//"Mortal": After Clark has the fight with Lex and goes off to sleep with Lana, Lex watches (via the many hidden cameras he obviously has hidden in Lana's apartmemt). Later he shows Clark how much better he is at it than Lana. Edited to add : Did someone already write something like this? Thinking about it, I have this vague sense I've read something like this, and wouldn't want to steal someone's story idea. //

I agree with you, there *is* (are?) fic(s) with that description, now if my eyes would not drop any minute, I would love to look them up for you, I hope I can do that tomorrow :)
