It happens almost too quickly, but once the moment passes Natasha is suddenly very aware of how out of breath she is, despite the fact that the physical exertion she put out isn't anything that should effect her let alone wind her. She doesn't move, instead leaning into his cool skin and resting a warm cheek against the side of his head, reveling in how glorious it is to have an ice-pack-boyfriend ready to go before she loses it forever. His comment gets a breathy but amused laugh out of her, and Natasha's grip loosens on his shoulder so she can instead drape both arms around him and let them hang freely as she rests the full weight of her body against him.

"Maybe she didn't want to ruin the surprise," she manages after a few moments, and after a thoughtful silence she pulls back just enough to catch his eye with a playful glint shining in her own. "Or maybe she thought you'd get scared and back out if she told you. And you know what?" Natasha leans in until her lips brush against his ear, and her whisper is almost sing-song with tease, "I bet she didn't even leave the house." A grin slips into her words, "she knows where the fun is really at."

It takes a few minutes before Natasha can drag herself off of him, and once she does she half-lies, half-collapses into the bed with a content hum and no effort to cover herself. "Don't look smug." She's not even looking at his face, her eyes closed. "Appreciate it while you still can, soon you're not going to be able to wear me out."
