A Clitoral Pump — also called Vaginal Pump or Pussy Pump — used as a sex toy is meant for sexual pleasure, and applied on the clitoris, clitoral hood, labia, or entire vulva. Mind that these pumps can also be used medically, for instance, to alleviate orgasmic disorders.
The pump is designed to create suction — the reason why it’s also called a suction toy — which increases blood flow to the genitals. They are sometimes also used for the nipples.
The device normally consists of a cup or cylinder (available in different sizes), which is placed over the intended area, and a hand pump (a type of bulb) with a tube. By squeezing, that is, by pumping the bulb a vacuum is created, which causes throbbing and increased blood flow to the clitoris or labia.
Some pumps also contain certain features for “special effects,” such as vibration options, spikes, or bumps.
