Twilight Sparkle wakes up to an unexpected thought, and now she just wants it to go away. The idea is embarrassing enough: an erotic liaison between herself and Princess Luna. But Twilights problem runs deeper. She cant ignore this idea, however much she tries. She decides to write it out as a story, to clear the thing from her mind.
Now she needs to finish her story quickly â€“ because if she falls asleep before its done, the Princess of Dreams will get to see that idea for herself.
