Hey again my little chastity wanker. Today is another stroke day! We are
 going to play a really fun game. But first, I need to cover up, you 
just don't deserve to see your Mistress like this yet.
I'm going to let you out of your chastity and you will be allowed to 
stroke your cock but only in 5 second increments! After I count down 5 
seconds on my hand, you must remove your hand from your
dick. Then when I begin counting again, you may continue jerking off. 
You won't be allowed to cum until I say and you must cum immediately or 
you won't be allowed to cum at all! I could count down
twice or a hundred times. I wouldn't screw it up if I were you because 
who knows when the next stroke day will be! Are you ready to begin? Here
 is your key. Unlock your cock and I'll start counting
down! Don't worry, I'll give you some visual stimulation as needed. But 
don't you dare get too excited or you might cum too quickly!
