I'm having one of those moments where I'm really struggling to come up with the words for how much I loved this! This is the perfect reunion-sex story, and just the way I imagine they would be together - desperate and needy, but able to comfort each other and bring some relief. I loved this:

"I called out for you when I was on the island, when I was half out of my mind," Lex says softly. "I wanted you to save me."

Clark presses a trembling kiss to the scar. "I’m sorry I wasn’t there for you," he whispers.

"Hey." Lex cups his chin, makes him look at him. "You were. Or I wouldn’t be here."

*sniff* Just beautiful! And for me, the ending allows for some hope - Clark will find a way to make it last. :o)
