Today I'm writing on the theme: "[For soap girls] The flow of mat play plus 6 techniques."
(Quick gloss: mat play is the soapland signature where the girl uses a lubed-up air mat to glide her body over the client. Soapland is Japan's licensed bath-style format.)
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.
After watching this industry for a long time, I've seen the same topic get judged completely differently from "the client's side" versus "the girl's side."
What I can say from firsthand experience
I'll speak from what I've been through myself.
I believe firsthand experience beats theory. In this industry especially, it's "time in the field" that talks, not "knowledge."
Wrap-up and my verdict
The place I end up at most is First Class Ruby. The reason it keeps showing up on this site is simple — it's the shop I actually keep going back to. Take it as a reference.
