Use this pump to increase blood flow to your most sensitive regions. Simply adjust the cylinder so you can get a tight seal around your vaginal area. A high level of pressure will be required to get a good seal. We also recommend a good water based lube to help create that necessary seal to get a successful pump. Easy to use, place the cylinder over your desired erogenous zone and squeeze the pump to draw blood into the area. You will feel suction as your clit increases temporarily in size and sensitivity. You can easily release the pressure in the cylinder by pressing the release valve on the bulb. You can also detach the industrial grade acrylic cylinder from the pump with the simple clip system, leaving your clit suctioned up in the cylinder. The kit will have 1 pussy cup, 1 hose and 1 rechargeable pump. Compatible with all types of lubricant.WARNING: Please read product manual before using any type of vacuum pump.
