She is fat.
She's not 'slim' but I wouldn't describe her as 'fat', or as a BBW. She is cute, friendly and responsive, at least in my experience - although I am pretty 'vanilla'.
ETA - what I can't dispute is that she is not 'as advertised'. I got quite a shock the first time I saw her, when she opened the door. I was still naive enough to think the photos would be accurate.
She is however the only local WG I have been back to see, primarily because she is a good enough actress to convince me, in the moment, that she is enjoying things. She is the only WG I have seen that can do that.
