Fuck your man, your hand, or your stroker with a cock that bulges with hardness and sensitivity.
Lube up and slide your cock through the tight seal of the silicone sleeve into the cylinder. The grooves along the outside ensure that you can maintain a firm grasp while your cock grows inside. The hose leads to a trigger handle that is easy to operate. Just squeeze and pressure will build inside the cylinder, drawing blood flow into your dick for increased size, stiffness, and sensitivity.
Once you're satisfied with your gains, use the pressure release valve to free yourself from the intense suction. Your cock has never been more fun to play with!
