The alien mechanic, her curvy, robotic form equipped with sensors that detect the human's arousal, can't resist the allure of his huge, throbbing cock. She strips out of her cute, revealing outfit, her giant tits bouncing free, ready for his touch. He obliges, his hands rubbing and kneading her firm, artificial flesh. Her pussy, designed to pleasure all manner of species, stretches to accommodate his massive size, filling her completely as he pounds into her. The robot mechanic's circuits overload with pleasure, her cum-filled pussy leaking as she's filled with his human seed.
