I'm looking for a specific story of Dean/Sam that focuses on Dean talking dirty to Sam and using feminine language. Details below

The piece opens with Dean and Sam eating in a diner. Dean is flirting with a cheerleader/waitress and Sam is jealous and drinking a milkshake. They go home and Sam is angsty until Dean wins him back using a long shirt and pretending it's a dress/skirt. They both get off on the feminizing talk.


Thank you for your help!
