My master rigged up a homemade harness for me to wear. He'll shove a bottle up my ass, fit the harness on me, lock it and leave me, sometimes for hours at a time. The bottle is pushed all the way up my ass and the harness holds it in. And there's nothing I can do about it. When he gets home and removes the harness and bottle, my ass is good and stretched, ready for a deep fisting. Hope you like seeing the anal whore that I am.
