When my wife wants to make me cum fast she will do what she calls "applying the ball twister handjob". She will take a hold of my balls with her left hand and twist them tight and jack my cock at the same with her right hand and continue to keep twisting them a little tighter all the time. The tightness in my balls and sack and along with the unable to get away feeling and the pressure on my balls is way to much. There is no way that I can not cum once she has this applied and working on me. There has been times when she has made me cum in less than a minute with this technique. She is fully aware that this technique is her finisher on me when ever she wants to use it. It feels like she is going to bust my balls out the bottom of my sack when she has it applied good and deep.
