Tiff and Katie sat down besides each other in class. They had boring English lessons the next two hours. After the first hour of listening for the millionth time about how great Shakespeare was Katie whispered:"Transform or Dare".
Tiff didn't want to do this while they were still in school and said:"not now Katie come on". The teacher asks Tiff for an answer to a question he asked. She answered it. Katie knowing the rules of the game whispered after Tiff had answered to the teacher:"for your transformation you will copy any attribute you concentrate on while you say "copy" and you will get that the attribute this will last one whole day and for your dare you will copy the private parts from this picture in the biology book" she points at a penis that were pictured in the book.
Tiff turned red.
"Katie, what the hell" she said but lost control and started looking at the picture and said:"copy". Trying to save her skin she quickly went to the toilet.
"Katie help your friend with her notes, oke?" the teacher said.
Tiff locks herself in one of the stalls and pulled up her skirt. Her penis was bulging her panties and started to grow outside of the side. Thinking of what to do she caught herself being quite aroused. The penis starts to grow harder. Panicking she takes out her phone and goes to her gallery. She finds a nice model posing for some lingerie you liked. Suddenly she caught herself second guessing. Her penis was erect at a length of 17cm and a girth of 11 cm. She saves the picture for a bit later and starts looking into those weird websites she found on her brothers computer a few years back. After going through some stuff she finds a comic with a girl who grew a gigantic penis with huge balls. she eyed the penis to be a 1.5 meter long and the balls had a diameter of 20cm. After taking a big breath and pulling her panties down she says"Copy".
The now growing balls started push her legs out. She needed to sit down on the toilet as standing was getting increasingly harder for her. Her member had already grown to half a meter and her balls were hanging outside of rim of the toilet. she was started being ecstatic. She slowly moved her hands towards her growing but in a moment of clarity she heard a stall door open and she quickly toke out her phone and looked up the picture of the model and whisper "copy". The Penis and her balls quickly shrank back into herself which made her give out a little moan. Trying to cover her moan up she flushes the toilet. After calming down for a second she pulls up her panties though she found them a bit tight now. Apparently the model had little bit wider hips then she had.
When Tiff came back to class Katie was barely awake. class was almost finished finally. Tiff trying get back at Katie's prank whisper into Katie's ear:" Transform or dare". Katie half asleep says:"transform please"
What will Tiff do to Katie?
What are there plans after school?
