Scientist Dahlia's boss, Katana, is such a prude! She's always making comments about Dahlia's low cut tops, so Dahlia decides to get revenge. Using a specially formulated milk, Dahlia secretly begins to grow Katana's tits until they're bursting out of her top. Katana is completely oblivious until her tits are huge, heavy, and full of milk. She begins to helplessly moo as Dahlia massages her new tits, and is programmed into a mindless, pleasure-driven hucow. Dahlia is delighted with her new pet and intends to turn the rest of the lab staff into cow drones just like their boss.
