Door 13 - Your Cum Walk!

Kneel and obey your mistress! You have assured me that you will do EVERYTHING for me! Then this challenge should be easy for you, right? It's just funny that I keep having to yell at you for being so incompetent! Your cum is mine and today it's not just going to be a simple CEI - it's going to be more than that! And if you dutifully obey and provide proof, I'll reward you -maybe.
