Cute Mary, the step-sister, teases her brother with an oil massage, her small hands gliding over his chiseled body. His massive cock tents the towel, and she can't resist taking it out, stroking it gently. She jerks him off expertly, her pace quickening as he groans. With a final few pumps, he erupts, coating her perky tits with his hot cum. She smiles, wiping it off sensually.
