A demon wants to make a deal with you. You have to have sex with Celestia or he will take your soul. This wouldn't be a huge problem, but you are also extremely attracted to the princess. You have to now make a decision, to either lose your soul or tell Celestia how you feel about her.

And her butt.

This is obviously Twilight's fault.

Contains: Anal, of course.
