My Cool and Straightforward Girlfriend Won't Let Me Sleep Today Either - Chapter 20

Chapter 20: My 4th-Year Girlfriend in Her Adventurous Phase

Today is sauna date day.

We arrived at a private sauna facility, which is currently popular.

The price is reasonable considering it’s a date, although it’s not exactly cheap.

After completing the procedures at the counter by stating that we had a reservation, the staff began their explanation.

“We would like to explain the usage and precautions of our sauna facility to first-time users. This explanation will take about 5 minutes, but this time is not included in the rental time, so please rest assured.”

So, we listened for about 5 minutes.

To summarize roughly:

– Wear swimwear inside the sauna.
– Prohibited from severely dirtying the room.
– Bringing drinks into the sauna is prohibited; if you want to drink, do it outside.
– Adjusting the sauna temperature must be requested to the staff; adjusting it yourself is not allowed.
– Use of aroma oils is prohibited.
– If you feel unwell, stop using the sauna immediately.

The staff seemed to be stating only the obvious things.

But well… I guess they must be dealing with an increase in unruly customers due to the sauna boom.

Yeah, I’ll make sure not to be a nuisance customer…

“Explanation complete. Please enjoy your time.”

“Shall we go?”

I was led by Natsuki to the sauna and various other amenities in the private room.

The room consists of a sauna room, a cold water bath, reclining chairs, a shower room, and a changing room, all compactly arranged.

Indeed, with these facilities, the price for a 90-minute rental doesn’t seem unreasonable.

“This is a nice room.”

“…I’ll go change first.”

Natsuki said so and headed to the changing room set up in the private room.

In just a few minutes, Natsuki finished changing and—

Natsuki appeared in front of me in a sexy black bikini with frills at the neckline.

Although we discussed renting swimwear, she said, “I don’t want to wear swimwear that someone else has worn,” so she brought her own.

“That swimsuit looks really cute.”

As an introverted person, I’ve been scolded by Natsuki many times. “Just praise her, at least praise her,” my inner voice urged. Before I knew it, I was praising Natsuki’s swimsuit as cute.

“Yeah, yeah.”

“Now, I’ll go change.”

I entered the changing room to quickly change.

For a guy, it’s just taking off and putting on. I was supposed to change into the swimwear I brought from home, but—

“Natsuki-san?”

I peeked out of the changing room and looked at Natsuki. Because, because…

The swimsuit in my bag had been swapped with a different one.

Yes, instead of knee-length surf shorts, it was knee-length half-spats swimwear.

“That’s because your swimsuit looked tattered, so I bought recommended ones.”

Natsuki said it so coolly.

It’s true that my swimsuit was getting tattered.

However, the “tattered” part was more of an excuse than the real reason.

By the fourth year of dating, you could somehow understand Natsuki’s true intentions.

“If you want to go swimming in the training pool together, you should just say it instead of switching my surf shorts for new swimwear, right?”

Yes, Natsuki surely wants to go to the pool with me.

Not to have fun, but to train.

“That’s not true.”

“No… it’s just that surf shorts float in the training pool, so you went out of your way to buy me a new competitive swimsuit, right?”

“…Why don’t you change your clothes quickly?”

She is so blunt and tries to hide her shyness as she rushes me.

Anyway, that’s it. It’s really easy to understand.

I wore a swimsuit with half spats, perfect for swimming in the training pool.

So, when I come out of the changing room, Natsuki stares at me intently.

“W-What is it?”

“No, rather than those loose surf shorts, these ones have a solid silhouette and look cooler…”

“Yeah, you’re right. In the past, these kinds of things used to be made fun of, but recently, swimsuits specialized for swimming like these seem to be quite popular, huh?”

“But still…”

Suddenly, Natsuki approached and slipped her hand into my swimsuit, fondling my crotch.

“H-Hey, this isn’t the place for that kind of behavior…”

“Sigh… just stay still for a moment.”

With a bewildered expression, Natsuki groped my crotch.

But soon, Natsuki’s hand stopped.

“W-What was that for?”
“Your ‘position’ down there seemed a bit off, so I just adjusted it.”

I glanced at my lower abdomen.

It feels like everything is arranged better than before, and somehow it looks cleaner.

As I was admiring this, Natsuki lightly pinched my side.

“Come on, let’s go already?”

“No, we should shower first.”

As etiquette, we should clean ourselves before entering the sauna.

So, Natsuki and I washed ourselves off in the shower room provided in the facility.

Finally, we dared to challenge the sauna.

“Shall we go in?”

Natsuki took my hand, and I entered the sauna filled with heat.

I immediately exclaimed.

“…Hot!”

“It’s normal, isn’t it?”

Natsuki, who is a bit assertive, says so, a bench in the sauna room? She laid out a towel and sat down.

I mimicked her and sat beside Natsuki.

Since it was mentioned in an online article that enjoying the sauna quietly is also an option, for the time being, we silently surrendered ourselves to the heat.

Not even a minute had passed since entering the sauna when sweat began to pour out from all over our bodies.

Natsuki and I both became drenched in sweat, enduring the heat.

And after 5 to 6 minutes had passed.

We hurriedly left the sauna, seemingly fleeing from the heat.

Then, we lightly poured cold water over ourselves and entered the cold water bath.

“…Cold. N-Natsuki are you okay?”

“I-I-I’m gonna be fine with this much.”

“I think we’re supposed to stay in the cold bath for 1 to 2 minutes…”

Natsuki and I, not accustomed to the cold water bath, shivered uncontrollably.

Nevertheless, since we came to the sauna, we wanted to fully enjoy it.

Suppressing the desire to immediately leave the cold water bath, we endured for the suggested 1 to 2 minutes.

“Alright, that’s enough, right?”

“…Lend me your hand.”

“Are you okay?”

I took Natsumi’s hand, which was trembling like a fawn.

“I-I’m fine…”

With weak steps, Natsuki made her way to the reclining chair provided for outdoor relaxation and lay down.

I also lay down on a similar reclining chair and began to space out.

After resting on the reclining chair for about 3 minutes, I asked Natsuki.

“Do you understand the benefits of the sauna?”

“…Mm, it’s alright. How about you?”

“I still don’t really get it.”

“For now, let’s go to the second set…”

“We came to the sauna, after all. Let’s thoroughly enjoy it today…”

We’re spending quite a bit of money.
We don’t want it to end without feeling its benefits.

Natsuki and I repeated the process of sauna, cold water bath, and outdoor relaxation.

And then, the moment arrived.

It was during the third set, while resting on the reclining chair.

“It’s true that ‘sauna therapy’ really exists.”

I was feeling an indescribable sense of comfort.

My mind, which was vacant just a moment ago, now feels strangely clear.

It seems like Natsuki is also experiencing the same sense of comfort…

“This might be good…”

It seems like she’s genuinely feeling the comfort.

Facing her, I smiled.

“Saunas aren’t so bad.”

“I used to think saunas were just… but trying new things is really important…”

“Yeah, you never know until you try…”

Both of us experienced an unknown pleasure.

There are still many enjoyable things in this world.

You can only obtain something by trying.

At that moment, Natsuki, with her mind cleared by the sauna experience, mentioned something she wanted to try.

“…Next time we do it, can I try tying Minato’s hands and feet?”

While lying on the reclining chair, Natsuki stared at me with a serious expression.

It seems that bringing Natsuki to the sauna was a mistake.

After experiencing new sensations, Natsuki transformed into an explorer seeking further unknown experiences, and all I could do was smile wryly.
