On the Toilet
One of the techniques I frequently use is to sit on the toilet, lean right forward placing my left hand on the floor and then lift my feet off the floor. I am therefore now straddling the toilet whilst jacking off. I find that I can effectively buck my right hand. I get to climax more quickly and more intensely than simply jacking off. I did this the other day whilst my girlfriend and her sister were outside the bathroom door-little did they know what was going on on the inside!
