After 7 Days Of Daily Dosing Of An Aphrodisiac To A Homeroom Teacher Close To Her Age, She Turned Into A Horny Female Who Repeatedly Craves Her Student's Dick. Riri Nanatsumori

Riri, a beautiful and famous teacher, is popular among her students. In her class, there are two male students who excel in chemistry. The aphrodisiac they create in the classroom is quite potent, filling their minds with lust and making their crotches throb with heat. They don't realize it yet, but it's a groundbreaking stamina-enhancing drug. They give Riri the drug as a joke, and a few days later, she collapses in the classroom. Rushed to the infirmary, she's dazed but her body is hot and her crotch is wet. Excited by the sight, the students release their youthful lust through sex with Riri. As drugging the teacher and having sex becomes routine, Riri, with hazy memories, visits the science club room, sees the recipe for the aphrodisiac, and calls the students to the classroom... The mistakes made by the future famous chemists in their student days were an emotional and erotic youth.
