All Rogue would have to do was ask, and Steve would gladly give her a massage. He wouldn't let his hands wander, or try to turn it into something else, either. He understood sore and aching muscles, even if he wasn't really susceptible to them anymore. He might even suggest it, if she was still moving stiffly when he returned. He didn't want to push at the moment, as it didn't seem to concern her. He'd leave her be, see if she was able to deal with it on her own - and if not, he'd suggest trying to help.

Steve would never be able to resist that smile. He placed a gentle hand at the small of her back, and leaned forward to kiss her lips this time. "I promise."

Going to his bedroom, Steve quickly changed into a t-shirt and running shorts, before grabbing his phone and turning it on. He'd already stuck it in his pocket and was exiting the bedroom when it started to buzz with a message. Pulling it out, he frowned in puzzlement at the text Natasha had sent him, earlier that morning, it looked like.

Enjoy the fireworks last night? Stark is totally jealous. ;)

Steve stood, in the middle of the living area, tapping out his reply with his thumbs, still frowning slightly at the screen.

Didn't get a chance to see any actually. Why is he jealous

He couldn't find the question mark button, so he just hit send, before putting the phone back in his pocket.
