So... um, I read this fic the other day, just an awesome, shameless, smutty pwp wherein Sam had this smell-kink and just  loved rubbing his face against Dean's clothed crotch and taking in the scent and feel -- I can't for the life of me remember where I found it, and it's driving me crazy.

Any other porny recs along those lines, with scent-kink or facefucking (even vice versa, since I love a bottom!Dean just as much as bottom!Sam) would be welcomed, since that's a huge kink of mine, or anything else you wanna suggest.

...I am so embarrassed to be asking about this, but I want to find it badly enough to ask...... *hides*
