My wife traveled alone. As the couple's relationship cools down, she can no longer stand the temptation of her wife's younger sister, Yuki. "Anyway, sister... she's having an affair while traveling..." Her reasoning is blown away so much that she thinks it's no good... Day, night, and morning, while her wife was away, she repeatedly had intense sex with Yuki, and she ended up vaginal cum shot over and over again... Her immorality was too pleasant... .
