All For All(BNHA)

(SI x Kyoka Jiro with a side of incest)

---------------------------------------------------------------------------------------------------------------

When someone is self-inserted into a fictional world, it'll either end up really good or really bad for them. Luckily, it seems to be the former for me.

How do I know this?

Simple, my Quirk awesome!

My Quirk is…

"Ah… A-Ah… Hah… Kenji… s-stop it… Ahh… you're goin-aah be late…" ?

"Sure thing mom," I reply, casually playing with her hardened nipples while I'm still pounding her from behind.

"Nngghh!" She bites her teeth trying to hold back a loud moan.

"I'm close, where do you want it today mom?" I ask as I'm reaching my limit. Her pussy tightened in anticipation after hearing me.

"My mouth. Today's not a safe day." She said sounding reluctant.

"Sure thing." I lift one of her legs to turn her around all the while still pounding her. Once she's facing me, I took my dick out. She didn't waste any time to get on her knee and starts to suck my dick that just came out of her pussy, still covered in her juice.

In just a few seconds of her skillful work. I release the load I've been holding back straight into her mouth, holding it there to make sure she swallows it all. She pulls back after swallowing the last of my cum, dusting her and straightening her clothes.

"Geez, you should stop doing this in the morning especially today when you have an exam coming up," she complains without any negative emotion to back it up. At this point, she's just saying it for the sake of saying it.

"I can't help it. I don't want to go to the test with a hard-on and my sexy mom was in front of me."

"Hmph, you and your sweet words. You're going to leave so many girls with a broken heart." She said in mock disappointment.

"I would never," I said showing a fake surprise at her words. "I would never leave any girls that fall for me behind. They are all going to be in my future Harem!" I declare.

"Then I guess I will be looking forward to getting many daughters." she plays along.

"Don't you mean sisters?" I ask pulling her closer until her face is right next to mine.

She blushes and looks away, "Get going before you're late."

"Sure thing." I pull her in for a kiss, not bothering about what she was doing with her mouth before.

"Love you mom, see you later." I wave my hand in a circle causing a portal to appear before stepping through.

I appear in an alleyway before checking to see if anyone saw me. Seeing no one around, I make my way toward U.A. for the entrance exam.

As I was saying before, my Quirk is officially known as Quirk Share, which I nickname All for All. It allows me to use the Quirks of those I 'bonded' with and allow those closest to me to use the Quirks I have. There are many restrictions like the bond can't be one-sided, both parties have to at least consider each other friends, I have to train the Quirk I get from scratch, and many other suck restriction.

Noticed how I said "officially"? Those are just the things I told people and what they observed. In truth, my Quirk is a bit more sinister than that… ok, it's a lot more sinister.

My Quirk works in 3 stages. First, I have to mark people. As long as I'm touching someone, I can mark them. Unless the person I'm trying to mark is wearing clothes 3 inches thick, I can mark them even through their clothes.

Once they are marked, the second stage begins. The second stage has two parts. The first part is as I said before, I'm able to use the Quirks of those who I "bonded" with. Basically marked someone and I'll be also to use their quirk.

The second and more sinister part of my Quirk is that it will influence the mind of the person I marked. It's subtle, only making them see me as interesting or make me stand out in their eyes but as time goes on, those feelings will be amplified depending on how I want it to. Within a week, I can make a person who hated my gut into my most loyal minion.

No one will notice either when they are fully loyal to me, they'll still be themselves except with a twist. When I order them to do something, they'll do it as if it's a normal thing to do and if it's not an order, they'll still try it if they have time.

It's not perfect though, someone with strong willpower can resist the effect of the mark even if they don't know about it. For example, I managed to mark All Might in one of his events where he was signing autographs and giving out handshakes. He must have an unbreakable will because all it did was make him see as more interesting than other kids when I met him again a few years later.

In contrast, most people I marked I got under my control in just a week. Even the Heroes I marked didn't take that long to fall under my control. The one that took the longest is one year and that's because he's a stubborn guy without many friends.

Oops, I'm getting off track.

Anyway, the last stage of my Quirk and the reason I nickname it All For All is that once someone is no longer able to betray me, they get access to the Quirks I collected through the mark. Sure they'll still have to train the Quirk they want to use but they'll get to use more than one Quirk like me. There's no risk either because the Quirks will just be "Shared" not copy or stolen and put into one body. That means there won't be anyone breaking down or exploding due to having multiple Quirks.

Oh and if you're wondering about my mom, well, she a sexy woman living by herself and I'm a horny teen boy. It didn't take long for me to break down her morals and make her mine with my Quirk. To me she was never my mom, I left my real mom behind when I died and end up here. To me, she's just a smoking hot woman that I grew up with and now she's my smoking hot woman. MILF and all that.

'Now who to mark next.' I thought as I look out into the field of wannabe heroes. As I look around, I spotted someone familiar.

'Earphone Jack girl Kyoka Jiro.' I couldn't help but smile widely. She's one of my top 3 girls when I was watching the show. Now that I'm actually here…

"Hi, I'm Osaki Kenji." I introduce myself and held out my hand. She looks at me than my hand then me questioningly.

"Kyoka Jiro." She introduces herself and hastily shakes my hand. My smile widens as I feel my Quirk doing its work.

"I'm curious. You don't seem to have an offensive Quirk or one that helps with fighting. Are you sure it's ok to be taking this test?" I ask as an excuse. Normally people will be either annoyed or become even more cautious and distance themselves when someone they don't know asks this type of question but thanks to my Quirk. She'll see me as a concerned stranger looking out for her.

"You don't have to worry about me. I think I can handle myself well enough even without a powerful Quirk." She replies with a soft smile, her previous caution gone like it was never there.

"If you say so but if you need help, don't hesitate to ask." I pretend to still be a little worried, "We are training to be heroes after, not miracle workers."

"Sure…"

"AND BEGIN!" Everyone hears Present Mic shout from the distance.

"If you can keep up that is." She said before running off into the city.

'Oh right, she likes to take jabs at people. Almost forgot about that, it has been a while….'

"WHAT WRONG? THE TEST HAVE STARTED! RUN RUN RUN!" Present Mic shout again breaking me out of my thoughts. By then Jiro already found her first robot.

'So it's a challenge huh?' I put my hand on the light pole near me.

"Disintegrate." I activate one of my many Quirks. This one will break down any material I touch into small sand size pieces. It doesn't work on humans.

I wave my hand over the metal sand that formed from the broken down light pole and activates another one of my Quirk. Magnetism, allow me to control small pieces of metals. The metals can't be any bigger than a 1-inch diameter sphere but the limit to the amount I can control is very high. I can use it to move about 1 ton of metal sands right now. It's my favorite Quirk so far.

I move some metal sand under me and condense them together so much that they look like a metal plate. Once the plate is formed, I fly off into the city with the rest of the metal send following me. As I passed by Jiro who just finished destroying the robot with sound, I see a robot ahead and send the metal sand at it.

As the metal sand goes toward the robot, they group up together into 3 separate piles before coming together into a makeshift cone spear. The spear then enters through the robot's chest before breaking apart and condensing together again. As I pull the sands out, parts and wires stuck to the metal sand come out with it effectively killing the robot down.

I turn back and smirked at her surprised face. It didn't take more than a second for me to take out the robot.

"Keep up if you can." I taunt before flying off to look for more robots.

I fly ahead and destroy any robot I come across while saving anyone I can find. Gotta look good to the audience and all that. At some point in the exam I realize that while it might look cool, I'm wasting unnecessary energy trying to break the robot so I change my strategy. Instead of breaking into the robot, I surround them and let the metal sand slip through the cracks before breaking enough wire to kill the robot.

It's a lot more energy efficient but it takes more time. It takes 1 second longer than usual to be exact.

In the end, I even managed to take out the zero-pointer when everyone else was running away from it. Best of all, I manage to get Jiro's number before we leave.

A week later I got the results back from U.A. 68 villain points and 27 rescue points putting me in first place with 95 points total. I would have gotten more points but I was distracted by the giant robot I was trying to take out. They even send a video with All Might saying that they were impressed I managed to take out the zero-pointer when they never expect any student to be capable of it.

I took out my phone and call Jiro. I said call but call in this time period means video chat.

"Did you get your test result yet?" I ask after she picks up.

"Yes! And I passed!" She replies in excitement.

"That's great! I passed too."

"Of course you did. With how many robots you took out, I'll be surprised if you didn't pass."

"Hey, why don't we go on a date to celebrate?"

She blushed but still rely "Sure, I'm looking forward to it. Same place?"

"Yeah, meet you there in 2 hours."

We hang up after deciding the time and place for our date. This isn't the first date we have, it's actually the fourth in just a week.

Another thing about my quirk is that it works faster when I'm in physical contact. It takes about a week to fully affect a normal person but if I remain in contact with them, it'll take no more than a day. Still, even with 3 dates and with me taking as many chances to be in physical contact with her as I can, we haven't gone further than a kiss. I plan to bring her home today.

---------------------------------------------------------------------------------------------------------------

Three hours later we're back in my room desperately kissing each other. Halfway into the date, I give her a peck on the lips. She returns the favor and kisses me back and before long we were making out in public barely able to get go of each other. I only managed to break the kiss long enough to invite her home. When she agrees, I grab her hand and run which leads to now.

As our tongues are busy wrapping around and tasting each other, I pull off her leather jacket and push her toward my bed. Her hand didn't stay idle either finding and unbuttoning all the buttons on my shirt before taking it off leaving me without a top. I return the favor pulling her pink dress loose dropping it to the floor.

She bumped into the edge of the bed and I fall down on top of her all the while not breaking the kiss. I reach behind her and unhook her bra. As I start to pull her bra down, I slowly follow along with a trail of kisses. First the bottom part of her lips, then her chin, followed by her neck, stopping to enjoy myself a bit more before going down her shoulder and finally toward her small yet perky breast. Before I can get to her breast though she quickly covers it with her hands.

I look up to see her blushing red, "Sorry they're so small." she said sounding disappointed in her small breast.

"Don't be," I went back and kiss her on her lips.

"They pretty and cute just like you are." I kiss her again and put my hand over her. She blushed harder at the words but didn't resist as I pull her hands away. I went back down toward her breast to continue my work, kissing along stopping to play with her nipples.

"Ahh…" She moans as I bite into them softly, one hand playing with her other nipple and the other making its way lower. I rub her thigh, slowly making my way upward before feeling something wet. Even with her leggings and panties in the way, I can still feel the wetness as I get closer to her entrance.

"Aahh…" she moans again when I finally touch it even if it's above her clothes.

I then slid my hand inside her leggings and panties, moving my hand down until it's on the edge. I slowly move my fingers around her entrance, teasing it yet not going any further. It wasn't until I can see a pleading look on her face that my hand 'accidentally' slip and my index finger ends up inside her.

"Aahh…" She let out another sweet moan.

I move to kiss her on the lips again, one hand still playing with her perky breast and the other messing with her wet pussy. Once in a while, my thumb will brush by her clit making her moan into my mouth. I continue to play with her, skillfully bringing her to the edge yet not letting her go over. A few minutes later I slip another finger into her pussy.

"Mmmm!" not even a second later she have her first orgasm. My hand already behind her head, not allowing her to break off the kiss and her scream of pleasure muffled by my mouth. Only when her shaking die down a little, did I back off leaving her weak and breathless on the bed.

"That… was amazing." She said after catching her breath.

"And it only gets better from here." I pull down her legging along with her panties.

"Wait!" she yells, quickly covering her exposed pussy with her hand. "You did all the work. I want to return the favor."

Since she said so I back off and let her do what she wants. She stands up and made me sit on the bed. She unbuttoned and pull down my pants and underwear making the mistake of putting her face too close in her haste. As my hard dick is free from its confine, the first thing it did was slap her in the face.

I chuckle and she sends me a glare before she looks down and her eyes widen.

"So big…" She said in surprise. She hesitates but still reaches out to touch it.

"And hot…" she stroke it clumsily before using her other hand to help since her small hand can't fit around the whole thing.

"Why don't you try licking it," I suggest. She looks up at me as if asking if she really needs to.

"Try it, if you don't like it you can stop."

She nodded and bring her face closer to my dick. She sticks out her tongue and licks it one… than twice… then three times before deciding to use her tongue to explore the rest of my dick.

She went from the top to the side before going to the bottom then back to the top again and once she have my whole shaft covered in her saliva, she went back to the tip and slowly try to take it into her mouth. Except her small untrain mouth can barely take the head before it starts to hurt and she have to pull back.

She rubs her jaws and complains, "God, how can the women in those videos do that. Just a few seconds and my jaw is already hurting."

"Oh, so you have been watching porn?" I tease.

She turns bright red but didn't deny it, she probably didn't mean to say that out loud.

"Why don't we move on then." I pick her up and toss her on the bed. "After all, you'll have many opportunities to try again in the future."

"Try again?" She asks turning redder.

'It amazing how she's more embarrassed about doing this again than doing it now.' I thought.

"Of course." I crawl on top of her. "If we go through with this, you be my woman and I don't intend to let my woman go," I told her truthfully.

She didn't even think about what I just said, when she heard that I don't intend to let her go, something seems to click inside her and she pulls me down in a deep kiss. She pushes me back again after a few seconds.

"Make me yours" she request.

I cup the side of her face, "Gladly," I said, tapping her head with my middle finger. It activates a quirk that I got when I was curious and visited a brothel. In all my time searching, this is the only quirk that's even remotely related to sex. It'll numb a person's pain and turn it into pleasure. I'm not proficient enough to fully get rid of her pain but she won't feel anything more than a bug bite.

"Relax and pay attention to me." Even if the pain is lessened, the mind can still play tricks on you and make it hurt more than it should. I look her in the eyes.

"Relax your body, I'll take it from here." I rub the entrance of her pussy with my dick, making sure it's still wet. Once I'm sure, I pointed the tip at her hole and slowly enter. She winced and I stopped. I waited for her to relax before continuing. Once I feel the resistance fade, I stop.

"You ok?" I ask

"Yeah, it doesn't hurt as bad as I thought."

"Good, then I'm going to start moving," I told and start moving forward again.

"Ah." She moans in surprise as I hit the end of her tunnel.

"Ahhh…" her moan drag on as I move back out.

"Ah. Nnnf. A-a-ahhmmn. Ah. Ah. Nnhg." She moans in a song of pleasure as I move slowly inside her, content to let her enjoy her first time as much as she can.

It wasn't I feel her heated gaze on me telling me to go faster than I comply. Soon the room filled with sounds of pleasure as we lose ourselves in each other's embrace. One moment we're facing each other kissing to our heart's content than the next thing we know, she down on all four as I pounded her from behind. A while later she'll be up again, her back to me as we try to kiss in an awkward position and yet it didn't stop us. Moments later, I'll be on the bed and she'll be riding me.

When she's on top of me, riding me in a cowgirl position, I'm already reaching my limits. Since I'm close, I move my hand from her hips to her breast. As I found her weak spot from my playing around before, I didn't waste any time and pinch her nipples.

"AAHHHH!" She screams as she climax. Her recently virgin pussy squeeze down on me pushing me over the edge. I didn't bother taking my dick out and instead push deeper feeling the entrance of her cervix losing and cumming right into her baby room.

When she feels my cum inside her, her scream also got louder as her orgasm gets stronger. Her pussy clamps down even harder as if it's trying to milk everything from me. I let go, not holding anything back and fill her baby room completely in white causing my white seed mixed with her juice and leftover blood to flow out of the gap between her pussy and my dick.

She collapses on me, still quivering from her orgasm with her eyes closed in blessed, her body glows briefly before returning to normal.

I sigh, she can't go anymore and I'm still hard. Doing it everyday with mom cause my stamina and libido to be higher than most.

As I was thinking about mom, I look toward the door wondering about her in her room across from mine and yet, my door is not fully closed. A pair of eyes full of lust stare back at me as I look through the door. I smile looking at the same eyes I saw every day in the morning and night.

I push Jiro onto the bed and gesture for mom to come in. She walks in, fully naked with her juice leaking down her leg.

"Come clean this up," I order. Her face lit up as she does as she's told. I'm not worried about Jiro waking up and finding out, the mark already reached the third stage and nothing is going to change that.

I grab my phone and do a voice one call to Jiro's parent. Once it goes through, I give it to mom and pointed at Jiro. She gets what I mean and swallows my leftover cum before talking to Jiro parents, telling them that she'll stay the night.

She closes the phone and went back to sucking my dick. I look at Jiro, I want her to wake up soon. We'll be going all night.
