Author's Note: Welcome to my first and probably only Tenjho Tenge fanfic, "Sin." Recently I've become a fan of the Tenjho Tenge series, and I was surprised to find hardly any fan fiction for it (but then again, I didn't look too hard). I've seen the entire anime series fansubbed, including the OVAs, but I haven't read the original manga so this story is based on the anime series (though I've heard that there's little difference between the two) and have just recently seen part of the official U.S. release of the series. This fic takes place shortly after the second OVA episode. Like most of my fan fiction that I've written recently, this story is shoujo-ai, but what sets this fic apart from my other shoujo-ai fics is the fact that this story deals greatly with the topic of incest (in this case, the Natsume sisters, Aya and Maya). So if stuff like that offends you, I strongly recommend you read something else. Also, the lemons and other adult situations for this fic were edited out of this version of the fic. The uncut version of this story can be found in under my alternate pen name, cbman. Well that's about it for now, let's start the story.

Prologue

She sat there her with her entire body unmoving. Her breath was short, her throat parched, and her heart heavy. Her entire being had been frozen at that moment, not paralyzed by the evening's breeze, but by the words spoken to her by her loved one.

"Aya, do you want to make love to me?" was what her lover said.

Aya did not know how to react after hearing these words, just the thought of having the one she had long adored finally say these words to her always painted her cheeks with a stroke of pink, and now, finally in reality, the one she loved had finally said it. Her body began to tremble now, scared of the uncertainty of what her loved one would feel if she were to fail in carnal embrace. It's true that the one before her had put her down in the past at times, had avoided her on numerous occasions, but it was not because they had thought ill of her, but because of their own insecurity.

"Aya, if you don't want to, I understand," her lover began to speak again. "This is something that can never be undone. After we've made love, nothing will ever be the same again. It's a really big step, one that can forever change how we look at one another. If you're happy with the way things are now between us, then we can just forget about what was brought up this night and..."

"No," Aya interrupted, placing her finger on the lips of her admirer. "I am happy with the way things are right now, but I wish to go further with you. We've been through so much in the time we've known one another, but whenever we were together in the past, you never showed me

your self, your real self. You always try to act so strong in front of everyone, always full of pride, always taking charge, but behind that facade, I always saw a deep sadness that no one else noticed. So please, if only for tonight, show me the real you. I know it's selfish of me to ask such a thing, but please, show me..."

"Aya..."

Her palms began to clasp the face of her lover, the one she had adored for so long, the one who had showed her the path to true strength, and the one she had dedicated her body, mind, soul, and heart to. Her lipsbegan to inch forward, quivering at the touch of her admirer's breath. The gap between their mouths was soon broken with the press of their lips, the skin of their mouths fitting perfectly against one another. A brush of warmth began to fill within her being, her entire body

slowly melting with every passing second. Her body began sinking, her lover's form following her lead to the futon. The moment her back met with the cotton surface, their lips began to part. The chilly air began to separate the two again, but only for a second. Another brush

of their lips soon passed, this kiss deeper than the first. Her entire body began to burn now, the flames of passion swirling inside her.

Their lips parted once more, but this time they did not meet again. Another kiss had followed, this time it was on her neck. It was followed by another, this one an inch below the one before, and then another followed. More and more kisses fell upon her neck, each one adding more tinder to the inferno burning inside her. Her arms began to take hold of her lover's shoulder in an attempt for her to catch her breath. Their eyes met during this brief recess, her reflection shimmering brightly through the irises of the one she so greatly adored. Aya gasped when their lips met with the base of her neck, her skin tenderly being pulled by the mouth of her lover. She loved how they were tending to her; so soft, so gentle, her body was craving more.

"More...," Aya begged in a whisper.

"Are you sure, Aya?" the question was raised once more.

"Yes," she nodded, "please, don't torment me any longer, Oneechan."

"Please, don't call me that," her lover said. "Call me by name. Please, just say my name, Aya."

"Maya, please, continue," she corrected herself.

For the first time she can remember, Natsume Maya's little sister had finally called her by her name. In the past she was always known as "Oneechan," not once did she ever call her "Maya." There were only two who ever called her by her name, the only two men she had ever truly

loved, her brother Shin and her former boyfriend Mitsuomi. Both of them were dead now, and to finally hear someone she deeply cared for call her by her name once more brought a smile to her lips. This smile was not one she had to fake, not a mask to hide her true emotions, but

a real smile she had not given for two years.

Heaven, bliss, ecstacy, these words did not even come close to what Aya had felt that moment. Never in her imagination did she think making love would be so passionate. The taste of her sister's lips, they rivaled the taste of the sweetest honey; the sound of her gasps and moans were as soothing as the winds, and her skin as soft as clouds. Perfect, everything was just perfect in that very moment when the physical expression of their love had finally reached its peak.

"That was beautiful, Aya," Maya said, staring into her sister's cinnamon pupils once more.

"Thank you, Maya," the younger sister returned the smile.

"I love you, Aya."

"And I love you, Maya."

Their lips met once more after, adding another small piece of tinder to the dying flame inside each of them. After parting lips once more, Aya had turned her attention upward, her eyes surveying the ceiling. Maya watched as her lover stared at the surface above them, the smile on

her face slowly melting as she saw the blank look on Aya's face. Concern immediately took over upon seeing this; Maya couldn't help but wonder what was going through Aya's mind at that moment.

"What's wrong?" Maya asked.

"I can't believe I just made love to my own sister," she answered. "Don't misunderstand though, Maya," she assured her, her usual smile stretching across her face, "I have no regrets about what just happened."

"Then what's wrong?"

"Isn't it a sin to engage in actions like this with your own family? Is it not moral to sleep with your own sister even if your love transcends the barriers of flesh and blood?"

"...I suppose it is," Maya answered, "but forbidden fruits are also the sweetest."

"Then...how do you think Souichiro-sama and the others will react when they find out about this? Will they think we're terrible people? Will they look down on us for doing something so immoral?"

"Before you can ask that, you have to ask yourself what is truly moral and immoral. We all have different views on different things; some may think that disciplining students should strictly be a parent's job, others may think that the schools have a right to do so; some may think sex should only be done after marriage while others think otherwise. These are but a few examples, Aya, so which is truly right? None of them are right, do you know why? Because the only one who can decide what is truly right and what is truly wrong is yourself, Aya. I'm not saying that you shouldn't listen to others around you, but I want you to do what you think is truly right regardless of what others' opinions are."

"I understand," Aya nodded. "...Maya, do you remember how all of this started?" Aya asked after, changing the subject.

"What?"

"I asked you if you remember how this all started?"

"...yes I do," she answered after a slight moment of hesitation. "It was two weeks ago, at school, three days after...," she stopped, a lump now in her throat. "Three days after Mitsuomi died..."

Author's Note: Good so far I hope. I know Mitsuomi didn't die in the anime, but the events that lead up to his death will be briefly explained in the next chapter. As for Aya, I'm sure we all know she's deeply in love with Souichiro in the anime series, so I'm sure many of you are wondering why she's with Maya then. I'll explain that in a later chapter because the following chapters (possibly at least the next four) will take place two weeks before the events of the prologue. Also of note, the rest of the story will be told in First Person POV, told through different characters' POV; not just Aya and Maya, but also through the rest of the Jyuken Club's as they learn about the sisters' new relationship. In later chapters, you can expect to see a few

fights, including a rematch between Maya and Isuzu. I'm aware that in CMX's translation of the manga, Aya does call Maya by her name all the time, but I'm not sure if that's the case in the original manga. But whatever, this is based on the fan-subbed version of the anime (I know Aya calls Maya "Sis" in the English Dub, but for the fic, we'll just go with 'Oneechan' like the fan-subbed version). One final note I should make is that Maya will most likely be out of character in the following chapters due to the fact that Mitsuomi died. Well, hope you

all liked it so far, review if you like, but I hate flames. Hope you continue to read this fic.
