Katie wakes up in the middle of the night laying on her side. They were no longer tied and John's cum pooled on the bed beneath her. They hadn't moved though so his doggie dick was still inside of her. Remembering what happened earlier she got excited again.
Reaching behind her she rubs John until he is awake.
"Come on Johny lets go again, boy."
John agreed by starting to stiffening again.
Katie didn't even get off of her side John just started humping into her again she came twice before he knotted her again.
The same thing happened two more times that night. Each time she imagined her self as a dog being bred as she came. Each time it felt better to her she came easily and more often and harder.
She was awakened in the morning by John bumping his knot into her pussy lips. He was humping her again. she automatically started pushing back to meet his thrusts. She fantasized again, that she was a bich being bred. As the knot popped in it felt very different. So much more filling and she could feel the pointy tip of his doggy cock pressing against the entrance to her womb. as the knot continued to expand the tip of his dick pressed harder and harder into her. it was kind of painful but when she realized each spurt of cum would shoot straight into her uterus. it pushed her over the edge into a hard orgasm. Each spasm of her pussy milking more puppy batter into her waiting womb.
John had a doggy smile when he realized he was bottoming out. He really wanted to breed his bitch. and he felt like this would do it. what kind of a thought was that? Are instincts taking over?
Katie ran her hand over her stomach thinking of it filling up with cum. She felt several odd sensitive bumps
Looking down at her body she realized she had six extra nipples on her belly. A sound escaped her lips that sounded a lot like a dog's whine. John was changing her!
The whining sound got Jons attention. He sat up as much as he could with them still firmly tied. He was shocked and then a little proud to see the extra nipples in two rows down her belly. She really is becoming my bitch he thought as he continued to fill her with his seed.
It was forty sperm pumping minutes before John could pull out of her. as he popped free, instead of the usual gush of cum almost none came out. Katie's womb felt bloated. reaching down to her pussy she realized immediately it felt weird. She grabbed a mirror from her bed side table and held it where she could get a better view of her crotch. everything back there looked like it belonged on a dog. she had a dog's pussy lips a dog butthole and even a little tail. There was cum matted fur growing in on her butt cheeks too.
"Oh no! We have to get back to the store!" Katie said
Getting dressed Katie realized pants wouldn't work with a tail so she opted for a skirt.
The whole time John was smelling her pheromones. She smelled great before but now he was already getting hard again.
she grabbed his collar and headed for the door.
Her skirt was kind of short and from Jons perspective, she was flashing her panties at him with each step. it didn't help that each movement of her skirt wafted more of her scent at his sensitive nose.
In her excitement yesterday she had dropped her keys on the ground. When she bent down to pick them up John couldn't help himself he gave her crotch a great big lick. It was sensory heaven. his nose was full of her scent. he could taste a little of his cum from earlier in the morning as well as her juices.
Katie froze. She had to get up and get them both back to the store and sort this all out. She also needed to get down and breed with her mate.
