This is my first time posting on here, but I've been lurking for a while, so thanks for all the tips and info. A little about me and my wife: We're from England and both in our mid 40s (been together since we were teens), we started with this about a year ago, S went to Spain on a girls/work holiday, I knew they were a pretty naughty crowd and the location is infamous, and I'm not at all the jealous type, so I told her if she wanted to have a holiday fling I was fine with that as long as she tells me what's going on. Sure enough, S met a guy (from UK) there and the next night they were having very passionate sex in her room, literally he fucked her 5 or 6 times that night. Same thing the next evening. Since coming back she's met him a couple of times and it's been similar, hours of fucking (I'm amazed she doesn't get blisters tbh). I'm ok with it, I'm probably not a true cuck as I'm not into humiliation but I know her sex drive is greater than mine, and in fact this has resulted in our sex life improving, and as I said, I'm not the jealous type, so as long as I don't feel our relationship is threatened I'h quite happy with it. The guy was married, which suited us as apparently he had no desire of leaving his wife, but I think that may have caused problems as they couldn't arrange to meet often. So, eventually S goes onto AFF and sure enough gets lots of attention. She's now hooked up with 2 other guys, both mid 40s with wives and kids, who apparently are not getting much of a sex life at home. Now with both of these guys the sex has apparently been amazing, literally fucking all night and coming in her maybe 6 times. In all these cases they don't know that I know, or that she has other lovers apart from them. So as far as they're concerned she's their mistress, and she's very keen to dress and act accordingly. They book great hotels and take her out for nice romantic meals before all the fun begins. So what I'm wondering is, is this typical for wives out there having extra marital sex like this, is it normal for the sex to go on all night? It's just that I'm the same age as them and I don't think I'd have the stamina. I guess it's just the novelty factor of a new and taboo relationship, plus of course S is a hottie.
