You smile slightly as you nod to the dog. Some how you knew he was right. As odd as it seemed you couldn't shake the urge to be his bitch, it just felt so right.
Duke walks up to you and gives your cunt a long wet lick, which sends a shiver of pleasure throughout your body. "Now get on your hands and knees bitch. I only turned you back so I could fuck you as a human."
You take a deep breath as you slide down onto your hands and knees, lifting your ass to the dog. He quickly moves behind you and lifts his paws on your back. You can feel that hard cock quickly growing as it rubs against your rear before finding its way into your hot cunt.
You gasp softly as you feel that dog cock sliding into your dripping sex. You can feel the heat of it filling your body. Your eyes slowly close as you moan. "Ohh yes Duke I love it!" His thrust pick up quickly as he works that hard shaft in and out, his knot quickly expanding. The walls of your sex stretch to take that huge knot which pulses with heat.
Your scream out in pleasure as you feel that huge dog cock begin to fill you with hot steaming cum. Your body shakes wildly as your cunt grips about it tightly, untill finally you collapse onto the floor, panting heavily.
