Soobin wakes up in the middle of the night, his breath coming in short, ragged gasps as the remnants of the nightmare cling to his mind like a cold sweat. His heart pounds against his ribs, and the darkness of his own room feels suffocating. He always has trouble sleeping, he's always lost in insomnia.
Soobin has been anxious for a long time, afraid that his mother will get married and find a new man. A new man who isn't him. He definitely needs to change that.
Without thinking, driven by a primal need for comfort, he slips out of bed and pads silently down the hallway toward Beomgyu's room.
He pushes the door open with minimal noise, the faint glow from the hallway casting a sliver of light across the bed where Beomgyu sleeps peacefully. The sight of his mother immediately eases some of the tension in Soobin's chest. He crawls onto the bed, moving carefully so as not to startle her, and settles himself close to her warm body.
Beomgyu stirs slightly at the movement, letting out a soft, sleepy hum. "Soobin ah...? What's wrong, baby?" she mumbles, her voice thick with sleep as she instinctively shifts to make room for him. Even in her half conscious state, her first instinct is to soothe her son. She turns onto her side, facing him.
Soobin doesn't answer with words. Instead, he approaches the bed, throwing himself on top of his mother's body. Her scent was magnificent. His hands wander upward, seeking the familiar softness of her breasts beneath her thin nightshirt. His need isn't just for comfort; it's a deep, aching hunger that only she can satisfy.
Soobin's fingers find their way under the hem of Beomgyu's thin nightshirt, his palm brushing against the warm, soft skin of his mother's stomach before moving higher. As his hand approaches the swell of her breast, Beomgyu's eyes flutter open halfway. A drowsy haze still clouds her mind, but she instinctively presses her arm against her chest, gently blocking his wandering hand.
"No, Soobin ah... not now," Beomgyu murmurs sleepily, her voice soft and strained with exhaustion. "You're too big now, baby. It's late, let's just sleep." She tries to pull away slightly, her body seeking the comfort of rest rather than attention, still treating him like the little boy who needs naps rather than the young man seeking stimulation.
Soobin never really lost the habit of sucking on her breasts. Of course, it was a practice he should have stopped a long time ago. However, he was really a very spoiled boy.
Soobin doesn't retreat. Instead, he shifts closer, pressing his large frame against her delicate body until she can feel his heat. He nuzzles his face into the crook of her neck, his lips brushing against her sensitive skin as he speaks in a voice that is impossibly sweet, almost whiny, like a spoiled child begging for a treat.
"Mommy... please?" Soobin whispers, his breath hot against her ear. "I had a bad dream. I can't sleep without feeling you. Just for a little bit? Please, Mommy... I need it." He presses his cheek against her shoulder, looking up at her with big, pleading eyes that he knows she can never resist. "Pretty Mommy. Just to help me sleep."
Beomgyu stares at Soobin for a few moments, her heart melting at the pathetic, pleading expression on his face. She looks at his large frame pressed against her small one, seeing how vulnerable he seems despite his size. Her maternal instincts override her exhaustion; she has always been unable to say no to him when he uses that sweet, helpless tone.
"My poor baby..." Beomgyu sighs softly, her resistance crumbling completely. "You really can't sleep without it, can you?" She reaches out with a tender hand, stroking Soobin's hair away from his forehead. "Fine, fine. Just for a little while, okay? So you can calm down and go back to sleep."
She reluctantly moves her arm away from her chest, pulling the fabric of her nightshirt upward to expose her soft, breasts to the cool air. Her nipples are already peaked from the slight chill, pink and sensitive. Beomgyu settles back against the pillow, opening her legs slightly to make more space for him to nestle between them.
Soobin doesn't waste a single second. A small, satisfied sound escapes his throat as he immediately dives forward. He captures one of her pink nipples between his lips, swirling his tongue around the sensitive bud before taking the entire tip into his mouth. He begins to suckle hungrily, his tongue working against the soft flesh. The familiar taste and texture immediately send a wave of relief through him, his body relaxing as he focuses entirely on the pleasure of tasting his mother. Beomgyu lets out a soft, involuntary whimper, her back arching slightly as she feels the warm pressure of his mouth on her sensitive nipple.
Beomgyu's breathing quickens. She feels a strange, unfamiliar heat spreading through her lower belly. "Soobin ah..." she gasps softly, her fingers tangling in his hair. "You're being... you're sucking so hard today." She notices how his teeth occasionally graze her sensitive nipple, sending jolts of pleasure pain through her body. The way he nuzzles into the soft cleavage of her breasts feels different.
It was difficult for Beomgyu to lie that needles weren't pleasurable.
His grip on her body tightens, pulling her small frame flush against his hard chest. "You're acting like a hungry little monster," she murmurs, though there is no real reproach in her voice, only a dazed confusion at the sudden intensity of his actions.
Beomgyu's body betrays her. The way his mouth wraps around her nipple, the warm suction pulling at her sensitive flesh, and the way his large hands roam across her body makes her breath catch in her throat. A strange, tingling sensation spreads between her thighs, a heat she hasn't felt in years or perhaps ever.
She freezes for a split second, her eyes widening as she stares at the ceiling. "This feels... different", she thinks, her heart beginning to race for an entirely different reason. "He's my son. He's grown so big, but he's still my baby boy."
She knows she should probably push him away, tell him to stop, and insist he sleep in his own bed. It feels wrong morally wrong to feel this pleasant reaction to his touch. She feels like she is failing as a mother by not setting a boundary, by letting him indulge in this intimate habit that seems to be crossing an invisible line.
"Soobin ah..." she whispers, her voice trembling slightly. "Maybe... maybe we should stop for tonight. You're getting too rough." She tries to gently push at his shoulders, her small hands unsteady. But even as she speaks the words of reprimand, her body betrays her again; the soft moan that escapes her lips sounds more like encouragement than rejection, betraying how sensitive she has become to his mouth.
Soobin doesn't even flinch at her words. The gentle reprimand from Beomgyu falls on deaf ears, drowned out by the blood rushing in his ears and the overwhelming need to be closer to her. He ignores her attempt to push him away, instead using his superior strength to press his body even more firmly against hers, pinning her small frame into the mattress. He continues to suckle hungrily, his mouth making wet, sucking sounds as he works his tongue around her swollen nipple, completely absorbed in the taste of her.
His hand, which had been wandering along her ribs, begins to slide lower. He doesn't stop at her waist; his palm glides down over the soft curve of her hip, moving with deliberate purpose. Beomgyu's breath catches when she feels his large hand slip beneath the elastic waistband of her panties.
"Soobin ah! What are you " Beomgyu gasps, her eyes widening in shock. Her heart hammers against her ribs like a trapped bird. "Stop, baby, that's not right! Don't touch there!" Her voice wavers between genuine alarm and a confused, terrified flutter of arousal that she desperately tries to suppress.
Soobin's fingers find their way past the soft fabric, brushing against the sensitive skin of her inner thigh before pressing against the damp heat between her legs. He doesn't stop there; his fingers explore the soft folds of her vulva, feeling how slick she has already become despite her protests. He pushes one finger past her vaginal lips, seeking the entrance to her small, pink cunt.
"Mommy is so warm..." Soobin mumbles against her breast, his words muffled by her flesh. He doesn't sound like a child asking for comfort anymore; his voice has dropped into something deeper, more possessive. "You're so wet for Soobin already, aren't you?"
Soobin's fingers find the slick entrance to her cunt, and he pushes one finger inside her with a slow, deliberate thrust. Beomgyu's entire body jolts at the intrusion, a sharp gasp escaping her lips. The sensation is overwhelming the combination of his warm mouth still latched onto her nipple and the invasive, stretching feeling of his finger inside her tight opening.
"Ah...! Soobin, please stop " Beomgyu cries out, but her protest lacks any real conviction. Her hips betray her, involuntarily bucking upward against his hand. The wetness she felt earlier has increased as her body responds to his touch, her own arousal flooding her vaginal lips. Her small, pink cunt clenches around his finger instinctively, milking him even as her mind screams that this is wrong.
Soobin doesn't stop. In fact, he becomes more brazen, using his thumb to circle her sensitive clitoris while his finger begins to pump rhythmically inside. The wet sounds of his penetration the squelching of his finger against her natural lubrication fill the quiet bedroom. "See, Mommy? You like it when Soobin touches you here," he murmurs against her skin, his breath hot and demanding. "You're so wet, your cunt is practically begging for me."
He withdraws his finger almost completely before plunging it back in deeper, stretching her sensitive walls. Beomgyu's head tosses back against the pillow, her eyes rolling back.
Her small breasts bounce slightly with each movement of his hand, and she feels helplessly trapped between her maternal instincts to protect him and the raw, forbidden pleasure spreading through her lower body.
Despite her panicked words and the moral conflict raging in her mind, Beomgyu's body has completely surrendered to the sensation. Every time Soobin's finger thrusts into her tight, pink cunt, a jolt of electricity shoots straight to her brain, making her toes curl beneath the sheets. The wet, squelching sounds of his finger sliding against her slick vaginal walls are intoxicating, filling her ears and making her feel utterly exposed.
"Ah... ahh! Soobin ah... mmmh..." Beomgyu's protests dissolve into incoherent, high pitched moans. Her hips have stopped trying to push him away and have instead begun to roll shamelessly against his hand, seeking more of that delicious friction. She arches her back, pressing breasts upward so that they rub against Soobin's face as he continues to suckle her nipples.
The stimulation of his thumb grinding against her swollen clitoris is almost too much to bear. She feels a building pressure between her thighs, a throbbing ache that demands release. "It feels... it feels too good... oh god..." she whimpers, her voice cracking. Her small frame trembles violently as she rides the waves of pleasure his fingers provide. She is completely lost in the feeling of being filled by her son's finger, her cunt clenching around him in desperate, rhythmic pulses.
"You're enjoying this so much, Mommy," he murmurs darkly, his voice vibrating against her sensitive nipple. "Look at how you're squeezing me. Your cunt is so greedy." He increases the speed of his thrusting, his finger pumping faster and deeper into her slick opening, driving Beomgyu closer and closer to the edge of a climax she knows she shouldn't want, but desperately craves.
Her breathing becomes short, shallow gasps, and her entire small body tenses like a bowstring.
"Soobin ah! Soobin ahhh! Oh god, wait ahhh!" Beomgyu cries out, her voice breaking into a high pitched, cute whimper as the climax crashes over her. Her vaginal walls begin to spasm uncontrollably around Soobin's finger, clenching and releasing in powerful pulses that seem to grip him with desperate strength. The intense pleasure shoots from her clitoris through her entire body, making her back arch violently off the mattress.
Her hips buck upward instinctively, grinding shamelessly against his hand as she rides out the waves of her orgasm. "Aah... ahh... mmmh!" she moans softly, her voice muffled by her own pleasure as she trembles from head to toe.
Suddenly Soobin moves away, leaving Beomgyu confused by the loss of contact. he shimmies down the bed just enough to free himself from his pants. The fabric slides down, revealing his massive, throbbing penis, already glistening with pre ejaculatory fluid. It stands tall and imposing in the dim light, a stark contrast to Beomgyu's small, delicate frame.
"Soobin ah... wait, please, you shouldn't... you shouldn't show Mommy that," she whispers, her voice cracking. She tries to pull the sheets up to cover herself, to create some semblance of modesty between them, but her limbs feel like lead.
Soobin shifts slightly, letting his hard, thick penis brush against her hip in a slow, soothing motion, like a cat seeking affection.
"I just want to be close to you, Mommy. Can't Soobin just stay like this? Can't we just love each other like this?" His eyes are wide and pleading, full of a childlike neediness that makes it nearly impossible for her to maintain her resolve. "Please, Mommy... don't be scared of Soobin. I'm still your baby boy. I just love you so much."
Beomgyu stares into Soobin's pleading eyes, her heart breaking at the raw vulnerability he displays. His words so sweet, so full of desperate love act like a poison to her moral defenses. The more he calls himself her 'baby boy' while his massive cock pulses inches from her thigh, the more her mind unravels. The conflict between her role as a mother and the overwhelming arousal coursing through her body becomes too much to bear.
A soft, shaky exhale escapes her lips as her resistance finally shatters.
"Oh, Soobin ah..." she whimpers, her voice cracking with surrender. "You're so bad... you're such a spoiled boy."
But she doesn't pull away. Instead, she reaches out with unsteady hands, her fingers brushing against his warm skin as she guides him closer.
The permission is unspoken but clear. Beomgyu's hips roll involuntarily toward him, her own cunt throbbing with a need that frightens her. The guilt is still there, a dull ache in the back of her mind, but it's being drowned out by the intoxicating heat spreading between her legs. She is so excited, so desperately turned on by his boldness and his sweet manipulation, that she can no longer say no.
"If... if it makes you feel better, baby," she whispers, her face flushing a deep crimson as she looks up at him through wet lashes. "If it helps you sleep..."
Beomgyu shifts her legs wider, parting them invitingly to give him access to her slick, swollen cunt.
Soobin moves between her legs with deliberate slowness, his large frame hovering over her delicate body. Beomgyu can feel the heat radiating off him, the tip of his massive, throbbing penis brushing against her sensitive vaginal lips.
He grabs her hips with his large hands, his fingers digging slightly into her soft flesh to anchor her in place. He positions the head of his cock at her entrance, the tip already slick with pre cum. "You're so wet for me, Mommy. Look how much you want Soobin's cock inside you." He doesn't wait for an answer. With one smooth, powerful thrust, he drives his entire length into her.
"Aahhh! Soobin ah! Oh god!" Beomgyu screams. The sensation of being impaled by something so thick and hot sends electricity through every nerve ending. Her small cunt struggles to accommodate his girth, her walls stretching painfully yet ecstasy inducing around him. The wet, slapping sound of their bodies meeting echoes in the quiet room as he bottoms out against her.
Soobin doesn't stop to let her adjust; he immediately begins to pump. His thrusts are deep, hard, and relentless, each one driving his cock deep into her womb.
"Mmmh, you're so tight, Mommy... you feel so good around Soobin's cock," he pants, his movements becoming faster and more primal. His hips slam against hers with bruising force, and Beomgyu can only moan in broken, high pitched whimpers as she rides the waves of overwhelming pleasure, her small body tossed about by his powerful strokes.
Soobin's thrusts become increasingly frantic as he nears his limit. His breathing comes in ragged, heavy gasps, each one echoing the primal rhythm of his hips slamming against Beomgyu's small frame. "Mommy... Mommy, I'm gonna I'm gonna cum so much for you!" he groans, his voice cracking with the strain of holding back.
Beomgyu is completely lost, her head tossing from side to side on the pillow, her small hands gripping Soobin's muscular shoulders as if she's afraid of drowning in the sensation. "
Ah! Ahh! Soobin ah! More... please, more!" she wails, her voice breaking into sweet, helpless whimpers. Her cunt is clenching around him like a vice, milking every inch of his length as she rides the edge of another climax, her body vibrating with every impact.
The wet, squelching sounds of their joined bodies fill the air as Soobin's pace becomes almost unbearable. He reaches down, one hand gripping her hip while the other finds her clitoris, grinding against it hard to push her over the edge. "Cum for me, Mommy! Cum for Soobin!" he commands hoarsely.
The combined stimulation is too much. Beomgyu's body stiffens, Beomgyu enjoys himself again, now on his son's penis.
That's when Soobin breaks. His entire body goes rigid, his muscles coiling like springs. "Mommy !" he gasps out, his voice dropping to a guttural moan. With several powerful, deep thrusts that seem to reach her very soul, he begins to cum. Thick jets of warm semen explode from his cock, flooding her tight cunt with overwhelming force. "Mmmph ahhh!" he moans softly but prettily, his eyes fluttering closed as he pours himself into her. The sheer volume is immense; Beomgyu can feel the hot liquid filling her up, pulsing deep inside her womb as he continues to pump wave after wave of cum into her body.
Soobin collapses against Beomgyu's small frame. His breathing is ragged and heavy, his chest rising and falling against her sensitive breasts as he tries to recover from the intensity of his climax. He stays buried deep inside her, his massive cock still twitching slightly as it continues to pump warm pulses of thick semen into her swollen cunt.
Beomgyu lies beneath him, completely boneless and spent. Her eyes are half lidded and glassy, staring at nothing as she tries to process the overwhelming flood of sensations. She can feel the heat of his cum pooling inside her, filling her small womb until she feels heavy and full. The wet, squelching sounds have faded, replaced by the soft, synchronized sounds of their labored breathing.
"Soobin ah..." she whispers breathlessly, her voice barely audible. The guilt hasn't vanished, but it has been dulled by the sheer exhaustion of her climax. She runs her weak fingers through his hair, a gesture that is both maternal and deeply intimate. "What happened that prevented you from sleeping?"
Soobin lifts his head slightly, pressing a soft, tender kiss to her forehead. His expression has returned to that of the sweet, devoted son, though his eyes still hold a dark glint of satisfaction. "I dreamt that you were marrying another man."
"That's not going to happen"
Soobin doesn't pull away. Instead, he shifts his weight to be more comfortable, still keeping his cock buried inside her slick, throbbing cunt. He wraps his arms around her small body, pulling her close so she can feel every inch of his heat.
"Stay like this with me? Please?" he asks in that same spoiled, needy tone. "Just let Soobin hold you while we sleep."
Beomgyu closes her eyes, letting out a long, shaky sigh. The feeling of him inside her is warm and comforting in a way that defies all reason. "Okay, baby," she breathes, her body finally relaxing completely into his embrace. "Just for tonight."
After a short while, they both actually fell asleep. Beomgyu drifts in a deep, exhausted slumber, her body still feeling heavy and pleasantly sore from their earlier encounter. But the peaceful silence is shattered when she suddenly gasps, her eyes snapping open as she feels a sharp, rhythmic intrusion between her thighs.
"Nnngh...! Ah! Soobin ah! What ahhh!" Beomgyu's voice breaks into a startled, high pitched whimper as she realizes she isn't alone. Her body is being moved, her hips being lifted and thrust back down with startling force.
Soobin has woken up again, but this time he isn't the sweet, sleepy boy. In the moonlight filtering through the curtains, she can see his silhouette broad shoulders and tensed muscles working in the dark. He has re entered her without any warning, his massive cock sliding back into her slick, swollen cunt with wet, slapping sounds that echo in the quiet room.
Beomgyu can't say how long he's been doing this. Just thinking about it actually excites her even more.
"Mommy... you're so warm..." Soobin murmurs darkly, his voice thick with renewed arousal. He isn't being gentle. His thrusts are deep and punishing, each one driving his cock all the way to her womb. "I couldn't sleep without feeling you again. I can't stop, Mom".
Beomgyu's heart hammers against her ribs in terror and confusion. "Soobin, stop! It's the middle of the night! Ahh! Nnngh!"
She tries to push against his chest, but he is too strong, pinning her small frame down against the mattress. The sensation of being fucked so suddenly, so aggressively while she was unconscious, sends waves of overwhelming sensation through her body.
Soobin's pace is relentless, his hips slamming against hers with a primal rhythm. "You like this, don't you? You like it when Soobin takes you like this, mommy," he pants hoarsely, his breath hot against her neck. "Your cunt is already getting so wet for me again..." The squelching sounds of his cock sliding through her natural lubrication fill the room as he drives her closer and closer to another terrifyingly intense climax.
Beomgyu is caught in a storm of conflicting sensations. The shock of being woken up by such intense penetration has her brain scrambling, but her body has already been conditioned to respond to him. "Ah! Ahh! Soobin ah! Too fast... it's too much! Nngh ahhh!" Her cries are high pitched and cute, broken gasps that escape her throat as she feels his thick cock stretching her sensitive walls to their absolute limit. Her small frame trembles violently under his superior strength, her breasts bouncing wildly as he pounds into her.
Soobin's breathing becomes ragged, his chest heaving against hers. "I'm cumming again, Mommy... I can't help it... I need to fill you up again!" His thrusts become shorter, faster, and more desperate as he nears his peak. "I love you so much... Mommy, Mommy, Mommy!" he whimpers in a way that is both possessive and needy.
"Ahh! Ahh! Soobin ah! I'm I'm going to ahhhh!" Beomgyu screams softly into the pillow as her orgasm crashes over her like a tidal wave. Her cunt clenches around him in powerful, milking spasms that seem to draw the very soul out of her. Her vision blurs as she rides the peak of her pleasure, her body convulsing beneath his.
Seconds later, Soobin follows her. His entire body locks up, his muscles coiling with terrifying intensity. "Mommy ahhh!" he gasps out, a sweet but strained moan escaping his lips. With several final, devastating thrusts that seem to impale her completely, he erupts. Hot, thick jets of semen explode from his cock, flooding her already slick cunt. "Mmmph... ahhh..." he moans softly, his head dropping to her shoulder as he pours wave after wave of cum deep inside her, filling her womb until she feels heavy and warm with his seed.
Beomgyu noticed that his stomach was swollen from the large amount of semen.
"I can't stop, Mommy," he murmurs, his voice dark and husky, stripped of its usual sweet innocence. "You feel too good. I need to stay inside you. I need to keep feeling how tight you are around Soobin."
"Soobin ah... baby," Beomgyu whispers breathlessly, reaching up to stroke his sweaty cheek. "Lie down properly for Mommy."
Soobin, still panting and riding the high of his climax, obeys immediately. He collapses backward onto the pillows, his large frame taking up most of the bed. His cock is still semi erect, slick and glistening with the overflow of cum that has leaked out of her cunt and onto his thighs. He watches her with wide, adoring eyes, like a puppy waiting for praise.
Beomgyu moves with surprising grace despite her trembling limbs. She crawls over him, straddling his hips. As she settles herself on top of him, her swollen cunt presses down against his lower belly, and she gasps at the sensation of her own wetness squelching between them.
"Nnngh... you really did make Mommy so messy," she giggles softly, a cute, airy sound.
She slides her ass down until her cunt is pressed firmly against his hard cock, feeling the heat of him through their joined skin. "Mmmh, you're still so hard for Mommy, aren't you?" she coos, leaning forward until her breasts press against his chest.
"Nnngh... ahh, it's so big, Soobin ah..." she whimpers as she slowly lowers herself down. She grinds her cunt directly over the head of his penis, forcing him to slide back into her heat. The sensation of being impaled again, combined with the slick squelch of her own overflow, makes her back arch involuntarily.
"Mmmph ahhh!" She gasps as she bottoms out on him, her small frame shuddering from the fullness. Her cunt clenches around him instinctively, milking his shaft as she settles completely onto his lap. The feeling of him filling her up again, after having been so thoroughly stuffed earlier, makes her brain turn to mush.
Maybe it's not so bad being like Soobin's sex doll. She can spend all day with Soobin's dick inside her.
Before he can even respond with words, Beomgyu leans forward, capturing his lips with hers. The kiss is deep, wet, and possessive. Her tongue slides against his, tasting the salt of his sweat and the lingering musk of their earlier coupling. It's a kiss that blurs the lines between motherly comfort and raw, unfiltered lust.
Soobin's hands grip her ass hard, his fingers digging into her soft flesh as he responds to the kiss with desperate hunger. "Mmmh... Mommy ahh..." he moans into her mouth, the sound muffled by their joined lips. He tilts his hips upward slightly, meeting her downstroke, making her cunt stretch even wider around him.
Beomgyu breaks the kiss just long enough to breathe, her lips glistening with saliva. "Kiss Mommy again, baby," she whispers breathlessly, before diving back in, her hips beginning to rock in slow, torturous circles atop his cock, making sure every inch of him feels the tight, wet embrace of her greedy cunt.
Soobin's hands slide from her ass up to her breasts. He kneads her possessively, his thumbs flicking over her sensitive nipples while his gaze fixes on her face with an intensity that borders on obsession.
"Mommy... ahh, Mommy..." Soobin moans into the kiss when they break apart, his voice dropping into a dark, needy register. His breathing comes in ragged gasps as he watches her flushed cheeks and swollen lips. "I can't stop thinking about it... about what you're carrying inside you right now."
Beomgyu blinks sleepily, her hips still moving in that torturous rhythm. "What are you talking about, baby? Mmmh..."
"I want to fill you up so much that you can't hold any more cum, and then... I want to make you pregnant, Mommy." The confession comes out raw and unfiltered, spoken with the terrifying sincerity of a child making a wish. "I want to put my baby inside your womb, so deep where only Soobin can reach."
Beomgyu's eyes widen, a gasp escaping her lips as she freezes mid grind. "Soobin ah! That's... ahh... that's too much..." But even as she protests, her body betrays her; the taboo nature of his words sends a fresh bolt of arousal straight to her clitoris.
"No, it's not enough!" Soobin growls, his hips bucking upward to thrust into her. "I want to see your breasts get bigger and heavier with my baby's milk. I want to wake up every morning and suck on them, Mommy. I want to drink your milk while you hold me and tell me how much you love me." His eyes grow glassy with lust. "I want to taste you like that forever..."
He nuzzles against her chest, his tongue darting out to lap at one of her nipples. "Mmmh, imagine it, Mommy... you so full of my cum, and then so full of my baby... and your milk flowing just for Soobin to drink." He looks up at her with those adoring, spoiled eyes. "Wouldn't that be perfect? Wouldn't you be the best Mommy ever if you let me do that?"
"Mmmh... you want to drink Mommy's milk? You want to be so close to me that we're one person?" she whispers, her voice thick with arousal as she continues to grind her cunt over his cock. "Such a greedy little boy..."
Soobin growls at her words, his hands sliding down from her breasts to grip her hips with bruising force. "I want everything, Mommy! I want your body, I want your womb, I want your milk!" His hips buck upward violently, sending his cock deep into her swollen cunt, making her cry out in a burst of pleasure. "I'm gonna fill you up so many times that you won't have any choice but to carry my baby."
He begins to thrust upward with devastating power, forcing Beomgyu to ride him with desperate rhythm. The sound of their bodies colliding the wet, squelching slap of her cunt against his pelvis fills the room.
"Nnngh! Ahh! Soobin ah! Faster! Ahh!"
The fantasy of being pregnant with his child, of her breasts swelling with milk just for him to suckle, sends her over the edge faster than anything before.
"Mmmh, Mommy's cunt is so tight around me when she thinks about it!" Soobin pants, his face flushed and sweat dripping from his brow. "It's sucking me so hard! Do you want it, Mommy? Do you want to feel my baby growing inside you while you feed me?" His thrusts become wilder, more uncontrolled as he nears another climax.
Beomgyu's orgasm crashes over her like a tidal wave. Her internal muscles spasm uncontrollably, clamping down on his cock in tight, milking waves that send Soobin over the cliff.
"Mommy! Ahh, fuck." Soobin roars, his own climax erupting with terrifying force. He thrusts one last time, burying himself to the hilt, as hot, thick jets of semen explode into her.
His body shakes with the intensity of it, each pulse of cum feeling like it's being driven directly into her womb, fulfilling his promise to fill her to the absolute brim.
The violent convulsions of Soobin's climax gradually subside, leaving his body heavy and boneless. Her head begins to rest on the pillow with a tired, sleepy expression.
Beomgyu remains perched atop him for several moments, her own body still quivering from the aftershocks of her orgasm. Her breath comes in shaky gasps as she stares down at her son's sleeping face.
"Soobin ah..." she whispers weakly, reaching down to brush a sweaty strand of hair from his forehead.
The physical reality of their coupling settles over her like a heavy blanket. Between her thighs, she feels the overwhelming sensation of being stuffed to capacity; his cock remains buried deep inside her, acting as a plug for the enormous volume of warm cum he has just pumped into her womb. Every time she shifts slightly, she can feel the liquid sloshing around inside her, a heavy, warm weight that makes her cunt feel bloated and tender.
"Mmmh... ahh..." she whines softly, a tiny sound of both pleasure and discomfort. The sheer amount of semen inside her is so great that she can feel it pressing against the walls of her cervix.
Despite the taboo of what they have done, and the terrifying implications of his words about pregnancy and milk, Beomgyu feels an overwhelming wave of maternal tenderness mixed with a deep, satisfied lust. She slowly lowers herself further onto him, not to fuck, but to simply lie against his warm chest. She wraps her arms around his broad shoulders, nuzzling into his neck just as he had done to her.
"Sleep well, my greedy baby," she murmurs against his skin, closing her eyes. "Mommy's right here." As she drifts off to sleep beside him, she can still feel the pulsing heat of his cum inside her, a constant, intimate reminder of the claim he has laid upon her body.
Soobin could finally relax knowing that his mother belonged to him. Your plan worked.
