“I don’t want to get in the same water that you bathed in.”
“Oh, so you’re okay with me getting in the same water that you bathed in?”
“Never mind. You first!” I quickly shouted.
I never really gave it too much thought when our parents were around, but now that I thought about it, I’d been sharing a bath with this guy every day.
Wait, doesn’t this mean... Isn’t it kinda like we— Okay, I need to calm down.
It was the perfect time to cool my head since Mizuto was in the bath right now. I needed to have a level head so I could launch my counterattack on him.
In order to get my thoughts together, I played the closed-room-murder game in my head—a game I had come up with where Mizuto was killed in a closed room, and I needed to think of all the possible tricks that could have been used to kill him.
But not even ten minutes passed before Mizuto came back, his hair still wet.
“I’m done,” he said.
“Uh...”
“What?”
Almost anyone who saw him with his hair wet—like it was right now—would no doubt think he was good-looking. In other words, that was a perfectly normal reaction. There wasn’t any meaning behind it. None at all.
“That was fast. Did you even wash yourself? You didn’t, did you?” I asked.
“At least wait for me to answer before deciding that I didn’t wash myself, because I did. Staying in the bath for too long just felt like a waste of time.”
I hated how he was always in a rush to move on to the next thing. He used to slow down for me when we first started dating, though...
But either way, I knew that the time had come to put my plan in motion. After mentally cleaning up Mizuto’s corpse in the imaginary closed room that I’d made, I stood up and said, “Okay, I’m going to take a bath now. I’ll kill you if you peep.”
“You wouldn’t even have to kill me. My eyes would rot and kill me first,” he retorted. Internally, I knew that this was his last chance to get smart with me.
Just in case, I kept glancing at the door of the bathroom while I got undressed. I never really gave it a second thought when our parents were around, but it dawned on me that I was getting naked in the same house that he was in. If that guy barged in on me taking a bath right now, no one would be around to help me.
But of course, that kind of aggression was beyond what that string bean was capable of. If he did barge in, I’d just bite off various parts of him.
After thoroughly cleaning and warming my body, I got out of the bath, wrapped my body in a dry towel, and dried my hair with a blow dryer.
And so it begins. I tightly gripped the towel tied around me with determination. There was no turning back now—I hadn’t brought a change of clothes to the bathroom with me. I had burned my figurative bridge of retreat all in order to back myself into a corner. I was definitely going to break his cool and calm demeanor.
I didn’t have a change of clothes, so there was only a single option—walk out like this in front of him!
As I looked at myself in the mirror, I could tell that my body had become more womanly since the two of us had dated, especially in my chest area. I had changed a lot in the past year—so much that even my mom and classmates were jealous.
Because I’d just gotten out of the bath, my exposed cleavage was slightly flushed, which was quite alluring, if I do say so myself.
A-And now I’m supposed to show all of this off to him?! I severely regretted not having at least brought a pair of underwear to change into, but I was sure that if I hadn’t gone this far, there was no way I would make that blockhead even flinch.
“All right,” I said, steeling my will. I left the bathroom and walked barefooted into the living room. “I-I’m done with my bath.”
“Fdsajfdsaj?!” Mizuto spewed out the tea he was drinking as soon as he saw me and began coughing. His reaction was even better than I had hoped!
I turned away so that he couldn’t see my relaxed expression.
“T-Towel? Why?!” he stammered.
“I live here, so what’s the problem?” I said, completely unfazed as I sat down diagonally from Mizuto on our L-shaped couch. Mizuto was looking off so far into the distance that he could probably see two days into the future. Even so, he was still stealing peeks at me.
“Yeah, but I’m here, you know?” he said. It was obvious that he had no idea how to react.
“So what? We’re siblings. Or maybe...” Taking this opportunity, I shot him a flirtatious glance as a smile crept across my face. “Or maybe you’re a bad boy who looks at their stepsibling with naughty eyes?”
“Geh.”
Aha ha ha! He’s getting so red! He’s blushing so hard! Serves you right!
Mizuto turned his back to me in order to escape my gaze, but he was still looking. I could feel his gaze on me. He couldn’t help but look at my cleavage or my thighs that were barely covered by my towel.
Heh heh, maybe this was too much stimulation for you? After all, you only knew me when I was still underdeveloped! Oh, you poor thing. You’ve only dated a girl who had the body of a child, and aren’t used to being around someone like me, someone who has the body of a woman. Wait, that girl was me. Maybe I should try crossing my legs again.
“Hnn!”
Oh, you saw that, didn’t you? You’re so obvious! You always try to play it cool, but look at you now. That facade is in pieces! Ha ha ha! This is so much fun!
I pretended to reach for the remote, using it as an excuse to put my cleavage on full display.
“Mngh!”
He’s looking. He’s looking so, so much. He’s smitten. He might be trying to keep a straight face, but it’s taking all that he has to do so. It felt as if I’d gotten my revenge on him, not just for today, but for that mess a year ago too. He’d never look at me at all back then, and now he couldn’t take his eyes off of me.
