Twilight has been pent-up for years, never able to find a pony she liked, that could keep up with her intellectually and really get her, but now, after finding a spell that can rapidly copy memories, she's found a solution with the mirror pool. After some test runs, it's time to show Rarity this method of risqué relaxation.

Inspired of course by Castle Clean Up, and written for the Incest is Wincest Self-cest September contest.
