I'm looking for a cute story that has Dean and Sam investigating a dance club. Because Castiel is with them, Dean tries to teach him to dance for the sake of blending in—but as it turns out, Cas is a quick learner and dances well. :D The story also has a humorous side of Sam/Lucifer. I remember that Sam is horrified that no one notices the devil is either mixing or buying Sam drinks. Can anyone recall this fic?

Found by anon! God is a DJ Thank you!
