Fics like Crystallised Starlight

Stripped of his supposed Alpha identity in prison, Lex Luthor is rescued by the very alien that put him there - Superman. Now, with nowhere to go, Lex is taken to the Fortress of Solitude where his true nature slowly begins to reveal itself in a way that might destroy them both... Or: Lex is an Omega hiding from his true biology and Clark slowly shows him that it's okay.
