"Keep going, stroke that cock up and down for me slave, just how I taught you. So what do you think would happen if I'd snip my fingers right now?"
"P..p..please no mistress"
"Your body and mind should be pretty responsive to it slave, considering how things went down last time."
"P..p..pleaae mistress"
"We'll see about that slave. Go on, nice and steady now with a very light grip. Use the other hand now. And of course no edging without my saying slave. Any slip up today could have very long consequences. If you know what i mean"
"P..p..please"
