Daddy's girls Kitty and Migi Aoki, both blonde and insatiable, debate the pleasure of a step-sister's ass versus a lifelike sex doll. With Kitty's perfect, big booty and Migi's monster cock, they decide to try both. Kitty fingers her tight, anal-queen asshole as Migi lubes up their sex doll. They take turns stretching each other's asses, Kitty's massive ass bouncing on Migi's huge cock, then his massive tool pounding the doll's tight ass. They switch back and forth, ass-to-ass and ass-to-doll, exploring every inch of each other and their toy. The anal sluts finish by swapping cum, Migi's massive load filling Kitty's mouth from the doll's ass.
