Closest station, Stepney Green, district line. 5mins walk, into an open estate which is discreet and clean from what I saw but I went 11ish so didn't really pay that much attention. Shes located in a small residential flat, there is another girl working with her in another room, while I was there another punt arrived which was a bit funny but as I was in my room, didnt actually see them or it would have been awkward.
Regarding anal, didn't even attempt as stated above but she did pretty much everything else I asked. For a bill its worth it as you can bust as nut as many times as you want.
Regards
