Ava's lips hovered just inches away from Ethan's, tempting him with the promise of forbidden pleasure. His hands clutched her wrists as he struggled to resist the temptation.

As Ava sensuously ran her tongue along the plump curve of her bottom lip, she moaned softly, and Ethan tensed, barely holding back from kissing his stepsister.

The room seemed to grow smaller as Ava moved closer, her breath mingling with Ethan's. He felt his pulse throbbing in his lips, and his cock twitched with each beat of his heart. His mind raced, torn between the desire to succumb to Ava's alluring lips and the fear of crossing a line that should never be crossed.

"You want me," Ava stated.

Ethan clenched his jaw and took a deep breath. "Yes," he whispered.

Ava pressed her naked body against Ethan's, her lips brushing lightly against his, erasing all rational thought from his mind. He kissed her back with a hunger that had been building ever since they first met. Even though they didn't always get along, Ethan couldn't deny the strong attraction he felt towards his stepsister.

Ava's tongue slipped into his mouth, and he lost himself in the intoxicating taste of her. Kissing Ava was like mint chocolate melting on his tongue—a sinful indulgence that he didn't want to resist anymore.

Ava freed her wrists from his grasp and gently pushed Ethan to lie down on the bed. Biting her lip, she hooked her fingers into the waistband of his pants, teasingly tugging them down.

"Wait," Ethan gasped.

"Come on!" Ava whined. "I didn't have sex in a week. I need some cock!"

Ethan's blush deepened into a deep shade of crimson as he struggled to find the right words. "I... I want this too, Ava."

"So, what's the problem?" The impatience in Ava's voice was clear.

Ethan took a deep breath, trying to steady his racing heart. "I just... I never..." His voice trailed off, his words hanging in the air.

"You never had a girl blow you?" Ava asked, her voice laced with surprise.

"No. I mean, yes. Yes, I have," Ethan stammered, his face turning even redder.

It happened last summer during iD Tech camp. A bunch of kids got drunk and played truth or dare, one of which was for Ethan to get a blowjob from a girl he barely knew.

"But... I've never had... erm..."

Ava's jaw dropped in realization. Sure, her stepbrother was a geek, but she never expected him to be so inexperienced. "You're a virgin?"

Ethan wished he would have just kept his mouth shut as Ava's shocked expression intensified. But then she would have figured it out, and it would be even more embarrassing if he came the moment he thrust into her. Just like it happened when that girl was blowing him. He couldn't forget how she had teased him about it afterwards, laughing with her friends.

Ava was a cheerleader and the most popular girl in school. All the football players bragged about how good she was in bed, and Ethan felt like a complete loser in comparison.

Ava smiled. It was a mischievous smile rather than one of mockery. "It's okay, Ethan. I think it's kinda hot that my pussy will be your first."

Ethan felt a bit relieved but also grateful that he masturbated two times in the morning, hoping he could last longer this time.

Ava tugged on his boxers, and he lifted his hips to help her slide them off. Ever since Ava walked in on Ethan while he was showering and caught a glimpse of his enormous cock, she longed to fulfill her curiosity about how it would feel inside of her. A wide smile spread across her face at the sight of his engorged member.

"It looks like you're ready for some fun," she giggled.

Ethan's heartbeat echoed in his ears, matching the pulsing between his legs, as Ava leaned in, her breath hot against the sensitive head. Her eyes met his as she licked her lips and smiled seductively. She wrapped her hand around his shaft and began slowly stroking him, feeling his hardness grow in her palm.

Drops of precum glistened at the tip, lubricating her touch. Ethan's breathing became shallow as he watched his stepsister's hand move up and down his length. Keeping his gaze locked with hers, Ava stuck out her tongue and lightly traced circles around the delicate head, licking up the precum that had gathered there.

"Mmmm," Ava moaned as she sucked his bulbous head into her mouth, her lips tightly sealing around him.

"Oh, fuck," Ethan grunted at the sight of his cock disappearing into his stepsister's warm, wet mouth.

"You like that, huh?"

"Yes," Ethan breathed, captivated by the way Ava slurped up and down his shaft, her tongue swirling and flicking against him.

Her moans vibrated against his length as she took him deeper with each bob of her head. As the tip of his cock hit the back of her throat, Ethan's hips involuntarily bucked forward, and Ava gagged slightly. She quickly adjusted her position, relaxing her throat muscles to take more of him in, eager to show off her skills.

Ethan watched with hungry eyes as her saliva generously dripped down the length of him, pooling at the base and dribbling down his balls. The tightness of his stepsister's throat nearly caused him to erupt. He struggled to maintain control, his breaths coming in ragged gasps.

As she gulped him down, Ava's nose buried in his pubic hair, and she held the position. Tears pooled in the corners of her eyes as she fought back her gag reflex while her stepbrother's cock throbbed in her throat.

Finally, her gag reflex kicked in, and she pulled back slightly, catching her breath. Despite the slight discomfort, Ava continued to bob her head up and down, driving him wild with need.

His body tensed, and Ethan could barely resist the urge to cum into his stepsister's mouth. With each thrust, Ava's mouth seemed to tighten around him as she sucked him like her stepbrother's dick was the most delicious candy she had ever tasted. His balls tightened, aching for a release as he was approaching the point of no return.

The intense sensation of being fully engulfed by Ava's mouth, combined with the sound of her muffled moans, sent Ethan spiraling into a state of lustful ecstasy. He gripped the bed's edge, his body trembling as he shot streams of hot sperm down his stepsister's throat.

Ava swallowed every drop and continued to hold her position as she felt him slowly relax. As she released him from her mouth, Ava looked up at him with a mischievous smile, her eyes filled with satisfaction.

"Fuck, Ava! That was mind-blowing!"

Ava chuckled softly. "I aim to please," she replied playfully as she pulled away.

She backed away and lay on her back, her legs spread wide. "Your turn."

Ethan felt a flutter of nerves and anticipation as he looked into Ava's eyes. He had never pleasured a woman before, but he was eager to learn and make his stepsister feel as good as she had made him feel.

Taking a deep breath, he moved in between Ava's legs, his hands trembling slightly. Ava grabbed his head, her fingers tangling in his hair, as she held his gaze.

"Listen closely, Ethan," she whispered. "I want you to lick me like I am your favorite ice cream, with long, wide licks. As I start to melt, you should lick me faster and harder. And you won't stop until you make me scream. Understood?"

Ethan nodded, flushed with anticipation. Ava pushed his head down, guiding him to where she wanted him. Her musky scent, mingled with sweat, drove Ethan wild with desire, and he couldn't wait to taste her.

As Ethan traced his tongue along Ava's delicate folds, he was overcome by her sweet taste and the scent of her arousal. The soft moans from Ava's lips encouraged him to keep going. She arched her back and pressed herself against his eager mouth, her hands gripping his hair.

His stepsister's pussy tasted like an addictive nectar, and Ethan feasted on her with an insatiable hunger. His cock throbbed with excitement, and he couldn't help but imagine how incredible it would feel to be inside her.

He continued to explore her with his tongue, switching between gentle licks and firmer strokes. Ava controlled his movements by subtly shifting her hips and guiding his head with her hands to maximize her pleasure. Ethan eagerly followed her lead, his tongue darting and swirling, lapping up every drop of her essence.

"Yes, Ethan," she gasped. "Just like that. Fuck me with your tongue."

With each breathy moan, Ethan felt a surge of courage. His tongue dove deeper and deeper into her warm hole, circling around to explore every inch of her satin flesh.

Ava could feel his excitement, his eagerness to please. It fueled her desire even more. Her thighs shivered as she pressed them against his head, her whimpers growing louder and more urgent.

"Put two fingers inside me, Ethan." Ava's voice was a husky whisper. "Make me cum."

Ethan pulled his tongue away, his lips glistening with her arousal as he eagerly complied with her request. Watching her closely, he inserted two fingers into her wetness, feeling her walls clench around them. Ava's face contorted in pleasure as she let out a guttural moan, her body arching off the bed, urging him on to push deeper.

"Lick my clit while you finger me." Her voice was heavy with desire.

His tongue pressed against her swollen nub as his fingers continued to pump in and out of her. She writhed beneath him, crying out with each flick of his tongue and thrust of his fingers.

"That's it! Don't stop!"

As if Ethan would ever even consider stopping. The taste and feel of his stepsister's cunt completely enthralled him, and he wanted more. His cock stiffened, aching to be inside her.

Ava's hips bucked uncontrollably as waves of pleasure washed over her. He felt the slick heat of her core convulsing against his fingers as her orgasm crashed through her body, causing her to shudder and gasp for breath. He continued to suckle and lick her sensitive bud as his fingers continued their relentless rhythm inside her.

"Mmm... Fuck..." Ava groaned in ecstasy, her body shaking with the intensity of her orgasm.

Her juices gushed from her, coating his fingers and pouring onto the sheets below. Ethan tried his hardest to gobble up every drop, but squirts of her nectar escaped his grasp, leaving a wet mess on the bed.

As she came down from her climax, Ava pulled Ethan up to her, their lips crashing together in a passionate kiss. The taste of her own essence lingered on her tongue, fueling her desire for more.

"Good boy," she whispered against his lips. "That was a great start. But there's so much more we can explore together."

She pulled up his T-shirt and ran her hands over his bare chest, pushing him to lie back on the bed. Ethan's breath hitched as his stepsister straddled him, her fierce gaze full of lustful intent.

Ava could almost taste his anticipation. Being in control and taking his innocence, it all aroused her beyond measure.

Ethan's body shivered with desire as her nails traced teasingly across his chest, leaving a trail of fiery heat in their wake. Her delicate fingers moved down his toned abdomen, making him shudder with pleasure.

She boldly descended until she reached the soft curls at his groin, sparking an inferno within him. Then she grabbed his throbbing cock and leaned down. "Let me show you how good it feels."

"But, erm... Condoms?"

Ava's sexy giggle echoed through the room. "I'm on the pill. I want to feel every inch of your hard cock, skin on skin. Aren't you dying to experience how wet and ready my pussy is just for you?"

Ethan nodded, and Ava positioned herself above him, her eyes locked with his. With a throaty moan, she slowly lowered herself onto his hardness, taking him inch by inch. Ethan gasped, his hands gripping her hips as he felt his erection slide into his stepsister's damp warmth until he was fully engulfed.

Ava reveled in her dominance over him, gasping as his throbbing shaft invaded her tightness, filling her to the brim and deliciously stretching her. She began to move, her hips undulating in a rhythm that was both sensual and demanding.

Ava set the pace, her body taking control as she rode him with an intensity that left Ethan breathless. He watched in awe as her voluptuous frame gyrated above him, each curve enchanting him with every powerful thrust.

"Fuck, Ava," Ethan groaned. "You feel so good."

Ava's lips curled into a satisfied smile as she continued to ride him, her movements becoming more desperate. His cock hardened even more, pulsating with lust. Ethan's fingers dug into the supple flesh of her hips as he mimicked her rhythm, desperate to keep up with Ava's intense passion.

She moved wildly, savoring the forbidden sensation of her stepbrother's hard cock buried deep within her. Their bodies created an intoxicating rhythm that filled the room with erotic moans and a provocative sound of their of flesh slapping together. The aroma of sex hung heavy in the air, mingling with their sweat and labored breathing.

Ethan completely surrendered himself, allowing Ava to lead him deeper into ecstasy. With every thrust, he felt the need building to an unbearable level. Ava sensed his impending climax and increased her pace, bringing him closer to the edge.

"Fuck me, Ethan," she wailed, rubbing her swollen bud against his pubic bone. "Fill me with your cum."

Finally, unable to hold back any longer, Ethan exploded with a powerful release, his body trembling with the force of his orgasm as his seed spilled deep into his stepsister's welcoming, tight depths.

The sensation of his hot sperm squirting inside her pushed Ava over the edge, her own orgasm crashing down like a tidal wave, her walls gripping his pulsing length with a force that made them both cry out. Ava continued to move, milking her stepbrother's cock for every last drop of pleasure.

As they both caught their breath, Ava collapsed beside Ethan, her body glistening with sweat. She turned to him, a satisfied smile playing on her lips. "See, Ethan? Sometimes, the wrong can feel so damn right."

Ethan nodded, a satisfied smile playing on his lips. "You're right, Ava. That was... amazing."

The front door creaked open, startling both Ethan and Ava. Ethan quickly got up, dressed, and dashed for the door.

"See you at lunch," Ava whispered.

Ethan nodded and quietly slipped out of her room, leaving his camera behind. Ava picked it up and put it in the drawer, then got up from the bed. Ethan's lustful essence poured from her core as she sauntered towards the bookshelf strategically placed in front of her bed.

She smiled at the red light indicating that the camera, cleverly hidden among the cluttered objects, was recording. Then, in one swift motion, she turned it off.

Ava taped every intimate moment between her and Ethan. She knew she could use this footage to manipulate him, blackmail him, or simply keep it as a reminder of the day she took her stepbrother's virginity.

His milky white fluid continued to gush from her pussy, now trickling down her inner thighs, which she quickly whipped with her fingers. As she licked her cum-coated fingers, Ava heard her stepmother's voice calling from downstairs.

"Ethan! Ava! Can you come down, please?"

Ava could hear the thud of Ethan's hurried footsteps in the hallway as he rushed to respond.

"Coming!" she called back, smiling naughtily.

After quickly slipping into her summer dress, skipping the underwear to tease Ethan, Ava walked down to the kitchen to find her family waiting for her.

As soon as she walked into the kitchen, Ethan's gaze fell on her. The way her dress clung to her curves and her nipples poked through the fabric made him flush a deep red. Ava couldn't help but feel smug about his reaction.

Their parents were standing at the kitchen counter, and Ethan was perched on a bar stool across from them. Ava took the seat next to him, intentionally brushing up against him. She looked around and noticed that no food was being prepared.

"I thought we were having lunch?" Ava asked, her eyes playfully meeting Ethan's. "I only had a small snack earlier, and I'm really hungry now."

Ethan, trying to maintain his composure in front of their parents, coughed awkwardly and avoided her gaze.

"We're actually going out for lunch," Ethan's mom announced. "But before that, we have some news to share."

Ava remembered the last time they had a family meeting like this—it was when they announced their marriage plans. She sighed and turned to face their parents.

"So, what's the news?" Ava asked, her voice tinged with impatience.

The air in the kitchen grew heavy with tension as Ethan's mom continued. "This morning, we received a letter that made us realize we couldn't keep this secret any longer. We didn't actually go out to buy groceries; we needed time to figure out how to tell you."

Her gaze locked with Ava's. "Your father and I," she began, her voice faltering slightly, "were involved with each other while still married to your parents."

Ethan's reaction was immediate and visceral. "You cheated on dad?!"

Ava sat there, her eyes wide as the truth sank in. A whirlwind of thoughts raced through her mind. Why now? What prompted them to reveal such a shattering secret after all this time?

Ethan's mom's voice was a mere whisper. "I'm sorry, honey," she said, her eyes searching Ethan's for understanding. "We never intended to hurt you. It was wrong, but our love for each other was undeniable, and we believe it's important to be honest with you now."

Before the silence could settle in, Ava's dad spoke up, his voice unsteady with emotion. "We took a DNA test," he said, a tremor in his voice betraying the gravity of his next words. "And the results confirmed something unexpected. Ethan, you are my son."

Ethan was left speechless by the stunning revelation, which turned his world upside down in an instant.

"Fuck, " Ava whispered under her breath, still feeling her brother's—not just her stepbrother's—seed seeping from deep...
