The twilight in the Royal Capital of Meridiana was a thing of liquid gold, pouring through the leaded glass windows of the spacious apartment and setting the dust motes dancing like tiny fairies. For Kazuki Tanaka, a man of around forty whose isekai tsuuhan business had unexpectedly flourished, this quiet hour was his favorite. The cacophony of the otherworldly market below had faded, replaced by the gentle clinking of porcelain and the soft, contented sighs of the three women who had come to define his new life. The air was thick with the scent of jasmine from the tea Primula Mallow had ordered for him last week and the lingering, sweet aroma of the pastries Myaley had just baked. It was a domestic paradise, a world away from the corporate grind of his past life, and it was in these moments that he felt the profound, almost surreal depth of his connection to them.

Primula, the elegant and sharp-witted merchant princess, sat across from him, her lavender eyes soft in the fading light. She swirled the amber liquid in her cup, a rare tea from the Eastern Continent his online shopper system had miraculously procured. "Another successful day, Master Kazuki," she murmured, her voice a low, melodic hum that never failed to stir something deep within him. "The demand for those 'self-heating kotatsu' is unprecedented. You've single-handedly revolutionized how the nobility will endure the winter." Her gaze lifted from her cup to meet his, and in its depths, he saw not just professional admiration, but a warmth that made his heart beat a little faster.

"It was your distribution network that made it possible, Primula," Kazuki replied, his voice a low rumble that felt comfortable and earned. At his age, he found no need for false modesty, only genuine gratitude. "Without your connections, my little around 40 otoko no isekai tsuuhan venture would still be a cart in the bazaar." He reached out, his fingers, calloused from unpacking countless crates yet still gentle, brushing against hers as he took the teapot to refill her cup. The brief contact sent a visible shiver through her, a slight blush creeping up her neck.

From the plush rug by the hearth, Myaley, the fiercely loyal and unexpectedly domestic beast-girl, looked up from her sewing. Her feline ears twitched, and her tail gave a lazy, contented flick. "Master Kazuki works too hard," she chimed in, her voice bright and earnest. "He needs to be taken care of. That's why I made these meat buns! And why Azalea is giving him a foot rub!" She nodded towards the third member of their unusual household.

Azalea, the quiet and intensely focused elf alchemist, was indeed kneeling on the floor beside Kazuki's armchair. Her long, silver hair was tied back, revealing the elegant points of her ears, which were tinged a delicate pink. Her slender, powerful hands were working the sole of his foot with a practiced precision that made him groan in quiet appreciation. "Muscle tension is a common ailment for those who stand for long periods," she stated, her tone clinical though her actions were anything but. "The application of this salve, infused with moonpetal and warmroot—ingredients your 'online shopper' service provided—will increase blood flow and promote relaxation." Her green eyes, usually so analytical, flickered up to his face, checking his reaction, seeking his approval.

Kazuki leaned back, letting the sensation wash over him. This was his life now. No longer was he just a middle-aged online shopper in another world; he was their anchor, their provider, and though he dared not always admit it, the object of their shared affection. He saw it in the way Primula's professional demeanor melted away when they were alone, in the way Myaley preened at his slightest compliment, in the way Azalea's scientific explanations often faltered under the weight of her own burgeoning feelings. The romantic tension in the room was a palpable force, a fourth presence weaving between them, as warm and enveloping as the twilight itself.

"You all take such good care of me," he said, his voice thick with an emotion he couldn't name. "I'm a very lucky man."

Primula set her cup down with a definitive click. The sound broke the tranquil silence, heralding a shift in the atmosphere. She rose, her movements fluid and deliberate, and walked around the low table until she stood before his chair, looking down at him where Azalea still tended to him. "Luck had little to do with it, Kazuki," she said, her voice dropping to an intimate whisper. "You built this. You saw value in us, not just as business partners or employees, but as women. You provide for us, protect us, and you treat our dreams and desires with a respect no man in this world ever has."

Myaley was on her feet in an instant, padding over to join Primula, her tail now swishing with nervous excitement rather than contentment. "She's right, Master! You're kind and strong and... and..." She bit her lip, struggling for the words.

"Desirable," Azalea finished softly, her hands stilling on his foot. She looked from Primula to Myaley, a silent communication passing between the three of them before she too rose, standing with them, a united front. "Our data, our observations... and our hearts... are in unanimous agreement."

Kazuki's breath caught in his throat. The three most beautiful women he had ever known were standing before him, their expressions a mixture of vulnerability and fierce determination. The carefully maintained boundaries of their master-servant, business-partner relationships were evaporating before his eyes, leaving only raw, honest need in their wake. This was the ultimate fantasy of any around 40 otoko no isekai tsuuhan, yet it felt terrifyingly, wonderfully real.

Primula was the first to move. She leaned down, her lavender hair brushing his cheek, and captured his lips in a kiss that was anything but tentative. It was a claiming, a confession years in the making, filled with the passion of a merchant princess who had finally found her most treasured possession. Her taste was of expensive tea and ambition, and Kazuki responded instinctively, his hands coming up to cradle her face, pulling her deeper into the kiss.

When they finally parted, both breathless, Myaley didn't hesitate. With a happy, eager sound, she practically launched herself into his lap, wrapping her arms around his neck and pressing her soft, generous body against his. Her kiss was sweet and enthusiastic, tasting of sugar and sunshine, and her tail wrapped possessively around his arm. "My turn! I've wanted to do that for so long!" she giggled against his mouth.

Azalea watched, her green eyes wide and dark with desire. Her scientific composure had completely shattered, leaving behind a woman trembling with newfound hunger. Slowly, she knelt before his chair again, but this time her hands went to the laces of his trousers. "I wish to conduct a new experiment," she whispered, her voice husky. "I hypothesize that tactile stimulation applied to certain... erogenous zones... will produce a far more profound physiological response than a foot rub."

Kazuki could only moan his assent as Primula's clever fingers began to unbutton his shirt, her lips tracing a hot path down his neck, while Myaley nuzzled against his chest, her purr a low vibration against his skin. Azalea's hypothesis was proven devastatingly correct the moment her cool, delicate fingers wrapped around his aching length, already hard and straining. Her touch was inquisitive at first, then grew confident, stroking him with a rhythm that made his hips buck involuntarily.

"The data is... very promising," Azalea breathed, her academic facade crumbling completely as she leaned forward and took him into her mouth. The sensation was electric, a bolt of pure pleasure that shot straight to his core. Her silver hair spilled over his thighs as she worshiped him with a fervor that was both innocent and deeply skilled, her tongue tracing every sensitive ridge and vein.

Primula and Myaley exchanged a look of heated agreement over his shoulder. Together, they helped him from the chair, guiding him towards the large, plush bed that dominated the adjoining room. Clothes became a forgotten hindrance, discarded in a trail of eager hands and soft laughter. The golden twilight had given way to a deep indigo night, and the moon now cast its silvery glow upon them, illuminating the breathtaking canvas of their bodies.

Kazuki laid back against the pillows, a king in his domain, as his three devoted attendants descended upon him. Primula, her aristocratic grace replaced by a primal need, straddled his hips, guiding him into her wet, welcoming heat with a deep, throaty cry of fulfillment. She rode him with a slow, grinding rhythm, her head thrown back, her perfect breasts offered to the moonlight. Myaley, ever eager to please, knelt beside them, her mouth latching onto one of Primula's peaked nipples, laving and suckling while her hand found its way between her own thighs, stroking herself in time with Primula's movements.

Azalea, not to be left out, curled herself beside Kazuki's head, her fingers tangling in his hair as she brought her own damp, glistening core to his mouth. "Please," she begged, all pretense of analysis gone, replaced by pure, unadulterated need. "Sample me. I need to know your taste." He needed no further invitation. His tongue delved into her sweet, tight folds, licking and sucking at her sensitive nub until her thighs trembled around his head and her cries joined the symphony of their passion.

The room filled with the sounds of their union: the slick, rhythmic slap of skin against skin as Primula impaled herself on him again and again; Myaley's breathy, wanton moans as she fingered herself to the sight; Azalea's escalating, keening whimpers as his tongue drove her closer to the edge; and Kazuki's own guttural groans of pleasure, a man utterly consumed by sensation. He was the center of their universe, the mature man from another world who had provided them with everything, and now they were returning the favor a thousandfold.

Primula was the first to shatter, her inner walls clenching around him like a velvet vise as she cried out his name, a sound of pure, unbridled ecstasy that seemed to shake the very foundations of the apartment. Her climax triggered his own, and with a roar, he spilled himself deep inside her, his release seemingly endless, a torrent of pent-up desire and affection. The force of it pushed Primula over into another, smaller orgasm, and she collapsed forward onto his chest, breathless and sated.

But the night was far from over. Myaley, whining with need, immediately took Primula's place, sinking down onto his still-hard length with a cry of relief. Her inner muscles were different, tighter, and her movements were less controlled, a frantic, joyful bouncing that spoke of her animalistic passion. Azalea, having recovered from her own powerful climax under his ministrations, moved to kiss Primula deeply, their tongues dueling as they shared the taste of him and each other, their hands roaming over each other's bodies.

Kazuki watched the breathtakingly erotic scene through half-lidded eyes, his hands gripping Myaley's hips, helping her find her rhythm. He felt a power and vitality he hadn't known since his youth, a profound connection that went beyond the physical. This was the true reward of his around 40 otoko no isekai tsuuhan life—not the wealth, but this deep, abiding love and devotion. He flipped Myaley onto her back without ever leaving her warmth and drove into her with renewed vigor, making her scream his name to the ceiling as her climax ripped through her.

Finally, he turned to Azalea, who looked at him with wide, worshipful eyes. He entered her slowly, reverently, watching every micro-expression of pleasure cross her beautiful face. Her legs wrapped around his waist, pulling him deeper, and she whispered a stream of erotic, scientific observations that somehow were the most arousing thing he had ever heard. "Friction coefficient is... optimal... depth of penetration is causing a pleasurable pressure on my anterior fornix... please, Master Kazuki, continue the experiment..." He did, until she too was a quaking, pleading mess beneath him, her third orgasm of the night leaving her boneless and blissful.

They lay together in a tangled, sweaty, sated heap of limbs, the moonlight painting their bodies in shades of silver and blue. The kotatsu hummed softly in the other room, a testament to the daily life of a middle-aged online shopper in another world, but here, in this bed, was his true home. Primula's head was on his shoulder, Myalea was curled against his side, her tail draped over his leg, and Azalea lay with her cheek on his chest, listening to the steady, strong beat of his heart.

"We belong to you, Kazuki," Primula whispered into the quiet darkness, her voice filled with a peace he had never heard before. "Your merchandise brought us comfort, but your heart brought us together."

Myaley nuzzled closer. "And we'll never let you go."

"The data is conclusive," Azalea murmured, already half-asleep. "This arrangement results in a one hundred percent increase in overall happiness metrics."

Kazuki held them all tighter, pressing a kiss to each of their foreheads in turn. He was no longer just a transporter of goods; he was the anchor of their hearts, the mature man who had found his ultimate delivery in the arms of Primula Mallow, Myaley, and Azalea. His isekai tsuuhan had delivered him not just a new business, but a love more profound and passionate than any fantasy, a romance built on mutual respect that had finally, beautifully, burst into flame.
