SONE-719 Seduction of a serious student by a sailor with raw breasts. The homeroom teacher can't keep up with the devilish charm of a young man who approaches her without a bra every day. Immoral sex in school. Ruka Itoi.

This is a record of my confession. I put my hands on my student. I gave in to desire. I succumbed to the temptation of my student, Ruka, who was wearing no bra. It's not that Ruka is bad. she is still a child. All faults are mine. No matter how much love is shown to you, no matter how many women use their weapons to invite you, you must refuse.
