Under the guise of innocent boredom, stepsister Michelle retreats to her room, unbuttoning her blouse to reveal a lacy bra. She slips a hand beneath her skirt, teasing her wet folds with a vibrator. Unbeknownst to her, her stepbrother is watching through the crack in the door, his cock hardening at the sight of her curves. Michelle's moans fill the room as she brings herself closer to orgasm, her stepbrother's breath hitching in sync with her movements.
