“It’s all right, Onii-san~. Just stay put.”

“E-Even if you say so… hiii~!”

　I was currently being washed by my little sister’s friend and also, my girlfriend, Shiori-chan.

　She wiped every inch of my body with a towel that had plenty of body soap lathered on it.

　It wasn’t a direct touch, and it was the same towel I usually use, but my sense of touch was becoming more sensitive, and it was difficult to keep my composure.

“You’re so cute, Onii-san, I can’t stand it when you look at me like that~. How about you, Onii-san? Aren’t you getting horny~?”

“No, I’m not.”

　The question that chilled my heart made my heart jump.

　I reflexively shook my head and denied it.

　Then, Shiori-chan turned her gaze away as if she was unhappy, and sobbed.

“You’re right. My breasts don’t excite Onii-san… do they?”

“Whoa, I’m really horny, aren’t I?”

“Really!? I’m so happy!”

“I-I don’t think you should be happy about that…”

　Isn’t this girl really that indecent…?　

　I think her aggressiveness is too much.

“Well then, if you’ll excuse me~.”

“…Huh, wh-what do you think you’re doing!?”

“Hmm~? I can’t wash the bottom half of Onii-san with a bathing suit on.”

“You don’t have to wash it! I’ll do it myself!”

“Don’t worry, Onii-san, I’ll take care of everything~.”

“That’s really not a good idea…”

　When I’m in the bathroom with a middle school girl, it’s like I already have two strikes, but when the bottom half of my body shows up, it’s gonna be a third strike.

　I’m going to have to defend this line at all costs…!

“You want me to take off first, right? I understand.”

“That’s just an exaggeration!”

“Do you want me to take it off, Onii-san? Or do you prefer to watch me take it off~?”

“I’m telling you, that’s not it!!”

　At this rate, without joking, it would be like practicing health and physical education.

　If Shiori-chan was joking, fine, but right now she was serious in her eyes.

　I turned the shower on full blast, rinsed myself off, and sat up quickly.

“I-I’m leaving already.”

“Oh, what are you trying to do? It’s my turn after Onii-san.”

“Oh, is that so? All the more reason for me to leave already.”

“No, Onii-san, you have to wash my body.”

　She squeezes my right hand and stops me in my tracks, looking up at me pleadingly.

　My cheeks were tainted with vermilion color, and I shook my head like a barking dog trying to catch water.

“J-Just do it yourself!”

“It’s a win-win situation, Onii-san~, we’re living together, and we should support each other.”

“Where are you going with this?”

“Where do you want to start? My hair? Or my body?”

　Shiori-chan tilted her head as she placed her hands on her chest and asked me these questions.

　I blushed even more and left the bathroom to escape.

“I-I’ve already told you, I’m not going to wash you! Even if the position of the man and woman are reversed and that woman is still underage, it’s a real police matter!”

“Mou~…Onii-san, are you composed of only reasoning…?”

　Shiori-chan puffed out her cheeks and stared at me in frustration.

　I slipped out of the bathroom and quickly wiped my body and left the place.

　Good grief… It’s hard for me because I’m not a person who’s only made up of reasoning…

　I did my best to lower my elevated body temperature with something other than hot water.

　★

“Hmm? What’s wrong, Onii-chan? You called me out of the blue at this hour.”

　I went back to my room and called my little sister, Yuzu.

　After a few calls, Yuzu picked up the phone and let out an absent-minded voice.

　I couldn’t see her expression through the phone, but I started to question her, changing my expression.

“Can you please send Shiori-chan home as soon as possible?”

“Eh? Why? Did you two get into a fight?”

“There was no fight. It’s just that my virtue is in danger.”

“Ha?”

“Anyway, I’m in danger, you know. It’s not good for me and Shiori-chan to be alone in this house. That’s for sure. That’s why I’m trying to get Shiori-chan home as soon as possible.”

“I don’t know about you, but I’m on Shiori-chan’s side. I don’t care what happens to Onii-chan.”

“You’re acting as if you’re not my little sister at all!”

　She took the side of her friend rather than her own brother.

　While I was raging through my phone, Yuzu continued.

“That reminds me, I know already. I heard that Onii-chan started dating Shiori-chan. Is it a trial? That’s what it seems like.”

“You heard that?”

“Well, yeah. It’s okay then. It’s perfect for Onii-chan who’s shy and lacking in energy. If you get married, then Shiori-chan will become my sister. Everyone will be happy.”

“Marriage is a bit of a leap, don’t you think…? Besides, we haven’t even officially started dating yet.”

“Then why don’t you go out with her? Wouldn’t that solve everything? It’s not like you’re doing anything half-hearted.”

“That’s what I’m saying…”

　It’s hard to look at a person who you’ve only seen as your little sister’s friend as the opposite sex so easily.

　I cleared my throat and cut off the flow of the conversation, and then carefully began to speak again.

“Anyway, is there any way we can get Shiori-chan to go home? I have a feeling that living with her like this is going to be a serious problem, and you never know what she might do to me.”

“Hmm. I don’t want to say anything unnecessary to Onii-chan, as I’m in the camp of getting to the finish line as soon as possible… Well, it can’t be helped, I’ll teach Onii-chan how to stop Shiori-chan’s rampage.”

“Yes, please do by all means.”

“Well, listen carefully─”

　Yuzu’s voice, which can be heard through the phone, becomes slightly quieter.

　In a whispered tone of voice, Yuzu taught me how to counter Shiori-chan.

“No, but that’s─”

“Well, do it or don’t do it, that’s for Onii-chan to decide. I have an early day tomorrow, so I’m going to go now. Good night, Onii-chan.”

“Eh, oi, wait.”

　The call went out.

　I put my phone down on the table and dove into bed.

　Five more days until Yuzu comes back… It’s a long time…

　I let out a small sigh as I gazed at the white ceiling.
