Only good-looking guys can hook up with pretty girls. It's sad, but this is the harsh reality of the modern world. However, in a school in another world line, anyone can have sex with whomever they want, whenever they want! Female teachers, health teachers, female classmates they're interested in...no one will refuse sex! That's right, in this world line, sex is just a casual act, like a greeting. It's totally OK even if you're not good-looking! It's a world where everyone is equal, where all boys can be playboys! Classrooms, hallways, libraries, toilets, changing rooms, trains...everywhere can be a spot for instant sex!
