It was mid saturday night, 3:30 in the middle of the night two and a half hours before Jen had to officially wake up. Jen couldnt sleep, her body felt uncomfortable, so Jen got up wearing her night button shirt and pajama pants. "Ugh....my body feels weird...." said Jen in an exhausted and annoyed voice, she was sitting in her bedroom, on her bed. Jen felt some sort of tingling coming from all over her body, but there where some that came from particular areas. As she sat there trying to find the areas, and increase in tingling came from her breasts. Jennifer looked down and saw her shirt stretch slightly, her nipples began to give even more of a strange tingle, as if they where more sensitive they also seem to begin to press against her shirt. The buttons began to let lose of her shirt one by one as the tingling increase along with some sort of pressure. Wet spots formed around the area where her nipples are pressed against her shirt, her nipples seem to be stretching slightly as well. Jennifer was scared seeing all this, but most of all confused very confused. After 20 minutes, all the buttons in her shirt where her clevage is located where gone and part of her breasts where showing along with part of her areolas, her breasts had grown from mid c cups to high D cups. There was milk dripping along her breasts, and her nipples felt very sensitive. Jennifer slowly took of her shirt in order to see better what had happened, and went to sit by the window where the moonlight would help see better. Just as she did this she felt a tingling down the base of her spine. She felt her spine elongate and some thing like hair brush against her pajamas, after 5 minutes she felt some long rope like thing brush against her butt cheeks and even brush against her womanhood. This made Jennifer jump, as it also aroused her slightly, making milk drip out of her nipples a bit faster. The twitching and moving tail in her pants was making Jennifer get more and more aroused as it brushed against her womanhood. Just as Jennifer decided to take her pants and panties off, a new tingling sensation came off from above her vagina and lower abdomen. Jennifer quickly finished taking her pants and panties off freeing the tail in order to make room for the new change. Her abdomen started bulging and turning pink, it started feeling sensitive like her new pair of breasts, and as it bulged and got filled with the same milk in her breast, nipples came out, they then stretched and became two pair of teats, 2 inches long, once it got finished forming, milk started leaking from all four, and the udder felt extremely full, just like her breast felt at that moment. After this strange events Jennifer realized she was turning part cow, she looked down and stared at her milk filled breasts and udder, she always wanted to know how it felt like to be milked like a cow, and she was painfully filled with milk. Jennifer then walked over to her bathroom, and entered the bathtub. She knelled down, with her tail swishing too and fro, looked down at her breasts and udder, as they wept milk from the teats and nipples. With one shaky hand she grabbed her left nipple, and with the other she grabber her right upper teat, good thing she had been milking cows for a very long time by hand, she thought just as he began squeezing and pulling on both the nipple and teat. The feeling was amazing, she thought as her new tail swished too and from happily, the overly sensitive nipples and teats, the sensation of the warm milk coming out of them, the sore yet sensitive feeling of the breast and udder as they jiggled from being pulled and squeezed. It was amazing, Jennifer enjoyed pulling on her nipple and teats, she enjoyed massaging them, rolling them and puling them as hard as she could for the warm milk. At one point she let out a low muffled moo, trying not to wake up her family, milk sprayed thickly out of all her teats and nipples from the sexual excitement. As she saw the milk spew out, she got curious as to how it tasted, so Jennifer grabbed her right breast and plugged it in her mouth, the milk was so creamy so smooth and sweet tasting, much better than any of her cows had ever given her. As Jennifer milked herself, with the pleasurable feeling no amount of masturbation ever gave her, she failed to notice new tingling sensations coming from her body, and new changes, changes that started occurring from...
