Elias woke Lena at exactly six o’clock, his lips brushing across her face in a trail of soft, deliberate kisses that began at her forehead, lingered on her flushed cheeks, and descended with possessive intent along the delicate column of her throat. The faint stubble on his jaw grazed her sensitive skin, sending tiny sparks of awareness through her still-sleepy body. “Wake up, angel,” he murmured against her pulse point, his voice a low, velvet command that brooked no refusal. “Rise and shine. We have plans today that will not wait for lazy little girls.”

Lena stirred beneath the silken sheets, her dark, lustrous curls splayed wildly across the pillow like spilled ink. At twenty, her body remained a vision of soft, feminine perfection—full, generous breasts rising and falling with each breath, the swell of her hips and the rounded curve of her bottom a constant temptation beneath the thin fabric. She blinked up at him through heavy-lidded blue eyes, still heavy with dreams. “Hmm ... Master ... please ... just a little longer...”

“My sleepy beauty,” Elias replied, his tone gentle yet threaded with unyielding authority. He kissed her eyelids, her cheeks, and finally claimed her mouth in a slow, deep kiss that stole what little breath she had left. His large hand slid beneath the sheets to cup one full breast, thumb brushing the peak until it tightened beneath his touch. “Wake up for me, little one. I have waited long enough.”

After several more minutes of tender coaxing—kisses interspersed with firm caresses that left her skin tingling and her core warming—Lena finally sat up, cheeks flushed and curls tousled. Elias’s gray eyes lit with open delight and raw possession as he drank in the sight of her. “That’s my lovely bride-to-be,” he said, pride thickening his voice. He pulled her to her feet with effortless strength, drawing her close so her soft curves pressed against his hard frame. “Come here, my love.”

He wrapped her in a luxurious, floor-length robe of the softest cashmere, the fabric whispering against her bare skin. Lena touched it dreamily, still half-lost in the haze of sleep. “Master? A robe?”

“It is close enough for now, my sweet slave,” he answered, his hand settling possessively on the curve of her bottom, squeezing gently as he guided her forward. “You will not need much clothing today.”

They moved through the estate’s opulent corridors, Elias’s palm never leaving her ass—stroking, kneading, occasionally delivering a light, proprietary pat that made her gasp softly. The touch was both comforting and arousing, a constant reminder of ownership. They passed heavy oak doors and entered a space that stole the breath from Lena’s lungs.

The indoor pool was nothing short of a godlike marvel, an engineering masterpiece that blended cutting-edge technology with sensual luxury. Vast curved walls of intelligent glass could shift from crystalline transparency to deep obsidian at a whisper, while bioluminescent veins pulsed along the edges like living veins of starlight. The water itself glowed with a therapeutic turquoise that shifted hues according to the mood Elias programmed—soft and inviting now, promising warmth and safety. A heated jacuzzi curved gracefully along one side, its jets and bubble chambers adorned with intricate patterns. Floating saunas hovered like elegant glass orbs filled with scented steam, and sunken meditation alcoves offered floating cushions beneath mood-light panels. The entire sanctuary was temperature-controlled to perfection, humidity balanced like a lover’s breath, silent save for the gentle lap of water against warm marble.

Lena stared, awestruck, her generous breasts rising faster beneath the robe. “It’s ... incredible here, Master. I’ve never seen anything like it.”

Her eyes drifted to the deep end, where the water deepened far beyond her waist. Her stomach twisted with sudden anxiety. “I don’t know how to swim,” she admitted regretfully, voice small and sad.

Elias’s expression softened with protective tenderness, but a stern undercurrent remained in his steel-gray gaze. He stepped closer, both hands claiming her bottom fully now, squeezing the soft, rounded flesh with deliberate possession. “I know, sweetness. I know every detail about you.” He leaned down, kissing her temple with surprising gentleness. “I will teach you myself. Thoroughly.”

Lena’s eyes shone with tentative hope. Elias was the best teacher imaginable—his methods strict, his care absolute. Yet she feared the intensity he brought to every lesson. He began untying her robe with slow, masterful fingers, pushing the fabric off her shoulders until it pooled at her feet, leaving her gloriously naked before him. His own clothes followed, revealing the powerful, sculpted body of a man who commanded life with scalpel and will. He stood naked and unashamed, his thick cock already half-hard at the sight of her.

“Master ... how did you know I couldn’t swim?” she whispered as he led her to the edge.

He smirked, dark and satisfied, guiding her into the warm water. “Because, my love, I was the one who forbade it for you all these years.” His hands never left her—stroking her waist, cupping her full breasts as the water rose to her thighs, thumbs circling her nipples until they pebbled. “You belong in the water only when I deem you ready. Only when I am here to keep my little girl safe from drowning.”

Lena shivered as the water embraced her, its warmth seeping into her bones. Elias lifted her effortlessly, pressing her back against his broad chest so every inch of her naked body molded to his. His cock nestled hot and heavy between her thighs, brushing her slick folds with each subtle movement. One arm banded around her ribs, just beneath her breasts, while his free hand roamed—squeezing her bottom, tracing the cleft, occasionally dipping between her legs to stroke her clit with feather-light touches that made her whimper.

“Begin with the basics, my bride-to-be,” he murmured against her ear, voice low and dominant. “Arm circles first. Slow and controlled. Feel the water resist you—let it teach your body strength.”

He demonstrated by guiding her arms in wide, graceful circles, his chest pressed firmly to her back, his hips rocking subtly so his cock slid along her slit without entering. Every circle brought her breasts into fuller contact with his forearm, nipples dragging against his skin. Lena moaned softly, the pleasure of arousal building as the water buoyed her, making her feel weightless and utterly at his mercy. “Master ... it feels ... so different. So good...”

“Flutter kick now,” he commanded, shifting her higher in his arms so her legs dangled.

Lena began laughing in happiness.

He parted her thighs with his own powerful legs, holding her open while demonstrating the gentle, rhythmic motion. His hand slid down to knead her bottom cheeks, spreading them occasionally so the water teased her most private places. “Kick for me, little one. Feel how the water supports you—how I support you.”

Lena obeyed, her legs fluttering in small, trembling circles. Joy sparkled in her eyes, pure and bright, but Elias ensured the lesson remained laced with dominance. He pinched one nipple firmly, rolling it between thumb and finger while praising her. “Good girl. Harder kicks. Arch your back—yes, just like that.” His cock pressed insistently against her entrance now, not thrusting but teasing, sliding along her wetness as she moved. The combination of weightless freedom and his relentless touching left her panting, aroused beyond reason, her body humming with need even as she learned proper form.

They progressed slowly, masterfully. Elias kept her body glued to his—hands everywhere, stroking her breasts until they ached with sensitivity, spanking her bottom lightly underwater when her form faltered, the sharp smacks muffled yet stinging deliciously. “Focus, slave,” he growled lovingly, delivering three firm swats to her ass that made her cry out and clench around nothing. “A proper stroke requires discipline. Your body is mine to teach.”

Lena’s laughter rang out—bright, free, and utterly his—as she managed her first independent flutter across a shallow section, Elias’s hands never far, cupping her breasts from behind, pinching, rolling, keeping her on the edge of orgasm. “I’m doing it, Master! I’m really swimming!”

“Beautiful,” he praised, turning her in the water to face him. His eyes burned with dark hunger. “One final movement, my little slut. The most important one.” He grabbed her hips, pressing her back against the smooth pool wall. “Spread your legs wide. Arms behind my head. Do not move unless I allow it.”

Lena obeyed, heart pounding, legs parting until she was open and vulnerable. Elias thrust into her in one brutal, claiming stroke, burying his thick cock to the hilt. The water amplified every sensation—the stretch, the fullness, the slick slide. Lena screamed, a broken sound of pleasure and overwhelm.

“Yes,” Elias snarled, voice rough with dominance. “This is how your Master teaches you to take the deep end.” He fucked her with slow, powerful thrusts at first, water slapping around them, one hand spanking her exposed bottom hard between strokes—sharp, stinging smacks that turned her cheeks pink beneath the surface. “Feel the burn, little girl. Pain and pleasure together. That is how you learn to swim in my world.”

He groped her breasts roughly, pinching nipples until she sobbed, then soothed them with his mouth while driving deeper. The mix was devastating—rough thrusts that bordered on pain, loving caresses, dominant commands whispered against her skin. “Come for me, slave. Milk my cock while I spank this perfect ass.”

Lena shattered hard, screaming his name as orgasm crashed through her. Elias didn’t stop—fucking her through it with relentless intensity, spanking her bottom red, biting her shoulder possessively. Only when she was a trembling, weeping mess did he find his own release, flooding her deep with thick pulses of cum.

He held her afterward, gentle now, carrying her from the water like the precious treasure she was. Wrapped in a fluffy robe, he settled her on a soft sofa beside the pool and fed her by hand—fresh cherries, cool water, bites of melon—his fingers lingering on her lips. “Open, my love. Every drop. You did so well today. My perfect bride-to-be. My eternal slave.”

Lena accepted each offering with hazy, adoring eyes, the lesson etched into her body and soul.

“Master ... please can I ask something?”

“Of course, sweet slave. You can ask me anything.”

Lena hesitated, then asked the question that had been burning in her mind since the moment she saw the English girl’s file.

“I want to talk to that girl you told me about in London. The one who was ten...”

Elias stopped dead in his tracks, eyes widening in pure, terrifying horror.

“What?” he snarled, voice low and venomous. “Did you just ask me if you can meet that murderer?”

Lena was startled. She had never seen him react like this. He was always so perfectly collected, always her safe place. Now he looked ready to destroy the world.

“Ask again?” he demanded, grip tightening on her bottom.

Despite the fury in his eyes, she gathered every scrap of courage she had left.

“Please, Master ... I only want to meet her for a few minutes. I think I can reach her. I think I can help her...”

Elias was silent for a long moment, carrying her back toward their bedroom. She could feel his fury through the synesthesia — deep, dark reds and blacks swirling around him like storm clouds.

He stepped into their bathroom, discarded the blanket he had wrapped around her, and placed her on her feet under the warm shower. When she swayed, he caught her gently and leaned her back against his chest.

Lena was amazed. Despite his anger, he was so gentle with her.

He began washing her quickly and thoroughly, his hands gliding over every inch of her body. She was aware of his hard cock pressing against her bottom, how could he be hard again after only a few minutes of their fucking?

“You know, my love,” he said as he started drying her body, voice low and dark, “this beautiful mouth of yours should be wrapped around my cock twenty-four hours a day so that it can never say such blasphemy again.”

“Master ... please ... just this one. I might be able to help that kid...”

“Do you know how destructive the mind of that girl is?” he asked, voice suddenly cold. “She is a murderer who killed three other children. She is not an innocent child.”

Lena’s eyes filled with fresh tears.

“Master ... please ... if you just bring her here, I only want a few minutes...”

Finishing her drying, he took her in front of the dresser. To her surprise, he selected a set of beautiful white lace underwear and slowly dressed her, managing to touch her everywhere again. He even kissed her shoulders and back while he clothed her.

When she was already horny again, he dressed her in a cute pink light summer dress that hugged her curves. Then he sat her down to brush her long hair with gentle, loving strokes.

“My parents arrive tonight.”

Lena’s hands stilled in her own hair. She looked up at him, heart suddenly racing with nervous excitement.

“Tonight?” she whispered.

Elias smiled, but his eyes were still stormy with the fury he had felt earlier.

“Yes, tonight,” he said, voice calm but absolute.

Lena nodded, her eyes shining with a mixture of fear, love, and the strange, dangerous comfort only he could give her.

Elias finished brushing her hair with slow, deliberate strokes, each pass of the brush through her dark, lustrous curls a quiet assertion of ownership. The bristles moved like a lover’s fingers, gentle yet commanding, taming the wild spirals into elegant waves that framed her beautiful face. Lena sat before the ornate dresser mirror, her body still humming from the shower and the claiming that had preceded it. The pink summer dress he had chosen hugged her curves with exquisite precision—light fabric clinging to the generous swell of her breasts, nipping in at her waist, and flowing softly over the rounded perfection of her bottom. Beneath it, the white lace underwear he had selected felt like a second skin, delicate and sensual, a constant whisper of his taste against her most intimate places.

As he worked the brush through her hair, Lena’s voice came out soft, hesitant. “Master ... what’s your parents like?”

She remembered the first time they had spoken of them after surgery when he was feeding her—Elias mentioning they lived in Switzerland, the quiet distance in his tone. Clara had spoken of them too, with a mixture of fondness and careful omission. Elias’s hands paused for the briefest moment, then continued their rhythmic strokes.

“Well ... they are good parents,” he said, voice calm and measured. But there was a subtle shift in the air, a strange vibe emanating from him—something unresolved, like a shadow lingering just beneath the surface.

“But...?” Lena pressed gently, her blue eyes meeting his in the mirror.

He looked into the distance for a moment, the brush moving slower now. “They were not observant enough.”

Lena was confused. Surely they were very good parents for having raised a son as successful as him. “Why, Master?”

Elias’s gaze remained distant, stormy with old pain. “I was away from home those years—conferences, schools, hospitals. They were alone with Liz. They should have noticed her getting sick sooner.”

Now Lena was bewildered. He blamed his parents for what happened to his sister. “You mean she was sick before they noticed?”

“They should have notified me sooner,” he continued, voice low but edged with something sharper. “They are not doctors ... but still, they should have noticed her tiredness, her pallor, the way she faded. I could have done something. I could have changed the course.”

Lena’s heart ached for him. She knew, from fragments he had shared and from the first days in his office when she had overheard him speaking with Clara, that part of his craving for control stemmed from what happened to Liz. He still believed, deep down, that he could have saved her if only he had been there—if only someone had noticed sooner.

“Master, her disease was leukemia,” Lena said softly, her voice filled with compassion. “That’s not very noticeable before the symptoms appear. You couldn’t have known.”

“Or maybe I should have insisted on regular check-ups for her,” he replied, the brush still moving through her hair with mechanical precision. “Anyway ... she slipped through my fingers.”

Lena’s eyes met his in the mirror, her body shaking slightly at the intensity she saw there—the raw, unrelenting grief mixed with the iron will that had built an empire. “Master, that was not your fault. Or anyone else’s fault.”

He looked at her with such intensity that the air between them thickened. “It was, to a degree. But don’t worry, my love. I won’t repeat that mistake.”

And with that, both his palms landed firmly on her huge breasts, cupping them possessively through the thin fabric of the dress. Lena shuddered, a sharp gasp escaping her lips as his fingers kneaded the soft, heavy flesh. She knew exactly what he meant. Twenty-four-hour control of her body. He had not replaced her anal plug after the incident with Viktor and Samantha—after she had pulled it out herself in her desperate bid for freedom. She wondered what plan he had in his complex brain. Anything it was, she would not enjoy it.

Elias’s hands continued their slow, deliberate exploration, thumbs brushing over her nipples until they hardened into tight peaks beneath the lace and fabric. “You will be watched, Lena. Protected. Every moment of every day. No more risks. No more running. You are mine to keep safe, even from yourself.”

Lena’s breath hitched, her body responding despite the fear twisting in her chest. His dominance was absolute, elegant in its cruelty and love. The arrival of his parents loomed like a new chapter in the intricate web he had woven around her life. She leaned back against him, caught between resistance and the terrible, addictive pull of surrender.
