That was a good 'oh'. Steve liked that he could still surprise him a little, hopefully even when he couldn't Tony would still like it. Maybe for some familiarity bred contempt but Steve who'd never got anything familiar absolutely thrived on it.
He mouthed at Tony's hairline, where the skin tasted a little salty and couldn't help but wonder if he'd got worked up kissing Bucky, if he'd felt that flash of heat. But actually it was better not to think about that and he guided him through the lounge and toward their room. Their young people were still out but Steve still kicked their door closed behind them, glad to be home. "Lucky me," Steve said against his skin.
Steve wasn't rough but he was firm, man handling Tony through the bathroom door as he pulled his lover's shirt over his head.
