Twilight accidentally comes upon "Young Colts, Tight Bondage", the literary sensation despised by critics and adored by teenage mares all across Equestria. She feels herself drawn into the series and spending a lot of her alone time with the books. She finds out that the author, an obscure Ms. E. I. Xirt, will be visiting Ponyville soon. Twilight tracks down her idol, but she's in for a weird surprise.

This is rated teen, but it's on the heavy side as you'd expect. Nothing too explicit.
