Chapter 3: Kinky
The rain stopped before dawn, leaving the world washed clean and too quiet. Baki woke alone in the massive bed, the space beside him cold. The scent of sex and his father lingered on the sheets, a tangible ghost. His body felt profoundly used, a pleasantly sore testament to what had happened, but the emptiness where Yujiro had been felt like a fresh wound.
He found him, predictably, on the rooftop. The blood-red moon of the previous nights was gone, replaced by a flat, grey dawn. Yujiro stood at the railing, his back a landscape of muscle and old scars. He didn’t turn as Baki approached, barefoot on the damp tiles.
“You left,” Baki said. It wasn’t an accusation, just a fact that ached.
“You were sleeping,” Yujiro replied, his voice devoid of its usual mocking edge. He finally glanced over his shoulder. “You look… settled.”
Baki didn’t know what that meant. He felt unraveled. “I meant what I said.”
“I know.” Yujiro turned fully now. His eyes were unreadable in the pale light. “Love is a vulnerability. A catastrophic one. I’ve spent a lifetime exterminating weaknesses.”
“Is that what I am?” Baki asked, the words tight in his throat.
Yujiro considered him. A slow, unfamiliar smile touched his lips—not a smirk, but something more contemplative. “You’re a complication. The most interesting one I’ve ever encountered.” He stepped closer, the morning air chilling the space between them. “You say you love me. That means you accept all of me. Not just the fighter. Not just the teacher. Everything.”
A flicker of trepidation sparked in Baki’s gut, but it was instantly drowned by a surge of defiant need. “Yes.”
“Good.” Yujiro’s hand came up, his fingers tracing the line of Baki’s jaw. “Then we continue. But the curriculum changes. We move beyond basic mechanics. We explore the landscape of your submission. Your willingness.”
Baki’s breath hitched. “How?”
Yujiro’s thumb brushed over Baki’s lower lip. “By giving me control. Not just of your body, but of your comfort. Your dignity. You will learn to find ecstasy in the surrender itself.” He paused, his gaze intense. “Do you trust me?”
It was the most dangerous question Baki had ever been asked. Trusting the Ogre was insanity. But loving him was already insanity. This was just the next step into the abyss. “I do.”
“Then tonight,” Yujiro said, his voice dropping to a low rumble that vibrated in Baki’s bones, “you come to me. And you bring nothing but your skin.”
The day stretched, tortuous and endless. Baki tried to train, but his focus was shattered. Every itch, every breeze against his skin, felt like a preview. ‘Bring nothing but your skin.’ The instruction was a loop in his mind. As dusk fell, he stood under a scalding shower, scrubbing himself clean until his skin was pink. He looked at his reflection—the lean, battle-hardened body of a warrior preparing not for combat, but for a different kind of conquest.
He walked naked through the silent halls. The cool air raised goosebumps on his flesh, a constant, humbling reminder of his exposure. The door to Yujiro’s chamber was ajar. He pushed it open.
The room was lit by a single, low lamp. Yujiro was waiting, seated in a heavy armchair. He was also naked, a king on a dark throne. His eyes, gleaming in the dim light, swept over Baki from head to toe, a slow, possessive appraisal that made Baki feel both worshipped and utterly objectified.
“Close the door,” Yujiro said.
Baki did, the soft click sounding final.
“Come here.”
Baki walked forward, stopping a few feet away. The distance felt cavernous.
“Kneel.”
The command was soft, but absolute. Baki lowered himself to the polished floor, the wood cool and unforgiving against his knees. He kept his head up, his eyes locked on his father’s.
Yujiro studied him, a sculptor assessing raw material. “You understand the rules. You speak only to answer a direct question. You move only when I command it. Your pleasure, your release, are mine to give or withhold. This is not a punishment. It is a gift. The ultimate gift one can give another. Do you understand?”
“Yes,” Baki breathed.
“Yes, what?”
Baki faltered for a second. “Yes… Sir.”
A ghost of approval flashed in Yujiro’s eyes. “Good.” He reached to the small table beside the chair. Baki heard the clink of metal, the whisper of leather. His heart hammered against his ribs.
Yujiro held up a pair of sleek, padded leather cuffs. “Your wrists.”
Baki lifted his hands, offering them. His pulse jumped wildly as Yujiro buckled the cuffs securely, the leather warm from his touch. He didn’t stop there. From behind the chair, he produced a longer strap of leather, which he clipped to the cuffs. With a gentle but undeniable pull, he guided Baki’s hands behind his back, securing them there. The position thrust Baki’s chest forward, arching his back subtly. He was bound, helpless.
Yujiro’s hands returned, now holding a simple black silk blindfold. “This is the most important part,” he murmured, leaning close. His breath was warm on Baki’s face. “You are already vulnerable. Now, you will be blind. The world will shrink to my voice, my touch, my smell. There is only me. Do you want that?”
Terror and desire twisted into a single, white-hot wire in Baki’s soul. “Yes, Sir.”
The silk descended, soft and final, plunging him into profound darkness. His other senses screamed to life. The scent of Yujiro’s skin—sandalwood and brute strength. The sound of his own ragged breathing. The feel of the air currents shifting as Yujiro moved around him.
A hand, large and impossibly warm, cupped the back of his neck. It was a gesture of absolute ownership. “Beautiful,” Yujiro whispered, and the word in the dark felt more intimate than any kiss.
Then, the touch began to wander. Calloused fingers traced the shell of Baki’s ear, down the column of his throat, over the flutter of his pulse. They mapped his shoulders, his collarbones, his pecs, thumbs brushing lightly over his nipples until they peaked into tight, sensitive buds. Every touch was deliberate, agonizingly slow. Baki trembled, his bound hands flexing behind him. He was hard, his cock straining up against his abdomen, already leaking a bead of precum onto his skin.
“Such a responsive body,” Yujiro mused, his voice a low vibration in the dark. His hand slid down Baki’s stomach, fingertips skimming the trail of hair below his navel. He bypassed Baki’s aching erection completely, instead gripping his hip, holding him steady. “Stay.”
Baki heard the click of a cap, the wet sound of lubrication. His breath hitched. He felt the broad, slick head of Yujiro’s cock nudge against his lips.
“Open.”
It was a command that shattered any last pretense. This wasn’t the desperate, hungry blowjob from before. This was ritual. Baki parted his lips, and Yujiro fed his length into his mouth, not thrusting, just allowing the heavy, velvety weight to settle on Baki’s tongue. The taste was musky, uniquely Yujiro. Baki relaxed his jaw, letting his father use his mouth, learning the rhythm Yujiro set—slow, deep penetrations that made Baki’s eyes water behind the blindfold. He couldn’t move, couldn’t touch, could only accept and serve. A strangled moan worked its way up his throat, vibrating around the invading flesh.
Yujiro pulled out with a soft pop. A thumb swiped over Baki’s wet, bruised lips. “Good. So good for me.”
The praise burned through Baki like sunshine. Then he was being maneuvered. Strong hands guided him up onto the bed, onto his hands and knees. The leather strap connecting his cuffs was adjusted, pulling his arms further up his back, deepening the arch. He was presented, exposed, blind and bound.
Yujiro’s hands spread him open. Cool lubricant dribbled down his cleft. A finger, thick and slick, pressed inside, working him with that same infuriating patience. Then a second. The stretch was exquisite, a familiar burn that promised more. The fingers crooked, finding that perfect spot, and Baki cried out, his head dropping between his shoulders.
“You need it, don’t you?” Yujiro’s voice was close to his ear. “This is what you really want. Not just to be fucked. To be taken. Completely.”
“Yes, Sir! God, please…”
The fingers withdrew. The blunt, immense pressure of Yujiro’s cockhead replaced them. He pushed in, not with the slow, romantic pace of the night before, but with a single, continuous, relentless drive. Baki screamed as he was filled, stretched to the absolute limit, the invasion a breathtaking conquest of his entire being. Yujiro sheathed himself to the hilt and held there, his body draped over Baki’s back, his mouth on the knotted muscle of Baki’s shoulder.
“You’re mine,” Yujiro growled, the words a hot brand against Baki’s skin. “Every last inch. Every sob. Every drop of come. Mine.”
He began to move. This was fucking in its purest, most raw form. Deep, piston-like strokes that knocked the air from Baki’s lungs with each impact. There was no hiding, no gentle building.
He hammered into him. Each thrust was a declaration, a physical manifesto of ownership that slammed Baki’s bound hands higher up his own back. The air left Baki’s lungs in punched-out grunts, each one timed with the wet, savage slap of skin on skin. His world was the smell of sweat and sex, the bite of leather on his wrists, the devastating fullness splitting him open again and again.
“You feel that?” Yujiro snarled, his voice thick and raw. “That’s me. You’re just a sheath. A warm, tight hole for my cock.” His hand fisted in Baki’s hair, yanking his head back, arching his spine to an even more vulnerable angle. “Tell me what you are.”
“Yours!” Baki sobbed, the word torn from him. “I’m just yours!”
“Damn right.” Yujiro’s pace became erratic, a brutal, frenzied rhythm that shattered any last pretense of control. He was using him, purely and utterly, and Baki was melting into the usage, his own neglected cock leaking a steady stream onto the sheets beneath him. The pleasure was a paradox—a sharp, bright pain at the point of invasion that bloomed into a shocking, deep-seated euphoria.
Yujiro’s other hand snaked around Baki’s hip, fingers digging into the muscle of his abdomen before closing around his throbbing length. The touch was rough, demanding. “You come when I tell you,” he growled into Baki’s ear, his thrusts never faltering. “Not a second before. You hold it. You choke on it.”
Baki whimpered, teetering on a knife’s edge. The dual assault was too much. The deep, pounding possession from behind and the ruthless, calloused stroking from the front coiled a spring in his gut so tight he feared it would break him. He was babbling, a stream of “please” and “dad” and “sir” that meant nothing and everything.
Yujiro’s breathing hitched, a ragged edge signaling his own approach. His grip on Baki’s hair tightened painfully. “Now,” he commanded, his voice a guttural crack of sound. “Come for me, you filthy boy. Now!”
The order snapped the tension. Baki’s orgasm erupted like a silent scream, seizing his entire body in a violent, wrenching convulsion. His vision went white behind the blindfold as his cock jerked in Yujiro’s fist, stripes of hot come painting the rumpled sheets beneath him in frantic pulses. The clenching of his inner muscles around the brutal, driving cock inside him pulled a roar from Yujiro.
He buried himself to the root, his body locking against Baki’s as his own release flooded Baki’s depths, a scalding, seemingly endless torrent that filled the incredible emptiness he’d created. He ground his hips in deep, circular motions, milking himself, marking his territory from the inside. The sensation of being claimed so completely, so biologically, unspooled a secondary, weaker ripple of pleasure from Baki, leaving him a shuddering, spent ruin.
For a long moment, the only sounds were their heaving breaths and the soft drip of water from the rooftop spring outside. Yujiro stayed lodged within him, his weight a crushing, welcome anchor. Slowly, his hand released Baki’s hair, coming to rest instead on the sweat-slicked plane of his back. The gesture was almost… calming.
Then, he pulled out. The sudden emptiness was a shock, a visceral loss. Baki heard the soft rustle of movement, then the click of the leather cuffs being unbuckled. The binding fell away, blood rushing back into his fingers with a painful tingle. Before he could move, the blindfold was gently lifted.
The dim lamplight was blinding. Baki blinked, his eyes swimming with tears of exertion and overwhelming sensation. Yujiro was there, his expression unreadable. He didn’t speak. Instead, he cupped Baki’s face, his thumb wiping at the tear-tracks and spit on his cheek. Then he gathered him, pulling him from the precarious kneel into his lap, against the solid wall of his chest. Baki went boneless, his head lolling onto Yujiro’s shoulder, his body trembling with aftershocks.
Yujiro reached for a discarded towel, dampened it with water from a bedside carafe. With a startling, methodical gentleness, he began to clean Baki’s stomach, his thighs, the tender flesh between them. The cool cloth was a shock, then a relief. Baki simply watched, his mind a numb, buzzing blank.
“You did well,” Yujiro said finally, his voice back to its normal, measured timbre. It wasn’t praise for a fighter. It was an assessment of a performance, but it made Baki’s throat tighten.
“I didn’t do anything,” Baki mumbled into his skin. “I just… took it.”
“Exactly.” Yujiro tilted Baki’s chin up, forcing eye contact. His gaze was fierce, analytical. “That’s the lesson. True strength isn’t just in delivering force. It’s in the capacity to withstand it. To absorb and not break. You think letting me use your body like a toy makes you weak?” He shook his head, a faint, cruel smile on his lips. “You’ve never been stronger. You surrendered completely, and you’re still here. Still breathing. Still mine.”
The logic was twisted, a perversion of his fighting philosophy, but it resonated in the deepest, most broken part of Baki’s soul. He had survived the Ogre, in every conceivable way. He nuzzled closer, inhaling the familiar scent now mingled with their shared musk.
“Does it make you weak?” Baki asked, the question slipping out in a drowsy haze. “Wanting me like this?”
Yujiro’s body went very still. The silence stretched, taut and dangerous. Baki felt the rumble in his chest before he heard the words.
“It makes me interested,” Yujiro said, his arms tightening possessively. “And anything that keeps me interested gets to live. Now sleep. You’ll train tomorrow. Harder than ever.”
It wasn’t an answer. It was the only answer Baki would ever get. As he drifted into an exhausted, sore oblivion, cradled in the arms of the strongest creature on Earth, he understood the new battlefield. The fight was no longer to defeat him. It was to remain, forever, the only thing he couldn’t bring himself to destroy.
The heat of the shower did little to loosen the clenched apprehension in Baki’s gut. He scrubbed at the phantom feeling of the leather cuffs, the tender ache in his muscles a cherished brand. The training that day had been a silent, brutal affair. Yujiro offered no praise, no critique, just force meeting force until the sun bled out behind the Tokyo skyline. Each blow Baki took felt different now, layered with the memory of a different kind of submission.
He found Yujiro not on the rooftop, but in the sterile dojo, wiping down a weight bar with a rough white towel. The overhead lights cut harsh angles across his torso. "You're stiff," Yujiro said without looking up. "Holding onto yesterday. That's weakness."
"I'm not holding onto it," Baki countered, his voice too sharp. "It's just… there."
Yujiro finally glanced at him, a flicker of something predatory in his gaze. "Then we replace it with something newer. Something deeper." He dropped the towel. "On the mat. Now."
This wasn't the shadowed bedroom. This was their temple of violence, the resin mat cold and unforgiving under Baki's knees. Yujiro approached, not with the slow seduction of the night before, but with the focused intent of a combatant. He fisted a hand in Baki’s hair, not to hurt, but to control, tilting his head back. "You want to be mine? Prove it here, where it matters. Where I know best."
He kissed him, and it was all teeth and possession, a battle for air that Baki surrendered willingly. Yujiro’s other hand ripped at Baki’s shorts, the fabric tearing like tissue paper under his strength. The cool air of the dojo hit Baki’s bare skin, a shocking contrast to the heat flooding his face. Yujiro broke the kiss, shoving him backwards until Baki sprawled on the mat, his head swimming.
"There are no rules here," Yujiro said, his voice low and thick as he stripped his own pants away. His erection was already full, a heavy curve of intimidating flesh. "No blindfold. No gentle words. You see everything. You take everything."
He didn't prepare him. There was no ritual, no cool slickness of lube. Just Yujiro’s spit-wet hand working over his own cock, then the brutal, dry pressure against Baki’s entrance. Baki’s eyes flew wide, a gasp stuck in his throat. He knew what was coming, knew the pain was a feature, not a bug. "Please," he choked out, not for mercy, but for it.
Yujiro pushed.
The burn was catastrophic, a white-hot lance of pure sensation that blurred Baki’s vision. He screamed, the sound echoing off the dojo walls, his body arching in instinctive protest. Yujiro didn't stop. He leaned over him, his weight pinning Baki’s hips to the mat, and sank in another inexorable inch. The stretch was obscene, a tearing, claiming burn that felt like being remade from the inside out. "Fuck! Dad, fuck, it's—"
"Too much?" Yujiro growled, his own breath hitching, his face a mask of concentrated fury and desire. He was sweating. "You said you could take all of me. Was that a lie?" He pushed again, burying himself another fraction deeper. The pain splintered, giving way to a shocking, full-bodied possession that stole the air from Baki’s lungs.
"It's not—" Baki sobbed, his hands scrabbling at Yujiro’s back, finding no purchase, nails digging into scarred skin. "Don't stop. Don't you fucking stop."
With a final, grinding thrust, Yujiro seated himself completely. They were joined, raw and painful and profoundly intimate. For a second, they were both still, linked by shared, ragged breaths. Yujiro looked down at him, his expression unreadable, eyes searching Baki’s face for the breaking point. He saw tears, saw the tremors of agony, but he also saw the unwavering, defiant hunger staring back.
He began to move. It was a brutal, shallow fucking, the dry, searing friction a punishment and a sacrament. Each withdrawal was a gasp of relief, each drive forward a fresh, exquisite violation. Baki's cock, trapped between their bodies, leaked profusely onto his own stomach, the pleasure somehow sharper, more desperate, woven inseparably with the pain. "You feel that burn?" Yujiro grunted, his hips snapping forward. "That's me marking you. My cock is the only thing that's ever really fit inside you, isn't it?"
"Yes! God, yes!" Baki cried, his legs wrapping around Yujiro’s waist, heels digging into the small of his back, pulling him deeper into the fire.
Yujiro’s control was fraying. His movements became less measured, more ragged, a desperate chase for his own climax. He shifted Baki’s hips, angling himself, and on the next thrust, he hit it—the secret, devastating spot that made Baki see stars. A punched-out wail tore from Baki’s throat, his entire body convulsing. The pain dissolved, transmuted into pure, undiluted electric pleasure.
"That's it," Yujiro snarled, his voice breaking. He hammered into that spot, again and again, a relentless, perfect assault. "You come on my cock. You come from being split open by me. Do it."
The command was superfluous. Baki’s orgasm detonated, a raw, silent scream that locked his muscles and pulled his consciousness into a narrow, blinding tunnel. He came in violent, helpless spurts that slicked both their stomachs, his channel clamping down in rhythmic, milking spasms around the brutalizing thickness inside him.
The sensation tore Yujiro over the edge. With a sound that was pure animal triumph, he drove in one last, deep time, his body going rigid as he emptied himself. His release was scalding, a flooding, possessive claim that filled the raw, aching space he’d carved. He shuddered through it, his forehead dropping to Baki’s shoulder, teeth grazing the skin.
They lay like that, joined in the aftermath, the only sound their labored breathing and the hum of the dojo lights. Yujiro was the first to move, pulling out slowly. Baki winced at the fresh, wet ache, a stark reminder. But then Yujiro did something he never had. He didn't get up. He rolled onto his back beside Baki on the cold mat, staring up at the ceiling, one arm thrown over his eyes.
"Fuck," he breathed, the word ragged, almost astonished.
Baki turned his head, watching the steady rise and fall of his father’s chest. He saw not the Ogre, but a man spent, momentarily hollowed out. The sight was more intimate than any penetration. Carefully, his body screaming in protest, he shifted onto his side, curling against Yujiro’s massive frame, his head finding a space on the granite shoulder.
Yujiro’s arm didn’t embrace him, but it didn’t push him away. It remained where it was, a warm, heavy weight. After a long silence, his voice, quieter than Baki had ever heard it, cut through the stillness. "You're the only thing that doesn't feel like nothing afterward."
The admission hung in the air, fragile and monstrous. Baki understood. For Yujiro Hanma, the strongest, everything was transient, easily broken, leaving only void. But this, this twisted, raw thing between them, left a feeling. It left a mark. It left Baki.
He pressed closer, his lips brushing the skin below Yujiro’s collarbone. "Then I'll always be here afterward," he whispered. It wasn't a promise of forever. It was a statement of fact, as solid as the mat beneath them. He felt Yujiro’s chest expand with a deep, settling breath. The arm over his eyes shifted, and his hand came down, not in a caress, but to rest, heavy and final, on the back of Baki’s head, fingers tangling in his sweat-damp hair. It was an anchor. It was a seal.
Outside, the city’s endless night thrummed, a distant heartbeat. In the bright, silent dojo, they existed in the new level they had forged—a level built on shared wreckage and the staggering, unspoken truth that in this world of brutal absolutes, they had somehow become each other’s only relative.
