Pairing: Gabriel/Sam
Prompt: Dean finds out that Sam and Gabe are shagging
After Gabriel's freak out session when he found about him and Castiel, Dean had thought they were over and done with.
And then, he wakes up early one day, and walks into the kitchen and finds his little Sammy and the archangel having a little…hanky panky involving pancake syrup.
Dean will forever deny that he shrieks like a girl and almost chokes on his own spit, but, unfortunately for him, Gabriel had taken video.
