloon was a hot and thick substance. Its heat was overtaking the rest of his body. It was making the vulpine tremble and whimper. He was thankfully spared the fate being overfilled like that mount had. Maybe it was the load the tiger blew earlier or maybe Wrex had made the device explode like that on purpose. Just how intelligent was the tiger now?

The tiger's cock was still throbbing hard and shooting huge gushes of feline spunk. Wrex had stopped thrusting. Another groan was released against the fox's scruff as the tiger just enjoyed the rest of his long and intense orgasm. He kept the fox pinned down underneath him, ensuring his seed was given to the other male. It was even better than he imagined and he couldn't wait to do it again but not here and not with that mount...

As the feline's loads grew thinner and weaker, Wrex pulled his cock free and released the last of it all over the fox's back. From head to toe the former employee was marked. The scent of the feral was stuck to his fur and the remnants of his clothing. He couldn't move, not just from the bloated state of his belly but also there was a weakness in his limbs that made it almost impossible for him to stand at the moment.

He was thankfully given some time to get a hold of himself. Wrex decided to groom himself. His rough tongue slid along his own body, collecting his own sweat and cum on his tongue. A few purrs came out as he did this, especially when the tongue was on his sheath. The feline was completely satisfied. With his shaft completely tucked back into its pouch, Wrex noticed that his balls were shrinking. He felt no pain or discomfort, just an intense tingling. When it came to an end, the tiger's sack was back to his usual size, still much larger than any normal wild tiger's.

"Hmm..." he pondered to himself. "What was all that anyway?"

The fox groaned but found that he was able to speak. "It's the collar. Its permanently linked to you. I activated it but that weren't the results we expecting. It was suppose to enhance your body for a short amount of time. Make you bigger and stronger. But when...that happened."

"An unexpected perk," Wrex said with a chuckle. "Can you do it again?"

"N-now that it's been activated, you should be able to control it in theory... It responds to certain natural triggers. The need to protect yourself or hunt down prey that may be risky or..."

"Or finding a hole you want to stuff your cock in. I get the idea. I can make good use of this," Wrex said. "Alright, nap time's over. You're leading me out of here right now. It's either that or getting eaten and I don't mind some cream with my meat..."

The fox did know a way out that kept them out of sight. They met some roadblocks but the large and powerful tiger had no trouble forcing his way through until they were outside. Left groaning from the heavy state of his belly, the fox leaned against a chain link fence while Wrex got to climbing.

"Thanks for the help. Don't wash my scent off it, you want something to remember me by," the tiger said with a chuckle. He had no trouble scaling the tall fencing and he jumped to the other side with ease. Touching down on the hard concrete with all four paws, the now free tiger raced off and he didn't look back. He didn't know where he was headed but there was a hole out there and it wasn't prepared for him.
