Hmmm...
Well it says on her profile that Kim is a yoga instructor. How about using that as an initial thread to craft a story?
Like suppose she's teaching a class and a new passerby is surprised at the sight of how amazing she can move despite her larger frame?
Maybe she's mentoring similar sized ladies and showing them they can still be great despite their viewed girthiness?
Maybe there is this tough as nails fitness instructor who discovers her and challenges her credentials only to end up outclassed by this supposed 'fat poser'?
I'm sure you'll think if something! Just know that I'm looking forward to seeing it too!

It certainly helps with having someone else's input. As you can tell I'm not the best at the doodles but I'll certainly put something out this week.
