After a long and rigorous training session with Hakurou and his diligent students, Rin finally bid them farewell, his muscles aching but his spirit invigorated. Hakurou, ever the strict mentor, reminded him of his obligation to return before sunrise tomorrow, threatening to drag him from his bed if necessary. Rin forced a smile, a fleeting thought of regretting his pursuit of strength crossing his mind.
Returning to his tranquil riverside home, Rin carried a basket overflowing with fresh produce, gifts from the friendly residents of Tempest – mostly excess from their bountiful farms. He carefully stored the food, then, as was his custom, retrieved his fishing pole. The sun, however, was climbing high, and the increasing heat quickly deterred him. Deciding a swim was in order, Rin slipped into the cool, refreshing waters of the lake. He floated on his back, gazing up at the impossibly blue sky, a profound sense of peace washing over him. This tranquil existence, free from the complexities and burdens of his past life, was something he'd always yearned for. Yet, the insidious whispers of his burgeoning power, his awakened greed and lust, often pulled him away from such simple desires. There were moments, fleeting as they were, when he truly wished for nothing more than this quiet serenity.
After his refreshing swim, Rin decided to wash his clothes. Being alone and desiring a thorough cleaning, he opted to shed all his garments, hanging them on a line he'd strung between two trees. He had just finished the task, standing naked and unconcerned in the secluded clearing, when two piercing, womanly screams erupted from behind him.
He whirled around, his eyes widening in surprise. Standing there, blushing furiously, were Rimuru in his beautiful human form and Shuna, the elegant Kijin princess. His long, imposing private part, still exposed between his legs, was the undeniable cause of their distress. Rin, however, remained unflustered. He calmly reached for a nearby towel, wrapping it around his lower half. Shuna, meanwhile, had clamped her hands over her face, though Rin, with his enhanced vision, could clearly discern the many gaps between her fingers through which her gaze remained fixed on his exposed form. Rimuru, for his part, found himself utterly transfixed, a strange, undeniable curiosity consuming him. He couldn't help but compare Rin's impressive length to his own, a jarring thought given his past identity as a male, and he found himself unable to tear his eyes away until Rin finally covered himself.
As the towel finally concealed him, Rimuru and Shuna seemed to snap back to reality, an awkward silence settling between them. Rin, however, could still hear their thoughts, and a mischievous thrill ran through him. His covered private part, already quite substantial even in its relaxed state, began to swell and lengthen, bulging noticeably beneath the towel, as if eager to pierce someone's private depths. Rimuru and Shuna both noticed his undeniable arousal. Shuna felt a fresh wave of heat flood her cheeks, her blush deepening. Even Rimuru, whose slime body usually rendered him immune to such physical sensations, felt an inexplicable warmth spread through him.
Rin, feigning apology for his reaction, offered a quiet "Sorry about that," but made no move to conceal his burgeoning state further. Instead, he subtly accessed their status windows, his eyes widening in genuine surprise. Their sexual interest ratings were already incredibly high, far more than he had anticipated, even without any direct manipulation from him. Still, ever the opportunist, he discreetly pushed both their 'Sexual Interest' stats to a staggering 95.
Without hurrying, Rin calmly walked towards his house to retrieve some fresh clothes. As he left, Shuna and Rimuru, still flustered, caught each other's eye, then quickly looked away, an embarrassed, awkward atmosphere hanging heavily between them. Rimuru's earlier thoughts, the comparison of his own past masculinity to Rin's formidable endowment, suddenly resurfaced. A shiver ran down his spine, then slowly, thrillingly, transformed into an undeniable excitement. The urge to help Rin, to offer his body for Rin's sexual gratification, began to intensify, his love for Rin quietly growing without Rin even being aware of it.
Shuna, on the other hand, was consumed by embarrassment, yet a new thought began to take root in her mind: What if it were my turn tonight? She knew Shion had given her virginity to Rin, and a powerful, desperate desire to do the same now consumed her. Then, her gaze fell upon Rimuru, recalling his earlier reaction, and a sudden, hopeful thought blossomed. Perhaps Lord Rimuru feels something similar? It would be wonderful if my Lord served Rin alongside me. She also noticed Rimuru's attire, far more stylish than her own, and the noticeable increase in the size of Rimuru's chest.
Just then, Rin reappeared, dressed in the new clothes Shuna had given him. He thanked her for the outfit, and Shuna, still flustered, murmured that she would gladly give him new clothes every day. Now fully dressed and composed, Rin smiled politely, a genuine warmth in his tone. "So," he asked, his voice welcoming, "to what do I owe the pleasure of your visit?"
