Busy Fingers

"I want you to watch me masturbate," he said, and we lay down in the bed, side by side.

Usually, I just watch him, my eyes moving back and forth from his hands moving on his slick cock to his face, rapt with concentration. I love to see the changes in his skin and hear his breathing speed up... As I watched I knew I had to touch myself too, so I stuck my hand into the front of my jeans. S was looking at me, at my hand, and I knew he'd want to see what I was doing, so I unzipped and put my hands in his full view, still moving my fingers up and down...
