Rock Hard

What I do is I look at porn or something and start to get hard. Then I make the OK sign with my hand and get a firm grip around the base of my cock. Not so hard that it hurts, but a good grip. Then I flex my PC muscle (the one between your balls and anus). This pumps blood into my already hard cock. With the grip, none comes out so before too long my dick is an inch longer than usual and it is completly engorged. Then I lube up and go to it. It feels great. You're gaurenteed to explode!
