Drunk and horny after a wild night out, a sultry step sister stumbles into her stepbrother's room. She's dressed to kill in a tiny dress and heels, her makeup smeared from the night's debauchery. She doesn't bother with foreplay, instead, she straddles him, grinding her wet pussy against his growing bulge. He's hesitant at first, but her aggressive moves soon have him rock hard. She unzips his pants, revealing his throbbing cock, and slides down onto it, riding him like a bucking bronco.
