I Accidentally Said “I Want a S○x Partner” in the Class Group on LINE, and the School Idol Responded - Chapter 6

[―Good evening, Hashiguchi-kun. It’s me. Can you unlock the door for me?]

A little after 9 PM.

I was finishing my first solo instant noodles while working on my homework when the intercom rang. Checking the monitor, I saw the visitor standing at the entrance. As expected, it was my classmate, the black-haired beauty.

“Ah, I’ll open it now.”

“Thank you.”

I unlocked the door and let Shinozaki in. The nervous excitement I’d felt earlier came back.

What would happen now that she was inside? Would we finally do what we couldn’t do last time, the first time?

Before I could think too much, she was at the door.

“Good evening. I’m sorry for coming so late.”

“It’s fine. Come in.”

I tried to stay calm.

Shinozaki was still in her school summer uniform, which meant she hadn’t gone home at all after school. There were a lot of things about her that made me worried. Was it really okay for her to be out this late?

But I figured some things weren’t worth digging into. We hadn’t done anything yet, but we had a s○x partner arrangement. That meant this was a practical, straightforward relationship, and it would be pointless to overthink things.

“This is a nice room. Are you going to live here from now on?”

“No, just until I finish high school. This is only for practice.”

“Come to think of it, that’s what we were talking about… Can I sit?”

“Ah, of course.”

I let her sit at the table, poured some barley tea, and handed it to her. She said thanks, and I took the seat across from her.

“…So, can I ask why you came over tonight all of a sudden?”

I already had a pretty good idea what the answer would be.

But I asked anyway,

“Isn’t it obvious?”

She takes a sip of tea while her expression is glossy in some way.

“The first time for our s○x partner arrangement.”

“!”

“Do you think there’s any other reason?”

“…Yeah.”

It was a silly question.

“Ever since the first time it got postponed, I’ve been really looking forward to this. I’m like a puppy that’s been teased and kept waiting… Of course, I’m nervous, but I can’t wait to feel this unknown pleasure that might make me forget all my daily frustrations.”

Maybe Shinozaki… is surprisingly curious about s○x. At school, she’s seen as untouchable, a top student just below me in grades, but that’s only one side of her. The public face of Shinozaki Mikage.

“Weren’t you looking forward to it too, Hashiguchi-kun?”

“Yeah, of course… I’ve been thinking about it a lot, over and over…”

“Hehe, I see. Then, can I stay over tonight?”

“…Stay over?”

“Is that a no?”

“No, I don’t mind… but is it really okay? You know… with your parents and stuff?”

“It’s fine… my parents aren’t the type to worry about me.”

Shinozaki’s expression was slightly serious.

But then she quickly brightened and said,

“Hey… shall we take a bath together first?”

She said that.

I widened my eyes.

“Ta-take a bath together…?”

“Let’s just think of it as practice. I won’t force you if you don’t want to.”

Shinozaki was making an outrageous proposal…

She might actually be pretty s○xual.

But I didn’t mind at all.

In fact, I wanted it.

“…I don’t mind, so if you really want to, let’s do it.”

We were about to take the next step, so there was no way a shared bath would faze us.

“Then, let’s go right away.”

She stood up calmly.

I had no objections.

I had already prepared the bath, expecting this.

Nothing was in the way.

※

In the brand-new changing room of my first apartment, there were two shadows.

It’s mine and Shinozaki’s.

We stood facing each other by the sink, frozen in place, fully dressed and unsure of who should undress first.

“…Hashiguchi-kun, aren’t you going to take your clothes off?”

“…Shinozaki, aren’t you?”

We were hesitating as each of us was embarrassed to go first.

Would we even be able to go through with this at this pace?

I was starting to worry about how slow we were.

“Hmm… I guess I should go first.”

Shinozaki gripped the buttons of her summer blouse.

“I invited you to bathe together, and I proposed our arrangement. Plus, they say courage is a woman’s trait.”

“W-wait, wait. If that’s the case, I should go first as the guy.”

Seeing her start to undress, I quickly grabbed my own shirt. There was no way I could just stand there and watch her undress.

So, in the end, we started undressing at the same time.

Shinozaki had already undone all her blouse buttons. Underneath, she was wearing a white undershirt, so her bra wasn’t immediately visible.

I, on the other hand, was bare-chested under my shirt.

“Oh… you have a surprisingly nice body.”

Shinozaki was staring at my upper body as I set my shirt aside.

“Do you work out?”

“Yeah… My dad didn’t only expect good grades and behavior. He said I should look presentable at all times, so I was forced to use a fitness bike and do weight training every day.”

I didn’t have six-pack abs, but I was in decent shape. Honestly, being forced to do it probably wasn’t so bad.

“Somehow… I’m suddenly embarrassed to undress.”

“…Why?”

“I’m a bit chubby compared to you…”

“No. If you called yourself chubby, half the women in the world would get mad.”

Shinozaki wasn’t chubby at all. She was slim, with a body that many girls envied, yet still had an attractive and curvy figure.

“That’s because you’ve never seen me naked… I just look slim in clothes. I’m a mess underneath.”

“I’ve never seen you, but I can tell you’re just underestimating yourself.”

Shinozaki seemed to accept it and said, “…Alright then, I’ll undress, but don’t be disappointed, alright?” She started lowering the zipper of her skirt.

My heart jumped as she slid the skirt down her hips.

Beneath, her long legs were covered in black tights. Under that were white panties.

I swallowed hard, and Shinozaki said,

“…These aren’t special or anything, so don’t stare too much.”

But, for a high school boy, my self-control is hard.

Shinozaki’s panties weren’t fancy or anything. Like she said, they looked cheap. It’s probably something sold in bulk at a discount store.

That was fine, but I was a bit surprised that Shinozaki wore such simple underwear. I had thought she paid attention even to things no one could see, but apparently not.

Still… maybe it says something about her home life. I don’t really know for sure, though.

While thinking that, I made sure to take off my own clothes and ended up in just my boxer shorts.

Shinozaki took off her tights and undershirt, and her bra was finally visible. It didn’t match her panties, but it was the same plain white color and looked cheap, too. It covered her full chest tightly, and maybe it wasn’t even the right size.

“You really aren’t chubby at all.”

I ignored the underwear for now and tried to focus elsewhere.

Shinozaki was half-naked as she looked slim and graceful, and even the cheap underwear couldn’t hide her curves.

She crossed her arms shyly and looked away.

“You can pinch my stomach.”

“It’s normal for women to have some fat under the skin. Yours is totally fine. Honestly, I like your body more than a model’s.”

“T-thank you…”

Shinozaki’s face was bright red, and it looked fresh and cute.

“Anyway… since we’re doing this as s○x partner, we can’t just take our time now… I need to take off my underwear too…”

“Then… I’ll go ahead and take mine off first.”

I felt embarrassed, but at the same time, there was a part of me that wanted to show myself to Shinozaki and see her.

So I didn’t think too much and pulled down my boxers.

The look on Shinozaki’s face at that moment, I might never forget it.

“…O-okay, then I’ll take mine off too.”

Inspired by me, Shinozaki gathered her courage and revealed herself completely. She was so tempting that I couldn’t look away.

Once we had shown each other, the awkwardness started to fade. As we took a bath together, the embarrassment lessened, and all we noticed was each other’s bodies. We touched each other freely, and it felt mutual.

After the bath, things went smoothly. We opened the box we had prepared earlier and got ready on the bed.

“I just want to check one last time… are you sure it’s fine if it’s me?”

“Yes… so you don’t hold back.”

After hearing that, there was no need for more words.

And so, we spent the first night of our agreement together. In that sweet moment, all extra thoughts and discomfort disappeared completely.
