When I was younger, I was out in the pecan orchard that we had behind our house. I was probably 14 or 15.. We had a very large german shepherd male and I remember he was walking around and came up to the tree I was under, sniffed around at the tree and lifted his leg and pisses on it to mark it. I remember that turning me on, seeing him act all alpha and pissing on that tree, When he was done and he let his leg down, the very tip of his red cock was poking out of the furry brown end of his sheath, dripping a lil. He walked over to me, My eyes still on him, I watched the way his big heavy black balls swung, and his big furry sheath kinda swung side to side, but the red tip of his cock had slid back up inside his sheath.
When he got to me, I found myself petting him, and then reaching under him and rubbing his sheath, I was so turned on I couldnt believe what I was doing, but I couldnt stop, it was so sexy. To my surprise, when I started rubbing his sheath, that red tip of his cock came sliding back out, and I could feel the base of his sheath swelling, getting bigger and I could feel the beginnings of his knot through the sheath. To my surprise he started humping my hand in a really powerful way, and with his cock only just partially showing now it was already squirting, dripping through my fingers. I stopped.. and he calmed down and I watched his red cock tip slide back into the sheath. He was really interested in me now, and kept circling me, and sniffing me. I remember I had some blue stretch fit shorts on... I didnt even know what I was doing, but I made sure no one at my family home could see me by going further into the orchard and behind a big tree, and got on all 4s... I waited just to see what would happen. He didnt mount, but he came over and started sniffing at me, licking my butt, then my face, then my side, he kinda tried jumping up onto my rear to mount but was clumsy and missed. I encouraged him to try again and helped him this time by holding his paws. To my surprise, it's like he knew what to do next naturally.... He gripped those big paws into my thighs, and arched his back and began humping around my butt. I didn't know what to do, this was my first time, but he kept squirting pre cum this really thing copious clear cum all over my back and my butt and thighs. Eventually when he tried again, I reached back and with his sheath in my hand, gave him a good jerk until his red cock slid out of the sheath, then I guided the tip of his cock to my ass, and to my hole. I got really turned on when I felt the wetness of his pre cum touching my hole, and the tip of his cock I remember was REALLY warm, hotter than my body temperature.. what happened next I was not prepared for.
He gripped onto my thighs really hard, digging his claws into them, and began hammering at my young hole, at one point the pointy tip of his red dick hit the edge of my hole with such force it hurt, and then suddenly he slipped into me. I'll never forget it... the second his warm red cock tip was in me, he must of felt it and just knew what to do.. He began to hammer it deeper into me, and In and out very violently. At this young Age I didnt really know about the Knot or exactly what it was or why dogs cocks looked that way, but he was humping and fucking so violently that his whole red dock cock was in me all of a sudden, the fur from his sheath rubbing against my ass, and he must have shoved all the way in before the knot began to swell because without warning I began to feel him swell inside of me. It happened so fast, and I acrtually moaned and cried out loud as his knot swelled up to its full size inside me as he kept humping and fucking me. I got kind of scared because the pain was so bad, and I started worrying what would happen if he was too big for me, and maybe he could hurt me. But it was too late, his knot had tied me and he kept fucking and fucking my ass. I whimpered and as hot as it was I fearfully tried to pull away from him I just couldnt take how huge is knot was inside me.... but it was too late. He gripped me and kept humping in shorter thrusts but fast, because his knot was tied to me. I cried out, and again tried to crawl forward away from him but he just pulled closer to me and kept that humping motion as I tried to get away from him. Eventually I began to grow a little used to the knot and stopped trying to pull off him, but even when he stopped humping and i could feel his cock and knot pulsing as he came inside me I started to get scared. How long would I be stuck like this? What if one of my family members came out there... After a few minutes I tried again to get off of his knot and dick, and he wasnt having it. He gripped my thighs hard and panted in my ear as his dick kept pulsing every second or so, unloading in me. I was nearly crying but just gave up trying to get him off of me, and rested my forehead in the grass, with my ass knotted and tied until suddenly he jumped off of my back and spun around with his dick and knot still inside me. I remmeber the feeling of his knot and dick rotating inside of me, and that there was now clear and white cum running down from my ass hole, onto my balls, and down my dick, dripping and dripping onto the ground. This went on for what felt like forever until eventually I felt his knot begin to slip out, and when he did i cried out from the sudden release of that massive canine knot and cock, and a whole lot cum ran out of my ass and down my nuts and cock. I had my forehead in the grass and was looking under myself behind me to see, that was the first time I saw his cock fully hard and knotted now that he had pulled out. I couldnt believe what had just happened, and that I had been bred by my boy with that massive thing. I briefly worried if I would be bleeding internaly, but Just cum was dripping from me. His dick stay huge and swinging under him as he panted and walked around me. I hadnt intended for him to fuck me, I mean I didnt think that could really happen I was just being bad, and curious. and even though I had felt his knot swelling a little when I jerked him, I had no idea how big a canines knot could get, or that it would tie your ass to him leaving you at the mercy of a horny beast, pumping you full of cum. I was kind of scared of what happened, and I was shaking.
After a couple of days, I wasnt scared anymore, and I took my german sheperd (his name was bear) and our other male dog a husky (named frank) for a walk in the woods. this Time I encourage my black and white husky male to mount me, but while he was attempting it... bear came over and snapped at him and they scuffled for a second, then bear came to me and sniffed and licked at my hole. He didnt try to jump up and mount me by himself but everytime my husky would come near, he would growl threateningly. He was showing his alpha male instincts I realise now, so I reached back and encouraged him to breed me again and this time was so much better. I was not so scared and I moaned loudly as he filled me up over and knotted me, then came inside for about 15 minutes.. when he was done, I did the craziest thing, and called frank over, showing him my dripping hole, and reaching back i jerked him, bear at this point was off to the side with his knotted cock swinging from his sheath and panting loudly he was worn out... so frank was able to slide his red pointy tip into me and proceeded to take his turn fucking me. I remember I had trouble knotting with him, his knot would swell up to full size before he would really get his dick up in there and start humping. I had to let him off me a few times and his knot go down, and try again until finaly he jumped onto me and shoved his wet red dock cock in me really fast and accurately that time and as he was humping his cock into I felt his knot swell up and tie with me. His knot was not as big as bears, and so the pain was a lot less. I moaned so loud, and pushed my ass back against him when he felt like he might slip out.. more cum ran down my balls and cock as he took his turn breeding me. After about 10 minutes, and stopped squeezing my ass hole onto his knot and let him slowly slip out of me, a massive amount of dog spunk gushed out, and the two of them (my dogs) took turns sniffing each others cocks. It was so fucking hot to look at the both of them and their two swolled cocks and knots and know that I had just taken both of them and been bred by them, the whole thing was so hot i didnt even realise i was dripping pre cum of my own, so I began to jerk off but i barely lasted 10 seconds and I came so much more than I ever had before.
This was my first experience.... certainly not my last. My father had hunting dogs, about 6 or 7 of them at our hunting camp that he used to hunt rabbits. I once got into their kennel and let 2 of them breed me, I tried to let another of the dog pack fuck me and he did but he couldnt seem to knot me at the right time. The same thing happened with the fourth dog I tried to allow to breed me, but it was still really fucking hot.
