Really enjoy it myself.
I was thinking after the humiliation part. That girls leave her in a room with some stoners. Smoking weed.
Weed often has the affect of causing people to loss inhibitions. So Sammy being a Rude arrogant slut would be amplified.
Maybe she would do stuff like call other girls jealous of her perfect boobs and remove her own top to make the point and that she was gonna steal all the guys attention away from them. Telling them they will never get any the guys while she there

(really she just making bad choices out of spite under the influence.
Cause her sister can record this behaviour. And Sammy being a cheerleader would have pass a drugs test in order to stay on the team. Which means she have do what ever Courtney says in order to have her pee in the sample jar.
I just like create my own thoughts sometimes but love the story fantastic work!
