Are you serious? You think he was in her?
LOL of course he was and not long after this so was I. This is something we do as a couple and she has my full support. Its not like she snuck out and get caught. I literally hounded her into this, well not this exactly, but similar. I was wanting to watch her with two men and me just watching vs one man and I watch/ join but this works for both of us at the moment. I do record some footage for my own "enjoyment" and once in awhile even share a little clip here.
If you are even remotely considering this lifestyle you should sit down and consume 20 hours of porn and imagine your wife as the star and decide if you could live with the outcome. You need to be good with seeing some really intense stuff up close and personal or at minimum know it is happening and your imagination gets the best of you.
If she is with you and stays with you it is for a reason. Likely the reasons you guys got married for. If one factor of your life has changed where sex is not a viable option, at least not an option that can satisfy both of your needs, then you need to decide if you can in fact keep it together if she gets a lover or if that is going to consume your and the relationship. It might, or it may be something you can get through. You might need to talk to a relationship counsellor or therapist.
Our situations are different. Yours is more physical and mine is more mental. Either way it is a huge step and I do not recommend taking that step unless you are both fully ready.
