I brought along a stopwatch to train this loser's smother endurance today. I sit down on his face wearing my tight grey jeans and smother him under my ass while stopping the time. How far can I push his limits?! Of course, I'll only give him short rests in between - too short to really recover and get the oxygen saturation back to normal. The slave moans and struggles under my ass as I flatten his nose and smother him, but that's not going to help him - he'll endure this training for as long as I want him to!
