After the nipples and the cock of the last couple of posts, we get to the balls. In this case a pair of nicely squeezed balls. She certainly seems happy with her handful. Hopefully she has a hairbrush or rod in her other hand that can be judiciously applied.
This is another image I found on the cock torture tumblr site. I’m afraid I don’t have an original attribution.
I always enjoy being taken firmly in hand! 🙂
