What if . . . . Ultimates & Attack On Hero's

Okay um I guess I'm the watcher, let's see what happens in this What If me and Goosey came up with.

A/n: This is kinda weird so bare with me please

The story of Y/n Jeager is a chaotic one but this one might be his most strange to say the least, a Earth with Y/n on it but in the class that he and his best friend enter meet two individuals. Wanda and Pietro Maximoff, two foreigners to Japan just like Y/n is.

Y/n surprisingly enough took a liking to the two and introduced himself to the two as Izuku stood behind him.

Y/n: Hey, I'm Y/n Jeager Leonhart, this is my friend Izuku. *Sticks out his hand*

Izuku: Um hello.

Pietro: Hey I'm Pietro. *He said giving Y/n a handshake* This right is my twin sister Wanda.

Y/n: You two don't look like twins. *He said confused*

Izuku: *Whispers to Y/n* Not all twins look the same Y/n.

Y/n: Huh? But all those cartoons made it look like all twins are the same. *He said scratching his head*

Wanda: Aren't you too old to be believing in cartoons? *She said slyly*

Y/n: Well we do live in a world filled with people who can destroy buildings with a single sneeze. *He said with a smile*

The two then started talking to each other as Pietro watched them and started to mean mug Y/n a bit before seeing a yellow callapiter thing squirm it's way into the room but soon found out it was their teacher.

Timeskip

It is now the end of the day and we see Y/n, Izuku, and the Maximoff twins heading out together with Y/n still talking to and even flirting a little bit with Wanda. This turn of events was a surprise to Izuku as he watched his friend flirt for the first time but Pietro was fuming and was having a hard time hiding it.

Y/n: And that's how I found my love for ramen.

Wanda: Sounds more like an addiction to be honest. *She said laughing*

Izuku: He once brought in a cup and kettle and tried to boil it in the bathroom in junior high.

Y/n: Dude! *Elbows Izuku*

Izuku: Ow! *He said rubbing his arm*

Wanda: *Giggling* You two act like brothers you know?

Y/n: I guess but we oughta be heading home now. Was nice meeting you two.

Pietro: Feelings mutual let's go Wanda.

Pietro practically dragged his sister away from the two lifelong friends.

Y/n: Huh she was nice, her brother's a bit weird though.

Izuku: You could say that again. But Y/n?

Y/n: Hm?

Izuku: You like Wanda don't you? *He said having a grin*

Y/n: W-What!? I don't have time for women!

Izuku: Oh really huh? Why are you blushing? You totally like her!

Y/n: N-N-No!

This didn't help Y/n's case as his face did indeed get redder from what Izuku said.

Izuku: See you're even getting redder!

Y/n: Shut up before I tell Uraraka about your little special dreams!

Izuku: *Turns crimson* THAT WAS A ONE TIME THING AND YOU HAD A UV LIGHT ON HAND!!!

Y/n: Mom always says to prepare for something to not happen and when it happens make it your bitch.

With The Maximoff Twins

We cut to the two siblings entering their apartment and Wanda plopping down on the couch.

Wanda: Man that school isn't half bad, what'd you think Pietro?

Pietro: Chummy. *He said gritting his teeth*

Wanda: What's gotten you so moody?

Pietro: Nothin just that Leonhart guy being so agh.

Wanda: Are you that jealous?

Pietro: Maybe.

Wanda then got up from the couch and went up towards Pietro grabbing his cheek and cupping it.

Wanda: Want me to make you feel better~?

Pietro: Can we take it to the next level?

A/n: This is making me wanna throw up, but the show must go o- *Fucking dies*

Wanda: Anything for you.

TIMESKIP [1 day before the USJ Incident]

During the time at UA Y/n had excelled in most subjects along with there being battle that put him to the test as Y/n and Wanda were paired up for the battle and had to face Iida and Bakugou in which Y/n took a head on blast from Bakugou that was aimed at his female partner.

Y/n as well during this time got more and more friendly with the Maximoff twins, specifically Wanda but tried to talk to Pietro but seemed like he resented Y/n for some strange reason. Izuku told him that maybe he was being protective because she's his only family apparently but Y/n didn't think it could only be that.

After one day during lunch Y/n and his new pal Shoto were sitting in a less populated area of the lunch room and we're discussing something.

Y/n: Okay do you know why I brought you here?

Shoto: You said you would give me cold soba.

Y/n: Annnnnnd?

Shoto: . . . . . . and that the Maximoff's we're off.

Y/n: Right. Don't they seem too close ya know?

Shoto: Now that you mention it, they always seem to be clinging onto each other.

Y/n: And the copious amount of kisses on the head-

Shoto/Y/n: And the pet names.

They both shiver at the countless amount of times they see the twins interacting almost as if they we're a couple of sorts.

Y/n: I don't want to come off as a weirdo but do your siblings do that to you?

Shoto: Fuyumi just makes me food and Natsuo is gone a lot so no.

Y/n: Damn I guess there's only one way to find out.

Shoto: Make a venn diagram of their family lineage and find out their deepest secrets while also making many conspiracy theories along the way?

Y/n: . . . . . Dude you need to relax. I'll just follow them around nothin too weird.

Shoto: How's that better?

Y/n: What can I say I'm a classic type of man.

After School

Y/n already informed Izuku that he'd be doing 'something' and was seen resting next to a wall blending in with the shadows as he wore his jacket and had his hoodie covering his face.

Y/n: (Let's see if these two really are from Alabama.)

He then saw the two exiting the school while holding onto each other making Y/n's stomach chern at the sight but saw Pietro suddenly pick up Wanda and dashed off in a blur.

Y/n: (Not on my watch bitch.)

He then activated his superhuman quirk and ran off following Pietro's dust trail that was quickly dissipating but Y/n decided to leap into the air and saw Pietro's blur stop at a motel.

Y/n: (Why would they stop there?)

He then landed behind said motel not being noticed by anyone but it didn't help that he made a bit of a crater in the shape of his feet. Y/n quickly dismissed that before turning a corner and saw the twins go towards a room before closing the door.

Y/n: Not adding up at all, swear next thing I need to see is a hentai play out.

He then grabbed his phone and looked through the front window as the blinds weren't really helping that much as Y/n saw the two siblings taking off each other's clothes and then quickly leaping onto the bed.

Y/n: (No friggin 'way.)

He then took pictures before taking a video of the two going at it for 3 minutes before Pietro released all over Wanda's face.

Y/n: (What the hell did I just see!? Like sure Wanda is hot but seriously like her BROTHER!? Oh god what would Uncle Levi do? Man I'm glad I don't have any yandere siblings who are programmed to love me due to genetics.) *He said looking at the 4th wall*

MrSkywalker69: *Coughs*

Y/n: (Okay there's a solution to this maybe I can talk to them about this maybe show them the consequences. Yeah show them that this could jeopardize the freedom- I mean uh the potential child they could have through this.)

Y/n then continued contemplating his decisions before hearing they're bed creaking from inside and saw them going back after 5 minutes.

Y/n: (Ehhh they're like rabbits. Disgusting incest loving rabbits.)

Day of The USJ Trip

Y/n: You gotta be shitting me.

Class 1A was now staring down an army of Villains coming out of portals along with a buff bird looking thing exiting a portal.

Levi: Y/n go an-

He didn't get to finish as Pietro wanting to impress everyone took down all the villains around them before trying to fight the buff bird but was grabbed and had his left leg snapped and then he was thrown through the dome of the USJ.

Shigaraki: Well he's probably dead. Nomu kill them.

Wanda: PIETRO!!

Y/n: Idiot! SHOTO HOLD HIM!!

He then bit down his hand causing lighting to form around him but before he fully transformed Shoto shot ice at Nomu which held it in place as Y/n now in titan form brought down his fist crushing Nomu through the floor.

Y/n then got up from his position and brought his left leg up and performed an axe kick onto Nomu's position. He then brought down a barrage of fists onto the now forming crater as the Nomu wasn't even given a chance to fight back.

Y/n after delivering one more punch decided to do a flashy finisher by picking up the Nomu and dropped it towards his foot and then kicked the with his full force launching the Nomu outta the USJ and into the sky as the being soared through the sky and maybe even entered the atmosphere.

Bakugou: Damn that was uh. *Sniff* That was beautiful.

Later that Day At a Hospital

Pietro was seen on life support as the heart monitor was beeping and Wanda was seen sitting in the room until a knock was heard.

Y/n: How's he doing? *He said walking in*

Wanda: They said he had over 15 broken bones, 20 fractured and that his leg was torn apart. They barely made it to the emergency room with him.

Y/n: That's hardcore even for me. *He said giving a strained chuckle at the end*

Wanda just kept holding Pietro's hand until Y/n sat next to her and looked over at Pietro.

Y/n: Look I uh I know about the whole um how do I put this. Incest thing. *He said quietly*

Wanda: . . . . . . .

Y/n: . . . . . . I didn't tell anyone if you were wondering.

Wanda: . . . . Thank you.

Y/n: It's uh no big deal, just another strange thing to learn about in life I guess.

Wanda: You're not disgusted by it?

Y/n: Oh I definitely was. I even threw up 10 minutes later after finding out, but hey I don't know your lives and you don't know mine so I thought that I'd keep it to myself outta your respect Wanda and privacy as well.

Wanda: That's um wow again thank you Y/n your probably the only guy friend I've ever had this talk to you know besides Pietro.

Y/n: Feelings mutual Wanda. You know they're gonna send you home here soon right?

Wanda: I know.

Y/n: Want me to walk you home?

Wanda: I-I'd like that.

10 Minutes Later

Y/n was seen opening the door to the apartment as Wanda then entered with Y/n looking around.

Y/n: Nice place.

Wanda: Thanks, got it a month ago, so you want to stay or?

Y/n: Sure my parent's honestly don't care, or well my mom doesn't cause she trained me how to kill people since I was 6 so yeah.

Wanda: Sounds hardcore.

Y/n: D-Did you just use my line?

Wanda: What? It's catchy.

Y/n: Well a lot of things are like me.

The two chuckle before Wanda walks towards her room.

Wanda: I'm gonna switch into something more comfortable if you mind.

Y/n: I incest. *He said winking*

Wanda: Alrig- Hey watch it you might be a guest but I can still make a dinosaur eat your head off Jeager.

Y/n: Sure.

She then closed the door as Y/n walked around looking at pictures of the two siblings growing up and this made Y/n wonder how all this incest crap happened.

Y/n: *Mumbling to himself* Did they just start fucking or was it forced? Or did he slip on a banana peel and make his dick fall into he-

Wanda: I can hear you Y/n.

Y/n: AH!

He then turned around holding up his fists but was soon staring at Wanda as her outfit was less than presentable.

Y/n: Uhhh you look um. *Looks at her breasts*

Wanda: My eyes are up here Jeager.

She then grabbed his chin bringing it down to her eye level and bringing his face closer towards her. This just caused the two to be silent as they just stared at each other for a moment before they smashed each other's lips into another causing them to start making out on the spot.

Y/n then grabbed her hips bringing it in close to his own as she wrapped her hands behind his head causing the two to get even more intense as Y/n picked up Wanda with ease and brought her up to a wall were the stopped to catch their breath

Y/n: Thought *huff* you we're only into *huff* you know.

Wanda: Maybe *huff* you can convince me otherwise *huff* Jaeger boy.

He then smirked before attacking her neck by nibbling on it causing Wanda to reel her head back and started grinding her hips against the larger teen who continued his assault on her neck.

This soon ended with Y/n finishing marking his territory before Wanda pulled him back into a kiss and as they continued kissing Y/n led them towards Wanda's bed where he placed her beneath him.

Y/n then shoved his face towards her breasts as he sucked on the top half of it making the brunette moan at his attempts to pleasure her.

Wanda: (H-He's really ac- ah~ active in b-bed.)

She then felt Y/n's growing bulge in his pants causing Wanda to grab and pull them down to see his throbbing 9 incher waiting to be put to good use making Wanda gasp at his size.

Wanda: Y-Y/n?

Y/n: *Stops motorboating her* Hm?

Wanda: Are y-you a virgin?

Y/n: Yeah more or less.

Wanda: Oh- hey wait how do you know how to do half the stuff you've done?

Y/n: I uh *ahem* watch hentai every now and then.

Wanda: Really huh? It's nothing to feel bad about but wouldn't these feel better than some lotion and your hands~? *She said pressing her breasts together*

It took Y/n a second before figuring out what she meant as he laid down and Wanda straddled his waist before leaning down and placing both her breasts over Y/n's manhood and nearly engulfing it but Y/n's tip showed as Wanda proceeded to give a tit job to Y/n moving her breasts up and down and occasionally sucking on the twitching tip.

But unlike her brother Y/n didn't cum so easily so Wanda after putting more effort into the tit job saw precum start leaking causing her to go faster on Y/n's throbbing cock which was now reaching its limit after the 5 minute tit job.

Y/n: I'm gonna cum here so- AHHHHH

He then released all over Wanda's breasts and face for almost a good solid minute before coming to an end.

Y/n: Wasn't *huff* too bad, right?

Wanda: (He just cummed for almost a minute and is asking if that's bad?) That was incredible wonder how that feels inside~

Y/n: Whoa whoa whoa gonna have to stop you right there don't want to risk having kids now.

Wanda: First off condoms are a thing Y/n relax, secondly my brother is unpredictable. I'm always on the pill.

Y/n: I-I uh that's a good point.

We then cut to the good shit as Y/n now had his member aimed at Wanda's now dripping pussy.

Y/n: (Well uh here goes nothin.)

He then started to put his large dick inside of Wanda, who was currently moaning her head off due to Y/n's size and him being 3 times bigger than Pietro's size and was now molding her pussy to his size and length.

Wanda: (Holy shit how's he this big!? Pietro could barely reach towards my walls but Y/n isn't even all the way in and is spreading me thin!!)

Y/n: Huh this is pretty neat you okay Wanda?

Wanda: I-I'm fine Ahhh~ just start moving please.

Y/n then compiled and started thrusting in and out of Wanda who was still adjusting to his size but was getting lost in pleasure while doing so as Y/n thrusted with great power (and responsibility) more than she's used to.

Y/n: (Man who would've thought my first time would be with an incest twin? Crazy how things wor- and oh I'm gonna cum soon let's see how deep I can go.)

He then stood up on the bed and went even faster as he was now holding Wanda and still thrusting in and out of her at now increased rates before finally cumming inside of her with one final slam that caused her to cum alongside him as white liquids started to get pumped into Wanda's cunt forcefully before it started to overflow and leak out as a result of there being so much.

Y/n didn't pull out yet as the warm sensation from his nut made him want to stay inside her along with her now throbbing hot pussy.

Y/n: That *pant* was great Wanda phew you really made me try that's for sure.

Wanda couldn't even respond as all the pleasure short circuited her brain as she was now just laying on Y/n's shoulder while he simply took off his jacket and shirt.

Y/n: Doing all of that made me want a uh what's it called? Oh a blowjob! Think you can do that Wanda?

It took the Scarlet Witch a minute to respond as she now had some sense of thinking in her after Y/n pulverized her pussy.

Wanda: Y-Yeah I ca-can do tha-that~ *She said in a sickly sweet voice*

12 Minutes Later

We see Y/n now sitting down on the bed talking to his mother on his phone.

Y/n: Hey mom I'm fineeEEEE! Yeah just um uh.

Y/n then looks down to see Wanda covered in some of his sperm sucking on his cock with just her mouth while also bobbing her head back and forth.

Y/n: Just hanging out with Wanda, she needed some company after PieTROO~! Was sent to the hospital. *He said trying to contain his moans*

Y/n: No nothings wrong just a bit busy we were watching a shOoooW~~! One of my favorites we can talk about later love you by!! *He said quickly before hanging up*

Y/n: You almost got us caught ya know? But who am I kidding, we're both enjoying this. *He said grabbing her head and shoving his cock deeper in her throat*

Wanda not expecting Y/n to do that started to gag on his enormous cock.

Y/n: But hey I think I can stay over so you have me for the rest of the night.

Wanda could only respond by sucking harder on his cock making Y/n throw his head back in pleasure.

Y/n: Gonna take that as a yes then.

Timeskip

After that fateful night Y/n and Wanda would regularly meet up at her house and fuck reguorusly until night time, this would even happen at Y/n's house where they would have to be quiter but Wanda was surprisingly into that type of stuff.

But this didn't go unnoticed by some as Y/n's parents saw their son going in and out of the house regularly for unknown reasons so they decided to talk to him about it.

Y/n: Headin out!

Annie: Hold on Y/n come take a seat.

Y/n: Um okay.

He then went over towards his mother as he saw her and Eren sitting on the couch making Y/n sit down on a chair near the couch.

Y/n: So uh what's up?

Eren: Well we've noticed that you've been more uh active Y/n and we-

Annie: Who's the girl?

Y/n: *Sweating* Uh what girl?

Annie: The one you've been seeing.

Y/n:

Y/n: How much do you?

Annie: Nothing actually, just wanted to see your reaction, and now that we know what are you doing with her?

Eren: Well come on Annie he's not doing anything bad now is he?

Y/n: I might've lost my virginity to her. *He said quickly and quietly*

Eren just stared in shock before handing 5 dollars to Annie who was smirking.

Eren: Guess you win on that.

Y/n: Were you two betting on me!?

Annie: No it's just a fun activity, or I think it is.

Eren: Her bet was you were gonna lose it in highschool while I said you were going to lose it till marriage.

Y/n: I. I can honestly see you two doing that.

Annie: And with that I have one question. Is she pregnant?

Y/n: No she uses the pill most of the time.

Eren: You use a condom right?

Y/n: . . . . .

Eren: Right???

Y/n: What's a condom?

Eren: . . . . . Nope. *He then gets up and walks out the living room*

Annie: I need to stop your father before he does something retarded, Y/n make sure you use a condom or I wil remove your sex privalges permantly Y/n.

Y/n: Yes Ma'am!!

Massive Timeskip [After The Sports Festival]

After Y/n's deadlock with his childhood rival Bakugou and Izuku Y/n was seen sleeping on a regular bed with his girlfriend Wanda giving him head while the titan shifter slept from his fight earlier that day.

Wanda: (No matter how many times we have sex I'm always surprised at his size.)

But unknown to them the front door was opened by Pietro who was now on crutches and waddled his way into the apartment.

Pietro: Hey Wanda I'm okay now they let me out early due to my healing factor. Ever since getting out I was craving your as-

He then stopped as he saw his sister giving Y/n a blow job at the moment and she stopped looking back in shock before Y/n woke up as well as he finally healed from all his injuries.

Y/n: Huh? Oh hey Wanda keep goin- Oh hey Pietro. *He said cheerly*

The three afterwards were quiet for a minute until Y/n broke the silence with a question.

Y/n: How's the leg?

Pietro: W-Wanda tell m-me this is a dream!?

Y/n: Feels pretty real to me *He said under his breath*

Wanda: Pietro, look what we were doing was wrong and I think that if we continued it would've been horrible if I got pregnant.

Pietro: But why with him!?

Wanda: Well he was there for me when you were in a coma, and Y/n well has a large cock. *She said rubbing Y/n's member*

Y/n: Man that feels good.

Pietro: O-O-Oh okay then. I-I'll just be around i-in my room.

He then limped out but not before looking back and seeing Wanda now hopping on Y/n's waist and moaning before slapping noises ensued from the room as Y/n now was thrusting in and out of her.

Fin I guess
