Donnie Rock gets more than he bargained for when he catches Lexi Luna, his fit step-mom, working out in their home gym. Her toned abs and big tits are a sight to behold, and he can't help but sneak a peek. Lexi, aware of his presence, teases him, mounting the treadmill in a cowgirl position, grinding her tight pussy against it. Donnie's arousal is evident, and Lexi, loving the control, leads him to the bedroom for a forbidden encounter.
