This happened, to us, in London, in the 1980s. Or didn't happen - could be looked at that way too.
'Us' was myself and my wife, Chloe.
A bit about my wife.
Chloe is strikingly good-looking and in a sexy way. Some attractive women are ethereal or angelic, delicate, mysterious. Some are statuesque. There are many ways to be good-looking. Chloe's way is sexy.
She often dresses to it too. Hemlines that could be considered a bit too short, tight little shirts that don't button high enough to cover her firm little breasts.
When split skirts were in, Chloe's were sometimes split to the hip. She had this dazzling silk dress in a deep emerald colour, narrow all the way down to her knees, but with a split all the way up one side so that when she sat on a bar stool you could see her panties. If she was wearing any. And it had a narrow split at the front of the chest too, down to her navel, a peek-a-boo.
To sum up, Chloe dresses a little ostentatiously. Even when she's dressed for a funeral, she turns every head when she walks into a room. I know that's a bit of a clichΓ©, but if you've actually seen someone like that you'll know what I mean.
And all this without looking in the least bit common, on the contrary, done with such poise, such sangfroid.
She's also a bit of a flirt. I've seen worse, but not much worse. She gets a lot of attention from men and she makes no bones about the fact that she enjoys it.
We always had an 'open' relationship - we each did things on the side. Not very often, but not rare either. We both enjoyed it immensely. Especially Chloe, she looked as if butter wouldn't melt in her mouth, but sex was actually a kind of core competency for her, she was good at it and it made her glow. She could talk about history or the theatre or food or travel, but all the time she gave off this aura that telegraphed to those around her "It wouldn't take much to talk me into performing fellatio for someone right now." Hard to explain, if you've ever known anyone like this you'll know what I mean.
So another of the things that men found attractive about Chloe was that they sensed they had a shot with her. And they were right, they did. Not every single one of them, but she enjoys sucking men off, always did, and over the years more than a few of them have had the pleasure. (Actually, when she was young she did it professionally, but that's another story.)
The odd thing was though, she wasn't particularly interested in hot, fit, uber-abs, toothpaste-advertisement men, with the tan, the swagger, the biceps, the arrogance. She preferred on the whole, older men, or where they were younger they were more like me - a bit geeky. For her a lot of sex was in the mind rather than in the biceps.
Every now and then we would go to a pub or a hotel bar and she'd pick up a man, usually an older man, as I said she liked older men - I don't mean geriatric, just older than us - and go off with him somewhere and suck him off, or whatever, then come back and tell me about it. We played this game for years, though latterly it was mainly when we were traveling - too cautious about running into someone we knew. I was moderately well-known by that time.
