Joce's breasts wobbled and shook within their confines, and Peter couldn't help but stare at them. They practically defied gravity, with the way the bobbled and swayed. Joce poked him, and he broke out of his awe-driven stare. "Now, what comes next?" He asked.
"P", said Joce happily, as her breasts bounced forward another cup size. "Then Q and R!" She said, he breasts bouncing forward once more. The black lace bra which had been straining against this oncoming wave of growth finally snapped, and her breasts bounced free, standing high with the perkiness of a high school girl's despite the huge size. "Then S . . . Ohhhhhhh!", she started before deteriorating into a moan. Peter looked at her with concern. "Feels . . So good! Filling up!", she said breathlessly. Peter looked down at the orbs which had begun a wobble strangly of their own accord. As Peter watched, they continued to do so, until finally, Joce stopped.
Joce looked at her breasts in a new light. Peter gasped. Dangling at the end of Joce's bottle cap sized nipples were tiny droplets of milk. Joce smiled, and her face flushed red. Peter gently grabbed her nipples and squeezed them, and was rewarded with a small stream of milk spraying out. Joce moaned slightly, and Peter smiled. "Shall we continue? What comes next?" Joce smiled, and continued. "Next comes T, The U, V". her breasts counted forward as they grew once more. "Then W, X, Y, and Z!" She finished. By this stage, her breasts were massive, each the size of a watermelon - or larger.
Joce smiled, and milk once again began to fill her, until it dripped from her nipples. Peter grabbed her nipples and brought them to his mouth, and begs to suck. Milk flowed into his mouth, and Joce began to moan loudly. He continued to drink, and while he did so, he thanks whatever had made this possible.
