Gotta admit, thigh-high leather boots are a step up from leg pouches in kinkiness.
I really like this pairing, it has such a "prank gone sexual" vibe to it.
It's pokémon, so it's probably Shuckle* juice or something.
*Which has never been outright confirmed to be alcoholic, kid friendly franchise and all, but it's heavily implied since it's the fermentation pokémon.
I really like the detail that Marcille is the one backing away in panic. Falin isn't grossed out, just surprised (because she can never figure out people are in love with her, this has been established).
