This looks like a particularly exciting device for nipple torture. I think it’s called a nipple tree. There’s a name which conjures up a fairly weird mental image. I’ve seen them used before, but this is by far the prettiest, with its chrome and perspex design. I imagine it must ideal for very carefully inflicting just the perfect amount of pain via the clover clamps.
As for the mistress in these shots, I could swear I know who it is, but I just can’t connect the face to a name. It’s driving me slightly nuts, and reverse image searching hasn’t helped. So if you can help me attribute correctly then please leave me a comment with the lady’s name.
Updated: Thanks to a comment by Downlow I’ve finally identified the mistress as the talented Dante Posh. She’s a NYC/NJ based pro-domme, although she also travels extensively. I believe this is from a scene she shot for the English Mansion.

I found these two images on the appropriately named Tortured Nipples Tumblr.
