How I became a total slut

I got really horny and I dressed in a skirt with a thong that barely covers my asshole. I stuffed my ass with a butt plug and went in the park to flash my bare butt to strangers.
There was a man with a dog walking, so I bent over in front of him, completely exposing my ass.
We began making out and he tied me up with the dog’s leash. – I thought to myself
“What can go wrong” then I turned my head in shock and saw his cock swinging in front of my eyes.
What came out of my mouth was – “W-wait, I only wanted to tease guys with my butt, I never intended to get fucked”. Then he said his dog is gonna have sex with me. “Is he joking? I don’t wanna get fucked” by a dog!!” Before i knew it that nasty creature was already on top of me rubbing his hard cock between my asscheeks, using my assmeat to get off. It almost felt like he was fucking me through me thong. 
The man asked “Which hole do you choose? ”
My hands and feet tied, so had I no choise, but to say “my ass”.
He was about to put the dog’s cock at my vagina entrance. Did you lie to me? It was too late, the animal began pounding my pussy, the man’s cock somehow got in my mouth and I was now getting fucked from both sides. Out of nowhere his dog switched holes, shoving his entire dick in my ass.
I had two fat cocks thrusting in my throat and asshole. I couldn’t help but feel the tiniest bit of pleasure making its way inside me.Then he stopped all of the sudden and with what will forever be a stab in my pride and self-esteem I, not even realizing it almost as my body had taken over my mind, pushed my ass towards his cock, leaving my ass completely exposed. The dog took advantage and shoved his huge knot in my ass, painfully stretching my hole which made me cum hard.
I felt like a cheap slut to let a dog cum in my ass. The man ejaculated filling my mouth and untied me. I was so horny I begged him to fuck me in my asshole.
My ass was dripping full of cum when I got home.
