Brought home by her father, 18-year-old angel-faced newcomer, Lily, seems innocent enough. But beneath her halter top and denim shorts, she's a raging hormone, sneaking into the bathroom for secret self-pleasure. Unbeknownst to her, her stepbrother, Jake, watches through a crack in the door, his cock hardening as he spies her wet, pink pussy. Unable to resist, he joins her, their taboo tryst turning from innocent touches to deep, passionate kisses and mutual masturbation.
