Decoy refused to apologize for selling ponies into slavery under Chrysalis' orders, so Luna threw the book at it, sentencing it to experience 100 years of servitude.

When asked what kind of work it would be willing to do, it signs up for everything, since 'impersonating foalnapped ponies' and 'faking your own death' aren't on the list, and it doesn't have experience with anything else.

What it does have is a ridiculous talent for shapeshifting, and a drive to experiment. With sex.

This story is complete, and I should be posting chapters once a day or so until it's done.
