I had recently become friends with Erin and she knew about my naughty side. She knew that I slept with guys that are not my husband and started to ask questions and develop an interest in that side of my life. She seemed interested in experiencing this type of life for herself and mentioned that her and her husband were keen on the idea of somebody joining them... Erin could tell that I was up for it. Later that week, she invited me over to meet him and this is what happened. Now they have opened up their relationship, just like me
