Yes, this was discussed elsewhere.
She clearly saw what other Polish WGs were doing so put fees from £60/£100 up to £80 half hour and £120 an hour originally so £140ph with anal.
Then went back to £80/£100 and, as you say, now £70/£100, which is about right if she's as good as she is said to be.
Good to see with all these price rises, particularly among Polish escorts, that punters are voting with the feet rather than their cocks, even with popular girls.
Though Carly probably struggled more than most to get the higher rate as her working hours are so limited.
