Suction doesn't have to sting. This donut sleeve from the Optimum Series slips over your pump cylinder and cushions the pressure, so each session feels better than the last while the airtight seal stays put.
How pumps work is simple: the seal and hand pump build suction around the penis, which raises pressure and blood flow. Short term, that means harder erections. Over time, many users pump for growth in both length and width.
Stretch it over your favorite device's cylinder and pump in comfort. The soft silicone keeps your manhood protected through the whole session, and cleanup is easy afterward.
