I read a story where dean is hurt and can't hunt anymore.  He lives with Cas and Ben. I think Cas became human and can't heal Dean.  Lisa might be dead and they found out that Ben was Dean's son.  In this story Cas is in love with Dean but Dean is straight, but because Cas loves him and has sacrificed so much for Dean, Dean decides to try a relationship with Cas.  Dean is uncomfortable with the intimacy at first.

Does anyone know the name if the story I described? Could you recommend story's in which Dean is straight, has never had feelings for men before, but he falls in love with Cas anyways.
