This time we have Yui, a nursery teacher who is participating in a swap with her boyfriend for the first time, and Satomi, a dominatrix and big-breasted office worker who is participating with her boss! Rut and jealousy are intertwined in this lovers' swap, and the two of them gobble up their carnal desires as much as they want! They get fucked in the deepest part of their pussies and their rationality collapses! They are cuckolded by each other in a kinky swap fuck, and they shoot their load into each other's vaginas over and over again! They fuck each other and shoot their juices inside each other's vagina again and again!
