Bored and curious, a stepsister sneaks into her brother's room, finding him asleep. She can't help but admire his growing bulge. Gently, she unzips his pants, revealing his hardening cock. With a mischievous grin, she takes him into her mouth, swirling her tongue around his sensitive tip. Her brother awakens, surprised but aroused, as she sucks him off enthusiastically, her head bobbing up and down.
