I've never met either, although I have once bumped in to Katie whilst she was walking a dog a couple of years ago. She's definitely bigger than she makes herself look in the pictures, although that in itself wouldn't put me off - I don't mind a bigger girl. I've seen her on OnlyFans lately as well (treated myself to a free trial of her page). Some of her videos on there show how big she really is too.
I've also discussed her with another SP I see occasionally. She basically confirmed what reviews say, she's a bit miserable and stupidly fake with her moaning etc. Apparently it was so bad the girl I see actually told her to shut up during a duo session!! She did also tell me that if you caught Katie in the right mood, she could be a dirty bitch who's up for anything, but we don't pay to take a risk on a girl's mood.
Both also seem to work with Crystal Dennison a lot. From what I hear, she has the same reputation as Katie. Same waistline too, but (IMO) doesn't wear it as well.
