Steve stifles a yawn as he sits himself at his desk. Moving carefully he pulls out the notes from his bag, his everything hurt. Last night, while nothing the Avengers couldn't handle, was rough. He tugs at the cuffs of his long sleeve shirt despite knowing that his bruises were covered. The Wrecking Crew packs a punch, thought thankfully due to his enhanced healing all evidence should be cleared up by the end of the day or easily excusable by a small fall down some stairs.

He reaches over for his coffee mug and takes a long sip. He looks down at the mug with a smile. He had got Tony and himself matching mugs a little over a two years ago as an anniversary gift. He picked out a wonderfully bright hot-rod red for Tony who seemed quite drawn to the color and a deep blue for himself.

Tony was late again today. He knew he would be when he received the text saying he would be working late on his projects and that he would be unreachable. He didn't mind, he loved his partner and how passionate he was in his field. And he loved how happy it made Tony when he brought him in a coffee.

Actually, it was actually fairly convenient. As the Avengers had been called out to face the Wrecking Crew there would've been no way for Steve to answer any messages or calls Tony could have sent his way. It saved him from having to potentially find some sort of explanation as to why he dropped off the face of the earth for a few hours… and all the trouble that could lead to.

He hates having to hide such a secret from Tony. But how exactly do you brake it to your long-time boyfriend that you're 'Captain America'? And believably at that? One day he will tell him, he has to. And before horrible something forces his hands. He wouldn't want Tony to find him out by getting a call saying he is in hospital and in bad condition.

Steve sighs and tries to focuses on his notes in front of him. But he can't. He can't get the image of Tony at his bedside in hospital, looking down at him with such fear and hurt. He can't put Tony through that.

He hears the door to his office open an looks up to see Tony standing in the doorway with the coffee he got for him this morning. He smiles up at his partner, putting down his notes, "Hey, you" he greets him, "Long night?"

"Like you wouldn't believe." Tony gives him short but sweet kiss on the cheek before continuing, taking seat across from him. "I think it would be slightly more beneficial in the long run if I diverted my efforts to developing an alarm clock that would actually wake me in the mornings rather than my current projects… but only slightly."

Tony leans back in his chair and groans. Steve winces at the sound.

"Hey, no. I'm fine, just too long spend bent over a desk working…" Tony tries to assure him "I'd have much rather been bent over the desk by you"

But it doesn't work. Tony looks tired, he always looks tired after a long night of working on his projects. Some nights more than others. Last night seems to have been one of those hard nights.

He gets up from his desk and gets behind Tony. He runs his hands all over the man's back, massaging all the sore muscles. He is careful not to use all the strength he could on Tony's back, not wanting to hurt him. Tony groans in pleasure and he smiles proudly at being able to draw such sound from Tony both in and out of the bedroom.

A loud knocking at the door draws their attention away from one another. Prof Becker is watching them from the doorway, grinning at them. "The meetings in five," she says before he leaves them, presumably to head over to the meeting.

"I guess we better get going" he says sadly, he would rather be running his hands over Tony's back then sit a midterm review meeting. He removes his hands from Tony's back. His partner sighs in disappointment. He gives Tony's shoulder a quick squeeze. "Maybe we could get dinner after work?" he asks, hopefully. They had both been so busy lately, it would be nice to spend some time together. He wouldn't complain there was some sex down the line later.

"Sounds great" Tony says as gets up out his chair. Steve follows him out of his office, mind wondering off to tonight.

The End

Notes:For the prompt: "Everything is better with identity porn - especially tropey tropefic. Pick a well-loved fandom trope or cliche and add identity porn! Sex pollen? Fake dating or marriage? Genderswap? Some good-old-fashioned hurt/comfort? Identity porn ALL the things!"

Identity porn + University/Teachers AU + Hurt/Comfort. I don't know if an AU counts as a trope so I added in some angst and hurt/comfort.
