Mellanie Monroe, the sultry MILF, is back on PervyMother.com, this time giving her step-son Tommy Wood a fitness lesson he won't forget. In the dimly lit gym, Mellanie's tight sports bra struggles to contain her ample cleavage as she demonstrates squats. Tommy's eyes linger on her ass, making her smirk. She catches him staring and decides to give him an extra workout. She guides his hands to her breasts, then helps him strip off his shirt. They fall onto the mat, Mellanie straddling him, grinding her hips. Tommy's cock tents his shorts, and Mellanie helps it free, riding him slowly, her moans echoing in the empty gym.
