That's it slave, though I think you could have gone for a bit longer. Now you see these heels I'm wearing? Stay kneeling, I'm going to force one down your throat.
Take the spike of a heel and push it all the way down your throat. Hold it there until you gag, and then put it back in until you gag again. If you can't gag, then your heels aren't long enough and you need to purchase a new set as soon as possible.
