Mary was a cute, young student at her high school. Her boyfriend, Todd, was a big science nerd and he had been saving up all year long to order these special vials, since they were both really big into science fiction and transformations.
When the big box of vials finally arrived, they quickly cut the box open and saw all the vials neatly packed together in foam so that they were well-protected in the box.
Each vial was clearly labeled indicating what the serum's effects were. Todd and Mary carefully lifted each vial out of the box and studied them.
"Ohh! I'm so excited!" Mary cheered. "I can't wait to try these!"
"Yeah! I want to try the body modification ones for sure!" Todd grinned.
"I want to try the animal ones." Mary noted, as she found one vial which caught her attention right away. "Look! I found one!"
Mary carefully pulled a vial out of the box. It contained a blue-colored liquid and the label said "Fly".
"Yes! This is it! I want to try this!"
Todd just stared at her.
"You... You want to transform into a fly?" he sighed. "But... Why?"
"Well... What if I only drink half of it? Then I'll become a human fly instead!" she insisted.
"Okay, well... Make sure you know what you're doing!" he smiled.
Mary had long, brown hair and blue eyes and she was about average height and slender. She was 16 years old.
"Are you sure that's what you want?"
"Yeah!" she replied.
Then Mary removed the cap from the vial and she drank exactly half of the serum before she put the cap back on.
"Umm... That wasn't so bad..." she said, before she sat down on the couch. "I'm feeling a little tired..."
Todd walked into the kitchen and started making sandwiches while Mary sat on the couch, waiting for the vial to take effect...
