she seems to be an independent and not agency. She identifies as Asian, not Korean or Japanese (or any specific nationality/ethnicity).
The typical K-girl session I am familiar with would be
welcome kiss and hug and perhaps some light touching
be lead to the room.
some additional kissing and groping then disrobing - often getting some assistance and her folding the clothes or hanging them
to the shower for the mouthwash (the blue toast you hear about)
in the shower to get cleaned for the action. Generally part of the shower will be both some sensual rubbing and a preview BJ.
Out of the shower the girl will dry you first though sometimes they will remain in the show a short period after you get out to freshen themselves more.
Back to the bed one of the standard scripts is you lie down and get the sensual massages (light touch and generally lots of breast and nipples rubbing you and cat bath (kisses and tongue). You're lying face down generally and if rimming is offered (and wanted) that would follow.
flip on to your back for more of the tease which leads to another BJ
Here you might get your first shot off or you might hold it and move to the cover and then start of intercourse
Generally that will start in CG and move to ACG and often will go to RCG/RACG
They will then switch to bottom and you'll be in some form of missionary based position and from there you can move to other positions that you like.
Depending on time and ability you might take a short break and then start on round two.
If there is not second shot you will generally get offered a massage or they will curl up with you for some pillow talk.
Then the shower again, probably get some more kissing and light play.
She will almost always stay in the shower after washing you and address her own hygiene needs. If you are still drying off very likely she will help further then dry herself.
Back in the room she will assist you with dressing (generally)
She may dress for business again or just toss on a robe and walk you to the door.
More often than not they will have some candy or mint to offer, almost always a small bottle of water for you -- though that is often offered earlier so you don't need to take it with you.
Kiss goodbye at the door -- and depending on how well thing went between the two of you that might be more passionate or just a nice kiss of goodbye peck your GF might give you before leaving for work or something like that.
There can be variations in the script but the general flow and creating the sense you are being sexually pampered is what I would say is the K-girl trademark session.
That said, COVID has impacted the willingness of some in terms of kissing but not many that I've noticed. Also I'm talking about the DMV market and it might not be quite the same as where you are.
But, as you see I'm not sure you got a good K-girl session and the Yuna doesn't seem to claim to be Korean. Oh, the pricing is not really Agency pricing and even a bit high for what most of the indie Korean providers in this area which follow the same script as the agency girls and deliver just as well (so I consider them K-girl even if some purist think K-girl must work at a K-agency) .
