After his older brother and sister move out, the family turns their empty rooms into a vacation rental. One day, his parents leave their adult son in charge while they take a trip together, with three women booked to stay that day. He assumes he can handle a few grown women on his own, but the guests turn out to be three outrageously sexy, insatiable mature women. They immediately launch into lesbian threesome sex, catch him peeping and punish him by playing with his cock, then barge into his bath. In no time, the family home becomes a festival of lust. If his parents do not hurry back, they will find their son's balls completely drained.
