To get one of the best feelings ever out of wanking, you have to try wanking with a cucumber.
I take a cucumber and scoop the inside out with a teaspoon. Sometimes I may have to make a cut down the side in order for it to fit around my cock. I then put it into the microwave for ten seconds just to soften it.
Next, I cover my body and cock in lube so I'm nice and smooth-it feels awesome to rub your hands around your lubed up body.
I then put the cucumber back into the microwave for twenty seconds so that its not soggy, but still warm enough for jerking with. I then lie down and jerk for about an hour and then cum while still using the cucumber. It's nice because some of the cum stays in the cucumber and the rest shoots onto your smooth body. I then like to rub the cum into my greasy body.
I've been using this technique since I was 14, five years on and it still makes me horny.
