Author's Note: I signed up for this prompt over at sevenfists Evil!Sam Fic-A-Thon: Sam's always had evil impulses, but until Stanford he couldn't indulge. Then he meets Jess, who is seriously turned on by his badass, evil self and they have evil, sexy fun together. And maybe when Dean comes to get Sam in the pilot, they decide to have evil, sexy fun with him, too.

Then my fic!wife monotonygirl said she had some ideas to help me on my way. They turned into an Evil!Sam verse of its own, inspiring her to write the fic that this is now a companion to. So, this is my follow up to her meltingly wonderful She Knows The Rules. (Go, check it out, I mean it! )

Disclaimer: Lawsuits make me cry. I don't own anyone.
Summary: Sam’s possessive of Jess when it comes to other guys, but when Dean shows up, Sam wants to remember what it’s like to share something with his brother.
