The Human Saddle’s Stamina Test

This slave bragged about being able to hold his breath for a long time - so Ill put this to a test. Lets see if he could serve me as a saddle for a long rail! Obviously... since hes supposed to be so bearing... he will not get long rests in inbetween! He starts to fight after a while - but now hell have to suffer it. He shouldve thought about that before bragging so much - now Ill of course shove his thresholds even further. I sit on his face with my full weight with my gams extended over his assets as well!
