Jeff waited for what felt like hours, and she was bored as hell. Drawing lines in the dirt she sat there and wait for daylight to break. Her stomach felt taut but she paid no heed from her game of drawing before a slight rumble drew her attention.
Looking down at her stomach she was surprised to see pink skin barely standing out between the rest of her tan skin, four small bumps on the patch of pink that just looking at made her feel giddy. Pressing a hand to her stomach she felt the rubbery texture of it compared to the rest of her skin, her udder was growing in.
In all her excitement Jeff didn't notice as she ass relaxed for a moment, before she felt a warm cow pat push it's way out of her and splat into her start. Blushing pro furiously she just stood there watching her udder as piss started spraying from her asshole, her new cow instincts having taken over her waste disposal functions.
Watching for a good their minutes the teats on her udder extended to four inches each as her udder grew round and taut, just like a cow's udder. Jeff smiled at the thought of getting milked with a moan of pleasure, pulling on one of her teats. She never noticed how her nipples on her chest had dissapered.
Spreading her legs apart she walked over to the stall door and started waiting again, the sun was rising and soon the farmhand would be here.
