Yeah, that's about the prompt... Anything with Bucky on a leash getting yanked around, basically. More specifically, I have this image of Bucky getting conditioned to obey before they attach the metal arm. They put him in a choke collar and have his remaining hand chained down to his side. His balance is all thrown off because he's still not used to the lack of an arm, so whenever the leash gets yanked he can't help but fall over. Maybe they tie the leash down below his feet, so he's forced to bend over, and then they take turns fucking him like that. But that's just what I'm imagining! Any leash porn would be wonderful, really.
