My girlfriend's curvy stepmom gives me a deep throat blowjob in private

My girlfriend\'s stepmom is a busty vixen with a massive ass and killer curves. When we\'re alone, she can\'t resist giving me a deep throat blowjob. Her huge tits are a bonus, but her skills in the bedroom are what truly set her apart. She loves to ride me cowgirl style, and when I take her from behind, her ass bounces with every thrust. It\'s a taboo fantasy come true.
