I dropped to my hands and knees in front of him, and openly presented my dripping pussy, begging him to mount me. I stood him up, and marvelled at his size, much bigger than i thought a dog of that size could be. Before taking him inside, I lowered my pussy against his knot, my petals sliding around it, his hard cock spurting little jets of cum onto his belly. I had discovered how big my dog could be, how good he tasted, how kinky I could be, and how if it looked big outside, it felt immense inside my tight ass! My parents both worked, so I spent most days at home looking after our dog a handsome black lab. For certain I know no human lover has been quite so sensitive after a fuck, nor been so hugely satisfying! I ripped off my clothes and wrapped my body around him, my nakedness enjoying the feel of his fur. I had to fuck him. We did pleasure each other orally a few times, but I was very self conscious any time he would sniff my crotch that people would guess, and I never had the courage to mount him again. This Animal sex story was exclusively written for http: I really loved this dog, and so no point in stopping having come this far. Suddenly, I had doubts. Suddenly I was screaming and wailing with a pleasures so intense it was almost pain as a massive orgasm crashed through my young body, my tight anus milking his cock as my pussy spasmed, my rock hard nipples and firm tits bouncing furiously as my whole body shook with my incredible climax. To my inexperienced eyes he looked magnificent. To my frustration, his inexperience meant he had no idea what to do. He rolled over, and licked his belly fur and cock clean, then came over and gently nuzzled me, before snuggling beside my naked body on the floor. I was still stroking and massaging his balls and shaft, admiring his wonderful penis when without any conscious thought my eyes closed, I lowered my head and took him in my mouth.
