I'm in an open marriage with my wife but lately I very rarely see other women, she occasionally goes out dating dating other men. Together for 14 years, married for 9, we have a 8y/o daughter, DNA test has proved she's mine as the wife was sleeping with another guy at the time but with condoms.
Over the last few years I've been turned on by the idea of her getting knocked up by someone else, and the more I've thought about it the more I've realised I'd be up for it for real rather than just a fantasy. I've touched on the subject with her quite a few times, at first she didn't like the idea but I think she's very slowly coming round to the idea, especially considering she's been wanting another baby for a while now but I've been saying not yet - me secretly hoping she "accidentally" gets pregnant by someone else she's not using condoms with.
So fingers crossed for one day soon she will be up for it!
I've often thought that, because we're both white, if the other man is white then we could get away with saying the baby really is mine and if turns out looking hardly anything like me then we can pretend to say to both our families we've had the DNA test done to prove I'm its bio dad.
Or if she was certain the other man wasn't white then we could say to our families we'd split up for a while and she was sleeping with someone else in that time, then we got back together later.
