Chapter 108

I hesitated for a moment at the trainer's words before nodding. I didn't have any clothes to change into, and my body was already hot, so I thought that would be better.

The trainer immediately approaches from behind, stands behind her, and grabs her hips. Her body is so slender that if he just slightly turns his large hand around, it seems like the tips of her fingers will touch.

"Okay then, now push your butt back as far as you can."

"Ugh…."

I was doing exactly as the trainer told me to do, and since he was right behind me, I could feel something hot touching my butt. I was startled and about to fall, but I couldn't fall because of the two hands that were holding on responsibly, either to keep my leggings from falling down or to correct my posture. I slowly straightened my legs and stood up, moving my waist as the trainer moved his hands, holding the dumbbells with both hands.

"This exercise stimulates the lower and upper body. When going up, rather than being conscious of the hip joint, you should stand up using the front thigh muscles and calf muscles, and from the middle, you should stand up using the buttocks and back muscles. Let's do it slowly while being conscious of it once."

"Yes, yes…."

"When going down, do the opposite of when you went up. Oh, don't let go of the dumbbells, but lower them just until they're slightly off the floor, then lift them back up."

I move slowly as the trainer says. The dumbbells aren't that heavy, so it doesn't take much strength, but every time I lower my body, the hot heat I feel against my butt makes me flinch and startle.

It's really huge. Considering the reach, it seems to be positioned so that it faces the right leg, but it feels hot, about half the length of the trainer's thigh. How big is this thing?

"Um…don't worry too much about it."

"Ah, um, yes…."

Because I kept trembling, the trainer spoke in an awkward voice and continued to say, "One, two," again. However, every time my butt fell back, or I tried to fall forward in surprise, the trainer held me tightly with both hands and kept me close, so I couldn't help but be nervous. Maybe it was because the dumbbells were light, but at some point I forgot the number of repetitions and started repeating the movement mechanically, to the point where I could feel the hot heat even when my butt wasn't touching them, as if a trace of it was left, and when it did touch them, I didn't flinch at all but rather just kept them gently close to me and felt the heat, and only then did the trainer let go of my waist.

"Haaah…."

"Hmm… I guess you have better strength than I thought. I increased the number of repetitions, but it doesn't seem like you're having a hard time. Was it easy?"

"Oh, yes… a little."

As I said, the dumbbells were definitely a little light… Even after the trainer's hands were off, I could still feel the heat on my butt, so I pulled up my leggings a little to try to wash it away.

The waist fits perfectly… but how big must the butt be for it to come off just by bending over?

It's really hard to get dressed.

"Then next time I'll try rabbit jumping."

"Is it really a rabbit jump?"

"It's a slightly modified exercise. It's an exercise that straightens and corrects the legs. When people say rabbit jumping, people usually have a preconceived notion that it's not a very effective exercise, but it's a common exercise, so it's considered that way, and it's actually more effective than you might think. First, let's take a short break."

"yes."

The trainer immediately put the dumbbells back in their place, sat down on the sit-up table, and patted the side. Now that I think about it, is that really a piece of exercise equipment? No matter how much I think about it, it seems like they're just using it as a chair.

While I was sitting next to him and taking a short break, I saw the trainer take a deep breath. He must have sensed my gaze as he looked in my direction, then avoided eye contact, rolled his eyes to the side, and smiled.

"Umm… I told you not to worry about it, but you still worry about it, don't you?"

"Huh? What is it…?"

"Hmm, I'm a bit… big. I mentioned this before, right? I'm not good at making girlfriends."

Only then did I realize what he was talking about, so I averted my gaze. It was huge… It was definitely huge. I was curious, but also a little scared.

"You seem to be a bit concerned, but don't worry. I'm a professional, and this kind of thing happens more than once or twice as a personal trainer. Honestly... I can't help but react because you're so pretty and have such an attractive body that I suggested that you come to the gym for free. Can you understand that?"

"Yes, that… I understand."

"Wow, thank goodness… I'm not doing this because I really want to. In fact, women may not understand this, but men are designed to be visually and tactilely aroused… Oh, it's not that I get aroused just because of it. I can't help but react. It's a physiological problem. And other male trainers don't notice it when this happens… But in my case, it's a bit much, right?"

The voice seemed to be saying it with genuine concern, but for some reason it sounded more like bragging or showing off than embarrassed.

"Ah, yes… Yeah, I guess so."

"If you look at it too, you have a really pretty butt, but since it's big, like before, things like that happen, right? Your breasts are also big, so you feel uncomfortable, right? You can think of it as the same thing. Since it's so big, the discomfort that wouldn't normally exist is a bit big... That much?"

"…yes."

I feel like it's a bit like sexual harassment, but I don't think so... It's ambiguous.

If you think about it, the content is very sexual, but since it is only talked about while exercising, it sounds like it is something you say because you are really uncomfortable.

"Actually, this may be really bothering you right now, but it's just uncomfortable for me. It's so hard to date a girlfriend... People usually think that it's easier to date women when you grow up, but it's the opposite."

"is it so?"

I'm curious about this. Isn't bigger always better?

The trainer smiled when I showed interest and continued talking.

"Of course. In fact, since both of us are adults, this is something we can talk about, but they say that compatibility is important when having sex, right? If compatibility is good, you can really fall in love with your one-night stand partner. But when this thing is as big as mine, compatibility is really hard to get right. Originally, people of average size could feel it to some extent with both small and large women, but for me, the premise is whether I can put it in."

It's… convincing. Well, if it's that big, it would be a problem to put it in. But I thought that if I pushed myself, it would somehow fit in… Is it that serious? A woman's body can't be that inelastic.

"So, I've never moved freely during sex... But when they find out that it's big, women try to sleep with it at least once, probably out of curiosity. But the problem is, when they try to sleep with it, they give up before they can even put it in half?"

"Is that it?"

Even though we were talking quietly, when I showed my reaction again, he snickered. It seemed like he really enjoyed talking to me.

"But now that I've gained some experience, I've come to know what kind of woman she is. First of all, if her butt is big and flexible, most of the time she goes all the way in. But this is also a problem... Once these kinds of women fuck me, they can't forget me. Some women just cry... That's also because I'm a perfect match for these kinds of women. And since there aren't many men with this kind of size, it's hard for them to be satisfied even if they meet other men... Right?"

I nodded without realizing it as I listened quietly. Compatibility… Certainly, after having sex with the old man, I changed to the point where I didn't even know why I was acting like this.

But there's something I'm a little mistaken about. It's not that just because a butt is big and flexible, it's necessarily big. Rather, there are men who are just the right shape and length, and I like those men more than just big ones. Actually, if you think about it, David is also cute, but I fell for him more...

…I fell for you. Why on earth am I having such ridiculous and embarrassing thoughts?

Rather, it's probably that the old man has fallen for me.

As I sat there thinking, the trainer seemed to have calmed down a bit and got up from his seat. But only then did I realize that the conversation just now was a bit strange. Isn't that something a trainer should say to a member at a gym…? Or not? Is that what men and women of this age usually talk about?

I don't know. How can I know the conversation between a man and a woman who give off such a popular vibe in an otaku's life?

"Okay, then squat down right now. You know the rabbit jump pose, right?"

Although I was a little confused, I did as the trainer told me to do and got into the next exercise position. I squatted down with my legs slightly apart, my hands on my thighs, and my chest touching my knees.

Seriously, my breasts are so big… They look smaller due to the sportswear correction, but they're still so big. I was just obsessed with otaku sentiments and thought they were just really big, but as I exercise and use my body more specifically, I realize how ridiculously big they are.

"This time, don't spread your legs, but use both hands to hold your knees together as much as possible so that they don't spread apart…"

"Excuse me, wait a minute."

"yes?"

"This… is too, peeling off…."

When I tried the pose, there was a really huge problem… It was a pose where my legs and upper body were closer together than any other pose, so my leggings were naturally pulled up, exposing almost half of my butt.

Seriously, my chest and hips… I was embarrassed to the point where I wondered what to do with them, so I stood up, then saw the training jacket that was left on the sit-up table, and a good idea came to me, so I immediately put it around my waist.

No… I tried to do it, but the trainer stopped me.

"Uh… I understand how you feel, but you shouldn't do that. I'll just stand in front and make sure you don't see."

"why?"

"If you step on my clothes while jumping, you might fall. It might seem like a trivial exercise, but if you do it wrong and twist your ankle or something, it could be a big deal... Don't worry, I won't let you see, so don't pay attention to me."

In the end, I had no choice but to trust the trainer and jump around like a rabbit.

As soon as I got into the pose, I felt my leggings halfway come off, exposing my butt, but I made sure that my trainer was standing right in front of me, so I figured he wouldn't be able to see, and did as he told me.

"If you do that, press down firmly so that both knees don't spread apart, and keep pressing down. Yes, while maintaining the rhythm, tighten your stomach so that you don't fall forward or backward when you run... Okay, I'll do this for one minute. Start."

"…Haat, ah, haa, ah… over there…."

"Hmm…."

Right away, I started jumping around, but this time I ran into trouble again. I ignored the bottom and went forward, and this time the top… My chest shook violently.

Compared to when I wear normal clothes, it's definitely less severe, but this is a bit much. It shakes so much that I wonder if it's holding it properly. It's shaking so much that it touches my chin.

I think it would be better not to do this exercise. It's too much of a total mess... As I was thinking that, the trainer suddenly grabbed my chest with both hands.

"Huh? Hey, wait a minute?!"

"Run."

"yes?!"

"Run, I'll hold your chest. If you shake it like this, it's not good for your chest. You don't want your chest to sag, do you?"

I don't want to be rude, but... still, this is... .

She wanders around, unable to find where to look, with her chest held in both hands. She's not kneading it, she's just holding it, her chest is lifted up as if it's caught in some kind of device that holds it in place, and she's frozen in place, as if her mind is in disarray and she's pressed the pause button.

"It's okay, just run."

…what the hell is this?

Even while thinking that way, for some reason I ended up running obediently. It wasn't because the trainer was grabbing my chest with some strange hand movement, but because he was really trying to keep me still, holding me just tight enough that it didn't hurt.

It's just exercise. Because it's exercise… .

As I kept my mouth shut and started jumping, I realized that it had definitely become much easier. My chest didn't shake much, and when my posture started to get a little off, the trainer grabbed my chest and lifted it up slightly to straighten my back.

But… it's too close.

As I was standing and slightly bending my legs to hold her chest, I felt the vibration of my body shaking while holding her chest in my hand, and I felt a hot heat between the new trainer's legs. It was so close to my face that when I tried to turn my head, he told me to look forward. Suddenly, I thought that if I looked down like this, my half-bare butt would be completely visible, but the heat right in front of my face and the trainer's hand holding my chest made me forget about that quickly.

What on earth is this? I thought to myself again, but my body moved to the trainer's chant. I jumped in place, counting one, two, one, two.

"Okay, one minute. Stop."

"Haa, haa, haa, haa."

The male scent slowly fades away, and I feel the weight of my chest that I had forgotten for a while. If it's an H-cup, it easily exceeds 1kg when combined... As that enormous weight returns, I wonder if my sense of reality is returning, or what on earth just happened.

What the hell did I just do… to my chest.

However, the trainer's calm attitude keeps trying to change my consciousness by saying that it was just exercise. The trainer looks at me with a calm face and then suddenly changes his face... Why is his face so red?

"Huh, huh-hem. Member Kim Hee-yeon... leggings."

"Huh? Oh, ah, uh."

While I was busy jumping around, I noticed that the leggings had fallen down considerably. The back part had slid down to where my legs and butt met, completely revealing my large butt, and the front part didn't even reach my pelvis and was so low that I was worried that my vagina would be visible if I lowered it a little more. If you look closely, you can see the pubic hair where the fine, fluffy hairs are growing. I was surprised to see that and pulled the leggings up.

"…I changed it for you because you were sweating a lot, but I think I'll have to change it again."

"Yes, yes…."

This time, it's so erect that it's really noticeable. Up until a moment ago, you could say it was reacting, but now it's so clearly erect that you can't help but say it's just erect.

The trainer's pants bulged strangely, and he slowly stood up as if something thick was pulsing loudly. The trainer seemed to notice this as he suddenly turned around and put both hands inside his pants.

"I'm sorry. There's nothing I can do about this."

As the trainer turned around after reloading, this time the waist of his pants was bulging out abnormally. It even seemed like he had pulled his pants up to his belly button… But did they reach there? That big?

It was so straight that I couldn't help but open my mouth because I could clearly see its size. My breasts are really big, but that's really stupid. Isn't that a bat? It makes me wonder if they put a karaoke microphone inside.

For some reason, my heart is pounding. The small room seems to be filled with a warm and fuzzy air, different from the heat from exercising.

If it's that big, is there any reason to wear clothes?

The trainer again suggested we take a short break, but this time I stood up instead of sitting down. I realized that the reason for this was because I was so horny that it would be even more noticeable if I sat down, so I stood with the trainer and took the break without saying anything.

But I couldn't help but be surprised by the words the trainer spoke as if trying to blow away the awkward atmosphere.

"Haha… but your skin is really smooth. You moved so roughly that it looks like you just dragged it down with your underwear… I'd think you were just wearing leggings."

"That, that can't be true."

"Right? If a beautiful woman like you were to receive something like this without even wearing panties… Wow, it's hard to even imagine."

I see the trembling of his pants in the corner of my eye, and my face gets so hot that I can't control my anger.

Of course, it's strange that you didn't notice when you were so naked. But I can't tell if the trainer really doesn't know or if he's just letting it slide. If you're not wearing anything, what on earth are you going to do? Are you pretending not to know or are you already aware and planning to do something about it now...?

I feel something tightening inside my stomach, as if something is pulling at me. A subtle tension, something different from the already faint sense of alertness that comes from being in contact with something that is considered exercise, fills me up, but the stupid thought that everything will be okay keeps lingering in my head and won't go away.

"Okay… Then, since it's not good to take too long of a break, let's try squats right away. First, let's see if you remember the posture correctly. Try doing it by yourself once."

"…yes."

Although he was a bit more nervous than before, he obediently spread his legs and took the pose.

If a stranger saw her, they might mistake her for wanting something, and she might have been caught not wearing panties, but instead of stopping, she obediently continued exercising.

Start with a Viking wide squat to the rhythm of the song. Swing your waist up and down, left and right, one two, one two.

Although the trainer couldn't see the condition of her lower body because of her large chest, when she raised her head, her gaze was definitely directed downwards.

Still, this is just exercise after all… .

"One, two, one, two."

"Hoo, hoo, haa, hoo."

I close my eyes, trying to ignore the gaze, and continue to sway my hips to the chant.
