My loving dog

When I was younger we had an Australian cattle dog named jack. He usually slept in my room and I was extremely horny so one day I call him too me and slide my pjs and underwear off and spread my legs open for him, it only took a few seconds before he started licking my pussy.
He wasn’t that good at it but it felt so good I kept cumming, his teeth kept scraping the inside of my pussy, ripping it in some places, which only made me cum harder. He kept going and going until I could only lay there shaking as he kept licking. What seemed like hours later he finally stopped and backed off, I laid there, legs shaking, pussy hurting, and exhausted. I soon fell asleep. In the morning when I went to the bathroom it burned and hurt to pee but this made me realize how much of a masochistic dog slut I was. Every chance I was home alone I spread my legs for him (which was almost every day) the pain of the day before remained but I loved it so much I couldn’t stop. I started reading beastiality stories online and BDSM ones and I wanted him to fuck me so badly but I could never get him to, even tho he was unneutered. I was so disappointed, but there was something else I could try. One day my dad was home and I said I was going to take a shower and take jack with me, we often had the dogs in the bathroom with us as we showered since they were clingy, I turned on the shower and pulled off my belt as I stripped and pulled it around my neck so I couldn’t breath, I then grabbed the clothespins I had and played with my nipples until they were hard and put them on, it stung but it felt so good. When I was finally ready I laid down and opened my legs, I was already so wet from the anticipation he immediately went to town, within seconds I was cumming and seeing stars like never before, I set a timer for 10 minutes so I knew when to stop and shower before things got suspicious. Over and over he made me cum and I started cumming so hard I almost passed out from the lack of air, I gasped as he licked the deepest parts of me and pulled for air, when the timer went off, what seemed to be too soon I pulled off the belt and sat there shaking and gasping. I got up and showered and came down like nothing happen, when my father asked why I was limping I told him I cut my leg while shaving, which he seemed to believe but I had to hide the fact my pussy was still dripping wet. When the marks from the belt finally formed I said that I woke up with my blanket around my neck again, which was also believe able. I’m so sad I was never able to get fucked by Jack or take his knot, sometimes I hoped my dad would walk in on us and take me himself but that’s a fantasy I can share another day
