The Spandex Biker

Chapter 3

Matthew stood under the broad, brass shower head as he let the cool water rain over his body and run down to the fake marble tiles below his feet. It was nice to just stand there after such a long run, letting himself cool off completely as he took deep breaths. He could feel the water running along his crotch and down his half-hard member, it channeled down his back, running along the cleft of his round, muscular ass. Every part of his body was soon drenched, goosebumps prickling up along his back.

He reached his hand out and turned up the hot water, letting the shower get warm, just above his body temperature. He grabbed the shower ball beside him, pouring liquid soap with a spicy, musky scent over it before lathering up. His mind wandered to that man with the flat tire, to the image of his rump stretching the spandex shorts so perfectly. He knew he should not have slapped that fine ass, but he could not resist. The way he saw it, he had a one in ten chance something would come out of it. He was more than willing to take that bet.

Even though he had lost, he was glad to have felt the firmest rear he had seen in a long time. Either that, or he had just gone without sex for far too long. Indeed, when he rubbed the ball over his crotch he felt just how hard he was becoming. His uncut shaft stood proudly in front of him at just over seven inches, his sac tight up against him underneath. He let the bath ball fall to the tiles and wrapped his hand around his shaft, a soft grunt escaping his lips as he pulled back the foreskin to free the swollen, purple head underneath.

Matthew was surprised at just how horny he was, his toes curling into the tile as he rested a hand on the wall to brace himself. His other hand glided up and down his shaft, lubed by soap that quickly washed away leaving wet flesh to flesh. He stepped just out of the shower and rested his forehead to the wall, closing his eyes as he masturbated. He imagined that ass again, rethinking the scene in his mind, wishing it had gone a completely different way.

"Yeah, it's called Galvin, you can only find it in a few places now though." Matthew said as he watched Shane put his bike back together. Getting the chain around was another difficult part, one he knew all too well. His eyes were drawn down though as the younger man bent over to loop the chain back around the gears. The guy had a cute ass, especially in that blue spandex. He could not help himself and gave Shane a slap on the rump. "You're all good to go?" He asked with a smile.

Shane immediately stood up and turned to Matthew, a brow raised. "Dude, what are you doing?" He asked and Matthew backed up a step. "That's not the way you slap a guy's ass, you can do better!" The younger man said as he turned around again, peeling his shorts down in the back to reveal a tight, hairless, well-tanned rump. He turned his head back with a look that begged Matthew to slap it again, and he did.

It was hard enough he left a red print of his hand in the soft flesh, causing Shane to moan as he grabbed his bike. Matthew slapped it again, a little harder this time. "Bad boy, breaking your bike like that. You know how much that thing costs?" He said in his best gruff voice and Shane just whimpered, wiggling his ass for another slap.

After the fourth, Shane cried out and looked back at Matthew with a lustful need in his eyes. "Fuck me, pound my ass hard to teach me a lesson." Matthew just grinned wide and pulled down his pants, his rock hard cock already lubed with precum as he slammed it into that perfect, rounded ass. It was so hot inside of it, the tightest hole he had ever sank his dick into, and he did so over and over. He pounded that ass while Shane begged for more, pounded it until the young man could not walk straight.

Matthew exhaled with a shaky breath, imagining that boy cumming all over his bike without touching himself once. He could almost feel his sac slapping against that hairless ass, his fist clamped around his cock until his knuckles turned white. He was getting close, oh so close. He stood up, putting his back to the wall as he fapped wildly. He even let out another moan as he got close, but then he stopped.

He thought he had heard a whimper coming from outside. It sounded like Stag's voice. It was probably nothing, that dog could whine at the littlest of things sometimes. He had already lost his high though, and went back to stroking his cock. It did not take long to regain it, his hand slipping down to cup his sac and squeeze at the orbs as he stroked himself quicker. Preseed rolled from the slit now, causing his hand to glide over his skin as he jacked, his body quivering just a bit. He was there again, the edge of climax, just a few more strokes and...

He heard the whimper again, but this time it sounded like it came from within the house. He was sure he let Stag out onto the porch and the dog never did figure out how to open the door. Still, his curiosity was piqued and he stepped out of the shower, still not having finished himself off, and patted himself with a towel so he would not drip all over the house.

He walked out into the hallway, cock bouncing at each step reminding him just how painfully horny he still was. He came out to the living room and kitchen, looking around for the noise, then looking outside for his dog. Stag was no longer on the porch, but the screen door was still closed. It was quite odd. He walked over to the sliding door and opened it enough to peek his head out.

"Stag?" He called, looking both directions down the house. Maybe he had gotten out, the dog was big enough to take care of himself, but it still worried Matthew. He would have to grab some clothes if he was going to go out looking though, so he closed the door and turned around.

Or at least, he tried to turn around. His feet were stuck to the floor like they were super glued. When he looked down, he saw he was standing in a puddle of black. Whatever the hell the stuff was, it wasn't letting me pick his feet up. He bent down and grabbed an ran his hand over the liquid, but it felt quite solid to the touch. He grabbed at an ankle with both hands and pulled as hard as he could without losing his balance. His foot still did not budge.

Matthew's nose tingled as he caught whiff of something odd. The scent was salty, heady yet had a familiar undertone to it. It smelled a little of polished leather. He took a deeper breath, his member pulsing at scent. It made a shiver run from between his shoulders down to the base of his spine. The scent was intoxicating, calming and so - Matthew could not quite place what else, only that he enjoyed it.

He did not notice the black substance creeping up his ankles and locking his hands as the scent distracted him. Only when he tried to stand up did he notice he was firmly stuck. His heart skipped a beat and he pulled as best he could, bent over at the waist with his member bouncing under him. Embarrassingly, it was dripping preseed which splattered about as he struggled.

Shane watched with a smile from the corner of the room as the man became trapped in what used to be his dog. He leaned against the wall, legs crossed at the ankles as his tail swayed lazily behind him. His barbed member stood proudly in front of him, a puddle of his potent pre now slicking the floor in front of him. It filled the room with his scent, slowly but surely magnifying the libido of his next victim. He watched that ass as Matthew struggled, licking his lips and giving his member a stroke as he lifted himself off the wall and padded silently towards the man.

"Aw, Stag only wants to play." He said when he got close enough and Matthew swung his head around. Shane only smiled when he saw the struggle on the man's face to come to terms with what he was seeing and soon lifted a handpaw, wiggling his fingers in a wave as his tail swished behind him.

"Wh-what?" Matthew was dumb-struck. He was staring back at some kind of walking, talking animal made of spandex and rubber. What was more, it has quite a large, erect shaft in its paw and an ominous smile. He gulped, not sure what to ask before he realized what the feline had said. His dog's name. The creature motioned with its eyes down to the floor and Mathew looked down, the familiar head of his beloved dog pushing out of the puddle on the floor.

"Stag?" Matthew gasped and his next words were muffled by the dog's muzzle which tilted to the side and opened, clamping around his muzzle. Rubbery teeth held his cheeks into the muzzle as a thick tongue slipped past his lips and invaded his muzzle. Matthew's eyes grew even wider and begged for Stag to let him go and help defend him from the creature behind him. But the dog only pushed into the kiss and pressed his tongue ever further into his muzzle.

Shane watched as his dog kissed the man, his fingers collecting a couple drops of pre in the meanwhile. He reached around the man and dabbed the musky liquid on his nose, calming his victim even more. Matthew no longer struggled in the kiss, but instead accepted it. He even closed his eyes and let out a muffled moan.

The panther took it as a sign and moved around back, letting his leathery, barbed member rub against the warm cleft of the man's lightly hairy rump. It was cute, and just the right size for grabbing . He teased Matthew, letting his soft, rubber barbs roll over the sensitive hole as his shaft slide up and down the cleft.

Stag finally let go of the kiss, lapping wildly at his former owner's face. "Please," Matthew started before he groaned happily at the feeling of that member against his backside.

"Please, what?" Shane asked before he slapped the man's rump, then angled his member so the head pressed teasingly against his hole.

"Please," Shane said again and found his protest quickly fading. Each time he breathed in, he knew he wanted this. His defenses were crashing and all he could sense was that masculine scent, his quivering sphincter and the lapping of the new Stag against his face. "Please, fuck me."

Shane obliged with a thrust, pressing the barbed head of his shaft into the man's backside. It was tight, though not as tight as Stag's. He could change that though. It was hot too, and slicked easily with his copious preseed leaking from his shaft. He pulled back out, then pressed in, each time driving his shaft deeper into Matthew's passage, his barbs teasing the man's sensitive prostate.

Matthew could not believe how hard he was. He was dripping on the floor, splattering his pre over the puddle that was his dog, flicking it against the glass of the sliding door when he was forcefully thrust into. He loved every minute of it. He let out a loud moan as he swung his head around, kissing his dog fiercely as he shoved his tongue into that rubbery muzzle. It was a heavenly taste that tingled on his tongue. All he could do was grunt and groan into his dog's muzzle as the panther plowed his ass, giving him the fuck of a lifetime.

Stag enjoyed the kiss thoroughly, he even let the wrists and hands of his former owner go as he reformed. Matthew's body straightened slowly as Stag grew to his former owner's height, but there was not enough room for his body to form completely. Instead, he looked to be halfway forming out of the glass. Not that he minded, he was all too happy to do anything for the man's affection and let out a soft bark as their member ground together.

Shane held onto Matthew's hips as he rose, the angle better positioning his member to press against the man's prostate with each thrust inwards. He could sense the man's body under him tensing, his breath picking up as he racked with lust. It drove Shane wild knowing how much pleasure this man was getting from him, knowing he would have one more to add to his pack.

He bit down on Matthew's shoulder with rubbery teeth that only applied pressure to the skin and Matthew broke the kiss for just a moment to fill the large room with his loud, long moan. His body was shaking with the amount of pleasure coursing through it but Shane only pushed harder, thrusting into him with urgency. He could feel his member pulsing in the man's passage, filling it each time he pressed in. The amount of pre that leaked from his shaft was now making lewd squelching noises.

It was Stag that was the first to go though. His canine shaft throbbed heavily against his former owner's and he howled softly as he felt himself explode. Black, liquid rubber cum burst from his rocket, splattering himself and Matthew in the process before it was absorbed back into his body. He lapped at the man's face, his member still pumping and throbbing.

It drove Matthew wile who was the next to spill his load. He grunted, feeling that member pulsing against his and urging him to have the hardest and longest cum of his life. The first wad hit Stag's muzzle, the dog quickly slipping his long, dextrous tongue out to lap up the musky liquid. The next few splattered against their chest and ran down to their bellies. It was not long before it only dribbled out of his cock and over his dog's which was still inflated thanks to the knot at the end. He could feel his cum dripping off his balls and pooling at his feet when Shane thrust himself one last time into his awaiting ass.

Hot, thick cum filled Matthew's passage as Shane orgasmed. His cum sprayed against the silken walls, soon spilling back on his shaft as it leaked from the tight hole. He lazily pulled out and thrust back in a couple times before he laid against Matthew's back and panted softly into his ear. The panther could feel his eyelids growing heavy as he let out a contented sigh, then realized something peculiar.

Matthew was not changing.

He lifted up, his member slipping from the man's hole with a pop before he turned Matthew around. Stag hugged him, his arms fusing into a locked grip as his still-hard shaft rested against Matthew's warm cleft. Stag just licked teasingly at his former owner's ear as the man giggled softly and smiled.

"That was fantastic." Matthew said, his hand lightly stroking his wet prick.

"That's strange, shouldn't he be changing?" Shane asked Stag as he crossed his arms over his chest, his dog just shrugged his shoulders. "But I changed you just through sex. Granted, it was with my tail, but my cum should do the trick too." He was not sure how he knew that, he just did.

He heard Stag let out a little whimper and the dog averted his eyes a little. "What's the matter, pup?" He asked, reaching over to rub behind one of the sheppy's ears. Stag loved that too much for his own good.

"Well, um, I had," the dog was muttering as he replied, "ate a toy earlier, a rubber toy."

It suddenly struck Shane. "Well, that makes sense." He said to himself. He could change any individual in many different ways, but he needed a catalist to start the transformation. He needed something synthetic. Something like Matthew's cycling shorts. Shane just smiled and turned around to walk to Matthew's bedroom. "I'll be back, pup. Don't let him go just yet." His dog obeyed, almost making a suit of himself as he held his former owner against the wall from the neck down to his feet.

Shane stepped into the bedroom and looked around for a moment, but there was no hamper, nor was there a set of spandex shorts. It was probably in the wash, but he had to have a spare around here somewhere. Shane walked to the closet and slid the doors back. It was full to the brim with different clothes from jeans to slacks, polos to dress shirts and even a couple suits. But there in the corner, off by itself, was the perfect item.

He chuckled as he lifted the wetsuit off the hook and removed the hanger. He flung it over his shoulder, hand gently stroking the smooth fabric of the suit. While the inside of the suit was made of neoprene, surprisingly the outside was a blended with spandex to give it a sleeker finish. The thing was well made, expensive too, and it would make the best catalyst for the transformation. He could feel his member stiffen just at the thought and idly rubbed it as he walked down the hallway and back to the open kitchen.

Stag and Matthew were kissing again, the man's shaft standing proudly in front of him still slicked by his last orgasm. They stopped making out when Shane approached and the dog's eyes lit up at the sight of the wet suit. His body parted from around his former master's like a zipper being pulled the length of his body, releasing him from his rubber prison.

"Here, get dressed." Shane said in a firm tone and smiled as Matthew complied, his musk seemed to be some potent stuff. As he watched Matthew slipped a leg into the wetsuit, Stag stepped over to stand beside him. The dog cuddled up to his side and gently wrapped his hand around his shaft, stroking the feline cock slowly which earned a smile and a pat on the back.

Matthew was too intoxicated with the heady, musky scent still filling the air around him to give up much of a fight. He slipped his other leg into the neoprene inside of the suit and felt his member brush up against the lining. He shuttered and let out a shaky sigh as he ground himself against it. He loved that suit, though there were so few places to actually use it. He had mostly just worn it for the feel, for the look. He slipped both his arms in and pulled at the tight suit which formed well to his muscular body.

It was always tricky adjusting the suit to be just right, but the more he adjusted it, the more overwhelmingly horny he became. He almost came again right in the suit and probably would have if he were told to. He could not keep his eyes off the spandex and rubber god in front of him, envying the dog who was now nibbling on the side of his neck.

Matthew reached his arms back and carefully lifted the zipper, it always had been the tricky part. "Can you help me out?" He asked the panther and turned around. Shane stepped up behind him, his shaft pressing against the fabric covering his ass as he zipped the man up the rest of the way. His hips rolled as he slid his cock over the smooth fabric clinging to those perfect, rounded mounds of muscle, his hands resting on the man's hips. Matthew closed his eyes and moaned as the panther nibbled on one of his ears, stroking himself through the suit all the while.

"On your knees, boy." Shane whispered into his ear and Matthew just nodded, slipping down to his knees. Shane and Stag walked around to his front, both engorged cocks at eye level and dripping that special, intoxicating preseed. He wanted to suck on both of them then and there, wanted so badly to fill his mouth with their cocks, but he waited and watched.

Stag and Shane grabbed their members and began to stroke as the stared down at their soon to be new recruit. He was already obedient as could be, his mind lost in the haze of their scent. It drove Shane wild thinking of how easy it would be to turn others like he had Stag and Matthew. How easy it would be to build an army of synthetic, hyper sexed beings. He felt his hand being pushed away from his member as Stag grabbed it, stroking firmly.

Shane let out a pleased groan and did the same, wrapping his fingers around the tapered shaft of his faithful pup. He looked over to Stag, getting a face full of tongue before he caught it in his muzzle and suckled, feeling it lengthen to tickle his throat as he kissed his dog. His tail swayed behind him, morphing at the tip into a replica of his member before he slipped it under the tail of his pup and invaded that fine, rubbery ass.

Stag broke from the kiss and moaned, feeling that tailcock pressing into him, tickling his prostate as it shoved its way in. He could feel his body tensing, the expert fingers of his master working his cock, quickly pushing him towards the edge of orgasm. It was not long before he felt his knot beginning to inflate, Shane's hand squeezing at it. The dog broke the kiss as another orgasm washed over him, his seed spraying against the face of his former owner, coating his cheek and splattering across his lips.

The black rubber cum dribbled down to the wetsuit, more spraying on it as Shane angled the spasmming cock down, letting the cum paint the man's chest. He could feel his own orgasm coming, the tightness of the dog's passage somehow being transferred to his own shaft. As his pup's hand brushed over the barbs at the tip, Shane too began to cum.

It splattered the other side of Matthew's face, dribbling down to that wetsuit. He sprayed his seed onto the man's chest, down to his belly and even across his crotch and legs before his orgasm finally died. He stood there, arm wrapped around his pup, tail still lodged inside that tight passage as he watched the wetsuit begin to crawl over the remainder of Matthew's body.

It spread up his neck with tendrils that creeped and rooted themselves to his skin and hair. His hands were engulfed easily by the black neoprene and light brown spandex that covered the backs of his hands and fingers. The neoprene made a non-slip grip on his palm and fingers, mounding a little to make a defined pad on the tips. It also spread between his fingers, oddly enough, fusing them all together with a thin web of neoprene.

The same happened with his feet which slowly morphed into a paw-like shape tipped with neoprene claws. Matthew just moaned, the suit now almost entirely covering his face before he bent over on hands and knees. They watched as a mound formed just above his rump, his spine stretching out as a thick tail formed from the suit. It tapered into a rounded point almost as long as his legs were, the underside black neoprene, while the upper side was that same light brown spandex.

Shane helped the transforming man back to his knees just as a muzzle was forming on his face. It was stubby and rounded with a thick nosepad resting on top and whiskers jutting out the sides. His ears had also shifted to rounded mounds on top of his head. Shane had to admit it was the most handsome creature he had seen.

The new river otter gripped Shane's paw and helped himself up to his webbed feet, looking down his body. Between his legs stood a still impressive member, larger than he had before. It was a tube of spandex from base to tip creating a hood that held the neoprene head hidden within. He also had a pair of sizable balls, he could feel the wight as they churned out new, potent seed.

His suit soon covered his bits up though. A mound of darker brown spandex stretched over his package, making a lewd outline of the monster cock hidden within. A waistband of neoprene hugged his hips and just above his rudder tail while two more neoprene bands slipped around each of his thighs. The jock was the perfect cover for the otter, showing off his junk while framing that handsome ass of his.

"Welcome to the club, otterboi." Shane said as he hugged the otter to him, his own member slipping back into his suit. Stag hugged the otter from the other side, sandwiching him between them.

"Thanks, Sir." The otter said softly and let out a gentle churr as nuzzled into his master's neck. It was an amazing feeling being hugged by such handsome creatures, by his brothers. He could not wait to find more to transform. The three of them was just the start.
