A seemingly innocent, short-haired girl who is passionate about volunteering, but harbors a masochistic desire to have her mind and vagina manipulated. Shizuoka University, Faculty of Environmental Studies, Sera Tsubaki, AV debut CAWB-023

Sera Shizuku, a student in the Department of Environmental Science at a university in Shizuoka Prefecture. War, political corruption, the desire for validation on social media… In order to purify the murky society, humanity, and the bleak world a little, she is a simple female college student who volunteers by picking up trash on the streets every day. To make the world purer… Behind her upright heart lies a secret she can't tell anyone. "Actually, I'm a real masochist." Choking, spanking, deep throating, nipple playing—she has a desire to be treated roughly. Whenever she's insulted, her vagina becomes incredibly wet. With the spirit she cultivated while volunteering, can she clean the penises of older men? Just like her previous service to society, can she serve this enormous phallus? This is a one-of-a-kind… shocking debut work of internal ejaculation. As Sera-san wished, we plunged her into a chaotic mix of life and death and bodily fluids, completely ruining her.
