Hard to Swallow

Castiel knows all about the campus bad boy, Dean Winchester. The man’s reputation is spoken of enough that even Castiel has heard the stories. He doesn’t usually put much stock rumors, but he can’t seem to stop the loathing he feels toward Dean for his actions.
With the mistakes of his past looming right behind him, the last thing he needs is another pretty boy playing with his emotions. It’s clear that Dean will be able to get under his skin easily, so he usually does his best to avoid him.
That is until Dean makes him an offer he can’t seem to refuse.
It’s a very simple bet. If Dean loses, he has to give up the indiscriminate sex he’s rumored to favor, for an entire month. If Castiel loses, he must live in Dean’s home for the same amount of time. Either way, the bet would change both of their lives forever.
