More rigorous mouth and tongue training. Perhaps just showing this image to your slave will convince her to keep her mouth open and her tongue extended!
I’m going to destroy your fucking tits and stinky cunt.
The best kind of girl is a literal and sexual doormat.
Have her sister lick it clean, and then use that dirty tongue to eat the doormat’s ass While you hatefuck both of their cunts. Wipe your cock clean in their hair, and send them down to the foot of the bed, just where they belong.
What a lovely footprint.
