It's not too specific, but you get a decent-sized collection of tranny material here.
Tranny Porn Pass is a bit generic in a lot of ways. The content is mostly non-exclusive, and all of the options are pretty middle of the road. A lot of the quality is a bit below par as well. However, they have some big numbers here, and the tranny niche helps them stand out a bit, so it's not all bad news. Plus, the HD videos look decent. All in all, it's not over the top awesome in many ways, but it could be a solid join if you're not too picky, especially for the price.
