Something I thought of, bizzarely, in the shower and then whipped up in literally five minutes. Please let me know what you think.
Kurt returned home the next day still in the same clothes he had left in, still wearing the same dumb smile he had had on his face since it had happened, still feeling electric all over. He walked in to the hall and hung up his jacket, calling out a hello as he wandered further in to the house.
"In the kitchen, buddy!" he heard his father's voice shout.
Kurt went in to the kitchen to find his father stood on the far side of the room, facing the window and tinkering with what looked like a jewelry box. "I'm just trying to fix this for Carol," Burt explained. "Damn thing keeps getting trapped shut."
"I slept with Blaine." Kurt wasn't quite sure why he admitted the fact so bluntly, and to his father, whom Kurt was pretty sure didn't want to hear all about his sons exploits with his boyfriend. Nervously, Kurt awaited Burt's reaction.
"Oh," Burt said blankly, his shoulders sagging as he dropped his screw driver.
They were both silent for a while. Kurt looked down at the floor, wrapping his arms around himself.
"I just thought you should know," he explained quietly. "I'll spare you the gory details, you probably aren't interested. And if this was a girl we were talking about then you'd probably be clapping me on the back right now or-"
"No," Burt interrupted softly.
Kurt looked up, surveying his father with a questioning gaze.
Burt turned around to face his son and shake his head. A small smile was playing on his lips. "No, Kurt. I'm not going to clap you on the back. I'm going to shake you by the hand, because you're a man and that's what men do."
Kurt felt the tears descend like a film over his eyes. He ran at his father, almost knocking him to the floor as he wrapped him tightly in a hug. Burt clutched his son just as firmly back. "Thanks dad," Kurt croaked.
They pulled away. Burt was still smiling. He offered out his hand and Kurt obligingly took it. They shook.
"I'm proud of you, son," Burt declared. "You waited for the right person and the right moment - and I don't care if that person is a boy or a girl or a damn unicorn, because I love you, and I always will, no matter who you decide to love. You got that?"
"Yeah dad." Kurt nodded. "I won't forget it," he said.
Burt patted his shoulder and Kurt took his cue to leave. As he reached the door, Burt called him back. "Kurt, you did use protection, right?" he asked.
Kurt felt his cheeks grow slightly flushed. "Of course," he replied, without turning around.
"Good," Burt said, and Kurt could hear the tight discomfort in his voice. "Because I know neither of you can get pregnant or anything, but there are tonnes of things going around out there and… I'm not say you or Blaine are diseased, or anything, no, I'm just saying…"
"Dad," Kurt groaned.
"Wait, wait! One more thing," Burt said.
"Yes?" Kurt sighed in exasperation.
"He didn't- didn't force you or anything, did he?" Burt questioned. "I know that he wouldn't, but-"
"No, dad," Kurt said. "I wanted him just as much as he wanted me." He could have kicked himself after for saying that. Now things were definitely awkward.
"All right," Burt said finally. "I guess you can go."
Kurt shook his head. "Love you, dad!" he called behind him as he walked away.
