Our first performance with a voyeur

This is the story of our first performance, which happened by chance a few years ago one summer evening. My hubby and I had been at a restaurant for dinner and had perhaps drunk too much of our favorite red wine. We were feeling very uninhibited and decided to take a walk in the park. My hubby, always horny, saw a hidden bench and asked me to sit down to get some intimacy, we started kissing. It didn't take him long to get a hard-on, so he opened his pants and wanted me to take it in my hand. There was no one around, it was dark, so i did it. It was a weird feeling standing there in public with that throbbing cock in my hand while we kissed. I started to jerk him gently and I felt him vibrate, knowing how much he loves my blowjobs and taken by the excitement of the moment I lowered my head and welcomed his boner in my mouth making it slide up and down, again and again .. When I looked up I saw a man sitting on a nearby bench with apparent indifference and was enjoying the show. My hubby noticed him and didn't warn me! Damn, i was blowing my hubby in front of a stranger... Well, at that moment I felt a tingle in my clitoris and a sensation of heat filled my pussy. I was getting aroused... I looked my hubby in the face and saw his smile of complicity. He wanted me to continue, the man was quiet sitting in his place, why not? I continued to keep his cock into my mouth, slowly sucking and licking up and down his shaft, making sure that the voyeur could see me well, until my hubby came in my mouth. At that point we got up, me with the dripping pussy, and we left as if nothing had happened. Of course we ran home because I wanted my orgasm so much. It was so strong... Since then we haven't been able to help but perform in public.
