Fucked by the farm dog [Fantasy Beast Story]

So summer looks like it’s in full swing here on the farm and it’s been so hot and sunny that I’ve been naked as I work for the last few days. The old man I work for likes watching me and groping me as I work and I’d be lying if I said I didn’t enjoy him looking and touching my tits and pussy. It breaks my day up and I get very wet and horny feeling his wrinkled rough old hands all over me.

Yesterday I decided to move some wrapped hay bales from the barn and into the stables because it saves me walking backwards and forwards across the yard everytime I want to fill the haynets up for the horses. The old man was enjoying watching me bend over and I could tell his eyes were fixed on my ass everytime I did. What I hadn’t realised was his big German pointer was also watching and as I bent over and pulled my ass cheeks open I suddenly felt the weight of his body leap onto my back as he began to mate with me. 

I braced myself against the heavy stacked bales and pushed my ass out further for him. The cold bales instantly made my nipples rock hard as my tits became squashed into them and sensing my willingness to be bred the big dog repositioned himself and gripped me around the waist digging his claws into my sides as he did. 
I opened my legs wide for him and instantly felt the hard wet tip of his engorged cock jabbing into my ass and my thighs. I reached back hoping to help guide his big red cock inside my wet cunt but he was so frantic with energy I could hardly move under his weight.

I heard the sound of the farmer approaching and moaned in pleasure as he held the dog and manouvered Its stiff throbbing penis into my slit.
The dog needed no more assistance and with his forelegs clamped around me began thrusting into me. I could feel his big dick being forced deep into me and I quivered as his full balls slapped against my stiff clit with every stroke. 
I could hear him panting wildly in my ear and felt his hot breath on the back of my neck as he fucked his puppies into me. 

As his cock slid in and out of my cunt I closed my eyes and felt the surge of a huge orgasm build up inside my stomach. I let out a loud moan as the intense feeling came over me and couldn’t help smiling as the hound fucked me like a breeding bitch. 
I was still enjoying my orgasm when the dog suddenly stopped and I felt my pussy being flooded with his hot semen as he suddenly froze and pumped my cunt full of his cum, his hard knot plugging my pussy opening and making sure his cum stayed inside me. 

Eventually , once he’d finished in me he pulled his thick cock out from inside me and I felt the stream of dog cum run down my thighs. I stayed there frozen with exhaustion and just enjoyed the sensation for a while before standing up. I smiled at the farmer and walked across the yard to wash myself under the cold hose dripping his dogs cum from my pussy as I did.
