A/N: Thanks for all the support! If I haven't done your request yet, don't worry! I updated the form (Chapter 1) so it's more clear for everyone! To those of you who maybe had too long of a plot or I wasn't comfortable with writing, please feel free to make another one after reading the updated form!
The water licked at your heels as you ran from the incoming tide, towards your boyfriend. Sea water rolled down your stomach as you made your way closer to him.
"Hey Cas!" You smiled and pressed your lips against his cheek and gave him a wet kiss, when you pulled away you found his smile strained. His eyes glinted as they held something behind his deep blue eyes. Rage? Fury?
"Cas, What's wrong?" You dropped the smile and your brow creased with worry. Castiel looked at you and shook his head, brushing it off. You were about to protest when he leaned forward and pressed a gentle kiss against your lips, when he pulled back, his eyes masked whatever he was feeling. You opened your mouth to say more when two muscular guys walked by, looked you up and down, and whistled.
"Damn, you lookin' fine girl!" One of the men called to you. You blushed and looked down at your new swimsuit, it was a red, sleeveless, one-piece that fit you in all the right places. As you were bringing your eyes back up, you noticed Castiel's hands were clenched into fists, and upon looking at his face, he was no longer smiling.
"Cas...?" You slowly questioned, but he turned on his heels and walked away from you. You ran up and grabbed his shoulder, twisting him around to face you. Your heart clenched painfully as you saw sadness behind the anger.
"I don't understand this feeling Lily." His eyes cast downwards as more men walked by, taking a double take at you.
"What are you..." You trailed off as realization hit you. Jealousy. A laugh bubbled up in your chest as you pulled him into a hug, which he stiffly returned.
"Aww, poor Cas is jealous!" You mocked as you erupted into giggles.
"I'm not jealous! I just don't like how they look at you!"
"That's jealousy Cas." You took shallow breaths, trying to recover from your laughing fit, before pulling back and looking at your clueless boyfriend.
"Castiel, those guys are just flirting! I only love you! No douche-bag is going to change that!" You planted a loving kiss against his lips, wrapping your arms loosely around his neck. When you parted, Castiel looped his arms around your waist and smiled.
"I love you too. But if another guy looks at you like that, I might have to punch them, okay?"
Another laugh spilled from your lips as you nodded, kissing him again.
"Okay."
A/N: So Lily, hope you enjoyed! I think it's a bit shorter than my other requests, to which I apologize! Also, this was the swimsuit you were wearing: /ltekeqc
Thanks for your request,
Cass
