Dean/Castiel - Dean's missed a lot of chances with Cas. This time, he's not going to let it slip by without letting Cas know how he feels. Light slash, light angst

It's Cas's first Christmas as a human... but Dean isn't much for Christmas these days. Perhaps a little nudge from Sam can help Dean and Cas both find the perfect gift. ;) Fluffy holiday schmoop in the bunker with Dean, Cas, and Sam. Mild Destiel slash :)

Nick comes home to an unexpected surprise. But it's not quite the surprise his boyfriend had in mind. (450 words, Nick/Monroe slash) No warnings.

Dean didn't exactly leave his relationship with Crowley in a good place. He didn't realize that was something that bothered him - until now. (Dean/Crowley slash), hurt/comfort, dominant!Dean

When Cas initiates a romantic encounter with Sam Winchester, he clearly expects to be in control. He expects wrong. ;) Sam/Cas slash, mild PWP, mild dom/sub, mild restraint play

Castiel saw the Mark of Cain on Dean's arm - but he's not sure what it means. He has to know how far it's gone, and how much the Mark has left of the man he loves. He may not like the answers he finds. Dub-con, light bondage, mild violence. Dean/Cas.

For the prompt: Sam dies tragically (go as dark as you want!) after Cas tried desperately to save him. He resurrects him, and in doing so, realizes he loves him. Sastiel :)

AU before 9x23, much happier ending. The Mark has taken Dean over completely, and he's a danger to anyone who crosses him - even those who love him. Sam finds a way to get through to Dean before it's too late to save him... to save them all.
