Great post, I've never been to that specific KTV, but from my experience most local girls are cock teases and they are not down to fuck. Even with PRCs, you need to ask the mamasan who can go out and who can not. Usually, the fee to go out is for one shot and not the whole night. Sigh... it makes the whole experience a lot more expensive.
Have fun at the KTVs. In my experience Club 17 has some of the prettiest girls. It's a great time, but they are more eye candy than anything else and it's on the more expensive end.
