Dr. Riley Nixon, clad in her crisp white coat, greets Vanessa Vega for her routine check-up. As she examines Vanessa's ample, jiggling ass, Riley can't help but feel a twinge of lust. She begins to probe Vanessa's tight, virgin asshole with her gloved finger, slowly working her way in. Vanessa moans, her pussy dripping with anticipation. Riley, unable to resist, plunges her fist into Vanessa's ass, stretching it wide. Vanessa cries out, her massive tits bouncing as Riley pounds her relentlessly. Suddenly, Riley grabs a strap-on, thrusting it into Vanessa's pussy while continuing to fist her ass, giving her a brutal double penetration.
