Encounter at the park

Part of this story is true, the rest is what I wish had happened.

I was walking my dog in a local park that I found. When I decided to sit at a picnic table. My dog was tied to the table, lying on the ground, resting, when a cute blond-haired girl with deep blue eyes wearing a cute little yellow sundress walked up asking if is could pet my dog. I said Sure she bends down, and her dress came up just enough for me to see her pink panties. Without asking, she sat next to me. She said her name was Tiffany. She told me how much she loves dogs and playing with them. She wrapped her arms around mine, and my hand rested on her smooth thigh.
I slide my hand slowly up her thighs, and when she didn't protest, I went up higher till I felt her panties. I started rubbing her pussy though her panties she just spread her leg wilder grabbing my arm tighter. She started moaning.
I pulled my hand back and picked her up and put her on the table in front of me with having to say anything she spread her legs and I pulled her panties off revealing a nice smooth slit. I lowered my head and started licking her sweet pussy. She lay down on the table and started moaning louder.
She set up and I pulled her dress off. I sucked on her nipples then I undid my pants pulling out my hard cock. I slowly push it into her pussy starting nice and slow the harder and faster I start pounding her pussy with everything I had till I came hard and deep inside her. At some point, she must have passed out, so I took my dog, put him on the table, and watched as he licked her clean. She woke up and started moaning some more. I started to get hard again so I had her flip over so I can see her sweet ass. I pushed her cock in her harder this time fucking her ass with everything I had and left her there completely nude with my cum linking out of her.

The truth part is up to the point where my hand was on her thigh. A couple was walking their dog close by and she got up and ran off. I went to that park for a couple of weeks looking for her, but never saw her again.
