Pure Pain (смешанная)

Tumblr prompt: okay so the last fic [Pure Lust] you wrote was so good and filthy like, yes go off. but i was wondering, could we have something with nat and sam? i’ve always liked them together and i love sam calling her mama, now that you’ve put it in my mind ;) maybe sammy is being a bit of a brat and nat has to put him back in his place in front of everyone?
Or, where Sam pays for the bratty attitude he had during the Avengers' last orgy and Natasha makes sure everyone sees it.
