California Shallows by
toxica_fic is the story I've been reading the last few days whenever I needed a break from studying.
It's RPS, AU, rated NC-17, and long.
Summary: "Jared and his friends are spending their last summer together before college on the beach in an out of the way town in sounthern California. Enter messed up Jensen with an odd fixation with the ocean. Jared's summer blow out just got more interesting."
I loved it.
