“I have the world’s best security system watching this place,” he pointed out.
Natasha flicked the side of his head gently as she got under the covers. “The best security system in the world is a trained pair of eyes,” she asserted.

“Are you going to let us go to sleep?” Natasha asked, amused. Then her smile turned sharp. “Or do I have to tire you out?”
“Please do,” Tony requested.
They didn’t get to sleep for a long time.
