Not at all the way she wanted to hear that, either. Peggy's expression didn't crumble or quail, but something inside jolted sharply, swooping up and then tumbling down with enough speed to make her feel fleetingly nauseated. Swallowing her heart. That's what it was. A hand reaching inside to pluck at things that didn't need to be stirred right now, and damn those baby blues anyway.
"You don't want me like this," she insisted, hand sliding up, pressing against his brow and then into fair hair, gentle. Always gentle, even when crushing desire. "When you're not in control." When there was no guarantee he'd remember any of this tomorrow, and if he did, it would be tainted with regret. Maybe with self-loathing. He might even blame her for taking advantage, and Peggy might be complicit in a lot of things she wasn't proud of, but nothing would make her go along with something that would ruin everything.
Everything they hadn't been yet, but could be if they were careful. Peggy was good at careful, at least most of the time. With Steve, the lines could get blurry.
Fingers carding through his hair, she smiled wistfully. "Go shower, all right? Cool off, clear your head. I'll wait." Whether or not that was wise, she didn't know. Peggy wanted to leave this room as much as she wanted to stay to make sure Steve could get some rest and shake off this, whatever it was.
