Step-Mommy walks in on you watching big booty MILF porn. She isn't upset, but she wants you to use her big perfect ass to jerk off to instead. She begins by shaking her big butt in your face while wearing her checkered workout shorts, spreading her cheeks, jiggling and bouncing inches from you. Soon she pulls them down to reveal her black Calvin thong and proceeds to jiggle and twerk while talking about your big dick and how much you want to fuck her. She's really enjoying this, Step-Mommy pulls off her thong to reveal her tight pink asshole and continues to twerk in your face while encouraging you to jerk off and cum on her round ass after counting you down.
