Riser x Kunou
A/N: Kunou here is older than her canon counterpart. How much older is up to you to decide.
Summary: Ravel got her own Evil Pieces and a new Peerage member.
Money really does make the world go round. While it can't buy you everything, it can buy you things to get what you want.
Case in point, Sacred Gears. I can't exactly buy Sacred Gears themselves since that's not how they work but I could buy myself one of the few Sacred Gear extractors that are floating around. After that, it's just a matter of looking for the Sacred Gear I wanted and extracting it from the individual.
This is something I thought of doing after learning of a particular Sacred Gear not mentioned in the show. Wings of Ascension, the Sacred Gear that houses the soul of the Primordial Phoenix/True Phoenix and is one of the few beings that willingly allow themselves to be sealed. It's the "original" Phoenix from which all Phoenix descended and the only one that could be said to be truly immortal and the origin of the Phoenix rebirth ability. While normal Phoenix and my Phoenix-powered family have powerful regeneration that makes us hard to kill, we can still be killed.
The Primordial Phoenix, on the other hand, will revive from its ashes every time it dies but in doing so, it'll be reborn as a new individual with only fragments of its previous self. It also only has a "lifespan" of 500 years before it goes up in flames and has to be reborn.
That's why, when the God of the Bible went around sealing various beings, it went to said God itself to be sealed into a Sacred Gear, to prevent itself from losing its current self. Doing so comes with the benefit of being able to pick and choose who it gives its abilities to. If it wakes up in a host it doesn't like, it can simply refuse to supply any power.
While the Sacred Gear can be considered quite weak as it only gives its user a pair of wings for flight and control over fire, those that gain the Primordial Phoenix's acknowledgment can unlock its Balance Breaker and access the Gear's true power, making it on par with a Longinus. It's only because few ever gain the acknowledgment of the Primordial Phoenix that Wings of Ascension isn't counted as a Longinus.
Sadly, its previous user died shortly before "canon" started and its current host is nowhere to be found. That is still an ongoing search for me.
Still, I got the Sacred Gear Extractor so I set about using it to empower my Peerage.
First up is the Sacred Gear, Oblivion Glove, which can turn anything it touches into bombs including people. It's not all that strong since people can force out the power of the Sacred Gear using their magic, ki, etc but in the hands of an expert, its power can become devastating.
Obviously, I gave it to Yubelluna who used it to augment her explosion, making it even more powerful. If her explosion was powerful enough to take out an unprepared Rook before, it's now powerful enough to blow them to pieces.
Next are two of the same Sacred Gear. Advance Arsenal, a Sacred Gear quite similar to Bladed Blacksmith and Sword Birth if weaker than those two in terms of power. What it lacks in power though, it makes up for it in versatility. It can not only create swords but other weapons, shields, armor, and even modern weapons like guns. However for that last one, you need to know how they work in the first place to make them.
I gave the two Gears to Ile and Nel who then proceeded to make chainsaw swords, chainsaw shields, chainsaw armor... chainsaw everything. If they can think of it, they will make it and then add spinning death blades to it.
Last but not least, I also acquired both Bladed Blacksmith and Sword Birth for my two knights, Karlamine and Siris respectively.
I planned to get more in the future for the rest of my Peerage if only so they won't get jealous, but I couldn't find any that fit them at the moment.
Speaking of my Peerage, Kuroka officially joins my Peerage. After some talking with Ravel, we decided that it's best if she gets her own Evil Pieces so I can add Kuroka as my Bishop. She was reluctant at first but seeing that she's my little sis and doesn't need the excuse of being part of my peerage to be with me, she agreed in the end.
Ravel got her Bishop piece replaced with a substitute King Piece, since normal King Pieces are banned, and was given her own Evil Pieces courtesy of Ajuka. Which gave me back my Bishop piece that was then promptly traded away to add Kuroka to my Peerage, again courtesy of Ajuka since Kuroka's old master was dead.
She even found her first victim- er, Peerage member in the form of Kunou using a Bishop piece. Little Kunou keeps getting targeted by people trying to force Yasaka to do their bidding. In their most recent attempt, they got way too close for comfort and only failed because Ravel "just happened to" be in the area to help.
Then, being the Master Tactician that she is, Ravel manages to make Kunou join her Peerage. Yasaka was against it at first but Kunou, being the smart little bugger that she is, knew she would only cause her mom trouble if she stayed so she went to Ravel to join her Peerage.
Yasaka can only reluctantly agree to it after Kunou becomes a Devil and finds out it was her own daughter's idea, though not without putting up some conditions of her own to make sure Ravel doesn't do what Kunou is trying to prevent and abuse the poor girl's power over her mother. They even signed a Devil Contract and everything.
Ravel agreed to it of course because according to the contract, SHE is not allowed to do anything to Kunou. It didn't say anything about helping her brother do "all kinds of things" to the poor girl.
I can't help but feel proud of her. My little sister really is a little devil and while I don't exactly plan to seduce every girl I see, I'm not against adding more girls to my harem.
As for Kunou's age... Well, we're devils, only humans, and stuck-up supernatural factions care about that. The way I see it, Kunou is smart enough, if she is ok with doing it(even if she is being manipulated by Ravel), I'm not going to hold myself back.
As I was typing away on a computer, Ravel barged into the room.
"Hey, big bro, are you busy right now?" She asks. She has taken to calling me that since she found hentai on my computer.
"Nothing much, just chatting with some people on the internet. I have a lot of time to kill before the Young Devils Gathering tomorrow." I answer.
More specifically, I'm chatting with a certain vampire shut-in with timey-wimey power about his "big sister" who is being manipulated by their half-brother and abusing her power despite the power's negative effect on her mind.
While I was tempted to get a Longinus user on my side, Valerie Tepes comes with too much baggage I don't want to deal with. Plus, if I'm going to add a girl to my growing harem, I don't want to do it because of their power. That's a great way to create relationship problems later on. It also comes with the added benefit that Rias might not go to the Young Devils Gathering once she learns of Valerie.
"Great, then come with me." Ravel cheers, dragging me away from my entertainment(watching a cross-dressing dhampir freak out online).
"Wait, where are we going?" I ask.
"It's a surprise. I did tell you I was still preparing your birthday present. I'm done with my preparation now. I'm sure you'll love it!" Ravel answers, dragging me through the mansion toward the dungeon.
After the long walk, we arrive in front of a door, which Ravel opens with ease. Inside is a small room, the walls decorated with paintings and other works of art. There's also a large bed with flower petals scattered around. On top of a bed is a naked, tied-up Kunou. Her hands are tied behind her back, her legs are spread out and bound to the bed, and her eyes are blindfolded.
"It might be late but here's your present!" Ravel says, gesturing to the tied-up Kunou.
"Really?" I ask, looking at the scene.
"Hey, it was her idea to tie herself up and offer her to you this way. I only convinced her to sleep with you," Ravel says, shrugging off the blame.
"Uh-huh, and I'm sure it's also her idea to look up S&M porn on my computer?" I retorted. I thought Ravel only "researched" it for herself, but apparently, she's been using it to corrupt other girls too. I was wondering why my Peerage was being a bit kinkier lately.
"O-Of course not..." Ravel stammers, her cheeks turning pink.
"A-anyway, we're not here to talk about me, we're here for you and Kunou~" She quickly changed the subject.
"Y-Yes, Kunou is ready," Kunou answers, looking nervous.
Ravel takes a seat next to Kunou and pats her head. "It's alright, you can do this. You're already doing better than when we started training!"
Kunou blushes redder, not answering.
I step forward and help take off her blindfold. She looked away, too embarrassed to look at me.
"Did Ravel "convince" you to do this, Kunou? You know you don't have to do what she says if you're uncomfortable with it." I ask, trying to make things clear.
"N-No! Kunou- I want to please big brother," She answers.
Right, I unofficially adopted her as my 2nd little sister after helping her out of some of Ravel's crazier schemes. She grew attached to me and started looking up to me as a big brother figure... which Ravel then twisted into something perverted. Now that I think about it, that might have been Ravel's intention from the start.
I look at Ravel in asken without speaking. She sticks her tongue out playfully, confirming my suspicion.
I turn my attention back to Kunou... the naked, tied-up Kunou. Helpless and ready to be taken at any moment...
'Damn, Ravel really knows how to get my motor going.' I think, admiring the view.
"Well, if that's what you want, then I won't stop you. Just be careful not to let Ravel influence your decision too much." I tell her, setting a hand on her thigh.
Kunou jolts at the touch and her tail stiffens.
"O-okay, big bro," She responds, still looking away from me.
"You know, I never thought I'd see you like this, Kunou," I say in amusement, my hand slowly crawling up her body, from her thighs to her hips.
"Kunou wanted to be a good little sister for my b-big bro." She replies, her breath getting heavy.
"That's right, Kunou, you're a very good girl~" Ravel chimes in. "Why don't you show him how good you can be and get him going?"
"O-Ok." She answers, finally looking at me with her cute face. "Little sisters exist to serve their big brothers. Please use Konou in whatever way you desire. Kunou's body belongs to big bro now."
Her face is red with embarrassment, but her words and eyes are sincere. She wants me to use her.
"Heh, is that so? In that case, I'm going to take your word on that and treat you however I see fit." I say, leaning over her and pinching her nipple, causing her to gasp.
"Ahh- P-please put the blindfold back on. Kunou wants to feel everything with her body instead of seeing it." She asks, her face still red.
"Very well, as you wish," I place the blindfold back on her.
With her vision blocked, her sense of touch is heightened and every touch I make to her body causes her to jolt in pleasure. Her breasts, her nipples, her butt, and her thighs, they're all fair game. I caress her whole body, enjoying the feeling of her soft skin.
I lean in and plant a kiss on her lips, catching her by surprise. She opens her mouth and I slip my tongue in, exploring her mouth. I can feel her body shudder as I kiss her.
We pull away from each other, a string of saliva still connecting us together.
"That was your first kiss, wasn't it?" I ask.
"Y-yes." She admits, blushing.
"How was it? Do you like it?"
"I-it felt good, very good." She answers, licking her lips.
"I'm glad. Now, let's see what else can make you feel good~" I reply, sliding down her body and planting kisses on her neck, her collarbone, her stomach, and finally, her crotch.
Her legs are spread wide, exposing her vagina. I can see that she's already wet from the attention.
"Oh, looks like you're ready," I say, taking a finger and sliding it along her slit, earning a squeal from her.
I press down on her clitoris and she moans. I then take my finger and lick the juices off it, tasting her.
"So sweet~"
"Nnnnn- Big Bro, please..." She pleads.
"What do you want?"
"Kunou wants big bro to take her virginity and use her as he pleases. Kunou's pussy is aching for her big bro's cock." She replies, her chest rising and falling as she pants.
'God, that's hot. Who knew innocent little Kunou could be this lewd.' If I weren't already hard, that would have put me at full mast instantly.
I take off my clothes and toss them to the side. I slide the tip of my dick along her pussy, making her squirm. I then place the tip right at her entrance.
"Here I go," I announce.
"K-Kunou ready." She answers, bracing herself. "Please ravage Kunou's pussy with your huge cock and make her into a woman!"
Hearing those words from her mouth made my cock twitch. I push my cock in, forcing the entrance open and filling her up. She groans as I sink my dick into her tight pussy.
"A-ahhh! It's so big, Kunou feels like she's being split apart." She exclaims, her breathing becoming heavy.
"Does it hurt?" I ask after pushing myself inside her completely.
"Y-Yes, but it's good pain. Kunou wants more~" She answers, wiggling her hips.
'Huh, she might be a bigger masochist than anyone else in my harem,' I think to myself, looking at her expression. She seems to be enjoying it, even though she's clearly in pain.
I pull out slightly and thrust back in, earning a cry from her.
"Nnnghh- Ahhh!"
I repeat the process, picking up the pace. I begin to thrust my cock in and out of her, making her moan with each thrust.
"Ohh- yes! Nnnnggghh- Kunou loves this!" She shouts.
I reach for her breast and fondle it, adding to the stimulation.
"Ah- Kunou's boobs are being played with while her pussy is being penetrated. It feels so good~" She comments, her voice laced with pleasure.
I lean down and kiss her again, silencing her. She eagerly accepts my tongue into her mouth and sucks on it.
"Nnnngggggghhhhhh- Mmmmmm"
Her muffled moans drive me wild and I continue pounding her. After a while, I feel her pussy contract around my dick and she orgasms, her juices gushing out and dripping onto the sheets.
"Ahhhh- Haaaah" She cries, her body convulsing.
I slow down to give her time to recover. After a few moments, she catches her breath and speaks.
"W-why did big bro stop?" She asks, her face flushed red.
"You just came, I'm giving you time to rest."
"But big bro hasn't finished yet. Kunou wants big bro to fill her needy womb with his cum." She says, wiggling her hips, making my dick twitch inside her.
"You really are a slutty little sister." I chuckle.
"That's right, I'm Kunou's big brother's personal cum dump. Kunou exists only to please her big brother." She answers, smiling at me.
"In that case, you better prepare yourself. I'm going to use you until I'm satisfied, got it?" I say, my voice becoming stern.
"Yes, please use Kunou to the fullest. Kunou will gladly accept anything you give her." She says, her tail wagging behind her.
"Very well."
I grab her hips and pull her towards me, driving my dick deeper into her. I begin pounding her with vigor, not holding back.
"Nnnnggg- Ohhhhh!" She screams, her back arching.
My cock penetrates her deepest parts, making her body writhe.
"Ah- Kunou's womb is being ravaged, big bro's dick feels so good. Kunou's mind is going blank." She mumbles, her face contorted with pleasure.
I keep going, thrusting into her, using her body. Her pussy tightens around me, sucking me in.
"Your pussy feels amazing. I can't get enough of it." I praise, slamming into her harder.
"Oh- Ah- Kunou is so happy to hear that, Ah- Nnnnngggghhh," She moans, her face filled with ecstasy.
We go on like this for a while, our bodies joined as one. Eventually, I can feel the pressure building up inside me and I know I'm getting close.
"I'm almost there. I'm gonna cum soon." I warn.
"P-please, give Kunou everything. Kunou's pussy needs your thick, hot, virile cum." She begs, her voice quivering.
With one final thrust, I plunge my dick deep inside her and unload. My cock erupts, shooting ropes of thick semen into her pussy, filling her up.
"Ahhhhh- Ha-haaaaaa- Y-yes, Kunou can feel her big brother's cum flooding her womb. So good~"
Her body quivers and she orgasms again, her pussy contracting around my dick and squeezing out the last bits of cum.
"That felt great," I say, pulling out of her.
"Mmmm- Kunou feels so full~" She says, her pussy leaking with cum.
"You did a good job, Kunou," I tell her as I take off the blindfold.
"Really? Kunou is happy to hear that." She smiles.
"Hey, what about me?" Ravel whines, sitting next to us. "I'm the one who set all this up."
"Yes, yes, you did great too, Ravel," I reply, patting her head.
"Hehe~" She giggles, nuzzling into my touch. "Then you wouldn't mind giving me a reward for being such a good girl, right, big bro~"
"Sure, how can I refuse you?" I chuckle, pulling her into a kiss.
The three of us spend the rest of the day together, enjoying each other's company. As far as birthday presents go, I'd say this is one of the best.
