This is a beautiful set of two(!) images.
Kama is naked, except for black rubber stocking, high platform heels and a black hood. Her arms are tied by her side and a very, very, heavy-rubber collared is slapped around her neck.
After she is put on the one bar prison, a hard metal dildo in her vjj, she can virtually not move anymore. She can't move without the hard metal hurting her, she can't step off the OBP (it's not called a "prison" for nothing :)) and her neck is tightly collared.
In the last shot of the clip you can see the struggle of endurance in her watering eyes...
I love her for it, and so should you!
note: the images you are getting are uncensored.
