What if Malfoy had a hot sister? Harry's 4th year at Hogwarts & the Triwizard Tournament looks a lot different with Draco Malfoy's sister constantly tormenting him and his friends. And what happens when a certain quarter-veela enters the picture? Harry/Fleur/OC.
What if Harry had a twin sister, someone who grew up with him as they ventured through life together, instead of him facing the world by himself. And Malfoy has a sister as well, which makes life even more chaotic. Sequel to Battle of Wills, with AU elements. Story begins with Harry's 4th year. Harry/OC/OC/Fleur. Warning: wincest, BDSM, harem.
Harmless fun for the family.
