He and Dean ran from place to place, sometimes with others, but always together, chasing the Colt and being chased by Croats.
It was exhilarating, but that might have been the drugs he was becoming so fond of. They removed the edge, at least for a little while.
They had sex for the first time in the woods. It was summer, there were no Croats around, and Cas was as high as, in his own words, 'fuckin' balls, man' and Dean was feeling stressed and neither man was completely there.
Dean cried out God's name, and Cas told him that he and God didn't get along.
Cas pushed Dean away after the former hunter had pulled out and tried to wrap his arms around the human angel.
It felt like one fucked-up holiday, as Cas came down from his high and Dean tersely pretended that that had never happened. It felt good but he knew it signified something terrible.
Cas felt his final shred of innocence flicker and die as they got dressed and went on to find some food.
By the way, these ficlets were inspired by song lyrics. It is Lana Del Rey's song Gods and Monsters and I am absolutely in love with it even though I'm not a huge Lana fan. Honestly, it is absolutely perfect for Future Cas, full of lament and self-destruction and resignation, sex and vices. Definitely worth a listen.
