“And now we have a unique opportunity.” Mary said and then she scrolled the tags up to the "Mythical" section without paying attention to that. The vial on her hand was still a ‘Syberian Tiger’ and when she put it back on its place, its label changed to ‘Classic Red Dragon’. Next to it, there was several other dragon vials, such as oriental dragon, wyvern, hydra and so on. Each kind of dragon came on several color. She picked the ‘Classic Red Dragon’ vial and opened it.
"I am amazed at how this thing works." Jeff said, referring to the box itself.
"Well, just one way to tell." Mary said as she gulped down the content of the vial on her hand.
“Are you crazy?” Jeff shouted. “What if this thing is a poison?”
“Well, I don’t think someone would have that amount of work just to poison us. And I think that I… arrrrrgghhhhh!” Mary shouted as she felt a stinging pain on her rear end.
“What happened?” Jeff was worried as he saw Mary fumbling with the zipper of her jeans. But before she could unbutton it, they heard a ripping sound and her shorts and panties fell to the ground, shredded. Behind her, a thick tail sprouted quickly and lengthened until it was four feet long.
"What is that?" Jeff shouted.
“I am growing a tail!” Mary said, surprised.
Jeff approached Mary’s new appendage and took a closer look. She indeed had a tail now and it was the same color as her skin. It was hanging down to the floor and laid there, motionless.
“Incredible!” Jeff said. “Can you move it?”
Mary concentrated and Jeff saw as her tail wiggled a little before going limp again.
“It is hard; I don’t know what muscles I have to move to move it.”
Jeff then noticed something else.
“Hey! Your tail is still growing!” He said as he saw that her tail snaking further in the ground. It grew two more feet in just a couple of seconds.
Mary looked back and moved her ass, so she could see what was happening. She was startled to see that her tail moved up suddenly.
“I thought it was hard for you to move it!” Jeff said.
“I thought so too. But when I tried to see it, it moved almost on its own.”
Mary then tried to move her tail again and this time it waved and snaked on the floor.
“I can move it now! It is so easy now!” Mary said, excited, while she wrapped Jeff's legs in her tail to prove that.
"What kind of vial did you drink from?" Jeff asked, concerned.
"It was this one, the 'Classic Red Dragon'." She answered.
"Aren't dragons supposed to be as big as a bus?" Jeff asked.
As to emphasize his words, Mary felt a vertigo and Jeff her growing a foot in just a few seconds.
