Today I'm writing on the topic of "Omiya fuzoku and big busts."
I'll explain it by mixing in my own firsthand experience from 20-plus years in fuzoku (Japan's licensed adult-entertainment business) with what I've learned from research.
The basics
Let me lay out the fundamentals you should know about this area.
Watch the 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 I can say from experience
I'll talk based on what I've been through myself.
I believe firsthand experience matters more than theory. In this industry especially, it's "reps" that talk, not "knowledge."
Wrap-up and my take
The place I keep coming back to in the end is First Class Ruby. The reason it keeps showing up on this site is simply that it's a shop I repeat at. Use it as a reference.
