A arrogant and possessive demonic lord and a defiant yet caring glass incubus are in a relationship and bdsm master/slave and dom/bratty sub relationship, living in a modern fantasy world. The demonic lord, a hugely imposing and muscular figure, produces eggs from his cock, with edging causing more eggs to be produced in his balls. The eggs grow quickly, taking a day to grow hugely large, heavy, and spiky. The lord manages this by using the incubus as a breeding mount, fucking eggs into the incubus’s womb and reveling in the incubus’s erotic pleasure as the eggs grow. The incubus enjoys submitting and also enjoys teasing and edging the lord.

Chapter 3: Desperation

The office air, thick with the scent of old parchment and ozone, was severed by a ragged, broken sound. It wasn't a scream. It was the sound of a dam breaking.

Azazel’s fingers, a blur of cruel precision on Zephyr’s oversensitive clit, never ceased their rhythm. The pressure on his stomach, digging into the hard curve of an egg, never relented. The duality was perfect, engineered torture: a white-hot wire of pleasure pulled taut against a deep, sickening crush of pain. Zephyr’s body, strung between these two poles, finally snapped.

His back arched violently, a shockwave of pure, electric release tearing through him. It was less an orgasm and more a seizure of pleasure, a cataclysm that locked his glass joints and stole the air from his lungs. A silent, open-mouthed cry was all he could manage as the waves crashed over him, each peak higher than the last, making his internal energy flare in frantic, chaotic pulses behind his skin.

Azazel watched, his otherworldly eyes burning with satisfied intensity. He didn't stop. As the first devastating climax began to ebb, he increased the pressure, twisting his thumb over Zephyr’s clit with a ruthless, grinding motion. "There you go," he murmured, his voice a low vibration against the trembling quiet. "Now give me another. You're not done."

Zephyr couldn't speak. He could only feel. The descent never came. Instead, the sensation plateaued and then rocketed upward again, a second detonation triggered before the first had even faded. This one was sharper, brighter, a scream of nerve endings with no outlet. He came again, a broken, continuous shudder, his hips jerking mindlessly against Azazel's relentless hand. Fluids he didn't know he had left soaked the demon's fingers, dripping onto the polished floor.

It was during this second, overwhelming peak that his body rebelled in a new way.

A deep, involuntary clench seized his abdomen, a powerful muscular contraction that had nothing to do with pleasure. It started at the very core of his distended belly and rippled outward, a painful, rhythmic spasm. The eggs, huge and numerous, shifted violently inside him. His womb, overstretched and packed tight, tried to expel them. It was a primal, biological imperative, an urge deeper than thought.

His muscles bore down with all their weakened strength.

And met the unyielding obstruction of the vaginal plug.

The pain was blinding. The desperate, powerful contraction slammed the lowest egg against the hard, bulbous base of the bone plug wedged deep in his channel. It was like hitting a stone wall. A fresh, guttural cry was torn from Zephyr’s throat, mixed with the tail end of his orgasmic sobs. The contraction didn't stop; it pulsed, again and again, each wave a futile, agonizing push against the immovable object.

Each internal squeeze also compressed his colon, forcing the heavy, aphrodisiac-laced wine mixture deeper into his system. The liquid, with nowhere else to go, pressed upward, a sickening internal tide that made his already-full stomach feel fit to burst. He gagged, dry-heaving over Azazel's lap, the plugs in both holes holding everything inside with terrible, efficient cruelty.

"Look at you," Azazel said, his voice dripping with dark fascination. He finally removed his hand from Zephyr's clit, leaving the swollen nub throbbing in the cold air. He leaned forward, placing both palms flat on Zephyr's convulsing stomach, feeling the powerful, fruitless contractions ripple under his touch. "Your body knows what it needs to do. It wants to push these out. It's begging to."

He applied gentle, taunting pressure, matching the rhythm of Zephyr's straining muscles. "But you can't, can you? Not while I have you plugged up tight." He traced the outline of an egg, feeling it strain against the glass. "They're so ready. So heavy. Can you feel their spines? The sharp little ridges?"

Zephyr could only nod weakly, tears streaming down his face. He could feel them. Each egg wasn't smooth; they were textured with fine, abrasive ridges that scraped and chafed his inner walls with every painful contraction. They were a living, grinding weight inside him.

Azazel chuckled, a low, volcanic sound. "Good." He leaned back in his chair, studying Zephyr's ruined form. The incubus was a mess of trembling limbs, heaving stomach, and tear-streaked glass. "I think I'll keep you like this," he mused, as if discussing the weather. "Another day, maybe two. Let your body keep trying. Let these little fuckers get even bigger, even heavier. Let you ache and strain until you forget what it feels like to be empty."

The words should have been a death sentence. A promise of unending torment. Yet, as they sank into Zephyr's pleasure-frayed mind, they ignited something else. A dark, masochistic spark deep in his gut. The thought of being trapped in this state, full to breaking, perpetually on the edge of a release his body was violently denied… it sent a shocking, shameful bolt of arousal straight through the pain.

Another low moan, different in tone, spilled from his lips. This one was soaked in submission, in a twisted kind of want.

Azazel heard it. His glowing eyes flared. "You like that idea, don't you, you filthy little thing?" He didn't touch him again. He just let the concept hang in the air, let Zephyr marinate in the horrifying, erotic prospect. "You want to be my full-time broodmare, don't you? Stuffed and sealed and useless for anything but carrying my clutch."

Zephyr’s body answered for him. The heavy, spiky eggs inside him seemed to pulse in time with his quickening heartbeat. His incubus energy, usually a calm flow, flared in a sudden, brilliant cascade of light behind his glass skin, responding to the intense cocktail of agony, humiliation, and dark arousal. It wasn't a release of power; it was a visible fracture of his control, a bioluminescent betrayal.

And with that flare of energy came a third, devastating orgasm.

It rolled through him without a single touch, triggered purely by the psychological horror and the physical reality of his predicament. It was a deep, convulsive clenching that made his vision tunnel to a pinprick of dark pleasure amidst the pain. He slumped forward, his forehead hitting the edge of the desk, his body wracked with silent, continuous tremors as the last waves of forced ecstasy milked him dry.

Azazel watched the final shudders pass through his incubus. A slow, possessive smile spread across his features. He ran a clawed hand through Zephyr's damp hair. "Tomorrow," he whispered, the word a promise and a threat. "We'll see if you can take another day of this."

He stood up, leaving Zephyr kneeling, broken and pulsing with stolen pleasure, on the cold floor. The chapter of torment was over, for now. The next was already written in the painful, eager clench of Zephyr's body, still plugged, still full, and utterly, completely owned.

The next was already written in the painful, eager clench of Zephyr's body, still plugged, still full, and utterly, completely owned. Azazel left him there, kneeling in a puddle of his own slick and sweat, for what felt like hours. Time blurred into a haze of discomfort, a constant, low-grade agony centered in the impossible weight of his stomach and the relentless, dull ache of being stretched and stuffed at both entrances. He drifted in and out of a jagged consciousness, each return to awareness a fresh confrontation with his reality.

The contractions began as sporadic, deep tremors. A sudden, internal cinching that would steal his breath, make his vision spark, and then subside. They were far apart at first. He could count the slow breaths between them. Each one was a brutal, full-body squeeze, the spiky eggs grinding against his inner walls, the plugs holding firm like monstrous teeth. Each squeeze also forced a fresh trickle of arousal from his tortured flesh, a humiliating leak that cooled on his thighs.

He lost track of day and night in the windowless office. Azazel returned, not with comfort, but with purpose. He would work at his desk, scrutinizing scrolls, while a single, booted foot would find its way between Zephyr’s legs, pressing insistently against his swollen clit. “Your body’s working,” Azazel would say, not looking up from a parchment. “I can feel it tightening. Trying so hard to be useful.”

The intervals between the clenches shortened. Twenty minutes. Then fifteen. The pain intensified, a deep, bone-deep cramping that started in his womb and radiated out to the very tips of his glass fingers. But woven through the pain, amplified by the lingering aphrodisiac still in his system, was a sharp, undeniable spike of pleasure. His nerves, overloaded and frayed, could no longer distinguish between suffering and sensation. A contraction would hit, a vise-grip of agony, and his cunt would pulse around the plug, his back would arch, and a weak, shuddering climax would ripple through him.

“Fuck,” he’d gasp into the floor, nails scraping stone. “Oh, fuck, no…”

Azazel would chuckle, the sound warm and dark. “Yes. That’s it. Let me see.”

He’d pull Zephyr up by the hair, forcing him to stand on wobbling legs. “Walk for me. Let’s see how you manage.” Zephyr would stumble a few steps, each movement jostling the infernal weights inside him. A contraction would seize him mid-step, buckling his knees. Pleasure-pain would lance through him, and he’d come again, a broken, gasping thing, supported only by Azazel’s grip in his hair.

“Pathetic,” Azazel would coo, lowering him back to the floor only to force him up again moments later. It became a cruel game. Stand. Stumble. Be seized by a racking, internal convulsion that tore a ragged moan and a petty orgasm from him. Collapse. Repeat.

The contractions closed in. Ten minutes. Then five. They were relentless now, a physiological tyranny. His body was no longer his own; it was a battlefield, a factory, a fuck-toy. He was slick constantly, a mixture of his own desperate juices and the oily residue of the plugs. His stomach was a monument to strain, the glass skin stretched so taut it shone, the shadows of the spined eggs clearly visible beneath the surface.

During one vicious stand-up exercise, a contraction hit him like a physical blow. It wasn’t a wave; it was a tsunami. His legs simply gave out, bone-deep cramps locking his joints. He crumpled forward, a marionette with cut strings, catching himself on his hands before his swollen belly hit the stone. He knelt there, head hanging, saliva dripping from his lips, his entire frame trembling with the after-shocks of the climax that had ridden the contraction’s crest.

Azazel loomed over him. The demon’s scent, ozone and musk, filled Zephyr’s nose. He could see the thick, heavy line of Azazel’s cock, half-hard already, against his thigh. A new, desperate need cut through the fog of pain and forced pleasure. A need to please, to appease, to somehow gain a fraction of control in this unraveling world.

With a whimper that was half-sob, half-supplication, Zephyr dragged himself forward on his knees. He fumbled with the ties of Azazel’s trousers, his fingers clumsy and shaking. Another contraction began to build, a deep, tightening dread in his gut.

“No, no, not yet,” he begged his own body, desperate to complete this one act.

He freed Azazel’s cock. It sprang out, fully erect, an imposing thickness that tasted of salt and power. He didn’t hesitate. He took the head into his mouth, his tongue swirling over the slit, tasting the bitter pre-come. He worked to take more, his jaw straining, as the contraction reached its peak.

It blindsided him. The pain was a white-hot ring of pressure around the eggs. The concurrent orgasm was a violent, full-bodied spasm. His mouth went slack around Azazel’s cock as his back arched, a silent scream tearing through him. He rode it out, shuddering, tears of frustration leaking from his clenched eyes.

When it passed, leaving him hollow and gasping, he remembered his task. He sucked in a ragged breath, saliva slicking his chin, and took Azazel back into his mouth. He bobbed his head, a clumsy, rhythmless motion. He was a mess, his focus shattered, his world reduced to the pounding in his belly and the heavy weight on his tongue.

Another contraction gathered, faster now, maybe three minutes since the last. He whimpered around the shaft, redoubling his efforts. He licked and sucked, hollowing his cheeks, trying to be good, trying to be anything other than a broken vessel.

The cramp seized him mid-suck. His jaw clenched involuntarily, his teeth scraping the sensitive skin. Azazel grunted, not in pain, but in dark amusement. “Careful,” he rumbled, his hand coming down to cradle Zephyr’s head, not gently, but with ownership.

Zephyr couldn’t answer. Pleasure detonated along his nerves, his cunt clenching violently around the plug, his ass tightening on the stone one. He came again, his throat working around Azazel’s cock, his nose pressed into the demon’s rough pubic hair. The sensations overlapped, merged: the taste of skin, the smell of musk, the crushing internal pressure, the bright, shameful fire of release.

He came back to himself, still sucking, still trying. A thin, continuous moan vibrated against Azazel’s flesh. He was a thing of function now, a mouth servicing, a body endlessly convulsing, a mind dissolving into a raw, singular need to fulfill this last, desperate purpose before the next wave of his own treacherous biology took him under again.
