"Kat? I'm just going to Grace's house, tell mum where I am, ok?"
"Who do you think I am? Bloody Postman Pat? Tell her yourself!" I stuck my tongue out at her and walked out of the door. I knew she was only messing around. She was just doing her job as my annoying little sister.
As I took the five minute bus ride to my girlfriend's house, I began to think about Katrina. She was thirteen years old, pretty much bang in the middle of puberty, but she hadn't once mentioned any boys. I didn't know much about girls of that age, but I knew that as soon as they started high school practically everything they said had the word "boy" in there somewhere. A random thought crossed my mind. Perhaps she didn't like boys at all. I laughed and shook it out of my mind. She'd probably get a boyfriend when she was ready.
When I arrived, I jumped up the five concrete steps and knocked on the door. After a minute or two, Grace answered. She was wearing a plain black top and a pair of skinny jeans. She looked as beautiful as she ever did.
"Hello stranger!" she said, before grabbing me into a rib-splintering hug. I pretended to choke, and she laughed and let go. "So what brings you here?"
"What do you think? I obviously came to admire the scenery of your street." I sarcastically replied. She smiled, then pulled my face closer to hers. I grinned and kissed her lips gently. She kissed me back for a couple of seconds, but then she pulled away and sighed.
"Grace? What's wrong?" She sighed.
"You remember Chris, from high school?" I nodded. "Well we went out for a few months back in year 9 and he was the first boy I ever fell in love with. He's come back recently and told me he wants to see me again." My heart plummeted.
"Can't you just tell him you're with somebody already?" She shook her head.
"I don't think it's as easy as that. I think... I think I still love him." she whispered.
"Wait. Does that mean... are you breaking up with me?" I choked out. She didn't answer for a while.
"I don't know. I love you, but I love him at the same time. I just can't decide between you." A tear formed in the corner of her eye. "You'd better go. I'll only end up making you upset while this is going on." I turned away, not letting her see the tears that were threatening to pour down my cheeks.
I sat in my room alone that night, thinking through what Grace had said. We'd been together for four months, and I'd assumed she was happy. But now this Chris kid had come along and was threatening to ruin it all. A loud knock on my door interrupted my thoughts.
"Come in!" I shouted. The door opened, and Katrina walked hesitantly in.
"Hey Stef..." she said nervously as she sat beside me on the bed. "Renee told me about what went on. I just want you to know, if she DOES choose him over you, it'll be her loss." She smiled uneasily and put her arm around my shoulder.
"No problem, bro. Just remember: if she does dump you, I'll be there for you, 100 per cent." My phone beeped on the cabinet. She looked at me. "Do you want me to get it? Just in case it's her?" I nodded my agreement, and she read the text message. A worried look appeared on her face. "I'm so sorry..." She hugged me tightly. After a few seconds she pulled back and studied my expression, to make sure I wasn't planning on doing anything stupid. As she did, I began noticing things about her that I never had before. How pretty her chocolate brown eyes were. The way her light brown hair glinted when the light touched it. And her lips... I shook my head quickly. She was my SISTER for god's sake! Why was I even THINKING about this? She looked at me again, concern in her beautiful eyes.
I suddenly realised I couldn't fight it anymore. I had to just let it happen, and cope with the aftermath. I closed my eyes, took a deep breath, and kissed Katrina's soft pink lips gently. I could feel her initial shock, but then she relaxed into it, and I felt her lips move into a smile as she started to kiss me back. She pulled away quickly and sighed.
"I love you, Stefan..." she whispered. "And not just as a brother..."
"I know. I love you too Katrina." She smiled, and pulled my lips towards hers one more time.
