Katherine and Seraphine



   Seraphine blinked.  Dawn has crawled through the window and was tickling
her nose.  She yawned and turned to her side where her best friend
Katherine was still sound asleep.  The two sixteen year olds were similar
to an uncanny degree: Kate was the same height, had the same cute nose,
same sky blue eyes, same lithe legs, same beautiful hips and a matching
trim belly.  They even shared an identical beauty speck right beside the
belly button.  Their parents likely had trouble separating them, but
luckily Kate had long brown hair to contrast Sera's blonde maine. 
Seraphine's mustered her friend, her eyes were following the strands of
smooth brown hair, which was curled and unordered from the night, but it
did not lose its auburn glimmer nor its alluring scent.  One big strand has
broken free and rested upon Kate's mesmerising round breasts.  She was just
stunning.  No wonder the boys at their school turned their heads.  Maybe
they turned for Sera too since they do look the same but she could not care
less.

   Inching a bit closer the autumn scent filled her nose.  They had so much
fun yesterday.  Seras parents left their daughter home alone for an entire
weekend.  She had no other choice but to invite her best friend and have
some fun.  They ate Pizza, drank that thing which Katie brought...  oh yeah
was that alcohol?  It tasted weird though.  They gossiped and talked about
school; how Emma told them that Mike had a crush on both of them.

   Suddenly a ringing alarm sprang Katherine's eyes wide open.  For a split
second Sera stared awkwardly in her twins sky blue eyes, but then quickly
turned away.  "Sorryyy, " babbled Katherine, "forgot to turn off the
alarm". Sera barrel-rolled herself into her cover and replied with playful
anger, "Seriously Kate?".  "Yeah 'seriously Kate'." was returned slightly
annoyed.  "Besides it is half past eight anyway.  You have no reason to
bicker like an old cow.  Stand up!" Kate laughed and without warning a
pillow smashed against Seras backside.  "Heeyy!  Screw you!  Your old cow
sleeps for another thirty minutes or so." Sera replied.  Kate sighed.  She
went quiet for a second, probably working out a contract.  With a
ridicolous deep voice she started negotiating, "OK look sweet heart, here
is an offer you cannot refuse: I'm going to take a shower while you get
your beauty sleep.  And then we do something fun.  " "What if I don't?"
mocked Sera and turned her head towards the negotiator.  With a mischievous
smile Kate replied, "Like I said, it is an offer you cannot refuse.  Better
be out of the bed when I come back".  With that she turned on her heels and
left the room in her nighties.

   Shortly afterwards the faint dripping of the shower started.  Sera
scratched, streched, yawned and lied flat on her back.  Hopefully Kate did
not really notice her staring.  She was not really awake when that alarm
rang was she?  Her eyes were blinking, right?  A yawn crawled out of her
mouth and dreams slipping into reality until both were indistinguishable. A
sudden slam woke her up.

   Kate had closed her little suitecase and was almost fully dressed.  Sera
quickly rose and said, "Honey sorry I fell asleep again..." But Kate did
not react.  "Katherine, is something wrong?" Kate was stammering something
about having forgotten an appointment and how she will be back soon.  With
lightning speed Kate put on her sneakers and slammed the front door shut.
Seraphine stood there dumbfounded.  What has just happened?  Did I do
something wrong?  Did I weird out Katherine?

   Her heart ached.  What am I going to do now?  Seraphine was looking
forward to this weekend with Kate and now it all went to hell.  She went
downstairs.  Crunching at the extra sweet cornflakes did not lift her mood.
Sera's parents would not allow such sweet stuff, so they bought it for this
weekend only, and planned to eat the whole box.  It was meant for a
breakfast with Katie but now...  The half emptied bowl landed in the
kitchen sink.

   Maybe a shower would soothe her restlessness.  Seraphine smashed her
nighties in the washing bin and received a satisfying smash.  Her best
friend was here mere minutes ago.  The bathroom was still full of her
autumn-like shampoo.  She ruffled her blond maine while her mirror image
stared gloomly back at her.  Her gaze dropped and followed her slender
curve.  Had her breasts grown?  They seemed fuller, rounder than usual. 
Her hands glided over her chest.  Strangely the touch did not ache and burn
as the other times when her body decided it was "new bra time".  Her hands
moved down her smooth hourglass waist to the firm apple formed backside. 
Her figure really was indistinguishable from Katie's.

   The shower started dripping again.  Little streams wandered down her
body while a soothing warmth filled her head.  Katherine's perfume filled
her nose.  She closed her eyes and took a deep breath.  It was as if Katie
was next to her shampooing her beautiful brown hair.  She imagined Kate
kissing her neck.  One hand traveled to her chest and was gliding over her
soft breast, teasing her nipple while the other was slowly inching south,
touching her belly button and stopping over her smooth mound.  Seraphine
gasped as her fingers brushed her clit, carefully circling the hardening
nub.  Another gasp escaped.  All her worries were melting in the heat.  Her
other hand wandered down over soft lips into her virgin depths.  She felt
her trained belly tensing while her body was resting against the cool
shower wall.  The streams were pinching and tickling her skin.  Shocks of
electricity waved throuhg her body.  Seraphine was climbing towards the
edge of bursting and then...  she froze.  Her arm was pressing against
something.  Something which she felt pressing against her arn, which was
attached to her.  She opened her eyes.  Looking down her heaving chest she
saw a penis staring back.  Uncertain she touched the tip and immediately
gasped.  Sensitive!  Her sleek hand grabbed the thing and glided downwards.
It was almost too big to get fully encircled by her fingers, but she could
feel all five touching and traveling over her new organ.

   Dripping and dreamingly Seraphine stepped out of the shower.  Her mirror
image was telling the same story.  It was big like a cucumber directly
attached on her mound, just above her feminine lips and ended above her
belly button.  But unlike the dicks she saw on the internet it's skin was
thin, smooth and she was clearly missing testicles.  Fingers spreaded her
lower lips and reassured everything down there was still the same.  The
mirror image looked puzzled back at her.  Gears in her head were grinding
and creaking.  In a flash her brain started working again.  She had grown a
penis!  "Oh shit...  shit, SHIIT!"

   Katherine!  Katherine had to come and help her!  Somehow!  Sera sprinted
out of the shower, her new organ flapping against her slim belly and
grabbed her phone.  Thumbs flew across the display and a hasty message was
sent.  Her heart pounded while she stared at her display.  Katherine was
tiping a response.  A beep from her phone which brought the simple message;
"I know.  Be there in an hour.  I can explain".  Seraphine's mind was
spinning again.  What would her parents do when they see her like this? 
How should she ever go to the Swimmingpool again?  She glanced down to her
new tool and saw that it shrank significantly.  Now it was almost the size
of her palm.  But when her hand touched it, it immediately twitched and
grew again with every heartbeat.

   She had to breathe!  She had to calm herself.  Breathe out!  Her mind
became clearer.  Breathe in!  What can I do now?  Panicking is not going to
solve anything.  Everything I can do happens in the present, now.  Breathe
out!  Her heart calmed.  What ever happens, I am is still me.  And maybe it
will not be easy, but even the darkest night will pass according to Batman.
Breathe in!  What to do now?  She felt her cold wet hair clinging on her
skin.  First, she had to dry her hair and then find something to wear. 
Afterwards she had to wait for Katie.  Seraphine marched back to the
bathroom ignoring her flaccid penis slapping against her legs.

   She found herself in the mirror which showed young upper body.  Here it
was the same old same old.  She took the brush and hairdryer and started to
put them to their use.  Her gaze inspected the mirror image more closely as
the drying blonde hair was getting its shimmer back.  Her tits really
seemed bigger!  But her nipples seemed to be the same size.  Her arm
brushed the study objects which were a little bit smaller than
pencilerasers.  She dropped the brush and turned to look at her profile and
cupped one of her breasts.  Now she was sure, she had to look for D Cup
Bra's.

   If Katie's had grown too?  The last 'Braexplosion' was lead by Kate, it
took her almost two months to catch up.  Those were envious two months but
it was around the time when Katherine explained how she was doing it to
herself.  Afterwards Kate asked if they would do it infront of each other.
She touched her clit before but never reached an orgasm.  That day, she had
done the same thing as Katie, pulled back the little skin and started
circling slowly, been picking up the pace as she did and been plunging the
first two fingers as she did.  Seras whole body had been clinching,
trembling and then relaxing on a wave of pure pleasure she had never ever
felt before...

   Seraphine opened her eyes again.  Her nipples were stiff, her crotch
already warm and her belly button was overshadowed by her big throbbing
dick.  She took a step back and reexamined her new crotch.  Under the
massive cucumber were her puffy feminine folds in plain sight.  She watched
her fingers travelling up and down the lips while her clit was poking
outside.  Shivers!  A finger tingled the little buzzer, her body responded
immediately with a tingling wave spreading through her virgin vagina.  But
unexpectedly the tingling continued through her new penis and watched
mesmerized as she felt it pulse.  Intrigued Seraphine tried to stiffen her
new muscle, felt it building up pressure at the base just above her folds,
felt it pass along her cock, and saw the the blonde's mirror image penis
throbb.

   She gazed at her reflection, following her curvy figure upwards and
stopped at her now heaving breasts, grabbing them as if she was
daydreaming. Seraphine never felt anything like this.  This urge, the
prickling in her tits, the thightness of her crotch and the swollen dick
were overwhelming her senses.  She felt her hands travelling downwards,
from her breastd, felt them caressing her muscular belly, felt them
grabbing her vagina and the base of her cock.  She observed her aroused
mirror image sucking in air through her teeth, her chest rising and hips
buckling.  One hand has found her clit again.  The practised fingers
exposed it from its little skin and pinched the pulsating knob.  Her other
hand was rubbing at her base, slowly pumping its way upwards, grabbing the
cock tighter and tighter.  Seraphine moaned and swung her shimmering blonde
hair to one side of her neck.  This...this is...  oh my god!  The hand has
reached the sensitive red crown of her thick cock.  Under the feverish
pumping it seemed to grow even more.  She looked down to her jiggling tits.
Between her sinful hills were her bright red crown and her spreaded lips.
She stopped the circling motion, put her pulsing nub between middle and
Ringfinger and let it glide up and down between them.  The silky skin of
her clit responded with a violent electric pulse cramping her toes tightly.
OH MY GOD!  She felt her stomach muscles tensing from her clit rubbing,
felt her penis coming close to bursting, felt her tingling tits bouncing.
Seraphine groaned like an animal and then...  whole body shivered, her
vagina clenched and her cock throbbed in her hand as it spat thick white
goo on her chest.  The next throb splattered her firm belly and the next
one only dripped down her smooth cock on her hand.  Seraphine was panting,
That...  that was something else .  This is new, but if this is going to be
how I am then...  I can manage.  She looked in the mirror and saw herself
catching her breath but also smiling coyly while her whole upper body was
covered in goo.  It was salty, gooey obviously but also...  tasty.  Do I
produce real sperm?  Luckily Katie and I said yes to the pill.  She
couldn't resist to a second sample.  Afterwards she got herself cleaned she
realized that Katherine was coming in twenty minutes.

   Seraphine went to her room on the hunt for an outfit.  How should I
confine that snake in my pants?  Digging through her wardrobe yielded
almost no result.  Her black thong at least tugged it tight to her mound
and in combination with her baggies it was almost unnoticable, as long as
nobody 'rattled the cage'.  The pink hoodie concealed the rest, now she
just had to wait for Katherine.

   After what felt like an eternity the front door slammed again. 
Seraphine sprang up from the sofa, her bra free nipples brushed against the
pink fabric.  A faint taste of Katies autum perfume tickled her nose.  In
front of her was beautiful Katherine who was standing meekly on the corner
of the carpet.  "Seraphine...  I can explain..." she wispered, but her next
words ceased.  Her blue eyes were searching the carpet for words for some
time, but then without a warning everything was spilling out as if a dam
was broken, "Look I mean I like you but I thought you didn't like me in the
same way and there was this old lady who asked me if I needed help with
something and..." Sera zoned out.  Her friend was wearing a snow white
blouse which hinted at her gorgeous grown breasts.  Sera's face was rushing
with blood, she felt her breasts pressing against the hoodie and a warmth
spreading through her loins.  She felt the thong straining her new organ...
Did her breasts grow too?  She looked at the new black skirt.  Is that a
bulge starting to form?  She gazed into the frightened eyes of her twin and
asked "Did the same thing happen to you too?" Kate was caught off guard. 
The waterfall had stopped and without breaking eye contact she simply
replied "Yeah...  those were the 'wanted side effects' from the love
potion..." Kate's eyes turned to the floor.  "Seraphine look I am sorry
I..." Sera zoned out again.  A love potion?  Why a love potion...  the
brain finally shifted gears and grasped the situation: A love potion! 
Katie has a crush on me too!  She almost stumbled but managed to fall
around Katies neck, her firm breast pressing against her twin's.  She
finally kissed her crush.  Sera pushed her tongue past the strawberry
glossed lips and found Katherine's.  She had dreamed so many times how it
would happen, how this kiss would feel.  A hand was stroking her blonde
hair, their tongues were dancing in her twins mouth and the slightly rough
texture of it all!  It was so much better than she had ever dreamed.

   Seraphine got pushed and suddenly found herself lying on her back on the
huge sofa.  Katherine crawled on top of her with sparkling eyes and
Seraphine was kissed pationately.  She touched Katherines cheek, let her
fingers travel down over the neck and slowly into her lovers cleavage.  Her
fingers dipped inside the bra and found the pencil eraser sized nipple. 
Katherine moaned into the wet kiss as she started pinching and playing with
it.  Even in my wildest dreams...  this...  is just...  beautiful . 
Katherine's lovely hands dug below her sweater, travelled up the sides of
her hourglass figure slowly, taking there sweet time as they crawled up her
rib.  Sera's mind figured out the target of their travels, she arched her
back in anticipation.  The hands reached their destination and started
caressing her burning breasts.  Rubbing, playing, loving.  A hundred, no a
thousand butterflies swarmed in her belly.  There was no other place she
wanted to be right here right now.  But then in an instant Katherine pulled
her sweater off, exposing her hard nipples and penis tip.  Katherine simply
smiled and placed a finger on Sera's chin.  It traveled down her chin, over
her throat, down her cleavage, over her belly and up the tip of her penis.
Sera was looking into the lustfull eyes of her twin as she felt her cheeks
burn.  Two fingers traveled down her exposed length and over her still
dressed crotch, caressing her virgin vagina.  A little gasp escaped
Seraphine.  She felt the two fingers travel up again, tickling her folds
through the fabric, up her tender flesh to the tip and then down again
repeatedly as Katherine was biting her lips.  Sera loved this but in this
moment she hated her baggies.  The smooth hand travelled up and down, up
and down, up and...  Enough!  In one gracious move she pulled them plus
thong dowm and pushed everything clean off of her legs.  Katherine's eyes
widened.  Her mouth opened, shut and opened again while Seraphine could not
hide a little giggle.  A ginger palm touched Sera's smooth mound, right
below her base, traveled down to the valley tickling her clit, and then
again repeated to move up to her eager cock.  This is it!  Sera sighed and
sprawled her limbs.  She was enjoying every touch.  She saw Katherine
bending over, placing a kiss on her thigh.  She was tenderly kissing
upwards her wide hips, light abs and finally stoping at her breasts all
while her hand had kept busy.  Sera felt the tongue licking and suckling at
her hard nipple, teeth tugging tenderly.

   "Katie!  " slipped over her lips before Sera bit them, still covered in
leftover strawberry lipgloss.  Oh my lovely Katie!  She was stroking the
beatiful brown hair as Katherine eagerly kissed her way to her other
breast. Oh my KATIE!  You are still dressed!  She hugged the beauty and
rolled her over.  Now naked Sera was sitting on the top.  Katie looked at
her with her burning blue eyes and blushing red cheeks.  She just had to
kiss her.  Her lover's hands were brushing her blonde hair, but it was her
turn.  She pulled Katherine up without breaking the eager kiss and quickly
removed the blouse and bra.  Then Sera's hands glided over the waist, along
the perfect figure to the round and smooth breasts, grabbing, pushing and
pinching them.  Katherine immediately breathed heavier, but Sera was't done
yet.  With gentle force she pushed her love flat on her back and began to
kiss her way down to the mesmerising chest, gliding her naked penis down
the tummy,pressing against Kate's hard member.  This was feeling so right,
it was everything she had ever dreamed, lying naked ontop of her twin and
caressing the beauty's breasts.  She was kissing and licking the sensitive
skin around the nipple, playfully biting the eraser.  With her left hand
she traveled up her twin's thigh, under the skirt and crawled towarts the
panties.  Her hands brushed against Katherine's most feminine parts, felt
the clit slightly poking out through the silk and began to very gently
circle the bud.  Still burried in the breasts she heard Kate purr.  Her
twin's sleek hands moved quickly and suddenly her fingers caressed the soft
lips of her best friends naked vagina.  Oh my god this is hot!  Legs were
parting slowly.  Her hand moved upwards over her twin's shaved hill, up the
base of the cucumber, teasing the tip and with a drop of sticky fluid
travelled the whole way down, into the valley.  Kate panted as Sera found
her way inside, touching and exploring the walls.

   But suddenly Katherine grabbed her head, plunged her eager tongue in
Sera's open mouth and pushed her naked body on top of hers.  Katies perfect
legs were lying ontop of hers, her penis smashing against hers, her belly
resting ontop of hers, her breasts pressing against hers.  This is it.  I
want this.  Sera moaned in Katherine's ear, "I want you!  Take me!". 
Slightly distracted Katherine first kissed her again and then glided down,
her smooth skin dragging along the way, rose up and aligned her pulsing
penis with her virginity.  She felt the huge tip brushing her lips open,
kissing her clit and slowly pressing inside her, stretching her.  She felt
Katherine carefully pushing deeper, stretching her mound, stretching her
belly.  The crown was hitting...  "Oh my God" moaned Seraphine full of lust
as Kate burried the cock deep inside her.  Kate's smooth mound was rubbing
her clit at the same time as the crown was brusching against something...
amazing!  Katherine began to fuck her virginity away, their soft lusty
moans combining with each tentative thrust.  She felt the giant sliding in
and out, massaging every nerve as her vagina was getting filled to the
brim. She never felt this stretched...  this full.  Seraphine groped her
jiggling breasts.  Her cock was swinging around idly.  This was too slow,
her body could not get enough.  Sera needed it so bad.  Fuck this tentative
fucking!  She buckled her hips, swung her legs around Katherine's wide hips
and let her drop on her, pressing her feet against Kate's firm ass to spurr
her on.  Her cock was sandwiched between them drooling on them.  Now
Katherine got the message and picked up the pace, pounding her hole,
kissing and sucking her neck.  Seraphine's toes clenched.  Her vagina
tightened and pressed down on Katie's cock.  She felt the swollen tip
getting dragged out just to get slammed back in.  Every time the smooth
crotch rubbed her pulsing buzzer, shocking and trembling her legs and up
her belly.  She was on the edge.  Sera laid her head back and screamed. 
Katherine grabbed Sera's breasts, moaned, kissed her neck and stuffed her
pussy just a few more times.  "Katie, Katie!  KATIE!!!" Her whole body was
trembling, pulsing cock stretching her insides, getting pushed inside
until...  "OOOH!" Electricity raced through her.  Her belly was undulating,
milking the thickness inside her and then prickles washed over all her
muscles, relaxing her legs, her strained stomach, and tickled the base of
her cock.  A little drop drooled down her lenght.  I am not finished... 
yet.  She brushed her blonde maine out of her face and looked up to Katie
who was a mess too.  Her hair was wild, still panting, moaning, probably
riding out her own orgasm.  But her eyes were still burning with desires.
To her surprise Katie pulled out the wet length, hugged her and rolled them
on the sofa.  Kate had a wicked smile on her face.  Still panting she
wispered "Now...  TAKE me!"

   Sera bit her lips again, she pressed her clit against the still wet cock
and slowly slided it's length downwards.  Another wave prickled through her
buzzer up to her stiff dick.  This is amazing!  Katherine buckled her hips
and wrapped the long legs around her waist as Sera did before.  Seraphine
let the tip run through her twin's valley, caressing the clit and then
pressed her hips forward.  Her brown haired twin was eager, and pressed
against her round cheeks, urging her to push harder.  It was tight,
unbelievably tight.  Her thick crown stretched its way trough.  Then she
hilted herself inside Katie, lying flat on her twin with the wet cock
dripping a few drops on their bellies, and their tits pressed tightly
together.  Sera began to pull out, just to slam back again, restretching
the insides.  Urged on by eager groaning Kate Sera fell into a fast rythm.
But her body started right were Katie's cock left, she felt a prickling
wave, but this time it was radiating from the tip of her cock.  Already she
was getting close to the edge.  She grabbed Kate's jiggling tits for
support, felt Kate's hard nipple press in her palm and arched her back from
the overwhelming sensation of ploughing Katherine's tight, wet vagina.  She
felt the walls tightening even more around her flesh.  Her sensitive tits
were groped and Kate's smooth hands.  Sera closed her eyes, Kate's smooth
hands glided etween the bursting pressure in her cock, her own moans she
heard Katherine reduced to shouting "Seraphine!  SERAAaaah".  Her own
pressure released, every muscle was relaxing but she did not feel anything
flowing out.  She had probably 'No Ammo' left.  Exhausted she pulled out
with a yelp from Katie and dropped beside her twin, breathing heavily but
finally and completely satisfied.

   Sera's blonde maine was stroked and brushed out of her face.  She looked
at her brown haired mirror image, smiling at her.  Her beatiful breasts,
suckable nipples, drooling and relaxing cock and shining legs.  "That
was..." "...  amazing" finished Kate and giggled.  "Oh man Katie all this
time I had such a crush on you, but I thought you liked boys!" "Oh god no,
but I have to admit I really like your...  you know..." Seraphine had to
giggle too.  But then a thought crossed her mind and she had trouble with
the wording.  Smiling shyly she asked, "So...  are we together now?"
Katherine brushed her cheek and wispered "Yes".  Her lips were kissed and
her heart jumped.  "Now Katie, mind explaining to me how we got this?"
