****** The Art of Pleasure ******
by FandomFreak1980
Summary
     As the Potter twins approach their thirteenth birthday in a highly
     sexualized Magical World, they prepare to learn all that they can
     about the art of pleasuring themselves and others.
Notes
     Just about the only OFC I'll use will be Harry's twin. There may be
     occasional others, but I'll try to mainly stick to established
     characters. The Harry/Harry tag is because except for obvious gender-
     specific differences (plus one famous scar), they look exactly alike.
     Updates will probably be sporadic. Sorry, that's just my personality.
     I will update characters, relationships, and tags as necessary.
     This first chapter is a prologue designed to establish the rules of
     my AU. Content will be explicit beginning in chapter two.
     Thank you, and enjoy!
***** Prologue *****
Jasmine Potter was excited. She and her brother had their thirteenth birthday
in a week, and they had received their Ministry-Approved Beginner's Pleasure
Boxes by owl that very morning. They included the standard range of toys
designed to help the young witches and wizards discover the kinks and fetishes
that excited them along with a supply of lubricant and whatever other potions
they had requested from the list. Every witch's box also contained a special
potion that painlessly removed the hymen so that the pain of tearing it
wouldn't detract from the pleasure of her first time. Jasmine and Harry had
also requested a potion to remove all of their body hair. They currently
enjoyed the looks of their prepubescent bodies and wanted to maintain as much
of the illusion as possible.
Jasmine sat on their shared bed (because the Dursleys couldn't be bothered to
purchase an extra one) with her box in her hands and fondly remembered the day
she had first learned of them. It had been a surprise to say the least. On the
first day of Hogwarts, upon entering the common room for the first time, the
prefects had separated the girls from the boys and taken them to the respective
seventh-year dorms for their first lesson in Magical Sexual Education. The talk
was mainly for the muggleborn and muggle-raised students; most of those who
were raised in the magical world were already privy to the information covered.
They were told that magical beings as a whole (humans and creatures alike) are
very sexual. Having sex of any kind regularly helps to grow, strengthen, and
stabilize their magical cores. They were also told that all magical beings go
through puberty the night before their thirteenth birthdays, and they would
begin feeling the need to act on sexual urges at that time if they hadn't
already. It was said that, although it was a rare occurrence, more potentially
powerful witches and wizards had been known to have erotic dreams and urges as
much as several months in advance of their birthdays. However, they were not
allowed to indulge in anything more than self-gratification until they were of
consenting age, which had necessarily been designated thirteen since it was
needed afterwards to grow their cores.
One of the most surprising things learned that night was that, not only was sex
between adults and teenagers legal, it was also expected! Even between family
members! (Especially between family members!) They learned that after that
special birthday, the adult with the closest bond to the new teen (usually a
parent or other adult family member) would feel a magical pull that would take
them to wherever the teen happened to be. It would be that adult's
responsibility to introduce the teen to new forms of pleasure, whether they
were taking his or her virginity or not (the teen may have already been with
peers if the adult couldn't get there right away). After that, the teen could
be with whomever he or she wanted as long as they were of age and everything
was consensual. Pregnancy would be a nonissue due to a flavorless contraceptive
potion in all drinks served at the school and a  take-home supply available for
summer months.
While all of that was interesting and would be all kinds of fun when she was
old enough, what had surprised Jasmine the most (somehow even more than the
thing about adults or incest) was that over the following two years, they would
be getting lessons on how to perform. Some of these lessons would be joint
lessons with the boys, and some would be strictly girl-on-girl (it was at this
point they learned that easily ninety-eight percent of the magical community is
bisexual). These lessons would consist of descriptions of different acts and
situations followed by demonstrations. As first-years, they would be required
to watch without participating, but the second-years would be allowed to
practice if they had already had their birthday. Older years could also help
with demonstrations but were not required to attend.
Jasmine hadn't thought it was fair watching as more and more of her friends
were allowed to participate and knowing that she would have to wait half of the
summer before she could even start to join in. She knew Harry was getting
impatient, too, but she also knew that was because he had begun having wet
dreams even before March in their second year. Oh, how she had wished she could
help him out, but she knew she couldn't. She had lost count of the number of
times she had woken up to hear Harry moaning in his sleep with an erection
causing their blanket to tent over his groin. Jasmine had had several erotic
dreams herself after they had come home for the summer. She had been waiting,
not quite patiently, for the day she could relieve that ache on Harry's pole
instead of her own fingers.
Knowing she only had a week left, Jasmine sat on the single twin-sized bed in
the room she and Harry had shared since they outgrew the cupboard, imagining
what she would do when that week was up, and waited for Harry to finish his
chores so they could take their potions together.
***** Birthday Presents *****
Chapter Summary
     The morning of the twins' birthday.
Chapter Notes
See the end of the chapter for notes
Jasmine woke up just as the sun was rising. She liked waking up early because
the family always slept in, and they had at least an hour of quiet before
someone came by for them. She smiled and stretched. As she did, she felt
Harry's very obvious hard on prodding her backside. Apparently, he was having
a really good dream. She pressed back against him and grinned to herself as he
moaned in his sleep. 
Jasmine bit her bottom lip between her teeth for a minute before deciding to
give Harry a very special birthday present to wake him up. She turned over
carefully so as not to jostle the bed and slid down along Harry's body, taking
the blanket with her. Between her silky new pajamas and Harry's silky new sleep
pants, Jasmine could almost have cum from the sensation alone.
As Jasmine settled into position, she ran her hand lightly over Harry's torso,
feeling his Quidditch toned muscles, before lowering his pajamas to rest
beneath his manhood. She sat for just a moment to admire the tool jutting
proudly from Harry's smooth, hairless groin. They head glistened as it leaked
precum. Veins stood out in stark relief. She wrapped her fingers loosely around
him and ran her hand down the length to rest at the base of his shaft. She
marveled at the solid firmness surrounded by silky smooth skin. She was almost
hesitant to taste him. She had observed different techniques for two years and
had spent the last week practicing with one of her new toys, but she knew that
this would be different.
She leaned forward and tentatively swiped her tongue across the head. Pleased
with the taste, she took Harry slowly into her mouth, going a little lower with
each bob of her head until she had him completely encased and he was in her
throat. She set to work sliding her mouth up and down his length, taking him as
deep as she could, and occasionally sucking just the head, running her tongue
through the slit, or releasing his rod completely only to take a testicle into
her mouth.
Hmmm... I wonder if I can make him cum before he wakes up...
                                     *~*~*
Harry was having the most incredible dream. It started out with all of the
professional Quidditch players in Britain parading nude in front of him as he
stroked himself to hardness so that he could choose who he wanted for his
personal harem. He watched as beautifully sculpted male bodies and softly
curved female bodies walked slowly past him, displaying all they had to offer.
Just as he was preparing to fuck them into oblivion - or maybe to be fucked
into oblivion, he couldn't be sure - his dream changed. 
He was suddenly confronted with a pair of hands and a faceless mouth. The hands
came forward and stroked him lightly, the touch so soft, it almost wasn't
there. Just when he thought he couldn't stand it anymore, the mouth descended
and enveloped his prick. Harry was in heaven! His dreams had never been this
detailed before. As he was sucked into the wetness and warmth, he decided to
just see where it went. 
The mouth was talented, that was for sure, and the throat felt like it went on
forever! Those hands weren't to be forgotten, either. While one was at the base
of his dick, holding it in place for that magical mouth, the other was on his
balls, rubbing them, massaging them, and pulling them just a little, just how
he liked. 
He moaned loudly as he fisted his hands into the sheets on the bed his dream
world had supplied. He had never felt anything like this, and he knew he
wouldn't last long. Yes! Yes! Fuck, just like that! Oh, gods, don't stop! He
felt the tightening in his balls that always came right before...
                                     *~*~*
Harry woke up with a shout just in time to see his sister swallowing around his
cock as she took shot after shot of his cum down her throat. 
 "Jas, fuck!" Harry said as he pulled Jasmine up the bed to lay on top of him.
He wrapped one hand in the long, black braid she always slept in and pulled her
down for a forceful kiss. As his tongue plundered her mouth, his other hand
made its way beneath the ruffles at the hem of the pajama shorts that barely
covered her ass (Must remember to thank Hermione for sending us pajamas for our
birthday) and squeezed the firm globes, eliciting a needy moan from her.
Between that and the taste of his cum on her breath, he was back to full,
aching hardness.
Harry flipped them suddenly so that Jasmine was pinned to the bed beneath him
and groaned his need into her mouth as his fingers found her dripping wet slit.
She keened softly and writhed against him as he plunged his fingers into her
over and over again. Harry drew away from Jasmine and looked her in the eye as
he slowly and sensually sucked her juices from his fingers.
He kissed her again lightly, then gently nibbled down her neck, following each
tiny bite with a soothing kiss. He slid his hands under her pajama top, raising
it until she sat up just enough that he could lift it off and drop it to the
floor. He lowered his head to the barely budded peaks on her chest, sucking the
nipple in his mouth and laving it with his tongue before switching his
attention to the other side. He soon had both nipples as hard and firm as
little pebbles.
Harry met Jasmine's eyes with a smirk, lightly flicked his tongue once more
across each pebbled peak, then continued to lick, kiss, and nibble his way down
her stomach. He stopped momentarily when he reached the waistband of her
pajamas, nibbling at the skin there before hooking his fingers inside them and
pulling them down excruciatingly slowly, allowing his breath to ghost over each
patch of newly bared skin, but not touching her with his mouth. He finally
pulled the shorts free and lifted them to his nose to inhale their musky scent
before dropping them to join the top on the floor. He smoothed his hands slowly
back up her legs until, upon reaching her center, he lowered his mouth to suck
a mark into the tender inner flesh of first one thigh, then the  other, once
again only letting his breath play against the points in between without
actually touching her there. It proved to be a little too much for Jasmine.
 "Bloody FUCK, Harry! Would you just lick me already?" Jasmine exclaimed, her
chest heaving as if she'd run a marathon. "Please, Harry, I -I need..."
"What do you need, Jas?"
"Something. Anything. I just need... something...inside me! Please! Now!"
Harry looked up at her as she begged for what she wanted and smirked evilly
before plunging his tongue between her folds and lapping up the veritable lake
of slick juices he found there. The symphony of delicious sounds Jasmine was
making inspired him to see if he couldn't pull even more interesting noises
from her, and he sucked directly on her precious pearl. Harry was rewarded when
Jasmine arched her back off the bed and grabbed a pillow to muffle her shouts
so she didn't wake anyone.
Harry grinned, then began a relentless attack with his mouth, licking and
sucking her without letting up, while he fucked her with three of his fingers.
Thanks to the pillow, the sounds Jasmine was making were no longer coherent.
She was writhing under his ministrations. It didn't take long for her to come
undone, clenching around his fingers and drenching them in her cum.
Jasmine moved the pillow just in time to watch Harry lick his fingers clean. He
stood long enough to shed his pajamas, then crawled back onto the bed, walking
on his knees towards her while slowly stroking his painfully hard erection. He
guided himself to her still-dripping opening and, locking her legs behind him,
slid himself home with a single thrust.
Jasmine gasped loudly in ecstasy, trying and failing to keep her voice down,
while Harry sucked little bites along her collarbone. When she tilted her head
to allow him better access, he found her pulse point and sucked deeply with
each thrust. When she started whimpering and giving out those delectable little
"ohs" and "ahs" and "yes, Yes, YES!" that signalled Jasmine's orgasm was
building, Harry covered her mouth with his to swallow the sounds. 
To carry her to even greater heights and help her reach her peak more quickly,
he lifted one of Jasmine's legs to rest over his shoulder enabling him to drive
even deeper into her. As she screamed her pleasure into his mouth, he grunted
his pleasure into hers. Reaching her second climax of the morning, Jasmine
triggered Harry's as well.
 "Gods, fuck, YES!" Harry cried out before he could help himself as he emptied
himself into her. Jasmine quickly covered his mouth with her hand, and they
laid together quietly, not daring to breathe, as they listened to see if anyone
had woken up.
After they deemed it safe, they got up long enough to clean themselves up, then
decided to get back in bed for as much rest as they could get before morning
chores started.
Chapter End Notes
     Sorry for taking my time in this. I finished writing it a few days
     ago, but I've been trying to figure out a couple of bits I wanted to
     make changes to, and it fought with me.
     On the other hand, I know pretty much how the next two chapters will
     go (the twins will still be at their relatives' house for those), and
     I know what I want for the Hogwarts Express trip, but I want them to
     experience running away to Diagon Alley. I have a very basic setup in
     mind for the start of that trip, but I don't know what sexual
     experiences I want them to have, or with whom. Suggestions are
     welcome.
     Note: I will be introducing Sirius/Padfoot next chapter, and he will
     still be with them in Diagon Alley. Would you rather see something
     with a shopkeeper (and which one?) or maybe their first creature
     interaction (I have considered something with the goblins if I can
     get it figured out)?
