With your thumb and index finger, grasp the loose skin just below the head of your penis like you would if you were going to gently pinch it. Now begin sliding your fingers back and forth, like you might if you were feeling the texture of a piece of cloth. It may start slow, but the orgasm should be strong and sudden.

Feels Good
I am fairly new to this site ( wish I'd found it long ago ). I am uncut and find that using this technique on my foreskin results in a feeling that is very satisfying . It doesn't take long for the pre-cum to flow and then I go quicker until I reach a strong orgasm.
Uh sounds great
I would love to jack you off and fulfill any fantasies you might have. I'll be fingering my hot and wet pussy thinking of your dick
