Kaoru Yasui takes on her first dramatic role. During the three days his girlfriend is away, a man finds the voluptuous gravure model he has secretly desired standing right before him. She tempts him with her huge breasts and asks if he wants to make the fantasy even better. Unable to resist, he gives in despite the guilt, devouring, kneading, burying himself in, and sucking her body before fucking her again and again. Lost in a sweaty affair, they crave each other nonstop, and he repeatedly comes as their forbidden NTR encounter consumes them.
