Total Obedience
"And now that you're being reminded of that I want you to start stroking. I think it's time to fill those balls up again for me. Getting them nice and swollen and blue... Go ahead, wrap your hand around it just like loosely and go up and down"
(You start stroking)
"You’ll stroke in whatever way i choose from now on. There won't be any more room for any of your mistakes tonight, clear?."
(You nod your head)
"Good, then keep your back straight and your head up while you jerk slaveboy. Go all the way up and all the way down your shaft. Again, no more slip ups from here on out slave!. Do we have an understanding slave?"
(You nod your head heavily)
"I hope so, i really do, otherwise this could turn into a very unpleasant experience here for you. I know a thing or two about making a slave wince in pain, how to let his cock and balls suffer. You know, i could make your dick and balls hurt so much so that it would wake you multiple times throughout the night and you'd have to ice them slaveboy. You don't really want that, do you slave?"
(You shake your head)
"My oh my look at you, you're quivering. Someone seems to be getting a little aroused. Well, you better not be getting close already, wouldn't surprise me though. Keep going at that pace, maybe you can do something right for a change, that'd be nice..."
