Sam was breathing heavily, sweat dripping down his forehead as he ran shirtless. It wasn't very often that the motels the three of you stayed at had a gym, and he was trying to make the most of it. And he was trying to blow off some steam in a different way than just hiding in the shower to touch himself and think about you. God, you were just…all consuming of his thoughts recently. There wasn't a single thing he wouldn't do for you, do to you. Sam wished he could just be more like Dean and hit the bars to find a girl but dammit he couldn't. He just wanted to cling by your side and do everything with you. Dean kept teasing him for following you around like a lost puppy, even sitting at your feet sometimes to talk to you. Sam huffs as he hits the fifth mile, turning the machine off. He uses a towel to wipe the sweat from his damp hair, running a hand over his face. He hears a tiny gasp behind him and immediately jumps, hazel eyes wide as they meet yours.

"I..sorry Sam..uh…I was just looking for you."

You blush, looking away quickly. Holy shit. Was he making you flustered? Sam tries to hold back his grin, giving a little smirk instead.

"Yeah? You need me?"

His words send another fresh wave of heat over your skin, making you hot and cold at the same time.

"Yeah. My snack got stuck in the vending machine."

You respond quietly, having almost forgotten what you'd come to him for. Those abs…those biceps. Jesus, you wished he'd just pin you down and-

"I'll get it out for ya, honey."

Sam says easily, looking for his shirt.
