Chapter

A disembodied voice seemed to float through Shouta Magatsuchi's dreams. He was hovering in a great blue void, and below him, two golden discs, intricately carved with runes, were gleaming.

"On these are written the ancient spells," the voice said - one he couldn't recognize. His small, young body floated down toward them, seemingly propelled by his will, and as he approached, the young boy saw that he could interpret the runes as the language of mages, passed down for generations. His expressive blue eyes went wide, he scanned the surface desperately, trying to commit the runes and sigils to memory. They were written strangely, entwining themselves in concentric circles that seemed to lead toward the center of each auric disc.

"This spell… if I can perform it… I'll finally be a full-fledged mage!" he said, and reached out to touch the surface of the discs, which were larger than his body by orders of magnitude. Amazingly, with a metallic creak, the discs seemed to bulge outward to meet his hand, turning from flat circles to a pair of hemispheres. Now, on closer inspection, running his small fingers over the indentations, he saw that the runes were a sort of hieroglyphs, strangely familiar. South American, perhaps. 

"These spells will help you, Shouta-kun," the voice repeated… but now it too, sounded different. More feminine, filled with a sort of matronly airheadedness. "Touch them as much as you like!" Shouta recoiled as the two golden hemispheres expanded, growing bulbous, and trapped his body between them. He expected to feel the crushing weight of two metal surfaces, but to his surprise, the tactile sensation was soft and warm, as if the rune-carved discs were filled with fat!

He struggled to get away as the discs enveloped him. "These will make you a full-fledged mage, Shouta-kun!" the voice said again, and it now sounded very unlike the disembodied rumble it had once been. It was a female voice he'd come to know very well over the past months-

Shouta's eyes shot open, and he found he was staring directly into the face of Lucoa, the voluptuous female he'd mistakenly summoned a while back, and was now living at his house without permission. Her absolutely massive breasts were rubbing all over his chest, and her striking eyes - one green with strange designs in the iris, one with a black iris and a yellow pupil - were looking down at him softly and with indulgent affection.

"Ahh!" Shouta cried out, and wiggled his arms and legs like an overturned turtle, struggling under the weight of Lucoa's boobs. Lucoa's name was short of Quetzalcoatl, and she claimed to be a former goddess who had brought agriculture and civilization to the world, but Shouta was sure she was a minor demon or a succubus. His summoning spell had been a demon-summoning spell, after all. And this display of affection (and boob-rubbing) was, to the 11-year-old boy, further proof of Lucoa's secret allegiance to the dark arts.

He scrambled out of bed and pointed an accusing finger. "Now you're only proving you're a succubus!" he wailed, eyes squinted shut and small fists balled.

Lucoa looked honestly confused, an expression that had become her trademark. As an ancient being summoned to earth, she mostly had no idea about normal human behavior in the modern world. This included things like clothing, which she didn't like wearing, and the appropriateness of flaunting her huge breasts and hourglass figure in front of a young boy. "I just thought if you become more mature in other ways , it would help you become a full-fledged mage!" she explained, smiling sweetly. She was wearing a black halter-top from which her massive breasts seemed on the verge of escaping, a pair of high-cut denim shorts, and the trademark cap from which her blunt horns sprouted upward in tight curves.

"I don't need that sort of help!" Shouta objected, crossing his arms. 

Lucoa pointed a finger toward him. "But don't you like it quite a bit?" she asked, smiling her usual I'm-not-doing-anything-wrong smile. "Your chin-chin is poking up!" 

Shouta's naturally-wide eyes went even wider as he looked down at his own crotch. His pinstripe pajama bottoms were indeed showing the presence of a jaunty erection, tenting the crotch. Nothing too significant - he was only eleven, after all - but certainly proof of his body's interest, if not his mind's. He yelped and quickly moved to cover the offending protrusion, blushing totally red. "It's because you're trying to corrupt me, demon!" he cried, then stumbled out of the room without lifting his hands, leaving Lucoa sitting on his bed and swinging her legs, her expression quizzical.

"I blessed lots of people with fertility, you know!" she called after him, cheerily. "I could do that for you too, Shouta-kun!"

The only response was the boy's retreating footsteps.

Later that evening, Shouta found himself rummaging through his father's things. He was part of a family of mages, after all, and though his parents were careful about keeping all magical things hidden and maintaining appearances as a normal family, he knew where certain manuscripts and instructions were kept. He had used these, in various lessons, to teach himself spells for Sleep, Presence Concealment, and Summoning. What he didn't know, and very much wanted to learn, was how to dispel a succubus once summoned! 

Looking cute as ever with his pointy-wizard hat and brown cape overtop of his usual clothing, Shouta brushed his long hair from his face as he rifled the drawers in his father's desk. A lot of the papers were simply mundane accounting records, it seemed. "Come on," he muttered. "I know it's here!" Of course, his father wouldn't keep a magical book in plain sight, but as he picked up an old ledger that was suspiciously thick, he thought he had a winner on his hands. A simple illusion spell was in place, and by dispelling it, Shouta changed "Receipts, 2014" into "Lesser-Known Spells Of Demon Summoning".

"Aha!" he cried, triumphantly. He kept his ears open for Lucoa as he pulled the book out and studied the rune-inscribed cover. She was always wandering around when his parents weren't home, and he didn't want to get discovered. That would foil his whole plan. His small fingers moved quickly as he flipped through the pages.

Summoning Lesser Demons.

Mephit Empowerment.

The Demonic Planes And Summoning Substances Of Note.

"Come on, come on," he muttered. None of these spells or instructions seemed to directly address his problem - a succubus who had arrived and was overstaying her big-boobed, airheaded welcome! Then, he flipped another page and his eyes fixated on the title.

Manifesting The Succubus-Defeating Spear.

"Yes!" he said, his enthusiasm coming out in a whisper. This sounded like exactly what he was looking for. A spear sounded like a weapon, of course, and he wasn't exactly the fighting type… but empowered objects like these were known to render any difference in size and fighting ability moot. He imagined he would brandish it in Lucoa's direction, and she would finally agree to leave his house. He didn't want to hurt her… he only wanted to be free from her succubus' grasp, and not to be haunted by huge boobs and naked, lewd flesh every day!

He scanned the runes. The spell seemed simple enough, though it was a bit different from the others he had learned, and several of the incantations and hand movements were unfamiliar to him. He only needed to make the proper preparations, which included candles, and drawing circular runes on the ground, the easy work of ten minutes.

Once all was prepared and he was surrounded by a circle of candles, Shouta put the book down on the ground in front of him atop the arcane rune he'd drawn with powdered iron (taken from his father's alchemical supplies), sank to a kneeling position and extended his hands, palms outward - taking up the traditional stance to focus magical energies.

Closing his eyes and concentrating, he spoke the words of power and did the hand movements as instructed. Instantly, he felt the energies coalescing into a locus, and couldn't help but smile. He had expected it might take a few tries, but it seemed to be working perfectly. Even with his eyes closed, he could tell that the Succubus-Defeating Spear was manifesting directly in front of him!

He opened his eyes with excitement, expecting to see a magic weapon, already imagining himself brandishing it, chasing Lucoa, and expelling her from his house. His other attempts to dispel her, including serving bitter drinks (it turned out she liked them and he was the one who didn't), hadn't worked. But he had a good feeling about this one.

Unfortunately, the first thing he saw wasn't a 'spear' at all, not in the traditional sense. Instead, there was nothing in the circle… and it was partially blocked from view by something long, blushing pink, and thick. Something protruding from his own body! 

"Ahhhhhhhhh!" he wailed, and batted at it with his hands. It bobbed and bounced, thoroughly attached to his body. The small penis that Lucoa had pointed out earlier that day had been totally replaced by… by…

Shouta put his hands on it, feeling it, not believing it was real. It was huge. As big as his arm! It no longer seemed to match his small, thin, cute elementary schooler body! Suddenly, the meaning of "Succubus-Defeating Spear" became clear to him - a meaning just as lewd as Lucoa's constant, alarming flirtations. He blushed deep, crimson red as he realized that he was the owner of a huge, hard, smooth penis! 

He pressed down on it with two small hands but it wouldn't sink - it only jutted straight out from his hairless crotch in a gentle upward curve, returning instantly to position even if he tried to force it. His pants had literally come undone, the button snapped at the waist by the arrival of the summoned phallus… and that wasn't all! His balls, big and smooth and heavy, were hanging out too! He could feel the weight of them!

No wonder his father had kept the book hidden! This was the sort of spell that no self-respecting mage would ever cast! Shouta was still looking down at his new organ like someone who had just discovered the growth of a third arm (and it was almost big enough to count as one). He tried to wrap two hands around it and could barely touch his fingers together. He felt an almost living , throbbing virility coming from it - and even the gentle touch of his fingers made it quiver with feelings of arousal that were unfamiliar, and kin to the very same tinglings that Lucoa had seemingly made it her mission to bring out of him!

"No, no, no!" he peeped, moving to grab the Lesser-Known Spells of Demon Summoning book. There had to be a remedy inside - most spells, he knew, had a reverse-version that could be used to dispel the effects. His finger trailed down the page to a note in the lining, handwritten… and he blew out a nervous, frustrated burst of air.

This spell can only be removed once the spear has been satisfied and the succubus defeated.

"What!?" he blurted, realizing what that probably meant. In order to dispel Lucoa from his house, he'd have to… have to…

"Shouuuuuta-kuuuun!" a cheery voice echoed, from the ground floor. It was Lucoa. "I can sense magic! You're casting spells, aren't you?"

"Ah!" he yelled out, and quickly moved to hide the book, the candles, and rub out the circle of iron. He could hear her footsteps on the stairs already. Looking this way and that, Shouta found hiding places for all of his magical paraphernalia, and then stripped off his cloak and mage hat, stuffing them behind his father's desk. It was then that he realized the biggest and most unhidable thing in the room, his massive penis, was still in view!

He burst out of the office before Lucoa turned into the upstairs hallway, and went to his room, shutting the door behind him and diving under the covers, turning sideways so that his newly-enhanced penis wouldn't form a gigantic tent. Still, Shouta was certain that it would do no good, in the long run. Lucoa was relentlessly nosy and was always trying to interact with him more in order to 'build trust' - including attempts to bathe together that had sent him running naked out of his own bathtub as she stripped down. So it was absolutely no surprise when the door slid open and she poked her head in.

"Shouuuta-kun!" she teased, her voice full of merriment as usual. "Why are you playing hide and seek? I just sensed a magic spell!" 

"G-go away!" Shouta said, unable to hide his nervousness. His young face was expressive to a fault, with huge blue eyes that were windows into his emotions whether he wanted to broadcast them or not. "I'm sleeping!"

But of course, Lucoa didn't go away, and traipsed into the room in her tank top, jean shorts and runners, sitting down on his bed in a way that caused every bit of her flesh to bounce - her boobs most of all. Shouta bit his lower lip and let a boiling-teapot gasp of breath escape his mouth. He was getting funny feelings in his new penis - far stronger than what he'd felt before. Still, he stayed facing the wall and kept the sheets in place.

"Ooh, I could take a nap with you as well!" Lucoa said, and pulled her shapely, pale legs up onto the bed, laying on her side and taking hold of Shouta from behind. "It's quite cozy with two, don't you think?" Her voluptuous body was much larger than his cutely thin one, seeming to envelop him, and pressing warmly into the back of his head with those big, pillowy boobs that had sent him running on so many occasions.

Then, her hands wrapped around his waist and Shouta flailed his arms, crying out. The fingers that would have interlocked near his navel were prevented from doing so by the presence of a big, long, throbbing, and unexpected penis… that Lucoa eagerly took hold of and started to feel up and down, like a blindfolded woman trying to decipher the object in her hands by pure touch!

It was too much to bear. Shouta's flailing threw off the covers, leaving him on his back with his huge cock sticking nearly straight up, rising in front of Lucoa with monumental phallic size! His body was so small, and the cock so big, it almost appeared to be the size of his leg. Lucoa's mouth dropped open and she stared for a moment, looking at Shouta's pipe as it swayed in mid-air and seemed to pulse with virility in spite of the petite size of its young owner!

"Ara ara!" she exclaimed, clapping her hands to her cheeks. "I knew you were casting a spell - but I never knew it would be this type! You're a bit of a pervert, aren't you, Shouta!"

"It's supposed to be a weapon against a succubus like you!" Shouta gasped, squinting his eyes shut with frustration and pulling up the covers to his waist - but it was no use. Then, he gasped as Lucoa reached out to cup his balls.

"Look at this size!" Lucoa went on, putting a palm under one of his testicles and feeling the weight and volume. They were pink, totally hairless, and big enough to overflow her whole hand. "You must have done a good job with this spell!" She fanned herself, seeming to swoon. "This reminds me of my old days when I brought the secrets of fertility to civilization!" She nibbled her lip speculatively and Shouta watched her, noticing her obvious interest and distraction… and noted a rather aggressive feeling that was building inside him, no doubt caused by the spell itself.

"This only proves you're a succubus!" he cried. "Since you're so interested in it!" It was clear to him now that the intent of the spell was to empower a mage with the sex ability to beat a succubus at her own game! This wasn't exactly how he'd planned for the spell to work - and quite inconvenient, considering his lack of experience - but he had to see it through, no matter how embarrassing it was.

"I'll make you feel really good," Lucoa purred, and then crossed her arms and grabbed her tank-top, hoisting it over her head to reveal her absolutely massive tits. Her funbags had been a source of constant embarrassment for Shouta since her arrival, and now he was getting his most unobstructed and lengthy view yet. They were heavy, hanging spheres of pale, pleasing skin, with large pink nipples, each one easily larger than his head.

Lifting a leg over to straddle him, Lucoa leaned forward and let his penis plap into the furrow between her tits, then pressed then together with her elbows, creating an amazingly warm channel. Shouta cried out in pleasure and his toes twitched and curled.

"Look, Shouta-kun!" Lucoa said, brightly. "It's so long, it goes all the way through my boobs and pokes out near my mouth! You must be a full-fledged mage now, conjuring such a big cock!" She was speaking to him through and around the bulbous head of his dick, which was the pinkest part of the whole works and shaped like a bell. "It's very different from the cute, tiny chin-chin you had before!" He could feel her hot breath blowing on the underside of his glans, and it grew more intense as she pushed her face closer, striking heterochromatic eyes fixated on his pipe as she rubbed her tits up and down the shaft. "I'll give it a kiss!"

"Nooonnngh!" Shouta wailed, and pressed his head back into his pillow as Lucoa's soft lips pressed against the tip of his cock and warmly suctioned there with a subtle kissing noise. His small hands gripped the sheets, and he felt a sense of pleasure running through his flesh that was totally unfamiliar! As usual, his plans to put Lucoa off her guard had failed miserably, a repeat of serving her coffee. In spite of the spell, he was the one who was embarrassed and in retreat, not her!

Shouta blew out a helpless breath as he felt Lucoa's tongue press and wiggle against his piss-slit. "You're leaking a lot of hot stuff," she cooed, continuing her milking motions with the intense squeeze of her tits. She had them wrapped around his shaft to completely, the nipples were almost touching, and the motion was making a lewd, fleshy noise. Occasionally, the underside of her boobs would bounce against her soft midsection with a plap . She sealed her mouth around Shouta's cocktip and sucked deeply, making an exaggerated noise, like someone slurping ramen.

SLRRRRRRRRRRP!

Shouta's toes curled even more and his extremities were board-stiff against the sheets. When Lucoa finally withdrew her mouth, a drizzling strand of pre-cum connected her mouth to the knob, and she took a satisfying swallow. "What's with this amount?" she purred. "It's as if Shouta-kun is trying to get my mouth pregnant! And it's thick and gooey, even though it's just your pre-cum!" She nuzzled her face against his cock, seeming to admire the size of it. "Your cock is huge and lewd, Shouta-kun… but don't worry, I like that!"

"Of course you'd like that!" Shouta objected. "You're a demon, just like I thought! A succubus likes all sorts of lewd and embarrassing things! That's why you keep trying to get in the bath with me!"

Lucoa blinked with a blank expression and looked down at him. "Alright, you caught me!" she said, putting a hand behind her head sheepishly. "I'm actually a succubus! I can only be dispelled by someone who has enough sexual power!" She blushed deeply. 

Shouta pointed an accusing finger, becoming more animated, and asserting himself for the first time during their encounter. Even his huge penis was forgotten as he sat up, causing it to aim downward and jut out parallel to the mattress. "I knew it!" he cried. "And this story about being a goddess, was all just you trying to fool me, wasn't it?"

Lucoa, hiding a smile, bent forward in an apologetic dogeza position. "Yes! I apologize for my falsehoods! It's all because I'm a succubus who really likes cute young boys!" As she leaned forward, her face and the brim of her hat were pressed right against Shouta's dick, but far from being nervous, the validation the boy was receiving, combined with the spell, had him acting confident for the first time ever. He crossed his arms over his narrow chest.

"Then… I summoned you, so you have to obey!" he announced. "And… when I'm done with you… you'll be defeated, and go back to where you came from!"

"Oh no!" Lucoa moaned. "If you make me do lots of lewd things with your huge penis… my womb will take the shape of your cock, and I'll become your woman! A succubus who loses to a human dick is a disgrace among her kind! I'll have no choice but to return to the underworld!" She bowed even more deeply, arching her back and making her huge boobs rub between his legs, in a hammy act of performed apology.

Shouta's eyes narrowed. Was Lucoa acting a bit suspicious? He couldn't quite put his finger on it, but her speech was like something stereotypical from a hentai manga. Nonetheless, he realized that he only had the 'Succubus-Defeating Spear' for a limited time, and he would have to beat the demoness at her own game if he was going to dispel her from his house. But… how to go about it?

He tried to think of lewd and embarrassing things that would assert his dominance, in the same way she had so often turned him blushing red with her flirtations. "Maid play!" he blurted. "You should… wear a lewd maid costume… and be my servant!"

Lucoa blinked. "You mean - like Tohru is for Kobayashi?" she asked, putting a finger to her chin.

"No!" Shouta announced. "You'll be a lewd maid! With the costume and everything! And you'll do whatever I want, no matter how embarrassing it is!"

"Oh, good-" Lucoa announced, then coughed into her hand. "Ah! I mean… oh no! You're such a cruel master!" She continued to bow and scrape. 

"Make yourself a maid costume, right away!" Shouta ordered, and Lucoa sprang off the bed and extended one finger into the air, as if in deep concentration. It was only seconds later that she transformed from topless with denim shorts to a much more sexualized ensemble, including a bustier with her massive jugs pouring over the top, a black lace choker, a frilly tiara, a ruffled skirt so short that it could barely be called such - not even extending over the twin, round curves of her buttocks - and fishnet stockings with black heels. It was precisely the sort of attire one might expect from an adult-themed maid cafe, and Shouta took Lucoa's ability to quickly change as further proof of her succubus status.

"My name is Lucoa!" she announced, bowing. "I'll be taking care of you today, Master!"

Shouta shifted to the edge of his bed and let his legs dangle over the side. His penis, still protruding mightly over the top of his half-removed pants, was standing up at a forty-five degree angle, and he kicked his bottoms off the rest of the way. He knew that now was the time to 'subdue' Lucoa… but being eleven years old and rather shy, he only had a vague idea of how. It had to be something that would really break her spirits!

"C-crawl over here and lick my feet!" he ordered, crossing his arms and trying to sound confident. "T-that's your job from now on!" 

"Ooh, yes Master!" Lucoa purred, and she started to crawl forward suggestively, wiggling her hips as she approached the edge of the bed. Shouta, who had expected a bit more resistance, couldn't help but feel increasingly nervous as he watched her boobs sway (nearly scraping the floor) and her butt bounce from side to side. And upon arrival, sure enough, Lucoa submissively started to lick Shouta's small, cute feet, up and down his calm muscles, and between his toes. "Your feet are so cute, Shouta-kun!" she cooed. "Small and shapely, like a girl's!" She didn't hesitate to slide her tongue between his toes, obediently and sexually cleaning even the lowest part of his body, though she was an adult and he an elementary-schooler. "If you wore a maid outfit too, you, me, and Kobayashi could have a whole maid cafe!"

"S-shut up!" he yelped, squinting his eyes shut. Once again, his plan seemed to have backfired. He had planned to embarrass and discomfort her, but Lucoa seemed to be actually enjoying what she was doing, while he was the one who was embarrassed. Why did that always seem to happen? His frustration boiled over and he leaned forward and took hold of Lucoa's horns, which made a convenient pair of handlebars. 

"Ooh, Master!" she moaned. "You're not usually this assertive!"

"Stop liking everything that I do!" Shouta cried, and pressed his feet into her face as he held her fast. "I'm supposed to be defeating you!" He wracked his brain for some humiliating things for Lucoa to do, mostly coming up empty. "F-from now on… you have to clean my body with your tongue, every day!" he announced.

"Ahhhhh!" Lucoa moaned, her body trembling. She seemed to be in distress, which was a good sign that Shouta was on the right track. "Having to clean the body of such a young boy… that's so degrading!" she confirmed. "I bet you'll make me lick your balls and penis clean as well!"

Shouta blushed deep red. " You're the pervert who-" he started, then his voice caught in his mouth as he reminded himself that he wasn't the one who was supposed to be embarrassed. "I mean… yeah!" he finished. "You'll have to do that, each day. So… get started!"

Mustering all the lewdness his innocent, angelic countenance could manage, Shouta pulled Lucoa's face into his balls, feeling a satisfying warmth as her breath sprayed all over his nuts. He kept a firm grip on her horns as she went to work, lathering his fat, smooth testicles up with spit, and digging her agile tongue into the furrow between.

"Master Shouta's balls are so big…" Lucoa purred, breathy with the effort of slurping and licking. Her back was arched, and Shouta had taken up a leaning-back, legs spread position on the edge of the bed, holding her horns to keep himself upright. "I bet they're absolutely filled with thick, gooey young boy semen! Even though you're just a kid, I just know it's as thick as jelly!" She planted a deep kiss on one testicle, venerating it, suctioning it with a lewd blowjob face. "Mmm, one shot from these babies and I'd be pregnant for sure!"

Shouta found that he was enjoying himself in a very lewd way that made him feel a bit guilty. The sensation of being serviced by a busty older female (succubus or not) was amazing, now that he was actually allowing it to happen instead of running away. "T-that's it, slave!" he hissed, holding Lucoa's horns in a death grip. "Keep doing that, it's all you're good for!"

"Ah!" Lucoa gasped, nuzzling her face into his sack. "Master Shouta knows how to put a woman in her place! I bet you'll also tell me I'm a stupid whore, and that I love it when balls are in my face!"

Shouta raised an eyebrow. "Uh… yeah, I-"

"-and slap me around, because I'm a nasty whore who loves to fuck young boys with this busty body of mine!" Lucoa continued, in between kisses planted on his balls. She began to work her way up his inner thighs, then to his shaft, licking straight up his fat, swollen piss-pipe. "Nnngh… this huge, protruding cum tunnel is so indecent!" she added. "You must blast ropes like a horse!"

Shouta was moaning at her attentions, trying to maintain control of the situation. "Yeah, I… I mean, you're a whore who always talks about lewd things, and, I bet you want to-"

"-shove my tongue up your cute, young ass!" Lucoa finished, and she leaned forward as far as she could while lifting Shouta's ballsack to reveal his pink, as-yet-untouched anus. As with the rest of his body, it had a rather effeminate and inviting quality. Shouta blew an inarticulate breath out of his mouth and collapsed back onto the sheets as Lucoa lifted his legs high, spread them, and slid what felt like four inches of tongue up into his hot, moist bowels!

"Mmm…" she purred, licking and slurping with abandon. "You taste so good, Shouta-kun! I mean… Master!" Shouta had let go of her horns and started to clutch the sheets. He truly felt for the first time like he was under the influence of succubus powers! His unnatural penis was huge, hard, and leaking all over his narrow chest, forming a patch of wetness on his shirt. Lucoa hissed around his asshole, pausing to kiss and suck his buttocks, worshiping the softness and pertness of the young flesh there.

"It's so degrading… that you're telling me to kiss you down there, as if your butt was my boyfriend!" Lucoa announced, apropos of nothing.

"I… didn't tell you… to do that!" Shouta wailed, but regardless, the wheels were set in motion, and Lucoa planted a wet, submissive kiss of servitude directly on his asshole… then hollowed out her cheeks as she started to suck his young ass, tornadoing her tongue around spit-moist rim and jerking his cock all the while. Syrupy bursts of pre-cum began to fly through the air.

"Ah… if you keep doing that…" Shouta groaned, clenching his teeth. "Something is coming!"

Lucoa's eyes went wide, and as Shouta's small body tensed, she shot into action, pulling his huge cock forward toward her mouth, and rising up from her all-fours position so she could slip her mouth over it. She was just opening up to take the huge, quivering cockhead through her lips when the first burst of chowdery, off-white semen burst against the side of her mouth. "Ah! What a waste!" she moaned, dismayed, and quickly slid her mouth over Shouta's glans, her jaw creaking as she struggled to take the size of it. From there, she adoringly massaged his twitching sack and milked his shaft as his body tensed and jumped with each burst of semen.

SPLUUUURG! SPLUUUURT! SPLOOOOORT! Lucoa's distinctive multi-colored eyes rolled back slightly and sperm burst from the sides of her mouth and out of her nose, dripping down her chin. She squatted whorishly while her throat worked to swallow the thick, chunky mess, and she was obviously loving the volume and thickness of it, if her adoring caresses of Shouta's smooth ballsack were any indication. She made gurgling noises as she struggled, swallowing four, five, six, seven times while stray sperm slopped down onto her bare breasts. The choker of her made costume undulated as her neck bulged and retracted with the grotesquely big chugs of semen she was taking down to her stomach.

When his emission at last subsided, Shouta's limbs were limp and he lay, dazed and his eyes glassy, with his half-hard cock flopping up against his thin chest, still leaking a tiny bit of semen. Cradling her belly, Lucoa crawled up onto the bed beside him, playing with his cock and rubbing him gently, a pet with a favorite toy. Shouta, for his part, could only let out an exhausted moan. It had been the first orgasm of his life, and, aided by the magic spell, had nearly blown his mind. A great, all-encompassing release - and the fact that Lucoa, his rival, was absorbing it, somehow made it all the more satisfying.

Lucoa put a fist to her mouth and stifled a burp, swallowing thickly. "That was such a huge load, especially for someone your age!" she confided. "And it was extra-stinky, too! It really smells like squid. You shot so much, it's like the smell washed over every bit of my body!" She waggled her eyebrows. "You know, right now, this body of mine is using your extra-thick cum to survive! Isn't that lewd? If I'm not careful, I'll become your woman, just from getting filled with so much!"

She leaned in close, her lips brushing against his ear as she spoke mischievously. "If you like, you could order me to eat nothing but your cum from now on-"

But Lucoa didn't realize that her manipulations had reached their limit, and Shouta, thanks to the spell, had reached a new level. The boy gritted his teeth and reached out a hand, grabbing her closest horn, yanking her roughly and then shoving her head away. "Shut up, you fat prostitute!" he cried. "Why don't you get summoned to a soapland so you can suck cock all day if that's what you want to do!" He sprang to his feet on the mattress, showing a level of animation and confidence that was the opposite of his usual demeanor. He pointed at her with an arm that was as rigid as re-hardened cock - which was glowing a sinister purple and flashing with runes.

Lucoa's eyes went wide. "Shouta-kun!" she gasped. "Your big cock is… filled with magical energy! And you're talking with confidence!"

Shouta looked down at himself. The monster dick between his legs wasn't actually glowing, but both he and Lucoa, sensitive to magical power, could detect an aura around it. It had returned to full hardness and looked ready to go a second round.

"Say more stuff to me!" Lucoa. "Like you just did!"

Shouta tried to remember what he had said, but couldn't. It was as if the words were part of the spell - the sexual, alpha-male BDE that was needed to subdue a succubus had been summoned into him, just as the cock had replaced his small one. New words came to mind effortlessly.

"Don't order me around, you stupid cum tank!" he yelled, standing on the bed like a king on a balcony, addressing his court of one. "Give me one more suggestion and I'll slap your fat fuck-jugs around until you're crying for mercy!"

"Oooh!" Lucoa purred, swooning. "Yes, Master! Mistreat me more!" Her face was adoring instead of bothered, though, which only annoyed Shouta. He hopped down to the floor and gave another sharp order, stripping his shirt off as he did so, standing totally nude and without shame, his cock an iron bar that jutted out with grotesque size from his diminutive, pale, hairless body. He stood with feet shoulder-width apart and made his decree:

"Crawl around like a dog and give me a ride!" 

Lucoa jumped into action quickly, prostrating herself on all fours, with Shouta lifting a leg over her back like a cowboy mounting his mare, laying his fat cock in her shoulder blades. Lucoa had barely started moving when he lifted a hand and slapped it down on her thick, jiggling ass, creating a whap noise that echoed off the walls.

"Giddy-ap!" he cried. Lucoa swooned and nodded, and started to crawl around in a circle, while Shouta bonked her on the head with the tip of his cock, punctuating the humiliation of the moment with regular slaps and whacks in the back of the head. "Look at you!" he taunted. "You can barely crawl around because your big, fat tits are scraping the floor! Apologize to me for being such a cow!"

"I'm sorry I'm such a cow, Master!" Lucoa wailed. "Please, slap my boobs a lot so I'll learn my lesson!" She took her medicine with a smile she didn't bother to conceal. Indeed, the primal, animal sexuality that Shouta was exhibiting reminded her of the 'good old days'.

WHAP! Another blow to her rear end, spurring her onward. "I told you not to tell me what to do, comfort woman!" And so, Lucoa served as Shouta's maid-mount, crawling in a rough circle on the floor of his room, absorbing blows to the meatiest parts of her body - her boobs and rear end. Through it all, the boy's huge penis was leaking hot nectar all over the back of her neck, and he continued in his ride until he grew board, his small body saddled atop her laboring, larger one.

At last, Shouta swung a leg over and hopped down, leaving Lucoa on all fours and panting… and with her round, heart-shaped ass looking rather vulnerable. He rubbed the tip of his cock against the crotch of her black maid panties, intending the meaty lips of her cunt-mound with his leaking knob, and drawing out moans.

"Spread your ass and pussy!" Shouta ordered. The vulgarity of the language would previously have send him into sweat-drop conniptions, but the power of the succubus-slaying spear was flowing through him, lending him confidence. He stood behind her with arms crossed as she desperately tried to obey, reaching behind and pulling down her black panties to bare the pink crescent within. Then, once the panties were down and wrapped around one calf, Lucoa put her boobs on the floor (they flattened into big, bulging discs) her ass in the air, and spread her cheeks like a sow with two hands… right in Shouta's young face!

"D-don't look!" she said, absurdly, blushing deeply. "This is so humiliating, Master!" But she didn't exactly sound unhappy about it, and indeed, her cunt was soaking wet after nearly ten minutes of being degraded, verbally abused and ridden around the room like a horse.

Shouta, confronted at last by the forbidden zone that he'd only heard about in dirty jokes and in the pages of illicit manga, felt a compulsion emanating from the long, iron-hard fuckpipe that emerged stiffly from his pubis - the compulsion to slide his meat into that steaming, quivering, whorish bitch-box!

"Don't act like this isn't what you wanted all along, succubus!" he accused, walking forward and using a small hand to poke experimentally at Lucoa's slit. Two of his fingers slid inside with remarkable ease, and it was unspeakably warm, wet, and tight within! "Your bitch hole is trying to take my whole hand inside!"

"Don't say that!" Lucoa moaned, still holding her cheeks wide, putting herself on lewd display. Then, Shouta tucked in a third finger, then a fourth, and her eyes went wide. "Wait!" she blurted. "My delicate flower-"

"Shut up!" Shouta spat, and tucked his thumb in, forming a fist, and jamming his entire hand inside Lucoa's cunt. "Look at this whore hole! You're soaking wet and your prostitute demon pussy wants more and more!" Shouta was small enough and slender enough that his hand and wrist penetrated into Lucoa with relative ease, all the way up to the elbow! Lucoa's eyes crossed and rolled back in her head.

"Uwauuuuuuugggghhh!" she wailed, and her tongue lolled out of her mouth. "If… you keep… doing that… I'll… hnnnnngh!" Her body shuddered and her back seemed to arch even more. Shouta watched her reaction with the harsh conviction of a demon-slayer who was about to sink his blade into the heart of an enemy - the succubus was, he saw, finally showing her true colors! And thanks to the spell, instead of running away in embarrassment, he was prepared to strike the final blow!

GOOOSH! Shouta rammed his arm in to the elbow and pressed his fist directly up into Lucoa's womb. Lubrication sprayed all over his arm and shoulder, and Lucoa's eyes rolled back to the whites as her naughty, flirtatious pussy was forced to submit to a roiling, body-wracking fistgasm… all at the hands of a cute eleven-year-old boy! Shouta was taken aback by the tightness inside her, and the feeling of his whole arm being massaged, milked , almost, by the tissues of her vaginal canal!

"So this is the secret technique of a succubus!" the boy announced, fancying himself a burgeoning demonologist. "No wonder no man can resist you!" He withdrew his arm and Lucoa collapsed to the floor, her body twitching, uttering moans every few seconds. There was a puddle of lube between her legs from where she'd shamelessly creamed all over herself and Shouta's slender, boyish arm. Her boobs were splayed to either side of her face-down body as she lay totally flat.

Shouta made his move. The succubus-slaying spear was as big and hard as he'd seen it yet; what most would consider foreplay, he saw as the sharpening of his weapon to strike the final, dispelling blow! Moving quickly, he straddled Lucoa's upper thighs, tore away her skirt, and used his hands to press down on his cock and force it into line with the entrance to her pussy. As soon as the knob touched her cunt lips, Lucoa became animated again, gasping and looking wearily back over her shoulder.

"Ah! Shouta-kun!" she cried. "It's not a safe day! If you do that… I might end up having your baby!"

Shouta rolled his eyes as he clambered just behind the soft hills of her butt - as if a whorish succubus had such things as 'safe days' - and rubbed his leaking, throbbing tip against her slit, up and down. "Shut up!" he said. "You're just making excuses to try to stop me from banshing you, demon!"

"But I'm not actually a- uuwwaaagh!"

Shouta planted his toes on the floor, threw his head back, and tensed the muscles of his cute, round bottom, planting two palms on Lucoa's ass-cheeks and giving the mightiest thrust his small body could muster. There was a wet sound of fleshy displacement as his pipe burrowed into her pussy, instantly penetrating as far as it could go in the well-lubed channel, bullying the entrance to her womb. 

"Ah! It's in!" Lucoa blurted. "It's… poking at my special place! Shouta-kun's huge cock is kissing my baby bag!" She was moaning at the stimulation, which was providing her divine reproductive parts with sensations they hadn't felt since the era of the Aztecs. Indeed, it was even more forbidden than the oft-referenced case where she'd consumed too much liquor and then, with her younger sister-

"I'll shove it all the way in!" Shouta announced, and began to thrust in regular time, making Lucoa's bottom jiggle with the impact of his smooth, hairless pelvis. Taking a bow-legged stance that lewdly showed every detail of his penis and hanging balls, he dug his meat into her with stroke after cunt-stretching stroke. His oversized, virile nuts slapped powerfully against her clit with every downstroke. "Take it! Now I see the power of the succubus-destroying spear!"

Something was being destroyed all right - namely, Lucoa's pussy, by what seemed to be sixteen inches of throbbing boymeat! Each stroke caused a spritz of lube droplets to squirt out, and the noises of churning flesh coming from inside her body were totally obscene - so much so that she blushed a deep red while in the throes of her forbidden enjoyment. "Ah!" she cried. "Don't listen to the naughty sounds, Shouta-kun!"

"I can hear them all!" Shouta retorted, keeping his grip firmly on her jiggling ass as he pumped his hips. "I wonder what Tohru would think, about the sounds of your whore hole sucking on my big dick!" He dig his cock in extra deep, wiggling his hips around as he cudgeled Lucoa's cervix with his glans, and then sloooowly pulled it out, causing an exaggerated schlooooorp from her tight, dick-hungry pussy. Lucoa blushed even redder. "Apologize, succubus!" Shouta scolded.

"I'm sorry my wet, whorish pussy is making such lewd sounds!" Lucoa moaned, and yelped as Shouta spanked her ass and buried his cock back inside, spurring her on to further confessions. "It's because I'm a slut for the big dicks of cute boys! I can't get enough of having my indecent pussy stirred up by kids who aren't even in high school!"

Whop. Whop. Whop. Whop. The fucking continued and Lucoa's blatherings lost coherence and gained a fragmentary quality as she had her pussy churned up. "If you push… any further… Shouta-kun… you'll shove right into my womb! If I'm forced to have hot, degrading womb sex with such a huge penis… I'll become your woman, and give birth to your child! I'll become nothing but a bitch who pops out the children of her master!"

"Good!" Shouta announced, and proceeded to do exactly what Lucoa had 'warned' him about - though the question of whether she was subtly guiding events by her own perverse hand was still an open question. The busty dragon wailed like a fire alarm as Shouta pushed up as far as he could go, his hairless crotch flush against her buttocks, and buried his long, curved penis into her baby sack. Her eyes crossed and her eyelids fluttered as her tongue lolled out. 

"It's… huge!" she drooled. "I'm… getting messed uuuuup!" Her body twitched along with the shallow, grinding strokes that Shouta was using to plow deep inside her. "The place… where a child is supposed to grow… is filled with diiiiiiiick!"

"It feels… really good!" Shouta gasped. He felt a sensation building inside his newfound penis of power, and had a pretty good idea what it meant. For a moment he felt some of the old nervousness and embarrassment, and his face was the familiar expression of red-faced lip biting. But he was determined to see the act through, even if it was embarrassing. It felt too good to stop.

"Beg for it!" he ordered, his breath growing ragged.

"I want you… to cum inside my womb!" Lucoa groaned, twitching underneath him like a swatted bug. Though her adult body was much larger, she'd been rendered totally immobile by the enervating spasms of orgasmic, shotacon breeding sex, and Shouta was balancing his tiny frane on her thighs and big ass while he drove his cock over and over again into his conquered prize. 

"Say it more vulgarly, succubus!" Shouta ordered. Something was definitely building up 

"Use this stupid whore's semen-toilet womb and knock me up with your kiiiiiiiiiid!" Lucoa wailed, cumming so brutally that it short circuited her divine brain. She and Shouta cried out in unison, both of their voices high - hers due to femininity and his due to his immature age and small size. A great explosion of both power and pleasure seemed to emanate from the boy's enhanced penis, and it started to erupt with such an unnaturally virile spray of semen that it instantly filled Lucoa's womb to the brim - and flooded her channel so quickly that it splattered back out onto the floor within seconds, all accompanied by the wet, churning sounds of the ultra-thick semen.

Just looking at the thick curds of sperm as they slopped back out of Lucoa's pussy, there could be no doubt that she was being impregnated by Shouta's massive, belly-bulging, ultra-virile load. The boy threw back his head, enjoying the most powerful orgasm he'd likely ever have, crying out, and then stumbling backward as a great power seemed to rush out of his body. There was another schloorp noise as he tumbled and his cock pulled out of Lucoa's pussy, followed shortly by a thick and amazingly copious creampie that piled next to her well-fucked hole like an avalanche of cum.

Eyes shut, heart beating fast, laying on his back, Shouta knew the job was done. The spell had fulfilled its purpose, and no doubt, the banishment was complete. He listened and heard nothing at all. No breathing, no moaning. It was likely, he realized, that Lucoa had been forced back to the demon world, and no trace remained. He felt a bittersweet feeling of regret that it was over. She had been good-natured enough, but her temptations, huge boobs, and insistence on bathing with him and sneaking into his room… 

"It had to be done," he murmured, enjoying the quiet. Still with eyes closed, his hands explored down toward his crotch. His instincts as a mage were sharp, and he'd felt a great outrush of power. His inkling was confirmed when he felt not a huge, unwieldy flesh pipe but only his former small, cute, hairless member - with a case of phimosis that he'd been cagily hiding from Lucoa, who tried to see him naked at every opportunity.

Now, he could finally be at peace, and resume his studies as-

He felt breath in his face.

Shouta opened his eyes and found a face leering directly over him. Heterochromatic eyes. Curved horns. Baseball cap. Clueless smile. Inappropriate levels of interest in his middle-school-aged body.

"You cast that spell really well, Shouta-kun!" Lucoa said, smiling. She was wearing her tank top again - she had reconstituted her former as easily as snapping a finger, it seemed, and the maid outfit was nowhere to be found - but as she lay on her hip, leaning over him, her breasts gave way to a huge, gravid cum-belly that pressed against his side and stretched the black cotton fabric! "Look at this amount! I look like I'm already pregnant!"

For a beat, Shouta was too astounded to react. Then, he flailed his arms and legs and blushed red in true Shouta fashion, scrambling like a startled roach to the side of his bed, and uttered a high-pitched wail. He was back to his old, easily embarrassed self - proof that the spell had truly run its course. Without effect, apparently!

"You can't be here!" Shouta protested. "I banished you!"

Lucoa shook a finger. "Ah ah! I told you I wasn't a succubus, Shouta-kun!"

"You admitted you were a succubus!" he cried back, exasperated. He couldn't believe all his work - and "other" activities - had been for nothing. "You said it a bunch of times!"

"I wanted you to feel like you were doing a good job!" Lucoa explained, cheerily, then rubbed her belly again and arched her eyebrows suggestively. "It obviously worked! I'll be happy to pretend to be a succubus for you tomorrow, too! There's still plenty of fertility knowledge I used to teach people, that a growing boy should learn! Like anal sex!"

"No!" Shouta objected, shielding himself with his hands. 

But of course Lucoa ignored him, becoming lost in remembering her former role as goddess, listing depravities out finger by finger. "Paizuri, and facials, of course… and sometimes, people used to pee on each other!"

"I really don't need to learn that!"

"Well, we're going to be spending a lot of time together," Lucoa went on, holding her belly. "After you shot all of this cum into my womb, I'm pregnant for sure! And you're going to have to take responsibility!" She smiled sweetly. "And I get really horny when I get pregnant so… I hope you're ready to cast that spell a bunch more times!" Then, with a blush: "We can even do that maso-play you like… and you can treat me as roughly as you want!"

Shouta's lip quivered and his eyelids twitched. He could only stare straight ahead. Then, after a moment, he cried out in fear and ran out of the room. Lucoa watched him go, naked and skidding along in his bare feet, with a quizzical expression on her face. "Shouta-kuuuuuuuuun!" she called after him. "Don't worry, I'm a goddess, after all! I can take it!"

He ran down the hall, then down the stairs. Lucoa watched him go with her usual smiling, unphased expression. She was excited. Having a child in this human-looking form would be the most interesting thing to happen to her in centuries. And if it was a boy, perhaps it would grow up to have a huge penis like the one Shouta had used to impregnate her! 

In such a case, she imagined, the boy would need proper guidance from his mother!

EPILOGUE

Slrrrrk. Slrrrrch. Slrrrrrk.  

Shouta's eyes fluttered open and he saw his coverlet rising and falling through morning-blurred vision. That, and the weight on the bedspread with him, revealed that Lucoa was beneath the covers, doing her usual duties. He lifted them up and saw her seductively and wetly stuffing her face with is fat, half-hard penis, burying it down her throat. Her eyes, half-lidded and seductive, were hungry for semen.

Shouta gritted his teeth and moaned. A thick burst of wad pumped out of the end of his penis, spraying from his coin-slot pisshole and pumping into Lucoa's stomach as she held her head obediently in place. It always felt good to empty his big balls right at the start of the day, and Lucoa, heavily pregnant, was always hungry for more 'nutrients for the baby'.

With practice and as a result of a lot of nagging, Shouta had increased his aptitude with the Succubus Slaying Spear spell, such that he could maintain the sixteen inch, arm-thick cock through several orgasms and even while sleeping. After months of developing his magical skills, his current record was six orgasms before it 'poofed'. At the same time, this meant that he was able to maintain his confidence and the artificial 'big dick energy' that the spell provided…

…much to Lucoa's pleasure.

"Get off of my dick," he groused, kicking her away with his feet, causing her to roll to the floor with a moan, her mouth plastered with cum. He swung his legs off the bed and addressed her with a stern face that was undermined by his cuteness but at least earnest. "Don't you ever get enough cum, you fat, pregnant toilet sow? Go get my breakfast ready!"

"Yes Master! This dumb big-titted breeding bitch will prepare your food right away!" Lucoa wailed, and then obediently left the room. Shouta took a deep breath, stretched, and smiled. No matter how badly he treated her, Lucoa seemed to like it more and more. And thanks to her nigh-invulnerable form, there was nothing he could really do to harm her. One thing was for sure, though - he much preferred having the confidence to handle her, rather than flailing his arms and running away at her inappropriate, shota-lust flirtations.

His cock, pulled free of his waistband, was hanging half-hard against his thigh. Shouta gave it an experimental tug, feeling the weight and virility of it, and smiled again. He would, he decided, practice the spell some more that evening. It might even be possible to increase the power.

And this power was something he could definitely get used to.
