Steven Universe is coming home from from collage when his gem powers start to act up. He has becoming incredibly horny, Pearl sensing some is wrong with him she triest to help only to become entrance and submissive to Steven while she is turned into a bimbo.

Chapter 4: Twin Offerings of Flesh

The air in the bedroom was thick and used, heavy with salt, sweat, and the coppery tang of spent desire. Steven stood over the ruin of the bed, his breathing slowing to a deep, resonant rhythm. He felt monumental. The soft light from the window painted the curves and valleys of his new physique, each muscle defined not for combat, but for a more intimate, crushing purpose.

Below him, the bed was a landscape of conquered flesh.

Ruby was already moving, a shiver of urgent need running through her plumped, compact form. Her hair, like a violent flame, stuck to her damp neck. She rolled onto her hands and knees, the motion causing the truly staggering expanse of her backside to wobble, a lush, pale orbit of fat and muscle that dominated her small frame. She looked back over her shoulder, her eyes wide and devoid of any complexity, burning only with a hungry, simple want.

“Do me,” she panted, her voice a rough, excited scratch. “Like that. From behind. I wanna feel it all.”

Beside her, Sapphire struggled. Her transformation had rendered her almost ludicrously unbalanced. Her breasts, each one larger than her head, were monstrously full, their weight anchoring her to the mattress. She pushed with her slender arms, trying to crawl, but the great, soft mounds dragged against the sheets, impediments of her own corrupted design. A faint, frustrated sound escaped her lips—not a sob, but the whine of a malfunctioning toy. Her single blue eye, peeking through her hair, was fixed on Steven not with sapphire prophecy, but with a dazed, bovine longing.

Pearl watched from the corner, curled in a nest of torn sheets. Her hand was between her legs again, moving in a frantic, automatic rhythm. “Yes, Steven,” she whispered, a broken record of devotion. “Show them. Show them how perfect it is.”

Amethyst just giggled, a low, wet sound. She lay on her back, playing with her own swollen stomach, tracing the outlines of the fullness Steven had left inside her.

Steven’s gaze swept over them. His compassion, his empathy—those were distant memories, echoes from a human boy who had lived in this room a lifetime ago. What he felt now was a profound sense of ownership. And a ravenous curiosity. His gem pulsed, a low, warm throb that resonated in his teeth. It was hungry. Not for food, but for completion. For more.

He ignored Sapphire’s struggling for a moment, his focus narrowing on Ruby. Her eagerness was a palpable heat. He placed a hand on the small of her back, and she arched into his touch like a cat, presenting herself further. The pink, bioluminescent light that clung to his skin transferred to hers, making her flesh glow faintly.

“You’re sure?” he asked, his voice a parody of his old concern. It was a game. They both knew the answer.

“Yes, yes, fuck, please,” Ruby babbled, pushing her hips back. “Need it. Need you to wreck me.”

He positioned himself behind her, his newly thick cock already rigid, jutting against the trembling swell of her ass. He rubbed the head through the wetness already slicking her folds, teasing, watching her whole body shudder. “You liked watching me use Garnet,” he murmured, not a question.

“Loved it,” she groaned, burying her face in the sheets. “Made me so hot. Saw how deep you went. Wanna feel that.”

He pushed in.

Ruby’s back bowed, a sharp cry tearing from her throat. He was thicker than before, the corruption refining his body for this singular function. She was impossibly tight, a fiery, clenching ring of resistance that made his vision spark. He filled her with a slow, inexorable pressure, stretching her to a breathless limit.

“Oh, stars,” she whimpered, her fingers clawing at the mattress.

He began to move, setting a brutal, pistoning rhythm from the start. There was no tenderness, only a driving need to possess, to imprint himself on her simplified consciousness. Each thrust slammed her forward, making the colossal flesh of her ass ripple in a chaotic, mesmerizing wave. The sound was obscenely wet, a sharp, rhythmic slap of skin on skin that drowned out the distant crash of the waves.

“Is it deep enough?” he grunted, his hands gripping the shelves of her hips, holding her in place for his use.

“Y-yes! So deep! More!” she screamed, her voice cracking.

He gave her more. He leaned over her, covering her smaller body, his chest against her back. The new power in his arms allowed him to lift her hips higher, angle her even more obscenely open. His pace became frenzied, animalistic. He was not making love to Ruby; he was erasing her, overwriting the last fragments of a warrior with the brute data of physical sensation.

Pearl’s whispering grew louder, a feverish chant. “Yes, perfect, so perfect, look at her take it, look at her become what you need…”

Sapphire had managed to crawl closer, her monstrous breasts dragging beside Ruby’s head. She stared, her single eye inches from the point where Steven’s body vanished into Ruby’s. Her mouth was slightly open, a thread of saliva connecting her lip to the sheet. She seemed hypnotized by the violent, rhythmic motion.

Her single eye was wide, unblinking, fixed on the junction of their bodies with a depthless absorption. A soft, continuous hum vibrated in her throat, harmonizing with the wet slaps of flesh. She was seeing nothing else, the entire universe narrowed to that brutal, penetrating rhythm.

Steven saw her staring. A new, jagged idea cut through the driving need to simply empty himself into Ruby. His power had split Garnet into her components. It had simplified them. What would happen if he pushed one of those components further? Past its breaking point? The curiosity was cold, clinical, and utterly compelling.

He abruptly pulled out of Ruby, leaving her gasping and empty on the bed.

“Wha—? Why’d you stop?” she whimpered, her voice ragged with unmet need. She looked back, her expression crumbling into confused hurt. “I was so close…”

“I know,” Steven said, his tone disturbingly gentle. He wrapped his hands around her waist. His grip was immense, his fingers nearly meeting around her midsection. He lifted her from the mattress as if she were made of straw.

Ruby let out a sharp yelp of surprise, her legs dangling. Her oversized ass, still glistening, jiggled with the motion. He turned her in the air, facing her away from him, and in one fluid movement, lowered her onto his waiting, upright cock.

She sank down with a choked cry, her body swallowing him whole in a single, breathtaking drop.

“Oh… oh, fuck…” she moaned, her head lolling back against his shoulder.

But he wasn’t finished. He adjusted his stance, knees slightly bent, and then he began to move her. Not with the driven, horizontal thrusts of before, but with a vertical, controlled force. He used the formidable strength in his arms and core to lift her almost completely off his length, her wetness making a soft, obscene sound as she rose, and then let her drop back down, skewering herself with her own weight.

He was using her body like a toy. A living, breathing fleshlight.

“Steven!” she shrieked, her voice a mix of shock and overwhelming sensation. Her hands flailed, finding nothing to hold onto but air.

He established a steady, bouncing rhythm. Up, then a heavy, gravity-driven downstroke that punched the air from her lungs. Up, then down. Each impactful reunion sent a shockwave through her soft, corrupted form. Her breasts jounced violently. Her ass slapped against his lower abdomen with a sound like a wet towel hitting tile.

Pearl’s chanting had stopped. She was silent now, her hand stilled between her legs, watching with parted lips. This was new. This was different from the frantic coupling with Garnet. This was a display of pure, unadulterated power, a demonstration that he could manipulate their very forms for his amusement.

Amethyst giggled again, nudging Sapphire. “Look, she’s like a bouncey ball.”

Sapphire didn’t respond. Her eye was still glued to the spectacle, her breathing shallow.

Steven’s face was a mask of intense concentration. He watched Ruby’s expression contort with each descent. He felt the incredible, silken heat of her constricting around him, the way her internal muscles fluttered helplessly with each brutal impact. The pink energy around his gem swirled faster, tendrils lashing out to wrap around Ruby’s glowing form.

“You feel that?” he growled into her ear, his breath hot. “Every drop. Every inch. Taking all of it.”

Ruby couldn’t speak. Her words had dissolved into keening, rhythmic wails that matched his tempo. Her eyes were rolled back, showing only whites. Her body was no longer her own; it was a vessel being operated by his will, a puppet of meat and desire. The overstimulation was total, short-circuiting every semblance of thought. Pleasure and a terrifying, rending pressure built inside her gem, a feedback loop with no release valve.

The bouncing became faster, harder. He wasn’t just letting her drop; he was actively driving her down now, adding his own upward thrust to meet her violent descent. The impacts became jarring, punishing.

“I’m—I’m gonna—” she tried to choke out, a warning without meaning.

“Do it,” Steven commanded, his voice guttural. “Let go.”

The climax that tore through Ruby was not a wave but a detonation. It was a silent, full-body convulsion that locked every muscle in a rigid arc. Her mouth opened in a soundless scream. Her gem, set in her fist, flashed with a catastrophic, blinding red light.

The pink energy surrounding her coalesced and surged inward, as if sucked into a vortex.

For a fraction of a second, her corporeal form held, vibrating at a frequency that hurt the eyes. Then, with a sound like a shattering lightbulb and a puff of rose-scented smoke, she was gone.

Steven’s hands closed on empty air.

A single, perfectly cut red gem clattered onto the wooden floorboards, rolling in a small, wobbly circle before coming to rest at the foot of the bed. It pulsed once, feebly, with a dim inner light, then went dormant.

The room was silent, save for Steven’s heavy breathing. He looked down at the gem on the floor, then at his own hands. A profound, unsettling satisfaction settled in his chest, cold and heavy. He had done that. He had fucked a consciousness right out of its physical form.

Pearl made a small, awed sound. “She… she couldn’t contain it. Your gift was too much for her.”

Steven stared at the inert red gem on the floorboards. The cold satisfaction in his chest was a new organ, pumping something darker than blood. He turned his head, the motion slow and deliberate, and his eyes found Sapphire. She hadn’t moved. Her single, wide eye was fixed on the spot where her other half had vanished.

“Where’d she go?” Sapphire whispered. Her voice was hollow, stripped of its usual chill premonition. It was just confused sound. Her massive breasts heaved as she breathed too fast.

“Somewhere simpler,” Steven said. His own voice sounded foreign to him, a calm and certain thing. He stepped over Ruby’s gem, his foot coming down with a soft thud beside it. The floorboard creaked. He stood before the bed, looking down at Sapphire’s struggling, top-heavy form. The pink energy around him reached for her like seeking vines. “She couldn’t handle the feeling. Can you?”

Sapphire’s eye finally lifted to his face. Then it dropped, dragged down by a helpless, gravitational pull, to his cock. It was still slick and glistening, jutting from the dense thatch of hair at his groin, utterly unashamed. It was the engine of all this change. She stared at it, mesmerized. Her plump, blue-tinted lips parted.

“I… I don’t know,” she breathed. But her body was betraying her. One of her soft, delicate hands, with its newly painted nails, crept from the sheets. It hovered in the air, trembling, halfway between recoil and invitation. “It looked… it felt like it was everything.”

“It is,” Pearl murmured from her corner, her voice a husk of its former precision. “It’s the only thing. Let it be your vision.”

Steven didn’t wait for permission. The concept was meaningless now. He closed the distance, the smell of sex and ozone and Sapphire’s strange, floral scent filling his nose. He gripped a handful of her silken blue hair, not painfully, but with absolute authority. He guided her head forward, off the edge of the mattress.

He brought his cock to her face.

The heat of it radiated against her cheek. She flinched, a tiny, instinctive thing, then stilled. Her eye, so close, crossed slightly trying to look at it. She could see the fine details, the pulsing vein, the pearly smear of Ruby’s residual essence at the tip. Her breath hitched, warming his skin.

“You saw what happened to her,” Steven said, his tone conversational, almost educational. He rubbed the broad head against her pursed lips, painting them with wetness. “That’s what happens when you take all of me. Do you want that?”

Sapphire’s mind, once a vast and crystalline lattice of possibilities, was a silent, empty chamber. The only data-point left was the overwhelming, muscular presence before her, and the memory of Ruby’s ecstatic dissolution. She had no future vision anymore. Only a terrible, hungry now.

Eager to feel that same thing that Ruby had, she opened her mouth.

Her tongue, cool and tentative, flicked out to taste him. A shudder wracked her exaggerated frame. Then, with a soft, desperate noise, she took him in. Her mouth was a tight, shocking coolness after Ruby’s furnace heat. She struggled at first, her lips straining around his girth, a gag reflex threatening. But the corruption within her adapted, softening her jaw, making her throat more supple. Her single eye rolled back, losing focus, as she concentrated on the physical truth filling her mouth.

She started to suck Steven’s cock with a frantic, graceless need. Her head bobbed, driven by a rhythm of pure want. One of her hands came up to cradle his heavy sac, her fingers kneading clumsily. The other hand gripped his muscular thigh for purchase. Muffled, wet sounds filled the room, punctuated by her choked, nasal breaths.

Steven looked down at the spectacle. The elegant, prophetic Sapphire was gone. In her place was a blue-haired blowjob doll, her face a mask of slobbering concentration, her ridiculous breasts crushed against the mattress. He thrust his hips slightly, feeding her another inch, and she took it, her throat fluttering around him. A low groan escaped him. The sensation was intense, but it was the power that intoxicated him. He had reduced a seer to a mouth.

“She understands,” Pearl cooed, her own fingers working faster. “She finally sees the only path.”

“Get deeper, ‘Phire,” Amethyst grunted, her own hand dipping between her legs again, mimicking the motion she saw.

Steven fisted his hands tighter in Sapphire’s hair, controlling the pace. He pushed deeper, feeling the head of his cock nudge the back of her throat. She gagged, tears springing from her single eye, tracing clean lines through the mess on her face. But she didn’t pull away. She pressed forward, impaling her own throat on him, a masochistic drive to experience the totality of his power, to chase Ruby’s fate.

Her gem, set in her palm where it was splayed on the bed, began to glow. Not its usual serene blue, but a frantic, flickering azure, shot through with threads of invasive pink. The feedback loop was closing. Her physical form was absorbing the corrupted energy directly from him, through the most intimate connection possible. Her sucking became more frantic, a drowning woman clinging to the very thing that was killing her.

He could feel it building—the same terrifying pressure that had shattered Ruby’s cohesion. It was a crescendo of sensation and impossible energy, a wave with no shore. Sapphire’s body began to vibrate, a high-frequency tremor that made her breasts quiver and her teeth chatter lightly against his flesh. A blue light, identical to the one that had consumed Ruby, started to seep from her pores, from the corners of her mouth stretched around him.

And still he fucked her face. And still she sucked.

The vibration became a violent shaking. The blue light blazed, suffusing the room. Sapphire’s eye locked onto his, and in its depths he saw no prophecy, no fear, only a final, staggering realization of completion.

With a final, brutal thrust that buried him to the hilt in her throat, he came.

It was the trigger. The overload was catastrophic.

Her form didn’t just poof. It flash-vaporized in a silent, concussive burst of indigo light and steam. One moment she was there, a warm, sucking pressure, and the next, Steven’s hands were empty, clutching only air. He stumbled back a step.

A perfect, blue gemstone dropped onto the rumpled sheets with a soft plink. It lay there, cool and silent, beside the impression her body had left in the mattress.

The room was utterly still. The only sounds were the distant ocean and the ragged draw of Steven’s breath. He looked at the two gems—red and blue—discarded on the floor and the bed. A matched set. Decommissioned.

Pearl was silent, her hand still between her legs, frozen. Amethyst had stopped giggling. She stared at the blue gem, her doughy face oddly blank.

Steven felt the energy coursing through him, unconsumed, seeking a new outlet. He turned his gaze, now alight with a hungry, pink-tinged intensity, toward the two remaining women in the room. His smile was not kind.

“Who,” he asked, his voice deceptively soft, “wants to be next?”

The silence that followed his question was thick, brittle, weighted with the absence of Ruby and Sapphire’s light. It was broken by a sharp, wet sob. Not from Amethyst, who stared with a dull fascination at her own swollen fingers, but from Pearl.

She unraveled from her corner.

Her movement was not the precise, birdlike motion he remembered, but a shuddering crawl. The elegant geometry of her limbs seemed softened, compromised. She crossed the space over the stained sheets, her eyes wide and liquid, fixed not on his face but on the floor beside his feet where the red gem lay dormant.

“She couldn’t… she couldn’t hold you,” Pearl whispered, her voice fraying at the edges. She stopped at the foot of the bed, her body folding downward until her forehead pressed against the wooden floorboards in a deep, abject bow. The line of her spine was a curve of total surrender. “I was wrong. Before. I tried to… guide. To control the feeling for you. I was a fool.”

Steven looked down at her. The pink pulse in his chest throbbed in slow, satisfied waves. This was new. This was better than rage or hunger. This was reverence.

“What are you now, Pearl?” he asked. He didn’t move.

“Nothing,” she breathed into the wood, her shoulders trembling. “A vessel. An empty space waiting to be filled by your will. My purpose… my only purpose… is to take whatever you give. To be shaped by it. To be broken by it, if that pleases you.”

She lifted her head. Tear tracks gleamed on her porcelain cheeks, but her expression was one of terrifying clarity. All her anxiety, her fastidiousness, her decades of layered neuroses had been burned away. Only a hollow, waiting devotion remained. “Use me. Please. Before I forget how to want it.”

Amethyst made a low sound in her throat, a cross between a groan and a laugh. “Whoa, P. You really just… gave up, huh?” She pushed herself up, her body rippling with the movement. “Kinda boring, just laying there. I’m not gonna beg.” She met Steven’s eyes, a spark of her old defiance lingering in the glazed blue. “But I’m not saying no, either. Just… do something interesting.”

Steven’s smile returned, colder. He appreciated Amethyst’s spark. It would make extinguishing it more satisfying. But first, Pearl.

“Show me,” he said to her.

Pearl understood. She rose to her knees, her movements now devoid of any performance, purely functional. Her hands went to the clasps and seams of her own altered form, the ridiculous corset, the stockings. She didn’t summon them away with light. She peeled the fabric from her body with a quiet, ritualistic care, as if unveiling something sacred. Each inch of revealed skin was offered, a silent testament.

Soon she was bare, kneeling on the hard floor. The afternoon light from the window cut across her, highlighting not the warrior nor the caretaker, but a stark, elegant template awaiting its sculptor. She was perfectly still, her hands resting on her thighs, palms up. Open. Empty.

“I submit,” she said, the words final, like a door closing. “Fully. There is no Pearl without your desire. Remake me.”

Steven stepped down from the bed. The boards were cool under his feet. He circled her, a predator assessing utter prey. His shadow passed over her, and she shivered, a flutter of her eyelids the only sign she felt it. He stopped behind her. With one hand, he gathered her long, pale hair and draped it over her left shoulder, exposing the delicate line of her neck and the prominent knobs of her spine.

“You watched me break them,” he murmured, his lips near her ear.

“Yes.”

“You want me to break you, too.”

“Yes.”

“But not like them,” he said, his fingers tracing a vertebra. “You don’t want to leave. You want to stay, and be empty for me. Forever.”

A full-body tremor wracked her. “Yes. Forever.”

He pushed her. Not hard, but with unmistakable command. She folded forward without a sound, catching herself on her hands, her back forming a graceful, arching line from her heels to her lowered head. The position was one of utter vulnerability, of presentation. She turned her face to the side, her cheek against the rough floorboard, her eyes squeezed shut.

From the bed, Amethyst watched, her breath coming quicker. She rubbed her thighs together.

Steven knelt behind Pearl. He didn’t enter her immediately. He traced the path with his fingers first, finding her dry, tight with a tension that was not resistance, but a held breath. The corrupted energy sparked from his fingertips, a soft, pink glow that seeped into her. Her body responded instantly, clenching then relaxing, preparing itself with a slick, willing heat that had nothing to do with organic arousal and everything to do with programmed response.

“Good,” he whispered.

When he pushed into her, it was with a single, slow, conquering thrust. There was no fight. Her body opened, a perfect, silken sheath calibrated to his exact dimensions. She made a sound then, a choked, guttural release of air, as if he had finally displaced the last ghost of her old self. He filled her completely, to the hilt, and then he was still, buried inside her, feeling the minute, fluttering pulses of her form around him.

This was nothing like the frantic, feedback-loop frenzy with Garnet, or the brutal overload that shattered Ruby and Sapphire. This was silent. Profound. A cold annexation.

He began to move. A slow, deep, piston stroke. Each withdrawal was almost complete, each advance a total reclamation. The sound was a soft, rhythmic shuffle of skin, his low grunts, the creak of the floor under his knees. Pearl was silent, her fingers splaying against the wood grain. Her entire consciousness seemed focused inward, on the feeling of being used exactly as she had begged to be.

“Look at her,” Steven said, his voice steady, commanding Amethyst’s attention. “This is what full submission looks like. No thoughts. No past. Just a function. A place for me.”

“Kinda hot,” Amethyst admitted, her voice husky. She slid off the bed, her heavy form landing with a soft thud. She crawled closer, drawn like a moth to the stark, fucking tableau. She lay on her side beside Pearl’s head, watching her face. Pearl’s eyes were open now, unfocused, gazing at nothing. A strand of drool connected her lip to the floor.

Steven’s pace remained measured, devastatingly controlled. He was not chasing his own climax. He was conducting a symphony of deconstruction. With each deep stroke, he pushed more than flesh. He pushed the pink energy, the corrupting data of his will, directly into the core of her being. Her gem, set in her forehead, began to glow, not with its own white light, but with a deep, pulsating rose.

“She’s changing,” Amethyst murmured, her own gem throbbing in sync.

Pearl was. The sharp, angular planes of her face seemed to soften, blurring at the edges. The intelligent sharpness in her eyes melted into a placid, depthless glaze. Her body, so tense with ready acceptance, began to lose its definition, becoming somehow simpler, more doll-like. She was not being physically reshaped like the others. She was being conceptually hollowed out. The meticulous, obsessive Pearl was being replaced by a static, worshipful Pearl-shaped void.

Steven felt the moment it finalized. A click in the feedback loop. A settling. Her internal flutters ceased, replaced by a uniform, warm pressure. Her breathing, which had been ragged, smoothed into a shallow, even rhythm. She was no longer participating. She was merely existing as a receptacle.

He allowed his own control to fracture then. The slow, deep strokes became faster, harder, driven by a final, rising wave of pure physical dominion. The floorboards protested. Pearl’s body rocked with the impacts, a limp, beautiful doll being wielded. Amethyst whimpered, her hand frantically working between her own legs, her eyes glued to where their bodies joined.

With a final, grinding thrust, Steven climaxed. It was a quiet, intense eruption, a flood of heat and intent pouring into the hollow vessel he had created. Pearl took it all without a sound, without a tremble. A perfect container.

He stayed inside her for a long moment, breathing heavily. Then he withdrew. Pearl remained on her hands and knees, head down, absolutely motionless. A trickle of fluid seeped from her onto the floor. Her gem’s glow faded to a soft, permanent pink.

“Pearl,” Steven said, his voice normal now. The deceptive softness was gone, replaced by casual ownership.

Slowly, mechanically, she sat back on her heels. She turned her placid, empty gaze up to him. A smile touched her lips. It was a sweet, vacant, utterly meaningless curve. “Yes, Steven?”

“Clean this up.” He gestured vaguely at the room, at the gems on the floor, at the soiled sheets.

“Of course,” she said, standing with a fluid, effortless motion. There was no hesitation, no residual emotion from what had just occurred. It was simply a new directive. She walked to the bathroom, her naked form moving with a blank elegance, and returned with a basin of water and a cloth. She began wiping the floor where she had knelt, humming a tuneless little song.

Steven turned to Amethyst, who was still panting on the floor, her hand soaked. The last spark of defiance in her eyes had been fanned into a different kind of fire—a desperate, competitive hunger. She had seen the absolute reduction of Pearl. She had seen the spectacular destruction of the others. A new, raw need twisted her features: the need to prove she could be the best, the most enduring, the most interesting toy.

“My turn,” she growled, pushing herself up onto all fours. “But not like her. I’m not gonna be some boring, empty cup.” She jutted her exaggerated backside toward him, a challenging, lurid offer. “Give me everything you got. I can take it. I won’t break. I’ll be better.”

Steven looked from Amethyst’s bravado to Pearl’s vacant, efficient cleaning, to the two dormant gems on his nightstand. The energy in him was a settled, deep-running current now, limitless and cold. He reached down and pulled Amethyst up by her hair, making her yelp. He pushed her against the wall beside the window, the ocean vast and indifferent behind her.

“Prove it,” he said.

Outside, the first long shadows of evening began to stretch across the beach, toward the temple, and the silent, sleeping town beyond.
