I've decided you can serve me better in a different form. You claim to be completely dedicated to serving me and pleasing your Mistress, and I want to test that. I'm going to turn you into my little toy - a buttplug to be precise. If you're lucky I might use you myself one day, the ultimate treat for an ass worshiping slave like you to be placed inside your Mistresses asshole. More likely though I'll be putting you to use as a butt plug for my other subs. Hold still. This will only tickle for a second... wait until I show you your new appearance in a mirror. Quite the improvement, I think.
