The obsessive-compulsive, serious female teacher, Tsuji Miina, is forced to have sex with a garbage room uncle who is visiting her family, and is repeatedly brought to orgasm. (IPZZ-966)

Besides being earnest, Tsuji Miina has no other redeeming qualities. During a home visit to a student's house, she was shocked to find it a garbage dump reeking of nausea, a place she didn't want to set foot in. To calm herself, she drank the entire water bottle she carried, unaware that it had been laced with an aphrodisiac. By the time she realized it, her mind was already in chaos… her body and head were both limp, feeling incredibly good. "My pussy is bursting, hehe!" "The more serious a woman is, the greater the difference in the effects of the drug," "Come on, drink some more, make it even stronger." Give me more… I want to feel even better… The earnest teacher, drowning in the aphrodisiac, is trapped in an inescapable spiral of ecstasy.
