Maika, a timid and introverted female student, has been targeted by a male teacher. He is a man with a terrible reputation as a sexual harasser who grins and touches students' bodies under the pretext of private lessons. The man handed Maika a smartphone, which contained secretly recorded videos of Maika changing in the locker room, Maika relieving herself in the toilet, and Maika's skirt peeking out while she was studying... "If this video gets spread... you'll be the one who'll be embarrassed, right? That would be a problem, wouldn't it?" the teacher said with a nasty smile. With no one to talk to, Maika had no choice but to take off her uniform on the spot... *This work is a sequel to ""I found a used sanitary napkin in the toilet two weeks ago, so today must be your ovulation day, right?"" A trash teacher who is a habitual voyeur and sexual harasser has his eye on her, and rapes her on her dangerous day. This is an excerpt from "Maika Nichizumi" (product number: dvaj00642).
