Last February, my husband and I were at a mountainside cabin of a ski resort with our 3 couples friends and a single friend, Bryce. After a day of skiing and dinner back in the cabin, 1 couple and Bryce came with us into the hot tub. I was sitting between Bryce and my husband. Bryce is my husband’s best friend and my husband has joked about having a threesome with Bryce because he is someone we are very comfortable with and he has a wife sharing fetish he had wanted to explore more of. He loves watching me flirt with other men because it makes him jealous and excited. There was one instance in the past where we ended up sharing a bed and ending up spooning but nothing more, it was before we were engaged and we never spoke about it since. He had initiated it so I had always assumed he found me attractive. I told my husband about it and he was always suspicious that more happened but in reality nothing else occurred.
