Her sister

Carrie's annoying little sister, her name was Cassidy, she is 4 years younger, she is the stereotype of a popular school girl, blonde with big blue eyes, a cheerleader and has a body that all girls envy and all boys desire but you knew she was a kick in the ass she was arrogant smug and self centered.

In the last 3 months Cassidy never approved of her relationship, she said that Carrie deserved someone better and she was always an obstacle between you and Carrie, although you have learned to endure it over the months.

Then you remembered the changes you made to your girlfriend turning Carrie into a sexy slob but you did not think how someone like her sister would react to these changes quickly you tell Carrie to run and hide admiring her plump body shaking herself to the bathroom.

"You again! I thought I wouldn't have to see you until Monday," Cassidy said angrily

.- I had to bring your sister home but I'm leaving right now

You still couldn't get out of there, Carrie was in the bathroom transformed into a slob wearing nothing but a hoodie, you had to do something...

Then Cassidy exclaimed

.- Wait, where is my sister?

.- In the bathroom you answered

.- Wait a minute, I can't find my phone and I think I forgot it in the bathroom. Don't you have it?

.- No but if you are so worried you can ask Carrie if you forgot it there

Then Cassidy slammed on the door desperately

.- Hey Carrie, I didn't forget my phone in the bathroom, did I?

.- No it's not here maybe you left it in the kitchen she said with her new voice deeper and gruffer

.- I looked for it in the kitchen and it's not there, ugh, it's that horrible stench, it smells like unwashed body and flatulence. What did you eat? Or did you skip the shower these last few days?

It was common for them to argue but Cassidy was always quite rude.

.- As I told you, your fucking phone is not here, so why don't you go looking for it in your room?

.- Well I'll go find it there and I hope your fucking boyfriend isn't here when I get back!

So Cassidy went upstairs to her room giving you time to think about what to do with Carrie when she opened the door to give you something...

It was Cassidy's phone...

.- I'm fed up with her so I have a plan to give her what she deserves, I downloaded the app which changes people's stats maybe you can do something so she doesn't notice my changes and to change her horrible attitude

Then Carrie gives you the phone, letting you decide what changes to make to her own sister ...
