As far as I know, Nikki, Roberta has never done porn. She definitely escorts, however. Why don't you book a trip to Brazil and pay to have her all to yourself?
In the meantime, enjoy this vid of the first runner-up, Shantell D' Marco. My suggestion to you, you godless tranny slut, is to download this vid in HD, imbibe whatever intoxicant's that you prefer, and then watch this on the biggest screen you can and wonder at the most awesome un-pumped and gym-toned ass in all of Tranny-dom. Fucking amazing.
