Tony starts calling Steve "boss," and Steve has all sorts of feelings about it. It ends up coming up in bed. The results open up some new areas in their sexual relationship, and maybe reveal a few things about Tony, and how he feels about Steve.
All Tony wanted at this party on Xandar was to troll people who didn't recognize him, and fluster Steve in front of the Nova Corps by wearing a t-shirt with his shield on it.
Unfortunately, Tony gets more than he bargained for when his merch shirt for Avengers power couple Captain America and the Winter Soldier gives people the wrong idea about their relationship.
When Tony comes back from a very bad D/s date, in pain and abandoned by his dom, Steve offers to help Tony out and give him all the aftercare he so desperately needs.
Steve is moving into Tony's penthouse and insists they go through old boxes of Tony's things to find out what should stay and what should go to make room for Steve's things. But the boxes contain more than just old clothes and Christmas decorations, and it leads to a shocking discovery for Steve.
He let his hands rest, warmly, on Steve’s shoulders, against his neck. “I just want you to fuck me, soldier,” he managed to get out, breathy. “I want you to fuck me, yes, in my ass, and not stop. Again and again, until it’s out of your system.”
Steve and Tony and a marathon sex encounter. That's it, that's the fic.
Steve wakes up to the fact that no one ever compliments or even says thank you to Tony, and that he has fallen into the same trap of painting Tony with a specific paintbrush.
This is how he showers a very confused Tony with praise to make up for it.
He startled at the sound of Steve’s voice, nearly dropping his tablet. Tony looked around and bit back a curse. He hadn’t been paying attention to where he was walking and had wandered into a part of the Wakandan palace he really didn’t want to be in. He quickly looked back over his shoulder. There was Steve with Barnes and Sam right behind him. Steve took a step forward. Tony did the only sensible thing he could think of at the moment. He ran.
Tony's a brat. It's just the truth. There's always that voice in his head that tells him to push, refuse, disobey. And that means no dom has the time or patience or skill to take him down into the subspace he craves.
