There's a really loooong thread on here somewhere re. self sucking and I've posted to it, but, what the heck, here goes again!
In my early thirties, it just happened that the family was away for the afternoon and I was doing my usual routine of exercise, only this time naked. While doing curls my dick head began flopping on the bar as I took it to the arms straight position and this gave my dick a stir just enough to give me a sucking idea.
Lying on the floor with my head about 6 inches from the wall, I pulled my legs up and placed my feet on the wall above my head, walking my hardon down about an inch from my lips. Trying everyway imaginable to get my lips on the head, I had to be content to encircle my tongue around the knob. With the second circle I shot my load -- mouth, face, eye, you name it, my juice saturated everything below. The exceptionally large climax was one of my best, ever.
Man, had I stayed flexible enough through the years to perform that feat , I know what I would be doing now!
