You’re finally a big enough boy to masturbate with step-Mommy. You love watching her stroke her big, thick cock for you and obediently taste her and touch her as you play with yourself. As things heat up, step-Mommy asks you if you think you could handle sitting on it. You’re confident enough to try, and step-Mommy gently talks you through climbing on top of her and taking her all the way inside you. As a reward, step-Mommy strokes your cock as you ride her and brings you to climax as she fills you up with her load.
