Chapter 1
Here is the English translation:
"...I am so deeply sorry... Professor."
Breaking the heavy silence was the feeble voice of Satomi Sayama—my former student, now working as an assistant in my university laboratory.
Dressed in a brand-new suit, she sat directly in front of me with her head bowed, her hands tightly clenched on her lap. She looked for all the world like a child awaiting judgment for her crimes.
The sunlight of late afternoon filtered through the window, but the lab was deathly quiet. The students had long since gone home, leaving only the occasional sound of distant footsteps echoing down the hallway.
Leaning back deeply into the chair opposite her, my eyes remained fixed on the documents in my hands as I finally spoke.
"Satomi, this isn't a simple mistake. A fundamental calculation error was found in the dataset you were in charge of—the dataset for our next academic conference. If this gets out, it could destroy my entire career. Do you understand that?"
My voice was low, yet bone-chillingly cold. The mask of the gentle, mild-mannered professor I usually wore for my students had completely slipped away.
"Y-yes..."
Her voice trembled. She had always been an exceptional student—meticulous, hardworking, and executing my every instruction to perfection. For her to make such an unbelievably elementary blunder was unfathomable.
"Give me a reason."
I looked up from the papers and stared straight into her eyes. She tried to meet my gaze for a split second, but immediately looked away, her cheeks flushing red with a mixture of shame and fear.
"...The truth is..."
She squeezed out the words as if forcing them past a tight throat.
"...My boyfriend and I broke up last week... and I just couldn't bring myself to concentrate..."
Boyfriend. Hearing that word, I clicked my tongue in my mind. I had never heard anything about her having a boyfriend. I had always valued her professional attitude—the fact that she never brought her private life into the workplace.
"And so, you let your work slide?"
"Yes... I am so sorry. To betray your trust like this, I really..."
She hung her head even lower, her shoulders beginning to quiver softly. She looked utterly helpless—and yet, in a way, inexplicably sensual. Beneath her suit jacket, the crisp white blouse heaved slightly with her trembling breaths.
I slowly stood up and walked over to stand beside her. Then, I placed a hand on her shoulder.
"Satomi."
Her body jumped at the touch. Through my palm, I could feel her warmth and the fine structure of her slender shoulder blade.
"Professor..." she murmured softly, her face still turned downward.
"You are talented. Which makes this all the more disappointing. But everyone makes mistakes. What matters is how you take responsibility for them."
I tightened my grip, turning her body to face me. Without resistance, she repositioned herself like a lifeless doll sitting before me.
"Responsibility...?"
She finally lifted her head. Her large eyes were glistening with tears, trembling with anxiety. At twenty-seven, she possessed a dangerous allure—a intoxicating blend of innocent vulnerability and mature, womanly charm.
"That's right. Do you intend to settle a mistake like this with a mere apology?"
I leaned down slowly, bringing my face close to hers. Her breath, faintly warm, brushed against my skin.
"N-no... Of course not..."
"Then what will you do? How do you intend to regain my trust?"
My question had clearly crossed the boundary of professional conduct. Instinctively, she seemed to realize it too. Her eyes wavered even more violently, her cheeks burning crimson.
"I'll... I'll do anything I can... Anything..."
Her voice was faint and raspy, barely above a whisper. In that moment, like a predator closing in on its prey, I stole her lips.
"Nnh...!"
Her small gasp dissolved into the silence of the research lab. I devoured her soft lips ravenously. Offering no resistance, her lips felt terrifyingly defenseless, as if experiencing a man's touch for the very first time.
After a long moment, I released her. Out of breath, she looked up at me through tear-filled eyes. Her expression was a voluptuous mix of terror and sweet anticipation.
"Professor..."
"Satomi... do you truly understand what you're saying?" I asked in a low voice right against her ear. My hot breath sent another shudder through her body.
"I understand... I will take responsibility... with everything I am."
As if resolving herself, she reached out and took hold of my tie. Though her fingers trembled slightly, her action betrayed a clear, firm intent.
"Very well. Then come to my house tonight."
I took her hand and gently brushed my lips against her fingertips. They were cold, yet impossibly supple.
"...Understood."
Though her face was bright red, her response was unmistakable. And in that brief instant, I didn't miss the flare of burning passion that ignited deep within her eyes.
That night, I was sitting in my living room at home, swirling a glass of whiskey. Outside the window, the city's night lights glittered in the dark.
When the doorbell rang, I stood up unhurriedly. Opening the door, I found Satomi Sayama standing there—looking completely transformed from earlier, stripped of all her modesty.
Having discarded her daytime suit, she wore nothing but a pure white long coat. It was glaringly obvious that she had nothing on underneath. Her makeup was light, and her damp black hair spilled over her shoulders. She looked like a seductive siren, far removed from the honor-student secretary of the afternoon.
"...Sorry to keep you waiting, Professor," she said in a fragile, yet unmistakably seductive voice.
"You're late, Satomi."
I invited her inside and closed the door behind her. Timidly, she stepped into the living room.
"Um... what should I...?"
She stopped in the middle of the room, asking with her head slightly lowered. She looked like a helpless lamb brought to the slaughterhouse.
"First, take off that coat," I ordered, sitting back down on the sofa.
She hesitated for a brief moment before nodding silently. Slowly, her hands moved to the buttons of the coat. One by one, they were undone, until the coat finally slid down her body and pooled onto the floor.
What was revealed was her completely defenseless, naked body in its natural state. Her skin was as smooth and fair as moonlight. Her breasts were full, yet firm and uplifted. Her waist curved elegantly, leading down to the hidden place lightly dusted with dark hair.
Overcome with shame, she tried to cover her chest and lower body with her arms.
"Don't hide yourself. Let me see you clearly."
At my command, her trembling hands slowly fell to her sides. Naked, her beauty surpassed my highest expectations. Though it was the mature body of a twenty-seven-year-old woman, it exuded a touching, almost innocent seductiveness.
"...You're beautiful, Satomi."
I took my time scanning her from top to bottom. Feeling the weight of my gaze, her skin gradually flushed a deep, rosy pink.
"Thank you..." she murmured, dropping her eyes in embarrassment.
"Come here."
I beckoned to her. Hesitantly, she walked over to stand before me. Reaching out, I wrapped my arms around her waist and pulled her onto my lap. Her warm, soft skin pressed against my body.
"Ah..."
She let out a small gasp. I wrapped my arms around her back and held her tightly. Then I whispered in her ear,
"Satomi, your body is mine. Understand?"
"Yes..."
She buried her face in my chest and nodded slightly. Her voice was already melting with pleasure.
I reached out and touched her breasts. Their soft, resilient feel made me begin to play with her nipples with my fingertips.
"Ah..."
She let out a sweet moan. Her nipples quickly hardened in my hands.
"Satomi, you're feeling it, aren't you?"
I asked, pinching her nipples.
"Yes... I'm feeling it... Your hands, Professor..."
She answered, gasping. Her body was already writhing and moving in the palm of my hand, seeking pleasure. I laid her down on the sofa and traced my lips across her body. From her neck, down her collarbone, and to her hard, erect nipples. I took one of her nipples into my mouth and rolled it around with my tongue.
"Ah! Not there...!"
She arched her back and let out a shriek. Enjoying her reaction, I continued to tease her nipples.
"Satomi, this part of you is so beautiful. It looks like it would taste sweet."
I lifted my lips from her nipple and whispered in her ear. Her ears turned red, and she shook her head.
"No... I'm embarrassed..."
"There's no need to be embarrassed. I'll savor every part of you."
I slid my hand up her thigh and reached my fingers to her deepest, most sensitive spot. It was already overflowing with nectar, twitching and begging for my fingers.
"Ah! Oh!"
The moment my fingers touched her secret cleft, her body jumped violently. I slowly began to stroke her clitoris with my fingers, now wet with her love juice.
"Ah! No, stop! Don't touch there...!"
She covered her mouth with both hands, but her voice was filled with uncontrollable pleasure. Her body rippled violently in time with the movement of my fingers.
"Why not? This feels good, doesn't it?"
I whispered like a devil in her ear, quickening the movement of my fingers.
"Ah! Yes, but...! No, I'm going to come...!"
Her moans grew louder and louder. Love juice gushed uncontrollably from her secret place, staining my hands and the sofa.
"It's okay, Satomi. Let it all out. Show me everything you've got."
My words gave her the final push.
"Ahhh! I'm coming! I'm coming!"
She arched her body like a bow, reaching a powerful climax. Her face was contorted with pleasure and shame, yet it was terribly lewd and beautiful.
I waited for her climax to subside, then slowly withdrew my fingers. Then, in front of her eyes, I slowly licked the love juice clinging to my fingers.
"Satomi, you're so sweet."
She gazed at my actions, her face bright red, still basking in the afterglow of her climax. Her eyes were no longer filled with fear, but with the intoxicating color of pleasure.
"Professor... give me more..."
She whispered, her breath fading. Those words were a clear expression of desire.
"You want more?"
I lifted her body and kissed her lips again. She actively welcomed my tongue, and we exchanged saliva.
"Yes... I want more of yours..."
She pulled away from my lips, wrapped her arms around my neck, and said clingingly. She looked nothing like the intelligent secretary I'd seen during the day; she was a hungry female.
"I understand. Then I'll give you all of me."
I picked her up and headed to the bedroom. I laid her naked body on the bed. She seemed to be pounding with anticipation.
I quickly stripped off my own clothes, finally becoming completely naked. Then I slid my body between her legs. Her secret place was still twitching, eagerly awaiting mine.
"Satomi, I'm going in."
I embraced her waist and pressed my hard erection against her entrance.
"Yes... please put it in... Professor, put yours inside me..."
She gripped the sheets with both hands, closed her eyes, and said.
I slowly moved my hips forward. Her hot, tight vagina enveloped my member tightly and welcomingly.
"Ahhh...! It's... so thick..."
She cried out, a mixture of pain and pleasure. Enjoying the sensation inside her vagina, I slowly buried myself completely within her body, all the way to the base.
"Satomi, you're so hot inside... so tight, and it feels amazing..."
I whispered my delight into her ear. She responded to my words, clenching her vagina even tighter.
"Ahhh! Don't say that...! I'm going to come again..."
She shook her head, whimpering. But her vagina gripped me even tighter, refusing to let me escape.
I gripped her hips firmly and slowly began to thrust. Her vagina wriggled in time with my movements, giving me an incredible wave of pleasure.
"Ah! Ah! Oh! It's so deep...! All the way to the back of my stomach...!"
Her moans echoed through the bedroom. Her breasts swayed with my movements. I reached out to her swaying breasts, pinching her nipples, and quickened the pace of my hips.
"Satomi! You're amazing inside! Feel it more! Scream more!"
I devoured her body like a beast. She, too, wrapped her legs around my waist and moved her hips herself, seeking deeper pleasure.
"Oh! Yes! It feels so good! Your penis feels so good, Professor! Do it harder!"
She had forgotten all shame and was screaming with desire. The sight was terribly lewd, and yet beautiful.
I tightened my grip on her waist and began my final assault. Her vagina swelled to its limit, gripping my member tightly.
"Satomi! I'm about to come too! Let's go together!"
"Yes! Let's go together! Ahh! I'm coming! I'm coming!"
At the same time as her scream, I released myself completely deep inside her vagina. Her vagina twitched and convulsed, clenching tightly as if trying to squeeze out every last drop of my semen.
"Ahh..."
I collapsed onto her body and let out a deep, deep sigh of satisfaction. She, too, was breathing heavily in my arms.
For a while, we simply felt each other's body heat and heartbeats. Then, as I stroked her sweat-soaked hair, I whispered,
"Satomi, I've taken responsibility now."
She slowly raised her head and looked at me. Her eyes were filled with pleasure, and somehow, with satisfaction.
"Yes... But, Professor..."
She placed her hand on my chest and traced my skin with her supple fingers.
"My responsibilities will continue. I will take care of everything about you, Professor."
Those words were no longer those of an assistant, but a passionate vow from a woman.
Her words, and the fire in her eyes, made me feel a warmth rising deep within me once again.
"I see. Then, I expect you to continue fulfilling your responsibilities."
I pressed my lips against hers, foreshadowing the start of another long night.
Contrary to the cold air of the laboratory, my bedroom was terribly warm with the heat of our bodies. Her hidden passion was a beautiful, yet dangerous, flame I had never known. And I willingly threw myself into that flame.
The next morning, when I awoke, she was still sleeping soundly in my arms. Her defenseless sleeping face was like that of an angel, but the memory of her lewd behavior last night brought a chuckle to my face.
I took a lock of her hair and gently touched her lips.
"Good morning, Satomi."
She slowly woke at the sound of my voice. She looked at me and smiled shyly, yet happily.
"Good morning... Professor."
The awe she had felt yesterday was gone, replaced by a sweet tone.
We were no longer professor and assistant. We were simply a man and a woman, yearning for each other's bodies. Her "wet uniform" was no longer necessary. She would always choose to be naked in front of me.
I embraced her soft body and kissed her lips once more.
The morning light was beginning to gently illuminate our naked bodies.
