That’s it ... good girl. Swallow for me.”

He cut tender pieces of duck, offered her few sips of the exquisite wine, and made sure she finished every course. The act was deeply erotic—his hard thighs beneath her, the heat of his body surrounding her, the casual dominance of being fed like a cherished pet. His free hand occasionally stroked her thigh or rested possessively over her stomach, feeling her breathe and swallow.

By the time the final course—a delicate dark chocolate mousse with fresh berries—arrived, Lena was flushed, full, and trembling with a confusing mix of submission and arousal. Elias’s arm never loosened its tight hold around her waist.

Only when she had taken the last spoonful did he press a slow, claiming kiss to the side of her throat.

“Now,” he said, voice dark and satisfied, “you’ve been a good girl for your Master. We can talk about your patient.”

Lena shifted on his lap, her stomach pleasantly full from the lavish meal. “Master ... I’m full,” she murmured, turning her head slightly.

Elias’s arm tightened around her waist, pulling her more firmly against his chest. His voice dropped into that low, unyielding register. “You will eat anything I want you to eat, my love. Now be a good girl and open your beautiful lips.”

Lena hesitated only a moment before parting her mouth obediently. Elias fed her the first smooth, intense spoonful, watching with dark satisfaction as she swallowed. “That’s my pet,” he praised softly, his breath warm against her ear. He took a bite for himself, then offered her one more—only two spoonfuls in total—before setting the spoon aside.

He pressed a lingering kiss to her temple, then spoke again, his tone shifting to something more deliberate and probing. “Now, about Your patient. Do you really want to know the donor?”

Lena blinked, confusion clouding her expression as she twisted slightly in his iron grip. “I ... What do you mean, Master?”

Elias regarded her with that calm, penetrating gaze, his hand slowly stroking her side in a possessive rhythm. “It means, my love, you have a choice. You can simply say, ‘Master, I want those legs,’ and they will be in your operating room tomorrow morning—perfectly matched, viable, and ready. Or ... you can insist on knowing exactly where and whom they come from.”

Lena was speechless, her pulse racing. Dark thoughts flickered through her mind—shadowy possibilities that made her stomach tighten despite the luxurious surroundings.

“I ... I need to know, Master,” she whispered at last.

Elias nodded, as if he had expected nothing less. “I thought so. I know you, my angel.” He brushed a strand of hair behind her ear, his touch deceptively gentle. “Those legs belong to a ten-year-old girl in England. She murdered three other children. She’s been sentenced to life in a secure psychiatric institution. We can acquire her for our advanced neurological trial ... and your patient can have her legs.”

He fell silent, watching her reaction with intense, unwavering focus, his arm still locked possessively around her waist.

Lena’s breath caught sharply. Horror and disbelief crashed over her. She stared at him, her voice trembling as the words finally came.

“Master ... she’s only a child. A deeply disturbed child, yes, but still ... How can we—? My patient deserves a chance at a normal life, but not at the cost of harvesting from another living child, no matter what she’s done. I can’t ... I won’t sentence another child to that kind of loss.”

Elias’s expression remained calm, almost regretful, though his arm stayed locked possessively around her waist, holding her firmly on his lap.

“That child will never have a normal life, Lena,” he said quietly, his steel-gray eyes steady on hers. “She will never know freedom, never run through a field, never live outside the walls of a secure mental institution. She is a proven danger to society—I’ve reviewed her interviews myself. The best we could hope for is to make her somewhat more docile through our neural implants ... and even that is uncertain.”

He brushed his thumb across her lower lip, voice low and unyielding. “Sometimes mercy looks different than you expect, my love.”

She searched his face desperately, pressed tight against him, torn between her oath as a doctor and the terrifying reality of the man who held her so completely in his grasp.

“But master ... There has to be another way. Please tell me there’s another way.”She pleaded with her deep blue eyes.

The candlelight flickered across the table as Elias held her securely on his lap, his voice calm and matter-of-fact, yet laced with that quiet dominance she could never escape.

“As you know, my love, a donor for a child should ideally be a child—age-matched, tissue-compatible. The other option you seek is waiting for a deceased donor of similar age ... which, in your patient’s narrow time window, is not very likely.”

He stroked her side slowly, watching every shift in her expression. “Anyway, the final decision is yours, my little surgeon.”

Lena felt torn in a way she had never experienced before. Never in her life had she been this indecisive. A heavy wave of regret washed over her—she wished desperately that she had never asked about the donor. The image of the little girl’s wide, pleading green eyes haunted her mind. But How could she possibly condemn another child to that kind of life-altering loss, no matter what horrors the girl had committed?

It was an impossible situation. Her oath as a doctor, her compassion, and the brutal reality Elias offered all collided inside her chest.

“Master...” she whispered, her voice small and pleading, “can you let me do more research tonight? Please. Just tonight. I want to do everything I can for her.”

Elias looked down into her sorrowful, pleading eyes. For once, he didn’t have the heart to refuse her. His hand came up to cup her cheek, thumb brushing gently across her skin.

“Okay, my love,” he said softly. “But I expect you in bed by one a.m sharp at the latest. Is this clear?”

“Yes, Master,” Lena breathed in relief. She turned in his lap, threw her arms around his neck, and kissed him impulsively on his cheek. In a burst of energy, she slipped from his lap and hurried toward the main libraray.

Elias chuckled deeply, the sound warm and indulgent. “No running, Lena. Slow down,” he called after her, his voice carrying effortless authority even through the amusement.

She slowed obediently at the threshold, glancing back at him with a mixture of gratitude and lingering turmoil, then disappeared down the corridor.

Elias remained seated for a moment longer, a rare, genuine smile curving his lips. His little girl was precious. So adorable. So sweet, so hopeful, even when faced with impossible choices. It made his heart soar in a way nothing else ever had. He would give her this night. Tomorrow ... the decision would still be hers to make—under his guidance, of course.


David arrived home at exactly six o’clock that evening, the front door closing with a firm, decisive click. Throughout the day he had remained in close contact with Alicia—text messages, short calls, and even a video check-in during her lunch break—guiding her schedule with calm authority. He had instructed her to leave the estate kitchens by two and return home.

Yet when he stepped into their cozy residence, the warm lights of the kitchen revealed Alicia still standing at the counter, apron on, hands busy arranging delicate garnishes on several prepared dishes for her upcoming class.

The rich aroma of roasted herbs, seared meats, and fresh pastry filled the air. She was deep in concentration, clearly lost in her passion.

David paused in the doorway for a moment, taking in the sight of his wife—flushed, focused, and pushing past the boundary he had clearly set.

“It’s time to rest, Alicia,” he said, voice steady and deep.

She glanced up, a guilty look flashing across her face. “Please, David ... just a couple more minutes. I need to finish these plated samples for tomorrow’s practical evaluation. It’s a big part of the grade in my advanced techniques course.”

David crossed the kitchen in measured strides, his large frame filling the space. “No, my wife. Come here. We need to eat dinner together, then you’re going to bed.”

“Sleep?” Alicia’s eyes widened in disbelief. “But David, it’s too early for sleep.” She whined.

“I know, baby.” He reached out and gently but firmly took the piping bag from her hands, setting it aside. “But from now on, if you need to be up at six, you sleep by ten. No exceptions. Come here.”

He slid an arm around her waist and began guiding her toward the kitchen table, where he had already set two places with simple but warm dinner—grilled salmon, roasted vegetables, and a fresh salad he had prepared earlier.

“But David—”

“No buts, sweetie.” His tone sharpened with warning. “Unless you want a repeat of what happened this morning. Personally, I enjoyed the view of your bright red bottom over my lap ... but I’d rather not start the evening that way.”

Alicia’s cheeks burned crimson. “No ... no. Please. I’ll eat. Let’s eat.”

David pulled out her chair and waited until she sat, then took his own seat across from her. He knew changing long-standing habits took time and patience. But he loved Alicia more than anything in this world—to the moon and back—and he refused to watch her burn herself out again. Her health, their marriage, her happiness ... these came before everything else.

As they began to eat, he reached across the table and took her hand, his thumb stroking her knuckles.

“Alicia, I appreciate your hard work—both outside the house and inside it. But before money, before salary, before any ambition ... your health and happiness are what matter most to me. I love you, my girl. That’s why I’m doing this. I want what’s best for you, even when it’s hard.”

Alicia poked at her salmon, her voice softening. “I love you too, David. But I can’t just sit at home all day. It’s boring. And I really love culinary work. This program—it’s intense, but it’s the first thing in a long time that makes me feel truly alive. It’s not just a hobby. It’s my passion.”

“I know, Alicia,” he replied, his voice warm yet unyielding. “And I want you to pursue that passion. I’m proud of you for it. But passion needs limits, structure, and balance. You were running yourself into the ground before. No more. Do you understand?”

She nodded slowly. “Yes.”

David’s eyes darkened with quiet authority. He set his fork down. “Yes, what, Alicia?”

She stared at him, caught off guard by the shift in his tone.

“From today onward, you will call me Sir when we’re in private like this. Do you understand?”

Alicia’s eyes grew wide, a fresh wave of submissive heat flushing through her body. The word felt heavy on her tongue, strange and intimate all at once. “But...”

David simply raised an eyebrow, waiting.

“Yes ... Sir,” she whispered at last, the word sending an unexpected shiver down her spine.

“Good girl,” he praised, voice low and approving. “Now finish your dinner. After we eat, I want you in the bedroom. We’re going to have an early night—starting with you showing me how well you can use that pretty mouth again before I put you to sleep.”

Alicia squirmed in her seat, the lingering tenderness from her morning spanking combining with the new rules to create a potent mix of reluctance and reluctant arousal. David watched her with dark satisfaction, already planning exactly how he would reinforce tonight’s lesson.

His wife was going to learn balance—one firm, loving correction at a time. David finished the last bite of his meal. He stood, extending his hand to Alicia with quiet command.

“Come with me, little wife.”

He led her into their bedroom, the soft lighting already dimmed to a warm, intimate glow. Once inside, he guided her to the center of the room and stopped her beneath the gentle overhead pendant light, as if presenting her for his personal inspection.

“Stand still for me,” he ordered softly.

His large hands moved with deliberate slowness, peeling away each piece of her clothing one by one. The estate uniform jacket slipped off her shoulders. Her blouse followed, buttons undone with patient care. He unzipped her skirt and let it pool at her feet, then hooked his fingers into her panties and drew them down her legs, leaving her completely bare before him. He took his time, letting his fingertips trail over her skin, brushing the still-tender curves of her bottom from that morning’s spanking.

Alicia shivered under his gaze, cheeks burning.

From the top drawer of their dresser, David retrieved a flat, elegant black box and opened it. Inside lay his gift: an exquisite, barely-there BDSM-inspired lingerie set in deep midnight black and delicate crimson accents. The bra was a sheer mesh demi-cup that lifted and framed her full breasts while leaving her nipples clearly visible through the fine, see-through fabric. Thin leather straps crossed elegantly over the chest and shoulders, accentuating rather than concealing. The matching thong was little more than a tiny triangle of lace connected by delicate silver chains that sat high on her hips, with a thin leather band that circled her waist like a subtle harness. A matching garter belt with satin straps completed the look, designed to make her feel exposed, claimed, and utterly feminine.

“From now on, Alicia,” David said, his voice low and bossy, “the moment you return home, you will undress completely. You will put on this lingerie for me. In our home, this is what you wear. I will dress you myself when we have guests or when it’s cold, but when we are alone, the lingerie is non-negotiable. Understood?”

Alicia stared at the scandalously sexy set, her face flushing a deep, embarrassed red. “David ... it’s so revealing. I can’t just walk around the house like—”

“No buts, Alicia.” His tone left no room for argument. “Now, let’s help you into it.”

He knelt briefly to slide the thong up her smooth legs, adjusting the thin chains so they framed her hips perfectly. He fastened the garter belt around her waist, then helped her into the sheer bra, his fingers deliberately brushing her sensitive nipples as he settled the cups into place. When she stood before him in the full set, the sight made his cock twitch visibly in his trousers. The lingerie made her look vulnerable, erotic, and completely his.

“Beautiful,” he growled in approval. “That’s my good girl.”

He stepped back and began undressing himself with efficient, confident movements—shirt, pants, and finally his boxers—until he stood naked and already half-hard before her.

“Tonight we have oral class, my love,” he said, voice thick with hunger. “Kneel.”

Alicia’s breath hitched, but the memory of the morning’s discipline was still fresh. She lowered herself gracefully to her knees on the soft carpet, looking up at him with wide, nervous eyes.

David threaded his fingers gently through her hair, guiding her closer until her face was inches from his thickening cock.

“That’s my little girl,” he praised, voice rough with desire. “Start slow. Just appreciate it. Kiss it. Worship it with your lips first. Show me how grateful you are to serve your husband.”

Alicia leaned forward, pressing soft, tentative kisses along the thick shaft. She kissed the head, then the underside, her warm breath teasing him as she worked her way down to his heavy balls and back up again. David groaned softly, his grip tightening slightly in her hair.

“Good girl. Now take it into your mouth ... slowly. Use your tongue. We’ll practice deep throating and proper face-fucking later, but tonight we focus on obedience and technique.”

He watched with dark satisfaction as her soft lips stretched around the head of his cock, her tongue swirling hesitantly at first, then with growing dedication. The sight of his wife on her knees in that sinful new lingerie—chains glinting, breasts barely contained, bottom still faintly marked from his hand—filled him with primal pride.

“Deeper, little wife,” he encouraged, voice bossy yet patient. “Relax your throat for me. That’s it ... such a good girl learning to please her Sir. We have all night to train that pretty mouth until you can take every inch like the obedient cocksucker you’re going to become.”

Alicia whimpered around him, the humiliating yet strangely arousing words sending heat pooling between her thighs as she worked to obey, surrendering once again to her husband’s firm, loving control. David was breathing hard, his cock thick and throbbing deep in Alicia’s mouth, when he suddenly pulled her off with a low growl.

“That’s enough for now.”

Before she could catch her breath, he gathered her in his powerful arms and lifted her effortlessly onto the bed. He laid her on her back in the center of the mattress, spreading her legs wide with his knees. With one rough tug, he slid the delicate crimson thong to the side, exposing her slick, swollen pussy. He didn’t wait. In one smooth, possessive thrust, he buried himself to the hilt inside her tight heat.

Alicia cried out, back arching sharply. She was already crazy with need—wet, aching, and desperate from the long oral worship and the constant throb of submission. Her hands fisted the sheets as she whimpered and panted beneath him.

David braced himself over her, his muscular body dominating hers completely. He began to fuck her with deep, powerful thrusts—slow at first, then building into a steady, relentless rhythm. At the same time, both of his large hands cupped her breasts through the sheer mesh bra, thumbs circling and pinching her hardened nipples, tugging at the delicate fabric until she was sobbing with desire.

“That’s it, little wife,” he groaned, voice rough and dominant. “Take every inch of your husband’s cock. This pussy belongs to me now.”

Alicia knew she was in for a long night. David had always been capable of lasting an almost punishing amount of time, especially when he wanted to remind her who was in charge. He fucked her like he owned her—deep, steady strokes that ground against her cervix with every thrust, stretching and filling her completely. The lingerie straps dug into her skin, the chains jingling softly with each powerful movement of his hips.

Minutes stretched into many more. Ten minutes passed, then twenty. Alicia’s whimpers turned into broken moans and desperate cries. Her inner walls were growing sore and sensitive from the relentless pounding, but David showed no sign of stopping. He kept one hand on her breast, rolling and tugging her nipple, while the other slid down to rub firm circles over her swollen clit.

“Please ... Sir...” she gasped, tears of overwhelming pleasure leaking from the corners of her eyes. “It’s so much...”

“You can take it,” he growled, never slowing his pace. “You’ll take everything I give you tonight.”
