Came up with an idea that I got from a fanfic: Jareth was making Sarah an offer that day in the Labyrinth but she was too young to understand it. Now that she's older, he's returned to make it again. Will Sarah be willing to live the darkly sensual lifestyle he leads? Can they overcome their past to find a future together Basically this will be where he goes after her after she turns 18 and moves out. She's still virgin and he wants to make her his and show her the joys of carnal pleasure.
This will involve elements of BDSM. The line I am referring to is when he says, "Fear me, love me, do as I say and I'll be your slave!" To me that was saying, "Fear me, love me, obey me and I will give you the world at your feet and give you all my love and undeniable pleasures."
