Steve walked into the avenger's tower main room. When he couldn't find anyone, he tried the roof, where Natasha and Clint frequently practiced their Mixed Martial Arts on dummy.
When he walked up, the air was cool and pleasant. He spotted a partially sweaty Natasha beating up a dummy that looked as if it had been run over by a car, smashed by the Hulk, and then left in a gutter to decay until further notice.
Her fist met the dummy's face and broke his foam nose off.
"Whoops," Natasha said, still thinking she was alone.
"That poor dummy," Steve stated, revealing himself as Natasha failed to reattach the dummy's nose.
She barely flinched, "Hi Steve," she said, turning to face him.
"Hi yourself," he began, "Dummy." Steve said, waving to the mangled mess of a practice dummy.
"Spot me?" Natasha asked, lifting her leg to kick the dummy in the side, but failing to meet it's head like she wanted.
"Sure, just try not to aim for my head," Steve said, coming up beside her and putting his hands on her waist.
Natasha immediately thought to herself, he's gonna try to kiss me, isn't he?
But he didn't. And he continued spotting her until she seemed to have mastered the difficult skill.
As she lowered her arms to his hands, she decided to give him a push in the right direction, "How about we get something to eat?"
"Sure, I think Tony's heating up some pizza and hot dogs in the microwave," Steve said, heading toward the door.
"Steve!" Natasha huffed out a breath in the cool air and demanded to recognized.
"What?!" Steve said, taken aback.
"Do you want to kiss me or not?!" she said angrily.
Steve stopped and turned back to her, "Maybe…" he admitted.
"Then do it!" Natasha demanded in her military-like way.
"Fine! I will!" Steve said, equally demanding.
He leaned in and they kissed until a crashing noise came from the kitchen.
"Tony." They said at the same time, making a B-line for the roof access door.
