Assume the position on the couch, submissive one, as I replace your ass with my fist. Witness the ease with which my hand enters, yearning for more as your ass gets stretched. Now, open your mouth wide. I will defecate into it. Ah, the aroma is enticing. I will now fill your mouth with my feces and force it down your throat with the help of a strap-on. Chew, swallow, and savor the lesson, my dear submissive. I will train you to relish this very act of consuming feces.
