Check the previews out - we show our weekly previews on the site and we update with at least 6 unique sets per week before bonuses (nice bonus set this week see the Freebies section).
We do show Brazilians but they are not our main focus which is N.American tgirls. Out of the 24 or so models we show a month, maybe 4-6 at most would be Brazilian.
There are NO other sites showing this amount of models or updates specializing just in black transgenders. If you are only interested in hardcore take a look at
