[Avengers/Captain America] Teach the Disciple, Win the Master’s Heart (WinterIron)

Why did I keep forgetting to move this story over here? The general plot is that Bucky (an uncle? an older brother?) teaches his friend Howard Stark's little Tony how to flirt and leads him astray. Then Bucky discovers that little Tony is using those tricks on him, but in the end Bucky is still the more skilled one and takes the Tony delivered right to his lips. The age gap between Winter Soldier and Iron Man is about ten years. The pairing is Winter Soldier/Iron Man, with Steve/Peggy mentioned. It's mostly an AU, though it also includes some elements from the original story. The characters will probably be mostly OOC. Why does it feel like I ruined a premise that was clearly adorable... My writing is so bad I can't even look at it. Theme:
