Wow, nice work slave! Only a handful of male slaves in the entire galaxy could manage that, and most of them aren't here or haven't made it this far.
For your last task, I want you to keep that weight attached to your balls and make it dangle in the air once more.
You are to take a dildo and deepthroat it until you gag 10 times. You may not lessen the weight on your balls until you have gagged at least 10 times on that dildo.
When you've done that, you may sit down only if you do so on the dildo.
