The following girls do anal:
Causeway Bay - Michelle (this is the only one on this list worth looking at - but she doesn't do this with new clients)
Wanchai - Sydney
Jordan - Ga Ga and Pui Ling
Mong Kok - magic bed and pussy (don't get me wrong, I'd NEVER do her, just know she does anal)
Tsuen Wan - Ling Ling
I'm sure there are more out there, but most, if not all are more mature and are at or past their
due date. They are more willing to do things younger girls wouldn't do so make sure you stay safe bro ...
Michelle in CWB is also very loud .... and there's a sauna girl in NP that's so loud that it actually gets really annoying !
You're not going find much info on vocal girls.
