   The Oral Knot By Randall Keldric@hotmail.com

   I am a female.  Some would call me a pervert or a slut.  Others might
just think I'm sick or I need help.  But I've read stories out there that
have similar tastes as me.  If people are writing them, and others are
reading them, then I'm not alone in my desires.  So, I thought I'd tell you
mine.  First, a little background info.  I'm a tall, 27 year old female
with black hair, brown eyes, and medium c cup breasts.  I've been told I
look like a porn actress named Essy Moore.  Only my breasts are a bit more
perky and my hair is longer...  and of course after watching her I do not
have an English accent.  lol

   By day I am a nurse.  In my private life I have both a medical fetish
and a love for cock of the 4 legged variety.  I also absolutely love giving
head.  There is something about it.  I don't know why, but it turns me on
like crazy to have a cock in my throat squirting hot loads of cum.  Before
you ask, yes I have given my doggie a blowjob on several occasions.  The
only thing is I could not let him knot up in my mouth of course.  There is
this silly little thing I like to do called breathing.

   I tell you all this because it explains how I came to be in the
situation I was in a few short weeks ago.  I was doing inventory and came
across something very interesting.  It was a box of tubes about 1/2 inch in
diameter, about a foot long, and had one very smooth end and the other end
was bent almost 90 degrees and then had about 2 more inches of tube.  They
were labeled breathing tubes, but I had never seen one used or heard of it
so I asked one of the doctors.  He said that the reason I hadn't seen them
because they are rarely used.  Typically if a patient needs to be tubed to
breathe, the tube is inserted in their mouth and down to the lungs.  These
are for the rare special case that if something is badly wrong with the
mouth and they need to be tubed, these are inserted through the nostril and
down into the lungs.  It this way the patient can still breathe or even can
be tubed by hooking a ventilator to these while the mouth is repaired.

   My mind immediately put 2 and 2 together.  Hospitals don't keep nearly
suck tight control over plastic tubes and other disposables as they do on
drugs, so I managed to acquire 2 of them with no one knowing.  They are
pretty inexpensive, but I still felt guilty taking them, so I did work a
couple of hours overtime and then did not mark it on my pay card so I paid
for them that way.

   I purchased a rather soft and not too long dildo and started working. 
At first just putting one of these in was almost impossible as I almost
immediately felt an uncontrollable need to cough.  But, every day I would
insert one 3 or 4 times, sterilizing them between each try.  It was so damn
difficult that after a month I gave up and put them aside, but I decided to
try again after 2 weeks.  I kept trying and trying, each time being able to
keep them in longer and each time having less sore throat after taking them
out.  Finally after a few months I finally worked myself up to being able
to keep them in with no problem for quite a while.  Then came the next
step. This was not nearly as difficult but still took a bit of time to
master.  I had mastered and pretty much done away with my gag reflex many
years ago, but now I needed to put it all together...  the breathing tubes
in my nose and down my throat to breathe and then the soft jelly dildo
slowly down my throat, then leave it there and breathe.

   That took some time too.  It is completely and totally unnatural for the
human body to close the throat to swallow and try to pull in air.  It means
definite choking in any situation except this one I have created, and thus
my body, my brain, my natural responses all fought me in every way
possible. And finally, after over 7 months of practice and getting used to
everything, I was finally ready.

   I have been a dog slut ever since I gave my virginity to one a long time
ago, but that is another story.  Unfortunately I live in an apartment that
frowns on pets and certainly would not allow any dogs of any size, but it's
what I can afford now.  But my parents live about 45 minutes away and they
live on a nice large piece of land.  The 2 acres behind their house is
fenced in and I have my 2 wonderful dogs that I left with them when I moved
here, but i do go home most weekends.

   The coming weekend was their 30th wedding anniversary.  I had convinced
dad to take mom on a cruise to celebrate.  They were taking a weekend
cruise, leaving Friday and coming back Monday.  i told them as soon as I
got off work Friday I'd come over to watch the house and take care of the
dogs.  We had 2 dogs, Rex and Toby.  As you can imagine I practically flew
over to their house.  When I got there, I quickly took my bag and went in,
locking the door behind me.  The fence around the back joined the back of
the house and there was a large doggie door in the back door so the dogs
could come in anytime they wanted, so they were both inside and waiting for
me the minute I got inside.

   I don't know who wanted who more?  Both of them knew what was coming,
their cocks already sticking out of their sheathes a couple of inches.  I
went to my room, locking them out for a minute.  I carefully inserted one
tube in each nostril.  I really only needed one, but better safe than
sorry. One I got them in and where I wanted then, I put some tape on then
and my nose to keep them from slipping.  My pussy was dripping already.  I
wanted this so badly.  I had been wanting this for such a long time.  I
took off all my clothes and put them on my bed.  I then put on a pair of
kneepads I had.  I was ready.  My pussy was so wet as I opened the door
that it was dripping.

   I opened the door and they practically knocked me down.  I held myself
up and them away.  I started walking to the bathroom and picked up a couple
of towels, then headed for the family room.  The family room had both a
hardwood floor (no staining the carpet) and an absolutely wonderful
ottoman. Rex managed to get his nose in my ass as I walked, licking me with
that long tongue from clit to asshole.  I practically fell forward then.  I
put both hands out, holding the walls to steady myself.  Toby took this
opportunity to start licking my pussy from the front.  Fucckkkkk...  The
wave of orgasm hit me.  Their tongues working me, one from clit to ass,
then the next from ass to clit, competing for every drop of my pussy juice,
which was flowing like a river.

   I don't know how, but I managed to stay upright.  As the orgasm slowly
faded, I pushed my legs together as hard as I could.  My arms and legs were
quivering.  Damn, I needed a cock in me so very bad.  I started making my
way down the hall.  Their licking was relentless.  Somehow, some way I
finally made it, and by the time i did they had me almost ready for another
orgasm.  I found out years ago I'm a multiple cummer.  Once i get started I
can orgasm many times in a row.

   I fell forward onto the ottoman.  Immediately I felt the wonderful furry
weight on my back.  I wasn't sure which one it was.  I didn't care.  I only
cared about feeling a hot cock in my desperately empty pussy.  I wasn't
disappointed.  I felt the cock poke me on my left butt cheek, then again
closer.  I shifted myself toward his cock and felt it hit my pussy,
spreading my lips open.  As e felt his cock start into me, he stepped
forward and pushed it out at the same time, ramming the entire length into
me.  Immediately his pokes turned to a frenzied humping, driving his cock
as deep in me as he could get it.  I pushed back against him, arching my
back and trying to help him get as deep as he could.  In moments I felt his
knot swelling inside me.  As he humped his swelling knot against my g-spot,
my second orgasm hit me.  I had planned to wait to start cumming till I had
a cock in my mouth.  Lol...  so much for plans.

   As he shook my body forward and back with his humping, I lost myself in
ecstasy.  It felt sooo good, his hot cock in me, hammering deeper and
deeper, spurting his hot precum, swelling more and more till it eventually
locked in place, stretching my pussy.  I could feel it still growing bigger
around and longer.  Soon it grew long enough to touch, then push against my
cervix.  As it kept growing, he slowed humping, stopped, and just laid on
my back.

   Then I felt my face being licked.  I opened my eyes and toby was in my
face licking me.  I glanced up to see Rex, tongue lolling out, panting and
resting and enjoying breeding his bitch.  Rex stepped off of me and spun
around, dragging his hind leg across my ass and then standing ass to ass
with me.  I reached out and stroked Toby's cock, semi hard in its sheathe.
As I stroked him, he began humping a little.  I kept teasing him as he came
closer.  In a moment he hopped up on my head and shoulders trying to mount
me.  This has happened many times and usually whichever one of them does
this was rewarded with my holding his knot in my hand and his shaft in my
mouth, but not today!  Today was the day I gave my forst real doggie
blowjob.

   As he poked his cock forward, I opened my mouth and let him go in. 
fear, passion, a wave of all kinds of emotions swept over me as he felt the
hot wetness of my mouth and stepped forward, pushing his cock in my mouth
up to his sheathe.  He immediately started swelling as he humped my mouth
hard, his shaft starting down my throat.  A short wave of panic hit me and
I almost pulled him out, but no...  I had been waiting for this...  worked
for this...  wanted this so badly...  And in only a few seconds the knot
grew large enough to make the decision for me.  It swelled against the roof
of my mouth and my tongue, forcing my mouth open wide.  I grabbed him to
try to stop it moving lest it grind back and forth on my teeth ruining it
for us both.

   It grew more and more till soon I was regretting it.  My jaw was forced
as open as I could get it.  His knot swelled and pressed on the roof of my
mouth on top, and pressed down forcing my tongue hard down to the lower
part of my mouth and locking in place.  As he slowed and then stopped
humping, his knot forced my jaw as open as it had ever been while his shaft
grew further and further down my throat.  I made sure it went down the
right way, swallowing as it grew.  Soon he was full size, his knot fully
opening my jaws beyond anything close to normal and his shaft, hot and wet,
deep down my throat.  As he stepped off my head I grabbed him, thought for
a moment, and made his go the correct direction so as he turned I could
just raise my head and lay it down on the other side.

   You see, dog knots are not round.  They are much wider on each side, and
they stick up on top, but the bottom is practically flat, so his knot was
one side against the roof of my mouth and one side against my tongue. 
There was absolutely no way his knot could spin in my mouth so i had to
turn my head from the left cheek down to the right cheek down as his body
spun.  But I accomplished this and now I was finally doing something I had
only dreamed possible.  I had a dog cock tied tightly in my pussy and
another tied tightly in my mouth.  I felt the one in my pussy starting to
spurt load after load of his hot cum spurt hard out of his cock, and it was
so tightly against my cervix I think it was spurting directly into my womb.
I knew some of it had to me.

   Then I felt Toby start to cum into my throat.  I could feel each load go
through his cock and spurt out hot and wet deep in my throat.  He was so
deep in my throat I neither tasted it nor did I really have a choice in
swallowing...  not that I wouldn't have swallowed anyway.  I always did. 
But now...  2 cocks in me...  both ends...  knotted...  and both cumming...
This thought was all I could handle as I began another orgasm.

   As I gave myself to wave after wave of orgasmic bliss, I became aware
that someone was playing with my right nipple.  Despite the shock of it, I
was too far gone in orgasm and it was a tongue on my nipple and it just
server to make me cum harder.  I couldn't stop the wave after wave. 
Finally it stopped and I realized it felt a lot more like an animal tongue
than a human's.  I then saw a large mutt walking around looking at me.  I
still was being licked on the other side.  I couldn't turn my head so I
just had to assume there were 2 more dogs here.  I had no idea where they
had come from.

   Then I suppose the smells or the sounds or whatever got to the black one
as he hopped on my side to mount me.  He poked air for a while next to my
ribs but then hopped off.  I felt the one on the other side do the same. 
They kept hopping up on me here and there, and I have to admit it was an
even greater turn on.  I mean, I had dog cock in my pussy, dog cock in my
mouth, and 2 horny dogs wanting to fuck me in a bad way.  Both the other
dogs were getting desperate...  jumping on me...  even jumping across me...
My 2 dogs pulled a bit, I suppose trying to get further from them.  So, I
was in a tug of war between my mouth and my pussy.

   Then something totally unexpected happened.  In all the jumping, one of
them had managed to mount me correctly and I could feel his cock poking
around my already completely filled pussy.  A moment of panic hit me.  I
knew if he managed to get into my pussy that he and my dog's cock would
surely rip me open internally.  I tried to move but either of my dogs was
stronger than me and now with both of them pulling me like this, there was
absolutely no way I was moving even an inch.  I tried reaching back, but
with my head pulled forward so and my body against the ottoman I couldn't
get to him.

   Suddenly his cock hit my asshole and went in an inch or so.  This was
all he needed.  Before i could even think or try to react, he rammed the
length of his cock deep into my bowels and began humping me hard and fast.
I didn't want him to knot my ass, at least not with a huge knot in my
pussy, but I had no choice what-so-ever.  His belly was slapping my ass and
his cock was quickly swelling inside my ass.

   I'm not sure if he was the size of a softball or if the knot in my pussy
made his knot in my ass feel bigger, but he swelled and swelled as he
humped.  Then as he slowed and stopped, his cock continued swelling.  I've
never been so stuffed full in my life.  And as the knot in my ass kept
swelling, it began pushing down on the knot in my pussy, trapping it
against my pelvic bone, and trapping my g-spot between my pelvic bone and
Rex's knot.

   Somewhere in my mind I thought of how fucked in a bad way I'd be if he
tried to turn and got in a fight with Rex while in me and so i reached up
and grabbed for him.  I was relieved to feel a collar and I pushed my hand
through it beside his head.  This is the last thing I remember as my body
was pushed into a state of orgasmic bliss.  The cock cumming down my
throat...  The cock in my pussy, cumming and throbbing and pulsing against
my trapped g-spot with each load, the cock in my ass growing and growing,
the knot getting ever larger and the shaft going deep into my belly.  I
went into orgasmic sensory overload.  My body spasmed with wave after wave
of orgasm.  The pain and pleasure all mixed.

   My orgasm lasted a long time, and just as it was starting to subside,
the dog in my ass started cumming.  This renewed and intensified my orgasm.
I've never started cumming before I stopped before.  I've never felt
anything so intense.  Each wave of bliss started from my pussy and just
flowed out to every point of my body.  Wave after wave over and over flowed
electrically through me, carrying me higher and higher.  At some point a
small part of me realized i was cumming so hard I was literally crying.  I
just continued to be taken by wave after wave of bliss.

   I'm not sure how long I was cumming.  I began to slow down and float
back into my body.  I still felt little orgasmic electric shocks from his
cock pulsing my g-spot.  We stayed like this for a while.  It was some kind
of pleasure-torture.  That's the only way I know to describe it.  I have a
cock cumming in my throat turning me on.  I have a cock cumming in my ass
turning me on.  And I have a cock in my pussy turning me on.  And...  like
that's not enough...  his cock is pressing so hard against my g-spot that
every spurt of cum massages it as it's forced through the cock, sending
constant little shocks through my body.

   I was not cumming in that extremely hard normal way, but every squirt of
cum against me was a kind of never ending orgasmic aftershock.  Spurt after
spurt pulsing my g-spot and then being deposited through my cervix and
directly into my womb.  Spurt after spurt in my ass and throat as well.  I
was in absolute complete total bliss.  The words do not describe it.  And
thinking about it: being forced to keep cumming, being filled in every
hole. Fuck it was as big a mental turn on as a physical one.

   We stayed like that for what felt like days.  Part of me couldn't take
it anymore but another part would have done anything to have kept it up. 
But finally I felt my orgasm stop completely.  I collapsed on the ottoman,
more completely spent than I have ever been.  I realized Rex had shrunk and
was pulling his cock out.  It came our with an unceremonial plop sound.  I
was now sure he'd gotten his cock tip past my cervix as not a lot of cum
ran out.  Then the dog in my mouth started shrinking.  Soon he pulled his
massive cock from my throat.

   My jaw had been so far open for so long I couldn't close it.  It hurt to
try even.  But I began working it till it moved a little.  I felt the furry
weight on my cheek and realized the 4th dog wanted to get his.  Part of me
wanted to pull away, but another part was truly getting off on being their
complete slut.  I couldn't move my head anyway with his weight on it.  I
was so completely exhausted I am not sure I could have moved it if he
wasn't there.  But, I thought he will probably not manage this without help
anyway.

   He poked thin air with his cock tip, squirting his precum on my face and
hair.  In a few seconds he hopped off me and sniffed my face, then licked
it.  Then he hopped back up, showering my face and hair again with hot
precum.  Then to my surprise he managed to get near my mouth.  After
squirting precum both all over my face and into my mouth he hopped off me
again.

   I managed to turn my head a but to put my mouth closer to the edge.  I
didn't realize how stiff my neck was from being in that position till I did
this.  My neck and jaw ached.  Maybe I need to not...  My debate with
myself was interrupted by him on my head again, holding and humping.  I had
moved my mouth where he was looking for it and so he found it.  I had no
strength to do anything.  I couldn't lift my hands, especially the right
one as my shoulder ached badly to even try.  And i couldn't even close my
mouth.  I did close it a little, but his cock had already felt it's wetness
and this only spurred him on.

   He stepped forward, pushing his entire cock down my throat and humping
hard.  I swallowed his precum and let him completely use my mouth.  His
knot immediately began swelling in my mouth.  Fuck...  despite my
exhaustion and pain here and there I wanted him in my mouth and cumming
down my throat so badly.  I waited with desire as he shoved his ever
growing cock and knot deeply into my mouth and throat.  Soon his knot began
swelling against my tongue and forcing my mouth open wider again.  It truly
hurt my jaws as his knot forced my mouth ever wider.  He was also a much
larger pre-cummer than toby had been and I was swallowing, being stretched,
and feeling his shaft starting down my throat.  Soon he had my mouth jacked
open even wider than it had been previously, his massive knot swelled tight
against the roof of my mouth and inside my teeth and against my tongue
shoving it downward so that I could actually feel the flesh on the bottom
of my jaw jutting down.

   His shaft spurted and got longer.  spurted again and hit the back of my
throat, spurted again and went partly down my throat.  I swallowed hard
getting both massive amounts of precum and his shaft down my hungry throat.
He kept getting longer and longer.  He was a smaller dog than Toby in
height, but he was far bigger in cock size.  It felt like it went down my
throat to my stomach.  Soon I was just feeling the cum passing through the
shaft and being jetted out far down my throat.  My jaw wasn't made to do
this, but it was so very very hot.  Again I had a dog in each end of me
trying to cum so much that it would meet in the middle.

   I managed to move my hand down under me to my clit.  I very gently
rubbed it, slowly, feeling the feeling of both cocks.  Feeling the gentle
touch on my finger slowly around and around my clit.  Despite my jaw, it
felt so wonderful.  It lasted for a short time before I felt the dog in my
ass stop spurting cum into me.  In another few moments he began shrinking
and then pulled his cock free from my ass.  A wave of hot cum followed it
out of my ass, running down and flooding my pussy and covering my hand.

   For a short while I lay there, slowly touching myself and enjoying the
deep cock spurting cum into my throat.  Then without so much as a warning
lick another dog landed on my back, his cock jabbing at my pussy and ass.
On the 3rd try it found my pussy and he stepped forward and pistoned it all
the way in.  He was spurting and swelling and almost instantly I felt his
knot growing inside me.  He kept humping it back and forth in me till it
swelled so massively that it locked into place.  Very quickly I felt his
shaft touching my cervix, then getting longer and longer and pushing more
and more till it pressed through and was squirting precum deep into me.

   I began cumming again, my body jerking against the 2 cocks.  I let it
take me.  It was not the powerful orgasms I'd been having, but more a slow
floating to ecstasy king of orgasm.  I came for a little while, aware of
all that was happening to me and then also not always.  Then it slowly
ended.  I ached from cumming so much.  Once I finished my orgasm.  I pulled
my arm from under me and just completely relaxed on the ottoman.  I had no
strength left, no orgasms left...  no anything left.  We stayed there for a
while, my stomach and womb getting fuller and fuller.

   I don't know how much longer i was there, but I felt the dog in my pussy
shrinking and then pulling free of me.  With this one some cum came out,
but I could still feel the hot sticky lake in my womanhood, deep in me,
looking to make puppies.  Then suddenly a jolt went through me.  A hot
rough dog's tongue on a horny clit feels good and often brings orgasms.  A
hot rough dog's tongue on a clit after a few of the most intense orgasms
possible is beyond too sensitive and painful.  I jerked away from him hard,
causing the dog in my mouth to try to go forward, pulling me hard across
the ottoman.  With the second lick I had nowhere I could go and the intense
feeling was far too much.  Then a second tongue joined and a dog jumped
onto my back.  He was sideways and missing the mark badly, but he was also
heavy enough to prevent me from getting my hands under myself for
protection.

   I tried to scream, but it just came out the tubes as Mmmmmm mmm m mm.  I
tried desperately to push my hands under me to my poor clit, but I couldn't
with him on me.  Oh Fuck it hurt.  I can't cum anymore.  I can't take this.
I Fucking Can't!!  Please!!  It all came out as mmm mmm mmm, but I was
thinking it all...  Could I do anything to get away.  Could I possibly lift
this damn fucker off me for 3 seconds.  OH!  I can't.  No.  I don't have it
in me..  No!  Noooo Pleaseeeeeeeeeee eeeeee Argh!!!!!  The orgasm hit me so
hard I couldn't do anything.  My whole body locked tightly into place.  I
was rigid as a piece of steel as wave after wave racked my body.  In a few
seconds I felt the one on my back hit the mark and force his cock into my
asshole.  It no sooner went in than the knot started swelling as he humped
me hard and fast.

   I was already beyond thought, beyond anything but wave after wave of
orgasm.  Then the added swelling and pulsing in my ass pushed me over the
limit.

   The next thing I remember I was crying and drifting.  I'm not sure why I
was crying.  I wasn't sure of anything.  Slowly I began to come to my
senses and remembered where I was.  My jaws were aching beyond belief, but
there was no cock in my mouth.  I suppose he'd finished and pulled out.  I
still had a doggie cock pumping me full of cum in my ass.  I guess I was
out a while, because I felt him slowing and then shrinking.  He pulled his
cock out of my ass and another gallon of cum ran out of me, across my pussy
and down my inner thighs, and into the towel under me.

   I somehow found the strength to roll sideways off the ottoman and into
the floor.  I fell back to sleep.

   I awoke later that night, shivering in a puddle of doggie cum.  I
managed to get to my feet and staggered through the house toward the
bathroom.  I noticed a note that had been pushed through the mail slot on
the front door.

   "Hi Jim and Lisa, I've been called away on a business trip for a couple
of weeks.  I hate to impose, but you told me if I ever needed a place for
the dogs, they could stay with you.  Sorry to just leave them, but my boss
made it clear that I would be on the plane tonight.  Anyway, I knocked but
no one came to the door and I see your car isn't here anyway, so I'm
leaving this note just to let you know they're here.  Thanks and sorry
again for not giving you any notice.  Paul"

   Ok, that explained the other 2 dogs.  I went on to the bathroom where I
sat on the toilet and let another gallon or so of cum run out of me.  I was
working the whole time to get my mouth closed again, which I finally did
but wow was my jaw sore.  I pulled the tape off and pulled the tubes from
my nose.  I then took a shower and collapsed into the bed.

   As I drifted off to sleep, I thought of all that had happened today.  I
knew it would be a few days before I tried oral again, but I have an ass, a
pussy, 4 dogs, and a couple of weeks.  And today was just day one...
   The end (For now anyway...  want more?  make a request)
