****** Growing Girls ******
by fuckingcommissions
Summary
     The girls grow more curious, and decide to enlist the help of Spike
     to satisfy that curiosity.
***** Chapter 1 *****
The girls have wanted to try some more grown up games at their sleepovers for
some time now, and so, at one of their sleepovers, they decide ahead of time
that they will bring something to aid in that. Each of the girls is tasked with
finding something to bring for their naughty night in, and once they’ve all
arrived and know that they are properly alone, they bring out what they’re
contributing to the night.
Diamond Tiara shows off the massage oil that she stole from her parents, while
Applebloom brings out some particularly phallic vegetables that she found in
the harvest from her family’s vegetable patch. Sweetie seems to have won the
night at first, with the platinum dildo that she stole from Rarity, but then
Scootaloo dumps out a collection of hentai and doujinish that Rainbow Dash
seemed all too eager to lend her, saying that she was “finally growing up.”
After they finish marveling over what the other girls managed to get, they
decide to have some soda before they start getting into them. They want to get
their bladders filling, and, once they’ve finished their soda, they strip down
to their cutie mark print panties, all excited to get down to business.
The most pressing matter, they all decide, is to look through the books that
Scootaloo has brought, and as they look over them together, they begin to
discover subject matter that they never considered. It is some of their early
exposure to kinks, and though most things that they see are completely new to
them, there are things that each of them find interesting.
Diamond Tiara takes a particular interest in seeing people tied up, and takes
an even greater interest when it’s a girl doing it, and when she uses a riding
crop for “disciplinary purposes”, though she balks the first time she sees a
rimjob drawn out. Sweetie tends to gravitate more towards girls being babied by
older men and is absolutely terrified of the concept of docking (needless to
say, both she and Diamond Tiara are not big fans of anything involving two
men).
Applebloom, on the other hand, shows a lot of interest in those sorts of
things, and stares in fascination at anything where she sees men going at it.
Her own squicks come from heavy sadomasochism, which Scootaloo doesn’t seem to
mind at all. However, Scootaloo prefers anything with two girls, particularly
anything that reminds her of Rainbow Dash. Her own disgust comes from Rainbow
Dash’s collection of porn involving fisting, both anal and vaginal.
Needless to say, all four of them find their opinion of Rainbow Dash greatly
changed upon discovering what a wide range of interests she has, and her
eagerness to collect this much physical material for all of it.
All the while, their bladders continue to fill, and while they look at
everything- and all are pleased to discover some material that has to do with
pee desperation, and even watersports- they grow increasingly more horny as
well. Once they are all desperate to both pee and cum, they decide to pair off,
and really get down to business.
Applebloom takes Sweetie with her, and begins trying to convince her to let her
use a carrot, something that Sweetie is not too sure about. “I don’t know,
won’t that hurt?”
“I’ll be gentle!” Applebloom replies. “Besides, a carrot is pretty small, and
you saw some of the things they put in them in those books!” She continues to
sweet talk Sweetie, until she gets the other girl to agree to it, and lay back
for her. Once she has her panties out of the way, Applebloom gently works the
tip of the carrot inside of her, prodding her insides while avoiding piercing
her hymen.
It isn’t long before Sweetie is squirming and moaning underneath Applebloom,
coming to love the feeling of having something inside of her. While this is
going on, Diamond Tiara takes Scootaloo for herself, asking her if she’d like
to try a massage.
Scootaloo is enthusiastic, lying down on her stomach while Diamond Tiara
straddles her rear, getting her slathered in the special massage oil. Her small
wings flutter in excitement as Diamond Tiara begins to work at the tension in
her shoulders and back, and it melts away under her touch.
She scoots back further and further as she massages her, until she’s on her
legs, giving Scootaloo a very pleasant surprise when she yanks down her
panties, prodding at her anus with one of her slick fingers for a moment before
reaching down to try fingering her pussy.
Scootaloo cries out in delight as Diamond Tiara begins to work a finger inside
of her, her moans matching Sweetie’s while Applebloom fucks her with a carrot.
She grows closer to her orgasm, and when she finally reaches that point, her
weaker bladder gives in as well. While she moans out in ecstasy, she wets
herself as well.
Just when Scootaloo is near orgasm, Diamond Tiara halts her internal massage,
and uses her magic to flip the other girl over, to massage her front. Scootaloo
continues to hope that she will resume fingering her, but when she is done, she
pulls away and leaves Scootaloo desperate and needy.
Deciding that she can’t take anymore, she jumps up to grab a cucumber that she
fits inside of her, before tackling Diamond Tiara to fuck her with the other
end. Diamond Tiara is quite delighted that her plan to make Scootaloo lose all
self-control worked, and it isn’t long into her thrusts before the two of them
reach a simultaneous orgasm, their bladders giving out at the same time.
Applebloom is the last one standing, and relaxes, deciding to deliberately
empty her bladder to make Sweetie feel better about how quickly she wet
herself, and is able to finish herself off in the midst of her relief. Now that
all four girls have come and emptied their full bladders, they decide to relax
for a moment, before they start worrying about cleanup.
And it is while they are relaxing in their bliss and relief that one of them
voices the question on all of their mind. Diamond Tiara speaks up to say, “I
wonder what it would be like to actually do it with a boy.”
This sparks a conversation that makes their sleepover get a lot more
interesting.
***** Chapter 2 *****
As soon as Diamond Tiara actually asks the big question, the girls begin
discussing the topic at hand, and it isn’t long before they begin discussing
possible boys to try things with. All of them are so curious about it now that
they wish that they could try it out, and that is when they begin to talk about
the boys in their class that they can invite to give them their first taste.
As they work through their classmates, they end up vetoing every boy they come
across, with all of them expressing disgust when both Snips and Snails come up.
Of course, with their classmates out of the question, they start to talk about
the boys and men they know from around Ponyville.
“What about…?”
“Too boring.”
“How about…?”
“I think he’s got a girlfriend.”
“We could always…”
“He’s so weird looking, though!”
“What about Big Macintosh?”
“Um, you do know that’s my brother, right?!” Applebloom protests.
“Oh, yeah,” Sweetie says with a blush. “I forgot.”
They work through several men and several boys, until finally, they all decide
on someone that they think would be suitable. He isn’t too far out of their age
group, and it isn’t like he’s getting any action, they’re pretty sure, and so,
they all agree that Spike would be the perfect boy to offer their virginities
to. What started as a hypothetical discussion has become a plan, and they start
to plot about it, deciding that, since Hearts and Hooves Day is coming up, the
four of them will use that as an opportunity to seduce Spike, and get what they
want from him.
~X~
On the day of, they plan to wear the sexiest outfits that each of them own.
Scootaloo wears a form fitting tank top and biker shorts, while Applebloom
wears a knotted blouse and jean shorts, and both Diamond Tiara and Sweetie
Belle wear matching school uniforms. They invite Spike to come visit their
treehouse, and though he claims at first that he’s going to be busy helping
Twilight Sparkle all day, it takes surprisingly little convincing to get him to
decide to ditch his work for a little bit.
All four like to think that he’s having a hard time looking at anything other
than their bodies in the outfits. Each of them does what they can to emphasize
what curves they have, to try and seduce him the best they can. It may be their
first time doing something like this, but they know plenty about exciting one
another.
Whatever the case, once they’re ready for him to come upstairs, they call for
him, and he enters to see Scootaloo having changed into a different tank top
and pair of bike shorts, but these are so tight and skimpy that it’s closer to
a sports bra and panties, leaving her girlhood and nipples somewhat visible
through the tight fabric. She is flanked on either side by the unicorns in
matching nighties of white silk.
Spike, unsure of what he’s just walked into, both grows nervous and aroused,
and then Applebloom sneaks up behind him to give him a hug. He turns just
enough to see her in a flannel nightgown, and then the other girls begin to
close in on them. Even the shortest of them is still taller than him, and he
has absolutely no hope of fighting them all off like this, and, what’s more,
he’s not sure that he even wants to.
While he’s trapped in their group embrace, Sweetie presses her lips to his, and
he is so surprised by the kiss that he can’t close his mouth before she presses
a gem into his mouth. He wants to resist this, and it has a strange flavor, but
it is so irresistibly delicious to him that, as Sweetie pulls back from the
kiss, he crunches and swallows the gem, still not sure what it is that she’s
fed him.
“Wh-what was that?” he stammers.
“It was just a little something to make sure that you had the energy to satisfy
all four girls!” Sweetie replies with an innocent grin that he knows is
anything but innocent. And then she and her friends begin working to get him
stripped out of his clothes and down on the floor.
Once his cock is on display for them, all four are impressed by his size,
especially given how it relates to the rest of him, and, after marveling for a
moment, they put the next phase of their plan into action. Scootaloo straddles
his face, Applebloom sits between his legs, and Diamond Tiara and Sweetie kneel
to either side of him. He asks them what they’re doing, and Diamond Tiara says,
“Just lay back and let us play with our new toy!”
Scootaloo leans her face down to suck at his tip then, and he moans out in
sudden surprise.
He doesn’t even have a chance to collect his thoughts after that, before
Applebloom leans forward to suck at his balls, and both of the unicorns lick at
the sides of his shaft. Between all four mouths, he is left completely
helpless, and, as he loses himself to pleasure, he gives into the instinct
telling him to reciprocate this pleasure. He pulls down Scootaloo’s shorts so
that he can bury his tongue in his girlhood, his lack of experience not
hindering him in the slightest.
While he puts his tongue to good use, the four girls put their mouths to
equally good use, all working to get him off, just to see if they can.
Scootaloo finds that she has a hard time focusing with his tongue buried inside
of her, and she feels herself growing close all too soon. Fortunately for her,
Spike is nearing his limits as well, and it is around the time she sprays his
mouth with her juices, crying out in ecstasy, that he gives in, moaning into
her as his seed shoots into her mouth.
It takes a moment for the two of them to catch their breath, but Scootaloo
makes sure not to swallow until she has had the chance to kiss each of the
girls and give them a taste of Spike’s seed. Each girl gets their turn kissing
Scootaloo while Spike tries to catch his breath.
Once Scootaloo can swallow what is left, she says, “Man, your tongue is wicked!
Nice one!” and he blushes at her words, glad that he was able to do something
for her when he was utterly clueless as to what was happening.
Of course, now comes the question of who actually loses their virginity first,
and considering all are intimidated by his size, they all hang back, wondering
if they will be brave enough to step forward.
***** Chapter 3 *****
Eventually, it is Scootaloo who works up the courage first, knowing that
somebody has to do it first and not wanting to be branded a coward in the face
of something like this. She climbs on top of Spike, straddling him and
squatting over his erection, taking a deep breath before she impales herself.
She does not take it nearly slowly enough, and it is painful to have him
stretch her so suddenly, and she has to take a moment to try to recover from
the pain, and adjust to the feeling. She hisses and holds her breath, until she
is finally able to get used to having him inside of her.
Once she is used to it, however, she begins to move, and once she has begun to
move, she finds that she likes that, and it isn’t long before she’s bouncing on
top of him, and the other girls take up positions around him as well, with
Sweetie getting a turn on his mouth, and the other two watching as he pleasures
them both.
Soon enough, Scootaloo reaches her first climax with a boy, and the feeling of
her convulsing around him is enough to send Spike into an orgasm, flooding her
womb with his seed. That is when Sweetie reaches her climax as well, and her
weak bladder gives out, something that Spike does not seem to mind at all,
considering the eager way in which he laps it up.
Diamond Tiara and Applebloom don’t give the two much chance to recover before
yanking them out of the way, both wanting a turn after being made to wait so
much. Diamond Tiara takes her place on Spike’s mouth while Applebloom is ready
to give up her virginity now, getting on top of his cock, and bracing herself
before she begins to sink down onto it.
Applebloom only has slightly more trouble fitting him inside of her, but she
takes it slower and is able to adjust more easily as a result, clasping hands
with Diamond Tiara as she takes him inside of her. The girls lean forward,
joining in a kiss as Applebloom adjusts to Spike’s cock and begins to ride him,
and as Diamond Tiara begins to relax into Spike’s treatment, his tongue working
inside of her and pleasure her just as it did both Scootaloo and Sweetie
already.
The girls squeeze hands as they both experience different sorts of pleasure,
going deeper into the kiss as their passion grows. Spike is honestly blown away
watching the display of affection between the two girls, and this increases his
own passion as he drives up into Applebloom, faster and faster, wanting to get
off now more than ever before. He moans into Diamond Tiara as he does, and she
gives Applebloom’s hands a tight squeeze, knowing that she is so close now that
it won’t be long for her.
Sensing this, Applebloom squeezes back, letting her friend know that it is all
the same for her, and the two of them know that Spike must be close. The girls
reach that point at the same time, moaning into one another’s mouths as they
come, and once again, the feeling of having a girl’s pussy tighten and convulse
around him leads to Spike coming deep inside of her, filling her just as he did
Scootaloo.
They take a moment to recover before the two girls switch places, and
Applebloom happily settles down on Spike’s face, while Diamond Tiara finds
herself growing nervous. She slowly starts to sink down onto his cock, but as
soon as she begins to feel pain, she stops short, wincing and fighting back
nervous tears.
“What’s wrong?” Applebloom asks. “You’ve barely even started.”
“Hurts,” she mumbles. “I want to stop…”
“It’ll get better! Just keep it up!” her friend encourages, and Scootaloo
echoes the sentiment, telling her that she has nothing to worry about. Since
Diamond Tiara doesn’t want to risk looking lame in front of her friends, she
grits her teeth and presses on, continuing to sink down and take more and more
of him, fighting through the pain until she has him completely inside of her,
relaxing until she is used to the feeling of him filling her up.
Fortunately for her, it isn’t long before the pleasure overrides the pain, and
she is able to see exactly what it is that left both Scootaloo and Applebloom
breathless. She and Applebloom take each other’s hands again, as Diamond Tiara
begins to ride him, bouncing up and down as the pain completely subsides. Spike
puts his tongue to good use inside Applebloom while he fucks Diamond Tiara, and
doesn’t feel any of the exhaustion that he should have after been used so much.
It seems that the gem stone they fed him is doing exactly what it’s supposed
to.
When the three of them come together again, they have a bit more time to
recover than the other two girls did, because there is only one girl left who
hasn’t had a turn riding Spike’s spike, and she is in no hurry. Even after
watching all of her friends do it without much problem, she knows that it will
be different for her. Her pussy is the smallest of her friends, and her hymen
is the only one that’s survived all of their experiments, and she outright
refuses once Applebloom notices that she’s hanging back.
As Diamond Tiara climbs off, she insists, “It feels great, you’ll be fine!”
“Yeah, nothing to worry about!”
“You can do it, Sweetie!”
“No way, he’ll rip me apart!” she protests, until Applebloom and Scootaloo grab
her, and she thrashes as they lift her above his reaction, and force her down,
the weight of it forcing his cock balls deep inside of her.
“Ow! Frick!” Sweetie shouts, the childish profanity surprising her friends.
“Dang it, frick, that really freaking hurts!” Even as the pain begins to
subside, a rather long process, she refuses to move out of fear that she will
make it worse.
So her friends begin moving her up and down and she wails, “No, you’ll rip my
insides out!” They don’t listen to her, and keep it up, moving her up and down
until there is no pain left, and she is made to enjoy it. She calms down at
that point, giving way to pleasure, and once Spike reaches his orgasm and fills
her with his seed, she is sent into the strongest orgasm of her life.
Still, she doubts she will be forgiving her friends for forcing her into this
any time soon.
When Spike finally recovers from being used, he exclaims, “That was so amazing!
Really, you guys surprised me, but I’d love to do that again!”
The four girls surround him, all saying that they’d be delighted to, and he
smiles. However, his smile is soon wiped away by what they say next.
“Anyway, we’ve got a question.”
“Something we’re all dying to know!”
“So you’d better answer!”
“Which of our pussies did you like best?”
He gulps.
