Met a girl from this stable before, twice, both times for a FFM threesome. Used to be managed/maid/pimped by a TS, I’m guessing this is the guy you spoke to. The girl seen was in no way seemed coerced and we (me and missus) had a great time with her, hence the second visit.
It didn’t seem dodgy at all, however I did receive random texts telling me about new girls in the area for a couple of years, which wasn’t very discreet.
On the subject of pricing, all the girls have that strange individual pricing structure, all I did was call up and say what I wanted and then was quoted a price, I can’t remember now what the price was, but it certainly wasn’t what was written on the profile, with individual prices for fingering, oral etc
