In the dimly lit, Halloween-decorated living room, Cory Chase, Melanie Hicks, and Luke Longly begin a forbidden game of 'trick or treat.' Cory, a seasoned milf, teaches her inexperienced stepsister Melanie the art of anal pleasure, their moans filling the room as they take turns riding Luke's cock reverse-cowgirl style. The taboo threesome reaches its climax with Melanie's first anal orgasm, her tight hole milking Luke's cock as Cory watches in satisfaction.
