In the Arms of the Uhh

"Dude, you've got wings." Dean just woke up in an abandoned warehouse with no idea how he got there. His brother finds him, and Sam has . . . wings? Wings that only Dean can see. With no memory of what happened past walking out of the motel room, what's Dean going to do? Well, he's going to . . . try not to touch the pretty feathers and hope Sam doesn't notice. Wing!fic. No Slash.
