I know you want to jerk off every time you see your Mistress. I bet that nasty little dick is already twitching with anticipation. It's all you can think about - watching Me, stroking your worm. Am I driving you crazy yet?
If not, then I'm about to. I'm going to let you stroke, but only when I say. I want to play with you. And when I play with you, I'll tease you so much that your balls will be aching and you'll be crying tears of desperation.
Only then, will I allow you to cum...
