Shane steps into the bathroom, unaware of his girlfriend's lurking presence. She pounces, pushing him against the wall and unzipping his jeans. His cock springs out, hard and ready. She licks her lips, her eyes gleaming with lust as she takes him into her mouth, sucking and slurping noisily. Shane, caught off guard, can't help but groan in pleasure. His sister, hidden, watches with fascination and envy, her body aching for similar attention. The scene is raw, primal, and full of forbidden desire.
