Threesome can be a Dream or Nightmare

My husband and I have married for over ten years and we are both swingers craving for threesomes since we opened up the new field. I still remember the first time we had a threesome. It was he who brought it up. I was not shocked by it, because at somewhere in my heart, I knew we both want it. I agreed. We invited a friend of ours to join us. Many people maybe would prefer to find someone they have never know. But for us, this is our first threesome, we would like to play it safer. Who knows maybe a stranger could have some kind of venereal disease. Anyway, we three had a very good time. It was a nice beginning.
I thought we would go through jealousy and other stuff, but surprisingly, we didn't. Threesome brought us closer. We feel like that there was nothing that can tear us apart.
Until one time...
Maybe several months after our first threesome, we invited another stranger into our bed. It was a "she". She was so stunning that I even felt threatened by her beauty, but I never cared so much, for that I was confident of our relationship. She was prettier than me, so what? My husband and I have been married for over ten years. I thought sentiment over-wins appearance. But it turned out that I was so wrong. We picked the wrong object. The woman was a stripper and a gold-digger. Actually, my husband and I had some money and we have been living a nice life. The threesome was taken place in our house. I guess she figured out that we were rich. Just like regular, we finished it smoothly and comfortably. She left and told us her phone number and asked ours as well. After that, she has been constantly being our guest and we always ended up having a threesome.
After sometimes, I didn't realize there was something going on between her and my husband. I took it for granted that she and my husband got along very well. Every time they kissed, I never thought of it as a menace. Until one day, my husband was in shower and a message came in. It was a nudity pic of the woman, saying that she would wait him at the same place after launch. That was when I realized there was something more going on between them. But since I don't know where they are going to meet, so I have no way to find out but to ask my husband. My husband was very honest with me. He said that she was just into his money and he has been sending her presents. That was the reason why they kept contacting. Once he quit sending her money and presents, she would never contact him again. So I believed, which was proved to be true.
After that, we never had any threesome.
