Despite his own rather ignoble actions the previous evening, hearing that other men had approached Peggy with the intent to get her into bed... that immediately raised Steve's hackles, filling him with a burning desire to go find said individuals and teach them a lesson about respecting a lady. Did that, then, make him a raging hypocrite, considering he'd been no better last night? There was the matter of the drugs, of course, and his being in an altered state, but that still felt like an excuse somehow, like he was trying to duck out on behaviors that, by all rights, he still shouldered responsibility for.
Regardless, hearing Peggy's admission made him want to punch those unknown someones. Badly.
At the very least, it sounded like Peggy had taken care of that herself when the need had arisen, and in spite of his low mood, Steve felt a smile begin to pull at his mouth. This was Peggy as he liked her best: fearless and in control and never a person to be trifled with.
"Good," Steve offered quietly. "Anyone who treats you like that deserves nothing less." He was including himself in that assessment, too, though the fact that she said she'd been conflicted... as if perhaps she'd even considered saying yes.... Sweat prickled at Steve's temples and the back of his neck at the thought, heat flooding his body. Because even if that wasn't what either of them wanted, precisely - a night of passion where one of them was horribly compromised - that didn't mean it wouldn't have been enjoyable. Steve had never in his entire life craved another person's touch as much as he had last night, and if Peggy had actually gone with it, followed him to the shower, or to his bed...
Steve swallowed quickly and shoved those thoughts away. The fact that he was actually able to redirect his attention to Peggy (and the fact that those thoughts had only managed to get him a little hot under the collar, without any other physical effects) did, at least, seem to indicate that last night's drug was thoroughly out of his system.
Hearing Peggy admit that she wanted him in return normally wouldn't have calmed Steve down any, but there was something about the way she said it, the flush on her cheeks and the way she lowered her eyes, sweet and decorous, that mostly just made him want to apologize all over again for how inappropriate he'd been the night before. He couldn't believe that she was forgiving him so easily, let alone inviting him over for a hug, and though he hesitated for a long moment, in the end he couldn't possibly say no to that.
He crossed the room slowly, giving her time to change her mind, but her arms stayed open, and after a final moment's resistance, Steve allowed himself to step into her embrace, his arms wrapping around her shoulders rather than her waist, which felt safer, somehow.
"I'm sorry, Peggy," he murmured as he curled into her, so that his mouth was near enough to her ear. "I really am."
