(in) Decent Proposal

I'm Paul, and I am married to my beautiful wife Lisa.

Lisa was my childhood girlfriend and we were in the same class at school. We are now both forty six years old and very happily married, I am an only child and Lisa has a sister called Nikki who is four years older than her.

Despite approaching fifty Nikki actually looks about thirty five, she looks amazing for her age.

Lisa and Nikki were easily the prettiest girls in our school, so I felt very lucky to have Lisa as my girlfriend. As Nikki was older than us she had matured into a beautiful sexy woman by the time we left school, everyone that I knew fancied her.

Nikki didn't seem to have many boyfriends but when she was almost thirty she became pregnant, she gave birth to a girl called Beth and all seemed perfect in her life until it was revealed that the father of her baby had been lying to her, he was actually married had two other children and he was leading a double life. This revelation destroyed Nikki's life and her trust in men. She decided to raise her baby on her own with a little help from family members including Lisa and myself.

After Lisa and I bought our first house Nikki and Beth spent a lot of time at our place and it was great having them around, we all got on really well, and Beth was the bridesmaid at our wedding.

Beth is an adult now and she is living away as she is studying at university.

Nikki still spends a lot of time with us as she doesn't like to be alone.

One evening we all decided to have a holiday abroad together, so I let the girls decide where we should go and Lisa was going to book it.

A few days later Lisa told me that the three of us would be staying in an adults only All Inclusive hotel on the Canary island of Tenerife. We were all very excited as it looked amazing.

Two weeks before we were due to fly to Tenerife Lisa and I were talking when she said, "I haven't been completely honest with you about the holiday that I have booked for us. I will not be going but Nikki is still going with you as planned."

She went on to explain that it will be Nikki's fiftieth birthday during the holiday and as she has been on her own for many years while raising her daughter Beth she wants her to have a special birthday treat, and that treat is going to be me!

Lisa had already spoken to Nikki about it and she was very happy with the arrangement.

"You and Nikki have always been very close and Nikki has told me many times that she fancies you, I have told her many times about our sex life including how you are obsessed with eating pussy, there are no secrets between sisters. If you are happy to go along with it you have my absolute permission to do whatever the two of you want to do during the holiday."

"Are you suggesting that we can have sex?" I asked.

"Yes, that is the whole idea, it will be Nikki's birthday present from us, she has been celibate for eighteen years and she is so excited to spend some personal time with you, I want you to thoroughly spoil her and treat her with the same respect that you have shown me throughout our marriage."

"I know Nikki and I have flirted with each other for years but this is taking it to another level, I don't want it to destroy our marriage."

"You both have my permission 100% so it's not like you are cheating. I have been thinking about this for a very long time and I am very comfortable with the idea. But, after the holiday it ends completely, and unless I specifically ask what you got up to I don't want to know what went on between you two."

The following day Nikki called at our house and the atmosphere was somewhat awkward, Lisa said "Nikki, I have explained the holiday plans to Paul and he is very happy with everything we discussed."

"You really mean everything?" Replied Nikki.

I looked at Nikki and she was biting her bottom lip and smiling at the same time we stared at each other for what seemed like forever until I held out my arms and we hugged. I didn't really know what to say as it was such an unusual situation but the hug seemed to break the tension and we both felt better about it.

"Treat it like a honeymoon and enjoy yourselves and each other." Said Lisa.

"That's a great idea, I'm sure it will be amazing." I replied.

Nikki said, "Wow, I can't wait to leave I am going shopping for some nice clothes to wear in Tenerife."

Lisa and Nikki got ready and went to the nearby shopping centre and were gone for hours. When they returned Lisa said "You are in for a treat on holiday."

Nikki went red with embarrassment, "Any chance of a preview." I asked cheekily.

"No, you can wait for the surprise, I just hope you like it." Said Nikki.

"I'm sure I will."

The morning of our flight while waiting for the taxi to pick up Nikki and I Lisa said to me, "I'm still 100% happy with what is about to happen and I wish you both an amazing time, you can do whatever you and Nikki decide to do but please don't forget who your wife is. I don't want this to ever end our marriage."

"I promise you that I will not let it affect our marriage, you are the love of my life and that will never change." I replied.

The taxi arrived to take Nikki and I to the airport, I gave my wife a big kiss and a cuddle and we were gone.

When we arrived at our hotel we found it to be beautiful, the whole resort was just perfect. We were taken to our suite which had a huge super king size bed.

After unpacking we went for a walk to familiarise ourselves with the surroundings.

We went into one of the bars and had a few drinks. Then we went back to the suite to shower and get ready for dinner.

As we were in a suite one of us could sit in the living room while the other showered and changed to give each other some privacy.

I got showered first and then Nikki went in once I was finished.

Once she was ready Nikki walked into the living room and wow she looked amazing, she was wearing a red dress that reached to a few inches above her knees, showing her magnificent legs, it also revealed a lot of cleavage and her perfectly shaped arse which excited me a lot.

Nikki had styled her short brown hair and with her stunning green eyes complimenting her make up I felt like the luckiest man alive.

"You look absolutely beautiful Nikki."

"You look very handsome too Paul."

As we left the suite Nikki took hold of my hand which felt really nice as we went to the restaurant looking like we had been together for years.

Dinner was very nice but neither of us ate much, we were both slightly nervous about what was going to happen later. Even though we knew that we would be having sex it still had that first date feeling.

We agreed to go to one of the bars and have a couple of drinks to calm our nerves, there was a lovely quiet bar with a pianist playing in the corner. It was perfect as we could have a talk and relax.

The waiter came over to our table and we ordered a couple of cocktails, while we were waiting for them to arrive Nikki leaned into me, put her hand on the back of my neck and kissed me on the lips. "Thank you for agreeing to this holiday Paul."

Although the kiss was just a quick peck it felt wonderful and it broke the ice, that first date feeling vanished and we felt more like a couple.

"You're welcome Nikki, it has been a lovely day and we have quite a few more days together and it is only going to get better." I replied.

Following the kiss we sat closer together and we would hold hands and touch each other as we talked and laughed. At one point Nikki placed my hand on her thigh, just above her knee, her skin felt soft and I was excited about touching even more of her later.

It was probably the few drinks that we had that relaxed us both but everything felt right and I'm sure we looked just like all the other loving couples in the bar.

After a couple more drinks we decided it was time to leave.

Between our room and the bar there was a viewing balcony overlooking the Atlantic Ocean where people could watch the sun set. On the way back to our room we stopped and stared silently at the blackness of the sea and sky as the sun had set hours earlier.

I put my arm around Nikki's shoulders as we stood side by side and said, "I never realised that darkness could be so beautiful."

Nikki turned to face me and I gently held her face in my hands and leaned forward to kiss her, this time it was not a quick peck but a full on tongue swapping lovers kiss as Nikki responded by putting her arms around my neck and pulling me tightly against her. I could feel her big perfect breasts pressing against my chest and my cock started to harden.

After we broke the kiss Nikki said, "I hope tonight never ends."

I took her hand and we walked back to our room, I think by now we both clearly understood what was going to happen next.

On the way to the room we stopped three more times just to stop and kiss some more.

Once in the room Nikki said, "give me a few minutes." As she picked up a few things and went into the bathroom.

About ten minutes later she came back into the bedroom and I was speechless, she looked absolutely beautiful, wearing just a very short white silk and lace babydoll nightie and matching panties, her breasts bounced slightly as she walked towards me, Nikki smiled and said, "I hope you like it."

"It is absolutely perfect, I love it." Was all I could say as my cock started to harden.

I took a good look at the beautiful sight before me, and my eyes were drawn to the bulging pussy mound and the camel toe concealed in her panties.

I was still wearing my shirt and trousers and I felt very overdressed.

I started to unbutton my shirt, "allow me." Said Nikki.

As she started to undo my shirt buttons she kissed me again and my cock reached full hardness causing an obvious bulge in my trousers, Nikki could feel the effect she was having on me as she pushed her pussy against my erection. "Ooh, that feels nice." Said Nikki.

She fully removed my shirt and started to unbuckle the belt on my trousers, quickly followed by the fastenings and the zip, my trousers fell to the floor and I stepped out of them. I took off my socks and was down to just my boxers, we started to kiss again but this time Nikki had one hand on the back of my head and her other hand was stroking my cock, my hands were caressing her magnificent tits.

I slipped the small straps of the babydoll over Nikki's shoulders and it dropped down her body landing at her feet, she stepped out of it.

She was as beautiful and sexy as I had always imagined. I would guess her breasts were a 38D, suffice to say that they were really big, and capped with very large pink areola and hard nipples, Nikki was perfection.

I removed my boxers and we laid down on the bed with our heads on the pillows, we were facing each other and smiling, it was a strange situation to be in with my sister in law but at the same time it just felt so right.

We started to kiss, Nikki was a fantastic kisser, she would nibble my bottom lip and suck on my tongue as we kissed, and my cock reached full hardness in seconds, she giggled when she felt it touch her thigh.

She reached between my legs and took hold of my hard cock, her eyes opened wide, "Ooooh, Lisa wasn't exaggerating about the size of your cock." She said, while smiling at me.

It seemed that there certainly wasn't any secrets between sisters.

I started to kiss Nikki's neck as she stroked my cock, "oh yes I love that, please Paul kiss me all over."

"I certainly intend to kiss every inch of you."

I had to adjust my position as I moved down Nikki's body, this made her release my cock but I wanted this night to be all about her happiness and satisfaction.

I continued kissing her neck as she tilted her head back to allow me full access to her. I cupped both of her tits in my big hands, her nipples were already hard and I tweaked them between my fingers. I continued kissing down from her neck onto her chest and towards her tits until I reached her soft areola and hard nipple, I licked it so lightly then bit it gently before sucking on it like a starving baby.

Then I moved onto the other tit doing the same. My hand was travelling down her sexy body towards her pussy, my lips and tongue were quickly following tasting her skin as I headed towards my prize.

I placed soft kisses on her pussy mound through her panties, there was a definite wet spot where her panties had entered her pussy.

I put the fingers of both my hands inside the waistband of her panties and instinctively Nikki lifted herself up from the bed to allow me to remove them.

As she laid back down I couldn't resist licking the wetness from her panties, "mmmm, that tastes good."

"You naughty boy, I'm glad you enjoyed it because I have plenty more for you."

Now I was completely between her legs, I placed her lovely long legs over my shoulders and began to kiss her thighs starting just above her knee, I trailed kisses up one leg and then the other, finally arriving at her beautiful soft, wet, shaved pussy, there wasn't a single hair or even the trace of a hair, I took a gentle lick between her labia and I was rewarded with the delicious taste of her pussy.

Her legs were now spread wide open and the heels of her feet were pressed firmly into my back.

I placed my thumbs either side of her wet slit on her outer labia and slowly opened her up, the sight before me took my breath away, Nikki had the most beautiful perfect pussy I could have ever imagined, the inner labia were quite large, and her vaginal entrance looked almost virginal, it was all a lovely shade of pink topped off with a beautiful pearl like clitoris popping out of its hood. I was in pussy eating heaven.

She moaned as I explored her pussy with my tongue putting it deep inside her and she groaned as I put first one and then two fingers inside her also. She was very wet and oh so tasty. My tongue moved up and found her clitoris, I licked and sucked on it and she responded by pulling my face even closer into her wetness.

"Oh yes Paul, eat me, make me cum and then fuck me," she said.

This was the first time I had ever heard Nikki swear, so I was very surprised but I never stopped licking her delicious pussy until she screamed and writhed against my face until she cum, she was breathless from her orgasm so I cuddled her until she was breathing normal again.

"It seems everything Lisa told me about you is true, she said you were amazing with your tongue."

"I am glad you enjoyed it, I certainly did and we haven't finished yet."

My cock was now rock hard and wet, so I knelt between her legs and as I caressed her big tits Nikki reached between her legs took hold of my cock and guided it into her pussy, finally I was inside this beautiful sexy woman, I'd fantasised about this moment since Lisa told me of her idea.

I started to slide my length in and out of her soaking pussy and Nikki met my thrusts by pushing her hips upward to meet me every time.

It was pure passion, not raw hard fucking.

I leaned forward and was now laying on top of Nikki, I looked into her eyes and they were filled with tears, our lips met and we kissed non stop as Nikki had her arms around my back pulling me against her so tightly.

I was now ready to cum and I unloaded streams of cum into her pussy, I could feel her pussy pulsating as we shared an amazing orgasm together.

We laid on the bed facing each other, both exhausted with enormous smiles on our faces.

"You looked very tearful."

"They were tears of happiness, I now know how it feels when someone makes love to me, I have never felt so loved or wanted in my life, thank you for today, you have made me feel like a woman again."

I had to agree with Nikki, this wasn't fucking or sex, this was beautiful passionate love making.

I had to keep reminding myself that I have a beautiful wife at home and I promised her that I wouldn't fall in love with Nikki, but I was struggling to control my emotions and feelings for her.

We fell asleep while cuddling in bed, I was first to wake in the morning, I put on a pair of shorts made a cup of tea and sat on the balcony just as the sun rose.

The view was spectacular and the sky was clear, it looked like it was going to be a lovely hot day.

I received a text notification, it was from Lisa reminding me that today was Nikki's birthday it also said 'I hope you are looking after my big sister.' Followed by a winking emoji.

I heard Nikki getting out of bed and going to the bathroom so I made her a cup of coffee, when she came outside onto the balcony I said "Happy birthday darling," and gave her a big hug.

"Good morning Paul, that was a lovely greeting." She replied.

I suddenly realised I had never called her darling before, that is something I only ever call Lisa, after just one day I was thinking maybe I am getting too emotionally involved already?

This was supposed to be a pretend honeymoon but in felt very real to me.

"It looks like a lovely day, what would you like to do?" I asked.

"I want to relax and take it easy."

"How about we have breakfast then take a stroll along the beach, then spend the morning at the pool."

"Sounds perfect to me, that's a great way to start to my birthday."

Nikki then put her arms around me and kissed me with a passion that I've never known.

"Wow, that's what I call a good morning kiss." I said.

"Well, it is our honeymoon." She replied and giggled then went into the bathroom for a shower.

After we had showered we went to the restaurant and ate a delicious breakfast, then as planned we walked along the beach.

I asked Nikki why she had been on her own for so many years.

"I have only been in three relationships, and was treated very badly in all of them, the first one when I was seventeen cheated on me with numerous girls, the second one a couple of years later was very controlling and abusive and the third one was Beth's father and you know what he did to me. So I took the decision to raise Beth alone and keep men out of my life for her safety."

I hugged her tightly and said, "not all men are like that, but I understand why you chose to stay single."

"If I had met you all those years ago before you started dating Lisa I'm sure my life would have been very different, but let's not dwell on the past and enjoy ourselves while we can."

Nikki was right and we returned to the hotel, we got changed and went to the pool.

Nikki had chosen a white bikini and she looked stunning as always.

She was getting many looks from other men and some jealous women. I felt like the cat that got the cream.

While we sunbathed I said to Nikki, "as it's your birthday today I want you to be in control of whatever we do in the bedroom, if there is anything you would like me to do or anything that you have ever fantasised about in your life I will happily do it for you."

"Mmmm, I am sure I can think of a few things, to be honest with you, despite my age I am very inexperienced when it comes to sex, but there is certainly a couple of things that Lisa has told me about that I am interested in trying with you."

"Sounds very interesting, just remember I mean absolutely anything." I replied.

"Rather than explaining what I would like to do I will show you when we get back to our room."

I was really excited to find out what Nikki had planned and hopefully I wouldn't have to wait too long.

Nikki and I went into the pool to cool down from the extreme heat, after about twenty minutes we agreed it was time to go to our suite and have a break from the sunshine.

Once we arrived in our bedroom Nikki said, "I'm really horny and I want to show you the first of my fantasies."

I held out my arms and said "Help yourself."

I removed my pool shorts and Nikki took off her bikini, as always she looked incredibly sexy.
