Aoi hummed a catchy tune to herself as she diligently fastened the strings of her yellow bikini top, wanting to avoid any possible wardrobe malfunctions during her daily laps around the academy pool today. She tied them tightly enough so that they wouldn't come loose at all before slipping her fingers inside her swimsuit, making certain that everything felt nice and snug. This included her large breasts, which jiggled with each inspective graze of her fingers. Once she felt comfortable, Aoi let out a happy giggle and gingerly closed her locker door shut. She then reached down to grab her towel off the nearby bench, not expecting anything unusual to happen since she was all alone in the girls' locker room.
Right as Aoi was about to grab the cloth, however, a loud bang, almost like a gunshot, suddenly rang out from behind the door leading to the pool. This startled the swimmer, who stared at the door in confusion before uttering, "W-what the heck was that…?!" and making a dash towards the pool to investigate the noise.
"STUPID PIECE OF JUNK!" Miu cried as she, dressed in a leopard print bikini that barely covered anything at all, smacked her latest invention, which had been short circuited by the water. Despite the fact she'd been working on a device to help her and others swim faster, she'd somehow forgotten to account for the water itself. "Come on, you—"
As she was about to disassemble the device to examine it, it suddenly blasted off, dragging the inventor into the water as Aoi entered the room, hearing Miu's screech as she was dragged along the pool's surface, forced to hold on for dear life.
Aoi was quickly rendered speechless at the rather comical sight of her classmate getting yanked across the pool, with Miu shrieking in terror all the while. It was one of those moments where, even if she told someone what had happened, they wouldn't have believed her at all, and honestly, Aoi could hardly believe what she was witnessing herself, even as she made a beeline towards the edge of the pool.
"Oh my god! Miu!" Aoi screamed, blue eyes fixated on the spectacle playing out before her.
"HUH? WHOZZAT?!" Miu cried, attempting to see who had come in. In doing that, however, she lost her grip on her device, which went careening straight towards a corner and struck it. Miu was thrown from the machine, which also snagged her bikini top straight off her body as she went flying into the water. Her entire front half slapped the water hard, and she let out a small, pained gurgle before she began to sink.
Aoi instantly cringed at Miu's faceplant, which she had no doubt hurt quite a bit. However, her feelings of pity were quick to disappear when she realized that Miu wasn't coming up for air. Only bubbles were floating to the surface.
"Crap, crap, crap! What do I do?!" Aoi panicked, bouncing from foot to foot. While she did know CPR, she was nowhere near as qualified to resuscitate a drowning victim as Hope's Peak's resident Ultimate Lifeguard, who was unfortunately nowhere to be found. However, with few other options and Miu's life on the line, Aoi inhaled as deeply as she could and swiftly dove underwater after the drowning inventor.
Miu continued to sink until, in whatever consciousness she had left, she was aware of someone wrapping their arm around her waist and pulling her up and out of the water. Her breasts sagged down to either side thanks to pesky gravity as her waterlogged lungs still couldn't quite breathe.
Heedless to Miu's state of toplessness in her rush to save her, Aoi immediately began to do chest compressions, placing both hands slightly between her underboob to do so. She mentally counted each compression she did while chanting, "Come on, come on! Breathe, Miu! Don't give up on me!" After around twenty seconds of compressions, the inventor's eyebrows started to twitch, but the blonde still remained mostly unresponsive. With little options left, Aoi steeled her nerves as she brought her lips to Miu's and blew as much air as she could into her lungs, blushing softly as she realized that she had technically just given this girl her very first kiss. The fact that she fully enjoyed how soft Miu's lips felt only made her feel even more embarrassed.
Thankfully, it didn't take much for Miu to regain consciousness after that, as she violently spat up the water a moment later and gasped as she sat up, bonking Aoi in the head and leaving both groaning. Once she had recovered, both from her near-drowning and her momentary headache, Miu met Aoi's eyes and began to cry uncontrollably. "M-m-my herooooooo!!!"
"W-woah!" Aoi gasped as Miu suddenly lunged forward and squeezed her tightly, burying her face into the swimmer's neck as she openly wept in front of her. Her blush deepened as Miu's enormously soft breasts pressed against her own. Despite her shock, though, Aoi was quick to hug the girl back, smiling as she gently patted her back and awkwardly reassured, "T-there there. You're, um…you're safe now, Miu. I got you. You're safe…"
"I-I'll love you forever!!" Miu cried with such a genuine expression that Aoi's blush immediately deepened.
"O-oh…um…thanks?" Aoi slowly replied, feeling her cheeks radiating a pleasant warmth at Miu's admission. She waited a couple seconds for Miu's sobbing to lessen slightly before clearing her throat and asking, "So, uh…Miu? I gotta ask…what exactly were you doing in here?"
"Oh…Well…" She hesitated at first before sighing. "I was…trying to invent a water scooter to help people swim, since I…" She paused again, "I-I can't…"
"You…don't know how to swim?" Aoi repeated as she slowly processed this information.
"D-don't make fun of me, okay?! I just…never got the hang of…" Suddenly, Miu stopped talking. Aoi wasn't sure why until the blonde looked down and screamed as she covered herself. "WH-WHY ARE MY TITS OUT?!"
Aoi felt her face turn bright red as, despite Miu's efforts, the inventor's enormous breasts jiggled enticingly from her sudden movements. Her blush only grew when she realized that she was staring at them like an idiot, prompting her to partially tear her eyes away from Miu's mountains and stammer out, "I-I don't know! Your bikini must've gotten untied and came flying off somewhere!"
"Do you see it anywhere?" She asked as she turned towards the pool, but while her invention was in pieces, the bikini top was nowhere to be seen.
"N-no, I don't see it nearby." Aoi responded as she looked around as well, finding nothing. "Hold on, lemme check underwater real quick." She said, swallowing a quick breath before leaning down and submerging her face underwater, which helped to cool her warm cheeks and inadvertently give Miu a good side view of her jiggly ass cheeks. Alas, she didn't see any trace of Miu's bikini, causing her to frown as she popped her head back above the water. "Sorry, Miu, but I didn't see your top down there." She informed, shaking her head.
"Aw man…" Miu lamented as she crossed her arms, and then glanced at Aoi. "W-well…I guess it's not so bad, since we're both girls." With that, she made the decision to allow her arms to drop. "J-just don't stare too much, okay?"
"…You're really pretty, Miu." Aoi suddenly blurted out without thinking as Miu's nipples became exposed.
"I-I…W-well…Thank you, hehe…I-I mean, it's only natural you'd think so!" Miu said, some of her usual spunky attitude returning even though her face was still very red at Aoi's compliment.
Miu's spark of enthusiasm prompted Aoi to giggle softly alongside the inventor, even as her blush persisted. When their laughter died down, Aoi started to play Miu's earlier admission back in her head, during which she got an idea.
"You know, Miu…If you'd like, I can teach you how to swim." Aoi offered with a soft smile.
"You…you'd do that?" Miu asked with hopeful eyes.
"Sure!" Aoi replied, getting some of her own spunk back as well as she excitedly pumped her arms to her bountiful chest. "I'm always down to teach someone how to swim! It's lots of fun once you get the hang of it!" She encouraged before scratching at the back of her head nervously. "Plus…it'd be pretty bad if you had another accident while I'm not around…hehe…"
"Right…Well…okay, then. What first?" Miu asked, unsure of where to start.
Aoi let out a hum as she thought about what to start Miu off with. Butterfly stroke? No, too advanced. Freestyle? No, too tiring. Hmm…"Why don't we start with floating, first?" Aoi suggested after a moment.
"Floating?"
Aoi nodded. "Yeah! You can't swim unless you learn to float first! I…kind of learned that the hard way when I first started swimming." She gave out another awkward chuckle.
"Okay. How do I…float, then?" Miu asked, a little confused.
"It's easy! Here, I'll show you!" Aoi said before shoving off into the shallow end of the pool. She held out her hands, gesturing for Miu to join her in the water. "Come on in! The water's nice and warm!"
Miu was clearly hesitant, but eventually nodded and slowly climbed into the water, almost immediately grabbing onto Aoi for support, even though her feet were firmly rooted to the floor.
Aoi once again blushed at Miu's closeness, although this time it was accompanied by a soft giggle. "Don't worry Miu, I gotcha." She assured the inventor. She waited for Miu to acclimate to the water's temperature before saying, "I'm gonna carry you out a little deeper now, okay? Just relax your body and hold on tight, got it?"
"O-okay!" Miu said as she tightly clutched the girl's arm, accidentally sliding it between her breasts.
Immediately, Aoi gasped as her arm was smothered in heavenly softness, the likes of which even surpassed her own huge boobs. Her blush deepened, and she had to physically bite back the urge to moan as she slowly carried the scared inventor into the deeper end. Due to Miu's taller height, she ended up losing her footing first, but it wasn't too big of a problem for her since she was perfectly capable of staying afloat while holding onto another. But when Miu lost her footing, on the other hand…
"A-AHHHHH!" Miu screamed as she scrambled against Aoi, and began to panic, nearly scratching at the girl, and further squishing her breasts against her body as weightlessness overtook her completely.
"W-woah! Easy, Miu! Easy!" Aoi quickly urged, once again gasping as Miu's naked breasts pressed into her arm. This time, she could feel Miu's nipples poking her skin, causing her to shudder even as the blonde's panicked squirming threatened to send them both under. Thinking fast, she embraced Miu tightly and assured, "I've got you, okay? I've got you. Just relax. You're not gonna drown, okay?"
"I…I…O-okay…" Miu uttered while taking a deep breath. "I…I'll try and…relax now…"
"There we go…That's a lot better." Aoi said, smiling warmly as Miu finally calmed down and began to relax in her arms. At the same time, she couldn't help but fondly think that Miu looked quite cute when she wasn't cussing up a storm, but that was a gay question for later. She could already feel the girl's legs making small kicks underwater, almost instinctively, which was a good sign that they were ready to continue with their lesson. "Okay…I'm gonna move on to having you float on your own now." Aoi said, earning a small nod from Miu. "I'm gonna slowly let go of you, and when I do, I want you to kick your feet and paddle your arms around in a circle as soon as I let go. Oh, also, remember to stay relaxed. That's the most important part." She finished explaining, shooting the girl a reassuring grin as she added, "Can you do that for me, Miu?"
Miu nodded with determination, even if she was still scared of sinking.
Seeing this, Aoi nodded back before slowly beginning to uncouple herself from her clingy passenger, admittedly feeling a little sad that her breasts were no longer touching her. She made sure to hold her arms beneath Miu, just in case something went wrong.
Miu did as Aoi instructed, and her breasts bobbed above the water as she soon found herself floating effortlessly. "O-oh my god! Oh my god I'm doing it!"
"You are! You're floating, Miu!" Aoi gushed with a giggle, feeling like a proud mom at the inventor's achievement. She retracted her hands and watched endearingly as Miu started to cautiously explore her newfound ability to float, using her arms to push her body backwards and forwards and side-to-side, getting progressively more brave with each paddle. She even took an experimental breath and dunked herself underwater for a moment, resurfacing a couple seconds later with an ecstatic smile. Before long, it was like the girl had always known how to float, which made Aoi extremely happy to see.
At the same time, though…she once again found her gaze focused solely on Miu's buoyant breasts, which continued to bob along the surface of the water. Aoi found it increasingly harder to look away from them, even feeling a not-so-unpleasant tingle appear between her loins that made her want to scratch at her nether regions in addition to her warm blush.
"This is…incredible! And…honestly not as hard as I was expecting." Miu said with a laugh of pure joy. She lifted herself out of the water before allowing herself to fall back down and quickly pulled herself back to the surface, her large breasts swaying this way and that.
A sharp gasp escaped Aoi as she watched Miu burst forth from underwater, her gorgeous body completely glistening with pool water as she whipped her silky blonde hair back. And all the while, she continued staring hard at Miu's jiggly breasts, feeling the urge to start rubbing her pussy growing increasingly harder to resist, especially when faced with such a beautiful girl like Miu, whom she was certain she was beginning to crush on.
"Y-yeah! Like I said, it's easy once you get the hang of it." Aoi stammered out in an attempt to distract herself. "But…I gotta say, you're kind of a natural at this swimming stuff, Miu. You picked up floating a lot faster than I thought."
Miu swam up to her and smiled. "Maybe I just had a good teacher!" She said, smiling at the other girl.
Aoi felt her cheeks turn bright red at Miu's kind words. "A-aw, thanks…" She said bashfully.
"This is actually a lot of fun! Shit, if I knew how easy it was to swim I would've gone swimming all the time! This fuckin' rules!" Miu exclaimed joyfully as she began to swim more freely, albeit in an amateurish, slow way, with her breasts bouncing up and down, side to side, moving above and below the water with each movement she made.
"Oh my god…!" Aoi breathed out, helpless to resist the splendor of Miu's breasts as she started to get VERY turned on by them, and by extension, Miu. Her mind was quickly beginning to picture Miu in all manner of lewd scenarios, from groping them to burying her face between them to imaging they way they might jiggle during underwater breathplay. Nothing was off the table, and before Aoi could fully process what she was doing, she subtly brought a hand to her lower lips and let out a soft moan as her face grew flush with color, heedless of whether or not Miu would notice her arousal.
"Hey, wanna race? Bet I could beat you now that I've got the hang of swimming!" Miu asked before pausing as she looked over at Aoi. "Er…What are you doing?"
Aoi's eyes instantly snapped open at Miu's voice as her cheeks also grew tomato red. She quickly retracted her hand and stammered out, "N-nothing! Nothing at all! Just, uh…enjoying the water! Yep!"
"You're…Oh my god…" Miu said and smirked. "I didn't know you were into that, too!"
"I…what?" Aoi asked, confused but also intrigued by what Miu was implying.
"What's got you so turned on though?" Miu asked as she swam over, apparently not realizing the obvious.
"T-that's…uh…" Aoi's gaze rapidly flickered between Miu's bouncy tits and her eyes as the girl swam over, making her pussy ache that much more with need. After a moment, she let out a tiny sigh as she uttered, "W-well…It's…It's you, Miu."
Miu stared at her for a while and blinked. "M-me?" She then looked down. "O-oh…You mean my…?"
Aoi shyly nodded as the warmth in her cheeks threatened to leave her with heatstroke. "It's just…I've…never really seen a girl with boobs bigger than mine when they're half nude before. They're…really beautiful boobs, too. I-I mean that."
"Th-that's…Thank you…" Miu was ready to talk the way she usually did when she caught someone staring at her boobs, but Aoi's genuine words made her lose that confidence. "D-do you want to…touch them?"
"H-huh?! T-touch your boobs?!" Aoi nearly choked on her saliva at such a sudden yet tempting offer from Miu, who paddled even closer to her until their breasts were almost touching. "You'd…really let me…?"
"If you want…"
"O-okay then…" Aoi stared down at Miu's floating breasts, quickly feeling her earlier lustful urges return in full force. She swallowed a thick lump of spit before reaching out both hands towards the inventor's superb boobs. She hesitated for a moment, shooting Miu a quick glance just to make sure she was alright with this. When Miu nodded, Aoi proceeded to gently place her hands atop the blonde's enormous breasts, and instantly, she gasped as her fingers were enveloped in an indescribable softness as they sank into Miu's soft boobs, which she lightly squeezed.
It was the first time another person had actually touched her boobs, and Miu was not ready. Immediately, she gasped and ducked her body slightly under the water as her legs almost gave out. "W-Woah…"
"Holy crap…!" Aoi breathed out as she slowly began to fondle her breasts, letting her fingers glide across every inch of bare skin she could see, all while her thighs began to anxiously rub together beneath the water. "These are…so soft! It's like I'm grabbing a handful of marshmallows!" She praised, sparing a quick glance at Miu as she blushed and asked, "Um…D-do you mind if I, um…get a bit closer to them?"
"Gah! Y-you can do…whatever you want…just…keep touching me…!" Miu breathed out as she too could feel her body completely melting in pleasure.
"S-sure…" With Miu's approval, Aoi brought one arm around the blonde and pulled her closer, immediately after which she lowered her head down and nuzzled it right in-between the girl's ample breasts.
"Fuck!" Miu cried. "This is…way better than porn!!"
"You're telling me!" Aoi replied, her voice slightly muffled due to her cozy prison. She could honestly stay like this forever, nestled between Miu's soft, jiggly breasts, finding them downright addictive to touch and grope, even more so than her own chest whenever she masturbated. "If I knew they'd be this soft, I would've asked if I could touch your boobs a long time ago!"
"I…um…Do you…" Miu hesitated, trying to meet Aoi's eyes but lacking the confidence to do so. "Do you…want to do…more?"
Without needing to be asked twice, Aoi looked up at Miu and smiled warmly at her, pulling herself out from between her twin peaks and leaning in close to the point their noses were touching. "I'd…really love that, Miu."
Miu smiled. "We should…probably get out of the pool for that, though."
And they did. They got out and, right then and there, without a care in the world that they could be caught, they made love. Miu and Aoi had always felt they were leaning both ways when it came to love and sexuality, but the short time they spent as one there on the wet floor solidified their resolve that not only did they love women as well as men, but that they loved each other.
And, apparently, big boobs.
Once they were done giving each other a world of pleasure, they laid back together naked on the floor, hands clasped together as they beamed at one another. They giggled at nothing in particular, happy to be with each other there in that moment of ecstasy.
Then the door burst open.
"Oh my GOD! What are you two doing naked and on the floor?!" The Ultimate Lifeguard shouted in disbelief at what she was witnessing, having arrived for her daily laps around the pool as well only to see her classmates nude and in the middle of post-coital cuddling.
"A-AH! Er…W-we were just—!" Miu cried as she sat up.
"I-I was just, uh…teaching Miu how to swim, t-that's all!" Aoi quickly responded, sitting up as well as her face turned red.
"I can't believe you two!" The lifeguard cried, looking as if she might explode at them at any second, only to shoot both of them a pouting expression as she cried, "You two were having sex in the pool and you didn't think of inviting me?!"
Both girls stared in shock at her for a while, neither one speaking. Then finally, they both spoke at once.
"HUH?!"
