The woman is on her knees, eagerly taking the mechanical dildo in her mouth. She licks and sucks it, taking it in as deep as she can go. The dildo thrusts in and out of her mouth, making her gag and choke. She eagerly accepts the challenge, pushing herself to take more and more. As she sucks, her hands wander down her body, caressing her breasts and stomach. She moans and groans as the dildo continues to thrust in and out of her mouth, filling her with pleasure and desire. Suddenly, the dildo stops moving. The woman looks up, confused. She sees a button on the side of the machine and presses it. The dildo starts to vibrate, sending waves of pleasure through her body. She rides the vibrations, moaning and groaning with pleasure.
