Alison Angel, the all-American girl next door, finds herself in a compromising position as she's caught masturbating by her brother. Instead of being embarrassed, she invites him to join her, her eyes locked onto his growing bulge. She guides his hands to her body, teaching him how to pleasure her, her breath hitching as he hits the right spots. She takes his virginity, riding him reverse cowgirl, their bodies slapping together in a symphony of sin.
