one hour.
I forgot to mention in my review, that she was freshly showered, and smelt great. (I've seen a few other reviews of other girls not being 'fresh')
Further, as by Amber's own admission, she is not very photogenic. her pictures look great, but she is stunning in the flesh, far better looking than her pics (in my opinion, which may not be the same as yours)
oh, and lastly, I actually got there later than originally arranged. Amber was due to finish at 8pm, I got there at 7.15ish. I got the full hour, which I did not expect at all, and would have understood if she cut me short so she could get out at 8pm.
