hey /r/, trying to find an old hentai manga - I remember that the main girl character was sort of silent and had some unquenchable sex drive, and there was some partly colored chapter where she had on a sort of caveman costume and I believe in the second chapter the male protag breaks into the locker room to see what kind of underwear she had and it was some boring striped pair - the art was really distinct but I can't remember the name of the manga or the artist for the life of me
