Ethan was deeply immersed in his video game, with the sounds of gunfire and explosions filling the room. His team was winning, and it was shaping up to be a fantastic Saturday.

Suddenly, a knock on his door jolted him, causing his hands to jerk on the controller and causing him to lose focus for a split second.

"Fuck!"

He missed an important shot, allowing the enemy team to gain an advantage.

"Ethan?" The irritating voice of his stepsister, barging into his room without invitation, increased his frustration.

He ignored her, refocusing on the game, but she lingered at the door, expecting him to acknowledge her.

Irritated, Ethan finally paused the game and turned to face her. "What do you want, Ava?" he snapped.

"Well, Ethan," Ava responded with a smirk. "I have a little favor to ask of you."

Ethan rolled his eyes. Ever since Ava and her dad moved in, she has been constantly bothering him with her requests and demands. She was like a spoiled brat who always got her way.

"What is it this time, Ava?"

Ava's smirk widened. "I need some pictures taken, and I've seen that you have a fancy camera. I was hoping you could do it for me."

Ethan sighed, knowing that refusing Ava's request would only lead to more nagging and pestering. "Can we do it later? I'm in the middle of something right now."

"No. Our parents are going to be back from grocery shopping any minute, and I need those pictures before they come home."

Ethan sighed again. "Fine, but make it quick."

"Great! It won't take long, and I'll definitely make it up to you!"

"Okay, okay."

Ethan grabbed his camera and followed her begrudgingly. Her light summer dress clung to her figure while she walked in front of him, her curvy hips swaying with each step, capturing his attention.

Ethan felt like a creep for staring at his stepsister's ass—no matter how fine it was—so he looked down and noticed Ava was walking barefoot. The soft pads of her toes barely made a sound as she glided across the wooden floor.

A sense of regret was already creeping in as they entered her room. Ava walked over to the bed, which was covered with a pink comforter and fluffy pillows. Ethan noticed that the family pictures Ava kept on the nightstand were missing, and he wondered why she had taken them down.

"Can we start?" Ava asked, breaking Ethan's train of thought.

He nodded and turned on the camera, adjusting the settings to capture the best lighting in the room. "I'm ready."

"Okay," Ava breathed, grabbed the hem of her dress, and pulled it over her head, revealing a sexy lace violet lingerie set underneath.

Ethan's breath caught in his throat as he quickly averted his gaze. "What the hell, Ava?"

"Would you just take the pictures, Ethan?" Her voice was laced with impatience. "Or I might tell your mom about that night you snuck out the window for the party."

Ethan gritted his teeth, shooting a glare at his stepsister. Was she really this mean? He knew her too well—yes, she definitely was.

Ava smirked, enjoying the power she held over Ethan. She struck a pose while standing next to the bed, making sure her juicy bum, clad only in thongs, was prominently displayed.

Ethan reluctantly raised the camera and clicked the shutter, capturing the provocative image.

Ava changed poses, running her fingers through her hair as she leaned forward, her ample breasts almost spilling out of her skimpy bra. Ethan's cock stirred in his jeans, but he quickly reminded himself that Ava was his stepsister, which only helped a little to suppress his desire.

Ava lowered the delicate strap of her lacy bra, revealing a glimpse of her right breast's creamy skin as she slid it down her shoulder, and the cup slipped away. Ethan's gaze followed every movement, his member growing with each second.

Reaching behind her back, Ava unclasped her bra, allowing it to fall to the floor. Ethan's jaw dropped at the sight of her perky breasts, her pink nipples standing erect.

"Earth to Ethan!" Ava giggled. "We don't have all day."

Ethan quickly snapped out of his daze. "Why do you need these pictures?"

"I'm going to sell them on an adult website," Ava explained. "I'm pretty, and why not make some extra cash?"

Ethan thought Ava was beautiful, with her blonde hair cascading down her shoulders and her mesmerizing blue eyes. In fact, he had a little crush on her from the moment he met her and was certain she could make a lot of money by selling her nudes. He'd buy them if she wasn't his stepsister. However, he couldn't help but feel a twinge of concern about the potential dangers of selling such intimate photos online.

"You can't do that. It's not safe and could have serious consequences."

"Oh, please, like anyone would find out. It's just a harmless way to make some easy money."

"But you're not even eighteen yet. It's illegal," Ethan pointed out.

"I turn eighteen next week," Ava replied confidently. "Besides, plenty of my friends do it, and nothing bad happens to them."

Ethan sighed, still unsure about the whole situation but realizing that Ava was determined to go through with it regardless of his concerns.

"Just take the shots," Ava snapped back, frustrated by Ethan's hesitation. "I know what I'm doing. And I'm not taking a barely 17-year-old boy's advice on how to live my life."

They were barely a few months apart in age, but Ava acted as if she were light years ahead in maturity. Ethan couldn't help but feel a pang of hurt at her dismissive words, but he knew that arguing further would only result in Ava telling on him to his mom. He couldn't tell on her, as he would also have to share his own role in the situation. And to admit that he has seen his stepsister topless was a secret he wanted to keep buried.

As he continued to take pictures, Ethan's discomfort and erection grew. Ava was playing with her breasts, squeezing the soft flesh, pinching her nipples, and casting flirtatious glances in Ethan's direction. He knew it was just an act to get the best shots, but he couldn't help getting increasingly aroused.

Ava playfully slid her fingers into the delicate lace of her thongs, teasingly revealing the supple curves of her bottom to Ethan.

She coyly gazed at him over her shoulder. "Make sure you get plenty of shots as I show off my assets."

Ethan's heart raced as his mind filled with conflicting thoughts and desires about his stepsister. He knew that crossing that line would be wrong, but the temptation was becoming unbearable. And the growing bulge in his pants was becoming harder to ignore.

As Ava slowly removed her thongs, Ethan's erection strained against the confines of his jeans. He discreetly adjusted himself, trying to ease the growing discomfort.

The shutter of the camera clicked repeatedly as Ethan captured every sensual movement that Ava effortlessly executed.

After removing the thongs, she turned to face him, her bare pussy glistening in the soft lighting of the room. Ethan's breath caught in his throat at the sight of his stepsister's naked pussy. His hands trembled as he concentrated on capturing Ava's raw allure.

"We need to get some closeups," Ava said as she sat on the bed.

Ethan's heart raced as he moved closer to Ava. With each shutter click, he absorbed every detail of her enticing breasts, imagining how it would feel to suck those hardened peaks. His cock throbbed with need, aching to be inside her.

Ava's eyes locked with his, a mischievous smile playing on her lips as she captured her nipples in between her fingers, pulling them gently.

Ethan cleared his throat and adjusted the settings on his camera, trying to hide the effect Ava was having on him. But she couldn't have missed the bulge in his pants.

"Don't worry, Ethan." Ava giggled. "I find it quite flattering."

Ethan's cheeks flushed a deep shade of red as he struggled to take his mind off thoughts about how it would feel to fuck his stepsister.

He focused on capturing the perfect shot, attempting to distract himself from the hunger that was building within him. Ava continued to tease him, running her fingers down her abdomen and tracing circles around her navel, and his camera tracked her every movement.

"Why don't you come on the bed with me?" Ava purred as she lay down, spreading her legs and exposing her swollen labia. "You'll get better pictures from this angle," she suggested.

Ethan took a deep breath as he got on the bed and positioned himself in between her legs to capture the desired shot.

As Ethan adjusted his camera settings, precum leaked from the tip of his painfully hard member, visibly staining his pants. Ava smirked, noticing his arousal, and considered exploiting the situation even further.

Despite being a constant nuisance to her, her younger stepbrother had some endearing qualities. He was undeniably attractive, with his dark raven hair, striking gray eyes, and athletic build. But for now, she needed to focus on getting the best shots possible.

As Ava spread her legs, Ethan captured every second of her delicate labia opening up to the camera lens, just like a rose opens up in the morning sun. The soft folds were heavily coated with her essence oozing from her depths. This photoshoot was turning Ava on just as much as it was turning him on.

Her musky scent engulfed him in a cloud of yearning, lust pulsating through his veins with each click of the camera. Ava couldn't help but notice the intensity in Ethan's gaze as he captured her most intimate parts, and she was curious about his reaction if she pushed the boundaries even further.

Her hand trembled slightly as her fingers ran over her freshly shaved mound and across her pulsating bud before dipping into her wetness. Ethan gasped as he watched his stepsister finger herself in front of him. He couldn't help but wish his cock had taken the place of the two fingers that slid in and out of her tight cunt.

Ava spread her labia with her fingers, allowing Ethan a glimpse into her fiery core. His mouth watered and he could barely breathe as he zoomed in on her dripping entrance, capturing every detail of her arousal. His desire became almost unbearable as he longed to taste his stepsister's sweet essence and feel her tightness around him.

"You really like what you see, don't you?" Ava teased, pushing his buttons.

Ethan swallowed hard but remained silent, focusing on getting a good shot of how her juices flowed down her perineum, pooling around her rosebud, and creating a small puddle on the sheets beneath her.

"I think we have enough pictures," Ava said, snatching the camera from Ethan's grasp and placing it on the nightstand.

Locking eyes with Ethan, she slowly crawled towards him, her movements confident. Ethan just sat there, frozen.

Without breaking their intense gaze, Ava whispered, "Let me show you how much I appreciate your help."

She reached for the zipper of his pants, dragging it down while maintaining eye contact. As the zipper slid down, Ethan snapped out of the spell Ava put on him and grabbed her wrists.

"This is wrong, Ava!"

"Sometimes the wrong things feel so good," Ava replied, grinning.

"But you're my stepsister!"

"Yes, I am," she purred, leaning in, her breath caressing his lips. "But I'm not your actual sister."

Ethan felt a rush of conflicting emotions. "We can't do this, Ava," he said, his voice cracking with desire. "It's too risky and complicated."

"Relax, Ethan. It will be our little secret," Ava whispered, leaning in.
