533 was my go to for Anal as most of the milfs did it and charged no extra. I have described this place before as a literal 'cum bucket' before, and I stand by it. That is what it is. It isn't a GFE, or about a fantasy. Its a jizz factory.
As others have said, there is no place in Sydney like it, if you turn up and all the rooms are full they will just take you in to the breakroom and have you fuck there like it is business as usual for everyone else.

These days I prefer big tit ML milfs at massage joints. But if you are punting regularly in Sydney you should go once and consider it an initiation lol.
