I am a happily married man married to the most
wonderful woman, but she has a sister that I have fantasised since the day I
met her.

My wife's sister is a bit of a prick tease, we get
on great and every time we are together, we always have a dirty laugh.

She sometimes stays over our house and when she
does, she slips into her PJ's and I know she is not wearing any underwear.

It gets me so hard knowing that and I can’t help
just looking at her pussy to see if I can see anything.

My wife and her usually have a girl’s moment, when
they do, I go into the guest room in which she is staying and go through her stuff
and find her worn sweet smelling panties. I simply can not help myself, I sniff
the sweet smell of her pussy on them and get so hard, I then pull my cock out
and rub it up and down them, imagining my cock sliding over her clit.

I grasp her panties fully around my cock and start
to wank myself of in them, the smell of her pussy scent heightens my arousement
and makes me pump faster and faster, the precum starts ozzing out of me onto
her panties and seeing it on them makes me loose it and I shoot a massive wad
of hot cum, soaking part of her panties. I slide the head of my hot spunky cock
all in it.

I then put the panties back and leave the room
with a big flushed grin, knowing she will be wearing them the next day, it just
makes me hard all over.

One day my dreams and fantasies of making love to
her came true.

It was the weekend, my wife was working and her
sister had asked me to come over if I got bored to give her a hand with the gardening.
Of course I said yes and went around an hour later.

When I arrived she had already begun doing some of
the gardening at the front garden. As I got out my car I said, "Typical woman,
can’t wait."

She just gave me a look and said, "I was
expecting you sooner, you took too long!" in a sarcastic but cheeky manner.

I said I was going to quickly get a drink and be
right out to help, as I walked past her, I gave her ass a nice firm slap on her
ass as I always do.

She only said, "Oi cheeky!" So I love it
knowing I can get away with it.

We then did the gardening for the next few hours
in the baking sun. When we finally finished we went inside the house and collapsed
on the sofa next to each other.

We were leaned up against one another and I moved
my head over to her and said to her jokingly, "You’re all sweaty and
smelly."

She elbowed me and said, "So are you Mr, your
still dripping" wiping her finger over my forehead. "That's man swet
baby, that’s my sexy smell!" laughing and doing a mascaling voice. She
replied with a uhu and leaned her head over laying it gently on my chest and
smelt me. "It's actually not bad" she said, "I told you, it's my
alluring smell, watch out, it may just take over you and I chased her around the house, knocking
things over she tried to get away, she ran upstairs where I manage to catch up
with her and she runs into her bedroom closing the door behind her. I manage to
stop it and push the door open, she steps back laughing and giggling, bending
over forwards from the laughter, her hands stretched out trying to stop me from
coming closer.

I slowly approach her with a sinister look and a
dirty grin, I said, "oh now you've done it, you’re in for it now! You've
got nowhere to run." She looked around wondering how to get out as I
approach her closer, I stick out my hands and our fingers slide between each
others. I push her back towards her bed as she tries to resist me, but she can’t
over-power me and she falls backwards onto the bed, I follow her down still
gripping her hands. I pin her down, her arms above her head and my legs spread
on either side of her. "Oh your done for now, your mine now missy, know
one can help you now, know one will hear you scream!" She replies still
chuckling with a sexy 'Ooh' and laughs more. "Ah you like that huh" I
said, she replied, "maybe baby" and sticks her tongue out at me.

"Ok that’s it, your mine" and as I say
that, I lean down as she still tries to resist me and bite her neck, my tongue
softly touches her sweet skin for a brief moment. She screams out and her
fingers tighten harder with mine. I pull back and said, "I warned you didn’t
I, but no, you was a bad girl, so I had too." She laughs and says,
"Yep, im a baaad girl, so what you gonna do about it!" Thoughts rushed
through my mind and my cock twitched hard. I shake my head at her and said,
"What am I gonna do about it huh, I think I'll just have to bite you more
this time!" Her neck leans over to the side which I bit, I lean in towards
it and then move to the other side quickly and take another big bite on her
neck, this time I started sucking and licking it, she let out a moan rather
than a scream and I continued for a few seconds. As I pulled away I licked up
her neck, just to be as cheeky as possible. I looked at her from above, her
eyes were closed and she was out of breath. She opened her eyes slowly and bit
her lip, "That was very naughty of you, but very nice!". "Oh
really?" I said, "I better bite some more then" and went down
again and this time licked her neck all over, biting in certain places.

"Stop stop!" she said. I pulled away,
"It's too much, I don’t think we should?" I apologised. "Sorry,
I didn't mean to over step, I just couldn't help myself, especially when you
moaned."

She blushed and smiled slightly, "I know, it
was too nice, you have an amazing touch, but your married... to my sister, it's
too risky."

I looked down sad knowing how close I had been to
fafiling my dream. She put her hand on my chin and turned it to her,
"What's wrong?" she said. "You are right, I am married and to
your sister." I sighed a depressive laugh, "But... oh god." I
said.

"What, tell me, please tell me!" Her
voice so sincere, it melts my heart.

"I'm.. I.. I’m in love with you." I
looked down and pulled back of completely, unsure as to what would be said.

There was silence, it seemed to last for ever and
then she spoke, "For how long?" her voice lowly asking.

"I covered my face with my hand, "Soon
after we first met. At first I thought it was just a typical boyish crush, but
after we got to know each other and time passed by, I realised that the
feelings hadn't gone, instead they had become even stronger and I found myself
looking at you all the time."

"God, you must think I’m a typical scum
bag?"

She turned and faced me, putting her hand on mine
softly, her eyes wide open, "No, I know you too well, I know you are not
like the other guys out there, your are a great guy. You look after me and sis
so well, at times I even feel like I’m your wife the way you treat and look
after me!"

"Really?" I laughed cautiously.

"Yes, really. If you were single I would
scoop you up in a second, that’s if I didn’t get beat to it first by all the
other girls."

"Now your just tryna make me feel
better."

"No I am not, you know, your not the only one
who has feelings for someone they shouldn't." I looked into her eyes in
amazement.

She put her head down, "It's true, I had a
crush for you when we first met, you was amazingly hot. I was so jealous of sis
and how on earth she managed to get someone like you.”

“Was huh?” I laughed. “Idiot, you know what I mean;
you are as gorgeous as ever.”

I smiled, “And… how do you feel about me now?”
Hesitantly I said.

She bit her lip and looked directly in my eyes, “I
don’t think I should answer that.”

My eyes opened wide. “Tell me...please” I asked.

“I still have feelings for you. Oh god” she covers
her face in embarrassment.

My heart missed a beat and I pulled her hands from
her face, she turned her head, but I turned it towards me...I stroked her hair
moving it from her face, then leaned down to her and softly kissed her on the
lips.

She let out a light moan and we then rubbed our
faces against each others. Our breaths were getting shorter as we both started
kissing each other softly, I was in heaven. As we kissed I whispered to her
that I love her...she kissed me more firmly holding me tighter...”I love you. I
love you so much”. I smiled and knew what that now was the moment, the moment I
had dreamed of for so long, she wanted me I wanted her and no one was there to
disturb us.

Our lips met and tongues started to slide around
each others, our bodies wiggled against each other’s and I began to slowly
grind her through our cloths.

My cock was rock hard and causing me some
discomfort from being trapped in my jeans. The feeling of my cock rubbing
against her was sending both of us over the edge. Our hands started to explore
each other’s bodies as our grinding became firmer and faster.

My fingers traced down her side and I began
lifting her top up, I pushed myself up and lifter the top just over her huge
double E breast. She was wearing a very sexy red bra and her breast clearly
were to big for this as part of the breasts were hanging out.

We looked at each other for a moment knowing what both
were about to commit to. We both nervously smiled at each other and I began to
lower myself down to her breasts where I began kissing on top of. She ran her
fingers through my hair as I began kissing and licking her, I lifted her bra
upwards to reveal these awesome tits, my cock twitched so hard and I just went
straight in and sucked the fuck out of them. She moaned out “oh god!” as my
tongue thrashed at her nipples hungrily. “God baby, eat them...there all yours”
she said. I ate those tits for a few minutes until I couldn’t take it anymore.

I leaned up and pulled of my top, she looked at my
chest and ran her fingers through my chest hair pinching my nipples and
giggling. “Oh your gonna get it now” I said...”Mmm I hope so, but what am I
gonna get huh?” She cheekily said.

“How about my hard cock inside you?” I replied.

“Mmm” and she bit her bottom lip, “Only if you
fill me up with cum!”

My mouth dropped, “You really want that” I asked
leaning down and kissing her neck. “Yes!” She whispered into my ear, “I want
your seed in me”

I was still shocked, usually the guy begs the girl
to do this, but she was encouraging it.

“Something could come from this if we do” I
said...”I know” she replied and “I want it to”

I stopped completely, totally forgetting the
moment of heat we were just in...”What are you saying? You want a baby with
me?”

She looked away from my puzzled stare, “Yes” she
said quietly and nervously, “I have always wanted a baby and all the jerks I
have been would run in a second. I know what you are like with kids and how
dedicated you are, having a baby with you would be the most amazing thing.”

“I don’t know what to say... if we do this, it
will complicate things in the future, what the hell would we do?”

“I don’t know, I wouldn’t expect you to leave sis,
all I know is that you would be there for us like you always have been.”

I looked at her, the other women in my life that I
have always loved, “I want you so much and I would love to have a baby with
you.” I didn’t know what else to say, I was scared that if I said no, I
wouldn’t be able to fuck the living shit out of her.

She smiled her eyes lit open and pulled me to her
lips kissing me firmly and said “then you better get that hard cock of yours
into my soaking pussy right now!”

With that said I got up and pulled down her jeans,
she awkwardly took of her top and bra as I then revealed her in just her
knickers. I moved down and kissed on her pussy breathing in her pussy smells
like I did when I masturbated in her underwear.

My tongue traced all over her undies and to the
edges, I pulled them to the side to reveal a very sexy and trimmed pussy. Her
pussy was glazed from her excitement and I slid my tongue over her clit...”Oh
damn!” she moaned out, I began to eat her pussy like a pro making her quiver
with every lick.

“Dont make me cum yet.” She moaned out, I slid my
tongue away and down her thing, her body was shaking from the pleasure.

I pulled her knickers down and I was naked in seconds, she laid there
one arm above her head and the other rubbing around her pussy, I took my cock
in my hand and started to stroke it...already there was precum ozzing out of
me.

I climbed on top of her and lowered my hips onto
hers, out bodies shuddered from each other’s naked touch and began grinding
into each other.

My cock quickly opening her lips to rub against
her drenched clit...”Ahhh” she sighed as we slide against each other, I moved
up and down on her with more rhythm.

The tip of my throbbing cock kept slipping above
her hole, making her gasp every time.

We kissed like it was our lives at stack, fast,
hard and very slippery.

I lifted my hips and positioned the tip of my cock
above her hole and held it there for a few moments...we looked at each other
deeply and her hand then moved onto my ass and pushed my hips down...

My swollen member penetrated her pussy with a
popping action and we both moaned out load, I then pulled out feeling her
juices on the tip of my cock...I was twitching so badly and I knew this would
not be a long fuck.

Hand still on my ass she firmly pushed again
lowering me down and this tip all the way to the hilt, I bit her shoulder as I
reached deep inside her and began moving up and down in a slow rhythm.

Our tongues slid over each others as we fucked in
a good steady rhythm, we were so wet together and the sound of it was sending
me over the edge. I lifted her arms above her head and held her hands holding
her down, I began speeding up more faster fucking her tight swollen pussy more
and more...her pussy was so slippery but was contracting on my cock with every
thrust.

Faster and faster I pumped into her, she was
moaning and saying something that I couldn’t hear exactly, but I can only
presume it was good as she was sighing and biting her lip. My balls tightened
and I fucked her heavenly pussy with everything I had making her body jut
hard...

We looked into each others eyes as our body’s slammed
together, "I wanna cum baby, I wanna cum inside you. I've dreamt of it this
moment for so long."

She smiled with her amazingly deep, beautiful blue
eyes. "So have I sweaty. I want you to fill me up with your love hot spunk,
fill my pussy up now! I'm going to cum too" I couldn’t believe it, I was
in heaven.

I kept my eyes opened, we both moaned out louder
and louder as our bodies became one, my cock swelled, her pussy gripped even
more as she was about to orgasm all over me. I let out one last moan, “I’m
coming...” and with that shot wads of hot, thick spunk deep into her pussy, she
screamed, OH MY GOD!" as I spirited deep inside her cunt filling her pussy,
she moaned out so loud and said “me too!” and climaxed all over me. Our bodies
stired as our cum mixed and I fell on top of her resting on her shoulders. Our
body’s panting heavily from the most amazing fuck of our lives.

My cock rested inside her soaking fucked pussy, my
cock still twitching and dribbling out cum. I could feel the juices oozing out
of her.

I kissed her chest and we layed in silence for a
minute or two.

"That was amazing." she said, I smiled
and looked up at her, "God yea it was, you are so beautiful, you don’t
know how much I am in love with you." She looked at me with such deep
emotion. “I know hunny” and kissed me softly.

“I can feel your cum in me, I feel exceedingly
filled.”

“Mmm, that’s exactly what we want.” I said.

We layed side by side of each other starring and
smiling at one another for what felt like forever...”This isn’t it is it?” she
asked, “No no, I wanna make sure that my seed has done its job.” And smiled at
her...”Mmm...more where that came from huh!” she said cheekily. “We have done
it now and I don’t want it to ever stop. I want you to have our baby, I want us
to be with each other as much as possible. I know its going to be really
difficult, but I won’t let go of either of you. I’m greedy!” and winked at her.

We kissed and she said, “As long as your there for
me and our baby, you will always have me and my heart.” With that we held each
other and fell asleep.

I went to see her a few days later and she had
already taken a pregnancy test, it was negative and much to our pleasure, meant
we were going to have another intense session.

Soon after she informed me that she was indeed
pregnant and we were over the moon. Her sister was really excited for her and
we both went to the hospital over the following months for the scans.

In a late May she gave birth to our beautiful son.
A couple of years later me and my wife had a beautiful baby girl. It may seem
like I am a complete scumbag for what I did, but all of us are extremely happy
and in love and this only has made us extremely close with each other. It’s an
amazing bond, though there is this very dark secret.
