Are there K girls out there who do Greek?
Naana and Monica are the only two who come to mind?

. . . .there are also Thai girls at the OC agencies that offer Greek for $$$.  Greek is always YMMV vary depending on your size/girth once the girl has a look at you.  Have had Thai girls refuse me, but K-girl Yoona can handle just about anything.

Just did anal with Yoona about 6 weeks ago. Don't know if you're only interested in Korean girls but there is a girl named Annie that is out in Camirillo who I believe might be Chinese or Japanese but she also offers anal and is a sweetheart as well!

Yoona is back

Nana offers Greek but she might not be magnum approved like Yoona i

Add Yomiko to the list, but she's YMMV
