   SARAH, YOU ARE SUCH A CUNT (REPOSTED EDIT, MF, BEST)

   We had fucked before I showered, dressed and left to go to the office.
Unfortunately I soon had to come home to pick up some important papers that
I had forgotten.  I couldn't believe it when I opened the lounge door and
saw that you were on your knees with our dog's cock buried in your cunt. 
You were gasping, clearly on the edge of cumming, as he rammed his big cock
into your cunt.  You didn't even register my presence, all your attention
was on our dog's cock that was fucking you hard.

   Casting my mind back, it was only a few days ago, surely not a week
even, that I had first discovered your penchant for the dog's cock when I
came home early and found you "in flagrante" with the dog.  This too was
after I had filled your cunt with my spunk before I left for work that
morning.  You looked up at me.  I said "Sarah, you are SUCH a cunt". 
Later, you sobbed; you told me that it had never happened before and it was
completely spontaneous, you blamed me.  You told me that it had only
happened because you were wearing a tee shirt with no skirt and no knickers
(I could understand the last part because you don't have any knickers), and
that you had been trying to retrieve a lost pen from under the sofa when
the dog had started to lick your naked, and available, cunt.  You told me
that as well as licking you to an orgasm he hadn't let you rise up, and
that his cock had, only "minutes before I walked in", forced himself inside
you.  Did I believe that?  Only days later did I wonder why your cunt was
leaking spunk that evening if he had only managed to get his cock inside
you for a few minutes.

   The whole story though, as a package, had sounded completely feasible
and I accepted it in the manner it was delivered: Horny cunt, fucked that
morning, spunk still dribbling out of cunt down thighs later in day; on
knees looking for pen; no knickers, hot wet cunt; gets fucked.  Sounded
feasible enough so I gave you the benefit of the doubt.  I even let you sit
on my cock that night, after you had washed.  I wouldn't allow you to move
on my cock, but I did allow you to squeeze me until I filled your cunt.

   So, there I was today; watching you.  You on your knees with the dog
fucking you madly, your huge tits were swaying and bouncing with each doggy
thrust.  You looked up briefly and then hung your head (was that shame?).
But you didn't stop our dog fucking you did you?

   I could see you were going to cum.  I could see the blush rising from
your big tits to your shoulders and then your throat and to the lower half
of your face.  You were groaning, grunting even, as the dog's big cock
pummelled your cunt.

   Even as I watched the dog fucking you I knew there were going have to be
changes in the household.  I saw the emotion and desire on your face as the
dog's big cock thrust in and out of your soaking wet cunt.  I saw the
elation as his knot expanded well inside your cunt lips so you couldn't
escape before he delivered his spunk deep inside you.

   I watched him spunk inside you.  That last thrust as he pushed his cock
as far as he could inside his bitch's cunt as he tied to you.  I could see
that you were cumming the whole time.  I could see that your juices were
running down your thighs, and would soon be joined by the cum of the Great
Dane as he filled your needy cunt with his spunk.

   You looked up at me; as if seeking guidance.  I don't know, but I wanted
you to know that you were under my control as much as I needed to be for
myself.  While we were waiting for his knot to subside I told you to grab
the dog's cock as it slid out of your wet cunt.  I told you it must be
cleaned so the dog would think you were in control (twisted mind or what?).
I made you lick it from ball to tip and swallow it so that you had all the
joint fluids in your mouth.  I wasn't finished; I made you stay on your
knees and scoop the dog's spunk out of your cunt, rub it around your
vagina. Standing behind you I had a perfect view of your gaping cunt as you
collected the doggy sperm from it.  I'm sure you enjoyed it.

   When you had finished and stood up in front of me I told you that you
weren't allowed to wash yourself until I told you that you could.  As I
left for work I could still see spunk leaking from your gaping cunt and
running down your wet thighs.

   When I came home from work that evening you had dinner virtually ready.
There was no talk of fucking dogs, although I could smell the spunk that
had dried on your cunt as you stood at the sink in your tee shirt, your
arse bare as usual, and your big tits straining to escape the control of
the cloth.

   When we went to bed together I allowed you to sit on my cock and bounce
up and down until we both came, but you weren't allowed to shower, before
or after.

   In the morning you were still horny, but you needed to pee.  I laid
there stroking my cock to maintain my early morning erection.  You came
back to bed smiling.  You sat on me and kissed me before reaching between
your legs and positioning my cock directly underneath your cunt.  As my
cock slipped into your soaking vagina I kissed you deeply, playing my
tongue across your lips.  I held you still on my cock.  You were frantic,
but I wouldn't let you fuck me.  After a couple of minutes trying to bounce
on me you just collapsed onto my chest and begged me to fill your cunt.  I
turned you over and rammed my cock into you, just like a dog would.  I
could hear you gasping as I rammed against your clitoris, you came within
minutes.  I slowed down and teased you with long slow strokes until you
were begging me to fuck you hard.  I didn't, I made you squeeze your cunt
muscles rhythmically until you made me cum, I filled it with my spunk. 
When I came you were still so hot; I made you turn on to your back, and I
told you to slide your fingers deep inside yourself and spread my spunk all
over your vagina.  You eagerly spread my mess all over your vagina, labia
and pubic mound.  Then I made you rub your clitoris until you came.

   Spunk; you'd had loads of spunk in your cunt since yesterday and more
today.  You were pretty perplexed when I wouldn't let you wash your cunt
again or get in the shower.  I reminded you that you once went for a whole
week without a shower earlier on in our relationship when you worked at the
bank, and at that time I hadn't allowed you to sit down on the toilet
either.  Needless to say you soon complied; you wore a "normal" (for your
anyway) mini-dress for work and I was delighted to be able to smell the
sexy aroma of vagina and spunk arising from your cunt as you got out of the
car at the station to get the train into the city.
