Sweaty - for good and ill

"Fuck, my legs are stretching apart, Izuku!"

"Come on, Jiro. You can do it."

"It's...ugh! It's too big!"

"This was how I started. You've got this!"

Kyoka groaned and pushed the tire more. Her feet dug into the sand, the coarse grains fighting back with every heave of her little arms. Izuku had said he would start her out the way he had, with pushing objects she wasn't strong enough to lift. He hadn't told her that made things harder. The sand offered resistance for the massive truck tire she was pushing. Not only that, but it prevented her feet from getting a good grip too, making an already tough job ten times harder.

The tire got stuck in the sand. She kept heaving and found the only way she could go was up. So she did. Kyoka grunted and huffed until she managed to flip the tire over. She panted and stared at the green-haired boy, who gave a well-meaning but unhelpful thumbs up. He was lucky that smile was cute.

"Were you as scrawny as me when you started?" she asked.

"I-I wouldn't say you're scrawny. More...petite?" Izuku blushed and rubbed the back of his head. "But yeah, I didn't have a lot of muscle at the beginning of this. But I'm getting more, right? You will too."

Kyoka sighed and wiped her brow. "You're lucky that positive attitude is infectious. Alright. Let's get this damn tire to the dumpster."

The workout had been...well, work. A lot more than Kyoka had expected. Izuku and Izumi had gotten there well before her. When she'd arrived, Izuku had been kind enough to move a lot of the trash around to make it an easier workout for her. She hadn't expected that. He was really giving it his all to help her train. Here she was, impeding on his own training, and he was putting his all into helping her. She tugged one of her earjacks subconsciously and looked away.

"Say, um...w-where's Izumi wandered off to?" she asked.

"She brought her tools today, so she probably found a flat spot to work," Izuku said. "Do you wanna take a break and talk to her instead?"

"No. No, I'm not gonna be a quitter. Let's keep going." Kyoka **** out a grin, even with her arms and legs shaking.

As Kyoka continued getting put through the ringer, a hypnotic bounce of soft, braless breasts proceeded Momo's arrival. She'd opted to be dropped off a few blocks away so she could jog to the beach. It was quite fun doing so without a bra, getting some appreciative stares from boys and girls alike. They could look, but never touch. Not unless her Mistress ordered it.

Momo was the first to find Izumi. She'd spread out a bunch of parts across a table she'd propped up with various cans and stuff. She had an extending rod with some electronics in the handle, some kind of launcher on a rotating piece, and another shooter. She kept going from one thing to another, testing, tweaking, and clapping them together as she was trying to think of a way to put them all together.

"Hey, Izumi," Momo smiled and sat down beside her. The girl did a little nod, bouncing just as much as the genie. Seemed she wasn't the only one not wearing a bra today. "What're you working on?"

"Oh, this is what I'm doing for my application into UA," she said. She held up the rod. "This is a battle baton with an electrical stunning feature. It'll also have a USB for data collection for espionage." She held up the rotating launcher. "This is a bolo launcher. It fires three balls with a tensile string connecting them in a way that'll trip people. Alternatively, it can also be fitted with spike bits to pin someone to the wall." She held up the chamber that looked more like a typical gun. "And this will fire various different projectiles. Rubber shots, expanding capture foam, and a chemical fire suppressant was what I was thinking."

"Very interesting..." She picked a piece up and looked it over, then set it back down. "If I'm counting that right, that's 8 different functions in a single tool. I'd love the blueprints to be able to create something like that in the field." She put her hand to her chest and pulled out some fresh wire for her.

Izumi's eyes sparkled. "Your quirk is treasure boobs?!"

Momo covered her mouth and chuckled. "Something like that. I can create inorganic objects through the lipids in my body. It's also what keeps my figure...well, like this," she gestured to herself, well aware of the blessings her quirk had granted her body. Also, her being a genie meant that that figure would now stay perfect, but she didn't have to share that.

"That's so cool. I wish I had a quirk like that. It'd make it so I could work on any of my inventions without having to scrounge for parts." The greenette looked down at her chest. "Instead, all my food seems to go to these." She shimmied side to side.

Don't grant the wish. She's not your Mistress, Momo thought to herself. "No loss there," Momo said. She moved her own chest and made hers bounce too. "Sometimes I wish my quirk was less efficient, so they'd get even bigger. Kyoka seems to like them big."

"K-Kyoka?" Izumi blushed. She likes them big? Would she like mine? "W-Why do you care if she likes them big? Do you like her?"

Momo shifted herself closer to the girl and whispered. "Come on. you can't tell me you don't think she's something special. She's a cool, aloof rocker girl. And she wants to be a hero, which in itself is something to admire. And just picture what she'll look like after all this training. That petite body will be packed with tight muscles. She's small enough that she'd be like a second Mirko. Wouldn't you want that looking at you?"

Izumi's cheeks turned red. She wiped beads of sweat off her brow as the idea of Kyoka flashing her abs at her and flexing some muscley thighs entered her head. "A-Are we, um...a-are we rivals for her affection if I do want that?" she asked, her voice barely breaking a whisper.

Momo leaned herself against Izumi and wrapped her arms around in a hug. Her hands hovered just shy of touching Izumi's chest. "Who says she has to choose?" she crooned softly in her ear. "Don't you think a girl like Kyoka deserves to have as many beautiful, busty girls as she wants at her beck and call? Isn't it kind of hot picturing you and another girl pressed against her, both of you praising her tight little body at the same time? Don't you want her to touch? To kiss? To rub those jacks against your...?"

She stopped when she saw Izumi squirming in her seat. With her freckles, her face looked like a strawberry. Her arms pressed her chest together, hands curling under her skirt. Momo grinned and leaned back. Now she's thinking about being the first in Mistress's harem. Our lovely girl has been primed. And I doubt she'll be able to resist. She stood and patted Izumi's head.

"I'll leave you to think about that." Momo sauntered her way over to Kyoka and Izuku. Izuku was trying to talk Kyoka into continuing, and then seemed to panic and run to get water. The reason why was because Kyoka was completely frozen still, her face as red as Izumi's. Ah that's right. Her super hearing. I bet Mistress heard all of that.

"I wanted to get to know her, not invite her into becoming a boob-****," she hissed through her teeth when Momo approached.

"Are you going to punish me, Mistress?" Momo asked with a small grin. "Besides, it would be fun to get to know a boob-****."

"I - ugh!" Kyoka rubbed her eyes. "I am going to try and stop her from bluescreening." She looked over as Izuku came back with water. "Thanks, Izuku." She took a long drink and even dumped a little on her forehead to cool her down. Then she grinned over at Momo. "I'm gonna take a short break. Wanna start putting Momo through her paces now?"

"Um, sure. If that's okay," Izuku smiled up at Momo.

Oh. Right. Mistress knows how to punish. Momo took a deep breath in preparation for whatever workout she'd be subjected to.

Kyoka walked up to Izumi, admiring the back view of her. That curly green hair made a nice, thick mane behind her. She was fully covered, but her hips were wide, and her imagination ran wild thinking about her getting up and bending over. She wasn't used to thinking perverted thoughts, but she blamed Momo for putting her brain in that lane! It didn't help that the idea of a bunch of big-boobed girls fawning over her while she played with their knockers was really appealing!

Stop! Stop, Kyoka! Fuck, you must be so red you're probably glowing! She cleared her throat, making the greenette jump. "Hey."

"Oh, um...hi." Izumi waved sheepishly. Her eyes traveled to the hem of Kyoka's shirt. Her belly button poked out. She shrunk a bit more as ABS flashed in her mind. "H-How's training going?"

"Exhausting," Kyoka sighed. She walked over and sat beside her. "But I guess it will be worth it at the end. I hope I get some muscle at least. I don't wanna be a beefy girl, but I'd at least settle for not having noodle arms."

"Just noodle ears, right?" Izumi asked with a small chuckle. Kyoka looked over at her and covered the jacks at the end in a hand. The girl's face immediately fell and she shook her head. "Wait! No! That's not what I meant! I think they're really cool and sexy! I swear! I was just trying to make a joke and I didn't mean to insult you or anything I - ugh!" She covered her head and bent over.

"...Pfft!" Kyoka covered her mouth as long as she could, but eventually she let it out. "Hahaha!"

"You're...you're not mad?"

"I was at first, but I can't help it. Watching someone make a fool of themselves by accident is funny to me. Especially if they're not normally fools. And you're some kind of tech genius, right?" Kyoka wiped her eye. "That's why it's funny."

"I wouldn't know about genius..." Still, though, she smiled. "I mean it, though. Those jacks are really cool."

"And sexy?"

The girls blushed and looked away from each other. While hiding her shame, Izumi noticed Izuku now working out alongside Momo. She remembered yesterday..."Y-You know, I didn't know you were into girls. I thought you liked Izuku from yesterday. Or did Momo just assume you like girls?"

Kyoka thought about it. Her brow scrunched up and she sighed. "Haaah...I don't know. I guess I like both? I used to think the reason I focused on other girls' chests was envy - and maybe it still is - but...I like looking at them. Big. Bouncy. So, so soft..."

Izumi blinked. Did she touch boobs recently? Momo's?

"But, I'm pretty sure I like guys too. I did...kinda sneak a peek at your brother. Don't be mad." Kyoka confessed. "It helps that he's a pretty nice guy, too. I hope he doesn't become a huge slab of meat, though. A guy who's all this - " She pointed at her bicep " - has none of this - " She touched her forehead " - and usually doesn't have much of this." She pointed between her legs.

"Hahaha!" Izumi giggled. "Izuku's not a steroid user. Plus he and I are kinda small. I don't think you have anything to worry about."

"Still. Guess I wish for more lean than buff builds out there. He can have thick thighs and glutes, I guess..." Kyoka paused and looked over at Izuku and Momo. His body shape hadn't changed, and Momo was still flailing helplessly against a washing machine. Seemed she hadn't heard her "wish."

"So you want my brother to be like a femboy?" Izumi asked.

"Uh...what's that exactly? Just sounds like a girly guy."

"It basically is. Um...let me show you." Izumi leaned over conspiratorially and fished out her phone. A quick google search and Kyoka was face to face with fat bubble butts, thick thighs, and adorable pouts and grins on feminine male faces.

"W-Wow. Izuku's face is kind of like this already..." She averted her gaze and her earjacks looped around her fingers.

"I might've told him once that if he worked his gyatt he'd be more popular," Izumi added.

Way more. Kyoka looked back at Izuku and Momo again. Huge boobs. Feminine boys. Muscles. Squishiness. What the hell? Am I just into everything? No. No I'm not into muscly hunks. I'm into...femininity? Kyoka bit her lip and gestured for her to put the phone away.

"I don't want you to feel pressured about what Momo said," she told Izumi. "Yeah. I...heard everything. She's a little - well, a lot - open sexually. She kinda wants me to let loose in that department, and I guess everyone else too. But I won't try to pressure you into any of that stuff."

Izumi blushed, swallowed, then pulled out the words she was almost scared to say. "Would you want it, though? A bunch of girls all over you, I mean. I've always wanted to try a cuddle pile. It could be nice."
