Later that evening, back in their bedroom, Elias granted one small mercy.
Clara was allowed to visit.
Lena was already under the silk sheets when the older woman entered, per Elias’s strict orders. She sat up carefully, clutching the fabric to her chest.
Clara’s face softened the moment she saw her. “How are you, child?”
The simple warmth in her voice broke something inside Lena. She reached out, and Clara moved forward, pulling her into a gentle embrace. Lena clung to her tightly, burying her face in the familiar scent of lavender and home.
“I missed you,” Lena whispered, voice cracking. “So much.”
Clara held her for a long moment before pulling back, brushing a strand of hair from Lena’s face with maternal tenderness.
Lena’s eyes filled with desperate hope. “Clara ... please talk to him. About Samantha and Viktor. About what he’s planning. I’m scared of what he might do to them.”
Clara shook her head slowly, her expression heavy with sorrow.
“I’ve never seen him like this, Lena. Not even after Liz. He’s ... different with you. More intense. More dangerous. I’ve tried speaking with him, but his mind is made up. And honestly?” She sighed. “What you did was dangerous. Reckless. You put yourself in harm’s way when you could have simply called him.”
Lena’s throat tightened. “I know ... but Clara, I had to. That woman — Samantha — she intended real harm to Elias. I felt it. The hatred, the planning ... I thought if I didn’t follow her right then, I might lose the chance. Or Elias might not find her in time.”
Clara looked at her with deep, knowing sadness.
“You nearly got yourself killed. My dear ... you are playing with fire. Elias loves you in a way that consumes everything. Including himself. Be careful, Lena. Please.”
“Clara ... where are Viktor and Samantha? What is he doing to them?”
Clara let out a slow, heavy sigh. She reached out and gently took Lena’s hand, her touch warm and maternal.
“I don’t know, child. Truly. Elias doesn’t speak to me about those kinds of things. Only he and Roger know where they are being kept. He keeps that part of his world locked away from me.” Lena nodded, tears slipping down her cheeks as she held Clara’s hand tightly. The weight of her choices, the fear of what was coming, and the strange comfort of being back in Elias’s world pressed down on her all at once.
“Please ... talk to him. I’m scared of what he might do to them. He’s so angry, Clara. I can feel it. It’s darker than anything I’ve ever sensed from him before. I don’t want him to become a monster because of me.”
Clara studied her for a long moment, her expression heavy with concern. Then, in a quiet, worried voice, she asked, “Has he punished you for what you did?”
Lena shook her head, tears shimmering in her eyes.
“No ... he hasn’t. Not yet. And that worries me even more. He’s holding it back. I can feel it in him.”
Clara nodded slowly, her face shadowed with quiet understanding. She leaned forward and pressed a gentle kiss to Lena’s forehead.
“I will talk to him soon, my dear. I promise. Just try to rest now.”
With that, Clara stood, giving Lena’s hand one final squeeze before quietly leaving the room. As the door closed behind her, her expression grew resolute.
She needed to speak with Elias — and soon.
Elias stood just outside the door, listening in silence, his expression unreadable as the two women spoke. His rage had not faded. It had only been buried beneath layers of icy control.
For now.
Lena remained alone in the bedroom, the weight of everything pressing down on her. The silence felt heavier than ever. She touched her throat, her collar was no longer there. What had happened to it? She wondered.
Roger Bennett stood in the shadows of the command center, arms crossed.
He had been the first through the door when they raided the abandoned estate. The sight that greeted him had stopped his heart cold.
Lena lay unconscious on the cold floor of the lab, blood pooling beneath her. For one horrifying second, Roger had thought she was dead. The fear that gripped him in that moment was unlike anything he had ever experienced — sharper than any battlefield, deeper than any mission gone wrong. In that split second, he understood exactly why Elias had become the man he was. Lena wasn’t just a girl to him. She was the axis around which his entire world turned.
That fear had quickly turned to fury.
Samantha and Viktor Lang had done this. They had tried to take her from Elias. They had nearly succeeded.
They deserved everything that was coming to them.
Elias had not yet decided the full extent of their punishment. In the hours after Lena was safely back in the hidden medical chamber, he had pulled Roger aside, voice rough with barely contained emotion.
“I need time,” he had said. “I need to come out of this shock first. Make sure they’re secure. Keep them alive and conscious. But do not begin until I say so.”
Roger had followed those orders to the letter.
He had overseen their transport to the secure underground facility, ensuring they were separated, sedated just enough to keep them compliant, and placed under constant surveillance. He had handled the legal side with ruthless efficiency — forging documents, paying off the right officials, and creating a paper trail that made their disappearance look like a simple flight from justice.
Fortunately, even the CIA had wanted Viktor Lang. When Roger’s team swept the abandoned estate, they discovered a treasure trove of other deadly viruses and bioweapons research. A quiet deal was struck. In exchange for enough evidence to bury Lang in federal charges, the agency agreed to look the other way on whatever Elias chose to do with him privately. The FBI followed suit. As far as the official record was concerned, Viktor Lang and Samantha Davis had simply vanished after a failed attempt on a high-profile target.
No one would come looking.
Samantha and Viktor had tried to kill Lena.
For that, they would suffer in ways the world would never know.
Roger would make sure of it. When Elias finally gave the word, he would carry out every order without hesitation or mercy.
Because in the end, his loyalty was absolute.
And Lena Voss was the only thing that truly mattered.
The hunt had only just begun. And Roger Bennett was ready to make it hurt. Elias entered the bedroom without a word, crossing the space in long, purposeful strides. He drew back the covers and lifted Lena’s naked body into his arms, carrying her as though she were something both precious and entirely his.
“Master ... I can walk,” she murmured, still hoarse from the days of isolation.
“Not yet,” he replied, his voice firm but edged with exhaustion. “You’ve done enough walking for now.”
He set her down gently in the bathroom and turned on the shower, warm steam filling the air. Elias undressed with deliberate calm, revealing the powerful lines of his body. Lena’s eyes widened at the sight of his thick, hard cock, already heavy with need.
“Come here,” he said quietly.
He guided her under the cascading water and pulled her close, pressing her bare body flush against his. For a long moment, he simply held her, arms wrapped tightly around her waist, face buried in the curve of her neck. A deep, weary sigh escaped him, carrying the weight of days of unrelenting worry.
Then his hands began to move.
He washed her with meticulous care at first — slow strokes across her shoulders, down her back, over the curve of her waist. But the touch gradually shifted. It became insistent. Possessive. There wasn’t a single inch of her he left untouched. His fingers lingered on her breasts, teasing her nipples until they stiffened under the warm water. He traced the line of her spine, cupped her bottom, and slid between her thighs to stroke her slick, sensitive folds with deliberate slowness.
Lena’s breathing grew ragged, turning into soft, desperate pants as the pleasure built rapidly inside her.
“Please...” she whimpered after long minutes of his unrelenting attention. “Please, Master...”
Elias’s lips brushed her ear, his voice a dark, velvet murmur.
“Mmm ... my love ... my naughty little girl. Do you really think you deserve to come?”
He pressed her back against the cool tile, one hand still between her thighs, circling her swollen clit with slow, torturous precision.
“I think I should keep you desperate for the rest of your life,” he whispered, biting gently at her earlobe. “So beautifully needy. So perfectly mine.”
Lena moaned softly, her body trembling under the water, caught between overwhelming pleasure and the knowledge that her Master was still very much in control — and far from finished with her.
The First Lesson
The warm water continued to fall around them like a gentle rain, but there was nothing gentle about the way Elias held her. He had turned her in his arms, bending her forward over the crook of his elbow, her upper body supported while her legs dangled helplessly. Lena’s heart hammered wildly in her chest as his large palm came down hard on her full soft bare bottom — the first sharp, resounding slap echoing off the tiled walls.
The water made every impact so much worse. The wetness amplified the sting, turning each slap into a deeper, more searing burn that spread across her skin like liquid fire. The moisture prevented the usual cushion of air, making the contact feel raw and unrelenting, as if his hand was branding her with every strike.
Lena sobbed immediately, her body jerking violently with the first blow. “Master—!”
Elias’s grip on her waist tightened, holding her firmly in place. His voice was low, calm, but laced with steel.
“All actions have consequences, my girl. You need to learn this.”
He spanked her again, harder this time, his palm landing with deliberate force on the full curve of her bottom. Lena cried out, legs kicking weakly as the pain bloomed hot and deep. She writhed in his strong hold, trying desperately to escape the stinging blows, but he held her effortlessly, his arm like iron around her middle.
“Why did you go after them, Lena?” he asked, his tone steady even as his hand continued its relentless work. “Why did you put yourself at risk instead of calling me?”
Lena only sobbed harder, unable to form words through the burning pain. Her bottom was already turning a deep pink, the water making each slap feel like fire licking across her skin.
Elias didn’t stop. His palm came down again and again, alternating between her cheeks, the wet slaps loud and merciless. Lena’s cries grew louder, her body twisting and writhing in his arms as the heat spread deeper into her muscles.
“Answer me,” he said firmly, delivering several sharp slaps in quick succession. “Why, Lena? Why didn’t you call me?”
Still no answer — only broken sobs and desperate writhing as the spanking continued, turning her bottom a brighter, more painful red.
The Questions Deepen
Elias’s hand never faltered. He spread her legs wider with his free hand, exposing the sensitive skin of her inner thighs, and brought his palm down hard there too — careful to avoid the healing wound on her outer thigh, but merciless everywhere else. The pain was sharper, more intimate, making Lena scream as the water intensified every stinging blow.
“Answer me Lena. Why did you feel it was necessary to put your life at danger?” he asked again, voice low but firm.
Lena’s sobs turned into full-throated cries, her body jerking and writhing helplessly in his hold. The water made the spanking feel endless, each slap sinking deeper, the burn spreading like wildfire across her skin. Her bottom and inner thighs were a vivid, throbbing red now, every nerve ending screaming.
“Master— please—!” she begged, voice breaking.
But Elias only continued, his palm landing with firm, measured force. “We are going to be here until you start talking little girl.”
She could only sob and writhe, the pain and shame overwhelming her. Her legs kicked weakly, but he held her firmly, spreading them wider when she tried to close them, delivering several hard slaps to the tender inner skin.
The spanking went on for what felt like an eternity — his questions relentless, his hand never stopping. Lena’s cries filled the shower, raw and broken, as the water continued to make every strike feel like pure fire.
The Breaking Point
Elias’s hand came down again and again, the wet slaps loud and merciless. Lena’s bottom was a deep, burning red, the pain sinking into her muscles until she felt like she was on fire. She writhed desperately in his arms, sobbing uncontrollably.
“Why, Lena?” he asked once more, voice steady but edged with steel.
Lena’s sobs grew louder, her body trembling violently. The pain was overwhelming, the shame even more so. She felt so small, so helpless, so utterly owned.
Finally, between broken cries, the truth spilled out.
“I was ... I was afraid ... Samantha would hurt you...”
Elias paused for a brief second, his hand resting on her burning skin. Then he continued the spanking, slower now, but no less firm.
“You thought you could protect me?” he murmured, almost softly. “My brave, foolish little girl. That is not your role. Your role is to obey me. To trust me. To let me protect you.”
He delivered several more hard slaps, making her whimper and tremble.
“You will never put yourself in danger like that again. Do you understand?”
“Yes, Master,” she sobbed, voice raw. “I understand.”
The Paddle
Elias finally stopped, his hand resting gently on her reddened bottom, rubbing slow circles over the heated skin as the water continued to fall around them.
Lena was spent — exhausted, trembling, her skin burning and her breath coming in ragged sobs.
Then she felt him reach out for something.
He brought it in front of her face so she could see it clearly.
It was a wooden paddle — smooth, heavy, and unforgiving.
When it came down, Lena shrieked, the sound raw and broken as the solid impact landed across her already tender bottom. The pain was immediate and devastating, far sharper than his hand, the wet wood connecting with a loud, resounding crack that echoed through the shower.
Elias’s voice remained steady, almost gentle, even as he continued.
“You will learn, my love. You will learn what it means to truly belong to me.”
The paddle came down again and again, harder than his hand, the wet wood making each strike feel like a brand. Lena’s shrieks filled the shower, her body convulsing in his hold as the pain overwhelmed her completely.
The Final Lesson
Elias continued the paddling with steady, deliberate force, turning her bottom a deep, crimson red.
Lena sobbed uncontrollably, her body shaking with every strike, tears streaming down her face.
Finally, when her bottom was a vivid, throbbing crimson, Elias paused.
“The only way anyone can hurt me,” he whispered, voice low and intense, “is through you. So taking care of yourself, letting me protect you, not destroying what I put inside you for protection — that is how you keep me safe. Do you understand now, my love?”
Lena nodded weakly, sobbing. “Yes, Master ... I understand...”
Elias pulled her upright in his arms, holding her close under the warm water, his lips brushing her temple.
“Good girl,” he murmured. “Now you will remember this lesson every time you sit down.”
The shower continued to fall around them, but in that moment, the only thing Lena could focus on was the burning sting of her punishment and the absolute authority in his touch.
She was his.
Completely.
And he had made sure she would never forget it.
Elias cradled her carefully in his strong arms, mindful not to press against her freshly punished, throbbing bottom. He carried her from the bathroom back to the bed, his steps slow and deliberate, as if she were something infinitely delicate that might shatter if handled too roughly.
He lowered her gently onto the soft mattress on her side and drew the silk blankets over her naked body, tucking them around her with quiet tenderness. Then he leaned down and pressed a lingering kiss to her forehead.
“Good night, my beautiful love,” he murmured, his voice rough with exhaustion and lingering emotion. “Go to sleep.”
Lena looked up at him with wide, vulnerable eyes, her voice barely a whisper. “Master ... is it finished? My punishment?”
Elias’s heart constricted painfully in his chest. For a moment, the raw vulnerability in her gaze nearly broke his resolve. But he forced himself to remain firm — for her sake, for both of them. She needed to understand the depth of what she had risked.
“Lena, my love,” he said quietly, sitting on the edge of the bed beside her. “You disobeyed me first by touching your plug. I had told you multiple times you are not allowed to touch what I put inside you. Second, you hurt yourself by cutting your thigh and pulling out what I put there to protect you. Then you sipped a drink you knew was dangerous. And finally, you ran after that crazy woman...”
He paused, his jaw tight, the list weighing heavily between them.
“It’s a very long list, little one. You are exhausted now. We will talk about the proper punishment later.”
Lena’s eyes filled with fresh tears. “I’m sorry, Master ... I really am...”
“Shhh ... I know, my kitten,” he whispered, his fingers beginning to stroke slowly through her hair in soothing, rhythmic motions. “I know.”
Lena hesitated, then asked in a small, hesitant voice, “Master ... what about my butt plug? I left it in that bathroom...”
“I know, my little one,” he replied gently. “We have it. We will talk about that too. Later.”
He continued stroking her hair, his touch the only softness in the heavy silence that followed. Lena closed her eyes, tears slipping down her cheeks, her body still aching from the punishment and her heart heavy with the knowledge that this was far from over.
Elias watched her for a long time, his expression a complex storm of love, anger, and relief. He had almost lost her. And he would make sure it never happened again.
─── The Call
Elias sat alone in his dimly lit office, the weight of the past few days pressing heavily on his shoulders. The estate had been quiet since Lena’s rescue, but the storm inside him had not subsided. He picked up the phone and dialed Alicia’s number, his voice calm but commanding when she answered.
“Alicia, come to my office. We need to talk.”
