In both threeomes that I have engaged in, the woman had desired to see the men do things to each other also. If you had the good fortune to have a threesome, we you asked by your partner? If I was in a FMF threesome I would certainly enjoy watching my wife try bi.
Our first mfm was over 50 years ago male on male was not accepted or it stayed in the closet, on the other hand there were a few lesbian relationships. So yes a few of the girls played together. Me I just had no desire different times I might have been curious, but the girls I knew wanted both men for themself.
Well, I had one MMF threesome fifty years ago. It was with a friend of mine and his wife. There were both ten years older than I. The wife knew that her husband was active with men. She thought that he and I were having sex together, but we were not. Anyway, she definitely wanted to watch us get it on, and at one point took his cock in her hand and tried to force me to suck it. I had no interest at the time. Eventually, he and I did start a relationship together. Today, if I was in a threesome with another man and woman, and the woman asked me to get it on with the other man, I wouldn't hesitate at all.
I told my wife about my relatively frequent sessions with my SB that happened 20+ years before I met her. At first she was somewhat shocked, but overtime the idea grew on her, to the point that we would occasionally watch MMF, gay, and lesbian porn (her fantasy). COOL! She was blossoming sexually! we got to anal and pegging, which was a lot of fun. Then we took the plunge with MFMs with a good friend of mine, and they were all great. She was the center of attention…. as it should be. During our last time with him, and early in the “preliminaries”, he was on his back on the bed and she was between his legs going down on him. I got my face about 2 feet away from the action to get a close-up of watching her work him over. I kept thinking I wanted to do that, and she could see that I wanted to. So at one point, she removed him from her mouth, and pointed it at me. It took all of my willpower to decline, as our friend was extremely straight, and I did not know how he would react if I went down on him. I did not want to ruin the vibe that was developing. Afterwards, she asked me why I did not suck on him, and I gave her the same explanation I just mentioned. Later when we talked about it, she thought it would be cool/hot to find a suitable guy for a MMF. we looked, but there were just too many unacceptable candidates. So sadly there went that idea. we are older now, and she no longer has her once aggressive sex drive… the dreaded M word. it hasbeen a couple of sexless years….. Driving me crazy. But what are you gonna do?
