Full Stroke

What I like to do is get my hard cock all lubed up and start rubbing the underside of my cock head. Then I start stroking my shaft the whole length and make sure to get the edges of the head. The combination of stroking and stimulating the head feels so good and when I'm about to cum, my head gets swollen which makes the edges of the head more sensitive and bigger. When I do cum the head gets sensitive but I power through it and keep stroking and send shocks through my body to where I have full body twitches. I then continue to see how long I can take of the sensitivity after I cum and produce an amazing feeling afterwards.
