Set in sixth year. Harry finds the Half-Blood Prince's recipe for a powerful love potion. He resolves to do the noble thing: seduce every girl in the school. Lemons. Harem. Harry/Multi.

With the resources of the magical world, it's foolish to think two students couldn't spend a night together if they wanted. Unless they forget they're in a school of other horny teenagers. Then things can get messy - in more ways than one. No slash, but lots of pairings.
