She started with her udder. She moved it around and felt a faint sloshing of milk. She felt the same in her breasts. She then started her way towards camp.
She grabbed some sleeping powder from the cart and grew some over Jennifer. "Soon you will be like me." At this point Kim had given in and started to accept being a cow person.
She picked up Jennifer and brought her to a nearby hill. Kim then stripped Jennifers clothes off. "You won't be needing these." Kim said slyly.
Kim then moved her udder to feel how much milk was in it. "Just enough." She exclaimed. Kim then opened Jennifers mouth and put one of the udders teats in her mouth.
At first the milk just went in Jennifers mouth but after 30 seconds she started to subconsciously suck on Kim's teat. "Yes. Good. Moaan." Moaned Kim. "Mooann. Moooannn. Moooooo."
Jennifer then started to change. First she grew a tail. The her feet formed into hooves. An udder started to grow and her vagina moved towards her butt.
