Mistress fucked the slave's ass to the anal hole at a photo shoot

The mistress has been engaged in anal domination over men and women for many years, but only recently decided to try to cut money on this by coming to a photo shoot with a porn director with her personal slave. Sitting with a subordinate on a chest against a white canvas background, the mistress undresses her and puts her on her knees to first disperse the blood on the buttocks with a spanking, and only then puts her hand in the point almost to the elbow. But this is just the start, because then the mistress pushes the subordinate's ass with a steel expander and only then begins to aggressively hammer her with a strap-on in a doggy style pose
