Small Town Girl and Her Dog

I live alone in a small town, about 500 people. The house I rent is small and rustic with a fenced in yard for the dogs to run around in. Callie is my 4 year old black lab and Rusty is my 2 year old stud chocolate lab. I’ve always wanted to raise puppies but they haven’t had any success since Callie snaps at Rusty when he mounts her. I’ve tried helping but Rusty gets distracted by me. One day I saw Rusty getting frustrated, so I decided to bring him in the house and into my bedroom. I got completely undressed as as soon as my panties hit the floor he put his nose to my crotch. Still standing I spread my legs and immediately he started lapping at my swollen clit. Just the thought of his doggy dick inside of me got me horny. I laid down on the bed and got on all fours. He jumped up, panting, then started to lick my ass moving up and down. Suddenly he stuck his tongue in my pussy. I gasped, feeling his long, wide tongue move in and out of my tight hole. After a few minutes of cumming on his tongue and him licking up all my juices, he mounted me. I looked back and could see his big, hard, pink dick out of the sheath and ready to fuck me. He was already dripping with clear liquid and throbbing. After a couple failed attempts of him hitting his dick against my ass cheeks I guided him to my pussy. Once he felt he was in me he thrusted so hard I felt him touch my cervix. It hurt for a little bit but when he got rhythm I was shocked with how good it felt. The hot, pink rod shoving deep inside me and his balls hitting my clit made me have an orgasm I’ve never experienced before. Then I felt his knot entering my pussy. With every thrust it went deeper into my pussy and eventually we were tied. I could feel is hot cum squirting into my uterus with every throb from his big dick. A half hour went by and his knot finally went down enough to slip away. He turned around and started licking his cum out of my swollen pussy. After letting him clean me up, I put my clothes back on and went into the backyard with Rusty. This became a weekly, sometimes daily, thing between us. Since then Rusty and Callie were finally successful at breeding and a batch of black and chocolate puppies were born.
