Chapter 6: Training for the Sports Festival

Jirou was at her wit's end. Every since she eavesdropped and masturbated to Eijiro, Mina, and Itsuka fucking, the purple-haired girl had been feeling awkward and guilty whenever she looked at her classmates.

Sure, it would have been one thing if she rubbed one out to some random porn star or pro-hero, but she had eavesdropped on her friends. Jirou felt like she had broken some kind of taboo.

'But what the hell am I supposed to say? "Hey, guys. A few weeks ago, I heard you fucking your girlfriend and masturbated to sounds of you banging each other. Whoops, my bad?!"'. Jirou thought with a sigh as classes ended for the day. The vast majority of Class 2-A had already packed up their stuff and headed out. A few of those stragglers happened to include Ashido and Kirishima, the redhead rubbing his girlfriend's hair to make her feel better about the quiz they just took. 'Fuck it. It's now or never.'

Jirou approached the two. "Hey, guys. I need to tell-"

"Excuse me." Yaoyorozu suddenly interrupted.

"Ribbit." Asui chimed in. The five then noticed the awkward air caused by the sudden interruption.

"Sorry, Jirou." The black-haired girl said.

"No, go ahead." The punk girl replied. 'Oh, thank god!'

"What is it, Yaomomo?" Mina asked the creation girl.

"I need to ask a favor of you and Kirishima. You guys know how the Sports Festival is coming up soon?" Yaoyorozu asked, getting a nod from the couple. "Well, I want to do better than last year."

"Hey, you did your best. At least your match didn't turn into a draw." Eijiro said, referencing when he and Tetsutetsu decided their match with an arm-wrestling competition.

"Still, I need to show I've improved since then. I'm faster at creating less-complex but useful creations, but I believe my combat skills and physique are...lacking." The black-haired girl said with a slight frown that quickly turned into a determined look. "You two and Kendo are probably the fittest among our two classes. So I was wondering if you would help me get into fighting shape, And perhaps Kendo would help me with my hand-to-hand combat."

Mina looked at the creation girl with a hint of suspicion...that lasted all of ten seconds. "Sure thing, Yaomomo!"

"Hell yeah! Just give us a few weeks, and you'll be good to go." Eijiro said with a toothy smile, to which Yaoyorozu responded with her own.

"Thank you." The black-haired girl said with a polite bow.

"Huh. I was actually gonna ask the same thing, ribbit." Asui said with a finger on her chin. "I figured if I strengthen my leg muscles, I'll be able to leap higher."

"No problem. The more the merrier." Eijiro said before turning to Jirou. "Did you wanna say something, Jirou."

The purplette got an embarrassed look on her face before tapping her jacks together. "I...I was hoping to get in shape for the Sports Festival too. I-I mean, I don't want to get super buff or anything, just...you know, fit enough to handle the races and stuff."

"Hey, the more the merrier." Mina said. "Eiji, Itsuka, and I are gonna have a workout session tonight. You guys wanna join us?"

"Of course." Yaoyorozu answered.

"Sure." Asui replied.

"...okay." Jirou answered.

"Alright. Just be sure you guys were comfy clothing." Eijiro said as he and Mina headed out. "Oh, and bring some water. Last thing you want to do is get dehydrated during a workout."

"I'll text Itsuka and let her know what's up." Mina chimed in. "See ya tonight, girls!"

The muscular couple left the room, leaving the girls to themselves as they packed up their things.

'Dammit!' Jirou thought to herself. 'Now what am I going to do?!' The punk girl couldn't exactly say her apology with the other girls around. Oh well, she could at least get into good shape. And maybe actually hanging out with Ashido and Kirishima would make her feel less guilty.

Unbeknownst to Jirou, Yaoyorozu and Asui's intentions weren't exactly pure. Yes, they did want to get into better shape. But they also had other motives.

Ever since she accidentally barged in on them, Yaoyorozu often thought of Eijiro and Mina's buff bodies. The rich girl had spent nights tempted to...relieve herself to thoughts of her classmates, but composed herself before that could happen. But she still felt a desire to see them. Now, she could tell that what they and Kendo had was beautiful, but she had no intention of butting into their romance. Still, there was nothing wrong with looking, right?

By contrast, Asui was a girl with a mission. These last few weeks, Kirishima had unknowingly wormed his way into the amphibian girl's heart. And based on his current girlfriends, Asui knew that the only way she would have even a chance to get with the redhead was to bulk up herself. And if Ashido was comfortable sharing Kirishima with Kendo, surely she wouldn't mind one more girl in their relationship, right?

That night…

'Well, this is awkward.' Asui thought to herself. Like they agreed on, she, Yaoyorozu and Jirou meet the muscular threesome at the UA Heights Gym. What they weren't expecting was to see Tsunotori, Yanagi, and Tokage had also decided to join them in working out, having talked to Kendo earlier. Like with the 2-A girls, the 2-B girls claimed they wanted to get in shape for the Sports Festival.

But what were their other motivations?

Tsunotori's was simple; she wanted to be surrounded by sexy, muscly people. Indeed, the innocent-looking girl was secretly a huge pervert. And by becoming regular workout buddies with Kendo, she would get a free show of the Class Prez and her boyfriend & girlfriend pushing their awesome bodies to the limit. Her getting in better shape was just a plus.

Tokage's motive was one part horniness and one part revenge. Her plan was to become a savant at pumping iron, hoping to become even bigger than Kendo! She would no longer need to be worried about being on the receiving end of the infamous Kendo-chop whenever she did something stupid. And maybe she could have the threesome worship her as their buff mistress, or something like that. The reptile-loving girl was improvising as she went along.

Yanagi only joined in because she didn't want to feel left out. But if something naughty happened...she wouldn't be opposed to it.

All six of the girls were dressed in appropriate workout gear. Jirou, Yanagi, Tsunotori and Asui were wearing t-shirts, Yaoyorozu wore a sleeveless shirt, and Tokage wore a dark green sports bra. A few of the girls wore sweat shorts (Jirou, Tsunotori, Asui and Tokage) and sweatpants (Yaoyorozu & Yanagi).

"Alright, you guys are dressed for the occasion." The six girls turned and saw Eijiro, Itsuka and Mina dressed in their usual workout clothes, the sight of which caused several varying reactions from the girls, since between the trio, they put on a combined total of over 40 pounds of muscle over the summer. Itsuka then brought her hands together. "I hope you're ready to sweat."

'Well, no turning back.' Jirou thought to herself. 'Eh, it's just weights. How bad can it be?'

43 minutes later…

"Uuuugggghhh! Someone kill me!" Jirou groaned, laying her back after having done a full set of arm curls, her arms now feeling like wet noodles.

"Come on, it's not that bad, ribbit." Asui stated as she wiped the sweat from her brow.

"Wow, you're really out of shape, ain't ya, Lobes?" Tokage said with a smirk.

"Don't be mean, Tokage." Tsunotori said as she stretched inbetween her exercises. Jirou was using the ab crunch machine, taking a break to take a drink of water.

What were Yaoyorozu and Yanagi doing? They were watching the muscular trio working out. Itsuka was using the leg press machine, Mina was doing bicep curls with 90-pound weights, and Kirishima was bench-pressing 200 pounds. For the other girls, watching the three so focused on exercising was strangely hypnotic.

"Hubba, hubba. Am I right?" Tokage whispered to the other girls, snapping Yaoyorozu and Yanagi out of their staring.

"Oh, I should get started, right?" Yaoyorozu said with an embarrassed look while Yanagi silently began to run on the treadmill.

For the next hour, Eijiro, Mina and Itsuka gave advice to the six single girls. This also meant getting up close with them, much to the embarrassment (and slight arousal) of a few of the girls. Mina spotted Tsunotori as the blonde bench-pressed 70 pound weights, her innocent poker face in full effect as she tried not to look at the pink girl's sports bra-clad bosom.

Yanagi was completely stiff when Eijiro gave her some pointers on using the pulling machine, the poltergeist girl shivering as she felt his hands get her into the right position.

And when Itsuka held Asui's arms to show her the best stretching position, the greenette held in a nervous croak as she felt the orange-haired girl's large arm rubbing against her own.

After another hour of working out, the six girls were tired from the workout while the trio did a post-workout measurement.

"Hot damn, Itsuka! 22 inches!" Eijiro said with astonishment.

"Nice." The orange-haired girl said with pride as the redhead went to examine Mina's biceps.

"Twenty inches."

"Alright!" Mina said with joy before she decided to measure Eijiro's biceps. "Looks like you're twenty inches too."

"Huh, so Itsuka's more buff than either of us." The redhead said.

"Jealous?" The teal-eyed girl asked.

"Naw, that just means I got to push on even more." Eijiro said, Mina nodding in agreement with her boyfriend. With a smile on her face, Itsuka leaned over and gave each of her lovers a kiss on the cheek.

"Christ, get a room, guys." Tokage said, making the threesome remember that there were other people in the gym with them. Tsunotori and Yaoyorozu giggled at the sweet side, while Yanagi and Asui looked on with neutral looks and Jirou looked away with a light blush on her face.

"That's gonna take some getting used to." Eijiro stated while rubbing the back of his head.

And so, Eijiro, Mina and Itsuka's regular schedule was interrupted by six new workout companions. Suffice to say, the weeks leading up to the Sports Festival were going to be really interesting.

Author's Note: A shorter chapter meant to set up how the rest of the harem gets involved with our muscular threesome.

I have to be honest with you guys, I've made some changes to the story. Both due to me realizing that a harem of 12 girls would be both excessive and difficult to write. So I shortened it down to eight girls.

Superheavy: Itsuka Kendo, Mina Ashido

Heavy: Reiko Yanagi, Tsuyu Asui, Setsuna Tokage, Momo Yaoyorozu

Light: Kyouka Jirou, Pony Tsunotori

I was also kind of disappointed with the Heavy Build poll, and gave Nejire's votes to Reiko, because a silver-haired Kuudere with a Heavy Muscular Build sounds hot as hell.

Sorry, but sometimes you have to go with your instinct. But I'll still have other polls for later down the line.

Have a safe day, folks!
