I just discovered this story, and I really like the tone and the pacing so far.
The sheer diversity of the cast is fun, too. (Do you really
travel this much? If so, I'm jealous.

If not, I'm impressed at your research.)
I would love to see a followup story where each route is you meeting up with one of the girls from the first story in their country for a second date where they show you the sights and a good time. I'm not sure how to put this into words, but you make them feel like really different people, even from the short descriptions in the first links, and it kind of makes me want to see what kind of shenanigans they'd each get up to if they had the home court advantage.
