No matter how many times I tell him, the volleyball team captain who never wears a bra to school is Minato Namikaze (DRPT-117).

This is a summer-long battle (a nipple fight) between a volleyball team captain who refuses to wear a bra and a teacher who wants her to. The volleyball team captain, completely inexperienced in sex, seems to have a strong aversion to wearing a bra, going to school without one every day! Her homeroom teacher, unable to bear seeing her nipples peeking out from under her shirt, tries to remind her, but the captain completely ignores her! She even provokes the teacher: "Why do you want to see my nipples?" "Does that arouse you?"! When the teacher touches her nipples, the captain trembles with pleasure! Having discovered the pleasure of nipples, the girl's desires become uncontrollable, greedily pursuing every form of pleasure in the classroom, the clubroom, and the teacher's home!
