Oh, this is horribly compelling. Imagine them taking it even further and completing fucking up Bucky's entire system for understanding and expressing emotions and sensations. Like, they've removed the metal arm for repairs and are tinkering around with the raw bone stump on the end of his left shoulder:
"How does that feel, Soldier?"
"good, sir"
"Surely you can elaborate."
"It feels fantastic, sir! Please keep doing it!" while he's jerking around in the restraints from agony, tears streaming down his face.
Later, with Steve, he's not even really able to tell what feels good or not. Is that sweater soft or itchy? Does he like spicy food or is it hurting his mouth? Who knows - certainly not the Soldier! (Or, just, not to deviate too much from your wonderful prompt, Bucky just smiling continously and inappropriately through all kinds of debriefings, medical procedures, etc and Steve is simultaneously devastated and creeped out).
