A 4-hour incest film between a mother and son. The mother, without her husband's knowledge, stuffs her son's dick into her mouth, sucking and drinking his semen with both the top and bottom of her mouth, never letting go of his raw penis, which is younger and stronger than her husband's. The son sucks and rubs his mother's breasts like a child, making his penis hard, and then, like a male dog in heat, he swings his hips vigorously and ejaculates deep inside his mother's vagina. The mother and son are truly excited by the taboo raw sex.
