If she's not trans then she's drawn the genetic short straw with that lack of arse, lack of hips, boxy torso and incredibly lean (and vascular) limbs.
She's obviously had LOADS of work done, which of course isn't always a sign of being trans. In some of her photos there's something weird going on with her jawline, maybe stubble? Look at the very last couple of pages of her gallery to see what I mean.
The fact she's a barebacker and seems genuinely nuts seals the deal either way.
