Ok slave, stop stroking and squeeze your ball sack as hard as you can.. Keep doing it.. Harder!! Crush those useless balls bitch!
Stop! *Grin* Did you enjoy abusing those cum filled balls for your mistress? Let me hear you say it! Your a bad stroker boy who just craves my abuse dont you, you get off on it dont you!?
Put some icy hot on your balls and start to stroke really fast again. I want you on the edge of cumming, quickly now, i dont like waiting around for losers. Once your as close as you can get, stop and spank your balls hard 25 times with your ruler.
From now on, when i tell you to do an edge, this is how your gonna fucking do it. Do you understand me? Imagine that every time you get to the edge, i am standing over you, kicking those pathetic little prunes with my sexy high heel boots.
