It was a long day at school, the first thing I always do when I get home is play with my German Shepard, Kovou. He’s a very large dog and weighs roughly 80 pounds. I would always get this strange jealousy when my friends came over and would pet him and play with him and he was so excited. Sometimes he even got a doggy boner and they were disgusted, it just made me laugh. I was currently in the shower and started to think about Kovou, about his boners and my fantasies of getting fucked by a dog. I got out of the shower with my towel and found Kovou waiting for me in my room.

I finally said to myself…this is it, you’re going to fuck a dog. I was still dripping wet from the shower. I closed my bedroom door and locked it, even though no one was going to be home for several hours. I removed my towel and laid on the ground beside him and started to pet him. He started wagging his tail and flopped onto his back for me to rub his belly. I slowly worked my way down to his dick, he grew hard under my hand. A shiny, red and pointed penis popped out of his furry sheath. It was a little wet and I started to stroke it, but when I touched it, he jumped up and looked surprised and guilty. “It’s okay, boy.” I said with a smile and he wagged his tail and stood in front of me, face to face.

He started to lick me and made his way down to my boobs and started to lick my nipples, wet from the shower. He continued to lick the water from my body with his large tongue, and finally, he found my pussy and started licking like crazy. I moaned with pleasure and gently petted his head while he ate me out. I backed up from him and thought about how I could get him inside of me. I decided I would do what would be easiest for him. Doggy style. I got on my hands and knees and reached back with one hand and patted my butt for him to jump on. He struggled a bit to understand but finally jumped on my back and tried to find the sweet spot to stick his huge dick into. He must have been about 10 inches long, not including the giant knot at the base. I felt his dick sliding across my right thigh. I tried to move my hips around to accomodate him better.

He humped really hard when I had moved into the exact right spot, and he went deep inside of me, filling me up with his cock. I screamed from the pleasure and pain of his member inside of me. I was dripping wet and was moaning his name. He was whining a little and I thought maybe I was so tight it was hurting him, but he just sped up and fucked me harder and harder that all I could do was hold on and try not to fall over with his weight. He pounded me so hard and fast it was unbelievable. I had never had sex like this with anyone else. He was hitting the very back of my pussy and there was never a moment that I wasn’t moaning. He started to fuck me even HARDER and I felt something large and hard hit the skin around my pussy. It was his knot. And he was trying to get it in. Oh no! That would NEVER fit. I tried to move out from under him but he held me down with his weight and paws. I managed to sit down and his cock slipped out.

I didn’t want to leave him unsatisfied, so I though that maybe my ass would be more forgiving to his knot. I held his dick as I returned to my position, and guided it to my ass. He immediately shoved it in. I had experienced anal before, but I was worried about the knot. I knew that the anus would stretch more than my pussy. He continued trying to push his knot in and I felt my ass giving in to it. Finally, it popped in and I screamed from the pain. Suddenly he stopped moving and I felt something warm inside of me. I knew he was cumming and it started to drip out and down between my legs. He tried to pull out but my ass was clenching from an orgasm. I never thought I could get an orgasm from anal. After ten minutes, his cock had gotten smaller and he slid out of me with ease. I collapsed and he laid behind me and licked our juices clean off my skin. When he was done, he laid beside me and I petted him until he slept.

I took another shower and went to bed early that night, knowing that we would do this again.

The next morning, I woke up and Kovou was standing over me watching me. I saw his cock already out and waiting for me. I stripped down naked and thought that we would do it on my bed this time. My door was wide open, so I locked it again like last night and returned to my bed. Kovou licked my pussy again, covering it with his saliva. His tongue went deep inside of me and I moaned. I covered my mouth, I don’t know who might be home right now. I let him continue as he licked my clit over and over again. I orgasmed and he licked up the fresh juices. I got on my hands and knees for him. He jumped on and searched for my sweet spot again.

I guided him into my pussy and he shoved in, HARD. I was sore from last night and it hurt even more than when he was trying to push his knot into me. I bit my pillow as the bed bounced, making our sex more intense. I was his bitch, there was no other way to put it. I felt his knot swelling against my skin. It felt as if it were bruising me from how hard he was trying to insert it. He was succeeding and I was screaming into my pillow. About a 3rd of his knot was already in and I was trying to get away from him, but it was to no avail. It was going to happen, until I was finally able to escape this fantasy and he slipped out again. Quick to return to my fantasy with him, I stuck my butt out and he found my anus quickly.

It seemed that his cock had shrunk a bit. He didn’t stop like he did last time. It was like we had to start all over again. I had never felt him fuck my ass so hard and fast. I heard and felt his knot pop in, but he wasn’t stopping yet. It more hurt more than anything, but there was still a pleasure to this pain that I couldn’t describe. About a minute later, he slowed down and I felt his cum inside me again. We weren’t stuck together this time, and my ass was gaping and sore. He licked me clean, and even stuck his tongue into my ass. He scratched my bedroom door to be let outside. I put my bathrobe on to let him out. I came back to my room and took a shower again. I would be sore for a few days now. Kovou would just have to wait. I called my best friend and told her what happened. I asked her if she wanted to try it with her dog, but she said she wants an experienced dog, like Kovou. I told her to come over this Friday and I would show her how good dog sex felt, and that I would train her dog to have sex with a woman too. That’s a story for another time, though.
