I love my mastiff, George. I've had him since he was a puppy, and now that he's a year old we're very close. We're so close, in fact, that we're never apart. I listen to everything he tells me and I can't even remember the last time I left the house or got dressed. He likes me to crawl around on the floor with my ass in the air because he likes me to offer myself up to him at all times. He also likes it when I call him Master. I belong to my Master now.
As soon as I got off the couch, George jumped up and stood over me, the clinking of the metal tag on his black leather collar ringing in my ears and making me even more desperate to submit to him. I could feel him behind me as I reached my hands back to grab my ass cheeks. My head was down on the ground and my ass was high in the air, and I spread my ass cheeks wide for him.
George inspected my pussy and asshole with his nose and tongue, then put his front paws up on my ass. I could feel the enormous head of his cock rubbing up and down along the folds of my pussy, and when it found the hole it was looking for, my pussy hole, I felt it start to enter.
Because of his size, it took George a little while to get himself inside me. I felt like my pussy was stretched as far as it could go, but still he wasn’t all the way inside me. He was starting to thrust harder and faster in his frustration and when he finally pushed through I screamed. His massive cock pounded into my pussy like a jack hammer.
I’d never felt anything like it before in my life. The long, thick dog cock was deep inside me, filling me up and stretching me beyond my limits. But again, his cock seemed to be getting even bigger. I suddenly remembered hearing that the male dog knotted up inside of the bitch it was fucking until the male came, ensuring that the sperm would stay inside the female.
That’s exactly what was happening. George’s cock was so big now that it felt like I was being fucked with a baseball bat. He was thrusting that massive cock into me like crazy and it felt like I was being split in half.
