Anther dog gets fucked

I allowed Bella to lick my cock and balls cleaned, while I catch my breath.
Once she started licking my cum out of wet fur I sat up. I tiptoe to the door. I listened and heard the dogs barking from their kennels.
I slowly opened the door and crept down the hallway.
I saw the light on in the room where Russ was in. The door was open. I got to the doorway and listened. I heard movement but I couldn't distinguish anything though.
I stood still and listened. I heard a dog whimper. Russ said "yeah I'm gonna fuck you Daisy girl. "
Daisy was the Great Dane we were boarding.
I heard heavy breathing. I peaked my head around the doorframe.
I saw Russ sitting on the chair with Daisy's hindquarters between his legs. He was moving the dog back and forth. Daisy whimpered but Russ wasn't stopping.
Russ continued to fuck Daisy he was in a steady rhythm not fucking her hard but his cock was so big I knew he was deep.
I felt my cock getting hard again.
I slowly started stroking my cock while watching Russ fuck this Great Dane dog.
Russ had his eyes closed and was biting his lower lip. His steady pace was exciting me. His control, his taboo kink, his passion watching him fuck this dog.
I was stroking my cock to the rhythm of Russ. I was surprised at how turned on I was. I was lost in thought when I heard Bella start barking.
I opened my eyes and saw Russ smiling. I froze with my hand on my cock.
Russ spoke calm "come on over. This bitch can handle two cocks." I was still frozen.
Russ started thrusting harder. Daisy whimpered. "Come on or I'm going to have to fill both her holes by myself." He whispered.
I was shocked that I was walking towards him. I had my cock in my hand.
Russ manhandled Daisy and flipped her around till her belly was on his belly. Her legs were straddling Russ.
He reached down and grabbed her tail and pulled it up. I saw his massive cock stretching her pussy. Her pussy juice had coated his shaft, his balls, her fur. Her asshole was buldging with every thrust.
My cock was the largest it had ever been. Only 7 inches. I was still no comparison to Russ's massive cock. His cock was easily 9 inches long and Coke bottle thick.
As Russ held her tail up I stepped closer and rubbed my cock head against her asshole smearing her pussy juice as lube.
I pushed my cock in. She was tight. I started thrusting slow alternating with Russ. I felt Russ's cock going deep in her pussy and I was giving her ass a good fuck.
Daisy was panting and whiny as we were fucking her good.
Russ locked his legs around me as I stood beside the bed. His touch was arousing me even more.
I never thought about another man's touch but I was getting more and more turned on.
Russ grunted and moaned "fuck dude I'm gonna blow in this bitch" I felt his cock twitching in her pussy.
I could smell his cum leaking out her pussy. I kept fucking her asshole. His cock slipped out of her but he held her and he kept me locked with his legs.
I moaned "I'm coming". I thrusted once more and ground my cock balls deep. My cock shot cum deep in her asshole.
Once I finished thriving and my soft cock slid out of her ass Russ released my legs. I stepped back giving Daisy room to get down and start cleaning our cum off her fur.
Russ smiled and said "I think we have a good thing here my new friend".
