Summary
Sam and Dean are on a case, but decide to have sex (in an alley) before doing their usual interviews.
SMUT, obviously.
No redeeming value, just another stop on the Wincestuous tour of America.
Originally, this was part of a case fic, but I never actually got around to writing the case, so instead of leaving this shelved on my desktop, I decided to go ahead and post it. So here, you go: some random Wincest smut for you. Enjoy!
