No secrets
The luxury car purred smoothly along the scenic road leading away from the estate. Elias was driving himself today, one hand on the wheel, the other occasionally resting on Lena’s soft thigh, stroking up and down occasionally. She sat quietly in the passenger seat, wearing the soft white sundress, staring out at the passing trees.
After several minutes of silence, Elias glanced at her.
“Lena ... I hope you know the pain you felt yesterday was never my intention,” he said, his voice low and serious. “I’m truly sorry. I won’t be that careless with you again.”
Lena turned her head slowly to look at him. Her voice was quiet, almost hollow.
“I thought you liked seeing me in pain.”
Elias’s grip tightened slightly on the steering wheel. He pulled the car over to the side of the quiet road and turned to face her fully.
“No, my love. That is absolutely not true.” His gray eyes held her deep blue eyes with surprising intensity. “There are many things I will have to do to train your body. Some will be painful. Some will test your limits. Some will be hard for you. Pain is part of your discipline. Pain leads to pleasure. Pain shapes us in to something greater. But the agony you felt last night ... that was not what I wanted or intended for you to feel.”
Lena knew he was telling the truth. She didnt recieve any signal from his emotions that he was trying to decieve her. She was feeling ... remembering the familiar colors ... it seemed that he was right. Whatever he was doing to her body was starting to turn on something inside her. Very old and unfamiliar emotions were beginning to stir deep in her mind. It gave her the ability to sense his emotions. Maybe her gift was coming back.
She was getting deeply confused about his intentions. She no longer knew if all he did was for his own pleasure or if he really wanted her to gain her gift back ... or if she even wanted that ability back? Or what was his long term intentions for her? The most terrifying but logical explanation was that he wanted her as a test subject because of her gift. A lab rat. But if it was the case why didnt he take her as a child? Her gift still intact and her mother out of the picture, with no other living relative and he was already her legal gaurdian. He chose to help her mother to gain back her health and then he encouraged her to take care of her daughter. And he even suppressed her gift himself. Lena thought her head was about to explode. The truth was she was very smart but Elias was even smarter than her. She didnt know if she could find out about his true intentions ever.
Elias paused and thought for a moment, his hand casually stroking just her thigh above her knee.
“Sometimes I have to inflict pain as a punishment for you to learn. Sometimes pain will heighten your arousal. Your sensations. Its called erotic pain. For example a spanking causes blood flow to increase in your pelvis, causing more intense pleasure.
Seeing her shocked expression, he added.
“Yes, this is physiologically accurate my love. Spanking causes pain or impact to the gluteal area, this triggers *vasodilation*. — blood vessels in the pelvic region dilate and increase blood flow to genitals which causes heightened sensitivity and arousal. Also releases *endorphins and adrenaline*. The gluteal region shares nerve pathways with pelvic and genital nerves. The *pudendal nerve connects the buttocks and genitals. Pain and pleasure signals travel similar pathways in the brain (somatosensory cortex*).
So yes, there’s a real anatomical and neurological basis for it my love. Also More intense impact equals greater blood flow surge to pelvis and Larger endorphin release — So the more pain inflicted to your bottom you can reach “endorphin higher” similar to runner’s high. Adrenaline spike heightens all sensation.
“So you see my love, pain intensifies arousal.”
“Therefore in that setting I WILL train you to endure pain for me. For your training, for your pleasure and mine. But what you experienced yesterday, it wasnt my intention. Im sorry and if I can go back in time, I will change how it happened. Fortunately its only once. Its done and you wont feel that pain again my sweet.”
“I ... I have a question,” she whispered, her voice small but steady. “I’m sure you could have removed my hymen surgically. So I wouldn’t suffer that much pain. If you could go back in time ... would you do it that way?”
Elias went completely still. For a long moment, the only sound was the wind outside the car. Then he shifted, gently turning her face so he could look into her eyes. His expression was unusually serious — a mix of surprise and something deeper, almost pained.
He brushed a lock of hair from her face with careful fingers, studying her as if searching for the right words.
“I could have,” he admitted quietly. “It would have been simple. A quick, painless procedure under local anesthesia. No blood. No tearing. No shock to your body.”
Lena waited, her breath held.
Elias’s gaze darkened with intensity as he continued.
“But no ... I wouldn’t have done it that way. Even if I could go back.”
He cupped her cheek, his thumb stroking her skin with surprising tenderness.
“Taking your virginity my little love— truly claiming you for the first time — had to be done naturally. With my body inside yours. I needed to feel that moment. The resistance. The breaking. The way you opened for me and only me. That pain ... it was part of the bond. Part of making you mine in the most primal, irreversible way. I wanted you to feel it. I should have been the one who caused it and the one who comforted you through it.”
His voice dropped lower, almost regretful.
“I know it hurt you. And I’m sorry for the pain itself. But I’m not sorry for how it happened. That first time ... it sealed you to me. In blood. In surrender. In memory.”
Lena’s eyes filled with tears. She searched his face, looking for any sign of doubt, but found only absolute conviction.
Elias leaned down and kissed her forehead, then her trembling lips, holding her close as if to shield her from the very truth he had just spoken.
“If I could go back in time I would have given you more sedative. Thats the only thing I could have changed.”
“Not everything in life my love,” he whispered and leaned forward against her mouth, “can be made painless. Not if they are to mean everything.”
Lena closed her eyes, a single tear slipping down her cheek as she listened to the man who had both broken her and claimed her so completely.
Lena looked down at her hands, then asked the question burning inside her.
“Are you going to take me next ... in my back there?”
Elias shook his head immediately.
“No, my sweet. Your anus isn’t designed to take the huge size of my penis. I won’t do that to you. For that part of your anatomy its not just about pain, its more about the harm. The permanant harm. I refuse to damage you. I doubt it can be done safely even with intense training in distant future.” He reached over and brushed a curl behind her ear. “But your whole body including your little anus belongs to me now. I will regularly check you there. I will finger you. I will use plugs and other devices in future. The training you get there, in your lovely little anus, will be complete and thorough. That part is not negotiable. Also the anus has a high concentration of nerve endings, you know these my little flower ... you have studied them, the pudendal nerve and pelvic splanchnic nerves densely innervate the area. Similar nerve density to lips and fingertips. The anal sphincter also — very sensitive to touch and pressure. You will absorb anything I desire, through your mouth or your passy or your anus. Pleasure or pain or nutrients. Anything I see fit goes in to your lovely little body through any path I choose in the exact time or amount I decide and you my little pet, will learn in time to accept and to enjoy that. You will beg me in future. Im certain. Just give yourself time and trust me.”
Lena’s eyes filled with fresh tears. “But Why? Please ... I don’t want this.”
“Lena my love, its not always about what someone wants. Its more about what you NEED. And I know what you need to grow, to become your best version. Because every part of you belongs to me completely, you have belonged to me almost all your life my love. “ he said, his tone calm but absolute. “I will train and use your body as I see fit. It is all for your health, Lena. Look at your skin. Look at how your energy has already improved. That is because of the plug and its delivery system. The rectum has vast capillary networks — the most efficient and gradual absorption route. And eventually together we will bring back your gift someday. You will be able to do wonders then. I suspect that even now you are feeling your old gift coming back. You just wont admit it to me.”
He winked at her playfully, confirming that he knew what was going on inside her head.
“Can’t you just give me the drugs another way?” she pleaded softly.
“We have already talked about this little one. No. I will decide what substance goes in which part of your body. Your mouth, your pussy, your rectum and all of you. “ His answer was gentle but final. “And you need to start accepting something important my doll, you have no secrets from me. No privacy. In the future, I will watch you while you pee. I will monitor every and each function of your body carefully. You must learn to accept that you are completely mine — inside and out.”
Lena turned her face away, staring out the window as silent tears slipped down her cheeks. The beautiful scenery blurred before her eyes.
Elias watched her for a long moment, then reached over and gently wiped a tear from her cheek with his thumb.
“I know this is hard,” he murmured. “But I will take care of you, little pet. Better than anyone else ever could. Trust me again ... even if it’s only a little at a time. If you learn to give up control to me this will go much easier. I just want you to trust me my love. Will you do that?”
“Sir ... how can I ever trust you? I entered your estate just as a surgical resident. You made me sign a contract ... but it was all a beautiful lie. Through that contract, you made me a captive. A slave ... in your estate. You took away my freedom ... my simplest rights as a human being. How can I ever trust you again?”
He cupped her face with both hands, his thumbs brushing away the tears that had begun to fall.
“Lena...” he said, his voice low and rough with emotion. “I never lied to you. Not once. The contract was clear from the beginning — you would live in my estate, under my care, for four years. You would assist me, learn from me, and in return, I would erase your debts and give you the future you deserved. You signed it willingly because you wanted what I offered.”
“Let me remind you of what you agreed to my little lady.”
Lena’s heart sank as he grabbed his tablet and began scrolling through the document in his tablet, highlighting clauses with clinical precision.
“Clause 4.2,” he read aloud. “The Assistant agrees to reside full-time on the Estate grounds for the entire duration of the contract (four years), with no right of unilateral departure without the written consent of Dr. Elias Voss. Any attempt to leave without approval shall result in immediate forfeiture of all financial benefits, including full repayment of student loans with interest.”
He looked at her.
“You signed this. You agreed to live here. You agreed that leaving without my permission would put you back in debt. When you ran away the other day, did you have my written consent?”
Lena’s face paled.
He continued, voice steady.
“Clause 7.1: The Assistant grants Dr. Voss full authority over her daily schedule, medical care, nutrition, physical training, and disciplinary measures as deemed necessary for her professional development and personal well-being. This includes, but is not limited to, corporal correction when verbal instruction proves insufficient.”
Elias met her eyes directly.
“This is the part that legally allows me to punish you, Lena. You gave me the right to discipline you physically if I believe it’s needed for your growth. You didn’t read it carefully. You were too excited about the opportunity.”
Lena’s lips trembled. She remembered skimming the long, dense document in a rush of hope and desperation, eager to escape her debts.
“Clause 9.3,” Elias went on. “The Assistant consents to all medical and physiological interventions recommended by Dr. Voss for the purpose of optimizing her health and performance, including but not limited to monitoring devices, nutritional supplements, and bodily modifications as required.”
He set the tablet down and took her hand.
“You signed away control of your body, Lena. You agreed to let me monitor you, modify you, and use whatever means I see fit to make you the best version of yourself. You didn’t notice because the language was elegant, professional, and buried in pages of legal terms. That’s how contracts work.”
Lena felt sick. The beautiful lie she had signed was now crystal clear.
Elias leaned closer, his voice firm but not unkind.
“You should always pay attention to what you sign, my love. Words have power. Especially when they are written down and signed as a contract.”
He kissed her forehead gently, almost lovingly.
“But it doesn’t matter now. I am just telling you this so you understand that I never lied to you.”
Lena’s voice cracked with raw emotion as she stared up at him, tears shimmering in her eyes.
“But you knew I was naive,” she whispered. “You knew I didn’t understand the full meaning of those clauses. You took advantage of my naïveté.”
Elias was silent for a long moment. He didn’t look away. His intense eyes held hers without flinching.
“Yes,” he said finally, his voice low and honest. “I did.”
Lena’s breath hitched, fresh pain flashing across her face.
Elias reached out and gently cupped her cheek, his thumb brushing away a tear.
“I knew you were innocent. I knew you were desperate to escape your debts and eager for the opportunity I offered. I used that. I crafted the contract in language that sounded generous and professional, knowing you wouldn’t read between the lines. I took advantage of your trust.”
He leaned closer, his forehead resting against hers.
“But my intentions were never to harm you, Lena. Everything I did — the contract, the control, bringing you here — was for your own good. I would have taken you with or without that piece of paper. The contract was simply insurance. A way to make it legal. Certain. So no one could ever take you from me, which no one can anyway.”
Lena trembled in his arms, her voice barely audible.
“You ... you admit it?”
“I admit I didn’t tell you the full truth,” Elias said quietly. “I hid the depth of my plans. I hid how completely I intended to own you. But I never lied to you, my love. Every word in that contract was true. Every promise I made — to clear your debts, to train you, to give you a future beyond what you could imagine — I kept.”
He kissed her forehead, lingering there.
“I know it feels like betrayal. But to me, it was necessary. You were slipping through the cracks of an ordinary world that didn’t deserve you. I couldn’t allow that. So I took you. And I will never be sorry for it.”
Lena closed her eyes, tears slipping down her cheeks as she lay in that car and in the arms of the man who had just confessed to manipulating her ... while still claiming it was all out of love.
The worst part was the terrifying realization slowly settling in her heart:
She was starting to believe him. To accept his words.
After a long silence, she whispered the question that had been burning inside her.
“Are you going to repeat this again in the future?” Her voice cracked. “How can I ever trust you if you hide things from me like this?”
Elias was quiet for a moment. He held her closer, one hand gently stroking her hand as he answered with calm honesty.
“Lena,” he said softly, “you don’t need to know everything.”
She stiffened, but he continued before she could protest.
“Just know that I love you. Deeply. More than I have ever loved anyone or anything in this world. And I would never harm you. Not truly.”
He tilted her chin up so she could see his eyes — dark, intense, and unwavering.
“But beside that ... I can’t promise to tell you everything. There are parts of my life, my work, my estate and my plans for you and myself that you do not need to carry. Some things are mine to bear alone. Trust isn’t about knowing every detail. It’s about believing that whatever I do, I do it because I believe it is best for you. For us.”
Lena’s eyes filled with fresh tears.
“How can I believe that when you’ve already tricked me once?” she whispered.
Elias leaned down and kissed her forehead, lingering there.
“Because I am telling you the truth now,” he said. “I won’t lie to you. I may not tell you everything ... but what I do tell you will always be honest. That is the best I can offer you, my love.”
“There is a some sort of tracking device in me. In my thigh. It has been since the second day. Isn’t it?” She whispered.
He pulled her tighter against his chest, wrapping her in his arms as if to shield her from the very reality he had created.”Yes little girl. I put it there the second day you arrived. Its for your protection.”
“How can I ever trust you when you put a tracker in me without me even knowing?”
“Trust will come with time, Lena. Not because I give you all the answers ... but because you will see, day after day, that I keep you safe. That I cherish you. That everything I do — even the things that hurt or confuse you — come from love.”
Lena closed her eyes, pressing her face into his chest, feeling the steady beat of his heart against her cheek.
She didn’t know if she could ever fully trust him again.
But in that moment, wrapped in his warmth and his unyielding possession, she understood one painful truth:
She had no choice but to try.
