His friend's mother is impossibly sexy, with a soft body and enormous tits, and he cannot suppress his desire around her. He has long fantasized about Miki, and one day masturbates while smelling her underwear, unaware that she is watching. Instead of recoiling, Miki becomes aroused and begins touching herself too, but an orgasm from masturbation is not enough. Even with her adult son nearby, she asks for his friend's cock. He knows it is wrong, but he cannot refuse the woman he has always wanted—and keeps pounding her until he has no semen left.
