Group Sex

My wife and I have been married for three years. Deb is a pretty, slender woman with a very nice body. We were invited to a party with two other couples we know. The invitation had a hint of possible sexual activity. My wife had been shared a couple of times with the husband of one of the couples. At the party we all had a great dinner, good conversation, and we got high. Our host suggested going to the living room. After a bit, he started making out with his wife and eventually took her clothes off. My wife and I started playing with each other and watched as the couple starting fucking. That completely broke the ice. Before the evening was over, my wife had been fucked by the two other men and I had fucked the other women. At one point I heard my wife, who was fucking the guy she had been shared with before, that it was good to have him in her again. When I finally fucked Deb, she was full of cum. It felt great. The three couples have gotten together for sex three more times. It's more uninhibited each time. I watched Deb at the last one with two dicks in her.
