Right, you're making a mess here. Put a condom on, and lick up any precum you may have spilt on your hands, the floor, wherever.
Put whatever you're using as a dildo back in your mouth, and show it some love.
You may now orgasm, but don't you dare stop sucking. I want it clean.
Now. I know what you want to do now. You want to stop. You want to go back to whatever pathetic shit you normally get up to on your own. Well don't. Remember how badly you wanted to be my slave? I don't want to have put you through all these trials for nothing.
Take your condom off, tie a knot in the top, and put it away under your bed and leave it there. Get your little sissy-stick all cleaned up, and come back.
