| This story was on a hard drive in a second hand computer I bought so I can't take responsibility or the credits for writing it. I hope you enjoy.There is more if any member is interestedThe Shape Shifter In the beginning I was a normal young male child with what I seen as a protected life which I feel caused me to be secluded later on in my teens, growing up with only two other friends through out elementary and secondary, all the way to high school. Being sexually aware teens we would be ogling the females in the school but we would never allow our discussion out of our group due to rejection and ridicule from the females and their friends, this set the stage for my urges a little later in life. I grew to be a still secluded but fully-grown brown eyed brown haired 6ft tall man with an over active sex drive that with no real outlet caused me to look for other means to relieve myself. In the years to follow I would try to relieve my sexual urges in any way I could usually I would use the proven method of relief with masturbation but I found this became less exciting as time went on. In turn this caused me to look for another type of relief but I was still to shy to date, in my mind females were the Holy Grail I had to cross a sea of misery to obtain. I continued on with my life regardless of my urges and became a honour student in genetics in my mid twenties, I continued in this field until I was rejected by the scientific community due to my experiments with genetic manipulation. This forced me to continue my experiments in a more private location; my goal was to create a non-specific genetic pattern that would allow myself to change my skin texture, height weight, and my true goal to change species. I had realised in my earlier years that animals had an advantage over humans, they had no elaborate mating rituals as humans have, for them if your bigger you get to mate. This intrigued me for I would be able change species and from there adjust my body to the needed dimensions or other factors to achieve breeding rights. This seemed to me to be the solution to my problems by allowing myself to be drained of my urges then return to my human form. I would continue my experiments for another five years until finally I succeeded I created a solution that once injected allowed me to become a shape shifter. I was delighted, I took a long deserved sleep, once I woke I realised what I succeeded the night before. I was ecstatic with the possibilities and realised I would have to try it out. I returned to my lab and impaled myself on the syringe. I would have to find out how to activate the genes in my body. At first I attempted to change my skin texture and after a few days of practice I mastered this field. Changing texture or colour was a snap for me. I continued on to morphing my body, this proved to be more difficult but after a week this as well came to be an easy task, I could chance height weight and slightly my shape I truly enjoyed this. This did still not satisfy me and I continued on with species changing, I would concentrate and after a gruelling hour I shifted into a dog this was the moment I was waiting for I had achieved my goals. I bound and leaped in excitement but I had realised I had to go outside to find other dogs, but to my distress I was locked in the house. I tried to shift back but nothing I truly was worried would I be stuck like this, will I starve who will feed me, due to my solitary life no one knew what happened to me. A long five hours later I changed back with little effort then I realised what may be happening I can only change once every five hours and days later my theory was without a doubt proved to be correct. After a few alterations to the doors on my home I was ready, I changed back into a dog and set out to the neighbours which was a farm with many types of animals and a few dogs once in the far yard the dogs came to see me. After a smelling and licking session I was ready to go I then realised that one dog was always behind me and a male at that I wondered what his problem was, as I approached the females hoping for a f**k the male jumped on me. This scared me I knew what he was trying to do but I didn't want him in my ass. It was then it dawned on me as I looked back between my legs, I realised that I was in the form of a female dog and in my excited state it left me smelling like I was in heat. This male was trying to breed with me. I tried to move away from him without success and he bit my neck as if saying "oh no you don't your mine" as he humped his haunches into my hindquarters. The one thing that I hadn’t counted on was the fact that once I changed my shape I was instantly on heat. I felt his pointy penis push upward trying desperately to find my swollen furry slit. As he entered my slit it was something that was totally foreign to me, as he shoved his cock deep into my hot wet slit. I liked the feeling and I pushed back to meet his thrusts, with each thrust his penis grew a little in length and size I loved every second of it. An unfamiliar feeling was growing in my pussy, it was like nothing I had felt as a male, it was slightly similar to the orgasms I had as man, but it was different it was stronger and more concentrated. I rocketed through that orgasm as he continued humping away at my pussy. By now his penis felt huge inside my pussy and to my surprise it all of a sudden it felt even bigger as his thrusts pushed this lump into my pussy. I howled loudly as he locked into me. My pussy felt totally filled it was incredible, the feeling of his penis throbbing inside of my new pussy. My new lover’s penis was locked deep inside my pussy as I felt his penis start to expand even more as he rewarded me with his seed squirting deep inside my pussy, this drove me over the top once again. I felt faint from all the pleasure but it soon subsided and I was marvelling at the experience I had felt with this dog and I knew from then on I would never be the same. I left my new lover a half hour later when his knot was removed and he was satisfied with his handiwork once I reached home I realised I had another three hours till I could change back so I figured that I could go looking for more potential suitors. I continued down the road until another friendly farm dog greeted me this one was even larger that the last. His reaction to my smell was instantaneous, he knew I was in heat and he wanted some of the action. He was sniffing and licking at my pussy, less than a second after he stopped he mounted me and rammed his penis all the way into my waiting pussy. I quickly realised I may have gotten myself way in over my head due to the length of his organ. His penis was so long, I didn't think he would get his hardening knot into me, his knot hadn't touched my pussy. Pulling back, he gripped me tighter, his forward thrust so powerful, he almost knocked me to the ground. As he shoved his penis all the way into me. I thought his knot would just hit my pussy lips and bounce there. Luckily his knot wasn't fully hard. His hairy sheath slammed against my pussy and as it did his thickening penis ploughed its way deeper into my pussy. His penis suddenly expanded to its full size. The waves of pleasure that washed over me was giving me orgasm after orgasm. His knot slammed against the opening to my pussy. I was in heaven with the pounding I was getting so I didn't worry. His knot felt like it was the size of a football as it kept hitting my pussy. The pounding he was giving me was making my pussy explode with my juices. His final thrust was so hard that my pussy opened up and allowed his knot to enter me. His powerful thrusts were creating an incredible the feeling. My opening widened with the pounding I was receiving finally forced his knot inside me. As my pussy closed around his knot, it swelled and hardened so much that I was howling with pain and passion all at the same time. As I calmed down, my lover made his final thrust and as he came, he turned on me and we ended up ass to ass like most dogs do. The thickness of his penis and the amount of cum he was shooting into me was stretching my dog pussy to its limits I was loving it all so much I never noticed the owner watching us. As he finished coming inside me and I ended up looking straight up at his owner, she was beautiful long blond hair, blue eyes so naughty looking. Her body was incredible long legs shapely hips slim stomach huge breasts and a voice of an angel. "I am glad some one else decided to help me satisfy him," she said, while she was patting my head. I was dumb-founded did this mean that she would have sex with this beast? "He sure has you filled up tight doesn't he," she spoke. "Well at least he didn't rough you up too bad. Not like he normally does." I couldn't get away so I stayed there and listened to her until my lover pulled out of me with a wet pop and I was free I watched with amazement as this beautiful blond dug some cum out of my stretched pussy and sucked it in to her mouth. This had me watching with undeterred concentration that when she finished with that hand full she took her lover and left but stopping and saying. "Do come back now you hear," in a naughty voice. I made a beeline for home once safe inside I changed back to my original form this was a day to remember and I swore that I would take her up on her offer. When I reached home I realised I had another three hours till I could change back so I figured that I could go looking for more potential suitors. I continued down the road until another friendly farm dog greeted me this one was even larger that the last. His reaction to my smell was instantaneous, he knew I was on heat and he wanted some of the action. He was sniffing and licking at my pussy the whole time . The second I stopped he mounted me and after a couple of quick thrusts he rammed his penis all the way into my pussy. I quickly realised I may have gotten myself way in over my head due to the length of his organ. His penis was so long, I didn't think he would get his hardening knot into me, his knot hadn't touched my pussy. Pulling back, he gripped me tighter, his forward thrust so powerful, he almost knocked me to the ground. As he shoved his penis all the way into me. I thought his knot would just hit my pussy lips and bounce there. Luckily his knot wasn't fully hard. His hairy sheath slammed against my pussy and as it did his thickening penis ploughed its way deeper into my pussy. His penis suddenly expanded to its full size, it was a good three inches in diameter and I was loving every inch of that beautiful penis. The waves of pleasure that washed over me was giving me orgasm after orgasm. His knot slammed against the opening to my pussy. I was in heaven with the pounding I was getting so I didn't worry. His knot felt like it was the size of a football as it kept hitting my pussy. The pounding he was giving me was making my pussy explode with my juices. His final thrust was so hard that my pussy opened up and allowed his knot to partially enter me. His powerful thrusts were creating an incredible the feeling. My opening widened with the pounding I was receiving finally forced his knot inside me. As my pussy closed around his knot, it swelled and hardened so much that I was howling with pain and passion all at the same time. As I calmed down, my lover made his final thrust and as he came, he turned on me and we ended up ass to ass like most dogs do. The thickness of his penis and the amount of cum he was shooting into me was stretching my dog pussy to its limits I was loving it all so much I never noticed the owner watching us. The beautiful woman was going to willingly get f***** by that huge dog. I was watching her go at him dumbfounded as she guided him on to her, his penis was big and red but I knew it would get much bigger before he was done with her. He wanted to push his penis inside of her, but was bouncing off her ass so she reached back and helped his aim and he jumped forward sinking his penis inside of her while she groaned with lust. The dog started to pump his penis as deep as he could into his lover all the time she was yelling, "yes, yes f*** me hard oh yeah!" I could see his penis had grown twice its size already. His knot was already well pronounced, but was still not up to her lips yet; Ralph was still pumping his penis inside of her and was growing in size and length with ever thrust. Brenda was in the clouds moaning and pulling at her erect nipple then with her other hand started to rub her swollen clit so I decided I would help her and got beside her and started licking her pussy with him pumping into it. This effect of pumping and licking started to send her over the top she came a good three times yelling out and bouncing back into his thrusts. I could see Ralph's penis pumping in and out of her pussy with the knot know full size bumping against her pussy lips this was sending waves of pleasure through her body. The dog’s knot was huge like the size of a foot ball and it was pushing against Brenda's pussy lips, to help it slip in I began to lick it to lube it up to slip in to her pussy which made him pump even harder. Slowly it slid forward stretching her pussy lips wide Brenda began to scream with pleasure he was pumping so hard that it all of a sudden plopped inside of her hungry pussy which sent her cumming once again. Once Ralph was in here pussy he just kept pumping as hard as ever which was making Brenda's pussy lips suck in and bulge out with every thrust of his penis, that sight of her pussy moving in and out with him sent me over the top. After I calmed down I began licking her pussy again and I was rewarded with Brenda's and Ralph's love juice I gladly licked them clean once they were done he turned ass to ass with her making her cum again. Once she calmed down she called me over and began to massage my pussy lips and sent me through three more orgasms, after all that we all just relaxed and a little later Brenda's plugged pussy poured the trapped cum out. After that experience I was absolutely soaked I was so horny my pussy seeped a constant river of fluid that the dog was picking up on and was gathering himself for another go Brenda was continued to relax in the corner as we started again. He gave my pussy a nice sniff and was sure I wanted to get bred again so he jumped on my back and started to search out my pussy with his extending penis. I could feel his tip poking at my pussy and he slowly pumped his penis inside of me his motions now matching mine thrusting his penis as deep as he could. His penis now full size I began to feel that familiar feeling his knot was beginning to bump on my lips as he would thrust it deeper in to my hungry pussy but as I looked toward where Brenda was sitting she was gone. As I scanned the room I seen her over by the horses where she was rubbing the sheath of the huge animal and to my surprise it was humping her hand while its penis still was growing. Brenda got down on her knees and started to rub that three-foot long penis on her breasts rubbing all the precum into her tits the sight was so hot I came with Ralph's penis buried deep inside of me. As Ralph was pumping in my pussy his knot was slipping inside due to all the juice I was spilling then the satisfying plop of his knot slipping inside, I came right on time to see Brenda's lover shoot his cream on her tits while Ralph was shooting his seed inside of me. The feelings and sights were over whelming to cause me to cum and cum over and over again, after Ralph and me had finished we went out side to see Brenda again, she was laying in the sun on the grass naked covered in horse cum. So we laid down beside her as she dried after she finished I decided I would leave them alone now so I slipped away to my home down the road. I decided right there and then I would become a horse for my next evolutionary jump in my sex adventures and I would have to learn why I couldn't change into male animals because I was eager to explore that angle of these escapades. |
