Chapter Text
It was a regular afternoon inside Axel’s Adventurer’s Guild. The room was brimming with chatter, and two Crimson Demons sat at a table—accompanied only by the beer mugs that littered the space between them.
Of the two, Megumin was the most easily distinguishable—thanks to her oversized wizard hat.
And it wasn't just any regular wizard hat. Its golden band was crisscrossed with red lace, like jagged teeth, accented by the button eyes over top. That, in combination with her short red shoulderless dress, black fingerless gloves, belt-like choker, genuine belt around her stomach, and asymmetric stocking/bandage combo that covered her legs, her outfit screamed Crimson Demon fashion. And to top it all off—draped over the shoulders and back of her slender body—was a long flowing cape.
Despite her disarmingly small stature, she was the archmage famously known for helping to defeat the Demon King, and infamously known for waking the townsfolk with her daily Explosion magic.
Sitting across from her was, of course, Yunyun, the extremely capable to-be chief of the Crimson Demon Clan.
Her red stockings, pink skirt, and black long-sleeve button-up blouse was relatively more normal. Except, not normal was, again, her belt, as well as the strangely angular cutouts on both the bottom of her blouse and around her breast area. And speaking of her breasts, especially compared to Megumin, she was a woman with a proper set of assets. Though, that didn’t help her make any friends, nor did it stop the town from pitying her inability to.
At the moment, there was silence between them, and it wasn’t the tranquil kind either. Rather, they were both simmering, hot off a lopsided argument where Yunyun was rehashing who “won” the most competitions, and Megumin was arguing why that didn’t matter. It was a completely absurd back and forth that, nonetheless, wrung them both dry.
In the midst of this silence, there came the chatter of two women who came to sit nearby.
“Have you heard about the new guy?” One prompted.
“I don't know, have I?” The other responded. “Is it the one just down the street?”
“It is. I hear he’s got quite the package”
“Oh, that he does. But it wasn’t the only monstrous thing about him. Even I couldn’t keep up.”
“Really? That’s a first.” They both giggled.
“How about I give it a go?”
“It’s quite the challenge, but sure, knock yourself out.”
The word latched onto Megumin’s mind like a parasite.
…Challenge, huh?
She gave a side-eye to her drinking buddy, suspicious. Yunyun seemed to be tipping back another beer without a care in the world, but Megumin knew there was no way the other mage wasn’t thinking about it.
This was the girl who made a competition out of literally anything she could find.
Although, a random stranger that they had just heard about? Yunyun wouldn’t stoop that low.
…Would she?
It was the following day at the guild, but this time, only one of the mages was present. Meeting here was a casual routine of theirs, which meant that it wasn’t uncommon for one party to be late—this time it just happened to be Yunyun. So, Megumin didn’t think much of it and just ordered for herself.
She had just begun to make a dent in her drinks when she spotted her missing partner finally walking through the entrance. Megumin didn't pay the girl any mind until she arrived at the table.
But once Yunyun did arrive, it was clear that her face was slightly flushed and there was a blatant wet sheen covering the neck of her clothes. Megumin opened her mouth, ready to pipe up and ask what spilled on her, before she noticed something odd.
The strange fluid covered not only Yunyun’s clothes, but her large breasts as well—complete with an undeniable pool of white gathered in her cleavage.
Yunyun didn’t hesitate once she saw where Megumin's eyes were pointed.
“Oh, what’s this?” She noted, pulling her collar aside, giving a clearer view of her stained jugs. “A special someone had a good time with these. Too bad you could never.”
It appeared that their argument from before wasn’t anything to scoff at.
In the face of a challenge, Yunyun was dedicated enough to actually soil herself like this, and lowly enough to strike Megumin where it hurt.
The smaller mage just sighed.
What was she going to do about this self-proclaimed rival?
Megumin gave the door a polite knock.
If her intel was right, this should be the right place.
A few moments later, the door opened and revealed a torso, clothed in a simple brown fabric. Megumin took a second to realize that that was just how tall the man was, before tilting her gaze upward to meet the face that the wide brim of her hat had kept hidden.
It was a rather average, if a bit scraggly, looking man—a man who seemed rather confused by her arrival.
“What do you need?”
Megumin steeled herself. “I’m here for…”
A confusing mix of anxiety and shame swirled through her, burning her cheeks with a warm blush. She couldn’t believe that Yunyun did this… but she did. And that meant Megumin could too.
“Your thing.” She finalized.
“My thing?” The man echoed
“Yes. I’m here to… get you off.” She teasingly tugged her collar down… as if the V cut wasn’t already showing off what little there was to display.
Her blush intensified as he stared blankly back at her. She felt as if she could explode from embarrassment.
“…Are you two planning something?”
“Huh?” Megumin glanced around in search of this second person.
“You and the other Crimson Demon who was here yesterday.” The man specified.
“Oh." Megumin was frowning now. "I have nothing to do with that woman.”
“So you do know her, then?”
“…Fine, I have a little to do with that woman.”
“What are you trying to accomplish, trying to seduce me?”
“What does it matter? Are you turning down my offer?” She gave one last push, clenching her fists in worry.
This wasn’t exactly a private space, and she couldn’t tolerate much more public humiliation.
The man took a deep breath in, then audibly let it back out.
“…No, I guess not.” He confessed.
“Then could I come in?” Megumin asked, rather urgently.
“…Sure.”
They both stepped inside and routed to the bedroom, letting the door close behind them.
She was supposed to pleasure this man… how, exactly?
Megumin was frozen solid, paralyzed by the one-eyed glare of the massive, meaty shaft stretching towards her.
Her forearms were considered thin, but for this cock to be the same thickness—now that was just absurd. It luckily wasn't as long, but she couldn't be too certain. It didn't seem to be fully erect.
This terrible appendage… it was what Yunyun and her dumb chest had somehow conquered. Megumin wasn't fortunate enough to have such tools, but unlike that other girl, she did have some actual experience to leverage. She knew what got men going.
Well, a simple offer of sex would get them riled up, but wasn't the point. This battle was more than that. This was about making this man succumb to her womanly charms—to her erotic body.
Rather than the tit-flashing, clueless bimbo act that Megumin was certain her rival had employed, she would instead become the mature, sultry woman whose mere touch would make heartbeats quicken.
Allow me. I’ll be the one to take care of you. Megumin had said, dancing her fingers along the man's thigh, not knowing what she was signing herself up for.
Then came her whole charade of noticing his bulge, smiling all cockily, and thinking to herself that she was doing something right as she seductively removed her gloves. Then her voicing her curiosity as she crouched down to face his crotch—only for a weapon to pop out when she pulled down his trousers.
…Which led her to now: her, stuck on her knees, still staring doe-eyed at the hunk of meat.
As if responding to her intense gaze, the shaft twitched upwards, bumping the brim of her hat. She was thankful for the privacy her hat provided, as it kept the man from judging her tense expression—the sight of this monolith moving autonomously had brought her to the brink of a cold sweat.
I have to pleasure him… with my body, Megumin quickly reminded herself. And to do that, she at least needed to start.
Reaching forwards, she grabbed onto the appendage with both her hands, soon discovering the vibrant heat it radiated, and that her fingers weren't able to close all the way around it. Her nerves were shaken—it was intimidating enough to make her avert her gaze, but she wasn't going to be stopped just yet.
She gripped a bit tighter, stroking back and forth along his member, her fingers nearly hitching on his bulging veins. Once she'd gotten a good sense of his firmness, one hand began squeezing near his glans, while the other… couldn't reach much further back—not without bringing herself closer to this behemoth.
“This is gonna take all day…” The man murmured from far above.
“Shush. I know what I’m doing.” She retorted.
At least, she thought she did. This member wasn't reacting like she expected, and her frustration was beginning to bubble up. She was certain that this would get the job done eventually, but could she live with herself if she did?
Even if she came back with evidence to show, she wasn’t sure she could face Yunyun's own achievement. Even if Megumin tried to embellish her feat, they’d known each other for too long. Yunyun had gotten a lot better at catching lies.
Plus that girl was scary when she was angry.
Did using her chest actually work? She wondered. The shaft seemed almost uninterested.
Gathering her courage, Megumin uneasily brought her own chest up to it, and frowned. The fleshy warm head poked rather unremarkably against her collarbone.
“Are you sure you know what you’re doing?” The man pestered.
“Ah, um. Yes."
"Then why are you doing… whatever that is?"
Megumin stayed silent, now beginning to stroke him with her chest, though it was more like dragging his tip along an ironing board.
"Hello…? What is going on down there?"
"I need to do this!" Megumin suddenly piped up, jerking her head up to face him, "She said I’m small and unattractive!”
She spoke more from her heart than actual memory.
“Wha—Unattractive…? You?” He stammered back at the beauty staring back beneath the hat.
“Hmph, what? Got something to say about it?” She pouted.
The man leaned sideways, catching a glimpse of her shapely lower half, currently squishing against the floor.
“Well… I wouldn't call you small…”
“Oh, is that so…?” Megumin wore her doubt freely.
"Yeah?"
"So you see me as a proper woman?"
"I… I guess?"
“Liar. As a woman, I’ve got no sex appeal.” Her hands had already drifted to her chest as she said this.
The man just scratched his head.
"But that's why I'm here." Megumin continued, "To prove to that slut-shaped simpleton that I've got plenty of sex appeal to spare—enough to please someone like you."
The man continued to stay silent, trying to parse the words of this crazed woman.
“So, I need you to, at the very least, act like you're attracted to my chest. Can you help me with that?”
“I… Sure, I can help you with that, but…” He stared at her chest and made a face. "Why your chest?"
“Ugh! You—!" Megumin nearly shouted, before biting her tongue, "…Just do whatever you need to get off on your own. I’ll think of a way to beat her.”
She stomped over to his bed and took a seat on the edge, hanging her head in deep contemplation.
The man had followed behind her, which she only realized once he removed her hat and found him stroking himself off.
“W-What are you doing?” The mage cried out.
“You said to do whatever I need, right?”
"But you said my body—" Megumin began.
"Your chest." He corrected, interrupting, "Which is cute, and for holding onto, not sticking a dick between. But if pleasing a man is what you need to do, then I don't know why you're giving up. You're already well equipped for that."
“Huh…?” The girl couldn't wrap her head around what all he was saying. She thought it was clear that she wasn't good enough.
“What's so confusing? Are you trying to copy that other girl, or are you trying to beat her?”
Megumin took a moment to consider his words, before quickly brightening up. Of course!
She was supposed to beat Yunyun! Just like she always did. And she emerged victorious not by doing what Yunyun did better, but by perfecting her own craft—and maybe even twisting the challenge a little.
“Then, do you have any lube?” Prompted the smaller girl.
From her seat upon the edge of the bed, Megumin had laid backwards, lifting her legs to form an L-shape with her body. The man stood below her legs, right at the edge of the mattress, using his own body to help keep her legs upright as she tightly crossed them.
And tying together the whole scene: The man's girthy cock, glistening with a generous coat of lube, lodged directly between her plump thighs.
He was fucking her legs.
…Or rather, in the name of the challenge, she was jerking him off with her thighs.
Megumin just watched, mesmerized as the slab of meat slid rhythmically back and forth, disappearing and reappearing from between her supple, hugging masses. He was massaging the muscles there, on the insides of her thighs, and melding his body heat with hers.
Even though its intimidating size was still just that: intimidating, it was also beginning to stir something inside her.
Big was her thing.
Big styles. Big spectacles. Big enemies. Big entrées. Big boobs. Big booms.
These were things that brought joy to her life, or outright gave it purpose.
And so, facing this big cock now without shying away, she found herself finally catching onto its appeal.
Basking in its presence felt… right in some way.
The way it thrust through her legs, its rigid mass pushing her soft meat aside as she squeezed it from either end—it made her wonder…
What would it feel like inside her?
Her instincts found this horrifying, but beside her prickling fear laid something else entirely: an immense curiosity.
Would it even fit?
…She doubted it. Something that size would surely wreck her body.
But what if, somehow, it could fit. And what if, somehow, it ended up feeling good?
Something that large could certainly do a lot of loving.
A jolt brought her back to reality, and Megumin found herself breathing heavily, her face heated by a blush.
She then realized, after some wet smacking filled her ears, that his hips were forcibly pounding against her. A spectacle that was complimented by the sight of his shaft swiftly slipping in and out, and the feeling of his sack occasionally bumping against her butt.
He's being so rough…
It scrambled up her thoughts—every blunt impact sent a tingling up her spine. His power—his lust, it was coming through with striking clarity.
And even though it was through her clothes, and even though he wasn’t pressing very hard, he was still stroking her sex—with his manhood, nonetheless.
Her blush deepened, and she quickly realized she couldn’t even hide her embarrassment.
“I’m close. Where do you want it?” He suddenly spoke.
“Wha— You’re asking me?” She yelped.
She'd completely forgotten about this part. What was she supposed to do again? Yunyun had kept it in her cleavage, but without that option…
At this rate, she was going to end up walking around town with a cumstain on her dress, laid out for all to see.
“N-Not there!!” It was all she think to say.
Hoping he’d pull out and find somewhere else to shoot, she braced herself, waiting for him to make his move.
Instead, his arm reached out.
And what it reached for—was her hat.
“Wait—!” The mage pleaded.
Much to Megumin’s dismay, he didn't wait and simply began to unload—directly into her hat.
An angry indignation surged up in her chest as she felt his shaft throbbing powerfully between his legs.
But as the seconds drew on, her anger was quickly jumbled up with awe as she felt it failing to stop—his semen kept on flowing.
Once it finally petered out, “Whew… Never done that before…” he muttered, sounding plenty satisfied.
Megumin just stared at her hat-turned-basket of cum, wracking her brain on how to proceed next. She had to find a way to turn this in her favor.
Whatever she did, though, Megumin knew that she couldn’t give Yunyun the satisfaction of knowing the challenge was accepted—not until the moment was perfect, that is.
Megumin walked into the guild and immediately locked onto her fellow Crimson Demon. As she approached, she noticed Yunyun was clearly searching her expression for any confrontational emotions, but to no avail—the smaller mage was oddly nonchalant.
Like normal, Megumin adjusted her dress and held her oversized hat steady as she slid onto the opposing bench.
“…You’re just gonna let me win?” Yunyun couldn’t help but make a jab, partially in disbelief.
“Win what?” Megumin responded innocently.
“The challenge. I know you understood what I meant yesterday.”
“Yesterday…? Hmm… I was pretty busy that day, so I can’t really remember… Remind me again, will you?”
“You—Fine!" The busty mage blushed, then shouted under her breath, "I jerked off that super hung guy with my boobs!”
The smaller one scrunched her face like she was thinking, then suddenly brightened up as if she remembered. “Ah, right. So it was that… That’s silly.”
“Huh? How can you say such a thing?”
“Because anyone can do that.”
“Wha—You’re just saying that because you can’t! I bet you just came back from his place after learning that for yourself!”
“Well, you’re right. I did come back from his place.” Megumin conceded.
A grin crept across Yunyun’s face.
“But while I was over there…” Megumin continued.
The smaller mage suddenly tipped sideways, leaning off the end of the bench. Yunyun couldn’t understand what she was doing, but when Megumin came back upright, her hat had been removed from her head.
Megumin then placed it onto the table, upside down. Yunyun watched in pure shock as it tipped towards her, spilling white sludge out of the crown and dripping slowly down the wide brim.
Glancing back up, Yunyun found that atop her rival’s head sat a thick glaze of something also white and glisteningly wet.
“I helped him relieve a lot of stress.” The smaller girl goaded.
Yunyun simply gawked.
“So, I’m guessing drinks are on you today?” Megumin beamed.
Thus, the gauntlet had been thrown.
