Russian Mistress Kristin has done terrible things to guys. She loves to lock them in tight bondage and chastity! But now it is time to test Mistress Kristin! She thought this would be easy, but we locked her in full chastity and chained her collar to the wall. She was then elbow and wrist cuffed, behind her back. And Mistress Kristin isn’t super flexible. So that was hard! She suffers beautifully for us, as she tries to deal with the uncomfortable position until we decide to unlock her. But since she is a Mistress, we leave her in bondage just a bit longer than most girls! That should teach her!
