So, your usual Hydra-on-Steve massive gangbang or public-use scenario (chained up or locked into some kind of pillory and left out for anyone to abuse). At first Steve is in overwhelming distress--rage, shame, revulsion, internalized homophobia/masculinity issues, physical and emotional agony. But after a while he just kind of... snaps and hits a zen plateau of No Fucks Given. And that's when the sarcastic running commentary starts. Give me your best unimpressed, disgusted, done-with-this-bullshit Steve Rogers, making snide remarks about his captors' performance, mentally doing up his grocery list, asking himself why all these jerks are so obsessed with rape and whether it has anything to do with Tony and Rhodey's continuing devotion to arguing about Game of Thrones. The more odd mundane details the better--I'm imagining some Hydra office grunt forgetting his keycard and his Starbucks cup after he's done his fly back up, having to come back for them and bitching about how strict the security desk is like he expects Steve to commiserate, and Steve just being like "...seriously?"

Bonus: Aftermath where Steve copes eerily well, downplaying the whole experience and making morbid little jokes about it--until it turns out that, whoops, high-octane emotional numbing is actually pretty terrible, especially for friendships and relationships.
