There's a group of hotties known as the Guilty Seven at my college. I, Roka, have a crush on one of those guys, Shun. One day, I stumble upon him having sex with a girl on the roof. The president of the student council, Tenma, catches me taking photos of the guy I like getting it on...! In exchange for not handing me over to the police, I have to sleep with and collect photos of the Guilty Seven climaxing... even though I'm still a virgin!!
