3. My Sister And Me Have Become A Couple

“Want to have sex, onii-chan?” She beamed from ear to ear, a more genuine, passionate smile than I’ve ever seen from her before.

Her demeanor's often lethargic and tired, but all of a sudden now she was brimming with energy and joy. It caught me off guard.

Those doubts fermented in my mind felt pointless compared to her joy. I began to wonder if it was okay for me to have a relationship with her.

Normally a girl like this would be far beyond my league, and if it makes her this happy…

“Yeah.” I blurted without thought.

Wait… we don’t have condoms, do we?

Before I could ask, she inched to me closer on all fours, a sly expression on her face.

Without another word spoken she lunged at me, pressing me down onto the bed.

“You’re not going to stop me, huh~” She smirked, her eyes shifting towards my crotch. “Guess I’ll have to reward you for that.”

I quivered with anticipation, but still, if only to convince myself I'm not at fault, asked "Are you sure about this?" She gave a quick nod as she brought down her hips, making me feel a very constricting sensation.

She bled a little bit, but her face showed no signs of pain. Did she really want me this much?

She moves her hips up and down, as the wet, tight sensation proved to be too much for me, I had to force myself to calm down a little.

At least she was going to pull out, right?

She giggled softly, "Wow, you're really excited, aren't you onii-chan? Don't worry, you can finish whenever you feel like it. We have plenty of time."

In my eyes she looked like a goddess, coming before a poor soul and giving a revelation. Who cares if she is my sister? If she wants me, who am I to refuse?

Almost instinctively, I matched the pace of the rhythm of her hips, going in deeper than before, and again touched her soft breasts as she gave off a smooth moan.

"Ah... ahhh..."

It seemed at his point we were both getting close. I desperately clasped her hand with my remaining free hand and started to move harder, more impatiently. I desperately wanted to finish, no matter the consequences.

Our blush became deeper and deeper as we pounded into each other, and finally my dick spasmed, and I came inside harder than I ever came before. With extreme satisfaction we gasped for air, as she started kissing me again. I kissed back, thoroughly enjoying the sensation.

As the night went on. Our rhythmic movements became more bestial, eventually drowning ourselves in eachothers bodies. We had done it so many times...

Before the sun had truly come up she wiped away any remaining stains and put her pajamas back on. Before she left, she winked at me, saying

"You don't need a girlfriend anymore now. right, onii-chan?"

I could only smile back at her. Who would not want someone like that. But slowly as I spent more time awake in my bed, I started to question myself what I had done. What was I thinking, finishing inside her so many times? Did I really want to get her pregnant? What would my parents think of this?

Though, even amongst all these thoughts, my happiness never went away,and I only felt more excited to start out my day.

My sister being my girlfriend, huh? Maybe it's not that bad of an idea after all.
