   "This sounds like fun Ed," my mother-in-law Lucy said.  "We can go up
Thursday night, get everything ready, and the kids can meet us up at the
cabin Friday evening."

   My name is Stuart.  Lucy and Ed are my soon-to-be in-laws.  I am 19
years old and am engaged to their daughter Janice who just graduated from
high school.  We have not been intimate yet but her parents, believing they
are modern thinking, don't know that.  It sounds backwards where usually
the kids have screwed around and the parents don't know it.  Janice and I
want to make that wedding night special.  To be honest if it wasn't just a
month away we probably couldn't make it.

   Janice and I were over visiting her parents, Lucy and Ed, talking about
spending the weekend at their cabin.  It was apparently a nice place up by
a lake.  The cabin really belongs to Lucy's parents but they don't live in
the area and Lucy uses it whenever she wants.

   "Honey, I've got a presentation Friday morning to the board," Ed
explained.  "We can't leave until Friday afternoon."

   "Can't you postpone it?" Lucy asked.  "I need all day Friday to get
things ready.  We haven't been to the cabin in a couple years."

   "Wish I could cancel," Ed replied.  "But it's the board meeting.  They
don't postpone those things."

   "I could take you," I suggested.  "Janice has to work Friday too so she
could come up with Ed Friday evening.  I'm off Friday so you and I could go
up Thursday.  I could help with the clean up so it won't take as long and
you could actually get a little rest before everyone gets there."

   Lucy looked at Ed and Janice for approval.  They nodded OK.  "Great,"
Lucy exclaimed.  "Thanks Stuart.  I'll see you Thursday after work."

   As it turned out I was able to get off Thursday afternoon so we got a
head start on things.  I picked up Lucy and a boat load of stuff that she
wanted to take up.  My SUV was packed full.  Our road trip was actually a
lot of fun.  I drove and mostly listened as Lucy talked nearly non-stop. 
She talked about how she had gotten pregnant with Janice as a senior in
high school, apparently up at this cabin we were heading to.  She and Ed
married right after graduation and a month later Janice was born.

   It didn't take much for me to realize Lucy was 36.  I started glancing
at her more, really looking at her features.  Well I did so as best I could
and still drive safely.  She was really quite stunning.  The traditional
blond hair, short even though Janice's was long.  Lucy had blue eyes and a
great smile.  I liked it when she laughed.  Looking a bit lower she had
well shaped and from my angle of view, nice sized breasts.  Lucy was about
5 foot 8 inches, a couple inches taller than her daughter Janice.  Ed
wasn't any taller than Lucy though.

   Occasionally Lucy would ask me questions, initially about my family and
younger years.  Then she moved to my future plans and eventually tried to
pry out information about my relationship with Janice.  I kept mum on that
last subject as best I could, just that I loved her daughter.

   Two hours later we arrived at their cabin, nestled up to the side of a
lake like they said.  Looking along the water's edge I could see one cabin
after another, not too close to each other, but close enough to wave to a
neighbor if you saw them.

   We quickly unloaded the SUV and began putting away all the goods.  Lucy
and I were still having a lot of fun, joking around.  We got everything put
away and then began just cleaning up the cabin.  I vacuumed while Lucy
dusted everything.

   Suddenly I felt, and heard, a snap to my butt.  "Ow," I yelled.  "What
was that for?" Lucy had taken her dust cloth, rolled it up and snapped my
butt with it.

   "You're too quiet," she said laughing.  "You haven't said anything for
at least 5 minutes."

   "Well you're going to get it," I told her.  "You'll never know when I'll
strike."

   "Oh, is that a threat?" she asked.

   "No threat, just fact," I promised laughing.

   We finished what we were doing and then just sat around talking for what
seemed like hours, Lucy still trying to get more personal information out
of me.  Finally Lucy suggested, "Let's go take a quick swim in the lake."

   "Sounds great," I said.

   As we walked to the water I was behind her and couldn't help but notice
how nice her ass looked in her two piece.  I wondered if maybe I should
have worn a pair of underpants with my swimsuit to help hold in my sudden
hardening shaft.  I couldn't wait to get in the water to hide my
embarrassment.

   Though it was about 10 at night, the temperature was still over 80
degrees.  The water was a little cool but I didn't mind as it helped keep
my shaft nice and small.

   Lucy and I splashed around, dunking each other.  It meant that we had
our hands on each other more than I thought we probably should.  Lucy had a
nice body and it made me wish Janice was here so that I could hold her
close.  I was starting to get a little bit aroused being here alone with
Lucy.

   "Take this," Lucy yelled as she dunked me a good one.  She swam away
from me towards the shore as I did my best to catch her.

   "You're going to get it now," I warned her, getting closer every second.

   But she reached the shore before me and raced up the short beach to the
cabin with me close behind.  I caught up with her in the living room, both
of us dripping wet.  I decided to just tickle her, not knowing at the time
that she was extremely ticklish.

   "No, no, not that," she screamed trying to get away.  Then she turned
the tables on me and began to tickle me back.

   I wiggle around and was able to get away.  She grabbed at me and caught
the back of my trunks.  With Lucy holding on tight I literally yanked my
own trunks down to my knees before falling forward onto the floor, tripped
up by my own trunks around my ankles.  I don't know what got into Lucy but
she started laughing and just yanked my trunks the rest of the way off.

   "You little brat," I yelled looking back at her.  I was on my stomach on
the floor.  She was standing behind me with my trunks in her right hand and
her other hand covering her mouth.  She looked like she was in shock at
what just happened yet still laughing at the same time.

   Not caring that I was now nude, I wanted to get back at her.  I couldn't
let her get away with this.  I got up and lunged for her.  She gasped as
she looked my naked form.  She threw my swim trunks at me, turned and ran.
But she only got a couple of steps before I grabbed her own trunks.  She
couldn't move forward anymore and I did what she did to me.

   "You deserve this," I told her as I yanked her trunks to the floor.  At
this point we were both standing up.  I began to tickle her some more.  I
couldn't really see much of her groin area other than to notice that she
was quite hairy.  I guess she didn't shave much except around the edges of
where her swimsuit would show any growth.

   She stumbled on her trunks that were around her ankles, trying to get
away.  The next moment she was on the floor and I was kneeling next to her
tickling her without mercy.

   We wrestled around and I finally pinned her on her back with my body on
top of hers.  My position though wasn't that I was straddling her.  No, I
was actually kneeling between her legs, my knees up under her legs, with my
body leaning forward mostly on her torso to help keep her down.

   The next few moments were sort of a blur.  With our bodies the way they
were and her trying to squirm forward out of my grasp, I kept moving
forward with her, still tickling her.  Honestly, I wasn't thinking of this
as anything sexual.  So I don't remember getting hard so my cock must have
gotten that way on its own.

   As I reached up with my hands to hold down her shoulders I brought my
lower section upwards to get more weight on her, to keep her from getting
away.  Somehow my cock pressed up against her pussy and the head of it just
slipped in.  Suddenly we both froze, the head of my cock still inside of
her.  "Oh God I'm sorry," I said as I quickly pulled out.

   Lucy smiled and took advantage of my momentary weakness.  She pushed me
sideways on to my back and rolled over on top of me, tickling me as she
went.  I was still in shock at what I had done so didn't put up much of a
fight.

   She was now straddling me, her hands on my shoulders, her face down
close to mine.  Then I felt it, Lucy's pussy hair.  I felt the pressure of
her body against the head of my still hard cock.  The next moment she was
sliding her body down onto me.  She paused a moment and then all the way
down.  I was completely inside of her.  She slowly pulled her body up
nearly off of me and down again.  She whispered into my ear, "Is this what
you were trying to do to me, you naughty little boy?" I just laid there
speechless.

   Lucy began a steady slow rhythm as she quietly fucked me.  What Lucy
didn't know at the time was that I was a virgin up until then.  She became
my first and only sexual partner.

   Gradually Lucy increased the speed and forcefulness of our mating.  I
found myself beginning to thrust upwards as she came down on me.  Within a
minute Lucy was groaning out loud and pounding me hard when she suddenly
stopped.  I was completely inside of her as she sat up, arched herself
backwards and yelled out, "I'm cumming."

   I watched her for about ten seconds and then it happened.  My body
reacted and I climaxed, shooting my cum deep inside of her.

   She looked down at me and cried, "No, don't cum in me."

   But it was too late.  I had my hands on her waist and was holding her
tight down on me as I continued to shoot my cum up in her.

   "Oh shit, no," she cried again as she managed to get off of me.  "I'm in
my fertile stage.  Fuck Stuart.  Oh fuck oh fuck, what have you done?"

   She got up off of me and ran to the bathroom.  I heard the shower going
and I followed her there.  Her bikini top was on the floor.  I pulled the
curtain aside and stepped into the shower.

   "No, you can't," she cried.  "We can't.  I can't get pregnant by you.  I
mean it will ruin everything."

   I heard her but I wasn't paying attention.  I couldn't take my eyes off
of her beautiful breasts.  I put a hand on one as I put my other hand to
her back pulling her to me.

   "No please, we can't do this," she said.

   I quieted her by pressing my lips to hers.  She melted in my embrace,
moaning into my mouth.  We kissed like lovers do, with an urgency and
passion of two souls reuniting.  I knew I was hard again already.

   Pressing her back against the side of the shower I stepped between her
legs.  My hard cock quickly found its mark and I was inside of her again.

   "No, we can't," she pleaded as I began to fuck my future mother-in-law.
But she gave no other resistance.  I fucked her for several minutes before
she had another orgasm.  But I wasn't near ready, having just recently
climaxed myself.

   While she was still climaxing I pulled out, turned her around, and
re-entered her from behind.  I saw it done in a movie once and always
wanted to try it.  As I began fucking Lucy again she cried out, "Oh God."

   I fucked this beautiful woman through two more orgasms before filling
her once more with my seed during her last orgasm.

   We finally got out of the shower and got dried off.  She led me to her
bedroom, took me to her bed.  "I don't know what I'm going to say if you
get me pregnant.  I'll just have to have a secret abortion or something. 
My husband can never know.  But if you don't mind, can you use a condom
from now on please?"

   "Sure," I agreed.  "Do you think you have enough to get us through the
weekend?"

   Lucy laughed.  "Let's just see how well you do in my bed tonight."

   We kissed like two high school teenagers but I couldn't get what she
said out of my head.  Lucy was fertile right now.  I actually could get her
pregnant.  Her warning was like an invitation to me, a challenge to be
conquered.  As much as Lucy tried to get me to use a condom, they always
seemed to slip off just before I climaxed.  I wonder how that happened.  I
guess the sex was just too good for Lucy to worry too much about it.

   Lucy and I didn't get the rest I predicted.  When we weren't fucking we
were just holding each other and talking.  I finally shared with her that
she was my first.  She shared with me that she and Ed hadn't been intimate
for a few years, quite a few.  What was interesting were the stories she
told of how she satisfied that need, something for me to write about at a
later time perhaps.

   What is important to know is that as the night went on it became
increasing clear to me that I was falling head over heals for Lucy, my
future mother-in-law.  We talked about our future, when Janice and I get
married.  She shared how we couldn't ever do this again.  Then later, when
we were having sex, she made me swear we would never stop, no matter what,
even after I married her daughter.  That was one promise I quickly made and
meant it.

   We did get a little bit of sleep but had fucked most of the night away.
By morning Lucy quit trying to have me wear a condom.  As the day wore on
we both realized that Ed and Janice would soon be arriving and we would
have to stop all this.

   "Promise me you won't do anything that will jeopardize all of our
relationships," she asked.  "Things have to go on as before.  Ed and Janice
can never know.  Promise me."

   Reluctantly I said, "I promise." But deep down I wanted this out in the
open.  I wanted Janice to know that I had fallen in love with her mother. I
wanted both Ed and Janice to know that I had fucked Lucy all night long. 
But I promised anyway.

   The End (until Janice and Ed show up)
