I use the slave's mouth for my pleasure and for that he must really suffer! I start off nicely, because first I sit down on his face with my hot ass so that he can hardly breathe. The slave still thinks he's in heaven! But don't worry, he'll soon get over that. He has to take first my high heels and then my feet in his mouth and suck them. As motivation I spit on him and spit pre-chewed food into his mouth. Finally, he has to swallow my strap-on until the food I've chewed almost comes up again!
