I've read a few really excellent fics, J2 and Wincest both, involving shotgunning, and I know there have to be more out there. Rec me whatever you've got!

-doesn't necessarily have to include shotgunning per se; can just be about smoking up/getting horny
-other people can be involved, but please, either Jared/Jensen or Sam/Dean should be centrally included.

Thanks! :D
