Used either as a suction sex toy or an erection enhancer, this deluxe penis pump comes equipped with a gauge to ensure that just enough blood is pumped into the penile tissue.
 

Put some lubricant on your penis while aroused and insert your penis into the chamber. Use the trigger pump to vacuum suck at your erection, then place the adjustable snapped cockring at the base of the shaft and remove your plump erection!
