All persons engaged in sexual activity in this story are over 18 years of age.

The first three chapters were based on a real event that happened in 1969, that is burned into my memory, when, bear in mind, there was no internet where anyone could readily obtain information as you can today. Only the detailed descriptions have been embellished to make a more readable story (my memory isn't that good).

Reading these previous chapters may give you a better insight into the story background, as time has now moved on a considerable number of years.

There is an element of cheating and swapping in this story, so if you don't agree with that, you don't have to read it, otherwise, enjoy.

Ch 6

It was another very warm day, about three weeks after Jayne and I, accompanied by her sister Sarah and Rob, had been to 'that' party. When we had returned home, both my wife and Sarah's husband had been very inebriated.

That evening had evolved into spontaneous and unexpected sexual activities that only Sarah and I remembered, which we had agreed to add to our small list of 'secrets' that we held between us and is detailed in the last chapter.

I was sitting out in the garden in just a T shirt and shorts, with a morning cup of coffee and reading a newspaper, while enjoying the warmth of the sun.

"Sarah's got a problem," my wife said, coming out into the garden, having just come off the phone with her sister.

"What sort of problem?" I asked, my guilty conscience already making up bad scenarios.

"There's water dripping from under the basin in the bathroom and Rob is away until Monday at some conference up north."

"Can't she just put a bucket under it for now," I said, relieved but aware that her problem could soon become mine.

"She has of course," Jayne said, a little testily, "but she is worried that it might get worse and flood the bathroom."

"How about a plumber?"

"It's Saturday isn't it, not only would it cost a fortune to get an emergency call-out at a weekend, but I doubt we could even find one available," Jayne said.

I noticed the change now to 'we'.

I knew where this was going, and as I am a practical guy and had done lots of plumbing work in our own home, and we were family after all, I thought I would earn a few 'brownie points' by volunteering before Jayne asked me to.

"So, do you want me to go round there and see if I can do something?" I asked, standing up slowly.

"Oh, would you, that would be the nice thing to do and perhaps I might reward you later," she said, coming over and hugging me, pressing herself against me.

I reciprocated by putting my arms round her, my hands on her firm bottom and pulling her closer towards me. My cock immediately reacted.

"Oh no," she said gently, beginning to push me away with a twinkle in her eye, "after, not before."

"Hmmm," I said, as I reluctantly released her.

"I tell you what, it's such a nice day, I'll and come with you and bring the children, then I can look after their cousins too so that they are not under your feet while you see if you can sort something out for Sarah."

"That sounds like a plan, perhaps you can take them all to the park just down the road, they can let off some steam, so they are tired later," I said, winking at her.

"Yes, maybe," she chuckled.

"How about you ring your sister back while I go and find some tools and bits and pieces that I might need."

"OK, and thank you," she said, returning to the house.

I wandered off to the garage and filled my toolbox with everything I thought I might need, not sure what might be at Sarah and Rob's house. I knew he wasn't much of a 'do-it-yourself' man, and probably hadn't got much in the way of plumbing tools or spare bits and pieces.

By the time I had done that, Jayne had the children ready, who were excited at the unexpected visit to see their cousins. Being a warm day, none of us were wearing many clothes, mostly T shirts of assorted colours, and shorts.

Jayne looked good in her mid-thigh denim shorts, with her long legs, tanned from often being out in the sun. After having two children each, the two sisters still visit the gym regularly together, keeping their bodies in trim. As I have mentioned in previous chapters, Jayne has a slim figure, with smaller breasts than red-haired Sarah, who has fuller figure, but both of them look fit and several years younger than their actual age.

It didn't take long to drive to Sarah's, and as we pulled onto the drive, she opened the door of the house and our two children were quickly out of the car to go and see their cousins, leaving us adults to get out with a little more decorum.

"Hi Sarah," I said, giving her the usual kiss on her cheek, followed by Jayne doing the same.

"Thanks for coming over," she said, looking a little worried.

"It's no problem," I said, casting my eyes over Sarah's skimpy tight top and short flowery skirt. It was clear she hadn't bothered with a bra as I could see the soft outline of her nipples under the top.

"We've made it into a little outing for the children, and I'll keep an eye on them all while Pete sees what he can do," Jayne said.

"Oh that's great," Sarah replied.

Sarah rarely missed anything and had seen me eying her up and gave a small enigmatic smile before inviting us into the house.

"So, what's the problem?" I asked, once inside.

"It'll be easier if you come and take a look, it's a leak of some sort under the basin in our en-suite bathroom."

"Go and have a look, then come and tell me what you think," Jane said, "I'll take the children out into the garden."

"Right, lead on, Sarah," although from the many previous visits, I knew where it was, but I had never been into their bedroom before and it felt like a personal space I needed to be invited into.

Sarah went up the stairs with me following. The higher she got, the more of her thighs I could see under that short, loose, skirt. I slowed down and let her get another step ahead of me and it was then I caught a flash of white lacy knickers, hugging her bottom. At that moment, she turned and glanced back...damn, caught again.

"Incorrigible," she said, quietly, with a grin, and continued up the stairs to the first-floor landing.

She led the way into their bedroom, all neat and tidy as if no one ever used the room, then into the attached bathroom.

"It's under here," she said, crouching down and pointing through the doors of a small floor-standing cupboard with a basin inset into the top.

I was tempted to get another eyeful as her skirt had ridden up her thighs, but having just been caught I decided to concentrate on the problem.

I could see she had indeed put a small bucket under the leak, and it was slowly being filled by a constant heavy drip of water.

"I'll have to go and get a torch so I can see what's going on," I said.

"I've got one here I was using, but it's very awkward to see under there."

As with most of these units, you have to squeeze in on your back to be able to look upwards under the basin at the connections to the tap. I moved the bucket out of the way and prepared to get wet as I didn't want to turn the water off at the mains until I had seen where the leak was coming from.

I took the torch off her and lying down on the floor, slid my shoulders into the base of the unit. As I expected I started to feel the drip of chilly water on my chest.

"Sorry, you're going to get very wet," Sarah said, crouching down to look into the unit.

With her knees pointing towards me, it was very distracting, as now I had a clear view right up her skirt to the lacy white knickers I had glimpsed earlier. However, the constant drip of water on me focussed my attention on seeing where the water was coming from before I drowned.

"Ahh, I can see it," I said.

Sarah giggled.

"It's the flexible pipe connected to the tap that's leaking," I said, ignoring Sarah's laugh at the interpreted inuendo.

I realised that she knew exactly what she was doing crouched down there.

With a bit of effort, I struggled back out, forcing Sarah to move out of the way.

"Oh goodness, your T shirt is soaked," she said, stating the obvious.

"Yes, it's a good job it's a hot day and not winter," I replied, "I'd better go and turn the water off now that I know what the cause is."

"Can you fix it?"

"Yes, I think so, but it's a bit tricky, I'll go and get a few things from the car once the water is off," I said, "can you put the bucket back for now."

Having found the stop-tap in the kitchen, I went out to see Jayne who was happily sitting in the sun in the garden watching the children playing together.

"Good Lord, you look as though you have been bathing with your clothes on," she said, grinning.

"Yes, it's a wet T shirt contest," I quipped, "it's you and Sarah's turn next."

"In your dreams," she laughed.

"This is going to take a while, probably about and hour or so, do you want to stop here or take the children to the park?"

"Oh, if it's going to be that long we'll walk down to the park and come back later," she said, getting up and preparing to gather the children together, "oh, and you might want to take that shirt off and put it on the washing line here to dry in the sun," she added.

I did as she said and then went out to the car to get the tools and a new flexible pipe, which I had brought just in case, that I hoped would fit.

As I went back to the house, I passed her with the children, carrying some balls and a couple of tennis racquets heading for the local park.

"Have fun," I said.

"You too," she responded, laughing.

'I doubt it', I thought.

Sarah was still where I left her, but the water had now stopped dripping.

"Oh, I like the new look," she said, seeing my bare upper half and quickly running her hand through my chest hair.

"Errr, lets not start anything," I said, removing her hand, "Jayne suggested I hang my shirt out to dry, and she has taken all the children down to the park for an hour or so, while I sort this out," I said.

She looked thoughtful and had a strange look on her face, "So, it's just you and me here now?"

"Yes, I guess so," I said, removing the bucket and then lying down to get back under the basin, to change the pipe.

"Can you pass me that long spanner thing and the new pipe please," I asked her once I was in position.

She again crouched down to pass them to me, giving me another show.

"Right, now can you hold onto the tap while I unscrew the old pipe, please?"

There was a pause as she stood up, then, "Ok, I'm doing it," she said, and had put her feet either side of me at the level of my hips. Now I had an even better view up her skirt as she had her legs apart.

I thought, 'this is going to take much longer with this distraction' but began to carefully unscrew the old pipe.

"Pete..."

"What?"

"I have wanted to ask something."

"Ok?" I grunted, as I struggled with the awkward connections.

"I was wondering... whether Jayne ever said anything about the night of the party, you know, when we did a few things afterwards?"

"Umm...no, I don't think she remembered much about it. Why?"

"You know me, I was curious to know if she had remembered any of it."

"No, why, did Rob say something?"

"Oh no, he hardly remembers going to the party, he was so drunk," she chuckled.

"Oh good, that's a relief," I said.

"It was fun though, wasn't it?"

"Yes, but a bit risky though."

"That makes it more exciting, doesn't it?"

"Maybe," I said, "but we were also a bit drunk too, otherwise it probably wouldn't have happened."

I was wondering where this conversation was going.

"I mean, seeing, hearing and feeling you having sex with Jayne that night without her knowing was really sexy, I keep thinking about it," she continued, along the same line.

Remembering that she had surreptitiously sucked my cock while I was eating out a drunken Jayne, and then actively helped to push my cock into Jayne, without her knowing, had my cock growing in my shorts at the memory.

"Well, I didn't know you were going to do that, I thought you just wanted to watch like that first time."

"I was, but then I saw the opportunity and just went for it," she chuckled again.

"It was a bit of a shock and a bit naughty," the memory stirring my cock even more.

"But I can see by the reaction in your shorts now, that you liked it, and you're thinking about it."

"I admit it was very erotic, but I think you're taking too many chances and..."

Although she still had hold of the tap on top of the basin, as I tried to get the spanner into the constricted space underneath to undo it, I glimpsed and felt her knees coming down to the floor so that she was kneeling with her legs either side of me.

"What are you doing?"

I soon discovered, as she lowered her body so that her clothed pussy landed right on what was now an almost full erection.

"Mmmm," she purred.

"No Sarah, we can't, Jayne will be back soon, and I won't be able to fix this if you do that, and you'll have no water."

"I'm sure you can multi-task," she said, sliding slightly back and forth.

My cock thought it was a great idea as it was now fully hard, but my back and shoulders were beginning to hurt from the position I was in.

"Sarah, you really need to let me finish this," I said, more sternly.

"Hmmm, ok then spoilsport," she said, slightly grumpily, and stood back up.

After about twenty minutes and with a bit more twisting and turning in the confined space, I eventually managed to replace the pipe. After checking, with the water back on again, that all was well, I went back upstairs and began to pack away my tools in the bathroom.

"Thank you," Sarah said, "it's a relief to know I am not going to wake up to a flooded bathroom and besides, I am sure you have saved me a lot of money."

"No problem, I'm glad it was something relatively simple." I said, lifting my shoulders up and down to ease some of the pain and tension in my muscles.

"Have you hurt your back?"

"No, it's just cramped a bit from laying under there for so long."

"Turn around, let me see if I can free them a bit."

"No. it's fine, it'll be ok in a minute or two."

"Just do it," she said, probably like she would to one of her children.

With a huff, I did as I was told and felt Sarah's fingers begin probing my taut shoulder muscles.

"Oww, that's sore," I yelped, as she dug her fingers in harder.

"I hardly touched you. Come and lie down on the bed for a moment and I'll have a proper go at loosening them."

"Hmm, ok, but not too rough," I said, heading into their bedroom and laying face down on the bed.

"Don't be such a baby, no pain no gain," she said, unsympathetically, as she followed me and got onto the bed, sitting herself astride my bottom.

I could feel her warmth on me as she leaned forwards and began to manipulate my shoulder and neck muscles with long sweeps of her hands.

"We could have done with some massage oil, but you'll have to put up with just my hands for now."

"That's ok, what you're doing is just fine." I said, beginning to feel my muscles respond as she gradually pressed her fingers in harder, searching out the knots in them.

As the tension diminished, I began to feel other sensations from her warm thighs either side of me, and whatever part of her that was rubbing along my bottom as she moved. Knowing she only had on a short, thin, skirt, I surmised that her knickers must be directly against my shorts. My cock responded to the thoughts by beginning to grow again.

After about 10 minutes of this, with my cock now fully erect under me, I felt my back beginning to get sore from the friction of her hands and fingers directly on my skin.

"I think that will do for now, my back is getting a bit sore."

"Well, you'd better turn over then, I need to release the tension along the top of the front of your shoulders," she replied, lifting herself up onto her knees.

"It's ok," I said, aware of the state of my cock, "I think I'll be fine now, thanks."

"Are you being a baby again, just turn over for goodness sake," she insisted, in that mother-like voice.

'Oh well', I thought, 'it won't be the first time today she has felt it ', so I turned over to lie on my back, looking up at her.

She plonked herself down, right onto the length of my cock.

"Ohhh, I see," she grinned.

"Yes, sorry," I said, a bit embarrassed.

"Oh, don't be," she said, her eyes sparkling, and experimentally she slid up and down a few inches.

"You know what, I think you deserve a reward," she said quietly, rubbing her hand over my bare chest and pinching a nipple on the way.

Jayne had already promised me a 'reward' and with Sarah in this mood, I had a good idea what she had in mind.

"This is not a good idea, we don't want to do anything that might jeopardise both our families, do we?"

"No, of course not, but we do share a special bond, and a few secrets don't we, and although it was a long time ago, I often remember the things we did, and that you were my first," she said, somewhat wistfully. "I told you before, I sometimes think of those times when I'm with Rob and it always makes me come much harder."

"I know you did, and I told you I do too. You are an attractive woman, but Jayne will be back soon with the children."

"Would there be time for just a 'thank you' kiss then," she whispered, sexily, pressing her mound down hard against me and looking at me with those green eyes of hers.

I was nervous about the time, but she had got me excited, and I could smell and feel the warmth of her body against me. My cock twitched. I thought that even a long kiss wouldn't take too long, and from previous experiences, I did enjoy the way she kissed. I was rapidly losing my resolve.

It may sound odd, but I did feel a bit awkward being like this in the private space of their bedroom. However, Sarah didn't seem to have such qualms and quickly moved her head down towards me so that her lips were close enough for me to feel her warm breath on my face and her covered breasts touching my bare chest.

"Thank you," she said, quietly, before closing the gap between her lips and mine.

I said she was a good kisser, and within seconds, her tongue was probing past my lips into my mouth while in turn, I automatically put my arms around her.

As our tongues began to explore each other, I held onto her more tightly and I could feel my cock pressing against her through her thin knickers.

She shuffled her hips around until she managed to position my cock where she wanted it, in the 'V' of her thighs.

She broke our kiss to take a breath, "This brings back memories, feeling you against me like this," she whispered.

"Lots of other things have happened since then though."

"I know, but it all comes back to when we did this," she said, sensually grinding her body against me.

"I know, and it seemed harmless, but look what happened afterwards."

"You don't regret it, do you?" she asked, with a hint of seriousness.

"Does this feel like I did," I responded, copying her actions so that my hard cock moved against her in time with her own movements.

"Mmmm, no, I guess not, it feels really good, doesn't it?"

I had to admit that through our thin clothes, I could feel the head of my cock sliding against the soft part of where I knew her pussy would be, and it felt very sexy to be sort of dry-humping her in this way.

When I looked down, I could see that her nipples, erect now with her obvious arousal were tenting her tight top and just asking to be touched.

My excitement was such that without thinking any further than the next minute, I raised my left hand and placed it over her left breast and began a gentle massage, catching the hard nipple with the palm of my hand as I moved it around her medium sized breast.
