Dipper looked at the dark outline of Bill suspiciously. "What kind of deal do you have in mind? he asked.
"Oh, just a... personal favor," Bill said, wringing his hands, embarrassed and excited. "You see, it gets pretty lonely being an all powerful four-dimensional being and I was hoping that"
"You want to fuck me, don't you, Bill?" Dipper interrupted.
"Well, yes, as a matter of fact. You'll get something too, of course. I've seen what you want, and I think I can provide the love of your sister. And in return, I get to try the human reproductive process" Bill said, outlining the deal. "Whaddya say," he said, sticking out a hand engulfed in blue flame. Dipper thought about it. He wanted Mabel so bad. No, needed her. His life wouldn't be complete without her being his, and only his.
"It's a deal, Bill!" Dipper said, grabbing Bill's outstretched hand and giving it a quick shake. The flames spread from Cipher's hand to Dipper's, sealing the deal.
"I'll be back to collect my end of the bargain tomorrow night!" Bill laughed as he faded away. The room faded to white as Dipper woke up with a gasp. He checked the time; it was now about seven in the morning. Dipper smiled to himself, thinking about his plans of what to do with Mabel when she would finally be his.
