Someone knocks on the door

I heard the knock at the door and of course ran there to let him know this is my house.

"Fuck off!" I barked through the closed door. "I'm busy!"

That didn't seem to work though, he - I could smell it was a he! - knocked on the door again. Anna came by the door. Her body still wrapped only in the white towel. I could still smell that amazing scent on her. And from my vantage point I could admire her long beautiful legs as she stepped over me to open the door a bit.

"Hello. I think I've received your package? At least they told me to get it to you when I called customer support. Anna S. Right?" the stranger said.

"Right. I don't remember ordering anything though, but if it's in my name..." she said taking the package from him. "Thank you" she added closing the door.

Towel fell from her perfect ass as she walked back to her room with package in hand. Unpacking it - curious of what may be inside - she found the dog costume.

"Interesting. I thought about going as a nurse, but maybe I should try it on? We could go as a pair?" she said to me

"Sure!" I barked back excitedly. What could be better then going to a party as a dog and his bitch? I chuckled to myself.

"Oh wow!" She said as she managed to slid her naked body inside the tight costume and put on the mask...

Let's just say ... we didn't go to a party that night. I mounted her as soon as she dropped onto the floor. Her pink waiting vagina ready for my hard cock. I filled her before she could even bark. But it's not like she was unhappy about it.

"Fuck! Fuck! Fuck me! I'm in heeaaaat!" she barked as I knotted her.

"Yes my love!" I barked back happy as I could be.

"Fill me, fill me, yessS!" she moaned as I started pumping her womb with my sperm.

We became a happy family. Me, Grace and our new owners. Akari & Richard. They took us in after our old house got sold.

Several weeks later I became a father. Grace giving birth to a healthy lot of six puppies! I knew we'll need to give some of them away eventually, but that was life right? I was sure they were going to find a good home! For now I was delighting myself watching my beloved bitch feed my offspring, and stand guard over them!

Life was good.
