My wife and I have been happily married for over ten years now. She is in her early thirties and me, well I'm forty now. Anyway, we have a great sex life and don't have any children. She is small, only 5'2", about 105 lbs, and built very well for her small frame. We will call her Amy for now; the name has been changed to protect the innocent.

We got Internet service about a year and a half ago. As many men do, I was surfing the net one night, looking for all those porn sites, and came across some "animal sex" sites. I had never seen anything like this in my life! I was so turned on by it, the dogs, horses and donkeys fucking women. And these women were sucking, fucking and drinking hot animal cum! It was making me so horny, I was going insane with lust.

Anyway, Amy came by the computer one night as I was looking at a woman giving a horse a blowjob, and gagging on all the horse cum. She said she thought that was sick and I was a pervert for looking at such sick behavior. I tried to get her to get into it, but she was not interested at all. From that point on, I was really careful not to let her catch me surfing the beast sites.

After many a night looking at all those animal scenes, it made so horny I could hardly contain myself. I started fantasizing about Amy and a big dog, I don't know why, but the thoughts of her with a big dog cock in her tight little pussy drove me nuts! I started to wish that I could talk her into it somehow. I didn't ever want to share her with another man, and wouldn't ever consider that, but a big dog, that really made me mad with lust.

I didn't think that it would ever happen, considering how she felt about the pictures she had seen on the net.

It just so happened that one day, a few months later, that new neighbors moved in across the street. We live in a nice middle class neighborhood and we wanted to welcome them to the neighborhood. We went over, after they had time to settle in, and just said hi and let them know we had a good friendly neighborhood here.

To my surprise, a big black lab made his way out of the house and came over and started to wag his tail, and looked very friendly. His name was "Blackjack" and he was about 2 years old and about 100 lb. Our neighbors, Terri and Jack said he was very smart and a friendly dog. We made small talk and then went on our way.

Every now and then we would go over and play cards or just grill out back and we invited them over a few times, just so we could all get to know each other. They were about the same age as we are, so we got along pretty well. Not great close friends by any means, just more or less friends.

Well, about 3 months later, Terri and Jack had to go out of town for a few days and didn't want to board Blackjack, so we volunteered to keep him while they were gone. They left the instructions on feeding, and all that stuff. He was a good dog and I had fun throwing a ball and him chasing it and so on.

They left on their trip, we kept Blackjack in the house, out in the sun room most of the time, where he could look outside and let him out to play during the day.

That night we put him in the sun room and we settled down for a quiet night at home, little did we know it wasn't going to be so quiet after all.

After a few drinks, we got "in the mood" and started the foreplay. Amy pulled off her sweatshirt and pants, and she had nothing else on, I'm sure she had planned this all along. Amy is so hot and sexy, tight little ass, her blond little patch of pubic hair, and perky little tits. She was so horny from the wine. We got hotter and hotter, I had my fingers in her little pussy, and she was dripping all over my fingers. About the time we were really into the foreplay, Blackjack started to howl and carry on. I don't know if he knew what we were doing and wanted in on the action or what, but he wouldn't shut up. He just kept on and on; it was very distracting.

Finally, I said, "I have to go shut up that dog".

I went out to the sun room and he was standing there waging his tail and looking up at me, like what were you guys doing out there? I reached down to pet his head, forgetting that the scent of Amy's pussy was still on my hands. He went wild licking my fingers; I could see that he really liked the taste. I also saw that he was getting aroused, his big cock was sticking out a little from its sheath. Blackjack licked all the pussy juices off my fingers, so I decided to try a little deception on Amy. I left the door open just a little and told Blackjack "to stay".

I went back to the den where Amy was finishing off another glass of wine, by this time she was getting really blasted, and that was fine with me. I knew the more stoned she was, the better chance I had of getting her to do it with Blackjack. I knew Blackjack would come out sooner or later and sure enough, it wasn't long before I got my wish.

Amy was naked sitting in the couch, drinking another glass of wine and we were about to get started when, Blackjack came around the corner of the couch and stuck his big black nose on her leg. She jumped and screamed, scared by the sudden intrusion of the big dog.

She said, "Get that beast out of here, he scared me to death."

I told her he just trying to be friendly and she said she didn't care, she wanted him out. About that time, Blackjack started to lick her hand and she softened up a bit, petting him on his big head.

"Good dog," she said, "You scared me to death, Blackjack. Don't do that again, OK?"

About that time, Blackjack starting licking her leg.

She said, "Now don't do that, stop, you are being a bad boy".

But Blackjack would not stop; he started to edge his nose toward her pussy area. She was trying to push his head back, but he was too strong, he must have really got excited when he got the scent of her pussy. I told her, I think he likes you, look at how excited you have gotten him. Amy looked down to see his huge cock, sticking out from its sheath. It must have been 7 inches long now and it was not all the way hard. Amy's face blushed blood red when she saw the big bright red cock. "Oh, my goodness, she said, that's really a big one".

By this time, the wine had really loosened up her, and the big dog's cock excited her. I told her to reach down and touch it.

She said, "I couldn't do that, he may bite me."

I told her he would probably like it very much. She reached down and started to stroke his big tool, he really liked it because his dick started to grow and grow. Blackjack knew what was going on, at that moment, his shoved his nose right in Amy's dripping little pussy. She jumped at first, and then I told her to just lay back and enjoy it.

Before she could say anything, Blackjack was lapping on her pussy like crazy. Amy was starting to moan and groan, her eyes starting to roll back in her head. Blackjack licked with his big rough tongue and she loved every second of it. She spread her legs wider and wider to let him get his tongue in as far as he could. She was dripping wet, pussy juices flowing wildly and that big black dog was licking her clit and she knew she was going to cum. Blackjack had his tongue up in her pussy and her pussy was on fire, like she had never dreamed of before. She popped her little ass up as far as she could, so he could lick her little asshole out too. He granted her that wish; he started to lick her ass like crazy, his rough tough taking in all of her woman juices.

He started to lick so hard, that he put his tongue up her ass and she cried out, "Oh yes, suck out my ass and my pussy, you big beast!"

She started to cum and she screamed out in pleasure, her multiple orgasms driving her to the brink of passing out. Never had she had such pleasure and from an animal. She didn't care what was she doing now, it was too late to stop. She wanted more of this big dog and she didn't want him to stop licking her pussy and her little ass.

When she finally stopped cumming, she was shaking from the experience. She looked at me, Blackjack was still licking on her ass, and she was a little red faced.

"I can't believe I let him do that to me," she said.

I told her that was OK, and I was glad she had enjoyed the experience. At that time, Blackjack had laid down and started to lick his big cock. It was still hard and sticking out.

Amy looked at him and said, "I want you in me, you big fellow."

I was so horny, my dick was as hard as a rock, but I knew she wanted to be pleasured some more by our big friend.

Amy got him to come over and started to stroke his cock, it started to get harder and harder. Then to my utter surprise, she got down on the floor and put that hot dog cock in her mouth. She started to suck on the big lab until his dick grew and grew. She was panting like a dog herself as she popped the huge dick in and out of her tiny mouth. Blackjack loved it too because he started to hump her mouth.

Then she got up and bent over the couch with her round little ass sticking up and asked me to help our new friend find his way in. Her pussy was still dripping wet, and I helped guide Blackjack into her tight little pussy.

She was amazed how big he was! "Oh, God, he is sooooo big and he is soooo hot!"

Blackjack started to hump like crazy, right from the start. He was humping as fast as he could, poking his big rod in and out of her. He must have been a full 9 or 10 inches now and she loved it. She was starting to scream with every thrust of the huge cock. Each time he thrusts into her, it made a whooshing sound. Amy was humping in rhythm with the mighty K9, meeting every thrust with his. He was starting to whine and drool dog slobber in her hair and on her back, his claws were digging into her flesh, but she didn't care, she just wanted as much of him as she could get into her hot, steaming pussy. She was mad with passion; she couldn't believe she was letting this big animal fuck her. She was ashamed but at the same time wanted him to fuck her, wanted his big dick ramming in and out of her with such force, she thought she would black out.

Blackjack kept right on fucking her, he just continued on and on and on, must have went on for 20 or 30 minutes. Amy was panting and trying to catch her breath with each stroke of his animal tool. She was pouring with sweat, and Blackjack was panting and drooling all over her, but she didn't care.

She just never wanted him out of her; she wanted his mighty dog rod in her forever now. Finally, she said, "He's starting to grow bigger, oh, my God, his dick is soooo big I don't know if I can stand it."

His big dick had grown and grown and now his knot was taking over Amy. I thought that at one time he would split her open; his tool was so big. She started to scream more and more as the knot was really causing her some pain.

After another minute or two, she seemed to be OK and was now enjoying it. Blackjack was now humping like the wild beast he was, pounding Amy's stretched pussy with his knot. He started to whine more and more and I knew that he was close to cumming.

About that time, Amy was whining and moaning too, her eyes still rolled back in her head.

"Oh, ooooooohh, oooooooh," she cried, as she felt the first gush of hot dog cum shoot into her tortured vagina.

Blackjack just kept on cumming and cumming, she thought he would never stop and she didn't want him too. She loved that hot animal cum shooting off in her. She thought that it was soooooo hot!!!! She loved it, she hoped that big dog cock just kept filling her up with his steamy cum. Blackjack kept on cumming until he finally tried to lay down, but he and Amy were tied up and they had to lay down together. Finally after awhile, the knot slowly went down, and Blackjack popped out of her. I could not believe the amount of dog cum that came out of her. It just gushed out of her pussy, and down her legs, thighs, and down into her little ass. She had been filled up with hot animal cum and I just loved it. My dick still ached from all the action and I still hadn't had any relief. Seeing all the steamy dog cum pouring out of my wife's little sore pussy was more than I could stand. I went over and Amy took my swollen cock in her mouth and sucked on me till I came with a load in her mouth.

After a brief rest, she looked at me, her face still red from the good dog fucking she had received and said, "I can't believe that I let an animal fuck me like that."

I told her that was OK, as long as it was an animal and not another man. She said she would never fuck any another man but me, but she sure was going to fuck Blackjack again, as soon as she could. She also added that we needed a good dog of our own. I told her that was OK with me.
