I am new to this forum and im posting this situation out here to people i do not know, because at this point, i am not sure i can share this problem with friends and i definitely want outside advice before i confront my wife with this when she gets home from her parents this week. i apologize if the content here is a little "over the top" so to speak, but i honestly dont know what to do at this initial point.
I have been married for 16 years. Me and my wife are 41, 40 respectively. A few years back, I shared with my wife a fantasy i have had for a long time and that was to see her with another man in a threesome or to have her be with another man when I wasnt there. Either way, the fantasy involved her being pleasured by another man. i explained to her that the fantasy was about her and i doing something extremely adventurous together, even though she would be having sex with another man (possibly with me not there). the thought of us doing something so out of line to our real lives is what completely turned me on about it. it was also the thought of HER being or doing something so completely wild in nature sexually. she is a very conservative person.
The fantasy never evolved much more than talk or via text when she was out with her friends, teasing me that men were flirting, trying to take her home, etc. she told me it could only be just that, a fantasy and for us to only share the thought of doing something like that to stimulate our own sex life.
Her mother is sick and she left this morning (wed) to be with her parents for a few days. I worked last night, late 2nd shift and my parents picked up our kids after dinner to stay with them. they would be watching them since i would be working and my wife would be with her parents. i requested to get out early from work, to spend some time with my wife before she left the next morning. to make a long story short, i came into the house to find her in the bedroom with our neighbor. they did not know i was there and i actually stood there and watched him pleasure her until they were done. we are more acquaintances than friends with him but someone who we have openly talked to about sex with while we have sat around with other neighbors at bbq's and other neighbors parties. there were never any signs before last night, except the silly occasional flirting between my wife and him, which i always assured him to do.
once they were finished, i quickly left the house and just drove away and stayed out until it would have been my expected arrival time after work. by then she was already sleeping. it was 2am when i got home and i stirred for a few hours before finally falling asleep. she was gone before i woke up and i have been afraid to call or text her since.
i dont know how to handle this, because this was MY fantasy and i am the one who initiated the talk and the one who always left the door open for her to be with another man, whether i was there or not. im confused because although i felt jealousy and anger, it was the most sexually exhilarating thing i have ever seen. at first i was mad, because she hasnt mentioned a word about it, but after thinking all day, im sure she is embarrassed and afraid to tell me and her parents situation thrown into the mix doesnt help as far as us being able to discuss this.
I dont know what to do. what to say to her at all. i want to be ale to handle this properly and not drive her away. i just dont know if this is a "cheating" situation or just her "acting out MY fantasy". im hoping this is the latter and i dont know the right things to say to make sure we can communicate properly and keep this open marriage. i know this sounds probably absolutely absurd to everyone who may read this...but please keep an open mind and any advice or comments from those who may have an opinion or experience with this, is greatly, greatly appreciated. Thank you.
