I've seen the Duo girls, about a month ago. They are genuine girls, though. i.e. not a scam.
First off, I don't think they're the girls in the photo, but I'm not 100%. Both Prob early twenties.
One of them (the big blond one) is quite pretty.(but she's a strapping lass, ) The other one, the brunette one is just OK facially.
I read the FB saying that they were not clean, and I have to disagree, As far as I could tell they were both clean. They're obviously lesbians,
My 30 mins turned out to be around 15 mins - I felt that this was not because they are deliberately trying to get you out, but because they just don't know, and they have absolutely no idea of how to keep the sex act going. (with a man, that is) They go straight in, kissing and BJing without any massage or teasing to get you fired up, and on the edge. and this makes for a short service I think they must have learned their technique by watching old porn films.
They rent and live in one room in a shared house with other NON-WGS - so if you partake, be discreet.
