She used to work from the same house as Chelsea Hart and Zoe in Mansfield. Chelsea used to work every day but Zoe was only in a couple of days a week. So Karen started working out of Zoe's room when it wasn't in use. I saw her once, a long time ago and just remember thinking.... shit..... Chelsea is in the room next door - I should have booked her.
I only saw Karen once. She was slim with natural boobs and a thing for 1950's lingerie. Karen got a reputation for being a diva. Bloody hard to book and happy to mess punters about. I remember Chelsea having to stop during our booking once as some guy was pounding on the front door. He'd made a booking to see Karen and although he'd arrived, she hadn't. I also seem to remember Karen had trouble fitting my cock in and we ended up finishing with oral.
I think there was a lot of friction between Chelsea, Zoe and Karen and Karen ended up either leaving or being asked to leave. Since then, she pops up from time to time. The profile name changes and a few different photos get added. The price always seems to go up too. I certainly wouldn't say she's worth £150 an hour. Put Karen and Chelsea side by side and you'd pick Chelsea every time. She's got a better likes list, she's a lot better looking and she's also a bloody sight cheaper.
I'd avoid Karen. I have no idea about any 'nasal' issues, but for the hassle you get, there are better and cheaper girls about.
