#rinzu

Ran had always been the easiest way to provoke him, especially when the older Haitani leaned into it with that effortless teasing charm, brushing close and murmuring things in his ear while pretending it was all harmless. Rindou never bought the act. Not once.

Rindou’s hand suddenly tangled in Sanzu’s hair and yanked his head back, forcing his spine into a deep arch that left him gasping as his other arm slid around his throat, holding him firmly in place while he continued to drive into him with a rhythm that left him shaking.

“And…” he grunted. His mouth hovered close to Sanzu’s ear, his breath warm against his skin while the rough edge in his voice carried a warning that made his pulse race. “What happens when you don’t listen to me?”

Sanzu could barely think. Every movement of Rindou’s hips struck a spot that made stars burst behind his eyes, and the pressure building deep inside him climbed higher with every second until the question he asked barely registered through the haze.

He did not let Sanzu ignore it. His free hand cracked lightly against his cheek, the sting snapping his attention back as his voice hardened. “Answer,” he barked. “I didn’t fuck you that stupid yet.”

Sanzu’s body clenched around him. If his arm had not been locked around his neck he would have collapsed forward onto the counter completely, his breath coming in uneven gasps as pleasure and tension tangled inside him.

“I get…” he faltered. Another thrust forced a helpless sound from his throat as his words dissolved into a gasp before he forced them out. “Ah… I get punished.” Another slap followed.

The sharp contact sent a jolt through him that pushed him even closer to the edge, his body tightening as the familiar wave of release rushed toward him faster than he could stop it. Rindou noticed immediately. By now he knew Sanzu’s reactions too well to miss the way his muscles tensed around him or the subtle change in the sounds he made when he was about to fall apart. He was an open book to him. And he had no intention of letting him finish.

His arm loosened around Sanzu’s neck without warning, and a second later the heat filling him vanished completely as he pulled out of him all at once, leaving his body clenching helplessly around nothing.

Rindou grabbed his hair again. It wasn't hard enough to truly hurt him, but the sharp pull still stung as he guided Sanzu across the room and bent him over the armrest of the sofa before letting go, leaving him draped awkwardly across the furniture with him completely at his mercy.

“Stay,” he ordered.

Rindou turned away without another word and crossed the room to grab something from a nearby table, and even though Sanzu could not see it yet he already had a strong suspicion of what he was reaching for. His heartbeat sped up immediately. Fear and anticipation tangled together inside his chest.

By the time he returned, Sanzu’s pulse was loud in his ears and his thoughts had turned hazy with the strange mixture of nerves and excitement that always came when he looked at him like this.

Rindou suddenly dropped to his knees in front of him. His hand closed in Sanzu’s hair again and he tugged his head upward, forcing him to look directly at him as his glossy eyes searched his face and took in every small detail. His hair was slightly disheveled from earlier, and the hard set of his expression made his features look almost unfairly beautiful. God, he looked good like this.

He noticed that Rindou was still fully dressed from whatever job they had returned from earlier, his tie loosened just enough to suggest impatience while his gloves remained firmly in place and a faint speck of blood decorated the sleeve of his jacket. The sight made heat coil low in his stomach. This situation was completely messed up, and yet the rush of it all only pulled him deeper into the moment. Sanzu felt the familiar warmth of arousal spreading through his lower body. “Please,” he started softly.

His voice wavered as memories of the last time he had pushed him too far flashed through his mind, recalling the dull ache that had lingered for days afterward and the way sitting down had become a careful, miserable process. “Please be gentle.” He knew it was a long shot.

The last time he had crossed the line like that, his normally attentive partner had taken a clear and almost devious satisfaction in watching him deal with the consequences of his own stubbornness, especially every time he winced while trying to sit down afterward. He had looked delighted. The growing bulge in his pants had refused to hide how much he enjoyed the situation.

“You know I can’t do that,” Rindou replied calmly. His tone was steady and almost patient, though there was a rough edge underneath it that told him he meant every word he was about to say. “I would be letting you down if I did.”

Fuck.

He released Sanzu’s hair then and let his head fall back against the couch cushion, his cheek pressing into the expensive fabric while his hair spilled loosely around his face. Rindou stood again. He moved with slow, deliberate steps until he was positioned behind him once more, the quiet sound of his shoes against the floor stretching the tension until it felt unbearable.

He instinctively tried to shift away. Though he knew the attempt was useless, since the angle he was bent over the armrest and the tight restraints holding his wrists made even the smallest movement difficult. A shiver ran through him.

Rindou’s gloved hand found his ass and began kneading slowly, testing the firmness of the flesh before giving it a light experimental slap that made him inhale sharply.

“This will hurt,” he said plainly. Despite the bluntness of the warning, Sanzu could hear the slight hitch in his voice that betrayed how much the moment affected him too.

“Fifteen,” Rindou continued. His tone sharpened with quiet authority as he added the rule that always made his stomach flutter with nervous excitement. “I want you to count every one of them.”

“And if you miss one,” he finished, “we start over.”

Sanzu was already trembling. His cock pressed against the sofa as the anticipation built higher and higher, leaving his breath shallow while his fingers curled uselessly against the restraints holding his wrists together.

“Yes, sir,” he whispered.

Time seemed to stretch into something slow, and he swore he could hear the faint rush of air as the paddle was lifted before it came down sharply against his backside with a sting so sudden and intense that it nearly knocked the breath from his lungs. He had not been bluffing.

“O… one,” he gasped weakly. His voice barely made it past his lips as the lingering sting spread across his skin.

“And?” he prompted. His fingers brushed against his entrance for a brief teasing moment, circling once before pulling away again as if the contact had only been meant to remind him how vulnerable he was right now.

“Thank you, sir,” he added quickly. The correction came out breathless but clear.

Rindou hummed in approval. “Good boy.”

Another strike followed. “Two… t-thank you,” he stammered, his voice shaky as the sting spread across his skin and settled into a warm burn that made his toes curl against the couch. Then came another. And another after that, each strike landing with the same unforgiving force as the last while Rindou showed no sign of easing up, the steady rhythm leaving Sanzu’s body trembling and his thoughts slowly dissolving into something blissfully empty.

The heat in his ass had grown intense by now, every nerve buzzing as the sting mixed with pleasure and the constant awareness that his merciless partner was standing just behind him, towering over him while he delivered every strike with careful precision. Nothing else mattered.

The world had narrowed to the sharp smack of the paddle, the pounding of his pulse in his ears, and the overwhelming heat pooling low in his body as pleasure and pain twisted together in a way that made him dizzy. If heaven existed, he was pretty sure it looked something like this.

“Last one, angel,” Rindou’s strained voice came from behind him.

The nickname was familiar but rarely used, and hearing it now sent a shiver racing down Sanzu’s spine while the tiny hairs along the back of his neck stood up instantly. He almost moaned just from that.

The final strike came down a second later, landing harder than any of the others and jolting his body forward as the sharp sting exploded across his skin. He had absolutely saved the worst for last. Even through the haze clouding his thoughts he swore he could practically hear the faint smirk on his lips, the kind of smug satisfaction he always carried when he knew exactly what he was doing to him.

His hair was still pooled around his face. His chest pressed firmly into the soft fabric of the couch while his watery eyes stared unfocused at nothing in particular, his breathing uneven as the sting pulsed across his skin. Then he felt his hand on his back.

His gloved fingers traced slow circles along his lower spine, soothing and gentle in a way that contrasted sharply with the punishment he had just delivered before he stepped into view and pressed a soft kiss against the top of his hair.

“How are you feeling?” he asked gently.

“Amazing…” Sanzu answered honestly. His eyes drifted up toward him, glassy and unfocused while his flushed face and slack expression made it obvious he was still floating somewhere far away. A tiny strand of saliva slipped from the corner of his mouth and stained the sofa. He looked completely wrecked and absolutely stunning.

“Good,” Rindou said. His tone sharpened again almost instantly as his expression shifted, his gaze turning colder while he looked down at him with that familiar intensity that always made his stomach twist.

“Because we’re not done here.” He was going to drive him insane tonight, he was certain of it.

He felt his hands move to his arms as he lifted Sanzu carefully off the armrest, steadying him when his shaky legs threatened to buckle before guiding him into a different position on the couch. His back pressed against the cushions now and his legs were spread apart on either side of him while he positioned him exactly where he wanted, leaving his body open and vulnerable beneath his gaze.

Rindou slid his arms under his thighs to pull him slightly forward until his hips rested near the edge of the couch, leaving his ass barely supported while the position forced his legs further apart. Then he slapped his cock.

The sudden contact drew a startled moan from Sanzu’s lips as the sharp sensation pulsed through his body, his hips jerking slightly before he lowered himself to his knees in front of him. A second later his tongue dragged slowly along the tip. His back arched immediately against the couch while the rope binding his wrists dug deep into his skin, the unexpected pleasure sending a wave of heat rushing through his entire body.

“Fuck,” he breathed. His voice was rough as he lingered there, his grip tightening on his thighs while he looked up at him through half-lidded eyes. “You taste so fucking good.”

And just like that, he was back on him. His tongue moved with practiced ease along his cock, licking slow stripes up and down before taking the tip into his mouth. His cheeks hollowed as he drew him in with a swift motion while he paid close attention to every reaction he gave until he heard his breath hitch and felt his body tense beneath his hands. He had him figured out.

Rindou devoured him like a starving man, occasionally lifting his gaze to meet his with an intensity that made his pulse race even faster than the sensation of his mouth alone. “God, Rindou,” he moaned. His bound hands tightened around his own arm behind his back as he tried to steady himself against the overwhelming rush building inside him. “Feels s’good.”

He hummed softly against him, the vibration sending a shiver through him while his tongue continued its relentless work. The sound alone made his hips twitch as the pressure inside his cock tightened again, that familiar wave of pleasure building faster and faster until it felt impossible to hold back.

“Yes… n’ah,” he moaned breathlessly. His voice cracked as he tilted his hips upward, chasing the exact spot that had his nerves sparking. “Yes, right there… haah…” He ground himself against his mouth without shame. His hips rocked instinctively as he chased the release that had been dangling just out of reach all night, his body moving on instinct while every nerve in his skin felt painfully alive.

Rindou stopped. For the second time that night he pulled away before he could finish, leaving Sanzu’s body suspended right at the edge while the pleasure that had been about to break suddenly vanished. The frustration hit immediately. A shaky breath escaped him as tears welled in his eyes and began sliding down his flushed cheeks, the overwhelming tension left behind making his entire body tremble. He needed to come so badly. His skin felt like it was burning from the inside out while his cock throbbed helplessly, aching with the absence of the pressure he had been chasing.

If his hands had not been tied, he would have grabbed him. He would have dragged him back down and buried his fingers in his hair just to force him to keep going until he shattered. But the restraints allowed none of it. His wrists were pinned uselessly behind him, leaving him completely at his mercy while the younger Haitani rose to his feet and towered over him.

His expression was calm, yet the look in his eyes made it obvious how much he was enjoying every second of this, especially when paired with the angry red tip of his cock and the way his shaft stood painfully erect.

“You come on my cock,” he said sharply. His voice carried a rough edge as his hand returned to his body, gripping his thigh as he shifted him again with deliberate control. “Or you don’t come at all.”

A second later he moved him onto the floor.

He ended up on his back, staring up at the ceiling above while he tried to steady his breathing and gather the scattered pieces of his thoughts. At least the lighting was dim. The soft glow from the corner of the room was far kinder than the harsh brightness of the ceiling light that would have made the moment feel far too exposed.

He felt him before he saw him. Rindou’s hands settled on his thighs and squeezed firmly before pressing them upward toward his chest, folding him into a position that left him completely open beneath him. The pose was shameless. It left nothing hidden from his gaze and everything fully on display for him to look at, something he clearly took advantage of as he leaned over him, his hair framing his face.

The shadows from the dim lighting framed his features while the hungry curve of his lips made it clear exactly what was running through his mind. His pants had come partially undone by now. Both the fabric and his boxers had slipped down to the middle of his thighs, giving him more freedom to move while revealing just enough of his body to make him stare. And stare he did.

His eyes dragged slowly up and down his body as he took in the sight of him towering above, his tattoos adorning toned muscles, clearly appreciating the view in a way he did not even try to hide. Rindou noticed. The subtle twitch of his cock was impossible to miss.

“Desperate whore,” he muttered. The words sounded far more like praise than an insult.

Finally, Rindou lined himself up with his entrance.

There was no need for any more prep with how worked up he already was, and he pushed inside him in one smooth motion that buried him impossibly deep. A low, guttural moan slipped from Sanzu’s throat. He stayed there for a moment, savoring the tight heat wrapped around his cock before slowly pulling out again and thrusting back in as he began to set a rhythm.

His arms braced on either side of him. Strong and toned, they caged his body between him and the floor while his gaze pinned him in place just as firmly as his weight did, leaving him nowhere to go and no desire to escape. Their bodies were tightly connected. His legs were draped over Rindou’s shoulders, forcing his thighs up against his chest and locking him into a deep mating press that left him reaching inside him again and again with every thrust.

The position strained his arms behind his back. The rope dug painfully into his wrists as the tension pulled at his shoulders, yet the pressure of his body and the way he held him there made him feel completely powerless beneath him.

“Ah…” he breathed. His voice was shaky as his chest rose and fell while he struggled to keep up with the sensations rushing through his body. “Harder, Rin… please. I… I need you.”

His eyes rolled back and his head tipped to the side as his gaze drifted unfocused across the room, unable to settle on anything while the only clear sensation in his mind was the feeling of him buried deep inside him. Rindou did not need to be told twice. He picked up the pace almost immediately, his thrusts turning rough and quick as he drove himself into him over and over again.

He bucked into him like an animal in heat, chasing his own release without even noticing the strain beginning to build in his muscles as the intensity of his movements increased. One of his hands reached for his face. He hooked his thumb into his mouth and pressed down just enough to force his attention back onto him when his dazed eyes tried to drift away again.

“Look at me,” he murmured.

When his gaze finally locked onto his, his fingers slid from his jaw to his throat, wrapping loosely around his neck before tightening slightly in the way he knew he liked. The pressure stole a little of his breath. His lungs struggled to pull in air as the squeeze made his head feel lighter, the lack of oxygen mixing with the pleasure rushing through his body until his thoughts blurred together completely.

“I’m close,” he said.

The words came out strained as he punctuated them with a rough thrust that broke the rhythm for a moment before he pushed deep again. “Want you to come with me.”

His grip around his throat tightened a little more before he leaned down and kissed him. The kiss was deep and hungry as he swallowed the moan trying to escape his throat, his tongue searching for his while the muscles moved against each other in frantic, desperate strokes that said far more than words ever could.

Rindou felt him tighten around him. The sudden, intense squeeze told him that he was close, and he kept his pace steady as he rocked into him with deep, controlled thrusts while chasing the release building in his own body.

He bucked beneath him. His legs lifted higher and closed behind his head, locking him firmly in place as his body instinctively tried to pull him deeper, even though the position already left almost no room for movement. Even with the limited space he did not slow down and instead continued driving into him, his hips rolling forward with determination until two more strokes pushed him over the edge completely. His body clenched around him again.

His legs trembled violently while the sound that escaped his throat was so raw and helpless that it sent a fresh surge of heat through him despite the exhaustion already creeping into his muscles. His release filled him while he held himself there for a moment longer, breathing heavily as the last tremors of pleasure moved through both of them.

Slowly he pulled out. A small trail of his release slipped from his cock as he withdrew, leaving him staring down at the mess they had made while he tried to catch his breath. His expression was dazed and sinful, his flushed face and unfocused eyes making it obvious that he was still floating somewhere deep in the afterglow. He never got tired of that sight.

It was one of his favorite moments, the quiet seconds after everything when the tension had finally broken and he looked completely undone. His hair was messy from where his hands had been earlier, his cheeks still flushed and his lips slightly parted as he tried to catch his breath, and the sight of him like that always stirred something deep and possessive inside his chest. All because of him.

Rindou let himself look for a moment longer before he finally reached out, his fingers brushing gently along his cheek. There was no trace of the roughness from earlier in the way he touched him now.

“C’mere,” he murmured quietly. His voice had lost the sharp edge it carried before as he helped him sit up, supporting him carefully while he reached for the rope still looped around his wrists. When it fell away his eyes turned to the marks it had left behind, angry red lines wrapped around his wrists where the fibers had pressed against his skin. The contrast against his otherwise smooth skin made his chest tighten and his thumb brushed across one of the marks. He watched him.

His eyes were softer now, the earlier haze of pleasure slowly fading while he studied his face with that familiar warmth that always seemed to see right through him.

Before he could even move away to put the rope aside, his arms slid around him and pulled him closer in the way he had clearly wanted to do all night.

“I love you, Rin,” he whispered. His voice was gentle as he leaned in and pressed a slow kiss to his lips, the kind of kiss that carried nothing but affection and reassurance. It caught him off guard. Not because the words were unexpected, but because he always seemed to say them at the exact moment he needed to hear them the most.

Despite the dangerous work they did and Rindou's cold demeanor he showed the rest of the world, he had always been able to see the quiet insecurities he kept buried underneath it all. He rarely pushed those places. But whenever he did, he made sure to follow it with something that reminded him he was still loved beyond all of it.

Rindou’s arms slid around his waist and pulled him firmly against him while he buried his face into the curve of his neck, holding him a little tighter than he normally would as he breathed in slowly. The steady warmth of his body against his chest grounded him far more than he would ever admit out loud.
