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 chats with 'experienced' friends or 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 naïve when it came to real sexual encounters.
Obviously, if you have read the previous chapters you will be more in tune with the characters.
**********
I had been back at college since Monday, and although I had tried to concentrate on the lectures and work, my mind kept going back to last Sunday afternoon and all that had happened with my sister Sue.
At my sister's suggestion, we had showered together while our parents were out for the afternoon. In the shower, we had given each other oral sex, the first time for either of us and both of us had intense orgasms.
Just before we left the shower, my sister had surprised and almost shocked me by making me stand still and not speak, then carefully and slowly, put the head of my cock just into her entrance for just a few moments. She said that she wanted to feel what it might be like if we went 'all the way', but then asked me if I would, and to think about it.
I thought about it a lot.
We had come a long way down the route of finding out a lot about sex with each other in secret, mainly in my shed, but to actually go 'all the way' with my sister, I wasn't sure. We had touched, stroked, and pleasured each other, eventually being naked together, but this was the biggest step, and although the thought of having my cock right inside her, gave me an erection every time, I didn't know if it might change everything afterwards. Then there was the risk of pregnancy or our parents finding out.
Yes, I was doing a lot of thinking.
One thing she had said was that I might need to 'buy something' and I worked out she meant a 'french letter' or 'Durex'. (I think that was the only brand name for condoms then, and they were often referred to by that name). I decided that to be on the safe side, I should buy some, even if it was only to be safe if we repeated some of the things we had already done, when my cum had ended up near her pussy. I could hide them in the false bottomed drawers in my shed, with my magazines, so keeping them hidden wasn't a problem.
Buying them in that era, was only from either a Chemist or a Barber Shop, but you had to ask for them. One problem was that you didn't want to buy them from anywhere where you were known, or where your parents might shop or get a haircut. Also, most chemist shops had female counter-assistants and usually only the owner or pharmacist was male. You couldn't just walk round any supermarket and slip them off a shelf into your shopping basket as you can now. Many young men had collections of toothbrushes and other small items, bought in place of Durex, when a young woman came to serve them at the counter and their courage failed them.
I was no different, and in my lunch times, I wandered the various streets looking for an anonymous chemist shop with a male serving at the counter. I reasoned that at lunchtime, the counter-assistant might go to lunch and the pharmacist would be serving at that time.
The first one I tried looked hopeful and the shop was empty when I walked in ready to ask for them. Unfortunately, the pharmacist must have been preparing something in the back room, and by the time he came to the counter, two of the young girls from college that I knew had come in and queued behind me. I blushed a little and bought a small packet of aspirin, then left. That sounds odd now, but that's how it was.
It took several days before I finally managed to walk out of a chemist shop with three Durex discretely placed in a brown paper bag. It was strange having them there in my pocket during the afternoon classes. I had bought my first packet of Durex, but would I have the courage or even the opportunity to use them.

It was the usual practice at home for either Sue or me to wash the dishes after our evening meal. There had often been arguments to determine who's turn it was, because one of us had perhaps mowed the lawn, or hung out washing, or done another chore that made it the others turn, However, since Sunday afternoon, we had started to do the dishes together, while our parents went to the sitting room to watch the TV. This gave us the opportunity to be close and for me to have an occasional feel of some part of my sister. We couldn't do much, for fear of discovery, but it did maintain an intimacy and made us both randy, so that afterwards I often had to go to my shed for a wank, and I noticed Sue went to her room straight after.
Sue always worked on Saturdays, as it was a busy day in the hair salon where she worked, so it was a surprise when I finally surfaced at about 10 am dressed in my habitual shorts and tee shirt, to find Sue standing by the kitchen sink in her pajamas. They were just plain trousers and top, with some sort of flowery pattern on them that hid any shape she had, probably why she was allowed to wear them around the house.
"Sue? I thought you would be at work?"
"Yeah, I should be, but they phoned early this morning to say there had been a big water leak from one of the wash basins overnight and they couldn't open today. So, I have an unexpected day off," she smiled.
"Ah, ok, a little bonus then," I said.
"Yep, great isn't it."
"What you going to do with this free day then?"
"I dunno, my friends all work, so I'm catching up on a few chores, starting with some hand washing of a few more delicate items. It's a nice warm day, so they should dry outside ok."
"Where are the folks?" I asked.
"In the garden, look," she nodded at the kitchen window.
"They look busy."
"Yeah, something to do with a new vegetable patch, I think. I wouldn't let them see you or you will get roped in," she grinned.
"Oh yea, thanks."
She already had the kitchen sink full of soapy water and a few things floating in there. I walked over behind her.
"What you got in there," I asked, just out of curiosity.
"Just a few bits and pieces that can't go in the washing machine."
"They look like...underwear," I said, peering into the water.
She started to blush, "They are, I bought these silkier bits on a whim a few months ago, they are not my normal kind, but they do feel a bit special when I wear them," she answered, shyly.
"Ohhhh," I murmured, when she pulled out a very sexy pair of panties, much finer than the ones I had seen her in, "they look really sexy," I said.
"Thank you, kind sir," she giggled.
"Wouldn't mind seeing you in those," I joked.
"In them or out of them," she retorted, blushing a bit more.
"Mmmmm," was all I could say.
Imagining her wearing those skimpier items, had me feeling a bit randy and my cock was beginning to grow. I moved closer to her so that my cock was touching her pajama-clad bottom.
"Hey," she said, "Mom and Dad are only there look, down near your shed, they'll see." she blustered.
"They are very busy though aren't they." I said, pressing myself against her bottom.
"Ben, they will see."
