On the way to school, all Jen could focus on was how hungry she was. She hadn't had time to grab anything to eat due to being late. Oh well, she figured the vending machines would do.
When the bus pulled up, Jen stepped out. Out of the corner of her eye, she noticed a strange wooden barn-like building next to the high school. Was that there before? She wasn't sure, but she was certainly tempted to check it out. Walking over, the door creaked as she peaked inside. Machinery lined the walls, which were surprisingly made of steel as was the floor, and even the ceiling which stretched pretty high. At the far end of it was a large and wide stall with a large jar of blue cookies sitting on it. Her stomach grumbled, as if compelling her to eat it. Jen attempted to resist, but soon gave in and rushed for the jar. She sat down, yanked open the lid, and stuffed one in her mouth. The second it hit her taste buds, all other thoughts went out the window. All she could think about were the blue cookies, which she was now shoveling into her mouth like a machine. She was so focused that she didn't even notice the changes that were taking place.
Her skin was turning a vibrant blue color and her clothes were beginning to stretch until they ripped off completely. Her skin stretched as she obtained more fat, growing at a rapid rate. As her abdomen expanded, a lump began to form on top of it followed by 4 more that began to grow into teats about the width of an average apple and the height of an average watermelon. Her but was also inflating until each cheek was the size of extra-large beach balls. Her breasts also inflated to roughly the same size, but Jen didn't even notice. She only had one thought on her mind; eat. And with the cookies regenerating in the jar, her thoughts would stay.
After about ten minutes of eating, Jen's head hit the ceiling. The moment it did, her mind shut off for a hot second and she dropped her head as her brain reformed. It was slowly being replaced with a computer. At the same time, various tubes were appearing. One went up her urethra and another into her asshole, along with strange devices that looked almost like it was for milking cows. The devices attached themselves to her udder, breasts, and pussy, locking onto them. At the same time, Jen was being restrained by stretchy metal straps for when she grew even more.
After a while, Jen's brain began to reboot and her head slowly rose up.
"Powering on," she said in a robotic voice, her face void of any emotion. "Interface on, connected, releasing pheromones, beginning juice and berry production....."
As the machines sprung to life, Jen felt wave after wave of pleasure. After a while, she heard the door open and in walked....
