So at some point, HYDRA recaptures Bucky. They punish him by implanting a device that makes him come whenever they press a button. Every day, they set up another humiliating scene and take pictures/videos as he helplessly comes from extra degrading trash treatment.
(Of course they rape him, but the focus is on making him come in the most degrading situations, like when they make him kiss their dicks afterwards, or piss on him, or let their dogs have a go, ... I fully trust the imagination of this dumpster.)
+ all the shame + they film in a way that doesn't reveal the device, it looks like Bucky orgasms all on his own + the orgasms are so intense he moans + they do it in part so Bucky won't run again, because where would he go when everyone has seen those videos (or so they tell him) + they start each session by watching last night's footage together with Bucky
