On their wedding night, Shining Armor is afraid Cadence might be upset, or at least uncomfortable, that he unknowingly had sex with Chrysalis for several weeks. Instead, she wants to hear all about it. She even has a few other ideas, or mares, she'd like him to pursue. Of course her ideas would require tracking down the elusive villain, convincing royal celibates to break their vows, and ignoring a few pesky incest taboos.

Happy-fun-impregnation-time ensues.
