The Prankster's Lake Shenanigans

Class 3-E Woods

It was a sunny Saturday. White, fluffy clouds hung like cotton balls in a clear blue sky. The breeze was heavenly as it blew on the small mountain where the Assassination Classroom resided. Being a weekend, the children who made up the classroom were all enjoying their day off from both school and their assassination attempts at their teacher, Korosensei.

The three teachers were also absent from the wooden building. Karasuma was meeting with his superiors to discuss new plans to try and kill the unkillable octopus. The sexy English teacher, Irina Jelavic, was off on a shopping spree, hoping to find something to seduce Korosensei into dropping his guard so that she can finally avenge her previous humiliation. As for Korosensei, the yellow superpowered octopus was taking a break by visiting the Bahamas, working on his tan on an uninhabited island.

However, that didn't mean the mountain was completely devoid of anyone.

Inside the woods near the classroom, a certain schoolgirl was busy dipping her feet into the pool that their teacher had made for them. "Ahh…this feels so good…" Rio Nakamura smiled with pure bliss as she enjoyed the cool water on her bare feet. "You know, if Korosensei does blow up the world next March, at least I get to go out having been to a nice pool."

Her ears picked up the sound of footsteps coming up from behind her. Turning her head, the blonde teen was surprised to see a certain red-haired rebel walking into the pool area. "Karma? Odd to see you here on your day off from school. Korosensei isn't here, you know."

The punk student merely smiled at the blonde, walking up next to her right side. "Yeah but I figured coming here for some alone time might give me a few inspirations for some new pranks."

"Pranks on Nagisa or pranks on Korosensei?" asked Nakamura, eyebrow raised in curiosity.

"…Yes," replied Karma.

Nakamura laughed. "You don't ever change, do you, Karma?"

"I wouldn't be me if I did." Karma took off his socks and shoes and sat down next to Nakamura, joining her in dipping his feet into the cool water. "What about you? How come you're here all alone? The classroom isn't exactly the best place to spend your Saturday," he pointed out.

"I just wanted to enjoy some time with the pool by myself. Having some splash time with friends is fun but sometimes a girl likes to enjoy things on her own, you know?"

"Fair enough." Leaning back, Karma looked up at the sunlight peeking through the forest's canopy. "It's pretty quiet here. I'm surprised Bitch-Sensei isn't trying to do like Korosensei and work on her tan."

"I and the girls asked her that a few days ago. She said she'd lose her credibility if she started doing the gyaru look. When I asked her what she meant, she told me 'There's a difference between looking sexy and looking like a cheap fuck'. I think I get what she meant."

Karma thought about it for a few seconds, the image of their big-tittied teacher with tanned skin popped into his head. "Yeah. I think she might have a point for once. Although I doubt Okajima wouldn't mind."

"There's not a whole lot that Okajima wouldn't mind. That dude's brain is just one big volume of hentai."

The two settled into a soft silence, the sound of the creek trickling into the pool filling them both with a nice sense of serenity. Karma and Nakamura were both tempted to bring up their ideas to assassinate Korosensei but the two couldn't bring themselves to do it. Not here, in a spot that their teacher had worked hard to give them some much needed rest and fun, far away from Principal Asano's abusive ideology. No, today they would both leave the assassination for tomorrow.

Looking over at her red-haired classmate with a curious gleam in her eye. "Well, we're here and there's nobody else around. Wanna go for a swim? We don't have Korosensei to annoy us with his pointless lifeguarding," she pointed out, cocking a thumb over to the empty lifeguard seat.

Karma cocked his head to the side, giving her a smirk. "We don't have our swimsuits though."

Standing up straight, the blonde reached for her shirt. "So? Don't need them."

The boy sat there at the stony edge of the pool, his pale eyes widening as Nakamura stripped down in front of him, doing away with her shirt and pants until she was in nothing but a blue bra and a matching pair of panties. Without hesitation, the girl dove into the pool, smiling happily as the cool water embraced her.

A blush spread across Karma's face. He knew that the blonde girl was bold but today she was being bold. His eyes cautiously glanced back at the Class 3-E campus. If Korosensei were to come back early and find them, he didn't know how the octopus would exactly react but he didn't need to be the smartest boy in the class to know it would be incredibly embarrassing and humiliating for them both.

But seeing Nakamura's head poke out of the water and beckon him with a grin made him decide to risk it. 'What the hell, why not?' He stood up and whipped off his shirt, giving Nakamura some nice eye candy to ogle thanks to all the exercise Karasuma had put him through. The constant P.E. exercise had helped give him a thin, lean yet toned body. Nakamura felt her heat beat a little faster as he unbuckled his belt before unzipping his pants, stripping down to his boxers. "Heh. And here I thought you were a briefs kind of guy. Guess I lost that bet with Okuda," she lamented to herself.

"You girls always bet on what a guy's wearing underneath?" asked Karma with an eyebrow raised.

Nakamura merely smiled back at him. "Only the boys we're interested in seeing in their underwear."

Tossing his pants to the side, Karma jumped into the pool in a big cannonball, landing in the middle of with a huge splash. Treading water, the two friends laughed at each other before they started to enjoy themselves.

For the next hour the two teens played in the pool, splashing each other, trying to dunk one another, racing each other from one end of the pool to the other. For a moment, Nakamura tried to prank Karma by diving underneath him to pull down his boxers. Karma was able to stop her and got her back by swatting her butt as she tried to swim away.

Feeling they had had enough fun in the water, the two soaked teens climbed out of the pool and returned to their original spot, sitting at the stony edge of the pool to dry off. "It's a good thing none of the others were here. They'd probably ruin the moment," Nakamura noted, leaning back and smiling as a cool breeze filled the area, gently drying off her wet skin. The pair sat facing each other, only a few feet of distance between the two teens.

"Oh? I'm surprised you didn't call Nagisa over here to try and pants him to see if he's a chick or not," Karma said with a small smile. He knew the girls were always wondering if his best friend actually was a boy. Having known him for several years and understanding the circumstances regarding Nagisa's mother, Karma could have given them a solid answer but found the girls' inquiries rather amusing.

"Heh, I figured I'd save that for another day. I figure he could use a break from my teasing. I'm more interested about you, Karma."

"Why's that?'

"Well," looking over at the wet boxer-clad Karma, the blonde simply gave a slight smile. "We've kinda been partners in crime for a while. I mean, we both tease Nagisa. We've constantly put our heads together for ideas to take out Korosensei and get that bounty. Heck, we've even given that prat Asano a run for his money."

Karma would have pointed out that technically it was only her that was able to beat Asano during the first trimester's finals but he didn't want to stop her train of thought. "Yeah, we make a pretty good team." He'd thought that Okuda would have agreed to pair up with him for his schemes but the girl was more focused on her chemistry, leaving him to tag with Nakamura more than he realized.

Staring at Nakamura's soaked body, her underwear clinging to her soft skin, reminded Karma that the blonde was much more than just a classmate or fellow assassin. The girl was blossoming into a woman and her wet underwear only made that fact all the more prominent.

Nakamura saw the way Karma was looking at her. Her pale blue eyes glanced downwards and could see the effect of her sex appeal beginning to make itself known. "So…you want to us to just stay as partners in crime? Or maybe…we could step it up a notch. We're already friends…" Nakamura's foot slithered closer until the tips of her toes brushed against the bulge in his boxers. "Wanna become friends with benefits?"

Later that night, Karma would have liked to say he weighted his options; that he didn't just act on his hormones and give in to Nakamura's advances as easily as a letch like Okajima or be as weak willed as Nagisa.

But try as he might, Karma could never ignore the fact that he gave in so easily.

"I'd like that," he said with his usual smile just barely containing his awakened lust. "I'd like that a lot."

Chuckling, Nakamura reached out with her foot and grabbed the hem of Karma's wet boxers and pulled them down. Her pale blue eyes lit up when the redhead's cock stood at attention. "Looks like your GPA isn't the only thing that's best in the class."

"Heh, have you been spying on the guys?"

Nakamura put a finger to her lips. "My secret. Let's just say I've been thinking about this guy for a while. I guess I should say hello."

Karma expected the sexy blonde girl to start to pleasure him with her hands or her mouth. Instead, he was pleasantly surprised when her feet wrapped around his shaft, gently getting him off with her soft feet. He leaned back as he enjoyed the feel of her feet, watching them move up and down. "Ahhh…" He never thought he'd be enjoying a footjob. 'Looks like I'm going down the path of becoming like Okajima…' he thought to himself.

Giggling from the look on Karma's face, Nakamura looked down and saw Karma's cock leaking pre-cum. "Hitting the books a little too much lately? This big guy looks like he's already about to blow," she teased, her toes rubbing the thick tip of his cock. Having Karma in her grasp awakened Nakamura's inner Dom. "You like that, don't you? You want to blow your load. Come on…" Putting her arms behind her back to show Karma her clean, shaved armpits. She didn't know if Karma was into that but like Irina taught her: "If you've got it, flaunt it."

The summer sun on Karma's mostly-naked body felt like it was going to sear through the young man as his cock twitched in Nakamura's foot prison. Seeing Nakamura's armpits made a few dirty ideas pop into his head. Part of him wanted to get up and pleasure himself with her armpits like a dirty pervert but the feet on his cock kept him still. A bead of sweat ran down his bare chest while he struggled and failed to contain himself. Unfortunately, Nakamura's comment was a little on the nose. Karma had been so caught up with both his grades and attempting to assassinate Korosensei that he'd neglected to give himself proper stress relief. As shameful as it was to blow his load from only a little footjob, the pressure in his loins was too much for one young assassin to bear. 'Getting off on a footjob while staring at a girl's pits. Yep. I'm definitely turning into Okajima…'

"Ngh! Ah!" Karma's amber eyes squeezed shut as the pleasure rose though his shaft. "Damn! I'm coming!" he grunted. His body tensed and his head rolled backwards. Nakamura's eyes widened as the cock nestled between her feet erupted with a white geyser of cum. String after string of white, sticky spunk sprayed from Karma's tip, covering the blonde's feet. Having never seen a man's orgasm up close, Nakamura stared in shock and a little awe.

Taking her feet away from Karma's cock, Nakamura dipped them into the pool to wash them off. "Wow, Karma. You were pretty pent up. At least you got it out of your…system…" Nakamura's blue eyes widened when she saw that despite blasting out so much cum, the redhead assassin was still hard as a rock, his impressive erection standing proud and pointing at her hot body. "Damn!"

Smiling, Karma stroked himself and stared intently at Nakamura's panties. Her underwear had dried off but he noticed a wet spot that couldn't be blamed from her swim.

"Up for more friends with benefits stuff?"

"You know it."

Nakamura knew that the longer they stayed in the pool, the longer they risk getting caught by Korosensei; sure, the superpowered octopus was busy working on his tan but if he had to return to the classroom to get a lunch he forgot to bring with him or grab more sunscreen then their goose was cooked.

Still, Nakamura felt hornier than she'd ever felt in her life. And having the handsome, well-endowed Karma all to herself in a beautiful pool where nobody could bother them was too good to pass up. Consequences be damned, she was going to get fucked.

Standing up, the blonde assassin reached behind her and unclipped her damp bra. Karma's cock throbbed and his heart started to beat faster upon seeing Nakamura's bare chest. The blonde easily had the biggest pair of breasts in the Assassination Classroom, her firm D-cup tits bouncing free. Nakamura's pink nipples were already hard from the cold water. Her panties were the next to go, sliding them down her slender legs and showing off her full nudity to the boy.

Nakamura's slim legs went up to her soft thighs and her pink, puffy womanhood. A small, trimmed patch of blonde hair crowned her pussy. When she turned around to show her soft, plump butt, Karma had half a mind to give it a nice spanking.

Now in her birthday suit, Nakamura jumped back into the pool. It felt so different to go skinny dipping but it felt so good. "Mmmmh." She looked up at Karma and grinned. "Well? Aren't you going to join me?"

Karma ditched his boxers as fast as he could. The brain in his head had shut completely off and all rational had gone out the window. Joining Nakamura in the buff, Karma gladly jumped back into the pool, wading over to her in the shallows so they were both standing up.

Nakamura's slim arms wrapped around Karma's shoulders as she leaned forward, her breasts pushing against his slim chest. Karma's hands dipped underwater to grab her soft ass before their lips met, the two teens giving each other their first kiss. Remembering all the kissing lessons that their sexy English teacher had given them, the pair did their best to try and dominate each other's lips. Nakamura opened her mouth, allowing Karma to slip his tongue in. A jolt of pleasure shot through his spine as their tongues entwined, his cock pushing against her smooth belly while he held her tightly in his arms.

Readying himself to become a man, Karma gripped Nakamura's soft ass and lifting her up. Understanding what Karma had in mind, the blonde wrapped her legs around him and mentally prepared herself to be deflowered. Breaking the kiss, Karma smiled into Nakamura's eyes. "Ready?'

"Ready."

Keeping a tight grip on Nakamura's peachy ass, Karma slowly lowered her down onto his cock. Nakamura's pink petals gave little resistance, the cool water helping to ease him into her tight hole.

Nakamura told herself she was prepared but when Karma's cock pushed into her pussy but she still stiffened in his arms when her maidenhood was speared. Thanks to all the vigorous physical activity, she had no barrier to tear, but that didn't mean she was tight as hell. "Nghhhh!" The naked blonde's face twisted as her walls stretched around her first cock, her nails instinctively digging into Karma's shoulders as she struggled to endure the slight pain of being deflowered. Her eyes squeezed shut and tears threatened to leak out.

Karma thought he was ready for just about anything after being in Korosensei's class but he was ill prepared for the tight warmth of a woman's most private place. Holding her in his arms, the redhead clutched her tightly while basking in the rapture of it all. "You okay?" he asked when he saw the pained look on his face.

It took a few seconds for Nakamura to answer while she struggled to adjust to having Karma inside her, the naked blonde's breathing heavy and haggard. Finally, Nakamura opened her eyes and gave the redhead a nod. "Yeah. Go ahead and move."

Nodding in turn, Karma shifted his hips and slid out of Nakamura's pussy, the tight suction of her walls trying to pull him back in. Breathing heavily, Karma pushed back in, making sure the grip on Nakamura's ass was secure as he began to move, his cock pumping in and out of the girl slowly. The tight, warm walls squeezed him with every move he make, as if Nakamura's body was craving for him to blow his load already. The erotic sensation was amplified by the water that surrounded the two teens.

The quiet calm in the pool area was shattered by the twin pairs of moans that filled the mountainside. Once Karma found his stride, he turned the tranquil pool into Splash Mountain. "Nakamura…fuck, this feels great!" He squeezed Nakamura's ass, his fingers dangerously getting close to her backdoor.

Clinging to her new lover, the naked blonde cried out in absolute ecstasy. The pain of being deflowered had melted away. In its place was pleasure unlike anything she'd experienced in her life. Her breasts pushed against Karma's hard chest, the girl's tits jiggling with every thrust. "Harder! Ah! Harder! Oh! Harder!"

Spurred on by his lover's pleas, Karma pulled out until only the head of his cock remained nestled inside Nakamura's cunt before thrusting into her with all his strength. The water around them sloshed and splashed around them like a ship caught in a storm. "Fuck! So…so tight! You feel so good!"

"Ah! That's…that's only because you're so big and hard!" Nakamura cupped Karma's face, looking him deep into his pale eyes, pressing their foreheads together. "Fuck me! Ah! Make me come!" Crashing their lips together, Nakamura moaned into his mouth, her tongue exploring every inch of him while she squeezed her pussy around him. "MMMMMH!" Her pussy pulled him in deeper, the blonde feeling him grind against her womb.

For the first time in her life, Nakamura felt a woman's true bliss. Moaning into Karma's lips, she came around his cock, squeezing his shaft oh-so tightly while clinging to him like a life preserver. Despite his tough, devil may care attitude, Karma folded easily to the tightness of a woman, moaning back into Nakamura's lips as he came. All thoughts of any potential consequences went out the window. His eyes closed while he emptied his balls into her pussy, pumping her full of white, hot cum.

Karma's hips finally came to a stop. Nakamura pulled away from the kiss, panting for breath while a sticky string of saliva still connected their lips. "Holy fuck…that…that was…wow…" Despite being the best in class in English, her words failed her to describe what she was feeling.

"Yeah." A bead of sweat ran down Karma's blushing face. Despite the coolness of the water, his body felt as hot as a raging inferno. "I know what you mean."

Carrying her over to the edge of the pool, Karma pulled out of Nakamura and set her down on the stone edge. However, looking down beneath the pool, the blonde was shocked to see that Karma was still locked and loaded. "You're still hard? Just how pent up were you?"

"More than you'd think."

"Well, it wouldn't be good if I left you pent up." Sliding back into the pool, Nakamura turned around and leaned against the edge, pointing her ass at Karma. "Well?"

The redhead didn't need any more invitation. Walking up behind her, Karma dipped his hands underneath the water to grip Nakamura's curvy waist. It didn't take long before he slid his little sword back into its new sheath. The horny blonde bit down on her lip as her womanhood was filled once more, that pleasurably full feeling returning to her.

All thoughts of his grades and the assassination of Korosensei melted from Karma's mind. The only thing that mattered in this moment was the hot blonde and her tight pussy. Water once again began to slosh around them. Unlike before where he had to concern himself with her added weight from picking her up, here he was allowed to simply go to town on Nakamura's cunt.

Moans began to spill from the teen blonde's lips. Her ass jiggled with every smack from Karma's hips. Her nails dug scratched the ground beneath her. Nakamura knew that to fuck her fellow classmate here in the classroom pool was so wrong. But if something that felt this good was wrong, she didn't want to be right. "Ah! Karma! Fuck me! Fuck me!"

Letting go of her waist, Karma reached around Nakamura to cup her bouncing breasts. Pressing himself against her bare back, the redhead let his hips move on their own while enjoying himself with his friend's tits, feeling how soft yet firm her boobs were. "Fuck! Hahh!" he grunted into her ear.

The water around their hips amplified their pleasure. Already Karma's cock churned the cum he'd shot into her. Turning her head, Nakamura shared another sloppy kiss with her lover, her hips starting to move with a mind of their own and buck into Karma's thrusts, her entire body shaking in his arms.

One of Karma's deft hands let go of her soft breast, snaking down the front of her naked body until it reached between her legs. Tears of pleasure threatened to spill from the girl's blue eyes when she felt his fingers find her clit, her precious bundle of nerves being rubbed vigorously. "Fuck! Fuck! Ah! Oh god! Karma! You're…oh god!" Her arms wobbled as she struggled to remain upright. Ecstasy coursed through every vein in her body and her mind began to go numb. The pleasure in her loins began to blossom until she felt that blissful sensation from head to toe. "I'm coming!"

Nakamura's scream of pleasure echoed throughout the forest. Had any of their teachers been present, they would certainly have been caught. Holding her tightly, Karma felt Nakamura's tight hole grow tighter, squeezing his cock in another vice that refused to let go of him. The tightness pushed the boy over the edge, making his eyes squeeze shut while he buried his face in Nakamura's blonde hair, his thin arms wrapping around her tightly. Nakamura let out a silent scream when she felt her new lover come inside her, filling her up with even more cum.

Feeling Nakamura go limp in his arms, Karma clutched her tightly to keep her from falling forward. The tranquil silence of the forest pool returned as the two tired teens rode out their highs. Pulling out of Nakamura, Karma picked her up and carried her out of the pool. Water dripped down their naked bodies while he walked over to the pool chairs, setting her down gently on one before going to fetch their clothes.

"Wow, you truly are number one at everything," said Nakamura, the warm summer breeze drying off her naked body.

Sitting down on the edge of the chair, Karma smiled down at her. "Well, you were certainly something else."

"Aww! Aren't you the smooth talker?" giggled the blonde. Feeling the cum trickle down her legs, Nakamura made a mental note to steal some of her mother's birth control pills. She didn't want her future ruined by the sudden prospect of motherhood nor did she want to explain to both her parents and Korosensei just when and where the babymaking happened.

It took no time at all for the two's bodies to dry off. Even their underwear was only mildly damp now despite the soak. "So…you want to do this again sometime? We are Friends with Benefits now, after all."

Sitting up, Nakamura kissed Karma's cheek. "Hell yeah! I think this is the start of something great. You know…" Putting her hand on the redhead's knee, Nakamura leaned close and grinned. "My parents are going to be out of town tomorrow. Want to come over? We can go over our homework, go over a few assassination plans…and pick up where we left off?"

Smiling in turn, Karma kissed her back. "I don't think I could think of anywhere better to spend an afternoon."

"Great. Now let's get dressed and get gone before Korosensei comes back and kills us!"

Realizing how late it was getting and their superpowered teacher could be back any minute, the teens scrambled to put their clothes on and hurried away from the pool, both of them laughing and smiling happily the entire way down…

The End
