The problem with duos from the agencies is the expense of it and the dubious quality. As has already been described on another thread here about Asian/Thai girls the quality of service has declined. As I've said, make the effort on AW and eventually you'll be surprised. I can't say more than that because I'd be giving away a confidence but it can be done. In fact, Suzi Li does duo doesn't she with her friend who is in her gallery, I think so anyway. Also, I've many times walked into a Thai or Chinese parlour/flat and been offered a 3 some with the girl and another working there or I've suggested it and if the maid looks good, as they do sometimes, there's always that possibility, even if it's a 'come back later' thing. Be creative and imaginative, that's all I'm saying.
