Incest A bit odd, but whatever

"Be quick dear," Susan said from he other room. "I need to fix my hair and freshen up a bit."
She said that, but she already looked great. She always seemed to put in just a little bit more effort whenever Zack was home, whether she realized it or not.
"Right, I need to get some studying done this weekend," Zack said, standing up to leave.
"Uuuh..." Erica hesitated. "Um, d-did you know that... um..." She looked back at the part in the article she had just read.
"What?" her brother asked.
"No, I was just saying, like... Did you know a starfish can regenerate an arm?" She felt butterflies in her stomach as she spoke, rambling and uncertain.
"Uh... okay?"
"Yeah, it's through a process calledMitosis. It's, um, pretty interesting," she finished.
"Right. I'll call you if I ever decide to become a marine biologist," he said, giving her an odd look then shaking his head with an amused smile.
Erica felt a little lightheaded as her brother left to put his coffee cup in the dishwasher. That had been stupid, and not nearly as fun as she had imagined. Well, a little fun maybe.
She heard a crash of porcelain from the kitchen, followed by a gasp.
"Jesus, Zack! What happened?" her mother exclaimed with concern in her voice.
"Um, n-nothing. I just... dropped my cup. I'm sorry..."
"You scared me sweetie. Don't worry, I'll clean that up for you."
Erica froze. That didn't mean anything, did it? She didn't dare to turn around and look.Just... pretend you're reading the newspaper, she told herself.
She hardly breathed while she listened to her mother pick up the pieces of porcelain and her brother excusing his clumsiness.
Surely it didn't mean anything. He just dropped the mug on accident. Not because he recognized the code word. Right?
Fuck, fuck, fuck, fuck, she cursed at her stupidity. She wasn't sure she could live with herself if her brother found out how much of a pervert she really was. If he sat her down to explain how it was inappropriate for her to think of him in that way she would just die on the spot.
Then again, if he had recognized it, didn't that mean he was into that stuff? Or did it?
She could feign innocence. It was a coincidence. She just happened to read an interesting fact online and wanted to share it. That was the point of using it as a code word, wasn't it? Yeah. She could just drop a few more random facts around him and her parents to sell her alibi. It would work. It had probably just been coincidence that he dropped the mug anyway.

Despite her newfound resolve Erica spent most of the day inside her room, away from her brother. She made it through dinner with minimal eye contact and while keeping her expression as natural as she could make it. She hadn't dared look at him directly.
She spent most of the evening listening to music and browsing Facebook. As the calm of evening arrived, covering the street outside her window in darkness, she was finally able to calm down. With idle curiosity she opened a tab for the site she had visited yesterday.
What was it the story had said? What happened after the girl in the story hinted at her attraction to her brother?
Erica found the passage and read it. Then she read it again, and again.God, that sounds even hotter now, she thought. She was getting very excited, the wet spot between her legs screaming for attention.
The girl in the story was supposed to meet her brother in a secluded room of the house at midnight. The laundry room was the room of choice in the story. If he walked in at just the right time and found her on her knees, that would signal they both agreed to act out the events, more or less as written in the story.
Erica suddenly felt warm. Her heart was beating fast and apparently pumping most of that blood up into her face. It was 22.23 in the evening and her parents were just getting ready for bed. What if her brother was doing the same thing she was? Could he be reading the story right now and considering the instructions it gave? Would he possibly ever consider doingthat to her?
No. She was being silly and letting her imagination run away with her. Surely he wasn't. But what if? If he didn't show up she could just get back to bed, feeling a lot more certain that he had never realized anything.
Erica mulled over her options for a little over an hour before coming to a decision. In the end, the itch between her legs that she refused to take care of decided for her. She justhad to find out.
The house was dark, her parents long since asleep. Carefully she opened the door to the laundry room, which seemed to creak much louder than usual. The laundry room lay between the garage and the hall by the front door, which made it the safest room in the house to make noise in.
"Jesus, what the hell am I doing?" Erica whispered to herself.
She looked at her phone. Seven minutes to twelve. She crossed her arms around the t-shirt she had decided to wear over one of her sexiest pairs of panties. No bra. The room was much colder than the rest of the house, sending shivers down her spine.
Time passed slowly as she paced back and forth in the small room. The knot in her stomach begged her to leave. To go back to her room and just forget about the whole thing, but she stayed.
