“Oh! Gosh, I’m so late!” cried Kimmy, her long brunette hair trailing behind her as she rushed to the train station. She could feel her skirt riding up, exposing her panties to the crowd, but she didn’t have time to slow down. “I’m gonna be so late for school!” Feeling that her large, heavy breasts were swelling even larger and bouncing with every step she cradled them in her arms, worried that they would snap her bra. As she skipped through the gates and pushed through the groups of strangers she barely forced her way into the packed train car, sighing with relief as the doors closed. Ahh... finally... she thought, I made it... Shew thought as her breasts pressed against the glass door, spreading out and giving the people waiting on the platform a show. Looking down, she saw a pair of familiar wet patches building in the front of her uniform. Oh! I forgot my lactation pads today... I’m going to leak right through my clothes! My titties are going to be so enormous...

It was incredible to see a young, tiny high school girl with such incredibly back-breaking boobies, but even more strange for one who was lactating through her bra. The secret was that Kimmy hadn’t always been Kimmy - a month ago she had been Donald, an anime-loving high school student who got good grades but loved watching hentai on his nights off. His original character Kimmy, a chesty, clumsy high-school girl whose tits grew and grew with milk all day was his favourite. He wrote a few short stories before paying a talented underground artist to draw Kimmy for him. After a few days, he got back a piece of art that showed her just as Donald had imagined her - a short, cute girl with giant knockers, squeezed into her uniform as she struggled to hide the growing wet milky patches building in the front of her shirt. However Donald failed to read the fine print on the commission contract, and when it came time to pay, the artist had a different form of repayment in mind: As Donald looked at the picture for the first time, he felt himself pulled into the screen, and before he knew it he was inside the body of Kimmy, expressing her large, sensitive breasts into a bucket at the end of a long day!

“Oh gosh, this is even worse than normal...” Kimmy whispered, the milk now leaking into his shirt and making the fabric transparent, allowing the strangers on the train to see his tits as they strained in their bra. A group of high-school girls giggled and gossiped among themselves watching her struggle and a pair of salarymen began to lick their lips are the sight of an enormous pair of barely legal breasts on display for the public to see. Kimmy couldn’t wait until she got to school... not realizing that the first period of the day would be gym class, and she’d forgotten her gym gear too.
