*** Personal Training ***
Grayson stepped out of the Jockhole's changing booth. The baby blue posing thong looked silly on his lanky 55kg/121lbs frame. He slipped into his tennis shoes and walked around in front of the wall mirror.
The shopkeeper gestured at a display case. "Hey Grayson, need some body jewelry?"
The teen looked down his flat pecs where nipple rings poked out a bit comically. "I'm not even sure I like the ones I have," he said past the tongue stud he wasn't quite used to yet.
The vendor shrugged. "If you lift a few weights, you'll see it fits much better. There's a gym across the street. Let them know Ace sent you."
"Hi, I'm Niu. How can I help?"
Grayson felt silly in the middle of buff and cut men who knew exactly what they were doing on the machines. "Ace sent me over. He thinks the thong would fit better if..."
"Yeah, just pick an exercise you'd like. I'll give you some personal attention."
The boy, Niu, who wore nothing but a red thong, stepped around the counter.
Grayson nervously rubbed his Jockhole tattoo that ran down his flank. "Shouldn't I put on a shirt or use a towel or..."
"Nah, I'll let you know what you can and can't touch. Pick a spot to start."
"I uh... I guess..." Grayson sat down at the leg raise machine. His posing thong was loose on his stick legs with a hamstring circumference of 30cm/11.8inches.
Niu picked the weight and Grayson struggled to straighten his legs. The second rep was easier. The third one easier still.
"You're getting the hang of it."
"I'm not doing much," Grayson said.
Niu grinned. "Positive reinforcement. You'll want to come back if you associate training with... good things."
Grayson raised his calves again and his dick rose with them. Over the course of three reps, his posing thong was tenting strong enough to be noticeable.
"Keep it up," Niu said and the training boy felt as if the thong's silky fabric caressed his dick head like a human tongue.
Grayson grunted with each rep but less from struggle and more to mask the whimpering that threatened to escape his lips.
His legs were squished together. He had ham strings big enough that he needed to spread the legs a bit more. Niu increased the weight.
Grayson grunted louder and louder, but it couldn't keep the pleasure from surfacing. With grimaces, the teen squeaked pathetically as the approaching orgasm shook him.
Niu increased the weight again and Grayson screamed with every vein popping as he held the cushioned weight bar at the peak. His poser was darkened by the cum shots it caught before the white cream ran past and along his massive quads.
Grayson stepped off the machine with shaky legs, white goo making its way down his 64cm/25inch hamstring muscles.
"How do you like the positive reinforcement approach?"
"It's great," Grayson said, out of breath and slightly hoarse.
"Keep going, I'll be right back with you."
The quad-zilla teen swaggered to the next device – a leg curler.
As soon as his legs touched the cushioned bar, his dick leaked again. Almost clean drops of pre-cum ran down to his mega-glutes.
When he brought his legs in, he felt his calves flare out and grow to match their upper legs. He also felt the return of the thong-blow-job on his now slightly more sensitive dick.
More in control now, he wasn't screaming anymore when he cummed but his painfully rigid dick slipped past the poser and sprayed white goo across his abs.
How embarrassing. Other men and boys watched with smirks and chuckles.
Grayson stepped off the machine. He had spent too much time on it and now his calves were out of proportion with his quads.
Niu came back to the quad-zilla turned calv-lamity.
"Here are some supplements and a Hydrator to keep you going."
Grayson took the offered pill. "What are those?"
"Shredded Cock's very own brand."
The leg-heavy teen swallowed the little pill dry. He felt a light rush as blood went from his brain to his dick.
What had been a tent before – barely covering the erection – now had trouble holding in as much as Grayson's dick head. His tool was so big it had gone nearly soft again from the lack of blood to fill it all.
The thing the size of two stacked soda cans, dangling between his mega-quads, rose again with its veins popping more and more... and more.
Every vein on Grayson's body was at least somewhat visible when he flexed, but his cock was truly shredded as if it were an overtrained muscle.
"Come on," Niu said. "You did so well on the legs. Let's see what your arms can handle."
Grayson flexed his wimpy arms, letting his biceps peak at 20cm/7.8inches before giving up.
At the free weights, Grayson picked a spot between two better looking men, because Niu put him there. He wasn't comfortable standing there, looking weak, as naked as possible safe for the stretched poser covering his dick head, full of cum shots.
Nervously, he took a long sip of Hydrator.
Before he knew what was happening, he pissed hard enough from his erection that the stream sprayed off the mirror.
The men at his sides dropped their weights and ducked away.
"S-sorry," Grayson said and tried to keep the piss in to no avail.
He grabbed his dick and pressed it close to his body, only pissing up his torso. At least it washed away the cum.
"Time to lift," Niu said. "Let's see what you've got."
Grayson grabbed light dumbbells and did two curls before deciding he needed more weight. This process repeated until he was at the middle of the row, lifting dumbbells 12 times the weight he had started with.
A full erection of his shredded cock reached most of the way up his abs. Pre-cum was deposited on those abs and ran down the cut between them like a drain into his poser.
He took care to lean back when he orgasmed, spraying through the thong and caking his chest with goo.
He put the weights back and took a swing from the bottle, to piss away the cum.
Grayson took a look around. Several men were wet with piss but nobody was a messed up and near naked as him.
He felt a bit too exposed, but he gave himself a quick flex in the mirror, admiring his 45cm/18inch biceps peaks.
"Well done," Niu said. "Let's hit pecs now."
Grayson followed the other teen, feeling positively reinforced.
The teen bodybuilder lathered up his sticky body in the corner of the locker room.
His now limp dick slapped from quad to quad as he stepped under the hot stream. Grayson rubbed dry sweat of his face and hardly noticed a few hairs flowing through his fingers.
Swaggering out of the tiled corner with all his 87kg/191lbs, Grayson flexed at the mirror. Had the shampoo washed out any of his hair color? No, the palm-sized circle on his head that was the only spot not shaved clean still had its baby blue glow.
Grayson packed his dick into the posing thong as well he could and headed home.
*** Two Dongs ***
Glyn had slipped into an E-Z-Grow jockstrap and a stringer top. He approached the bench press machines.
One was taken by a decently handsome jock with a teal undercut. Another one was just freed up by a blond kid about Glyn's size.
"Hey," Glyn said to the blond boy. "Could you spot me for a sec?"
"Sure," the boy said.
"I'm Glyn."
"Theo."
They fist bumped.
Glyn laid down just as the receptionist, who wore only a red thong, whisked by with a mop, cleaning the many wet stains on the floor.
"Man, Ace, I don't get why I have to do that," he half-mumbled toward the teal haired jock.
Glyn started bench pressing but still had one ear out for the conversation.
"Doing normal work keeps us grounded," the man called Ace said. "Just because you're a reality bender doesn't mean you can have everything you want on a whim. Of course, if you got better at bending, you could put a property on the floor so it stays spotless."
"Ugh," the receptionist made. "I can barely create stuff, let alone make permanent changes. I have a mind specialty. I should just make a slave to do the boring work for me."
Ace shrugged before he laid down for more bench presses. "If you find someone already willing to serve, that could work. But making a permanent mind change is still tricky. How's practice?"
The teen with the mop grunted. "I'm too busy with the move. Breaking old ties and becoming part of the bender community takes some time. I wish I had a space-bender roommate like you. My apartment isn't exactly worthy of a living god."
Ace finished his set. "I can ask around. I think there's a bender with a specialty for meticulous changes or something. Unless you're among the upper echelon of benders, you still need friends to live like a god. Probably for the best."
Glyn had finished, thanked Theo and was about to walk away from the weird conversation.
Ace spoke behind him with a chuckle. "Where do you think you're going? Niu, test your abilities on these."
Glyn and Theo looked at the receptionist who squinted at the space between them.
Niu nodded to himself. "Switching smarts is a bit tricky, but here you go."
Glyn's blinked away intrusive thoughts about algebraic concepts and programming languages he had never heard of.
Looking to the side, he saw Theo with his mouth hanging open and almost cross eyed.
"H-hey," Glyn said. "Buddy, are you okay?"
Theo looked over, slow and unfocused. But he grinned. "Yeah fuck. Man, I'm fucking okay."
"You... sure?"
Theo nodded and drooled slightly. "Yeah, bruh. I'm the horniest fucking cunt in the fucking house, man. Fuck."
Niu waved dramatically.
Theo's face grimaced as if he had violently woken up from a dream.
Glyn didn't think about it – or anything. He wanted to lift, eat, maybe fuck. Theo was kind hot...
"Ey, sexy fucker," Glyn said. "Wanna bang?"
Theo looked scared. "I believe something unusual is going on here."
"Yah, sure fucking is," Glyn said and slapped his crotch. "You bitch boy is fucking sexy and shit. Wanna ride?"
"This is caused by you," Theo said and pointed at Niu.
"Fuck, man," Glyn said. "Come on, bro, wanna fuck or nah?"
Ace chuckled, waved and...
Hadn't they just been talking about something? Glyn felt like there had been an important conversation but it was slipping like a dream.
Ace stood up. "I'll grab a few things. Keep them around."
Niu dropped the mop. "So you two, want some free sweatbands to keep the eyes clear?"
"Sure," Theo said. "I was about to go do deadlifts."
Niu grinned. "Want to borrow a belt?"
Glyn had gone to the reception desk with Niu where Theo had received his belt. The blond boy had grunted upon taking it and looked down at his crotch, where a chastity cage was clearly poking the jockstrap.
Glyn himself had gotten a one-time free supplement.
With his shredded cock that dangled between his legs, barely contained, and Theo's obviously caged dick, the two walked to the deadlift rack.
Both put on their free headbands, looking at the mirror.
Gl... Dong-Yul found that it kept his forehead dry and his hair out of his face. Just like the other guy's pitch black hair. Theo... no...
"Sorry, what was your name again?"
"Dong-Jin."
"Funny. I'm Dong-Yul."
"Ha, we're two Dongs, I guess."
"Let's see how much weight two Dongs can deadlift."
The `two Dongs' headed for the shower at the same time. There was only one shower head.
"Um, Dong-Jin," said Dong-Yul.
"Yeah?"
"You mind if we... conserve water?"
The caged `Dong' grinned. "Just what I was thinking."
They stepped under the stream, fingers on face and nipples, making out passionately. One Dong's shredded cock rubbed its way under the other Dong's caged package and between his legs.
"Fuck me," whispered the caged Dong.
"W-we don't have lube."
"See if the shampoo works."
They soaped up, mostly focused on Dong-Jin's hole.
"What if someone come's in?" asked Dong-Yul.
"There's a wall."
"It takes literally one step to see past that. I promise I'm bursting with cum, too, but..."
The caged boy turned around and spread his cheeks.
Dong-Yul worked his monstrous, shredded cock into the hot, pulsing hole without further comment. Someone entered behind them. Dong-Yul didn't care. He pushed the head in and reveled in the pained exhale it caused in the caged Dong.
Each quirk in Dong-Yul's dick veins was a ripple to push past the quivering, flexing sphincter.
He held onto the trembling boy's hair (Had it always been a mohawk?) and pushed slowly but persistently.
The door behind them opened and closed again.
By a near miraculous turn of events the shredded cock of the bigger Dong slipped into the pulsing hole – all the way.
Wait, when had Dong-Yul gotten a whole head taller than his little friend? How had he not noticed the difference before?
With a long grunt, the more muscular Dong-Yul pushed all he had got into the twink-ish caged Dong.
That was the start of hot Dong on Dong action.
Big Dong humped the smaller one into the wall, making the dick cage clank against the tiles. Again, someone entered or left or both.
Hair ran past Big Dong's face as he aggressively moaned into his fuckee's ears. He brushed it aside, rubbing over his completely smooth scalp.
Again, he grabbed Small Dong by the hair and put the other on the twink's narrow waist. He fucked with the point of entry right under the stream to make it splash as much as possible.
"F-fuck... me..."
"Fuck you?" Big Dong said.
"Y-yeah, please..."
Big Dong punched Small Dong in the head. "Bitch, the fuck you think I'm doing?"
"S-sorry. Fuck me harder."
Big Dong brought his mouth right up to the little ear in front of him and growled. "That's more like it."
He grabbed the twink by the hips and thrusted as if trying to vanish into the tender ass.
More people using the door. Dong-Yul couldn't help but throw a quick glance back.
Four beefy men were watching, plus the guy called Ace, who stood in the door frame and kept the door open to let the gym see inside.
Big Dong turned forward again and asked, "You like that?"
His twink bitch answered. "Yes, fuck, yes. I love that monster dick. Shred my hole!"
With hormones flying high, the sex was already nearing its end, so Big Dong shouted, "Gonna shoot my load up those bitch guts."
"Yes, please. Fill my slut hole with man cream."
Big Dong grunted as he unloaded so hard, his eyes rolled back into his head and his vision went black.
Only the sound of running water filled the room as Dong-Yul held perfectly still, while his bitch's hole still pumped and drained his spent monsterdick.
With a deep sigh, he pulled out and stepped aside to let everyone see cum shot after cum shot squirt from the embarrassed twink's rear.
He rubbed his dick off in the shower stream and slipped right into his clothes, while Small Dong still had to let his hole drip, desperately trying to speed along the cleanup, now painfully aware of the audience.
When Dong-Yul was clothed in his jockstrap and tank top again, he flexed at the mirror behind the crowd. Dong-Jin was still rubbing his sore hole and only now stepped out of the shower.
In the mirror the bald hunk noticed the "Big Dong" tattoo on his pectoral, which was in the same font as the Jockhole tattoo on his lower back.
Funny that he had randomly run into a boy with the exact same tatts, safe for "Small" instead of "Big".
Ace stood up and reached out. "Here are some socks. I think your old ones are too smelly."
"Wow, thanks."
"No problem. You put on a good show."
The two Dongs slipping into their new socks, each one having a down arrow on... No, they were pure white.
Big Dong looked over to his fuckee, both their mouths hanging open, on the verge of drooling. There weren't many thoughts in his mind.
"Ey... Good fuck, bro," Big Dong said.
"Yeah... it was like... good, and shit, bruh."
"Yeah, fuck. Good fuck, man."
"Fuck again later, bro? Hole fucking sore, but later... fuck."
"Yeah, sure. Fucking good fuck, that one, bro. Ha. Haha."
As they stepped out into the gym, leaving their audience behind, Niu jumped into their path.
"We're closing," the receptionist said. "As soon as everyone's out, I need this place cleaned. The floor is full of sweat and piss and cum. You two are going to do the cleaning."
"Bro, what the fuck?" Small Dong asked.
"Yeah, fucking... what the fuck," Big Dong said. "Like we ain't clean, like fucking..."
"You were caught having sex in the shower. Either you clean or you're not allowed back in here."
"...Kay, where's the mop?" Big Dong asked.
"No mop. After your little display, you need to rehydrate. There's plenty of fluid around."
Small Dong got down without hesitation and started licking a piss puddle. Big Dong shrugged and crouched next to a chest press where cum was drying on the seat.
They licked all night, only stopping to fuck.
Next time we meet some different benders and the gym gets an upgrade.
