The 9 inch King Cock Plus Triple Density Cock with Swinging Balls is made of new and improved Fanta Flesh® material, making it stiff on the inside and soft on the outside. What makes the Swinging Balls truly special is the carefully crafted construction of the stretchy sack and the incredible feel of the firm internal testicles! With every thrust, the balls come swing and slap against the body for added stimulation!
