Michelle, her eyes wide with innocent curiosity, watches as her stepbrother, Peter, masturbates in the shower. She can't help but feel a stirring in her loins as she takes in his massive cock, throbbing with desire. Unable to resist, she enters the shower, dropping to her knees, her small hand wrapping around his shaft. Peter groans, his hips bucking as she tentatively licks the head, tasting his pre-cum. Their eyes meet, and in that moment, their boundaries blur, giving way to a forbidden passion.
