The main character is a student and he has a crush on a girl his age. The girl in question is part of a club that does “artistic sex competition” (they do like sex pose and get noted on there technique). She is form a important family in sex art community and he is a nobody with a big dick. She does not like him at the start but they slowly start to like each other (if i remember correctly).
