2~6

A few days after the birth of his son, Julian fell into a routine of changing diapers and burping his son in-between allowing his wife to breastfeed the boy.

"I'd say the young master is quite healthy, Duke Julian."

The visiting doctor spoke freely to Julian.

"Good... he was born so fast, I had initially worried he'd be ill."

Julian murmured, cradling his son closely and rubbing the small fuzz of wispy white hair in the infant's head.

The doctor chuckled, a warm, reassuring sound.

"He's a strong little one, it's been quite some time since I've encountered a child born of a human and demon. His mana is developing nicely. It resonates with a power I haven't encountered before - stunning and warm."

The doctor relayed as Julian grinned broadly down at his sleeping son affectionately.

Once the doctor left, Julian slowly strode into his wife's room, his gaze falling to her milk swollen breasts and subtle strands of silvery gray beginning to streak through her blue hair once again. If she didn't feed on sexual energy sometimes soon, she'd likely revert to the decrepid old hag he'd first married - though it would serve her right in Julian's opinion.

"The doctor has given him passing marks with flying colours."

He mentioned, sitting at the edge of Zefeni's bed.

Zefeni’s golden eyes flickered open, a languid smile gracing her lips. She stretched, a slow, deliberate movement that showcased the curves of her body, even more pronounced now after the birth.

“How… comforting.”

She purred, her voice a silken rasp.

“Though I suspected as much. My lineage doesn’t produce weaklings, even with a human stud.”

Her gaze swept over Julian, lingering on his face with a possessive intensity.

“And you, my Duke, seem quite taken with our son.”

"I've decided on his name."

Julian mentioned. It had taken him a few days to decide, but the wait had been well worth it.

Zefeni raised a perfectly sculpted eyebrow, her expression a carefully crafted mask of polite interest.

“Oh? And what name have you chosen for your heir, my love?”

Her voice dripped with a subtle challenge, a silent assessment of Julian’s decision-making capabilities on his own. She idly stroked the silken sheets with a well manicured finger, her golden eyes never leaving his.

"Athan... it means eternal life in one of the tongues of my past life..."

Julian murmured as his sons eyes cracked open sleepily, revealing green orbs a few shades lighter than his own - but still green nonetheless.

A flicker of something unreadable crossed Zefeni's face - a shadow that vanished as quickly as it appeared.

“Athan.”

She repeated, testing the weight of the name on her tongue.

“Eternal life… ambitious. Fitting, perhaps, for a child destined for greatness - but what he needs are strong brothers and sisters to support him, to support you as their father."

She purred suggestively, running a hand over Julian's flaccid crotch.

Julian stiffened, his jaw tightening. He hadn’t anticipated such a blatant advance so soon after the birth. He carefully extracted himself from her grasp by standing up and moving away from her bed.

"I do not desire anymore children. At least not with you."

He said coldly.

Zefeni’s laughter was a chilling sound, devoid of warmth. It echoed in the opulent chamber, bouncing off the silk draperies and polished surfaces.

“Oh, my dear Julian.”

She said, her voice dangerously soft.

“You wound me. Do you truly believe you have a choice in the matter? You are bound to me, body and soul. Our lineage requires heirs.”

She rose from the bed, her movements fluid and graceful, despite the recent childbirth. She was clad in a sheer nightgown, revealing glimpses of her still-healing form.

He set Athan down carefully in his bassinet and then turned toward Zefeni - the back of his hand snapping across her face audibly.

"I've told you already. Fix your ways."

The sound of the slap reverberated through the room, momentarily silencing Zefeni. A crimson handprint bloomed on her cheek, stark against her porcelain skin. Her golden eyes narrowed, blazing with a fury that sent a shiver down the spine. But she didn’t retaliate physically. Instead, a dark energy began to coalesce around her, swirling like a tempest - but simmered down as she felt Julian's cold eyes boring into her own.

Zefeni inhaled deeply, visibly struggling to regain control. The dark energy receded, leaving behind a lingering scent of ozone and something ancient, something unsettling. She brought a delicate hand to her stinging cheek, her gaze fixed on Julian with a mixture of shock and simmering rage - but oddly also some sort of respect in his manner of controlling her.

"If you want fed, you will behave."

Julian was practically the only thing keeping her from starving now. She needed his life essence through sex to feed her succubus habits.

A slow, predatory smile spread across Zefeni’s lips, replacing the earlier fury with a dangerous allure. She approached Julian with deliberate steps, her eyes locked on his, radiating a challenge.

“Such… discipline.”

She murmured, her voice a silken whisper that sent a shiver down Julian’s spine despite his attempts at stoicism. She stopped mere inches from him, her body close enough that he could feel the heat radiating from her skin.

“You truly believe you can control me, Duke?”

She reached up, her fingers tracing the line of his jaw with a feather-light touch. Julian remained rigidly still, his gaze unwavering, refusing to betray any reaction to her proximity.

He closed a hand gently around her wrist and pulled her close so she could feel his bulging erection straining through his trousers.

"I don't need to control you if your starving for me. Your life depends on my seed. So you'll just do what you have to."

He whispered.

Zefeni’s breath hitched, her golden eyes widening slightly as Julian’s hand closed around her wrist, drawing her into his embrace. The blatant display of his arousal, the raw power radiating from his body, was a deliberate provocation - and it worked. A flush crept up her neck, colouring her cheeks a delicate rose.

"Open."

He growled huskily, tracing his thumb lightly across her bottom lip.

A tremor ran through Zefeni’s body, and she found herself unable to resist the primal command in his voice. Her lips parted slightly, revealing a glimpse of sharp, pearly teeth. The surrender was a humiliation, but also… a surprising thrill. A dangerous spark ignited within her, a flicker of the succubus she was, **** for release, **** for him. She leaned into his touch, her gaze locked on his, a silent invitation.

Julian's lips covered hers, his tongue pressing into her mouth sensually, dominating hers with a slow and heavy kiss. He withdrew before she could fully enjoy it though.

Zefeni gasped softly as Julian’s lips met hers, the initial pressure both shocking and exhilarating. She instinctively tried to deepen the kiss, to take control, but Julian’s abrupt withdrawal left her breathless and frustrated. Her fingers clenched into fists at her sides, her nails digging into her palms. The tantalizing tease ignited a burning desire within her, a **** need for more. She stared at him, her golden eyes narrowed, a silent question hanging in the air.

He exhaled through his nose, letting go of her and turning away.

"We'll try again tomorrow when you stop trying to take control."

Zefeni’s jaw tightened, her knuckles white as she fought to contain her rage. The blatant rejection, the assertion of dominance, was infuriating - but she couldn’t deny the thrill of being challenged, of being brought to the edge of her control. She watched Julian turn away, her gaze following the rigid line of his back. A slow smile curved her lips, a dangerous glint in her golden eyes.

The next day, Julian returned as promised. He watched intently from across the room as Athan nursed at Zefeni's milk heavy breast.

Zefeni didn’t acknowledge Julian’s presence, her focus entirely on their son. She held Athan close, her expression a mixture of tenderness and possessiveness. Her lips curved into a soft smile as Athan suckled contentedly, her golden eyes occasionally glancing down at his face. The scene was domestic, almost peaceful - a stark contrast to the power dynamics that simmered beneath the surface. She continued to nurse Athan, her gaze occasionally flickering towards Julian, assessing his reaction, gauging his patience.

Once Athan has drank his fill and been placed back in his bassinet, Julian looked over at his wife expectantly. He knew how hungry she was for life energy to feed on - but she would not be recieving it without obedience.

"Take off your clothes."

Zefeni’s lips tilted in a slow, knowing smile. She didn’t flinch at his command, didn’t offer a protest. Instead, she met his gaze with a challenging intensity, her golden eyes brimming with a dangerous allure. She slowly unfastened the delicate buttons of her nightgown, her movements deliberate and unhurried, savoring the anticipation. As the silk slipped from her shoulders, revealing the pale curve of her breasts and the smooth expanse of her skin, she raised an eyebrow, a silent question in her eyes.

“Is that all, my Duke?”

He kicked a bucket with odd pieces in it towards her.

"Hook those cups up to your breasts."

Selfishly, Julian had experimented with some blacksmithing these last few days, mimicking the breast pumps that usually go onto cows in his old world. With the aid of a magic stone, he could achieve the same thing in this world. He planned on teaching his wife to be an obedient wife and milk cow.

Zefeni’s eyes narrowed, a flicker of disbelief crossing her features as she took in the strange contraption Julian had created. The metal cups, connected by tubes and powered by a glowing stone, were a crude imitation of the natural intimacy she craved. A slow flush crept up her neck, her cheeks burning with a mixture of humiliation and indignation. But she didn’t refuse. She knew better than to defy him outright. With a graceful, yet resentful movement, she picked up the device and began to attach the cups to her breasts, her golden eyes fixed on Julian with a simmering fury.

“You… enjoy this, don’t you?”

She hissed, her voice barely a whisper.

“Humiliating me.”

Julian remained impassive, watching as Zefeni reluctantly complied with his command. He didn’t offer a word of explanation, didn’t attempt to soothe her wounded pride. His gaze was cold and calculating, assessing her reaction, gauging the extent of his control. As the magical stone hummed to life, drawing the nourishing creamy milk from her breasts into the tubes, a visible shudder ran through Zefeni’s body. Her knuckles clenched, her jaw tight, but she didn't resist. The process was undeniably degrading, reducing her to a mere vessel for Julian’s desires.

Julian watched, his expression unreadable, as the tubes filled with her demonic milk – Zefeni’s creamy delight carefully extracted and contained. He observed the subtle flush of colour darkening on her cheeks, the slight slumping of her posture. It wasn’t about the milk itself, though he knew its potent magical properties would benefit him. It was about the power dynamic, the complete and utter subjugation of a powerful demon to his will.

Julian finally stood up, circling her and tracing his fingertips down the dip of her back before grabbing her whip-like tail and giving it a firm yank.

Zefeni gasped, a sharp intake of breath as Julian’s fingers traced the sensitive skin of her back. The sensation was unexpectedly pleasurable, sending a shiver down her spine. But the momentary pleasure was shattered as his hand closed around her tail, the firm yank sending a jolt of pain through her body. Her eyes flashed with fury, her lips curling into a snarl. She instinctively arched her back, her claws extending, but she held back from retaliating, knowing full well the consequences of disobedience. A low growl rumbled in her chest, a warning to Julian that she was reaching her limit.

“You dare…”

She began, her voice laced with venom, but she stopped short, biting back the rest of her words.

"I don't believe I asked you to speak. Right now you are no more than a cow. Be silent."

His hand connected with her ass in a forceful slap.

A strangled cry escaped Zefeni’s lips as Julian’s hand connected with her ass, the **** of the blow sending a searing pain radiating through her body. Her eyes blazed with rage, her body trembling with suppressed fury. She bit down hard on her tongue, refusing to utter a sound, determined to maintain a semblance of control. The humiliation was excruciating, the degradation complete. She lowered her head, her long hair cascading over her shoulders, obscuring her face. But beneath the veil of hair, her golden eyes burned with a cold, calculating fury. She would remember this. She would repay him. But for now, she would endure. She would be silent. She would be a cow.

A tremor ran through Zefeni’s body, a complex mixture of shame, rage, and a forbidden arousal. The rhythmic pulsing of the milking device, the sensation of her breasts being drawn and emptied, was undeniably stimulating. A slickness began to build between her legs, a betraying response to Julian’s cruelty. Her breath hitched in her throat, her body arching slightly as the pleasure intensified. She squeezed her eyes shut, desperately trying to regain control, to suppress the rising tide of desire. But it was no use. Julian had broken through her defenses, exploiting her deepest vulnerabilities, turning her own body against her. A soft moan escaped her lips, quickly stifled, but Julian undoubtedly heard it. She was losing herself, succumbing to the perverse pleasure of his dominance.

Zefeni’s eyes snapped open, her gaze locking onto Julian as he began to unfasten his trousers. A wave of panic washed over her, quickly followed by a surge of anticipation. The brazen audacity of his actions, the complete disregard for her dignity, was both terrifying and intoxicating. Her heart hammered against her ribs, her breath coming in ragged gasps. She tried to look away, to shield herself from the inevitable, but her eyes were drawn to him, captivated by the slow, deliberate movements of his hands. A whimper escaped her lips, a sound of both protest and surrender. She was trapped, completely at his mercy, and a part of her, a dark and forbidden part, was beginning to enjoy it. He may not realize it but he was the one becoming the perfect perverse Duke in her darkest desires.

Julian teased the tip of his bulbous cock between her drooling wet folds, torturing her further. He knew how badly she wanted it - but he was the one controlling the pace.

A strangled gasp tore from Zefeni’s throat as Julian’s cock brushed against her swollen folds. The sensation was exquisite, excruciating, sending a shockwave of pleasure through her entire body. Her muscles clenched involuntarily, her nails digging into the hardwood floors. She arched her back, **** for more, but Julian held back, teasing her, prolonging her torment. A low moan escaped her lips, a sound of pure desperation. She was completely lost, consumed by a desire she couldn’t control. Her eyes fluttered shut, her body trembling as she surrendered to the exquisite ****.

“Please…”

She breathed, the word barely audible, a plea for release. But Julian remained unmoved, a cruel smile playing on his lips. He was the master, and she was his plaything.

"Please what?"

Julian growled huskily, spreading her folds with just a kiss of the tip before withdrawing again.

Zefeni’s breath hitched, her body spasming with frustration as Julian teased her again, the briefest touch sending her spiraling towards the edge of oblivion. Her golden eyes fluttered open, filled with a **** longing. She swallowed hard, her throat dry and aching.

“Please… finish me.”

She finally whispered, the words laced with shame and a **** need. Her voice was barely a breath, a broken plea from a demon stripped of her power and reduced to a whimpering supplicant. She could feel the heat building within her, the pressure mounting, threatening to overwhelm her. Every nerve ending screamed for release, for the sweet relief of oblivion. But Julian held the power, and she was entirely at his mercy.

"Oh yeah? Is that truly what you want?"

He lightly thread his fingers through her light blue hair, giving it a firm tug to pull her head back some.

Zefeni’s head snapped back with the **** of Julian’s tug, a sharp cry escaping her lips. Her eyes met his, burning with a mixture of fury and surrender. She didn’t flinch, didn’t resist, but her body trembled with anticipation.

“Yes.”

She breathed, her voice raspy and raw.

“I want you to break me. To claim me. To finish me.”

The words were a confession, a surrender of her will, a testament to the power he held over her. She lowered her chin, exposing the delicate curve of her throat, offering herself to him completely. Every inch of her body ached with desire, begging for his touch. She was a demon, a creature of immense power, yet she was reduced to a trembling, **** mess, utterly at the mercy of the man who held her captive.

Julian let go of her hair and slammed his hips forward brutally - forcing his cock deep into her ass 'by accident'.

"Wrong hole?"

He shrugged indifferently.

A strangled scream ripped from Zefeni’s throat as Julian’s cock slammed into her ass, the brutal **** tearing through her defenses. Pain exploded within her, a searing, overwhelming sensation that threatened to consume her. Her body arched violently, her claws digging into the floor, **** for purchase. But there was no escape. He was inside her, deep within her most **** core, and the violation was complete.

His hand closed around her throat as he ground himself nice and deep against her wobbling asscheeks. He leaned in closely and whispered against her ear in a low hiss.

"Give me your 'true' name succubus Zefeni."

He ordered - taking advantage of her **** state.

Zefeni choked, her hands clawing at Julian’s arm, desperately trying to loosen his grip. The pressure on her throat was immense, cutting off her air supply, adding to the exquisite torment of his intrusion. Her vision blurred, her body trembling with a mixture of pain, pleasure, and terror. But she refused to break, refusing to give him the satisfaction of seeing her submit completely.

"Your name!"

He commanded again, thrusting his hips roughly into her.

A strangled gasp escaped Zefeni’s lips as Julian’s forceful thrust sent a searing wave of pain through her. Her lungs burned, her vision darkening at the edges. She fought against the rising panic, against the urge to simply surrender. But the pressure on her throat was relentless, and Julian’s demand echoed in her ears, a cruel and insistent command. Her resolve began to crumble, her carefully constructed defenses weakening under his relentless ****.

A tremor ran through Zefeni’s body, a sign of her weakening resistance. Her golden eyes, wide with a mixture of fear and desperation, flickered with a hint of defeat. She knew she couldn't hold out much longer. The pain, the humiliation, the suffocating pressure on her throat – it was all becoming too much.

A single tear traced a path down Zefeni’s cheek, a testament to her crumbling pride. Her lips parted slightly, and a strangled whisper escaped her throat.

“Izayoi…”

She finally rasped, the word barely audible. It was her true demonic name, the name that gave whoever knew of it, power over her. The moment her name left her lips, a black runic collar engraved around her neck, enslaving her to her husband's will.

A cruel smirk twisted Julian’s lips as he heard the whispered name. Izayoi. The power that surged through him upon hearing it was intoxicating, a dark and heady rush that solidified his control over the demon before him. He tightened his grip on her throat, reveling in her vulnerability. The runic collar around her neck glowed with an eerie, black light, binding her to his will, sealing her fate.

"I believe this marriage will be more beneficial to me from here on out. As it should've been from the beginning."

Julian murmured, letting go of her throat and pulling slowly out of her ass. His erection throbbed a couple of times before his seed shot out across her voluptuous ass.

Zefeni lay gasping on the floor, her body trembling with exhaustion and humiliation. The release of pressure on her throat was a welcome relief, but the burning sensation in her core, coupled with the shame of her **** surrender, was almost unbearable. She watched, powerless, as Julian withdrew, his seed spilling across her ass, a final act of dominance and degradation. Her eyes, once blazing with demonic fire, were now clouded with despair. She was being trained by a human, utterly and completely at his mercy. A whimper escaped her lips, a sound of utter defeat.

Julian stood over her, his chest heaving, a cold satisfaction hardening his features. He didn’t offer a hand, didn’t offer a word of comfort. He simply watched her writhe, a predator surveying his conquered prey. The air hung thick with the scent of sex and submission.

"From here on out, you will respect me both behind closed doors and in public. You will be a supportive and loving wife, as well as nurturing mother to our son. If you disobey, I will send word of your transgressions to the kingdom - and you'll lose you're standing among the nobility."

Zefeni’s body stilled, her eyes locking onto Julian’s with a newfound intensity. The humiliation and pain had been replaced by a simmering rage, but it was a rage tempered by the realization of her new reality. She was bound to him, enslaved by her own true demon name and the power he now wielded over her. She knew challenging him directly would be futile.

"As you wish..."
