Just feeling him inside of her (again, her mind whispered greedily) had Natasha shuddering in short order, her fingernails digging into Bucky's shoulders, skin and metal beneath his shirt. He filled her completely, and she wasn't at all surprised to find that they moved together perfectly, a synchrony that could have only been achieved by familiarity, or lots and lots of practice.

Her hips moved sinfully under his guiding hands, rolling to seat him deep each time he rocked upwards into her, and although she wanted nothing more for him to throw her over and take her like the beast she knew lurked beneath that delectable flesh, there was still a slow, erotic thrill to this; coming together with the near-certainty of danger and death looming just beyond. It had her moaning into his mouth, their kisses becoming sloppy with teeth and tongues as they tried to devour each other.

Slim thighs flexing smoothly against Bucky's thrusting hips, Natasha rode him slow and deep, making every stroke last as long as it could before sinking back down on him again. They had twelve or more hours of flight time, after all. And she was so hungry for him.
