Let it go mate.your talking so much your not even reading. Everyone has a bad punt now and then. As its your first time to N5M.this place and 42G and Ginza are very well known for having new to industry girls with zero experience. They explicitly say on their profile asking you to lead the way and teach them.
So don't expect a 25 year hard core prostitute super skill set that will suck you dry.
The selling point for these NTI is just their youth , innocence and girl next door vibe. Now that you seen these, you might realise these are not your type and best to avoid them.i saw her and didn't have great expectations like you. But she did everything without complainant and I thought it was great. Why don't you try some of the more seasoned pro in this shop, they will give you a good time and probably be more to your service level expectations and afterwards report back. All girls are human too, not all will be having perfect days having to serve some ugly punters day in day out.
