When you need to achieve the size and confidence you have always dreamed of then the Stunt Worx Penis Pump by CHISA is the one for you.

This penis pump uses the power of vacuum suction to instantly give you a bigger, harder erection and can also cause temporary enlargement with the possibility for permanent results if used regularly over time. With each squeeze of the specially designed pump trigger handle, your pleasure rod will grow bigger, thicker, and swell with power.

Once you penetrate the smooth, flexible PVC opening, you will quickly discover throbbing, rock-hard erections that feel great and last and last with no midway performance letdowns! The clear vacuum tube allows you to watch your cock grow, and the quick-release valve relieves pressure with a push of the button. The ergonomic pump trigger fits comfortably in your hand and allows you to operate it single handed, leaving your other hand free for extra stimulation.

How to use the Stunt Worx Penis Pump

  1. Attach the rubber mouth around the large end of the transparent Tube.
  2. Connect the air bulb and hose kit to the opposite end of the transparent penis tube nipple.
  3. Push the center rubber ring in to make it recessed and flat. Apply a small amount of lubricant on the rubber ring’s center rim to allow easy entrance for the penis.
  4. Position the head of the penis against the center rubber ring and hold the penis tube firmly with one hand, while beginning to pump with the other hand.
  5. Pull the pumper handle to pump the air out from the tube, thereby creating suction. Push the air release valve when the penis is enlarges by 3cm (use the measurement scale on the transparent tube), or when no further air can be pumped out of the tube.
  6. Repeat this procedure for 10 minutes once a day, three times a week.


Should the penis curve downward and touch the tube, apply some lubricant on the tube rim to eliminate friction.
Record the size of your penis before initial usage, and measure again every two weeks.
