Bruninha, the horny, fit milf, is back at the gym, but this time she's not alone. Her student, eager to learn, watches as she stretches, her overalls hugging her ass. She turns, noticing his gaze, and a wicked smile spreads across her face. She approaches, straddling him, and begins to 'train' him, her ass bouncing on his lap as she rides him in doggystyle, her pussy clenching around his cock.
