"Crucio." Rita said silkily, the spell delivered at a fraction of its true potential. Like Harry said, you have to truly mean for it to hurt. I gaped as I saw my wife shudder in pleasure at the pain, moaning softly as the curse ended and Rita's mouth was buried in Narcissa Black's quim. I could smell how wet she was as her breathing sped up and Rita put a finger inside her with deliberate slowness. My wife whimpered out of frustration as Rita refused to work her up any faster. I was disturbed at how they were using the curse, but also intrigued and a bit jealous to hear those sounds come from Narcissa.
