A couple (Nanase Sinon, Horikita Miku, Matsuoka Mio, Misumi Rei) are picked up and challenged to a game of guessing the boyfriend's penis, where they give him a blowjob and get a cumshot in their mouths, but when they fail, they are punished by being fucked raw and creampied by the male actors (Asano Ataru and others)!
