Princess Celestia invites Dragon Lord Ember and Changeling King Thorax to join her in Canterlot in the name of furthering diplomacy between their species.

What she meant by that was... not exactly what they had in mind. Luckily, there won't be anything in there anyway once she's done with them.

Contains kidnapping, bondage, femdom, mind-melting, dragon tits, and not a lot of consent. You've been warned.
