So, it's common knowledge that CW Bucky got a lil chubby. What if things go a bit differently, Bucky comes back home with Steve, and finally he can eat what he wants and doesn't have to stress about being in peak physical condition. Like he doesn't full on let himself go and go all overweight or obese, he just has a bit of a tum instead of washboard abs and a rounder face and he likes it that way. Steve likes this Bucky too, with his dad bod and long hair and beard and a newfound love for flannel.

It all goes to shit when Bucky's old friends (HYDRA ofc) show up when Steve's not home and aim for a good ol' trash party, just to find out that Bucko looks a lot different now.

Cue humiliation, fat shaming, HYDRA goons faking disgust/being genuinely disgusted yet still fucking Bucky, degration, shame shame shame etc etc.

+++ HYDRA friends tryin to get to Bucky by suggesting that Steve must be grossed out by him too / 'wondering' why Steve still puts up with Bucky
