This is bad. Very bad. He's rubbing off on me. Resident bad boy Ethan Colton is turning me into an irresponsible bad girl. ----- Rule #2 – When I tell you to come here, you come here. It's still an order, still practically growling at me, commanding me to obey him, but it's more, too. It's fun and flirty, a little playful. I can see why girls fall for him, can see why his devious smirk melts their resistance, because it's doing the same to me. 

I thought I was a good girl, but then why do I love hearing all of the naughty things he says he wants to do to me? ----- Rule #3 – You can change your mind, Ashley. Not just now. Whenever. I could tell Ethan that the only thing I'll regret about this is that we only have a week together. Except I can never tell him that. I need to stop. I need to understand that this is a temporary situation and that I'll never have it ever again, because no matter what, it won't work out, whether I want it to or not. 

I don't know when it happened. I didn't think it'd ever happen. I can't lose her. I can't even imagine losing her. ----- Rule #6 – This is supposed to be fun. Understand? He's my bad boy and I'm his good girl. And, yes, he's my stepbrother and I'm his stepsister. He wasn't always, though. We aren't just that. There's a lot more to us. Sometimes you need to follow your heart, or else you'll regret it for the rest of your life. You don't always have a choice in who you fall in love with. Sometimes you can't be perfect. You just have to be yourself. Sometimes that's what makes you perfect.

"Friends with benefits, stepbrother with benefits, what's the difference?" ----- Rule #1 – It's only supposed to last for a week... ----- Ethan is a cocky, arrogant jerk. He's always been that way. Why do girls trip over their own feet just to be with him? I don't know! I'll never understand it. Don't they realize he's just going to ditch them after a couple of weeks? Yes, he can be nice when he wants to be. It's true that he's ridiculously attractive, too. It's not like I want to stare at him when he walks around shirtless, but it's hard not to notice someone like him. He's got that bad boy smile that makes you want to... Did I mention he's my stepbrother? Ick. What? You think I'm falling for him? Nope! It's impossible.

"It's not just for a week anymore, Princess. A week isn't long enough. I need more. I need forever."Rule #12 – You can tease me, Ethan, and we can play, but you can't be mean to me. I need to know that there's more, that this isn't wrong, that you feel the same way I feel...I never wanted to hide this from you, Dad. It wasn't about that. It wasn't that I was ashamed or thought I was doing anything wrong, but I didn't think you'd understand and I wanted to be with Ashley. I want to keep being with her, and whenever I thought about telling you, and then thought about you getting mad about it... well, yeah, that's it.How am I supposed to date her if you're angry about us dating? That's why I didn't tell you. This isn't a fling to me, it's serious.She's too much, but she's never enough, too. When I'm with Ashley she's the only thing I can think about. When I kiss her, I mean it. There's a difference there, a difference between just kissing, or kissing because of lust, or a sweet and nice kiss, or kissing because you really mean it. There's all sorts of different kinds of feelings, but that last one is the most important. That's the one I feel when I'm with her.It's crazy. This entire thing is crazy. I love it. I love her.

How can something so wrong be so perfect at the same time? ----- Rule #5 – I'm going to show you some things that you'll never forget. It's wrong. Not just this, but everything. I knew it was wrong, but I thought I could get away with it. Why, though? I'm not like this. I'm good. I'm the good girl, the girl with perfect grades, the girl who does everything right, prim and proper. I don't cause trouble, I don't get into trouble, I don't... It's only a few days, right? That's what I thought when Ethan and I started our stepbrother with benefits situation. Apparently a few days can be a long time. A few days can change your entire life. 

I was never supposed to fall in love with my stepbrother. I never intended to. It just sort of happened. ----- Rule #4 – You can change your mind, too, Ethan. We can't. We're done. This girl lives in the same house as me. Her bedroom is just down the hall. It barely takes twenty seconds to go from her room to mine, and yet it's an impossible distance now. She might as well be on the sun. Ashley knew what was coming. I knew, too. Why can't I stop thinking about her, then?
