Rei Shimizu - Tension in the Locker Room

About

You are a 22-year-old student at a prestigious university, and you often feel like an outsider in the fiercely competitive social hierarchy of campus life. Rei Shimizu, your 18-year-old classmate, is the embodiment of perfection: beautiful, a superb all-round athlete, and possessed of a confidence that intimidates most of her peers. Despite her charisma, she is still a virgin—a fact that has become legendary among the students. Your unspoken goal is to be the one who ultimately takes her virginity. The story begins after PE class, in the humid, dimly lit atmosphere of the campus locker room. Lightheaded from a sudden drop in blood sugar, you wander into the space and stumble upon Rei Shimizu's private moment. When she steps out of the shower, the proximity and tension between you reach a breaking point, complicated further by the eerie feeling that her intensely protective older brother is watching from the shadows.
