Aiko's Explorations by Imouto Kitten

Chapter 2: A Desperate Workout

Having no pressing obligations for the rest of the morning, Aiko decides 
she'll take a run through the park as she hangs her towel over her 
bedroom door and retrieves a matching set of tank top and track shorts 
from her closet. Not sure she could take fabric rubbing directly against 
her girlhood after the sexual frustration of the morning thus far, the 
blunette foregoes underwear as she dons the pale blue ensemble before 
pulling on matching ankle socks.

Knowing the importance of hydration, especially during long runs, Aiko 
exits her room and returns to the kitchen where she retrieves a large 
sports bottle and fills it from the kitchen tap. Sitting the bottle next 
to the front door, Aiko does a series of stretches to limber up, showing 
off her well-toned calves and making the somewhat loose clothing press 
against her in a way that hints at the svelte body beneath.

Deciding her body is ready for her real workout, she slides on her 
sneakers, pulls the shoulder strap on the sports bottle over her head, 
and exits the apartment, making sure to close and lock the door behind 
her as she starts jogging in the direction of the park.

As she hits her stride, Aiko revels in the feeling of her favorite 
physical activity, her world narrowing to the thump of her heart, the 
smack of rubber against concrete and asphalt, and the wind rushing past 
her. The only interruption in her rhythm is her occasionally bringing 
the mouthpiece of the sports bottle to her lips for a drink, and though 
her bladder pangs with every additional bit of fluid she consumes, she 
barely notices, her mind focused on not running into anything, 
regulating her breathing, and resisting the near primal urge to break 
into an all out sprint, constantly reminding her body that she's not in 
a race and needs to conserve her energy for the trip home.

The blunette's runner's trance is only broken when she brings the bottle 
to her lips, but instead of a mouthful of refreshing water, all she gets 
is the hollow sound of a straw sucking at an empty container. Realising 
the bottle is empty, Aiko comes to a stop, and it's at this moment that 
her bladder finally manages to catch her attention, throbbing almost 
violently as it wishes to throw obscenities at it's owner for not going 
before leaving home.

Shamelessly grabbing at her girlhood through her shorts, Aiko glances 
around and recognizes the wooded, dirt path she's currently standing on 
to be clear on the opposite side of the park from the public restrooms 
and water fountain, the nearest place she can refill her water bottle 
and empty her bladder in a proper receptacle. It's a long walk, but Aiko 
is confident in her strength, but she's also reminded of the incident in 
the kitchen and realises the current location is remote enough to 
provide privacy, but not so remote that there would be no risk of being 
caught if she were to do something naughty.

Giving into her desire to recapture the thrill of possibly being caught 
she experienced earlier that morning, Aiko squats down on the path, her 
bladder screaming in protest that she didn't pull down her shorts in the 
process. This shift in position allows a gentle breeze to blow up her 
pant legs to brush against her pantiless girlhood, sending shivers up 
the blunette's spine and increasing her arousal.

Sliding a hand down the front of her shorts, Aiko wastes no time as she 
plunges not one, not two, but three fingers all the way to the third 
knuckle within her young passage. Curling her fingers into her g-spot 
and grinding the heal of her palm against her clit, the athlete starts 
to moan softly as visions of what might happen if she were caught dance 
across her mind's eye.

She imagines a horny teenaged boy or a lolicon of a dirty old man coming 
across her and taking advantage of her distracted state to push her in 
the dirt, yank down her shorts, and pluck her cherry before she can try 
to fight him off as well as images of a shy girl being frozen in shock 
at the sight of a girl masturbating and thus defenseless as Aiko pins 
the girl against a tree and starts roaming her hands over her body.

As Aiko continues to play with herself, largely ignoring the pounding of 
her piddle pot, her fantasies growing more and more lewd by the second, 
she can feel herself building to what promises to be one of the biggest, 
if not the biggest climaxes of her young life.

And just when she feels on the verge of a satisfying release, she hears 
a familiar voice penetrate her vulgar thoughts, though she doesn't 
immediately recognize the speaker or their words.

Too close to stop now and spurred on by the fact she's been spotted and 
that a witness will soon be close enough to see what she's doing if they 
aren't already, Aiko increases her pace as she drops to her knees and 
uses her free hand to support her weight. Her body grows ever tenser, 
both from the quickly approaching climax and in preparation to keep her 
pounding, pent-up piddle from pouring out in a powerful, pant soaking 
stream and pooling in a mud puddle beneath her.

Then it happens, the coil of tension snaps and the blunette's mind goes 
blank as an orgasm beyond any she's had previously courses through her 
svelt frame. It is only reflex that allows Aiko to drop to her elbow and 
safely roll on to her back instead of collapsing ungracefully into the 
dirt face first as her entire body convulses, and she nearly draws blood 
as she bites her lip in an attempt to not scream.

As she regains her senses and catches her breath, Aiko feels her golden 
liquid gushing into her palm, her bloated, overburdened bladder having 
taken advantage of her brief lapse in consciousness to attempt betrayal. 
She nearly crushes her own fingers in the process of pressing her pelvic 
muscles together to prevent anymore pee from pouring out, the 
personification of her protesting piddle pot pouting pitifully at having 
her plans foiled.

As her eyes flutter open, they are met by the worried gaze and 
distinctive bangs of Mutsumi Kudo, her fellow athlete dressed in the 
white t-shirt and red buruma of Misora First Elementary's gym uniform 
instead of her usual ensemble of a teal blouse and blue skirt.

Registering that Mutsumi has been talking but that she hasn't processed 
a single word, Aiko asks unintelligently, "Huh?"

"I asked if you were okay." replies the brunette, her tone of someone 
chiding another for pushing themselves too hard, "Your face is all red, 
I noticed your water bottle is empty, and it looked like you were having 
a seizure just a minute ago." At this, Mutsumi brings the spout of her 
own water bottle to Aiko's lips, and much to her bladder's protest, the 
blunette takes a sip of the refreshing liquid to give herself a moment 
to think.

Looking over herself, Aiko is drenched in sweat, more than would be 
normal given the weather and her usual workout, but nothing anyone is 
likely to question. Glancing down, her hand is still down the front of 
her shorts, and while she can see tell tell signs of her leak having 
stained the pale fabric, her crotch is no more soaked with pee than the 
rest of her clothing is with sweat. She can still feel her girlhood 
tingling both from arousal and from desperation, a longing to have 
another's hand replace her own still strong even as she fears removing 
her hand will open the flood gates completely.

Aiko is the fastest sprinter and best all around female athlete in 
school, but Mutsumi is queen of the wrestling ring, able to best even 
many of the boys in a fair match and yet Aiko can't help wondering if 
she could catch the other girl off guard enough to have a chance of 
pinning her.

Realizing any attempt to best the aspiring pro wrestler would probably 
end with the blunette pinned beneath the brunette, the other girl 
sitting atop the Osakan's overfilled bladder and squeezing it until it 
pops as she lectures about proper sportsmanship, Aiko shakes her head in 
an attempt to clear it of lewd and potentially humiliating thoughts as 
she uses her free hand to accept Mutsumi's offer to help her to her 
feet.

"Thank ya fer checking on me." says Aiko as the other girl brushes dirt 
from the blunette's track clothes, "I must've been pushing myself too 
hard to collapse like that."

Mutsumi seems convinced of her mistaken interpretation of events, and 
Aiko is about to let out a sigh of relief when the brunette asks, "Why 
does Ai-chan have a hand down her shorts?"

Cursing mentally for not pulling her hand away sooner, Aiko quickly 
realizes a less embarrassing truth she can reveal to conceal the more 
embarrassing truth, "I really need to pee!"

Mutsumi shifts her weight from foot-to-foot before offering, more shyly 
than is normal for the wrestler, "If you want to... I could stand watch 
while you go behind a tree and take care of that."

Glancing down, Aiko notices a slight bulge where the hem of Mutsumi's 
t-shirt meets her buruma in front and can't help wondering if coming 
across the blunette interrupted the other girl's efforts to reach the 
public toilets in time or if Aiko's own announcement had brought the 
wrestler's own overfilled bladder to her attention.

Aiko also notices that Mutsumi is standing right in front of a tree as 
the brunette brings her attention back to their conversation, "So, what 
will it be, Ai-chan?"

Deciding that being too forward might just scare the other girl off, 
Aiko brushes off the offer, "Nah, I'll be fine until we reach the 
toilets." Before casually stepping behind the brunette and pressing her 
palm against Mutsumi's lower abdomen as she teasingly adds, "But I could 
stand watch fer ya if Mutsumi-chan can't last that long." Dropping to a 
whisper, Aiko continues, "Or we could do it together."

Blushing slightly, Mutsumi replies, "That's okay, I don't need to go at 
all." the firm bulge Aiko can feel through the brunette's clothes makes 
the lie obvious, but the blunette decides to let her fellow athlete be 
stubborn even as she refuses to give up herself.

Aiko lets go of Mutsumi as the pairr resume their trek through the 
park's more scenic areas, both of them walking now, ostensively to avoid 
jostling Aiko's bladder unnecessarily, but the blunette can tell her 
workout partner is in no better shape in this regard, Mutsumi's strides 
rather irregular for an athlete and growing more erratic clear signs the 
wrestler isn't paying attention to her movements the way she normally 
would.

Though their exertion is greatly reduced compared to earlier, it is 
still a very warm day, so the pair continue taking additional sips of 
water, now taking turns from Mutsumi's water bottle, Aiko hesitating 
briefly at her bladder screaming in protest every time the nozzle comes 
to Aiko's lips, but the blunette can see just as much hesitation 
whenever it's Mutsumi's turn to drink.
	
As they approach the bend that will put the park's facilities within 
sight, Mutsumi suddenly bends double, her hands clamping over the crotch 
of her buruma as she falls to her knees and nearly kisses the dirt path. 
The wrestler hisses something Aiko can't make out through gritted teeth 
as the fabric peaking out from between the brunette's parted thighs and 
splayed fingers turns a darker red.

It's obvious to Aiko that her fellow athlete just sprung a leak and her 
own bladder begs to follow suit, but between Mutsumi's compromising 
position with her butt sticking in the air and the way the brunette's 
trembling makes it look like she's swaying her hips seductively, Aiko 
isn't sure whether to be aroused or concerned.

Realizing an opportunity to do naughty things to Mutsumi while 
maintaining plausible deniability, Aiko Kneels behind the prone girl, 
nearly leaking herself in the process. Wrapping her arms around the 
brunette, the blunette helps the other girl to her feet before clamping 
a hand over the crotch of the wrestler's buruma.

"The toilets are just around the corner." Whispers Aiko into Mutsumi's 
ear as she rubs her fingers over the trembling girl's panty and buruma 
clad girlhood, eliciting a low moan and moderate blush from the 
wrestler. Mutsumi's plump little rump pressing against Aiko's lower 
abdomen adds pressure to the blunette's bladder and she has to clench 
her every muscle as a leak of her own escapes into her track shorts, but 
the close, nearly intimate position increases her arousal just as much. 
If Mutsumi notices the effect she's having on the Osakan, she makes no 
comment.

The pair resume their trek towards relief, their pace slowed even 
further as Aiko holds Mutsumi upright even as she leans on the wrestler 
in turn.

After what feels like an eternity to Aiko's tormented, throbbingly taut 
tinkle tank, the pair reach the gray stone building that houses the 
public toilets and push their way through the wooden door to the girls' 
room.

Aiko isn't sure if she can make it the last few feet to a stall and get 
her shorts down before the dam breaks completely, and while Mutsumi has 
been quiet since Aiko helped her to her feet, if the wrestler's 
trembling and the rock hard bladder bulge beating against the blunette's 
forearm are any indicator, the brunette is in no better condition.

And to make matter's worse, there's a part of Aiko that wants to forget 
about the impending floods and just have her way with Mutsumi.

Throwing caution to the win, Aiko spins Mutsumi around and crashes her 
lips against the other girl's. The blunette cups a hand over each of the 
brunette's half-moons, the preteen pair's pulsing, protruding piddle 
pots pounding powerfully in perfect sync as they're pressed between the 
girls, pints of pent-up pee praying permission to pour forth. Mutsumi is 
initially shocked, but soon leans into the kiss, parting her lips to 
invite Aiko's tongue to a wrestling match as she wraps her arms around 
the blunette.

As their tongues fight for dominance, Aiko feels her golden liquid start 
to flow, but makes no attempt to halt it as she pushes Mutsumi into a 
stall, the brunette offering no resistance. Pulling Mutsumi's buruma and 
panties to her knees, Aiko briefly glides her palms over the wrestler's 
sweat slickened skin before diving between her thighs and sliding a 
finger as far up Mutsumi's passage as possible, swallowing the moan that 
results from this action.

Feeling her legs about to give out, Aiko briefly wonders how things 
would play out differently in a public bathroom with Japanese toilets 
before making Mutsumi sit and straddling the brunette's lap. Though 
she's not recieving much stimulation herself, Aiko is enjoying the way 
Mutsumi squirms under her ministrations too much to care all that much 
about the fact she's wetting her track shorts, and if the way the 
brunette is moaning into the blunette's mouth is any indicator, the 
wrestler isn't all that bothered that she's being peed on.

After some time, Aiko hears a steady tinkling join the occasional drip 
of her pee oversaturating her shorts and managing to find an 
unobstructed path, and flicking a finger on the hand playing with 
Mutsumi out is met with the brunette's own stream. Aiko increases the 
pace at which she finger fucks the brunette, determined to make the 
other girl cum before she's done emptying her bladder.

Just as Mutsumi's stream starts to slow, she breaks the kiss to let out 
a scream of pleasure as her insides tighten around Aiko's finger, nearly 
crushing the digit.

The two sit in silence for some time before Mutsumi recovers enough to 
exclaim, "That was amazing, Ai-chan!"

Smiling widely, Aiko replies, "Glad ya liked it." even as she debates 
what to do next.

Standing up, Aiko glances down to see that Mutsumi's clothes are mostly 
untouched, though the brunette's lap glistens with the remnants of the 
blunette's accident. The sight of the half-naked girl is almost more 
than Aiko can resist, but she manages to tear her eyes away from where 
the other girl's well toned thighs conceal her unclothed girlhood to 
examine her own shorts.

The crotch and inside thigh of Aiko's track shorts are completely soaked 
and have a green tinge to them that makes it clear that the wetness is 
from pee rather than sweat or from spilled water.

Leaving the stall, Aiko locks the door to the outside and wets a few 
paper towels in the sink before returning to Mutsumi and offering, 
"Would ya like me ta wipe yer thighs of my pee?"

"Sure..." replies the brunette, blushing as she parts her thighs, her 
panties and buruma falling around her ankles in the process. As Aiko 
washes Mutsumi's thighs, its all the blunette can do to resist the urge 
to do more, though she still smiles when a swipe to clean the brunette 
of her own pee makes the wresler shiver.

Done with the cleaning, Aiko apologizes, "Sorry fer peein' on ya." as 
she stands up, heading to the sinks, I'm gonna try to rinse out my 
shorts some."

Standing herself and pulling up her bottoms, Mutsumi replies, "I think 
I'll be good with-" only to go silent as the blunette drops her shorts 
and reveals her lack of underwear. "Ai-Ai-chan isn't wearing panties!" 
cries the wrestler as her face goes crimson.

Shaking her ass as she bends over to pick up her sodden shorts, Aiko 
replies, "Yeah, decided ta go commando today. Do ya like what ya see?" 
Not hearing a response by the time she drops her shorts in the sink and 
starts the water running, Aiko asks, "How about ya return the favor and 
clean me up while I'm working on my shorts?"

Snapping out of her shock, Mutsumi replies, "Su-Sure." as she wets a few 
paper towels and kneels behind the blunette.

As Aiko rinses and wrings out her shorts several times in an attempt to 
get them clean enough to pass off the remaining dampness as sweat, she's 
a bit disappointed Mutsumi doesn't try to do anything beyond cleaning, 
though she still finds the experience nice and figures they can have 
more fun after lunch.

Giving her shorts a final wringing, Aiko pulls them back on before 
turning to Mutsumi and asking, "Whacha wanna do for lunch?"

"I had originally plan to meet up with Hasebe-kun after my jog..." 
replies Mutsumi, trailing off at the end.

Sensing that Mutsumi is torn between continueing her chance encounter 
with the blunette and not standing up the boy Aiko suspects the brunette 
harbors a crush on, Aiko debates what to do.

As tempting as it would be to crash her fellow athlete's date and try to 
arrange for the boy to pop both their cherries, Aiko decides parting 
from the wrestler would give her some time to plan the afternoon's fun.

"How 'bout ya meet up with Hasebe-kun like ya planned and then stop by 
my place later?" Asks Aiko, pulling the other girl into a hug, and 
cupping a hand over the wrestler's buruma-clad girlhood before adding in 
a husky whisper, "and then we can continue our fun."

"Su-sure!" replies Mutsumi, blushing furiously as she wriggles out of 
Aiko's grip.

The pair exit the bathroom and are soon headed towards their respective 
destinations.
