Hi,

I`m looking for this story, definitely Wincest, set during the Benders, where Missy is telling Dean he is really pretty and she might wanna keep him around. And because he angers her, she taunts him about what her brothers might do to him. And Sam who heard this, rushes in horrified, knocks her out and tearfully asks Dean if they hurt him.
I believe it was on LJ, but I`m not sure.

Thanks.
