On a trip to Baltimare, Twilight and friends discovered a small metal orb that was beeping. Unable to identify it, Twilight takes it back with her to the castle and studies it. On the third day, however, the orb makes its purpose known.

Thankfully for her, it doesn't do so to her directly.

Unthankfully for Chris, it does.

Added the Sex tag because of Chapter 5 and the problems that arise due to what happens in that chapter. Don't worry, there's nobody doin' the snoo-snoo.
