A group of close female colleagues from the company regularly hold a girls' orgy. They rent a hotel suite and invite their boyfriends over for a reverse harem threesome! The boyfriend is suddenly called away and thinks he'll have some quiet sex with his girlfriend, but instead gets straddled and molested by her female colleagues! Claire and Akari, who have genius cowgirl techniques, keep pounding each other even after they've come, forcing them to cum inside of them! Akari's boyfriend and Naoto's boyfriend, who is filming, are both called, and the harem cuckolding continues until the morning!
