My Sister Sarah

My sister is just ten months older; my parents often joke I was there little surprise! My sister and I have always been very close and share almost everything, especially when we were kids. Due to the timings of our birthday’s we were in the same year at school, my sister was one of the oldest in the class, and I was the youngest.

Our relationship became complex when we reached twelve years of age. Our school dedicated some lessons the Sex Ed. When we got home, we spoke about what we had heard, we already knew about sex, but the details were intriguing. We both had penchants for the sciences and later in life would study science-related subjects to degree level.

After the lessons, we told each other that we had become aroused in class, and I admitted I wanted to see what the sexual organs of a female looked like, and my sister admitted to wondering what the male sexual organs would look like. When younger, we had seen each other naked and even been bathed together, but our parents were relatively modest and reserved, and we had been encouraged to cover up from a relatively young age.

Purely for the scientific interest, we agree to let the other look at our intimate sexual parts. My sister insisted I go first. I was nervous, but I took my trousers and boxers off and lay on the bed. It felt odd to have somebody else look at my dick, and when she touched it, I had an instant erection. She was fascinated by my erect dick. She gently pulled the foreskin back and felt the glans (bell end) which was very sensitive to her touch. She inspected my testicles (balls) in great detail. Her face and neck were quite red, and I wrongly assumed it was embarrassment; however, I now know she was also sexually aroused. She also played with my pubes and commented we had precisely the same colour pubic hair. I then asked if I could see her?

She still had her school uniform on and reached under her skirt, removed her black underwear, and lay on the bed raising her skirt My first thought was amazement and the mass of ginger blonde pubic hair she had; it was way more than I had. She was right, though; it was the same colour as mine. Nestled between all this growth was her pussy. She had has quite pronounced labia; at the time, I thought it looked like a Cornish Pastie. Sarah shuddered when I first touched her. I parted her pussy lips and marvelled at the opening to her vagina; I commented I found it hard to believe that a penis could fit in such a small opening. My sister said the thought of a baby’s head coming out of it worried her more! Next, I looked carefully at her urethra opening and her very pink clitoris. She openly moaned when I touched it she asked me to be very gentle when touching it.

Thus started our sexual relationship, and although we never actually had sexual intercourse over the next six years, we pretty much did everything else. She once got me to orgasm and took a sample of the sperm and put it on a slide for her microscope. We could see like blurred moving images; I think we needed a better microscope, though.

We would masturbate together, she would jack me off, and I would finger her. The oral stuff came to a lot later. We had both been to a classmate’s sixteenth birthday and had drunk quite a lot of alcohol. When we got home, our parents had gone to bed, and we had a session on the couch which ended up with us both in her bedroom. Sarah’s bedroom had two single beds and had initially been our bedroom. Our parents never suspected anything when I slept back in my old bed, having first been in my sister’s first!! After the party, she was jacking me off and just put my dick in her mouth. It was a fantastic feeling, and I did cum in her mouth, which shocked her.

We would often be nude in bed together in the sixty-nine position, which usually resulted in us coming. I recall being fascinated watching her ass pulsate as she came. The closest we came to full-blown sex was when I used to rub my penis through her labia. I’m glad we never went all the way, as I think that could have screwed us both up. We didn’t consider what we were doing was i****t as there was no actual penetrative sex involved.

On one holiday in Florida, our parents went out for the evening, leaving us in the villa alone. We ended us skinny dipping in the villa’s pool. In the end, we were in the water with me fingering her, and she jacked me off. I came into the pool. On another occasion, we all went to the cinema to watch Avatar. Our parents couldn’t get seats together, so we sat in the back row and our parents in the front. I was sat next to the wall at the back with Sarah next to me. Halfway through the film, I put my hand on her knee, she put her coat over her lap. Minutes later, I had my hand in her knickers, fingering my sister’s pussy whilst looking at the back of my mother’s head. That was the most dangerous it ever got.

We would often find a cornfield in summer and make out, usually ending with us both nude and having oral sex. On one of these occasions, I recall I had my head between Sarah’s legs licking her now shaved pussy, and a dog started sniffing my ass!! I jumped so much my nose almost ended up my sister’s vagina!! These sessions usually ended up with us both cumming out of our brains.

Our father worked and lived in London for a year and mum, me and Sarah were due to spend the weekend with him. Unfortunately, mum became ill with a heavy cold, so just Sarah and I went. It was early morning and there were only a few people on the train in our carriage. My sister had my cock out, jacking me off, and at one point, I was on my knees licking her pussy as she looked out for the conductor and anybody passing. On the train back the following day, it was nighttime, but more people were in the carriage. I had my hand down the back of Sarah’s jeans, feeling her ass, and that was the first time my finger went in her ass hole. We took so many risks that day!!

From around eighteen, we both got partners, and all our messing around eventually ended.
