Who's Fooling Who

For five months during 2019, I loved how my neighbours John (27) and his wife Kate (24) were around each other.
They made out they were so much in love. And they also made out, they were always having sex.
The thing was, I was fucking them both, without the other knowing.
They both work for the same organisation, but John has night shifts in his weekly work rota.
So when he was on his night shifts, I had my nine inches up his wife's pussy and arsehole all night. Kate is such a horny dirty bitch, I always enjoyed just how much she craved my cock.
You could set your watch by what time John got home in the morning. And invariably I'd leave within fifteen minutes of him arriving home. But not before Kate had had me fuck her again.
Kates work pattern is a day out from her husbands, which means one day a week, he's in the house on his own during the day.
That's when he'd call by my home for gay sex. John's just as much into my dick as his wife, and absolutely adored me destroying his arsehole, after he's been sucking on it first.
In many ways he could take a far rougher fuck than Kate, and John sucked cock like a whore.
Covid struck and our beautiful liaisons kind of stopped. Although I was still fucking Kate every now and then.
However now that I've begun a new job. Its given me far more time at home, and that means my neighbours have both been visiting me again. Only they now visit together.
What I never knew, and they certainly didn't tell me, is they always knew about each others sexploits with me.
They'd swap accounts of me fucking them, without me ever knowing they were doing it. Not only that, but each time I'd fucked Kate in the morning, with her demanding I cum in her pussy or arsehole, she'd have John tongue out her fuck holes immediately when he got in.
John has a five inch cock, but is extremely good with his mouth, as I know only too well. So I'm their cock substitute. And they saw it only fair, that John being bisexual like myself, enjoyed my cock too.
Now when they visit, I get to fuck them both, but John now prefers I fuck his wife more.
He's definitely not Kates cuckold, but he likes to play the part as I fuck his beautiful wife. And Kate these past few months has become extremely sordid with John around. Its almost as if she's trying to show her husband what she could be like with him, if he had a large cock
Having said that, they are very much in love together.
