Younger Twins by ImoutoCommissions

Chapter 1

At the age of ten, Fuu and Ran go on their first Valentine date, and the 
experience is not at all dampered by the fact that their parents have to 
chaperone them. To them, it is more like going on a double date, and 
both are happy to have their parents there with them. It is a nice 
family affair, though they have to pretend that it is just that, and 
nothing more, so that nobody catches on that the younger twins are 
following in their parents' footsteps.

Whatever the case, all four of them have Fun together on their double 
date, and when they get home, Fuu and Ran go to shower together. Neither 
one of them are sure which came up with the idea to do so first, or if 
it occurred to them at the same time, rather than being influenced by 
their twin, but while Ran is scrubbing her brother's back, she orders 
him to turn around and he does so.

As she begins to wash him from the front, she spends less time on his 
chest or stomach, and more time going lower, and focusing on certain 
regions of his body for longer than is necessary. Finally, she kneels 
down before him, using one of her soapy hands to stroke up and down his 
now-erect member, and using the other to fondle his balls, leaving him 
panting and squirming while she pleasures him.

When she senses through their bond that he's growing close, she stops 
short, standing up and turning her back to him. From the way she acts, 
one might think she's forgotten that she's left him hanging, and says, 
"It's time for you to wash my back now." While she speaks, she gives a 
seductive sway of her hips.

His near-protests fall short, and he decides to take this opportunity to 
give her a massage, rubbing her shoulders more than scrubbing them, and 
digging his fingers into her flesh as he works his hands down, until 
she's moaning from it. By the time he reaches her cute butt, he slows 
down enough to simply grope it, something that she does not protest at 
all. He takes his time admiring his twin sister's body, but when he 
finishes, he does not ask her to turn around.

Instead, he pulls her tight to his chest, his erection sliding between 
her thighs and rubbing against her as he reaches around to wash her 
front. While he washes her flat chest, he wonders when she will start 
budding there, but the thought occurs to her as well, and it is shared 
across their link, making it impossible for them to determine where the 
thought originally came from.

Either way, he washes her there, rubbing his hands over her tiny nipples 
and wondering about when they might begin to grow, until he works his 
hands lower. All the while, he thrusts forward and back, his small cock 
rubbing between her thighs and stimulating her, making sure to graze her 
clit as much as possible. He teases Ran as she teased him, until she is 
squirming and needy, and then, he hears her voice across their link, 
knowing this time exactly where the thought came from.

"Stick it in me!" she begs him telepathically, desperation clear even in 
her internal voice. "I know you want to do it as much as I want it, I 
can feel it!"

Though she's right, he still denies her request, and instead 
telepathically replies, "Not until you say it out loud."

"Please, stick it in me," she says aloud.

"Louder," he replies, internally.

"Please, stick it in me!"

"Louder, sister."

"Please! Stick it in me! I want you to fuck me, brother!" she screams at 
the top of her lungs, and he finally decides to give in to her demands. 
After all, she's right about him wanting it as badly as her, considering 
how much she teased him before.

And so, he pushes inside of her opening without hesitation, still 
holding her close as he does so, and she cries out in ecstasy as he 
buries himself inside of her. He moans as well, the two of them making 
plenty of verbal noise to show their enthusiasm as they make love, and 
though he wants to mentally tease her more, he can barely make sense of 
his own thoughts, as theirs mingle, becoming more and more incoherent 
due to their shared pleasure.

"More!" she says, because she can't figure out how to think right now, 
can't think to do anything but beg him verbally, even knowing that he 
knows exactly what she's going to say before she says it. He wants more 
just as much as she does, with their shared thoughts, but still she 
cries out for it, because she can't think straight in this moment.

The more she cries out for him, the harder he drives into her, matching 
her energy and her desires perfectly, their link only serving to 
heighten their experience, just as their parents always told them it 
would. They've learned a lot from their parents, and really are taking 
after them quite a bit.

Both are pushed closer by the other, until Ran begins to tremble around 
him, and Fuu begins to twitch inside of her with his orgasm, the two of 
them coming together and crying out in perfect unison, barely even 
sounding like separate people as they do. Because of their link, their 
pleasure is shared and therefore magnified, and they have to help 
support one another as they ride out their orgasms, and then try to 
recover from it in the afterglow. Fuu helps Ran to not collapse, while 
leaning on her at the same time, and the two of them pant to catch their 
breath.

Once they have both recovered, the two of them rinse off together, 
making sure to get properly clean this time. They get out of the shower 
after this, and reach for their matching towels, both blue like their 
family's signature garb. They help each other wrap the towel around 
themselves, so that they are both covered from under their arms to below 
the knees.

Fuu lifts his sister into his arms, using his telekinesis to help him 
with carrying her. Though she is not particularly heavy, he is also not 
particularly strong, and he needs that assistance to be able to carry 
her bridal style, which he does all the way to their bedroom, laying her 
down on the bed and letting his towel pool around his ankles before 
climbing on top of her, still longing for more.

Chapter 2

Fuu climbs on top of his twin sister and unwraps the towel around her, 
exposing her body to him once more. He presses his lips to hers, and she 
returns the kiss with enthusiasm, moaning and opening her mouth so that 
he can work his tongue in, moaning into her mouth as well. Just as 
anything else they do, their kisses are perfectly in sync, as they can 
match one another's movements and needs easily.

Their passionate kiss goes on for some time before he breaks it and 
begins to trail kisses down her neck, and Ran squirms under him as he 
does so. His kisses go lower than that even, and by the time he reaches 
one of her nipples, she can hardly breathe from the teasing pleasure.

He kisses lower and lower, taking his time kissing down her stomach, 
dragging it out to tease her longer, and she mentally scolds him, 
knowing that this is what he's trying to do. He doesn't bother replying, 
and she knows that there is nothing she can do to stop him.

While he takes his time as much as he can, eventually, he reaches the 
apex of her thighs, nuzzling his face between her legs. He begins to eat 
her out slowly, pressing his tongue inside of her and reaching through 
their link to experience the pleasure that she does when he does this. 
In that way, it makes it equally as torturous for him when he teases 
her, but it also helps him understand everything he does to her, and 
what else he can do, how far he is able to push her.

He buries his tongue deeper within her, delving into every inch of her 
that he can reach, taking his time as he does, and as he feels her 
pleasure increase, so does his own desire to speed things up and get to 
fucking her already. But he holds out, continuing to use his tongue 
inside of her, to bring her closer and closer, paying close attention so 
that he does not push her over the edge just yet.

She tries to scold him again, and beg him for more, but he draws it out 
and ignores her, until he can tell that she is right on the edge, that 
any further stimulation will leave her pulsing with her orgasm. That is 
when he stops completely, not allowing her to come just yet.

Ran whines as he pulls his mouth back, and begins kissing back up, onto 
her stomach again, and kissing along her other side. He teases her all 
the way up her body again, leaving her squirming again, and when he 
reaches her other nipple, she cries out in need just like before. 
Finally, he makes the long trip up her neck, until he captures her lips 
in a kiss, this one even more passionate than the last.

While Ran hungrily returns the kiss and squirms desperately beneath him, 
he finally presses his cock against her, and then inside of her, sliding 
all the way into her to satisfy her craving. Ran wraps her legs around 
him, as if to keep him trapped there so that he cannot pull out and try 
to tease her again, and they both wrap their arms around one another, 
holding tight to each other as they begin to work their hips in tandem, 
finding the perfect rhythm with complete ease due to their psychic link, 
reading each other and working together to fulfill a need that they've 
helped build in one another.

It doesn't take long for Ran to grow close again, reaching back to the 
point Fuu left her at, and he is brought there with her. When they are 
both on the edge together, there is nothing they can do to prolong 
things, and the two of them cry out together as they reach another 
simultaneous orgasm. However, while they're lost in familiar convulsions 
and twitches, both sense something different, and while they are too 
overcome with pleasure to determine what it is at first, they both know 
that something is off. It takes them time to come to their senses, but 
as they think about it together, they're able to reach the same 
conclusion, a bit faster than they might have alone. The only other time 
they've experienced anything like this is when their father came inside 
of Ran before, and, with that in mind, they soon determine that Fuu must 
have just experienced his first ejaculation.

They know that they need to tell their parents, but they are tired now 
and don't want to leave their intimate embrace. What's more, they're 
sure that their parents are likely locked in a similar embrace, and so 
they decide to wait until morning to tell their parents about their new 
discovery.

~X~

After informing their parents of the news, Liza takes Ran with her to 
the gynecologist, claiming that she already had need for an appointment, 
but can also take Ran to get her on birth control. However, it is during 
this appointment that they find out that it is already too late for 
that; Ran is already pregnant.

"You won't be doing it alone," Liza tells her daughter. "I'm pregnant 
again as well. Now, we just need to find the best way to tell our 
brothers, don't we?"

They discuss how best to do so, and when they're alone with the boys, 
they first address their brothers, with Liza telling Tate that he will 
be a father again, and Ran telling Fuu that he will be a big brother 
again, both guiding their hands to rest on Liza's stomach.

It is while the boys are expressing their excitement that Liza 
interrupts them to say, "And you will also be a grandfather."

"And you will be a father," Ran adds, and they guide their hands to her 
stomach this time.

It takes a moment for the news to sink in, and then...both boys fall to 
the ground, fainting away in their surprise. Liza and Ran both giggle at 
their dramatic reactions, and Liza asks, "Do you think we can-"

"-revive them with sex?" Ran finishes, neither of them needing a psychic 
link to know what the other is thinking. The two begin to giggle even 
harder.
