A friend of mine has made a Bondage Pack. This friend is the owner of Kaede, an OC that appeared in the comic I still post in here. This pack contains the Equestria Girls versions of your favorite ponies. In bondage of course. I've been watching the process of how these pictures have been made, I liked the result a lot.
You can take a look of how it looks here:
Here is a promo of it:
You can find the download links for the pack in the description of both pictures.
