Mathias, a chubby twink with a thick, uncut cock and a mop of brown hair, finds himself in a private lesson with his old, silver-haired teacher. The teacher, with a knowing smile, guides Mathias' large, veiny dick, showing him the pleasure of hairy, gay masturbation. The teacher's own cock, hard and leaking, presses against Mathias' thigh as he demonstrates the perfect technique, leaving the young twink gasping and ready for more.
