All I Want For Christmas Has Been You for More Than Seventy Years (слэш)

It's Bucky's first Christmas back with Steve in 70 years, just a year since he's come to live with him and the Avengers. Steve's taking him away from the city for the occasion. Bucky assumes it's for his own safety; just in case the hustle and bustle of the New York Christmas Season triggers some of the Winter Soldier tendencies he's been fighting and learning to overcome.
Bucky doesn't mean to take this impromptu trip personally. Doesn't want to be upset. But he's recently recalled and redeveloped his feelings for Steve. Feelings he never shared with him. Feelings he has no idea if Steve shares, so being alone with his super soldier buddy might not be something he's ready for. Only Steve's reasons for taking Bucky away might not be so black and white--or red and green as it may be.
Christmas songs, snowball fights, ugly Christmas sweaters, confessions, and Bucky wrapped up in Christmas lights.
