I currently wouldn't pay that for an hour. I have in the past when I had more available cash and it was a porn star who was still filming.
These days that is a ffm with two hot hi girls both of whom are offering anal as well( my next punt)...or 2 hours with one girl I could name one girl who you could see for 2.5 hours for the same money and I think that she is prettier as well.
But each to thier own and if she does it for you and you can afford it then go and enjoy
