Lady Sara Borgia's slave still wants to be let out of chastity for the weekend. I guess he never learns, well if he wants some sexual activity then his kind Mistress will let him have some...

With Her black bitch and his big black cock.

Lady Sara soon has then sixtynining and sucking each other's cocks. Her slave gagging on the big black cock he has to suck. For some final humiliation Lady Sara makes Her slave kiss, lick and worship Her black bitch's ass. Hopefully he learnt that the only person who gets to have fun is Mistress.
