Let's just start by saying i (39M) never cheated on my wife. I love her and for me, she won the genetic lottery: beautiful face, small frame but huge tits. Totally out of proportion, totally my fetish. The kind of women you don't meet that often and since i'm pretty much conditioned on her at this point i hardly see women on the street that exite me on that level.
After being together for almost 14 years we were seperated for half a year because i started a new job far away. We did a lot of sexting during that time and maybe it was the indirect communication that we really opened up about our kinks, like we had never before.
It started innocently enough: she wrote about a fantasy of us being in some fancy club for swingers, like a resort kind of thing. She wrote about us meeting a couple and me fucking the woman doggy style. I was perplexed and asked her where she was in that scenario and after a minute she wrote "between your legs, licking your balls while you fuck her". That caught me off guard, but i didn't pay it any real thought afterwards. I thought maybe it was just a one time thing.
Fast forward 2 or 3 years to last week, we live together again and are very active, sexually.
In my lunchbreak i go to a restaurant across the street with a colleague. We had a humorous discussion about a guy we were planning to fire because he just didn't perform, is always late and generally requires hand holding with every task, making him more a burden than relief. I remember me joking he will start the new year by starting to look for a new job.
I guess i'm more on the attractive side but like most men I'm super slow in picking up signs when women flirt with me. As in, basically blind and deaf. But there was a girl behind us in line, young brunette, who seemed to REALLY respond to that kind of "bossy talk". Never experienced something like that.
She was basically undressing me with her eyes, hypnotized. She sat a table behind us and when she left and walked beside our table for some reason she had her hair undone from the bun she wore before. She then stood outside right next to the entrance, having a coffee, smoking a cigarette...waiting. Staring at me.
After a while she walked away and i thought that was it but no, when we finally left, she stood opposite the entrance, leaning on her car one foot on the fender, looking into my eyes, smiling. She basically used every signal in the inventory to invite me over to talk but the bumbling husband i am, i simply smiled back like an idiot and walked by her. Seconds later she entered her car and drove away, 20 minutes after leaving the restaurant.
In the evening i told my wife what happened. How that woman had basically switched every light to green to approach her. My wife smiled and thanked me for being honest.
Next day we're about to have sex. We talk dirty. Suddenly she admits she masturbated the evening before to the thought of me fucking that girl right there. "What, in the restaurant?" i ask. "Yeah, on the toilet. Just quick, and rough and dirty, just you stuffing her with your cock, two horny people having fun". I was super turned on and went "yeah, like that" and fucked her rough. It was good.
I'm grateful that she is so open about it to me.
But in the end, i'm confused about all this. Is this just her fantasy? Does she want an actual woman to "share" me, watching me fuck her? I wouldn't even know how to set something like this in motion in rl. Do i have a free pass to actually go for it if find myself in the situation like in the restaurant?
Anyway, this is all new to me, and i'm completely at a loss. Turned on when i think about it, but at a loss.
tldr: My wife fantasizes about me fucking other women on my own and in front of her.
