Nei-san was silent the whole time she was driving the car to the meet up point.
Looking at the night town through the window...It's already 11:00
The sky looks dim...It might be rainy tomorrow.
I can hear the voice of the navigation system of the car from time to time...「...Yo-chan, sorry」
Nei-san suddenly muttered.
「I...become strange when I see fire from time to time. I usually endure it until I can come back to my room. I was alone with Yo-chan so my heart seems to have burst out...」
Nei-san's face looks lonely.
「...I was gross, wasn't I?」
I
「Please don't be ridiculous! Nei-san is always beautiful!」
...I threw out my emotions.
「Nei-san is the most beautiful girl in the world! Beautiful and gentle, you're my Onee-chan!」
「...Yo-chan」
「I can't be a substitute to your late brother but, I'll do anything I can!」Nei-san shook her head.
「...I'm an insane woman. Getting aroused, I masturbate in my bed everyday! I'm such a disgusting woman!」
Nei-san spoke while storing tears in her eyes.
「Even I masturbate! I can do it five time in one night at best!」
I...confessed everything.
「I have always been alone when I entered high school. It's lonely, scary...I masturbated everyday. I even did it seven times on Sunday...!」
「...Yo-chan?」
「My head was full of delusions...I always thought about raping Yukino. I've never thought about having happy sex with Yukino...I just always think about raping Yukino in various places...I always masturbate that way! I'm the disgusting one here!」That's my life since the entrance ceremony.
I always thought of Yukino as a sexual target.
I'm that kind of disgusting human.「...I'm a woman who's having delusions of having sex with her dead brother! Isn't that disgusting?!」
「No, I'm three times more disgusting!」
「I'm completely disgusting...!」
「I'm worse! I'm ten times worse than Nei-san!」
「Then, I'm a woman that's 100 times worse than Yo-chan!」
「Then, I'm 10,000 times worse! I'm already a disgusting man!」...Nei-san laughed out.
「...Nei-san?」
She's looking straight up front while holding the steering wheel...
「...We're like idiots. That's so funny」
「...Right. That's funny」Nei-san smiled.
「It can't be helped...We're siblings after all!」
「...Eh?」
「Aren't we masturbation loving siblings?」
「...Ah, Yes」
「...You see」Nei-san spoke to me while driving.
The seat belt who looks like a tuck on a Yukata strongly penetrates between Nei-san's breasts...「...Yo-chan」
Nei-san spoke to me in a dry voice.
「What?」
The car stops at a red light...
Nei-san looked at me.「...You're really going to become by brother?」
The answer's already obvious.
「...What should I do?」
Nei-san thought for a moment, then answered.
「Should we get it in form?」
「...Form?」
「Didn't I tell you that Yuzuki adopted Maru-chan?」
「...Yes」
「You see...I was told that I can't be adopted.」
「...Nei-san?」
「My parents and brother were killed...I don't even know who my other relatives are. Sensei just put in 『Kuromori』as my family in the registry」
