"Hm..." Mary said aloud. The milk dripping from her dark nipples gave her an idea. "If I go in public, people will start to think I'm weird. Some criminal might even find out about my absorbtion ability and kidnap me and force me to make liquids for them to sell! I really don't want that to happen. If I were lactating naturally, I would have to be pregnant."
Mary wondered...
She went back into the living room where the vial box was, holding up her breasts because they were quite heavy with milk. She dug through the box, looking for a certain vial. Finally, she found it. The pregnancy vial.
Mary was well aware that she could always reverse the changes with the human (female) vial and that she didn't need to worry about getting kidnapped. But there was a secret desire behind wanting to try the pregnancy vial. She had always been fascinated by the concept of being pregnant. She didn't have kids. She had always wondered what it felt like to be pregnant. But she didn't want to give birth. She didn't want kids.
"Oh well." Said Mary. "Might as well try, I can always reverse it."
She threw her head back and gulped down the pregnancy vial.
