I told My slave to train his asshole every day for a few weeks until I finally decided to give it a try and see how much I could fit in his little hole. I restrain him in the Boomer bondage chair and put a rubber gas mask on him, letting him breath in slowly... Then, gloved in black shiny latex and starting with just one little, I start drilling his hole more and more, until all My fingers are inside him and My fist slides in. I proceed to alternate both hands, both fists. Listen to him moan while I stretch his greedy hole! Director, producer, DOP and editor: Mistress Firewolf
