He stayed buried to the hilt, letting her body adjust to the sudden invasion.
Her walls fluttered and clenched in tight rhythmic waves, trying to push him out and pull him deeper at the same time.
Every tiny movement made her gasp.
The stretch was relentless. His girth forced her open wider than anything she had ever felt, the head pressing against places that had never been touched.
Ren looked down at the place where their bodies joined.
Her pink lips were stretched thin around the thick base of his cock, the skin shiny with her juices.
He pulled back slowly, watching inch after glistening inch emerge, coated in her cream, then pushed forward again in one long smooth stroke.
Schlick.
She cried out, legs shaking. Her hands flew to his arms, fingers digging into the hard muscle as if she needed something solid to hold onto.
He did it again, slower this time, dragging the ridge of his head along her inner walls until she was whimpering.
"Look at this greedy cunt," he muttered, voice low and filthy.
"My own mother's pussy swallowing her son's cock like a cheap whore. You were made for this, weren't you?"
She turned her face away, shame burning across her cheeks, but her hips lifted to meet the next thrust.
Ren gripped her thighs and spread them wider, opening her completely.
He set a steady rhythm, long deep strokes that filled her completely on every push and left her empty and aching on every withdrawal.
The wet sounds of their joining filled the room.
Schlick...Schlick...Schlick.
Each thrust forced a soft broken sound from her throat.
Her breasts bounced with the motion.
Ren leaned down and latched onto one swollen nipple, sucking hard, tongue swirling around the peak while his hips kept driving forward.
He pulled and sucked with the same hungry force he had used earlier, treating her breast like it still belonged to him in every way.
"Nnnngh… Ren…" she moaned, the sound cracking.
He released the nipple with a wet pop and moved to the other one, biting down gently before sucking again.
"You're dripping all over your son's cock, Mom. This tight little hole is soaking me. Admit it. You love being stretched open by the same dick that just flooded your throat."
Her voice came out broken.
"I… I shouldn't… but it feels so good… so deep…"
"That's right. Say it properly." He slammed forward harder, the impact forcing a sharp cry from her.
"Tell me whose pussy this is."
"Yours… it's yours, Ren. My son's pussy…"
The words made his cock throb inside her. He rewarded her by angling his hips so the head dragged over the sensitive spot on every stroke.
Her reaction was immediate.
Her back arched again, a fresh wave of cream flooding around his cock, making the next thrust even wetter and louder.
"Louder. I want to hear my mother admit she's nothing but a cumdump for her own son."
She sobbed the words between thrusts.
"I'm your cumdump… your whore… just use me… fill me up…"
He fucked her deeper, the wet slap of skin on skin joining the filthy sound of his cock moving through her soaked cunt.
Schlick. Slap. Schlick. Slap.
Her third orgasm of the night crashed over her without warning. Her walls clamped down hard, milking him in tight rhythmic pulses.
She screamed, body locking up, more juice squirting out around his thrusting cock and soaking the sheets beneath them.
Ren kept moving through it, fucking her through the climax until she was sobbing with overstimulation, his mouth still working greedily at her nipple.
Even then he did not stop.
He slowed only enough to let her catch her breath, then resumed the deep steady strokes that kept her right on the edge.
Her legs wrapped around his waist on pure instinct, heels digging into his lower back as if she was afraid he might pull away.
He had no intention of pulling away.
He lifted one of her legs higher, changing the angle so he could drive even deeper.
The new position made her eyes roll back.
Every thrust punched a soft broken sound from her throat.
Her free hand reached down between them, fingers finding her own clit and rubbing in frantic circles while he fucked her.
"That's it, you filthy slut," Ren growled against her breast.
"Play with your clit while your son ruins this tight cunt. Beg me to breed you."
The dual stimulation pushed her higher again.
Her walls fluttered and squeezed around him without rest.
The room was filled with the continuous wet noise of their bodies, the smell of sex thick and heavy in the air.
"Please… breed me… fill your mom's womb… I need it…" she gasped, the words spilling out in a desperate rush.
He leaned down harder on her nipple, sucking and biting while his hips pounded into her.
The combination sent her spiraling into another climax almost immediately.
She came hard, body shaking, pussy clamping down so tightly he had to fight to keep moving through the intense pressure.
Ren groaned against her breast, the vibration traveling through her.
He was fully hard again now, the residual sensitivity from his earlier orgasm fading under the tight wet heat of her cunt.
He pulled out completely for a moment, looking down at the gaping, dripping hole he had just stretched open.
Her entrance fluttered, trying to close, a thick string of cream connecting the tip of his cock to her folds.
He rubbed the head up and down her slit again, collecting more of her juices, then pushed back inside with one smooth thrust.
She took him easier this time, her body already adapting to his size even as it still struggled to accommodate the girth.
"Still so fucking tight for a mother who's taking her son's cock," he muttered. He set a harder pace, the wet slap of his hips against hers growing louder.
Slap. Schlick. Slap.
She met every thrust now, hips lifting to take him deeper.
The shame had not disappeared, but it had been drowned under the relentless pleasure and the degrading words he kept feeding her.
Every time he pulled back she felt empty and needy. Every time he pushed forward she felt claimed in a way that terrified her and made her drip harder.
"Tell me how it feels having your only son's cock balls-deep in the same hole that pushed him out," he ordered, voice rough with lust.
Her voice came out broken and breathless.
"It feels huge… too big… stretching me open… filling me so deep I can barely think. I love it. I hate that I love it. Please don't stop… use your mom's cunt like the whore it is…"
The admission made his cock throb harder inside her.
He rewarded her honesty with harder thrusts, driving into her with enough force to make the bed creak.
Her moans turned into continuous broken cries. Another orgasm built fast, her walls starting to flutter and tighten in warning.
This time he did not let her finish alone.
He reached between them, pushing her fingers aside, and rubbed her clit himself in tight rapid circles while his cock pounded into her.
The dual assault shattered her.
She came with a loud cry, body convulsing, pussy clamping down so hard he had to slow for a moment just to keep moving through the intense pressure.
He kept rubbing her clit through it, drawing the climax out until she was shaking and gasping for air.
Only then did he ease the pressure, returning both hands to her thighs so he could hold her open and fuck her with long deep strokes once more.
"You're going to take every drop I give you next," he said, leaning down to suck hard on her other nipple.
"I'm going to pump this used-up mother pussy full until it's leaking down your thighs. And you're going to thank me for it."
She nodded frantically, tears of overstimulation at the corners of her eyes.
"Yes… thank you… thank you for fucking your mom… for stretching me… for making me your personal hole…"
The wet sounds of his cock moving through her never stopped.
Schlick...Schlick...Schlick...
He flipped her onto her hands and knees without warning, pulling out only long enough to reposition her.
The moment she was on all fours he slammed back inside, the new angle letting him drive even deeper.
She cried out, face pressed into the mattress, hands fisting the sheets.
Ren gripped her hips hard and set a punishing pace, the wet slap of his body against her ass filling the room.
From this position he could see everything.
The way her stretched hole swallowed his cock on every thrust.
The cream that coated him and dripped down onto the sheets. The way her back arched and her ass pushed back to meet him.
He reached around and found her clit again, rubbing it while he fucked her.
She came almost immediately, the orgasm forcing a fresh squirt of juice out around his thrusting cock.
He kept going, chasing his own second release now, the tight wet heat of her cunt making it harder to hold back with every stroke.
"Look at you," he growled, slamming in hard.
"My mother on her knees like a bitch in heat, taking her son's cock to the hilt. You're nothing but a breeding hole for me now. Say it."
"I'm nothing but a breeding hole for my son," she sobbed into the sheets, pushing back to meet every brutal thrust.
"Use me… fill me with your precious cum…"
He leaned over her back, one hand still working her clit, the other reaching under to squeeze and pinch her hanging breasts, rolling the nipples between his fingers.
The dual assault of deep pounding and constant stimulation kept her locked in a cycle of rising and crashing orgasms, each one leaving her more sensitive and more broken.
Sweat slicked both their bodies.
The sheets beneath them were soaked. The air in the room was thick and heavy with the scent of pure sex. And still he fucked her, relentless, degrading, claiming every inch of the body that had once carried him as his own personal toy.
The wet slap of skin and the broken, high-pitched moans carried faintly up the stairs, thin enough that they almost blended with the night air.
Kushida stirred in her bed, brow furrowing.
She had been half-asleep, one arm flung over her eyes, when the sound filtered through the wall.
"Ahhh...ah.."
She sat up slowly, listening. Another moan followed, low and strained, unmistakably her mother's voice.
Kushida's pulse quickened.
'Dad was supposed to be away on his work like usual. Or had he come home early?'
She swung her legs out of bed, bare feet silent on the floorboards, and eased her door open.
The hallway was dark.
The sounds grew clearer as she moved toward the stairs. Soft cries. The creak of a mattress.
A deeper voice murmuring something filthy she couldn't quite catch.
She descended carefully, heart thudding.
At the bottom she paused outside the living-room doorway, the door left slightly ajar.
Light from a single lamp spilled through the gap. Another wet sound, louder now. Another moan that cracked into a sob of pure need.
'Is Dad home?' she thought, fingers resting lightly on the frame. 'Or is it someone else?'
She pushed the door open another inch.
The scene hit her like a physical blow.
Her mother was on her hands and knees on the sofa, face pressed into the cushions, back arched hard.
Ren, her twin brother, was behind her mom, gripping her hips with both hands, driving his thick cock into her with deep, relentless strokes.
Every thrust forced a wet sound from her stretched pussy and a broken cry from her throat.
Her breasts swayed heavily beneath her. Sweat shone on both their bodies.
The sheets beneath them was already dark with her juices.
Kushida froze, breath locked in her chest.
Ren's voice was low, rough, almost casual in its filth.
"That's it. Take it. My mother's cunt was made for this. Nothing but a breeding hole for her own son. Say it again."
Their mother sobbed into the cushion, hips pushing back to meet every brutal stroke.
"I'm nothing but a breeding hole for my son… nngh…"
Ren's hand slid under her, fingers finding her clit, rubbing in tight circles while he kept pounding.
She came again almost instantly, body locking up, a fresh gush of cream spilling around his cock and dripping onto the fabric.
He never slowed. He only growled approval and fucked her through it.
Kushida's hand flew to her mouth.
The door frame bit into her shoulder as she leaned harder against it, eyes wide, unable to look away.
Her twin brother's cock, thick and glistening, the same one she had seen couple of times as he blackmailed her to give him handjob, was buried to the hilt inside their mother.
And their mother was moaning like a whore, begging for more, calling herself his cumdump while he degraded her with every word.
Ren pulled almost all the way out, showing the way her swollen pink lips clung to him, then slammed back in to the root.
The wet slap of his hips against her ass filled the room.
"Look at this greedy pussy hole," he muttered.
"Still so tight after pushing me out. You're going to take every drop, Mom. You're going to thank me when I pump your womb full. Your husband never stretched you like this, did he? That weak cock of his could never fill you the way your own son does."
"Yes… ah… thank you… thank you for fucking your mom… for stretching me… your dad doesn't know how to… nngh… he never made me feel this full… this used…"
Kushida's knees felt weak. Heat flooded her face, her chest, lower to her pussy as remembering the tongue of Ren from the morning.
She should have stepped back. She should have closed the door and gone upstairs and pretended she had never heard a thing.
Instead she stayed rooted, watching her twin brother claim their mother with long, deep, merciless strokes while the older woman sobbed with overstimulated pleasure and pushed back for more.
The door creaked the smallest fraction under Kushida's weight.
Ren's head turned slightly toward the door.
