step-Mom & step-Dad are out for a date night and has left you alone with your older step-sister. She's your typical mean big step-sister, constantly teasing and bullying you. She decides you guys should watch a scary movie together while your parents are both out for the night. You're honestly sick of her bullying you so much so you ask her to tone it down on the teasing and trying to scare you during the movie like she usually does and surprisingly she happily obliges! She starts to take a liking to being a loving big step-sister and notices you have to.. maybe, a little TOO much of a liking... I wonder how far this step-brother step-sister relationship will go
