All three of them had started working at the company. The only difference now was that they did so voluntarily—and with pleasure. They no longer needed the hypnosis perfume to strip naked and engage in lewd acts. Hyeontae never failed to encourage their transformation, always praising their progress. Whenever they crossed paths in the company, they’d exchange brief greetings before going their separate ways. None of them lingered to ask how the others were doing—they all knew each other was busy, and enjoying themselves.
One day, Hyeonjun spotted Jihun in the hallway and called out to him as they passed.
“Jihun, it’s been so long.”
“Yeah… hasn’t it? You look good.”
Both of them were nearly naked. Hyeonjun wore a red collar around his neck. His nipples were swollen, his areolas noticeably larger and a deeper pink than before. His lower abdomen was round and distended. Jihun glanced over Hyeonjun’s body, murmured that he looked good, and tried to walk past—but Hyeonjun grabbed his wrist.
“Wait, I have something to ask. Jihun, my dad wants to go camping. Wanna come?”
Now, Hyeonjun naturally referred to Hyeontae as dad. Jihun paused mid-step and turned back. The employee badge dangling from his nipple piercing swayed against his chest. His bronze skin, despite spending all day indoors, still glowed with healthy elasticity. He hadn’t slacked on exercise—his muscles remained well-defined, thanks to the company’s fitness center, a perk for employees. While regular staff had access to a standard gym, Jihun frequented the special one—where workouts were designed to enhance sexual sensitivity. He’d been on his way there when Hyeonjun stopped him.
“Camping?”
Now that he thought about it, Hyeontae had once casually mentioned going camping together. Jihun had assumed it was just idle talk—he hadn’t expected an actual invitation.
“Sure, I’m in. When?”
“Probably in a week? Dad said everything’s ready, so we just need to show up.”
“Who else is going?”
“You, me, and Seungjun? I haven’t asked Seungjun yet. You okay with him coming?”
“I don’t care.”
Jihun had mixed with Seungjun’s body plenty, but they were still awkward around each other. Back at Hyeonjun’s place, they’d been under hypnosis, and at work, they barely crossed paths. When Jihun thought of Seungjun, the first things that came to mind weren’t conversations or shared moments—it was the sounds of their bodies tangled together, the moans.
“Got it. I’ll ask Seungjun… Where were you headed?”
“The gym.”
“Oh, the one on the 10th floor? Nice?”
“Decent, I guess.”
“Mind if I check it out?”
Jihun shrugged at Hyeonjun’s request. The elevator ride up was silent. When the doors dinged open, Hyeonjun gasped. He’d expected a typical gym—rows of treadmills, like in ads—but instead, the space was eerily empty. The only thing in sight was a massive, heavily tinted glass door.
“Oh, you’re not registered for the gym, so I’m not sure if you can get in.”
Jihun pressed his employee badge (attached to his nipple piercing) against the sensor, and the door slid open. Grabbing two towels, he turned to Hyeonjun.
“Go register on the 9th floor. It shouldn’t take long…”
“I was just gonna watch… I’m not really into working out.”
“Come on, just register. It’s free.”
Jihun disappeared beyond the glass door, leaving Hyeonjun grumbling. Fine, I could’ve gone in with him… Too impatient to wait for the elevator, he took the emergency stairs down to the 9th floor.
“Uh…?”
The 9th floor did look like a standard gym—except everyone was fully clothed. Must be for regular employees. At least it was nearly empty; most staff were working during the day. Hyeonjun, used to being naked, felt oddly self-conscious as he covered himself and approached the counter. A tall, muscular man looked up at him.
“Uh… I want to register…”
The man handed him a terminal. Hyeonjun entered his name, age, and department—or tried to. The screen changed before he could finish, asking whether he wanted to use the 9th floor or the 10th floor.
“What’s the difference…?”
“The 9th floor is for general employees. The 10th is restricted to certain departments.”
“I’m not actually an employee…”
Panicked, he stammered. He’d left the department field blank, but the system had still processed his request. The staff member, who’d assumed Hyeonjun was an employee based on his nudity, raised an eyebrow.
“Then…?”
Hyeonjun scratched his head awkwardly. “I’m the president’s son.”
“Ah, I see. Go ahead and choose whichever you’d like. I’ll handle the department registration.”
The man’s demeanor shifted instantly at the mention of Hyeontae. Since Hyeonjun’s only goal was to watch Jihun, he selected the 10th floor. The staff member took the terminal back, filled in the remaining details, and handed Hyeonjun a fitness band.
“This is your registered fitness band. Wear it, go up to the 10th floor for a body assessment, and follow the instructions for your workout.”
“Can I get in without an employee badge?”
“The fitness band will work just fine. No need to worry.”
Hyeonjun bowed slightly in thanks and headed back up. Like Jihun had, he pressed the band to the sensor—and the door opened. Beyond it was a locker room.
“Hmm… since I’m not wearing clothes anyway, I guess I don’t need to change.”
He’d never been much for working out. The only physical activity he’d done was what Hyeontae had conditioned him for. He’d only come to watch Jihun, not to exercise himself. Still, just in case, he grabbed a towel.
“……”
Stepping inside, he understood why the gym wasn’t directly accessible—why there was a shower and locker area first. The space was filled with well-built, sweaty men, all naked… but they weren’t doing standard workouts. Moans filled the air.
“Ahnngg—!”
“Hah, h-uhh…!”
Some were getting their asses pounded by machines, others rode massive dildos, grinding their hips. Hyeonjun stood frozen. This was definitely not a place for him.
Every man here had bronze skin, muscular bodies, and—impressively large cocks. Hyeonjun, slender and fair, stuck out like a sore thumb.
“Oh, you’re here?”
Jihun, already drenched in sweat from whatever he’d been doing, was the first to notice Hyeonjun’s wide-eyed scanning of the room. He took a swig from the water dispenser.
“Yeah… they gave me this when I registered.”
Hyeonjun held up his fitness band. Jihun showed his own—the only things either of them wore, besides towels. Their chests heaved with every breath.
[Anal Development Session Initiated.]
A mechanical voice chimed from Jihun’s band, accompanied by a beep.
“Ah, I gotta go work out. Catch you later.”
Hyeonjun watched dumbfounded as Jihun left. A trainer—equally burly—approached him.
“First time?”
Even the trainer’s physique was intimidating. Hyeonjun tried not to stare at the man’s erect, swinging cock.
“I’ve had a lot of body checks before…” he muttered, thinking of the endless exams in the research lab—nipple development, ovulation tests, all of it.
But the trainer was firm. “Those were for general health. Here, we assess fitness potential—how to improve your body.”
He handed Hyeonjun several condoms. Confused, Hyeonjun took them and glanced around the office-like room. It was cool from the AC, filled with strange devices.
“Put this on, spread your legs, and sit down. Then clench your anus as tight as you can.”
Hyeonjun followed instructions. The probe was thinner than what he was used to, but still rigid.
“Ngh… haah.”
“Good. Hold for 5 seconds… Okay, you can get up.”
The trainer checked the readings, then removed the condom. Next, he directed Hyeonjun to another device—a thick, vibrating dildo—to test how many self-pistons he could do in a minute. They also measured nipple sensitivity and erection hardness. By the time the assessments were done, Hyeonjun’s ass burned from being stretched, and he was panting, fully hard. The trainer, unimpressed, delivered the final evaluation:
“Last one. We’ll test your ejaculation volume.”
