Today I'm writing on the theme of "Nishikawaguchi soaplands, petite girls."
I'll mix in my own firsthand experience from 20-plus years in the game with what I've dug up through research. (Fuzoku is Japan's licensed adult-entertainment business; a soapland is the bath-and-service format.)

Watch this industry long enough and you'll see the same topic get judged completely differently from the customer's side versus the girl's side.
What experience tells me

I believe firsthand experience beats theory. In this industry especially, reps matter more than knowledge.
Wrap-up and my verdict
The place I keep going back to is First Class Ruby. The reason it keeps showing up on this site is simply that it's a shop I repeat at. Take it as a reference.
