I have tried lots of techniques over the years and have contributed a few times on Solo Touch. But i have just come across a technique that is truly mind blowing. I recently purchased a double cock ring from Anne summers one part goes around the base of your cock the other ring goes around your balls the cock ring has a vibrator piece attached to it.
There are various speeds this can be operated at, whilst kneeling on the bed back against the head board start to use control to put various levels of vibration through your cock ring NO TOUCHING just use this control. Just keep varying the levels on and off high and low (if your fortunate to have your wife suck you off while this is happening thats just totally awesome) anyway keep this going you'll want to touch your cock as it will be so hard now this is the magic bit when you can't take anymore and been 'edging' for as long as you can just before you cum sniff some 'amyl nitrate' poppers we call em here in the UK (totally harmless) and with sniffing this just before you cum you'll have the best orgasm you have ever had I promise. Please comment back after you have tried it.
