I think you need a break from stroking and edging, I don't want you fucking ruining on me before I'm ready...
Grab those nuts and pull them away from your body as hard as you can while you count to ten.
---
That was kinda fast wasn't it?
Do it again, half as fast as the first time.
---
Better, now squeeze them as hard as you can for a count of ten.
---
If you took less then twenty seconds, do it again.
---
Now I want you to slap your balls, harder than you've ever done it before.
Again, but harder.
Again, harder.
Again... I want you to feel it in your fucking stomach.
Once more, and make this one REALLY count.
