Today I'm writing on the topic of "Warabi soap, on-site childcare."
I'll mix in my own firsthand experience from more than 20 years in fuzoku (Japan's licensed adult-entertainment business) with what I've dug up in my own research.
The basics
Let me lay out the fundamentals you should know about this subject.
When you've watched this business as long as I have, you learn that the same subject can get graded completely differently depending on whether you're looking at it from the customer's side or the girl's side.
What I can tell you from experience
I'll talk from what I've actually been through.
I believe firsthand experience beats theory. Especially in this business, it's a world where "time on the floor" matters more than "knowledge."
My bottom line
The place I end up going back to is First Class Ruby. The reason it keeps showing up on this site is simple — it's the shop I actually repeat at. Take it as a reference.
