   Mother in law Part 1

   Religous fuckers can just evacuate right fucken now..





   I have been married to Sue for only two years, but I can say that I got
the short end of the stick.  Her mother Nancy is still young and vivacious.
At 43 she has a better body and personality than my wife and I have always
been sexually excited just being in her presence.  However I was never able
to act on these feelings as I was after all married to her only daughter
and they were a very religious family.

   When the mother in law has aged very very well, the same cannot be said
of Dick her husband.  He's the epitome of the old fart.  He is approaching
50 and looks and acts 70.  I often wondered what she saw in him, but she
still always doted over him like a newlywed wife and I could see that she
was very much in love with him.

   About 6 months ago, an occasion arose that found me alone in the mother
in laws house while she and my wife went shopping.  I tried not too, but
I've always been a bit of a voyeur and shortly after they left I was going
through her dresser drawers.  I was rock hard as I examined her panties and
bras.  I found myself sniffing the crotch of a pair of her used panties
from the wash basket in her room.  They were very sexy, with minor skid
marks on them.  You know you always think that your idols wouldn't have
skid marks but the truth is they all do.  As I drew the pungent smell into
my brain I couldn't help but wonder what her cunt must be like.  I could
picture it hard up against the crotch shield of the panties and got even
harder although I didn't think that would be possible.  I quickly freed my
erect cock and wiped the pre orgasmic cum of it into the crotch of her
panties.  I imagined that my cum was going into her cunt, soothing the fire
between her loins.

   I carefully placed the panties back in the hamper and continued looking
through her drawers.  I found a box of condoms which surprised me.  For
some reason I had thought that she was beyond worrying about pregnancy, but
obviously she was still very capable of conception.  Hidden beneath all her
underwear I found her diary.  I knew that this was something I shouldn't
read but I couldn't help myself.  I lay on her bed reading the dairy as I
stroked my cock.  It started off very innocently but then I found myself
studying each word closer as she began to talk about having an affair with
her boss at work.  I read the entire thing, my mother in laws sexuality was
enhanced to a totally forbidden level by the time I had finished.  It
seemed that my mother in law was getting relief from another. In fact she
had been having an affair with his boss for over a year.  According to the
dairy she had only yesterday allowed him to fuck her twice.  I also learnt
the reason for the condoms, while her husband had had a vasectomy, her
lover had not.  For this reason she always insisted her boss use a condom.
I was lost for words as I finished ready and masturbating.  I shot off and
quickly used some of her dirty underwear to wipe up.  Then carefully I
replaced the diary and left the room.  From the diary it was obvious that
her husband knew nothing of her adulterous liaisons.  Armed with this
knowledge I formulated my plan.

   It was several days later that I finally got to be alone with my mother
in law.  I just came right out and told her that I knew about her adultery
with her boss.  At first she didn't believe me until I mentioned some dates
and stuff and then she knew that she was caught.  She began to cry and
begged me not to tell her husband, telling me that she was planning on
stopping it anyway.  I don't know why I didn't feel any pity for her, I
just felt like a king with all that power over her and I relished it.  I
won't tell Dick if you allow me to fuck you whenever I want I said.  She
couldn't believe her ears.  What? ..  You are my daughter's husband.  I
can't do that she sobbed.  Fine I answered, then I guess that poor old Dick
as well as Sue will have to be told.  I made to leave and was surprised
that I got to the door before she stopped me.  OK she whimpered, but only
if you use a condom.  Not a problem I smiled.  I followed her as she slowly
led the way upstairs to her bedroom.

   She reached into the drawer and passed me a condom, I stripped at the
same time as she did, and rolled the condom over my cock.  Then my mother
in law lay before me on her back, her legs splayed wide and a look of hate
in her eyes.  Ok then, get it over with she snarled.  I just smiled and
moved to the foot of the bed.  Then stroking my cock I moved over her body.
Her eyes were closed in anticipation of this wicked event.  For some reason
I had expected her to participate more sexually in this coupling.  I moved
the head of my cock up and down her slit to try and get her into the mood.
She didn't open her eyes just snarled at me to finish it already.  I really
hated this bitch right now and quickly I pulled the condom off my cock and
dropped it unseen on the bed below her.  She yelled once more for me to
fuck her then, and I did, I rammed my cock in her so hard and so deep that
she gasped as the ferocity of the assault.  She snarled again and I began
to hump her as though I was possessed.  It didn't take long, I had been
dreaming of this since I first saw her.  In less than 2 minutes, I buried
my meat inside her and sent an enormous volley of sperm shooting deep into
her womb.  I humped her several more times to ensure it was in deep and
then pulled out.  At no time did she open her eyes.  Once my cock was out I
pulled on the unused rubber as if I was removing it and her eyes opened to
watch me as I flashed it down the toilet.  She didn't move, just looked at
me with hatred in her eyes as I dressed.  Before I left I made a gesture to
pat her pussy, (I was really wiping up some tell tale sperm that was
beginning to leak out) and she just yelled at me to fuck off.  I did.

   My wife is gonna have a sister or brother now in 6 months time.  I
managed to knock the mother in law up good.  Of course she had to tell her
husband about her relationship with her boss.  Everyone thinks he is the
father.  Hey she couldn't tell her daughter she was pregnant with her
husbands child could she.  I never did fuck her again but I can't want to
see how much her child looks like me.  It might have been once, but it was
an awesome fuck.  She has a great cunt.
