The Average Size Secret
As I scrolled through the internet, the average size of male genitals turned out to be all anyone needed: a single roll of toilet paper. You get an erection, shove it inside, and that's it. If the tip just pokes out a little, you're average. It's tight but not painfully so—just about right in girth.
This morning, right after waking up and stepping into the shower, the thought hit me like lightning. I couldn't stop replaying last night with Kim Seoa and the deep, hungry kisses with Jin Ayoung. My body responded instantly. A little hand work was all it took to bring me all the way up.
The second I pressed the stiff, fully aroused cock against the used toilet paper, every filthy word Kim Seoa had whispered before she sucked me off flashed through my mind. Her lips had curled into a teasing smile as she called me big. My grin spread wide before I could stop it. The massive cock I was holding was already a good inch ahead of the paper. The swollen head had popped free completely, and the base of my shaft was just starting to peek out.
This was the genetic jackpot—bigger than average, sharper jaw, better skin, and a height that made people look up. I laughed out loud. Yeah, sure, I got the short end of the stick on everything else, but at least my dick was a walking advertisement.
Twenty-nine years old and I finally felt this good? I hadn't even been the top in my class; my average was a sloppy 3. If grades were what counted, I was basically useless. But a big cock? That was something I could brag about.
Singing to myself, I strolled into the shop. Shin Iseol was already at the counter, her face twisted in pure displeasure. When I glanced at the mirror beside her, I saw it—pure, unfiltered smugness. No wonder I felt amazing. The women who worked here were about to learn exactly how lucky I was.
“Looking for another weird prank again?” she shot back, voice dripping with sarcasm.
“Prank? When have I ever played a prank on you, Iseol?” I tilted my head innocently. “I can’t think of any.”
“…” She huffed. “Fine. Whatever. Today’s schedule—two clients. One is Park Yuyoung. The other is the executive director and his partner for a hot-stone massage.”
“Oh?” I raised an eyebrow. “What’s the executive director’s name?”
“Who? Lee Mikyeong? You don’t even know the client’s name yet?”
“I didn’t tell you.”
We bantered for a while, trading barbs like old pros. She’d called me last night, sounding annoyed, but I hadn’t picked up. Another text, another late check—classic Shin Iseol. Still, when I pieced together her questions, I realized she was probably the most curious person in the shop about what I was really doing.
The training I’d gotten from Jin Ayoung yesterday clearly worked. I could already feel it: the subtle shift in her tone, the way she kept circling back. She was definitely in that sweet spot where she wanted to know more but didn’t want to admit it.
I flashed my most confident smile and gave her arm a light, casual squeeze.
“Sorry about the coffee offer earlier. I’ll buy you one next time.”
She crossed her arms. “I only drink Starbucks. Nothing else.”
“There’s no Starbucks around here~ I’ll make you mixed coffee. My hands have a magic touch.”
“…Mixed coffee is one thing, but how does hand massage even matter?”
I wiggled my index finger playfully. “When you mix it, you stir at the end. I swirl it with my fingers.”
Her cheeks flushed. “Hah, you—”
I strolled off toward the staff lounge, leaving her sputtering. Behind me I felt her eyes burning holes in my back, but I didn’t turn around.
The lounge was empty. I sat in the corner, pulled out my phone, and checked my messages.
- Shin Iseol: I’m never drinking coffee from Junhyun again - Jin Ayoung: It’s cold out today, so dress warmly. - Kim Seoa: Reply, okay? - Meobal S Group Chat: Schedule for today. Everyone please check and reply. - Lee Yeondo: Then let’s meet at Hapjeong at 8 this Saturday…
Kim Seoa had asked for the shop address last night. I’d forgotten to reply and passed out. Now I was going to drag this out for twelve more hours. The girl who used to treat me like a walking flat butt was now checking my replies like a starving stray. I smirked.
Lee Yeondo had only liked the message; no reply. Smart. With so many women in my life already, I wasn’t rushing anything. One slow, careful conquest at a time.
I ignored the rest and replied in the group chat with the day’s instructions.
The door opened. Choi Wonjae stepped in, spotted me, and grinned ear to ear.
“Good morning!”
“Good morning, Director.”
“Early again?”
“Yeah. Figured there might be something I could help with.”
“Ha ha ha! Looking at you makes me remember when I was your age. I used to work my ass off. Now… I don’t know. I feel like that fire I had back then is gone.”
He started humming as he scrubbed the sink.
I had to admit, seeing me this early made me feel good too. Almost like I was still that desperate kid who would do anything for a shot.
“Ah, right. You’re taking over Park Yuyoung’s case?”
“Word is Shin Iseol pushed for it.”
“Yeah? She said that?”
“Ha. Well, she did ask me to.”
“Social life is part of the job. Don’t feel embarrassed. As long as you’re serious, I welcome it. Just don’t slack. I know you won’t, but still.”
“Got it! I’ll work hard!”
He clapped my shoulder.
“Anyone who sees the girls naked—does it turn you on or freeze you up?”
“Huh?”
The sudden question caught me off guard. It felt like someone had just dropped a live grenade in my lap.
“During observation classes everyone covers up properly and wears underwear, but Park Yuyoung is getting a full-body skin treatment. She’ll be completely naked when she comes in.”
My mind spun through a dozen worst-case scenarios. This was way more exposure than I’d planned with Kim Seoa.
“Don’t worry. She’ll be lying face-down on the bed, and we’ll keep her ass covered. Just do the same massage you always do—pay extra attention to every spot your hands can’t reach.”
I swallowed hard. I couldn’t even picture it in detail yet.
Wonjae smiled proudly. “We’ll see you at Lee Mikyeong’s hot-stone session later. Special.”
***
Even though Wonjae had said he was confident, I could tell he was nervous. Before Park Yuyoung arrived, he told me to practice on one of the staff.
Same room, same setup.
While the team prepared the VIP room, I took a few deep breaths. One slip and Park Yuyoung would end up with someone else. I had to prove myself.
I checked the time. Iseol had said to go in after about a minute.
Veteran Kim Ji-yeon? Or maybe the always-free Lee Yeondo? Either way, she’d be face-down. I wouldn’t know until it was over.
The thought should have made me calmer. Instead it made my stomach twist.
When I stepped in, the room looked exactly as I expected. One staff member was already on the table—completely naked, face pressed to the cushion. Her side-boob was fully exposed, and her round, firm ass glowed under the soft lighting.
I walked over slowly, trying to look casual.
“I’ll apply the oil.”
The bottle in my hand made my eyes drift straight to her back and hips. Those long, smooth legs. The skin looked so soft it would probably change shape under my hands.
I poured the oil and started massaging.
“Mmm…”
The moment my palms touched her skin, it shivered. I found every red spot I needed to work and attacked them with slow, deliberate strokes. Her back kept breathing hot air against the table. She was melting under my touch.
No pink or blue spots visible. Interesting.
‘Who the hell is this? She’s got the body and skin of a goddess, and the staff here are all in plain black. How is anyone supposed to know?’
I worked the side of her chest deeper, the way I’d been taught. This wasn’t just massage anymore—it was full-on teasing the soft inner curves with oil-slick fingers. I brushed from her chest down toward the table, then back up, repeating until my hands were practically inside her.
It was obscene. The same way you’d handle bare breasts without a towel.
After the rear massage—exactly what Wonjae had requested—I stepped back.
“Thank you for your time.”
No reply. Her arms were limp, dangling like she’d been drained. Maybe she was satisfied. Or maybe not. Either way, my body still felt warm and relaxed. That was all that mattered.
I greeted everyone and left the room.
Everything was ready for Park Yuyoung.
‘Wonder who she is.’
I wanted her name. Or maybe I’d just hunt down every single staff member one by one until I’d seen every secret inch of that smooth skin. The thought made me smile all on my own.
When I stepped back into the hallway, Shin Iseol was gone. Another staff member was on duty.
“Shin Iseol… I mean, Manager Shin—Iseol where is she?”
“She asked someone else to cover for her for a bit. Didn’t say where she was going. She’s probably still in the shop. Taking a quick break or something. Need anything?”
“No… just checking for the client later.”
“Then she probably already sent the message. Don’t worry.”
“Yeah… thanks.”
So it was Shin Iseol after all. Huh. She had a killer body—those legs and that ass were something else. I couldn’t stop staring at her retreating figure.
Back in the staff lounge, no one was there. It was the usual time. I leaned against the wall, head tilted in confusion, when I heard giggles and the door opening. Shin Iseol and another staff member walked in, already changed.
“Unnie! This is Junhyun-ssi. The one who said he’d put his hand in my coffee.”
“Really? Junhyun-ssi did that?”
“Uh-huh. He’s so creepy.”
“Totally funny? Junhyun-ssi has a surprising sense of humor.”
“Ah, you don’t know because you’re not close. He really did grab and rub—”
“Anyway, Director just asked me about…”
The conversation cut off. She wasn’t the one who’d just come back from a massage. She’d been sitting here gossiping the whole time.
Lee Yeondo?
“Manager.”
“Oh? What’s up? Calling me manager now?”
“Are you saying Lee Yeondo’s in a massage right now?”
“Probably… why?”
Shin Iseol’s sharp eyes locked onto mine.
“You got a thing for Lee Yeondo?”
“No. I just got some education earlier and was curious.”
“Hmm.”
Not Lee Yeondo either?
Yeah… even if I only saw her in that black T-shirt, the girl’s chest was tiny. The side-boob on the table wasn’t A-cup by a long shot. Of course, I hadn’t actually measured anything. I didn’t even know the difference between cups properly, and I’d never touched an A-cup in my life.
What I did know for sure was that the skin on the table had been whiter and tighter than Kim Seoa’s. I wondered what that secret would feel like during sex. The thought made my collection list grow even longer.
Who the hell was she?
“Ah, time’s up. I’m heading out, unnie. Mr. Kang Junhyun, please head straight to the VIP room. Park Yuyoung already went to prepare.”
I nodded and walked toward the corridor. Even after practicing, my hands were shaking. First client. I had to focus on Park Yuyoung now.
Just then Lee Yeondo walked out in her uniform. Our eyes met. She looked like she’d done something wrong, dropped her gaze, and walked past me, whispering.
“H-hello…”
“?”
I watched her retreating back, puzzled. Whatever was bothering her, it had nothing to do with me.
With that, the mystery of the owner of that soft body had sunk even deeper into the unknown.
---
The scene felt different now—like the whole world had shifted because of something I couldn’t quite name yet. But I pushed the thought aside. Today I had work to do. And Park Yuyoung’s full-body treatment was about to begin.
