In the throes of pre-wedding jitters, Penelope Kay's stepbrother, Chad Alva, finds an unexpected comfort in his stepsister's arms. Penelope, with her luscious body and insatiable appetite, offers her tight pussy as a distraction. She starts by swallowing his massive cock, her big tits pressing against his thighs. Then, she mounts him, her big ass grinding against him as she rides him in cowgirl, missionary, and doggystyle. Their taboo fuck session continues until Chad's pent-up stress is relieved deep inside his stepsister.
