I have my slave on the floor waiting for me. I told him he must not touch his cock until I allow it. I found him playing with himself, so I decide to give him some assistance. I have a length of twine that I'm going to use. I sit on top of him so he can't move. Then I tie the twine tightly around the base of his cock and balls. Giving it a good tug to make sure it's knotted properly. I then tightly wrap the twine around his balls until they swell and turn a nice shade of purple. This causes my bitch to squeal. As I tug and pull the twine tighter and tighter, it looks like his balls will burst. What a thought? Unwinding the twine from his balls, I stand up while at the same time give it a good tugging. Then I press my foot and stiletto into his purple balls to make him squeal even more. I then secure his stretched cock and balls, by tying the twine tightly to my bench. He's going to have a painful day until I return...
