Chapter one

"Hikari, shouldn't you go to bed?"

Hikari, who was laying on her parent's sofa, turned towards her mom and replied back.

"Don't worry, mom. I'll be going to bed here soon."

Yuuko Kamiya just sighed as she gave her daughter a kiss on her forehead.

"Just don't stay up too long, K?"

Hikari just smiled at her mother and nodded. Yuuko smiled back, turned off the lights in the living room, walked into her bedroom, and closed the door. Once her parent's bedroom door was closed and the light turned off, Hikari just sighs out loud as she looked at the clock.

10:45 P.M

"What time should I do it tonight? One, two-o-clock?"

Hikari turned her attention towards her older brother Taichi bedroom door. He had already gone to bed about 15 minutes ago. Due to soccer practice in the morning and the fact that he had multiple school test today, Taichi would have probably fallen asleep as soon as his head hits his pillow. Yet, here was Hikari, laying in the dark. Hikari brought her legs into her chest as she hugged the sofa pillow to death. Placing her chin on the pillow. Guilt already showering Hikari.

After all, tomorrow is another school day. Despite the fact that she'll have a restless sleep, deep in her mind, she would rather have a restless sleep than a peaceful sleep. Cause at what cost would her have to pay, to have a peaceful sleep? What portion of herself would she lose just for that? Even though she had already gotten at least a month's worth of peaceful sleep. Sleep that wasn't focus on her lustfulness towards the object of her desire. What cost did she paid for that?

Hikari turned her eyes on the clock.

11:25 P.m

"It's getting late. I shouldn't do it tonight. I should just head to bed right now."

"But then how would you sleep?" A voice whispered in her ear. A voice eerie similar to her own. "After all, for the past month you've been planning, experimenting. Knowing the limits of how far you COULD go. All just so you can sleep peacefully."

Sitting up on the sofa Hikari buried her face in the pillow. Guilt, weighting heavier than normal, on her shoulders.

"But this is a mistake. I shouldn't do this."

"But haven't you been sleeping much more soundly when you DO, do it?"

"That doesn't matter anymore!" Hikari turned towards Taichi's bedroom door. "I have already betrayed his trust. And if he sees me, I don't think my heart could take it."

The voice just laughed. "But your heart yearns for his. Your body CRAVES for his. After all, how many times have you masturbated to the picture that you keep hidden under your bed?"

Hikari quickly looked towards the floor. Pushing the pillow off her lap she covered her ears and closed her eyes. Hoping that by doing so, it will stop. Just stop.

"Not listening. I'm not listening to this!"

"Oooh, but you are." Hikari felt two hands placed themselves on her shoulders as the voice continued. "After all, you love him, do you not?"

Hikari eyes snapped wide open, as tears threaten to leave her.

"You see. You love him. You love him sooo much that it hurts. Which is why you need this. You need to DO this, tonight. Otherwise, you might end up doing something a lot worst."

"No! I made up my mind. I'm not doing this and that's FINAL!"

A small beep caught Hikari's attention as she turned towards the clock.

1:00 A.M

Laughter echoes around the room as Hikari just stared that the bright red numbers.

"I see. Very well then."

Hikari couldn't believe what she was hearing. Was reasoning winning tonight? Hikair didn't have a lot of time with her train of thought. For she was already standing up and walking towards her destination.

"Onii-chan." Hikari whispered out loud to herself.

"What am I doing?"

Hikari stood outside of her brother's bedroom door. Did she come here subconsciously? Or was this deliberate? Her eyes widen in shock, as her right hand placed on Taichi's door handle. Reasoning was supposed to win tonight, right? Slowly, she twisted the knob and Hikari slowly and quietly opened her brother's bedroom door. Soft, steady breathing can be heard from her brother as he slept. Stepping inside, Hikari quietly closed the door. Then slowly, very slowly she walked to Taichi's bedside. Once there, Hikari just stood there silently. Watching her brother sleep caused certain emotions to stir inside of her. Emotions that made her feel hot and bothered. Emotions that made her feel guilt and shame as she stared at her brother.

With her right arm, Hikari grabbed her pajama top above where her heart beated loudly in her ears. Her face turning deep shades of crimson as she stared down on Taichi. Confusion, started to probe Hikari's mind as to wither she should stay or go. All the while her heart aches for the one she loves the most.

"Onii-chan."

As Hikari's grip on her pajama top increased, so did her voice.

"Go on. Do what you came here for."

Hikari shook her head, tears threatening to leave.

"No, I-I can't. Please." She begged. "Please don't make me do this. N-Not tonight. Please."

"Oh, Hikari." Hikari felt arms hug around her shoulders. "You know for a fact that you MUST do this. This is just like any other night. No one's around to judge you. NO ONE is here to STOP YOU."

Hikari's body started to move after that last statement. After all, it is true.

"No one is HERE to stop me."

Hikari slowly took the blanket, that was covering her brother, off of him. Then, just like what has happened for the last several nights, Hikari got on the bed. Hovering over Taichi, Hikari just stared at his sleeping face. Her brother looked so peaceful, completely unaware of what was going on. If only he'd open his eyes, maybe something could change. Hikari gently rubbed his left cheek, lovingly.

Hikari started to move her body down towards her brother's lower half. All the while, Hikari kept a stern look at her brother's face. Just to see if, maybe, he'd wake up. All the while, her heart beated hard against her chest. A moment later, Hikari reached her destination, as she grabbed a hold of her brother's boxers that he wore to bed.

"SOMEONE, PLEASE!" Hikari's continued to breath heavily, as she then pulled down her brother's boxers shorts. "STOP ME!"

Taichi's hard, pulsing member was freed from its prison as Hikari looked longingly. Her control over reasoning slowly diminishing to almost none existence. This isn't the first time, Hikari have seen her brother's cock. After all, for the past month she'd slowly built up to this point. It started with just watching her brother, while he's asleep. At some point (exactly when Hikari doesn't know,) this went from just watching to touching to…this.

"Now, grab a hold of our dear Onii-chan's cock."

Grabbing Taichi's cock in her hand, Hikari was amazed at how hot it felt in her hand. She heard her brother moan slightly. The moaning caught her off guard that instinctively, she froze. As sweat started to appear on her forehead, Hikari slowly looked up towards her brother's face. Her brother's still, calm, sleeping face. Knowing that her brother wasn't awake, caused a slight relief for Hikari as she returned her attention to the important matter at hand.

Taichi's cock continued to pulsate in her hands.

"Come on now. Don't keep him waiting now. Move your hand, slowly."

Hikari slowly started to pumped her brother's cock as she breathed heavily. Part of her is telling her that she needs to stop. But the other part of her is winning. Her lust for her brother.

"Onii-chan's cock. It's more alive than usual." Hikari looked up towards her brother's face. "I wonder what short of dream he's having?"

Hikari continued her slow assault. Which did nothing but fuel her own arousal that was building up inside of her. Is this what Taichi was currently feeling? Hikari could feel something wet and slightly sticky on her hand, as she continued her handjob.

"Yes. That's it. Take in his scent and taste him."

With labored breathing, Hikari cradled her brother's cock with her hands. With a deep breath, Hikari inhaled her brother's scent. Taichi smelled slightly sweaty and grassy. Like he'd just finished a soccer game. It was intoxicating for her. As she stuck out her tongue, she slowly licked her brother's cock from the base, all the way to the tip. Taichi's cock slightly throbbing in her hands as she continued her slow assault. His light sticky substance started to leak out of the tip of Taichi's shaft even more. And as Hikari continued to lick her brother's shaft, she twirled her tongue around the tip, as she tasted him. Licking some of Taichi's precum into her mouth, Hikair tasted her brother.

At the same time, Hikari's own arousal grew wetter and hotter. A burning fire was roaring in between her legs. A fire begging to be quenched. As Hikari continued her assault on her brother's cock, she started rubbing her wet folds under her bottom clothing. Her own mind becoming lost in the haze of her lust.

"This all good and all, but let's go a step further. Suck his cock."

Hikari stopped licking her brother's cock. For a few moments she stared at it with a longing look. Her eyes screaming with lust as she breathed heavily. Her mouth started salivating at the meager thought of giving Taichi an oral. Her body drowning in pleasure.

"I shouldn't. I've already gone farther than I have before. Plus, what if Onii-chan wakes up? I-"

"Stop with the excuses. Lower your head and let lust guide you."

"'Let my lust guide me?'"

Unable to resist anymore, Hikari gave into her lust. Putting her brother's cock in her mouth, Hikari started to suck on it. All the while, continuing rubbing her wet pussy underneath her soaked pajama bottoms. Slowly, Hikari lowered her head as she used her tongue to lube her brother's cock. Then, once she got Taichi's cock as deep as she can inside her mouth, Hikari started to raise her head. All the while, sucking and slurping on her brother's shaft.

"Good. Very good. Don't use your teeth. Keep the lips tight and speed up your movements. Just enough to add more pleasure, but not to make him cum. After all, let's enjoy this a bit longer."

Hikari followed the instructions and started to increase her movement. At the same time, trying to be aware of the position of her mouth. After all, she doesn't want to wake up her brother. Not like this. However, Hikari could feel her own orgasm getting closer and closer as she continued to rub her wet folds intensely.

"This is bad." Hikari thought as she bobs her head up and down. "At this rate, I'm going to cum. And despite the fact that Onii-chan is still asleep, he still hasn't ejaculate yet. But what if he woke up and sees me doing this?"

The thought of Taichi waking up and catching her sucking him off, was enough to send Hikari over the edge. She released her brother's cock from her mouth as her back arches with pleasure. Her orgasm hitting her hard as she stared at the ceiling with a forced silent scream. As her orgasm slowly recedes, she gave a couple of deep, silent breaths. She could feel the wet spot on her clothing growing bigger. But that's the least of her worries.

Hikari looked down at her brother's throbbing cock. It aches for some hot release. Despite cumming already, Hikari gently grabs Taichi's cock. She was determined to continued where she left off. Her eyes full of lust and the desire to make her brother cum from his little sister's forbidden mouth was too tempting to pass over tonight.

"Not when I've already gone this far."

Without any more hesitation, Hikari placed her mouth back on Taichi's cock. This listed a moan out of Taichi's mouth. This caused Hikari eyes to turn toward her brother, yet she refused to slow down. Seeing that Tachi was still asleep, caused some short of relief for Hikari. She continued to suck and lick profusely on Taichi's cock.

"How would this feel, if Onii-chan would penetrate me?"

Thoughts flew through Hikari's mind, as she imagined Taichi was the one who'd take her virginity. As he whispered in her ear that he loves her. All the while pounding her mercilessly for some sweet release. Her fantasy came to an end, as eventually, Taichi moaned in his sleep. His hips instinctively thrust up. Placing his cock deeper into Hikari's mouth as he orgasmed. Hikari made a soft noise as the back of her throat got coated by her brother's cum. Not wanting to make a mess, Hikari swallowed her brother's seed as she hungry took it. A few moments went by before Taichi's cock went limp, as the last drop of his seed entered his sister's mouth. Hikari released her brother's cock from her mouth.

As her high wore down, guilt struck Hikair like a lightning. Shocked at her behavior, Hikari quickly and as silently she could, got off her brother's bed. She then proceeded to leave hastily from Taichi's room. Hikari retreated into her own room. As she closed her door fear overcame her.

"OH GOD! WHAT HAVE I DONE?!"

Hikari placed her hands on the side of her head as she slid down onto the floor. Her back leaned against her door as much as possible. Tears dropped onto the floor in between her soiled pajama bottoms. As the event of what just transpired went through her mind. Her heart ached as it pounded in her chest. Fearful of the wrath her brother would say and do to her if he found out what she just did. For there was no way that Taichi wouldn't wake up, and not know that it was her.

"Why did I do that?! What made me do that?! What was I thinking?!"

"You were wanting to sleep peacefully." The voice whispered.

Hikari could feel a light, gentle breeze blowing pass her left ear. Like someone or something was blowing on her ear. The sound of the fan running hummed in the background.

"Now you can. You're feeling exhausted, now aren't you?"

Tears kept flowing down Hikari's face as she stared mindlessly at the ground. The voice was right. She was exhausted, despite her heart thumping loudly in her chest. But the feeling of despair just wrapped itself around her like a blanket.

"But this isn't right. What I just did was wrong. Taichi would hate me for what I did. The person that I love the most would hate me. I shouldn't have done it."

"But this is just like what you've been doing for the past week wasn't it?"

Hikari's thought process stopped in its tracks. As events from the past week came rushing through her mind.

"That's right. You remember the feeling of caressing his body with your soft, delicate hands. How you felt when you fondled your breast and massaged your aching pussy. All in hopes that it was Taichi who was doing those things instead. But most importantly you wished that he could come INSIDE you."

"But Taichi would never do something like that."

"Not unless you do something about it. After all you need to do is to keep him asleep. Give him something so he won't wake up. That way you can have your way with him."

Hikari couldn't believe what was transpiring. She couldn't possibly be considering in drugging her brother. Could she?

Hikari tear stained eyes turned towards her bed. Sleep was beckoning her. Slowly, she got up from off the floor and staggered to her bed.

"That's right. Sleep. Sleep peacefully tonight. And just consider what was just said."

Hikari didn't replied as her body laid on the bed, wrapped tight in her blanket. As sleep was threatening to consume her, surrounded by despair. One last thought went through her mind as she closed her eyes.

"I am FUCKED up."
