William Seed is a horny stud with some issues controlling his sexual urges. When sexologist Ace Quinn finds William in his waiting room stroking his big cock, he immediately understands why the burly blond stud has come for an appointment. Ace tries to determine the cause of William's compulsive penis by teasing William until he can't take it anymore, begging the big fit doctor that I can climb on him. Ace rides William's huge cock, letting him touch his sheath as the brown-haired stud moans in ecstasy. Ace takes the full force of William's big roll until the end, both of them driven by each other's abilities. William covers his glasses using the doctor's face with a thick, creamy load that has them both gasping in this intense scene.
