We came across a gal and her virgin brother in the street during a survey of siblings, and asked them to take her virginity for a mission that would earn them 100,000 yen per shot! He unexpectedly ejaculates when he inserts his penis in the cowgirl position! His virile dick can't be satisfied with just one ejaculation, so he cums inside her again and again! I thought there might be more to come from these two, so I gave my brother a camera and had him film them! This is a video recording of their daily lives, where they smoke in the room, cook with their family, talk about love with their boyfriends and friends, and have raw sex everywhere!
