Mila Lewis, the blonde, pigtailed step-sister, innocently watches TV, but her mind wanders to naughty thoughts. She starts touching herself, fingers slipping into her wet panties, moaning softly. Her step-brother, London Lewis, hears her and enters, finding her in the throes of self-pleasure. He joins in, his own hand stroking his growing erection. They lock eyes, and the mutual masturbation intensifies, until Mila can't hold back, orgasming messily on the bed.
