This is a sketch by the artist known as Vernice61. He’s featured here in the past, and you can see a whole collection of his drawings over at the Mistress Fantasy blog.
I like his work a lot. The women always looks very calm and in control, and he’s never shy about stuffing all sorts of tortuous ideas into a single drawing. In this case we have inverted suspension bondage, some nipple torture, a hood plus gag and what looks like a large needle about to inserted into the scrotum. However, what really caught my eye about this image was the little hearts emanating from the slaves head. Weird, but kind of cute.
