Aiko's Explorations by Imouto Kitten

Chapter 8B: A Bound Futanari

The Blonde and Brunette head to the toy case, and after some browsing, 
Mutsumi pulls out a bottle of a super strong, topical aphrodisiac and 
Momoko points out some metal objects that look like a combination of 
free weights and shackles. Momoko is unable to lift them, and even the 
wrestler can barely lift one of them, but they silently agree they'll be 
perfect for tormenting the blunette.

Mutsumi places one of the metal objects on the floor, its black surface 
seeming to absorb all light before securing one of Aiko's wrists in the 
shackle part of it, the weight part making it nearly impossible for the 
blunette to move it without risking a broken wrist. Soon enough, Aiko 
has all four limbs bound in such a manner and is laying on the floor 
with her extremities stretched out in an X, the combined weight pinning 
her to the ground more than even the wrestler could effectively work 
against.

"Kneeling between Aiko's spread thighs, Mutsumi teases, "Now that 
Ai-chan is all helpless..." the brunette uncaps the bottle of 
aphrodisiac and lets the thick, oily liquid pour out over the blunette's 
member. Aiko lets out a scream of sexual frustration as the lube coats 
her futahood, making it throb tremendously, and once the erect shaft is 
completely coated, Mutsumi sticks the nozzle inside Aiko's pussy and 
gives the bottle a good squeeze, making the blunette let out another 
incoherent scream. Mutsumi then pours the rest of the bottle over her 
fellow athlete's torso and limbs before discarding the empty container.

As Aiko's entire body burns in sexual need without any means of 
stimulation, the weights not even allowing Aiko sufficient slack to rub 
her skin against the carpet, Mutsumi turns to Momoko, "Since Momo-chan 
has been so patient, didn't take advantage of me leaving my ass and 
pussy seemingly unprotected, and cooperated with me punishing Ai-chan, I 
think I'll reward you by letting you fuck my ass."

Bending over slightly and sticking out her butt in Momoko's direction, 
Mutsumi spreads her half-moons in invitation for the blonde. Still 
throbbing thanks to her long denied ejaculation, Momoko is quite eager 
to accept the brunette's invitation, grabbing the wrestlers hips and 
hilting herself deep in the brunette's bowels without hesitation.

Tuning the remote to Momoko, Mutsumi increases the length and girth of 
the futahood she's impaled on to the largest she can comfortably 
accomodate before adding a liter to the blonde's bladder as well and 
declaring, "Let's see how quickly Momo-chan can make me cum!"

Accepting the challenge, the blonde reaches around to stroke the 
brunette's member, and upon realizing her girth is too much for Momoko 
to wrap her hands around properly, Mutsumi tunes the remote to herself 
once more and reduces her girth, immediately deciding that, while being 
huge is great when enveloped by a tight twaty, handjobs are much better 
when your girlcock is thin enough to make a fist around before adding a 
liter to her own bladder as well.

"I hope you're watching how much fun Momo-chan and I are having, 
Ai-chan. That is, assuming you have enough sense left to take in your 
surroundings."

Feeling herself nearing another climax, Mutsumi announces, "Wow, 
Momo-chan works fast! Keep this up, and I might have to reward Momo-chan 
even more!"

Doing her best to sound like the dutiful sex slave, Momoko replies, 
"Might Mutsumi-sama remove this cock ring and let me cum at last?"

"Well," starts the brunette, "Since Momo-chan asked so nicely and has 
been so patient, I guess I will let you cum, but not in my butt." 
Pulling off the cock lodged in her ass, Mutsumi walks over to Aiko's 
prone form, taking over from Momoko at stroking her girlcock. "Come on, 
Momo-chan, let's give Ai-chan a cum shower together!" As Momoko takes 
her place opposite the blunette from the wrestler, Mutsumi makes sure 
the blonde's bloated bladder is sealed before reaching a hand out to 
pull the metallic blue cock ring off the yellow apprentice's prick.

Sighing in relief, Momoko joins Mutsumi in furiously jacking herself 
off, both girls pointing their tips down at Aiko, the blunette groaning 
in frustration from extreme arousal and a complete inability to do more 
than turn her head or rub her wrists and ankles raw within her bindings.

Both having been on the verge before they separated, it isn't long 
before both futas are shooting their loads, Momoko producing far greater 
quantity thanks to how long she had been denied release by the cock 
ring. Thanks to being hypersensitive from the aphrodisiac, Momoko and 
Mutsumi's hot seed feels like liquid fire to Aiko, the blunette letting 
out a strangled scream as the other two girls spray her from collar bone 
to pubic mound in fresh semen.

Thanks to how much her climax was amplified by the long period of 
denial, Momoko collapses to her knees by the time she's finished cumming 
and doesn't notice as Mutsumi retrieves something from the toy chest.

Kneeling opposite Momoko, Mutsumi hands the blonde a pair of rubber 
gloves, explaining, "I think we should massage our seed into Ai-chan, 
but we might go crazy from the aphrodisiac if we do it bare handed."

Shaking her head to clear it of her post-orgasmic fog, Momoko puts on 
the gloves as she declares, "I like that idea!"

Donning her own gloves, Mutsumi uses the remote to shrink Aiko's 
futahood to a mere half-inch diameter and 4-inch length, smaller than 
even the smallest dildo in the case before placing her gloved hands into 
the pearly white mess covering Aiko's chest and tummy.

Following the wrestler's lead, Momoko places her own gloved hands upon 
Aiko, and as the pair start to massage the runner's sleek pecs and abs, 
using their seed as improvised massage oil, the blunette starts moaning 
loudly, and it's quite clear that the blue apprentice would be writhing 
in pleasure if her bindings gave her enough slack to do so.

Once they've thoroughly spread their seed all over Aiko's torso, the 
pair decide to focus on the most sensitive spots, each girl using one 
hand to fondle the nearer of the blunette's budding breasts while Momoko 
uses her other hand to tease at Aiko's pussy and Mutsumi lightly strokes 
her fellow athlete's now rather pathetically small cock.

Sensing that their captive is nearing dual climax, or would be if not 
for the cock ring strangling the base of her shrunken futahood, the ring 
having tighten to match, both the blonde and the brunette remove their 
hands completely, causing the exhausted blunette to beg, "Please, please 
make me cum already."

"Hmmm..." hums the wrestler, thinking of what to do next before heading 
to the toy chest again, the magic providing the illusion that Mutsumi is 
in a dream producing a bottle of diuretic tablets and a liter bottle of 
Oy! Cola. Opening the soft drink, Mutsumi drops several of the tablets 
into the fizzy beverage and swirls the bottle gently to help them 
dissolve.

Kneeling by Aiko's head, the brunette fists her free hand in the bound 
girl's short blue locks before forcing the neck of the bottle into 
Aiko's mouth. With gravity making the cold liquid flow into her oral 
cavity, the track star has no choice but to swallow the soda to avoid 
drowning on it despite her piddle pot pounding in protest at further 
liquid consumption.

Once the bottle is empty, Mutsumi moves to between Aiko's legs, and 
using the remote to make sure Aiko's urinary sphincter is under the 
blunette's own control, the wrestler runs a finger teasingly along the 
underside of her fellow athlete's diminutive futahood as she says, 
"Ai-chan, I'm going to remove your cock ring. If you can hold your pee 
for five minutes without its assistance, I'll let you cum, but if you 
leak, the ring goes back on and I replace the pee you lost. Do you 
understand?"

Tensing up her every internal muscle in preparation for the challenge, 
Aiko nods her understanding as the wrestler pulls the shiny yellow loop 
of metal from the blunette's girlcock.

Though there is relief in no longer having the base of her member 
constricted, the pressure of pent-up pee pounding powerfully against the 
exit to Aiko's prodigiously protruding piddle pot seems to double as 
soon as the artificial barrier is removed, but even more desperate to 
cum than to pee, the frustrated futa fights ferociously to foil her 
tremendously taut tinkle tank's tactics to expel its contents.

It's the longest, most agonizing five minutes of the young witch 
apprentice's life, but eventually Mutsumi announces, "Congratulations!" 
as she flips Aiko's sphincter control to sealed. "Ai-chan managed to 
hold it in, and as promised, you get to cum as your reward."

Gripping the blunette's member, Mutsumi starts to gently bend it, trying 
to bring the tip down to Aiko's opening, but the short shaft isn't 
flexible enough. Using the remote, the wrestler lengthens her fellow 
athlete's futahood until it flexes enough to let the tip kiss Aiko's 
pussy.

Nearly cumming just from that brush of cock tip against nether lips, 
Aiko cries out, "What are ya doing, Mutsumi-chan?"

"I said that if you could hold it, I'd let you cum." replies the 
wresler, "What I didn't tell you is that I'd make you cum in your own 
pussy!" With that, Mutsumi pushes the penis length slider up by several 
inches, her fellow athlete's girlcock suddenly growing to force its tip 
past the blunette's lips and all the way to her cervix.

Aiko has no time to even protest as the sudden sensation of being buried 
cervix deep in her own pussy after being overdosed with aphrodisiac, 
teased, and denied is enough to trigger both of her orgasms, her entire 
body trembling as much as the weights holding her in place will allow as 
the blunette's futahood erupts with great gooey gobs of futa seed right 
against the entrance to her womb even as her pussy convulses in an 
effort to milk her own cock dry and suck all of her seed into her own 
womb.

As Mutsumi watches the blunette shooting herself full of semen and 
looking completely enraptured by the experience, she can't help stroking 
her own member, and glancing over to Momoko sees the blonde doing the 
same.

Deciding that Aiko came way too quickly, Mutsumi gets a devilish smile 
as she reaches for the arch of girlcock connecting the root of Aiko's 
futahood to the blunette's pussy. As the wrestler starts to manipulate 
that loop of sensitive futa flesh, making the rest of Aiko's member 
slide in and out of her pussy, the track star starts moaning, this time 
in euphoria rather than sexual frustration, the blunette too lost in her 
own pleasure to worry about the possibility that her own swimmers will 
beat Mutsumi's to her egg.

Mutsumi continues giving Aiko some much overdue stimulation until the 
blunette announces, "Mutsumi-chan, I'm gonna cum again!"

Deciding there would be no further humiliation value in making her 
fellow athlete give herself a second creampie, Mutsumi suddenly yanks 
Aiko's futahood, now unusually long for how slender it is, and slides 
the cock ring along its length, leaving the blue apprentice hanging just 
shy of another climax.

Ignoring the blunette's muffled curses at being once more constrained by 
the magical artifact, Mutsumi can't help wondering how it would feel to 
fuck herself. Gripping her futahood with both hands, the wrestler starts 
to gently bend her own member, curving it towards her own dripping wet 
pussy. She needs to give herself some extra length to manage without 
bending her girlcock to the point of pain, but it isn't long before the 
brunette can feel her tip pressed snuggly against her cervix. Adjusting 
her girth to the thickest setting her twat can handle, Mutsumi simply 
savors the sensations of being buried in a tight twatty while being 
simultaneously stuffed with a colossal cock, the naughty thrill of it 
all only made all the greater by it being her own pussy that she's 
buried in and her own girlcock that she's stuffed with.

Once used to the sensation of penetrating her own pussy and being 
penetrated by her own penis, Mutsumi reaches down to stroke the loop of 
futahoodprotruding from her crotch, but her body soon demands more and 
she starts using the leverage provided to start literally fucking 
herself much as she made Aiko fuck herself mere minutes earlier.

Before too long, Mutsumi can feel the now familiar sensation of 
impending male orgasm as her throbbing tool twitches terribly, 
threatening total insemination of her tight twatty.

Mutsumi considers pulling out of herself to shoot off in either Momoko 
or Aiko, but fucking her own pussy with her own girlcock feels way too 
good for the wrestler to muster the willpower to pull fully from her 
depths as she withdraws, instead ramming her futahood full force to her 
cervix every time. Eventually, the brunette pushes herself past the 
point of no return, her prick pressed firmly against her cervix as she 
pumps herself full of potent futa seed, flooding her preteen womb to 
capacity and then some, her trim tummy starting to protrude a bit above 
the bulge of her bladder, reminding the brunette of her full bladder as 
its compressed by her now full womb.

Once her climax has subsided, Mutsumi finally manages to pull her 
futahood fully from her feminninity and turns her attention once more to 
the blonde and blunette. Stifling a yawn and doing her best to ignore 
the fatigue she's feeling, Mutsumi heads over to Aiko's bound form, her 
futa seed running down the insides of her thighs, and with some 
difficulty, rearranges the weights so the blue apprentice's ankles are 
next to her head and her rear is slightly elevated.

Squating over Aiko's crotch, Mutsumi lines up the blunette's slender 
futahood with her pussy as she lines up her own member with the 
blunette's, letting out another moan as the two futa mutually penetrate 
each other. Starting to bounce, the wrestler increases both their 
girths, Aiko's to match what the brunette used to fuck herself, and her 
own to what she first used to fuck the blunette.

Too lost in pleasure and exhaustion-induced dilirium to process Aiko's 
protests, Mutsumi spreads the blunette's ass cheeks and invites, "Come 
on, Momo-chan, give Ai-chan's butt a good battering."

Momoko complies, and as the two start double teaming the bound girl in 
earnest, blonde and brunette start to make out.

Having worked herself up quite a bit while watching Mutsumi first make 
Aiko fuck herself and then as the brunette did the same to herself, it 
isn't long before Momoko breaks the kiss to announce, "[I'm close to 
shooting Ai-chan's ass full of jizz!]"

Even on the verge of collapsing from exhaustion, Mutsumi can make a good 
guess as to what Momoko's foreign words mean, and manages to tune the 
remote to the blonde as she slams the penis length slider to zero. With 
her diminished stamina, the sight of a sexually frustrated Momoko 
whimpering at the sudden loss of stimulation and grabbing at her crotch 
as her futahood reverts to a clitoris is enough to send the brunette 
over the edge one last time, her girlcock twitching as it delivers a 
comparably feeble load to Aiko's girlhood and massages the blunette's 
futahood in a vain attempt to milk cum from the ringed cock.

Her exhaustion finally catching up to her, Mutsumi passes out, and 
despite still being rather upset at having her transformation reverted 
just shy of climax, Momoko manages to catch the wrestler before she can 
fall.
