A scent hit your nose, you smelled around, it was like nothing you had ever smelled before as a human, it smelled so, good. Before you could investigate your pet German Shepard Molly comes in and sees you, barking in surprise before smelling you, she must recognize your scent somehow as she barked happily.
Well, you're a dog you might as well enjoy it, you circled around her, sniffing her backside. That's when the scent hit my nose again, it was coming from her, she was in heat.
You could feel my doggy cock coming out of its sheath, my new instincts where going wild. Where you really going to mount her, or should you resist?
you couldn't help yourself, your human mind was screaming at you to resist, but your dog mind didn't care. You came up behind her and mounted her, thrusting into her. She let out a yelp, and you paused just a moment, where you really going to do this?
You couldn't help it anymore, you thrusted into her all the way, my knot locking us together. The more you thrusted, the better it felt, your human mind's protests where slipping away with each thrust, replaced by the pure pleasure of mounting this bitch.
You both howled together as you shoot your seed into her, your thrusts slowing down as we waited for my knot to deflate. You couldn't believe that you had just done that, you had acted like an animal.
When you could finally slide out and dismount her, you no longer cared. Maybe if you where going to be a dog for a day, you should at least embrace it.
