Easy squeeze trigger action ensures perfect results every time, just pump to your comfort level and use the quick release valve on the pump if you want to relieve the pressure. The silicone air hoses also have on/off valves so you can adjust the suction on both at the same time, or only on one side if needed to get your perfect level of suction! Use during solo play or with a partner to enjoy the most intense sensations and heightened orgasms!
