Primal Gym

added by JLTF 4 months ago A BM S

"I need to get a workout in the gym in and then we can hang out. How about you go up to my room and rest," Steven offered. "You're looking really tired."

"Yeah?" Jack said. He leaned more of his weight onto Steven's body, gently running his hands up and down against the soft yellow fur. "I am feeling a bit tired... Maybe I'll go to my room."

"No. My room," Steven said sternly. He saw Jack tighten. Then softened his approach. "I mean. My room. Then when I'm done with the gym, I don't have to come and find you. How's that sound?" He added a few soft jabs of his elbow into Jack's side.

A bright smile filled Jack's face as he practically hopped towards Steven's room. "Yeah! That sounds great!"

"Perfect," Steven smiled to himself. He felt around in his pockets feeling the three eggs still there. Then headed for the gym.

-=-=-=-=-=-=-=-=-
The gym tended to be fairly empty during the day as most of the other college students had class and they wouldn't want to be smelly if they could help it. However, Steven was happy to find three guys from the football team changing into their sweats. "Think fast," he said. Instantly the three prepared themselves as Steven tossed them each an egg. Each one of them caught it without any trouble.

An almost evil smile crossed Steven's face as he watched the three guys. He'd never seen this happen to anyone else. Their eyes went wide, mouth went wider, and their hands went to push the eggs up their backsides. Each one moved at different speeds as they were clearly trying to fight it more. Yet, that was a clearly losing game. The eggs continued to draw closer to their destination.

Greg was the first to lose. The large lineman pushed the egg up inside himself causing his face to twist and turn. It started with a grimace but quickly turned to delight as his finger continued to swirl around his asshole. His mouth hung open with his eyes still at a glaze. Sharp canines showed through as his lower jaw pushed a bit more forward. It was the same with his brow as it was now shrouding his eyes Nostrils flared wide. His nose bent upwards and then forwards, giving him a bit more of a primitive facial structure.

The natural brown hair Greg always had, turned pitch black. It started with his eyebrows and then quickly moved to the top of his head. Hair grew sprouted out around his chin making his rounded face at least look a bit more square. The hair continued down his neck, growing so thick it would be better described as fur. Anywhere the fur sprouted, Greg's body would grow in size. The already large man only grew bigger.

First it started with his neck. Then quickly went to his chest. The two pecs bloated outwards as muscle and fat added onto his frame. He'd always been a bit on the heftier side. If Greg was to be a good lineman he needed a bit of extra weight to properly take a tackle. The growth only amplified his natural frame, making him bigger, but also far sturdier as the bulky gut turned into a leaner more surly stomach. His biceps and triceps doubled in size while his forearms more than tripled. The already massive hands at the end of his arms somehow grew even bigger. The color turned a bit more ashen and gray as his hands pulsed with new size.

The fur continued down his legs, making his legs and ass far more refined than they had been. However, it was his feet that were the most interesting as the toes started to shift. As his feet grew larger, each of his toes seemed to grow long. They clenched at the ground as new joints formed into almost like fingers rather than toes. Even his big toe pulled back making his foot more into the palm of a hand rather than a human foot.

Greg's bones creaked and cracked as they grew longer and thicker to hold his new growing frame. At 6'6" he was always one of the biggest guys in the locker room, but with the 6 inches added to his height, he'd be looking down on everyone. His body fell forward and giant hands gripped the bench between the lockers.

Seeing Greg's giant gorilla ass in front of Henry, he was the second to lose out. The fear, discomfort and arousal all swirled around in his brain as he tried desperately to keep the egg from entering into his asshole. But the second he saw Greg's fingers continue to play with hole, Henry gave into the arousal. His three inch cock throbbed with delight as his body moved behind Greg's. The only problem was that there was so much ass on the gorilla that his dick couldn't reach the hole. It only pressed its tip against it.

That didn't last long. Blood pumped into the small member, quickly growing it. An inch added on to Henry's cock and plunged partially into Greg. The big gorilla let out a bit of a grunt as another inch grew into him. A cocky smile filled Henry's face as he felt his dick digging deeper inside the bigger man. With each thrust another inch was added onto his cock and he could feel the small hole tighten around it as it grew wider.

"Aww... Fuck man..." Greg panted as more and more cock split open his ass. "When'd you get so fucking hung?"

"You complaining?" Henry taunted. Another inch grew on his dick causing the gorilla's eyes to go wide. Greg's tongue lolled out of his slacked jaw as Henry fucked him.

Neither one noticed as Henry's muscles grew more defined. The rather toned running back always made sure to have a fairly low fat percentage to show off to the ladies. Though, right now his lean muscles were bulking up. Not gaining any more fat, but growing far larger than they had been. A natural country roughness added to his body as his muscles developed.

Henry let out a neigh as his big balls swung back and hit Greg's. They'd nearly doubled in size and were churning with cum. Henry's hands gripped the sides of Greg's body. His fingers dug deep into the other man. The nails on his fingers turned black and hardened into parts of hooves as the space between his four fingers merged into two. His feet were different as the hooves covered his entire feet, switching his stance ever so slightly.

Coarse chestnut fur sprouted over his defined muscles covering every inch of the football player's body. He let out another neigh, shaking his head as his jaw pushed further out in front of him. A long horse's snout formed as his nostrils flared and widened. His ears grew to points and flicked with excitement as the short hair on his head grew into a luscious mane that ran down the back of his neck.

Teddy watched in horror and awe as his friends turned into wild animals. However, his throbbing cock betrayed him as he witnessed his already masculine friends grow into absolute beasts. It begged for his attention with each addition that Greg ad Henry developed. Little by little the egg pushed further inside. His anus opened up accepting the round object.

"Oh fuck yeah!" Teddy grinned as he stood up. A tail shot down his backside and began wagging as dark brown fur covered it.

"Dude," Henry scolded. "What are you waiting for?"

Teddy wasn't really sure as he saw Greg's wide open mouth and approached it. He positioned his cock directly in front of it and Greg accepted the rod. His tongue swirled around the tip. "God damn..." Teddy cursed.

Greg's arm swooped around the swell of his back and pulled him forward. Henry leaned in for a kiss of the still mostly human. However, as he did those human features of his face shifted into something far more lupine. Teddy's nose turned black and a distinctive snout grew out where one had not been before. His ears grew to points and then shifted to the top of his head forming large triangles. Thick brown, black and grey fur sprouted around his face and ran down the rest of his body, coating his muscles.

Those average sized jock muscles quickly developed into something far more fierce. Thick veins bulged through his skin, pumping each one full of power and strength. Heavy pecs pushed far out in front of him. Massively round shoulders with his trimmed waist gave him an unbelievably intimidating frame. His biceps nearly doubled in size, looking far more for showing off than actual sport. With all the weight in his upper body, his lower had to grow to hold it up.

Teddy's tail wagged fast as he felt the strength adding onto him. Though it could have just been Henry's tongue in his mouth or Greg's tongue on his cock. Either way, these guys who would have made fun of other guys for merely standing too close to each other were currently cock deep in one another. Each one happily enjoying the company of the other men.

Steven's maw flashed his sharp teeth as a devilish smile formed on it. He felt thick claws burst out of his fingertips while his hands grew even larger than they had been. Tiny paw pads developed at the tips of each of his fingers and a larger one around his palm. He felt his feet shift and change more into paws. The same claws and pads on his fingers grew onto his feet and toes. His body raised a few more inches as his heels rose off the ground.

"Perfect..." a deep primal growl rolled out of his mouth. He pawed at his cock, watching Teddy's exposed anus. The wolf's tail wagged excitedly at the sexual experience he was currently having, and Steven knew that he could easily make it better. Or maybe he could fuck a submissive gorilla, or a country horse, or a controlling bear, or a excited fox. Though, he had to wait. This thick cock was meant for Jack. A rumble of frustration hung in his throat as he maintained his distance and let the other jocks fuck. 'In due time...' he prided himself on the will power. The only thing holding him down was thinking about that rabbit's ass. 'In due time...'
