Chapter 2 - One More Slip

To say that Tai and Kari's walk home after Mimi's fateful party was awkward would be to make a molehill out of a mountain.

After all, the two of them had, mere minutes before, fucked each other in a closet blindfolded, not knowing who the other was at the time. They had been a perfect match, with sexual compatibility off the charts, and when the blindfolds had fallen off and they realized what they had done...

Well, they did it again.

So yes, it was an awkward walk home. They very carefully didn't talk about what had just happened, didn't say much at all. Although occasionally the oppressive silence became too much to bear.

"So..." Tai said, clearing his throat. Kari looked towards her brother, her eyes wide, and Tai continued. "Our, uh... mom and dad are both still out of town, right?"

"Yeah," Kari said hoarsely. "Dad's on his business trip until Friday and mom's still visiting her parents."

"Good, good," Tai said, unsure of why he said it. The two made eye contact, then looked away from each other, blushing hard.

"I, um..." Kari said a few minutes later, trailing off as quickly as she started to speak.

"Yeah?" Tai asked. Kari couldn't seem to muster the words, however. Instead she stepped closer to her brother, wrapping her arm around his. Tai tried not to think about the warmth of her body, the redness of her lips in the cool night air, the way his pants were beginning to tent.

He tried to ignore all these things, and completely failed. His mind kept returning to the sight of a nude, orgasming Kari underneath him, moaning out in pleasure from the hot cum he had pumped inside his own sister.

The two gripped each other a little harder as they neared the Kamiya household.

And then, after an uncomfortably long silence, their building came into view. The two started walking faster, to the point where they were both powerwalking to the door. Tai shakily took out his key and unlocked the door, opening it and stepping aside to let Kari in.

He followed her inside, shut the door behind him, and as soon as the door latched shut Kari was on him, wrapping her arms around him and standing on her toes to kiss him with furious energy. Tai held back for a moment, but then he was all over his little sister as well, making out with Kari passionately as she pressed him against the door. His hands found her tight ass and squeezed, and Kari did the same to him. Her tongue snaked into his mouth, and the two let out simultaneous moans as they began to explore each other.

And then, in a swift movement, Tai pushed Kari away from him and cleared his throat, blushing hard and unable to make eye contact.

"I, um..." he said, stammering.

"Yeah?" Kari asked, looking worried.

"This... us... It has to stick to tonight, right?"

Kari gulped, then said "Yeah. Tonight."

Of course, both of them knew that was a lie. But it was what they needed to tell themselves and each other. If they placed a restriction on it, the taboo became, well, a little more acceptable. And there was no way the two of them could avoid going at it again, so they agreed to keep it to that night.

With that, Tai stepped forward and kissed Kari again, a kiss full of passion and tenderness that Kari readily reciprocated. Then, Tai picked his sister up, her small frame easy for him to lift as he carried her bodily towards his room.

He opened te door, carried her inside, and set her down on his bed. He clambered on top of her and the two began to make out again, Tai groping his sister's breasts and Kari pawing at her brother's crotch, feeling the long hard erection through his pants.

Tai pulled back enough to slip Kari's sweater off of her, with Kari lifting her arms to make it easier. He tore off his own shirt, hearing a slight ripping sound as he removed it but not caring in the slightest. Then he backed off and slipped his pants and underwear off, his erection springing free, long and hard and already dripping with precum. He stepped out of his pants and then pulled down Kari's skirt and panties, hands sliding with longing across her tender flesh.

While Tai took his sister's panties off, Kari was busy removing her bra and letting her breasts fall free. Tai climbed back on top of Kari, their now-naked bodies sliding against each other as Tai's hand found Kari's hot, wet pussy and began massaging the outside while Kari began to rub Tai's hard dick.

The two broke off and looked at each other for a long moment, admiring the lean, toned bodies that they had both developed over the years. They were both quite good-looking, and the haze of attraction only served to make them look even better to each other. It felt wrong, especially for Tai, to be looking at his little sister this way, to be touching her this way. But it also felt far too right to ignore, and he knew that there was no backing out.

Kari slid out from under him after planting a kiss on his lips, as if reading his mind, and the two traded places as Kari got on top of her brother and brought herself down to where she could reach his cock with her mouth. She gave it a long, slow lick from the base to the tip, looking her brother in the eyes as she began to suck his cock.

This time Kari had the benefit of being able to see her brother as she sucked him off, and she was grateful for it for more than one reason - she loved seeing her brother as she fellated him, but also she was able to see his reactions as she tried out different approaches, finding what seemed to work best for her big brother. She tried pumping the shaft with her hand while she kissed and licked his weighty balls, she kissed and licked along the shaft, but what he responded to best - judging by his gasps and sudden tensing-up, was a fast and sloppy blowjob, which Kari was more than happy to give.

She worked her way up and down Tai's cock with gusto, spit flying and precum dribbling into her throat as she bobbed up and down on his dick with more enthusiasm than she had ever had in a blowjob before.

Tai, for his part, was appreciating it greatly. His hand reached down to Kari's head, resting on her hair and beginning to stroke her short hair in something between brotherly affection and pure lust. Kari, meanwhile, was using one hand to play with Tai's heavy, big balls and using the other to finger herself, still feeling Tai's cum inside her from the party.

Kari only got more and more into the blowjob the longer she went, and her eyes began to glaze over as she shoved herself down, deepthroating her brother's cock and sucking him within an inch of cumming. Right as she sensed that he was on the verge of orgasm, however, she pulled back quickly. Tai made a confused nose, but then let out a satisfied groan as she straddled him, dripping pussy hovering over his cock, and she leaned down to kiss him. After breaking off the kiss she brought her mouth to his ear and tugged his earlobe between her teeth ever so gently, then whispered "If this is only tonight, then I don't want your cum going anywhere but my pussy..."

Tai gulped and nodded. He kissed her back and then rolled them both over, pinning Kari underneath him and positioning his cock at her quivering entrance.

And then, ever so slowly, he eased his hard cock inside his little sister as she whimpered and he groaned in pleasure.

As soon as he was inside her to the hilt, however, he realized that he couldn't hold it in anymore and he muttered something Kari couldn't hear as his cock twitched inside her and pulsed, letting out several waves of hot, sticky seed in quick succession.

"S-sorry," Tai stammered. "It's just, seeing you like this..."

"Kari reveled in the feeling of the cum splashing inside her, however, and she craned her neck to kiss Tai on the lips, flicking her tongue into his mouth and then pulling back.

"I don't mind," she purred. "I'm glad you like me that much. As long as you have more in you..."

Tai looked down at where the two were joined, realizing that he had not softened in the slightest after cumming, and he nodded, smiling.

"Good," Kari said, pulling Tai's head down to kiss him as he began to thrust in and out of her, their fluids mixing in her pussy and lubricating things even more, not that it was needed - Kari was as wet as a river by this point.

Tai quickly picked up speed as he fucked his little sister, going from a slow in-and-out to a rapid thrusting that drove both of them wild. Kari began rolling and bucking her hips in rhythm, not even doing it consciously, and the two of them quickly found a pace that worked well for both of them.

This time it was Kari's turn, and she felt the orgasm cresting inside her as Tai fucked her relentlessly. "T-Tai," she stammered. "I'm gonna cum, I'm gonna cum..."

Kari's movements, as she said the words, became frantic and uncontrolled. Her whole body quivered, her muscles tensed, and her pussy - her wonderful, tight pussy - was pulsing and tightening in joy around her brother's cock.

And then, as Tai went faster and harder, pushing her over the edge, came the crescendo.

"Tai," she shouted, unable to control her volume. "I'm cumming!"

And with that, she did. Her already-tight hole tensed, clamping down on Tai's big, throbbing cock, and she let out a wail of pleasure as she shook and bucked her way through the strongest orgasm she could remember. She felt like a boat in a stormy sea, a ball in a pachinko machine, as the orgasm rocketed through her entire body at once.

What's more, she felt a sudden pressure inside her and, wailing again and unable to hold it, let go of her control and squirted all over Tai and Tai's bed.

The cum jetted out of her, intensifying her orgasm and extending it, with Kari a blank-eyed and drooling mess by the end of it.

Tai pulled out and held himself over Kari, looking at her with an expression of both lust and love. He realized that this may be wrong, but it felt like the writest thing in the world. He leaned his head down and kissed his little sister on the lips, which brought Kari back from her near-catatonic post-orgasmic reverie. Her eyes cleared and she looked up at him, the fog replaced with fire. She kissed him back, pouncing upward in a way that the two suddenly switched places, Tai rolling over onto his back and Kari scrambling on top of him.

Kari perched atop Tai's groin, his dick sandwiched between his belly and her dripping pussy. She began to rock back and forth, sliding her slit along its length, and she leaned down and began to shower her brother with kisses - on the lips, the cheeks, the forehead, the collarbone, and everywhere else she could reach.

Tai's hands wandered upwards and cupped his sister's breasts, massaging them as they both moaned in pleasure. Then, in a move of incredible smoothness, Kari lay flat on her brother's chest, sliding up and then down such that his cock entered her pussy once more, sliding in with graceful ease as they both groaned, ecstatic.

And then, Kari took the lead by bouncing her hips up and down, straightening up and holding Tai's hands to her breasts as she went. She fucked her brother, then, and with everything she had in her. Tai was along for the ride on this one, and he reveled in the pleasure as he tried to keep up. His hands massaged her breasts and pinched her nipples as he watched her, moving his hips in time to her bouncing, seeing his little sister riding him harder than he could recall ever being ridden before. He was having no problem's staying hard - in fact, he was so hard it was almost uncomfortable as his cock went as rigid and long and thick as was possible while he felt his balls growing heavier, filling with hot seed ready to pump inside his relation.

His hands slid, lovingly, off of Kari's breasts and around her back. He pulled her down close to him, not breaking her stride in the slightest, and let out a hoarse whisper.

"Sis, I'm gonna cum again."

Then he kissed her, and as his lips met hers he bucked his hips upward, driving as deep inside her as he could go and moaning into her lips, arms wrapped tight around her, as he pumped Kari full of hot, sticky cum. His hips stayed in the air, shaking from the tension of the orgasm and from holding Kari up, as his ample balls emptied their contents inside his little sister, the best cum of his life.

Kari, meanwhile, whimpered and shook as she felt her brother's hot seed pouring inside her, almost reaching another orgasm from the feeling of having Tai paint her insides white, filling her up.

And then, because no one moment can last forever, Tai's flow began to slow and he slowly released the coiled tension in his body, breaking off the kiss and letting out a deep sigh as he rode out the final aftershocks of his climax.

And then, finally, his dick began to soften. He slid out of Kari's pussy, releasing a stream of cum that had been plugged inside her. The two held each other tight for minutes that felt like hours, and slowly they began to release each other. They did not break contact, however, Kari shifting to get as comfortable as she could cuddling her brother, feeling his naked body with her hands, feeling the cum flow out of her pussy.

"I, uh..." said Tai, then cleared his throat. He did not continue.

Kari kissed him on the cheek and nuzzled his face. "You okay, bro?"

"Yeah, I... yeah." Tai said, flushing more than he already was. "You?"

Kari's hands traveled down his chest, across his abs, down to his groin and the now-soft cock that had so recently pumped her full of cum. There was still a droplet of his seed on the very tip. She scooped it up with her finger and brought it to her mouth, savoring the taste.

"Yeah," she said. "Never better."

The unlikely pair lay there for a while, breathing heavily and slowly, gently touching each other with tenderness. Each of them was lost in thought, wondering what was next for them. They had agreed to keep it to that night, but how likely was that? And did they want it that way?

And then, slowly, practicality gave way to contemplation. They realized that both of them were covered in sweat and in cum, as were Tai's sheets.

"We should... probably strip the bed and shower," Tai said, one of his hands cupping his sister's left breast.

"Yeah," Kari said. "In a minute." Then she took hold of both of Tai's hands with her own. She intertwined her fingers with one, and brought the other down to her pussy, the post-coital oversensitivity of which had given way to further desire.

Tai felt his sister's heat radiating from her core, and he outstretched two of his fingers and began to toy with the outside of her pussy, playing with the folds and with her clit, lubricating her with the cum that remained in and around her pussy.

Then, slowly, he slid a finger inside and began to stroke the inside of her pussy, Kari moaning in pleasure and encouragement,. She removed her hand from where Tai was fingering her and navigated towards Tai's cock, stroking it up and down as it began to harden once more.

As Kari grew more wet and Tai grew harder, the two began to speed up, with Tai slipping another finger inside his sister and Kari wrapping her nimble fingers around Tai's shaft and beginning to pump up and down.

The two began to breathe heavily. Breathing gave way to groaning, which transitioned into moans of pleasure. As they grew hornier they sped up even more, until they were both going hard and fast.

Then the two of them made eye contact and, in one moment, let go of each other's parts. Tai craned his neck to give Kari a kiss on the cheek, and they both started giggling uncontrollably.

They got out of the bed, then, and efficiently stripped the cum-stained blanket and sheets off of the bed, as well as the drool-covered pillowcases. These were tossed, unceremoniously, into Tai's hamper, and the two of them looked up at each other's nude bodies.

"You know," Tai said, voice husky. "The news said there's a bit of a water shortage."

"Yeah," Kari said.

"Maybe we should... you know, shower together. Save water."

The two of them started giggling again, and Kari took Tai by the hand and led him towards the bathroom, where Kari turned on the shower and they both waited for the water to heat up. They faced each other, standing close enough that Tai's hard cock poked up against Kari's belly, and they leaned forward and kissed each other.

Their arms both wrapped around the other as they kissed, the makeout growing from a tender kiss to a serious makeout session as they stepped closer to each other, the sound of the shower providing soothing white noise as their bodies rubbed up against each other and they both lost track of time and place.

It was only when they broke off the kiss and opened their eyes did they realize that, in their reverie, the bathroom had grown warm and foggy with steam. They stepped into the shower together, letting the hot water cascade over their gloriously naked bodies, and held each other close, allowing the water to wash away the sweat and cum on their bodies.

They embraced, and they kissed, and hands slipped from backs down to butts as they reveled in each other and the hot water.

"I don't think we're saving water," Kari whispered, standing on her toes to give Tai's earlobe a light nibble before speaking.

"I know," Tai whispered back.

Tai then broke away and grabbed soap and a washcloth off of their places in the shower. He lathered the soap on the cloth and slowly, tenderly, brought it to Kari's skin, where he began to wash her.

Kari relaxed into it, enjoying the sensation of being cleaned.

"I can't remember the last time we washed together," Tai said, half to his sister and half to himself.

"I can," Kari said, looking down and blushing.

Kari turned and moved to allow Tai to wash her, and before long she was squeaky clean once more. Tai wrung out the cloth, and Kari snatched it out of his hand, preparing to wash him next.

Tai relaxed his muscles and allowed his little sister to wash him, taking deep and even breaths as he moved to accomodate her. In short order he was clean too, and the two stood, facing each other, close enough that Tai's erect cock and Kari's breasts brushed the other's bodies.

Tai looked deep into his sister's eyes, the rest of his world shrouded in steam, and he stepped closer. He wrapped one hand around Kari's waist and cupped her pussy with the other, and then he kissed her with all the romance and passion he could muster.

Kari melted into him and into the kiss, and she barely even noticed as he slipped two fingers inside her once more and began to gently slide them in and out.

Kari moaned as Tai began to grow faster, more assertive. She loved the sensation of being fingered in the shower, but she wanted to do her brother one better.

As such, she gently pulled his dexterous fingers out of her and lowered herself to her knees, Tai's body blocking the majority of the shower head's spray. She brought her hands and face to Tai's erect cock, nuzzling it with her wet cheek while she used both hands to massage his weighty balls. From there she moved one hand to the base of his shaft, wrapping it most of the way around with her thumb and forefinger, and cupped his balls with the other. Then she opened her mouth, droplets of water splashing into it, and began to suck her brother off with all the artistry she could muster.

She focused on the head and balls this time, occasionally surprising him with a rapid deepthroating. Before long Tai was groaning and gasping, trying to grab the smooth tiled wall for support.

Kari could tell that if she kept this up he was going to cum soon, but as she had said she wanted it all in her pussy tonight. So she stood up, turned around, and braced herself against the wall while sticking out her ass, making herself available to him.

Tai took her up on it immediately, grabbing her by the hips and plunging all the way inside Kari in one smooth stroke.

He began to fuck her again, knowing that he didn't have more than one orgasm left in him for the moment and determined to make the last one count.

He went fast and hard, his cock covered in Kari's wetness, sliding in and out of her with ease. They both gasped in pleasure, loving the way they felt to each other as Tai fucked his little sister doggystyle.

"K-Kari," Tai grunted as he fucked her. "I, I lo-"

"I love you too, brother!" Kari wailed. "Now cum! I want to feel you shoot everything you have into me... please."

Tai was far too courteous to deny a request such as this, and his little sister's words were what he needed to fall over the edge into the waterfall of orgasm, letting out a shout of "Cumming!" as he plunged inside her for the final time, feeling his balls twitch and empty as they pumped shot after shot of hot cum into Kari's waiting pussy.

This, in turn, was exactly what she needed and she let out a shout of "I'm cumming too!" as her knees nearly buckled and every nerve in her body was set ablaze as she felt her big bro pump her full of his hot cum.

Tai slowly slid out of his sister, cum beginning to leak out of her pussy once more, and they both dropped to their knees in the shower. Tai wrapped his arms around Kari from behind and hugged her, and the two remained like that for a long while.

But, of course, eventually the hot water began to cool and they came to, stepping out and turning off the shower and toweling off.

Kari pulled her brother toward her own room, and the two got into the bed. They snuggled up to each other under the covers, neither of them wearing pajamas, falling asleep to the feeling and sound of each other.
