Facesitting After A Bareback Ride

It was raining again and I didnt want to do without my rail. Since my slave is not indeed suitable as a climb on, I would rather take my horse again. But I cant saddle it wet. So today I ride bareback. As always, my slave serves as an aid to ascent and is allowed to wait and finally crawl behind me on all fours. I also let him suck the dirt off my rubber riding boots and spurs. Of course, the breeches get dirty and the task today is to clean them for my stable boy. With my tongue, of course, while I sit nicely on his face in my dirty breeches.
