Stretching awake, a young man finds his step-sister's head nestled on his lap, her lips wrapped around his morning wood. She sucks him eagerly, her small tits pressed against his thighs. He groans, trying to stay quiet, but her tight lips and wet tongue feel too good. She looks up at him, her big eyes filled with lust, before taking him deeper, gagging slightly. He can't help but thrust into her mouth, her hands cupping his balls. She hums, the vibrations sending jolts of pleasure through him. He warns her, but she keeps going, swallowing his load as he cums in her mouth.
