Fics like Close Your Eyes

There are some relationships so taboo they’re irresistible... After John and Mary break up when Sam is 11, Sam moves away with Mary and his new step-father while Dean stays in Kansas with John. Fast-forward 12 years and John is dead, Sam’s just returned from Europe, and Dean’s gone and married a billionaire and become a male model. As the boys reconnect, Sam becomes increasingly fascinated by this successful, happily-married version of the big brother he barely knows, a fascination that soon turns into an overwhelming mutual obsession. Warnings: non-hunting AU, infidelity, promiscuity, angst, recreational drug use. The Dean/OMC part is quite prevalent in this story, also the OMC in question is basically Alan Rickman ;-)
