A/N: I got distracted from my CSI fic even though I said I wouldn't and I just had to write this! The song featured is Chemicals React by Aly and AJ, it just fits them so cutely. Enjoyyyyy.

It was early evening by the time Austin joined Ally in the practise room, they'd both been busy all day, Ally with running the shop whilst her father was out of town and Austin with keeping up with Dez, tired was definitely an understatement for what they were both feeling by the time they sat down to discuss Ally's new song. She had written it late last night whilst thinking about someone or to be a bit more specific, her feelings towards that certain someone. Their image had caused a spark inside Ally as she ferociously wrote down these lyrics, pouring her heart and soul into this piece which she hoped would be Austin's first mega hit, one that she hoped would get him signed and on the map in the world of music.

"So, how about it starts like this?" Austin placed his fingers on the keys and softly began to play a sweet tune on the piano, starting slowly before he began to increase the tempo as he hummed the song Ally had just started writing for him. He looked at her from the corner of his eye, staring at him so intently, a small smile on her petite face which was now mirroring his. She was so talented; she had only begun to write this song yet it fit so perfectly to him, to his voice. She was perfect at this; moulding words into a shape, into a structure which would help him capture his inner talent, help him channel his thoughts and feelings into a lyrical matter. Sometimes, Austin wished he had her ability to write such beautiful songs and sometimes he felt guilty that he was keeping her trapped under his thumb, writing songs for only him not being able to sing on her own, the only thing that made him feel guilty about that was the fact that he liked it, he liked having her around him constantly, writing for him, helping him and just being there for him. He stopped playing and rested his fingers on the keys, tilting his head in her direction slightly, "What do you think?" He watched as her lips parted slightly, their cherry red colour teased him, tugging at his heart strings.

"It was good, exactly how I pictured it. The slow start is good but maybe we could keep it like that? Have it as your first soft melody?" Her voice was timid as she raised her suggestion, Austin was known for his pop style, his enticing beats and fast moving songs which raised peoples moods and had all the girls screaming but Ally wanted this one song to be different, she wanted it to have feeling, she wanted it to be Austin's first song that people listened to and felt a connection with him, felt like he was trying to speak to part of them and tell them that feeling is good. Their eyes met for a moment and Ally hesitated, wondering if she should take back her earlier statement but she decided to instead, show him what she meant, "If you played it slowly, all the way through, it would have more meaning to it right? More emotion, like this, watch." Ally placed her hands where Austin's were moments ago and she began to play the same tune, this time a little slower and she sang along.

"You make me feel out of my element

Like I'm drifting out to the sea

Like the tides pullin' me in deeper

Makin' it harder to breathe"

Her voice was gentle and sweet and it mesmerised Austin in ways he really didn't know could happen. He watched her as she closed her eyes, putting her heart into the song, into those words and he felt the urge to reach out and touch her, caress her face, do something to show her that he understood how she felt. His eyes trailed her face, slowly following the lines of her cheek bones, her jaw and it wasn't until now that he realised how perfect she truly was, not just in her musical talent but in her flawless personality, in her loveliness and in her outstanding way of seeing the true beauty in everything around her. Her chestnut curls cascaded past her shoulders, shining in the dimming light from the window in the practise room and Austin found himself moving, his hands being gently placed on top of Ally's and his voice mingling with hers in a magnificent melody.

"We cannot deny, how we feel inside

We cannot deny

Were you right, was I wrong

Were you weak, was I strong, yeah

Both of us broken

Caught in a moment"

Ally could have sworn she had actually stopped breathing. Was this actually happening? Were she and Austin really singing a song she wrote about her feelings for someone together? Ally opened her eyes and looked at him; she could feel the passion in her own voice as she sang her song, their synchronised words mixing together like they were meant to be doing this. What were they doing? Were they just singing her song together because it felt like more, the butterflies in Ally's stomach and the flutter in her heart told her that it was definitely more. Ally was suddenly aware of every inch of her body; it was all on fire from Austin's touch, from their legs resting next to each other, their hands lying on top of one another, their arms brushing together, folding together and their heads, their faces inches apart.

"We lived and we loved

And we hurt and we jumped, yeah

But the planets all aligned

When you looked into my eyes

And just like that

The chemicals react"

They both stopped in sync, their eyes locked, their hands entwined together, their rapid hearting beating together. Ally's breath hitched as she felt Austin lean in towards her slightly, she wasn't prepared for this. Her lips parted as he took one of his hands off hers and began to slowly trail it up her arm. Ally felt her heart flutter and the butterflies in her stomach went on a rampage, knocking a nauseous feeling into her system. She lifted her free hand to the side of his face and pushed the stray blonde strands of hair away from his eyes, "Just like that." She smiled softly at him before getting up off the piano bench and walking away from him, away from their moment.

Austin sighed "Yeah, just like that."
