Stepsister Threaten Into Creampie

Wha- hey!! You aren't supposed to be here! Aren't you on vacation? You're home so early... Oh. My. God. You weren't supposed to find out! Okay, yes, I had a little party. So my friends wanted some fun. So what? I know it's yours... wait, I need to make it up to you?! No, I don't know how much it cost! I'm not even old enough to buy it in the first place so how am I supposed to fix this? .Are you serious? No, I'm not a slut! I don't just do sexual favors to anyone... are you kidding? Gross! Why- you're serious? You're going to kick me out if I don't listen?! Oh my god, I can't believe this. I mean, I know I really messed up and I'm sorry. But please, please don't kick me out. I love living with you! I'll do anything to stay! ...This stays between you and me, right?
