   My wife was in hospital after just having our first baby.  I stayed with
her until she fell asleep and then made my way home.  I was horny as usual
and phoned my mistress (calling her Emily) to arrange to pick her up on the
way.  Emily and I had been having an affair for a few years and used any
opportunity to get together for sex.

   Emily is my age and we met while attending night classes at college. 
She has remained unmarried, why I don't know since she is a vivacious
beauty who is smart, has her own boutique business in a mall and dresses to
the nines.  She latched onto me about a week after I became engaged to my
wife, Doris.  I didn't want to breakup with Doris but I also didn't want to
stop seeing Emily either.

   She had a certain charm and personality that meshed with mine so we
continued to see each other at college and after.  I collected Emily and
drove to my house where we immediately retired to the bedroom for a fucking
session.  It wasn't long before we were naked and enjoying each others
bodies.

   I love panty swapping so I had Emily wear a pink cotton panties
belonging to my wife.  (I love fucking a woman while she is wearing another
woman's panties).

   All was going great for a while, we were having our usual amazing (ten
times better than the wife) sex.  I was on top in the missionary position.
Emily was gasping and groaning underneath me; her fingers were dug into my
ass plunging me deep inside her as she pleasured herself on my prick.  I
knew she was about to cum and I was more than ready to join her.

   Emily's body began to shudder and she soon began her usual gasping with
"fuck me, I'm your whore" dirty talk.  I replied calling her a "slut and a
Bitch" for fucking her friend's husband while she was wearing her friend's
knickers.

   The dirty talk pushed us to the edge and brought a loud gasp of pleasure
from Emily.  I knew she was "on the brink" as I felt her pussy clamp onto
my prick.  I felt my own raw lust build up and I was ready to shoot my
load. I stroked faster and then felt the wondrous sensation of my cum
shooting through my throbbing prick into Emily's pussy.

   Emily's orgasm was almost instantaneous.  She jerked her hips towards me
and began to cry out loud coming hard and shuddering all over.

   All I could think about was shoving my cock into her wet, tight pussy
and filling it up with my cum.  I was well past the point of no return when
suddenly a light shone in from outside through the half open door.

   The room became illuminated in bright light.  My immediate thought was
"my wife has come home".  I watched in horror as the door fully opened and,
as if in slow motion I saw, not my wife, but my wife's older sister poke
her head inside.  I could only stare at her as her expression changed from
mildly curious to bad surprise and then just pure raw horror.

   The sight that greeted her was one of confusion and naked bodies.  The
bed covers had long been kicked off so we were fully exposed when that
light came on.  I was desperately trying to withdraw from Emily's pussy
even as my prick was still ejaculating my load.  Emily was in the process
of screaming out her first loud "ahhhhhhhhhhhh" while turning her head
towards the door to see our unexpected visitor.

   My brain felt on fire as contradicting commands were issued that my body
and dick were in no position to carry out.  I just could not stop coming.
Emily was looking towards Mary but her gasping continued and I knew that
she was also having trouble in stopping.  She no longer screamed but
couldn't help whimpering quietly as her body continued to orgasm

   Pulling out my dick at that point wasn't a very good idea.  I should
probably have stayed inside her until I had finished.  As it is I finally
withdrew my still pumping and throbbing cock only to make matters worse by
involuntary ejaculating the remainder of my cum into the air.  I tried to
stop it with my hand but I think that made things worse.

   I looked at Mary; her expression was showing pure and utter disgust. 
Her face was deathly white and she looked close to fainting.  I saw her
start to gag and then she suddenly turned and left.

   I heard her run to the bathroom where she proceeded to be sick.  Emily
and I got dressed quickly and made our way to the car.  Even as we crept
down the stairs we could hear Mary retching in the bathroom.  I drove Emily
home.  We were both pretty shaken and wondered what Mary would do after
catching us.

   I arrived back home about a half hour later.  The house was quiet with
no lights on so I made my way to bed.  The next morning I was woken by the
sounds of conversation.  I immediately recognized the voice of my
mother-in-law speaking to Mary.  I guessed by now that they had arrived a
day early.

   They had a key and must have let themselves in the previous night and
went straight to bed in the guest room.  Mary must have been awakened by
the noise of us having sex and came in to check things out.

   I showered and eventually made my way down to join them.  My
mother-in-law was her usual cheery self so I guessed that Mary hadn't told
her anything.  Mary herself was like a different person, whereas normally,
she would be chatty and outgoing, now she was withdrawn and sullen.  Her
body language screamed, "stay away from me you sick fuck".  She barely
spoke to me during breakfast and I'm sure my M-I-L was suspicious.

   After breakfast, I drove them to the hospital for a visit.  The visit
was pretty uncomfortable so I made an excuse and left.  When I returned
later, my wife was alone.

   She told me that Mary wasn't feeling well so they had returned home
early, deciding not to stay the second night.  My wife was pretty pissed at
them for leaving early and blamed it on Mary saying she was jealous because
she had been trying without success to have kids herself.

   I stayed at the hospital until she fell asleep and then left to call
Emily.  I picked Emily up on my way home.  My wife would be home the
following day so we wanted to make the most of the night.  This time we
checked all the rooms and put a lock on the front door before we hit the
bed.

   Once we settled down we spoke about what had happened.  Emily said that
she found getting caught was extremely erotic and it made her really horny
just thinking about it.  She said that at first, when she had seen Mary she
had almost had a heart attack.

   She had felt extremely embarrassed to be caught naked on her sister's
bed.  But after I dropped her home, she began to relax.  She thought back
to what had just happened and she felt herself getting wet.  She said the
memory of Mary standing there, watching her being fucked was a massive turn
on.

   She had gone straight to bed (still wearing my wife's undies) and
masturbated herself to sleep while remembering how she had just orgasmed in
front of my wife's sister.

   That night the sex was incredible as we both gorged ourselves on each
other's bodies along with the memory of my sister-in-law watching us.

   Chapter 2

   This incident happened a few years ago.  As far as I know Mary has never
told anyone in the family.  She is still quite sullen in my presence and we
rarely speak.  This isn't an issue for me as we live in different counties
so rarely see each other.  It isn't the only time that I was almost caught
cheating but it is one of the more memorable.

   A few weeks later after my wife, Beverly, and baby John came home she
was talking with Mary on the phone.  I couldn't hear the conversation but I
feared the worst.  I puttered around in the garage straightening up some
tools and put up some shelves near the washing machine.

   "Doug I just had a lovely conversation with Mary." Bev said.  "She and
Mark are going to see a fertility specialist since she can't seem to get
pregnant.  She wants a baby so badly and feels like she is inadequate as a
wife especially since her baby sister has a baby and it happened pretty
fast."

   Bev got pregnant within 6 months of our marriage having tossed the birth
control pills the month we were married.  I smiled as she told me about
Mary's inability to have kids.  I decided that Barry, Mary's husband, whom
I liked might like to spend some time fishing or hunting with me.  I knew
he hadn't been in a while and deer season was coming.

   I called him and invited him.  He quickly accepted telling me he had to
get away from Mary for a while.  She was being difficult to live with
especially after visiting her sister in the hospital.  I pretended to not
know anything as to why but I knew it was because I was cheating on Bev.

   We made plans for hunting and we each got our licenses and tags for a
buck each.  In our town there is a butcher who maintains a freezer locker
plant and rents space for those who don't have large freezers.  He also
butchers deer for hunters.

   Mary came to visit Bev often.  She loved baby John and was a wonderful
aunt to him.  She let Bev shop or just get away while she babysat.  She
even bathed him and played with him.  He adored being spoiled by her.  I
knew she would be a wonderful mom and it was too bad she was unable to get
pregnant.

   When hunting season opened, Barry and I scouted some locations that were
public land in our area and discovered some trails and bedding areas for
deer.  We chose a couple of sites and put our marks on trees and the hung
our portable deer stands trimming away branches for clear shooting lanes. I
even put out two cameras to see what I might have an opportunity to hunt.

   It was during one of our scouting trips that he told me that when he was
a little boy he got a disease that rendered him with a low sperm count.  He
suspected that it was affecting his marriage even though he and Mary had a
wonderful sex life.  I humored him and made some remark that maybe I could
help out in that regard.  "My fertility is proved," I said jokingly.

   "That's true Mark but how could we get Mary to go along?" he asked.

   We had several ideas but my mind kept going back to that time she had
caught me with my mistress while Bev was delivering our first born.

   Nothing more was said on that subject for a month or so until one day
Mary was visiting and I came home from work.  "Hi Mary," I said as I put my
coat on the hook.

   "Hi Mark, Bev's shopping and she said she would be home about 7.  Johnny
and I have been having some fun.  He just woke up from his nap." She said.

   "Has he had his bath yet?" I asked.

   "No, I was just getting ready to do that.  Do you want to help?"

   "Sure.  I love giving him his bath.  I love the way he kicks and laughs
when I tickle and blow kisses on him."

   "Yeah, I like that too." She added.

   I was sort of surprised at her outgoing manner towards me.  She had
seemed sickened the time she caught me with Emily.  Maybe she got over
that. I thought.

   We bathed Johnny and he spouted off once hitting her in the face and
wetting her shirt.  She just took it off and continued as if nothing
happened.  I was surprised since she always made sure she didn't show any
of her body to me or in public.

   After his bath she confided in me that Barry couldn't seem to make her
pregnant and it depressed her.  She said she really loved him and wanted to
give him a child but they couldn't afford the procedure to get her
pregnant.

   About that time Beverly returned from shopping and I helped carry in the
groceries and bags.  Dinner was a roasted chicken from the grocery and with
a veggie and baked potatoes we all sat and enjoyed dinner.  It was during
dinner that Mary said, "Bev, I was talking with Mark here before you came
home.  I told him about Barry's low sperm count and that we couldn't afford
the in vitro fertilization procedure.  You and I have talked before about
this and you agreed that if Mark was agreeable then he could provide the
sperm to impregnate me." She said.

   I nearly swallowed my tongue and choked when I heard this.  Here I
thought she was disgusted with me for cheating on her sister and now... she
wanted me to impregnate her?  It seemed too good to be true.

   Bev said, "Mary I already told you that it was OK with me and that I
love him very much.  I don't consider it cheating if he impregnates you as
long as you don't steal him away from me." <laughing>

   "Mark, what do you say?  Do you... Will you help me out?  I promise not
to steal you away from Beverly.  You know I love you like a brother anyway.

   "What would Barry say?" I asked.

   "Oh we have already talked about this and he is fine with it.  In fact
he said that if our baby looks, acts like Johnny he would be very happy. 
He loves you like a brother anyway."

   We had more discussion and finally it was agreed that I would donate my
sperm to my sister-in-law.  The only matter was how and when since Beverly
wanted another baby soon anyway, a girl she hoped.  Bev and she discussed
it and decided that their next cycle would be the best time since their
cycles were about a week apart.  Plans were made for Mary to take a week
off from work.  She teaches at a private school.

   I had to plan vacation time too but that was no problem.  We set a date
that would ensure the timing was correct and I made reservations at a
distant hotel where we weren't known.  I used an old credit card to hold
the room since Bev didn't know about it and it was empty anyway.  I keep
two cards for that purpose.  I would pay cash on check-in.

   Beverly and I have a very active, adventuresome sex life.  She now
insisted that we not engage in sex until I get with her sister.  I was
going to be disappointed in not being able to sink my cock into my wife
nightly as I had done since we got married.  The most we ever abstained was
when she was in her period, then we did anal, or the month we waited after
Johnny was born.

   She kept me on edge every day though, telling me all sorts of things
about her sister.  Every day I learned something new even to her favorite
positions and where her most erogenous zones are.  The more she told me
about Mary the more anxious I got and the more I wanted her.  It reflected
in our own lovemaking too.  She suddenly insisted that instead of just
being trimmed short we would now shave each other since it is more personal
and appealing.  Bev got my beard trimmer, I have a short beard and
mustache, and trimmed be close.  Then she took my Fusion razor and put a
new blade in it and using the ultra-sensitive gel lathered me up.

   She grasped my very hard cock and held it variously to shave my entire
pubic area and shaft.  She gingerly shaved my sac and anus, cheeks too. 
After she rinsed me she applied her favorite vitamin E cream to the shaved
area.  It was soothing and felt wonderful.

   It was my turn now.  "WAAAAAAA" Johhny cried.

   "I have to go to him and change him, honey... be right back." She said.

   A few minutes later she returned.  I could see that he had nursed since
one breast was sagging a bit.  "Did he drain you?  I asked.

   "No, you can drain it and the other one when you finish shaving me." She
answered.

   I had a microwaved flannel washcloth that was steamy hot.  I put that on
her pussy area covering all the hair she had there.  She winced when the
heat touched her but left it lay.  I leaned up and kissed a nipple then
began sucking and draining her breast.  I love doing this for her.  It
brings her off and puts her in an amorous mood.  She orgasms easily when I
do it a certain way.  As I suckled I played with her hot pussy.

   Sensing her hair was soft now, I removed the cloth and applied the gel
to her entire pubic region.  I could easily get her to orgasm this way but
I had plans for her later.  I used the same razor she used on me since it
was still good.  I gently stroked away every little hair humming all the
time.  I knew I would be licking her bare skin soon.

   After rinsing her thoroughly I put her lotion on her as she had done me.
Then I continued kissing her and suckling her breast dry.  She was totally
relaxed now as I kissed my way down to her clit.  One lap and she orgasmed
loudly.  Since I couldn't have sex with her until after my week with her
sister, I rolled over and fell asleep.

   Everyday I became more anxious to be with her sister.  I had decided I
would make it like a date and woo her and dine her.  We would have some
wine or wine coolers but nothing heavy.  I abstained from beer too.  I made
a trip to the barbershop and got a haircut and had them trim my beard
professionally.  I even had a manicure and clear nail polish applied.  I
have a goodly amount of chest hair, unlike Barry who is almost bare.  I
decided I would keep that and see how she reacted to it.

   Finally the day came for our `vacation'.  She met me at the front door
just after Barry left for work.  I trundled her suitcase to the rented car
and we were off.  I buckled her into her seat and kissed her using a little
tongue.  She tasted wonderful.

   We chatted along the way.  She kept asking all sorts of questions about
where we were going, what we were going to do and all of that.  I kept her
in the dark on some things since I wanted her to be mine for this week. 
She did confide in me that Barry and she had fucked most of the night and
he deposited several loads in her.  She was wearing a diaphragm to keep it
inside her hoping that his sperm might find her fertile egg.  She was due
to ovulate in a couple of days anyway.

   I wouldn't mind having sloppy seconds knowing that my sperm is virile
and proven.  After our two-hour drive we checked into the hotel.  I had
asked for a suite and was treated to a three room suite with an oversize
bathroom and a Jaccuzzi with appropriate additives.  The suite looked out
over the landscape with rolling hills and farmland.  It face west so we
would have a lovely sunset viewing.

   Upon entering the room she found a lovely bouquet of yellow roses and
large daisies along with baby-breath filler.  There was a card attached. 
It read: `To my lovely, beautiful sister whom I have loved since meeting.
May this adventure be a new love for both and may you be fruitful.  I will
do my part so you can multiply.  Love, Mark.'

   I saw tears in her eyes as she read the card.  She came into my arms and
kissed me like a passionate lover.  "I'm sorry about my attitude with you
and your mistress.  I promise not to be jealous.  I want to us to be lovers
for life, brother." She said lovingly

   "I would love nothing more.  Now, I suggest we change out of our travel
clothes into something a bit more casual as I have plans for the rest of
the day.  Put on some shorts and a top.  I hope you don't wear a bra or
panties for the rest of the week." I told her.

   "Mmmmmmm... A man after my own heart.  I bet you don't wear undies
either."

   "Nope.  I've not worn briefs since high school and I seldom wear any
with jeans.  Today, I am commando in my shorts too."

   She was not shy undressing in front of me.  For the first time I saw my
sister-in-law naked.  She puts Beverly to shame.  Her breasts are a full C
cup and with her flat tummy, a small waist and hips just made for birthing,
she was the perfect specimen of womanhood.

   My cock instantly hardened revealing to her my full 7 plus inches.  I am
circumsized with a flared helmet that is much wider than my shaft.  My
shaft does taper to a large base ensuring a tight fit in any channel.  She
grasped it and stroked it as she told me that it is much larger than
Barry's.  She loves his but she thinks mine is much nicer.  I didn't want
to shoot into space so I suggested we either get in the bed and do this
thing we came to do or dress and make this a romantic event, which is what
I had planned.

   "I think I like the romantic event idea," she said as she let loose of
my cock.

   I kissed her and we got dressed.  We left the hotel and walked the
nearby street looking into various shops and boutiques.  There was no rhyme
or reason since we were enjoying each other's company and holding hands. 
Passersby took note of our dress since it was a workday and we were
obviously not wearing work clothes.  She had on a pair of white mid thigh
shorts with a girly tank top.  Her breasts were obviously unencumbered as
they were bouncy and free moving.  She was completely covered but there was
no doubt she was braless.  Also there was no panty line so she must have
been wearing a thong or sans panty.

   We both loved the attention we were getting.  My shorts were on the
small side and my package was semi-hard and showing under my light blue
bermuda's.  After about an hour of walking I found the cozy little Italian
place I had made reservations at and we went in and shown to our table.  A
strolling violinist played some wonderful love music.  I tipped him
lavishly.  A waiter in a tux with tails appeared with a bottle of wine.  It
was properly chilled and had an excellent bouquet.  I tasted and approved.
He poured each of us a glass and took our order for appetizers.

   Dinner was wonderful.  We enjoyed a Veal Parmesan over pasta and more
wine.  We continued to chat and I learned so much about her that I never
knew before.  She told me how she so much wanted a boy first and that she
had studied all of the information medically known from the internet and
Planned Parenthood that when she found out her husband was basically
infertile she was devastated.  "When I saw you with your mistress that day,
I was really sick.  How could you treat my sister that way?  I asked
myself," she said.  "I was physically sick and right then I didn't want any
more to do with you.  It was days later that I woke up in the middle of the
night.  I was sweating profusely and my pussy was soaked.  I must have had
a hell of a wet dream.  I remembered then, I saw you making love... really
making love to her.  She was not just a fuck to you.  She was someone you
cared deeply about.  I remembered seeing your cock, long and thick gushing
your sperm all over her.  I lay there thinking to myself, `how can I get
him in my bed?  Get me pregnant?  Make love to me like he did her." She
went on.

   I was holding her hand as she told me this.  I knew she and I would be
long term lovers and this would be a life-long event and she now wanted
this more than anything.  The waiter brought the check and I paid, leaving
a generous tip.  We left hand-in-hand back to our love nest in the hotel.

   As we arrived, a bellman came and gave me a card.  It was a gift card to
an adult store just across town.  He assumed we were newly-weds and trying
to be incognito.  I gave him a tenner and thanked him then we went to our
suite.  We wasted no time leaving our shoes and clothes at the door.  She
beat me to the bed, but just barely.  She threw off the spread and blanket
leaving only the top sheet.  She sprawled face-up and spread-eagled in the
middle of that king-sized bed.

   I saw she was bare just like Beverly and I wasted no time falling on top
of her.  Our lips met in a frenzy of passion and groping.  My hands were
all over her breasts and at times around her neck as I overwhelmed her with
passionate kissing.  It wasn't long that I was suck kissing her neck
leaving my love bites all over her.  I never gave any thought to what the
appearances would be in a couple of days as a result.

   She was just as passionate as I.  She locked her legs over mine and kept
trying to get my now hard cock inside her baby channel to do the task we
were here to do.  I decided as we were locked in our passionate embrace
that lovemaking was out.  This was time for babymaking and baby make we
would do.

   I reached for her pussy with my free hand as I gently raised up my body
from hers.  She found my hardness and guided it home.  It was mutually
accepted at that moment.  She raised her hip just as I slammed my hips down
to try and massage that nub.  She was clinging to me, her fingernails
clutching my back.  She hadn't trimmed hers short.  They hurt as she
hunched up to me.  My hips were now in frenetic motion as I screwed her. 
My extreme thickness at my cock's base combined with my pubic bone
attacking her clit put her over the edge.

   "AhhhhHHHH ... OOOOHHHHHHH..." she sceamed in my ear as her first orgasm
came over her.

   "Hmmmph" "Hmmmph" "Hmmmph" "Hmmmph" "Hmmmph" our bodies sounded as we
came together in fluid motion.  My cock was driving against her cervix.  I
couldn't hold out any longer.  "ARRRRGH" "ARRRRGH" "ARRRRGH" I groaned as
my cock swelled with the passage of my semen through my cock tube.  I
slammed her into the bed hard.  My cock spewed forth my seed in hot jets
bathing her cervix and even shooting into her cervix.

   She screamed back at me with her moans of pleasure and words of love as
our lust and passion overwhelmed us.  I was now on autopilot.  My body was
responding only to nature's call to procreate and deliver my love seed into
my lover's welcoming cunt.  She had her legs locked around my legs
squeezing me and not letting go.

   Fifteen minutes is not a long time, generally, but lovemaking or
babymaking like we were doing, fifteen minutes is a long, long time to be
locked in a passionate embrace with a long hard cock fully seated in a hot
steamy pussy.  I could feel her velvetly walls clinging, clasping and
releasing as though massaging my cock, a feeling felt only in rare
situations.  There was no doubt her body was accepting my offering to her.

   I collapsed on top of her.  I was totally exhausted, dead weight lying
on her heavily breathing as my cock continued to involuntarily flex and
flip and shake and squirt the last few drops of my sperm inside her.  She
must have passed out too as she just lay there, her arms were now relaxed
though still around me.  It was as if she would never let me go.

   We awoke a few minutes later.  My cock was wilted and beginning to slip
out of her.  I was aware at that moment that I must be suffocating her.  I
rolled off of her but she just held onto me tighter and rolled with me.  My
cock slipped out of her pussy and fell to the sheets.

   She locked onto my lips with hers and peck kissed me a hundred times at
least.  I returned each and every one similarly.  I now lay on my back and
she over me.  I was too exhausted, sexually overworked to continue being
the lover I wanted to be.  She lay on me now holding my pussy soaked cock
trying to coax life back into it.

   "Honey, that was the best I ever had.  I've never come so much in my
entire life." She whispered to me.  "Rest now my love.  Take a nap.  This
night is young and this cock is mine for the next week." She continued.

   I fell asleep with her on top of me.  Our week of baby making and loving
was certainly fruitful.  Every day at least twice a day we joined in
matrimonial fashion to breed her.  It was a never-to-be-forgotten week,
whatever the outcome.  I loved her as much as my own wife and I'm sure she
felt the same with me and Barry.

   We did something new an exciting each day after breakfast (brunch) that
would be memorable for us.

   As we drove slowly back to our homes we talked about the past week and
made plans to do something at least once a quarter with each other alone.
"Next time, we take pictures and video's just for us." She said.

   We were each welcomed by our spouse with loving kisses and our marital
bed awaited each of us with our real mates.  Beverly was her normal
passionate self and we made love vigorously twice that first night.  Johnny
slept through the night without crying.

   It was a month later that Beverly informed me she was pregnant and I
learned from Barry that Mary was expecting too.  Both families were
extremely happy.

   The End
