Every slave was once an anal virgin, as was this one before I started training it. I am training it to take bigger and bigger plugs, so that I can have My fun with fucking it in its arsehole. Just so that I am sure this slut in training doesn't wriggle away, I have belted its legs and chained them high above its head. The useless cock and balls are in plain sight, but I'm not interested in them. I am only interested in making this tight boy-pussy looser and easier to fuck on demand: My demand!
