K9 officer goes undercover (part 1)

Back in the states I find employment quick as a K9 officer.
I was asked to transfer to go undercover. Of course I accepted.
Once I was set up with my new identity and apartment.
I set out to follow my orders. One night I took Sadie for an evening run and I saw some movement down a darkened alley.
I looped around and peeked through a vine covered fence. I saw a lady getting fucked by 2 men. One was pounding her pussy and the other was face fucking her. I stayed still and quiet as I continued to watch this lady get fucked. My cock got hard and I needed to release this tense and I wasn't in the mood to run any more.
I quietly stepped back and adjusted my hard on. Got Sadie's leash and started walking back to the apartment. Sadie kept trying to sniff the precum stain on my shorts.
I assured Sadie "you'll get fucked girl as soon as Daddy gets you home".
Once inside the elevator I rubbed Sadie's ears as her snout was sniffing my crotch. I pulled my cock from my elastic waistband. Sadie began to lick the precum off the head of my cock.
"Mmmmmmm" I moaned as Sadie's rough, hot, wet tongue licked my cock then her tongue wrapped around the shaft.
The elevator ding caused me to open my eyes and shove my cock back in my shorts. The doors opened and a middle-aged lady got in. We smiled in recognizing each other.
Sadie whinned and moved her snout back to my groin.
I pushed her snout away as my face burned with embarrassment and frustration.
"They always seem to want what they can't have" the lady spoke as her gaze was on my still hard cock tenting my shorts.
I chuckled and replied "yeah, that she does".
The elevator dinged again and it was my floor. I nodded and wished her a good night.
Once in my apartment I locked the door as Sadie panted and backed her hindquarters against my leg.
I pushed my shorts off and Sadie began to sniff and lick my cock again. I grabbed my cock and pulled it up giving Sadie access to my sweaty balls.
Feeling her rough wet tongue lapping at my balls while I stroked my cock felt so good. I moaned as I landed against the now locked door.
I pushed Sadie away as I walked to the bedroom. I pulled my shirt off and stood next to the bed naked. Sadie jumped on the bed and began to pant and back her hindquarters against me.
I moved my fingers to her wet fur between her legs. Her pussy was swollen, wet and hot. I pushed to fingers into her. While I stroked my cock with my other hand.
Sadie panting got louder as I moved my fingers deeper and faster.
I bunched my fingers as I shoved them in her but I spread my fingers as I pulled them out. Over and over stretching her fat, wet, black swollen pussy.
I didn't want to wait any longer as I pulled Sadie closer and pulled my fingers out. I smeared her pussy juice on my cock making it shiny and hard.
I moved the tip of my cock against her pussy. As I pushed the head of my cock into her she whined.
I grabbed her back legs and pulled her backwards as my hips thrusted forward.
Feeling her hot wet pussy hugging my cock felt so good. She was panting as I was thrusting in and out. I moved her tail out of the way as I watched her asshole wink with every thrust.
This made my cock grow even thicker. I began to pound her. I grabbed her and pulled her back hard feeling my balls smash against her.
I grunted and arched my back feeling my cum shoot inside her. I groaned as I leaned forward onto the bed. My cock slipped out of Sadie's pussy.
Sadie turned and started licking my cock. My cock throbbed with each lick. I caught my breath as Sadie turned and began licking my creampie from her wet hair and fat pussy.
I went and showered while I washed my mind went back to the lady getting fucked rough by those 2 guys. I decided then that I needed to get me a male dog too. I want to fuck her while my dog fucks her DP style.
I wrapped a towel around me and headed to the computer and I typed "German Sheppard dogs for sale" I smiled when I saw several listings.
I confirmed a meeting to see the dogs the next day.
As Sadie curled around my feet I smiled and flipped the TV on.
