Chapter 1 - Cleaning Duty

The size of TK's dick was something that everybody in the school had some inkling of, but that nobody talked about.
 
That had begun to change, however, as the majority of TK and Kari's graduating class turned eighteen, and whispers in the halls and significant looks spoke of amazement and, sometimes, fear. There were rumors that TK wore sweatpants instead of basketball shorts during his games was that the usual uniform didn't fully cover him, and indeed the young man did seem to favor loose-fitting pants, especially recently.
 
Something everybody also knew was that TK and Kari wanted to date each other, but after almost the entire duration of high school it still hadn't happened. TK, for whatever reason, seemed far too hesitant to ask her out, even as things got incredibly flirty between the two of them. TK would always pull back at the last moment, blushing, and change the subject. Despite his odd behavior, it was obvious that they shared a mutual attraction and love.
 
The truth was that TK had refused to ask Kari out because of his dick - which the rumors, if anything, understated. He was terrified that Kari would panic and leave him at the first sight of it, and he didn't want what he considered to be a curse to ruin things between the two of them.
 
Little did TK know, however, that Kari was well-aware of the monster in TK's pants - no matter how well he tried to hide it, it was impossible to know him for years, watch him grow into manhood, and be unaware of it.
 
What's more, Kari was not only aware of TK's insane endowment. Not only that, but she had fallen into a nightly routine of masturbation, imagining TK pounding her with it. She had gotten sick of TK's refusal to ask her out, and had resolved to take the next opportunity she got, no matter what.
 
That opportunity, as it happened, came about a week later.
 
...
 
TK and Kari were always paired up, by their classmates and even by their teachers, and the two were assigned their turn to stay late at school and take care of classroom cleaning duty. The room was a bit of a mess, and by the time they were nearing completion the school was as good as empty, with both students and faculty already having left for their homes.
 
This particular evening happened to be capping off a hot and sticky summer's day, even the light cleaning duty leaving the pair flushed and a little sweaty.
 
"Phew," said Kari as they finished their task, stretching in a way that was not overtly sexual, but nevertheless showed off her large breasts straining against her tight uniform shirt. "I need some water."
 
TK wanted to be a gentleman, but he couldn't help staring a little. Kari had been a late bloomer, but when her breasts grew, they grew large - the largest rack in the entire class and even bigger than Sora's - although not quite as big as Mimi's.
 
"Yeah," said TK. "Good idea." He was fighting off getting a boner as hard as he could, and he needed a moment alone to readjust. "Why don't you head on out to the water fountain and I'll be right behind you, as soon as I finish this up."
 
Kari did so, and TK had a few moments' reprieve in which to adjust his enormous package so as to not make it quite so obvious that he was at half-mast. Then, just as he was finishing up, a yelp from the hallway and Kari ran back into the classroom, arms crossed over her chest and her cheeks burning.
 
"What happened?" TK asked. "Are you okay?"
 
"Yeah," said Kari. The fright eased from her face as she spoke, slowly replaced by the grin of someone who has just had an opportunity fall into her lap. "I was drinking from the tap, and I guess the pressure went crazy because it soaked my shirt..." She then uncrossed her arms, revealing her wet, white uniform shirt. It clung to her and had turned nearly transparent, revealing Kari's large breasts contained by a lacy pink bra.
 
TK's eyes widened, his heart raced, his jaw dropped slightly - and his dick grew.
 
He felt the familiar rush of blood to his cock as it quickly expanded, sliding down his leg, his cockhead growing more sensitive as it moved past the silk of his boxers to the rougher material of his uniform pants.
 
TK's face paled as his dick swelled to full size. He looked at Kari's eyes, which were firmly locked on the thick rod running down his pants leg.
 
Kari gently chewed her lower lip, staring at the incredible bulge, knowing that her chance had come. She grabbed him by the shoulders and pulled him in close, kissing him with everything she had. TK froze, shocked, but after a few moments his lips softened and he began to reciprocate. She slid her tongue into his mouth, exploring it extensively.
 
Things began to heat up quickly, with Kari initiating by frantically unbuttoning his shirt. TK did the same to her, peeling the wet fabric from her skin.
 
Kari moved her hands down to the monstrous cock straining against TK's pants, trying to get a grip on it.
 
"Mmm," she moaned between kisses, "it's so thick I can't even get my hand around it..."
 
She had intended to excite TK even more, but the opposite seemed to happen. He froze, stopping their makeout session, and stammered.
 
Kari decided that what he needed was some pleasure to get over his fears, so she dropped down to her knees and undid TK's pants, pulling them and his boxers down.
 
TK's cock, now fully hard, sprang free from his pants and almost hit Kari in the face. TK looked mortified, but Kari was only aroused as she brought her hands to his now-exposed dick and began to pump her hands up and down the incredible length of the shaft.
 
TK remained frozen, but his body responded more than positively. Kari moved one of her hands down to his enormous balls, weighing each of them in her hand and finding them heavy and swollen.
 
"It's amazing," said Kari, enraptured by the sight of it. "It's even bigger than I imagined. Bigger than Tai's..."
 
TK blinked, seeming to snap out of his petrification. "How do you know Tai's..."
 
"We live together, silly," said Kari with a giggle. "We've accidentally caught each other masturbating more times than I can count."
 
"Anyway," Kari continued, licking her lips between statements. "I know that I'm really turned on, and you clearly are too. We should do something about that..."
 
"Y-yeah..." said TK, gulping.
 
"Particularly in your case," said Kari, standing up and continuing to stroke TK's erection. "I don't think you'll be able to fit that back into your pants in this state."
 
Kari kissed him again, and TK seemed to forget his fears, kissing her back and beginning to push her towards one of the desks. As they approached it the two of them stripped off the remainder of their clothes, Kari's weighty breasts popping free from the restrictive bra - the sight of which only aroused TK even more. They completely forgot where they were, having eyes only for each other.
 
TK ripped off Kari's panties, her last remaining article of clothing, and grabbed her round, supple ass with both hands, lifting her onto the desk.
 
From there TK began to grope Kari's large breasts, something he had wanted to do for a long time. He was almost as enraptured by them as Kari was by TK's cock, which was at that moment poking against her thigh. Kari enjoyed it, but after a few minutes she desperately needed more. She guided one of TK's hands down to her hairless pussy, at which point he began to enthusiastically, if not expertly, finger her.
 
TK brought his head down to Kari's free tit, kissing and sucking on it and gently biting the nipple, which only made Kari even more wet and horny. She began to move her hips, grinding her pussy against TK's fingers.
 
"Mmm," said TK, pulling his head back from Kari's tit. "Your pussy's so smooth..."
 
"Do you like it?" asked Kari, the blush on her face growing slightly.
 
"Yeah," said TK, barely able to get words out, he was so distracted by exploring Kari's body.
 
"I'm glad," said Kari, looking down. "I wax it because I thought you'd like it. All the girls in Tai's porn and hentai are hairless, so..."
 
"It's wonderful," said TK, who proceeded to get down on his knees and moved to eat Kari out.
 
TK didn't really know what he was doing, but in exploring her pussy frantically with his tongue he managed to hit many of her sensitive spots, and he found that Kari was especially responsive and moaned the loudest when he circled his tongue around her erect clit. He began to focus on that spot, and what with how worked up she already was it wasn't long before she whimpered out the magic words.
 
"TK," she said. "I'm... I'm cumming!"
 
TK felt her muscles spasming, and a small jet of fluid hit his face as Kari squirted a little.
 
Kari slumped on the desk, savoring the sensation of being given an orgasm by someone else for the first time. She recovered in admirable time, however, and hopped back off the desk, pulling TK into a deep kiss, tasting her own juices on his lips and tongue.
 
She proceeded to pull out a chair and pushed TK into sitting on it and opening his legs. Kari got on her knees, between his thighs, and compared TK's monstrously-large cock to her forearm. It was longer than the distance from her elbow to her outstretched fingers, she guessed it may have been as long as twenty inches, and it was thicker than her fist.
 
"It's amazing," said Kari, chewing her lower lip again. She moved her head to his weighty balls - which, if anything, had swelled even more - and began to lick and suck on them. TK groaned in pleasure, and she slowly worked her way up, along the shaft, coming to the tip after what felt like a joyous eternity.
 
Kari then took the head into her mouth...
 
And then she stopped.
 
She had managed to get the head, which was dripping salty precum, into her mouth. But she wasn't capable of going any deeper, it was just too big.
 
Kari had been fantasizing about giving him a proper blowjob, but that was clearly impossible. So she came up with a plan B, wrapping her voluptuous tits around his throbbing dick and bouncing them up and down while she sucked on the head.
 
TK was more than satisfied, rolling his head back in pleasure and groaning, his dick pulsing. Kari's movements were inexpert and sloppy, but for TK, who had only been pleasured by himself before, it was heaven.
 
Kari worked over TK's dick as hard as she could, and it wasn't long before TK felt an orgasm of his own coming.
 
"K-Kari," he said, "I'm-I'm gonna cum."
 
This only encouraged Kari to work even faster, drawing an orgasm out of him as he moaned in pleasure.
 
Kari felt the first wave of hot, salty cum shoot into her mouth. And the next.
 
And the next.
 
There seemed to be no end to it, and before long Kari's mouth was entirely full. She pulled her head back and swallowed as much as she could, holding the dick to her mouth so that as much of it went into her as possible, but there was simply so much of it that her face and tits were quickly covered by TK's hot spunk.
 
TK's head rolled back and he panted in pleasure, but his cock didn't show any signs of shrinking. Kari climbed on top of TK, positioning the still-dripping cockhead against the entrance to her virgin pussy, and said "You can go for more, right?"
 
"Yes, but... Kari, it's not going to fit."
 
Kari, not one to shrink from a challenge, licked up the cum coating her lips and smirked. "We have to try."
 
Despite her bravado, Kari was quite nervous. She looked down and compared TK's dick to her tight pussy and wondered if it really could go in. But, like she said, she had to try. She needed to feel his big cock inside her, pounding her like she had fantasized about so many nights.
 
Kari began to ease herself downwards, and to both hers and TK's amazement her vagina began to stretch out, accepting the very tip of TK's cockhead. Kari felt a twinge of pain, this being her first time being penetrated - and by such a large cock, at that - but the pain of popping her cherry was far outweighed by the pleasure of being filled - and not even all of TK's bulbous cockhead was inside her yet.
 
Kari eased herself downwards, letting gravity and the incredible wetness of her pussy do their work.
 
And, to both of their shock, it worked. Inch after inch of thick, hard dick slipped inside Kari's dripping-wet pussy, both of them groaning in pleasure.
 
The way that Kari's walls had to stretch around TK's massive cock was kind of painful, yes, but the same thickness that caused the discomfort also stimulated all of her sensitive spots at once, the pleasure overriding the pain by a huge margin.
 
Kari continued to sink down onto TK's dick, holding him tight and moaning and crying out, until eventually they hit a wall. A bit less than half of TK's dick was inside her, and she was just starting to move more quickly when she felt the tip of TK's cock press against her cervix.
 
The sensation was too much for Kari to handle and she came again, moaning loudly and squirting all over TK while her walls clenched tight around TK's throbbing cock.
 
Kari took a moment to recover, and then she looked into TK's eyes and said, breathlessly, "Fuck me."
 
TK, worried about hurting Kari but also hornier than he had ever been in his life, gulped and nodded. He began to move his hips, and Kari began to bounce up and down on TK's mammoth cock.
 
Both of them were nearly screaming from pleasure, and every time TK's cockhead hit Kari's cervix she felt it going a little deeper. She looked down and saw that, every time he made contact with her cervix, a bulge formed between Kari's hips and her belly button.
 
She pointed this out to TK, caressing the bump, and TK became extremely worried. He asked if she wanted to stop, but Kari responded with an emphatic "No."
 
Both of them more stimulated than they had ever been, it wasn't long before they both felt orgasms building inside them.
 
"I'm going to cum again," said Kari, gasping.
 
"M-me too," grunted TK, looking like he could barely keep his eyes focused it felt so good.
 
The new couple came together, moaning in ecstasy as the orgasms rocketed through their bodies. It turned out to be more than they had bargained for, however, as Kari's legs collapsed from under her. That, combined with an completely involuntary upwards thrust from TK, combined to push TK's cock through Kari's cervix and directly into her virgin womb.
 
A second wave of pleasure crested through Kari as she felt the entirely unique sensation of having her womb penetrated, crying out and gasping as TK's cock stretched out her womb.
 
Then TK came in earnest, and he released his load directly inside Kari's virgin womb, causing it to fill and stretch even more.
 
Kari very nearly blacked out from the rush of sensation, but she regained her senses and looked at TK, who was looking at her with a panicked expression.
 
"I'm going to pull out," said TK, his voice full of concern.
 
"No, please," Kari begged, looking TK in the eye. "I want you to keep fucking me. Please. I need this."
 
"But your womb-"
 
"I want you to fuck me," said Kari insistently, and TK gulped, but nodded.
 
He picked Kari up with little effort as he stood up, his legs shaking. Kari could feel TK's cock and his cum stretching out her pussy and womb, and she was so focused on the sensation she hardly noticed TK setting her down on a desk, staying fully inside her the whole time.
 
When he put her down, however, they both looked at Kari's belly and saw that the bulge was now past Kari's belly button, half of his cock in her womb and the other half in her pussy.
 
The two began to rock their hips in time with each other, Kari screaming and squealing in pleasure as TK fucked her womb. He only ever pulled out far enough that his cockhead remained in her womb, so as he fucked her every square inch of Kari's pussy was being stimulated all at once. The two found a workable rhythm and TK met Kari's squealing with his own groans of pleasure, not sure that he would be able to stop at this point.
 
As he fucked her, TK also saw his own cum leaking out of Kari's pussy, the pressure forcing it out around his cock and providing additional lubricant as they fucked, the pair going as fast and hard as they could stand.
 
Kari's eyes rolled back in her head and she lost control of her limbs, which flailed about as their hips rocked and gyrated. The noises she made became less and less coherent, with only the occasional "More," surfacing from the sea of moans and wails.
 
TK did his best to provide, and Kari enjoyed a series of shotgun orgasms as TK built to a climax of his own.
 
"Kari, I'm-I'm gonna cum again," he said, gasping for air.
 
Kari's moans and whines resolved into words once more. "Do it inside!" she cried out, her legs wrapping around TK's hips and forcing him to stay inside her.
 
Her words continued, gibberish spattered with words of encouragement, telling him how big he was and how amazing it felt and how please, oh god please he had to cum inside her. Her eyes were glazed over, her senses lost in favor of pleasure, and she was drooling profusely onto the desk as she begged TK to cum inside her.
 
TK obliged her, giving the final few thrusts and then burying himself all the way into Kari's womb, stretching it out and making a huge bulge in Kari's stomach.
 
Then his climax hit, and he felt shot after shot of hot cum pouring inside Kari's womb, stretching it out even more and making Kari's stomach look inflated. The sensation of being so thoroughly filled ripped one final orgasm out of Kari, who screamed and actually blacked out for a moment.
 
She came to within a few second, and the two looked at each other, then the incredible bulge that filled Kari so much she looked pregnant.
 
Kari's legs unwrapped and let TK's hips free, and he began to ease his way out of her carefully. Kari moaned as he pulled out, eyes rolling as he exited her womb and began to pull out of her pussy.
 
After a small eternity he finally pulled his cockhead free, and a fountain of cum proceeded to flow out of Kari's pussy. Even more stayed inside her, however, her stomach still bulging slightly from all the cum inside her.
 
The two took a few minutes to rest, holding and kissing each other tenderly, and then they set about the daunting task of cleaning up both themselves and the re-dirtied room.
 
While they were cleaning the new couple couldn't stop looking at each other, grinning, casually touching. Both of them knew that there was no way they would be able to focus in their classes tomorrow as they sat together, and Kari commented on it. They laughed, and before too long they had everything cleaned up and were dressed again.
 
The two then took each other by the hand and walked out of the classroom, planning to stick together as long as possible before having to go to their respective homes.
