Izuku chuckled softly and sweated somewhat nervously. He was in the middle of a training exercise and felt that his partners were taking things a tad too seriously. Perhaps it was due to the fact they had to take the active role in the exercise while he simply had to remain tied up in a chair.

Ochako and Momo glared at each other fiercely from across the training stage, one of the buildings designed to look abandoned-looking near UA High. It was just like their earlier training routines, a simple game of heroes vs villains. Ochako was the hero and Momo was the villain.

It had been a week since these two girls, along with Mina and Jiro, had taken special pills that essentially made them very, VERY obese. Since then everyone had adjusted to their new heavyset classmates while Izuku simply tried to keep up with the four. It wasn't easy in the slightest but it was worth it.

Ochako smirked, the heroine changing from her normal, happy-go-lucky self into the serious hyper-combat oriented commando mode she picked up from shadowing Gunhead. She confidently held a ready pose, eager to leap at her target. Despite her appearance, Ochako and Momo alike were entirely unhindered by their size and weight. Both were just as powerful as when they were skinny, maybe even more.

Momo faltered for a mere second as she gazed into Ochako's eyes. It was like staring at an adorably flabby yet ferocious blob. She blushed as she took in how tightly Ochako's updated outfit hugged her. So many fat folds and rolls being snugly wrapped up in the stretchy fabric. Plump breasts, a low hanging belly, such wide hips, and an ass as bubbly and round as Ochako's personality! Momo was sweating bullets and the fight hadn't even started!

"Gotcha!" Ochako exclaimed as she saw Momo falter. She used her quirk on herself and jumped up towards the ceiling. Her soft body made contact with it around her lower back, just above her butt. Ochako had quickly positioned her legs while in flight and pushed off of the ceiling. This sent her towards Momo like a wrecking ball. Though in this fast-paced assault and the moments that preceded it, Ochako had been similarly observing Momo as the creation hero had done to her. While her outfit covered everything below her neck, Momo's left plenty of openings to allow her to use her quirk. Her thighs and arms were out sagging and jiggling freely, four tubes of blubber that Ochako needed to take seriously. It was hard to do this though when Momo's shirt hardly covered a quarter of her immense rear on top of how her belly and cleavage almost entirely hung out of her top. It took the dedication of a saint not to blush.

"W-wait we're starting now?!" Momo shrieked in surprise before Ochako slammed into her. Their bellies collided with an audible slap as the force of Ochako's movement transferred into Momo. "Gah!" She groaned and fell onto her back, her entire body wobbling about as she lay dazed.

The impact sent Ochako flipping backwards in the air before she released her quirk. Like a cat she landed on her feet, her belly falling down to bounce off of her knees. "I'm gonna get Deku, win this exercise, and then I GET TO GO ON A DATE WITH HIM!" Ochako exclaimed and jumped above Momo, intending to slam down atop the other fatty. This was her purpose for being extra ferocious. Whoever won here would get to take Izuku out for a date ON THEIR OWN! No third, fourth, or fifth wheels like all the other times.

Momo's eyes widened as Ochako's shadow fell over her. The declaration of what their match had at stake spurred her into action though. She rolled out of the way, her belly squishing against the ground momentarily. "You think I'll give up so easily?!" Momo asked as she clambered to her feet. She hesitated for a moment before placing her hand over her belly. With the aid of her quirk and a minute amount of fat, Momo pulled a foam sword from her belly rolls. Even if Ochako had enough fat to take a solid hit, Momo didn't want to strike her friend with something too hard.

The strike was easily deflected as Ochako grabbed Momo by her thick wrists. The two paused as Ochako smiled innocently. Momo smiled as well but with a notable shade of nervousness, accented with an awkward chuckle. Within the next few seconds Ochako twisted Momo's wrist, taking extra care to not hurt Momo, but still managed to push her to the floor. Momo's cheek was squished against the concrete floor as she rested atop her cleavage and midriff. Ochako seated herself atop Momo's plentiful rolls of back fat, her titanic rear squishing against the soft lumps of pudge. "And I think it's obvious that I've won. Now just stay still and I'll…" Ochako froze as she reached for her belt. There was supposed to be a pair of handcuffs there. A pair that Ochako had been given before the training exercise began. One possible way to win was to cuff the villain… "And I'll…save the captive. You wait here, villain!"

As Ochako let up the pressure on Momo, she pushed off of the ground. Momo used her quirk to produce two poles from her belly. The two pieces of metal pushed Momo to her feet which in turn sent Ochako rolling backwards. This was all the time Momo needed to grab her boyfriend Izuku who had been watching the entire spectacle. "Just hold still a little longer darling. When I win I'll take us to a lovely restaurant." Momo lifted the chair with her captive and charged toward Ochako who had just gotten to her feet.

"Jeez…my butt is huge but that still kind of hurt Momo…hey wait what the?!" Ochako cried out in shock as Momo rammed into her with Izuku in hand. Ochako was back on the ground but now had Momo on top with Izuku sandwiched between their breasts. Before she could recover, Momo leaned in and kissed Ochako deeply. This surprised her but as the tender feeling of Momo's lips pulled her in, Ochako slowly gave in and kissed back.

Izuku had been freed from his chair but was now caught between two heavy yet soft girls. Most of his body was sandwiched between two warm and marshmallow-soft bellies while his head was christened with four immense boobs. A smile was plastered on his face and a small drop of blood leaked from his nose.

Win or lose, he was beyond happy…
