Like most girls her age, 12 year old Cindy wanted to be older so she could do what she wanted. Living on the farm she had always envied the freedom her older siblings had while she was still treated like a baby since she was the youngest in the family.
One day she was milking the cows in the barn and decided to drink some of the fresh milk, not knowing that her father was trying a new experimental growth hormone in the cows feed. Cindy felt strange as she walked barefoot around the stall and bent over in pain on the straw bales. She felt her body grow and expand, not realizing that the growth hormone was causing accelerated aging in her body. Her loose jeans suddenly felt tight as she aged past 15, 16, 17 years of age. She let out a load moan as her body grew feminine curves and her flat chest suddenly grew large breasts, which pushed her t-shirt up on her maturing body like a bib.
She could hear her jeans ripping from the strain of the growth
and when she finally hit 21 years of age it stopped, but by this
time her jeans were in tatters revealing the now long and luscious
legs of an adult beauty. She had gotten her wish.
