Finally realized!Best friends and rivals, Hibiki Otsuki and Yui Hatano showdown plan!The two of them, who have been quarreling since the opening, compete for the strong ejaculation of a middle-aged M actor. In front of the four judges, they make an erotic appeal, and when Otsuki blows, Hatano picks an anal.The ensuing game is an ugly battle of deceiving and being deceived (laughs).In the final match, if Otsuki shows riding a crab-like crotch, Hatano will fight back with a standing back!A 4P orgy game that brings out all of each other's eroticism!
