Any change John makes cannot be changed after

Unknowing that the changes he makes, are permanent, John think on what fun he could have with his power. Sure thing, he gives himself a well toned body and a bigger dick, but didn't change too much himself, as he didn't want to become someone else entirely.

Back home John found his big sister Kenya, cooking. She was a tall long haired 21 years old redhead with a nice rack and a pretty face. And she loved to brag about her breasts, to the point that she dressed with tops with low cleavage. Sometimes, like today, she had just a micro-short and a cooking apron, because her boyfriend was eating home.

"Dad and mom are working late, I'll cook for tonight. But can you eat in your room ? Dan is coming soon and I want to have some romantic diner with him." She asked.

John sighed. She was doing this every time. Their parents were working late and she was taking the opportunity to take over the house and have fun with her boyfriend.

"Yeah, whatever..." He just answered.

And with that he snapped his fingers and her breasts deflated in a second. It was a petty vengeance, but it was just brother sister teasing.

"What the fuck ??" She yelled. "My tits !"

"What with your tits ?" John asked.

"They're gone !"

"What are you talking about ? You always been as flat chested..."

"What are you talking about ? I always had a nice rack ! My boyfriend love them !"

"I don't see what you're talking about, you're boyfriend likes you for your personality... That's what you said to me."

"Don't play dumb with me ! I'm not crazy !"

"That's what you say. But here's a picture from last month."

John then show her a picture of her on his phone.

"What the fuck ?!?" Kenya yelled again. "It's photoshoped, is it ?"

"Do I need to call the mental ward ? You can see you're flat chested ! Breasts don't deflate like that..." He said.

"I'm not... I'm not crazy..." She said, calming down and confused.

"Anyway, I'm going to my room..."

He then left the kitchen trying to keep himself from laughing. Kenya stayed feeling like she lost her mind and not knowing what just happened.
