The Scale's Scream and Steamy Stretches
The day after our all-night gaming marathon with that bizarre exercise session, my morning began with a scream echoing from the living room.
"Eek!"
That shriek jolted me awake, shaking my sleeping body. "Wh-what is it…?" I wiped the drool from my mouth and checked the time. 5:50 AM. It wasn't even 6 yet, but the door was already open, and the only people in this bunker were me and Yoon Yerin—so it had to be her scream.
"I should go check right away." If she was this startled first thing in the morning, it wasn't something trivial. I hurried toward the living room.
"Y-Yoon Yerin-ssi?"
When I finally emerged into the living room, I spotted her right nearby. Yoon Yerin was slumped on the floor, trembling as she stared at something.
"What happened? This early in the morning…."
Zzap—.
"Eek, wh-why are you glaring at me all of a sudden…."
"…This is all because of you, Lee So-yul-ssi."
"Huh? I-I didn't do anything…."
What the hell? Did something go wrong because of me? I had no clue what was happening, but since it seemed tied to me somehow, I racked my brain reviewing the past few days. Day one: cooked meals, physical exam, bath where I jerked her off…. Yesterday: came on my ass, then gamed together and she finished on my belly too….
…Yeah, it's kinda weird when I list it out like that.
But nothing felt like a real mistake. Sure enough, after sitting there for a while, Yoon Yerin apologized to me.
"…Sorry. You didn't do anything wrong at all, really."
"It's okay. So what happened…?"
When no answer came right away, my gaze naturally drifted downward. There sat a scale, all by its lonesome.
"A scale? Did you…."
"N-no, it's not that! I just checked it for the first time in ages, so don't misunderstand."
"…I didn't even say anything."
Whatever the case, the situation screamed one thing….
She weighed herself this morning, and the number was too high.
Women really do obsess over their weight, huh. With this body, starving was my daily routine until recently, so I'd never even imagined stressing over it. Still, that seemed to be the conclusion.
"…Honestly, yeah, I've gained weight. I've been eating so much of the food you've been cooking lately that this happened…."
Yoon Yerin finally confessed the truth about it all.
"I ended up snapping at you without thinking. Sorry."
"I-it's fine. That can happen. But weight fluctuates up and down anyway, right? No need to worry too much."
That earned me another sharp glare.
"…You know, you have such a pretty figure when I look at you."
"R-really?"
"No flab anywhere, skin all soft and supple…. Kinda makes me jealous."
"Y-Yoon Yerin-ssi is so beautiful already, you don't need to…."
Even as she teased playfully, Yoon Yerin's expression suddenly darkened.
"…And I have a reason why I can't afford to gain weight."
"A reason you can't gain weight?"
"I'll tell you later."
I had zero guesses about that reason. Maybe it had something to do with me? But her face was filled with such deep worry that it didn't seem likely.
"…If the problem is extra weight, why not just exercise?"
"Exercise?"
"Yeah, I think you mentioned a gym facility on the first day."
Yoon Yerin's eyes blinked at the mention of the gym.
"That's true, but I've never actually used it…."
"Huh, why not? It looked huge and nice."
"To be precise, I couldn't figure it out from the videos alone."
"So it's just been sitting unused?"
She nodded at that.
"…Want me to show you how?"
For some reason, the words slipped out offering to teach her.
"…You?"
She stared at me like she couldn't believe it.
"Yeah, I know a bit about how to use them."
It wasn't a lie. Sure, I couldn't afford a gym membership, but I went to the park often enough to learn the basics on the public equipment.
"So if you want to build stamina, I can—hngh!"
Poke.
Poke.
"W-wait a sec…."
Squish.
"Wh-why are you poking my side all of a sudden…."
"…So you're saying this soft body of yours is gonna teach me how to work out?"
But she ignored me completely.
"I-I'm just out of practice right now, but I do exercise, okay!?"
"…I can't believe it at all. Lifting weights with such a frail, delicate body."
Stroke.
"Still, your figure is nice, so you must have some talent."
"…People usually don't say that while staring at my chest, you know?"
Then Yoon Yerin grabbed my hand lightly, like she'd made up her mind.
"Alright, teach me then? I'll learn seriously."
And just like that, our morning routine turned into personal training.
*
We headed to the gym via elevator, getting off on the second floor—the same level as the game room yesterday. Apparently the gym was right there too.
"Gym's on the second floor too?"
"Yeah, right next door."
After passing the game rooms, the fitness equipment came into view.
"Whoa…."
Up close, the machines were insane. I'd figured the gym would be top-notch since everything else here was, but this was next level.
It's like they wallpapered the place with money.
Multi-function machines for all kinds of exercises, popular models that always had lines at public gyms—everything was brand new and state-of-the-art.
"This is amazing."
"What first?"
"Ah, warm-ups to start…."
I set down the water bottle I'd brought and suggested we loosen up together.
"Can you show me the proper warm-up form from the beginning? Might as well learn it right."
"Sure."
She agreed to start from scratch, just like that.
"Injury prevention is key, so let's loosen the shoulder joints first."
"Joints…."
"Extend one arm across your body and press with the other."
"That's tricky."
"Already? It's just warm-ups."
"Looks like I need a demo first. Can you show me up close?"
"Got it."
I faced her and demonstrated.
"Arms out like this, slowly without forcing it too far…."
"Hard to get just from watching. Mind if I feel where the stretch is?"
"Ah, sure, go ahead…."
Poke.
"Ahh."
"Here?"
Poke.
"Ow, hold on…."
"Or maybe here."
She poked my side boob, but her serious expression kept me from protesting.
"Kinda confusing, but I think I get it a little."
"…Next, hip joints."
I pushed aside the weird feeling and sat on the floor.
"Spread your legs out, then lean your torso forward."
"Need a closer look for this one too. How exactly?"
"J-just do it like I did."
"Like this?"
…At this point, it felt deliberate.
"F-first, spread your legs like this."
As I parted my legs, Yoon Yerin stared intently.
"…Then hands on the floor, push forward. Done."
"Like this?"
"No, not…."
"Gotta see this pose again too. Redo the leg spread?"
"……."
I went back and spread my legs again.
"Just this wide, then…."
"Hold on, stay like that. I wanna check exactly how wide."
"Th-this pose?"
She crouched right in front of me to inspect.
"Yeah, hurry."
"I-it feels too close…."
"Mind if I touch?"
"M-my thighs?"
My legs flinched at the sudden question.
"Yeah, you're in shorts anyway, and touching will make it clearer."
"Wai—."
Stroke.
"Eep…."
"Outer thigh feels normal. Gotta check inside."
"I-I didn't say you could touch…."
Prod.
"Ahh…."
"This side feels a bit different."
"Ngh…."
What the—? She'd groped me sneakily before, but this was blatant….
…No way.
Is it because of what I said yesterday? No, even so, this is too much….
"……."
Not content with kneading my thighs, Yoon Yerin was fiddling with my pussy now.
"Um…."
"Definitely more moisture inside. Sweat, right?"
"Eep, stop…."
"…You know what they say, though?"
She even started teasing me outright.
"Some people get horny thoughts during workouts, apparently."
Squelch.
"Heard if the thoughts are lewd enough, pussy juice leaks out even mid-exercise."
"Hah, th-that's…."
"What do you do if you meet someone like that? Run away, probably?"
"……."
Up to then, I figured it'd devolve into our usual fuzzy flow. So I spread my legs wider to hide it.
Not because her fingers felt good.
Just to satisfy her quicker. That's all.
But then—
Drip.
"Sorry. No more teasing."
She pulled her hand away abruptly.
"Eh, uh…."
"I changed into workout clothes to teach you, tied my hair up—you looked so cute."
"Cu…."
"Made me wanna play a little."
Cute, huh. Comments on my figure or soft tits never fazed me.
But cute? That hit different, made my chest feel weird.
"I'll focus now, so show me again?"
Even as I processed her words, her fingers caught my eye.
"……."
Glistening from wriggling inside me moments ago. Maybe I was losing it, but….
My gaze kept drifting there.
Wiggle.
"…Next, let's learn squats."
