A girl penetrated by a big dog cock is an excellent story.

When it’s this girl penetrated by a big dog cock, you know I’ve had a good time.

My friends were the one with the newfoundland. It started out as a fairly large puppy, but it wasn’t until I came back a year later to find out exactly how big it was. Newfoundlands, if you don’t know, are huge, with giant paws and shaggy fur. They’re also not elegant dogs; they slobber and are clumsy, and often need a lot of care.

Which is what happened when my friend asked me to dog sit for her for a week. She needed someone to watch her baby, since her Newfoundland has anxiety separation. I told her sure, I’d watch her “baby boy”, and wished her good luck on her trip.

I was not expecting the focused energy her Newfoundland had. His name was Shaggy, due to his fur, and when I let him out of his cage, he burst out and knocked me over on the floor, not realizing his strength would cause me to topple over. Newfies tend to think they are tiny dogs, and Shaggy was no exception.

When I didn’t get up from where I’d fallen face-first onto the floor, Shaggy began to sniff me to make sure I was okay- after he had some water, of course. And as he checked me out, he actually stepped on my back and made me unable to move.

He then sniffed my ass, and I cursed myself for not wearing panties that day.

Well, he decided he was very, very interested in my pussy. Licks started, long and wet, and I began to moan despite myself. I couldn’t believe this was happening- and I could barely believe it when Shaggy moved around, and something long and hard pressed against my entrance. He began to rut into me, fucking me on his doggy cock. And once he’d fucked me good and proper, he stuck his knot deep in me, spreading my pussy wide, his cock locked inside.

I guess that’s why I’m so interested in fantasy sex stories; after you’ve had a knot, you want them all!
