Crushing His Mouth Under Riding Boots

I trample the slave under my sexy - but very painful - full leather railing boots. But today Ive planned something a little bit different - a little bit more brutal :-D I want to trample the losers mouth under the hard feet of by boots! I thrust his head down with the boot and then shift my entire weight on his mouth. I also walk over his mouth a duo of times - but this loser cant keep his head on the floor like I ordered him to! So I will stand on his throat even longer! Sometimes I also stand on his throat with on boot while the other boot stands on his face - and of course I still trample his chest in between as well - I dont want him to get any rest in between!
