Harry Potter had discovered the book of his dreams, the Spellbook of Desires, which was chalk full of spells and potions all aimed at satisfying the user’s needs. In the case of Harry and his best friend Ron Weasley; Hermione and any other girl that twinges their fancy were now fair game. Harry knew that his fourth year at Hogwarts would be his most interesting year by far. Presently, Harry, Hermione and almost all of the Weasleys were situated at a large campground in anticipation of the Quidditch match of the century. Harry and Hermione had been invited along with the Weasley family to watch the finals of the Quidditch World Cup in the top box of the brand new Championship Quidditch stadium. The best part of the event so far however, was the purchase and subsequent use of a rather peculiar spellbook; a book which satisfied the reader’s every sexual desire. In the case of both Harry and Ron, that definitely would mean Hermione, but by happenstance, Harry had used a potion on Ron’s younger and very attractive sister, who was currently sleeping off the sexual exploits Harry and her had taken part in.
