That was the first thought that crossed his mind when Sharon kissed him again. He was in trouble, and he'd walked right into it, and now he was certain that she knew it too.
What made it more complicated (not worse; there was nothing inherently bad about the way the kiss made him feel, aside from his own guilty) was that he didn't even mind. He liked it. He liked her company. He liked knowing there was someone else who understood him, who didn't shy away from what was underneath the mask and behind the shield. He liked talking to her, and listening to her, and making her laugh. He liked that she kept him on his toes and that she kept him in line. She didn't give in, and she held him accountable. And he liked the way his heart skipped a beat when she kissed him back. That didn't feel like a cover.
Steve stared at her, eyes wide, as he tried to process what had just happened and how he felt. "Uh --" Now wasn't the time or place to analyze what had just happened, nor was it the time to ask her why, though he wanted to. He was the one who'd gotten them started, after all. "Y-yeah, okay, S-- Mrs. Washington." He maneuvered their luggage so he could manage all of it on his own and then offered a tense smile. "Lead the way, wife."
