Wading Walk

Little couple story reward featuring some MHA cuties and some VERY watertight panties. Hyper wetting ahead~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

“T-Tsu, I can’t hold it for...t-too much longer…”

“If you feel too full, just let it Ochaco! They’ll hold, you know. And I’ll even go with you...”

“Maybe just a bi...NO, NO NOT YET I CAN’T!!!”

Taking what seemed to be just a simple walk through the park one evening after school, Tsuyu Asui and Ochaco Uraraka were actually hiding a joint secret within their bladders.

Utterly full from having held it since the morning, the two heroes in training were about ready to burst!

While Tsuyu seemed to be a bit more used to the uncomfortable fullness though, the poor gravity-altering gal Ochaco thought she was about to flood her panties at any moment now.

But oddly enough, the two girls were prepared for just an occasion…

“My stomach is so cramped up I can hardly walk...I-I really need to gooooo!”
Ochaco squealed quietly as her hands shot between her thighs. She squirmed so nervously passersby were starting to get curious at the spectacle.
But even with an increasingly embarrassing scene forming, the girl had one source of comfort in her best friend…

“Just try not to think about it! Relax, take in some deep breaths, and let it all out.
I do it all the time, I promise they’ll keep it all in! And nobody even bats an eye after a while.”

The frog-like girl spoke as soft and calm as always, keeping one arm around Ochaco as she whimpered from the uncomfortable tightness in her lower region…

The desperate girl trusted Tsuyu more than anyone, of course! But even then, to remove the mental blocks and just start peeing herself in public was...hard.

Even if she wanted to, she wasn’t sure she’d be able to make it happen so easily!
But after a couple of steps more, it was clear that she’d have to deal with it right here and right now!
And so, leaning in on Tsuyu’s shoulder with a shaky breath and a flushed face, she whispered quietly…

“I-I’m...I’m going…”

prrrrrRRRSSSSSSSHHHHHHLRRRRR-

Starting with a painfully slow dripping from her tightly clenched womanhood, slowly but steadily the dam burst.The trickle turned to a stream, then a river as fresh warm pee spread around her crotch and butt.
The light pink flush upon Ochaco’s face turned to a bright, burning red as it happened, just KNOWING that it was leaking everywhere for all to see. But surprisingly…

“See? There’s absolutely nothing to worry about, Ochaco. These panties hold it aaaall in~”

As she let the flow go full-force now, Tsuyu pointed out to the steadily relaxing and blissfully sighing Ochaco how she couldn’t feel a single drop run down her legs.

Instead, the white satin panties she currently wore simply expanded, filling with a pool of piss that kept her hips fully submerged.

Ochaco wondered just what Tsuyu had in mind when she gifted her these underwear, but thinking back on the prompt of holding it for an entire day...it made sense!
These panties weren’t just any old regular panties!!!

“T-Tsu!!!
It’s really not leaking, I keep going but nothing’s coming out!
M-My panties just keep growing!!!”
Totally amazed by the sheer strength and security of these panties, Ochaco’s embarrassment was steadily being drowned out by curiosity.

The green-haired girl smiled at this, giving a slight croak of amusement at Ochaco’s adorable demeanor.

“Told ya! I’d never let you do something like that just to embarrass yourself.
...and I definitely wouldn’t let you do it alone either~”

With this, Tsuyu fully embraced Ochaco as she spread her legs a bit and let her own flow finally go free.

Much more used to doing this in her spare time, Tsuyu’s panties instantly began to swell up with the same steamy surge, though seemingly with much louder splashing than Ochaco’s.

The first to wet herself stared down at Tsuyu’s butt as she went, and saw it actually begin to bulge out as the slightest hint of her light green panties peeked from under her skirt.

“Ah!!! Tsu, y-your underwear...they’re getting too full!!!
I can see them, even under your ski-”

“Aaaaahhhhh...you worry too much, Ochaco~
It’s okay to show off a little, isn’t it? Especially when it feels soooo good…”
Tsuyu muttered softly, growing oh-so relaxed as she let loose. Her lithe little body slumped in Ochaco’s arms, her own wrapped around her waist and allowing her hands to playfully tap at the similarly expanding white panties.

“A-Ah!!!
Don’t tell me I’m showing mine too, o-oh no…”
The girl whispered shamefully, now tugging at her own skirt trying to cover the ever-filling underwear.
They hardly even showed underneath her black tights, but for someone who’d never done such things in public she’d simply panic regardless.
But even as her cheeks burned hot and heart raced a mile a minute, she had to admit...it felt great.

As the two schoolgirls studio there, arm in arm and bladders unleashing a seemingly ungodly amount of piss by this point, Ochaco nervously muttered to Tsuyu as she noticed an odd stare or two…

“U-Um...Tsuuuuu?
How...long is this going to last?”

“Until it reaches your ankles, typically~? Maybe longer...the tea we had at lunch really does some amazing things…”
Tsuyu responded dreamily, her own panties now dipping down about mid-thigh, still entirely leakproof amazingly enough.

Ochaco sighed at the realization of just how much more intense her need to go was after lunch, wondering for a second why Tsuyu was so intent on going to these lengths.

But as she looked down to see the sweet, simple classmate of hers nuzzle into her soft chest, she began to understand a couple things about Tusyu...or her girlfriend, as she should say…

“I-I think I get it...a-alright...I can do this.
For you, at least~”

Resigning herself to the humiliating, yet oh-so relieving feeling, Ochaco just let herself flood her panties to their full capacity, enjoying the warm, bloated-bottomed moment the two shared without a care.
And when their panties would finally reach their ankles and the sun was setting nice and low, empty of bladder and full of heart the two continued their trek home hand in hand…

“Thank you for doing this with me, Ochaco...I can’t wait to show you how much of the other stuff they can hold!” Tsuyu teased with a small ribbit, just adoring the way Ochaco tensed up in her sloshy undies. But even at the thought of unloading from the back...

“O-Oh...c-c-can’t wait, hehehe…” she responded with a light blush and small smile, feeling just a tinge of excitement downstairs as she let out the soft poot into the water-balloon she’d made around her hips.

She might just have had to do it early~
