Let me tell you the story about grumpy boss cat!Jensen and his pining puppy-dog-eyed PA dog!Jared.
Then there is office-sex where Jared bends Jensen over the desk. The End!
Edit: This obviously ends with Dean riding Sam in his fancy office chair. (yes, thank you souslelys for that little tidbit!)
Edit 2: Dean pressed against the full length window, completely naked, while Sam fucks him hard from behind, fully clothed. (WHY THANK YOU saltandburnboys!)
