Sunset Shimmer just can't get enough of Twilight Sparkle. Not only is she dating the young lady that just came from Crystal Prep, but she's cheating on her with the Twilight from Equestria! It must be because Princess Twilight knows a spell that gives her a big advantage in the area of lovemaking, an advantage that tends to grow straight from her lap.

But what happens when Sunset's worlds collide, and she's caught in between two Twilights? Can she possibly handle that much bookworm passion?
