As my slave, you need to know how to serve all my guests - the women and the men. I expect you to serve with enthusiasm and a high level of skill. I have exacting standards so we'll need to begin your training now. I know you've never had a dick in your mouth before, but in my employ you'll need to know how to suck cock like a pro. You know what they say; practice makes perfect! I've procured a few training aids to help you learn to suck the real thing. You'll be on your knees with a plastic dick down your throat, drooling and gagging until I think you're ready for the real thing...
