Chisato comes to share the room with lesbian couple Yui and Mio. Yui senses a kindred Yui in Chisato, who is much older than her, and they get to know each other by French kissing and licking each other's bodies, then they have lesbian sex where they make each other cum with cunnilingus! After that, Chisato also becomes aroused by Mio and makes a move on her... When Yui finds out, she punishes her with a lesbian threesome. After Chisato has her big ass spanked and her tongue sloppily sticks out, she serves the two with a double fingering, and then gets made to cum over and over again by the two girls, who are almost young enough to be her daughters, in a three-way cunnilingus session!
