Lady Anja needed to control this guy and she did so using her ass worship fetish. She had to make sure that things worked out the way she wanted them to and that is exactly what happened. The poor guy had to endure the pain and humiliation of being an ass slave and being forced to do some crazy and humiliating things that the mistress chose for him to endure.
Mistress Lindsey wanted this guy to be turned on and that is exactly what she did to him. The mistress made sure that the guy checked out her ass and that he worshipped it the way she wanted. The guy was super turned on but she did not do anything with him. Instead, she left him high and dry as he begged her to do some nasty and naughty things with him.
