Twilight Sparkle may be the princess of Friendship, but at heart she is a scholar first and foremost. Once presented with an opportunity she'll stop at nothing to gain more knowledge of the world. So what if she has a family reunion scheduled for tomorrow? A few hours in a lab won't hurt anypony!

However, her last experiment is going to have consequences she couldn't possibly imagine. Sometimes there is just no way to be prepared for what you might find out...

This story was originaly intended for the Accidental August contest.

Warning: contains incest, dubious consent, transformation and general sillyness.

First story in English I ever published. I will be happy to recieve any advice or feedback.
