Young and eager, she takes in the sight of his massive member, already rock hard and throbbing with desire. She tentatively wraps her lips around the head, her tongue flicking out to taste the precum beading at the tip. He groans, his hands tangling in her hair as she begins to suck, her head bobbing rhythmically. She can feel his cock pulsing in her mouth, and she knows he's close. But she wants more. She opens wide, taking him as deep as she can, and then she does it - she bites down, not hard, but enough to make him gasp. His cock jerks, and he comes undone, flooding her mouth with his hot cum.
