Pumping Air into Penis + Back Massagers

I have done something amazing more times than I can remember, using a Water Pik without the water to pump air into my penis and my bladder. The pressure is not so high as to injure, just don't over do it or get too full. Another variation that is mind blowing is to use the Water Pik with two high power back massagers. In a sitting position, put one massager beneath your testicles against your prostate. Put the other one on the underside of your penis. Have the Water Pik ready, and when you get within a few seconds of orgasm, grab the Water Pik and start pumping air into your penis. Its like a game of tug of war, your body goes into an extra gear trying to fight the air and let you ejaculate. You can see your penis expanding as the pressure builds. Eventually as you keep orgasming the pressure and sensation builds until you can't take any more and need to release and you have to remove the Water Pik and ejaculate. It is mind blowing, I have lasted almost 3 minutes in that mid orgasm tug of war at times. Just make sure the Water Pik is sterile and this will blow your mind.
