Unwanted experiment

"No my house is infested by bugs" sakura exclaimed as she had to move in with kiba. As he wasn't there akamaru was happy as sakura then was attacked from behind by an unknown individual and then had fallen unconscious. "Were am i. What is this place". Asked sakura as she then saw akamaru and a group of shinobi including tsunade staring at her from a glass door. " you were chosen to be a victim to our new project sakura, you have been to breed akamaru to create the perfect nindog". Said one of the elders of the village as she noticed she was strapped down in a lab table. "Did you think your infestation in your house was a coincidence." Said another elder. Sakura then tries to struggle out of the table as tsunade then tells her that it was the price she had to pay for her apprenticeship. Then some scientist go in the room to inject akamarus dna to sakura as she is strapped in the table. After the scientists inject it they then go out the room she is unstrapped as then white hair starts to grow on her stomach and then like wildfire spreads to her crotch as she then felt her legs thinning and a tail sprout from her back. She then suffered some pains as her bones cracked and deformed. She saw her legs more dog than human as she knew that she was turning into a dog like akamaru. She then saw her tail fully formed like akamarus as her legs soon met the same fate. She tried to stand but her pelvis started to shift and she screamed louder as this part was the most painful for now. "Stop, why are you doing this to me, why have you betrayed me." Said sakura as she then felt the final pop from her pelvis as her insides shifted. "She has survived this long she is half turned, she is ready." As she felt sick from her shifting organs the scientists then came to the room and injected something in her and the transformation stopped. " her abdomen organs are already those of a dogs, even her reproductive organs are now already those of a dogs." She doesn't have long now to get her first heat in her new mate already is crazy for her." Explained the scientists as sakura is in fear. Then the scientists put akamaru in the room and quickly went outside and akamaru smelled the entire room before sakura started oozing from her new vagina as she then tried to run but stumbled as akamaru then started to lick her vagina. She tried to fight as her new dog senses then tell her to cooperate. "Do it already". Said sakura as akamaru mounts her and starts pumping his erect organ into her vagina. She felt the pleasure for the first time in her life and it felt good. Akamaru enjoyed her body as he then started panting in excitement as sakura did the same, sakura wanted to get more pleasure as she then got closer to akamaru making him get her more pleasure as she then feels him getting faster. Akamaru exaculates and takes off his knot out of sakura as she then gets it while sustaining herself with one hand and started to masturbate his penis as akamaru groans in pleasure. Then she let him go so that he then entered her again and then she felt it good as akamaru slightly bit her in her neck to stay in one place. She yelped out of pleasure as he pounded her for a second time as she then realized what she was doing. She tried to move away from akamaru but it was too late as he had her in place with her strong body. She then had to endure the pain and wait till akamaru again exaculated and dismounted her and licked her face as he then went to sleep. "Wait till she is completely rested as the next injection might kill her if she is exausted." Said one of the scientists as they left and took akamaru as sakura then drifted into sleep. Sakura then woke up a day later as she saw kiba who then injected her as the scientists then called him out. Sakura then started to shift again as her spine cracked and she whined as her shoulder blades shifted. "Kiba wh...why." Sakura exclaimed as her breasts cracked and pushed forward and her organs again shifted and she got heart pains first as it grew three times its size giving her pains and her lungs also grew and made her breath more air as her chest grew more white fur. "Akamaru desperately needed a mate, and you signed to become her mate when you became tsunades apprentice." Kiba explained as sakura saw him with tears. Sakura felt her breasts then go into her chests and six tits grow in its place. Her arms then shifted as she then growned in pain as her hands were next. Her hair fell off as her head grew into a muzzle in a cross between a human and a dog as her ears grew like akamarus. Her hands became paws as her head completed its change as she was now completely a dog, indistinguishable from akamaru as she knew that she would soon bear akamarus offspring. Months passed as sakura adapted to her new body and finally had her pups as they grew to the point they were bought by people as she made a run for it with one of her pups and infiltrated the secret lab and found the cure as she knocked it down and both she and her pup licked it and painfully both shifted into anthropomorphic half dog/human hybrids as their paws became hands and their hips became human like. Sakura got the ability to speak again as her tits went inside her and then grew breasts as the pup did the same. The transformation stopped as they could walk bipedal again and then killed kiba out of revenge as they then gave akamaru and the pups the cure. They left the village and kidnapped some villagers and sakura learned how to create both chemicals so that one day she could create an army of dog/human hybrids and invade the humans so they can share the same gift.
