Part 2
Lily paced the length of her room with her nails between her teeth. What had she done? She couldn't believe that's she'd just shown herself to her brother like that. She was his blood. They'd come from the same woman and they shared an upbringing.
Still topless, she stared at herself in the bedroom mirror. She couldn't understand why Zack's body reacted so much. Lily didn't think of her body to be anything special. Yet Zack seemed to think otherwise. She couldn't help but keep the image of Zack's cock in her mind.
She loved the feeling it gave her. The way his eyes traveled over her naked skin. It was a feeling unknown to her. She wondered if this was why most girls nowadays would wear little clothing. Why so many young women would flaunt themselves for a man's attention?
Despite the attention coming from her brother, it made her feel different. It gave her confidence and a buzz like nothing else in this world.
She thought of her brother's penis again. The first penis she'd seen in the flesh. It almost didn't look real. She remembered how her breath had caught in her throat the very moment he revealed it to her.
It was so large, red and angry all at once. The girth of it surprised her. Zack wasn't exactly built like an athlete, so she was expecting something as slender as he was. In the privacy of her bedroom, Lily removed her shorts and looked down between her legs.
Her thighs were almost stuck together. Her goo had dribbled between her legs and meshed against her muscles. She grabbed a towel from the nearby closet and rubbed away the wetness. And still, her vagina throbbed like a sore ache or as though it was an itch needing to be scratched.
For the first time in a long time, she let her hand find her slit. She was soaked. Between her folds, she felt her skin to be slippery and wet. She rubbed a delicate finger over her ache and she shuddered at the feeling.
Thinking better of it, Lily grabbed her dressing robe and made for the bathroom. She washed herself down and cleaned away her juices from her thighs.
Meanwhile, downstairs. Zack collected kitchen roll and was currently wiping away his spunk from his crotch. He couldn't believe how much had come out of him. The image of Lily's natural breasts was imprinted into the darkness of his closed eyelids.
She was so beautiful, sexy even. His own sister, the girl he'd grown up with was now a woman. The first woman he'd seen in most of her glory. He thought to himself as he cleaned the remnants of sperm from his stomach that Lily's naked body was most definitely an upgrade from porn.
He remembered exactly what her nipples looked like. How pink they were with little spots around her darker shade of pink. How full her tits were, how they jiggled and bounced whenever she moved. He couldn't forget about her thong either. A black thin strap connected the main patch to the string. How her puffy mound stuck out between her thighs, not to mention how wet she had been.
Zack felt himself grow hard again just thinking about it all. He returned to the den and shut the tv off, before retreating upstairs. He wanted to knock on her bedroom door but thought better of it. Tonight something had happened and he didn't want to overdo it.
Instead, he retreated to his bed and jerked off one last time before bed. The image of his sister's body happened to be the subject of his fantasy.
The next day Lily was gone by the time Zack pulled himself out of bed. The car in the drive was missing and he assumed she'd left for some groceries. He woke with an erection as strong as the previous night. He felt himself throb and ache along his shaft. He wanted to see her again.
With the house empty, he ventured downstairs into the den. He looked around at the area where it had all happened. He had been about to leave when he saw the same stain on her beanbag.
With his thoughts getting the better of him, Zack approached the beanbag ever so slowly. The patch had seemed much smaller in the dark. Now as he stood over it he couldn't believe how much had come out of her.
Curiously, Zack bent down and held his nose above the wetness. The scent was strong and pungent. Funnily enough, Lily returned somewhat twenty minutes later with Walmart bags full of food and goodies.
Zack opened the door for her and she stepped into the kitchen before letting the heavy bags drop to the kitchen floor.
"You're up early." He said.
"I didn't sleep much last night." Lily said, not looking at him.
"You weren't traumatized, were you?" He joked.
"No, not exactly." Her voice was cold.
"Is there something wrong?" He asked.
Lily turned to face him. "Something wrong? I wouldn't call what happened last night something right..."
Those were words he'd hoped not to hear. It was clear by the look on her face that she regretted what had happened. It was a look of shame, of guilt and embarrassment.
"What happened last night cannot happen again. It is a secret we must keep between us." She said, folding her arms as though to comfort herself.
Zack felt his stomach drop with disappointment. "I thought you enjoyed it?"
"What does that matter?" She asked.
"Need I remind you that you started this whole thing." He said, frowning.
"Brothers and Sisters aren't meant to do that sort of thing, Zack." She looked as though she could cry.
"Then why did you do it?" He asked.
"I didn't know... curious I guess."
"It's not like I'm going to tell anyone." Zack tried to approach her but she stepped back.
"What happened must never happen again." She said, shaking a little.
Zack didn't know what had changed. She looked guilty, that was obvious. He thought that maybe it was similar to how he felt when she had hugged him. He remembered the washing feeling of shame. To have been so turned on by his sibling, it was as though he felt ill, sick or demented.
"You looked like you enjoyed it." He stated. Trying to remind her of the moment they'd shared.
"Regardless. It can't happen. Not again. Not ever." She said, looking as stern as only she could look.
Zack didn't say much else. He left her alone in the kitchen. She was treating him as though he was the cause of it all. Yet she was the one to initiate the entire thing. Cursing her under his breath he retreated upstairs into the comfort of his bedroom.
Lily didn't appear for the rest of the day. He saw her again around seven o'clock when he came down to eat something. She happened to be in the den again. Though this time she was lying on the couch watching Prison Break. He decided to ignore her and continue into the kitchen.
He made himself something to eat and took notice of the heavy rainfall that battered against the kitchen window. A storm must have rolled in. He looked further out of the window onto the main road and saw large puddles collecting water by the drainage areas.
A sudden spark of light saw lighting strike further down the road. He finished what he was eating and thought it better to check up on Lily.
"Have you looked outside?" He asked her, whilst stepping into the den.
"Is it raining?" She asked, clearly alarmed.
"There's a storm outside. How loud is that TV?" He asked, gesturing towards the television.
Zack grabbed the remote and hit the mute button. Just in time for a loud grumble of rolling thunder to shake the foundation of the house.
"What the?" She said.
"I know! Look outside." Zack gestured towards the window that looked out onto the yard. Lily tugged the curtain open. He was right there was a storm outside. She then remembered the clothes that she had hung on the line a few hours ago.
"Oh shoot!"
Lily sprung to her feet and rushed past him, fleeing from the room. Zack followed her and watched as she made her way out into the rain. She ran as fast as she could towards the clothing line.
"What on earth are you doing?" He asked, speaking loudly above the whistling wind.
"What does it look like I'm doing?" She called back.
Lily darted around the yard trying her best to collect all of the clothes that had been hung up on the line. Zack sighed, knowing that she needed his help. With a deep breath, he stepped out into the lashing rain. The wind immediately swept him back and he thought for a second that this might be dangerous.
Ignoring that thought, he ran around alongside her, unclipping the pegs that held the clothes up on the line. Lily grabbed as many clothes as she could, as did Zack. Eventually, they collected all of the clothes and rushed back inside.
Once inside Zack shut the door hard behind them and they both dropped the clothes to the kitchen floor. They looked at each other and realized quickly that they were both totally soaked. Thankfully, Lily found the funny side to it and they both began to chuckle with laughter.
That was until Zack noticed the outline of Lily's pink nipples against her soaking white top. She neglected to wear a bra today. He thought that to be reasonable considering the circumstances. Though now with her shirt becoming wet, she was practically flashing him all over again.
Lily noticed Zack's face change. "What is it?" She asked.
Zack pointed towards her chest. Lily realized what had caught his attention. He could see her nipples again. Despite having seen them just last night, she quickly covered them with her hands.
"Why bother? It's not like I don't know what they look like." He joked.
"Ha ha very funny." She smirked.
He couldn't lie. He was delighted to see them once again. Her two breasts were centred by small pink nipples and it was a sight he could get used to seeing.
"Why don't you dry off? I'll sort the clothes." Zack said, hoping that this would make her lighten up about the whole thing.
She smiled warmly at him. "Thanks."
Zack remained in the kitchen, deciding to load the dryer with their clothes. He kept out the items that he thought might shrink and added a tab to the roller. He then returned to his room to change his clothes and found Lily downstairs in the den afterward.
"Still cold?" He asked.
Lily was shivering on the couch. She now wore a fluffy pink hoodie that she'd bought only a few days ago. On her legs, she wore tight black leggings with slippers on her feet.
"I'll turn on the boiler." He said, before disappearing to find the cupboard below the stairs.
Just as he had been about to crank up the heating. Everything stopped. The lights blinked out and the energy was zapped from the house. The power cut plunged them into deep darkness. The house was poorly lit at the best of times and with the power out, he stood in complete darkness.
"Zack!" Lily called from the den.
"I'm through here." He said.
Lily had the torch lit on her phone and approached him from behind.
"I think we're out of power." She said.
