Right tie the vibrator back to your cock, and set it to full speed.
I want to see you squirm so
edge, ride it for 30 secs, then you can turn it off have 1 minutes rest.
Back to it slave, do the same again but with only 50 seconds rest
Then its 200 fast strokes, and you better be on the edge at the end, hold it for 40 seconds
Get the vibrator back on fast again, back to the edge and hold till i tell you otherwise
