A/N: Just a brief idea in drabble-ish form, I don't know of anything will come out of this. I write when the muse strikes, or when I'm inspired by a review or a random thought. This was somewhat random, somewhat Tumblr sparked, but who knows what may come. If you like it, let me know, I might add, but I just felt like getting this one out. Sorry it's short, I'm not really skilled at writing over 500 words at a time :P

Disarmament

They kind of have this routine.

He greets, she smirks. He talks, she flirts. He blushes, she smiles.

And then he walks away.

He visits her in the gym, he trains a little bit with her. He focuses on maintaining a level heart rate while he dodges her fists. She stops by the lab on occasion, stays a while to be assassin-made-lab-assistant.

But when she has him pinned on the ground, her torso against his, each feeling the other breathe heavily and the heavy thudding of hearts, or when he reaches behind her in the lab to grab something and has his forearm brushing against her waist - he panics.

Doctor Bruce Banner has devised countless methods for remaining calm in stressful situations.

And Agent Natasha Romanoff disarms each and every one of them.

Yoga, martial arts, meditation, opera, breathing exercises, everything, everything goes out the window when Natasha enters the room.

Which is partially why he does it.

He's a scientist, it's in his nature to experiment, to test boundaries, to change variables and see what might happen.

So he purposefully will put himself in these situations where he finds it difficult to stay calm.

But he never in a million years imagined that she would feel the same way.
