summary: Tony comes back from Titan half dead and bondsick. Steve is the last person he wants to see and the only one who has a chance of repairing it. The Endgame Omega Tony A/B/O break-it you didn’t know you needed.
Tony wonders who will be the first to give up. He wonders if they are the last, if the team is dead somewhere, if they're going to do this forever, just the two of them, until Steve goes insane or Tony withers and dies.
Steve puts his hands everywhere, gentle until he forgets to be gentle. He folds Tony like a pretzel like he does when he's in rut. He hikes Tony's gown up, pulls his ankles apart, dives in like Tony's body still belongs to him.
Tony tries to scent him, more out of muscle memory than need, but Steve's face lights up like he has been living for a breakthrough like this. He traces the line of Steve's collarbone, his strong neck, his chin glistening with Tony's own slick. He presses his face in, and Steve quivers like Tony has single-handedly injected him with enough hope to see him through whatever he sees this as.
Anything? Steve asks, carefully neutral.
When Tony inhales, he smells the desert. He smells the dank of the cave, and the precise reek of the way he puked in his suit when he went through the wormhole and he tastes the dust on Titan when Thanos put Tony's own armor through his body.
