Follow the Rules

[shrinking, animal TF (rats), bodybuilders]

Nick’s nipples got hard the instant the handcuffs clicked around the massive hunk’s wrists. “Fuck,” he said as he chose a pair of silk boxers from the duffel bag brought by the enormous man–Clay was his name, wasn’t it?--and folding them into a strip before tying them around Clay’s eyes. The big man struggled at his cuffs with a smile, flexing his massive arms. Nick worried for a moment that the lug would be able to yank free of his restraints. Of course, he didn’t truly want to–that was the point–so Nick’s worry was in vain.

After oiling up his hands, Nick started massaging the big brute’s piles of pec muscles. Nick wasn’t a small man himself–5’10” tall, 220 roid-inflated pounds that filled out his shirts and told everyone who saw him, “Yeah, this guy lifts…”--but he appreciated how absolutely scrawny he felt next to Clay’s huge quads (same width around as Nick’s waist!), the impressive shelf his protruding lat muscles made, and his deep muscular armpits.

“Fuck… this really is kinky,” Clay said as his cock twitched. Nick grinned; Clay’s dick wasn’t small by any means, probably measuring up to about six inches and decently thick, but it looked stubby and unimpressive attached to the rest of his 6’4” 280 pound body. This was a king-sized man with an average cock. Of course, that’s where the massive bulge in Nick’s jockstrap came in handy.

“You like not knowing where I’m gonna go next?” Nick said, removing his hands, then softly kissing up Clay’s rippling abdomen before licking in his armpit. Clay moaned, twitched from reflex, then allowed himself to submit to the sensations as Nick buried his face in the deep crevice.

Nick had planned for the foreplay to go on longer, but his 9-inch rod kept smacking Clay’s brick-solid torso every time he turned. The impact made Nick want to yelp, but more than that it made him want to get Clay’s absurdly large legs up on his shoulder to start pounding the massive but Nick had gotten a look at earlier, when Clay had walked into his house.

“Your husband doesn’t care?” Clay had asked.

“I’m allowed to play around,” Nick had said with a wink.

“That a big cock you got in there?” Clay had asked, gently jostling the front of Nick’s shorts seconds after they’d met.

“Lemme just say it’s a perfect fit for an ass this size.” Nick gave the wide, bulging glutes a swat, feeling like he’d slapped granite.

“Holy shit,” Nick said as he finally entered Clay’s ass.

“Oh fuck–oh FUCCCK!” Clay moaned, his body writhing. Luckily the restraints held him in place. Blindfolded, the big stud looked around the room, as if searching for the man burying himself deep in Clay’s ass. “Oh… oh god, oh god oh GOD…”

Nothing better than a loud roidpig, Nick thought as he watched Clay’s flopping little dick spurting wildly around his tan, hairless musclebod.

“Fuck… fuck… FUCK…”

Nick was biting his lip, knees on the bed, too lost in the ecstasy of Clay’s incredible hole to worry about expressing himself vocally. Then it happened–a chill went through his body, a tingle like electricity, and suddenly Clay’s hole didn’t feel quite so tight anymore.

The huge thighs seemed to double in weight as Nick looked around, shocked to find that Clay–and everything around him, in fact–had doubled in size. Still focused on his hip thrusting rhythm, he continued to fuck the giant (to him) man, not entirely aware that he’d shrunk down to four fee tall. Clay’s volume diminished in line with the diminished presence in his ass.

“Oh fuck, what did you… c’mon, big guy, keep fucking! Fuck me harder!”

Nick, still humping, wasn’t sure what to say. He wasn’t even sure if he should stop. He just kept cramming the sensuous brute in front of him before another tingle spread over him. He cried out as Clay’s legs now knocked him over.

Nick was only about two feet tall now, barely able to make a dent in the man before him, and now it was time to say anything.

“Fuck, fuck what… what happened?” Clay said, writhing, desperate for the feeling of being stuffed full to return.

Nick wasn’t sure what to say. Another tingle–and he found himself staring into the crack between Clay’s cheeks, now small enough to crawl between them if he’d wanted to. He shouted for help, but his shrimpy little voice wasn’t loud enough to be heard over Clay’s grunts and heavy breathing.

“Fuck, babe… what happened? Why’d you stop?” Clay asked. Then he felt the chill,, the tingle, and his hands slipped right out of the handcuffs as he stumped down to three feet tall. The blindfold fell down around his shoulders. “What the hell?” he said in a higher pitched voice. A few more pulses and he found himself struggling through the bed’s sweat-and-jizz-soaked comforters, only a fraction of the size he’d been before.

The bedroom door creaked as Nick’s husband, Malcolm, watched the two buff men suddenly shrinking down to tiny versions of their muscular selves. He chuckled as he watched the now-four inch tall men scurry around HIS bed in a panic. They got lost in the bedsheets very easily, and he watched the lumps moving slowly around before snatching the one he knew was Nick’s side-piece between his palms.

“Oh, nice!” Malcolm said, opening his hands like he was revealing a butterfly. Clay was inside, beating frantically against the giant fingers around him (just a tickle to Malcolm). All resistance died out of the little guy when Malcolm’s goateed face appeared to him. He cried out, a laughable chirp from an impressively muscular (though pathetically tiny) little body. “Oh, this guy sure is well shaped. I appreciate your taste in men, Nick!” He plopped Clay on the bureau. The little muscleman scurried toward the end, but Malcolm’s hand kept him from tumbling off the edge.

He poked the roided out little man with a big finger, knocking him on his muscled butt. “I’d stay put if I were you. That’s a LONG fall off the edge.”

He turned back to find Nick climbing down the duvet cover. He laughed as he snatched up his beautiful husband by the ankle, dangling him upside-down as he held him up to the light. “I do so LOVE seeing men at their tiniest,” Malcolm said, ignoring Nick’s pipsqueaky cries, so high-pitched his words were barely discernible. “I should get out my jeweler’s eye and study every delicious little line on those abs, and the beautiful detail of that gorgeous cock, knowing that you’re smaller than even MY dick, now.”

He turned to address Clay, who was eyeing up a bottle of lube he had set on the bureau earlier. It was twice his height now. “You! Little man. Escort, trick, whatever you are,” Malcolm said. Clay spun around, shrieking again as the giant man approached him. “Oh, settle down. I don’t intend to punish you too much. It’s this damned husband of mine who’s to blame for this. Now…”

Malcolm gently set Nick on the floor, then pressed his bare foot down over him. Nick was trapped in the arch, shrieking as he felt the growing pressure above him increasing.

“So, little trick. This next part has EVERYTHING to do with you,” Malcolm said, sliding his thumb and forefinger along his facial hair as he licked his lips. His pants were tented by his rock hard cock at that moment. “You say the word–or give me the thumbs up, because I probably can’t hear your tiny little vocal cords now–and I’ll press my foot down, making my husband no more than a stain on the carpet, BUT I’ll return you to your normal size and allow you to walk out the front door–albeit with a sizable ‘hush’ fee. The alternative is to choose to participate in whatever punishment I choose for Nick–it won’t be splattery, but it will impress upon you JUST how angry I am. Your choice?”

Clay shook his head, staring around the room as if he would find a way to escape. “You have ten seconds, little one,” Malcolm said, increasing the pressure of his foot. Clay looked horrified, his chest heaving, no doubt filled with more terror than his weights-and-roids-filled life had ever presented him with.

“Three seconds!” Malcolm said, but Clay threw up two “thumbs-down’ signs. Malcolm smiled. He raised his foot and snatched up Nick, clasping his fist around him such that only his head popped out. “Good news, cheating whore! You don’t end up scrubbed out by a sponge tomorrow morning.” He quickly grabbed Clay the same way, holding his two fists together so the two “lovers” could see each other now. “Want to kiss? I know neither of you got to finish.” They both looked scared, but stayed silent.

Malcolm entered their walk-in closet and kicked the lid off a box. Inside was a small cage, complete with a hamster wheel and an inverted water bottle. Without concern to their well-being, he dropped both men in the cage, then hoisted it up and set it on the bureau next to the lube.

“Now,” he said, sliding a key into a locked drawer in his nightstand and pulling out an atomizer with a rubber bulb. “Nick, since you think your boy here is JUST so delightful to look at, I want to see if you still like him after a few alterations.” He snickered as he noticed the two muscular four-inch-tall men holding each other as they stared up at their captor. “Aw, so cute,” he said, knocking them apart with a single finger. Clay caught the blast from the atomizer on his chest and face. He winced, sliding backwards as he tried to wipe off the glittery liquid.

“What did you do to him?” Nick asked. Clay’s chest was heaving, his hands quivering. Both tiny men were waiting for something to happen; clearly, if Malcolm could make them this tiny, he had other tricks up his sleeve.

“Oooooooohhhh WOW,” Clay said as he flipped over, rubbing the spot above his twitching glutes. “Fuck, that… that STINGS… ouch.” Just above his quivering muscle butt, a knot had sprouted. His hands slapped to it as he hopped from foot to foot.

Suddenly, his solid jawline looked rounder. His ears had grown twice as large, making his handsome face look goofy. Buck teeth suddenly protruded from his lips. He let out a yelped and lurched forward as a veiny tail burst out from his backside, twitching back and forth. It slapped him in his face; he slapped it away.

“What did you do to him?” Nick asked.

“Well, he’s a fucking rodent! A tiny pest,” Malcolm said after a hearty laugh at the heavyweight bodybuilder’s dismay, his flawless, god-like shape breaking down into something more laughable every second. “So now he looks the part! I’m going to let him loose in the house, let him hide in the walls and subsist on cheese and scraps. Better hope you don’t get caught in one of our traps, little mouse!”

Clay’s face pushed into a snout as fur sprouted over his smooth body. He exuded a stink, a new feature as he transformed. Even Malcolm, whose head was high above the little half-man/half-vermin, could smell it.

“Now, as for you,” Malcolm said, turning the atomizer on Nick (who recoiled from the man he’d been desperate to fuck just an hour before). The puff of liquid caught Nick by surprise; he shrieked as it coated him. Clay’s transformation had slowed; he had a fully-mouse head, claws and a tail, but otherwise he maintained his human shape (albeit fur-covered). Nick screamed as he realized this would be his own fate as well.

“Oh, I’ve got something different’ planned for you,” Malcolm said. He held Nick down with a single finger and hit him with another spray, this time on his lower half. “You’re a little maggot, so that’s exactly what you’re going to become. You’ll be wriggling around, blind and helpless, until you finally make the metamorphosis into a fly. And once you’ve spent enough time dining on shit and thinking about what you’ve done, only THEN will I turn you back. That is, if your lover over there doesn’t snack on you when you’re a disgusting, wriggling little worm!”

Nick collapsed, his legs going weak with despair. Meanwhile, Clay, now a human/rat hybrid, sauntered over to the large wheel. Something compelled him to climb into it and start running; clearly, his instincts to exercise were asserting themselves even in his new form.

Nick screamed again when he felt a pain in his rear. He leapt up again, surprised when he, too, had a rat tail.

“Ah, I was just joking,” Malcolm said. “You’ll be a rat too. But truly, doesn’t it seem like a less harsh fate than becoming a MAGGOT? I think fibbing to you was an act of kindness.”

Hair sprouted over Nick and his hunky cover model face morphed into that of a filthy mouse. He let out one last shriek (no longer able to form words after his snout had shaped) as his cock suddenly retreated.

“Ah, one last thing,” Malcolm said, chuckling. “YOU will be a GIRL mouse. I think your days of being on top are over. Let’s give your friend over here a turn learning what it’s like to fuck YOU instead.”

A month later, Malcolm placed the Clay-mouse on the floor and sprayed it with a different formula. He scurried around a bit, then vomited before his body doubled in size. By the time he was as big as a house cat, his tail had diminished, his facial features softening. When he was about three feet tall, his fur had mostly vanished. He let out a long groan as his limbs lengthened, his claws reshaping into fingers, his cock returning to its human state.

When it was over, Malcolm had a nude bodybuilder lying at his feet. He slapped the gargantuan man on his muscled behind, then clapped his face. “Up and at them, now,” he said. “Your stay in my home is LONG over.”

Clay examined his hands as he stood, patting down his muscles, clearly relieved to have them again. Tracing the smooth lines of his face, his posture finally relaxed. Malcolm slapped him again to snap him out of it.

“A-am I… am I totally a person again?” Clay said, rising. “Whoa, I’m… BIGGER than I was before,” he said, shocked at a substantially larger chest that blocked even more of his view of the floor. His legs were much thicker, his arms propped up by thicker lats.

“Well, you ran on that damned wheel nearly the whole time,” Malcolm said with a shrug. He tossed some gym clothes at Clay’s feet. “It translated to much more muscle when you turned back.” He smirked as he watched Clay struggling to squeeze into the clothes; Malcolm hadn’t shopped large enough, clearly. The shorts split down the ass on Clay’s first step, the sleeves bursting the moment he moved his arms.

“My assistant downstairs has some documentation for you to sign,” Malcolm said, waving his hand dismissively. “You’re forbidden to speak of anything that’s happened, and if I ever see you around Nick again, I’ll make you a rat–a FULL rat–permanently. Otherwise, there’s a substantial sum of money for you to put your life together after you’ve been missing a month. I hope you enjoyed your stay.”

Despite being twice Malcolm’s size, the swollen muscleman hurried out the door, his now-metaphorical tail between his legs. With him gone, Malcolm returned to the cage, sighing as he saw Nick, even fatter than he’d been the day before.

“Aw, don’t look at me like that!” he said as the little grey-furred rat stared up at him, panting. “You’re lucky I let you have a companion in there at all.”

Nick rubbed his swollen belly, careful not to touch his protruding, sensitive nipples. He struggled to his feet, waddled to the water bottle, and had himself a substantial drink before sinking back to the floor and rubbing his huge belly again.

“I can’t turn you back yet,” Malcolm said. “Not with that litter of rats inside you! FIRST you give birth, then I can make you human again. We’ll be bringing your little offspring to the pet store right away. The last thing we need is your wretched little offspring stinking up MY house!”

Nick let out a forlorn sigh as Malcolm turned away. “Honestly, Nick, if you weren’t so damned stubborn, I wouldn’t have to go through such rigors to make sure you learned your lesson. Imagine if you’d just followed the rules?”
