The vacuum pump is an erotic toy designed to promote an intimate experience. The principle is to use an airtight space that creates a negative pressure around a specific area. Using negative pressure increases blood flow, which can cause increased sensitivity and, among other things, pleasant stimulation. Vacuum pumps are used to enlarge sensitive areas or to achieve more intense erotic experiences.
