Chapter 9 - The Cousin

Viet's presence in our lives grew inescapable, like a permanent fixture.

At first, it was the three of us - Hoa, Viet, and me, occasionally going to movies or bars together. Now, they were going out alone. Hoa signed up for a gym class with Viet, and every afternoon, he'd pick her up for workouts.

Seeing her in tight gym clothes sent wild images flashing through my mind. Would they hook up in the locker room, the showers, or some park?

My suspicions seemed confirmed each night when Hoa returned with vivid hickeys on her neck she didn't bother hiding. I stood there, hands trembling, catching a whiff of another man's scent on my wife body, my heart pounding with jealousy and a burning thrill. My parents sometimes noticed her leaving with the neighbor, but after dropping hints and seeing my apparent acceptance, they stopped commenting.

With Hoa out more, we hired a daytime maid to babysit our son. Recent stories of maids abusing kids made me uneasy about leaving our son with a stranger. On a colleague's advice, I secretly installed four cameras at home, in my living room, kitchen, our bedroom, and the spare room, for peace of mind.

Today, a new member joined our household. It's Duc, my cousin, son of my second uncle and aunt (you may recall him from Chapter 5). Seeing him stirred memories of Hieu and that day he **** my dad to eat a sponge cake laced with his semen.

That day, my grandparents and uncle's family visited, Duc included. While he played games in my room, Hieu was "playing" with my mom and aunt next door. I don't know what Hieu said to him, but Duc calmly watched his own mother being taken by another boy.

Now Duc was sent to stay with us temporarily, as his parents requested. My parents happily agreed. Another man or rather, a hormone-charged man entered our home. I felt uneasy about Duc, especially since he knew about Mom and Hieu, but I didn't dare object, fearing I'd seem selfish. Besides, my mind was consumed with Hoa and Viet.

Duc moved into the spare room. Tall and handsome, thanks to good genes, he had a noticeable bulge in his shorts as he strutted around. I wondered if he dressed that way on purpose. I often caught him in tight tank tops, his muscles and prominent crotch impossible to ignore when he lounged on the sofa. His image triggered a memory of him ejaculating into my face towel. He must have girls swooning over him.

Even my sister Tam adored him. My parents asked Duc to tutor her whenever he was free, since she was preparing for her college entrance exam. Though Tam had just turned 18, she still had that innocent, trusting nature that often surprised people. She quickly grew attached to our new cousin, always asking him for help with homework or chatting excitedly about movies and music. She called him “Brother Duc” in the sweetest voice and even saved her favorite snacks for him, something she never did for me, even after all the years I’d spoiled her.

Duc took it all in stride, likely used to being spoiled as an only child. Sometimes, he even ordered me around. I felt intimidated by tall, muscular guys like Duc, Viet, or Hieu, maybe inherited from my Dad, who seemed cowed by them too. I recalled Dad eating Hieu's semen as a high schooler. I don't know how he felt, but when Duc bossed me around, I felt a mix of resentment and strange excitement.

Sensing Dad's and my weakness, Duc grew bolder, sometimes treating Dad like a servant.

Today was Saturday, but I had to work overtime. Bored, I remembered my parents were at a wedding, Hoa was likely shopping with Viet, and I wondered about our son. So I opened my laptop to check the home cameras. The maid was putting Bi our son to sleep in our bedroom. As I watched, movement caught my eye on another feed. It's the camera in Duc's room.

He was home, lounging on his bed in just athletic shorts, one hand scrolling his phone, the other inside his crotch. I smirked. He's probably watching porn and jerking off. Feeling weird spying on a guy masturbating, I was about to close the feed when a knock sounded.

• "Brother Duc! Are you busy? Please help me with this problem!"

My heart skipped. It was my sister's voice. Duc flinched, pulling his hand from his shorts. He paused, then grinned slyly. "I'm here!"

He stood, shirtless, and opened the door. Tam appeared on the screen, her face innocent and cheerful, unfazed by his half-naked state. She probably didn't think twice about it.

Duc sat at the desk and patted his lap. “Come here, sit with me. It’ll be easier to explain.”

Tam hesitated, cheeks flushing. “But…”

• “Come on,” Duc said with a warm, coaxing smile. “There’s nothing wrong with a little sister sitting on her big brother’s lap, right?”

She bit her lip, gave a small nod, and carefully settled onto his thighs. A quiet, satisfied smirk crossed Duc’s face as he wrapped one arm loosely around her waist to “steady” her. He began explaining the problem, his voice calm and patient, but his free hand soon drifted to her bare thigh, brushing it lightly as if by accident.

Tam didn’t seem to notice at first, her eyes fixed on the notebook. Encouraged, Duc let his palm rest fully on her smooth skin, fingers tracing slow, gentle circles. Gradually, he slid higher, inch by inch, until his fingertips grazed the edge of her shorts.

From the camera feed, I saw her shiver. Duc felt it too. He quickly distracted her.

• “Hey, you used the wrong formula here! Look.”

As Tam leaned forward to check, his hand moved again. This time his fingers settled between her legs, pressing lightly over the thin fabric, stroking up and down along her slit in slow, deliberate motions.

Tam shifted uncomfortably in his lap.

• “Something wrong?” he asked innocently.
• “Um… something in your shorts keeps poking my butt,” she whispered, embarrassed.

Duc chuckled softly. “Ah, I see. Let’s fix that so we’re both comfortable.”

Before she could react, he asked her to stand for a moment. While her back was turned, he quickly pushed down his shorts and boxers, freeing his thick, hardening cock. Then, in one swift motion, he hooked his fingers into the waistband of her shorts and panties and tugged them down to her knees.

Tam let out a startled squeak, hands flying to cover herself. “Ah!”

• “Shh, it’s okay,” he soothed, guiding her back onto his lap. “It’ll feel much better without all that fabric in the way. Brothers and sisters see each other naked all the time. It’s no big deal.”

Still flushed and uncertain, Tam let him pull her down. As she settled, her eyes widened. Between her thighs, Duc’s long, thick shaft now pressed firmly upward, nestled snugly along her bare pussy, the swollen head peeking out in front.

• “W-what is that…?” she breathed.
• “That’s the thing that was poking you,” Duc replied casually, as if it were the most normal explanation. “It’s fine to leave it there, right? It keeps you steady and feels way more comfortable than before.”

Tam squirmed slightly, but the warm, hard pressure against her most sensitive spot did feel… different. Strangely nice. She nodded shyly and tried to focus on the homework again.

A minute later, Duc began to rock his hips in slow, subtle circles, barely noticeable at first. His rigid cock glided smoothly up and down her slick folds, coating itself in her growing wetness. Tam’s breathing grew shallow, her grip tightening on the pencil, but she stayed quiet, caught between confusion and an unfamiliar, tingling warmth spreading through her body.

After a while, Tam finally finished her homework and snapped the notebook shut with a satisfied sigh.

Duc’s face flashed a flicker of disappointment. He clearly didn’t want the moment to end, but he had no excuse to keep her there. Reluctantly, he let her stand, watching as she quickly tugged her shorts and panties back up.

As she stood to leave, I sighed in relief, though a twisted part of me felt disappointed.

Just as she turned to leave, Tam paused, snatched a comic book from the desk, and flopped belly-down onto his bed.

• "No plans this weekend, Brother Duc?" she asked, kicking her feet playfully in the air.
• "Nah," he replied, his voice low and warm. “I’m staying home to hang out with you. Want to play a game?”

Tam's face lit up. She tossed the comic aside. "Yay! What's the game?"

• "I've got a fun one!"

Her eyes sparkled. "What is it? Tell me!"

• "It's called Blindfold Guess. Simple rules: I blindfold you, give you an object to taste, just using your tongue, no hands allowed, and you have to name it."

Tam pouted. "Sounds boring."

• "If you guess right, and I'll take you for ice cream this afternoon."

Her favorite treat perked her up. "Okay, let's play! What if I guess wrong?"

• “You get as many tries as you need. If you still can’t figure it out in fifteen minutes…” He paused for effect. “I get to spank you.”

Tam blushed. "You're so mean!"

• “Hey, fair’s fair. Play to win, take the penalty if you lose. Want that ice cream or not? It’s easy. One right guess and it’s yours.”
• "Promise?"
• "Promise"

She squeezed her eyes shut, excited. Đức grabbed the cloth face mask hanging on the wall and tied it snugly over her eyes.

• “No peeking,” he warned, voice dropping lower. “Or I won’t play with you anymore.”

Tam nodded eagerly, trusting as ever.

A wicked smirk spread across Duc’s face. He gripped his thick, already-hard cock, still slick from earlier, and stepped closer until it hovered inches from her face.

• “First, sniff it and guess.”

He brushed the swollen head lightly across her nose. Tâm inhaled, nose wrinkling. “Ew, what’s that smell? Like… a rubber eraser?”

• “Nope,” he chuckled, voice husky. “Now lick it and try again.”

Tam hesitated for a second, then darted her tongue out for a tentative lick. A jolt of pleasure shot through Duc; he bit his lip to stifle a groan, eyes hooded with satisfaction. Quietly, he lifted his phone and started recording.

She licked again, frowning in concentration. “Your hand? Wait… no, your elbow?”

• "Wrong again!" he said, amusement thick in his tone. “Open wide. I’m putting it in your mouth now. Suck it like an ice cream. No teeth, just use your lips and tongue.”

Before she could protest, he added, "Last chance. You’ve got five minutes to suck and guess!"

Tam, still dreaming of ice cream, parted her lips obediently. Her innocent mind was clouded by the treat. She opened her mouth. Duc slowly slid his veiny cock in. My heart raced like it would burst.

Watching Duc's chiseled hips thrust into my sister's small mouth made me want to explode. A perverse thrill overpowered my reason. Instead of rushing home to stop it, I pulled out my own pathetic cock and started jerking off. Luckily, I was alone in the office. I hadn't felt this aroused in ages.

On the screen, Duc tilted his head back, savoring Tam's warm mouth. He grabbed her head, thrusting his thick cock deeper. Tam, like an obedient kitten, sucked eagerly, drool dripping down her chin, oblivious to what she was doing.

Minutes passed. Tam pushed him back, gasping. "God, what was that? I almost choked! I can't guess it! I give up!" She reached for the mask, but Duc stopped her.

• "No peeking! You still get a penalty!"
• "Penalty with the blindfold on?" Tam pouted.
• "Yup! But since you tried hard, I'll still take you for ice cream."

Her face brightened.

• "But a penalty's a penalty. This stays our secret, okay? If you tell anyone, we're done playing."
• "Got it!" Tam huffed, lying face-down on the bed. "Go ahead, punish me!"

Duc swallowed hard, his eyes fixed on the soft, round curve of Tam’s hips as she lay there, blindfolded and trusting. He hooked his fingers into the waistband of her shorts once more and slowly tugged them down, exposing her completely.

Tam gasped, her body tensing. “Brother Duc… what are you doing?”

• “This is your penalty, remember?” he murmured, voice low and soothing. “Just stay still for me. It’ll be over soon.”

He slipped a pillow beneath her stomach, gently lifting her hips until her bottom arched invitingly toward him. For a long moment, he simply admired her. The smooth skin, the delicate swell of her cheeks, the faint dusting of soft hair between her thighs. His hands finally moved, palms gliding over her flesh, squeezing gently. A tiny, involuntary moan escaped Tam’s lips before she caught herself and went quiet.

Emboldened by her reaction, Duc let his fingers trail lower, brushing the warm, untouched mound between her legs. He traced her slit lightly at first, feeling the slick heat already gathering there.

Tam jolted, her back arching sharply. “Brother Duc… I… I think I wet myself…” she whispered, voice trembling with confusion and embarrassment.

Duc brought his glistening fingers to his lips, tasting her sweetness with a slow smile. “That’s not pee, little sister,” he said softly. “That means you’re ready… and you’ve been very naughty. Time for a proper punishment.”

He positioned himself behind her, knees bracketing her thighs. His thick, throbbing cock, already slick from her earlier unwitting attention, rested heavily against her entrance. He rubbed the swollen head up and down her folds, coating himself in her wetness, teasing her until soft whimpers spilled from her lips.

• “Please… it feels strange…” Tam begged quietly, squirming.
• “Shh, it’s okay,” Duc whispered, leaning over her, one hand stroking her back in slow, calming circles. “I’ll go slow. Just breathe for me.”

With infinite patience, he pressed forward. The broad head parted her tight, virgin entrance, stretching her little by little. Tam’s breath hitched; her fingers clutched the sheets as a sharp sting bloomed inside her.

• “It hurts…” she whimpered, voice cracking, tears welling beneath the blindfold.

Duc froze immediately, buried only an inch or two inside her incredible warmth. “I’ve got you,” he soothed, kissing the nape of her neck tenderly. “Relax, good girl. The pain will fade real quick. I promise.”

He stayed perfectly still, letting her body adjust, continuing to stroke her back, her sides, murmuring soft praises. “You’re doing so well… so tight…”

Gradually, the burning eased. Tam’s tense muscles softened around him; her whimpers turned into shaky breaths. Only when he felt her hips give the tiniest rock backward did he dare move again. Slow, gentle thrusts, sinking deeper by careful degrees until, with a shared gasp, he was fully seated inside her.

Tam’s mouth fell open in a silent cry, half surprise, half wonder, as the pain dissolved into a strange, blooming fullness that sent sparks through her untouched body.

Duc groaned low in his throat, savoring the impossible heat gripping him. “There we go… good girl,” he praised, beginning a slow, steady rhythm. Each gentle thrust stroked new places inside her, coaxing soft, wondering moans from her lips.

He reached beneath her, fingers finding the sensitive pearl at the top of her slit, circling it in time with his movements. Tam’s breathing grew ragged; her hips began to move instinctively, meeting him halfway. The blindfold kept her in darkness, heightening every sensation until pleasure overtook everything else.

Only when her body trembled on the edge did Duc flip her gently onto her back. Still blindfolded, she looked beautifully lost. Lips parted, cheeks flushed, small breasts rising and falling rapidly. He spread her legs wide, settling between them, and slid back inside with one smooth stroke.

Tam cried out softly, arms wrapping around his neck as if anchoring herself. Duc kissed her tears away, moving deeper, faster, drawing out every sweet sound until her young body arched beneath him in her very first climax.

As she clenched around him in helpless waves, Duc buried himself to the hilt and let go, flooding her with long, pulsing jets of heat. I just witnessed my cousin cum inside my sister in our own house. From the camera, I watched my little sister’s innocence melting into ecstasy and came harder than ever, shame and arousal twisting together in a way I could no longer untangle.

On the screen, Duc held my sister close through the aftershocks, whispering soft comforts until her breathing evened out. I panicked, wondering if my sister could get pregnant. I considered rushing home with a morning-after pill, but the depraved part of me won. I didn't want to end these twisted thrills. I closed the laptop, pretending nothing happened.

After witnessing Duc seduce Tam into adult games, the depraved beast in me fully awoke. It was like reliving the days when Hieu toyed with our family like slaves, satisfying his lust. I'd watched my mom, wife, and now sister fall under other men's control. My weak resistance was gone.

I bought two more cameras, secretly installing them in my parents' and Tam's rooms.

Through them, I saw Duc repeatedly lure Tam into "Blindfold Guess," spanking her for wrong answers, in his room, hers, or even upstairs while the family was in the living room.

My sister, naively, became my cousin's cum receptacle. With her, he no longer needed to jerk off or chase girls. She grew accustomed to "spankings" after study sessions, even seeking him out to play. Seeing her hooked, Duc escalated.

One day, after tutoring, he suggested a game. As Tam eagerly sucked his erect cock, he stopped her. "Tam, today I'll show you the object you've been guessing!"

She pouted, reluctantly pulling away. "But if I see it, can we still play?"

He smirked. "Of course! I've got even better games. But you swear to keep it secret. No telling anyone!"

• "I promise!"

He gently untied the blindfold and let it fall away.

Tam blinked a few times, adjusting to the light, then her gaze dropped, and widened in recognition. There it was again: the same thick, imposing cock she had first seen that day during tutoring, the one that had secretly filled her thoughts ever since.

A soft flush spread across her cheeks as memories of that first shocking reveal rushed back. The heat, the size, the strange thrill it had sparked in her innocent mind.

Duc watched her reaction with a knowing smile. “Remember him?” he teased quietly. “You’ve been wondering about it all this time, haven’t you?”

Tam bit her lip, too shy to answer, but her eyes stayed fixed on it, curious and mesmerized. Encouraged by his gentle nod, she reached out slowly, fingers brushing the warm, smooth skin. She traced its length with tentative fascination, as if finally allowed to explore the mystery that had quietly enthralled her for weeks.

Leaning closer, she gave a shy, experimental lick along the shaft, tasting it properly for the first time with her eyes open. A small shiver ran through her as the familiar, forbidden pleasure returned, stronger now that she could see exactly what was making her body react this way.

Duc eased back onto the edge of the bed, legs spread wide, his thick cock still glistening from Tam’s earlier attention. He patted the floor in front of him with a lazy, commanding smile.

• “Come here, little sister. Kneel for me.”

Tam obeyed without hesitation, sinking to her knees between his thighs. Her small hands rested lightly on his legs as she leaned forward, lips parting to take him back into the warm, wet heaven of her mouth. She moved slowly at first, savoring the familiar taste, her tongue swirling around the swollen head before sliding deeper.

Duc let out a low, appreciative groan, one hand threading gently through her hair to guide her rhythm. He watched her with hooded eyes, hips rocking just enough to feed her more of his length. The sight of her innocent face stretched around him, cheeks hollowing with every eager suck, sent waves of pleasure coursing through him.

After several long, indulgent minutes, he lifted his hips slightly, pulling free with a soft, wet pop. Tam looked up, confused and a little breathless, lips shiny.

• “Lower,” he murmured, voice rough with desire. He cupped the back of her head and guided her down until her mouth brushed the heavy weight of his balls.

Tam hesitated only a second before understanding. Her tongue darted out, tracing the sensitive skin, then drawing one into her mouth to suck gently. Duc’s head fell back, a deep, guttural moan escaping as his fingers tightened in her hair. Watching through the camera, I felt my pulse thunder in my ears. My little sister, so trusting, worshipping him like this while he basked in pure ecstasy.

Emboldened by his reactions, Duc hooked his legs over her shoulders, lifting his hips higher. The silent command was clear. Tam, ever the obedient one, pressed forward without protest. Her soft tongue traced the forbidden crease, circling and lapping with surprising tenderness. Duc shuddered hard, one hand gripping the sheets as raw, animal groans spilled from his throat.

The room filled with the sounds of his pleasure and her devoted attention until, finally, he couldn’t wait any longer.

With effortless strength, he pulled her up onto the bed, positioning her beneath him. Tam’s breath came in shallow gasps as he settled between her thighs, the thick head of his cock nudging insistently at her slick entrance. One slow, deliberate push, and he sank into her welcoming heat.

He took his time at first, long, deep strokes that made her whimper and clutch at his shoulders. Then faster, harder, flipping her onto her stomach, her side, her back again, claiming every angle, every position, until her young body trembled uncontrollably beneath him.

Tam’s moans grew louder, more ****, her nails digging into his back as waves of pleasure consumed her innocent features. Eyes glazed, lips parted, she surrendered completely.

With a final, possessive thrust, Duc buried himself to the hilt and let go, flooding her smooth, tight pussy with thick, pulsing ropes of cum. Tam cried out softly, clinging to him as the warmth spread deep inside her, her own climax crashing over her in helpless, shuddering bliss.

From then on, my sister became my cousin's sex toy, used whenever and wherever he wanted. His contempt for my Dad and me grew. I caught him on camera making Tam service him behind Dad's back as he read the newspaper in the kitchen. Near climax, he pushed her aside, shooting thick cum into the coffee milk Tam was preparing for Dad.

I shuddered as Dad stirred the coffee and drank it, oblivious, under Duc's smug smirk. How would he feel knowing Duc's semen was in his drink? But I reasoned he'd eaten Hieu's cum before. What's a bit more from Duc?

I thought those were the wildest moments in Duc's depraved game. But the madness was just beginning.

On the camera, I saw three boys waiting outside our house. My parents were at a distant relative's event, and Hoa had taken Bi to her parents'. Only Tam, studying in her room, and Duc, opening the door, were home. I assumed he'd invited friends to study.

Duc led them upstairs to Tam's room, barging in. She looked up, startled.

• "Done with homework, Tam? I brought friends over. Wanna play with us?" He gestured his friends inside, grinning at her.

Tam, excited by his invitation, closed her notebook. "Yeah! What game?"

• "Your best one: Blindfold Guess!"
• "But I already know what it is! No need to guess!" she said innocently.
• "Hehe, come here. It's a bit different this time." He introduced his friends: Dung, Quan, and Dat. "We'll stand in a circle, you're blindfolded in the middle. Sniff and suck each of us, then guess who's who. Guess right, we'll take you out and buy ice cream. Guess wrong, you get punished!"

Duc and his friends laughed as he blindfolded Tam. She knelt obediently, mouth open like a trained puppy. The four boys' bulges strained as they watched. One by one, they stripped, their erect cocks springing free. Seeing their thick, veiny members, I worried for my sister.

Dung went first, sliding his cock into her mouth. Tam, like a practiced whore, licked the tip, shaft, and sucked his balls, making him grunt. She took him deep, sucking eagerly until he stopped her, likely to avoid cumming.

Quan took over, more aggressive. He grabbed her head, thrusting hard, hitting her throat. Sometimes he held her against his crotch, buried deep, until she choked, then released her, coughing.

Dat was gentler, having her lick his groin and ass. Familiar with servicing Duc, Tam complied, making Dat moan. Finally, Duc took his turn.

After Tam serviced all four, Duc removed her blindfold and asked which was him. She thought, then said, "You were the last."

The others glanced at Duc, surprised she got it right. No wonder. Her daily sessions with him made his cock and scent familiar.

• "Wrong!" Duc lied. "I was first!"

Tam looked shocked but didn't argue.

• "You know the penalty!" he laughed.

Tam climbed onto the bed with a shy but obedient smile, settling onto her back and slowly parting her thighs. Her smooth, pink pussy came into full view, exposed to the hungry eyes of the four boys. The air thickened with their heavy breathing.

The three friends swallowed hard, their cocks straining as they stared. Duc, lounging against the headboard with a smug grin, waved them forward. “Go ahead, guys. I’ve had my fill of her for now. She’s all yours.”

Dung went first, crawling between her legs with trembling eagerness. He rubbed the head of his cock along her slick folds a few times, savoring her soft whimpers, then pushed in slowly. Tam’s breath hitched as he filled her, her small body arching beneath his youthful, relentless thrusts. He took her missionary at first. Deep, steady strokes that made her toes curl. Then flipping her onto her hands and knees, pounding harder until he groaned and spilled inside her with shuddering pulses.

Quan was next, rougher and impatient. He pulled her on top of him, guiding her down onto his length in one firm motion. Tam gasped, steadying herself on his chest as he gripped her hips and bounced her up and down. When he grew close, he rolled her beneath him, hooking her legs over his shoulders and driving deep until he came with a guttural moan, adding his load to the warmth already inside her.

Dat took his time, savoring every moment. He laid her on her side, spooning behind her, one hand teasing her small breasts while he slid in slowly from behind. His thrusts were long and deliberate, drawing soft, breathless cries from Tam as he kissed her neck and whispered praise. He pulled out and asked my sister to lick his cock, then sliding back in to release deep inside her.

Finally, Duc claimed his turn, flipping her onto her stomach and taking her with the confident ease of ownership. His rhythm was perfect, slow builds followed by hard, possessive thrusts that left Tam trembling and clinging to the sheets. When he came, he buried himself fully, flooding her one last time with a low, satisfied growl.

When it was over, Tam lay sprawled across the rumpled sheets, utterly spent. Her chest rose and fell in shallow breaths, marked with faint red welts from eager hands and mouths. Between her trembling thighs, thick streams of cum leaked from her swollen, well-used pussy, pooling beneath her.

Watching that creamy white mess slowly drip from my little sister, the truth hit me like a punch to the gut: she had become nothing more than a willing, perfect sex toy for Duc and his friends, and I couldn’t look away.
