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.
