Tsubomi and Mirei are top students at Knee-High Academy and are always together. When suspicions of lesbianism emerge, the evil hands of men creep up on them. The acts of rape escalate, with forced lesbian sex, toilet water torture blowjobs, bondage and toy torture rape, forced deep throat rape, and bukkake gangbang. They are scared and disgusted, but they can't help but feel pleasure. They are genuine, perverted, masochistic top students.
