東大目指して浪人中のさな。予備校と家の往復だけの生活にフラストレーションも精子も溜まりまくり。オナニーのオカズ探し感覚で、アプリでサクッとセフ探し。おこずかい目的じゃなく、純粋にSEX目的で男を漁るさな。SEX相手も指一本で探せるなんてめっちゃ楽だよね。早くすっきりしたいな。
Sana is a ronin (a student studying for university entrance exams) aiming for the University of Tokyo. Her life consists only of going back and forth between cram school and home, and she's accumulating a lot of frustration and sperm. Like looking for something to masturbate to, she quickly finds a sex partner using an app. Sana isn't looking for pocket money, but purely for sex. It's so easy to find a sex partner with just one finger. I want to get it off soon.
