Metronome to 210.
This is a challenge. I don't think you can handle it.
All the time you look at my pussy, wanting to lick it.
you will stroke fast 3 times and then rest 3 times (1), stroke 3 times, rest 3 times (2), stroke 3 times, rest 3 times (3), etc, etc. This is all done on the speed of the metronome. When you have done this 10 times, you will rest for 20 seconds.
Set the metronome to 180 and repeat all of this.
so, 10 times 3 fast, 3 rest.
rest 10 seconds.
Still there? No edging done? Good!
same thing, metronome to 120.
Same thing, metronome to 100.
If you didn't edge, you earned your point.
