The little gold link is nearly inconspicuous, at least visually – ever since Bucky had felt it click into place on his hand, his whole being had seemed to relax, a knot that had been pulled so tight as to warp the thread loosening just slightly, to lay comfortably in place.
Adult, first time, hints of D/s. Bucky decides he needs to be married, to belong – to Steve. He just neglects to tell him that. Intense and gorgeous.
