I Got Cheated On, so I Thought I’d Cheat Back and Went to a Group Date, I Ran Into a Classmate Who Used to Boss Me Around and Now We’re Living Together - Chapter 26
“Then, I’ll start washing your back, okay?”
“Ah, yeah… please.”
The moment I replied, a soapy towel touched my back.
So began the back-washing session by Nene-san.
“Does it hurt?”
“I-it’s fine…”
As I answered her gentle question, I found myself thinking. When was the last time I felt someone behind me in the bath like this? Probably not since I was a kid, when my parents used to wash me.
Rinne never played around with me like this. For someone with such loose views on chastity, she strangely kept her personal space rigid. Shared baths were a complete no-go for her.
And yet here was Nene-san, someone who is not even my girlfriend, putting herself in this situation.
And as I could see in the mirror in front of me, the Nene-san behind me was… in a swimsuit.
“…Why… a swimsuit?”
I had to ask. It was the last thing I expected. If all she wanted was to wash my back, her usual clothes would’ve been enough.
“Well… think of it as a service. Yeah, service.”
“…Service?”
“I mean, if I just came in wearing normal clothes… it wouldn’t be very fun, right?”
“Does washing my back need to be fun…?”
“…But this outfit isn’t a bad thing for Sousuke, right?”
“Well… it’s not…”
Just getting my back washed was already a luxury. Add her in a swimsuit on top of that? No guy would complain.
“You know, Sousuke’s actually got a pretty nice body…”
She suddenly said that, stopping the towel and running her hands over my shoulders and abs… There’s no hesitation at all. Not that I minded.
“…Is this thanks to that nightly bodyweight training you always do?”
“I think so… it’s the result of small efforts adding up. I’ve been at it since my high school debut, so it’s been about four years now.”
“Whoa… Meanwhile, I’m all soft and squishy. Compared to you, I’m starting to feel embarrassed…”
She went back to scrubbing as she mumbled that.
…Nene-san is squishy?
Back in the fitting room the other day, she definitely didn’t seem that way…
I started to turn around, wanting to check her stomach again,
“―D-Don’t look…”
She pressed her hand against my cheek and firmly pushed my face back to the front.
A natural move for a girl, but it felt unfair to me.
The more something’s hidden, the more I want to see it.
That kind of human weakness welled up in me.
And besides… I kind of wanted to mess with Nene-san. Not out of revenge for middle school, but because flipping our old relationship upside down had its own kind of charm. To think that the Nene-san could be at my mercy… There was a strange dreamlike appeal to that.
“Don’t you think it’s unfair that only you get to touch me?”
So I said to Nene-san.
“Eh?”
“You touched my body, right? Then I want to touch your soft and squishy stomach too.”
It sounded pretty perverted, but I said it anyway.
I had no intention of backing down.
And then Nene-san,
“…Y-You really want to touch it?”
Her embarrassed voice carried a kind of hesitation, but at the same time, I could feel it—if I pushed a little, she might actually give in. And I had no reason not to.
“Yeah. Of course I want to.”
“Y-you want to.”
“I’m curious about Nene-san’s soft belly.”
“B-But it’s embarrassing…”
“You showed up dressed like that, and now you say that?”
“T-that’s true, but still…”
“Right? And it’s not like it costs you anything. Please, just let me.”
I didn’t even consider the risk of being rejected or her hating me for pushing too far. Maybe it was arrogance, but I was convinced she’d let me. There’s no proof and just a gut feeling. Nene-san would forgive me. She’d allow it.
“T-then… just once, okay?”
—There it was.
My faith pays off.
I’d won the gamble.
Or maybe Nene-san was just too easy, but either way, I got my way…
“…S-should I move in front of you?”
“Ah, yeah, if you don’t mind.”
“Alright…”
Nene-san was blushing as he shuffled around until she stood in front of me.
Once again, my eyes were drawn to the black frilled swimsuit. It wasn’t cut to show cleavage, but maybe because of that, the bare stomach it revealed stood out even more.
Nene-san had called it soft, but it wasn’t honestly that at all. Just like when I’d seen her before, her waist was slim and well-shaped. If this counted as soft, then every girl in the world would qualify.
“D-Don’t stare so much…”
Now that she was right in front of me, her embarrassment overflowed, and just like during the fitting room incident, she tried to cover her stomach with her hands.
But I didn’t let her. I caught her wrists and gently pulled her hands away.
“You can’t hide it.”
“Ah…”
“You promised I could touch you, so don’t cover it up.”
Her pale belly button was exposed, and I couldn’t take my eyes off it. It was small and cute and was perfectly shaped. I was probably the first guy to ever stare at it this closely.
“I’m gonna touch, okay?”
“Y-Yeah…”
I wasn’t here just to look, so I got to it right away. After getting her permission once more, I traced my fingers over her fair skin. Smooth… so this was what Nene-san felt like. A strange sort of awe filled me as I gently pressed and kneaded her stomach.
“Ahh… N-no… d-don’t…”
Her voice trembled as if to resist, but she didn’t push me away. She let me keep going while quietly accepting it. Amazing. If I went back and told my middle school self, “You’ll get to rub Nene-san’s stomach one day,” he’d probably think I was high on something.
That’s how unthinkable this was, given what our relationship used to be. I lost myself in the sensation and was unable to figure out when to stop. It just felt too good.
“…Y-you’ve really got something going on down there…”
Her face was flushed bright red as she said that, with her eyes flicking down. What she saw was the bulge under my towel.
“So… this happened because of me?”
“Yeah…”
“I see… Then maybe I should take responsibility…? Let me take it…”
“R-Responsibility…?”
“…You know exactly what I mean.”
As she spoke, Nene-san’s hand moved. She slipped toward the towel at my waist.
“…You’ve been playing with my stomach all this time…. so there’s no backing out now, got it…?”
…This whole touching thing started as payback for her touching me first, but I wasn’t about to argue. I didn’t refuse.
In the end, Nene-san’s swimsuit ended up stained white. But that’s something only the two of us will ever know.
