Chapter 65: Gym (2)
Chapter 65: Gym (2)
The gym’s glass door slid open as Kang Yu-min swiped her card. I stared blankly at the opening entrance.
“Wait, did you say you’ve never been to a gym before?”
“Never.”
“Then I’ll explain everything once we’re inside.”
It felt awkward seeing Kang Yu-min act like a proper older sister for once, but I didn’t feel like teasing her in this situation.
For one, it really was my first time, and it was in my nature to feel intimidated by facilities like this. I was terrified of making a mistake and looking like a total idiot—and in a place like this, that kind of embarrassment felt like a life-or-death matter.
Who knew? Maybe the people waiting inside would toss me out the window the moment I messed up.
So, I simply nodded and followed my excellent guide inside.
Someone was there to greet us as if they’d been waiting. A receptionist, I assumed. Kang Yu-min handled the staff with the "cool" persona she usually put on for the public (though she was actually a total dork) and then gestured toward me with her chin.
“Sit here for a second.”
“Yes, ma’am.”
“And… where was it… Ah, here. Fill this out.”
She approached me as I sat obediently and handed me a set of documents.
I wasn’t sure if gyms usually gave these out, but the form asked for my personal information, the purpose of using the facility (optional), the duration of membership, and even whether I wanted PT.
Then again, it made sense.
You needed a key card just to get through the door, and the interior was packed with equipment that looked incredibly expensive. Considering the gym was located on the top floor of a department store, tight security felt like a necessity rather than an option.
I filled out the form without hesitation. By the time I finished, Kang Yu-min had changed and reappeared in front of me.
Her outfit was quintessentially Yu-min.
She wore something closer to a sports bra that left her navel completely exposed, paired with skin-tight leggings. It was a brazen outfit that prioritized mobility over everything else, including modesty. Personally, I found it quite provocative.
I figured other men probably felt the same, but Yu-min, in her typical dorky fashion, didn't seem to care about the stares.
Or maybe she just hadn't noticed.
“Done?”
She walked over and asked. I double-checked the form, not wanting to give her a reason to mock me.
“Yeah, I think so.”
“‘You think so’? Give it here.”
Yu-min took the papers and read through them meticulously, her small face almost entirely hidden behind the documents.
“Hey, you checked the one-week option.”
“Yeah, that’s right. I put one week.”
“Why? Do a longer one. It’s cheaper that way.”
“I mean… it’s not like I’ve officially decided to keep coming here…”
“Why not?”
Yu-min lowered the papers and stared at me. Her eyes, shimmering with a faint sense of betrayal, conveyed several meanings at once.
“Let’s work out together, okay? I’ll teach you everything.”
“Umm…”
“…A-and, you can only use the private shower booths if you sign up for a year…”
Ah, I see. I gave her a look of disbelief as I realized her true intention. Yu-min pouted and smacked my arm with a loud thwack.
“Ow.”
“Fix it. Now.”
“You pervert.”
“W-what?!”
She smacked my arm again, and I eventually gave in to her demands.
I crossed out the circle for one week and circled the one-year option instead.
“Wait, there’s no price listed.”
“Yeah, I noticed that.”
“How much is it?”
“817,500 won for a year.”
What?
My eyes trembled as I looked at her, but she avoided my gaze.
I knew it would be expensive, but this exceeded my expectations.
“How much does it usually cost…?”
“It varies by gym.”
“Okay, then how much was the place you used to go to?”
“…520,000 won a year for new members, and 300,000 for renewals…”
Holy crap.
My jaw dropped at the price. Yu-min’s face turned even redder as she struggled to look away.
She looked like a child afraid of being scolded, but I couldn't let my heart soften. As her brother, I had to give her a piece of my mind.
“Didn’t you say you were going to be careful about wasting money?”
“I did. I did, but…”
“But?”
“I’m sorry…”
Yu-min’s shoulders slumped in defeat. I sighed and looked at the form. The staff member acting as our guide was watching us, and I couldn't exactly storm out now.
Besides, it was true that I needed an excuse to give to our eldest sister.
…Fine. What’s the point of saving money if I don’t use it? I can make it back after a few games anyway.
I pulled out my smartphone to check my funds and opened my banking app.
[General Bank Account]
[51,617,517 KRW]
Yeah, I had plenty.
The fact that I was dropping nearly a million won on a gym membership still bothered me, but I eventually accepted it.
“Ah, I’ve processed your registration. Shall I show you around the facilities?”
When I submitted the completed form, the staff member smiled brightly, looking relieved. Beside me, Yu-min shook her head with a tension that only I could detect.
If she weren't so pretty, she would have looked like a total dork, but with her looks, it just came across as a "cool" gesture.
“I’ll do it.”
“Ah, alright. Have a wonderful time.”
The smiling staff member handed over the card key. I tucked it into my wallet and started walking with Yu-min.
As we walked, it became clear that the gym was worth the money.
I’d expected it to be pricey since the description mentioned a swimming pool and a golf range, but seeing it in person was something else entirely.
It just looked expensive.
Occupying about two full floors of the massive department store, its scale and size defied common sense.
“Do you swim?”
“Sometimes.”
“Right, the one you wore back then was a competitive swimsuit. Do you actually swim in that?”
“Uh, yeah. Why…?”
Yu-min asked with a nervous look. Instead of answering, I just nodded and moved on.
“This is the private shower booth I used today… Do you want to go change? Or you can just look around for today.”
“No, since I’m here, I might as well get some exercise in.”
“Okay, then. I’ll be waiting.”
I wondered if she’d ask to go in together, but she didn’t.
It was more like there was no need to ask, which made sense.
I wasn't sure what she meant by "private shower booth" at first, but I soon understood.
The shower booth doubled as a private locker and changing room.
Yu-min’s street clothes were hanging inside, and the shower area was bone-dry, as if it hadn't been used yet.
It even had a lock. Seeing a shower room that could likely only be opened with Yu-min’s card key, her goal was obvious.
I decided to just go with it. If she liked me that much, it wasn't something I couldn't handle. In fact, seeing her hold back that much because she liked me was almost endearing.
I quietly changed into the workout clothes I’d bought today.
The tight short-sleeved shirt clung to my skin, and the loose, drawstring shorts settled comfortably on my legs. The new white shoes felt snug and comfortable, and the breathable socks had that distinct factory smell of new clothes.
Standing there, I could finally understand why guys who make a big deal about going to the gym get so excited after buying gear.
It felt… satisfying to spend the money.
“See? I told you this place was great.”
I wanted to take back my thoughts the moment I saw Yu-min gloating, but there was no undoing what was done. I simply ignored her.
“So, what should I start with?”
“Stretching first, obviously.”
She was right. I nodded in agreement and followed her into the dedicated stretching room.
“…Stretching, huh.”
It had been a while. They made us stretch in the military, but that never really felt like proper exercise stretching. By the time you became a sergeant, you usually just ignored it anyway.
“What should I do?”
“You can start from the top and work your way down, or start from the bottom and work up.”
“Ah, so you’re the type who doesn’t care about the order?”
“I guess? Though I always start with my legs.”
Yu-min lifted her leg slightly. I glanced at her thighs, wrapped tightly in leggings, and nodded.
After all, Yu-min had the thickest thighs out of the three sisters.
That was why, whenever we did it, the pressure and resistance as she pushed back felt so good. It made me want to keep going, even though it usually finished me off quickly…
“…What’s with that look?”
“What look?”
“You have a dirty look on your face.”
“I do not. Let’s just stretch. I need to work out.”
Yu-min gave me a suspicious look but began her stretches anyway, allowing me to finish my train of thought.
As expected of a former star soccer prospect, the way her muscles moved during her stretches was…
Incredibly captivating.
“…Wow, you’re flexible.”
I was genuinely shocked when she did a full split, her crotch touching the floor.
“Whatever. You do it too.”
Yu-min acted like my reaction was an exaggeration, but she was clearly pleased. I followed her instructions and stretched beside her.
I followed what I remembered and the "backseat coaching" she gave me, being as thorough as possible.
After all, every workout starts with stretching.
I thought I’d finished loosening up my body, but…
“Huh? Done already?”
“Yeah. Why? I think I did everything.”
“You didn’t loosen your hip joints, and your thoracic spine is still stiff…”
Oh, really? I figured there were just stretches I didn't know.
“This won’t do. Lie down.”
“For what?”
“Just lie down. Now.”
Yu-min seemed dissatisfied. I had no choice but to lie down as she ordered.
“I’ll loosen them up for you, so just stay still.”
She pressed herself against me, initiating a very suggestive level of physical contact.
She grabbed my legs and pressed her body down, her exposed midriff rubbing against me.
“It doesn’t hurt, right? Tell me if it does.”
She pressed her breasts against my back, letting out moans that sounded a bit too erotic.
I wasn't entirely sure what she was doing as our bodies tangled together—twisting my waist or forcing my knees to loosen—but I could feel the blood rushing to a certain area.
“Ah.”
Naturally, the physical change became prominent. And that change was laid bare when Yu-min sat facing me, pulling my legs apart into a split.
Yu-min’s face flushed deep red. She started to turn her head away but stopped, staring intently at my crotch.
“Pervert.”
“…Who told you to… make it stand up? Seriously.”
Even as she grumbled, she didn't look away.
I had a feeling I’d be doing it here at the gym, too.
Well, it was bound to happen.
