[Chinese]SONE-940 Every day for seven days, I've been slipping aphrodisiacs into my young female homeroom teacher. By the seventh day, she had transformed into a horny bitch, constantly begging for her student's dick. Riri Nanamori

A beautiful and famous female teacher is popular among students, a total babe magnet. In her class, there were two male students who excelled in chemistry. The aphrodisiac they created in the classroom was incredibly potent, filling one's mind with lust and making their crotch hot and throbbing. They haven't noticed yet, but it was quite a revolutionary drug as an energy booster. After making her drink the stuff for fun over several days, she suddenly collapses in class. We rush her to the nurse's office, and even though she's out of it, her body is hot and her crotch is wet. The students, excited by such a sight, release their youthful desires through sex with Riri and Riri. After making it a habit to drug the teacher with aphrodisiacs and have sex, Riri with hazy memories visits the science club room, sees the method of concocting aphrodisiacs, and summons the students to the classroom… The mistakes made by chemists who would later become famous during their student days were an emotional and erotic youth.
