After a shared shower, siblings explore their bi-curiosity in the bathroom, the air still filled with steam and the scent of soap. The woman grabs her favorite dildo, her eyes locked onto her brother's trim, muscular form as he towels off. She teases him, running the toy up her curves, her wetness growing. He watches, intrigued and aroused, his cock hardening. She encourages him to touch himself, and he takes his length in hand, stroking as she slides the dildo into her eager pussy. Their moans fill the room, echoing off the tiles as they pleasure themselves, their gazes locked.
