The stepson arrives just as they are getting ready for bed and complains about the terrible heat in his room, saying he can’t sleep there. So his parents are forced to let him in. He stands between them, facing his mother. He touches her gently, brushes against her, and little by little his penis grows. The mother notices but pretends not to say anything; she doesn’t want to seem perverted or betray her stepson to her husband, but the truth is, she is getting increasingly aroused. There is a moment when her husband leaves the room without realizing what is really happening, and it is at that moment that the stepson thrusts his penis deep inside her, and she still says nothing. Everything spirals out of control; the thrusts continue, she begins to moan uncontrollably, and when her son tires of thrusting into her, she ends up masturbating him, until he ejaculates all over her breasts.
