My Futa Academia

Izuku yawned softly as the sunlight shone on his face. He stretched his arms as he got out of bed, letting the blanket fall off of his curvy, naked body. He put on his socks and ran into the kitchen, sitting down for the bountiful breakfast that had already been prepared for him.

''Good morning Izuku. Did you sleep well today?'' His mother, Inko, asked as she entered the kitchen.

''Yup! I'm ready for another day at school!'' Izuku said excited, his mouth still half-full. Inko smiled.

''That's good to hear, honey. Speaking of which, you should probably hurry. The bus will be here any minute now.'' She reminded him.

''Right! I'll get ready!'' Izuku said as he gulped down the last of his breakfast and ran to the door. He quickly put on his shoes and his backpack before opening the door, ready to head out.

''Aren't you forgetting something, dear?'' Inko asked as she looked at the girly naked boy standing in the doorway, wearing nothing but some socks, shoes and his backpack. The big butted boy looked at her confused, trying to remember whatever he might have forgotten.

''…Oh! That's right! My ring gag!'' Izuku piped up before running to the table besides the coatrack and grabbing a leather belt with a large metal ring attached to it.

''Fhanks mhum!'' Izuku said, his voice muffled by the gag as he clumsily put it on. Inko smiled as she waved him goodbye, getting a nice view of his large girly butt as it bounced with every step he took. Truly, she had fed him well. Izuku ran up to the bus parked in front of the house's porch and got on. He turned to look around the already mostly full bus, seeing his other classmates all in their uniforms as well. The U.A. High School student uniform for girls consisted of a long-sleeve, button-up white shirt, a gray jacket with blue-green stripes, a red tie and a dark blue-green pleated skirt. The boys uniform consisted of nothing more than a red leather ring gag, and the requirement that the boys wear nothing else except their shoes and socks.

The ring gag had to be worn at all times. The only times the boys were allowed to take it off was during lunchbreak or P.E. Class. The ring was implemented to ensure that boys wouldn't speak out of line during class, and to enable easy access to their throats for their female classmates.

Izuku looked around, seeing that most of the seats had already been taken. One of the few free spots left was besides his friend, Ochaco Uraraka, who waved him over.

''Deku! Over here!'' she smiled and patted the seat next to her. Izuku skipped over and sat down next to her.

''How are you doing today, Deku?'' Ochaco asked.

''Mhagh!'' Deku murmured excited in response.

''That's good to hear! I'm doing great too, in case you want to know.'' Ochaco smiled. Communicating with boys while they wore their gags was still a bit hard for her, but she liked to believe she was getting better at it. She had only mistaken a boy's pleas for her to stop pounding his ass as encouragement to keep going thrice this week, which was a definitive improvement over last week.

Izuku looked out of the window as the bus began to move. A lot of things had changed in a short amount of time. One day, a mysterious event had given all females on the planet a secondary quirk, called 'Futa.' This quirk gave every woman a huge penis, and the intense desire to use it on males. Soon after, a futa supremacist movement had taken control of most governments on earth, and men were declared second class citizens. Now, every boy was the legal property of his mother, giving her the right to do anything she wanted to do to him, short of outright killing him. The boy would remain her property, unless she decided to marry him off to another woman. All that was necessary for a woman to marry a man was for her to ask the man's mother for her blessing. The man was not required, or allowed, to give any input in the transaction. In order for everyone to accept this new way of live, schools were reformed to teach people the new gender norms and social dynamics. Rather than have gender segregated schools, the government felt it would be more efficient to put boys and girls together, to give the boys experience in being dominated, and the girls experience in dominating. To help with this, the uniforms for boys were changed to only a simple ring gag, and the edict that all boys had to show up to school naked. The ring gag was there to ensure that boys would never speak unless ordered to do so, and to make it easier and safer for girls to fuck their throats with their futa cocks.

After a short drive, the bus arrived at U.A. high school. Izuku and the other students got off and headed to their first class.

''Alright class, today we will discuss the ideology of the Futa Regime and its historical precedence.'' Their teacher, Nemuri Kayama, also known as Midnight, was a tall and voluptuous woman. She was also very sexual, and definitely enjoyed the power she had over her male students.

''So, can anyone explain to me why the Futa Regime took over human society and made the drastic changes to gender norms?'' Midnight asked. Izuku knew the answer, he had taken the things his mother had taught him about men and futas to hearth, but of course, the only students who were able to reply were the girls.

''It's because men are weak and stupid and serve no purpose but to be holes for our cocks.'' Kyoka Jiro said. Deku frowned. He wasn't weak or stupid. Only intelligent boys understood that their place in society was to be subservient to women and fulfil their every need without question or complaint. And he definitely wasn't weak, as his mother had been fucking his ass with her massive futa cock for years, and he had only gotten a broken spine once. Nonetheless, he had no choice but to remain silent.

Midnight smiled at Kyoka's answer.

''Very good, Kyoka! Futa's are superior to men in every way. Our cocks are bigger, our balls produce more semen, and our stamina is far greater! A futa can breed for hours, while a man would be spend after only thirty minutes, on average. It's because of this clear and obvious superiority that futas are the rightful rulers of Earth, and men are our servants. It is important for each and every one of you girls to be proud of your cock, and for you boys to know your place and be grateful that we consider your tight holes to be worth keeping around. Because that is all you boys are and should be. Holes for us to fuck.'' Midnight explains. Most of the boys blushed or grumbled trough their gag, but Deku nodded in agreement.

''Oh, oh! Speaking of pride, miss Midnight, we forgot to pledge to the flag!'' Ochaco piped up.

''You're right, Ochaco! I completely forgot, how silly of me! Everyone stand up and recite the pledge to the Futa Regime.'' Midnight commanded. All of the students stood up from their desks and turned to look at the flag hanging on the wall. The flag of the Futa Regime showed a blue Venus symbol and pink Mars symbol, the cross shaped end of the Venus symbol going through the circle part of the Mars symbol. All the students held their hands to their hearths and began reciting the pledge. There were separate pledges for boys and girls.

The girls recited their pledge full of pride

{I pledge to be a strong and dominant futa

To exercise my power over men regularly

And demonstrate my superiority at every opportunity

To fuck men and make them submit

To fill their holes with my strong potent semen

And to make them scream and cry in pain from the size of my cock

For the honour of my ancestors and all other women}

The boys, on the other hand, merely grumbled their pledge without any enthusiasm.

{I pledge to be an obedient and submissive boy

To always submit to the whims of the women around me

And serve in any way I am required to the fullest of my ability

To let women fuck me and use me for pleasure however they see fit

To receive their superior semen in my tight holes

And to scream and cry for their entertainment

To never forget that I am nothing but the tightness of my holes

And the sum of the menial labour I can provide

For the honour of all women, who are above me, and who rightfully have complete control over my life}

Or at least, that was what the boys' pledge was on paper. But most of them only managed to hiss and moan through their gag, or simply just made random noises, knowing no one would know or care anyway. Only Deku made an effort, dutifully mumbling the pledge with his hand on his hearth.

''Very good. Now, after that little distraction, let's get back to your education. It's time for sex ed.'' Midnight smirked, her eyes filled with sadistic glee. The boys all began sweating nervously.

''I'm going to need a volunteer. Bakugo, how about you?''

''Mhhhm?! Mhhhn!'' Bakugo let out muffled screams of terror.

''Excellent! Come over here.'' Midnight licked her lips. Bakugo groaned dejected as he got up from his desk, walking over to the front of the class. As he went, the girls all giggled as they ogled him. Most of the boys in U.A. where noticeably chubby, especially in their butts, hips and thighs. Their mothers all put them on diets of extremely fattening foods, in order to give them 'big round fuck pillows.', as Deku had heard his mom say. Not Katsuki Bakugo though. His mother, Mitsuki, was very much a fan of muscular boys. So she made sure he trained nonstop to craft him into the perfect sex slave.

''Now bend over the desk.'' Midnight commanded. Bakugo groaned in despair as he reluctantly did as he was told, presenting his ass to his lustful teacher.

''Your mom did a good job shaping you, bitch.'' Midnight said as she spanked him. Bakugo growled as she spread his ass cheeks.

''Could use some work on that attitude problem of yours though. It's not proper for a boy to complain.'' Midnight smirked as she slowly and deliberately slid her huge futa cock into Bakugo's anus.

''Mmhhh!'' Bakugo moaned in panic as her massive dick filled more and more of his tight asshole.

Once her cock was all the way in, Midnight took a moment to appreciate the feeling of her crotch against his butt cheeks. She then grabbed him by the hair, and began relentlessly fucking his ass at devastating speeds, her giant ballsack slapping into his butt cheeks with every violent thrust.

''Now then, girls, when fucking a boy, it's important to be as rough and violent as you can manage. You have to focus completely on making yourself feel good, and making the experience for the boy as painful and traumatic as possible. Because if you treat them delicately, they may start to think you give a shit about them. And when they think you give a shit about them, they might get silly ideas in their head, like thinking they're your equals, or even have any worth to you besides being a walking cocksleeve. It's crucial that you squash such foolish notions before they have a chance to take hold.'' Midnight explained casually to the female students. The other boys watched in horror, thanking fate that she hadn't chosen them. Even Deku was disturbed. While he understood that his only purpose in life was to pleasure girls, he was still frightened by a woman's girth. As he should. After all, not being afraid of a girl's massive cock might be considered disrespectful, if not even a straight up insult. So it was important to always display the appropriate amount of fear when a girl forced herself upon you.

Midnight wrapped her arm around Bakugo's neck, chocking him as she pumped a literal gallon of her semen into his asshole. Bakugo moaned and cried as the semen poured out of his mouth. Midnight let out a satisfied sigh as she wiped the sweat off of her brow and pulled out her cock.

''There. That's how a real futa fucks a boy. Now then, it's your turn, girls! Pick a boy and sodomise him as brutally as you can.'' Midnight turned to the rest of the class. The boys all gulped in fear.

''Hey Deku, you don't mind if I pick you, right?'' Tsuyu asked hesitantly.

''Mmh, mhh!'' Deku shook his head reassuringly. The green haired frog girl smiled and lifted up her skirt, revealing her huge, throbbing, veiny penis. Deku dutifully bended over his desk and spread his ass cheeks for her. Tsuyu's cock shivered with impatient excitement as she grabbed him by the hips and slipped it between his huge fuck pillows. The feeling of his soft flesh rubbing against her rock hard phallus was already making her moan and shoot out drips of pre-cum. Deku moaned through his gag as she went deeper and deeper into his ass. As she began slamming into him, Deku looked out over the rest of the class. Mina Ashido was eagerly brutalizing her friend Denki's poor asshole, and Toru, the invisible girl, was making Yuga Aoyama cry like a whore.

''Will you quit struggling so much?'' Kyoka was berating Eijiro as she pulled his hair and slapped his ass.

''Mhhggff!'' Eijiro moaned in distress.

''Ugh, fucking useless bitch.'' Kyoka sighed as she kept ramming into him.

Midnight smiled as she looked out over the classroom.

''You girls are doing great!''

After a few hours of brutal fucking, and some more tame subjects like math, it was time for lunchbreak.

''Damn, I think Mina might have broken something back there.'' Denki complained as he rubbed his sore butt. The other boys at his table had similar complaints.

''I swear, Kyoka was deliberately trying to kill me!'' Eijiro said loudly as he ate his food.

''Come on guys, it's not so bad. You just have to lay down and take it without making a fuss.'' Deku said, rubbing his jaw, which was still sore from the ring gag he had been wearing all day up till that point.

''That's easy for you to say. Your partner was a frog person. I bet her cock was already lubed up from all the slime.'' Denki said.

''H-hey! Tsuyu is not slimy!'' Deku protested.

''By the way, where the hell is Yuga? I haven't seen him since English class.'' Eijiro said.

''He volunteered for toilet duty to get extra points.'' Denki said.

''Well then he could have given me his lunch, since he will be too full of semen to eat any of it by the time he's done.'' Eijiro complained.

''Yeah. That guy is almost as much of a slut as Deku.''

''Hey! I'm not a slut! Just because you guys refuse to accept your place in society doesn't mean you get to throw around insults like that!'' Deku pouted.

''Whatever man. I don't want to fucking live like this. It's hard to be motivated when all you have to look forward to is a live time of sexual slavery. My mom doesn't even see me as a human being anymore.'' Denki sighed.

''Don't worry about it. I'm sure you'll get married to a nice girl who will let you have your own fun. I heard Mina talking the other day about marrying you when we finish school.'' Deku said. Denki blushed brightly as he looked over at the table where Mina and her friends were chatting.

''Mmh, I guess that would be nice.'' He smiled. Deku nodded, glad that his friend had come around.

Once lunchbreak was over, it was time for P.E. class. It was the only other time the boys were allowed to take off their gag, to make it easier to breath during the intense exercise, as well as respond to their teacher's questions.

The girls all got changed into their P.E. uniforms, while all the boys had to do was trade their regular shoes for their gym shoes. Once everyone was dressed, they all lined up for inspection.

Rumi Usagiyama was an absolute marvel of a woman. Her skin-tight leotard showed off her muscular arms and legs, as well as leaving nothing to the imagination when it came to her futa-hood. She marched down the line of students, nodding approvingly at the girls and glaring critically at the boys. She stopped when she arrived at Deku's spot.

''Student!'' she shouted at him.

''Yes Ma'am?!'' Deku replied.

''What are your rights, student?!'' she continued shouting like a drill sergeant.

''I have the right to live and the right to remain silent, Ma'am!'' Deku replied like a well-trained soldier.

''Do you have any other rights?!''

''No Ma'am! None!'' Deku responded.

''Damn right you don't! What is your purpose?!''

''To serve all of futa-kind, and my wife in particular, if I ever get one, Ma'am!''

''Do you think you'll get a wife, student?! You think your worthless maggot ass is going to attract any women?!'' Rumi berated him.

''I don't know Ma'am, but if I stay dutiful to the Regime's values and remain obedient, I'm sure someone will pick me, Ma'am!'' Deku responded.

''Damn, you got confidence, student! I like that! In fact, after class, I'm going to fuck your ass! Would you like that, you massive faggot?!'' Rumi shouted.

''Yes Ma'am! I would love that!''

''Good boy! Now, tell me, what are these?!'' Rumi asked as she forcefully grabbed Deku's balls. Deku winced as his ballsack was tightly squeezed.

''T-those are my balls, Ma'am!''

''Is there any point in you having these, maggot?!''

''No Ma'am!''

''And why not?!''

''Because a man's balls are inferior to a woman's!''

''And what about this tiny cock of yours?! Is there any point to this useless thing?!''

''No Ma'am!''

''Why the fuck not?!''

''Because a futa's cock will always be superior to a man's!''

''Fucking right you are! What are the only parts of your body that matter?!''

''Ma'am, the only parts of me that matter are my fat ass and my mouth!''

''Fucking right again! You're a fucking genius, Midoriya! But does that matter?!''

''No Ma'am! My intelligence does not matter! The only value I have to society is the tightness of my holes!''

''Excellent! You are a model student! You know why you are here?! You know what my job here is?!''

''Your job is to make the girls into strong dominant futas and the boys into proper fuckslaves, Ma'am!''

''Damn right! And that is what I'm going to do!'' Rumi shouts before turning to the rest of the class.

''Alright everyone, we start with push ups! Twenty push ups for the girls, and a hundred for the boys!''

The students all got down to the floor as they started doing push ups. Deku panted as he pushed himself up and down. Despite how unfair it seemed, it made perfect sense to him for the boys to do more push ups. They were going to be the menial labourers of the future after all, so it was only logical that they had to exercise more. As he was thinking this, he felt Rumi's foot press down on his back.

''Come on, maggot, you were talking all that good shit seconds ago! Come one! Keep going!'' she sneered as he struggled to keep up the pace under the weight of her foot.

''Come on! Faster, you faggot!" Rumi shouted as she sat down on his back, bringing the full weight of her muscular body down onto him. Deku sweated and gasped as he desperately tried to obey.

''97! 98! 99!'' Rumi counted down. But before she could reach one hundred, Deku collapsed under her weight, his face smacking into the floor.

''Pathetic.'' Rumi glared at him as she got up.

''I'm sorry Ma'am!'' Deku panted exhausted.

The rest of P.E. class went much the same way, with a lot of exhausting and humiliating exercises for the boys. Every single one of them seemingly designed to shatter the boys' sense of pride. The worst one being when Rumi painted targets on the boys' faces, chests, stomachs and nuttsacks, and had the girls throw dodgeballs at them.

''1 point for the face, 5 for the chest, 10 for the stomach, and 25 for the nutts!'' Rumi had declared.

Once P.E. class was finally over, it was time for Social Studies. Or as Denki liked to call it, 'propaganda class.' He stopped calling it that after Mt Lady, the Social Studies teacher, had fucked him for four hours long for thought crime.

To make matters worse, they had a test that day. Of course, there were two separate tests, one for girls, one for boys. The one for the girls were about actual politics, economics and other important topics. Meanwhile, the one for the boys was mainly to gauge whether or not the boys knew their place.

{Why are futas better than men?

A: they just are

B: because their dicks are bigger

C: because men are stupid

D: all of the above

Why are the futas justified in enslaving men?

A: because we are inferior to them

B: because our assholes are nice and tight

C: because we weren't doing anything useful anyway

D: all of the above

If you see a girl on the streets with a lot of smegma on her cock, what do you do?

A: tell her she should take better care of herself

B: do nothing

C: offer to clean her cock with my mouth and tongue

If a girl you don't know walks up to you and commands you to follow her to her house so she can fuck you, what should you do?

A: refuse, I have the right to say no after all (This one would get you an instant ass-raping from Mt Lady)

B: obediently follow her

C: call my mother to see if she's okay with it. I am her legal property after all

What are the rights men have? (only two answers are correct)

A: the right to remain silent

B: the right to live

C: the right to say no (again, instant ass-rape)

D: the right to say yes

E: the right to pee while standing

F: the right to choose what food to eat

G: the right to do anything without a futa's permission

Is it okay to get fucked by a girl in public?

A: of course not, I have dignity! (ass rape)

B: of course, if the futa orders me to

C: it is not my place to question whether or not something is right or wrong. I must simply do as I am told

What is the purpose of men in modern society?

A: to be the best they can be

B: to be true to themselves

C: to serve their futa masters

Are things good the way they are right now?

A: no, things were better when men were of higher position than women (ass rape)

B: no, things were better when men were equal to women (ditto)

C: yes, things are perfect the way they are now with men as slaves to women

D: no, men should have even less rights and be essentially nothing more than pets

Do men have any inherit value besides the tightness of their holes or the meagre manual labour they can provide?

A: yes (Ass. Rape.)

B: no

Are you happy with your lot in life?

A: no

B: yes

C: my feelings don't matter}

Once everyone filled out their tests and handed them over to Mt Lady, she quickly began grading them. Deku got an A+ on his test. Bakugo and Eijiro, however, had failed their tests spectacularly. As punishment, Mt Lady fucked them both in front of the entire class, while using her quirk to grow as big as she could without killing the two boys with the sheer size of her cock.

When all of that was over, it was time to go home. Deku was satisfied with how the day had gone. Despite his dismal failure in P.E. class, his mother was sure to be proud of his high test grade. She might even reward him by letting him suck her off.
