All persons engaged in sexual activity in this story, are over 18 years of age.
This story took place in the mid to late 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 people at age 18 were considerably naΓ―ve when it came to real sexual encounters.
Obviously, if you have read the previous chapters, you will be more in tune with the characters.

"Did you both have a relaxing time while me and your dad were over at your gran's house," Mom asked, as we ate our Sunday evening meal together.
"Yes, it was a nice relaxing afternoon," Sue replied.
"I saw that Sally had come over, I'm glad you are friends with her," Mom said, looking at Sue, "she is such a pleasant girl and always so well dressed. Are you going to see more of each other?"
For a change, it was my turn to smirk at Sue. She knew instantly what I was thinking that there wasn't much of Sally we hadn't seen -- and photographed.
"Ummm, maybe," Sue said, trying not to choke on her food.
Mom gave her a stern look, "If you didn't speak with your mouth full, you probably wouldn't choke," she said. "I think Sally might be a good influence on you, she seems very 'proper'," Mom continued, "it might curb some of your more 'tomboy-like' activities."
Sue didn't say anymore, probably because she couldn't, but just continued to eat.
I don't know how I kept a straight face, but I'm glad I did.
"And what about you Ben, what did you do this afternoon?" Mom asked, next.
"Aww, I just went round to my mate Tony's house to sort out a couple of problems on his motorbike," I lied, convincingly.
"You like motorbikes then?"
"Well, I like messing with them and the technical aspects, not sure about riding one," I said.
Mom paused as if deciding whether to say more, then, "I used to ride a motorbike you know," she said, matter-of-factly.
Sue stopped eating, her fork halfway to her mouth.
"Really Mom? You never mentioned it before."
"Oh yes," Dad said, unusually joining in, "your mom was quite a biker-girl in her day, she was the one with the transport that took us out and about, me riding pillion."
Sue and I looked at each other open mouthed, it was the last thing we might have imagined.
"Don't look so surprised," Mom said, a faint blush on her cheeks, "I was young once you know."
"Yes, but you riding a motorbike," Sue said, "I never would have guessed."
"I think I have some photographs somewhere, if you would like to see them," she offered, on the spur of the moment.
"Emmm, yea, we would love to see them," I said, as surprised as Sue at this admission. Perhaps there was more to our mom than we thought.
"Hmm, that reminds me Ben, I did ask you some time ago if you could take a few photos of me, like the ones you did of Sue," she said.
It was my turn to choke on my food, it was turning into a weird meal.
"Like th...those of Sue?" I stuttered, taking a drink of water to clear my throat.
I noticed Sue's face had gone a sickly white, surely Mom hadn't found the hidden photos I had taken of Sue and me. No, she couldn't have otherwise she wouldn't be so calm if she had, and wouldn't be asking me to take similar photos surely?
"Yes, when you first had the camera, you took some photos of your sister outside, to practice, remember?"
"Oh, those photos," I said, without thinking.
Mom gave me an inquisitive look, "What did you think I meant?"
"Nothing, I mean, I had forgotten that you'd asked, and they were the first ones, so not very good," I bluffed, trying hard not to blush.
"Well, you've had lots of practice now, so perhaps you could think about it?"
"Yes, of course, we'll work something out," I said, careful not to look at Sue, and feeling my rapid heartbeat slowing down again.
"Good," she said.
It seemed the subject was being dropped and we continued to eat our dinner.
I hadn't really taken much notice before, but as I surreptitiously looked at Mom, I could see that she was an older version of Sue. True, she wasn't as slim as Sue, but she still had a good figure, and I was trying to imagine her around Sue's age, astride a motorbike, but the picture wouldn't come.
"Penny for them Ben,"
"What?" I said, not realising Mom had noticed I was gazing into space.
"You seemed miles away, in your own world, I wondered what you were thinking about?" Mom said.
"Oh, sorry, ummm...I was just trying to picture you on a motorbike," I said, truthfully.
"I'm beginning to wish I hadn't told you now, but I will dig out those photos later and you'll see."
"Ok, that'll be...interesting." I said, and got on with finishing my dinner.
The rest of the meal went much like any other; a few comments about various things, but nothing significant or worthy of remembering.
******************************************
Later, as usual, Sue and I were washing-up the dinner things in the kitchen.
"Whew, that was a bit awkward," I whispered in Sue's ear, having looked over at the door to check no one was close by.
"It was a bit scary, I thought she knew something, all that talk about Sally and then about photographs."
"Just imagine though if she did want some sexy photos taken," I whispered, even quieter.
"Ben, are you perving on Mom?" she said, almost inaudibly.
"No, of course not, but..."
"You are, aren't you?" Sue said, a bit louder, turning to look me in the eye.
"No, well, not really, I mean, when Dad said about her being a 'biker-girl', I couldn't help wondering."
"It wouldn't be like today you know, all short skirts and flashing their panties," she said, a little too loudly.
"Shhh," I cautioned her, "they'll hear."
"Yes, sorry," she whispered.
"I know that, but she must have done some sexy things when she and Dad were younger...you know."
"Of course," she remembered to whisper this time, "remember when we were decorating my bedroom, we heard them 'at it' in their room, didn't we? So, they still 'do it'."
"Yes, I remember what we did while we listened too," I said, with a grin.
Still with her rubber glove on, she quickly moved one hand in front of me and felt the front of the jogging trousers I had changed into after Sally had left.
"Hey," I hissed, looking quickly behind us at the door.
"I knew you were hard," she said, quietly chuckling, "thinking about taking naughty photos of Mom has made you randy hasn't it. Go on admit it?"
"I never gave it a moments thought until today, but its just a fantasy, she would never do anything like that," I said.
"Hmmm, that didn't stay just a fantasy with me though, did it big brother?" she said, grinning ear to ear.
"Yes, but this is Mom we are talking about, it's even difficult to imagine."
"Looks like you've managed it," she said, taking a firmer grip on my now much harder cock.
"Sue, stop it, see what you've done now, not only is the front of my trousers wet from your glove, but you have got me fully hard, I hope no one come in."
"You shouldn't have been having those thoughts about Mom then, should you?" she quipped, in a whisper, and let go of my cock.
I glanced at the door, and listened for any movement from the living room where I could hear the TV was on. Confident all was clear for a few moments, I slipped quickly behind Sue, put my arms around her and my hands up onto her breasts, one in each hand, then pulled her back towards me, pressing my hard cock against the groove of her pert bottom.
"You just want me to have thoughts about you, don't you?" I whispered, right down her ear, and at the same time ground my cock against her.
"Ben, you stop it, you know we nearly got caught here last time," she said, struggling noiselessly to get free.
"You liked it though, and the danger?" I said.
"You know I do, but this is madness," she said, her breathing going a little faster.
"Mmm, so nice feeling my cock against you, isn't it?"
"I know, but not now, we don't want to spoil it by being caught, and anyway, I think Mom is going to look out those old photos, she may come past at any second," Sue said.
I realised she was probably right, and it wasn't worth the risk, so reluctantly I let her go and moved back by her side to finish drying the crockery.
