3. Life goes on
Since then everything became "open", in that very sense. Something like, she texts or calls: I'll come today with a friend; or: I'll be staying at a friend's place, will be late. It used to be more often, but now it is about once a month.
Indeed, she comes with a "friend". Sometimes the friend has already been here, but usually, it is a new guy. There are long-term lovers as well, but they all live far away. I do not know where she finds "friends"; I never asked, it is none of my business.
The three of us sometimes have dinner, but more often we just drink a glass of wine and they retire to the guest bedroom. And she never (well, hardly ever) spends the whole night with him. She always comes to me afterward, after taking a shower. If she "stays at a friend's place" - the same thing, she is normally back with me at 2-3 am.
When the girls grew up, my wife got a job in a transportation company. And somehow she advanced very quickly: six months later she was already leading a team of six people, all of whom were much older than her. Well, she is smart, reasonable, thinks quickly, counts money well, has leadership skills, but it is still surprising. More precisely, it would be surprising if I did not know her. She instantly figured it out who were the people in charge, and behaved accordingly. As you imagine, there were "working" past midnight, "business trips", etc. But she got what she wanted: now she is her own boss, and things are going well. Covid, of course, has hit them hard, but the company continues to operate, and not at a loss.
I did not care about her fucking her senior colleagues to help advancing her career. But I was not happy that she, an almost non-drinker when we met, started to abuse. More and more often, she returned from midnight "meetings" tipsy. I did not say anything, but she herself figured it out and stopped. Now the maximum is a couple of glasses of wine a day, and not every day.
It somehow did not work out for us with group sex and swinging. Not our thing at all. My own first experience was on a professional trip in one of the developing countries. A colleague there suggested an MMF with one of his many local girlfriends, and I was a complete fiasco: I just could not get erected. Although the lady was quite cool, young and cheerful. She joined us during her lunch break. She was married, said that her husband did not know anything, and if he found out, he would kill her. There were other occasions, sometimes even successful, but, in general, it is not my thing.
We also tried it together, even went to a swingers club several times, and it did not work either. She herself prefers privacy. A couple of times I tried to ask what she and her "friend" were doing there (well, it's clear "what," but details!), and each time she escaped from answering. Peeking was out of question.
Naturally, I also started dating other girls. True, much less often than Petra: my libido is not nearly as powerful. Also, it's easier for a pretty perky girl to find someone than for a shy guy of ordinary appearance. But it happened anyway, my wife knew and had nothing against it. I rarely bring my girlfriends home in the evening, but I have irregular working hours, so I can do it at any time. I also profit from frequent professional trips. In short, I do not deprive myself from pleasures. It happens with colleagues, and with acquaintances, and with strangers. I also go to prostitutes, though Petra does not really like it, not out of jealousy, just because it eats money; but she never reproaches me in explicit terms.
