Hard Riding Pants Facesitting

Ive got a fresh pair of railing pants and after wearing them for riding the first couple of times, Im now going to try them out on the slaves face. They fit really nice, look great and are very comfortable to wear - but judging by the slaves moaning and struggling theyre not that comfortable to have on ones face :-D Not that Id care - I enjoy squishing his face under my butt and smothering him - and he will have to endure it for as long as I want!
