Hi, Im 18 and my name is brittany, I stole my grandpas vodka and got really drunk while they were gone. I was horny and seen their black lab jack in the basement… I had the bright idea that maybe he would fuck me… well bad idea! He did fuck me but not like i wanted! After i jerked him off a few times after i pulled my pants down, he was humping the air the whole time hard. soon as i dropped to my knees he was on my back, but before i could do anything he hit my butthole! soon as he did he hammered it harder and fast! I screamed cause it hurt so bad! A dog has whats called a knot i didnt know about and it was stuck in me i was in so much pain and couldnt get his dick out of my butt forever he finnaly pulled and it popped out, and i guess he came in me too I didnt know what to do when i looked in the mirror is when i seen i had clear liquid comeing out of my butt and it was really red, and i could see the pink inside cause it was open. thats the hardest and most painful sex ive ever had, and the only time i ever had anything up my butt..
