Two innocent-looking teens, barely legal, find themselves in a compromising position. Cornered in a small room, they decide to make the most of their predicament. The boy, hard as a rock, can't help but stare at his sister's perky tits straining against her thin shirt. She notices his bulge and, with a mischievous grin, drops to her knees. She's never done this before, but she's seen enough porn to give it a try. She pulls down his pants, revealing his massive cock, and tentatively licks it like a lollipop. He gasps, encouraging her, and she takes him into her mouth, sucking and bobbing her head, determined to make him cum hard.
