Being a mean bugger, I aim to pay £120 ph, but have paid more on occasion. No. Dear does not necessarily mean better.
Had a really memorable first meeting today with a girl who ticked every possible box, except the big boobs one, and at £120 was value.
By contrast, I paid £150 to a Perth escort, to find OWO, DFK and fingering were off the menu. Not good, despite the girl's attractive looks.
