The afternoon sun streamed through the glass windows, casting warm, golden pools of light onto the floor of Rin Nohara's living room. Saiki and Rin sat opposite each other on the sofa, a low table between them holding half-cooled tea and the remnants of their snacks.
They spent the hour talking, drifting from amusing stories about their Academy days to the changes they had undergone since graduation. They spoke of classmates lost in the war, the cruelty of time, and the fragility of life.
"I really miss those times..." Rin whispered, a faint shadow of melancholy in her eyes. "Back when everyone was together. The training was grueling, but every day was full of laughter."
Saiki nodded silently. His own memories of the Academy weren't particularly fond—he had arrived with the memories of a past life and a power that far surpassed his peers. School had always felt like a necessary observational phase rather than a social experience. But seeing the sincere nostalgia in Rin's gaze, he didn't have the heart to interrupt.
However, as the conversation deepened, Saiki sensed a shift.
Rin's voice began to tremble. An unnatural flush crept across her cheeks. Her fingers twisted the hem of her shirt unconsciously, her eyes darted away, and her breathing quickened. She stole glances at him before looking down, appearing trapped in a cycle of bashful hesitation.
Saiki assumed the talk of the past had simply stirred her youthful feelings, making her shy. After all, her crush on him was no secret. From the brown-haired girl who used to steal glances at him in class to the medical ninja who had shielded him on the battlefield, her affection had always been pure and warm.
So, when Rin's body began to shiver and her voice dropped to a whisper before she took a deep breath and shouted with every ounce of her courage, Saiki wasn't surprised.
"Saiki-kun, I love you!"
The girl's voice echoed clearly in the quiet house. Her face was entirely red, yet her eyes locked onto his, fueled by a lifetime of suppressed longing.
Saiki looked at her—at the shimmer of tears, the clenched fists, and the shaking shoulders. He offered a gentle smile. "I've always known, Rin."
The response made her eyes shine brighter, but her expression suddenly turned grave, bordering on desperate.
"No, Saiki-kun, you don't understand—I love you so, so much! Since the Academy, until now! Every day, every second, I have loved only you!"
This burning confession hit Saiki with the weight of a stone dropped into a still lake. He prepared to say something to soothe her, but Rin was faster.
Under the influence of the curse mark's hidden power, her long-suppressed emotions erupted like a volcano. The shy, introverted girl manifested a level of aggression and initiative that defied her nature. She bolted from her seat and lunged at him.
Her soft body slammed into his chest, and her warm lips pressed clumsily against his. The kiss was devoid of technique—raw, panicked, and hot with a desperate heat.
Saiki froze. He was no stranger to proactive women—Tsunade's fire, Kushina's passion, Nono'u's tenderness, Mei's submission—but Rin was different. She was too simple, too clean, like a blank sheet of paper. To see her act so boldly left him momentarily stunned.
But the body in his arms was shaking. The lips kissing him were trembling. He could feel her fear, her nerves, and her all-or-nothing resolve.
Saiki let out a soft mental sigh. He didn't push her away. Instead, he slid his arm around her slender waist. His other hand found the back of her neck, his fingers sliding into her brown hair to guide the clumsy kiss. He traced her lips with his tongue, coaxing her to open for him before sliding deep to tease her tongue.
Rin's body transitioned from rigid to liquid. She closed her eyes, responding with an unpracticed hunger as she surrendered her entire world to him.
The kiss lasted until Rin was gasping for air. When Saiki finally released her, she leaned into him, her eyes glazed with lust and her blush reaching down to her collarbone.
"Rin..." Saiki whispered.
Rin looked up, her gaze full of unshielded desire. Her protective shell of modesty had been completely pulverized.
"Saiki-kun," her voice was a trembling wreck, yet firm. "Take me. I love you... I want to be your woman."
The bluntness of the invitation left Saiki staggered once more. But Rin had already grabbed his hand, pulling him off the sofa and leading him toward her bedroom. Her steps were unsteady, but her direction was absolute.
The bedroom was small, tidy, and smelled of lavender and medicine. Rin closed the door and turned to face him. Then, under Saiki's stunned gaze, she began to undress.
Her fingers shook as she fumbled with the buttons of her medical uniform. One by one, her clothes hit the floor. First the jacket, then the shirt, and finally her undergarments. She didn't hesitate for a second. Despite her face being red enough to bleed, and her body quivering with shame, she stood fully exposed before him.
Her maidenly body gleamed like ivory in the afternoon sun. She wasn't fully developed yet, her beauty possessing the sharp, fragile edge of youth. Her soft breasts were modest but pert, her waist narrow, and her legs long and straight. Her hidden garden was soft and sparsely covered.
She tried to shield herself with her arms, but failed to hide the vast expanse of her glistening skin. She looked up at him with watery eyes—bashful, anxious, yet overflowing with expectation.
"Saiki-kun... do you... do you not want me?" Seeing his lack of movement, Rin's voice broke into a sob.
Saiki finally snapped out of it. Looking at this incredibly brave girl, his heart swirled with a mix of affection, pity, and a budding carnal hunger.
"No," he said, stepping forward to catch her wrists. "I love you too, Rin. But..." He paused, deciding to be blunt. "I have other women. Many of them. I don't want to hurt you."
He didn't want to lie to someone so pure. Rin's eyes flickered with sadness, but it was quickly replaced by a firmer resolve. She gently pulled her hands free and reached for Saiki's clothes. Her movements were clumsy, her fingers shaking so hard it took several attempts to unbutton his shirt. But she was focused, as if performing a sacred rite.
"I know," she whispered as she worked. Her voice was as soft as a mother soothing a child. "Saiki-kun is so amazing; of course other girls love you. It's only natural. But... I don't care. I just need you to love me back. That's enough."
His shirt was discarded, then his undershirt. When his chest was bare, Rin's face flamed hotter, but she didn't stop. She reached for his belt. Finally, Saiki was left with his last defense. Rin was too embarrassed to continue.
Looking at her mixture of shame and courage, Saiki's last doubt evaporated. He stopped talking and scooped her up. Rin let out a small cry, her arms instinctively locking around his neck. Saiki walked to the bed and laid her gently on the pink sheets.
He leaned over her and captured her lips again. This time, the kiss was deep and possessive. Rin responded with a raw intensity, her fingernails digging into his back as if terrified he would evaporate.
Saiki's hands began to roam over her naked, smooth frame—from her neck to her breasts, across her stomach, and down her thighs. His touch was magic; wherever he touched, Rin's body gave a small shiver, and her skin flushed a deeper pink.
"Mngh... Saiki-kun..." Rin let out a tiny moan, her back arching reflexively.
Saiki moved from her lips to her ears and neck before settling on her breasts. He took one pink nipple into his mouth, his tongue swirling around the tip.
"Ah...!" Rin's breathing turned into a frantic pant. She gripped the bedsheets tight.
Saiki didn't stop. He moved downward, his mouth passing her stomach to reach her moist, secret garden. Beneath the soft grass, her pink petals were already weeping with nectar, smelling of sweet youth.
"Saiki-kun... no... not there..." Rin tried to clamp her thighs shut, but Saiki gently pried them apart. He leaned down and feasted on her.
"Ahn!" Rin shrieked as a jolt of electricity shot through her spine. The sensation was entirely alien, driving her to the brink of losing her mind. Saiki's tongue explored, licked, and sucked. He could feel her body getting hotter and wetter with every second.
When he felt she was ready, Saiki finally lifted his head. He shed his final layer. The sight of his towering, hot weapon made Rin turn crimson, yet she couldn't stop herself from stealing a few wide-eyed looks.
"Rin," Saiki whispered into her ear. "It's going to hurt at first."
Rin looked at him, fear in her eyes, but her resolve remained. "For you, I'm not afraid of anything." She proactively spread her legs a fraction wider.
Saiki didn't hesitate. He knelt between her thighs, grinding and testing the entrance before pressing against her wet opening. He drove his hips forward—
"Ngh...!" Rin bit her lip, her brow furrowing as tears leaked from her eyes.
Saiki stopped, leaning down to kiss the tears away. He stroked her body gently to soothe the tension. "Does it still hurt?"
Rin shook her head, a blissful, tear-stained smile breaking across her face. "It doesn't... I'm just so happy... I love you so much..." She raised her legs to lock them around his waist, inviting him to continue.
Saiki felt a wave of tenderness. He began to move slowly, his pace controlled and gentle.
Simultaneously, he channeled a thread of pure Sage energy through their point of union into Rin's body. This wasn't standard Dual Cultivation; he was using his primordial power to soothe her meridians and nourish her cells, ensuring her first time was more about pleasure than pain.
The energy flowed through her, opening her channels and strengthening her frame. However, as the energy reached Rin's heart—
Saiki froze.
He felt it. An incredibly subtle, ice-cold mark was lurking deep within her heart. It carried no malice or destructive intent; in fact, it felt quite "gentle." Its only function was to amplify the host's emotions and desires, making them more impulsive and wanton.
But that was exactly what made it so terrifying. An "evil" seal would have triggered an alarm; a "benign" one would bypass every standard medical scan. If Saiki hadn't been using his primordial energy for a deep-tissue scan, he would never have found it.
The technique used to plant it was ancient and insidious, carrying a scent he knew all too well—a scent that made him want to vomit.
Madara Uchiha. Or rather, Black Zetsu.
Saiki's eyes turned into shards of ice.
"Saiki-kun... what's wrong?" Rin asked, sensing his sudden stillness.
Saiki looked down at the girl beneath him—at her worried gaze, her flushed face, and her pure love. He pushed down the volcanic killing intent rising in his chest and forced a tender smile.
"Nothing. You're just so beautiful, Rin."
He kissed her again, resuming his movements with even more intensity and care. But inside, his soul was roaring with fury.
Black Zetsu. Madara. You dare touch my people? You dare use a girl's purity to play your games?
Fine. Very fine.
Saiki accelerated his pace, driving deep. Rin let out suppressed moans as she buckled beneath him, her body rising and falling with his impacts. The Sage energy continued to flow, silently enveloping the curse mark. He didn't just suppress it; he ripped it from her heart, crushed it, and annihilated it in a microsecond.
Rin felt none of it. She only felt Saiki's embrace getting tighter and the pleasure becoming so intense she felt like she was melting.
When the storm finally settled, it was twilight. Rin lay in Saiki's arms, her body soaked in sweat, her face wearing a mask of exhausted bliss. Her frame was still shivering occasionally, and she felt a dull ache in her depths, but her heart was full.
Saiki stroked her back. "Better now?"
Rin nodded, a sweet smile touching her lips. "I'm perfect... Saiki-kun, I love you..." Her eyes grew heavy, her voice trailing off.
Saiki kissed her forehead. "Sleep. I've got you."
"Mm..." Rin murmured, falling into a deep sleep seconds later.
Saiki waited until her breathing was stable before withdrawing and pulling the blanket over her. He sat on the edge of the bed, watching her for a long moment. Then, he wove a hand sign, and an identical clone appeared beside him.
"Watch her," Saiki told the clone. "Stay until she wakes. Notify me of any abnormality."
The clone nodded and sat cross-legged by the bed. Saiki stood up and dressed. Every bit of his tenderness vanished the moment he finished. It was replaced by a bone-chilling, apocalyptic killing intent.
He walked out of the house and onto the darkening street. The setting sun stretched his shadow across the pavement until he looked like a demon emerging from the void.
