   Learning From the Gimp (Mf, 1st, bd, ds, nc, preg)

   Being a dominatrix is all about control.  Ava felt that control
temporarily slip from her grasp when her younger sister Noelle asked her to
teach her about sex.

   It was a surprise, as their Mom and Dad were conservative Christians,
and she thought Noelle would have been all goody-goody after being brought
up repressed like that.

   Their parents didn't talk to Ava anymore, not once they had found out
about her job, but she and Noelle had kept in touch through Facebook.

   Noelle didn't actually use the Internet to ask her sister to teach her
about sex.  She knew her parents went through her chat logs regularly.  She
had called her older sister from her best friend Megan's house one night
while she was staying over.

   "Please, Ava?  I'm 16 years old and I haven't even kissed a guy.  Mom
and Dad won't let me date while I'm living with them!  I'm so frustrated,
and when I finally start dating in college I'm not going to know anything!"
Noelle whined.

   Ava thought about her time in college.  That was exactly what had
happened to her.  The first time she'd ever seen a guy's cock she had
screamed and freaked out.  The guy had taken off, and her antics had become
public knowledge shortly thereafter, making her time at college both
embarrassing and depressing.  She wasn't going to let that happen to her
little sister as well.

   "Okay, sweetie.  Ask Mom and Dad to allow you to stay over at Megan's
this weekend, and then come to this address Saturday afternoon at 3." Ava
gave her sister her "office's" address, which was within walking distance
of Megan's place.

   "Really?!" Noelle squealed.  "That's awesome!  See you then...love you!"

   "Love you too," Ava said, already deep in thought as she hung up the
phone.

   ---

   Ava answered the door in her silk robe at 3 PM sharp on Saturday.  In
her doorway were Noelle...and Megan!

   "Noelle," Ava hissed at her sister as she glanced at her friend, "you
were supposed to come alone!"

   Noelle looked sheepish.  "You didn't say alone...you said stay over at
Megan's and come at 3, and we're here."

   In retrospect, Ava should have stopped everything right there, as she
did not have full control of the situation.  She had only been a dom for a
couple of years, but the mantra of the dominatrix is, "control, control,
control." She had lost it, right then and there.

   Instead, Ava sighed and motioned them into the entryway.  The girls took
off their coats and shoes.  Noelle was wearing a sundress and Megan a
blouse and skirt...typical blah clothing provided by their conservative
parents, and quite at odds with what usually went on in their current
location.

   Both Ava and Noelle were brunette, tall and slim.  Perfect for the job,
Ava had been told.

   Ava had never liked Megan.  The curvy sandy blonde had caused Ava all
sorts of problems growing up, such as going through her stuff and tattling
when the older girl did or had anything her parents would have disagreed
with.  Megan looked innocently at Ava.

   'Well,' Ava thought to herself, 'it's been a few years...maybe she's
changed.  It's not like she would want to get her best friend in trouble,
and Noelle was the one who asked for my help.'

   "Come with me," Ava said, heading toward her work room, "and keep it
down!  This could be a shock."

   She opened the door and entered.  There, before them, was Congressman
Adam Delphy, tied down to a weightlifting bench on his back, naked, his
hard cock pointing toward the ceiling.  The girls couldn't tell who the man
was because of the full-face gimp mask and ball gag he was wearing, and he
couldn't hear their gasps because of the noise suppressing ear protectors
Ava had put on his head.

   Ava was in work mode now, so got to it, grabbing her riding crop and
giving the Congressman a smack to his thigh.  With no way to see or hear it
coming, he jumped at the impact.  His cock never wavered.

   Ava looked back at the girls.  They hadn't gotten past the doorway,
their eyes as big as saucers.  She waved them in, and they shuffled in
slowly, standing behind her.

   "Stand here and here," she commanded, moving to the foot of the
weightlifting bench and pointing to either side of it.  The girls did as
she said, as all her clients did when she used that tone.  She had control
back.

   She slid the riding crop up Adam's inner thigh, across his six pack abs,
and then back down his other thigh.  For an older man, mid-forties, Delphy
kept himself in good shape.  Ava was glad he was here this week instead of
some of her other clients.  Some of them weren't much to look at.

   She pointed at his cock.  "Have a look," she said.  Both girls bent down
only a little.  "Get down on your knees!" she commanded.  They did.  Adam's
cock was no more than 2 feet from either of the girls.

   Ava continued, circling the riding crop lightly around Adam's private
parts.  "This is a penis.  I expect you haven't seen one before." Both
girls shook their heads.  "When a man and a woman are going to have sex,
the man's penis fills with blood and gets all erect like this.  It looks
intimidating, but is actually quite warm.  Noelle, touch it."

   Noelle looked at her older sister with fear in her eyes.

   "Do it!" Ava commanded.

   Noelle reached out and tentatively poked the side of the cock with her
index finger.  It angled away and then bobbed back.  She giggled.  Growing
bolder, she lightly grasped it with her hand.

   Adam's head tilted up at this.  Ava never fucked her clientele, and
rarely played with their junk, so this was unexpected for him.  Ava smacked
the crop across his nipples and he laid back.

   Noelle was enjoying touching her first cock.  "Try it, Megan," she said,
letting go.

   Megan took Adam's cock in her hand, marvelling at the paradoxical
firmness and yet softness of it.  As she held the penis her eyes roamed the
man's sexy restrained body.  Her panties quickly got wet at the thought of
what she was doing.  She started to slide her hand up and down his shaft,
eliciting a stifled groan from the man.  She quickly let go, looking up at
his mask-covered face.

   Ava continued her lesson: "When a woman is ready for sex her vagina, or
pussy, will produce moisture, or she may require some additional
lubrication.  At that point the man's penis can push into the woman's
vagina, aided by that lubrication."

   Megan looked at Adam's cock, incredulously.  "How can that fit?!  It's
so big!"

   "Some men's penises are smaller and some bigger," Ava told her.  "This
man's is about average at 6 inches in length, and not too thick.  It can
easily fit most women, if their vaginas are lubricated and ready."

   Megan looked at Adam's hard cock, thinking about it sliding into her
private place.  She felt a throbbing sensation down there.

   "Okay," she said, looking back up at Ava, "how does it go in?  Show us."

   Ava was taken aback by this question.  The plan had been to get them
used to touching cock, and then maybe she would allow them to whack her
client off if they weren't too freaked out.  She looked at her sister, and
Noelle was looking expectantly back at Ava as well.

   Control.  Ava wasn't used to anyone telling her what to do when she was
"in the zone".  She had also found herself quite turned on by the
juxtaposition of these innocent teenagers playing with her client's cock as
he lay there in bondage.  Because of this she wasn't thinking right.  If
she had she would have stopped things right then and there.

   Instead, she dropped the riding crop and slipped her robe off.  Both
younger girls gasped again.  Underneath, Ava was clad in her dom gear: a
corset, fishnet stockings with garters, opera gloves, underwear, and
ass-kicking high-heeled boots, all black.  Pausing a moment for effect, she
removed her panties using the side snaps so she didn't have to undo the
garters, revealing her trimmed muff.  Her pussy lips were distended,
betraying her arousal.

   Ava moved up next to her restrained client, lifting her boot and placing
it on his lightly hairy chest, eliciting another grunt from him.  Both
younger girls moved to one side to get the best view between Ava's spread
legs.

   Ava used her fingers to gently pull her pussy lips open, noticing that
she had produced a fair amount of lubrication herself.  "See how wet I am?"
she asked.  The girls nodded their heads.  "You can also see as I hold the
lips open that my vagina is bigger than yours are normally.  It stretches
to accommodate a penis."

   "Do it..." Megan said, entranced, staring.

   Ava seemed to be in a trance herself.  She moved her other foot back to
the floor so she was straddling Adam's pelvis, facing his feet.  She lined
up the cock with her cunt and moved her hips down.  Her inner pussy lips
had just started to surround Adam's cock head when she came to her senses
and stood back up.  What the hell was she doing?

   "Heyyy..." Megan whined, "show us!"

   Ava got off of Adam and stepped to the side.  "I don't have sex with my
clients," she stated, crossing her arms.  Now that she had come to her
senses again she had just realized why she was so wet, and had almost lost
control: it was her fertile time of the month.  Even touching the tip of
Adam's cock to her inner pussy lips might have transferred some
sperm-filled precum.  It was scary, but also strangely exciting.  Damned
fertile brain!  she thought.

   Megan looked at Adam's cock with undisguised lust.  "Well...can you show
me how it works?"

   "I told you..." Ava started to chastise the girl, and then stopped as
Megan unzipped her skirt, dropping it and her panties to the floor.  Her
puffy pussy was clearly very wet, almost dripping.  Noelle gasped at seeing
her best friend act like this.

   Ava was torn, but this situation was getting really fucking hot.  "I
don't know..." she said.

   Megan, always one to push boundaries, clambered to straddle Adam's hips,
facing his feet as Ava had.  His cock was right in front of her wet pussy.

   Ava's recent realization of personal fertility reminded her: "Megan..."
she warned, "I don't have any condoms here.  You could get pregnant." She
didn't keep any condoms on hand just so she wouldn't have an excuse to fuck
the clientele when she got turned on.  Until today it had worked.

   By this point Megan had lifted her hips up, and was rubbing the head of
Adam's cock along her pussy lips, stimulating her clit as they bumped
together.  She gasped, asking Ava, "You can have sex at certain times of
the month and not get pregnant, right?"

   Ava considered it.  "When did your last period end?" Maybe Megan was
close to her next one so it wouldn't matter?

   Megan thought for a moment.  "About a week ago...a little longer?" She
gasped as she managed to line Adam's cock up so the head dipped into her
wet pussy a little.

   Ava realized that Megan was right in the middle of her fertile time,
just as she was.  It explained Megan's wantonness.  As she paused at this
realization, the younger girl took advantage of the delay and managed to
get a couple of inches of Adam's cock into her virginal pussy.  She gasped
in pleasure and he grunted.

   Ava thought quick: 'I am a professional dominatrix.  Control is my
business.  I need to stop this.'

   Then she paused again, her mind flashing through the years of suffering
Megan had put her through.  She remembered coming home to find Megan had
gone through her diary and told her parents about the sexual things she had
written there.  She had found the Playgirl magazine a friend from school
had lent Ava, and had given it to her parents.  So many times Megan had
fucked her over; getting the older girl in trouble...sometimes she was
grounded and sometimes worse.

   Spurred on by her heightened arousal and sudden realized desire for
revenge, Ava made her fateful decision: Megan deserved some fucking (ha ha)
comeuppance.

   "It's okay, sweetie.  You're safe."

   Megan smiled, in that self-satisfied way she did when she got what she
wanted, rotating her hips to get Adam's cock deeper inside her.

   Ava knelt down on the other side of the bench from her sister.  Noelle
was unable to tear her eyes away from the sight of her best friend's pussy
getting penetrated by the restrained, nameless man's cock.

   Ava continued her sex education, feeling her control return.  "Look
here, Noelle...see that nub?  That's the clitoris, or clit for short.  If
it's stimulated it can help a woman to orgasm, which feels really good and
does some more things we'll talk about in a bit.  See how Megan's pussy is
able to take the penis inside her now?  She had rubbed the head of the
penis on her clit earlier, which stimulated it and helped her make enough
lubrication to do this."

   Megan raised her hips up and sank down on Adam's cock another couple of
inches.  She was shaking from the pleasure.

   Ava looked at Megan's rounded hips, what some call "babymaking hips",
and smiled.  Adam's cock had been drooling precum when Megan mounted him,
so there was probably already some sperm inside her.  Still, Megan might
not get pregnant with such a small amount...maybe Ava would tell her to get
off of his cock before he blew his potent seed deep inside her. 
Maybe...maybe not.  Ava liked this feeling of power over bitchface Megan.

   Finally Megan managed to get the whole shaft inside her, and settled
down on Adam's lap.  She paused to catch her breath.  "Oh, Noelle," she
gasped, "it feels so full inside me."

   Ava pointed to Adam's very full balls, dangling below his cock that was
currently deeply embedded in a fertile 16-year-old pussy, and continued her
lesson, "These are a man's testicles.  They hold his seed, his sperm.  When
a man orgasms, the seed comes from these and mixes with semen from his
prostate gland.  That mixture, called ejaculate or cum, rushes out the tip
of his penis, usually with great force.  This combination of orgasm and
ejaculation feels really good for the man."

   Megan had been watching the lesson as well, getting more turned on by it
as she sat on her first cock.  She raised her hips up again, allowing half
of Adam's penis to leave her wet cunt, before settling back down again. 
She did it again and again, building up a rhythm.  Her eyes were closed
now, her mouth slack.

   Ava continued, smiling knowingly: "When a man puts his sperm inside a
woman at just the right time of the month -- when her egg is released from
her ovaries -- there's a chance the sperm and egg will come together and
fertilization occurs.  The fertilized egg then attaches to the wall of the
woman's womb and grows.  They will have created life."

   Megan, tremendously turned on by the sex talk and her own fertile state,
bounced harder on Adam's hard cock.

   "Look at this, Noelle," Ava said, pointing at Adam's balls.  "See how
his scrotum, his ball sack, is pulling up toward his body?  That means he's
getting ready to cum, to ejaculate, to put his seed inside Megan's vagina."

   Megan was feeling really good, gasping as she bounced madly on Adam's
hard cock.  He was going to put his seed inside her!  What would it feel
like?  she wondered.

   Then she felt it.  Adam grunted, thrusting his hips upward.  His cock
thickened inside the teenage girl's unused pussy, and then it started to
spurt potent seed deep inside the unsuspecting girl.  Megan could feel the
warm liquid spreading within her.  At that moment Ava reached forward and
rubbed Megan's extended clitoris.

   As Megan exploded in orgasm, crying out in pleasure, Ava explained to
her little sister what was happening as she continued to lightly rub:

   "Megan is orgasming now.  Inside, her cervix is opening up, and some of
the sperm he's shooting deep inside her pussy is being pulled into her
womb. If she was fertile right now, this orgasm would really increase her
chances of getting pregnant and having his baby."

   Megan was shaking uncontrollably, her fertile body liking the idea that
a baby could be made inside her by this wonderfully pleasurable act, but
knowing that she was actually safe.  "Yes, yes..." she murmured as she
continued to cum on the dangerous, babymaking cock.

   Ava could take no more.  She reached down and started to frig herself,
watching the look of bliss on Megan's dumb face as her fertile pussy sucked
up Adam's potent seed.  Ava was already so primed by the naughty, sexy
display that it only took a few seconds and then she was gasping on the
floor in her own orgasmic seizure.

   When she was done Megan was still embedded on Adam's cock, bent forward
between his legs as she recovered.  On unsteady legs, Ava hobbled off to
the washroom to clean herself up.

   As she cleaned up her orgasmic juices she considered her next steps.  If
the Congressman was still up for it she might see if Noelle could be
convinced to give him a blowjob...

   She heard a cry from her work room.  She rushed in to find Noelle on top
of the Congressman, her panties on the floor and her sundress obscuring
what Ava knew was the loss of her little sister's virginity.

   Unlike Megan, she was facing toward Adam's masked head, crying on his
chest.  Megan hugged her friend, trying to console her.  Ava rushed
forward, trying to pull her sister off of her client.

   "No, no..." Noelle said, pushing her sister away and wiping her tears.
"I'll...be okay."

   "I want to see," said Megan, lifting Noelle's sundress.  Both Megan and
Ava bent down to see Adam's still hard cock pushed about halfway into
Noelle's pussy.  The sperm left from Megan's seeding had provided enough
lubrication to allow Noelle a faster penetration than her friend, and
consequently a quick deflowering.  Ava could see blood mixed with semen
pooling at the base of Adam's cock.

   The sperm...

   "Noelle, when was your last period?" Ava asked, dreading the answer.

   Noelle started to move on Adam's cock, flinching a little from the
soreness.  "Same as Megan...a little over a week ago.  I'm safe too," she
responded.

   It was too late...Noelle already had sperm inside her likewise very
fertile pussy.  If Ava stopped her now the loss of her little sister's
virginity would be for nothing, and the shock of the truth could destroy
her budding sexuality.  Ava resolved to do the best she could for her
sister, given the situation.

   They pulled Noelle's sundress up and off, leaving Ava's beautiful sister
in just her bra as she slowly bounced on Adam's cock.  Megan removed her
own shirt and masturbated while sitting propped up against the wall,
watching, knowing how good what Noelle was doing felt like firsthand.

   Despite the discomfort accompanying her maidenhead being ruptured,
Noelle was a real trooper, riding Adam until he spurted his cum deep inside
her, just like he had done with her best friend.  When Ava and Megan heard
him grunt and Noelle cry out in response, the other girls came hard again.
Ava wasn't even touching herself at the time, it was so hot!

   After the girls had left, Ava sat there, her head in her hands.  One or
both of them were almost certainly pregnant.  Her poor sister!  Their
parents would kick her out for sure, and then what?

   She answered her own question.  She would let her sister live with her,
of course, but how would they make ends meet with a baby on the way?

   The baby...of a Congressman...

   'Well, well...' she thought to herself.  A plan began to form in Ava's
mind...
