Marilyn Johnson's boxing class takes a kinky turn as she and her trainer get down and dirty. She starts by licking his cock, then engulfs it, gagging and choking as she takes it deep. They move to face-sitting, Marilyn's soaking pussy rubbing all over his face while he pounds into her from below. She rides him in cowgirl, her sweat-drenched body writhing, before they switch to reverse, her tattooed back arching as he drives into her. The trainer then pulls out, covering Marilyn's face and tits in his hot cum, leaving her breathless and spent.
