Thank you!

I'm not sure if this is exactly what you're looking for, but it's one of my favorites, and since it's a J2 version of the movie Dirty Dancing, there's dancing in it, hehe. It's called Be My Baby by titheniel.

Oh and there is freakn_out's "Dance with me ?" too :

And than you for your request because thanks to you, while looking for the link for the story, I discovered that there is a sequel now too called "Graduation" !

Enjoy !

Thank you so much, I'll check that out!

Thank you, I'll definitely read that one!

You're in luck! I only just came across the first story below, and I remembered that you had been asking for dancing recs.

Language of the Body (http://dragojustine.livejournal.com/84967.html) by dragojustine has Jared as a ballet dancer.

There's also The Hidden Language of the Soul (http://jeyhawk-fic.livejournal.com/45760.html) by jeyhawk_fic where Jensen owns a dance school.

Thank you sooo much!
