Slave pinned down and smothered

Description: I pin down the slave on the floor, fixating his hands under my knees - so he can't get up or even try to fight back ... and then i smother him with my hands! i press my hands firmly over his mouth and nose - making sure not the tiniest bit of air can get through - and only i decide how long he won't be allowed to breathe. sometimes, i let him breathe in between, but sometimes, i keep his mouth shut and let him only breathe through his nose ... not long enough to fully recover obviously! later, i sit down a little lower and pin his hands down with my boots - also a very comfortable position for me - while smothering him ... but this loser really can't hold his breath for long ... i think we need to extend his training!
