Penis exercise masturbator's meaning represents the man to want to be stronger! In addition, we also hope to create some fun during the exercise process. The interior has a special texture that simulates and amplifies various structures inside the vagina, making it more pleasurable. The entrance is made of TPE material for a better experience. Remove clothes, left hand covered with lubricant to tease dick, to make it erect. Cock seems to be pulled, slowly stretching forward,  which helps to prolong your erection time and increase the duration of sex. Click the power button to open the product. Use a special button to change three different suction levels. You can choose the right suction level according to your exercise time. When the maximum suction is reached, press the release button to release the pressure. These exercises can help to create healthy, firm erections. If you think it's too strong, press the button to release the air pressure, which is really safer. This product can be used in two ways: one is to insert the whole penis into the airplane cup, and the other is to insert the head into the cup and feel a strong suction on glans.

Pump cleans easily using warm soapy water or a good toy care fluid/foam.
