self pleasure
I like this one, partly because it reminds me of how I was thinking about how you, the viewer, would be watching me while I climaxed. And wanting me to do it. And the shiver of excitement that thought gave (and still gives) me. I also like remembering the feeling of my fist tightly clutching my cock as it pulsed, throbbed and shuddered in my climax - and how it went on and on. And then the follow-on pleasure of sliding my cum soaked hand up and down my cock. So smooth and warm and satisfying.
