If the idea of Lightning and Serah together bothers you in ANY way, don't bother reading this. I don't want to get flamed for people hating the pairing. I laugh at flames like that simply thinking… "If you don't like it, why did you read it?"

There will be romance and hints at sexual scenes. Even I, in all of my strange writing habits, can't bring myself to write out a whole sex scene between two sisters…not yet anyway.

I figured I'd go ahead and post this since Wedding Date has one more chapter to go and I'm just about done with it. This story, I'm up into chapter 3, it probably won't have as many chapters as Wedding Date...I see it getting to 5, maybe 6...we'll see how it goes

Unbreakable Bond

Chapter 1

The first time was nearly ten years ago. We were both so scared. It started out as just an innocent game of exploration. Serah couldn't sleep one night and crawled out of her bed and into mine. She was 11 years old, I was 14.

"Claire, I can't sleep. Can I sleep with you?"

I smiled before lifting up my fleece blanket, offering her the spot next to me on the twin sized bed. "Why can't you sleep?"

"They're making so much noise." She was referring to mom and dad. "What are they doing?"

I shifted to roll onto my side to look at her. "They're having sex Serah."

"What's…sex?"

"It's a way two people show each other how much they love one another." It was all our parents had ever told me about sex.

I glanced across the living room. Serah had fallen asleep on the sofa. I couldn't help but to smile. She had grown into such a beautiful young woman. I wish some days we could go back to that time. I turned the page in my book to continue reading while my mind wandered again.

"Serah!" I turned my head to bite my pillow. Her hand instantly pulled away. Just as quickly as it vanished, I missed it. Between shallow breaths I cupped her cheek and kissed her.

We were both too young then to realize it was wrong. It may have been wrong, but it felt oh, so right. Sadly, it didn't last forever. I should have known. It was too good to be true. Dad charged into our room one night when Serah yelled in pleasure. He thought she hurt herself. I was 16, she was 13.

We both knew by then that it was wrong. We tried to stop it but the desires were too strong. From the night dad caught us on we were separated. Not allowed near one another unless a parent was there.

18 years old, I became both a sister and a mother to Serah. Our parents both died in an unexpected death. We were left to brave the world together. Just her and I. We moved from the home our parents owned to a small apartment. I immediately enlisted in the Guardian Corps. It was a way to support Serah as well as forget the pain of losing our parents. It was also when I adopted the name Lightning.

"But Claire you promised! You promised you'd be here for dinner!" There were tears in her eyes. I couldn't bring myself to look at her. The very moment she shed a tear in my presence, my heart melted.

It was true, I did promise I would be home. It was just another broken promise to add to the pile I would never be able to dig myself out of. "I know…"

"Stop making promises you can't…or better yet…won't keep…Lightning!"

The first time she called me by my chosen name. And it came out of rage. It hurt to be near her. It pained me so much. A week or so ago she mentioned the one word that brought my world to a crashing halt. 'Boyfriend.' One word. Nine letters. In my absence Serah had gone and found herself a boyfriend. "I've been so-"

"-busy. I know. You're always too busy. Too busy to even say bye in the morning. Too busy to even hi when you get home in the evening. Too busy for ME!" Tears were streaming down her cheeks at that point. "Why won't you spend any time with me Lightning?"

"You wouldn't understand Serah."

"That's never stopped you from telling me things before. Try me!" Everything she said, or, better yet, yelled, was dripping with rage.

I looked into her eyes, quickly closing the gap between us. My heart pounded against my chest, desperately trying to escape. "You want to know?" My words were harsh and cold. She only nodded. She never did back down from me. I took a deep breath, bracing myself for any kind of response she may give me. I crashed my lips against hers. Only for a few brief moments though. "That's why I can't be around you."

"Claire?"

I felt my should being nudged lightly. "Hm?" I couldn't force my eyes open. I was rather enjoying the dream of that day I was starting to have. The dream of the rough, passionate, lustful…

"Claaaiirrreee…" Her warm breath against my ear didn't help.

I gasped softly and whimpered her name. My eyes shot open. The book was no longer in my hands. Damn my neck hurt. "What time is it?" I groaned while rubbing my sore muscle.

"Dinner time." She took a few steps away from me, toward the kitchen. "You were dreaming about me again." She grinned at the instant blush on my cheeks.

"I was not."

She suddenly stopped in the middle of the doorway and turned to look up at me. Five words. Five simple words my heart and mind have been so eager to hear over the last four years. "I broke up with Snow."
