"... Give milk. Lots of milk. Ten gallons of milk to be exact, and it must be drunk by at least 20 different people", Karyn said with a sly grin. Jon stared at her in disbelief, dropping his breasts in shock and wincing when they bounced heavily.
"WHAT?" he squeaked.
Her grin grew broader. "You have to produce at least 10 gallons of milk, and at least 20 different people have to drink it, within a day of it being produced. They have to drink it knowingly and willingly, and you can't use the stone to help you or make them disappear. If you try another pair will appear under the first one as a penalty, and the numbers will double. When you've reached the goal your breasts will go."
"You can't be serious!", Jon yelled.
She ignored him, and carried on. "Your breasts can each produce about a pint per day, so 10 gallons will take a minimum of forty days. Of course if you don't milk them, they will just fill up and slowly leak, but the milk production will slow down considerably. We don't want them to pop, do we?"
Jon was practically in shock. He'd never expected Karyn to do something like this. His breasts were aching a little, he guessed because they were so full, but the pain was becoming easier to bear as he got used to it. When he turned around to look in the mirror his breasts swung back and forth, lagging behind his turning torso.
Behind him, Karyn added "No-one will find your breasts unusual, just like you didn't notice them earlier until I wished you would. Whether this means you'll find that you can persuade anyone to drink you milk I have no idea, but it should be fun finding out don't you think?"
He didn't really pay much attention to her, engrossed as he was in staring at his weird reflection. His shirt was tented out several inches by the breastflesh, and the top three buttons had popped open revealing a deep cleavage where his his breasts were pushed together by his shirt. He could see large bumps where prominent nipples pressed insistently against the material, and realised that there were already small damp spots on his shirt over the nipples where milt was leaking a little.
Whenever he moved the damn things swayed ponderously, and when they did his new large nipples rubbed against the cloth with a peculiar sensation that he wasn't entirely sure he liked.
after a while he raised his eyes to meet Karyn's in the mirror, and said...
