Brutal Breath Training Under My Arse

Today the slave will have to bear a brutal breath training! Ill sit down on his face and stay sitting longer and longer each time. But well begin leisurely... 20 seconds, then 30 seconds, then 40 seconds - that wasnt too hard for him. Lets see if he can treat 50 seconds with my gams extended over his bod and my full weight resting on his face! This time the slave is struggling and shaking the last few seconds under my ass - but hell have to endure even more! Next, he has to hold his breath for full 60 seconds - and he gets through them as well - maybe hell make a good human seat pad after all :-D Lets see what happens when I keep sitting 70 seconds!
