We loved our job

The next day when my alarm went off. Bella jumped up and immediately started backing her hindquarters against my morning wood.
I slipped my fingers under her tail. Her pussy was fat and welcoming.
I pushed two fingers inside her hot, wet fur till her pussy opened up and accepted my fingers.
Bella began to hump my fingers.
I pushed the blanket off and turned on my side. I lined the head of my cock with her pussy. I pulled my fingers out of her and she started cleaning her daddy's fingers. I thrust my hips pushing my cock in her. The heat, the wetness the folds were amazing. I thrust in and out thinking about the night before. Remembering Russ and Daisy the Great Dane. How Russ and I DP'd her.
I found myself balls deep in Bella. I moaned loudly enjoying my bitch, my morning fuck before the vet opened.
I heard a soft knock on my door.
I opened my eyes and saw Russ. He was naked and his massive cock was standing proud.
I nodded yes. He walked in and closed the door behind him.
He whispers " just let me watch man, I won't join unless you want me to".
I nodded again.
I felt the mattress shift as he sat. He started rubbing Bella's ears as I continued fucking her pussy.
I closed my eyes as I thought I was fucking a dog with a man watching. I would never imagined this years ago. But look at me now.
I felt Bella jerk. I opened my eyes to see Russ letting Bella lick the precum off the head of his cock.
I moaned and started giving her deeper thrust. Bella whimpered.
I felt Russ moved on the bed. His hand was rubbing Bella's belly. Inching closer to my balls and cock.
I kept my eyes closed. I kept thrusting.
I felt his fingers brush against my balls. I could feel his fingers rubbing Bella's wet fur. I felt the need shaking. I heard Russ breathing hard. I knew he was jerking off watching me fuck Bella.
I thrusted deeper. I pushed my cock deep feeling her fur on my balls.
I grunted as I pumped my bitch full of my cum. With each throb of my cock more cum filled her pussy.
I heard Russ groan "Hot damn bro you fuck this bitch good. I may need you to fuck me soon".
I smiled and told him maybe. As Bella began to lick her pussy juice of her daddy's cock.
