激務続きで疲労とストレス由来の不眠症に悩まされる友人のにとり。
誰かと夜を共に過ごし安心感が得られれば良く眠れるかもしれないということで添い寝をせがまれるも、そんな彼女に交換条件として見抜きをさせてもらうのだった。

My friend, Nitori, was having trouble sleeping due to fatigue and stress from constant overwork. She pestered me to sleep together, since she thought she might feel safe and sleep better if there's someone by her side. In exchange, I asked her to let me masturbate to her.
