The first light of dawn, soft and pale, painted the interior of Rin's riverside house in Tempest. For Rimuru, waking up felt both intimately familiar and profoundly alien. Her eyes fluttered open, adjusting to the gentle illumination, and then she saw him—the man slumbering peacefully beside her, his breath a soft rhythm against her ear. A warmth spread through her chest, entirely separate from the morning chill, and a quiet, undeniable truth settled in her heart: this was Rin. And just as undeniable was the fact that she now thought of herself as 'her.'
A small, contented sigh escaped her lips. She had changed. Irrevocably. The genderless existence, the masculine form of her past life—all of it felt like a distant dream, an echo from a forgotten age. Now, she was a woman, soft curves, blossoming desires, and a heart overflowing with a love so potent it stole her breath. She didn't regret it. Not for a single moment. How could she, when this transformation had led her directly into the arms of Rin?
As she gazed at his sleeping face, a serene smile gracing her features, Rimuru felt a warmth spread through her. Sometimes, a fleeting thought would surface, an almost comical realization of how utterly 'womanly' she had become. The words she had gasped to Rin, the way her body had moved, had responded to him—begging to be ravaged, parting her legs voluntarily, driven by an instinct she never knew she possessed. It was crazy, truly, but the sheer ecstasy of it erased any lingering doubt. She would do it again, a thousand times over, just to feel him inside her, filling her, completing her.
She gently extricated herself from his embrace, careful not to wake him. The kitchen called, and an unfamiliar, yet pleasant, domestic urge stirred within her. By the time Rin's eyes slowly opened, blinking against the new day, the tantalizing aroma of a freshly cooked breakfast filled the air.
He stretched, a low groan escaping him, and then his gaze landed on Rimuru. She was at the stove, humming softly as she flipped something in a pan. The simple clothes she wore, a plain blouse and a flowing skirt, seemed to cling to her voluptuous figure in all the right places, making her look not just womanly, but undeniably sexy, like the quintessential 'wife material.' It was almost impossible to reconcile this vision with the existence of a former slime, a genderless being who had once been a Japanese salaryman.
Rin couldn't hold back. He rose from the bed, his movements quiet, and wrapped his arms around her from behind, pulling her flush against his bare chest. Rimuru gasped, surprised, but a soft smile touched her lips as she leaned into his embrace, accepting the warmth of his body. But Rin wasn't content with just a hug. His lips trailed down her neck, leaving a path of light kisses that made her giggle, a delightful tickle spreading through her. His hands, no longer restrained, found their way to her sensitive breasts, gently cupping and caressing.
Rimuru knew Rin's stamina, his almost terrifying endurance. And despite her own formidable strength surpassing him, when Rin started pushing his rod inside of her, she was nothing more than a normal woman, exquisitely susceptible to his desires. And that, of course, was precisely what happened. As the scent of their breakfast mingled with the rising heat of their passion, Rin, ever the pragmatist, made sure they got their 'morning exercise' in.
A week later, after a sweet, peaceful, and utterly pleasurable sojourn in the world of Tensura, Rin felt the familiar pull of home. With a sigh of contentment, he decided it was time to return to the DXD world.
The transition was seamless, instantaneous. And just as expected, the very first thing he registered upon waking was the familiar warmth around his groin, the soft, insistent tugging sensation. Ai. She was there, her head nestled between his thighs, her lips working diligently, sucking on him as if he were the most delicious thing in the world. Rin's eyes flew open just as a wave of intense pleasure washed over him, and he climaxed instantly, releasing himself into her eager mouth.
Seeing Ai's face, her soft cheeks now glistening with his semen, a primal urge surged through him. He couldn't hold back. He moved, pulling her up, flipping her over, and began to ravage her. Ai gasped, a small plea escaping her lips, but her eyes, wide and dilated, told a different story. They were hungry, demanding, clearly wanting more. Seeing that barely suppressed desire ignited an even greater excitement within Rin. He grinned, a predatory gleam in his eyes, and made sure Ai received her 'punishment' in full.
Later that morning, Rin found himself once again ensconced in the familiar confines of Kuoh Academy. The rhythmic drone of the teacher's voice, the mundane lessons—it was all so dreadfully boring. If not for his Tier III maxed intelligence and wisdom, he probably wouldn't have bothered excelling. As it was, he was an effortlessly brilliant student, a fact that only added to his already overwhelming popularity.
Lunchtime arrived, and Rin considered paying a visit to Sona in the student council room. He peeked through the slightly ajar door, only to see her surrounded by her peerage, all engaged in lively conversation as they ate. It wouldn't have been out of place for him to join them, but a subtle sense of timing told him there would be a better moment, a more opportune space, to tease her later. With a mental shrug, he decided to leave them to their meal.
Just as he was about to head towards the Occult Research Club, his phone vibrated. A message from Rias: "We're currently hunting a stray devil. It's attacking people in the middle of the day so we're not in the club."
Seeing the urgency of the context, Rin altered his plans. Instead of the club, he opted for the cafeteria. He grabbed a tray and found an empty table, settling down to eat alone. It wasn't long before several girls, emboldened by his solitary presence, began to approach his table, their smiles hopeful. Rin, ever polite, gently refused their invitations, citing a need for quiet reflection.
Despite his rejections, an odd phenomenon occurred. The girls didn't appear dejected, nor did any hint of animosity or hatred cloud their faces. For them, Rin was like a distant, unattainable star, shining brightly in the night sky. They, mere humans, were simply content to gaze upon his brilliance from afar, accepting his quiet refusals with a certain grace. Rin was keenly aware of his popularity, a consequence of his heightened charm. His looks were already far above average, but coupled with his status as a rich kid and the constant presence of stunning girls like Rias and Akeno in his orbit, he had become a veritable prince charming, easily surpassing Kiba's legendary popularity.
After politely declining yet another small group of girls eager for a moment of his attention, Rin was genuinely surprised. Approaching his table, her steps hesitant but determined, was Kiryuu. She paused, her eyes meeting his. "Excuse me, Takakura-kun," she began, her voice soft, "may I… may I eat here?"
A genuine smile touched Rin's lips. He gestured to the empty seat opposite him. "Of course, Kiryuu-san," he replied, his voice warm and inviting. "It would be my pleasure."
