The Effects of Gravity [My Hero Academia BBW/WG]

“Izuku! Sweetie! Wake up! You’re going to be late!”

The green-haired boy’s eyes immediately shot open. “C-Crap, I overslept!” Having just spent the last month away from school on summer vacation, his sleep schedule had fallen greatly off course. He quickly leapt out of bed and dug into his closet, pulling out the standard U.A. school uniform. Now clad in a grey jacket and black slacks, he rushed down the stairs to find his mother, Inko, already waiting for him with breakfast in hand.

“Here’s your breakfa- “ Before she could even finish, he had grabbed the plate and downed all the food in an instant. Despite nearly choking on it, he managed to force it down, gasping for air afterwards.

“Thanks Mom! I gotta run!” With that, he sped out the door, leaving her in the dust.

“Have a good day!”

Normally, running late like this would pose a problem. However, with his superpower, or Quirk, he was granted super strength which allowed him to leap and bound his way to school. A green, almost electric-looking energy surrounded his body as he bounced from building to building, leaving the traffic below in the dust. Before long, he had already arrived at the school grounds, and with a few short moments to spare.

“*Phew*, just made it.” Izuku let out a sign of relief. “Feels good to be back at U.A.”

U.A. High School was one of the most prestigious academies for up-and-coming heroes in the country. Thanks to the rigorous screening and testing process, only the top percentage could manage to attend it. It had been his dream to attend, and here he was, already well into his school life there.

“Hey! Deku!” A familiar voice rang out. Hearing his nickname, Izuku looked up. A taller boy with blue hair and glasses was standing near the front entrance of the building. It was Iida, one of his close friends and fellow classmates. It came as no surprise that he had been early, both due to his role as class president and his Quirk giving him incredible speed. If anything, he’d be the one to crack down on any tardiness.

“Ah, Iida! Good to see you again.” He quickly joined him at the top of the stairs. “Is it just me, or did the break pass by too quickly?”

“Eh, I guess I was kind of ready to get back to class, you know?”

“I mean, I guess…” Deku paused for a moment. “Hey, have you seen Uraraka come by yet?”

“No, actually.” He seemed lost in his thoughts for a second, adjusting his glasses. “Now that I think about it, I can’t recall a time she ever showed up this late for class…”

As if on cue, the two boys could hear footsteps plodding their way. They seemed louder than most, thundering towards the campus. There was an urgency to them, but at the same time it was much slower than a normal running pace. When they turned their attention toward the source of the noise, they couldn’t believe their eyes.

Ochako Uraraka had finally arrived on campus, but there was something drastically different about her. While it wasn’t too unusual for some people to return from their summer vacation looking a bit tanner or with a new haircut, her fair complexion and chestnut-colored bob cut were just as they had been before the break. The rest of her, however, had undergone a big change. It was almost as if she had been replaced with a comically fat version of herself. Her once slender frame was now buried beneath hundreds of pounds of flab, wobbling with every step she took. Despite her running gait, her actual speed was relatively slow as she made her approach towards the staircase sitting before her. With a bit of effort, she managed to climb the stairs to the boys’ side.

“*haaaah* Good morning…Deku…Iida…” She managed to squeak out between labored breaths. Her doughy chest rose with each deep gulp of air she took. Those puffy cheeks of hers had grown bright red in addition to their natural blush, almost resembling a ripe pair of tomatoes.

“U-Uraraka!” Deku’s own face grew red. There was something embarrassing about seeing her at this size, especially when she had been so much thinner the last time they had met.

“Y-Your uniform…” Iida too had grown flustered.

While the rest of the students had their proper school uniforms on, Ochako was sporting something significantly more stretchy. While her pants were from U.A., they were meant to be part of her gym attire. The blue, white-striped material managed to coat her meaty thighs tightly like a second skin with just enough room to partially tuck her belly in. She was also sporting an ill-fitting black tank top which left a large amount of cleavage, stomach, and armfat on display.

“I can’t help it. They didn’t send a new uniforms in time and this is all I can fit into right now…”

“Wh-What happened exactly, Uraraka?” The green-haired boy was concerned by his friend’s sudden transformation.

“Well, my doctor thinks it might be some kind of secondary manifestation of my Quirk…”

“Hm, what would gaining all that weight have to do with anti-gravity?” Deku wondered.

The group could hear the school bell going off inside the building. “Quick, we have to get to class!” Iida said, opening the door for his friends. Letting Ochako go in first, however, may not have been the best idea as she quickly found herself wedged in the doorway.

“Th-This is embarrassing…”

“Here, we can get you out!” With the combined power of their Quirks, the two boys were able to push their fattened friend through the doorway. The three sort of just collapsed in a big pile, the brunette acting as a makeshift cushion.

“Ow…”
____________________

Class 1-A was abuzz with the sounds of students all discussing their summer vacations with one another. While most had ventured out from their desks, Ochako had quickly taken to her seat to rest from lugging her massiveness around. Her desk in the back corner of the room kept her out of sight to a degree, though eyes had originally all shot towards her the moment she had struggled to enter the classroom. Deku and Iida had stayed by her side, helping move her desk and chair so she could even fit without her gut being painfully compressed.

A short boy with bulbous, purple hair suddenly weaseled his way over to the fat girl’s desk. Without warning, he dug his face right into her belly.

“Aaaah, Uraraka, I didn’t know you were going BBW~” Mineta said, muffled by the flab. “I love how soft you’ve gotte- “

A large, pink tongue flew out towards the boy, knocking him away from her body. He was launched into the air, sending him crashing back over to his desk on the other side of the room. It belonged to Tsuyu, their frog-like friend. She had little tolerance for his shenanigans, so the moment her big, wide eyes saw him approach, she readied her tongue and thwacked him square in the side of the head.

“Ah, thanks Tsu~” The brunette smiled.

“It was nothing, kero.”

“Alright class, take your seats.” A man with long, black hair and a large beige scarf walked in the doorway. Their homeroom teacher, Mr. Aizawa, looked as tired as ever. He quickly plopped himself down at his desk at the front of the classroom.

Class was now in session, and the rowdy students found themselves struggling to concentrate much at all. Summer had really done a number on their attention spans, so the first day back was never going to go well. Despite this, Aizawa managed to keep them relatively well behaved, though there was one incident he couldn’t have predicted.

Ochako could hardly concentrate on the lesson at hand. She quickly found her mind floating away, completely detached from her surroundings.

“Man, I’m already so hungry. When was lunch again?”

A low gurgling began to erupt from her stomach. Being in the back of the room, she was lucky her gut’s groans weren’t attracting attention from the others. She gave her flabby middle a quick rub with her sausage-like fingers. Even the small, round pads on her fingertips had swollen up thanks to her gain. These were the pads that gave her access to her Quirk, and her belly rub seemed to inadvertently activate her Quirk’s new secondary power.

The brunette’s desk began to slide toward her huge gut, sandwiching her between it and the chair. The shriek it made as the legs slid and scraped along the classroom floor was enough to attract attention from those sitting nearby, including Iida.

He turned around and whispered, “Is everything alright?”

“*Ngh*, y-yeah, no need to worry...”

Suddenly, Iida felt his chair slide and crash into Ochako’s desk. His own desk quickly joined in, tightly locking him in place.

“I-Is this your Quirk acting up?”

Her gravitational pull grew stronger as her grapefruit-sized cheeks reddened once again. In one huge wave, the students and their desks were getting pulled into the pileup, forming a large half-circle in the back corner of the room. A cacophony of clanging rang out as twenty desks, chairs, and students collided. The force of their impact was enough to send a shockwave throughout the school, rattling the building’s numerous glass windows.

Within seconds, Mr. Aizawa turned around and away from the blackboard towards his now stunned homeroom class. A bright red flash emanated from his eyes. His own Quirk was one that could neutralize the powers of others. With Ochako’s gravitational field now turned off, the squeezing force that had gripped the student body had left, allowing them all to breathe again. Slowly, they began to move all the desks back into place, restoring order to the classroom.


With no need for her to move around the room, the massive girl sunk down into her seat. She felt like there must’ve been eyes all around the room staring daggers at her bloated body. “I’m so embarrassed...I need to disappear for a bit.” She raised a big, meaty arm into the air. Even the slightest motion seemed to send her chub into a wobbling frenzy. “M-May I be excused?”

Aizawa sighed. “Alright...”

The brunette managed to free her doughy form from the clutches of her desk and stood up. She tried her best to shuffle sideways through the aisle of desks, unintentionally knocking things off other people’s desks with her ass and belly. By the time she had reached the front of the room, she was already huffing and puffing from merely walking a short distance. Deku was amazed she had even made it to school like this. She could just barely squeeze out through the doorframe as she left the room.

Concerned for his friend, Deku decided to raise his own hand as well. “May I be excused too?”

“Sure, she seems like she could use some help.” He smiled, sharing a knowing glance. The green-haired boy quickly hopped from his seat and ran out the door.

Immediately, Ochako’s body filled his field of view. Completely out of breath and sweating, she had barely made it 5 feet before slumping up against the wall in a big, sweaty pile. Their eyes met as he approached her.

“Oh...*huff*...hey Deku...” She raised a chubby palm and waved. Her arm fat rolled like a wave as she swayed her hand back and forth.

“Uraraka, are you ok? What happened back there?”

“W-Well, it’s just...I’m having a rough time...” She sighed. “Back around when summer vacation started, I suddenly began to balloon up. My doctor seemed convinced it was due to my Quirk, and it seems like he was right. My body kind of has a passive gravitational pull now, but it gets worse when I touch my gut.”

“I see.” He replied. “You got hungry and grabbed at it, didn’t you?”

“That’s the thing. With this new body, my hunger has been off the charts. A decent amount of this weight I put on has been from all that I’ve been eating. It might’ve seemed like I had everything under control, but I don’t. I-I didn’t want to let everyone down by seeming weak. I don’t know what I’m going to do...” A tear rolled down her pudgy face, mixing with sweat as it traveled.

“Well, I’ll try to help in any way I can!”

“*sniff* R-Really?”

“Of course.” He smiled. “I can help you with weight training. You might lose a few pounds, or at the very least carry them easier...”

“Oh, thank you!” She cried out. A familiar sensation overtook Deku’s body as he found himself pulled closer to her, quickly being enveloped by her flabby form. Both of their faces grew red as they realized just how close their bodies were now. They exchanged nervous chuckles and looked away.

“I guess our Quirks are active again...” She giggled.

“Y-Yeah...”

“C-Can you help me back in? I’m a bit tired...*hooh*...”

Looking around, Deku saw a rather large, bulky textbook lying in the hall. He walked over and grabbed it, bringing it back to Ochako.

“Maybe this could help? Use your Quirk on it real quick.”

She tapped one of her padded fingers onto the book, making it float. He grabbed it and placed the book beneath her stomach, propping up all the blubber as it rose upward. She took a few cautious steps, getting used to it being stuffed under there.

“Wow, this actually kind of helps. Thanks Deku, you’re so resourceful~”

“Hehe, no problem.”

He managed to wrap one of her pillowy arms around his shoulder, acting almost like a crutch for the big girl. With Deku by her side to steady her, she managed to safely waddle down the hall and back to the classroom. It was the beginning of a new chapter in their friendship.
