You're about to experience one of my favorite torments, slave.
But before... you know, I just can't resist. You have such a cute little subby butt. Why don't you pop the inflatable plug in and pump it however many times you want?
Good bitch. Now, once your balls are a little warmed up, wrap them up in that shoelace again. There should be a good amount of slack. Take the bottle with water in it and tie it to the end: the bottle should rest on the floor while you're kneeling.
Mm, you make such a pretty picture.
Pick up the bottle and stand (don't let it tug on your balls). Now, put it on a desk or other waist-level surface behind you. I want you to stand far enough away that there's a little bit of slack.
Now, slut, lube up your hand and wrap it around your cock.
Until I instruct you so, you're NOT ALLOWED to move your hand. Now... how many times did you pump that plug? Subtract the number from 15. WITHOUT moving your hand, you're going to edge for me THAT number of times, just by thrusting your hips. During each go, you should hump your hand fast enough to pull that weight off of the desk! Once it's off, you have to hump as fast as you can until you're on the edge, and stay there for 1 minute!
Take a sixty-second break between edges, and put the weight back up. If you get to the edge without pulling the weight off the desk, it doesn't count!
Aww! At least you have a nice view - right?
