Untrue

Bucky kisses him again, soft and sweet, and Tony lets himself melt into it, relaxing under Bucky’s touch. “I’ve got you,” he murmurs and Tony smiles. He shouldn’t, not really, because failed marriage or not this is a really shitty thing to do to Steve. Wouldn’t be as bad if it wasn’t Bucky specifically but it is and when this all comes crashing down, and it will, it’s not going to be pretty. But Tony’s has always been selfish so for now he chooses to ignore that in favor of enjoying the feeling of whatever this is. Tony wraps his arms around Bucky’s neck and presses him further back into the chair he’s in. “Yeah, I know,” he says, nipping at his lip before he kisses him again.

I have a weird thing for infidelity fics, no idea why. Anyway, to be clear everyone in this fic is a little bit of an asshole minus Peter and Sam mostly. In Steve in Tony's case they're both kind of major assholes, if (at least to me) sympathetically.In case it wasn't super clear in the tags, there is infidelity in this. Like a lot of it, everyone fucks someone over with cheating. Now, for Steve it never gets physical but that's mostly because I don't think it'd be in character for him to act on the eyeballs deep emotional affair he's in with Sam (which, for reference, becomes a thing later in this- SamSteve- but I didn't tag it because it vexes me when I look up SamSteve to find a lot of things that are not primarily them. Anyway). Now Tony, he doesn't fuck anything up small so he goes full tilt here. And James doesn't much care for most people so he doesn't care for people's feelings either. Minus his own, and Tony's but only because he decided to care about Tony. Also, Peter is still spidey and aunt May comes into this later so she's still around!So I THINK that's everything, but mostly I want people to be forewarned that cheating. Happens a lot in this. Also, we do get Steve's PoV semi-frequently even though we start with Tony so I think I give them equal time to display that their marriage sucks and give them time to be sympathetic asshats.
