Chapter 0 - Movie Night

Taichi had thought that giving his sister a key to his apartment would be a convenient thing to do, and indeed it had been. He had grown used to coming back from work to find Hikari hanging out at his place, cooking or reading or sometimes playing his video games. It was a good place for her to hang around, especially since, unlike Taichi, she still lived with their parents.

When he came home after a particularly rough day on the job, however, he opened the door to find her sitting on the couch, waiting for him, with a stack of magazines and DVDs on the coffee table. A very particular stack, as it turned out, one that Taichi could recognize from a mile away.

"H-Hikari," he said, attempting to sound casual. "What brings you here today?"

"What do you think, nii-san?" Hikari replied, looking him dead in the eye. "I found your porn stash."

"...Yeah," said Taichi. "I can see that."

"I was doing some cleaning, since you always leave this place an absolute mess, when I stumbled upon this lurking under your bed." She picked up a magazine from the top of the pile, examining it. "And then I discovered that nearly all of it is siscon stuff..."

Taichi paled and froze. There was no talking his way out of this one. "Well, uh, Hikari... you see..."

"I'm going to stop you right there," said Hikari, picking up a DVD case promising hot step-sibling action, and walked towards him until the two were only a few inches apart. "Don't worry, I'm not going to tell anyone about this-"

"Oh, thank god," said Taichi, able to breathe again.

"-on one condition," his little sister continued.

Taichi gulped. "And that is? Whatever it is, I'll do it."

"Watch this with me," said Hikari, a devilish smirk on her face as she held up the DVD case.

"I, um, what?" said Taichi, completely lost.

"The two of us are going to sit down on your couch, pop in this disc, and watch the whole thing. Or do you want mom and dad to hear what kind of porn their Taichi is into?"

"I-I don't... I don't understand," said Taichi, his eyes darting around, trying not to look at his little sister and the DVD she was holding.

"Let's just say that I want to understand what about this stuff... excites you so much," said Hikari, wetting her lips.

Taichi sighed, then slumped. He had no way out of it. It seemed obvious that his sister wanted to mess with him, and he had no choice but to go along with it. "Okay," he said.

"Great!" said Hikari, suddenly very cheerful. She got on her toes and gave Taichi a peck on the cheek, which he continued to feel long after it ended.

Deeply confused, but heart throbbing, Taichi took the offered DVD and put it into the player hooked up to his TV while Hikari sat down on the couch, resting her feet on the coffee table.

Taichi pressed 'play,' and the movie started up. He made his way to the couch as well, trying not to notice that his sister was still dressed in her high school senior uniform, including bright white socks that stretched up to her knees. 

Dammit, the whole point of all this porn was catharsis, so that he wouldn't have those kinds of thoughts about Hikari anymore. But it had backfired spectacularly, and he had to go along with it.

He sat down, and the intro credits faded out as the movie began to play.

As the obligatory interview portion began, Taichi realized that the woman in the DVD Hikari had picked looked quite a bit like she did. This was getting worse by the moment, and then Hikari continued the trend.

"Hey," she said, pointing at the screen and leaning towards Taichi. "That girl looks a lot like me, doesn't she?"

"I, uh... I guess so," said Taichi, blushing. He wasn't about to admit that this was one of his most-revisited videos.

Hikari continued to lean in, closer and closer, until her head was on Taichi's shoulder. Then she scooted in, pressing her side against Taichi's. Taichi gulped, trying to suppress the flood of emotions threatening to burst out.

Hikari treated this like she did every movie she watched with her brother, which was to say that she provided a running stream of snarky commentary. Taichi was thankful for that at least, because if he was listening to her comments he wasn't actively watching the cameraman playing the role of the brother begin to strip off Hikari's... the on-screen woman's clothes.

"Hm, not quite as much like me with the school uniform off," said Hikari. "But still pretty close. Say, nii-san, who do you think has better tits? Her or me?" She proceeded to turn in her seat, taking hold of his far shoulder and pressing her uniform-covered breasts against Taichi's side.

"Um, I don't really think-"

"That it's a fair comparison? It's true, you haven't seen mine since they started to grow... I could always take my top off and let you compare for yourself." Kari licked her lips, an evil glint in her eye. "Oh look, they've gotten to the blowjob scene. Looks like she's doing pretty well, but I bet I could do better. See? She's just licking it in one spot like a lollipop. My friends at school say that you've got to move around a lot more. Is that true?"

Taichi, in a flash of realization, understood what his sister was trying to do. He pushed her away, realizing that she had placed her hand on his thigh.

"Listen, Hikari. We... we can't be doing this. We're siblings."

"So are most of the characters in your porn, but that doesn't seem to be a problem for you. Listen," she said, leaning back towards him and placing her hand on his chest. "You know you want this. And I want it too. You have hangups, I get it, but we're both adults. This is a choice we can make for ourselves."

Taichi gulped. "I... but..."

"How about this," Hikari said, running her fingertips down his chest slowly. "I'm going to kiss you now. You can stop me if you want to, but I bet you won't."

And with that, she bent her head towards Taichi, meeting his lips with hers.

And Taichi didn't stop her.

His lips were stiff and dry, especially compared to the softness and wetness of hers, but as she pressed forward with the kiss, rearranging herself so that she was sitting on his lap facing him, he slowly melted into it.

And the worst part? It felt good. Natural, even. His little sister's lips were warm, and welcoming, and fit nicely with his own. He found himself reciprocating, and one hand steadied him as if to anchor him to reality while the other one began to stroke Hikari's short brown hair.

It felt so natural that he didn't even notice the transition to Kari using her tongue, nor him his own. All he knew was that they were well and truly making out, brother and sister, just like the characters on the TV.

Hikari broke off the kiss abruptly and, smirking, licked her lips. "See?" she said. "I told you you wanted this.

Taichi blushed and stammered, neither of which were actions he was accustomed to, and he began to speak. "I- I don't-"

"Don't try to deny it, you big perv," she said, sticking her tongue out at him. "Not with your hand on my ass like that."

...Wait, when had that gotten there? Taichi's hand shot back and he blushed even harder, trying to reconcile the conflicting emotions in his mind.

"Listen," she said. "I'm going to take my clothes off now. I want you to watch your little sister strip for you."

Taichi's mouth and throat were bone-dry all of a sudden. Unable to do anything else, he nodded.

"Good," she said, giving him another quick kiss.

Hikari proceeded to stand up, revealing a wet spot on Taichi's pants leg where she had been straddling him. She took a step away from the couch, turned, and began undoing her uniform ribbon, her arms stretching back and pushing her chest forward. She undid the ribbon and then tossed it aside, her hands moving along her body.

She lifted up her skirt, just enough to give Taichi a glimpse of her upper thigh, and then dropped it again. She undid the top buttons of her shirt, each time revealing more and more smooth, lovely skin.

She worked her way down until the shirt was completely unbuttoned, and she opened it to reveal a lace-edged bra. She slipped the shirt off her shoulders and then cupped her breasts with her hand, pushing them up and making them jiggle.

Hikari then turned around and slid her hands along her skirt-covered butt. Then she unzipped the skirt and let it fall to the floor, then stepped out of it and bent over in front of Taichi, accentuating her ass and showing a hint of the dark, wet spot between her legs.

Taichi was, naturally, hard as hell by this point. No matter his moral objections, a woman that he loved and, yes, lusted after was stripping for him. His pants were tented, and there was no hiding it.

Hikari wiggled her butt, audibly giggling a little bit as she did so, then turned around to see Taichi's biological reaction to her display. She grinned widely and knelt in front of him, pushing his legs apart to get between them.

"That looks uncomfortable, nii-san," she said with a giggle, and proceeded to fumble with his belt.

Taichi did not stop her. He wasn't sure he was capable of moving at this point. She got his belt undone, then his pants button, then pulled down his zipper, revealing his basic red boxers.

She began to tug at his pants and, to Taichi's own surprise, he helped her wriggle them off of him. The boxers were next to go, and up sprang his very-erect cock, Hikari's eyes widening in pleasure as she examined it. She bent her head forward and stuck her tongue out, dragging along the underside with the tip of her tongue. Taichi's muscles locked up, and a bead of precum appeared at the tip of his dick, a bead that Hikari lapped up greedily. Then she stood up, grabbing Taichi's hands with her own.

She guided his hands from their resting place - clenched around the knees of his pants, and brought them to her hips. Her skin was soft, and warm, and smoother than Taichi could have imagined. She guided his hands further up her body until his hands were resting on her breasts.

Taichi couldn't take it anymore. He gave in.

He began to feel her breasts through the thin bra, and Hikari's small moans of pleasure lit a fire inside him. He realized that there was no turning back, not at this point, and he slid his hands around her sides to her back and, after a moment of fumbling, unclasped her bra.

"Now you're getting it," said Hikari, grinning. She slid the straps of the bra off her shoulders and let it fall, revealing a modest but perky pair of breasts that were capped with small, erect nipples.

Hikari then straddled Taichi's leg once more and began to unbutton his shirt, her skin brushing against Taichi's incredibly-sensitive cock and sending electric shocks through his whole body. 

She had his shirt unbuttoned soon enough, and he wriggled out of it, leaving him nude and Hikari clad only in her panties and kneesocks. Hikari began to rock her hips, grinding her pussy against Taichi's leg, and pulled him in for another kiss with one hand while the other began to stroke his exceptionally-hard cock.

Both of them began to let out soft moans, and Taichi's reservations disappeared as he saw how amazing it felt to be pleasured by his own sister. Something he had guiltily fantisized about for so long was finally happening for real, and it was better than he could have imagined.

And that was before Hikari knelt on the floor in front of him and began to give him a blowjob.

She sucked and licked and lapped at her brother's cock like it was the only thing in the world, and it felt that way to Taichi too as all of his body's sensitivity seemed to concentrate at his dick. It felt so good it nearly hurt, and when Hikari began bobbing up and down on it, the head hitting her throat, Taichi lost control of himself.

In a flash of movement he grabbed Hikari's head with both hands and shoved her down onto his cock, forcing her to take it into her throat while he stood up and thrust as deep as he could go, letting out a cry of "I'm cumming!"

And he did. Thick spurts of cum shot out of his dick directly into his sister's throat, and it kept coming for longer than Taichi had thought possible. He regained control of his muscles and eased out of her throat, still cumming, and shot another spurt into her mouth on the way out.

Hikari pulled back, coughing, but she waved Taichi's frantic apologies away. "No," she said, having regained her breath. "Don't apologize. You took initiative. I liked it. But, in the interest of fairness, I think it's your turn to give me oral."

Kari stripped off her panties and lay down on the couch, spreading her legs and revealing her puffy, drooling pussy. Her crotch was free of hair, and her labia were swollen and pink.

Taichi's head shot forward and he began to eat out his sister's pussy with a frantic energy, so wrapped up in what he was doing that he barely noticed Kari's shaking or her quivering moans.

And she tasted amazing. Something about the taste of her cum enthralled him, drove him to take in more and more. And Hikari's pussy was happy to give him all the juice he could handle, she was exceptionally wet and getting more so with each passing nmoment. Her pussy was also highly responsive, twitching and pulsing as her pleasure grew, her cute little clit stiffening and her entrance opening and closing on its own, hungry to be filled.

Taichi went hard and fast, the sensation almost overwhelming Hikari from the sounds of her increasingly incoherent moaned encouragement. It wasn't long before Hikari's hands were tangled in Taichi's hair, jamming her pussy into his face as she bucked and writhed.

"Taichi," she cried out. "I'm cumming!"

And cum she did. What followed was a long, loud, shaking orgasm that left every muscle in Hikari's body tensing and loosening in waves, her moans almost a whine of pleasure.

And Taichi, hungry for the new flood of cum leaking out of Hikari's pussy, kept going. Slower, gentler, but still insistent.

About thirty seconds after her first orgasm Hikari enjoyed a second at her brother's hands, her overly-sensitive pussy exploding with sensation as the waves of climax rolled through her, one after the other.

Finally Taichi stopped, bringing his face up to reveal a manic look in his eyes and his mouth and chin covered in Hikari's cum. She took his head and pulled him towards her, putting him on top of her as she drew him into a deep, passionate, holy-shit-that-was-amazing kiss.

The kiss went on for a long time, Hikari tasting both her brother and herself, but she soon became aware of the thing poking her inner thigh. Taichi was hard again, and it felt even more rigid than ever.

"I think we need to do something about that," Hikari said, reaching down and finding Taichi's cock with her hand.

"Y-yeah," said Taichi, gasping for breath, his heart going a mile a minute.

Hikari began to move her hips, putting her pussy into place as she guided Taichi's cock towards her pulsing entrance.

"Wait," Taichi said, looking her straight in the eye. "Are you sure you want to do this-"

"Oh, shut up and fuck me, Taichi," said Hikari, rolling her eyes. "I've wanted this for too long to stop now."

"Me too," said Taichi, who pulled her into another kiss as he plunged inside her, sinking his entire length into her in one go.

The pleasure was tremendous, and both of them broke off the kiss to let out loud, wavering groans that expressed how they felt far better than any words could.

Taichi immediately began to thrust, plunging in and out of his siste with a passion. Even though he had already cum once, he was so aroused that he felt he could go forever. Hikari, for her part, was writhing in pleasure, the sensation of beingfucked mixing with the sensitivity left behind by her shotgun orgasms to create a feeling so strong she could barely thnk, let alone speak. Her eyes unfocused and began to glaze over, her face flushed and breathing heavy, her tongue hanging out of her open mouth, a trickle of drool stretching from the corner of her mouth to her cheek to the surface of the couch.

Taichi wasn't in much of a better state, his primal urges having completely supplanted any anxieties he might have had about having sex with his sister. It felt far better than any moral quandry, and by that logic it was clear what the better option was. So he fucked her, hard and fast, cuickly bringing himself to the edge of orgasm.

"Hikari," he grunted, "I'm... I'm gonna cum."

Hikari's eyes regained some of their clqarity as her thoughts resurfaced, and between the moans she was able to get two intelligible words out - "Cum inside."

-

Throwing caution to the wind, Taichi did so. As he plunged inside her for one final, strong thrust he let out a deep groan of pleasure and rode the wave of his orgasm, feeling the hot seed pumping out of him and deep into her waiting pussy, the semen coming in wave after wave as he filled her up. Hikari moaned, savoring the feeling of taking in his hot cum.

Taichi's orgasm finally came to an end, his blood pumping wildly as he eased his way out of Hikari's pussy, a trail of cum leaking out as he pulled free from her. He flopped backwards, pulling Kari along so that she ended up on top of him, stroking his chest as she felt the cum seeping out of her freshly-fucked pussy.

She kissed him then, a long, passionate kiss. Not a wild sex-driven kiss, but a lovers' kiss.

Taichi looked at his sister with his soft brown eyes. "Tell me something, sis."

"What is it?"

"Were you planning on this?"

Hikari chuckled. "I've known about that porn stash for years. Decided it was time to stop waiting for you to make a move." She nuzzled up to him, making contented noises not unlike a cat's purr.

The two of them fell asleep like that, lying on the couch while the forgotten porno's menu screen played on repeat.
