Today's topic: delivery health, 18-year-olds, Omiya. (To be clear, 18 is the legal floor — every girl here is an adult.)
I'll work through it using my own experience from 20-plus years in fuzoku (Japan's licensed adult-entertainment business), mixed with what I've dug up along the way.
The basics
Let me lay out what you actually need to know going in.
When you've watched this industry as long as I have, you learn that the same topic can read completely differently from the customer's side versus the girl's side.
What experience actually teaches
Let me talk from what I've lived through.
I'll take real experience over theory any day. Especially in this business, it's not what you know — it's how many rounds you've actually been through.
Bottom line, my call
The place I keep 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. Use it as a reference.
