Tony and Steve's relationship was weird. They both fought a lot and it seemed they couldn't stand to be around each other. (At least, that's what the other Avengers thought. Well, maybe except Natasha...) But, this wasn't the case at all. In fact, if he could, Tony would be around Steve 24/7. That's just how strongly he felt about him. Of course, he would never say this out loud, he's got a reputation to maintain!
But, sometimes Tony just wished he could kiss Steve. Feel the hair at the back of his neck as he held onto him lovingly. He wanted to be able to smile at Steve and say 'I love you" without the fear of being rejected. But, Tony and Steve were just teammates. No more, and no less. That was just their relationship.
Tony sometimes felt embarrassed by the way he felt about Steve, and that was something very rare. Once, when he had been in the kitchen, Natasha had walked in with Clint and the two were having a playful banter. And then Steve walked in. And Tony had froze, and the dropped the glass of coffee he was holding, the glass breaking and the hot liquid splashing on him and Steve. Clint and Natasha had seen it coming somehow, and dodged it quickly. Tony blinked, and then stared up at Steve. Steve stared back down at him in shock, and then asked, "Tony, are... are you alright?"
Tony promptly snapped out of his daze and to his misery, felt his face heat up. He knew Nat and Clint could see it if their raised eyebrows were anything to go by. Tony closed his eyes and bit his lip, nodding. Steve seemed dazed for a moment as he looked down to where Tony had bitten. Tony watched as Steve stared at his lips, and then he cleared his throat, causing Steve to jump and then nervously laugh. Tony rubbed his arm, self consciously. Was his lip bleeding or something?
"Uh, sorry... I'll help you clean this-"
"No, no!" Tony quickly interrupted. He was the one that spilled the coffee so he should clean it! "No, you uh, you don't have to Cap. I was the one that spilled it so..."
Steve smiled fondly at Tony and bent down to start picking up the broken glass. Tony watched him, mesmerized. "It's fine Tony. I've got it."
Tony only nodded, his face even redder, and he glanced at Nat and Clint who were chuckling at his awkwardness. He glared and flipped them the finger. Clint winked at him and he and Natasha left the kitchen, whispering.
Tony sighed and bent down to help Steve clean the coffee. He was such a clumsy idiot around him...
