Clitoris Excitement and Enhancement System. The Clitoris Excitement System is everything you need to immediately increase your clit sensitivity, and perhaps increase your clitoris size in the long run. The three included cylinders allow different sensations. Once a cylinder has been put in place and air has been pumped out of it, the pump can be removed, but the cylinder will stay vacuum sealed. This allows the user to keep pressure on a particular spot for extended lengths of time. Applying a vacuum to any spot on the body draws blood to that spot. Increased blood flow increases sensitivity. So using the pump and a cylinder, the clitoris can immediately be made more sensitive. For enlargement purposes the cylinder will need to be worn for longer periods and on a regular schedule. The system also includes on very effective micro clitoris vibrator, so the user can take advantage of their now more sensitive clitoris. Category: Size Matters, Female Pumps, Enlargement Gear.
