Today I'm writing on the topic of "delivery health, beautiful skin, Saitama."
I'll lay it out using my own firsthand experience — over 20 years in fuzoku (Japan's licensed adult-entertainment business) — mixed with what I've turned up through research.
The basics
Let me organize what you need to know going in.
Watch this industry long enough and you'll see that the same topic gets graded completely differently depending on whether you're looking at it from the customer's side or the girl's side.
What I can say from experience
I'll talk from what I've actually been through.
I believe experience beats theory. Especially in this business, it's a world where reps matter more than book knowledge.
My bottom line
The place I keep coming back to is First Class Ruby. The reason it keeps showing up on this site is simple: it's a shop I actually repeat. Take it as a reference.
