She quickly downed a glass of chocolate milk and began to walk toward the bathroom when she was assaulted by a sudden pain in her chest. When she look down she could see her breasts begin to visibly bulge out against her top. She fell onto the cold kitchen floor as the pain increased. Soon the pressure became too much for her top and it burst into shreds as her much larger mameries continued to swell. As they pushed out she noticed a major difference. Her breasts were now topped with four teats each. By the time the change ended her breasts had tripled their original size and had four teats at the end of each which were an inch thick and four inches long. She also noticed that whereas most cow udders she had seen in the past had been a shade of pink, her "udders" were a light brown color and her teats were a darker shade of brown.
As she sat on the floor trying to get a hold of her situation, she was suddenly hit by another wave of pain. This time it was centered around her groin. As she struggled to look around the udders on her chest she could see a mound of light brown flesh swelling beneath her flat stomach. soon this mound grew too large for her skirt and it it burst open revealing a third light brown udder. However, this one continued to grow well past the size of the others. The floor tile felt very cold against the sensitive growing flesh of her udder. When it finally stopped growing it had spread down past her knees causing her shapely legs to be splayed just slightly. At its tip were four huge dark brown teats two inches thick and six inches long.
Slowly Jen managed to get up onto her feet, the added weight of her jiggling udders making her feel much heavier than before. She leaned against the counter for support as she ran her hands over her new udders. The touch of her hands on the sensitive flesh made her quiver with... pleasure? Each stroke of her hands sent an inexplicable wave of pleasure through her body. Soon her hands made their way to her new teats and she began to send spurts of chocolate milk across the kitchen. She alternated between her three udders in a vain attempt to pleasure all three at once. As she continued to milk herself she became lost in ecstasy and didn't notice the cascade of chocolate milk she was lactating across the kitchen.
Soon the pleasure became too much for her and her knees gave out making her slump to the wet floor. As she slowly regained awareness the smell of fresh warm chocolate milk pervaded her senses. As she looked about she realized she had drenched the entire kitchen in chocolate milk, herself included. She must have dumped nearly ten gallons of her milk across the room. When she reached out toward her udder again she didn't get the pleasure she had expected. She concluded that it must only work when her udders were full because they felt empty now.
She decided to take this opportunity to go clean herself up and change from her tattered shirt. Her udder were feeling much lighter now and she caressed them idly and she made her way up to the bathroom.
