I walked around the house, I couldn't think about anything else. All that ran through my mind was one thing. No matter what I tried to concentrate on, nothing could push the wicked thought that kept intruding on me in my reverie. I walked around like a man possessed. And that was the problem. For that was what I wanted. More than anything. I wanted to be possessed. And by nothing other than my neighbour's dog. And the best part was that the moment was drawing closer every second.

A beautiful black retriever. He stood almost three and a half feet to four feet tall. I had seen him parading around the yard. The master of his domain. And all I could think about every time I watched that dog strut around his yard was one thing and one thing only. I wanted that dog to fuck me. Nothing more. No morals. No special feelings of affection or playfulness. Nothing so sublime or nice. I just wanted to be fucked and fucked hard by that black beast.

I would lay in my bed at night and imagine those legs wrapping around my waist. I could literally feel his weight as he lay on my back. Feel his hind legs scraping against the back of my legs as he humped forward to bring his cock closes to my asshole. And, finally, the moment of bliss as I would feel his cock probing at my ass. And I wouldn't have to guide him at all. Something in me knew that the moment that dog got me in the right position, he would just jump on me and rip my ass apart.

In fact, as I paced back and forth, I decided to face the facts once and for all. I didn't want that dog to fuck me. I wanted that dog to rape me. I wanted that dog to fuck me so hard that I would be crying from the pleasure and the pain. I wanted to find myself trying to move off, only to feel him pull me back with his forelegs, hump up to me to seat his cock better in me, and fuck my brains out. To fuck me whether I wanted it or not. To make me a bitch in the best way possible. And to fuck me for as long as he wanted to. And all I would be able to do would be to couch there as he fucked my ass and wait for my master to finish with me. I would service my master's cock like a good bitch and be happy that he was fucking me.

I had been planning this for over two weeks now. It had started the night I was in my living room getting fucked by my dog. I happened to look out my living room window at one point and was startled to see the neighbour's retriever standing in the yard staring straight at me. I was so stunned by the look of intense concentration that dog was giving me I could only crouch there, as my dog fucked me, and stare back in mute shock. I know it sounds weird, but I'm almost certain that dog knew exactly what was happening. I was so wrapped up in staring back at him I never felt when the knot entered my ass. It was only when it started to swell up inside me that I realised that I hadn't wanted to tie that night. But it was too late. And suddenly, it didn't matter. In fact, I wanted to tie. I realised how crazy my thoughts were, but all I could think of was that I wanted that dog to see me tied to my dog.

When my dog was finished fucking me, he stopped for a few seconds, then lay down on my back. I had trained him to lay on my back and not turn on me, because it normally hurt too much during the process, but this time, I couldn't wait. The moment he stopped, I started trying to get him to turn. At first, he didn't want to, but instinct soon took over. For a while, I was sure his knot was going to rip out of me and damage me, but I didn't care. It was almost as if there was one person performing the maneuver, and another standing back watching it. I finally got him to turn and there we were. Me on all fours, my dog, ass to as with me, his cock locked solidly in my ass, the knot tugging on me from inside my ass. And all I could see was the retriever staring at me. During all this time, he hadn't moved. He just stood there, that concentrated look on his face.

Now I was in heaven. I started stroking my cock, never taking my eyes off of him. My dog decided to move about a bit to get more comfortable and his cock immediately started pulling on me from inside my ass. I had no choice but to stop masturbating and backpedal with him. Luckily, he didn't move very far and I was able to keep the retriever in sight. When he stopped, I immediately started masturbating once more. It was one of the most erotic moments I'd had in my life. My dog ass to ass with me, his cock in my ass pulsing as he pumped his sperm into me, the retriever standing in the next yard, staring at me, never moving, all while I crouched there stroking my cock,. I finally came so hard I had to clench my teeth to stop from screaming out. I lost all control of my muscles and started jerking in place. My body rocking as the electric shocks of my orgasm ripped through me. My cum spraying all over me, and the floor, as my cock twitched again and again as I came. And all the while, I could still feel the heat of my dog sperm spraying inside me as his cock pulsed in me to lay his seed in me.

Finally, I started to come down from the orgasm and looked up to find the retriever. What I saw made my heart jump in my chest. While I was being wracked by my orgasm, he had moved over to the fence and was now standing on his hind legs with his front paws on the fence itself. This had allowed him an uninterrupted view of my orgasm. That was the moment I knew. I had to have that dog. I had to get his cock into me. I didn't care what I had to do. I just knew that I wanted that dog to fuck me. I wanted to be his bitch more than anything in this world.

It took my dog about fifteen minutes before his cock got small enough to slip out of my ass. When he did, I got up, his sperm running down my ass and walked over to the window. As I got closer to the window, I could see him start to twitch in that way that dogs have where they seem to move and stay still at the same time. When I got there, all I could do was stand there and stare at him. Finally, I did something I have never done in all my life of zoo sex. Staring him straight in the face, I reached down, scooped up some of the cum running down my leg, and, never taking my eyes off of him, began to smear it all over me. I can't begin to describe the feeling running through me at that point. I knew I was putting on a display for him and it felt right. I reached down again, caught some more in the palm of my hand, and started rubbing it on my chest. Slowly running my hands up and down my body. Until I reached my cock. I could se his tail start to wag and I knew he understood that I was doing this for him.

I don't know how long I stood there doing that, but the next thing I knew, I felt my dogs, nose probing at my ass. Then I felt his tongue start to lick up and down my legs and he started licking me clean. When he got to my asshole, I leaned forward until I was pressed against the window, spread my legs to allow him better access to my asshole, and stood there staring at my future master as my dogs tongue flick back and forth over my ass. And, deep inside of me, it felt right. I was putting on this show for my master. I was letting him see what he was going to possess. I was giving him a preview of the bitch he was going to fuck. I was letting him know that I was his and he would be able to do anything with me he wanted to.

What scared and excited me at the same time was that, no matter how many times I had been fucked, I had always had some modicum of control. I had always felt that I was the one that allowed my dog to fuck me. I gave his access to my ass. I loved to have them fuck me, but it was always on my terms. I could always say no.

Not this time. This time, there was no game here. This dog was going to be my master. And I wanted him to be. I wanted him to take me like nothing ever had before. I wanted to prostrate myself before, offer my ass, and have him fuck me blind. To put his cock so far into me I would feel it all the way inside my stomach. And to finally cum and spray his seed deep into me and make me his. To feel his cock pulsing in me. To feel his knot swell inside my ass and tie me to him until he was finished spraying his cum deep inside me. Like the good bitch I was going to be. His bitch.

When my dog was finished, my head started clearing and I realised that I had been standing at my window, stark naked as my dog liked me clean. Anyone who had been looking hard enough would have caught sight of me. But I didn't care. I took one last look at the retriever, and, smiling at the thought of what was to come, went off to the bathroom. That night, I made my plans to become a bitch.

For the rest of the week, I would wait until the entire neighbourhood was asleep, then, silently making my way out to the back yard, I would strip by the fence and let my dog fuck me. As I crouched there, I would hear the retriever come up to the fence. Sometimes he would just stand there on the other side of the fence while I was getting fucked. Other times, I could hear him prancing about, sometimes scraping against the fence as if he was trying to get through. And I knew he was. I knew he understood what was happening on the other side of the fence. Another dog was fucking his bitch and he wanted access to her. I wasn't a man to him. I was a bitch and he wanted badly to fuck me. I could practically feel his craving through the wooden fence. One night, I heard him whining and I knew right then, at that moment, that I was his. I knew the moment this dog got me alone, he would go to town on me. He would fuck me like crazy and that was exactly what I wanted.

The next day, I struck up a conversation with my neighbour and found, almost bursting with joy and anticipation, heard the words I had hoped against all hope to hear. He was going out next weekend to fish with his buddies overnight. He would be back the next day and would appreciate if I'd keep an eye on the place for him The best part of this was as we stood at the fence talking, the retriever came up and sat there watching me. He never moved. He didn't bark. He didn't wag his tail. He just sat there watching me. And he caught me. The look I gave him was to let him know that I knew my place and was willing to accept it. Wanted it. Needed it. At one point I cast my eyes down from his for a moment, then lifted them back up to stare at him. Only to see him open his mouth and start to pant as he watched me. Then, with a feeling that can only be described as utter joy, I saw his tail start to wag. And I knew he had understood. He knew what was coming and was letting me know that he was ready.

In the following week, I let my dog fuck me by the fence five more times to let my master get a hint of what he was going to get. On one particular night, I don't know what got into my dog, but he was fucking me so hard I was grunting every time he slammed his cock into me and I had to brace myself to stop from being pushed forward from the force of the fucking. Normally, when he gets his knot in me, he slows down. But not this time. I could not only feel his cock in me, I could feel the knot sliding inside of me. And tugging on me every time he pulled back to slam into me again. During that time, I heard the retriever jumping up and down against the fence and I knew he was going crazy over there. I didn't know if he wanted to come and protect me, or just take over and fuck me some more. I came so hard that night that I almost passed out. I ended up slightly hanging from my dog's cock, the knot in my ass keeping me suspended in the air.

But, finally, the day arrived. It was Saturday morning. Then lunchtime. Then afternoon. And finally, after a day of constantly walking around the house, pulling on my crotch and running my hands all over myself; of standing in the bathroom as the water ran over me and holding onto my ass and kneading it in my hands, the moment arrived. At one point in the bathroom, I slipped one finger into me. It was all I could do not to scream as the time seemed to slow down as the hour approached. But finally, it was night. I heard a car pull up my neighbour's driveway. I went outside and saw a Suburban packed with people. They honked the horn and, after a few moments, my neighbour finally came out. He saw me standing in my doorway and, as they drove past, waved to me. I waved back and smiled as he left. At last, the time had come. I was going to my master.

And I was going to get the fuck I had been craving all this time. I was finally going to let him take me. To possess me and turn me into his bitch, and his bitch alone. I went back into the house and sat down in front of the television. I stayed that was for about two hours, not really watching, but marking the time by the passage of the shows. Finally, it was late enough. I went to my room and changed into a T-shirt and a pair of shorts. I took one last look at myself in the mirror, then I went outside to meet my master.

Chapter Two

This was it. This was the moment I had been craving all week long. The moment I had been dreaming of, and wanting more than anything ever before. I knew that tonight was going to be different than any of the other times. All those times, I had been a willing partner in the sexual adventures. Not tonight. Tonight, I was going to assume my place. I was going to be a bitch tonight. A receptacle for the seed of my master and nothing else. I would let him do anything he wanted to, and I knew that after he was done with me, I would crave for even more.

As I walked towards the fence, I could feel my cock start to rise up in my shorts in anticipation of the coming fuck. Because that's what was going to happen. I was going to get fucked. And fucked good. And I wanted him to fuck me. I wanted him to slam his cock into me so hard that I could only scream in pain, and joy, and ecstasy from the feel of it ramming into my ass. I wanted him to fuck me till I cried. Till my heart stopped. I had always heard women talk of getting their brains fucked out. Tonight, I knew I would understand exactly what they meant.

As I got closer to the fence, I could make out a vague outline through it, moving back and forth. And I knew exactly what it was. My master was waiting for me to come over so he could climb on my back, put his cock in my ass, and service me properly. By now, my cock was so hard it was beginning to hurt. My shorts were sticking out in front of me, almost like a signpost to the beautiful sex awaiting me. As I got even closer, I started to hear the sounds that transported me. He was whining. My master was whining. As beautiful a sign as I could have asked for. He wanted me. And as much as I wanted him.

I finally got to the fence and, after stopping for a second to try and slow my heart, I went to it and leaned over. And there he was. In all his beautiful, dark, sleekness. His body quivering in excitement as he waited for his bitch to come over so he could start fucking her. And I immediately knew what I had to do. It came to my mind as clearly as if the words were spoken to me.

As I stood there watching him, I slowly reached down and drew my shorts off. First one leg, then the other, all the while never taking my eyes off him. When they were completely off, I threw them away from me. Next, slowly, as if to make him understand that this was for him, I pulled my T-shirt up and off, then threw that away. Then I stood there. My skin shivering in the heat of the sexual excitement and the chill of the night air. And I understood what I had done. I was not going to profane the area of my master with unnecessary items. I was an offering to him. I was to be his and his alone this night. And I would make sure that I was prepared for him to do with me as he pleased the moment I stepped into his domain.

As I put my hands on the fence and started to climb over, he immediately stopped moving. He sat down and just watched me coming over. Almost as if he was inspecting me before he fucked me. To make sure I was prepared. There was no sound, no communication between us. That was unnecessary. I knew why I was here. And so did he. And the sooner I came over, the sooner he could start servicing me. I finally jumped over the top and, my heart beating like a hammer, I landed next to him. Still he sat there watching me, and I knew what he expected. I slowly lowered myself down until I was on all fours, my ass willingly waiting for my master to fuck me. He stayed still for about five seconds, then, with a slow movement, got up and walked over to me. He stood next to me for a second; then he started walking all around me. Sniffing me on my arms. Then my neck. Then my face. He looked me in the eye for a second, then continued his perusal of his offering. He came to my cock, and, pausing for a second, licked at the head of it a few times. The feel of his tongue sliding on my cock almost made my heart seize in my chest. Finally, he walked around to the back of me and I waited. My body was trembling in anticipation at what was coming. Then, I felt his nose brush against my ass and, oh god...oh joy..he started licking my asshole.

I was in heaven. The soft rasp of his tongue scraping against my asshole was transporting me to levels of excitement I had never felt before. Every time his tongue brushed against my asshole, my cock would jerk from the sensation. I was moaning and crying from the feelings coursing through my body. Like minute, electric shocks; causing me to jerk and twist in place. Then he stopped. And I knew this was it.
