Cotton Candy: The trickster with an oral fixation (смешанная)

Basically set in season 5 episode 8: changing channels. Kind of need to have watched it or read about it to get the gist of the first part. Or you can skip to the sexy Gabriel smut. I have intentions of making each chapter based on a certain sexual act, or kink, or a mix between a few. Eventually there will probably be a little of everything for everyone :D.
Gabriel, under the guise of the Trickster is drawing up fun for the winchesters, another hunter, Astrid North is the one who initially found the case and tags along. Only to get warped into a porno with sasha grey! When she finally 'gets away' and runs into Loki, he offers her a remedy for her 'issues' and even his own personal touch. The offer is one she just can't resist.
