Op adding- double trashy bonus: Steve asks why he never tried to stop the others/him from being punished and Bucky looks at him and is just all like - 'You are all grown adults. And I know for a fact you took cock like a champ before the serum. A bit of punishment wouldn't break you.' Or something like that.

Like Bucky really thought they all just, knew the consequences and did things anyways, like Steve starting fights pre-serum. Hell with Steve maybe he hoped it might curb his behavior a little.
