A lanky, smooth-skinned teen enters his sister's room, finding her oiling up, her perky breasts barely concealed. She offers a massage, and as he lies down, she pours oil onto his back, her hands slowly sliding down to his hips. He tenses as she reaches his cock, but she persists, wrapping her slippery fingers around his hardening shaft. She strokes and rubs, her other hand cupping his balls, milking him expertly until he cums, his body convulsing with pleasure.
