I always liked my neighbors feet. When ever she would come to our house she would take her shoes off at the door. If the opportunity arose and no one was around, I'd smell inside her shoes and lick them. They always had a nice salty taste.
Well one time we were partying and one thing led to another and we all ended up in bed and playing. (Me and my wife, and her and her husband). We were playing with each other's partner and I ended up fucking the neighbor. We were in missionary and she had her legs on my shoulders. Her sweet feet were right next to my face. I saw the opportunity and licked her arch then put her toes in my mouth and sucked them. I was in heaven and got even harder while fucking and sucking.
Unfortunately this was the one and only time my wife and I played with them (or any other couple for that matter.) I'm glad I saw the opportunity and took the chance. I filled a fantasy and still jerk off thinking about it. I hope we get another chance someday.
