Katy was used to being fucked like a dog. However the sensation was different this time, it wasn't like with the dildo or Buster or Cal. It was like she was trapped in a Halloween. She felt her naked body being pushed into that of her dog form. Her breasts were mashed against her chest, her head felt like it jammed into a vice and her limbs stuffed into clothes painfully tight, she felt like 50 pounds put into a 15 pound bag.
Lucas the rottweiler wasn't having much more fun, she could sense through some form of pheromone or mental link that the man she had bit was slipping into his new form any easier. However he was adapting, Katy was used to feeling like a dog that the change was seductive, like a drug or addiction, but her new form was torture.
Lucas had never experienced anything like this before so he was running not on thoughts but on mental processes. His hard on was pounding through his canine mind and the bitch he could smell. While Katy tried to make new form work like prior changes she had collapsed on her front paws, presenting her rear for Lucas. She felt Lucas land on her and after some fumbling entered her.
"AAAHHH!" Katy screamed.
Her canine howl had a similar note to it but then the fog of which species she was lifted. She felt as if she were naked standing with her long red hair half blinding her as Lucas started to get a rhythm going, pumping into her. She now felt like a college cheerleader with a quarter-back having a quickie in the locker room after a game or a few drinks.
Lucas' hands/paws rubbed her nipples and she felt as if her B cup breasts were being fondled. She sucked in her stomach and felt his hand run down her ribs, which could be seen in the mirror, to her vagina. But gripping her hips he fucked her like a woman. A third person would have only have seen two dogs. As he climaxed Lucas grunted like a man.
It wasn't rush of sperm but an arrow, straight from his canine dick into her canine womb. However Katy felt it as a woman, the sperm shooting into her. She moaned "Oh God." clearly but it came out as "Mrwrrrgrrrgll". Katy tried to get away from Lucas but he was more dog like, by nature he knew to hold her for twenty minutes to make sure he had planted the seed.
He finally fell of her and went to sleep. Soon however, she began to get a scared look in her eyes, and she whimpered softly as they changed from yellow to her natural green. The white and brown hues in her fur started to change to a consistent red and her nipples disappeared from her now hairless torso and a perfect round youthful set of human breasts sprouted from her flattening chest. Her dog body elongated, the hair on her back and legs receding to reveal creamy pink flesh as if she were going bald. But those lost patches of hair vanished.
The hair on her head, on the other hand, sprouted out thicker and longer. Her face too became suddenly human. The tail withdrew into her back and her ass, more shapely as a husky, started to bulge out into her female form.
She was a gorgeous redheaded woman of about 20 years. Her flowing red hair covered most her upper body, but her naked body was clearly well formed and athletic. She looked up at Lucas and whimpered like a dog. She found a shirt or rag and wiped her vagina. A feeling of dirt or poison entered her mind as she shivered from the cold. Her body was leaner and she had been eating less given her transformations. Her mother had asked her if she were anorexic even though 21.
She cupped her breasts and knew that she had been enjoying a magic that allowed her primary, inhuman pleasures but now she had to paid the bill...
