Suddenly Mary couldn't push her sister anymore, estranged she looked at her, she had something on her mouth, playing with it, enjoying the flavor....her eyes opened, totally inhuman. Mary was shocked at this and released her arm!.
-WHAT THE??- Mary was speechless
Jenny gulped down the candy.
-MMMMMMMM.....YEEES!! YEESS MORE!- She roared happily feeling the power that was growing inside her.
Her little body exploded with muscle, filling each part of her, her B breasts disappeared when lizardlike pecks grew like metal plates all over her chest, her spine cracked, growing in size as she slowly towered over Mary.
Dark blue scales started covering her entire body, her top was now shredded to bits as it fell to the floor, and her small skirt would suffer the same destiny seconds later.
Mary was immobilized with fear. Looking at the gargantuan being that her sister was now becoming.
-HAHAHAHAHAHAHA WEAKLING?- she laughed , and even roared, huge claws sprouted from her paws, carving holes on the floor as if it was made of butter, and a long tail started swiping through the corridor.
Soon her head started to change as well, a small but wide muzzle infested in fangs replaced her lips, small horns sprouted from her skull, her mind expanded at the same rate of her body, moaning in pleasure as her mind capacity was becoming dozens of times larger than before.
The scene was unbelievable, Mary was standing in front of her 14 year old sister, now a 7'1" male antro dragon.
- So....- She said caressing her new sheath and balls with her clawed fingers - What i can do with you weakling?-
