"Here it is! The prototype growth formula I've been talking about. We still have to dilute it a bit for the market. Just a little bit is enough to make you jump a few cup sizes!"
"Uhh, that's really cool and all, but I think you spilled a little on your chest..."
"Huh?"
You hear the sound of buttons popping as the young woman's top slides away, revealing much larger breasts than before.
"Um, bad news, you spilled a bit more on yourself during that burst of growth."
"Mmmn, what?"
Her breasts expand further, smashing against the table with a loud thud.
"*Huff* *Huff* Is it over? Fuck...I'm going to lose my job."
"Uhh, bad news... you spilled the cup on the table..."
One week later:
"Oh hey, it's been a while. I haven't seen you since the, well, incident. They don't want news of the formula getting out until its ready, so they're keeping me in this room while running some tests to see if they can return me to my original size. Between you and me, I hope they don't find a way to reverse the growth. It's oddly fun being more breast than woman, hehe."
