I patted my slave-slut niece's head as she sucked my cock clean. Her skills could still be better, but she made up for it with her eagerness to please. She now seemed a completely different person from the snotty spoiled bitch she once was. Perhaps it was a good idea to invite Amanda over after all. As long as the slut behaves, she'll be spared the harshest tortures. I'm sure I'll still enjoy tying her up, whipping her and using the clamps on her, and I'm sure she'll learn to like them too. If she misbehaves, I'll bring out the needles and the branding tools again, and there's someone who'll always be eager to help me use them on the delicious body of my naughty slut of a niece....
