Sam and I sat inside the club house cooling down in frustration while a young couple came into the clearing surrounding the houses and started necking and fondling each other. It wasn't long before their clothes started coming off. They were getting pretty intense when the girl said they had to find some shelter. Luckily, there was a clubhouse close to them and they went inside it rather than the one we were in. Watching this was driving me crazy. After a few minutes I could hear moaning.

Sam and I slipped out and headed down a path with Sam's nose firmly buried in my crotch. I found a grassy area and got on all fours. There was no way that I was going home without getting Sam's cum blast in my pussy. We had enough privacy to finish what we started but not to enjoy each other the way I had planned. This was now going to have to be a quickie.

Sam mounted me and we went at each other with fury. I did every thing I knew to do to bury his cock deep inside me and he was pounding as hard as he knew how. It certainly wasn't the dream I had, but screw it I had to have his cock. We pounded at each other for several minutes before I felt Sam tense his muscles and drive hard. I pushed back just as I felt the first blast of cum shot from the tip of his penis. On the second or third blast I came hard. At that moment I realized how hot his cum was. I was feeling the glow of my own orgasm and the warmness in my vagina from his cum.

Sam was trying to push his knot inside me. Oh, how I wanted it inside and feel it swell, locking us together. But I couldn't risk it. We walked home with his cum dripping down my legs into my tennis shoes. It wasn't the ecstasy I had dreamed of, but it served its purpose. At least I would be able to sleep. We still needed privacy to fulfill our fantasies.

The next night I awoke at 2:30 am and slipped out of the house to the garage. Sam and I went at each other aggressively. We were afraid of Beverly walking in on us again that we didn't take our time. Once we started fucking it seemed like there was so much built up sexual tension between us that we had to fuck and fuck and fuck just to get it out of our system before we could really enjoy each other. I have never experienced such a sexual lust that I have for Sam. We made continuous love to each other for over an hour. I mean we both had orgasm after orgasm and we didn't stop pounding on each other. There were no rest periods, pounding from one orgasm to the next without stopping.

Finally we both came together and just collapsed on the floor of the garage. We never locked. Our sexual tension was gone but our fantasies still remained unfulfilled. I needed complete privacy for at least one night so that I could become Sam's bitch. My pussy still yearned for Sam. The intense wanton feeling for him to pound me full of his cock and then drive his knot inside me, consummating me as his bitch, was still overwhelming.

The next day Beverly gave me the best news that I could wish for. She was going away for the weekend. It couldn't have come at a better time. She was leaving Friday and wouldn't be back until Monday.

On Friday, it was all I could do to stay at work. I did go home at lunch and find Sam. I brought him home and we petted heavily before I had to return to work. At 5:00 I blasted out the door and went straight home. Sam was in the back yard waiting for me. We went in and straight to my bedroom. I undressed for him and he licked me as I removed my clothes. I got my skirt off first. Sam had his head in my blouse searching for my breast. My nipples were like rock hard bumps when I got my blouse off. Sam has this way of getting his tongue down in my bra and licking my entire breast with one long slurp. My body shuddered with delight as his glorious tongue moved over my flesh awakening every pore in my skin. Not only did my nipples get hard, but the small bumps around the edges of my areola got erect too. You can see every one of them through my bra. I just stared at them in the mirror in total bliss. He made several passes at each of them.

I got so weak in the knees that I had to lay down on the bed. This was finally our moment. After the lustful sex we had several nights ago, we were more relaxed but the burning passion was still driving us. This was a long and wonderful evening of passionate lovemaking. I finally consummated with my lover.

I have stared for so long at his blue knot that my groin ached for the need to have it buried deep inside me. As I lay on the bed Sam came over me. We kissed for a few minutes before Sam slipped down and began to lick my wet pussy through my panties. I slid them aside for him. His tongue immediately slipped deep inside me. I responded by raising my hips to his face so that more of his tongue could find it's way into my being. I rocked my hips as he made tongue love to my canal. As I approached orgasm I pulled away and went after his cock. I took it in my mouth and stroked slowly savoring the taste of him. His precum started lubricating my mouth and our pleasure increased with every spurt. My taste buds were in overdrive from the taste of his skin and the taste of his precum. My tits were soaked with precum that drooled from my mouth. I got him close to orgasm and stopped. I wanted his first blast in my cunt. He licked the precum from my breast as we both let our pre-orgasm sensations subside.

I kissed him again and rolled over underneath him. I arched my back as I rose to my knees to meet his penis. I felt his hair on my back and slipped rearward to mate with him. His hair grazing across my ass raised goose pimples on my skin. My goose pimples seemed to explode as I felt the head of his penis searching the entrance to my pussy. He entered me by planting the first three inches of his cock inside my canal and then slid his hips forward slowly shoving the rest of his cock in my pussy. It felt so, so, so, good to feel him inside me. We both stroked slowly at each other. There was finally no reason to hurry.

I moved into him slipping his knot inside me. Man did it feel good slipping in and out of my canal. We continued our slow motion love making for quite a while riding the wave of growing passion for each other. As we fed each other our lust I could feel my focus narrowing. I was beginning to only be conscious of his cock. Nothing could take my attention away from making love to him and being loved by him.

Finally I had to have his knot. So I moved into him and pushed his knot inside me. I kept it buried inside me feeling it swell until it wouldn't come out any longer. I was so satisfied that I could lock with him I almost had my orgasm right then and there. I moved back and forth feeling his orange sized knot slide up and down the length of my vagina. Every time it crossed over my g-spot I shuddered in ecstasy. Sam was panting heavily.

I turned my head and took his tongue in my mouth, stroking and caressing it. Then I kissed his face. At his initiation, we started picking up the pace. Building, building and building speed. We were like two hammers going at each other.

Then I felt the first wonderful shot of cum. I had my own orgasm and shot my own cum on his tool. We both kept pounding as we shot our loads. Only when we were shooting dry did we slow our pace. I tightened my muscles clamping down on his knot and was rewarded by another load of his sweet cum. He moaned in delight with every shot. I looked between my legs and saw a wonderful stream on blood and cum oozing down my thighs. I had another earth shattering orgasm as my ultimate wish came true... I guess his knot took the rest of my virginity.

I was so, so happy and satisfied. I now knew how those women felt that night. The world could have crashed around us and it wouldn't have mattered. We would have kept making love to each other. How satisfying this had been for both of us. I licked him clean and we lay together on my bed for a long time. This is the best I had felt in my whole life. So, so fulfilled.

The next three days were continuous repeats of this first time. We made passionate love to each other resting and playing in between. It was our honeymoon. Every sexual encounter was a learning experience. We learned how to be more satisfying to each other. I couldn't have been more satisfied with Sam.

Beverly came home on Monday and our lovemaking had to go underground again. The best times we had were in the middle of the night in the garage by candlelight. Sam stayed in my yard almost continuously. His owner was beginning to be concerned, but I said that I really didn't mind having him stay. He was a good watchdog. Little did he know that I was Sam's bitch and he wasn't going to leave me, ever?

Wednesday night I slipped out again. Sam and I began to make beautiful love. Our intensity was growing as we refined our rhythm and technique. I had him locked in me and on the verge of a wonderful orgasm when the door of the garage opened. There was Beverly looking straight into my eyes. I was on all fours with Sam locked in my cunt. My eyes were half rolled back in to my head and I was thrusting at Sam with all I had.

She smiled instantly. She walked around us surveying the situation. Sam and I continued pumping. I was totally focused on orgasm and bringing Sam to climax it didn't matter that Beverly had found us.

Her first words were, "Wow! What took you so long?"

She got on all fours next to me and kissed me on the lips. She smiled and explained that she was a dog lover too. She liked Sam, but had her own lover further down the street. She just didn't know how to open the subject up with me. Beverly had arranged for me to witness the dog love at the party. She hoped that Sam and I would get together and then she could walk in on us and the whole issue would be out in the open.

She rolled on her back and kissed my breast while Sam and I finished our lovemaking. I came very hard and intense. Maybe it was the thought of being watched by Beverly that brought me off so hard. When Sam had shot me full she licked his cum from my legs as we waited to unlock.

Over the next week Beverly joined in on our lovemaking. She taught both of us a lot. She mated with Sam several times showing me how to regulate my rhythm to bring Sam off with more intensity and then showed me some tricks on how to use his knot. She showed me when to actually lock with him and demonstrated how to use his knot to milk every ounce of cum from Sam, heightening his satisfaction.

I licked her breast and Sam's cum from her legs as they finished. When she was through she remarked that Sam had come a long way since she had experienced him. Beverly also taught me how to start from a position on all fours waiting for Sam to really get turned on and when his knot first started to grow lower on to my shoulders placing my back at a steep downward angle burying Sam all the way inside my cunt. From this position I could feel his knot grow inside me until we were locked. I had several screaming orgasms just feeling his knot grow inside me from the intense pleasure generated by his knot. When we were locked Sam would then slam my head into the floor as he rammed himself into the depths of my love canal.

I was definitely learning how to be a dog slut and enjoy every last moment of being taken from behind. Beverly said if Sam had been this good the first time she encountered him she would have stuck with him. But she had found this big husky that just pounds her silly. So she has stuck with him. Beverly believes there is a certain animal magnetism that helps identify your mate. Once you find it you're hooked. Sam and I have it. She said that there are several other women in the neighborhood that have mates. She is planning a coming out party for Sam and I this Friday night. She is so pleased that I finally have Sam and all of this is out in the open. Believe me, I am too.

Beverly wasn't so bad a roommate after all. In fact she was going to be perfect. I can't wait till Friday night! I wonder who loves their dog the way I now love Sam? I hope that the yuppie single on the corner is one of them. There is nothing I wouldn't give to see her passionately writhing under the belly of her Great Dane.
