Karen Succubus

As I gazed at my little sister's stark red face several thoughts spun through my head. The first being how it had come to this, how I had come to see my little sister as a woman. I'll skip the rest as they will be secrets I will keep locked away for the rest of my natural life, how ever long that may end up being.

Karen lay below me, panting and moaning as thrust into her orifice with all the strength I could muster. With each pass her breathing became faster and faster until it almost matched the rhythmic creaking of the bed springs below us. As the bed below us creaked two and fro, a measure of fear formed in the back of my mind. A long time, ago, when me and Karen had first begun our illicit affair, my other little sister had walked in on us with knife in hand and a confused look on her face. But, before someone could yell "Incest?!", we had been able to explain away the incident as a conflict between siblings.

"Onii-chan... More..." She gasped between moans as she twisted and clawed at the bed's sheets s waves of pleasure surged through her well toned body. She was dressed in her usual yellow athletic jacket half and pants, notably if only because they were clothes meant to be drenched with sweat and served that purpose admirably even in moments like these.

A flip had been switched in my head by Karen's words. Normally the word "Onii-chan" held no power over the hearts of men, but after years of abuse at the hands of the authors of various erotic periodicals , it has gain an erotic quality that was undeniable as long as someone fit directly into the demographic that kind of literature was targeted at. In the end, no man could resist those words, not even coming from their little sister. Anyone who said otherwise was a dirty liar.

"As you wish, little sister~"

Readying my things once more, I plunged into her wet tunnel with great fervor and speed. My heart beating at the speed of sound, I didn't know how much more I could take. At any second I could burst and cover my little sister in an awful liquid. Despite her being my little sister... Karen was simply to perfect to ignore.

Now when I say she was perfect, I don't mean in the same way that Hanekawa is perfect. Where as she possessed the trifecta of intellect, personality, and huge breasts; while Karen possessed an athletic flair and toned body that could only be be attained by those who had devoted their lives to physical fitness and a cheerful personality that complimented the rest of her perfectly. Her breasts were also nice.

But the fact remained that she was my little sister. True, I had consumed enough erotic literature that dwelled on the subject. But that of thing just doesn't happen in real life or at least I thought that until a simple test of physical endurance had turned into an erotic situation worthy of pornographic comic's bearing titles like "My little sister can't be this Erotic!" and "Let's have fun with little sister (in bed)." In summery, I blame Karen for all of this. Not that I'm complaining.

"Oniiiiiiiiiiiiiii-channnnnnnnnnnnnnnnn...!" Karen once more moaned.

The counter in my head moved forward another tick.

Like many things in life, things with Karen often came in threes. In this case it usually took her saying, calling, or moaning "Onii-chan" three times before I lost all control and set upon her like a wild beast, the mixture of eroticism, taboo romance, and purity that made being with Karen so appealing combined to make me want to take all of her. That had happened the second time we were together like this and resulted in a wild storm of groping and moaning that would have gone down in legend, that is it would be if I could recall everything that happened that night.

"Say it again~" I said with an evil smirk as I poised myself for a third wave of attack.

"I want it Onii-chan, put your thing in me..."

I will note here that word "thing" used in this context is referring to exactly what you think it is.

The counter had reached three and as it did I removed all of my limiters, this was it. As if reading my body language, Karen grasped at the sheets below her, bracing herself from the sheer force I would soon rain upon her from above.

"Brace yourself, Karen! This is it!" limit reached, I once more I struck into my little sister, pushing deeper into her until she could feel it in her soul. At the same time my hand began to wander, groping at Karen's small yet perky chest. Unhindered by weight nor the force of gravity, Karen's chest existed in a near perfect state fostered by excellent genetic and her habit of running the equivalent distance of three marathons a week. While not as soft or pillowy as say, Hanekawa's amazing pair, but were more then enough to awaken my fighting spirit.

On the other end of things, my assault was enough for Karen to grip the sheets and twist back and forth as her body tried to contain all I had given to her. Accompanying it all was a series of moans and pants unlike any I had heard in the past. Her body drenched with enough sweat to render her cotton shirt slightly see-through, it was an amazing sight to behold. Even if I lived to be 500, I would not forget the look of ecstasy painted on Karen's unadorned lips.

As we both reached our peak, he time for a climactic act had finally come. Calling upon all of the energy stocked within me I...

"I Love you, Onii-chan..." Karen groaned, interrupting my finishing move in the process. Through the sweat and spittle of an hour's worth of intense activity she had managed to render me speechless.

My mind reeled as my body ceased any and all erotic actions. It was the words I had been dreading since we had began all of this. It meant that the bond between me and Karen had become something other then a brother and sister who played once in awhile because they were bored and there was nothing on tv because it was the weekend and TV executives expect you to be outside like a normal human being.

Withdrawing the tooth brush from my sister's mouth, I slid off the bed and hit the ground with a loud thud.

"What's wrong Onii-chan?" Karen, still drenched with sweat, had laid down on the bed and now hovered over me with a quizzical look on her face.

"Why did you say that...?" I said, unable to look her in the face.

"Because I do love you!" Chipper as ever, her endurance was amazing.

"How though, like a brother or...?"

"Hm, if your going to make me choose, I guess I'd like to say that your boyfriend!"

Porn had not prepared me for this. I'd seen every scenario in the book, yet Karen has still managed to catch me off guard.

"You want to be my girlfriend?"

Ignoring the moral implications of dating your own sister, put yourself in my shoes for a moment. A nearly perfect girl has told you that she wants to be your girlfriend. But, you already have a girlfriend who, despite putting the tsun in tsundere, was otherwise completely awesome. Think about it for a minute. It sucks, doesn't it?

"Yup!" My sister cheerfully quipped.

"I already have a girlfriend, you know that."

Her name was Senjougahara, a classmate of mine who had, for a time, been afflicted by a crab-shaped god that had stolen her weight, rendering her light as a feather. After I had helped to free her from the oddities curse, we had began a relationship that, while it had moments that involved being tied up, beaten, verbally abused, cut with school supplies, and more things that I've chosen to forget for the sake of my love for her, fills my heart with a feeling described in popular works of questionable fiction as Doki Doki. No matter how cute Karen was, I could never leave Senjougahara 's side. Not now, not ever.

Maybe.

"Then you should just break up with her!"

"It's not that easy..."

Karen rolled onto her back and had begun to stroke at a strand of hair sticking up from the back of my head, mimicking the motions of an act that would not be out of place in a couple's bedroom. It wasn't the act itself that effected me, but rather the suggestion of something very, very, dirty it carried

I wondered where Karen had learned to do that. A single thought came to mind... I should find a new hiding spot for all that porn, just in case.

"But Onii-chan... you always play with me when your bored. You should take responsibility for making me feel this way!"

Though a the portion of my brain that lit up when experiencing pleasure was currently in control of my being, enough rational thought remained for me to respond without cooing like a song bird.

"Stop that! Your only making this harder for me." I shook my head to free my hair from her probing hands. "Besides, what do you even want me to do?"

"Promise me you'll think about it~" Karen's tone had been oddly seductive as she continued to play with my hair. From her movement of finger to the look in her eye, every bit of Karen showed she was completely serious about all of this.

Despite my best efforts to the contrary, Karen quickly snatched my hair once more. Taking it in the palm of her hand once more. She began to Increase the pace of her action with each pass. Though it was only hair that she had taken hold of, it was quickly becoming to much for even my jaded heart to handle.

"FINE! YOU WIN." I rose with a shout, throwing Karen from her position on the bed and hurtling towards a nearby wall. In perfect form she managed to bound off and land firmly on her feet. If in some strange alternate reality Sister tossing was an Olympic event, she would have won the gold. "I'll think about it, give me..."

How long was enough time to know if you loved your little sister as a woman? Most fiction on the topic suggested it only took a period of realization followed by days of awkwardness, angst and soul searching, followed by burying your feelings until you do something awful [sniffing their panties, etc] and finally coming to terms with your feelings and becoming a couple, which at point you live a life of constant fear of being caught... Why was I considering this again?

Look backing at Karen, I found my answer in her sharp eyes and charming smile.

"Give me three days." I said in a monotone. It seemed long enough time to weigh my options.

"Ok, Onii-chan. I'll be looking forward to your answer."

Karen sprang off the bed and walked off in such a manner as to accentuate her best features.
