Ren stepped deeper into the room. His eyes moved from Kikyo's open legs to Ayako's bound, trembling form.
He walked forward until he stood right beside the bed and stopped in front of his mother's face.
The thick bulge in his pants hovered only inches from her lips.
The hard outline pressed clearly against the fabric, heavy and already fully erect from the sight of both of them.
Ayako stared up at it, eyes wide with panic and the same unwanted heat that had betrayed her earlier.
Her breath came quick and shallow against the ropes that held her.
Ren turned his head slightly toward his sister without looking away from their mother.
"Kushida. Come here and take my clothes off."
His voice was calm, low, and absolute.
Kikyo climbed off the bed and moved to her mother's side, still completely naked.
She stood close enough that her bare thigh brushed Ayako's bound arm.
Ayako's voice cracked with desperation.
"Son… not in front of her. Please."
Ren looked down at her with calm certainty.
"Mom, she has already seen us fucking in the kitchen and in your bedroom. If we don't agree to her command, Kushida will tell Dad about our deep-buried adventures."
He leaned down and captured his mother's soft pink lips in a slow, obsessive kiss.
His mouth moved against hers with deliberate hunger, tongue sliding past her teeth as he claimed her right in front of her daughter.
Ayako's eyes fluttered.
A muffled sound escaped into his mouth even as her mind raced in panic.
'She has seen us… my degrading state… she will tell that bastard… what should I do?'
Ren deepened the kiss without warning.
His tongue pushed past her lips and swirled roughly around hers, claiming every soft corner of her mouth with hungry insistence.
The gentle pressure from before vanished.
This was pure ownership.
Ayako's panicked thoughts shattered under the sudden intensity.
"Mmph… nnh…"
A helpless whimper vibrated against his tongue as her body betrayed her again.
Her heavy breasts rose and fell faster against the ropes.
The unwanted wetness between her bound thighs grew thicker while her son kissed her with the same rough, obsessive hunger he had used when he filled her before.
While Ren kept his mother's mouth occupied with the rough, swirling kiss, Kikyo sank to her knees beside the bed.
Her hands reached for the waistband of his pants. She unbuttoned them slowly, then dragged the zipper down with deliberate care.
The fabric loosened.
She hooked her fingers into the waistband and pulled both pants and underwear down in one smooth motion.
Ren's fully erect cock sprang free at once, thick and heavy, the broad head already glistening with a clear bead of precum.
It slapped upward against his lower stomach with the sudden release, standing rigid and veined only inches from Ayako's face like a criminal finally set free from a long confinement.
Ayako's eyes locked onto it even as her son's tongue continued to claim her mouth.
A fresh whimper slipped past their joined lips.
Kikyo's eyes narrowed as she watched her brother devour their mother's mouth.
Jealousy burned hot and sharp in her chest.
She refused to be ignored.
She leaned forward and slowly dragged her tongue across the glistening tip of Ren's cock, licking away the thick bead of precum that had gathered there.
Ren shivered at the wet contact.
The sudden pleasure made his kiss turn even rougher.
He crushed his mouth harder against Ayako's, tongue thrusting deeper, claiming her with hungry insistence.
Ayako's resistance finally cracked.
A soft, broken sound escaped her throat as her own tongue began to move against his, responding in slow, reluctant swirls.
Her heavy breasts rose and fell faster against the ropes while her daughter's tongue continued to tease the sensitive head of her son's cock only inches from her face.
Kikyo tried to copy what she had seen in porn.
Her tongue moved clumsily along the thick shaft while one hand reached up to cup and gently massage Ren's heavy balls.
The movements were awkward and inexperienced, but the wet heat of her mouth still sent fresh pulses of pleasure through him.
Schlick… schlick…
Ren's thoughts stayed calm even as his body reacted.
'It seems my sister's main objective from the start was making me blackmail her into becoming mine. She needed me to love her real character not the fake angel persona she usually showed and was got caught in her school. But the system showed resistance that means she doesn't even aware of it herself.'
He never broke the deep kiss with their mother.
One of his hands slid down and closed over Ayako's heavy breast, kneading the soft, full weight of it with slow, possessive pressure.
His fingers sank into the warm flesh, thumb brushing across the tight nipple while his tongue continued to claim her mouth.
Ayako whimpered into the kiss, her bound body trembling as her son groped her and her daughter licked and massaged him right beside her face.
Kikyo's jealousy finally boiled over.
Seeing that her brother still refused to break away from their mother's mouth, she made a sudden decision.
In one sharp movement she opened wide and forced the thick head of his cock past her lips, swallowing nearly half the length in a single desperate push.
Her jaw stretched painfully around the massive girth.
A wet gagging sound tore from her throat, but she did not pull back.
Tears pricked at the corners of her eyes as she held him deep, her tongue pressed flat against the underside while saliva began to spill from the corners of her stretched lips.
Schlick… glrk…
The sudden tight, wet heat finally pulled Ren's attention. He broke the kiss with Ayako and looked down.
Ayako's eyes followed his gaze.
She stared at her daughter's face stuffed full of her son's cock, the thick shaft disappearing between Kikyo's stretched lips.
A fresh wave of unwanted wetness flooded between her own bound thighs at the filthy sight.
Ren's voice was calm and cutting.
"Mom, your daughter is more obedient than you. Should I leave you here alone with Dad and go with Kushida to Advanced Nurturing High School?"
Ayako's face crumpled with real fear at the thought of being left alone with her husband.
Tears welled in her eyes and spilled over.
"Please don't leave me, son. I will do anything. Please don't leave me with that fat pig. I will be all alone if you both leave me in this house."
Ren looked down at her, a little stunned.
He had only been half-joking, yet the genuine panic in her voice caught him off guard. He reached up and gently wiped the tear from her cheek with his thumb.
Then he leaned down and kissed her again, this time soft and reassuring.
"Don't worry, Mom. I won't ever leave you alone with that whore-loving bastard. I'll do something so that you can get a job inside the ANHS."
Below them Kikyo kept working.
Hearing the soft words he spoke to their mother only made her more determined.
She remembered the clumsy morning blowjob and tried to improve.
Her tongue moved more carefully along the thick shaft, circling the head and pressing against the sensitive underside while she took him as deep as her stretched jaw would allow. Soft wet sounds filled the quiet room as she focused entirely on pleasing him.
Schlick… schlick…
Ren's hand settled on the back of her head.
"Stop moving."
She froze instantly. He slowly pulled his cock free of her mouth.
A wet pop sounded as the thick head slipped past her lips, leaving a glistening string of saliva connecting them for a moment before it broke.
Ren looked at his sister.
"Help me move Mom. I want her bent over on the bed with her legs spread. Adjust the ropes so she stays like that."
Kikyo rose without hesitation.
Together they lifted and turned Ayako's bound body.
Ren guided her onto her knees, then pushed her upper body down until her heavy breasts pressed into the mattress.
Kikyo worked quickly, loosening and retying the ropes around her mother's ankles and thighs until Ayako's legs were forced wide apart, her glistening pussy and tight pink asshole fully exposed and presented.
Ayako whimpered into the sheets, her face turned sideways, unable to close her legs or move her arms.
From this new position every part of her was laid bare.
Her full thighs, soft and pale, trembled against the ropes that kept them spread.
The thick, smooth flesh of her inner thighs quivered with each shallow breath, the skin gleaming faintly with the same nervous sweat that coated the rest of her body.
Her hips, rounded and womanly, shifted helplessly against the mattress.
Her heavy breasts, crushed beneath her, still managed to spill outward with every movement.
Each time she tried to rock or flinch they swayed and bounced against the sheets in a lewd, taboo rhythm, the soft flesh rising and falling as if already being used.
Her back arched slightly under the strain of the ropes, the curve of her waist leading down to the full, rounded cheeks of her ass.
Between those cheeks her small, pink asshole was clearly visible, tight, puckered, and completely exposed.
Just below it, her pussy sat open and wet. The soft outer lips were flushed a deeper pink, the inner folds glistening.
Her pink slit twitched visibly, the little hole clenching and relaxing as if already searching for something to fill it.
She had shaved everything away. Not a single strand of hair remained.
The entire area was smooth and bare, as clean and open as a freshly emptied room, leaving nothing to hide the way her body was reacting.
Ren stepped in behind her. His thick cock, still wet from Kikyo's mouth, hovered just in front of that twitching slit.
He glanced at his sister.
"Kushida. Take my cock in your hand and push it into mom."
Kikyo's eyes widened.
For a second the usual sharp edge in her expression softened into something almost childish.
She pouted, lower lip pushing out in a cute, jealous way that did not match her usual personality at all.
"No, Brother… why does she get to receive it first? I wanna taste your dick first."
Ren's expression eased seeing her expression.
He reached out and patted her head gently, the corner of his mouth lifting in a small smile as he looked at how openly jealous and adorable she had become.
"I'm saving you for later. You're my favourite girl after all."
The words hit her harder than any command.
A bright, almost embarrassed happiness flickered across her face even as she tried to keep the pout.
She looked down, cheeks faintly pink, then gave a small, obedient nod that contradicted everything she had just said.
"…Okay. Let Mom feel it first."
She wrapped her fingers around the thick shaft of her brother's cock.
The heat of it made her breath catch.
Slowly she guided the broad, glistening head forward until it pressed against the soft, wet folds of their mother's pussy.
Instead of pushing in right away she began to rub it up and down the slit, dragging the fat tip through the slickness, teasing the twitching entrance and smearing precum and her mother's own juices along the bare, smooth skin.
Ayako's hips jerked against the ropes. A needy, broken sound spilled from her lips.
"Ah… nnh…"
Kikyo leaned closer, still rubbing the thick head slowly through the wet folds, and spoke in a low, smirking voice.
"Mom. You have to beg for it, or I won't put it in your loose pussy. Beg like a whore in the porn videos or I won't let you enter it in your pussy. Rather I will take it in my folds as my young pussy is fresh, more tight and a perfect fit for my brother. "
'Did my cute sister started watching corrupted porn or anything, where did she learn to talk like this?'
Ayako's face burned with shame against the sheets hearing her daughter's raw words.
But he ache between her legs had grown unbearable as she didn't care about the relationship between them anymore.
Her pink slit kept twitching around nothing, her empty walls clenching in desperate little spasms.
She could feel every slow drag of that heavy cockhead teasing her entrance, and the shame of her daughter holding it only made the heat worse.
Her voice came out cracked and broken.
"Kikyo… please… put your brother's dick in my pussy. I'm a whore who deserves to have a dick in my loose pussy all the time…"
A satisfied smirk curved Kikyo's lips.
Without another word she lined the thick head up properly, then shoved forward in one firm push at the same moment Ren rolled his hips.
The huge cock forced its way into the tight, wet canal of their mother's pussy.
Schlick…
"Nnhh… aaahhh…"
Ayako's entire body seized. Her walls stretched wide around the sudden intrusion, the thick shaft sliding deeper.
Schlick… schlick…
Her heavy breasts, still pressed to the mattress, bounced hard with the force of the thrust.
Her thighs trembled violently against the ropes. Her pink asshole clenched tight in reflex.
Then the pressure inside her snapped.
A sharp, helpless cry tore from her throat as her pussy convulsed hard around her son's cock.
Clear fluid squirted out around the thick shaft in messy pulses, splattering against Ren's hips and Kikyo's hand as the orgasm ripped through her.
"Ahhh… nnngh… Ren… I'm… c-cumming…"
Her bound body shook, thighs quivering, breasts still bouncing with every aftershock while the thick cock remained buried deep inside her twitching, squirting cunt.
