M name is Neil. My wife, Di and I married young and we had 2 children by the time we were mid-20's. We both worked hard to establish ourselves, which didn't leave much time for sex, although we found what we managed very satisfying. Our experience of sex with other people was initially limited to an illicit snog or a brief fumble with someone else's wife/husband at a party or Christmas do, usually unbeknown to each other at the time. We always told each other after the event, which I think helped both of us to trust each other.

The time this started to change was one Christmas around 1980. Our neighbours across the road were hosting a New Year's Eve party, to which many of the couples locally were invited. The hosts were Roger and Julie, a couple slightly older than us, but with children of a similar age, who had things in common with us, such as Saturday morning football with the kids, so we got on well with them. As the party was just over the road from our house, Di and I had agreed we would do our own babysitting, with one of us popping over to check on the children regularly.

Sometime after 11 pm, it was my turn to check on our children, so I was wandering out through the kitchen at the back of the house to exit via the backdoor when I met the hostess, Julie, who I thought seemed slightly tipsy. She slurred “I haven’t had a Christmas kiss from you yet” and she threw her arms round my neck to give me a passionate kiss. I must confess I had fancied Julie ever since we moved in over the road – blond hair, small framed, with motherly curves and boobs to match - so I was very happy to kiss her back. I was worried Julie wanted it to go on forever, when I was supposed to be over the road checking on our children, so I was forced to break the kiss and make my excuses.

Julie said she could do with some fresh air and volunteered to come over the road with me. As we walked across the road, I realised Julie was not as drunk as she had made out. We went through our front door, and I left her in the hall to check on the kids upstairs, they were both sound asleep. As I reached the bottom of the stairs, Julie threw her arms round my neck and said “how about the rest of that Christmas kiss”. Having been warmed up over at her house, it quickly became more than passionate, with her grabbing my bum so she could grind herself against me, and me mauling her boobs through her clothes.

I realised that someone passing the house would be able to see us through the glass in the front door, so I suggested we go through to the kitchen, closing the door behind us, where we continued our passionate embrace. I decided to chance my arm and began hitching up Julie's skirt – what's the worst that could happen, a slapped face and maybe she wouldn't talk to me for a while – and I was delighted to find suspenders and stockings. As I mauled her arse, she murmured 'you naughty boy', which I assumed meant approval, so I slipped a finger inside her panties, where I found a very wet pussy.

I had lifted Julie up onto the edge of the kitchen table, so I could pull her panties to one side and slid 2 fingers into her sopping pussy, causing her to orgasm noisily. All of a sudden, Julie grabbed hold of my shoulders and said “I'm not on the pill, Roger has had the snip so you will need a condom”. Needless to say, I didn't have any and there was no chance of getting any at that time of night, so I should have felt instantly deflated. Never to be defeated, I said “OK, we’ll have to use oral only” and I knelt down in front of her, pulled her panties to the point where I heard something tear and thrust my tongue into her sopping pussy.

Julie was obviously well up for a lot more than a Christmas kiss, as she orgasmed noisily, her vaginal juices running all over my face, she tasted just as good as she looked. I could have kept her orgasming for ages, but I was conscious that we might be missed over the road, so I started to allow her to calm down after the 3rd orgasm. As I stood up, she wanted to lick her juices from my face, then she said “my turn now” and she pushed me back against the wall to start rubbing my erection through my trousers. In no time at all, she had my trousers and pants round my knees and began slurping my very stiff cock. Ever the gentleman, I thought I should warn her that I was about to cum, but she simply fastened herself onto my cock and swallowed the lot.

Afterwards, she said something about cleaning up, so I found a clean tea towel in the drawer to wipe her dry, my cock was already clean as she had licked me all over, and we popped the tea towel in the washing machine. I had, indeed, torn Julie’s panties, but she said she would go upstairs when we got back to her place to find a clean pair. When we got back to Julie’s house, I waited outside the back door for a few moments while she went inside, hoping nobody would notice we had returned together.

I got myself another drink from the kitchen and went back into the lounge to circulate. When Julie returned from upstairs we smiled at each other, I hoped that nobody had noticed us. After a few minutes, my wife Di, came up to me to ask whether the children were OK and I said “yes, fine”. Di said I had been gone a long time, so I said that one of the children had been a bit restless, and I had stayed at our house for a short while to allow him to settle. Di said “oh, OK” and nothing more was said.

The party went on until nearly 2 o’clock, when Di and I went back to our place to bed. A couple of days later, after we had put the children to bed, Di said what a good party it had been, and I agreed. She reminded me that it had been her turn to check on our children at 12.30 am. She said that, as she left our house, she had met Keith from a few doors along from us who was on the way over to check on their children. I said “yes, a lot of the couples close by seemed to have done that”. She said they had got chatting and she had wandered over to Keith's house and they had ended up fucking each other.

This was the first time Di had gone all the way with another guy and, in hindsight, I wondered whether I should have felt jealousy, or some other strong emotion, but I didn’t. Di went on to tell me some of the ‘gory details’ and I just felt happiness that she had clearly enjoyed it. Keith had automatically assumed he would use a condom, which Di had found a bit of a barrier, but it hadn’t spoiled her enjoyment with her first ‘new partner’. She had been on the pill since our children were born, so it wouldn’t have mattered if they hadn’t used a condom.

Needless to say, I admitted to Di my own dalliance with Julie at the party, and Di said she had guessed when Julie came back into the house and went upstairs. She had made eye contact with Julie briefly and the look on her face said it all. She said it had been partly that which had resolved her to ‘go for it’ when she met Keith outside.

To this day, I don't know whether Julie had told Roger about what had happened in our kitchen, and I wasn't about to let the cat out of the bag by asking. Suffice to say that we remained close friends until we moved away with my job move a couple of years later. Work and bringing up our family remained our focus for more than a decade, but I hope to write more about our adventures in due course.
