A well-written 'fuck or die' fanfic. Sixteen year old Sam is infected by a giant slug creature and will die unless he can fuck someone asap and Dean cannot just leave his brother to die, can he? The angst that follows is classic Winchester.
"I'm sorry," Dean croaks. He drops his face into his hands before Sam can see it crumble. He inhales raggedly, anger churning hot inside him, spilling through his limbs. He digs his fingernails into his hairline; he wants to tear himself apart. Wants to get his knife and stab, stab, stab.
