Interesting. I saw Tiana a couple years ago. I did not repeat because she was bigger boned than I like, with a round face (and round belly). But she was really sweet and service was moderately good. I am now relieved that I haven't repeated recently.
Some of the girls, as they get older, make a huge effort to stay in shape, and if you are ok with a slightly MILF-y experience, they often are toned and with amazing service (Happi, Min, Blue, Yomiko, ...) Sounds like Tiana does NOT fall into this category
