Chronolust Temptation [18+] High S*xual Content
Ch.5[d] Sister’s Blackmail [oral (facef*cking), vaginal, MF]

The afternoon sun bathed Tokyo in a warm glow as Hayao lingered at the school gates, his mind a tempest of desire and dread. Shigeru’s cryptic offer hung like a dark cloud, its secrecy and sly undertones setting his nerves ablaze. The graduation trip, a rite of passage promising turquoise waves and coral reefs, was slipping through his fingers, the money his mother gave him having been squandered on video games in a reckless spree he now cursed. Nanako’s vibrant chatter about snorkeling had deepened his frustration; her bright smile a stark contrast to his sinking heart. 

Shigeru was probably planning something stupid.

“Nah, man,” Hayao muttered to Shigeru’s retreating figure, his voice tight. “I’ll think of something.” 

Shigeru’s smirk faltered, but he shrugged, leaving Hayao with a gnawing unease. It was probably something perverted, like him getting his mother’s or his sister’s underwear for him. 

Hayao needed another way, and fast. His sister Yumi might have savings from her café job. Asking her would be humiliating, especially with Mai likely to erupt over his financial folly, but it was better than whatever Shigeru would have proposed. With a deep breath, Hayao set off for home, the city’s hum a background noise as his thoughts churned. 

The walk was a blur, Tokyo’s neon signs and crowded sidewalks barely registering. His school uniform chafed, a reminder of the mundane world clashing with the forbidden ecstasy of Mai’s bedroom. The night’s intensity—her breasts around his cock, her moans as he fucked her ass—lingered, making focus difficult. This morning, he’d taken her again, her pussy clenching as she screamed his name, cum painting her thighs. The memory sent a jolt to his groin, but he pushed it aside, quickening his pace to their apartment building. He needed to stay sharp, to navigate Yumi’s teasing and secure the money without revealing too much.

Unlocking the apartment door, Hayao stepped inside, the familiar scent of Mai’s jasmine perfume greeting him, mingling with the earthy aroma of tatami. 

“Mom, I’m home,” he called, but silence answered. 

Mai was out, likely at the gym or shopping, a stroke of luck giving him privacy to approach Yumi. He kicked off his shoes, heart pounding—not just from the stairs but from nerves. Asking his sister for money felt like admitting failure, and Yumi’s sharp wit would make it worse. He rehearsed his plea: “Yumi, I need a loan for the trip. I’ll pay you back.” But he knew she’d probe, demand why he didn’t ask Mai. He had to tread carefully.

Down the hallway, he reached Yumi’s door, its pastel stickers a relic of her high school days. He knocked, knuckles rapping softly. “Yumi, you in there?”

“Yeah, come in,” her voice replied, casual and warm.

Hayao opened the door, stepping into her room, a cozy space cluttered with books, a laptop, and a small vanity. Yumi sat on the edge of her bed, legs crossed, flipping through a fashion magazine. Her short skirt rode up, revealing smooth thighs, and her tight top hugged her large breasts, her long black hair cascading over her shoulders. She looked up, dark eyes meeting his, a playful smile curving her lips. “Hey, little brother. What’s up?” she asked, setting the magazine aside.

Hayao closed the door, throat dry. “I need to ask you something,” he said, shifting uncomfortably.

Yumi’s eyebrow arched, smile widening. “Oh? This sounds serious. Spill it.”

He took a deep breath, forcing the words out. “It’s about the Okinawa trip. I don’t have enough money for it. I was hoping... maybe you could lend me some?”

Yumi’s eyes sparkled with amusement, her smile turning mischievous. “Why not ask Mom? She’s got the cash, right?”

Hayao looked down, cheeks burning. “I can’t. I spent the money she already gave me on games, and if she finds out, she’ll be pissed.”

Yumi burst into laughter, the sound filling the room, her head tilting back. “Oh, Hayao, you’re such a dumbass! Mom’s gonna lose it when she hears you blew the money on games.”

He winced, her teasing hitting home. “That’s why I’m asking you, Yumi. Please, I really want to go. It’s a big deal.”

She stopped laughing, studying him thoughtfully, her gaze sharpening. “Alright, I’ll give you the money,” she said, tone shifting, a darker edge beneath her playfulness. “But on one condition.”

Hayao’s heart skipped, tension coiling in his gut. “What condition?” he asked, voice low, wary of her sudden intensity.

Yumi’s smile turned wicked, eyes glinting with a secret. She uncrossed her legs, slowly lifting her skirt, revealing racy pink underwear clinging to her hips. With deliberate motion, she hooked a finger under the fabric and pulled it aside, exposing her shaved pussy, glistening with arousal. The sight sent a shock through Hayao, his cock stirring, a primal urge flaring. 

“I know you’re fucking Mom,” she said, voice low and sultry, each word a dagger piercing his secrecy.

Hayao’s breath caught, mind reeling. “What? How—” he stammered, shock and anger surging. Yumi knew? His secret with Mai, their forbidden passion, exposed by his sister?

She cut him off, finger tracing her slit, spreading her wetness. “I’ve heard you two, Hayao. The walls aren’t thick. And I’ve seen how you look at her, all possessive and hungry.” She spread her legs wider, pussy an open invitation, voice dripping with challenge. “If you want the money, you’re gonna fuck me too.”

For a moment, Hayao was frozen, the world tilting. Yumi’s knowledge was a betrayal. And, how dare she spy? How dare she use it? But beneath it, a darker thrill pulsed. Yumi’s brazen offer, her exposed pussy, her crossing the same taboo line, ignited a primal desire. His cock hardened fully, straining against his pants, her arousal overwhelming his guilt. Mai was his, but Yumi’s challenge stirred a need to dominate, to claim her too.

Without a word, he lunged, surprising her with ferocity. Yumi gasped, a mix of shock and delight, as he pushed her back onto the bed, her laughter ringing out. 

“Wow, you’re fucking eager,” she teased, voice breathy, but her words died as Hayao’s hands moved with savage intent.

He yanked down his pants and underwear, cock springing free, thick and throbbing, head slick with precum. Climbing onto the bed, he straddled her chest, knees pinning her shoulders, hands grabbing fistfuls of her long hair. Yumi’s eyes widened, uncertainty flickering, but before she could speak, he shoved his cock into her mouth, thrusting deep with brutal force. The sudden invasion made her gag, throat constricting around his shaft, a choked sound escaping as he fucked her face without mercy.

The feel of her mouth was electric, warm and wet, but it was her throat that drove him wild. Tight and unyielding, it resisted his cock, muscles spasming as he forced deeper, the constriction like a vice gripping him. Each thrust sent a jolt through him, her gags massaging his shaft, the friction intense. 

“Take it,” he growled, voice rough with lust and anger, hips slamming forward, balls slapping her chin. 

Her hands pushed against his thighs, nails digging into his skin, trying to create space, but his grip on her hair was iron, pulling her head to meet each thrust.

Yumi’s throat fought him, convulsing with every plunge, the wet, gurgling sounds of her choking filling the room. Saliva bubbled from her stretched lips, dripping down her chin, pooling on the sheets, a slick mess that coated his cock, making each thrust smoother, deeper. Tears streamed from her eyes, smudging her makeup, her face flushing red as she struggled for air. Her body thrashed, arms flailing, legs kicking against the bed, heels sliding on the sheets, but Hayao’s weight pinned her.

“You wanted this, didn’t you?” he snarled, cock plunging deeper, hitting the back of her throat, making her gag harder. “You’re just like Mom, a fucking whore who loves cock.” 

The words poured out, fueled by rage at her intrusion, arousal at her submission. Her throat’s tightness was exquisite, warm and slick, each spasm sending waves of pleasure through him. He felt every ridge, every contraction, her gags a rhythmic pulse that drove him closer to the edge.

Yumi’s struggles intensified, her gags desperate, hands clawing at his legs, leaving red welts. Her chest heaved, breasts straining against her top, nipples hard beneath the fabric. Her legs thrashed, one foot catching the bedframe, the creak of wood mingling with her choked cries. Hayao’s hands tightened in her hair, scalp burning under his grip, forcing her to take him deeper, his cock lodging in her throat, cutting off her air. The power he wielded, her body yielding to his will, was intoxicating, his balls tightening with impending release.

He pulled back slightly, letting her gasp a ragged breath, saliva dripping from her lips, only to thrust again, deeper, harder. Her throat spasmed, a wet, sucking sound as she tried to swallow around him, the sensation pushing him closer. 

“That’s it. Swallow it, sis,” he commanded, holding his cock deep, feeling her throat work, muscles contracting, milking him. 

Her eyes rolled back, face a mask of pain and submission, tears pooling in her lashes, dripping onto her cheeks. Each thrust was a battle, her throat resisting, then yielding, the warmth enveloping him, the slickness easing his way. 

He varied his pace—slow, deliberate plunges to savor the tightness, then rapid, brutal thrusts that made her choke, her body jerking beneath him. Her hands, once pushing, now gripped his thighs, nails biting, but her strength waned, her resistance fading. Her legs slowed, kicks becoming weak twitches, her body accepting him.

Hayao’s mind was a maelstrom—anger at her knowledge, lust for her submission, a twisted triumph at claiming her. The feel of her throat, so tight it seemed to mold to his cock, was unlike anything with Mai. Oral sex with Mai had undertones of love was tenderness even at its most brutal; Yumi’s was raw, forced, a conquest. Each gag, each tear, fueled his arousal, his cock throbbing with need. He leaned forward, weight pressing her deeper into the mattress, his balls brushing her chin, the scent of her sweat and his precum filling his senses.

Her moans, muffled and pained, vibrated against his shaft, sending shivers through him. He felt her tongue, weak but moving, trying to push against his cock, only adding to the sensation. Her throat’s spasms grew erratic, her body trembling, consciousness slipping. Hayao didn’t stop, driven to punish her audacity, to mark her as his. 

“You’re mine now, Yumi,” he growled, thrusting deeper, the head of his cock lodged in her throat, her gags a desperate plea.

As her resistance crumbled, her body going limp, eyes half-closed, Hayao felt a surge of triumph. His thrusts grew erratic, pleasure building, balls tightening. With a final, savage plunge, he buried his cock, the head pulsing as he came, hot cum shooting directly into her stomach, thick spurts filling her throat. The sensation was overwhelming, her throat convulsing, swallowing reflexively, milking every drop. He held her there, grip tight, until he was spent, her body shuddering, consciousness fading.

Yumi lay sprawled on the bed, her body trembling, gasping for air as she coughed violently, her throat raw from the savage face-fucking Hayao had inflicted. She was half-unconscious, her mind a fog of pain and disorientation, struggling to process the violation of her throat. Her long black hair clung to her flushed cheeks, damp with sweat and tears, her eyes half-closed, fluttering as she fought to stay present. 

Slowly, he pulled out, cock slick with saliva and cum, leaving a trail across her lips. Yumi gasped, coughing violently, chest heaving as she fought for breath, half-unconscious, face a mess of tears, saliva, and running makeup. Hayao watched, a cruel smile spreading, and placed his softening cock on her lips. Weakly, almost instinctively, her tongue flicked out, licking the remnants, tasting the sharp, salty mixture of his release and her own saliva. The act was automatic, her body responding despite her dazed state, her lips quivering as they grazed his skin.

“See, sis?” he said, his voice dripping with venom, a cruel smile twisting his lips. “A natural-born cocksucker, just like Mom.” 

The comparison was a deliberate barb, meant to degrade her, linking her to Mai’s taboo submission. He raised his cock and slapped her face with it, the wet sound sharp and jarring in the quiet room, the impact making her flinch, her cheek stinging from the contact. 

“Wake up, slut,” he growled, his tone laced with contempt. “I’m not fucking done with you yet.”

Her eyes fluttered open, dazed and unfocused, her pupils dilated as she struggled to pull herself from the haze. Hayao slapped her face again with his cock, the head leaving a glistening smear of precum across her cheek, the sensation rousing her further. Her breath hitched, a soft whimper escaping as she tried to focus, her body trembling under the weight of his dominance.

He grabbed her shoulders with rough hands, his fingers digging into her soft flesh, and flipped her onto her stomach with a forceful tug. Yumi’s arms buckled, barely supporting her as he pulled her hips up, positioning her on all fours, her knees sinking into the mattress, her head hanging low, long hair obscuring her face like a dark curtain. Her body swayed, still weak from the earlier assault, her arms trembling as they struggled to hold her weight. Hayao knelt behind her, his hands roaming over her back, feeling the yielding softness of her skin, so different from his mother’s toned, firm body sculpted by gym workouts. Yumi’s flesh gave under his fingers, pliant and warm, her curves inviting in their softness, a stark contrast to Mai.

He slapped her ass, the sound echoing like a gunshot, leaving a red handprint that bloomed across her pale skin. Yumi whimpered, the sting jolting her, her body jerking forward. He slapped her again, harder, watching her ass jiggle with the impact, the sight sending a surge of arousal through him. His hands moved to her breasts, unclipping them from the front and freeing them from her bra. He cupped them from behind, noting their size, nearly matching Mai’s, full and heavy, the weight filling his palms, nipples hard and sensitive under his touch. He pinched them, rolling the stiff peaks between his fingers, drawing a sharp gasp from Yumi, her body arching involuntarily, her breasts swaying with the motion.

“Fuck, Yumi, your tits are almost as big as Mom’s,” he grunted, squeezing them harder, feeling their softness yield, the contrast with Mai’s firm breasts fueling his desire. 

He pinched her nipples again, twisting slightly, eliciting a pained moan, her body trembling under his rough handling. The bed creaked beneath them, the mattress dipping as he positioned himself, his cock, slick from her mouth, brushing against her inner thigh, teasing the edge of her pussy, which glistened with arousal despite her earlier resistance.

With a powerful thrust, he buried himself inside her, her tight, wet heat enveloping his cock, the sensation overwhelming. Yumi cried out, her voice raw, her body jerking forward as his hips slammed against her, the slap of skin against skin echoing in the room. Her pussy was tighter than Mai’s, less experienced, its walls gripping him with a raw intensity that sent shivers through him. He grabbed a fistful of her hair, pulling her head back, forcing her to arch her back, deepening his penetration. Her scalp burned under his grip, her moans a mix of pain and reluctant pleasure, her hands clutching the sheets, knuckles white as she braced herself against his relentless thrusts.

“Fuck, Yumi,” he grunted, his hands roaming her soft curves, fingers digging into her hips, her waist, her ass, contrasting them with Mai’s firm, sculpted form. “You’re so fucking good.” He slapped her ass again, the impact making it ripple, the red handprint darkening, his cock throbbing inside her at the sight. Her pussy clenched around him, wet and hot, each thrust drawing a slick, squelching sound that filled the room, mingling with her gasps and the creak of the bedframe.

He gripped her bunched up skirt as he fucked her, the thought of cumming inside her, a forbidden act with Mai, sent a dark thrill through him. Mai always insisted on him pulling out; her strict rule was a boundary he respected, but Yumi was his to mark, to claim in a way he couldn’t with his mother. The idea of his seed taking root inside her, of Yumi’s belly swelling with his child, her breasts growing even larger, heavy with milk, leaking at his touch—it drove him wild. He imagined her pregnant, her full breasts engorged, milk dripping from her nipples as he sucked them, tasting the sweet, creamy liquid, claiming her body in every possible way. The fantasy consumed him, his thrusts becoming more urgent, his grip on her hips tightening, fingers leaving bruises as his balls slapped against her skin with each powerful stroke.

He leaned forward, his chest pressing against her back, his breath hot against her ear. “I’m gonna fill you up, Yumi,” he growled, his voice thick with lust. “Gonna cum inside you, make you mine.” 

His sister’s pussy tightened at his words, a shudder running through her, her moans growing louder, more desperate. He pulled her hair harder, and her back bent like a bow, her breasts bouncing with each thrust, sending sparks of sensation through her.

With a deep, guttural groan, he came, his hot cum flooding her pussy, thick spurts filling her depths, coating her walls. Yumi gasped, her own orgasm triggered by the sensation, her pussy clenching around him, milking every drop as her body shuddered violently. Her cries filled the room, a mix of pleasure and pain, her hands tearing at the sheets, her body collapsing forward as the intensity overwhelmed her. Hayao held himself inside her, savoring the warmth, the tightness, the way her pussy pulsed around his cock, drawing out his release.

Yumi collapsed onto the bed, her body trembling, tears streaming down her face as she sobbed, her voice raw with fear and betrayal. “How could you, Hayao? Cumming inside your own sister... what if I get pregnant?” Her hands clutched her stomach, her large breasts heaving with each ragged breath, nipples still hard from the intensity of her orgasm. Her pussy, slick with Hayao’s cum, glistened in the dim lamplight, the sheets beneath her stained with their combined fluids. Her long brown hair clung to her flushed cheeks, damp with sweat and tears, her eyes wide with panic as the reality of his act sank in, her body still quivering from the violent climax that had torn through her.

Hayao lay beside her, his chest heaving, his cock softening after the explosive release, slipping out of her with a wet, slick sound, a trail of cum dripping from her pussy onto the mattress. His body was slick with sweat, the musky scent of sex filling the room. Yumi’s sobs echoed, her voice a broken plea, but as she looked at him, a shift flickered in her gaze—a spark of lust, a daring challenge beneath her fear. 

Despite her distress, her body pulsed with lingering arousal, her pussy still throbbing from the orgasm that had consumed her. She reached out, her hand trembling but deliberate, and cupped his balls, feeling their warmth and weight in her palm, the skin soft and slightly wrinkled from his release. Her fingers, slick with their combined fluids, trailed up to his softening shaft, stroking it slowly, her touch both gentle and insistent, coaxing him back to life.

Hayao’s breath hitched at the unexpected sensation, his body stirring despite the post-climax haze. Yumi’s fingers were warm, her grip firm yet teasing, sliding along his shaft with a slow, deliberate rhythm, spreading the slickness of his cum and her juices. Her thumb brushed the sensitive head, circling the tip, drawing a low groan from him as his cock twitched, beginning to harden under her skilled touch. 

She leaned closer, her nipples grazing his thigh, the contact sending a shiver through him, her skin soft and yielding compared to Mai’s toned physique. Yumi’s eyes locked onto his, a smirk playing on her lips, her earlier tears drying as a provocative glint replaced her fear. 

“Does Mom let you cum inside her?” she asked, her voice breathy, laced with curiosity and a taunting edge, her fingers tightening around his balls, rolling them gently, the sensation sending sparks of pleasure through him.

“No,” Hayao replied, his voice low and gravelly, a mix of possessiveness and arousal. “She doesn’t. She’s still young and she doesn’t want me to… You know… get her knocked up.”

Yumi’s smirk widened, her hand continuing to stroke his shaft, feeling it grow firmer, thicker, the veins pulsing under her fingers. 

“Then try and get me pregnant, mother fucker,” she whispered, the term a sharp, taboo-laden jab that sent a jolt of arousal through Hayao. The word “mother fucker” echoed in his mind, a raw reminder of his forbidden bond with Mai, now twisted into this new conquest with Yumi. 

Her challenge, daring him to impregnate her, ignited a primal fire, his cock fully hardening in her grasp, throbbing with renewed need. And, ignited by her words, his mind raced with other fantasies, too. Vivid, depraved images of claiming her in every way possible.

He imagined her on her knees, her large breasts pressed together, his cock sliding between them, the soft, warm flesh enveloping him, her nipples hard as he thrust, her tongue flicking out to lick the tip with each stroke. The vision of her breasts, leaking milk and covered in his cum, sent a shiver through him. He pictured sodomizing her, her tight hole yielding to his cock, her moans a mix of pain and pleasure as he stretched her, comparing that passage with his mother’s. The fantasy deepened—a threesome with Mai and Yumi, mother and daughter entwined, Yumi’s head buried between Mai’s thighs, her tongue delving into Mai’s pussy, lapping at her clit while Hayao watched, stroking himself, before joining in, fucking Yumi from behind as she pleasured their mother. The images flashed through his mind, each more arousing than the last, fueling his desire as he positioned himself between Yumi’s legs, his hard cock pressing against her entrance, still slick with his cum and her arousal.

“You want to fuck my tits, Hayao?” Yumi teased, her voice sultry, her hand guiding his cock to her pussy, rubbing the head against her wet folds. “Or maybe my ass? I’ve never done that, but for you, I might.” Her words were a challenge, a dare that made his cock twitch, her provocative tone stoking the fire within him.

“Fuck, Yumi, you’re gonna do it all,” he growled, his voice thick with lust, his hands gripping her hips as he thrust into her, her tight, wet heat enveloping him. Yumi cried out, her breasts bouncing with the force of his penetration, nipples hard and grazing his chest as he leaned over her. The bed creaked beneath them, the headboard tapping rhythmically against the wall, the sound a primal beat to their passion. Hayao’s hands roamed her body, feeling the yielding softness of her curves.

“God, your body’s so fucking great,” he grunted, his fingers digging into her hips, leaving faint bruises as he thrust deeper, his balls slapping against her skin. 

He cupped her breasts, their weight filling his palms, nearly as large as Mai’s, the softness yielding under his grip. He pinched her nipples, rolling them between his fingers, drawing sharp gasps from her, her body trembling under his rough handling. The contrast between Yumi’s pliant flesh and Mai’s firm but yielding physique fueled his fantasies, his mind racing with images of Yumi’s breasts wrapped around his cock, her tight ass clenching around him, or her tongue buried in Mai’s pussy as he fucked her from behind.

Yumi’s moans grew louder, her hips meeting his thrusts, her earlier resistance melting into a lustful surrender. “Fuck me harder, Hayao,” she gasped, her voice a mix of desperation and desire. “You want to make me your whore, mother fucker?” she taunted, her voice breathy, urging him on. “Then do it—fuck me stupid, cum inside me.”

Hayao’s thrusts intensified, his cock stretching her, the slick, squelching sounds filling the room. He imagined her on her back, Mai beside her, their bodies entwined in a threesome. His hands gripped her hips, fingers digging in, as he pounded into her, the bed shaking, the air thick with the scent of sex.

“Cum inside me, Hayao,” Yumi moaned, her legs wrapping around his waist, pulling him deeper. “Paint my insides, make me yours.” Her words were a provocative plea, her body fully yielding to his dominance. Hayao leaned forward, capturing her lips in a fierce kiss, his tongue invading her mouth, the act raw and possessive. His hands moved to her breasts, squeezing their softness and mauling them, drawing sharp gasps.

“You want it all, don’t you?” he growled, breaking the kiss, his mouth moving to her neck, biting and sucking, leaving marks. “My cock in your tits, your ass, maybe even eating Mom’s pussy while I fuck you.”

Yumi’s breath hitched, her body arching into his touch. “Yes, Hayao, do it all,” she whispered, her voice thick with lust, her hips rocking to meet his thrusts. “Use me however you want.”

His pace turned frantic, the bed creaking, their bodies a blur of passion. The fantasies heightened his pleasure, his balls tightening. With a final, powerful thrust, he came, his cum mixing with the first load, flooding her pussy with thick, hot spurts, the volume overwhelming, spilling out around his shaft. 

Yumi’s orgasm crashed over her, her pussy clenching, milking every drop, her cries echoing as her eyes rolled back, her body shuddering in ecstasy. Her legs tightened around him, holding him deep, her nails raking his back, leaving red trails.

They collapsed together, sweat-slicked and panting, their bodies entwined, the weight of their act sealing a new, dark bond. Hayao’s mind raced with the thrill of crossing this line with Yumi, the taboo of cumming inside her, the fantasies of her body in every possible act fueling his desire. Yumi, trembling, looked up at him with a mix of fear, desire, and reluctant acceptance, her tears drying as she nestled against him, her soft breasts pressed against his chest, her breath warm against his skin. 

The room was silent save for their ragged breaths, the air heavy with the scent of sex, their actions binding them in a forbidden pact.
