I was horny but my wife wasn't. I was pissed when I put a hand on her tit and she slapped it away. It was Friday night and I said I was going for a beer and not to wait up for me. I drove over to Art's house. His wife was home but I really didn't give a fuck. I told him I was restless and decided to help him on his Mustang restoration. His wife Diana was already ready for bed so I told her I needed her husband for a while so she shouldn't wait up. She said she was tired anyway. Art popped a couple of beers and we headed into the garage. We worked on the car for a bit and Diana came out to say good night. It seemed all innocent and proper. Art went in and got a couple more beers and we drank. "So what's up?" he asked. "The bitch shut me down and I need my cock sucked" I said. We waited another half hour and when Art went in for more beers he checked in on her. She was asleep. He came back in just a bathrobe with his pants and shirt in his hands. This is a scenario we've played out several times so neither of our wives were any the wiser.

He leaned back against the trunk of the car and opened his robe. I was always amazed at his cock. It was gorgeous with a nice hood. I knew that I would get him to at least eight inches so I knelt in front of him and took his cock in my mouth. I relished the texture of his hood sliding back and forth and within minutes I had him hard. I stood up and dropped my pants. I bent over the trunk and he put a little grease on his cock and on my asshole. He even put a bit inside my ass then plunged his cock in me. I knew that when I was with him I was his bitch. That big cock opened me up and it felt heavenly when he started to fuck me. Art was a fucking stud, and if I were his wife I would let him fuck me every night. He was making my cock hard with each thrust of his big cock in my ass. I actually came before he did. My balls emptied and he was still fucking me. When I mentioned he seemed to fuck me for a long time tonight he said that Diana had sucked him and emptied his nuts earlier so he could go all fucking night. He fucked me for close to 40 minutes. I was actually getting hard a second time when he said he was going to cum. I told him to fill me. He did. He finally pulled out of my extended asshole and said he had to get to bed.

I got home and walked into the bedroom. Linn was still awake. She started to grill me on what cunt I was with. I told her the truth that I wasn't with another woman. She wanted me to prove it. I told her that I don't know how to prove it. She said to strip. I figured she would inspect my cock so I stripped. She knelt down and took my cock in her mouth. When I asked what she was doing she said that she was checking if I had cum earlier. Then to my surprise she reached around and put a finger in my asshole. When she pulled it out it had Art's cum on it. Instead of being pissed she just laughed. "I knew it. You're a fucking sissy." Then she did something I never expected. She said from now on I was her bitch. She told me to lay on the bed on my belly. By the time I got naked and laid on the bed she crawled on top of me and shoved her strap-on in my ass. It wasn't as big as Art's cock but still felt great. She said she didn't care who fucked me as long as I gave her my ass whenever she wanted.

This was a whole new side of her. We talked about it and she said that she thought man-to-man sex was hot and said she always wanted to have an open relationship. She got on-line right there and joined a swingers club. She said we had a date the next night. We went and I got fucked by three guys that night and we have been meeting others ever since. It's been about seven years now and she has seen me suck and fuck so many men I can't even count. She rarely gets fucked by other men but she has had more cunt than I've had cock. We love each other to the end of the earth and this lifestyle has actually kept our marriage fresh. We're pretty much both cock suckers and cunt lickers. I can't wait until next weekend. She said she lined up six big guys to fuck me.
