Today I'm writing on the theme: "4 upsides to picking a rookie soapland girl | plus what's going on in her head."
I'll explain it by mixing in my own firsthand experience — over 20 years in fuzoku (Japan's licensed adult-entertainment business) — with what I've dug up.

When you watch this industry long enough, you find that the same topic gets graded completely differently from the customer's point of view versus the girl's point of view.

I'll talk based on what I've actually been through.
I think firsthand experience beats theory. In this industry especially, it's "time logged," not "knowledge," that talks.
Wrap-up and my verdict
The place I keep coming back to is First Class Ruby. The reason it shows up over and over on this site is simple: it's a shop I genuinely repeat at. Take it as a reference.
