In the dimly lit bathroom, Maria's soft moans echo as she delicately explores her slick folds, her fingers dancing around her clit. Unbeknownst to her, Will has been watching, his cock hardening at the sight of his sister's secret pleasure. He steps in, startling her, but Maria's surprise quickly turns to desire as she sees his thick, eager cock. They lock eyes, the air thick with tension, before Will steps closer, his hands replacing hers, making Maria gasp with pleasure.
