In the backseat of the Uber, my mind raced as I tried to retrace my steps. The driver, a muscular Latin man, watched me in the rearview mirror. 'You look tense, mami,' he said, his voice deep and soothing. He pulled over at a deserted park, turning to face me. 'Let me help you relax.' His hand reached for my thigh, sliding up my skirt. I gasped, my pussy throbbing. He unzipped his pants, revealing a massive, hard cock. 'Ride me, mami,' he commanded. I straddled him, my big ass slapping against his thighs as I rode him hard, my loud moans echoing in the night. My pussy gushed, squirting all over his cock and the car seat. He grunted, his cock pulsing as he filled my pussy with his hot cum, my big ass dripping with our mixed juices.
