Ma demi-sœur m’a trouvé en train de me masturber, mais elle était tellement excitée qu’elle m’a sucé la bite jusqu’à ce qu’elle me fait jouir

My stepsister sees me masturbating, apparently that made her very horny, because instead of giving me away, she helps me with my happy ending. She gives me the best cock sucking I've ever had and manages to make me cum very delicious.
