Have a look at Invasian escorts. They have some of the same Thai girls as Asian Options, but a lot (although not all) of the pics are non-studio, seemingly untouched pics.
Patsy, for example, has a dozen or so amateur-style photos taken in her bedroom at her old flat in Paddington. She's also a great fuck, and has always been quite happy to let me try A-levels (in fact, she often is the one to suggest), and has no problem with CIM either (she even swallows). Easily the most PSE of all the Thai ladies I've met in the past 18 months, and the one I've visited the most. She also has a great personality, and is a bit GFE too. Imagine having a sweet, affectionate girlfriend, who is also a completely filthy slut once the clothes start coming off. That's Patsy
My only gripe would be, that she usually only does closed-mouth kissing, although she has been really into DFK with me on occasion. I've absolutely no idea why some days she's into it, and some she's not. I'd just kind of go with the flow.
Gigi is another good one, again, with pics taken in her flat (near Edgware Road) but kind of the opposite of Patsy. Whereas Patsy is PSE with a nice dash of GFE, Gigi is total GFE with a good sprinkle of PSE. Gigi lives in the flat above Patsy's new abode, and they're very good friends; I can highly recommend them as a duo, although, it might be good to at least check one of them out individually beforehand (as I did with Patsy).
Anyway, yeah, those are probably the two Thai girls I can recommend the most, currently. With the exception of Dolly and Anna (the latter sadly long departed back to Pattaya), they're the only ones I've actually felt inclined to return to on a semi-regular basis.
