My girl and I had been fantasizing about a threesome for a while now. When having sex we would sometimes fantasize about how a threesome would be and even had a friend of ours in mind. After maybe two or three months, there was an opportunity where that particular friend would visit us for diner and had planned to stay the night. My girl and I already fantasized about if this could get real and if there was a chance, we would go for it. We had never mentioned this to our friend or even given her any hints.
When the day finally arrived, we had a great diner and very lovely evening. Eventually we all decided to go to bed. Our friend would be staying in the guest room. My girl and I were in bed and again discussed whether we should try this or not. We were both very excited and nervous. We decided to go for it. So my girl got out of bed, went into the guest room and asked our friend if she wanted to chat some more in our room. The three of use than sat on the bed and chatted a little but within a few minutes my girl changed the subject to sex and went even further by telling that we had fantasized about a threesome with her.
