It's a shame that some guys have this mentality. Yes, you "bought" this girl for an hour but that doesn't entitle you to treat her disrespectfully. Anyway, I find that treating a WL well have provided very positive outcomes in a session, especially from those at Ginza. They're all girls willing to please, and treating them well just makes the experience all the more genuine.
Good review by the way. I've had a chance to meet Momo but not have a session with her and she's just absolutely gorgeous.
