Sam Winchester's thoughts on Dean and Castiel, relationship wise. !DESTIEL!

What happened in the pit that Sam should never know about? This is a Samifer Fanfiction. May contain violence, smut, and possible fluff.

This was supposed to be a Samifer one-shot but since the word count is 6,000+, it won't let me put it all in one chapter thing XD but I hope you enjoy and yeah. I'm mostly posting this because my dearest friend was like "You've got to post dat!~" So yeah. Just tell me what you think about the story in the comments and I think I'm gonna start taking fan fiction requests if you guys want me to write you somethin'. Ok I need to get this story going! :D
