How long does my saddle last under my ass?!

Description: Today i want to train this loser to be a good saddle for me. a good saddle obviously has to hold up for more than just a few minutes and a saddle isn't used with caution! again and again, i sit down on the slave's face with my riding pants and enjoy the feeling of flattening his face under my ass. after a while he always starts to moan and struggle, as the oxygen supply runs out ... but i'll only allow him to breathe shortly before i sit back down. sometimes, in his breathing breaks, i slam my butt onto his abs as well to make his recovery even harder. and of course, i brought my riding crop ... just in case i need it to keep my saddle in line!
