———————————————————————————
Aria sprinted down the stairs after hearing a knock at the door. Finally, she thought. The pizza is here. She grabbed her purse from the side table in the hall and opened the door. But she was surprised when the pizza man wasn't at her door, it was a friend from school. Well, 'friend'. She started up at the Greek god standing in front of her, he smiled at her while she looked up at his brown curls which slightly covered his hazel doe eyes.
"Hi Aria" he said, smirking at her. She couldn't help but smile back.
"Hey Dean, hows it going?" She said, silently cursing herself for not coming up with a better conversation starter.
"Hi, it's Sunday tomorrow" he started.
"Yes, I'm aware of that considering today is Saturday" she laughed, as she watched him blush, Gosh that boy was adorable, she thought.
"Yeah, no, sorry, umm" oh my gosh was he stuttering? "I was wandering if you wanted to go out tomorrow?" He said, trying to look her in the eyes s.
"Yeah, is love to, text me when?" She asked.
"Yeah course. See you then!" He said, leaving.
"Bye" she waved, shutting the door and turning round to reveal her smirking brother at the top of the stairs. Crap.
"Sooooooo, that wasn't the pizza guy" he laughed, making his way down the stairs. He stared at Aria expectedly whilst she glared up at him not saying a word. "Who was that?" He finally asked.
"A friend from school" she replied, putting her purse down and walking into the family room hoping to avoid any further questions.
"Ahhh, right. Who do you know him?"
"He's in some of my classes"
"Do you like him?"
"What? No!" He laughed and stared at Aria. "What Daniel?" She said staring back at him.
"Oh nothing, it's just, you always play with your hair when you lie." He smirked folding his arms. Aria immediately put her hand to the side, away from her hair. Damn it. Why was he always right? She thought.
"So, do you like him?" Aria looked away, blushing hard at the question, but of course, not before playing with her braids. "Awwwwww, does my baby sister have a wittle cwush" he teased, using his baby voice. Aria blushed harder and refused to look at her brother.
"No" she said refusing to look at her laughing brother in the eyes.
"Aww, come on, what's his name?" He said poking her sides, trying to get her to speak. Aria dodged as best as she could his poking fingers, but she couldn't get the words out and her small hands compared to his massive ones were no match.
"Dahahahnnieellll, stooahahhapp" she weakly giggled, falling back onto their sofa and pushing his hands away from her sensitive sides.
"Whaaattttt???" He dragged the word out. "I just wanna know who he is?" He laughed continuing to dig his fingers into her upper body. At this point Aria couldn't hold in her laughter.
"AHAHHAHAHAHAHAHAHHA, DAHAHAHANNNIIEEELLLLL, NOOOOOOOOO, STAHAHAHAHAHAHAHPPPPPPP"
"Hey, all you have to do is tell me! What's his name?"
"IMMMMM NAHAHAHTTT TELLLIINNGGGG YOUOUUUUUUUUUU, AHAHHAHAHAHHAHAHAHHAHAHAHAHAH" she laughed and thrashed around in his brothers grip but she was cornered in the sofa and she could do nothing to escape.
"Come on, at least tell me his name!" He said spidering his fingers up and down her midsection knowing from experience it would make his sister go mad.
"IIIIIIOI CAHAHHAHAHAHAHNNNTTTTTT, STAHAHAHAHAHHAHAPPPPP AHAHAHAHHAHAHHAHAHAHAHHAHAH"
"Well if you're not gonna tell me....." he trailed of and then lifted up her already riding top and started attacking her bare stomach. This seemed to to get Arias attention because she screamed of laughter trying to wriggle out of her brothers grip.
"Ooohhh, someone's ticklish" he teased, giving light touches up and down her sides. "Does this guy know your ticklish?" He laughed. Aria shook her head, barely able to speak, let alone strong together any sentences. Her breath had been taken away (literally) and she was currently blabbering demands to Daniel, which he happily ignored.
"Come on sis, just tell me his name!"
"NAHAHAHAHHAHAHAHHAH, I CAHAHAHAHHAHAHHAHAHHAHAHNNMTMTTRTTTTT"
"Very well then" with that, Daniel stuck his finger into her belly button, which Aria bucked up and down in silent laughter. Nothing was coming out of her mouth apart from the occasional scream. Tears were coming down her face from all the laughter, as she attempted to push Daniels hands off her, but she failed from her weakness. Daniel, sensing she was probably going to pass out if he didn't stop anytime soon, slowed his fingers down so she could actually breath.
Aria glared up at Daniel, even though he couldn't help but laugh.
"Your mean" she said slapping his shoulders, despite that doing nothing.
"No I'm not, you love me" he said fluttering his fingers around her neck. "Why don't you tell Dean this little secret of yours?" He asked cheekily.
"How did you-?"
"Oh, you mean his name? Yeah, I heard you say it when I was spying on you from to top of the stairs" he grinned innocently.
"So what was all of that then!?"
"Eh, just wanted to torture you" he laughed. Aria was this close to knocking him out straight but luckily he was saved by the bell. And this time it was the pizza man.
