Aha! I thought I recognised Britney, and her room! I have had the pleasure of visiting her several times, so I guess I have the honour of being the first to report...
Yes, she works in the Amsterdam red light district, the given address (Stoofsteeg 7 (middle)) is correct. I assume she still works the night shift, which starts about 20:00.
Britney is a very friendly and welcoming girl, and gives very good service. (And value for money - unlike many girls there you can get different positions without rushing for 50 EUR.) She consistently gets good reviews, so you can consider this an unreserved recommendation!
When you look at her pictures bear in mind that she is a very petite girl... I would hazard a guess at somthing like 30D/E.
No, this is definitely not her first boob job! The last time I saw her (last year) I think must have been two boobjobs ago... Then, they were actually bigger! This was why at first I didn't recognise the pics - her boobs looked smaller than I remembered. It was reported on the ignatzmice.com board that sometime around March this year she had another upgrade done (in Thailand). There were amazing reports of her chest now being twice the size of her waist! Since then she has obviously undergone a downgrade, as reported in the Dutch excerpt posted earlier, taken from hookers.nl. This report is consistent with the size in the pictures in the first post.
She is definitely a fan of big boobs and wants to go as big as feasible, so I am guessing the latest downgrade must have been due to some health reasons, or problems with her latest set of implants, rather than being a choice to go smaller. A shame, but of course health must come first. To be honest, I had thought her second-biggest size (when I visited her) was pretty much the maximum practically possible, given her tiny frame! Thus this does not surprise me greatly.
In any case, she still has a more than respectable set and is well worth visiting! I hope it will be possible for her to go bigger again in the future. Please treat her well!!!
