There is a video on Youtube saying that a girl shared her boyfriend with her best friend, which arouses significant argument over whether should invite friend to a threesome. Many people have different standpoint over this issue. Today, I would like to elaborate my view based on my own experience.
I can never agree with this situation. I think we should never invite friend to our bed for the sake of our friendship and my marriage.
My husband and I are swingers and we have had many threesomes with different people. Also, we had experience with having threesome with our friend, just once and since then we would never do it with our friend or even someone we knew a little.
I still remember the time when my husband and I had threesome with my girlfriend. She was my college roommate and we were getting along so well back then. After graduated, we were separated. I was in New York and she was in LA. We hardly met and talked until she went back one year ago. Since she came back, we hung out again. Although we are not as close as before, but I thought we can pick it up soon. She was pretty and had a really nice body. At that time, my husband and I were having good time exploring new kinks in bed, so I though that if she would join us and have a threesome, maybe it would be a good bond. I invited her. She agreed happily.
Soon we planned a dinner at our house. After the dinner, we went straight from our sofa to bed. It was nice. We had it for two times. We three all had a very good time. Therefore, she said that she would love to do it again sometime. My husband and I agreed. In a year, I can't remember how many times did us do it. We got used to each other and she was just like a part of our sex life. Even she and my husband kissed in front of me, I never thought it bothered me. I trust her and my husband. Until one day, my husband was in the shower. His phone rang. It was her. I picked it up. She said that she wanted to plan another threesome at her house another day. I agreed. After hung up, I found that there were more calls between them. Many of them even lasted for over an hour. I began to feel a little strange. I asked my husband after he finished his shower. I can saw some panic on his face. He explained that they were just discussing on surprising me on my coming birthday. I knew he was lie. I just knew it. But I was too afraid to ask deeper. I was scared of what I would find. So I acted like that I bought his story.
After that, I never want to have threesome with her again and we hardly spoke anymore. I knew I lost her and I lost my husband.
