Belle asked: "So, who wants to be next ?"
Before Belle's father or twin sister could answer, her youngest sister raised her right hand and claims: "Transform me !!!"
Bell nodded and used her eyebeam on the 5 years old girl, whose skin turned purple. Her clothes dissolved, leaving her completely naked She then began to age up quickly, at a rate of 1 year old every 5 seconds.
30 seconds after her transformation began, she had the body of an 11 years old, just starting her puberty. Her feelings for Belle began to change: she was not only her cool super-sister, but her crush as well. Her feelings for Light, Thunder and Witch changed as well. 30 second later, she is as tall as her super sister, with C-cup breasts and she is a stunning 17 years old girl. With her complete lack of body hair and her purple skin, she really looks like an alien.
"So what is your superpower ? Besides being almost flat-chested and purple ?" asked Witch who was proud of her G-cup boobs.
Without saying a word, the purple sister's body began to change, as she took the exact appearance of Witch, cloth included.
"So our little sister is a doppleganger" says Thunder.
"My name is Violet, and I can do more" says Violet as she changed her appearance to become a perfect copy of Thunder. Then, she began to grow bigger and bigger until she reached the ceiling. Finally, she schrank back to normal size while changing her appearance again to copy her father's body, including his boner. She also stretched her right arm to reach her father who was opposite to her at the table and began to stroke his dick while she was stroking her own dick with her left hand.
"That's gross" said Light who still rememberd she had been a boy.
Violet smiled and reverted to her default form: a naked 25 years old purple woman. In this form, she kissed Belle, thanking her sister for this wonderful gift.
