Summary
“Now, the way I see it, you’ve got two choices.” Lex's voice dips into something smoother, more intimate. “You can deny this, pretend none of it happened, and slink back to your Fortress to ride this out alone. Hope no other Alpha catches the scent and decides to stake a claim. And if they do? Well…” He lets the implication hang.
“Or,” he says, stepping back into Superman’s line of sight, “you can stay here with me.”
Lex smiles, satisfied and sharp.
“No strings. No questions. No one ever has to know. And trust me, I don’t want anyone else finding out about this any more than you do. A secret like this?” He leans in slightly, whispering conspiratorially. “It’s far too valuable to share.”
Lex develops a compound that triggers Superman’s heat, but the side effects don’t end there. As Clark spirals, Lex begins to change too, in ways he never planned for. What started as control begins to shift… and neither of them is ready for what comes next.
