Still a dearth of this kind of prossie it seems, however there is a glimmer of hope for those that want to take this path. Recently took the plunge and joined seeking arrangements for a trip abroad. As I had it for a month I also looked in London and there are loads of very hot black & mixed race girls on there. Seen two (one of whom I fucked - sadly her account is no longer active), and have plans to see two more. The girl I saw was an abdolute babe and up for anything.
A lot of the girls on there want stupid amounts but a fair chunk of the black/mixed girls are happy with 150 for a few hours of fun. You also need to get a hotel but you can get one for around 60 notes, so 210 in total. Expensive but you do get a lot of time in my (admittedly limited) experience.
Its also a lot more hassle than AW as you’ll get more misses than hits but if you want a month of hot girls then its 60 notes for the SA subscription. Should probably note that there seem to be a lot of scams on there and questionable ethics from SA themselves. I personally am happy with my membership but I would say if you do join its defo worth contacting (our) admin to get access to the SA thread. Lot of good info on there (thanks guys).
