With you froze up on the couch, not able to move an inch, your sister was looking at her hands. Her nails grew a tad longer and were now more natural. Her skin became flawless and more tan, she could feel her body slowly changing into something perfect.
Now looking at herself into the wall mounted mirror in the living room "Wow, is that really me?" her hair had just change to a golden like color and was now the most soft and durable fiber on earth. Her ass and boobs felt more full in their clothes. She fondled her breasts a bit for fun "Hmm, they feel great, and are more sensitive, I like it" she smiled at herself in the mirror.
Upon watching in the mirror, she saw you still frozen behind her "Well well, I almost forgot about you, big bro" she snapped her fingers and you could now move again "WHAT THE HELL, YOU B.." but she snapped her fingers again, freezing you stiff for a second time "I thought I've been clear about this, I want you to shut up, but you don't listen well, guess I'll have to teach you a lesson" she was wondering what to do to you when she thought of reading your mind instead.
You were wondering why your sister was looking at you the way she was, but you suddenly felt a slight headache. For some reason you though of the inevitable, she was reading your mind.
"My my, there's a lot of nasty stuff going on in your head" she giggled giving you a mischievous grin. She then snapped her fingers and you could move again, this time, you just looked at her and said nothing, for fear that something else bad might happen. "Wow, I didn't know you were in this kind of stuff" .. "What kind of stuff?" you replied.
She gave you a playful smile and started growing "This kind of stuff" she said, feeling herself expand in her clothes. "Get up, I want to see you shrink before me as I grow taller" you felt your body comply to her order and you got up even though you didn't intend to move. You watched your once little sister rising up before you. Her head was slowly coming up to meet yours. Her black skirt rode up past her knees and brush against her legs as it became more like a mini skirt. Her feet grew in her sneakers and were now pushing on all sides to get free. Her black tank top rose slowly above her well toned abs and her now well rounded breasts were pressed against the fabric, she grabbed them to feel them expand in her hands.
Your sister had her eyes closed "Ohh this feels sooo good, don't you agree, bro?" you could only watch as her head was now above yours and getting away. Opening her eyes, your sister looked down "Ha ha, how do you like being smaller than me now?" she said pushing you lightly "Hey stop that" but that only fueled her to push once more "I said s.." before you could finish she snapped her fingers and your mouth disappeared "You're annoying" she putted her hands on her hips and continued to grow, looking down at you with menacing eyes. Her clothes were about to rip completely when she willed them to grow with her "Hm much better that way" just then, your mouth reappeared on your face, you ran your fingers across your mouth to be sure it was really back "From now on you better shut up bro, I can do whatever I want now and you better let me do anything I want to you" she then walked over to you and stood inches from your diminutive form. "Wow, this is awesome, just look at how small you are now" your face was level with her belly, you look up to see her smiling "What's wrong little brother, don't like having a big and beautiful sister like me?" you watch as her head now hit the ceiling "Oh my" she giggled.
