My wife and I had been out with Catherine and Pete and during the evening I had offered to move some rubbish from her garden when I took some of my own to the tip.  Catherine said she would call me if she wasn’t going to be in and leave the gate open for me.  We swapped numbers.  The next day I moved the rubbish and had a chat with her.  I had known Catherine since she was thirteen and she was now in her mid-thirties.  In my opinion she had got better looking as she had got older.  She had transformed from a shy skinny girl to a well-built woman.  The curves were all in the right places.  We flirted a little as we always did and then I was on my way to the tip.

It was about a week later when I was sat at work on a late shift.  Suddenly there were four pings on my phone.  Straight away I could see it was from Catherine and opened WhatsApp to see what she wanted.  Well, you could have knocked me down with a feather.  The first photo was a woman in her black underwear.  The head was deliberately cut off, so I couldn’t say that it was definitely Catherine.  The second shot changed that as it was a frontal shot still in her undies but with her face showing a big smile.  The third shot had her tits out.  Boy had she grown since she was thirteen and flat chested.  I judged her to now have a 36DD bust.  Then the last photo had her totally naked.  I clicked on the photo so I could zoom in on parts of her.  Besides her large nipples she also had a well-trimmed patch of pubic hair and long dangly pussy lips.  Finally, there was a message that just said, “see you later lover.”   It caused me a serious problem in the trouser department.  I wondered what she meant about see you later as it was Friday and my wife and I were due to see them Saturday night.

I contemplated taking a selfie of my hard cock and sexing it to her but decided not to.  All evening my thoughts kept returning to the photos and her message.  When I got home my wife got a good shagging due to me being worked up all shift.  Mind, she wasn’t unhappy about that, and asked what had got me so worked up.  I told her it must be spring and that time of year.  That evening we met up with Catherine and Pete.  There was the usual banter between us, but no clue about the photos.  Later I got a few moments alone with Catherine and told her I loved the pictures.  Catherine asked what pictures.  I told her the ones of her in her black undies or not in the later two.  Suddenly Catherine was bright red.  We couldn’t talk further as Pete and my wife were returning.  Pete immediately asked Catherine if she was alright.  She told him she was suddenly rather hot and needed to go and get some fresh air.  I offered to keep her company.

Outside the club Catherine asked that I never showed the pictures to Pete and told me that she had sent them to the wrong person.  I assured her that I had no intentions of showing them to anyone else and asked who they were meant for.  Catherine told me that she had met a man and had fancied a fling with him and thought that she had sent them to him.   She said that explained why he never answered.  I told her that I was happy to stand in for him.  I think it dawned on her that all these years of flirting and the banter I had actually fancied her.  Ring me Monday she told me just as Pete came out to see how she was.  She told him she was feeling much better and the three of us went back in the club.

On Monday I waited until my wife had gone off to work and the kids off to school, and Pete and the kids would also be out when I rang her.  Catherine was trying to roll things back, but I wanted to take things further and asked if I could come round.  Catherine told me just for talks.  I was round there in minutes.  Right from the start I made it very clear to Catherine that I wanted to make love to her.  Catherine tried to guilt trip me reminding me that I am married with kids, I reminded her that she was more than ready to have a fling with someone else she hardly knew, and she was married with kids, and besides I had fancied her for years.

I moved in and took her in my arms and kissed her sliding my tongue into her mouth.  As we broke the kiss Catherine groaned and then said, “OK but it is only going to be a one off.”  I agreed knowing full well that these things are never just a one off.  Catherine led me to her bedroom where she allowed me to undress her.  I was kissing her as I undid and removed her blouse.  I broke the kiss so I could see her 36DD’s come into view as I removed her bra.  For years I had fantasised about getting to grips wither tits and now I had one in my hand whilst my mouth sucked the nipple of the other into my mouth.  Katherine groaned again as I worked her on her plump tits.  Katherine had decided that she wanted to get involved and was undoing my belt and then fumbling with the zipper.  To prevent her ripping my trousers I stopped my assault on her tits and lowered the zip for her.  Then I was back playing with her tits.

Catherine soon had my cock out and was stroking it as her other hand was holding my head to her breast.  My cock was rock hard as Katherine stroked it.  Then she was pushing my head from her breast.  I thought for a moment that she had changed her mind and perhaps I would be on my way very frustrated.  Catherine dropped to her knees and looked at my cock as she stroked it.  She suddenly announced that my cock looked completely different to Pete’s.  I later gathered that his is uncircumcised where mine had the chop while I was very young.  Then her tongue slipped from her lips and gently licked the head.  It was my turn to groan as the licks kept coming before she finally opened her mouth and took about a third of my cock into her mouth.  Catherine tried to say something, but I couldn’t comprehend what was said.  Katherine removed it from her mouth and declared that it was bigger than Pete’s she added that it was not only a bit longer but also thicker.  I laughed, “All the better to fuck you with.”  Catherine laughed as she put it back in her mouth and took almost half of it in her mouth and then started to bob her head up and down on it.

I stood groaning with my hands gently on her head as she worked my cock over.  Then she took a big breath and tried to get as much as she possibly could into her mouth.  I was impressed as she took more than my wife can and more than any of my girlfriends ever could.  Before you feel intimidated, I don’t think it is that big at seven and a half inches long, but it is pretty thick.  Catherine gagged and took it out her mouth and I took the opportunity to lift her back to her feet.  I wondered if Catherine had worn slacks to slow and prevent me from getting to her panties, but it was my turn to be on my knees as I pulled them down as she lift her feet one at a time to allow me to remove them and her slippers.  I kissed Catherine’s mound which was still hidden in her panties.  I felt he shiver as she felt me touch her there.  Then I hooked my fingers in the waistband of her panties and slowly slid them down over her arse and down her legs. I got the around her knees and stopped as I bent forward again to kiss her mound and her trimmed pussy hairs.

Catherine tried to part her legs to give me access to her pussy and nearly fell over as her panties were still around her knees.    It broke the ice and had us both laughing.  It seemed an easy step from there to getting totally naked and ending up in a sixty-nine position with me licking and sucking Catherine’s pussy while she worked her magic on my cock in her mouth.  I warned Catherine that I would come if she kept sucking my cock.  That just made her suck even harder and capture all my cum in her mouth.  She made a point of showing me that she swallowed my load before going back to sucking my cock.  Just a few moments later Catherine gagged then groaned as her body shook as I tongued her clitoris.  I hoped that would be her first climax of many.

Starters out that way I was looking for the main course and just as soon as Catherine decided I was hard enough she rolled me onto my back and slid her pussy down my pole.  I was surprised just how tight her pussy was considering she had three kids.  It took her a few thrusts to get it all in ant which point she sat upright and went “Whooo that’s thick.  I fell like I’m about to split down there.”  I told her it felt pretty damn good from where I was.  Then Catherine started to ride me as she remained upright which made her tits bounce.  They looked bloody marvellous from where I was, and I just had to reach up and hold them as they shook around.  Catherine rode hard and brought herself off.  I pumped her from below for a few more moments before coming in her.  Starters and mains out the way, there was just time for the sweet before Catherine told me she would have to collect her kids.  That suddenly brought me back to reality and what we had been doing, and I suddenly felt quite guilty at cheating on my wife.

I know I should have kept it to myself, but I felt so guilty that I sat my wife down and told her I had something serious to talk to her about, she looked worried until I told my her what we had done.  My wife suddenly looked relieved and then confessed that she had slept with Pete a dozen or so times over the years.  Now that it was out in the open my wife talked to Catherine about it and the following weekend, I took Catherine home whilst Pete took my wife home.  This went on for three years until the Virus struck and isolations hit us.  The minute the isolating stopped we had our first swap again.  Pete has asked the next time we swap can we all do it in the same room.  That will be a first for us as we have always swapped in different houses.  I can’t wait for it but Catherine has some reservations, but we will see.
