Denied and Frustrated by the Edge-O-Matic 3000 - Edging Tease & Denial

I'm loving my new Edge-O-Matic 3000. It does all the work for me, and I don't even have to do a darn thing.. All I have to do is tease and taunt slave while he gets edged over and over and over again by my machine. Unable to cum - no matter how hard he tries. So what can I do to frustrate him even more? Sit on his face and make him smell my dirty ass of course. He's been trained to become aroused to the smell of my asshole, so this just adds to his torment and gets him to the edge even faster. He even gets to smell my stinky stockings for a few minutes too that I wore with my nasty sneakers to make them nice and fragrant just for him.. I know he wants to cum so bad, but I'm not going to let him, and the machine isn't going to either. It's so much more fun to deny. After 30 minutes the Edge-O-Matic ends up denying him 80 times! I'd hate to be him hehe
