I fuck my sister in Plymouth.

100% fiction!

I was serving in the RAF at the time of this account and specialised in sorting out problems on aircraft. I was sent to airfields in the UK and in Germany. As a result I was rarely in one place for more than a few days so was unable to become sexually invoved with women. When necessary I would masturbate.

My sister, Pat, was married to Jack who was in the Navy. His ship`s home port was Devonport and Pat and Jack had a house on the outskirts of Plymouth. At the time he was in his ship and would be away for several months.

Because I moved frequently from one place to another Pat never knew where I was so couldn`t telephone me so I telephoned her to keep in touch. As I was due for some leave she invited me to spend it with her. When I arrived and were chatting she asked me if I had yet got a girl friend. When I said I hadn`t she said "What do you do about sex, then?"
I could hardly say to my sister that I masturbated and all I could stammer was "Well, I, er, um...".
"Out with it" Pat said. "You masturbate, don`t you?".
I replied that I was ashamed to say that I did.

"Why be ashamed? Jack does it when he is away to keep on the straight and narrow. So do I because I miss our sex when he is away".
The next day, being warm and sunny Pat suggested we take a picnic to a beach, not far away, in Cornwall. Arriving there, we carefully undressed under large beach towels and put on swimming gear. I wore black swimming briefs and she a two-piece costume, not a bikini. Until then I hadn`t realised what a lovely figure she had. I had never been so close to a woman in a brief bathing costume and although Pat was my sister I felt my cock growing in my briefs. I knew it shouldn`t happen but it did.

Pat seemed amused when she saw the bulge in my bathers and said "It`s all right, George. Don`t worry. I don`t mind. I`m rather pleased that I have that effect on you. It gives me quite a boost".
We swam for a while and the cool water made my cock return to a limp state. We dried off, had our picnic and dressed. Returning to Pat`s house we had several glasses of wine before and during a meal that she had cooked. After the meal we had brandies and were rather merry. Perhaps a little indiscrete.

"You know, George" Pat said " liked it when you had that erection on the beach. Could I see it for real?"
"You want me to take it out of my trousers?"
"No. I want to see all of it".
"I would have to undress to do that. Surely I shouldn`t do that. After all, you are my sister. I`d be naked in front of you".
"Of course" she replied. "That`s the only way for me to see it properly. No-one will know".

Here, I should confess that I liked the idea of stripping naked for Pat.
"All right, then. I`ll do it" and in no time I stood naked before my sister and began to get a slight hard-on, which she could see.
She said "It`s not right up. I want to see it fully up to see how big it is". A strange request, I thought, but was happy to oblige her.
"I`ll get it up for you".
"No. Can I do it".
"That would mean you would have to hold it. Do you think you should?"
"Yes. May I?"

"Please do", and with that she took hold of my prick and stroked it to full erection. Though I was in my late twenties I had never had a girl hold my cock, let alone stroke it. And it was my sister who was doing what she shouln`t. I certainly didn`t object. I liked it.

Now I had a full erection Pat said "Goodness. What a size. You said you didn`t have a girl friend. Do you mean to say that you`ve never put it into a girl?"
"No. I`ve never had sex".
"What a waste of an erection like that".

She released my cock and it began to shrink a little.
"Pat," I said "You can see me naked and all I`ve seen of you is in your bathers. Can`t I see you in the nude?"
"Only if you promise to behave if I do undress".
"I promise".
"All right then. Here goes" and there and then she stripped naked. The good figure I`d seen in her bathers was confirmed. Firm breasts with erect nipples, flat stomach, shaven pussy and long, slender legs. This was the first naked woman I`d seen, though I`d seen picturs of naked girls in men`s magazines. My cock grew again.

"You like seeing me naked" said Pat.
"I certainly do, but you have just partly masturbated me and I would like to do the same to you".
"But you promised to behave, George".
"You didn`t behave with me".
"That`s right. I didn`t. OK then. Do it."

She guided my hand to the entrance to her pussy. She knew how inexperiencd I was and told me to put my fingers into her, even helping me to do it. The tips of my finger felt something and she told me it was her clit. I had no idea what a clit was.
"Now caress it" which I did and I felt it hardening.
"Oh. That`s nice" she said. "Don`t stop. I want you to make me cum." This was from some-one who had told me I must behave.

In a short while she began to gasp and cried out "I`m cumming! It`s lovely". Then, "Take your fingers out".
When I did we sat together on a settee, still naked.
"You didn`t make me cum" I said.
"No. I didn`t and now I think it would be a terrible waste. I can think of a better way to make you cum. Do it in me".

Again I remembered she had said I must behave. Now my sister was inviting me to fuck her. Should I? I`d never fucked a girl, though of course I knew what that meant. I must say I wanted to have my first sex and it would be with my sister if I did fuck her.
"I want to fuck you" told her, "though I shouldn`t do it to my sister".
"So what? she replied "I want that big cock in me. Who would know? Let`s go to your bedroom".

Naked, we went upstairs to the bedroom I`d been given. We lay side by side on the bed and began masturbating each other, being careful not to cum. My prick was at full size now. Pat opened her legs and I could see the lips of her cunt were open. She then told me to lie on top of her and when I did she held my erection and put it to the entrance to her pussy.
"Now push it in me, slowly".

Gently I slid in. I now know why it went in so smoothly. I had fully masturbated her and her vagina was lubricated with he cum.
I slowly thrust in and out of her, then, as I neared ejaculation my thrusts became faster and faster. Soon, I was shooting my cum into her. Pat was crying out "I`m cumming! I`m cumming!"
When I`d finished ejaculating I pulled out of her cunt but she said "I haven`t finished. Put it in again".

I did and contiued fucking her until she had cum several times and was satisfied. Something else I`d learned. Women can have several orgasms one after the other.
We lay side by side again and Pat said "That was the first sex you have had. You did very well. I loved the way you fucked me. We must do it again before you go back. Perhaps we could do it in the open next time. I know of a place in some woods not far from here where we can do it".

We had committed incest and she had been unfaithful to her husband. Neither if us were concerned and we were going to do it again. We did, in the woods and in the bedroom.
The first time I had fucked a woman was with my sister.

That was some years ago. Now I am married and I shall never tell my wife about it, of course, and my sister has told me that she will never tell Jack.
