Story: Twilight and Rarity's Magic Book

[Shipping] I have so many kissing Twilight/Rarity pictures that could be used for this, but I'll spare your virgin eyes anti-shipping people!

Warning: It does come very close to being a Fap Clop Fic 

Description: When Rarity returns some books she borrowed from the library, Twilight Sparkle discovers a book she's never seen before among them called Reform School Fillies - a book with incredible magic powers.
