All persons engaged in sexual activity in this story, are over 18 years of age.
This story took place in the 1970s in the United Kingdom when the 'World Wide Web' or Internet as it is known today, was barely an infant and not available to private individuals. As for mobile phones, they were only at an experimental stage. This meant that knowledge of sex was gleaned mostly by looking at adult magazines aka Playboy, Penthouse, Hustler and so on.
Boys and girls were nowhere near as mature or knowledgeable about sex at age 18 compared to many of today's 14 or 15 year olds, thanks mainly to the multitude of internet 'information' that can now be accessed by anyone that can type 'sex' into a search engine.
All of this is to set the scene for you, to make you aware that in the 1970s, unlike the present, many boys and girls at age 18 were considerably naΓ―ve when it came to real sexual encounters.
*****
I am Ben and I lived with my sister Susan and our parents, just like most of our friends, in one of the smaller cities in England. At 19 and a bit, I was the oldest child, my sister at just 18 was only fifteen months younger. I don't know whether our parents deliberately had two children so close together or whether it just happened, but we grew up as friends, perhaps that was the idea.
We lived in a modest semi-detached house, two rooms and a kitchen downstairs and three bedrooms and a bathroom upstairs. There was a small front garden and then about 150 feet of garden at the rear, the width of the house. Very similar to most of the houses in the neighbourhood.
The one addition that we had at the end of our rear garden was a reasonably sized, wooden shed. It originally had been used by our father for his hobby of woodworking and to store various garden tools.
As we grew up, we had lots of local friends, boys and girls, and as long as we didn't mess with his woodworking tools, we were allowed to play in the shed. Over the years it had been a fort; a cabin in the woods, a post office, a store, a school...well you get the picture, it was the focus of our play.
I was currently attending college to study engineering and since Dad had got fed up of woodworking as a hobby a few years ago, I had more or less taken over the shed. Unlike my small bedroom, it was a quiet space away from the house, where I could mend or take things apart to see how they worked and leave them on the workbench, knowing that no one would clear them away or move them. I had watched my dad using his tools and learned how to do some basic woodwork, so I had enough skills to keep the shed waterproof and draught free.
When my parents changed our old living room suite, I had begged one of the old comfortable armchairs. When I told them that it was a place where I could read my text books away from the distraction of the TV and family chatter, they were pleased to hear I wanted to study and I had installed it in one corner of the shed. I even had an old paraffin heater that made it really cosy on cooler days and evenings.
What they didn't know was that it was also an ideal place to store and read the small collection of top-shelf, adult magazines, that I had been buying from a newsagent near the college. I had fashioned a false bottom to a couple of the deep tool draws under the workbench to store them in and unless you knew the secret, they were almost undetectable. There was an old tree in the centre of the garden, about 50 feet from the shed, that hid the shed from the upstairs windows of our house and from any of our neighbour's windows. From the armchair, I could just see through the window that faced the house if anyone should venture down the path, but all anyone could see of me, was my head. I spent many happy hours 'studying' with a tissue, looking at female anatomy and reading the accounts of sexual exploits from the 'letters' pages and short stories. This was how I had gleaned my scant knowledge of sex.
It was a warm afternoon, during the short half-term break from college, my sister was training to be a hairdresser so worked most days in the salon, and my parents also both worked, so I was alone for the afternoon.
I had been busy getting ready for mid-term tests and hadn't found time to read the latest magazine yet, so this seemed a good opportunity to have some 'alone time' in the shed.
I had got comfortable, retrieved the magazine from its hiding place, and was getting myself gradually aroused reading the articles and seeing the pictures of the naked and voluptuous girls, none of whom were shaved back then. All you could usually see in the photos were bare breasts and a triangle of dark hair with just a hint of a slit, but it was more than I had seen in real life. Knowing I was going to be alone for a few hours, I undid my jeans and slipped them down my legs along with my underwear. It felt sexy to be naked from the waist down and of course gave me better access to slowly stroke my cock.
'Mmmmm' I thought, running my fingers over the head of my cock, 'I'd love to feel what it's like to have my cock in you', I daydreamed, as I looked at a more explicit photo of a model who had much sparser pubic hair than the others and her slit was clearly visible.
I was so engrossed that I hadn't bothered to look out of the window for a while. It was only when the light sort of changed, that I looked up. There was Susan, my sister trying to look through the window.
"Ben," she shouted, "are you in there?"
Panic!
I wasn't sure how much she could see inside the shed, it was sunny outside, and the glass was probably acting like a mirror, but I couldn't be sure. I didn't reply. I tried to pull up my underwear and jeans without standing up, forcing my rapidly softening dick into them. My hands were shaking, and nothing seemed to want to go where it should.
"BEN," she shouted louder, "I can see something moving, so I know you are in there. Let me in, I left my house key inside this morning and the house is locked. I want to borrow the spare one we keep in the shed."
I had taken the precaution of fitting a bolt to the inside of the door for 'privacy', so I knew she couldn't get in. "I'm...I'm just coming," I finally shouted, oh the irony.
I saw she had moved round towards the door, so as quick as I could, I stood up and managed to get my clothes in order.
"Come on Ben, for goodness sake, what are you doing in there?" she was getting cross now.
I slid back the bolt and felt her push the door towards me.
"Sue," I said, "why aren't you at work?"
"Because Ben, if you had half a brain you would know it's Wednesday and my half day."
Damn, because I am usually at college, it had slipped my mind that she worked on Saturdays, so she got a half day on Wednesdays.
"Oh, errr...yea.. sorry I forgot," I came up with.
She barged into the shed, "So what took you so long, don't tell me you were studying during the holiday," she said sarcastically.
"I was just..emmm.. just... dozing."
"Dozing?"
"Yea, its kinda warm in here," I improvised.
"Hmm, you are quite red, and it smells bit funny too," she said, sniffing and looking round.
Shit, Shit, I hadn't had time to put the magazine away, although it was face down on the workbench.
"Let me have it then."
"Have it?" I repeated, stupidly.
"The key Ben, the key. Oh, I'll just get it myself, you are still asleep I think," she said, and started to reach past me over the workbench to the nail where the spare key hung.
"Oh, what's this?" she asked, spotting the glossy magazine and picking it up.
"It's just...emm.. something I err.. borrowed... from a friend.. a mate that is." I said, making it up as I went along.
"Eww," she said, turning it over, "this is one of those mucky mags isn't it?"
Caught red handed, I was blushing even more, "Well...it's ummm...sort of educational really," I said, flustered now at being found out by my younger sister, who was acting more like my mom.
She put her handbag down on the workbench and opened the magazine.
"I've never looked through one of these before," she said, flicking through the pages. "Oh Lord look at that, and that," her voice rising, "is that real," she said, stopping at the photo of a young man in tight underwear, sporting an erection, although it was covered, it left nothing to the imagination.
"Let me have it back," I said, embarrassed at seeing her ogling the guys.
"Not yet," she paused, "wow, I didn't realise they could print this," she said, more quietly almost to herself as she turned over a few more pages.
She was wearing a thin, low cut, short sleeved, top that showed the tiniest bit of cleavage, and I could see a red flush starting from around there and moving up to her neck, as she studied page after page.
