Hiking in the forest went wrong

So this happened last week when we were camping with my friend. We went on a hiking trip in the forest, it was kinda far away from civilization so I was kinda anxious for wild animals. When we got there my friend realized he forgot the thing where we kept our food so he said he would go get it and told me to stay here to set up our tends and maybe get some fire wood. I was so horny the whole drive so I thought i’ll set my tent and masturbate while my friend is gone for a while.

I tried new position I saw from a website while rubbing my clit, I think it was called “Butt doggy” where you stand on all fours fingering. I lowered my panty, while exposing my butt outside. I got excited by the though that someone could see me. Then i heard some noises from outside but thought nothing of it as it was pretty windy. Then it happened I felt something behind me, exactly when i looked back he mounted me. He was heavy and kept me still, then i realized I was butt naked with a dog behind me that didn’t let me move. I felt something poking on my butt and i didn’t like it. I couldn’t believe it,  he was brushing his penis against my butthole .I had to do something before it was too late. This dog had his bare dick between my asscheeks.
