Breaking Superman: Lance Hart (2015)

Superman walks in on the evil Dr. Kincade, and tells him the gig is up. The two struggle and grapple, but in the end the evil doctor gets the upper hand by continuously giving Superman low blows (stomps, squeezes, grabs, knees). Dr Kincade has plans for Superman, but what will they be… He puts Superman in a Kryptonite laced cock ring. His plan is to milk his super sperm out. Superman resists, only to be tormented with more knees, squeezes and pulls to his balls.
