it involves sam licking a trail of salt up dean's body and taking the lime from dean's mouth all while proclaiming himself a genius for inventing a way to do body shots and something else i can't remember at the same time. i'm pretty sure it also included sam taking a very long drink from the tequila bottle and dean admiring the line of sam's neck from his vantage point on the ground.
any and all help is much appreciated. thank you!
