On a dark night in the tallest tower of a castle deep in the demon realm, Adam was reading some tomes by candlelight. He had a handsome face and brilliant green eyes like his father, but his pale skin and disheveled white hair hinted at his nature as the world’s first natural born incubus. However the vestigial wings sprouting from his lower back, his long sinuous tail, and the small horns that barely poked out from under his hair proved that the demon lord still had a lot of work ahead of her. As he continued to read, Adam failed to notice a figure enter his room from the window. It silently approached him from behind while he was too engrossed in his tome to notice.
“BOO!” the figure said as she tickled his side, and Adam screamed before trying to break away. The figure simply laughed as she tossed him onto his bed. Adam quickly sat up to find his older sister Feu sitting in the chair he had previously been occupying. The lilim had red, yellow, and orange streaks in her hair and had tattoos of flames etched over her body. The bra and panties she was wearing barely covered her D-cup breast and luscious ass, but were also enchanted to produce magical flames that would keep the lilim modest. However the flames grew or shrank based on Feu’s mood, and were currently burning low which allowed Adam to practically see everything. Her yellow eyes glinted with mischief as her brother looked away in embarrassment.
“What do you want Feu?” Adam asked after she finished chuckling.
“Mother asked me to keep an eye on you while she and father are gone for the week, and I was curious as to why there was a light coming from your room,” Feu explained. “Mother would be furious if one of my fiery friends were found fornicating with you. They’re unfortunately not the right type of mamono for mother.”
“I can see why,” Adam admits as images of Feu fiery delinquent mamono friends flash through his mind. “I was just reading.”
“That’s no good either brother,” Feu chastised in a sing-song voice. “Just what would mother say if she knew how late you were staying up just to read?”
“She won’t say anything if she doesn’t find out.”
“That’s true, but what kind of big sister would I be if didn’t tell her that my adorable baby brother was misbehaving?”
“So we’re back to my original question then,” Adam said with a sigh. “So what do you want?”
“I want you to go hero hunting with me,” Feu admitted.
“Sorry, but mother and father don’t want me doing anything like that yet.”
“Such a rebel,” Feu sneered. “Willing to stay up late to read dusty tomes, but doesn’t want to do anything fun!”
“I think its fun…” Adam mumbled, although his sister ignored his comment.
“So get your stuff ready for an early morning tomorrow. I don’t want to waste too much time getting ready when there are heroes to seduce.”
“I don’t want to go hero hunting Feu.”
“And why not? Don’t you want to help grandmamma with her mission?” Feu asked. “Don’t worry if you’re scared of getting hurt. I’m sure you’re stronger than any hero, and I’ll be there to help.”
“It’s not that I’m scared…” Adam admitted.
“Then why don’t you want to go?”
“I… I don’t think I can actually do it… My powers aren’t that strong, and I-I’m not that good at dealing with women…”
“You seem to be ok with dealing with me,” Feu noted.
“You’re different Feu…”
“Then why don’t you pretend you’re dealing with me?”
“That’s just wrong on so many levels…” Adam groaned. “Why would you even suggest that?”
“You never know,” Feu said with a chuckle. She walked over to a nearby bookshelf, and started looking through the books as she said, “And as for your powers, they don’t have to be strong to be effective. All they really need to do is make a distraction.”
“What are you doing?”
“If we’re going hero hunting, we’ll need to pick an appropriate target. Here we go,” Feu said as she pulled out a book, and started looking through it.
“I told you I’m not… going…” Adam trailed off when he realized which of his books she was looking at. It was this year’s Registry for Female Heroes. As its name suggested, the hero registry was a book that contained profiles for every active duty hero. This was done to help heroes get certain benefits for their good work such as discounts at inns and shops, or free equipment repairs. Each hero also carried a badge that they received when graduating from their academy, but the hero registry helped combat the use of stolen badges and mamono subversion. It was also a must have item for anyone who idolized heroes or enjoyed looking at the expertly painted pictures of the heroes, which was why Adam had a copy of the Female Heroes edition. He didn’t know what was more humiliating: having his sister peruse his fap material, or the fact that she knew he had it in the first place.
“Of course you’re going! It sounds like you need to go, so I’m not going to take no for an answer!” she chastised as she approached him. “And I found you the perfect target~!” She placed the book in front of him. The page she had shown him was the profile for woman named Eve. She was a commoner who had been sponsored by her local church for some undisclosed reason. She seemed to be an average hero who didn’t seem to excel in anything particular. She was also very average in appearance. She had long chocolate brown hair, brown eyes, a common but pretty face, and slim frame that her leather armor kept mostly hidden.
Adam looked at Eve’s profile for a moment before asking, “Why her?”
“Because she’d be perfect for your first hunt. She’s not too experienced, she’s alone for some reason, and I happen to know that she’s in the area so you don’t have to go too far. So what do you say? Ready to go charm her pants off?”
“And if I did go ‘charm her pants off’, which I won’t, what would I do after that?” the incubus asked.
“Depends on if you like her or not,” Feu explained. “Like her: make her your wife! Don’t like her: you can just pump and dump her!”
“Alright then. Just keep her then. So go to sleep. We’re going to have an early morning!”
“I told you I’m not going on a hero hunt with you,” Adam protested.
“You say that like you have a choice,” Feu said with a sly smile.
“And what makes you say that?”
“Because if you don’t I’ll tell Divampare that you want to train with her,” the lilim said as the magic flames on her clothes grew and spread. Divampare was a salamander who was particularly passionate and boisterous. Additionally she was one of those salamanders who thought that a man asking to train with them meant that they were interested in them romantically, which meant Adam would be subjected to intense training from dawn to dusk until he could give her the glorious fight she so desperately wanted. To Adam that would be a constant, living hell. He tried to come up with a rebuttal, something to keep him safe from that torture, but nothing came to mind. As he began to accept his fate, he began to see Feu as one of the great and terrible demon lords of old. “Good boy.” The next day they both left the castle before dawn. Feu had replaced her magical burning clothing with a form fitting grey sweater, and she was still enticing despite the drab color. Adam had also changed clothes, but he was much more embarrassed by what his sister had made him wear. He was now wearing an expensive looking silver cuirass that left most of his stomach and abs exposed. He was also wearing a short apron with metal plating that he kept trying to pull down in fear that people could see his penis as they hid behind a rock outcropping next to a rocky path.
“Do I really have to wear this?” Adam asked. “I don’t think this armor would actually protect me…”
“It’s meant more for the cheesecake factor instead of actual protection.”
“Oh. C-could you at least have made this apron longer? You can almost see my junk?!”
“That is a bit of a problem,” Feu admitted. “You’re quite a bit smaller than I thought.”
“Hey… What do you mean by ‘smaller than you thought’?” Adam asked indignantly.
“Don’t worry about it,” Feu said as she waved her hand to dismiss her brother’s concerns. “You should be focusing on how you’re going to seduce this Eve girl.”
“I still don’t think I’m going to be able to do that…”
“Oh please! You need to have some confidence in yourself! I mean look at these!” Feu said before she started stroking her brother’s abs. “How did a bookworm like you get these? I know dozens of ladies who’d kill just to be able to touch these.”
“Father insisted that he teach me martial arts,” Adam admitted uncomfortably as he watched his sister stroke his muscles. “C-could you stop that?”
“Huh? Oh sure.” Feu stopped rubbing her brother. They stood in awkward silence for a moment before she added, “I’m sure you’ll do fine. Just do what you feel is right.”
“I feel like the right thing to do is to go home and read.”
“”If you do that I’ll tell Divampare and Ember that you think they’re sexy,” Feu warned. Images of Feu’s salamander and hellhound friends dominating him ran through Adam’s head, and he shivered. “That’s what I thought.” Feu then suddenly reacted as if she had heard an alarm that only she could hear before saying, “That’s the proximity alarm I set up, so she’s almost here! I know you can do this Adam! Good luck!”
“Feu! Wait!” Adam cried out as his sister vanished in front of him. He cursed under his breath before floating up to the top of the outcropping. He then used the rocks for cover as he kept an eye out for Eve. The human hero appeared soon after as Feu had predicted, and Adam studied her carefully. She had replaced the leather armor she wore in the hero registry with a leather tunic with overlapping steel plates covering her chest and stomach. She also wore steel rerebraces, vambraces, and gauntlets on her arms, and greaves that she wore over her brown tights. Her chocolate brown hair had been tied into a long ponytail, and she carried a plain broadsword on her hip. Adam began to feel nervous once he noticed her sword, but he reminded himself of what would happen to him if he ran and opted to stay. It seemed that he feared his sister’s friends more than he feared getting stabbed. He hid behind the rocks until Eve had passed him, and he threw a rock behind her to get her attention. She quickly looked behind her with her hand on her sword, and jumped back in surprise when she noticed Adam hovering over the rocks. “F-f-finally! I-It’s about t-time you n-noticed me,” Adam stuttered as confidently as he could manage.
Eve was unimpressed, and drew her sword as she asked, “An incubus with wings and a tail? What kind of freak are you?”
“Who are you calling?! I mean, I’m no freak,” Adam said after almost losing his cool. “I am Adam, the first incubus born into this world, and proof that the Demon Lord’s plans are coming to fruition!”
“You’re still a freak no matter how pretty you look!” Eve spat back. She blushed when she realized what she had said and yelled, “You may be pretty, but it’s not like I find you attractive or anything demon! I-I don’t care how you look or dress, so I’ll never be distracted by how good you look! I mean… Damn it…” Adam looked at Eve curiously. She had her gaze trained on him like any professional hero would, but she was blushing up a storm and couldn’t seem to be able to focus on any part of him. He began to blush at this revelation, and resumed trying to cover his crotch. “W-what are you acting all embarrassed for?!” Eve asked in indignation. “Aren’t you supposed to be some super confident sex demon?!”
“E-even sex demons can get embarrassed when someone’s raping them with their eyes!” Adam countered.
“I am not raping you with my eyes!” Eve protested before falling silent.
“You are raping me with your eyes!”
“I can’t help it! You put that idea in my head you freak!”
“How does that even work?!”
“Y-you know… It’s like when someone tells you not to think about pink elephants, and all of a sudden you’re thinking of pink elephants!”
“But I never told you to not rape me with your eyes! You started doing that on your own!”
“Lies!” Feu, who had been watching from a safe distance away, could hardly contain her laughter at such a ridiculous scene. However she managed to continue watching as Adam and Eve got increasingly frustrated with each other. Eventually their argument devolved into petty insults. “Well I bet that you’re still a virgin despite being so good looking!”
“Can I help it if my parents can be a little overprotective?” Adam spat as is tail writhed in annoyance. “What’s your excuse? The guys didn’t like you staring at them like some sort of creep?”
“For the last time: I wasn’t staring at you!”
“But you just called me good looking again!”
“Look. Could we just… Stop arguing like this, and fight or something?” Eve exasperatedly asked. “This is going nowhere, and I want to beat the snot out of you.
”Y-yeah. Sure,” Adam agreed. He also made a note to never go hero hunting ever again. “Ready?”
“You better believe it!” Adam said nothing before launching himself at her like a bullet. Eve waited until he was within her range before slashing at him with her broadsword, but Adam dove under her blade. He rounded on her, but immediately had to dodge a flurry of clumsy slashes. “Could you stop moving?!”
“Maybe you work on your aim a bit instead?” Adam asked mockingly as he continued to dodge. “How did you even graduate from the hero academy if this is all you can do?”
“All this coming from someone who’s just been dodging this whole time!” Eve shouted as she put more power into her swing. She swung her sword in a wide arc while shouting, “Why don’t you try fighting back?!”
“Because I’m trying to give you a sporting chance,” Adam said as he dodged once again. Eve overextended her strike, and wound up hitting the ground. “Because I can easily do this!” Adam bragged as he kicked Eve’s sword out of her hands. “At any time since my father is the great fighter Aste-!” Eve abandoned her sword, and slugged Adam in the face before he could finish bragging. He stepped back, and barely had enough time to counter Eve’s grapple. He tried to overpower her, but to his horror he found that he was being overpowered instead. “W-what the?!”
“Surprised?” Eve asked smugly. “You were wondering how I graduated from the hero academy, so I guess I’ll tell you. I got a sponsorship from the church because I’m crazy strong! When I was ten I was able to lift a man twice my size! I was only using that sword to make stupid monsters like you drop their guard!” She continued to force Adam to his knees as he tried to come up with a way to counter Eve’s surprisingly overwhelming force. “So are you ready for me to crush you freak?”
“Sorry, but I’m not getting crushed today!” Adam shouted defiantly.
“And how are you going to manage that?
“You’re not the only one with a trick up his sleeve!” Adam shouted as he tried to grab Eve with his tail. However to their horror his tail ripped through Eve’s tights, and began to writhe against her crotch.
“J-just where d-do you t-think you’re putting that thing?!” Eve protested through her moans.
“D-don’t get the wrong idea! I-I was just trying to grab your leg, not your… It was an accident!”
“Accident?! You aim for my leg, and grab my crotch?! Do you think I’m stupid you pervert!”
“I’m not a pervert! Do you know how hard it is to accurately control your tail when you’re stressed?!” Adam asked, but his only response was a knee to the stomach. Eve then threw him against some rocks before rushing to grab her sword while Adam was stunned. He tried to get up, but he found Eve’s blade against his neck before he could budge.
“It’s time for you to pay for what you did to me you perverted abomination,” Eve declared, although her heavy breathing and blushing face made her look more like a jilted lover than an Order hero. “Any last words before I end your life?”
“F-Feu! H-help me!” he cried out as he tried to back away in terror.
“Is that all you have to say for yourself? No confessions? No apologies to a certain heroine who you just groped with your tail?” Eve asked. “Whatever.” She gripped her sword with both hands, and raised it above her head.
“ADAM! ADAM YOU’VE GOT TO RUN!!!” Feu screamed as she flew towards them as fast as she could. However it was clear that she wouldn’t get there in time. “ADAAAAAM!”
“F-Feu!” Adam cried as he tried to shield himself from the incoming blow. He waited for his life to come to an end. And he waited. And he waited. He eventually grew tired of waiting, and peaked at Eve. She still had her sword raised over her head, and she was trembling as if something was keeping her from moving. Feu landed next to them, and looked at the hero curiously.
“W-what did you monsters do to me?!” Eve demanded.
“I didn’t do anything. What about you Feu?”
“I couldn’t have,” Feu admitted.” I only know fire magic.”
“Weird…” Adam started to stand up, but stopped when he noticed a pink sludge dripping out of Eve’s vagina. “Huh? What’s..?” Eve moaned as the slime flowed out of her in a torrent, and caught Adam. “Hey!”
“Well would you look at that,” Feu said with a smile. “That explains why she was out here on her own. She’s a slime carrier!”
“N-no I’m not! Ah~!” Eve protested, but slime pouring out and enveloping her was clear evidence that she had been infected by a parasite slime. “S-stop ah~! It~!”
“H-hey! Let me go!” Adam shouted as the parasite slime pulled him closer to its host. It had removed his clothing, and had begun to stroke his cock until it was erect and throbbing. The slime had also begun to take off Eve’s armor, and was eagerly teasing every inch of her exposed skin. “Feu! Help me!”
“I would love to little brother, but this slime looks really hungry,” Feu said. “Besides, I have a feeling that this might be good for the two of you.”
“W-what are you trying to say Feu?!” Adam asked incredulously.
“Y-yeah! Make it stooooop~!” Eve moaned as the slime began to grope her small breasts.
“Actually, I think I’ll give you two a bit of privacy,” Feu said as she began to fly away. “I’ll be back in a bit to see how you’re doing. Don’t do anything I wouldn’t do you crazy kids!”
“FEEEEEEEUUUUUU!” Adam yelled as he watched his sister fly away. Eve tried to fight the slime, but they both moaned loudly as the parasite slime forced her to impale herself onto Adam’s raging erection.
“I wonder what I should tell mom and dad though,” Feu wondered aloud as she flew away.
