That was pretty good for a first try, slave. I'm not sure it would convince Mark though. You'll have to fake it much better when he's fucking you. You'll have to practise. If he doesn't truly believe that you love it when he pounds you, he might not be happy. If I hear any bad reports about you, you WILL be punished, understand?
Good.
Now stay on your hands and knees and kiss My feet. I want you making out with them like they were the love of your life. French kiss the toes, show me how passionate you can be!
