Work Text:
Dean had thought maybe the farmer's market Sam dragged him too wasn't so bad after all. Sam was happy and absorbed in this own... thing, leaving Dean be. Dean had found the food trucks and was facing the fattest, tastiest looking burrito he'd ever seen in his life. They even put bacon in it.
It tasted pretty good too until Dean felt a sharp pain and the familiar taste of blood in his mouth. At first, he'd assumed he'd bitten down on something hard that really shouldn't have been in his burrito. Closer inspection showed there were teeth in his burrito, which was disturbing enough. It snapped at his finger when he tried to dig one out.
His burrito had a mouth.
He was bitten by a burrito.
Could he just have a normal lunch?
