The World’s Greatest Sex Friend
“……Whoa.”
Saturday morning. Upon arriving at the address I’d been given, I stood there with a stiff face, letting out a quiet exclamation to myself. The moment I stepped inside, the scent of a diffuser wrapped around the tip of my nose. Soft, barely audible music drifted from the ceiling speakers, the kind that required intense focus to even register. Subtle indirect lighting and a gentle stream of natural light filled the space.
‘...Do they train the Survey Corps at this Pilates studio?’
When people think of Pilates, they usually imagine simple bodyweight exercises, but this place was equipped with bizarre-looking apparatuses installed along the walls. Even though I’d recently started going to the gym, I couldn’t even begin to guess how to use those strange contraptions. Beyond that, there was a lounge area near the entrance with incredibly comfortable-looking sofas and a table for tea. In the corner, there was even a spot with full-length mirrors and warm, orange mood lighting, with a sign clearly marked: <Post-Workout Photo Zone>.
Gulp.
‘Everything here looks expensive at a glance...’
There was a reason the land prices were so high. The quality and detail were meticulously maintained in every corner. Even the reception desk that greeted me was made entirely of marble. From the moment you walked in, the keywords beauty, luxury, and rich were plastered everywhere. This wasn’t just a place to exercise; it was selling a specific mood along with the service. It was a place that sold the image of being successful.
Furthermore, I was a man who didn’t fit in here at all, so the receptionist stopped me the moment I stepped inside. But when I mentioned the director’s name and said we were acquaintances, the staff member let out a drawn-out “Ah~” and, as if she’d been tipped off, her expression shifted instantly into a bright smile before she ushered me in. I had made it through the entrance unscathed, but—
‘……………What am I doing in a place like this?’
This was an incredibly uncomfortable place for a man to be. My awe was short-lived; standing alone in the center of the Pilates studio, I felt the back of my neck grow hot. Everyone here was a woman. The lounge was dominated by women, and the people warming up were all women. They ranged from women in their 20s to those who looked to be in their 50s. And they all looked like women with a massive amount of money. The carats of the diamonds embedded in their earrings and rings were substantial, as if to prove their wealth.
The only saving grace was that they were all indifferent to me. It was a relief that they didn’t seem to care much about me, the only man present, perhaps viewing me as some sort of laborer here to help with chores—
“Ah, honey!”
Just then. Right on cue, Yeoeun emerged from a room marked <Director’s Office>. As soon as she saw me standing blankly in the middle of the room, she made eye contact and strode toward me. Only then did my anxiety dissipate. It was the relief of meeting the only familiar face in a classroom full of strangers at the start of a new semester. Thanks to her warm welcome, I let my guard down.
“Honey, what are you doing? You’re here, so why don’t you come inside?”
“Oh, well, you see...”
“Hmm, never mind. The class is starting soon. Go change your clothes. Hurry.”
“……………Huh?”
My relief evaporated in an instant. Sure, we’d exchanged some words about it at the bar. She’d said she would make me sweat, but I thought it was just a joke. ‘Wait... she wants me to take a class here?’ The mere thought was a terrifying hellscape. With this weak, noodle-like body of mine, in a place filled only with women, she wanted me to exercise?
“No, no! I think just observing is enough—”
“That’s enough out of you.”
“No, I’m not joking!”
“I am the law here. So go to the men’s locker room and get changed, quickly♥”
“Excuse me!? Director Joo!?”
No matter how much I protested, Yeoeun just laughed and pulled my arm. As if she had planned it all from the start, she threw me straight into the pit of hell.
“Huff, huff, huff!”
I had seen hell. I’d had a feeling it would be hell from the start, and there were no plot twists—it was exactly that.
At first, it wasn’t as burdensome as I’d expected. There were tights for men, and though the outfit was embarrassing to wear for the first time in my life, it seemed that men occasionally participated in the classes, so the women didn’t pay much attention. In that relaxed atmosphere, like a reserve forces training where no one cares about anyone else, I looked at the full-length glass in front of me and tried to focus on the details of my movements. It proceeded as gracefully as Swan Lake.
“Now, next is the Hanumanasana pose.”
Within ten minutes, the true colors of the class were revealed: forced, bizarre movements. ‘How am I supposed to do a circus move like that right off the bat!?’ Perhaps she’d mixed in yoga moves with the Pilates, but Yeoeun, who was acting as the instructor, demanded movements that were cruel to any organic human form. It was the kind of movement that required core strength and terrifying flexibility—the kind of picture you’d get if an octopus ruled the world and was training humans.
-...Ugh.
-Hmm, mm!
‘...Damn it!’
I tried to follow along as best I could, but since everyone else was doing it and I was the only one struggling, a burst of laughter erupted from the people around me. I thought I was following at least 80%, but to others, I must have looked like a complete mess.
“Phew, it seems our guest here for the one-day trial is having a hard time keeping up.”
Yeoeun, ever the prankster, wouldn’t miss an opportunity like this. Once the class was in full swing, she treated me as if she were seeing me for the first time, using a polite tone to fuss over me. As she walked toward me while wearing the class tights, looking like a teacher tending to a slow student, I shook my head with all my might. Such a beautiful instructor was taking such meticulous care of me, but right now, I hated that attention more than death.
“No, Director! You really don’t have to go out of your way to help me...!”
“Come on, anyone can do it once you digest the pain.”
“Th-th-the leg splits... this is really my absolute limit!”
“You can do more. I’ll press down for you, so let’s go down a bit further♡”
“Ugh!? Gyaaaaaaah!!! Teacher— no, Yeoeun, please stop!”
“Right now, I’m Instructor Joo Yeoeun♡”
-Puhahaha...!
-Kekekekekek...
Even though I spoke to her informally in the middle of it, Yeoeun didn’t let it slide. ...She was a clown. After saying she’d let me take a free trial of an expensive class, she treated me like a toy throughout the entire session. I was getting played, hard.
‘Huff, huff... I’m glad I started working out!’
The only comforting thing was that I had recently started exercising. If I hadn’t, I would have surely ended up face-down on the mat. It was easy to imagine a future where I couldn’t even keep up with half the pace and ended up rolling around pathetically. Because I’d built up some basic stamina lately, I managed to finish the full 50 minutes of the class.
“Whew, you followed along until the end, honey?”
“Haa, haa, haa...!”
“You didn’t even run away in the middle... that’s quite rare.”
After the class, we were alone in the Director’s Office. I gulped down the bottled water I’d taken from the office fridge, using our personal connection. Sitting in what looked like an expensive director’s chair, she covered her mouth and chuckled, praising me for lasting longer than she thought.
“So, how was it? Was my class fun?”
“...No, I thought I was going to die.”
“That’s how much healthier you’re getting♡ You sit in a chair all day, honey, so it’s a friend’s way of worrying about you, right?”
“You were just teasing me the whole time...?”
“I was giving you special attention, wasn’t I? Besides, I didn’t even charge you a one-day tuition fee.”
She took the empty water bottle from me and added, “You know, I’m a star instructor, so if you wanted a private PT session, the tuition would be incredibly expensive.”
...I didn’t even have to ask to know that was true. Her appearance alone proved it. Just like the environment here, if Yeoeun taught a class, it would come with the fantasy that ‘I could become like that too.’
‘Come to think of it, does she have fame to go along with running a studio of this size?’
I didn’t know much yet, so I filled in the blanks with my imagination. I’d heard she was active on social media, so she probably used that for promotion. Or, setting all that aside, it might just be a hobby for a wealthy young lady.
“Honey, more importantly, why do you think I invited you today?”
“...To play with me?”
“Yup, exactly that!”
Her bluntness, not even bothering to deny it. Her lips curled into a smile as if she’d just had fun treating me like a toy throughout the class.
“But you know, there’s one more very~ important reason.”
“Important reason?”
She smiled. Instead of giving me an answer right away, she stood up from her chair. By the way, perhaps because of the sweaty class, Yeoeun wasn’t wearing any makeup today. Even so, her skin was as pale as a pearl that had spent its life avoiding direct sunlight, and unlike me, who was drenched in sweat, she was only slightly glistening.
“I personally love the heat after a workout.”
“...Heat?”
“Ah~ this is the best moment. You’ve warmed up your body, and this moment when the faint scent of sweat rises... it’s the best.”
She gave a vague, non-committal answer and stepped away from the director’s table. She glided past me and stood with her back to the door of the office. Blocking the entrance, she looked down at me—drenched in sweat—with a seductive gaze. As if she couldn’t hold back any longer, she swept her eyes over me from head to toe.
“You’re in the most delicious state right now♥”
Click!
The office door locked. That short, sharp sound announced the reality of the situation. I’d been busy catching my breath after the chaotic class. I had wanted to wash this soaked body in the shower, but that metallic sound made my spine stiffen. No matter how much I struggled, Yeoeun approached me as if she’d already made up her mind. She was still in her stylish Pilates outfit: tights that reached her navel, a loose shirt revealing one shoulder, and a sports bra underneath.
She turned the chair toward the entrance, and before I could even pull it back, she pressed down hard on my shoulders and rested one knee on the chair.
Press!
She put her full weight into it. As she pressed firmly against my thigh, her face came right up to mine.
“Honey.”
Gulp!
I couldn’t move. It was just one woman. She was probably lighter than average, yet I couldn’t do anything but stare at her blankly. I looked up, expecting to hear what she had to say:
“Let’s finish what we couldn’t do before♥”
