Description
Battery operated vacuum pump specially designed to enlarge the head!Before use, we recommend applying a little water-soluble lubricant to the head. Then push the head into the cylinder through the expandable opening of the sleeve and turn on the pump with the on/off function. The suction suction function will start immediately, accompanied by pleasant vibrations. Due to the negative pressure produced, the head can swell like a bullet, quickly becoming bulging and thick! The push button can be used to dose the vacuum according to your own comfort and needs. Expandable sleeve with small stimulating nubs.
