Note: This story was dynamically reformatted for online reading convenience. My wife was very horny, we had been drinking a few and she was getting high and when that happened she gets horny. She had called our friend Ken up to get him come and fuck her, but he had company so he couldn't get away. Boy she was pissed at him for not coming up and fucking her. Generally he came up a couple times a week to fuck her and have her suck his cock, as his wife didn't or wouldn't take care of him any more. He had been coming up and fucking my wife for several years now, we generally had a good time when he came both of us fucking her and then she would suck him off while I fucked her. "Why don't we go down to Bobbys." She said "and he can fuck me." Well Bobby hadn't fucked her before, but we had talked about him fucking her, a couple times. I really didn't feel like driving down to his place as I had had probably too many beers too. That's why I guess I asked her if maybe "Max" our german shepherd could take care of her horny cunt. She asked me what I meant and I told her that he'd probably like to lick her cunt for her and that I would play with her while he was doing it. She asked me if I knew anyone who had let their dogs lick their cunt before. I knew that the idea was making her hot, as it was really a nasty thing to talk about let alone do, but when she was hot and horny she'd do lots of things, like fucking my friend Ken. I told her that I had known several gals who had let their dogs service them. She agreed to let him have a few licks but said that if she didn't like it that I'd have to stop. I agreed that it was up to her. I had her put on a nightie and go into our bedroom, where we had the lights turned down and I went out and got Max. He was a young dog that we had raised from a puppy, as his mother was our dog too. He was a good sized shepherd of about 90 pounds. He was a little scared to come into the house as he was a outside dog, but when I took him into the bedroom he was happy to see my wife as he was kind of her dog. He ran over to her and she started petting him. She looked at me and wanted to know what she should do. I told her to open her legs so that he could get a smell of her pussy. As she spread her legs open, she kept petting Max and pushing his head down toward her cunt. He smelled pussy. moving his head down into her crotch he licked her slit, then moving closer to it, he started really getting with the licking. He had his tongue licking her clit and going deep into her cunt. I could not believe how excited my wife become when Max started licking her clit and pushing his tongue into her cunt. She was moaning and rubbing Max on the head telling him what a good boy he was. I told her that I thought Max wanted to fuck her and I asked her if she wanted him to fuck her, she told me yes she wanted him to fuck her. I reached down and felt Max's cock and started jacking on it. It started to get bigger and slid out of its pouch, I lifted him up so his body was up on top of my wife and push his cock toward my wife's pussy. His cock was against my wife's pussy now and I continued to jack him, as the tip of his cock slid into her cunt, as soon as he felt her cunt with his cock, he hitched himself up further onto her and started fucking her cunt. In and out went his cock, she was screaming with joy as she was getting the fuck of her life. Then Max shot his knot into her cunt. She was kissing him and rubbing him all over and telling him what a good boy he was, not realizing that he was tied to her now that his knot was in her cunt all swelled up and that until he went down they would be hooked together. She had came so hard while this was going on, she never realized they were hooked together. I kissed her and played with her tits and nipples as they were hard and she loved her tits played with. She reached and found my cock and told me what a good fuck she had and that she was going to give me a good blow job so I could enjoy the moment with her. Max had got turned around, so his ass was between her legs and it wasn't that uncomfortable for her. as she sucked my cock she rubbed Max's back with her feet. She didn't seem to notice or mind that his knot was still in her cunt. About the time I came, Max's cock slid out of her cunt and boy did the cum run out of her cunt. What a load that dog had. He immediately began to lick and clean her cunt for her. Much to her enjoyment. I asked her how she had liked him fucking her and she said it was great and maybe if I liked he could fuck her again some time. I said that it would be ok. She told me the next time that asshole Ken didn't want to come up and take care of her, she'd let Max do it.
