Balls tied off untill they are purple. Then the slave is ordered on hands and knees. Nakes anus. The MIstress kneels behind him. She wears a rattling black strapon dildo. And rams it in the slave ass. Now he feels what it is like to be fucked in the anus. Deep and hard! His tied off purple balls dangle on the rhytm of the strapon going in and out of his anus.
