Chapter 4 Oppai Is Justice, Flat Is Vengeance
Issei crashes into a hot spring after pissing off Great Red, gets pinned by a breastless swordswoman, and accidentally brings her tits back with Boost. Now his dream of becoming Harem King is no longer a joke.
The village nestled in the folds of green hills, but instead of the rowdy cacophony of the countryside, only silence pressed down.
Each home leaned on sagging beams as if waiting to collapse. Doors stayed shut even in daylight. No scent of cooking rice drifted on the wind. No smoke rose from family kitchens. The silence clung like mist, heavy with grief.
Kaede was not with them. She had slipped away the night Issei loosened her ropes. He wasn't sure if he'd freed her… or if she'd used him to slip the ropes. Ouka had said nothing then. She said it now.
"You untied our prisoner, boy. You let your cock guide your hand. Now she runs free while you slept like a dog after rutting like one."
Issei flushed but forced words out. "I was only helping her. She looked miserable, tied up like that. What kind of man would I be if I didn't at least loosen the ropes?"
Ouka's gaze cut into him, sharp and cold. "A man who thinks with the head on his shoulders, not the one swinging between his legs."
Issei scratched his cheek, sheepish but unrepentant. "Can't help it sometimes."
Kagefusa's tone snapped like a blade against stone. "Enough, Ouka. Do not pretend you did not see. You could have stopped her. You let her go when you had the chance to bind her back."
Her arms crossed, chin tilting higher. "If she reaches Chifusa and the Manyū scroll, so be it. My women shadow her steps. Through her, they will find what must be found."
Ouka's eyes narrowed, but she did not answer.
Women moved like ghosts behind fraying curtains. Some clutched their robes closed across heavy chests, fabric straining to contain what remained of their pride. Others had no need to hide. Their breasts were gone, flattened to smooth skin by the Chichi Nagare technique. Just the hollow certainty that their worth had been drained away. Every bowed head and tightened jaw told the same story. Where milk had once flowed, only shame remained.
Issei's eyes jumped from one woman to the next. His fists curled at his sides. He wanted to roar, to throw someone to the ground and scream, but there was no one here to punish.
"Those bastards monopolizing the world's oppai," he muttered, his voice low and bitter.
Kagefusa walked beside him, quiet. Her hand kept brushing the hilt of her blade. Her jaw was set, her eyes fixed forward, but her posture betrayed her tension. There was guilt in the way she moved.
Ouka led. She said nothing to Issei. She never did when silence made the point louder. Her arms stayed folded. Her hair never stirred. She walked as if even the breeze respected her discipline. Her gaze moved where her head did not. Every closed window, every curtain twitched by a nervous hand. She saw all of them. She moved like someone who had grown used to bearing unspoken truths.
She stopped when a single wail split the stillness. It wasn't the cry of a startled child. It wasn't pain from a scraped knee. It was hunger. The kind of cry that made every woman in the street flinch.
They turned a corner.
A young mother knelt in the dirt outside her door, her robe clinging half-open around her waist. She was trying to nurse her baby, bare chest exposed, trembling. But there was nothing left to give. Her breasts had been taken. Her nipples remained, untouched but useless, small and pale against the unnatural smoothness of her chest. The baby pawed at them and sucked in vain, mouth moving in helpless rhythm, growing more frantic with each failed attempt.
The child screamed louder. The mother flinched at every cry.
She whispered apologies that the child could not understand.
Issei's whole body went rigid with anger. He stepped forward before thinking.
"That's enough. We can help her."
The woman recoiled, clutching her baby tight. Her arms tensed like she meant to flee. Panic widened her eyes. She had seen robes like these before, and the last time, they had come to rob her happiness and pride.
Kagefusa stepped in, catching Issei's elbow. Her grip was firm. Her voice cut low. "Careful. A sword gave her this fate. And your expression isn't helping."
Issei swallowed hard. His voice dropped, but the fire stayed. "We brought yours and Kaede's back. Why should this be any different?"
Kagefusa turned to him, eyes sharp. "That was different. You didn't even know what you were doing until Kaede's restoration proved it could work."
He shrugged. "Still worked. Let's try again."
Behind them, Ouka turned. Her voice came flat and cold. "Do not let your cock think for you."
Issei grinned, unrepentant. "I'm not. Well... not completely."
The mother stared at them, tears at the corners of her eyes. She looked from Ouka to Kagefusa, then to Issei, confused and cornered, afraid and unsure. But she didn't dare to run.
Issei knelt down slightly. His posture relaxed. His voice softened to something that could have passed for prayer.
"Please. I swear, if you trust me, I'll try to return what's been stolen."
The woman's lips parted. Her fingers gripped the baby harder.
"Are you here to take my child?"
Her voice was raw.
"No one's taking anything," Kagefusa said firmly, stepping closer. Her hand no longer hovered near her sword. "He can restore your breasts. That's all. You will be able to nurse your child when it's over."
The mother looked down. Then at her child. Then at her chest. She blinked once, twice.
Finally, she nodded.
"I'm Oume," she said quietly, adjusting the baby against her shoulder. "If you truly mean to help… come."
She rose and led them wordlessly to the back of her hut. They entered through a thin side door into a cramped storeroom. The walls were half-rotted wood, patched with straw. Dust hung in the air, shifting in narrow beams of sunlight that slipped through the cracks.
Grain jars lined the perimeter. A futon lay folded in the center, its surface marked with old oil stains and long use. A single cloth had been hung to create privacy from the small rear opening. It barely reached the floor.
The mother stepped aside and wrapped the child gently in her robe. The infant had grown quiet, exhausted from crying. He sucked on his fingers now, eyes half-lidded.
Ouka moved to the doorway and stood guard. She didn't speak. She didn't breathe loudly. Her fingers rested close to the handle of her katana, but her face was unreadable.
Kagefusa stepped toward Issei and looked at him without smiling. "Let's see if your perversion can be put to use again. Do not disappoint me."
Issei swallowed, his throat dry. His hands twitched at his sides, torn between nerves and excitement. But he knew he would give everything if it meant restoring her breasts so she could feed her child.
Kagefusa removed her outer robe in one fluid motion. Her majestic breasts dropped heavy and rosy, glistening faintly with sweat in the low light. They jiggled slightly as she moved, the weight unmistakably real, the kind that filled a man's heart with happiness just from looking at them. Her nipples stood hard, dark peaks stiff from the night air, each surrounded by a dusky areola drawn tight with cold.
Oume turned slightly, wrapping her arm more tightly around the child. She shifted him higher, shielding his face with the fold of her robe. Her own eyes, however, stayed locked on Kagefusa.
The breasts before her were a sight that struck somewhere deep inside. She remembered the feeling of weight, the gentle ache of milk building beneath her skin, the way her child had once quieted the moment she held him close. All of that was gone now.
A woman had taken a liking to her husband, and Oume had been in the way. She didn't need to kill her. She didn't even need to touch her. All it took was one order sent to the Manyū. One whispered payment. They came like rain, and left her chest hollow and her life broken. Her pride, her place in society, her duty as a mother, all stripped away while her husband looked on and said nothing.
She had woken flat, sore, and alone. Her baby had screamed with hunger. Her husband was already gone.
Her fingers ghosted across the smooth skin of her own chest, and for a moment she forgot to breathe. There was no hatred in her then. Only longing. Only the smallest flicker of something she hadn't allowed herself.
Hope.
Issei's jaw slackened.
Ouka, without looking, flicked him on the back of the head with two fingers. "Focus."
"I am focusing," he muttered, eyes still glued to the bounce and sway. "They're just… perfect."
"Then focus harder. On your power, not your wet dream made flesh."
Kagefusa leaned on without hesitation, her lips capturing Issei's in a kiss that left him breathless. Her mouth pressed firmly, then moved with deliberate hunger, drawing him deeper until he could do nothing but meet her rhythm. Her breasts, heavy and warm, flattened against his chest, the weight of them making his pulse hammer harder with every shift of her body.
Her hand slid down, tugging the fabric from his groin until his cock sprang free. His shaft rose quickly, thickening in the cool air. A neat patch of coarse hair at his base brushed her palm, damp with sweat. He twitched from the sudden chill, but the heat of blood rushing through the meat rod replaced it just as fast.
She broke the kiss just long enough to take his wrist and guide his hand upward. His palm sank into her soft, yielding breast. She pressed it harder against her chest with his hand, forcing him to feel every ounce of weight, softness of her flesh beneath his fingers.
Issei groaned low in his throat, cock stiffening rapidly against her thigh. She smirked faintly, breath hot against his cheek as she kissed him again, deeper this time, tongue sliding past his lips to arouse him fully.
By the time she pulled back, his cock was iron-hard, straining between them. She gave a single look downward, then pressed her breasts together and enclosed him between their heavy curves.
Warmth and softness swallowed his cock and senses whole as she began to move.
"Don't move," she said flatly.
She spat directly onto his tip, thick saliva dripping down the crown and mixing with his precum, then pushed the slick glob downward with her palm, dragging it between her plump tits. The warmth of her skin enclosed him, soft and tight, surrounding him completely. Her grip locked in place, then began to move.
Slow at first. Each stroke was a slide of heaven down the length of his cock.
Issei groaned aloud. His hands clawed uselessly at the mat beneath him.
She picked up the pace. Her breasts pumped along his shaft with increasing speed, weight rippling with each press and lift. Every motion forced his swollen head to poke out from the top of her cleavage, wet and angry-red, before vanishing again between her swells. Precum smeared across her chest, glistening trails that made her skin shine.
"Fuck, Kagefusa," he whispered. "You're gonna make me—"
"Don't forget to use that power on her tits too." Her voice was cool but short of breath.
Ouka's eyes didn't move from the doorway, but her mouth did. "For someone who acts like she's new to this, you handle his cock like it's your daily sparring partner."
Kagefusa's eyebrow twitched, but she didn't stop. Her hands pressed tighter, pushing her breasts together to milk Issei harder.
"Maybe I learn quickly," she shot back. "Unlike some."
Issei's eyes glazed over. His shaft pulsed thickly between her breasts. Precum spilled freely now, mixing with spit and sweat, smearing across her cleavage. She shifted slightly and let one nipple graze his tip on each pass. It twitched every time.
Then she leaned down. Her tongue flicked across his crown, licking up the salty tang of precum. She circled it slowly, savoring the taste, then opened her mouth and took him inside.
The wet heat of her lips wrapped the head, tongue swirling underneath. She bobbed forward until his cock filled her mouth, the base still trapped between her tits. Her throat worked as she swallowed, nose brushing the wiry hair at his base. She gagged lightly, adjusted, then pressed down harder, forcing her throat to stretch.
Issei cried out. His cock throbbed against her tongue. The taste was sharp, thick, a mix of salt and musk that clung to her mouth. Drool spilled down her chin, slicking her tits as she stroked the rest of his shaft with her cleavage.
"God, your mouth…" he gasped, hips twitching despite her order not to move.
She hummed in response, the vibration making his length jerk inside her throat.
She milked him ruthlessly, mouth and breasts working in rhythm. His cock swelled to bursting. He couldn't stop it.
"Boost," he choked out, the word spilling with his climax.
His cock throbbed violently in her mouth. Cum erupted in small bursts, pumping down her throat. She swallowed reflexively, throat convulsing around him, but his load was too much. Thick ropes overflowed, spilling from the corners of her lips and streaking down her chin to splash across her tits. She held him until the last spurt pulsed out, her mouth sealed, swallowing every hot surge that filled her throat.
When she finally let him go, she pulled back with a wet pop. A string of cum clung from her lips to his tip before snapping and sliding onto her chest. She licked the spill from her lips, smearing the rest across her restored breasts with deliberate cruelty.
At the same time, his palm lit against the Oume's flat chest. Golden heat surged from his fingers into her chest. Flesh swelled outward under his touch. Nipples hardened. Beautiful breasts blossomed naturally, heavy and warm.
Her baby sniffed, shifted, and latched instantly.
The mother sobbed, not from pain, but euphoria. As her motherhood itself had returned to her.
Issei lay back, gasping.
Kagefusa, straddling his torso, finally slowed her movements. She let herself stop, his cock softening between her dripping tits, still streaked with seed. Cum clung to her breasts, her chin, the curve of her jaw. Her arms shook faintly from exertion. She swallowed once more, then leaned forward, face glistening, breath ragged.
Ouka crossed to the mother and checked her breast clinically. A careful squeeze near the nipple brought a rich flow of milk. She gave a single nod. "The restoration works."
Kagefusa swayed unsteadily.
Ouka pressed a nerve cluster behind her collarbone and caught her as she slumped sideways. She lowered the swordswoman to the mat with surprising care.
"She needs rest. You drained more than just her strength."
The mother held her child close, still nursing. Her body trembled.
"Thank you," she whispered, bowing so low her forehead touched the floor. "You are truly kind. If you need shelter, my home will be open to you."
She slipped out through the side door, robe drawn tight around herself and the baby.
Ouka waited until the door closed behind her. Then she turned to Issei.
Issei lay flat, eyes unfocused, chest heaving. His cock twitched faintly against the warm mess still slicking Kagefusa's skin.
Ouka stood above them both. "You are a pervert," she said flatly.
Issei let out a tired chuckle. "Yeah. But I'm the amazing kind of pervert."
Her gaze narrowed, but she did not argue. She turned slightly, one hand settling near her blade.
"Where are you really from?" Her voice was quiet, clipped, but not yet accusing.
Issei blinked. "You won't believe me."
"Try."
He rubbed the back of his neck. "Another world. A town called Kuoh. I was a Devil there, part of a devil princess's peerage. I carried the Boosted Gear and fought dragons. Then Great Red, the True Red Dragon God Emperor, threw me across the dimensions… and I landed here."
"And this power?"
"It's called Boost. I get stronger by doubling my strength. I can push that energy into other,s too. If I focus during climax… I can increase the size of oppai."
She raised an eyebrow. "So that is what you were doing. That is how Kagefusa and the other one regained their breasts?"
He nodded quickly. "At first, it was an accident when I met Kagefusa. But then I saw the pattern. Touch, focus, orgasm. That is how it works. I swear I'm telling the truth."
{Convenient theory, partner.} Ddraig's voice rumbled in his skull, dry and edged with disbelief. {But knowing you, you are too stupid to come up with a lie this neat. Which means, unfortunately, it is true.}
"A convenient lie," Ouka said aloud. She stepped closer, her stance calm, but her hand hovered near her weapon. "A man who claims to restore honor by groping his way through women. Convenient indeed."
Before he could answer, she moved. Her sword hissed free, angled at his throat.
Issei did not flinch. One hand caught her wrist. The other gently twisted the blade from her grip and set it aside without so much as nicking the wood floor.
Ouka did not resist. She studied him instead. The ease of his strength, the smooth precision of his motion, the lack of malice in his eyes. He could have broken her arm. He had not.
"You are not like any man I have met," she said at last.
"Didn't I tell you I am not from here," he admitted. "But I did not come to hurt anyone. I just wanted to get stronger."
Her gaze dropped to her chest. Flat, taut muscle over ribs, the faintest swells where full flesh had once been. The thin, pale seams on either side betrayed what the clan had taken by force.
"You said it only works with touch and climax?"
Issei nodded.
"Then prove it," she said. "Prove you are not lying. Restore my ."
She did not wait for a reply. Her hands went to the knot of her robe and tugged it loose. The fabric slipped down in one slow spill, falling from her shoulders to gather around her feet.
Her body was revealed in full under the lantern glow. Her frame was tall, her skin a warm ivory that bore the faint marks of training. Her breasts were flat now, only small peaks of dusky nipples left behind, already stiffening from the air.
Her stomach was flat and ridged with subtle muscle. Her hips curved with strength, tapering into long thighs that looked carved from discipline. Between her legs, her mound was trimmed to a neat dark strip that crowned the folds of her pussy, the inner lips glistening faintly with a wetness she could not hide.
Issei stared openly, then blurted, "I like your oppai the way they are. Flat is justice too, you know."
{By the breasts of Tiamat, why would you say that?} Ddraig groaned. {She is about to kill you or fuck you. Maybe both.}
Ouka stepped forward until her bare chest pressed against him. She looked up, unblinking. "I did not ask what you liked. I asked if you could give back what was mine. Before the clan took it. Before I was robbed of what made me a proud woman."
He exhaled slowly. "I will. I swear in the name of oppai."
Ouka kissed him first. Her lips were cold, but they warmed quickly. She pressed with precision and control, testing him. Issei returned it, pulling her closer until her bare skin was flush to his body. His hands traced the lean lines of her back and waist.
She gasped softly when his fingers brushed the edge of her nipple. The small bud stiffened under his touch, almost painfully sensitive.
When his tongue found hers, she shivered.
He eased her back toward the futon, kneeling her down onto it, then stripped his clothes away in one pull. His cock stood long and proud, hot and wet at its crown. A damp tuft of dark hair framed the base, still sticky with the mix of spit and seed left from Kagefusa's earlier service.
Her eyes widened slightly, though her face stayed composed. She reached toward it, wrapped her hand around his shaft, and stroked once from root to tip. Her fingers could not close around him fully, and her thumb lingered at the swollen ridge where precum had gathered. She rubbed the wetness of her own folds, testing if it was ready, then gave a single nod. "Do it."
Issei pressed his tip against her entrance and pushed in slowly. Her pussy stretched tight around him, heat sucking him deeper inch by inch.
The first full thrust drew a sharp cry. Her back arched, nails digging into his arms. "Too much," she gasped, her voice caught between command and plea.
Issei froze, panting, his cock twitching inside her. "Do you want me to pull out?"
Her jaw tightened. "No… just let me adjust."
Issei grinned down at her, sweat dripping from his brow. "Sorry, I can't hold back when you're this tight."
Before she could protest, his hips slammed forward, burying his cock to the hilt. Her pussy clamped down hard, a wet cry breaking past her lips.
"Ahhh—stop…! I said—" Her words cut off as another thrust rocked through her, the futon creaking beneath them. Her nails raked his back, but her body arched upward into him, cunt sucking him in deeper.
He pumped harder, steady at first but quickly building into fierce, relentless strokes. Each thrust stretched her, soaked her, made her breathless moans spill louder no matter how tightly she bit her lip.
"God, you feel amazing," he groaned, eyes locked on her face. "You're saying stop, but inside you're clamping down on me like you don't ever want me to leave."
Her composure cracked, her head falling back, voice torn from her in sharp, broken cries. "Aahhh… ahhhhn… too much—!"
"Not stopping," Issei growled, hammering into her, his cock thick and hot as it drove her walls wide open. He caught her nipples between his fingers, pinching and rolling them until her whole body jolted beneath him.
Her moan turned to a scream, high and raw, as her orgasm ripped through her. Her pussy convulsed around his cock, gushing wetness down his thighs, but Issei kept pounding, lost in the sound of her voice and the way her once emotionless face twisted with pleasure.
Her pussy clenched in hard waves, milking his cock even as he kept pounding, refusing to let her ride it out in peace.
Issei grinned against her breast, sucking harder, flicking her nipple with his tongue while his hips kept pounding. "That's it. Cum for me. I love hearing that voice when you moan."
"Ahhh… ahhhhn… be silent…" she moaned, nails carving into his back.
He pulled back just enough to look down at her, sweat dripping from his chin onto her chest. "No way. Not when your face looks this good. Usually you're like ice, but now… you're beautiful when you moan."
Her eyes fluttered shut, another orgasm shaking through her, wetter this time, soaking his cock as her body writhed beneath him.
"Boost!" he growled, slamming deep, cock pulsing inside her. His palm pressed to her chest as golden light surged into her skin.
Her back arched violently. A cry tore from her lips as her breasts bloomed back into being, swelling full and heavy, nipples dark and hard.
Ouka's eyes flew open. She gasped, hands trembling as she cupped the restored weight. "I… feel whole again."
Issei pulled out with a ragged groan, stroking his cock fast. "Take it. Feel my hot cum on those breasts I brought back for you!"
He came in thick ropes across her chest, hot seed painting her new curves and dripping down over her nipples. Ouka shuddered at the heat, a low moan escaping before she could catch it.
Her hands rose, cupping the cum-smeared flesh, squeezing experimentally. White streaks spread across her fingers, her nipples slick with it. Her lips parted, trembling between denial and want.
"I should not… want this," she whispered. But her back arched up again, breasts pushed forward, offering themselves to him as cum dripped down her skin.
Issei leaned closer, voice rough. "Then why are you moaning like that?"
Her answer came as another broken cry when his thumb brushed a cum-smeared nipple, her body betraying her once again.
{You continue to disgrace me, partner,} Ddraig said in a voice that was half-scolding, half-resigned. {But gods help me, I have never seen such effective perversion.}
Ouka did not hear him. She was staring at her reflection in the polished base of a rice jar. Her breasts swayed as she cupped them again and again, awe softening her sharp face. Cum clung to her chest and dripped slowly down her stomach.
On the floor, Kagefusa stirred. She blinked, sat up, and the memory came rushing back. Her eyes narrowed at once. "You knocked me out," she said hoarsely. "A coward's move."
Ouka lowered her hands, her smile as cold as steel. "Years I spent flat. Years stolen from me, and not once did I weep. You, though, were undone in a single day."
Kagefusa surged upright, fists trembling. "I was not weeping," she snapped. Her voice cut the air, raw with the pride of denial. The silence that followed felt sharper than blades.
Issei rose, pulling on his clothes with a tired groan, but his voice was firm. "Enough. No more cheap shots at this party. Whatever you two want to say, say it when we can catch that Oppai thief. Until then, the mission is to save all oppai we can. Nothing else."
Ouka's eyes stayed on Kagefusa, hard and unflinching. "Then, when we reach Chifusa, I will take her face first. That is my condition."
Kagefusa's teeth ground together, but she nodded through clenched jaw. "Fine."
The pact held, fragile but unbroken.
Outside, word spread. A few women who had seen that a flat-chested mother went inside the house came with lactating breasts, touched their own flat chests, hope flickering where none had lived in years.
And then, as if carried by the divine wind between them, a single thought passed through their minds.
'If one woman regained hers... can we all?'
Kagefusa shook her head. "No. We cannot linger here a minute longer."
Ouka unrolled a strip of parchment, mapping a swift route along the north spur. "We move right now."
From the ridge road came the sound of hooves. A Manyū patrol rode past, their leader barking orders, a tax ledger open across his lap. Fresh commands to tighten collections, to bleed the villages deeper.
Elsewhere, Kaede's feet carried her fast across the lowlands. She reached her old friend before the night was out, breathless, bringing her warning.
By twilight, the village lay behind them. Three sets of footprints stretched across the fading light. Ouka led, her steps unyielding. Kagefusa followed, silent but simmering. Between two warriors whose breasts bore stories of pride, jealousy, betrayal, and stolen womanhood, Issei walked, the only man in a land where oppai were power, and trust was thinner than silk.
...
The roster of oppai for the full journey is planned, but there's still another spot left for an omake (filler) chapter. Okami has been included in Chapter 5, and the next chapter's focus will be on inn, boobjobs, and the hot springs.
