Ambitious BBW instructor, eager to prove herself, takes a chubby student on a practical lesson in her car. She's in charge, pushing her thick thighs wide to straddle his lap, her massive tits bouncing as she grinds down on his hard cock. The public setting only intensifies her desire, and she eagerly sucks him off before riding him reverse cowgirl, her big ass jiggling with each thrust. She takes his load on her face, smiling at the passerby's curious glances.
