Fandom: Bofuri
Item: Rare candy
Type: Body Modification and Common sense Modification
Effects: One or more candies wrapped in blue foil, when eaten, grant the consumer an enhancement in various aspects of themselves, from things like intelligence, strength to physical appearance (either an improvement or development to a more "mature" stage). In the latter case, it has been observed that there is often a kind of "altered perception" among those around the consumer, preventing them from suspecting anything unusual, However, there have also been cases where this effect did not occur, either partially or completely.
Multiple candies should not be consumed in a single day; the consequences range from futanarization (though temporary and not guaranteed to occur), lactation, Higher probability of pregnancy, increased libido, increased semen production, etc... all within a 24-hour period, as these effects then disappear.
Prompt: Maple was given a bag of these candies as a gift, and that night she ate two. The next morning, Sally visited her after school, worried, only to find a more "developed" Maple who cornered her against the wall, saying she could no longer hold back before kissing her. Things escalated quickly, and they ended up having sex for the rest of the day, during which Sally was overwhelmed by her friend's newfound, superhuman stamina, and was treated like a sexual object with love and care; after all that, they officially became girlfriends.
A rare day for Kaede happened, NWO was under extended Maintenance, the new Layer got some nasty bug found last minute by QA, alongside some aftershocks of another Lawfare between two Game companies making Games made in the country hastily change certain things to stay away from it while their own Legal departments covered their bases to stop the silly madness that one legal lawfare mixed with Patent Trolling was starting.
So with homework complete and nothing else to do, it was a welcome surprise that someone decided to make his rare Visit.
"Uncle!"
"Heya, Kaede, I'm not that old yet, okay?"
While not an actual Uncle in the family, he got treated like a member still thanks to having helped them big time in the past. Even if a Foreigner, tall and handsome looking guy, the vibrant red hair, short and wild in style. Exchanging pleasantries with her mother, he had come for a quick visit, just as he had arrived, he left, not before gifting them.
"Ohhh! Thanks!"
"It's nothing, just stuff from my business that's entering sales."
Too focused with her own gift to notice the gift her mother received, Kaede marvelled at the bag with candies, the transparent plastic bag, celophane no less, let those coloured sweets shine with the light. Waving a goodbye to him, her day was made great thanks to such Visit. Back to her room, the sketchbook received a new drawing, distracted making a silly drawing of herself with an Adult body with Hourglass proportions posing in the stereotypical sexy pose to him. Sally for some reason was sitting in a chair as part of the image, she put two of those candies in her mouth, a soft, sweet Melon and peach flavors.
X-X-X-X
It was a rare occurrence for her friend to miss school, more so due to "Sickness", as her Yearly Cold had already happened. So of course, she had come to see if she was fine. Ringing the doorbell, it took a minute for the door to open.
"Risa."
"Eh... Kaede?"
At the doorway, Maple, no way her best friend would mistake her hair, face and voice. Except what she was seeing is a taller, curvier, more mature looking version of Kaede, and she is flabergasted.
"Ah, come in...."
She sounded a little lethargic, back hunching foward, like a timid introvert. Entering, no soon the door lock clicked, Risa had to talk about the Fortress in the room.
"What happened to you?"
"Eh? You don't think this as normal?"
"As if you being this... Bigger is normal."
While her friend gestured to indicate her whole body, that she gazed intensely at her chest hinted Kaede that the implication was different. An uncomfortable heat started in her groin, again.
"Finally someone noticed this! Mom didn't even think anytjing was abnormal when I woke up like this!"
Tears started escaping Kaede's eyes, letting she release it while getting some drinks for both, Risa listened in to her friend's plight. Waking up like that, her parents finding nothing unusual, and all the anxiety of the situation overwhelming her.
"It's fine, we will find an answer, and possibly a solution to this."
Patting the black haired girl's head, Sally cheered Maple up, voice soothing.
"First, we have to find the cause of this, ok?"
"Ok."
In Kaede's room, the first suspect rested on top of her desk, the Bag of candies. Hearing they were a gift of that honorary Uncle of her family already made them a prime suspect.
"I'm certain these will be the reason you ended like this... Do you have his contact info... Kaede?"
Turning to see what she was doing, she looked her way, cloudy eyes filled with a type of intent that made Sally feel uneasy, a bulge on Maple's shorts, she borrowed from her mother as nothing she had fit her anymore, it was way too big to not be that kind of thing.
"Risa.... Sorry but... I can't resist anylonger."
Dropping those shorts down, Kaede was packing a cock, with balls, the size was nothing to joke about, and those tennis ball sized nuts gurgled and pulsed with all the semen it was producing. At half mast, the penis pulsed and twitched, in desperate need of release.
"Maple! Please, keep calm... We can solve this! Just plea-"
SLAM
Doing a Kabedon, the bigger of the two trapped the other, the room filling with the smell of pheromones, gulping, Risa could only prepare herself.
X-X-X-X
How long since they started? Sally looked to her left, where the digital alarm clock, it had been four hours since the beggining, clothes spread over the room's floor, the naked bodies of the two entangled while on Kaede's bed, the wood body creaked and bent from the force of the pounding her friend was doing on top of her. Arms hugging thight, a slop kiss further draining Sally's ability to think straight.
PLAPPLAPLAPLAP
The loud noises of sex filled the room.
...
Past 8pm, Diner was about to be served, drained and exhausted of both energy and baby batter to shoot, Kaede's cock shrunk and flacid, tired, in need of rest. Resting on top of her bigger body, using her G cups as pillows, Risa, pussy leaking jizz like a fauty faucet.
"Geez, you stupid. What if today was a risky day?"
"Ah... Etooo.. Ble-kh!"
Hitting Maple's forehead with a flick of her fingers, she stopped the stupid act then and there.
"You dummy! Take responsibility!"
"Y-y-yes!"
"Then it's settled, you and I are girlfriends now."
"Sure... Eh? EHHHHHHHH!"
That Futa package went away the next day, Maple however had to live with the current body of hers, Sally sneaking a Candy of that bag for herself, calls of that Uncle ended in a digital secretary, only a year later he returned, bringing a solution to their Plight, it just enhanced the couple's nightime activities however.
Fandom: Konosuba
Item: Monster Essence Capsules
Type: Body Modification
Effects: Tiny, pill-like capsules that come in a variety of colors, each color corresponding to the monster who's essence it contains. After a pill has been ingested, it infuses the consumer with the essence of a species of monster, transforming them into that monster for roughly an hour. User still retains their intelligence, though may still experience some base instincts of the monster they become (dragons may suddenly desire any shiny objects they see, or harpies may develop nesting instincts, for example). Monster forms still somewhat resemble the consumer's original form, retaining some of their original features such as hair and eye color, even after transformation (think Ben 10 alien logic). Multiple pills may be consumed to extend the effects, and multiple pills may be consumed at once to obtain a mixture of traits. Pills may also be dissolved in liquid and consumed that way.
Prompt: (Can be set in the same continuity as the Masculinitea and Supreme Ecstasy Fireworks prompts). Darkness finds the Stall while out shopping for the party, and can't resist buying the ME Capsules to fill out her "defeated heroine ravaged by a giant monster" fantasies with Kazuma. Aqua and Megumin catch them in the middle of their fun, and after stopping them from accidently killing the monster-fied Kazuma, Darkness explains about the pills. Despite scolding them both for being perverts, the other girls can't help to get their own ideas with the pills, over the next few weeks...
Axel, starting place for about every Isekai'd adventurer, trove of trouble, and home of the party comprised of the most unique as well barely functional Party of adventurers to curse this world. And said place was just having a fair full of travelling merchants crazy or daring enough to make sales in such place. To the mentioned troublesome Party, they wouldn't enjoy the full duration of the weekend long fair, as they were leaving for a day and night long quest trip. On free time after completing the purchase of all necessary supplies, Lalatina.
"Hm, most merchants are the same old crop, clearly ready to rip axel's adventurers of their savings."
Ignoring the stalls ran by people she knew were overcharging for those quality goods, or scamming by selling mediocre crap as something far more valuable. The new faces really spoke wonders that they were not aware of the abnornalities Axel has been home to for a while already. Some sold decent gear at acceptable markup, even Paladin gear, as far Darkness could gauge the worth of those things, others had miscelaneous or gift type trinkets for sale.
"Ohhh..."
The moment her eyes met the items at a peculiar Stall, they shone with interest.
"We got things that may interest you, Adventurer."
Greeting her, a woman wearing a sleevless thight fitting shirt, leaving a generous amount of cleavage and underboob visible, her short hair, vibrant red color, had a wild style, complementing her stunning beautiful face like nothing else.
"O-o-oh yeah? What would these be perhaps?"
Moving her mind to anything other than how dazzling her face was, Darkness pointed to a random item on the stall table, a black riding crop.
"Hitting an ally of the opposite gender applies a Haste buff to both user and victim of the attack, or to the user alone if hitting an enemy of the Opposite gender. Doubled effect if the one struck is a Masochist."
"Huh? For real?"
"Yup."
Not changing her poker face, one with a smile that was anything but one of niceness, the Stall worker awaited the customer next action.
"What about this one?"
Looking at a rubbery looking bodysuit this time.
"It negates a Percentage of damage, the more aroused the wearer is, the greater the value negated."
"And it doesn't amplify it if the wearer is the opposite of aroused?"
"It just won't negate anything. To reach that zero percent value however, you really need to be irking the one equipping this."
'This is a Paradise! A mecca! I must see what they have to offer!'
Pumped up, the ridiculousness of those products made Darkness remember the incidents with that stupid tea and Aqua's Fireworks, remembering those bring a question to the Maso Paladin's mouth.
"Excuse me, but your business wouldn't be acquainted with a Handsome guy operating another stall and a travelling merchant perchance?"
"Oh, they are fellow coworkers of this humble Business, we pride that what we sell works as intended and designed for, and any mishaps are on the user end, if that's your worry."
"You swear? Under the Name of Eris?"
"I swear."
Taking the words in good faith, Lalatina looks around the wares. It was as diverse as it made her maso desires flare hotter and hotter. A Sword that creates AoE blasts by making the user get struck by a Lightning bolt of divine punishment; a Paladin armor set that was a Living tentacled suit that turned the wearer into a capable Paladin at the cost of the tentacles molesting you for as long you wore it; a Megaphone that lets the user call someone and make them do as they verbally command through said megaphone...
"By Eris! You can't keep tempting me with such nasty tools!"
Squirming and hugging herself, Darkness could barely hold back the desire to just splurge her entire savings plus some to buy all of it, then she notices it, resting by a corner of the table, a few white plastic bottles of some kind of medicine.
"Eyeing those? Daring, ain't ya?"
For once the stall worker has her voice change, her tone of amused expectation.
"And they are?"
"MEC, each Pill contains a special drug mixed with a sample of a specific Monster's essence. Once ingested, the one who consumed the capsule will temporarily gain traits and features of the given Monster, still themselves in personality and general appearance, no loss of intelligence or reason, though some base instincts of the species might affect them. Mixing and matching different essences create a Hybrid with the same traits as previously."
"What monsters we talking about?"
"Dunno, but for sure there's Troll, Ogre, Oni, Succubus and Incubus, dullahan, Elder Lich... Even Goblins and Slimes. I recall someone say an user got a jackpot of a Dragon or a Chimera."
"How much?"
Slamming her hands on the table, lucky her it was one with Reinforcement enchantments, else it would have become sawdust from how violent the impact was. The price for each bottle was surprisingly high, but she bought all three present for view. Accepting the bag with those inside, Lalatina skipped her way back to the party's home in the best mood ever.
X-X-X-X
The Quest was nothing complicated, a dungeon exploration and item retrieval task, while it was completed, Kazuma really worked to the bone, stopping Meguming several times from trying to cast an Explosion Magic, and whacking Aqua into doing her work using her OP Water powers to wash the enemies away, which were possessed armor suits made of Solid Sodium (aka the Metal that Catches fire when in contact with water), at least the water was enough that once the small horde of them got washed away into a Monster nest room, the amount of Armors immersed in water caused a Steam Explosion from sheer heat alone.
The item was in a Treasure room, trapped of course, Kazuma's luck again came in clutch, steal got that from a safe distance, and the Rolling Boulder trap met the immovable masochist called Darkness. All in all, a mostly trouble free Quest completed. The return trip could be said to be the more difficult section, what with the girls complaining about the hot weather, after going through the cold and damp dungeon halls, returning to the Scorching sun amidst a heat wave period was indeed hellish. Lucky Kazuma that this world's clothes weren't like Modern Japan ones, else the sweat from then would be turning the carriage trip into wet shirt fiesta.
X-X-X-X
"Oof, my suit is totally drenched! To the Laundry it goes."
Taking her armor and bodysuit out, Lalatina dumped the black piece of clothing onto the laundry basket for washing and joined Megumin and Aqua for a Bath, Kazuma using the bathroom closer to his own bedroom instead of the Opulent bath house section of their Mansion, now occupied by three women no less. Refreshed, clean and smelling of rose scented soap, Lalatina put on lighter clothing, a White shirt and Pale yellow shorts. The explosion afficionado party member already bunkered in the library studio, wanting to further expand her knowledge to enhance the only Spell she knows to use. And Aqua was out already to waste herself and money on booze at the Guild operated Bar.
"Better time for that is now, I suppose."
Collecting her purchase of then at her room, she prepared some tea, normal one this time, she approached Kazuma's room, tray with the tea pot, cups and dispensers for sugar and milk.
Knock knock
"Kazuma? Can I enter?"
She asks.
"Come in."
His voice answered, from the looks, he was lying on the bed. Opening the door, closing it with her hips, hands busy carrying the tray. Seeing Lalatina arriving with tea got his brain cogs moving, he smelled some outrageous request coming.
"Cut to the chase, spit it out."
"Can we fuck?"
"What's the catch?"
Seeing her blunt request for sex, he knew something was afoul, and not wanting to run circles trying to excuse what she wanted, Darkness put the tray on the large drawer by the window, then promptly prostated in front of his bed.
"I want to play some really fucked up Fantasy of mine! Please grant me this much!"
"Explain..."
It was a simple but very stupid sounding fantasy. A noble female Knight defeated by a Monster of significant larger size, humanoid, so a Troll, Ogre or Oni, and is user by her enemy like some sex toy. She presented the capsule, one half was coloured an Earthly red, which the cheat sheet provided along the purchase meant it was of Oni essence.
"Please Kazuma!"
Puppy dog eyes, and her generous bossom making a cleavage window thanks to her shirt being loose, he acquiesced. Taking the capsule and downing it with a cup of tea, three sugar cubes mixed in. The effects started in minutes.
"Whoah... These are some potent effects... Geez... Yeah, being a beefcake is not for me."
Inspecting his Onified body, tall enough that Lalatina only reached the pair of abs on his six pack bellow the belly button, his whole body screamed in muscles, a Horn protuded from his forehead, skin changed to a red with light brown tone mixed in, since he expected a surge of size, he was naked to avoid having to buy new clothes, so he and Darkness could marvel at his quite sizeable tool for the deed. A pool of drool was forming under the Maso Paladin, her mind going fullspeed into all the fantasies of being manhandled like a toy while that monster of a cock, fully erect, reshaped her entire pussy and womb to never be able to feel good by anything but that monstrous snake of a schlong.
"Eeep!"
Since she was busy imagining things, Kazuma started to give her what she wanted, with zero warning, his two hands grabbed her, lifting the far smaller Paladin was easy, both the new size and his muscular body made it like picking some random pebble by the road.
"Well, time to debut my latest toy."
Grinning, his jagged teeth making even the usually goofy Kazuma grin look menacing.
"Y-you fiend! I w-will never submit!"
"Is that so?"
With the heart shaped irises and thick line of drool she had, the phrase sounded as fake as it was.
SCHLOP
"OOOOF!"
The full length of that erect phallus speared her womb, a bulge formed in the stomach.
"I like defiant toys, makes it all the better breaking them!"
"I will make you p-pay for this... Y-you brute!"
Ignoring those poorly acted words, Kazuma started moving Lalatina uo and down the length of his shaft, like an actual Onahole.
X-X-X-X
Three hours in, three capsules downed, getting his fourth, another Oni one, Lalatina experienced Oni, Troll and Ogre sized cocks, being played like an Onahole and even the taste of Kazuma's transformed state schlong, he shoved his cockhead inside her mouth after getting tired of the lower holes. The room was a steaming sauna of sweat and the smell of sex.
"Last one, no more."
He makes it clear he is finishing with this one.
"Understood... Haahh... Haaahhh..."
Panting like a Hog, she loved every second of this play of theirs.
"Kazuma! I heard noises from your room what-"
Megumin just barged in his room, he never locked the door, more because Aqua oftenly just destroyed it if he did it. Seeing Oni Kazuma, with a Naked and clearly fucked up Lalatina, a short crash of the Mage's brains happened.
"KAZUMA! I need more money!"
And Aqua enters, reeking of alcohol, bottle of a spirit in hands. She stares at him... Or what looks like him, but is too muscular, skin colored red, and a horn on his forehead. The musk of sex in the room breaks her from the alcoholic daze.
"MONSTER!"
"GET AWAY FROM DARKNESS, YOU BASTARD!"
"AAAHHHHH WAIWAITWAITWAIT-"
A ball of Flames, growing by the second, Megumin's Explosion Magic, while Aqua starts charging a Holy Smite Water Spear spell, the poor Adventurer Luck minmaxer party leader already sees himself needing a resurrection at Eris Church, if enough of his body remains after their attack.
"STOOOOOOOOP!"
getting inbetween the two women about to strike down and destroy their house, and likely cause tons of collateral damage around the area of Axel, Lalatina, interrupts it before too late.
"He's Kazuma! We were using something I purchased!"
Given her genuine face of Panic, the two call their attack off. A brief explanation later, Megumin apologized, and Aqua, prideful she was, got firsthand experience of Kazuma's new Watermelon destroying ass cheeks, one clamp of them and the oftenly useless goddess almost got the head popped by them. Of course, the sexual play between him and Darkness ended early.
"Still, that's rather degenerate of you two to be engaging in, it's absolutely dirty and foul!"
Recovered from the ass crushing session, Aqua scolds the two. Those two girls however were already having less than pure thoughts already, about the uses of those Capsules...
X-X-X-X
"You agree with that useless Goddess in scolding me, yet here you are..."
"Sowwieeee..."
Megumin meekly speaks, as she has a Foot long of Kazuma Centaur cock filling her. Hands stuck to a breeding railing in the Mansion's stable building, courtesy of having a talisman slapped on each hand to keep her from escaping what she demanded he do with her, Centaur sex with her as a human.
...
"Again, not so though, huh? Useless Goddess!"
"GAH! I'M SOR-"
SLAP
She gets a snap on the ass, from one of his slime tendrils, Aqua turned into a Fairy, diminutive in size, and utterly powerless to pru herself off Kazuma's slime body, as he used that gelatinous body to full effect with Energy drain. Soon her mouth, pussy and Anus were being violated by more tendrills he created.
"Geez, you three are utterly insatiable!"
Groaning, he keeps at it, not one free moment in their hone where one or more of them drag him to do sex while under the effect of those Capsules.
