He fucks his own mom while dad sleeps in the same bed

This guy has a masturbation addiction problem and the doctor told him that he should cut it off with women. So what he does is go in the middle of the night to his parents' room and start putting his hand on his mother until he cheers up and sticks his dick in her pussy. The mother is scared, but in the end she lets him have sex with her, even though she knows that her husband, the father, is sleeping next door. The son fucks his own mother and enjoys every second he has his cock in the pussy.
