Chapter 68: Gym (5)
The weight room.
If I were still in the military, this place probably would have been called the physical training room. It was filled with equipment that looked expensive enough to justify the membership fees.
Half of the machines were things I had no idea how to operate or what they were even for, while the other half had purposes and methods so clear a child could understand them.
If I had to categorize everything in here, I’d split them into two groups: equipment designed for the sole purpose of working out, and equipment designed to assist the user in doing so.
Standing in this forest of iron, I had to steady myself, my eyes darting around nervously.
Just what kind of exercises should I do, and for how long? Back when I was fencing, Mom used to plan out every single detail of my schedule, but now I had to do it myself.
It felt foreign. It wasn't exactly painful, but I felt... lost.
So, I looked at Kang Yu-min.
“…What should I do?”
Yu-min’s reaction was faint. She seemed to be in a daze before blinking as if my voice had finally snapped her back to reality.
“Um, well... didn't you have something in mind?”
“No. That’s why I’m asking.”
“In the past…”
“Mom always set the schedule for me. So…”
Yu-min barely managed to catch her breath and nodded.
“Then, do you want to just do what I tell you?”
A workout schedule from a total gym rat. I was a bit worried about whether I could keep up, but what I lacked wasn't stamina—it was muscular strength.
And considering that my strength was only "relatively" lacking, it shouldn't be a problem. I nodded, and Yu-min led the way.
“First… let’s start with dips.”
“Dips?”
“Yeah, this.”
The piece of equipment Yu-min led me to wasn't something I recognized immediately. It wasn't because it was complicated, but because it seemed to have several different functions.
“Go ahead and grab it. Hold it there… and feel like you’re lifting and lowering your body. Focus on your chest…”
Fortunately, I had a gym rat by my side. I faithfully followed her instructions and got onto the machine.
As I started the movement, I realized it was similar to an exercise I used to see the athletic kids doing back in school.
It felt… how should I put it?
“Oh… this is something.”
I could definitely feel the workout. Every time I went down and came back up, I felt my muscles stretching and pulling.
“…Do you want to add more weight?”
Yu-min’s reaction was a bit unsettling, but I simply nodded.
But weight? How was she going to do that?
I felt a sense of doubt but didn't ask. I flinched when Yu-min naturally stepped toward my waist.
“Uh, hey, wait?”
“Stay still… I’m putting on a weight belt.”
I mean, this was a bit embarrassing.
I was flustered but didn't stop her. Feeling her movements near my pants, I glanced around.
Fortunately, the weight zone was large, and although people didn't seem to be paying us any mind, it wouldn't be strange if someone looked our way at any moment.
I grew tense and my shoulders stiffened involuntarily. Yu-min fastened something like a strap around my waist.
As she did, she rubbed her cheek against my crotch, her breath coming out in shallow, hazy puffs.
At least her objective was clear—even if it was laced with other intentions.
I looked down at the belt around my waist and the iron plate hanging from the end of it.
It was a massive, heavy-looking disc. Perhaps because I had already experienced my 10x Stamina on the stair climber, I could already feel its weight.
“Oh…”
“Now, try it.”
Yu-min’s breathing was strangely heavy, and her face was flushed. Before I could process the tone hidden deep in her voice, I continued the exercise.
Down, and up. I relied solely on the strength of my arms. I didn't feel like my muscular strength had increased, but I didn't feel the usual exhaustion that comes when you hit your limit.
My arms didn't ache, and my muscles didn't feel fatigued.
It was unnatural. Perhaps because I didn't have the muscular strength to match this level of stamina, the fact that I felt almost no exhaustion despite my lack of strength felt awkward.
So, when I squeezed out every bit of effort to move, there was a corresponding load placed on my muscles.
However, my joints and muscles were sturdy beyond common sense. Even though this was clearly an exercise beyond my normal capacity, I was able to perform it.
I couldn't help the sweat that poured off me like rain, though. Feeling the sweat dripping from my entire body, I let out a hollow laugh.
Something was strange. Sweat was pouring, and my arms were trembling slightly, but the load on my body felt almost non-existent—even though it clearly existed.
“…Let’s take turns.”
As I repeated the exercise, a voice suddenly reached me. I stopped mid-motion as if snapping out of a trance, and I heard Yu-min gulp.
“Oh, right. We should.”
Since my body wasn't tired, it was strangely fun.
It was fun, and because I wasn't exhausted, I became absorbed in it.
And because I was absorbed, I stopped paying attention to my surroundings. I looked at the sweat pooled on the floor and gasped in spite of myself.
“…This is insane. 10x Stamina.”
If I were a marathon runner, wouldn't I be some kind of national-level powerhouse?
I let out a low groan as I seriously considered the possibility. I stood up and was looking around when she spoke.
“Don’t wipe it.”
“Huh?”
“Don’t wipe the sweat.”
Wait, does she want to work out that badly?
That’s what I thought at first, but there was no way. This was something else. Yu-min was currently…
She was turned on. And she wasn't just excited; she was several times hornier than I had ever imagined or assumed.
“You crazy bitch…”
She didn't even argue with my muttered insult. Just seeing her climb onto the machine with her ragged breathing was enough to tell.
Come to think of it, it wasn't that strange. I hadn't known about Yu-min’s fetishes until now, and I had never given her the chance to explore them before.
It meant it wasn't strange at all for Yu-min to feel an intense sexual desire for my sweat and body odor. I swallowed hard and stared blankly as Yu-min began her set on the machine.
With a flushed face, she moved up and down. As she moved incessantly, sweat rolled down the lines of her muscles, and her exposed midriff was slick with it.
One would think my sweat on the machine would be bothersome or gross, but Yu-min didn't show even a hint of such a feeling.
If anything, she moved even more vigorously, as if my sweat were some kind of lubricant.
“Hey, hey… are you okay? Your breathing…”
“I’m… fine.”
Yu-min panted, her voice bordering on a moan. I looked around again, relieved that no one was staring at me or Yu-min yet.
Maybe it was because this was an expensive place frequented by the wealthy, but people seemed largely uninterested in others.
It was a huge relief. Though there was no guarantee it would stay that way.
“Uh, Yu-min…?”
“Just… a moment…”
Yu-min stopped, sitting on the machine while breathing heavily. Her eyelashes fluttered over her downcast eyes as she nodded.
“Give me… the towel.”
“Oh, okay.”
“Next… let’s go.”
Did she always work out like this? Maybe, but I couldn't shake the feeling that there was more to it.
I followed Yu-min from machine to machine.
And in the process, I had to endure Yu-min’s inappropriate touching.
For example, it went something like this:
When I grabbed the bar for pull-ups and moved up and down, Yu-min, who had been watching intently, would approach and bury her face near my crotch under the pretext of adjusting the weight belt.
When I took my position for the bench press, she would make subtle physical contact under the guise of spotting me.
I wondered what she’d do if I actually got hurt, but fortunately, that didn't happen. Perhaps it was because Yu-min was already so experienced with working out.
Or maybe her arousal was giving her strength.
To make matters worse, since my own body felt no physical exhaustion, there was no risk of these skin-to-skin contacts leading to an accident.
“Hey, hey! What if someone sees…!”
“…Let them look.”
“You’re crazy… No, why are you being like this all of a sudden?”
“What do you mean 'all of a sudden'? I told you I like you.”
Yu-min even turned the tables on me when I tried to question her.
“I get horny just looking at you. And when you… show me stuff like that, do you think I can stay sane?”
Seeing Yu-min practically threatening me with her distorted expression made me lose my nerve. I instinctively hunched my shoulders, and Yu-min lightly placed a hand on them.
“Shoulders back. You’ll get hurt.”
“Yes, ma'am.”
I wondered if coming to the gym together had been a mistake after all.
“Lift.”
On the other hand, a part of me secretly thought this wasn't so bad. Yu-min might be a loser, but she was actually quite cool-looking. Her forceful side suited her surprisingly well.
Most importantly, even though she was excited, she wasn't neglecting her role as my spotter, so I was getting a genuinely good workout.
And the same went for Yu-min.
“Help me. Hold this.”
We took turns on each machine, using the other person’s set as our rest period.
Inevitably, Yu-min spotted me and I spotted her, which made physical contact unavoidable.
“Ngh, ah, haaa.”
Even that process seemed to fuel Yu-min’s arousal, as her crotch was gradually becoming stained with unmistakable body fluids.
It was a scene so erotic it made me wonder if she had skipped underwear just for this.
Her sweat-soaked skin glistened under the fluorescent lights, and her damp hair clung to her skin, creating a visceral, tacky texture.
Forgetting the fact that we were siblings, we worked out while staring intently at each other’s bodies.
From strength training to core exercises. We took turns harmoniously.
Of course, "harmonious" didn't exactly describe the typical sibling dynamic, but who was there to say anything?
Our relationship as siblings had been twisted for a long time now, and a literal transcendent being was backing us up.
“Hey, uh… it’s really showing. Right there.”
When I pointed toward Yu-min’s crotch, which was emphasized by her lack of underwear, she let out a ragged breath.
“I know.”
Even Yu-min, who was usually a loser and easily swayed by me, had built up a massive amount of arousal through the continuous exercise.
Setting the barbell down and exhaling sharply, it seemed almost inevitable when Yu-min grabbed my wrist.
“…Follow me.”
I followed Yu-min toward the restroom.
