By nine o’clock, the worst of the pain had receded into a dull, manageable ache. The medicine Elias had given her, combined with the soothing design of his custom tampon, had worked its quiet magic. Lena rose from the bed feeling steadier, though the dual fullness inside her — the plug and the tampon — still made every movement a private, intimate reminder of his ownership.

She dressed carefully in the surgical scrubs Elias had left for her. For the first time since days, he had allowed her to wear soft, seamless panties beneath the scrubs — a small but significant mercy reserved only for the duration of her menstruation. Once it ended, she knew the rule would return: no panties ever again. No bra, either. Only the thin fabric of her scrubs between her body and his gaze.

She made her way through the connecting corridors to the operating wing, each step shifting the plug and tampon inside her in a way that kept her cheeks faintly warm.

Elias was already scrubbed in, waiting for her at the entrance to the main theater. When he saw her, his gray eyes softened with quiet approval.

“You look better, my love,” he murmured, brushing a stray curl behind her ear. “Come. Stand beside me today. I want you close.”

The surgeries unfolded with the same breathtaking precision Lena had come to expect from him. In the operating room, Elias Voss was nothing short of a god among mortals. His hands — the very same hands that had spanked her, plugged her, claimed her, and tended to her most private places with such possessive care — moved with divine elegance. Every incision was flawless, every suture a work of art. He performed miracles with calm authority.

And yet, between cases, he remained devoted to her. During the brief breaks, he took her to the private rest room attached to the surgical suite. There, away from prying eyes, he fed her himself — small, nourishing bites of fruit, protein, and the special supplements he had designed for her. His fingers would brush her lips as he offered her water or a piece of perfectly seasoned chicken, his gaze never leaving her face.

“You are doing beautifully today,” he told her between the second and third procedures. “Soon I can leave you alone on some cases.”

Lena’s eyes sparkled. She wanted nothing more than to be able to do the surgeris alone.

Lena watched him work and felt something shift inside her heart. He was a contradiction she could no longer fight against. The same man who had reduced her to tears and humiliating surrender was also the brilliant surgeon who guided her with patience and care, the teacher who praised her improving skill with instruments, the protector who fed her with his own hands.

By late morning, a quiet decision crystallized within her.

She would stop fighting him. At least for now.

He held every card. Every piece of power. Every lever. Resistance had only brought her pain and exhaustion. If she wanted any chance of understanding this world — of finding information, of surviving with her mind intact — she would have to submit. Observe. Learn. Wait.

The decision brought a strange, hollow peace.

At noon, after the morning’s cases were complete, Elias took her hand and led her to a smaller procedure room adjacent to the main theaters. The room was softly lit, clinical yet intimate. In the center stood a modified gynecological chair — elegant, padded, with stirrups that kept the legs only slightly apart rather than fully spread. The backrest was inclined at a gentle angle.

“Take off your pants and lie down for me, Lena,” he said calmly.

She had made her decision. She would not fight. Still, her hands trembled as she obeyed, sliding the scrub pants down her legs and stepping out of them. She climbed onto the chair, heart pounding, and lay back. Elias gently guided her feet into the stirrups, positioning her legs in a modest, slightly open stance. The angle tilted her hips upward just enough.

He stood between her parted thighs, his expression focused and professional. With careful fingers, he reached between her folds and removed the used tampon in one smooth, easy motion. It came out cleanly. Lena exhaled shakily, relieved it had been painless.

But then Elias did something that made the humiliation burn hotter than fire.

He held the tampon up to the light, studying it with intense concentration. He turned it slowly, examining the color of the blood, the texture, the saturation. For a long, mortifying minute, he analyzed it in silence before speaking in his calm, clinical voice.

“Menstrual blood can tell us a great deal about your health, little one,” he explained, almost conversationally. “The shade, the consistency, the presence of small clots ... all of it gives me important data. Yours looks healthy today. Good flow. No excessive clotting. The supplements secreted by the plug are already beginning to balance you.”

Lena lay there, legs in the stirrups, face burning a deep, humiliated shade of red. She wanted to disappear.

Elias set the used tampon aside and allowed her to go to the bathroom to relieve herself. When she returned, he had a fresh, clean insert ready. He parted her folds again with gentle fingers and inserted the new one with the same slow, careful precision. It seated perfectly, warm and plush, cradling her with that strange, almost kind efficiency.

As the fresh tampon settled into place, Lena let out a soft, involuntary sigh. It felt heavenly inside her—impossibly soft, like a warm, plush cushion of velvet that molded perfectly to her contours, cradling her most intimate places with a gentle, insistent pressure. Almost immediately, she felt it begin to secrete a subtle, soothing warm liquid that spread through her in slow, luxurious waves. It wasn’t uncomfortable or intrusive; if anything, it made everything feel slicker, more alive, exquisitely sensitive. She only knew it felt divine—a deep, melting comfort that eased every lingering ache and left her tingling with unexpected pleasure. It was pure magic.

She shifted her hips experimentally, eyes half-lidded, before glancing up at Elias with a mix of curiosity and haze. “Master? ... what is this? It feels ... incredible. Like it’s doing something more than just ... absorbing.”

He smiled down at her, his fingers still lingering at her entrance for a moment longer, stroking the soft outer lips with tender affection before withdrawing. “It’s not a regular tampon, my sweet Lena. I designed this one myself. The core is infused with a custom blend—medical-grade, body-safe materials that release a gentle, warming lubricant laced with targeted supplements. Right now, it’s slowly secreting a nutrient-rich solution: electrolytes, soothing anti-inflammatories, and a potent prebiotic formula to balance and nurture your delicate flora. It’s cleaning you from the inside, too—gently breaking down and absorbing any residue while promoting healthy pH and tissue repair. No irritation. No waste. Just constant, thoughtful care.”

Lena’s eyes grew wide, her breath catching as the implications sank in. The warm liquid continued its subtle work, pulsing faintly with her heartbeat, sending little ripples of exquisite sensation through her core.

“You’re ... giving me supplements through a tampon?” she whispered, half in disbelief, half in awe. “Cleaning me ... feeding me prebiotics...?”

Elias nodded, brushing a strand of hair from her flushed cheek. “I thought of everything. Your body deserves precision. This one will last longer, feel better, and keep you perfectly maintained. Comfort, health, pleasure—all in one soft little package.” He leaned in closer, voice dropping to a intimate murmur. “Doesn’t it feel good little one, knowing that your master is taking such complete care of you?”

She could only nod, cheeks burning, as another wave of that heavenly warmth bloomed deep inside her.

When it was done, he helped her sit up and cupped her flushed face in both hands.

“This should become natural for you in time, my love,” he said softly. “All good men should care for their girls this thoroughly. There is no shame in letting me tend to every part of you. I will always do it with care. From now on you will never be miserable during your period my angel.”

“Now what do you say to your master pet?” He asked as he raised her chin, staring in to her deep blue eyes.

“Thank you master?” She whispered.

“No. You will learn to do it properly. This is the proper sentence. ‘Thank you for taking the time to take such good care of me Master.”

As Lena repeated the sentence Elias nodded his head satisfied. He kissed her forehead lovingly.

Lena was still burning with embarrassment, as he helped her back into her scrub pants.

She had chosen submission.

But the weight of it was heavier than she had imagined.

And Elias ... he carried it as though it were the most natural thing in the world.

The final surgery for the day, concluded just after three o’clock. Elias stepped back from the table with the same flawless composure he always carried, removing his gloves as the team began closing. He looked across at Lena, who had assisted with quiet precision throughout the long morning, and his eyes warmed with quiet approval.

“You performed excellently today, My love” he said, voice low enough for only her to hear.

As they left the operating wing, he placed a gentle hand at the small of her back.

“No studying this afternoon for you,” he told her. “No research. No notes. I want you to have a peaceful few hours, my love. You’ve earned it.”

Lena looked up at him in quiet surprise, but she did not argue. She was learning when to simply accept what he offered.

He led her to a private glass elevator tucked away in the eastern tower of the estate. The car rose smoothly, silently, offering a breathtaking view of the vast grounds as they ascended. When the doors opened, Lena stepped into a world that felt almost dreamlike.

The rooftop sanctuary was pure fantasy.

A lush, elevated garden stretched beneath a retractable glass dome that currently stood open to the sky. Flowering vines climbed elegant trellises, and clusters of white roses and lavender filled the air with sweet perfume. In one corner, a private café for senior estate staff offered delicate pastries and fragrant teas beneath a canopy of flowering wisteria. Soft music drifted through hidden speakers — a gentle piano melody that blended with the whisper of wind through the leaves.

Elias guided Lena there with a possessive hand at the small of her back, his touch a quiet reminder of the intimate morning ritual they had shared only hours earlier. As they approached the café, every member of the estate staff who caught sight of him brightened instantly. One after another, they greeted him with genuine warmth.

“Good morning, Dr. Voss,” called the head gardener, pausing mid-conversation with a radiant smile. “The new hybrid roses you suggested are blooming beautifully, sir. We can’t thank you enough.”

A senior housekeeper approached next, her eyes lighting up with unmistakable affection. “Sir! The staff lounge renovations are complete—exactly as you envisioned. You always know just what we need.” She chatted happily for a moment about her daughter’s recent university acceptance, which Elias had apparently supported, before excusing herself with a respectful nod and a lingering, grateful glance.

Others followed in turn—chefs, maintenance leads, administrative aides—all pausing their duties to offer cheerful hellos, share small updates, or simply express how pleased they were to see him. Their voices carried real fondness, a mix of deep loyalty and personal warmth, as though each one owed him a profound debt or simply adored the man who led them. Elias responded to every greeting with effortless charm: a kind word, a thoughtful question about their families, a low laugh that seemed to put them at ease. He was magnetic here—approachable, generous, almost paternal in his care for those who served the estate.

Elias guided Lena with gentle poise through the fragrant café, his hand still resting lightly at the small of her back — a touch that, to any observer, spoke only of protective affection. The afternoon light filtered through the open glass dome, casting a golden halo over the scene as staff members continued to drift toward him with smiles and warm greetings. Rather than brushing past them, Elias paused deliberately at the heart of the gathering, drawing Lena forward with unmistakable pride.

“Everyone,” he said, his voice carrying that rich, charismatic warmth that seemed to put the entire room at ease, “I’d like you all to meet Lena Monroe.”

He turned to her with a soft, respectful smile, his eyes meeting hers with public tenderness. “Lena is my partner and my resident, and she will be spending more time here at the estate. I trust you will all make her feel as welcome as you have always made me.”

The introduction was delivered with utmost courtesy — no casual dismissal, no possessive claim that might hint at the deeper dynamics between them. He spoke of her as an equal, a cherished presence in his life.

“Dr. Lena,” the head gardener said warmly, extending a hand, “it’s an honor. Dr. Voss has mentioned how brilliant you are. We’re thrilled to have you here.”

The senior housekeeper beamed, clasping Lena’s hand gently. “We’ve heard such lovely things. If you need anything at all — anything — please don’t hesitate. Dr. Voss takes such good care of all of us; we’re happy to extend that same care to you.”

Elias stood beside her throughout, nodding approvingly, adding small, respectful details about Lena’s medical background and interests that made her sound accomplished and valued rather than merely his possession. He listened attentively when staff addressed her directly, never interrupting, never overshadowing. To the outside world, he was the perfect gentleman — attentive, proud, and deeply respectful.
