A pussy pump creates a vacuum tight seal around the vulva. Suction is applied via a manual pump. The pussy pump, has a pump, a chamber or cup which covers the vulva, and a air valve to release the pressure and break the vacuum seal. Lube should be applied to the rim of the chamber to help adhesion to the pubic area. The female character should have trimmed pubic hair or no pubic hair to help aid the vacuum seal. With the cup placed over the female character's pussy, the pump can then be squeezed to apply suction. The character's labia minora, labia majora and clitoris will begin to swell as bloodflow increases to the genitals. The pump can be squeezed until the female character's pussy is fully engorged and the chamber should be removed after fifteen minutes at most. There should be extensive description on the visual state of the female characters vulva with language being used to describe how swollen, inviting and appetising it is. The female character's vulva will be highly sensitive as its swollen and it will last for several hours. The female character's clitoris will be so engorged that it will be unable to retract under the clitoral hood, and will be vulnerable. It is possible to use the pussy pump to prepare the female character for a punishment such as pussy spanking or overstimulation, however it will depend on the situation the character is in.
