My, what a good boy you are!
Remove the butt plug from your ass and lube up the dildo.
Get down on all fours.
Watch as I enter Bitch's pussy, and slowly slide the dildo into your ass--just the tip.
Now, pause as your asshole feels the girth of the dildo. Imagine that it is your mistress who is about to fuck your boy pussy.
DO NOT TOUCH YOUR COCK!
Hold the tip of your dildo in your asshole for 2 minutes before continuing. Relax. You're about to go fuck yourself.
