A/N: Got a prompt from blue4summer on tumblr that I thought would be fun to fill. Hope you like it!

Prompt: "What if it turned out that Kurt was really good at it! And that Sebastian really likes it and sees that Kurt is more than a fashion diva and stuff! And kinda falls in love with Kurt."
Rating: PG
Ship: Kurtbastian, Klaine (mentioned)
Notes: Nothing really to comment on, just something I wrote in one sitting. Un-beta'ed, so beware!

Sebastian walked casually into the gym, winking at the receptionist and earning a wink back. He grabbed a towel and tossed his gym bag into a locker. He might as well start with stretching; he wasn't really feeling up to a challenge this morning. He threw the towel over his shoulder and strut out of the locker room.

Sebastian heard the dull thump of shin on punching bag as he entered the mirrored room. He completely ignored it until he saw who it was. He recognized the lean, grunting, sweat covered body. But he didn't speak. Sebastian was almost entranced as he watched the other boy move smoothly, as if dancing a very violent dance, "Hummel?"

The tank top clad figure whipped around, "Smythe?" Kurt scoffed. "Damn, I was actually hoping to have a nice time today, but I guess I could pretend that the punching bag is you."

Sebastian grinned, "Control yourself, princess. I just never took you for the boxing type." He said, moving closer to Kurt.

"Well, you seem to have misjudged me." Kurt turned his back on Sebastian, continuing to punch the bag.

"Oh, look, I made you mad." Sebastian drawled, walking closer still.

"Oh my god, Smythe. Please go away!" He said as he landed a particularly hard hit on the bag.

"I'm not going away until you tell me why you box." Sebastian sing-songed. There was no real reason for Sebastian to actually be talking to Kurt, but he really had nothing better to do.

"Don't really want to." Kurt grunted, not bothering to look at Sebastian.

"Still not leaving." He smiled smugly as Kurt turned to him.

"Ugh, fine. I was about to rest anyway." Kurt said, grabbing his water bottle.

"Sure you were." Sebastian sat on the floor, patting it as an invitation for Kurt to sit down.

Kurt accepted the invitation, leaning back on the wall. "Well, Blaine taught me how to box, and I wasn't that bad at it, so I guess I thought it would be a better stress reliever than baking."

Sebastian snorted, "Baking?"

"Yes! I'm a stressbaker, so what? It's better than nothing!"

Sebastian held up his hands in a show of mock defense, "No need to get defensive, Kurtie." He smiled smugly as Kurt glared at him.

"Don't call me that."

"What would you prefer? Babe, kitten, prude? Stop me when you find one you like."

Kurt rolled his eyes and drank from his water bottle. Sebastian stared as the other boy threw his head back, revealing a pale strip of skin, and sucked at the bottle. Kurt caught the taller boy looking at him. "May I help you?"

Sebastian shook his head, "There is no way you're not doing that on purpose."

"Doing what on purpose?" Kurt stared at Sebastian.

Sebastian gestured at Kurt's entire body, "This. All of this. The way you just drank that what water? Normal people don't drink like that."

"How the hell am I supposed to drink?" Kurt stood up.

"Aw, Kurt, don't leave. I thought we were having fun!"

"You might be having fun, but I'm extremely creeped out." Kurt grabbed his towel. "Goodbye Sebastian." He sauntered out, hips swinging.

He definitely just did that on purpose, Sebastian thought to himself with a pleased smile.
