When Valerie got home she saw that her sister was not alone. Her best friend Lara was with her.
"Another guinea pig," Valerie thought with a smile.
She got out a pad of blank pages and pulled out her pen.
On the way back she thought long and hard and decided that she would like to live with her sister. Now that her sister's best friend was there, she only had to think about what Lara should become.
When she had made up her mind, she went to her big sister's room. As she stood in the doorway, Mandie asked
"What do you want here? Get out!"
Then she got the pen and wrote:
"Mandie is now my ass and Lara my feet."
Then she looked back at her sister. Mandie wanted to ask what she just wrote down when she realized something was wrong. It felt like she was getting smaller. In addition, her arms, both, and her head seemed to be slowly being drawn into her body. When she looked at Lara, she saw that what happened to her friend confirmed her suspicions. Valerie watched in amazement as the girls kept getting smaller and plumper. Before either of them could ask what was going on, their mouths were gone.
When Valerie saw that the two piles of clothes weren't moving anymore, she went over to them and gently pushed the clothes aside. She saw two balls of flesh. When she touched the balls with her hands, they were instantly absorbed by her. Valerie then passed out briefly.
When she woke up again she noticed that her body had changed. Her buttocks seemed to have gotten bigger and her feet plumber. Immediately she went in front of her big sister's mirror and undressed. As she stood naked in front of the mirror, she first looked at her feet. They were a little bigger and seemed to have taken on Lara's skin tone. In addition, there was a tattoo over each sole of her foot that looked like one of her sister's best friend eyes.
After that she turned around and looked at her butt. This too had grown, although a little bit more as her feet, and the skin tone had changed here too. Spreading her cheeks, she was amused to see a small tattoo that looked like her big sister's eyes, just above the anus.
Her sister and her friend were visibly confused in her new form when they suddenly heard Valerie.
"You're wondering what happened. I was given a magic pen that turns anyone into anything as long as it's inanimate. I used it to turn you into parts of my body. You, Mandie, were the root of everything bad and I thought about this terrible punishment for you. You are now my new ass. I hope for you that you can't taste anything else, I wish you a lot of fun with my sweat, farts and my shit.
And you Lara were in the wrong place at the wrong time. Since you were there sometimes when Mandie bullied me and I don't need witnesses, I decided to transform you too. You are my feet from now on."
When she was done with that, she thought about what to do with her new power.
