Joanna my beautiful sister

We are twins, just minutes apart, I am the eldest of us two, I am Dave, my kid brother is called John. When we grew up I was always the responsible one, the one that protected my kid brother, I loved him, simple as that. Our parents are very loving parents, liberal minded too. My father Ingvar is a painter, he was born in Sweden and moved to the States when he was 3. He paints nude models, mostly girls which was great fun for boys growing up, especially if you knew which hole to peek through. Watching these often very beautiful girls, we had many a boner.
Our mother Mary is a typical mum, very loving and caring, she is a history teacher at the town highschool. She is strong on human rights in general, never prejudiced.

We had a very happy childhood, we did things that boys would do in their youth, we built model airplanes, went fishing, watched porn together when our parents were away, built and raced our first hotrod when we were 16.
Just two boys, nothing out of the ordinary. But at some point things started to change, they changed so gradually, that at first I did not even notice. But one afternoon it suddenly struck me that my kid brother seemed "different", I could not put my finger at it.

So I watched him closely in the days to come.
It seemed he did not enjoy our "boys" things as much as he used to and another thing that struck me as odd, it looked like he plucked his eyebrows. They looked very different from mine.
But I did not want to hassle him, so I let him be. It was just a small taste of things to come.
My brother was obviously struggling with something, but he was hesitant to confide in me, which saddened me. I worried that he was being bullied at school and was ashamed to tell me, I could not have been further from the truth.

This went on without change and one day I had a real shocker. I passed the bathroom and saw my mother undressing, but then I realised I just saw her downstairs. So I peeked through the opening between door and sill and saw my kid brother undressing, he was taking off a dress which I recognized as my mother's. I went to my room, disturbed, not knowing what to make of what I just saw. Since John did not see me watching, we could avoid a discussion, I did not feel like confronting him, I didn't know how to react.

After a few days I almost burst and had to tell someone, so I confided in Mum, to my surprise she already knew about John's "issue". Probably I will never figure out how he did it, but all these years he managed to keep hidden, that he was not happy being a boy, well he could have fooled me.

We talked about girls and watched porn together and his boner looked as big as mine so he was as excited watching it as I was. At some time we even thought it would be exciting to give each other a handjob while watching, to create the illusion that one of the girls in the movie was doing it. So we knew our way around each others dick. And now my mom was telling me that John was unhappy being a boy? That was a little too much for me, I didn't know how to handle that.
Especially since she told me that I would see John change, he would be starting his hormone treatment shortly.

But, you don't have liberal minded parents for nothing, so I got used to the idea of having a sister quickly.
Months passed, John's features started softening, he had something done to his nose and chin and got breast implants.
I must confess, my kid brother was turning into a girl and not just a girl, a real hottie. Although thinking about my new sister this way felt kinda strange. I did not know what to do with these new feelings. The brother I knew was gone, but the new sister was alien to me, we did not share a youth together, as brothers yes, but a brother sister relationship never existed.

So although she was my sister now, I looked at Joanna as a beautiful girl, a girl I would even like to date, these feelings confused me immensely. You should not feel like that for your new sister, former brother, but I did.

We had a great summer this particular year, evenings were long and hot. I felt like a ride so I eased my 1978 FX Super Glide out of the garage for a spin. I changed it from a standard bike to a bad looking chopper with a solo seat, just the way I wanted it to look. I kicked it over a few times and then started it, I let it tick over on the driveway and walked to the house to get my gloves and goggles. I bumped into Joanna, she asked if she could tag along for the ride. I told her o.k. but she had to sit on the rear fender and fold her legs around my middle since no passenger steps were fitted to the bike.

Joanna did as I suggested and we cruised to the shopping mall, maybe get an icecram, something like that. We must have been a great looking pair, a butch biker and his 6ft. tall slim babe with long dark blond hair, long slightly musculair legs in skinny jeans and a great pair of size D boobs. We went over to the ice cream shop and unfortunately ran into some very obnoxious class mates of Joanna's.
They felt it necessary to call her freak, call her names, one of them even made a move towards her. But before he could do anything he was face down on the ground with a mouth full of blood, being captain of the boxing team does come in handy sometimes.

Joanna kept her dignity, but I could see how hurt she was, so what should have been a nice summer evening, turned into something nasty. We went home and I gunned the throttle of my Harley, I felt Joanna clinging to me for dear life.

When we came home, we found our parents gone, they left a note that they were off to the cinema for a late night movie, we should not stay up for them.

Joanna burst into tears about the incident at the mall, she was very hurt, just as she was becoming more self assured, the incident could not have come at a worse time, stupid bigots.
I tried to console her, but she kept sobbing, so I stroked her hair and told her everything would be fine and I would be there to look out for her.
She looked up and I looked into her beautiful teary eyes, I was lost and she knew it too. Joanna kissed me and it turned into a long passionate kiss.

"Well, that was a long time coming", she said with a smile.
"Glad that's out of the way", I said.
"What do you feel for me Dave?"
"I think you are a beautiful girl, but I don't have the kind of feelings a brother should have for you. You excite me somehow."
"I feel the same about you and I love you for standing up for me, the way you did at the mall."
"You are my sister, it's only natural that I would do that."
"No I don't think so Dave, I can't think of other boys I know, who would have protected their new sister like you did."
"That's because you are my sister and I love you."
"I love you to Dave."

And then she almost floored me with her next remark.
"I want to make love to you, would you like to make love to me? I want the first time to be very special, with someone I love and trust and I can't think of anyone better suited than you."

I was speechless, making love to my sister? Incest? But then the idea of making love to Joanna was very appealing. So I said "Yes, I want to make love to you."

Joanna rushed off to the bathroom.
"I want to smell nice and be clean for you", she said.
I did not mind, but she seemed to take forever. But since our parents would not be home for hours, there was no need to rush, I tried to relax.

She blew my mind when she came out of the bathroom, fresh make-up, smelling oh so good and wearing sexy lingerie.
"Your turn now", she said.
I hurried to wash up, brush my teeth, shave and put on some aftershave. I could not have been more excited, I was going to make love to my sister, yesss!!
When I entered her bedroom I was once again struck by her utter beauty and sexuality, I wanted to make love to her so bad, that it almost hurt. I laid myself down on the bed beside her and we started kissing, she tasted sweet and innocent. It all felt very natural, I had no reserve kissing her this way. It was even more exciting than it had been with other girls, maybe because this was forbidden love?

I fondled her soft, big breasts, kissed and sucked her erect nipples, she moaned softly. I freed one hand to reach for her panty and felt a small bulge. Then I realised that Joanna still had her penis. She once told me, that she had not yet decided if she wanted to keep it or not, but somehow I forgot. At the time I didn't think it important, after all she was my sister.
So her still having her penis wasn't a big thing to me, in fact it wasn't a big thing anymore. Maybe the hormone treatment did that, I don't know, I 'm no doctor.

"Does it turn you off, that I still have my penis?"
"Hell no, you are my sister, with or without and we played with each other's dicks when we were younger and secretly watching porn. I don't mind, somehow it even adds another dimension to things. You are more beautiful than any other girl I have been with, but with a secret bonus. Making love to you will be extra special."

This is what she had been longing to hear, it set her mind at ease and excited her. She pulled down my boxer shorts and started to go down on my already erect cock, the sensation of Joanna's moist lips moving over the tip of my cock and feeling her tongue turning circles was almost unbearable. I thought I would come there and then.

"Jesus sis, where did you learn to do that?"
"I watched a lot of porn together with you, remember?", she smiled and wrinkled her nose which looked incredibly sexy. I felt like the happiest man on earth.
She continued and she almost had me ready to shoot my load.

"Oh no, I don't wanna come yet, hold it please Joanna, this feels way too good. I have to cool down for a minute."
We started kissing again and I gently rubbed her groin, I felt her penis grow. She writhed and moaned softly, like she was in pain so I stopped.
"Oh please dont stop, it feels so good for you to touch me there, I trust you and I know it will be good."
"Would you like me to go down on you?"
"Only if you really want it, not because you feel you have to return the favor."

The fact that Joanna had a dick, made the whole situation even more forbidden and exciting, like making love to your own sister was not exciting enough.
It felt a little strange at first switching roles, but it made me incredibly horny to have Joanna's dick in my mouth, it felt o.k. though since it was Joanna's dick and not some other guy's dick. I could see Joanna enjoy my very first blowjob thoroughly, she felt completely at ease with it and so did I. It was a step forward from giving each other a handjob when she was still John, but a natural step up in our relation.

"Dave, this feels really great, but I am getting so incredibly horny, I want you to fuck me, are you o.k. with that?"
"More than o.k., how do we do that?"
"Dave, I am disappointed in you I thought you more of a man, have you never fucked a girl before?", Joanna said accusingly with a smile on her face.
"Well yes I have but...."
"Yes, right you are in my butt, but first I'll get some lube, to make it easier."

Joanna applied lube liberally to her love hole, awaiting entrance of my rock hard dick.
"Now put the tip of you dick against my hole and push ever so gently you have a big dick, so I have to relax to let it in."

I pushed against her bleached and waxed anus, it looked clean and innocent.I was very excited and I feared I would come and shoot my load all over her nice ass.
Suddenly I felt her muscles relaxing and my dick slid in, Joanna sighed, it was warm and very tight inside her, nothing like a pussy.

I started to move slowly, in and out and I kissed my sister on the back and in her neck, she smiled and tossed her hair back, I looked into her eyes filled with anticipation.
"I like how you are fucking me Dave, it feels so good, please never stop doing that."

It was next to impossible to imagine that the beautiful girl I was making love to, was once my brother, she did not resemble him in any way anymore.
"Your dick feels good inside me Dave, coul you try and fuck me a little harder? I want to see how it feels."

As if I was not excited enough, but I did as I was asked to and heard my body slap against her curvaceous ass. She moaned and made little noises that were akin to purring of a cat, it made me even hornier. I could hardly contain myself I wanted to ram my cock inside her, feel her ass slam against my body. I tried to remember she was my kid sister, but I forgot, I grabbed her by the hips and pulled her towards me with force. Her ass slammed against me really hard.

"Uhh, uhh, uhh, don't stop Dave you are really fucking me know, fuck your little sister, I'm your bitch."
So I fucked her as hard I could to exhaustion.
"I'm out of breath sis, let's change positions."
"O.k. you want me to ride you big brother? Because I will really ride you, your fucking has made me so horny.", she said in a develish tone of voice.

I laid myself down on the bed and watched Joanna straddle my hard cock, now I could see that she was really excited, her cock was almost as hard as mine, but not quite.
She started riding my cock, I saw her excited face and watched her great looking boobs bounce up and down. I put my hands around her waist to move her up and down.

"I 'm so horny big brother, I'm going to ride you till you come deep inside me, I love you so much."
"Love you too little sister, I can take whatever you want to dish out."
Seems like Joanna got hornier by the minute, she rode me like you would ride a bucking bronco. While she rode me with all her might, I tried to jerk her off, which excited her even more as she responded with an incredible fierceness. I was almost painful the way she rode me, but I felt my balls contracting and approaching the boiling point.

Joanna beat me to it and lost her load on my belly, I was not far behind, when she came I felt her anal muscles contract. A few times up and down made me shoot my load deep into my sister, it was a roaring orgasm, I embraced her and kept pumping, she milked my cock completely dry.
We ended our love making with a long and passionate kiss, this experience was unreal and not matched by previous experiences I had with other girls.

Lucky for us, this particular summer was a very hot and very long one, our parents made the best of it by going out for drinks until late, on some terrace or other. We were always very excited when upon coming home, we found a note saying not to wait up for them.

This summer Joanna and I really connected, we got very close. But all good things must come to an end and this beautiful summer ended way too quickly.
But we got more and more inventive in finding ways to spend quality time without our parents knowing.

In the years to come we both got into a relationship, but unfortunately our relationships were not sexually fulfilling. So Joanna and I kept meeting on stolen afternoons or weekends, anything we could put a business related event in without arousing the suspicion of our spouses. This was not very difficult, since our partners trusted us.

A few weeks ago, Joanna and I managed to get accepted for an event which is planned in Greece. We just have to attend and the event will take ten glorious days. We will be sorely missed at home, and we will miss our beloved ones.

We will just have to console each other in the ten days we are away from home. We are both very excited at the thought of all that precious time we can spend together.

My beautiful sister and I.
