Two and a half centuries ago Sixt had been a young witch with little control. In a fit of jealousy, she'd cursed the demon with an addiction spell. She thought better of it shortly thereafter, but couldn't findhim to take it back. She did something unforgivable, but she wantsforgiveness anyway.
Deliverance had been a slave to sex for so long he could barelyremember life before. When he learned the compulsion that was a neverending itch was an addiction hex, he was elated because hexes can bewithdrawn by the witch who casts them. But the euphoria was short livedwhen he learned the price he'd have to pay to have the curse reversed.
