There is a lot of airbrushing going on but that doesnt hide that these girls are still beautiful in person. There is a video of a tgirl on there and she's fucking nice, so I wouldn't be too worried.
I hear this happens a lot on escort sites though, the lady might be the same one from the pictures, but they edited out all stretch marks/pimples/freckles/blemishes etc. so when you meet her she doesn't look as nice..
EDIT: heres a link to the videos, I think they change it periodically, before there was only 2 but there's 4 here and they're different. don't know yet if any of these vids feature tgirls, so i'll watch them now :
