This is my first story on Fanfiction, I've been writing fanfiction since I was thirteen, but don't expect these to be award winning pieces. Enjoy!
"Staring Contest!" The challenge was met with silence, well, unless you counted the sound of Gwen typing out what Ben assumed was some sort of evil code on her laptop. The redhead, who currently sat across the table from him, had gone eerily quiet when their Grandpa had left for the evening. Ben was sick of it. "Gwen!" His redhead cousin groaned, then glared over the top of her laptop at him. "What do you want, Dweeb?" He put his chin in his hands, looking pleadingly at Gwen. "Grandpa's left us alone for the night, let's do something fun!" Gwen raised an eyebrow, a smirk forming. "And your idea of fun is a staring contest? Psshh. Go play with the Omnitrix, or something." She turned her attention back to her laptop. Ben was ticked, she knew exactly where his buttons were, and pushed them without mercy. He huffed, the leather squeaking as he pushed himself deeper into the cheap leather seat. He thought he knew his cousin well, but over the summer he had learned differently. He was kinda glad that Grandpa had dragged her along, with her wit and freaky magic skills, she made fighting evil fun. But she was still a stick-in-the-mud, and that really irritated him. But it drove him to what Gwen considered new lows, but they ended up getting her to unwind. He grinned as he reached for the Omnitrix on his left arm, the Alien watch glowed as he twisted the dial from side to side, the green light and the noise of the device caught Gwen's attention. "Would going Way Big in the Rust Bucket change your mind?" Ben grinned wryly, Gwen's face twisted in irritation. "You wouldn't." Ben's grin grew, checkmate. Gwen stared at him angrily, her gaze did not falter, until she slammed her laptop shut. "Forget it! I am not having a staring contest with my Freakazoid cousin!" Gwen stood from her seat and scooped up her laptop, as she turned to leave Ben pushed the dial in on the Omnitrix. As the device flashed, Gwen dreaded what would come next. Instead of a transformation, a hologram of herself hovered above the Omnitrix's dial. "Go play with the Omnitrix, or something." Gwen's eyes widened in surprise, then narrowed in anger. "How the heck did you do that!?" She demanded. "You think I'd tell you how I did it? No way, freak!" Gwen huffed angrily. "Fine, if it'll get you to stop whining!"
The two ten year old's stared each other down, silence reigned as the sun began to set. Ben was grinning cockily, Gwen raised an eyebrow while somehow managing to look disinterested. "Your eyes dry yet, dork?" Gwen's eyes narrowed. "You're not going to get me to roll my eyes at your idiocy, dweeb." Ben huffed, his eyes narrowing and his grin gone. "Worth a shot." The two were silent for a moment, before Ben's grin returned. "New rule: Loser does dishes for a month." Gwen laughed, then frowned. "Fine." Ben's grin widened. "Really? Because Grandpa was planning on making marinated slugs tomorrow, and I don't know if you'll be able to handle it with the amount of soap we have left." Gwen smirked. "Really? You know what soap is?" Ben growled, slammed his hands on the table, and glared at her. "Well, at least I'm not a know-it-all!" Gwen's eyes widened, then she returned Ben's glare. "Well, at least I'm not a loser who doesn't recognize the value of work!" Ben stood from his seat. "At least I know the value of being a hero, even if the odds are against me!" Gwen stood as well. "Well at least I am not a loser who spends more time looking for praise then actually being a hero!" Ben growled, leaning forward. "What did you just say!?" Gwen leaned forward as well. "You heard me, stink breath!" Ben ground his teeth together, his left fist clenched. "Booger face!" "Pig!" "Snort mouth!" "You little...!" It was in that moment, the two realized how close they had gotten. Gwen could smell Ben's breath, (Gross!) and Ben could smell her strawberry scented shampoo. The two hesitated, their faces drawing closer. "W-what're you-" Gwen stuttered, but she was cut off as Ben pushed his lips against hers. Gwen could've sworn she felt her Mana increase by tenfold as she wrapped her arms around her cousin's neck. The two broke apart suddenly for air, they stared each other in the eyes, both too out of breath to speak right away. When they did, it was Ben, he started laughing. Gwen raised an eyebrow, a small smile on her reddened face. "What's so funny, doofus?" Ben leaned back into the leather seat, his eyes closed and his arms behind his head. "I won." Gwen's blush faded, and was replaced with a furious shade of red. "Did not!" Ben grinned. "Did so! You closed your eyes first!" Gwen huffed as she plopped down into her seat. As her anger faded, Ben's right eye opened. "Well..." He blushed slightly. "We could always have a rematch, if you're that big of a sore loser." Gwen slowly grinned, her face a Tetramand red. "You're on, Doofus."
