K9 officer

I'm in the military. I'm overseas. I am a K9 officer.
I have been without pussy for 3 months. I'm desperate but not desperate enough to fuck a nationalist or a street hooker.
One night while I was on patrol I heard moaning from the back of the kennel.
I secured Sadie in my car and I made my way towards the sounds. I was quiet but the moaning would have been louder than my footsteps.
I paused and peeked through the slat walls. I saw a co-worker fucking his k9. He had the dog tied to the wall and he was pounding his asshole. I stood frozen watching his cock sliding in and out of the dog's ass. The dog wasn't making any sound so I think he was used to it.
My coworker grabbed the dog's fur and began to pull him back with each thrust. He began moaning and chanting. "Fuck yeah. God damn boy you feel good... I'm gonna cum" then he slumped over the dogs back and he groaned.
A minute later he righted himself. His cock slipped out of the dog's asshole. My coworker reached and untied his collar. The dog turned around and started licking his cock.
I decided I would leave while he was distracted.
I made my way back to my patrol car. I sat in silence soaking in what I just witnessed.
It was then that I noticed my cock was semi hard.
I squeezed the head of my cock and looked at my k9 and smiled. I knew I was gonna fuck her.
At the end of my shift I went into the kennel. I locked the door. I walked Sadie to the back. I sat down on the bench while Sadie sniffed around.
I grabbed my cock and remembered what I saw and how bad I wanted to fuck a pussy and not my hand.
My cock got hard and I pulled it out from my zipper. Sadie came and started sniffing my cock and balls.
I smeared my precum on the head of my cock and offered my cock to Sadie.
Like a good girl she licked the head of my cock. Her hot, wet, rough tongue felt amazing.
I reached down Sadie's side and my fingers rubbed her underside till my fingers found her fat pussy. I slipped a finger inside her pussy. She was hot and wet. I worked my finger in and out while I kept offering her my precum.
I slipped another finger in her pussy and she started humping her hindquarters.
I pulled my fingers from her pussy she sniffed my fingers and then licked her pussy juice off my fingers.
I turned her and lined my cock against her pussy. I pressed the head of my cock into her pussy. Feeling her pussy open and allowing my cock to sink balls deep in her was intoxicating.
Said whimpered. I reached up and rubbed her ears and spoke softly to her. "Good girl. Good girl Sadie." She began to pant. I held her tail out of the way so I can see my cock thrusting in and out. I began thrusting my cock in and out faster and harder.
Sadie continued to pant as I began pounding her. Her pussy got thicker and more wet as I continued to fuck her. She whimpered once more as I shot my load. I ground into her hindquarters as my cum shot stream after stream.
I released her and she turned. Her rough tongue began to clean my cock. Each lick sent washed of pleasure on my sensitive cock head.
Once I was clean Sadie towns and started licking my creampie that was oozing from her fat wet pussy.
I smiled at the fact I found me a fuck buddy and no need to worry about pregnancy or STD.
