A few weeks after we returned home after attending our first swingers party, I broached the subject with Di, my wife, of the young couple I had played with. We weren't sure whether their preference was simply threesomes with another guy, or whether they would consider another couple. Although we had gone off to 'do our own thing' at the party, I didn't want us developing separate lives in the swinging scene.

So, I phoned Steve one evening for a chat, explaining that we came as a couple so, if they wanted to develop our friendship further, he should bear this in mind. We chatted for quite a while and eventually agreed to meet for a meal a few weeks later, at a restaurant a few miles from our house. Di had not met Steve before, only seen him at the party, so she was quite looking forward to meeting him. Steve and Katie were quite a bit younger than us and Di said she hoped we might hit it off.

We duly met them at the restaurant as arranged and had a very enjoyable meal, during which Katie was playing 'footsie under the table' with me. I think Di realised what was going on, as she raised an eyebrow at me and smiled several times during the course of the meal, although she subsequently told me that Steve was doing the same with her. The conversation flowed freely and they made reference several times to the enjoyable time they both had at the party.

We invited Steve and Katie back to our place for coffee after the meal, although I suspect we all knew what we wanted. When we got to our place, Di and Katie went into the kitchen to make the coffee, leaving Steve and I chatting in the lounge, sitting on separate sofas opposite each other. When the ladies joined us, I thought Katie looked a little flustered, which my wife told me later was because Di had been sounding Katie out to see if she had any bi-inclination. Di said Katie had not totally rejected her advances.

When Di put the tray of cups down on the coffee table between the 2 sofas, Katie sat down beside me, and Di joined Steve on the other sofa. We started making small talk, but Katie was obviously keen to get started as she began stroking my thigh. This quickly developed into me turning to face her so I could kiss her gently on the lips.

Steve and Di had obviously started 'making out' on the sofa opposite us and, after a short while, Di stood up, taking Steve by the hand and suggested they went upstairs. It felt so horny to watch my wife of nearly 25 years leading a man much younger than her out of the room to get fucked.

My attention quickly switched back to the lovely Katie, who was trying to get inside my trousers. When we met at the party several weeks ago, she had been slightly nervous, coy even, but she knew what she wanted this time. Clothes were quickly discarded and, having slid off her thong, I dived in to devour her pussy, and she was soon orgasming noisily.

She obviously thought she needed to ensure I was fully erect, as she manoeuvred me into a seating position, while she knelt on the floor in front of me and began slurping my cock noisily. Having realised that I was 'ready to go', she looked up into my face and said “no condoms this time, I want you to cum inside me”.

I suppose we should have negotiated this aspect before Di took Steve upstairs, but we didn't and I was faced with making a quick decision. Not wanting to lose the passion of the moment, I just went with it and said yes, allowing Katie to climb astride me and lower her very wet, unprotected pussy onto my rampant cock. She did it very slowly with a broad smile on her face, before she started to slowly fuck herself, taking her pleasure with the occasional gasp and whimper.

It was such fun to tweak her delicate nipples as she slid up and down on my cock, which caused her to grab my head from time to time and kiss me passionately.

We changed positions several times, and I managed to avoid cumming for some time, with Katie orgasming more than once, before we ended up doggy kneeling on the sofa, with Katie about to orgasm again when I felt the sap rising. I thought I should warn her – lord knows why, she had already said she wanted it inside her and she was totally lost in her own pleasure. Her response was “oh yesss” so I grasped her hips to ensure maximum penetration and came deep inside her.

We collapsed on to the sofa, my cock still inside her, both expressing our thanks to each other. After a while, Katie said she wanted to join our spouses upstairs, she said she had not seen Steve with another woman before (indeed, this was his first time) and she thought this might be the first of many.

When we tapped on the bedroom door and opened it, Di was hungrily sucking Steve's cock – she said to clean him up after he had cum inside her – and they both looked up to welcome us. We retrieved the duvet from the floor and joined them in the bed – me beside Di and Katie beside Steve, covering ourselves with the duvet to talk about what we had each enjoyed.

Steve said that he had intended to use a condom (and he assumed that Katie would do the same), but Di had persuaded him to go bareback. Di said she thought it had been much more enjoyable for both of them that way. Katie volunteered that she had persuaded me to do the same, so the ladies were both full of sperm. Di asked Steve whether he had enjoyed sloppy seconds before, which he said he hadn't and Katie said maybe this was a good time for another first.

Cutting to the chase, both Steve and I enjoyed sloppy seconds inside our wives, not a first for Di and I but doing it alongside another couple was definitely very horny. When we had finished, both Steve and I were bathed in a mixture of our sperm, so we went off to the en-suite and bathroom to clean up. I returned to the bedroom to the sight of Di and Katie in a 69, greedily cleaning each other's pussy and orgasming noisily. Steve was standing at the foot of the bed watching them open-mouthed

Steve and Katie eventually went home the following morning but we saw them several times during the following 12 months, both at our place and there's. After a year or so, they decided to start a family, so our regular fun with them ended, although we still keep in touch with Christmas cards.
