You feel weirdly juicy in your loins and can smell that you're in heat. As Duke approaches, his male scent is overwhelming. Your jaw hangs open and you salivate. No, you have to stop this.
"Down, Duke! Down Boy!" you command backing away from him. Suddenly, you find yourself backed into a corner--literally--you plead, "No, Duke, I'm your master!"
"No, bitch, I'm your master, now turn and present yourself for mounting," he barks his orders at you.
You turn slowly unable to resist.
"There's a good bitch, now call me "Master Duke," the dog orders.
You try to resist but you can feel the heat of his body rising on top of you. His furry belly rides up on your back as his conical organ penetrates and starts to swell within you. You're panting like a dog, and trying not to enjoy your new role, but nature beats enviroment. You may have been raised a man, but you're now a bitch with all her instincts.
Duke pumps, and pumps it must be 10-20 minutes. A terrible thought hits you and you mutter aloud, "I can't get pregnant, can I?"
"Sure can bitch, that's the plan. If you're pregnant, you can't change back until the pups are weaned, but I can use the collar on others. Your buddy Mitch, and I are going to be real good friends," Duke laughs. Dogs don't laugh do they? He's a lot less furry too. His cock seems to be changing inside you, but you figure it's just the knot releasing. Then you notice Duke's big paws are reshaping themselves. Duke's paws are now hands, big male hands, and yours are still paws.
Duke reaches around and unbuckles your collar.
"Yep, you're going to have a litter, bitch!" he laughs. "Or I'd be changing back into a dog and you'd be turning back into a man, and that's not happening."
You whine unable to speak intelligibly to your human master Duke.
"Now as for Mitch, he's not going to be a bitch dog, but he's still going to be my bitch, and your stud!" Duke says waving the collar around.
Great Dane? You think, well the human Duke does look sort of nordic. Big and chiseled male features, but you miss his canine form. You sniff his crotch as his dog scent fades and a human scent grows stronger.
As I recall, Mitch is coming over for the game tonight. I'll explain that I'm your cousin, and brought my bitch-you-to breed with Duke. You were called away and took Duke with you. Oh, and I'll explain that you named your dog Duke as a joke because that was my name. I'm sure we'll get a good laugh. You're so dense, I don't think you ever caught on that Mitch is gay. He's sports a boner for you every time he comes over, so I'm sure I can coax him into bed. He'll make a good stud for you, and as long as you remain a pregnant bitch, I remain human."
Duke is rummaging through your drawers and trying on clothes, he finally settles on some xxl sport shorts and a basketball jersey you won at a charity event. He goes to the kitchen and struggles with the can opener until he finally manages to open a can of dog food.
"Here, bitch! C'mon get it, you're eating for 2 or maybe 10 now!" he barks a laugh.
You drag yourself in with your tail between your legs.
Duke helps himself to a beer, and plops his ass down in your recliner in front of the tv.
"Man, I never knew colors before. Didn't know what I was missing," he comments as he watches the pregame tail gate party cam filming the college boys and girls putting on their best MTV party moves for the camera.
You suddenly realize that your world has literally gone monochrome. The cacophony of smells you've been noticing have supplanted color images in your brain. A fair trade you think, recalling how you turned up your human nose at the dog chow, but now it smells heavenly as you devour it.
"Yeah, my litter mate, really tricked you with that collar. I wonder if she's change any of my siblings human too? Too late to visit the mall now, Mitch should be here any minute. Maybe tomorrow?"
The doorbell rings...
