It'd be fun to see a pokemon au (with lighter worldbuilding than tma canon) where jon/martin/tim/sasha are close friends with benefits (and/or dating each other) who sometimes offer each other sexual favours as the prize for pokemon battles. Either they hold matches whenever any 2 of them feel like it, or hold tournaments as a group? With enough communication that nobody's going to be pushed into anything they've vetoed, but while they're competing they get a kick out of leaning into 'the winner gets to do whatever they like with the loser' banter. Either Jon's some shade of sex-favourable or -neutral ace, or he only asks & gets asked for nonsexual kink if he's sex-repulsed.

Bonuses:
- flirting during the pokemon matches, before the smut begins.
- optional inclusion of extra characters in the close fwb group/polypile (if they're also human & not evil here): Gerry, Melanie, Georgie, Basira, Daisy, Michael Shelley, Annabelle, Oliver...
- Martin trains a Joltik :3

(- veeery optionally, if you headcanon some pokemon as people of various species, not animals, and they're able to communicate effectively with their human partners, e.g. through telepathy or writing, and it's an au where pokeballs aren't a thing, they just live together and enjoy sports matches as social equals with the humans, then feel free to include pokephilia with those ones. In which case, some of the characters named above could be pokemon.)

Dnws: scat, noncon (but cnc is fine), underage.
