Because

After about 5 minutes of silently contemplating my miserable existence, I heard your footsteps slowly approach. I was too tired and broken to try to get away, so I just sat up straight and let you sit down by my side as shame washed over me.

"Hey, sis."

"I'm so sorry big brother, I'm so sorry!"

I tried to get out more words but I couldn't stop **** on them. You wrapped an arm around me, whispering "Shh, it's okay, nothing's wrong," into my ears.

I put my arms around you, probably a little too tightly, and cried out as you tried to comfort me. One hand of yours gently pet my head as I failed to pull it together. Even your arms weren't enough to stop my self-loathing this time.

Eventually, I asked, "How did you find me?"

"You've been coming to this park nearly every day for the past month. Wasn't much like finding Waldo, was it?"

"I guess not..."

You cuddled me for a little bit more before whispering, "Let's head back home, okay? It's too cold out here to cuddle."

"I... I can't go back."

"What do you mean you can't go back?"

"I don't belong in your apartment, I'm not good enough to live with you. I've fixed it, though. The petstore will be picking me up in the morning, you won't have to see me anymore. I promise."

Suddenly, you went from attempting to comfort me to having a mixed look of fear and maybe even anger on your face.

"No, sis. Don't you dare. You can't do that."

"Why not?"

"Because, you just can't. You can't leave me like that, not for this dumb of a reason!"

"But I've been so terrible to you, you've had to work so much harder to pay the rent and buy my food, how could I keep forcing you to do that? I'm a horrible sister."

"No, you're not!"

"I've made you hate me."

"No, you haven't! I don't care if you're making me work more, or if you're acting weird, or if- if you want me to be weird. None of that matters."

"Why would you not care?"

"Because... Because..."

You couldn't think of any way to put your thoughts into words, I guess. You took the only action you could think of. You pulled me as close to you as you could, and you placed your lips on mine.

Fireworks! Butterflies! Lightning! Other phrases that could be used to describe you kissing your little sister!

I was so confused for a moment, I didn't even understand what was happening. It's as if I had forgotten what a kiss was, but that couldn't stop me from enjoying it! I whimpered at the feeling of your lips against mine, they were so perfect. I felt you start to open your mouth while you were still against me, and that gave me the opportunity to push my tongue in-between your lips. You went rigid for a moment, before relaxing as I enjoyed the feeling of us french-kissing for the first time. The electricity running through my body was so amazing, I had a hard time sitting still. You still had an arm around me, letting you caress the back of my head with your hand.

Eventually we parted with a gasp.

"Wow, sis, I-"

I couldn't let you continue, I dove in and started kissing you again. You pushed me back a little and rushed out a "Please, I need air!" with a laugh.

"Sorry," I mumbled with a blush, though I doubt you could see it with how flushed my face was already.

We laid back a little and snuggled up again. I had so many thoughts and so many questions, but I was ecstatic enough to let it be for the moment.

"Okay, for real now, it's too cold to be out here. Let's go home, okay?"

With a nod and a smile from me, you took my hand and walked us home.
