Jeff stopped the truck and Mary jumped out of it as quick as she could. Jeff walked to her side and saw that she was now ten feet high, with a ten feet long tail attached to her back. Her shirt was straining to the burst point and her neck was four feet long. Her legs were digitigrades and her claws were menacing.
“We are already near our cabin! It is just behind that mountain! Climb on the cargo bed and I will drive us there.”
Mary climbed on the back of the truck and Jeff resumed driving. He opened the passenger window when he saw that Mary’s head could reach it. She put her head through the window so she could still talk to him. Jeff drove slower to avoid accidents.
“Despite our hurry to go to a safe place, I am enjoying my changes!” Mary said in a booming voice.
“Wow! If I did not see what is happening to you, I would never believe that someone could change into a dragon! Will you be wild when your changes finish?”
“I don’t think so! The note on the box said that my mind would remain human, so I don’t think there is any danger to you.”
“Are you changing more? I think your head just got bigger!”
“Yes! I grew out of my shirt and bra just now and I think my hands are changing too!”
Mary looked back at her hands and noticed that she had only four fingers now, her thumb and three digits. They were growing four inches claws each. Her tail was even longer now and was starting to hang out of the cargo bed. She returned to the window to talk to Jeff.
“Are we already there? I am still growing and I almost can’t fit on the truck anymore. My hands are changing into some kind of paws, with really big claws.”
“We are almost there.” Jeff said as he looked at her. “Hey! Your eyes are different; they are slitted and yellow now!”
“Are they? Wow! This is awesome!” Mary said as she looked at the vanity mirror on the cabin.
“Do you really like what is happening to you?”
“Of course! That vials box was the best thing that could happen to us! And I think you are enjoying it too, since little Jeff is almost bursting free from your pants.”
“It may be, but you will be too big for me when you finish changing and I don’t feel like changing myself. My fantasies were all about old plain me having a relationship with some other creature, especially if I can see the changes happening!”
“This is easy to accomplish now. I think I can be a different animal each day just for you! Imagine how you would feel if you get home from work and find me starting to change into a different creature.”
“That would be great!”
Then Jeff looked at Mary again and saw as her head started to change.
“Mary! Your head is changing!”
Mary looked at the now tiny side mirror of the truck and saw her mouth pushing forward into a small snout while two horns grew on her forehead. Her teeth grew sharper and longer. Her nose fused to her face while her nostrils became larger. She ran her tongue on her new lips and found out that it was now forked, flatter and longer than before. Jeff saw in the rearview mirror that Mary’s body was growing again and felt like the truck was almost overloaded. He stopped to check on Mary’s new changes and saw that she wasn’t fitting the cargo bed anymore.
“Mary, I think you will have to get out of the truck. You seem to be way too heavy for it now!” Jeff said.
