One fine day I asked my friends if I could take their dog Samson for a morning walk.

Why did I do this? It all started a week ago. A strange man had sent me a picture file online. On it was a beautiful young woman being fucked by a huge black dog. I had never seen anything like it before. I was so fascinated by it. That’s why I couldn’t think of anything else for the next few days. I eagerly asked for more of these pictures to be sent to me and soon the desire to try it myself sprouted in me.

Therefore, the time had come to not wait any longer.

So I called my friends and asked if I could take Samson for a walk.

When I picked him up I was so excited that I quickly said goodbye and ran down the street with the German Shepherd. I took him to my house and quickly closed the curtains and blinds. Since he knew me he was calm and trusting.

I knelt down in front of him and as I gently stroked him. He wiggled his rear end in delight. Playfully, I pushed him on his back and my hands wandered, stroking all over his belly towards his tail. Gently, so that he does not startle as I then massaged his balls and his sheath, he whimpered softly to himself. On the spot, his penis also already came to light. Hard, bright red, wet, and shiny.

I rubbed my hands with some oil and grabbed his wand. Samson stiffened a bit. He calmly allowed my caresses. My touches became more intense and also more powerful. I jerked his huge, hard, and especially fat cock with up and down movements. I also did not leave out his rock hard and like a small honeydew melon looking balls.

I think he knew what I expected from him.

Samson rolled onto his paws and flicked his tongue against my quivering labia. I sat down on the edge of the bed and spread my legs so wide that he could effortlessly put his head between my thighs.

He really didn’t need any more encouragement.

I lay down on my back and the dog licked my pussy like a drowning man for almost fifteen minutes. My God, I was dripping wet!

After that I looked down and saw his aroused thick cock again.

I got up, got a pair of thick socks and pulled them over his front paws. I decided to give him what he gave me. I lay down under him so that the tip of his cock was in front of my lips. I opened my mouth and his hot flesh went down to my throat.

At first nothing happened. But then he started fucking my mouth while I gave him a blowjob.

Almost immediately he squirted a watery liquid and what I couldn’t swallow ran all over my face.

I was afraid he would squirt in my mouth and therefore took him out again.

I wanted to feel his semen in my hole.

I lay down with my back over the edge of the bed again and called him to me.

He jumped up immediately, placed his front paws next to my ribs and thrust.

Samson hit my burning cunt on the first try (just thinking about it makes me horny again). Not once did I have to help him and God he fucked me really hard!

His paws really pressed the air out of my chest.

He held on to me while he pounded my cunt hole with his fat cock faster and faster. He whimpered and I thought to myself that this horny dog would soon inseminate his bitch.

I was so overwhelmed, that I pressed my ass against his pelvis with each of his thrusts. With my hands I had to support myself on the bedposts since he fucked me with such force that I would have otherwise slipped off the bed.

Then, all at once, I felt what I had forgotten, his knot.

My cunt was so slick by his pre-cum and my juices that he drove his knot between my labia and into my hole with an insanely hard thrust. I felt like I was going to burst and cried out in surprise, pain, and pleasure.

This only seemed to spur him on and Samson only fucked harder.

Before I even knew what happened, his knot was deep inside me. After one to two minutes this feeling was indescribable and I loved that he greatly widened my whole cunt while he fucked my brains out.

I could not withstand his brutal thrusts anymore and a huge orgasm drove through my body. I moaned and my vaginal muscles closed, twitching around his whole cock. Samson only quickened his fucking.

Then the dog came.

Again I climaxed, as he squirted his hot and scalding dog semen deep into my cunt hole.

He continued to thrust and his balls emptied into me. It lasted almost five minutes.

After that he just dropped onto my back and every time his horny cock twitched again it was like an electric shock went through my body.

After that he just lay still and I felt his warm semen sloshing back and forth inside me.

It took another fifteen minutes for him to pull his knot and cock out of my pussy. His cum shot out in a high arc.

I then held him in my arms and the dog lovingly licked my face and full tits.

He then went to the corner of the room a satisfied dog, lay down and cleaned himself up with his tongue!

I continued to lie exhausted in bed and was covered from top to bottom with his sticky juice!

His sperm ran out of my pussy hole onto my thighs and legs while my face and tits were covered with his fluids. I also had his animal smell in my hair and on my body.

I smelled and licked my own body and tasted the essence of my insane lover.

I looked over at him and rapturously realized that his cock was still hard and so I wanted to feel it inside me again.

This time I knelt in front of the bed and once again he understood.

Samson came to me and jumped on my back. Again he fucked like a maniac and tore my pussy up.

Again, during his mount, he squirted his puppy batter into my expecting twitching hole in a long series of thrusts.

Again he had me so clamped between his front paws that every drop of his juice landed in my cunt hole.

I could not hold it back any longer and while I pulled my own nipples into an extreme length with my fingers, I screamed my cumming out into the world.

After he pulled out of me and dismounted, for almost half an hour we rested lying next to each other in front of the bed.

After resting I had regained my strength again and I put my head between his back-legs.

He loved it!

No sooner had I opened my mouth than he quickly fucked his little mouth cunt.

I sucked and licked his whole fat boner and after a short time my mouth was filled with his hot cum. I swallowed, playing myself with two fingers on the clit, as much as I could.

Samson pulled his cock out of me and the next loads landed again on my face and also on my tits.

I was speechless about how much this dog could squirt?!

Samson seemed to be very pleased to call a human dog whore his own.

Out of gratitude he licked my whole body clean.

I showered thoroughly and then took him back home.

Samson is a lucky dog. Because since that day, we have had many more walks.
