Cindy knew just what she wanted. She found the breast(+) vial and gently uncapped it. Being careful to not spill the liquid, she dribbled a little from one bottle to the next. She used the pencil to swirl the liquid as best she could. Soon the magic potion was hidden among the sweetly smelling soap. There was still a little space near the top of the bottle and she wanted to add some more magic. But she really did not want to waste the precious liquid. In the end she decided to play it safe.
Cindy replaced the cap on the breast(+) vial tightly. Then she was shocked to find the liquid in the bottle suddenly full. She could have sworn that the level had been emptied by a quarter. Now it was full once again. Maybe the bottles could not be emptied. If the liquid could not run out then she did not have to be cautious.
Cindy poured another dose of magic into the soap and swirled the mix again. When she recapped the magic bottle it was once again full. She could barely contain her laughter as she made her way back to the bathroom.
She noticed in the mirror that her hair was still magically long. It had been a couple of hours now. Cindy hoped that it would not last for too much longer. Once people started returning home she would have to find a way to explain her longer hair. It might ruin her prank.
Maybe she should test the soap first? Just to see if it would work. Also if people asked she could claim that she was a victim too. No one would suspect if she was a 'victim' too.
Cindy pumped a small amount into her hand and then washed her hands. Shortly after she felt a rising tingle in her breasts. It was the same feeling that she had at the mall earlier in the day. Her breasts started to grow. She high-tailed it back to her room. Her breasts were now a cup size bigger already and the tingle continued. She pulled off her top before it was stretched out.
Cindy lay on her bed watching her breasts become more round. Under her hands she could feel them push out slowly. The feeling of fullness was pleasing. Her nipples were becoming stiff. Cindy loved the feeling of her skin becoming tight. She closed her eyes and reveled in the feeling. She almost forgot to care about how big they would get.
It was nearly five minutes before the tingling stopped. Her breasts ceased growing too. Cindy opened her eyes. Her breasts were huge. They must have grown by four cup sizes. That made her at least a Triple-D. She found it difficult to sit upright. The weight kept trying to pull her forward. Cindy was beaming though. It worked at it seemed safe.
Now she just had to wait for the first person to try it out.
