[Hello, My Sexy Muffins! I am here with a new story, and in this it comes from my sleep-deprived brain! So please enjoy this chapter!]

(No One's POV)

Izuki was sick, this whole week she felt off, then these last two days she has been burning up. Finally, her fever broke, but her mother rushed her straight to the doctor's.

"Please, Doctor, something has happened, my daughter has fangs, claws, and her body has changed!" Came Izuki's mother's voice.

Izuki groaned; her mom was not in the room, but she could hear every word. Everything was so loud. She let out a growl, and soon the doctor came in.

"My God!" He says, and soon he was taking samples of blood, saliva, and so much more.

Izuki was still out of it, but she bit the doctor a couple of times when he was too rough with her. Her mother was panicked, and finally, after 3 days in the ER, it was confirmed. Izuki had a very rare quirk, which only happened one other time.

"It is called the Sex Quirk. Your daughter turned eighteen, and that is when this quirk changed the one other person." The Doctor explained. "This Qurik is a medical mystery, and it is very powerful. I had to alert the top heroes of this because your daughter has great potential."

"Will she be okay?" Her mom asks.

"She will be fine. Right now, she is having growing pains from the changes to her body. She will be able to go to school come Monday morning. I suggest she become a hero; it will be the best way for her to learn to control her powers."

With that, she was left at home, and for the next two days, all Izuki did was sleep and eat a ton of food.

-Monday Morning-

"Are you sure you are ready to go back to school, sweetie?" Her mom asks. "You can stay home."

"I feel great, Mom!" Izuki says, flashing a fang-tooth smile. "I can finally become a hero!"

She left for school, and she could not wait to see the look on Kacchan's face.

On her way to school, she saw a villain who was assaulting a girl. She saw red, she walked up to him and punched him in the face. Then touched his cheek.

"You will stop what you are doing and wait for the police." She says.

She stayed there, and the police were shocked. "You are just a student." They say. "How did you stop him?"

"I just did." She laughs, the news was there, and she did not notice they caught everything.

-Meanwhile in class-

"Alright, class, I have some shocking news to share with you all." The Teacher says. "Your Classmate, Izuki, has developed a quirk. She will look different when she comes in, also she secretes pheromones that make her more likable. You are not to have sex with her."

"What the fuck do you mean she got a quirk!?" Bakugo demands.

"It is called the sex quirk; it only ever happens in one other person. It does not come out until the age of 18. Izuki was not Quirkless after all; she was just a late bloomer."

The door slides open and everyone's eyes lay on Izuki, getting her quirk made her hair grow out, her body become more curvy and thicc, and cleared up any acne. She looked like a model. Also, she had a succubus tail, sharp nails that could turn into claws, and bright white fangs. Not to mention pointy ears like an elf.

"Sorry, I am late, Sensie. A man was assaulting a girl, and I had to stop him." She says with a bow.

"HOLY SHIT! DEKU IS HOT NOW!" A boy shouts, and Izuki blushes, looking away.

"You can take your seat, Izuki." The teacher says, blushing, she was a 10 of 10. Also... She is legal now...

She walked in and sat behind Bakugo, who was staring at her. He ALWAYS had a crush on Deku, but she was now a total babe.

Class started, and Izuki was finally excited for school.

"Anyways, it is time to start applying to the universities you want to go to!" The teacher says. "I could hand out a bunch of career assessments, but I know what you all want. You all are going the hero route! But remember to get into a good Hero University course, you still have to have good grades. Which, honestly, most of you are all lacking."

"Ha!" Bakugo laughs. "Do not lump me together with all these rejects, teach. I got the grades and the Qurik to get into UA University."

"Yes, you do." The Teacher said, and Bakugo smirked. "But you do have competition now."

"What!?" He demands.

"Izuki wants to go there too, and with her rare qurik, I already have the facility asking me to push their University on her. In fact, every Hero University in the country wants her to attend."

"Really?" Izuki asks with her eyes wide. UA wanted her?

"The FUCK!" Bakugo snaps. "She just fucking got her Qurik and they want her!"

Bakugo turns around, ready to blast the stupid Deku off the planet. But he froze when he saw her, fuck! Why does she have to look so cute!?

"YOU- YOU BETTER NOT THINK YOU ARE BETTER THAN ME, DEKU!" Bakugo snaps, and then classes continue.

Izuki could not stop grinning. She actually has UA wanting her to be a hero! This day could not get better!

[YASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS another chapter is done! I hope you all enjoyed this, and stay sexy, all of my sexy muffins!]

Chapter Text

[Hello, My Sexy Muffins! I am back with a new chapter! This one has Izuki getting overwhelmed by all the attention she is getting. Please enjoy this!]

(Content Warning: Slight NSFW, mainly just humping each other and making out, no actual full-on nudity or sex. Thank you!)

(How Her Powers Work and How She Looks:

1: She can grow her talons like claws out from her hand, which grow up to three feet long, and she can shoot them from her hands.

2: She has fangs, a tail, cat-like slit eyes that glow in the dark, and can see in the dark, point elf-like ears that have super hearing when she focuses, she can grow a pair of wings from her back for flight, they are like giant bat demon wings, and she sometimes grows horns in her head.

3: She has a suggestive touch; having skin-to-skin contact with someone, she can influence them to do what she tells them, and they become eager to please.

4: She has pheromones that naturally attract people, and her saliva is like a drug that, with too many kisses, can make the person she kisses addicted to her. Same with her vaginal juices, it is very addictive, and too much in a short period of time can make the person addicted.

5: She has regeneration, but it slows down if she does not have sex.

6: She is stronger, faster, and more durable.

7: Draw back, she needs to have sex, otherwise she gets very weak and heals much slower.

8: Another drawback back she becomes horny against her will (Hypersexual/Nymphomania), and this can only be taken care of by having orgasm, and it is taken care of when she feeds off someone during sex, and not just her own pleasure.

9: Feeding on sex is th stamina of the person she is feeding off. (She does not need to feed on sex so much if she eats like an insane amount of food)

10: But her feeding off them makes them feel very euphoric, and they get loopy with how good they feel. The Stronger the person is, the slower they become loopy.)

(No One's POV)

Izuki was packing up her bags at the end of the day, and suddenly she was more or less swarmed by the students in her class! She did not know how to process all this unwanted attention; she was certainly not used to it. That is when Bakugo stepped in and told all the extras to back the fuck off and leave his nerd alone. It took him threatening to blast them to get them to leave her alone. She turned to look at Bakugo with a small smile. She was grateful that he went out of his way to save her from a group like that!

"Thank you for that, Kacchan!" She thanked him with a smile and felt weird, like all his feelings for her were trying to calm down at once!

"I did not do it for you! Just did not want to listen to those horny fucks!" He snaps.

"Well, thank you, anyways." She tells him with a kind smile. "I have to get home; Mom is worried enough about my new Quirk."

"Tch, whatever, nerd." He says, and she leaves the room, heading out of the school and making her way home.

She was going to be a hero soon, and she could not wait!

"Hmmmmm~ Who are you sexy little thing~?" She heard from behind her.

She froze. That was a creepy, slimy ass voice. She jumped back away from the voice and looked to see who it was.

It was some type of Sludge Villain.

"You smell and look good~" He says with a smirk. "I am going to get my hands on you~"

Izuki looks at him. "Ew..." she whispers, and suddenly the sludge Villain jumps on her and starts to push his way under her clothes. "AH! No, don't touch me there!" She shouts.

She could feel the sludge villain stroking her body, and it was triggering the downside of her Qurik... She was getting so turned on...

"Mmmm~ Stop~" She whines.

"Such a naughty and slutty little woman~" The Sludge Villain laughs at her.

She was not able to focus when suddenly she heard the voice that she could always recognize. It was All Might! He tore the Villain off of her, and she fell to the ground. She was panting and horny. Her body did not know how to deal with this intense arousal.

"Are yo-" He knelt down next to her, and she growled, grabbing All Might and pulling him down into a kiss.

She did not know why she did it, but she needed to kiss him. He was shocked and went to push her away. He has not kissed a lot of people, but kissing her~ It felt so fucking right.

Izuki moaned into the kiss and pulled All Might on top of her. She did not know why she was doing this, but she needed to make this horny feeling stop. All Might pushed his knee up her skirt, and she cried out as her soaked panties got pressed by his knee.

"All Might~" She moans as he starts to kiss and bite down on her neck.

He felt like he was a man on a drug, kissing her made him feel so fucking good~ "Sweet~" He moans and moved his knee and pressed his bulge up against her. They grind against each other.

Both of them were virgins, so it did not take long for them to both cum. After they both came down from their orgasms, their minds slowly became clear.

"A-All Might?" Izuki asks, shocked. She did not just make out and hump him until she came against him. "I-I am s-so s-so-sorry!" She was so flustered that she could not understand why she lost control and did THAT!

"No! It is okay! I am sorry!" He tells her and gets off her. "I am so sorry, here let me take you."

He picked her up and flew to a building with her, unaware that the Sludge Villain slipped from his pants.

(All Might's POV)

I set her down, and she would not look me in the eye.

"I am sorry again for doing that, ma'am." I apologize to her.

"N-No, it is my fault, I have a sex quirk and I just got it..." She whispers her face is a bright red. "I did not know how intense it would be..."

I look at her, really look at her, she was beautiful with her curly green hair and bright eyes. She is so stunning.

"What is your name?" I ask her.

I know I should not waste my time doing this, but I wanted to get to know her; I could not help myself.

"Izuki, Izuki Midoryia." She tells me, meeting my eyes.

"It is nice to meet you, Izuki!" I say and smile at her. "I am sure you are going to make a great hero!"

I gave her a thumbs up, and she smiled and started to ask me questions. I could and realize I am losing time, but I could not walk away from her.

She flashed me a smile, and then my body deflated, and she blinked. "Huh?" she asks, confused.

I wish she had not seen me in this weakened state. I have no choice but to tell her the truth now.

A part of me was happy I could be honest with her. I do not know why, but I want to spend so much time with her. I cannot help it.

[Hello, My Sexy Muffins! I am back with a new chapter! This one has All Might telling Izumi of his injuries! Anyways, please enjoy this chapter here!]

(No One's POV)

(Name) Blushed. "How can this be! You went from buff man! To Sickly twink!?" She panicked, and all Might blushed as she was so confused and still told him that she found him to be still attractive.

"Hey, miss, please calm down." All Might tells her and grabs her shoulders, and she looks up at him.

"You know how guys at the pool are always suckin' in and flexin' and tryin' to look buff? I'm like that." He tells her. "This is my Civilian form, the buff for is me when I am using my Quirk."

"Ah!" she says and looks up at me. "That makes sense... I think?" She still seemed confused about it. "But you seem like you could not control it. Is something wrong?"

"I'm counting on you to keep your mouth shut. Don't go talking about this online or telling your friends." All Might tells her and pulls his shirt up, revealing a large wound on his chest.

"Oh My God!" She said and gently touched it. All Might blushed.

"Pretty gross, right? I got this in a big fight five years back. My respiratory system was basically destroyed. I lost my whole stomach. All the surgeries have pretty much worn me out, and it can't be fixed. Right now, I can only do hero work for about three hours a day. The rest of the time, this is what I look like." He tells her.

She looked up at him with wide eyes. "Five years ago? So does that mean it was the fight with Toxic Chainsaw?

He looked at her, shocked. "Wow, you know your stuff. But no. The punk may have landed some hits, but he couldn't bring me down." He tells her. "Most of the world has never heard of this fight. I did everything I could to keep it under wraps. I'm supposed to be the guy who's always smiling, right? I'm the symbol of peace. People everywhere have to think that I'm never afraid. But honestly, I smile to hide the fear inside. It's just a brave face I put on when the pressure is high. This job isn't easy."

She nods her head. "I know, but this is why we need heroes." She tells him. "If no one would stand up for those in danger, then the Villains will win."

All Might smiles. "That is right, you will make an amazing hero, once you are trained up."

She smiled and nodded her head. "Thank you! I won't keep you any longer! Thank you, All Might! It was amazing meeting you! I promise I will keep your secret!"

He nodded his head and gave her a thumbs-up as he left. Time to take that Villain to the police.

Izumi smiled to herself. All Might, her hero, said that she could be a hero! She cannot wait to apply to U.A. now!

She cannot wait to be a hero! She heard an explosion. "Is that a villain! I wonder what hero is going to stop them! I can take more notes!" She gushed.

She was unaware that it was the sludge Villain and she had attacked her Kacchan!

Chapter Text

[Hello, My Sexy Muffins! I am back with a new chapter! This one has Izuki trying to save Kacchan, so good luck, please enjoy this chapter here!]

(No One's POV)

Izuki had made it down to the area, and she was shocked to see that no heroes were able to do anything. Worse of all this was the same Sludge Villain that had been caught by All Might! That means- She accidentally caused the Sludge Villain to fall from All Might when she clung to him! Meaning that everyone who is hurt, or will be hurt by him... is because she did this! She felt hot tears well up in her eyes. What can she do? She is not a hero yet, and she does not know how to use her quirk! What could sh-

"GET THE HELL OFF ME!" She heard the familiar voice of her friend cry out, and she did not know what she was doing, not before she was doing it!

Her body moved before she could think. It ran over to Kacchan, and she transformed fully, wings, tail, claws, fangs, and so much more power within her!

"Oh my god!"

"Who is she!"

"What type of quirk is that!"

She snarled. "LET HIM GO!" She slashed right down the Sludge Villain.

She was ripping and slashing chunks of the Villain off. It was brutal, but the Sludge Villain kept reattaching itself.

"YOU SCUM!" She snarls and outright bites him. "LET KACCHAN GO!"

All Might watched her work and watched as the Villain tried to fight against her. She was clearly new to her quirk and did not know how to use it at all; she was fighting solely on instinct. But she moved like a hero, she fought like a hero, and was continuing to fight like her life depended on saving this young man. So All Might came into the fight and helped her and the young man. She was held firmly against him, and then he even changed the weather with his power.

Izuki looked up at him. He saved the day when she could not; she was thankful to him, but she knew he pushed himself past his limits!

Was there some way she could help him?

(Bonus power maybe? ;3)

It was done, and Izuki was praised for her bravery, but also scolded for being reckless and not listening to the pros. She had to admit she did not have a plan when she ran in. She wanted to talk to All Might and thank him, but she was not able to get near him.

She was also still embarrassed that her first sexual experience as an adult was to do that stuff with All Might. She was so embarrassed at what she did!

She made her way home, only for Kacchan to tell her that he did not need her help, that he would never need her help! She sighed; she was just glad that he was okay. She continued to walk home, only for All Might to be standing there!

"I AM HERE!" He cries out and flexes.

"Ah!" She jumped and calmed down. "I am glad you are okay! I was worried about you for a sec!"

"Yes, I am actually feeling a lot better than I normally do!" He laughs. "I wanted to thank you."

"Thank me?" She asks him.

"Yes, I have been forgetting what it means to be a hero, and you, Miss Izuki, have reminded me of that. A hero acts the way you did today. Your feet moved your body into action before you could think, right?"

She nodded her head. "Yeah, all I knew was my body moving forward and then my brain told me I had to save him!" She confessed.

"So many true and great heroes had the same feeling in their lives, which is why I have chosen you."

She blinks, confused. "Chosen me?" She asks.

"Yes, you see, my Quirk can be passed on, all its strength and power can be passed on from one hero to the next, it is called One For All. I want you to be the next symbol of peace!" He tells her and offers her hand to Izuki. "What do you say, Izuki Midoryia!"

She was inwardly panicking about how a quirk like this could work and how it could be passed down, but she was honored that All Might chose her! She takes his hand.

"I will do it!" She tells him.

They were both unaware that All Might was easily staying in his muscle form longer than he should be able to...

(OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOHHHHHHHHHHHHH)

[YASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS, another chapter is done, and the plot twist, maybe? I hope you all enjoyed this, and stay sexy, all of my sexy muffins!]

Chapter Text

[Hello, My Sexy Muffins! I AM BACK, and I hope that you all enjoy this chapter here, muffins!

DISCLAIMER: I am changing Izuki's name to Izumi. I just like it better, so please be mindful of that!]

(No One's POV)

Izumi woke up, and she yawned. She felt so much better after yesterday; she feels faster, stronger, and just filled with more energy! She feels like she could take on the world! She jumped out of bed and got dressed, today was saturday and she was meeting All Might. She is so pumped that she cannot wait to finally become a true hero! She is even going to study even harder because she now has a chance of getting into UA University!

"Life is going great!" She cheers and her tail was swaying back and forth.

She made it into the kitchen and saw her Mom making breakfast. It has just been her and her mom. Her dad left them, and she divorced him. Then she met a new guy, whom she married when Izumi was five years old. She has not seen him in five years, but she would still talk on the phone with her stepdad.

"Izumi Zen wants to talk to you." Her mom called, and she took the phone from her mom.

"Hiya." She says in a chipper voice.

"Good morning, Zumi." He used the nickname he had for her. "So your mother had told me about your Qurik."

"Yeah... it is a lot to take in," Izumi admits.

"I called for the doctor to keep an eye on you and your changes. You will have regular exams." He tells her.

"Zen..." She groaned out. "I am fine, it is just a quirk, most of the population gets them."

"Not the way you did, Izumi." He used her real first name. "Also, I do not want you to become a hero."

"What?" She asks.

"When you had no Qurik, there was almost no chance you would get one. I do not want you hurt." He was stressing his voice in a way she had not heard before. "You will not end up like that Meat Head All Might."

Izumi gripped the phone tighter. "All Might is an amazing hero." She tells her stepfather. "Y-You also have not been here in years, you left mom, and I am not going to let you tell me how to live my life. Have a nice day!"

She hung u,p and Inko looked at her daughter. "Sweetie, what did Zen say?" She asks.

"I don't want to talk about it, Mom, sorry... I got to go." She tells her mom and grabs her coat, running out the door.

Izumi made it to the beach where All Might was waiting for her. It had a literal dump on it. What was this place?

"All Right!" He cheers. "YOU ARE HERE!"

She smiles, feeling better already. "Yes, I am!" She cheers back. "Sorry, my stepfather called and wanted to talk to me."

"I see, I hope you are not in trouble." He says.

"Nah, just him being a parent." She laughs.

"So what is this stuff?" She asks.

"You see the way the currents around her are, people throw their garbage into the ocean, and it gets brought here. Then it ends up making a landfill out of the beach. People forget that being a hero means helping those without being asked and not always for fame or glory, but to help when it is even thankless work." He explained to her. "So, to prepare your body for my quirk! As it will tear your limbs off if you are not ready! You will clear this section of the beach by the time the UA University Entrance Exam comes along!"

Her eyes widen and she looked at all of this stuff. "Is that even possible!?" She questions, shocked.

"It is! You will be working out your body, transforming it into a woman who can handle this quirk!" He cheered, and she was getting pumped as well; she realized she was really strong. Stronger than she thought she was.

All Might noticed this, too; she was carrying things with ease that she should have been struggling with. Was this a part of her quirk?

[YASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS another chapter is done! I hope you all enjoyed this, and stay sexy, all of my sexy muffins!]
