You knew Anne a while back, you used to date. She was this skinny girl who lived in a humble village, she was pretty, but she was weird. She would constantly rave about what it feels like to vore someone, and how she wishes she could. Anytime you kissed her she tried seeing how much of her mouth she could fit on you, but since humans cannot vore, she was never successful. But she sure did try! She'd practice swallowing things larger and larger, only ever being able to swallow a whole orange, which is impressive... but anthro women can swallow a whole person whole. And it made Anne extremely jealous...
Well, eventually you moved to the kingdom of Regium, a human and antrho women paradise! You had to break up with Anne because her mother refused to let her go with you.
It's been 3 years since then, and you're sitting in a bar relaxing after a hard days work, you look over and see... Anne! She looks different though, it's clear she's put on a good bit of weight. You remember her as flat as a board, and now... boom! Curves galore! Even a cute chubby belly!
You drink from your mug, wondering what she's doing here...
