Funny story, when I started in on this one I was worried there wouldn't be enough to it to make a decent-sized chapter, and, well, here we are. Turned out to be one of the longest ones I've done. Makes sense though, I love the R&D chapters since they really offer a special opportunity to be weird and creative. So, yeah, this one does get a bit weird at parts, but hopefully in a good way. Just heed the keywords and we'll be fine. :)

Sorry for missing my usual deadline by a few days, as I said, it just kept going, and as always, enjoy! And thanks for reading!

______________________

Awkwardly twirling a pen between her fingers as she hurried as fast as her chubby little legs would take her, Belle led a pair of workers, a rhino and a donkey, through the halls of the R&D department. As opposed to the jittery beagle, the workers had fairly ambivalent, even bored expressions as they each carried a semi-conscious, wrist-cuffed, ankle-cuffed, ball-gagged rabbit draped over their shoulder. The closest thing to conversation the small entourage shared was an occasional smack from a worker to their respective cargo's rear, attempting to discourage any irksome struggling.

There wasn't anything specific making Belle nervous; more than anything she was just hoping to get her job finished before Marcus showed up.

No, she thought, shaking her head. Not Marcus, Doctor Marcus.

To most, that was a simple mistake, but for Belle, it was the reason why she was so skittish. On her best days she was, at a minimum, an easily flustered mess, but ever since the diminutive chihuahua was given the reins to the R&D department, she had been a complete wreck.

For the most part, Dr. Marcus was nice enough. He just had something of an... uneven temperament. Whereas his predecessor, Dr. Crane, had been nothing but kind, patient, and polite, the little dog was intense and unpredictable. Something simple like getting his name wrong was equally likely to get a polite correction as it was to get a shrieking tirade.

The reason why he was like that was something of a recent mystery; he was, at worst, occasionally impatient when he was Dr. Crane's assistant. Whether it was shock due to the old bird's death, the possibility that Dr. Crane's influence somehow kept him under control, or the stress of being put in charge of the whole facility, something in him had changed.

Most of the other workers just rolled with it and didn't seem worse for wear, but for a meek little wallflower like Belle, it was making life a living hell. Granted, she wondered, given where they were, perhaps it was appropriate. At least things seemed to be getting better as time went on. With any luck it was just a matter of avoiding him until he had time to even himself out. Unfortunately, the fact that she had been promoted to be his assistant made that a bit of a challenge.

Totally lost in her thoughts, Belle stopped short when she passed by a door labeled '337', causing the rhino and donkey to collide. She blushed, mumbling something in apology, and hurried to get the door, holding it open so they could carry their passengers through. Briefly looking around to make sure Marcus... Dr. Marcus was nowhere to be seen, she hurried inside as well, making absolutely certain the door locked behind them.

Room 337 was a fairly typical experimentation area, being extremely sterile with plain white floors and walls, as well as enough gently humming fluorescent lights to keep everything brightly lit. Several fully stocked tool cabinets peppered the room near the walls, scattered about haphazardly, though what really stood out were the two objects sitting in the middle of the room. Each object consisted of a thick cylindrical base with a set of four sturdy legs angled outward, a thick, cushioned mat at the top, and a small screen and keypad on the base. All told, they looked like little more than futuristic sawhorses.

"Oh, um, Jeremy, please get set up on the right, and Moe, you can take the left," Belle timidly commanded. Snorting in reply, the rhino, Jeremy, did as he was told, separating the male rabbit's magnetically locked wrist-cuffs and ankle-cuffs, then dropping him belly-down onto the sawhorse's mat. Too terrified to fight back, the rabbit simply went limp as the cuffs were secured to the sawhorse's legs, stretching all four of his limbs down as far as they would go, firmly holding him in place. Since the mat ended just above his crotch, his round balls were completely exposed, dangling between his forcibly spread legs.

The female rabbit put up a little more of a fight, flailing with sheer panic, almost managing to claw out one of Moe's eyes with a wild slash. Having finished with the male, Jeremy ran over to help, easily subduing her together. In moments she was left in the same position as the male, belly-down, limbs tightly stretched to their limits, magnetically locked to her sawhorse's legs.

With that all settled, Belle stepped forward to perform her inspection. She looked over the male rabbit first, admiring his slightly plump physique, pure white fur, long floppy ears, full, round ass, and cute, perky tail standing straight up into the air. He was visibly shivering, which, given his situation, wasn't terribly shocking. The giant, red ball gag stuffed in his mouth did keep his fearful begging muffled, at least.

After making a few short notes on his file, she stepped forward to get a closer look at his rear. Using the blunt end of her pen, she lifted his small, but full scrotum out of the way, revealing a caged bunny cock hanging down toward the floor. The cage was a basic four inch long cylindrical grid of smooth, thick wires, which given the six inch length noted in his file meant there was nowhere near enough room to comfortably grow erect. Not for lack of trying, given that she could see throbbing flesh clearly swelling through the gaps between the wires. Holding the cage in place was a ring locked around the base of his nutsack, as well as by a ring pierced through the tip of his dick and looped around one of the wires at the tip of the cage. That last part was Belle's idea; since he already had a Prince Albert piercing upon arrival, she figured they may as well make use of it. With the PA piercing secured as it was, he wouldn't be retreating back into his sheath again anytime soon.

Checking down the rest of the list, nodding proudly, Belle flipped to the other subject's file and strolled over to inspect her as well. The female rabbit, unlike her partner, did her best to show a defiant sneer despite her ballgag. A sneer that quickly gave way to a fear as the beagle approached.

Looking the worried creature up and down, Belle first noticed the large, round pair of breasts the rabbit was resting upon, squished between her chest and the mat. She tapped a few buttons on the side of the sawhorse, and it quickly reformatted itself so the sections of the mat under her chest fell away, leaving one of the heavy globes dangling on either side of the central bar. A small weight pierced through each nipple swayed lightly with every twitch the rabbit made.

She was quite skinnier than her partner, though still well-built and curvy. It was difficult to tell from their position, but according to her file she was also a couple of inches taller than him. Her coat was a calico mix of white, black, and tan splotches, with a white-furred head and a pair of long black-furred ears standing straight up. The ears were doing their best to radar around, trying to follow Belle since the rabbit couldn't exactly turn her head to watch. Same as with the male, a large ball-gag made sure she remained mute.

With an approving nod, Belle walked around the rabbit to inspect her rear. Like her counterpart, the rabbit was kept chaste, though in her case she had a series of small rings pierced through her labia. A thin metal chain was threaded through the rings, also running up through a piercing in her clit, lacing her pussy lips shut tight. In addition, the two ends of the chain were welded together, making sure vaginal stimulation wasn't going to be a viable option. In spite of that limitation, Belle couldn't help but notice that the glistening cunt was almost dripping with desperate need.

Making a few more notes, Belle, checked down the rest of the list and smiled. She finished ahead of schedule, which meant she could get out before-

"Ahead of schedule again, very nice," said a voice Belle instantly recognized, causing her to scream as she tossed her clipboard in the air. As if predicting the over-the-top reaction, a diminutive chihuahua stepped out from behind one of the tool cabinets, nonchalantly catching the clipboard with one hand as he walked.

"WERE YOU THERE THE WHOLE TIME!?!" she gasped, clutching her chest.

"Mmhmm," he hummed back, staring at her with a wide-eyed, deranged smile, idly brushing away a stray lock of his unkempt red headfur. He gave the files a quick read-through and without looking up, continued, "I don't know why you're so nervous, Belle. Am I really so frightening?"

Hesitantly twiddling her thumbs, she mumbled, "No... No, sir, Mar-" Hearing the beginning of his name, the chihuahua stopped reading and instantly shot her a wild-eyed, toothy grin, giving more of an impression of a veiled threat than anything else. "DOCTOR Marcus! I mean no sir Doctor Marcus!!!"

With the correction, the little dog's hostility faded back into a warm, if not unsettling smile, and he resumed perusing the files. "Everything looks as ordered. Thank you, Belle," he said, tossing clipboard over his shoulder, letting it clatter against the floor, and approached his new test subjects. Giving a polite nod, Belle breathed a sigh of relief and followed the rhino and donkey out of the room as quickly as her legs would take her. She froze in place when she heard the chihuahua utter her name, slowly, but menacingly. "Belle. You haven't been dismissed. Do you, maybe, see a PROBLEM here?"

Nervously turning back to see the chihuahua standing between the rabbits with his hands crossed behind his back, Belle could only meekly shrug in response. He said nothing more, visibly twitching as he stared at her with his buggy, overly large eyes. With an exaggerated sigh, Doctor Marcus raised a hand up, holding it horizontally just above the female rabbit's ass, then lowered it several inches until it was just above his own head.

"OH! I'm so sorry, sir!" she contritely shouted as she finally understood the problem. In a flash, she ran to each sawhorse, using the panel to reprogram them to lower by several inches, putting them at a more convenient height for the little dog. Once she was finished, Doctor Marcus dismissed her with a wave, watching her like a hawk, continuously staring directly at her. She sprinted out the door at top speed, slamming it closed behind her, immensely grateful that it was finally over.

The moment the door was closed, Doctor Marcus dropped his crazed expression and burst into a fit of raucous laughter. He walked up to the female rabbit, throwing an arm over her shoulders and leaning against her, ignoring her vain attempts to scoot away. "I'm sorry, I know, I know, I'm a dick, she's just so high-strung! I can't help messing with her, you know! It's just so FUNNY!" He leaned in closer, adding, "Truth be told, she's the best employee I have here. I should be nicer, I should, I know. I wish it wasn't so FUN to mess with her, though! Ah, well." Clapping his hands together, he walked out in front of the two bound rabbits and turned to address them.

"Alright, enough fun, we should be getting started, yes? I'm sure you have plenty of questions, where am I, why are you doing this, and the like. I'm happy to say, NONE of them will be answered! I do think some introductions are in order, though. As you may have heard, I am Doctor Marcus. And you... I've already forgotten your names, so for simplicity's sake I'll just call you Subject Two and Subject Three," he said, pointing to the female rabbit, then the male. "You may ask, 'Why Two and Three?' That's easy. Because I'm number one." Giving a cocky grin, he pointed both thumbs back at himself, as his subjects silently watched on with a mix of confusion and disbelief. Disappointed by the lack of reaction, he sighed, "Come on now, that was funny, wasn't it? Come on, laugh!" He stared momentarily at his cowering test subjects, and stomped the floor, shouting, "I SAID LAUGH DAMMIT!!!" Jumping in fright as far as their bonds allowed, both rabbits gave weak, fearful, muffled chuckles through their gags and were relieved to see that the mad doctor's slightly saner expression had returned.

"Thank you!" he happily chirped. "In retrospect, I suppose that COULD be confusing... So the female can stay Two, and you can be... hmm..." he mused, gently patting the male rabbit's shoulder. "I'll call you Bunbun, how's that? There, Two and Bunbun! Wonderful! Where were we... Yes, right! Short version, we acquired you two as a couple, and seeing as how that's a bit of a rarity, I saw a fun little opportunity to do a bit of control group testing. My predecessor was pretty focused on mechanical devices and the like, and while I share that same interest, with gusto, my true focus is more... chemical..."

Holding his hand toward the front wall, he snapped his fingers and a pair of images appeared, displayed by an unseen projector. The image on the left showed a female rottweiler, barely able to stand with a pair of breasts easily the size of beach balls. The other image had an obviously distressed male horse, cock hidden in a small solid metal cage, trying his best to straddle his hooves around a truly massive set of balls.

"I'm sure you're curious as to why I'm showing you that. Traditionally, it takes a whole series of hormone therapies to produce those kind of results. I, however, have developed a much faster serum. You could say I like showing off my successes." Gleefully striding over to one of the tool cabinets, he briefly sifted through the contents before returning with a gun-shaped pneumatic injector in each hand. Without breaking his stride, he used one to inject an unidentified liquid into Two's rump and the other to inject Bunbun as he passed between them. Snickering at their startled squeaks as he returned up front, he made a show of ejecting the empty canisters, twirling the guns, and holstering them on the belt of his lab coat.

"That serum is now in your systems. In moments, you'll be matching our friends on the projector!" If the chihuahua was being honest, he had no idea what they had been injected with. Maple syrup for all he knew. By Hell's own nature, the only thing that was important was that they believed it was going to happen. The psychology of it all was the real fun for him. "Oh, look at that, you're already showing!" he cheered, kneeling at Two's side and tugging one of her nipples. She let out a small whimper as she trembled helplessly in her bonds, and sure enough, her breasts began to rapidly expand. Once they grew to roughly the same size as the rottweiler's, the growth tapered off, leaving a pair of huge, super-sensitive beach-ball-sized tits swaying idly underneath her. Bunbun, as expected, had experienced the same process, giving him an unbelievably large nutsack hanging off the end of the sawhorse, thoroughly hiding the small cage between his balls.

"Ah, quite lovely. To be clear, those are products that are already complete; they weren't part of your testing. I just thought you could use a few... aesthetic improvements. Mission accomplished, I must say! Anyway, you'll be testing... this!" He pulled a canister out of his pocket containing some kind of colorful mystery liquid and clicked it into one of his injectors. "This little serum, if it works correctly, will make you impossibly stretchy. Not as in 'IMA BE A SUPERHERO!!!' stretchy, more 'An orifice that could previously handle a pickle with ease can now park an aircraft carrier without any pain or internal damage.' For example..." To illustrate his statement, he gave a slight gesture upward, and a large motorized piston descended from the ceiling, giving a loud, echoing whir as it lurched into position behind Bunbun's rear. The bright red dildo mounted on the end of the piston made it clear it was a fucking machine, even though the fake dick looked more like a fire hydrant than something that could conceivably be used for pleasure.

Bound as they were, neither rabbit had any idea what the noise had been, though the madly grinning dog was made it clear they wouldn't like the answer. Happy to fill in the blanks, he snapped his fingers, changing the projected images to a live feed showing the view from behind, complete with a colossal shaft threateningly poised to ream Bunbun's ass. In unison, both subjects enthusiastically struggled, shouting muffled pleas through their gags.

"Now, now, not to worry! With this," he said, pointing to the injector, "Taking a pounding from a monster like that will be a BREEZE. For one of you, that is. The control won't be quite so lucky. Aaaaaaaaand since the machine's already behind Bunbun, looks like you'll be that unlucky one, sweetie." he said, playfully smacking the Two's rump as he made his way behind her partner.

"Before we start messing around with any alterations, I suppose we should get a baseline for what you can normally handle." Tapping a button on his watch, a shiny black goo oozed out of it, spreading up to his shoulder under his coat, completely covering his hand, as well as the watch itself. Within seconds the substance gelled, giving him a solid, slick, long latex glove to keep his hand clean. Smirking at Bunbun's nonplussed, cowering reaction, having watched all that on the video feed from behind, Dr. Marcus promptly slipped his latex-covered index finger into the unprotected tailhole. All at once the rabbit's entire body seized up, pulling uselessly at his bonds, able to do little else but emit a guttural whining groan. Two was no better off, silently watching the video feed, still dreading what 'Control Testing' truly meant.

"Hm. Not very well traveled, is it?" Dr. Marcus rhetorically asked as he tried to flex his finger in the clenching anus. "If it weren't for the glove I probably wouldn't have gotten THIS much in! Let's see if you can handle a liiiiiiiitle more..." With some effort he wrenched his finger from the fleshy hole's grip, added his middle finger, and gradually worked his way back in. He only made it to the second knuckle before deciding that was all Bunbun could handle. For the time being. The rabbit seemed almost relieved once the fingers were completely pulled from his rear, though the increased constriction on his caged member, buried snugly between his colossal balls, was a figuratively growing concern.

"Can't even handle two fingers. Noted. Now, let's see what the stuff can really do." Using his free hand, Dr. Marcus grabbed the injector and held it against Bunbun's rounded rump. A small hiss sounded as the canister emptied, forcing the serum into the rabbit's system with a slight pinprick. "I'm not exactly the patient sort, so I'm going to do something to help the whole process along," he added, retrieving a ping pong paddle that had several holes drilled through it from a tool cabinet. Seeing that, Bunbun could only brace himself for what came next.

A loud thwack echoed through the room as the paddle was brought down hard on his left ass cheek. The chihuahua hesitated after the first strike, decidedly interested in gauging the rabbit's reaction. From the muffled cry and curled toes, he had to assume he wasn't a fan. No matter, Dr. Marcus thought, it's not like he gets a say in the matter. Raining down a series of spanks across both cheeks, he occasionally made sure to directly target the winking star between the cheeks. Before long, a faint red tint showed through the white fur of the presented bubble butt, signaling to the grinning dog that it was time to relent.

Taking a moment to calm himself, he said, "There, that should do it, you should be all stretchy inside. What say we give your new capacity a try, hm?" Disinterestedly dropping the paddle to the ground, he held his gloved hand up to the rabbit's rear and pressed the whole thing between the round cheeks. The dog was almost shocked at how well everything had worked, since this time around, he easily slid his entire arm inside all the way up to his armpit so quickly that he barely managed to remain standing.

Bunbun was positively howling, unable to even remotely process the feeling of being filled to that degree, particularly without feeling any actual pain. More than anything it felt weird, maybe uncomfortable, perhaps even pleasurable, in its own way. Not that pleasurable was a good thing, continually denied as he was. He merely whimpered and did his best to adjust.

"Very, very nice! Excellent work, Bunbun," Dr. Marcus said as he regained his footing, pulling his arm out with a sucking, wet pop. "I think you're ready for stage two!" Before his sighing test subject could enjoy the feeling of being empty again, the dog gestured up toward the fucking machine. The machine instantly sprung to life and thrust its piston forward, burying the fire-hydrant-sized dildo deep into the gaping tailhole. Moving at a steady pace, the piston pulled out and thrust back in, slowly, brutally pounding his ass raw. More full than the male rabbit had ever believed possible, he resumed groaning. Not from pain, but pure frustration. Nodding in approval, the chihuahua took a few steps back and leaned against Two, enjoying the high pitched squeaks she made, watching her companion get stretched beyond any reasonable limits.

"That should keep your boyfriend busy for a bit," he flatly stated, "Or husband, or whatever. Already forgot. Not important. We need to have us a chat. As I'm sure you remember, you're going to be the control in this experiment." He stopped to wait for a response, but she was too transfixed by the video feed of the total reaming to focus on anything else. Snapping his fingers right next to Two's ear, he regained her attention. "WHAT THAT MEANS is that you'll be taking that little fella up your pretty little butt, without the assistance of the serum. To observe differences and all that." Her eyes widened as his statement finally registered, making her madly shake her head, pointlessly trying to renew her struggling and escape at all costs.

"I'll level with you here, I'm not a very good scientist, I couldn't really care less about proper scientific methods and all that nonsense. I have employees for that. Mostly, I just like throwing science at the wall and seeing what sticks. Heck, my title's really just an inherited thing. Shocking, I'm sure. But here's the deal, we both know what will happen to you without it. Won't be pretty, I mean. Lot of clean up. So, just do one little thing for me and I'll give you the serum too! Simple as that." The begging look in her eyes confirmed that she'd be willing to do anything, which was all he needed to see. "Alright then, here it is..." he said, fiendishly grinning. "Say 'Pretty Please!'"

Initially she did nothing, only looking totally confused. Given everything else she'd experience since arriving, it was hardly a surprise that he wanted something bizarre, yet simple. It didn't take long for Two to shout a muffled, "Pwiee Pwee!" through her gag.

"Pwee pwee? I don't know what that means."

"Pwitee Pwee! Pwittee Pwees! Pwittee PWEEEES!!!" she shouted multiple times, growing more frantic, watching the piston pick up speed, mercilessly pounding Bunbun's hole.

Letting out a laugh, Dr. Marcus stopped her, saying, "I was just messing with you! Come on, I'm not a MONSTER, right?" He didn't bother waiting for an answer, instead ejecting the spent vial from his injector, replacing it with another full one from his pocket, and injecting it into her rump. As she winced from the pain, closing her eyes in some mild degree of relief, he added, "Don't settle down yet, there's still the prep work!" Picking the paddle up off the floor, he used it to relentlessly batter her ass cheeks, drowning out the wet thumping of the machine with the sounds of repetitive, painful smacking. In addition to the well-placed strikes under her tail, he'd sometimes aim for her pussy, especially enjoying the tinkling sound her piercings made alongside her loud squeals every time she was struck.

Same as with Bunbun, once hints of red showed through her fur he considered her ready. He gave her a quick test to be sure, easily slipping his slick, gloved arm up her ass to his armpit. Unlike with her lop-eared companion, her ears shot straight up at the sudden intrusion; a fact that the cackling dog found endlessly hilarious.

Once he successfully unsheathed his arm from her ass, Dr. Marcus looked back toward Bunbun, who by that point looked completely dazed, at most semi-conscious. Directly under the rabbit's ballgag, the sawhorse's mat was utterly soaked by a growing river of drool. A stream of pre-cum was flowing out of his twitching cage, running down along his enormous balls, forming drop by drop into a small puddle on the floor.

Dr. Marcus sighed happily; moments like those were why he had a special fondness for rabbits. On top of being incredibly suggestible, opening any number of new applications and uses, they commonly had an unusually high sex drive. Keeping them pent up and needy was so easy, and so rewarding. On that note, since Two was good to go, he beckoned over to the fucking machine. Instantly halting it's thrusting, the machine pulled the dildo completely out of the quietly moaning rabbit's rectum, leaving a wide, empty gape. It quickly moved along a track in the ceiling and took position directly behind Two, leaving her to cower in her bonds. As soon as the machine was in place, the piston shot forward, totally burying itself in the female rabbit's rear, beginning its repeated, speedy, mechanical thrusting anew. She let out a loud, shocked groan as she was so completely penetrated, in disbelief despite being forced to watch it happen on the video feed up front. The force of the thrusting made her breasts lazily sway back and forth, almost mesmerizing the gleefully observing dog.

Not wanting Bunbun to feel left out for too long, Dr. Marcus walked up to his side, gently patting his back with his ungloved hand. He stopped for a second, then patted him again, running his fingers through the longish white fur and pressing against the fluffy back.

"Oh... oh my... Were you like this before? Or maybe it's this way because of the treatment?" Placing the side of his face against the rabbit's luxurious coat, he ran his cheek along its length, just about moaning from how soft, warm, and wonderful it felt. "It's like velvet mated with silk... And you're so squishy, but still firm underneath... If this is a side effect of the treatment, then I have plans for you both, yes I do!" Ignoring a weak groan from Bunbun, he used the long fur as hand-holds and climbed up his side. Once up top, he sat on the rabbit's back, straddling his armpits, and draped himself down along the rabbit's spine, burying his muzzle in the soft fur above the short, fluffy tail. "Mmm, this is WONDERFUL!!! Yes, I have plans. For now though, there's one last stage of testing..."

As if signaled by his statement, the door opened, and in walked an absolutely hulking badger, covered in muscle after muscle, barely able to fit under the top of the doorway. Stomping inside, he gradually made his way to the center of the room with a fully erect, dripping cock, big enough to put the fucking machine's dildo to shame, swaying with every heavy step. His balls, though not nearly as big as Bunbun's, were still an impressive sight to behold. If the rabbits could have watched him enter, they probably would have been terrified all over again, though the low, rumbling growl and thunderous footfalls certainly had a similar effect.

"I had a bit of an ulterior motive for testing that specific serum out on you two. Another product we've been trying to develop is an enhancer of sorts. Something to prolong and enhance sex drive. We've had some promising results, but really, at the moment it really just makes monstrous oversexed abominations. One of my workers here volunteered to test it out, and he's in a bit of a bad way at the moment. Since you good fellow are available and capable of helping him work it out of his system, well, Jack, have at 'em!"

Nodding, though barely cognizant of anything beyond an overwhelming need to rut, the badger wrapped his giant hands around Bunbun's waist and pushed his thick tip into the vulnerable hole. Dr. Marcus sat back up, perching his rear on the rabbit's shoulders, like he was attempting to ride him like a horse. He wanted to make sure the badger had enough room to do his thing, but mostly he just wanted a better view of the fleshy ring spreading wider and wider as the pulsing shaft made its way inside. Grunting slightly, the badger's hips soon met Bunbun's cheeks, having fully sheathed his monster of a cock was fully inside the mewling rabbit.

For his part, Bunbun tried to close his eyes, refusing to watch the video feed of his penetration any longer. Even so, that didn't stop the sensations from being somehow transformed into a living cocksleeve for a mutated monster. He could almost swear he tasted the badger's constantly flowing pre-cum in the back of his throat. Before he had a chance to consider much of anything else, the badger sharply pulled out and slammed back in with tremendous force, followed by a furious series of thrusts that threatened to rip the bolted-down sawhorse clear out of the floor.

While Bunbun could only grunt every time the badger slammed the whole way in, slapping against his still sore asscheeks, stretching him well past all reason, Dr. Marcus was loving the now bucking sawhorse. The dog was barely able to hold on, gripping the rabbit's fur just above the badger's hands. Despite his best efforts, after enough powerful thrusts, he was ejected from his ride, landing on the floor with a thud. He was laughing too hard to get up, choosing instead to relax and watch his worker tenderize his test subject.

All too soon, Jack tensed up and emitted a gravelly moan from deep in his throat. Thrusting in one last time, the badger's floodgates opened, totally filling the rabbit with a full-on torrent of cum. Dr. Marcus whistled in amusement as he watched the white-furred belly bulge out on either side of the sawhorse. It looked a bit like a firehose was turned on full blast inside him, which, technically, was exactly what had happened. Regardless, it was truly a sight to behold. By the time the badger ceased humping his rear, Bunbun could have easily passed as pregnant. Though the quivering rabbit remained denied from having his own climax, the cage did nothing to stop the ever-growing puddle of pre-cum on the floor under his crotch.

After Jack pulled his cum-soaked member out of the exhausted rabbit's rear, leaving an even wider gape gushing out his thick seed, he stepped back and looked hungrily at Two, who was still being hammered by the fucking machine. Despite the massive orgasm, the hulking badger's long, thick meat hadn't softened at all, still fully erect and visibly throbbing with his pulse. Jumping to his feet, Dr. Marcus signaled to the machine, which promptly pulled out of her ass, sliding along its track until it returned to its original position behind Bunbun. The piston immediately pushed into his leaking hole, this time remaining completely still, embedded deep in his rear. With the badger now present, it was far more useful as a plug, keeping them from leaking all over the place while he switched between them.

Now that Two was no longer occupied, Jack eagerly stomped over and shoved his slick shaft into her well prepared tailhole with little difficulty. She gave a muffled groan through her gag, in total awe, seeing the video feed of what appeared to be a veiny tree branch spreading her ass open, feeling every inch as it worked its way into her body. She was oddly thankful for the small grace she was afforded when the psychotic dog went against protocol... or whatever the hell that was... and gave her the serum; she didn't want to begin considering what would have happened otherwise. Before she could think much else about it, the badger commenced fucking her just as hard as he did her partner, shaking the sawhorse at its foundation, sending her oversized, pendulous breasts swinging free down below.

"I think Jack can handle things from here," Dr. Marcus chimed in, nonchalantly dusting off his lab coat. Neither the badger nor the rabbits were really in any condition to listen, but he was speaking more for himself than for their benefit. "I really should be going, you two have INSPIRED me, and I don't want to lose that momentum! I have a marvelous idea for you two, yes I do. We'll be seeing each other soon, after the aphrodisiac burns out of his system. Give or take in 8 hours or so." He briefly stopped to watch Jack climax again, bloating the girl's belly out to match her tits, before dismounting and heading back to Bunbun. Sensing the badger's approach, the machine pulled out of Bunbun's ass, unplugging him with a loud pop, swiftly sliding in position behind Two. Almost in unison, both the machine and the badger shoved their massive lengths forward, plugging their respective rabbit's oozing hole as the dog admiringly watched on.

He did regret not getting to see just how much they'd end up inflating, he was far too excited about his new plans to stay any longer. Making his way out the door, he headed for the main workshop to get a team started on building it. He froze in his tracks, suddenly remembering the black latex sheathed around his arm. As excellent as the portable glove technology was, it was incredibly difficult to remove once on. He made a mental note to revisit it at some point, then silently continued onward. It was an annoyance, sure, but so long as he got what he wanted out of those rabbits, he'd live with it.

______________________

The following day, Doctor Marcus sighed in frustration as he scribbled away at a blueprint on his grand, elaborate desk. Muttering under his breath, he reached over and idly scratched at his furless arm. It was beyond annoying, just how incredibly itchy the stupid thing was while his fur grew back in. He spent several moments gnawing on the cap of his pen, then in a quick succession made several small alterations to his latest design, ending by signing at the bottom. With a proud smile, he leaned back in his chair and relaxed, using an unnaturally large pair of breasts as a headrest. The chair, or rather, the lithe, curvy antelope that acted as his chair, gave a weak groan as the little dog reclined against her torso, putting his shoes up on his desk with a sigh.

The antelope was bound to a wheeled, vaguely office-chair-shaped metal frame in a kneeling position, with her lap forming the seat. She was sitting on a small, flat platform, her legs bent at the knees around it with her ankles chained to her thighs to hold her in place. As it was, she could flex her hooves, but that was about it. Both arms were locked up to the elbows inside the armrests, completely encased by solid rubber. A tall posture collar kept her head still, preventing headbutts or the like, while a bit gag muffled any potential noises. A small corset-like device was worn just below her pendulous bosom, and could be adjusted to raise or lower them depending on the height of the user. In addition, a silver chastity belt was locked around her waist, while her ass was filled by a thick, hollow plug that was part of the platform. It hadn't been one of the intended functions in the design, but the chihuahua was fond of using her long horns as a rack to hold his lab coat.

With a tap to a small button on the bottom of the platform, both the frame and the plug buzzed to life, making the antelope groan with frustration as everything began to vibrate. Dr. Marcus hummed happily, slouching back against her as he took a moment to appreciate his home away from home.

The office was a far cry from the spartan, empty room it was when it belonged to Dr. Crane. For a start, several new pieces of furniture had been added, almost entirely made up of damned souls of varying species and gender, bound and objectified same as the antelope. The pack rat of a chihuahua would occasionally hold onto a particularly impressive prototype once it finished development, and by that point had the office very well-furnished.

In his off time he'd developed an additional interest in art, so the walls were also decorated with a number of chained, painted furs, squirming or groaning as much as they were able. He shot a glance toward one of his favorites; a skunk wearing a tight, pink, latex hood, painted with a series of rainbow stripes hanging next to a toucan who, except for the nostrils of his long beak, was fully covered in black latex paint. They may not be able to see him, but he sure loved looking at them.

All too soon, a knock at the door startled him out of his reverie.

"DAMN IT!!! WHAT DO YOU PEOPLE NEED NOW!?!" he screamed, leaping off the still vibrating antelope, leaving her slowly spinning in place. Storming to the front doors, he threw them open with a hateful growl, and was instantly pleased to see Moe and Jeremy had arrived with his nice, new toy. Wordlessly wheeling the large object inside, they positioned it against the wall, attaching a couple of pipes in back to their matching wall connectors, and promptly made their way out.

Dr. Marcus felt elated as he checked out his new bed, which turned out far better than he could have hoped. The bed itself was a simple felt-covered, queen-sized base with a large cabinet, or maybe dresser, instead of the headboard. On top of the base, Two and Bunbun were gagged and shackled on their backs, lying head-to-toe next to each other. In the time since he last saw them bound to their sawhorses, they had been cleaned up and restored to their original appearances, if perhaps slightly thicker and puffier. From what he heard, by the time Jack wore out and reverted to his normal form, the two rabbits looked like tiny-limbed parade floats.

Bunbun's footpaws were pointed toward the cabinet, his over-sized balls resting on top of his pinned-together thighs. The cage around his cock had been replaced with a more hidden one, a simple asterisk-shaped piece of soft rubber attached by several piercings inside the rim of his sheath. Any attempts to get hard would accomplish nothing but painfully stretching out his sheath. A faint glint from his piercing could still be seen past the piece of rubber trapping him inside; the dog was feeling charitable, so he let him keep the extra little adornment.

Two's footpaws were pointed toward the foot of the bed, her massive breasts perfectly aligned with Bunbun's equally sized testicles. Together, they were obviously meant to act as the mattress for the bed, complete with a set of nice, fluffy pillows. Hidden underneath their prostrate forms, a pair of fucking machines had the same kind of gigantic dildo from before buried in their rumps, ready to begin their pistoning, providing something akin to a vibrating if the user so desired. As an extra bit of functionality, these versions of the dildos had hollow pipes inside, leading from the connector in the wall. If the user wanted their bellies to be pumped full of cum, making them squishier and rounder, it was only a button press away.

Not wanting to wait a second more, Dr. Marcus leaped onto the bed, landing squarely on their stomachs, earning a pained grunt from both halves of his new mattress. Given his small stature, they were easily large enough to handle him as he rolled around, caressing their intensely silken fur, and rested his head against Two's soft, squishy tits. The soft, luxurious fur even managed to ease the itchiness of his bare arm. He didn't question it choosing instead to just enjoy himself.

Suffice it to say, that bed was the single most comfortable thing he had ever rested upon. He couldn't imagine ever wanting to get up.

And then came another knock at his door.

"WHAT IS IT NOW!?!" the frustrated dog shouted, sitting upright, putting his full weight on Bunbun's squishy belly. "Did you need a signature or something!?!" The doors promptly opened, revealing not Moe and Jeremy, but his own boss, Milo. Almost immediately, his enraged expression was replaced with one of sheepish contrition.

"This a bad time?" the weasel politely asked as he entered the room.

"Oh. Oh! No, sir, nothing like that, I was just trying out my new bed. New design, hot off the line. Not to boast, but it's... it's quite an achievement."

"I'll bet, it certainly looks interesting," Milo mused, looking the rabbits up and down. "Not sure about having his crotch right next to the 'pillows' though. Seems like that could lead to some nasty surprises during the night. Other than that, I like it."

"Even the best waterbeds aren't immune to leaks, I'll keep that in mind for the next version. At least it IS self-cleaning." Jumping to his feet, Dr. Marcus stomped on a pedal near the bottom of the bed, causing the doors of the tall cabinet in back to slide open with a droning whir. Once the cabinet was completely open, it rotated forward, lowering itself down, totally encasing both the base and the confused rabbits. As it doors closed again, sealing everything inside, the sound of running water could faintly be heard sloshing around from within.

Giving an impressed nod that filled the chihuahua with professional pride, Milo took the opportunity to look around and see for just how much the office had changed since his last visit. "Wow," he mumbled, "You really did a number on this place, huh?"

"Hm? Oh, yes, I suppose so. I have a hard time parting with my greatest successes and I've built up a decent collection... That's... alright, isn't it?" the little dog asked, worriedly wringing his hands.

"That's fine, there's plenty..." Milo replied, trailing off as he noticed a large pair of glinting gold rings against the wall, hanging vertically by chains descending from the ceiling. They were somewhat obscured behind a large plastic divider, but the small mystery, along with the few parts he could see, easily got his attention. "What's this you have hidden away here?" he asked, wandering over to get a better look.

"Oh!" the little dog shouted, sprinting over to join his curious boss. "They're just something I like to tinker with in my off time... You could say I have a bit of an artistic streak, and I had a couple of new ideas I wanted try implementing," he awkwardly explained, faintly blushing.

An impressed whistle escaped Milo's lips as he got his first good look at the nervous chihuahua's secret project. Indeed, the two sturdy metal rings appeared to be frames for elaborate art projects, each housing a pair of squirming prisoners bound in the center.

The first ring had a red fox and mouse suspended muzzle to muzzle, chained by their wrists and ankles to the rim, tautly stretching their splayed limbs outward. They shared a single large red ball-gag between them, forcing their heads to tilt to the sides, meshing the open mouths of their muzzles together. Their tailholes, as would be expected, had thick plugs stuffed inside them, though the most notable thing about the entire setup was the single chastity cage they shared. The cage was little more than a short hollow metal tube, with either opening fitted over the fox's and mouses sheaths, and a ring locked around their scrotums to hold them together. Any attempt one made at getting hard would only turn into a frustrating joust with no winner, especially if the vibrating plugs had their way.

The second ring was roughly similar to the first, though this one had two horses suspended back-to-back, one with tan and white spotted fur, the other with a solid dark-brown coat. They each wore a bridle with a bit gag stuffed in their mouths, making them drool as they uselessly attempted to push them out. A small padlock connected the backs of their bridles, binding their heads together, while a thick, knotted, double-sided plug did the same for their rears. Instead of being trapped inside standard cages, each of the long equine shafts had been fitted with snug latex sleeves, wrapped around their lengths from the root to a thin gold ring just behind the flare at the tip. The latex-encased slabs of horse meat were bent between their owner's legs, forcing their swollen balls to either side as it pressed uncomfortably against their nutsacks. A series of thin chains connected the flare rings, holding the dual shafts tip to tip, just below where their asses met, with a long sounding rod inserted, one end in each piss slit. Like the fox and mouse, any attempt either horse made to grow erect was doomed to descend into a painful tug of war, leaving them both needy and totally denied any actual pleasure.

To say the least, Milo was completely floored by Dr. Marcus's work; the new head of R&D certainly had a creative, if slightly devious mind, as well as a strong eye for detail. He knew he was the perfect choice to replace Dr. Crane. There was something itching at the back of his mind as he looked head-on at the rings. Something he almost recognized, how both bodies were aligned, one hidden behind the other, but their limbs weren't. They were all askew, giving the impression of a single body with two extra arms and two extra legs. Milo squinted, trying in vain to remember why it seemed so familiar. Suddenly, he looked over at the curious dog, snapped his fingers, and shouted, "Vitruvian Man!"

Clapping his hands together, Dr. Marcus shouted, "Got it in one! Excellent work, sir! I saw that old sketch and couldn't help trying to bring it to life. So, what do you think? Be honest!"

"Excellent. Not much more to say than that. Maybe the best I've ever seen. There's no, um, risk of damage with the fox and mouse is there?"

"I did consider that. Like how the back-to-back model requires hung individuals, for the face-to-face version I made sure to pick subjects who are... less equipped, shall we say. With their lengths they'll mostly be dealing with quite a bit of ball stretching alongside the constrictive width."

"Purely excellent work. The only suggestion I could possibly make is to replace the bit gags on the horses with ring gags, then flip the whole thing upside-down, putting their mouths at crotch level. Interactive art is the best kind, right?"

The little dog's face lit up at the recommendation, proudly beaming at the approval of his work. "Thank you sir! That means a LOT to me! Thank you!" he shouted, giving Milo an unexpected hug, accidentally tackling him against the wall in the process. He meekly laughed, clumsily climbing off the surprised weasel, and politely helping him to straighten his robes. "Sorry about that... Guess I got a bit worked up."

"It's alright, don't worry. No harm having pride in a job well done... which... on that note, brings me to why I came down here. I'm having a bit of a... a problem that I need to talk through with someone. Do you mind?"

"Of course not, sir, I'm happy to help! What's the problem?"

"We're, um, free to talk, right?" Milo asked, tapping his ear.

"Yes, they're all plugged. In a few ways. They can't hear us."

"Okay then. I've been reading through the old contract that Chas gave me, the one agreed upon by the sins ages ago, trying to find some loophole we can use against Avarice. I haven't found anything useful there yet, but I stumbled on something strange. Basically, the sentence of anyone in Hell is reset when a new caretaker is chosen, which means by some trickery of paperwork, there's a legion of unfairly eternally damned souls down here. I feel like I need to bring this up to Chas because it seems... just... just wrong, and-"

"I have to cut you off there, sir," Dr. Marcus nervously, though firmly interrupted the startled weasel. "Respectfully, I want no part of this, and I decline to participate."

Furrowing his brow in confusion, Milo could only stammer, "I'm sorry? What? You decline?"

"I thought you wanted help with a design or ideas or something! Not some MORAL quandary with the GOAT of all things! I wish you the best of luck dealing with your problem, but I won't help you."

The happiness faded from Milo's face, rapidly changing to something more like a mix of annoyance and offended rage. "I'm afraid I don't understand what you mean by 'Won't help me.' Please, elaborate."

"I believe I said everything I need to on the matter."

"You know I can force you to do anything I want, right?"

"Yes, and you'd have to. But I don't think you will."

"Really," Milo grimly uttered, crossing his arms, glaring down at the short dog.

"Look, try to see things from my perspective. I want what you want, I'm a piece of you after all. You're asking me to get between you and the being that gives you your power. The last one of us to do that, even just tangentially, got exploded before our very eyes. Frankly, I'm terrified of that happening to me. Existing really fills up the better part of my schedule, and I'm not going to put that at risk without being forced to. The same is probably true of everyone else, for that matter. After what happened, no one's really champing at the bit to be the next to face the goat's wrath." Gesturing toward the nearest horse's gagged mouth, he added, "Present company excluded. We all fear you, sure, but we fear the goat WAY more." Crossing his arms in an obviously false attempt at showing bravery, he shakily added, "Do what you will."

"You... you're right," Milo said, sighing heavily. "This is my cross to bear, I shouldn't have tried to pawn it off on someone else. After that previous incident, I guess I'm kind of nervous about bringing something like this up while being empty-handed so far as handling Avarice... For now... I'll just need to talk to Chas and hope for the best. Thanks for listening anyway, it did help a little, just having a sounding board."

"That's something, at least. Don't worry about it too much. The goat's nothing if not reasonable, just be respectful and voice your concern, it'll be alright."

"Good advice. I'll get out of your hair for now, it's past time Chas and I had a chat and figured something out. Thanks again," Milo said, briskly striding toward the front doors. He briefly stopped and added, "And I expect to see those Vitruvian men in the throne room soon."

"Will do, sir!"

"Take care, and keep up the great work," the weasel said, disappearing through the doorway.

"Be safe," Dr. Marcus whispered back, showing more than a little worry. With his boss gone, his maniacal grin promptly returned, creeping across his muzzle as he looked over at his still vibrating antelope chair. He took off in a sprint, leaping onto the empty lap, knocking the wind right out of her and sending them both spinning right up to his desk. Flipping through his files, his pulled the template for his Vitruvian sculptures and hastily scribbled the notes Milo had given him. As he wrote, he remembered a new addition he had made to his desk, or rather, under his desk. Kicking off his shoes he placed his footpaws on the ring-gagged muzzle of a lynx, who was encased up to his shoulders in the base of the desk.

The instant the bare footpaws made contact with the gagged feline's face, a hidden chastity cage and butt plug began sending shocks to his sensitive parts, not ceasing until he gave the musky appendages a thorough tongue bath, lavishing the dog's toes and pads with slobbery licks from his long, rough tongue.

Stifling a crazed giggle, Dr. Marcus soon regained his composure and resumed writing out his notes. Confrontation aside, that little exchange with Milo may have been the highlight of his short career, if not the highlight of his life. Either way, with that boost to his confidence, he couldn't wait to see what else he could do.

Grabbing a fresh piece of graph paper, he placed it flat on the desk, staring at it as he enjoyed the feeling of the vibrating antelope and the rough lynx tongue lapping at his soles. An evil grin appeared on his muzzle, and he started to furiously draw out something new. Something wonderful. Something amazing. Yes, indeed, he had plans.
