My first time was shortly after my dad, uncles and a few of their friends had finished having their fun with me, I was laying in a pool of their cum on the floor, when one of their dogs came in (A german shepard), didnt notice at first but he gave my cum covered thigh a long lick which shocked me and made me stand up really quick. By the time I had caught my balance and realized what was happening his cock was out of his sheath and it just mesmerized me, he used this opportunity to nudge me which made me fall onto my hands and knees, not wasting anytime he mounted me and quickly found his mark, shoving his cock as far as he could into my pussy, which was still pretty full of cum, which made for good lubricant. This was the first time sex actually felt good, since all the times previous was with limp dicked pedos. I got so into it that I was drooling all over the floor, and I had pretty much loss all body function, was just a slab of breeding meat for him as he jack hammered his big doggy cock deep inside of me over and over again until I felt something big start to pry my pussy lips apart thrust by thrust. Before this moment I had never even thought about bestiality or seen a dogs cock so I had no idea what was coming next, and thats when he managed to shove his knot past my pussy lips and thoroughly wedging his doggy cock deep into my pussy. This of course made me cum like I had never cum before, my whole body was twitching and shaking from this massive orgasm, all while my lover shot load after load of his cum deep into my pussy <3. I was completely out of it when I heard "Come here boy, come on" followed by a loud whistle. The dog hearing this turns around so that he's ass-to-ass with me and drags me along the ground towards my door, the mixture of pain and pleasure causing me to cum over and over again. Because of the resistance of dragging me on the ground, the dog stopped for a few moments. This was enough time to allow me regain my senses and realize that he had dragged me halfway across the floor, from where he had initially mounted me, and we where now right infront of my half open door. I tried to slowly crawl away from my door, holding onto his hind legs to try and get him to move with me. But just as I did this, his owner called him again and this time he was insistent on getting to his owner, and after he nudged the door open and was dragging me through the doorway, I grabbed onto the door way and held tight so that I wouldnt slip, eventually he stopped trying to make it through and waited till his knot swelled down (luckily nobody walked down the hallway), and when he was finally shrunk down enough to pull out he did it with a loud pop, and a torrent of doggy cum went leaking out of my pussy.
