Bruce stood nervously at the front of the church beside a fidgeting Steve, looking around at the others standing in the pews. The rest of the Avengers sat smiling and joking with each other, Pepper and Coulson chatting happily about something or other. Nick Fury and Maria Hill looking slightly less serious that usual, maybe the hint of a smile gracing their faces. Other SHIELD agents the team had grown close to over the years they'd worked together. Bruce found it slightly against character that Tony Stark would be ok with such an intimate ceremony, but he'd do anything to please Steve, and Bruce got the impression he was almost relieved they kept it to close friends – family - only. Inside he was a hopeless romantic. Especially when Captain America was involved.
Steve looked the most nervous Bruce had ever seen him, it was almost adorable. He was standing straight in his 1940s dress uniform which really did things for his figure. Bruce couldn't wait to see Tony's reaction. Steve turned to him.
"This is really... scary," he said, his breath a little fast.
Bruce smiled and adjusted Steve's collar, "Love is." He smoothed down Steve's lapels. "But if it helps, Tony is probably just as scared as you are."
Steve smiled and patted Bruce on the shoulder, looking him in the eye with gratitude before turning back towards the door of the church.

On cue, the guests all rose and waited for the doors to open. They almost jumped as the music blared out of the speakers. The riff for Back in Black came out strong and hard as the doors opened to reveal Tony in a beautifully tailored black Tuxedo. The smile that broke on Steve's face could have out shone the sun.
Tony walked down the aisle with more sass and personality than most people could ever hope to muster in their entire lives, obviously adoring the attention. Bruce smiled wide as he heard Steve let out a chuckle. Many of the guests were moving with the beat, Tony's abundance of life was infectious. It was difficult to believe this was also the vulnerable and broken man they all knew existed.
The music faded as he reached level with Steve, whom he turned to face. He took in a deep breath, running his eyes up and down his lover's body.
"God Steve, that uniform needs to come out more often," he murmured under his breath, causing Steve to go a delightful shade of scarlet.
The guests seated themselves as the minister began to speak, Steve and Tony intertwining their fingers and smiling at each other. Bruce could feel the love radiating from every person in the room, and was proud that Captain America had chosen him for his Best Man. This family was all he could ever had wished for and more.
