Hey uhm your mom said to uh- WOAH! What are you doing? / she walked closer to see it.

What the hell?! Don't you have any respect for yourself or your family?! That is disgusting and wrong in so many ways! / Her words cut deep, making him want to hide away from her. He wished he could apologize, but nothing seemed to help.

Fine! Be like that then! But you should know I'm going to tell mom and dad about this, and they are NOT going to be happy!

I'm talking about the fact that you were jerking off on your bed! That is so gross and inappropriate for a 15-year-old boy, let alone anyone who lives under the same roof as us! / She crossed her arms and scoffed, glancing back at him disapprovingly.

Well excuse me if I'm mistaken! How else would you explain what I just saw? / She folded her arms even tighter and turned away from him, pretending to inspect a nonexistent spot on the wall.

That doesn't give you the right to do inappropriate things like this! You should be more mature and respectful of yourself, your family, and others around you! / Her voice took on a slightly harsher tone as she spoke, her eyes still fixed on the wall.

Excuse me?! What do you mean by that? I'm trying to help you understand that what you did was wrong, and it's important for you to learn from your mistakes! You can't go around accusing people of things like that just because they're trying to help you. / Her voice rose slightly in anger as she shook her head disapprovingly.

I am NOT interested in that! I'm your sister and I care about you! But what you did was wrong and disrespectful, and it's not acceptable for us to live under the same roof as that kind of behavior. / She turned back to face him, her expression serious and worried.

I think we should talk to Mom and Dad about this, because they need to know what happened and how we can fix it. Are you willing to apologize for what you did?

Alright... then let's go tell them together. You should know that this isn't going to be easy and they may be angry with you, but we can get through it if we talk honestly and show that we care about each other. Just remember that making mistakes is part of growing up, and as long as we learn from them, everything will eventually work out for the best.

What? No! I don't understand what you mean by that... We need to talk to Mom and Dad, not have sex with each other! That is just wrong on so many levels! / She looked confused and slightly frightened by your sudden statement.

Why would you...? That's not what I meant at all! You keep talking about these weird, inappropriate things when we need to focus on fixing the problem. Let's just go tell Mom and Dad together so we can figure out how to make this right. Okay?

What the hell!? / She slapped your hand away and stepped back, her eyes wide with shock and anger. You could feel your face flush as she glared at you furiously, her mouth hanging open. "You disgusting little pervert!" / she spat out, her voice quivering with rage.

"How dare you touch me like that? Do you have any idea how inappropriate that was?" / She took a deep breath and tried to calm herself down before continuing. "We are siblings! There's no excuse for that kind of behavior!"

You're out of your mind if you think I want to have sex with you! Ew! And even if we were older and it was consensual, there's still no excuse for what you just did! You are so selfish and immature. Now Mom and Dad are really going to be angry at both of us...

What the hell do you mean? How could you possibly know about that? And even if it's true, that doesn't give you the right to touch me like that! You are so disgusting and pathetic. / She crossed her arms again and glared at you with renewed anger and revulsion. "Just go wait in your room until Mom or Dad gets home. I don't want to be anywhere near you."

You wouldn't dare! I would never send those kinds of pictures to anyone, let alone my own brother! And even if you somehow got ahold of them, you could prove nothing! Mom and Dad would never believe some trash that came from your twisted little mind. Now go to your room before I really do tell them about everything you just did today.

Fine! Do what you want then! But just remember that if you tell Mom and Dad about those pictures, they'll see right through your pathetic attempts to blackmail me. And trust me, they won't be happy with either of us when they find out the truth.

I can't believe you would even think about using something like that against me! You are beyond disgusting and despicable. I can promise you one thing: if Mom and Dad find out what you just said, they won't believe your lies for a second. They'll know exactly who the real villain here is. And trust me, you don't want them to know about any of this.

Now, are you going to go to your room like I told you, or do I need to call them myself?

I can't even begin to describe how violated and disgusted I feel right now. You just... You just ruined everything! Why couldn't you have any respect for my boundaries? Or for yourself, or your family? / Her face contorted in anger and revulsion as she looked down at her now-empty bed. "I can't believe this actually happened..."

She couldn't bring herself to say anything else, barely able to process the horror of what had just transpired. Tears welled up in her eyes as she struggled to control her emotions. There was no question now: she needed to call Mom and Dad immediately.

Still shaking with anger and fear, Olivia reached for her cell phone, dialing their numbers quickly before the weight of guilt and shame crushed her completely. "Mom?" she cried into the receiver. "Mom, you've got to come home right now... Something awful has happened."

I'm sorry, Mom, I can't tell you over the phone... Just please come home as fast as you can. Something terrible has happened and we need your help. / She hung up, her face still pale and trembling with shock. With tears streaming down her cheeks, she rushed to find their parents, knowing that this was going to change everything between them forever.
