As she walked by the dumpster, a smell hit her. That smell. She was well acquainted with it. She'd know it anywhere!
The urges hit her again like a dump truck, and she cupped her blobby belly with a hand. Come on, just a few bites. It's so wrong all that food is being wasted, isn't it? When it could just as easily be in your fat willing gut?, the voice chimed.
She inhaled heavily for a few moments, fighting it, but it was in vain; she soon bobbled up, swung the dumpster open, and grabbed a half-eaten slab of ribs. She tore into it like she hadn't eaten in days, slurping up what little sauce didn't end up on her face or on her bulging belly.
"Haah... hhah... Aaaah~" she breathed, like an addict who just got her fix. She groaned, going back into the dumpster and devouring a handful of hot wings, a fourth of a beef sandwich, a half-drunken soda cup, and other assorted meats. She climbed out, covered in sauce, and squeezed her now-pot belly, letting loose the biggest blast of gas yet. Bbbbbrrrraaaaaaaaaaaaaaaaaaaaaaaapp!
She smiled, dazed, and sat her softening rear down. She had a feeling this was the skinniest, and the least gassy, she'd be for a long time.
"Holy crap!" an ecstatic voice called from the alleyway entrance. Most of Karen's euphoria diminished.
"Holy crap!" Lily repeated, looking similar to a stuffed sausage in her own dress. "You've become such a slob! In just a week, you're dumpster-diving for meat that's making your belly do backflips! Uggh," Lily cringed, smelling Karen's gas, "and you've gotten so gassy!"
Karen could only sit like a kid with her hand caught in the cookie jar. "Wh-What are you going to do?"
