Good Friends

My wife and I have been together since high school. Unfortunately my wife can’t seem to get pregnant so we have no children. We have been friends with a couple our age with 3 children which we help and enjoy the children. Her husband is a workout freak and built like every woman’s dream. His wife is a little dumpy after having 3 children but is definitely attractive. One night we were at there house hanging out and getting late the kids went to bed we all got fairly drunk. They even turned on a porn video and we were embarrassed but having a big laugh. His wife got up came and sit on me and started a mild lap dance. She told my wife yours is over there pointing at her husband. My wife got up and sat beside him, then he got up and carried her into the bedroom. His wife and I went to the spare bedroom. I told her I had no condom, no worries she said, my tubes are tide. She really was aggressive and wasn’t long I had climaxed inside her. We got up to go see our spouses. My wife was on top of him jumping while he was sucking her breast. He asked had we already finished I knodded yes. My wife while humping said he is trying not to cum. His wife got on the bed with them and had her face either licking his balls or my wife. With his wife’s butt up I entered her and started pumping. My wife watched us and had a major climax which also milked him dry. His wife got on top of me and milked me dry again. We got up and got dressed visited a while then we returned home. While driving home my wife and I laughed about the whole event. This was unexpected by both of us.
His wife contacted me and told me to meet at her house on lunch break. I went and we had hard sex and both went back to work. We do this once or twice a week. She likes sex with me and has bigger orgasms with me. My wife and him don’t get together but about once a month. They don’t know we have sex as often as we do, sometimes I tell my wife. My wife says he is bigger than me but probably would have a hard time orgasming if it wasn’t for his fine body. His wife can’t get enough so sex with me gives him a break. We have had sex with our own spouses in the same bed a few times, something about this is erotic. He is proud of himself and overrates himself. I get good sex from two wives.
