Mio, my wholesome and devoted adult college girlfriend, has only just moved to Tokyo when men at a club party notice how large her breasts are and fix their eyes on her. The experienced party boys force drinks on her, and she awakens to find them groping her. Surrounded by men far stronger than she is and hopelessly outnumbered, she is made to drink, fondled and fucked over and over. I can only stare in shock as she gradually changes, gives in to the pleasure and is completely conquered by the group.
