This story is a sequel to Party Animals
Before Rainbow Blitz was a fat party animal, he was a fit, healthy athlete. Before that, however, he was a very heavy teenager, as was his close friend Butterscotch. Life at school wasn't exactly easy for them, as we'll see here...
Contains: fat/obese ponies, anthro ponies and high school shenanigans. Rated Teen for fetish stuff.
Looks like Word might have put in a few extra spaces in places. I'll blame Dumb Belle, though.
