I'd say not. She was ok at £120 but I probably won't be returning at £140. I am more of a gfe kinda guy and I can get that for £100 from a polish girl.
Lizzy is a different experience though -more filthy, and when I think that the extra £40 gets me cim, facials and anal it doesn't seem so bad. I really really enjoyed fucking her ass last time out, but it could have been better. I liked it when I asked her where my cock was - more filthy talk like that would have been amazing. Sadly not to be.
Lizzy should be my all time best ever punt - but she isn't and I'm not sure why. Maybe she's too passive? Dunno.
At the moment I'm enjoying my gfe with Roxy way more even though it's much more limited services.
Everyone's different though.
