Chapter Four

-o-

Arguing wasn't the only reason Daisuke avoided his sister.

He'd long since known that her energy was too much for him, and sometimes the intensity of it caused him so much stress, he literally felt sick. Ever since he was a child there had been times when he had to hide in the closet in his room to avoid her when she was particularly uptight, as though his instincts were telling him that she was dangerous. That was probably why he had always felt a little sorry for Yamato, who had been the focus of her attention for many years.

Having Jun back from college for the weekend was not just stressful, it was painful. She was extremely energetic, talking about everything she did at college, her friends, roommate, teachers, and classes, regardless of the fact that he didn't want to know any of it. She would drag him around the house with her, pointing out random things that needed to be cleaner, and scold him for not doing a good job with his chores. Then she'd lecture him for hours until he finally agreed to go shopping with her.

Thanks to that, Daisuke found himself returning home in the afternoon with Jun, after an entire Saturday of carrying her shopping bags. He literally wanted to break her face.

"This was so much fun!" Jun said cheerfully, bursting into their home with a bright grin on her face. "It's so nice to have a brother, especially one who is strong enough to carry all my bags." She turned, patting his shoulders proudly. "Daisuke, good job on getting strong. You're much more manly now, even if you are still a little short."

He glared at her, tossing her shopping bags to the ground. "I'm going to my room," he complained, kicking off his shoes and stomping through the house tiredly. When he reached his room, he fell onto his bed face down, content to just lay there until his exhaustion died down. Having a sister like Jun is torture!

In the other room, he heard her happily going through her bags, sorting out her spoils and putting them away. She was talking on the phone with one of her friends, explaining in great deal every single store she'd gone to. It made his ears feel like bleeding. Why couldn't she be quiet?

Later, it did get quiet. She got off the phone, and continued to do things in her room in silence, leaving Daisuke to drift toward a half-asleep kind of nap.

But it didn't last.

His hair stood on end on his neck, and a strange shiver went down his spine. It was the feeling of being stared at, and he opened his eyes with a strange feeling of fear. The desire to hide in his closet like he'd done as a kid came back to him, and he slowly sat up from his bed to look at his open bedroom door.

Jun stood in the doorway, staring at him blankly.

"What is it now?" he asked, scowling at her. "I'm done going shopping. In fact, I'm never going shopping with you again!"

She ignored his statement, instead walking into his room, and slowly pulling the door closed. The corners of her mouth began to turn up in a smile. "Hey Daisuke," she said.

He wasn't sure why, but her tone made him uncomfortable. "What?" he demanded. He wanted to tell her to get out, but something was stopping him. Like his body would not listen to his mind.

"You've grown up some since I've been at college, haven't you?" She grinned, walking toward his bed and sitting down beside him. He scooted away warily. "Did Mom and Dad give you the talk yet?"

His eyes widened, and he turned away from her with his face beet red. "Jeez, Jun!" he groaned. "Why are you even bringing something like that up? You're so annoying!" He thought about what she was implying, about their family being half demon, and let out a sigh.

That's right. She had almost been taken away to be impregnated by a full fledged demon, hadn't she? Was she… even okay? Maybe he shouldn't bring that up...

"It's… kind of a lot to digest," he admitted after a second. "Isn't it?"

She laughed, patting his shoulder reassuringly. "Don't be so down about it, Dai. It doesn't make us evil or anything," she giggled, watching him blush with great amusement. After a moment though, she seemed to grow serious. Her eyes stared at the far wall, as though she was contemplating something very carefully. "But… yeah, you have a point. It's actually pretty hard, you know? Being the way we are. Sometimes it can be so unbearable…"

The heat in his cheeks was only getting worse. He knew what she was talking about, the dreams, the sex drive, the frustration. Talking about it was kind of a relief, but at the same time, this was his sister. It was almost more awkward than talking about it with his parents.

"The worst part is not just feeling horny all the time, either," she huffed. It astounded him how easily she could talk about it. "The worst part is that, no matter who you do it with, they just can't last as long as you need them to. So you always end up being the one still unsatisfied at the end."

"Jun, stop it," Daisuke snapped. He glared at her, his eyes flashing dangerously. He didn't know why, but her words were making him feel afraid. I don't want to hear this. Not from you, not from anyone.

She just looked at him. Her eyes captivated him, and her gaze was so magnetic, he felt like he was frozen in place, unable to look away. There was a deep, powerful hunger that seemed to swirl in the depths of her pupils, drawing him in.

He swallowed, but his throat felt dry. That closet was really beginning to seem appealing right now.

[scene start]

"Hey Daisuke," she whispered, her face inching nearer so gradually, he didn't notice it until their lips were so close he could feel her breath on his mouth. "You feel like this too, right? What do you say? Want to try it?"

Daisuke felt his entire body shudder from head to toe. He managed to find his voice. "You're my sister," he whispered back, pulling away from her. "What are you saying?"

"It's okay," she smiled. "I know what I'm doing. Besides, you're the one at fault for tempting me like this. Aren't you the one suffering the most?"

He chewed on his lip, aware that his heart was racing in his chest. Suffering, he thought with a grimace. Yeah… kind of. "It's too weird," he said. "It's not right."

"It's okay," she said again. Suddenly, she was leaning over him, pressing his body into his bed with her hands. Her breath shuddered unevenly with desire. "I've been in this situation before, remember? You're not as alone as you feel. I know what it's like. I'll make you feel good… promise."

She kissed him.

His own sister, kissing him.

At once, Daisuke felt a rush of emotions, ranging from horror and revulsion, to acute desire. Even as his mind rejected what was happening, his body became so hot that he could barely think. Her lips were soft, and they tasted sweet. Her tongue in his mouth made him forget what he was thinking, and he found himself locking tongues in a battle for dominance. When her hands unbuttoned his shirt and pushed it open, he followed her lead and moved his hands to the edges of her blouse, beginning to pull it upward.

Then he paused. What am I doing? He thought blankly. Am I really about to… with Jun… do… he cringed suddenly when her hand gripped his erect member through his pants.

"I can help you with this," she hummed, smirking at him. Her expression was hungry, like a lion about to devour its prey. "Don't worry, Mom and Dad are on a trip until Monday night. It's just you and me, all alone." She knelt down, crushing his lips with hers for several minutes. Then she moved her head, whispering directly into his ear. "Let's see how long we can go."

He tried, really tried, to push her away. So why was he holding her so tightly? How did their clothes end up on the floor? Why couldn't he find the will to stop? It's not right, he thought desperately, panting with need as her mouth explored his chest. She seemed fixated by his neck and collarbones, and kept going back to bite him and kiss him there. This isn't right. It's wrong. So why… why don't I want to stop?

Jun's skin was like hot velvet. His fingers ran over every part of her, almost in amazement, as though he couldn't get enough. She hissed in satisfaction when he pinched her nipples, and whispered dirty things in his ear with such a husky voice, it alone made him incredibly aroused. "I see stars when you twist them," she whispered, speaking about her nipples. "Yes, touch me right there…. Mmmm…. Feels good…"

Her hands groped his body deftly, as though she too was fascinated by his skin. She kept running her fingers along the muscles in his chest and stomach, smiling in satisfaction at how much he had grown. With one hand, she stroked and toyed with his dick until it began to drive him crazy.

It was too late for him to stop himself now.

Forcefully, he twisted their bodies until he was on top, pushing her down into the mattress. She laughed, grinning up at him with eyes sparkling, and her skin glistened with sweat and desire. "I'll teach you what feels good," she hummed. Her hands reached out for him, drawing him close.

Without the strength to resist her, he leaned in and kissed her with his eyes closed. His hands found their way to her legs, pulling them apart, and he positioned himself over her eagerly.

"Wait," she whispered, stopping him with one hand against his bare chest. "You're not just going to stick it in me without making me feel good first, are you?" She chuckled, taking hold of his face and pushing his head down toward her groin. "Lick me, first."

Daisuke's eyes snapped open. He found himself staring at her vagina, overcome first with hesitation, and then acute desire. But he wasn't even sure how to do that. L-lick her? He thought, shuddering. Isn't that… weird?

"It's okay," she said. Her fingers stroked his head, running through his hair in a gentle, massaging way. It felt good. "It's easy, trust me. You'll probably like it."

He swallowed, surprised that his mouth was already damp with moisture, as though anticipating what he was about to do. He only hesitated a moment more before throwing caution aside. Just like that, he was licking her.

It was weird.

Her skin was velvet soft, and moist with her juices, as well as his saliva. The folds in her skin were strange, and it was hard to figure out where exactly he was supposed to lick. Was it this small, hot, nub of skin that had become almost rock hard from the stimulation? Or was it the hot, wet opening between her legs? The more turned on she became, the sweeter her juices seemed to taste.

It was uncomfortable, and embarrassing. So why did it make him so hard?

"Don't stop!" she moaned, the muscles around her legs and pelvis beginning to tremble. Her fingers gripped his hair tightly, and her back arched on the bed. "Ah! Ahn….Nnn… yes…. R-right there…" she panted, growing hotter and hotter, her muscles twitching more and more, until suddenly she gasped and dug her fingers into his head, arching her back and squirting juices into his mouth.

The orgasm was a shock to him, and he pulled away from her with a stunned expression, wiping his mouth. He stared down at his older sister, watching her squirm for almost a minute, with a mixed sense of guilt and excitement. His dick was hard, and aching.

Daisuke watched as she calmed down, and noticed that her body had not relaxed at all. It was like she still needed more. "Pretty good," she giggled, "for a first time. Now… it's your turn." She sat up, grasping his shaft with her hands, and pulled him toward her. He choked on his breath, surprised, and could not resist when she flipped him over and pinned him down. He couldn't say a word before her mouth was suddenly on his pulsing hot member.

With her tongue, she circled the tip expertly, watching his face to see if he liked it. He seemed too stunned to do much besides lie on the bed, panting, with his eyes wide open, so she kept experimenting. She tried licking him, pumping his shaft with her hand, and fully engulfing it in her mouth, noticing all the ways that he reacted. After several minutes, she pulled away, grinning at him.

"W-what?" he asked, feeling embarrassed. Why was she looking at him like that?

"It's just interesting," she smirked. "Everyone reacts differently with oral sex, and something that feels good to one person may do nothing on someone else." She ran her tongue from the base of his balls all the way to his tip, smacking her lips in satisfaction at his expression. "You don't seem to care what I do, any kind of touch seems to make you just as excited."

He cringed, looking away in frustration. He probably would have replied, but she effectively rendered him unable to speak by placing her mouth over his penis once more. Sucking on him and pumping her head down rapidly, she took him in deeply until his balls were touching her mouth, over and over. Daisuke's eyes closed involuntarily. I can feel myself going into her throat! He thought, dimly aware that his back was arching as he drew closer to his climax. Shit, it feels…so good…

Just when he was about to come, she pulled back, taking him out of her mouth and grasping him with her hands. She continued pumping him with both hands, occasionally licking his tip, until finally he reached his peak. His climax hit him like a digital attack, or at least that was how his brain tried to comprehend it. It was different than his experience when he'd been drugged and banged. Then, it was all a blur that he couldn't control. Now, he was acutely aware of it, and it seemed to last half a minute before his body stopped quivering.

But even after that, he continued to feel unsatisfied. It wasn't enough.

"Yeah," Jun said softly, touching his dick with her finger and watching as it only stayed soft for a moment, before beginning to stiffen up again. "You're just like me."

He panted, trying to catch his breath, and stared up at her with a distressed expression. Both of them had orgasmed. But neither of them were remotely satisfied.

"Okay," she said, stretching out over him and leaning down to breathe into his face. Her eyes grew black with desire. "I'll teach you something new, now."

Daisuke swallowed back his fear, inwardly throwing aside his inhibitions. He was done trying to resist any more.

-o-

"Harder! Ahn! Yes…. F-faster!" Jun grunted, squirming more and more as he pounded into her. He tried to respond to her words, but he wasn't even sure he could go any harder. Wasn't he already slamming into her with everything he had? "Ah-AH! Mmmm…. Y-yes, l-like that…. Ahhhhh…."

He gritted his teeth, growing harder at the strange sounds that came out of her mouth. It seemed like forever before finally, she cried out with a strangled gasp, and her walls tightened around him with shudders and vibrations so powerful, it brought him to his own orgasm. They clutched to each other, oblivious to anything but the pleasure, until it began to die down.

How long has it been? Daisuke thought, pulling out of Jun and rolling over to lie beside her. They had been doing it for so many hours, he didn't know if it was night or day. His body was exhausted, and all he wanted to do was sleep, but still they kept going. Just as soon as he would finish climaxing, and would start to think, maybe now I'm done, then he would be staring down—or up, in some cases—into Jun's eyes. He would see the lust still strong in them, and his own body would respond in kind. It was a never ending cycle he couldn't seem to turn off.

"I-I'm almost finished," Jun said. Lying on her back with her arms outstretched, she panted heavily. Her skin was red, covered in sweat and the evidence of sex, and her entire body trembled with flashes of pleasure and exhaustion. She giggled, as though she couldn't stop herself. "N-never… never done it… this many times before. Such a relief…" her laughter died down, and she forced herself to sit up. "Hey," she said, smiling a wide, almost dopey grin. "You're not done yet, are you?"

Daisuke looked up at her helplessly. No, he thought. Not even close. I keep feeling like something is missing. Like no matter how much we do it, it's never going to be enough. It's almost like, because it's Jun, my body is constantly stressed by guilt and tension. I'll never feel release at this rate.

"Ah, I guess not," she giggled again. Her hand went down to his dick, touching it sympathetically. "I think you're worse off than I am."

"Jun," he groaned, wincing at the sharp stab of tension her touch caused him. "I think we should stop. This isn't a good idea."

"It's a terrible idea. It was from the very beginning."

"Then why are we doing this?"

Her expression shifted, becoming one of pain and wistfulness. "Because," she whispered helplessly. "You're the only one who understands what it's like. Did you know it's already 4:00 AM? That's over twelve hours since we started. Everyone else in the world would think we're crazy, and could never last that long. But…" Absently, she began to stroke him again, paying careful attention to the areas he was most sensitive, until he was just as hard as he'd been the first time they'd done it. "But we're not crazy. We're cursed."

Yeah. Cursed with demonic blood and supernatural sex powers. If it wasn't so miserable, maybe it would have been fun. Instead, it had gotten his and his friend's souls claimed, gotten them gang raped, and now here he was fornicating with his own damn sister.

If that wasn't a curse, then nothing was.

"D-dad says… falling in love is the cure," Daisuke said, looking for anything that might bring them a sliver of hope. He winced as her skilled ministrations brought his hard on right back. She really was good at this.

"I am in love. But he doesn't love me back." Jun grimaced, and suddenly she began to grip him tighter. Her movements became rough, almost painful, and he gasped and jerked in surprise. "Shame on you, for making me think about unrequited love while I'm trying to forget!" she hissed. Just when he was about to cum, she gripped him hard, causing him to cry out, and kept him from climaxing. "Don't move," she said darkly.

Suddenly she got up, leaving his room to go rummage through hers.

In a daze, Daisuke lay panting on his bed, trying to figure out what was wrong with him. There was a sinking feeling of dread coming over him when he realized… out of everything they'd done, all the positions they'd twisted their bodies into, and all the times they brought each other to a climax, nothing had felt as powerful as what she had just done to him before she left the room.

So what did that mean?

Am I…? He shuddered, staring down at his naked body with shock. Am I turned on by… pain?

Jun came back into the room holding something for him to see, and smirked when she caught sight of his almost terrified expression. "Do you know what this is?" she asked coyly.

Daisuke stared at it, not sure whether to feel sick, or to be angry. What was she going to do with that?

"It's a strap on," she replied. "A special one, in fact. See this part? This is the part that slips into me. It's designed to hit my G-spot from both the inside and the outside, as long as I have it strapped on. She knelt on the bed in front of him, slowly slipping that part into her, and maneuvering it into place. Then she connected the straps around her waist, and under her legs. When she was finished, it was clasped tightly around her. "And this part," she jiggled her hips, making the large, silicone protrusion sway in front of him, "is the part I'm going to stick in you."

He was now frighteningly aware that he was hyperventilating. "No wait, that's weird!" he complained, sitting up and trying to get off the bed. Jun grabbed him and shoved him down onto his back, and proceeded to kiss him and grope him until he was panting from arousal more than fear. "S-stop!" he pleaded, hating his brain for slipping into a fog. Why was she doing this to him?

"Trust me," she whispered into his ear, knowing that it made him weak. "Guys almost have it better than girls. Did you know, anal sex for guys is supposedly the most pleasurable sexual experience we know about? Not that I would know, I'm not a guy. But if it's true, it almost isn't fair."

"Jun…" he whimpered, squeezing his eyes closed and cringing as he felt her hand stroking his throbbing shaft. He was getting weaker.

"It's okay, I know how to find your prostate. You've made me feel really good today, and I think I've just about hit my limit. You're the one who isn't satisfied yet, so it's my turn to make you feel good." Kissing him, stroking him, rubbing her breasts against his chest, she used everything she had to make him succumb, so that when she pressed his legs open and touched the strap on to his hole, the only thing he could do was gasp.

It slid into him slowly. She had coated it with slimy lube, the kind that tingled with a strange minty sort of feeling. All he could do was grip tightly to her body, choking on every breath, until it was plunged deep inside him. There was no preparation. No sticking her fingers in first to get him warmed up to the idea. She just forced it in, whispering into his ear with her husky voice, "it's okay, Dai. You're an incubus, your skin stretches really well. This will be easy, you'll see."

But that didn't mean it didn't hurt. So weird! He thought, shuddering. It feels… so full… so...

And then she began to move. Three thrusts in, she found his sweet spot, and with a twisted grin, she pounded into him roughly, always making sure to hit it. Each time, she let out her own moan, as the part of the strap on that was stuck inside her would pound against her G-spot with every thrust. And with careful attention, her hand wrapped around his shaft and pumped it up and down.

Now he was beginning to see stars. Everything that he'd felt up to this moment had only been the start. This was where his real climax was starting to build.

They clung to each other, gasping and moaning, each bucking their hips and kissing any part of skin their mouths could reach, until they climaxed. First it was Jun. She cried out in a loud, erotic voice, her hips convulsing in a powerful orgasm. The motions jarred him on the inside so strangely, it pushed him over the edge too, and he came violently against both of their stomachs.

It was probably several minutes later, that he realized she was pulling out of him. Staring wide-eyed at the ceiling and panting like a fish out of water, he listened as she removed her strap on and dropped it unceremoniously to the floor.

Moments later, she lay down beside him, curling up against him with her arm draped over his chest. "Dai," she panted, nestling closer and kissing his cheek. For some reason, even after everything they had just done, it made him blush. "Thank you."

He shuddered, wishing that he knew how to respond. Right now, he just felt exhausted. Not quite satisfied, but definitely better than he'd felt in a long time. It won't last, he thought with a grimace. Soon, it'll catch up to me. Everything I just did with my own sister. And then I'm going to wish I was dead.

"You know," she whispered faintly, already slipping into unconsciousness. "I think you might be a bottom bitch. That orgasm was much stronger than all the others."

"J-just go to sleep," Daisuke blushed. He closed his eyes, afraid that she was going to say something else, but then realized she was already out. That left him alone with his thoughts, and his naked, sexed up sister asleep in his arms.

This really was the worst.

TL;DR

Jun sexually coerced Daisuke into intercourse, taught him a few things, and they figured out that Daisuke seems to like it when he takes it up the ass. Other little tidbits of info, Jun is frustrated by unrequited love and believes their demon blood is a curse.

Three loud knocks startled Takeru from reading his book, but before he could even get off the couch he heard Daisuke yelling from the other side.

"TAKERU PLEASE OPEN UP!"

Takeru winced, pulled his front door open, and stared at Daisuke unhappily. His friend was standing there with his face red and his eyes downcast as though he couldn't even look Takeru in the face. "I opened it as fast as I could," he complained. "Why are you yelling at me?"

"Please let me stay here tonight, I'm begging you!" Daisuke blurted, his arms clenched and trembling by his sides.

His initial annoyance dying down, Takeru studied him with growing alarm. What was wrong? Why would he ask that so desperately? It wasn't like he'd say no. Well, maybe I would, but under normal circumstances I wouldn't. "What's wrong?" he demanded, pulling the door open further to allow his friend inside. "Did something happen?"

Daisuke's face twisted into a strange expression he couldn't decipher. "I just need to get out of the house," he mumbled, walking inside and making his way to the living room. "My... family... is too much for me to handle right now."

I think it's probably best if I don't ask, Takeru thought, closing his door with a sigh and following Daisuke into the living room. It was already the late afternoon on Sunday, and he'd finished all his homework, so he didn't mind the company. Although maybe I should invite Hikari over again? No wait… maybe I'll have Daisuke and I go out and visit the others. That might be safer…

Daisuke threw himself on the couch, curling up on the cushions with his back facing outward, as though he didn't want to look at anyone or anything. His back was rigid with tension, and his sexual frustration seemed just as strong as ever, if not more so. "Thanks," he mumbled unhappily. "You're a life saver."

Takeru came into the room as well, taking a seat across from the couch. "Your family, huh?" he asked dryly. "So it's all confirmed then? You're a demon?"

Daisuke's body stiffened for a second, as though he had forgotten how to breathe. He relaxed a moment later, turning over to face Takeru reluctantly. "Half demon," he whispered. "And… yeah."

"I thought as much," Takeru sighed. He didn't mention his conversation with Yamato, but he was thinking about it. Wondering if Daisuke, if Jun, were the type to end up stealing souls after all. Stop it Takeru, he's your best friend. He's an idiot sometimes, but he would never do that, you know that.

As the silence between them continued, Daisuke rolled onto his back and draped an arm over his eyes. He looked utterly exhausted, and all of his muscles seemed tense. More than that, the sexual frustration that lingered under his skin was so potent, Takeru felt like his senses were smothered in it. "Hey Takeru," he mumbled tiredly, "I don't know if I feel up to talking about… the whole incubus thing… right now. Is it ok if I take a nap?"

Takeru shivered, resisting the pull of his magnetism. I probably need to stay away from him anyway. "Yeah of course," he said quickly. He stood up and walked to his room, closing the door after he entered. Only then, did he realize that his whole body was sweating and tense. Shit, it's like my body is reacting sooner than usual now. Why am I so turned on when I see him? What am I supposed to do?

He sank to the ground, his back against the door. Groaning, he held his face in his hands. The biggest problem was that, Daisuke being like this made him stressed to the point he almost felt sick. He was acutely aware of him, his moods and his expressions. Seeing him so down made Takeru want to do everything in his power to see him smiling again. To see him find relief, if only for his own sake.

He's all I think about, Takeru thought. I'm so aware of him, my skin feels like it's buzzing when he is close. I just can't stand seeing him like this, but what can I do for him? He gritted his teeth. I'm doing the only thing I can; letting him come over when he needs to. Believing in him. Being there for him as best I can. What more can I do?

Takeru paused, a thought jolting him suddenly. Thinking like this… did that mean… that he… liked him?

His heart began to race, and swallowing with a swell of nervousness, he pulled out his phone and dialed Hikari's number. She picked up on the second ring. "Hey Hikari," he said, hating the way his voice trembled. "How do you know if… you… like somebody?"

Hikari was quiet on the other end for a brief moment, as though she was holding her breath, and then she sighed loudly. "Daisuke is over," she said. She didn't even have to ask. "Takeru, don't do anything till I get there, okay? There's something we need to talk about."

Takeru nodded, then realized she couldn't see him. "Okay," he mumbled miserably.

She hung up, leaving him feeling lost in his thoughts.

Thanks for getting this far, I apologize for the uncomfortable incest scene. Don't worry, it's the one and only time it will occur, and it's mostly there to set up some things for the future. Thanks for sticking with me, and I hope the warning and tl;dr helped!

As always, I am ever in need of constructive criticism, I have many areas to improve. And I look forward to hearing what you think! See you next time.
