Devote

Devote is a Japanese erotic visual novel which takes place in a school. The player takes on the role of a male student who is summoned by four girls — Yuri Kimura, Kaori Hanaoka, Mio Shimada, and Shiho Uchida — to an empty classroom after school hours. To the protagonist's bewilderment, they tell him that they want him to make love to them, and who is he to refuse? The ending of the game varies depending on which girl the player chooses to give the most attention to.
