Chapter Text
“Long have I studied your abilities, Slayer.” Aura stood across from the elf, a smug smile on her face. The demon stared down her old foe, using her free hand to throw back her fluffy, pink hair. On first glance, she might appear to be merely a diminutive, unimposing lady, short with a modest, perky chest, and a skirt that did a little to de-emphasize pleasingly wide hips. Yet the way her opponent stared at her made it clear that she was not in any way being underestimated. “I considered using my usual tactics to smother your free will, but then I considered something more… interesting.”
“Oh?” The elf’s eyes narrowed into an even stronger glare. She came out expecting Aura to use those scales she was so fond of to compare their mana, a move she’d been ready to go up against for years, but it sounded like Frieren was in for a twist. Very rarely did demons put a twist on their prized ability. She didn’t like that, but it was too late for anything but reacting to whatever oddity Aura was about to unleash.
Mind control was an immense power, but one with a cost. It could not be done freely and without risk, there was simply no one powerful enough to snap their fingers and take control of another’s entire being. As someone who did not enjoy the idea of someone trying to take control of her mind for obvious reasons, Frieren’s magical wards had always been able to repel those sorts of spells, but Aura was known for giving her spell enough of a weakness that it could overcome her shields.
Adjusting her grip on her staff in case she had to reposition, she watched the demon raise the scales, and a pulse rang out across them. That did not seem any different from her usual tactics, but there had to be something new.
Grinning, Aura spread her arms wide, clearly offering Frieren a free shot.
A powerful spear of magic struck the demon in the chest, harmlessly dissipating.
“I assumed it would do something like that. It was worth a try.”
“Within my new magic, we can do nothing to harm one another. Our magic will not affect the other, and even if one of us drew a small blade, it would be unable to pierce the weakest skin.”
“How uncharacteristically pacifistic of you. Going to tell me that demons and humans can live together?”
“Hmph, don’t credit me so yet. We can bring one another no harm, but that says nothing of pleasure.” An odd electricity went through the air that the elf wasn’t sure how to describe. Her heart pounded faster, warmth surging across her cheeks and up her long ears.
Grabbing her skirt, Aura threw it aside, revealing a sight that even Frieren had to stare at, disbelieving what she was seeing with her own eyes.
A penis was affixed to Aura’s crotch. Even as it was drooped and limp, the phallus was far larger than any other that Frieren had caught sight of in the less stuck up societies which had come and gone through the eras, thicker than her wrist and growing in size by the second.
“Do you like it~?” Aura snickered, using her free hand to caress her cock, stroking its twitching veins as it grew thicker, longer, curving upwards. “No doubt you feel an arousal that is unfamiliar for a sexless elf like yourself. You don’t know how to handle it, but my cock right here looks wonderfully intriguing, does it not~?”
“It doesn’t fit you.”
“I suppose simply being aroused doesn’t do anything about that tongue of yours,” Aura sighed, stepping closer, what had grown into a foot long cock bobbing ahead as she strutted towards the elf. They came far closer together than Frieren would ever want, able to feel the other’s breathing, with Aura’s overlarge endowment pressing against her clothed stomach. “Let me tell you the rules of this spell: whoever makes the other climax three times first gains dominance over their entire being.”
“I see.”
“How does it feel knowing that I am about to make your mind so numb with pleasure that all other thoughts will slip away, leaving you a sex craving husk of a woman, thousands of years of knowledge all wasted~?”
Glaring at the horned woman, Frieren just scoffed. “You overestimate yourself. Just because you’ve given yourself a blade that makes no wound doesn’t mean you can wield it properly.”
Despite her confident words, this was looking bad. Frieren didn’t know the first thing about sex. Of course, she’d heard various whispers over the years, but nothing that made her feel strongly about betting her freedom in a sex competition.
Not only that, but as Aura shoved her to the grass, it was made clear that the demon was physically more powerful than Frieren.
The elf was thrown onto her back, landing legs apart, slim thighs parted by the demon’s knee. Hair scattered in its twin tails to the sides, she looked up past the modest swell of her chest to where the pink haired demon loomed above menacingly, looking like a beast about to feast. Had it been a normal battle, Frieren would have used this proximity to obliterate her before she could throttle the elf, but she had prodded at the magic around them to confirm Aura was not bluffing. Whatever force was compelling them had distorted the rules of this space, and no harm could come to either.
Smirking like a fool, Aura slammed her log of a manhood down upon Frieren’s pussy. She laid it across her covered lips, the heaviness sending a shock through the slender girl’s system. Gasping loudly, all of her attention was suddenly on the way the heavy tool throbbed atop the lips she realized were more sensitive than anywhere else, its thick head pointed at her face.
The position gave Frieren plenty of time to truly take her member in. It was as long as her forearm and thicker around the middle, a jutting log of flesh, hot as a furnace. Plenty of foreskin clung around the pink head, looking like it could be peeled back from the tip. Below, a pair of hefty balls were partly hidden by both of their hips, but what little the elf saw implies that they were big, each needing a full hand to lift.
“There’s more to this magic. Some hypnotic suggestion, preventing me from looking away…”
“Stupid elf. You’re horny, and you’ve seen a fat, juicy cock!” She started to slide it, up and down, grinding the thick, heavy underside between Frieren’s puffed up pussy lips.
“Ridiculous… Elves don’t… Mmm…” Frieren shivered, even though she was warm.
Aura’s confidence swelled at the sight, her vision struggling to stay focused. “Elves have no sexual drive, and yet, they are one of the most susceptible races to sexual stimulation if they’re already aroused. All it took was a spell that put you in a state of heatedness, and you became weaker than a kitten. You’ve already lost, Frieren.”
“That’s not… ah… true…”
“Then why have you not looked away from my cock since first it started to grind you into the dirt, hm? Tell me, Slayer, what is running through your head as this virile spear threatens to break you into a sex addicted serf even before my command has entered your slutty head~”
Aura spent a lot of time researching the kind of behaviour that made someone sexually submit. When this new spell became the demon’s fixation, she studied the words humans used to break each other, and was finding that, unlike emotional responses, the physical titillation that came with sexual domination was indeed something a demon was fully capable of experiencing. Watching Frieren moan and shake, helpless beneath her, made the predator lick her lips, cock burning with lust.
“Say it, elf!”
“Ahh… It is merely… eye c-catching… Sticks out l-like a… a sore thumb… so big… pointed at me… making me h-hot…”
“Burn within this inferno raging in your pussy. You can feel it trying to erupt, like a volcano spewing its warmth… Let it out!”
“Ahh…”
“Release it upon my virile spear, elf! Let your fire free!”
“Ahhh… ngggh… O-Ohhh!”
With a shrill cry, cum sprayed from Frieren’s pussy. Juices squirted against the heavy cock, flying in all directions but up as the shaft pressed down on her cumming hole. Aura did not blink once, taking in the sight of Frieren’s erotic release, a hand clutching her cheek, the other wrapped around her stomach as she jerked her hips and bit her lips, burning from nose to the tips of her ears.
Behind Aura, a small flame appeared in one of her scales.
Watching the elf’s modest chest heave as she caught her breath, the demon let out a laugh. “That was so easy! I did not think a person could reach orgasm so quickly, so effortlessly! Two more, and you will be my mindless sex toy, Frieren. Remember the last days of freedom you had fondly, for-”
Magic rose up within Frieren, a spell cast. It made the demon flinch, survival instincts alert purely from how much magic was being conjured in her face. She had to remind herself that nothing could be used against her while their contest was active, which could only mean that she was casting a spell elsewhere.
“Sending some kind of distress call to your friends? Hmph. Foolish. With how quickly you orgasmed, they will never reach here-”
“Ahhhhhh~” Letting out another moan, Frieren’s modest chest suddenly surged skywards, growing from cute apples to bloated, head sized melons that exploded from her shirt, loudly tearing it apart so they could bounce in the open air. Below Aura’s cock was another lurch as her hips and ass expanded in much the same way, a flat little bottom springing into a juicy booty that would make any voluptuous dancer jealous. Hips spread from slim to childbearing, wider than her shoulders, and it only looked more exaggerated by a tight snatching of her waistline, every bit of fat squeezed out.
Even her lusting face had changed. Eyelashes were thicker, much longer, and her lips had a new, full shine to them. The short, slim elf became a sexy, ridiculously busty, yet still short lady!
Staring in shock at the sudden change that occurred before her eyes, Aura was easily thrown onto her back. With a grunt as her head hit the grass, she tried to sit up again, only to hiss when Frieren slammed her new bust down around the twitching cock, wrapping it in two absurdly soft pillows. A surge of pleasure shot through the demon, her arms giving out, forcing her to lay there, beneath the busty woman.
“That was the last key I needed,” Frieren panted, grabbing the sides of her tits and pressing them together. Aura’s twelve inches stuck out from the top, twitching against her soft lips, still shining and wet with the elf’s orgasm. “You told me that you are just as much of a virgin as I am, despite your confidence.”
“Huh?!” Aura tried to growl, but had to moan when Frieren lifted both of her breasts up, and dropped them down, over and over. The slickness from her last orgasm only served to lubricate her new tits, pleasure shooting through her like bolts of lightning.
“Don’t bother trying to move. In my curiosity for what makes humans tick, I read many books involving what they like so much about sex. Within them, this,” she smacked the side of a breast, sending a ripple all the way to Aura’s throbbing cock, “disables them utterly. None can compete with the pleasure given by a larger than average bust.”
“In what way is this merely ‘larger than average,’ elf?!”
“It’ll do even better, then.”
Human sex books expressed feelings she didn’t know, so trying to interpret the arousal of other species killed time. Both Frieren and Aura had engaged in a contest that neither were mentally or physically prepared for, mimicking second hand knowledge, with their freedom on the line.
“You h-had this magic at the ready?!” Aura groaned, clutching her cheeks with both hands, her cock stirring in ways she didn’t know it could.
“Eruption of Womanhood Magic. I dislike that I had to use it. I’ve not yet found a spell that reverts it,” Frieren muttered, cheeks still burning as she glanced down at the fat, jiggly spheres that had once been her manageable breasts. As much as she envied Fern’s sizes, her taller body was not only braced to carry such extra weight, but Frieren was used to her physique. Over a thousand years as a small, slim elf meant that she had no desire to change something so fundamental and irreversible. She did not want to stand out as a short woman with a bust larger than her own head, a backside that would wobble around annoyingly every time she took a step, and such a tightly compacted waistline that she felt like a living hourglass. Even doing this, on her knees, bent down, she could feel how whatever happened to her breasts had aftershocks back there.
She looked obscene, and that would take some getting used to. The only reason she engaged the spell was because she could tell that she needed any possible advantage to retain her freedom.
Though…
She could not deny that it was giving her plenty of physical stimulation. She really thought that when the books described one’s breasts bringing them pleasure, that it was an exaggeration by the writers. She’d tried to bounce her own breasts upon reading those words, but it just felt like she was swinging her chest flesh around, nothing more.
At this size, with a throbbing cock in there pushing them apart, slickly sliding between her tits, Frieren moaned heatedly, lips vibrating against the head. The scent of sex filled her nose, the precum bubbling at the tip smearing across her lips, tongue darting out to taste its musky heaviness.
“How do they feel, Aura?” She would turn the demon’s dirty talk back on her. “Do you feel yourself on the verge of orgasmic release due to the motions of my individual breasts?” Frieren was not as good.
She didn’t need to be.
The pleasure wrapped around Aura’s cock was driving the demon mad! Staring past her bust at Frieren’s titjob, the elf’s heavier lashes and pouty lips turned her blank stare into naturally alluring bedroom eyes, tongue constantly lapping at the underside of her cockhead, heavy tits sloshing around her desperately tensing shaft. She could not believe that what was merely two large breasts, two sloshing sacks of fat, could push her this far. Her cock tensed, sack clenching in a way the equally virginal demon had never experienced.
She could do nothing but moan as cum fired from her cock like it was a semen cannon. Neither were prepared for the hot rush of seed as it got Frieren in the chin, the elf trying to hold her composure as a barrage of spurts struck her from below and splashed down, soaking her swollen bust.
The scales, which had started to tip one way, were matched by an identically small flame on the other. It was balanced, the scores even.
