It was supposed to be a trip for the father, stepmother, and son. However, due to an unexpected turn of events, it ended up being just the son and stepmother. The son was conscious of his stepmother's big tits and big ass, and he got an erection when he saw her peeing in the field. When they arrived at the inn, he forced her into the bathroom, had her wash her body, and had her suck his penis. The inn owner filmed them, and the son witnessed her being threatened and raped, and became aroused... A perverted fuck trip for the son, who swallows his mother's saliva and fucks her like crazy.
