That has the potential for some wonderfully filthy fantasy sex. Like Castiel’s thigh keeps pressing Dean’s (or Sam’s) in the theater and they keep thinking about how he looks and what the sex would be like.
…Sam would tell him he didn’t need to volunteer for the virgin sacrifice. Cas would be understandably alarmed until he realized it was symbolic. And then he’d do it. Because he wanted to participate. And the boys would have to watch him suck the cream out of a twinkie held at the crotch of a really cute girl.
I’ll just be over here.
… Do I need to go write this now? A little wincest + castiel?
