Inspired by the Yelena chapter of the "Bucky thinks rape is love" fic

A female Hydra or Red Room agent decides to appoint herself Winter Soldier's "girlfriend". Is it just to be cruel? Is it an assignment from the higher ups to keep him manageable? Anyway, he'd do anything for his girl, from sexual things he doesn't like or understand, to murdering for her.

Bonus would be him struggling with a post ws consensual and healthy relationship
