Harry Potter: Mind Control

Octavius Black, a wizard born into the prestigious pure-blood family: The Blacks. Son of the Black couple: Druella Black and Cygnus Black III, and brother to three beautiful women: Bellatrix, Andromeda, and Narcissa. His training nights with his sisters were always exhausting, and he wouldn't allow them to marry into any other noble house; no one would have control over their bodies except him. Malfoy? A weak and dull wizard who follows another weak guy; Edward? A Muggle-born who doesn't deserve his sister's hand; Voldemort? Too weak to be a Dark Lord, so he would assume the position masterfully.
