Mary looked down at the udder which protrudes from her body and sighed. It would be a slight problem to go around like this. Then another vial caught her eye, marked with switch. She picked it up. On it, the instructions outlined that she had to think of a body part, then another, then drink it. It would then transfer everything from the one thing, removing it, to the second object pictured.
Mary grinned. This was a perfect solution. She thought of the udder, then of the one place where it made sense to hold milk - her breasts. Then she gulped down the vial. Immediately, the large udder began to shrink. It slowly grew smaller and smaller. At the same time, her breasts began to swell. Larger and larger they grew, as the udder shrank and shrank. Soon, the udder was completely gone, and on her chest sat 2 huge watermelons, each barely drooping at all. The milk began to flow in, and soon her breasts were filled with the creamy substance. Her nipples had grown to an inch long, and were now a deep deep brown, as if soaked with something. Two tiny droplets of milk emerged from her nipples, and she gently brushed them off, on to her finger. A moan escaped her lips as she did this, and realized that her breasts were now as sensitive as her udder had been.
Mary looks downward at her dripping orbs, and estimates them at least KK cups, of not larger. Tiny droplets leaked out of her nipples and ran down her underboob. Well, she had solved one problem, the problem of visibility.
