The door creaked the smallest fraction under Kushida's weight.
Ren's head turned slightly toward the door.
His eyes locked onto the narrow gap. In the dim spill of lamplight he caught the glint of another pair of eyes of Kushida's.
Her eyes was wide and frozen with shock.
Staring straight past him.
She had not noticed his gaze at all.
Her attention was fixed lower, riveted to the place where their mother's stretched, swollen cunt was being forced open again and again around his thick cock.
Every deep thrust pushed her mother's pink lips wide, the rim of her hole clinging desperately to the veined shaft before it was driven back inside.
Thick cream and clear juice splattered outward with each impact, arcing in wet strings that soaked the already darkened sofa cushions and dripped steadily onto the floor.
The gaping stretch was obscene, glistening, puffy, and greedy, and Kushida could not look away from it.
Ren did not slow down rather he got excited seeing his delicious sister outside of that door.
'It seems I have to put on a show for my beloved sister.'
He kept the same merciless rhythm, hips slamming forward so hard the wet slap of skin on skin cracked through the room.
Slap. Schlick. Slap.
Their mother cried out into the cushions, face twisted in a slutty, broken expression of pure need, hips rolling back to meet every brutal stroke as if her body no longer belonged to her.
"Your father never filled me like this," she sobbed, voice loud and shameless.
"His weak little cock could never stretch me open… never make me this wet… nngh only my son's big dick can ruin his mother's cunt like this."
Kushida's breath hitched. Heat flooded her face and raced straight down between her legs.
The memory of Ren's tongue from that morning flashed through her mind, sharp and unwanted.
She still could not comprehend what she was seeing.
Her twin brother buried to the hilt inside the same body that had carried them both, their mother begging for more while openly degrading the man who was supposed to be her husband.
'This must be a dream,' she thought, pulse thudding in her throat.
'This can't be real.'
Ren's grip on their mother's hips tightened.
He angled his next thrust upward, dragging the fat head of his cock hard against the spot that made her scream.
Juice squirted out around the base of his shaft, splashing across his thighs and adding another dark stain to the bedsheets.
He spoke without looking away from the door gap, voice low and rough, pitched so their mother would hear every word.
"Watch closely," he said, hips never slowing.
"This is how a mother takes her son's cock. Look at the way her hole opens for it. Look how deep she lets it go."
He pulled almost all the way out, the thick shaft glistening, then slammed back in to the hilt.
Schlick.
Their mother's pink lips stretched wide around the base, the rim clinging and fluttering as cream foamed out with every thrust.
Juice splattered across the room in wet arcs.
"You feel that, Mom?" Ren growled against her ear.
"Your cunt was made to swallow this. The same hole that pushed me out is taking every inch like it belongs to me.
A good mother learns to open up for her son. She learns to beg for it. She learns to take it until she's dripping and ruined."
Their mother sobbed into the cushions, hips pushing back hard to meet him.
"Yes… ah… fill me… stretch your mother's pussy… your father never could… only you…"
Behind the door, Kushida's breath came shallow and fast.
Heat throbbed between her legs like a stove left burning.
All morning Ren had teased her without mercy, fingers and tongue blackmailing her, keeping her right on the edge and never letting her fall over. Her clit still ached from it.
The memory alone made fresh wetness slick her folds.
'I can't stop looking,' she thought, eyes locked on the place where their mother's stretched pink hole kept swallowing the thick length of her twin brother's cock.
Schlick-schlick-schlick.
Every thrust forced it open wider. Every withdrawal left it gaping for a second before it was filled again. The wet sound and the broken moans filled her ears.
Kushida's hand slipped under the waistband of her sleep pants.
Fingers slid down over her soaked panties, then under the fabric.
She found her swollen clit and rubbed in tight, desperate circles, staring at the filthy rhythm of their mother's cunt taking cock.
Her hips twitched forward against her own hand.
Excitement pulsed through her in sharp waves. She bit her lip hard to stay quiet, but a tiny sound still escaped.
Ren's gaze stayed fixed on the door gap.
He saw the slight movement of her arm, the way her shoulders tensed.
A dark, satisfied smile tugged at the corner of his mouth even as he kept pounding into their mother.
"That's it," he said, voice still aimed at the woman beneath him, yet every word carried.
"A mother opens her legs for her son. She takes him deep. She gets her hole used until it remembers the shape of his cock. Mom, you should teach your used pussy how to massage my dick once it gets inside you, right?"
"Ahh..., I..will..teaccch mmmy puus..sy."
He angled his next thrust upward and ground hard against the spot that made their mother scream.
Fresh juice squirted out around his shaft soaking the cushions.
Her walls clamped down in another climax, milking him in tight pulses while she cried out filthy praise for how much better her son filled her than her husband ever had.
Kushida rubbed faster, fingers slick, pussy twitching with every wet sound from the room.
The burn between her legs only grew hotter.
She stared at the stretched pink rim clinging to Ren's cock, at the cream dripping down, at the way their mother's body moved like it had already accepted its new purpose.
'It looks so wet… so open…' she thought, hips jerking against her hand.
The teasing from the morning left her so sensitive that every circle of her fingers threatened to tip her over, yet she kept going, unable to stop watching.
Her fingers slipped lower. She pushed one inside herself, then a second, thrusting them in and out in time with the wet slap of Ren's hips.
Schlick. Schlick.
A soft, shaky moan slipped past her lips, but it was completely drowned out by their mother's loud, whoreish cries.
'Brother should be tormenting me like always,' Kushida thought, jealousy twisting darker in her chest as her fingers kept pumping.
'But he never did this with me. Does he love her body more than mine? Will he stop blackmailing me and stop touching me?'
The thought only made her push deeper, watching the way their mother's pink hole stretched and swallowed every thick inch, cream foaming around the base of Ren's cock while the older woman sobbed and begged for more.
'He's never carried me like that. Never held me open and fucked me where I could see everything. He always stops before I finish. Why does she get the full thing? Why does her pussy get to take him like that while I'm left aching? I'm more young and fresh. I'm also still virgin.'
Without warning Ren wrapped his arms under their mother's thighs and lifted her clean off the bed.
His cock stayed buried deep inside her as he stood and carried her the short distance to the doorway.
He stopped right in front of the gap, holding their mother with her back against his chest, legs spread wide, her stretched pink hole fully on display only some inches from Kushida's face.
Then he started thrusting again.
The new angle made every stroke clear and brutal.
Kushida could see the exact way their mother's cunt lips clung to the thick shaft, the wet cream that squeezed out with every push, the way her entrance stretched obscenely around the base before being forced open again.
Juice dripped straight down onto the floor between them.
Drip. Drip.
Their mother moaned louder than before, head falling back against Ren's shoulder, breasts bouncing with each upward thrust.
"Yes… deeper… use your mother's hole… fill me…"
Kushida's fingers thrust harder inside herself. Excitement and jealousy crashed together so hard her thighs trembled.
'He's showing me on purpose,' she thought, eyes wide, unable to blink.
'He knows I'm here. He's making me watch how her pussy takes every inch while mine is empty. Does he want her more? Is her body better than mine? Why does she get to be full while I'm left rubbing myself in the dark like this?'
Ren's eyes met hers through the gap for a single second.
He never slowed the deep, wet thrusts that kept their mother's ruined hole stretched wide open right in front of his twin sister.
The thrusting grew more intense.
The wet slap of skin turned into sharp, relentless clapping that filled the living room and echoed out into the hallway.
Slap. Schlick. Slap. Schlick.
Every upward drive forced another gush of cream out around his cock.
Their mother's ahegao deepened, tongue out, eyes rolled back, broken moans spilling freely.
"Take it all, Mom," Ren growled against her ear.
He buried himself to the hilt and came hard.
Thick ropes of cum pumped deep into her, pulse after pulse flooding her womb until it had nowhere else to go.
The excess pushed out around the base of his cock in creamy white rivulets that dripped down his balls and onto the floor.
Squelch.
He kept grinding upward through the climax, forcing every drop as deep as it would go.
Their mother's walls clenched and fluttered wildly around him. Her ahegao deepened further as the hot flood filled her.
'I'll be pregnant with all of this cum in my womb,' she thought, the words filthy and clear even as her body shook.
'My son is going to give me another baby. He's breeding me. He's pumping me full until it takes. I want it. I want his baby inside me.'
At the exact same moment Kushida's own orgasm ripped through her.
Her fingers curled deep inside as her pussy clenched hard and she squirted, a sudden clear rush soaking through her sleep pants and drenching the floorboards beneath her feet.
Splat.
A choked, shaky moan escaped her, completely lost under their mother's loud, satisfied cries.
Ren did not stop.
He carried their mother back into the room, still buried inside her, and dropped onto the bed with her straddling him in reverse.
He gripped her hips and bounced her hard on his cock, the wet sound of her cum-filled hole sliding up and down the thick shaft filling the air again.
Later he bent her over the arm of the sofa, one hand fisting her hair while he drove into her from behind, the sharp sound of his hips against her ass echoing through the house.
At one point he had her on her back on the floor, legs folded open, pounding down into her with long deep strokes that forced more white cream out around his cock with every thrust.
Schlick. Squelch. Schlick.
The night stretched on with the continuous wet sounds of mother and son, the filthy moans, the wet slap of skin, the soft filthy words Ren kept feeding her while he used her pussy hole as he wanted.
Outside the door Kushida remained on her knees, sleep pants soaked, fingers still weakly rubbing her throbbing, oversensitive pussy.
She could not leave. She could not look away.
She should've been relieved by the fact that he lost interest in her body that he will probably won't blackmail her anymore.
But jealousy and helpless heat twisted together in her chest as the debauchery continued without her.
Ren's gaze drifted once more toward the gap in the door.
A thin trail of clear pussy juice was slowly seeping across the floorboards from the hallway into the room.
'Mom is mine now,' he thought, a dark satisfaction settling in his chest as he kept moving inside her.
'Only Kushida remains. But it seems like she'll be an easy meat as she will be asking for my validation through my dick.'
