You'll want more by SexualChoc

Now with ONE finger (the tip of that one finger)
slowly slide your finger up and down the shaft.
Each full stroke stop touching and use the tip of your finger to go up the shaft
in a slightly different spot, try and circle the penis shaft with each stroke
So you stroke the back, little more to the left, left side,
little more front, and so on, all the way around.
Remember use only one finger
and give yourself 50 strokes like that.
