A mischievous 19-year-old teen sneaks into her brother's room, eager to explore her burgeoning sexuality. She finds him napping, his tented boxers hinting at his size. Gently, she pulls out his cock, gasping at its length and thickness. She tentatively licks and sucks, her inexperience evident, but her enthusiasm grows. Her brother awakens, surprised but aroused, and guides her head, teaching her to take him deeper. She struggles but loves the feeling of being filled, her tightness milking him as she learns to fuck him with her mouth.
