I've got another suggestion from why-choose: winpala. We all know that Dean Winchester has a... special relationship with his baby. And Sam isn't exactly unfamiliar with her, either—he's literally been her. So, this week, it's carfucker's week. Whether it's Deanpala, Sampala, or both of them double-teaming their baby, give me all your thoughts about our favorite third Winchester (sorry, not sorry, John, Adam, and Mary)
it's canon to me that Dean has a Pavlovian response to the creak of leather seats and heavy breathing. he could hear it in passing on tv and chub up
less grounded in canon, but I love the idea that Sam gets intense emotional flashbacks connected to the car. any time his sweaty skin sticks to the seat he's young wonder summer lust and gangly fifteen. when Dean's arm goes around him so to look back and reverse Sam's under big brother's arm protected home
also... I have written them as the world's most dangerous threesome...
