When Twilight becomes determined to unravel the mystery of how poison joke does what it does, Fluttershy agrees to help since her reaction to the flower is the least debilitating among all their friends. Things don't go as planned, of course, and the experience changes Fluttershy and Twilight's lives in ways neither of them could ever have imagined.

This story is quite tame as far as the "Sex" and "Fetish" things go, but I figured I'd better rate it "Teen" and put the tags on just to be safe. Oh, and the cover image comes from Asssha on DeviantArt.

This story is a sequel to Breaking Out to Avoid Being Broken In

Chrysalis has had better days. In fact, she once had it all. A loyal horde, her enemies cocooned as sources of food for her hive, a home not cluttered with useless items like banners, doors, and toilets. Times have changed for the former Queen and she’s going to have to figure out how to adapt to her new life. Or, you know… do something sensible like try to get her old one back.
