Kurt let himself in to Blaine's house and tossed his keys and his bag onto the couch. "Blaine?" he called out. There was no response, but there was some sort of noise coming from the basement. Kurt crept down the stairs, following the noise. He rounded the corner and saw Blaine, in basketball shorts and a tank top, hitting a punching bag. Kurt watched in pure astonishment for a few minutes.
The song on the radio changed to one that Blaine didn't like, and he turned to change the station, which is when he spotted Kurt. "Not expecting this, are you?" Blaine asked.
Kurt looked at him. He couldn't tell of Blaine was angry or just surprised. "Um, not really," Kurt said.
Blaine plopped down on an old couch and took a sip from a water bottle. "Sit, Kurt. I'm not mad you walked in on me. This is just, something I don't like people to know."
"Why not?" Kurt asked.
"Because I took up boxing when I was being bullied at my old high school," he admitted.
"That's nothing to be ashamed of," Kurt said. "So you know how to defend yourself. That's useful. And really sexy."
Blaine smiled. "You want me to show you some moves?" he asked Kurt. He was suddenly really excited.
"Yeah!" Kurt said.
Blaine pulled him to his feet and Kurt rolled up his sleeves and walked towards the punching bag. "Woah, there, what do you think you're doing?" Blaine asked.
"Um, getting ready to box?" Kurt said.
Blaine guided him by the shoulders to the other side of the room. "You have to work up to the punching bag. I'll start you out with some simple punches. Blaine taught Kurt a few punches, which was only the beginning of a fun afternoon of lots of laughs.
