While sitting at my computer reading incest stories on literotica.com, my mind goes back to the time when I first fucked my sister Margaret. It was 1945 and soon after my 19th birthday. Margaret was an 18-year-old lovely looking girl, filling out in all the right places, a nice tight round firm arse, long shapely legs and a gorgeous pair of tits with quite large nipples. Margaret really was beautiful.
We had been fooling around wrestling on the floor, when her arm swung round and hit me across my face with such force it brought tears to my eyes. "I'll do you," I exclaimed meaning I would smack her back.
"You wouldn't know how to," Margaret replied and quickly ran up the stairs.
I dashed after her taking up the challenge. When I got to Margaret's bedroom there was no sign of her but a low cough came from my mother's bedroom. I looked in and there she was laying on the bed with her knickers already off. The penny dropped, she wanted me to fuck her. Looking at her naked cunt with just a light covering of rich black hair covering it was mesmerizing.
"Now come and do me," she said.
I could hardly believe what I was seeing and hearing. Needless to say, me being a very horny young man and not being one to disappoint a lady was eager to oblige her and jumped onto the bed. I proceeded to strip off the rest of her clothing. At that time she wore no bra so her tits came into my immediate view. I was amazed how big and hard her nipples had grown. Gently taking hold of one of her breasts I started slowly massaging it and tweaking the nipple, then I began sucking it.
My lovely sister started to moan softly in my ear and was telling me to keep sucking her tits and to put my finger in her cunt. Always ready to please my dear sister I did her bidding. I slid my finger along her cunt lips feeling for her love box. We started into a frenzy of lovers kissing grappling tongue against tongue. She had become very wet between her legs so when I found her hole my finger slid in very easily, then two fingers. After ten minutes or so I finally managed to get three inside her now constantly dripping cunt from which I started drinking her juices like it was a fountain head.
She was squirming around on the bed, making it difficult to hold on to her without hurting her, so I lifted my body on top of her. My cock had become extremely hard during our writhing on the bed and was pressing hard against my beautiful sister's body. She took hold of it and started to stroke it, then to my amazement she turned herself and put it into her mouth and started to suck on it, Wow!! This was unbelievable. I was in heaven!! It was not long before my spunk was shooting down her throat, one spurt, two spurts and then a 3rd it was fantastic.
After resting for a while I laid my leg across her. Soon my cock was starting to stand to attention. I very quickly got a full and very hard erection. Margaret took hold of it and guided it into her wet cunt where it slid in without any trouble. I started to fuck her very slowly, thrust in 1, 2 out 3, 4 in 5, 6 out 7, 8 in 9, 10 then in 1 out 2 in 3 out 4 in 5 out 6 in 7 out 8 in 9 out 10 up a gear in, out, in, out, in, out shake it all about my god!!! It was a glorious fuck.
Margaret, my darling, was bucking so hard she almost threw me off a couple of times. Her breathing was getting harder by the minute. She started shouting so loud I thought the entire street must have heard her.
"More, more, give me more of your cock. Harder fuck me harder. I want every inch of your cock in my cunt. Fill me up; make me cum, shoot your spunk into me!"
