Dogs know best

Was horny as hell.so skipped school played i was sick so got to stay home who needs to go to school 9th graders know every thing already anyway. so put on my sister's bra and panties cute little short mini skirt cute little top and some of my other sister's sandals. Snuck down stairs no one home so outside I go. live beside a busy highway early 1981 so got to judge the traffic just right to sneak out to the Grove to walk around without getting scene. Our dog blu a big german shepherd is by my side down to the creek started playing fetch then the ball gets caught in a small tree by the water trying to reach it and yep in I go blu thinking we are playing i try crawling out of the water and he jumps on me and starts humping me i try getting away but he wraps his front legs around me and keeps humping i can feel him trying his best to get it inside of me but figured my panties would keep that from happening must of been a tear or hole in just the right spot and before I could do anything it was inside me and being a complete virgin back there at the time it felt huge the more I tryed getting away the more he growled so I was in for the ride of my young virgin life he grew bigger and bigger i was crying to let me go but he turned and then we was locked together I stayed there and cryed for a long time before he popped out and like a gusher I felt his come running out of me all the way back up to the house it was leaking out and I was bloody beside made it back to the house and soaked in a hot bath for awhile later on my mom asked me why I was walking so funny told her my butt hurt without thinking and she kept asking me why!!! Didn't think she really wanted to know the truth but also made the comment that the dog seemed really happy!!
