I was amazed to see the glistening greyish pink penis emerge from its sheath right before my eyes. My face was down there between the dog's legs as its cock slide smoothly from its sheath. It was much bigger than I had imagined. It was a little like watching the slimy aliens emerge from the shells in the Alien movie with Sigourney Weaver. I tried to back away, but Jurgen held me firmly in place so that the pinkish grey canine cock emerged slowly toward my mouth. I was fascinated by what I was seeing. The dog's cock was as big as any man's, and very long. I noticed it was bent as it reached its full length and a its base featured a large bulb wider than the shaft. It was much different from any man's penis I had ever seen.

"Kiss it," Jurgen said in a low, husky voice. "Kiss your dog lover."

I closed my eyes as Jurgen made me kiss that thing. I couldn't believe it was really happening. I couldn't believe I was really doing that. The dog was very aroused. I could feel it was very tense and anxious.

"Now lick it, bitch. Taste it."

Diesel held still and Jurgen was silent as the tip of my tongue came in contact with the dog's erection. This was so forbidden! I could smell the dog, it coarse hairs brushed my nose. The pungent taste filled my mouth. An erotic stickle warmed my belly.

On Jurgen's instructions, I then knelt down on all fours. Jurgen was excited. He said we would just see what the dog would do. I felt the dog sniff me, sticking its cold nose in my crotch. Then it began licking me with its warm, rough tongue. It felt like sandpaper on my pussy.

The dog circled me, sniffing. I knew I was in trouble from the way its ears were perked up and the hair on its back was up. The dog got more excited and started growling a low throaty growl, sometimes making a whining noise. I made myself hold still. I was doing this for the man I loved. I was showing him the totality of my devotion to him. Jurgen said something in German and the dog responded immediately with a yelp and climbed on my back. Its paws digging at my shoulders, its nails raking my back as the dog tried to get on me. It was struggling to get a hold of me, growling, digging its hind feet into the carpet. I was relieved when it gave up and slid off me. The dog was not finished with me, though, and it circled me, licking my face and growling as it passed my head. When it got behind me again Jurgen repeated his German word and the dog mounted me again.

This time its front legs locked around my waist with amazing strength. Its grip was like steel. Its big chest rested heavily on my back, its muzzle was on my shoulders and I felt its drool on my skin as the huge dog started to frantically hump me. I couldn't believe this was happening, but I braced myself against its weight, waiting for it to be over. Its claws scratched my butt, stinging me.

I was not prepared for what happened next. I hate to think Jurgen intended it to happen. Things just got out of control. I did not think it was possible, but I felt its cock against my thigh. It was hard, wet and long. It was also incredibly warm. I started to wriggle and cry, but the dog growled meanly until I held still. It was getting desperate. I felt its warm tip touching my pussy and I thought I would die.

If I thought the man I loved would intervene to spare me the indignity of being raped by his dog, my hope was shattered when Jurgen reached between us and helped guide the canine cock into me! The big dog was straining and digging into me, jabbing its warm penis into me, driving deep into me, as deep as any man had ever gone. I was stunned and confused by what was happening. I felt paralyzed by my fear. I was surprised at how wonderfully warm the dog's penis was inside me. It was not an unpleasant sensation. Its front legs tightened around my waist and I felt like I was in a vice as the dog humped wildly into me. I was in a fog. I heard the sounds of the dog's tags jangling as it humped me frantically. The buckle on its collar was scraping painfully along my back. Diesel was growling and wolfing as it strained into me. It's back feet treading the floor. I felt the dog pressing deeper into me and realized Jurgen had his hand on the dog, pressing it down. I winced as I felt that last inch, that swollen bulb on the base of its cock, enter me. Jurgen knew exactly what he was doing. The dog's chin and massive chest rested heavily on my back. I could hear it panting, its drool on my skin. That strange penis pulsated inside me. Jurgen never made a move to stop his dog. I had had enough. I got panicky.

"Get him off me!" I begged in a shrieking voice.

Jurgen did nothing.

"You might want to keep the knot out. Otherwise you might get hurt," he said in that husky voice.

I had not thought about the knot. I reached down between my legs and touched the canine prick ramming into me. I felt its hardness and heat and then I felt the knot. It seemed huge! It felt like it was the size of a tennis ball, certainly more than I could handle. In panic, I clenched my muscles tight and pushed against it with my fingers.

I was gasping and crying. It was like it was not really happening. I could not believe it was me this was happening to. Behind me, I could hear my lover's voice encouraging his dog. "Atta Boy! Good Dog. Get her, Diesel!"

The big dog was out of control.

I tried to calm the dog down with a soothing voice, but there was no calming this dog. It was an animal, not a man, not a lover who cared about my feelings. The dog did not care if it hurt me badly. There was no reasoning with the beast. Instinct drove it to drive its knot into me and it certainly wasn't going to be gentle with me. I was clumsy and outmatched. With a searing pain and suddenness that made me scream, the knot was inside me.

Suddenly, the dog froze on me. I felt its muscles tense. That dog's penis pulsed strongly three times inside me. There was an incredible sensation of warmth and fullness inside me. The dog had been frenzied, and fast. It had only been on me a few minutes before its come was oozing down my thighs. I thought it was over, but Jurgen knew better. He warned me not to move. I felt the dog's cock swelling inside me, growing bigger and thicker. Its forelegs still gripped my waist as it rested its massive chest on my back. The dog was panting quietly. I could feel its heart beating against my back. I remembered how it took three men to keep Diesel from damaging the brood bitches it was bred with. Now I was the brood bitch. There was an insistent sense of fullness inside me as the thickened dog cock filled my womb. I had never felt anything like that before.

"You better not move."

After awhile, the panting dog raised one hind leg over my hip. I felt that thick knob at the base of its penis inside my vagina as it shifted its position until the dog and I were locked together back to back. It was that swollen knob that held me to the dog.

"That's the tie, honey. Don't fight it. Stay still if you don't want to end up in the hospital," Jurgen said in a low whisper.

I was terrified, humiliated.

I stayed "tied" to that dog for several long minutes before its cock slipped free. I was a mess. I was trembling. My back was scratched from the dog's clawing and I could feel the dog slobber in the scratches. I looked down and saw blood on my thighs. I worried about infection.

I couldn't stop trembling. I crawled away and knelt next to the sofa, shivering as I tried to compose myself. I felt sick to my stomach. I needed reassurance from my boyfriend, but Jurgen was across the room hugging his Rottweiler.

"Good dog!," Jurgen shouted, rewarding the happy dog with a cookie and patting its head. "Good work!"

I felt ashamed and abused. I was also aching and scared. I wiped away the tears and found my glass of wine. I needed something to get the bitter taste out of my mouth and soothe my stomach. I was sore and bloody.

"You were beautiful, Julie," Jurgen said, as he rubbed his dog's head affectionately. "I always wondered what that would be like. Incredible."

Like Diesel, Jurgen's praise washed away my bad feelings. I desperately needed to be held by Jurgen, to sleep in his arms, to be kissed and reassured that he loved me. Jurgen did not hug me, though. He did not want to confuse his dog.

Jurgen would not let me clean myself. He thought the dog would want to do that. The dog was agitated, pacing the room, growling and barking.

"The dog's jealous. You're his bitch now."

To emphasize that point, Diesel came over and very aggressively licked me clean.

"Sleep with your lover tonight," Jurgen said when I tried to get ready for bed. He made me sleep on a blanket on the floor with the dog. I laid curled up with the dog all night. The dog wanted its space and was not at all affectionate with me the way it craved affection from Jurgen. When I got cold and moved closer to the dog in the middle of the night for its warmth it responded with a warning growl. It was crazy.

In the morning Jurgen scraped oatmeal into the dog's bowl and said, "Here's your breakfast." He said I had fleas and smelled like a dog. He only called me by one name after that - bitch. I was Diesel's bitch, exclusively Diesel's bitch. As if on cue, the dog tried to nose its way into my crotch. I slowly backed away and the dog whined as I closed the door.

I went back to my apartment the next day, locked the doors, took my phone off the hook and kept the lights off. I filled the tub with scalding hot water and made myself sit in it for hours as if I could sterilize my body from that forbidden act. I sat in the tub and cried out of shame and hurt. I felt abused and betrayed. I loved Jurgen so much. I wanted to marry him. He was just looking to find a woman to sic his dog on. I could not really hate Jurgen, though, and after awhile I started to think about the incredible warmth of the dog's cock inside me and I found myself touching myself until I orgasmed in the water. The orgasm was a intense physical relief from the stress that had built up inside me, but it did not relieve me of my guilt. I still felt so evil.

I did not go to see Jurgen after that. I was too humiliated and repulsed by what had happened. I stayed at my apartment, eating whatever I had in the refrigerator because I could not bear to go outside. I slept a lot. I was like those bitches after Diesel had finished with them. I was exhausted and sore. I was relieved, though, that the bleeding had stopped after the first day. I took several baths a day, brushed my teeth and gargled with Listerine every hour and dabbed Miss Dior perfume all over me. I was sore and worried. I missed Jurgen. I had loved him more than any man.

I stopped going to work and I did not even care when my boss called me to tell me I had been fired. I was numb.

After more than a week -- the longest stretch I had gone without my Jurgen in more than a year -- he sent over a romantic card, a dozen beautiful roses and a dog biscuit. The dog biscuit was humiliating, but the roses were wonderful. I missed Jurgen. He was difficult to please, but he was the most exciting man I had ever known. I wanted to be with him. I made a covered dish of Jurgen's favorite beef stew, dressed the way he liked me -- in a short denim skirt and halter top -- and went over to his house. The dog was tied up out back and started barking loudly and straining on its chain when it saw me.

Jurgen hugged me and kissed me on the forehead. He patted me on the top of the head, jokingly. He said he was glad to see me. He sat me down on his sofa and poured me wine. We ignored the incessant howling of the dog as best we could as we talked. The dog was going crazy.

Finally, Jurgen went outside. He had not said anything to me, but I knew he was letting the dog in. I could hear its nails clattering frantically on the tile floor in the kitchen, and those damn tags jangling. I tensed. The dog yelped and made a beeline for the living room where it smelled me. The dog was beside itself with excitement. Its stub of a tail was wagging wildly. Diesel's ears were up and the dog was whining and shaking at the sight of me.

"He's glad to see you," Jurgen said calmly. "Diesel missed you."

The dog moved on me immediately, burrowing its snout up my skirt. Its wet nose pressing against my thighs. With its muzzle in my skirt, the dog started growling menacingly and nipping at me. I was terrified.

"It knows what it wants!" Jurgen said, smirking as I cringed, shrank back and parted my legs, afraid of being bitten by the frantic animal. It got its teeth into my panties and began shaking its head, backing away, tearing my panties right off me.

"I taught him that while you were away," Jurgen said proudly as the dog burrowed its snout back up my skirt, its rough tongue now licking at my vagina. Tears of humiliation streamed down my face.

The dog gripped the hem of my skirt in its jaws and dug its claws into the carpet, straining as it backed away, tugging me off the sofa and toward the floor. It was growling, its teeth bared. I looked to Jurgen for help, expecting him to call off the dog with a few harshly spoken German words. Jurgen said nothing. He just watched with an amused smile on his face. Our eyes met and he just shrugged.

"Say something! Make it stop," I whispered pathetically. "Call your dog off me!"

"I am not getting involved. This is between you and the dog," the man I had loved so fiercely said just before he turned his back on me and walked out of the room. As the dog used its power to drag me onto the floor I heard the refrigerator door open and the unmistakable sound of a beer can being opened. I had twisted around as the dog dragged me from the sofa and I was on my hands and knees, trying to get to my feet and the dog had worked itself into an absolute frenzy. The dog's snarling face was inches from mine. Its lips were back, its teeth bared. Saliva dripped onto the carpet. I was shivering with terror.

"If you don't want your throat ripped out in the next ten seconds, Julie, I recommend you slowly lay down on your back. Very slowly." Jurgen's words were calm and softly spoken. I had no choice. I did as he said, going onto my back in slow motion. The dog was still snarling and baring its teeth inches from my face. The hair on its back was raised. Its ears were flattened. I was in trouble.

"Offer it your throat, Julie."

I didn't move. I thought about the woman jogger and her four hundred stitches. I tried not to imagine what that must look like. Four hundred stitches. I thought about the teen-age boy who had been mauled just the other day. I tried not to think about that snarling dog baring its teeth and slobbering in rage at me at that moment.

"Offer the dog your throat. Show him you are submitting. If you don't, you will be torn apart. I know what I am talking about."

I raised my head, presenting the angry dog with my throat. I couldn't stop shaking. I was so vulnerable at that moment to a frenzied animal that was capable of killing me in a moment. When the dog's jaws closed down around my throat and growled I peed on the carpet. I knew I was dead. But the dog did not bite down. It held my throat in its jaws and growled.

"He just establishing its dominance, Julie. That's its nature. If you are going to survive, you must be totally submissive," Jurgen said. "The stud dominates the bitch. Welcome to the animal kingdom."

When the dog finally released my bruised throat, Jurgen told me to lick its mouth. "That is all submissive behavior the dog can understand," Jurgen told me as I desperately lavished the dog's mouth with my tongue.

"You have to understand Diesel will never tolerate any sign of equality or dominance from you. Do you understand? This is not a poodle. You must be totally submissive to it. Or suffer the consequences."

As Jurgen calmly sipped his beer, I obeyed every instruction he gave me and carefully wriggled out of my damaged skirt and torn panties, slipped out of my halter and got back on my hands and knees, presenting myself to the eager dog. It mounted me with urgency.

"What Diesel wants, Diesel gets!" Jurgen said smugly as Diesel got me. "Good dog, Diesel!"

After the dog had ejaculated inside me and its cock swelled to fill my womb, Jurgen got up and turned on the television set, clicking restlessly through the channels.

"You should be grateful," he said to me while I knelt back-to-back with his dog, my head resting on the floor, enduring the "tie" that follows mating, waiting several long minutes for that dog's cock to shrink enough to slip out of me. "People pay me a lot of money to let Diesel fuck their bitches. You get it for free."

When the dog's penis shrank and slipped away, Jurgen gave the dog a cookie and a big hug, rewarding it for what it had done to me. I knew he was training the dog, teaching it that by fucking me it was pleasing its master. That was powerful motivation for Diesel. In fact, it was what motivated me, too.

Jurgen told me things between us could never be the same. Yes, he loved me, more than ever. He said I never looked so beautiful or sexy as when I was with his dog. Not many women would do that and I was special. But he did not want to confuse his dog. I could no longer be his girlfriend, I was now the dog's bitch. And like Diesel, I was Jurgen's pet. But in the dog's world, a bitch is a bitch, and I rated beneath both males in that household.

Jurgen never let me forget what I had done. I had let him push me too far, farther than he could stomach himself. He would scrape food into the dog's bowl and make me eat on the floor next to the dog, calling it a romantic dinner with my lover. I was there to serve at the dog's pleasure only. He joked cruelly that I might have a litter some day. He called me a brood bitch.

When he had his next ritual with Diesel, making the dog present his paws and muzzle to Jurgen, he had me kneel down next to him and had the dog sit close to me. After he went through the ceremony declaring the dog's paws and muzzle to belong to him, Jurgen placed the dog's paw against my lips and told me to lick it. When I did, Jurgen announced in his most authoritative voice, "Diesel's bitch." He had me sit still while he had the dog's paws rest on my shoulder and he repeated the announcement, "Diesel's bitch." It was official. For Jurgen, and for the dog, that little ritual carried all the authority of a wedding ceremony.

Things were different. The way the dog looked at me after that. It always wanted ME. It was humiliating to be wanted by a dog. Jurgen made me walk the dog at night. Jurgen called them "romantic walks" with my lover. I never took the dog on those walks, the dog took me, straining its massive weight on the leash to set the direction and pace. If I lagged behind or started off in the wrong direction, the dog would snarl viciously. It was clear who was dominant in our relationship. Diesel was the alpha dog. On those walks, Diesel would go wild if another dog came near me. He would lunge at it, snarling viciously, its teeth bared. It would not allow any other male dog around me. It was jealous, protecting its property.

Jurgen said the dog was his best friend and he always let me know he loved that dog more than me. He said the dog only loved its master, not me. Jurgen said the relationship between Master and Dog was so strong that no bitch would ever come between them. If Diesel were ever to injure me, Jurgen said he would not hesitate to let me bleed to death and dump my body rather than risk his beloved dog being destroyed. That chilled me, but I had no reason to doubt him.

Jurgen would no longer have sex with me. He said he would not put his cock where a dog's cock had been. He said he did not fuck dogs. And I was a dog now. I was beneath him. He would not even kiss me. We did not go to the movies or out to dinner. I was hurt. I had not given up my dream of marrying Jurgen. He is an unusual man and I tried so hard to be the unusual woman that he would want.

"You don't understand dogs. They are very simple. Obedience. Loyalty. Courage. He thinks you are his now. You are his now. Think of it from the dog's perspective. If I made love to you now, I would become his rival. It would ruin our relationship. Diesel's and mine. He would not trust me. I'm his master. He would be confused."

When I protested, saying we could make love at my apartment and the dog would never know, Jurgen said it would smell his scent on me and feel betrayed.

"That would be unfair to the dog," he said, closing any further discussion on that topic. "And by the way, from now on, keep off the furniture." He was serious. I was not allowed to sit on the sofa, lay on his bed or eat at the table ever again. After all, what would Diesel think?

While cleaning the bedroom I found some Camel cigarette butts with telltale red lipstick marks in the ashtray on the nightstand. That was the brand Jurgen's old girlfriend, the one with the bleached blonde hair and rose tattoo, smoked. That confirmed my suspicions. I had smelled her perfume on his pillow case when I did the laundry, but I was still devoted to Jurgen and even though it hurt, I continued doing everything I could to please him.

Jurgen wanted to keep his precious Diesel on a regular schedule so it would continue to perform for what he called "the paying bitches."

Jurgen decided when I could see him, and his dog. He insisted that I come over to his house twice a week for "dates" with Diesel, never more, and never less. He made me dress up for those dates and he trained the dog to "ask" him before it mounted me. And I was instructed to come over four evenings a week to walk the dog. When I was at Jurgen's house I was there to see the dog, not him. And the dog and Jurgen decided if there would be sex. Once the dog decided, there was nothing I could do. I was not allowed to say no. When that dog stuck its nose in my crotch I was expected to be completely pliant. But Jurgen kept tight limits on my visits.

"If the dog had his way, he'd be fucking you ten times a day! You'd like that wouldn't you?"

He made me say yes.

From then on, my Saturday nights belonged to Diesel and Jurgen. Instead of sex with me the way it used to be between me and Jurgen, Jurgen would have me wear a sexy nightie and have me lay on floor and let dog into room. He would sit on the sofa and watch it fuck me. The dog had a ritual of sniffing me, growling and licking my face before it mounted me. Jurgen always rewarded with praise and its favorite cookie. I learned the German command Jurgen uttered before the dog mounted me that first time was "Get girl", the command he gave Diesel when it was breeding a brood bitch. After that first night, though, Diesel did not need his master's command to mount me.

As we got more comfortable with each other as lovers, the dog and I found new positions, and it would take me on my back and fuck me in the missionary position, its paws on my shoulders, licking my face with its big red tongue, biting my throat and growling as it jabbed its penis into me. Just like a wife grows accustomed to her husband's preferences and manners in bed, I got quite familiar with the dog's rituals and habits. I could sense when it was about to ejaculate inside me. I learned that by pressing myself back into him, I could relieve some of the pressure from the heavy dog's humping into me. And I developed a technique of resting my face and one elbow on the floor when I was being mounted so that I could free one hand to press against my vagina to protect it somewhat. The massive dog outweighed me by more than twenty pounds and when it got really going on me, of course, it was more than I could support and he would break me down beneath him.

As a lover, the dog was unlike any man I had known. Diesel was a quick, powerful, dominating lover, and it was never satisfied with just once. It had to have me at least two or three times before it would leave me alone. The dog always left me scratched and sore, aching and thrilled.

Jurgen made me talk to the dog the way I had talked to men in bed while it mounted me, whispering that I loved it, encouraging it, whispering come on, love, the way I used to talk to Jurgen in bed.

I also became more skilled at playing with the dog's penis, learning to lure it out of its sheath so that I could kiss it, suck it's long, crooked erection and lick the reddish bulb at its base. Jurgen was thrilled when I actually succeeded in making the dog come in my mouth. The dog's come was more fluid and pungent than the men I have tasted, and its three powerful ejaculations produced more come than I could swallow. Jurgen was thrilled by the lewd sight of his dog's come drooling down my chin. Jurgen said there were not many women that could do that with a dog! After awhile Diesel liked me doing that so much the dog would sometimes demand I suck its cock on our dates rather than mate.
