"Teacher, aren't you embarrassed to gulp down pee in a place like this?" Hinako, a student who has a crush on me, finds me cheating on her with another teacher, and in exchange for keeping it a secret, she invites me out on an after-school date. Wanting to make me hers, she overwrites my sexual preferences by peeing on me one after another at family restaurants, in parking lots, in toilets, outside... I'm showered with and forced to drink the forbidden, 100% pure, pure, high school girl holy water until I'm drowning, and before I know it, I'm begging for pee myself...
