Extras are at the full discretion of the service provider.
Usually though, you just sit and chat, make out and maybe cuddle for a set period of time. That’s probably true even if you’re Korean, but if you’re not it can be very noticeable.
Unfortunately both of these places seem to be long gone.
There are many more around, and new ones pop up all the time, I just don’t have any exact locations at the moment. Anything more than kissing and touching the girls above the waist seems to get shops in trouble, so it’s usually frowned upon.
The women working here have a little more range in age from what I can see, stretching from 20 to about 30.
Extras are sometimes available, but it depends on the woman you get and your chemistry with her.
