I'm used to giving myself quick masturbation sessions using whatever is at hand in the bathroom or in the gym shower room, meaning soap or shampoo.
A few days ago I got out the liquid lubricant I use for intercourse with my wife and spread it on my hand. As I gripped and pulled my penis, I added more liquid to the parts of my hand that were not sliding smoothly over the swell of my penis head.
(just below the head, the skin of my circumcized penis is the thinnest and most sensitive to friction)
It was a very satisfying orgasm. I lay on my back and watched myself stroke... with no friction whatsoever, just a slippery grip.
It is amazing to have discovered this website tonight. As I read one story after the next, I lean way back, spread my legs, and I am moving my hand over the swell in my jeans made by my very, very stiff penis,still covered by boxer briefs and jeans... wow. I know I could easily 'go all the way' by just moving my finger up and down and reading the stories.
