Chapter 1
My name is Takumi Nagai. At fifty-eight years old, I am a professor at a well-known university. Throughout my life, I have had numerous opportunities to interact with women. There were encounters at academic conferences and lectures, or relationships with secretaries in my research lab. But every single one of them was merely temporary—nothing more than contact birthed from duty or circumstance. A true "encounter," in the deepest sense, had perhaps remained just out of reach.
It was six months ago that the flames of desire were reignited in my heart.
One day, I was given the results of my annual university health checkup. According to the medical report, my body had deteriorated far more than I had imagined. The decline in my muscle mass was particularly pronounced, prompting a stern warning from the doctor: "If you continue like this, it will start affecting your daily life." Those words dealt a heavy blow to my pride. Knowledgeable though I might be, I was forced to confront the inescapable truth that my physical frame was advancing into old age.
"You ought to start doing some exercise," the doctor advised. Taking the counsel to heart, I decided to join a gym. Yet, given my age, I had no earthly idea where to begin. Desiring expert guidance, I opted to hire a personal trainer.
That was how I met her—Mie Sano.
My very first meeting with her took place in a private room at a high-end gym near the university. As I waited at our appointed time, a tall woman quietly stepped into the room. She was slender and statuesque, her jet-black hair cut into a boyish short style. Her gaze was sharp—possessing an intensity that seemed to grasp the full state of my physical condition in a single glance.
"I'm Mie Sano. I look forward to working with you from today."
Her words were concise, spoken with her emotions thoroughly suppressed. She was remarkably quiet, and her facial expressions were sparse. Yet, that very composure and professional demeanor sparked my curiosity all the more.
"I am Nagai. A pleasure to meet you."
I responded politely, though internally I felt a slight itch to challenge that expressionless mask of hers. Her physique was as toned as a professional model's; with every movement, the beautiful lines of her muscles subtly emerged. Standing before her, I felt a faint flutter in my chest.
Initially, our training sessions proceeded in a matter-of-fact manner. She designed a weight-training regimen for me and taught me proper form. Her instruction was precise, and I applied myself earnestly. Gradually, however, I began to harbor an entirely different kind of interest in her guidance.
Every time her hands touched my body, the sensation of her fingertips burned itself into my mind. Especially during core and back exercises, when her hands reached out to support me, the cool touch of her palms and the faint scent wafting from her body threw my mind into disarray.
"Focus on this muscle right here, Professor Nagai."
When she placed her hand against my waist while saying that, I caught my breath despite myself. The moment her fingers touched my hip bone, a sudden wave of heat surged through my body. She continued her instruction with cool composure, as if feeling nothing at all. But that emotionless attitude served only to fan the flames of my arousal.
A few weeks passed, and as the results of our training began to show, I felt the distance between Mie and me narrow slightly. Quiet as ever, she nevertheless began asking occasional questions about my physical condition and daily habits. To me, it felt as though she was taking a faint interest in me as a person.
One day after a training session, she brought up a topic of her own accord, which was rare for her.
"Professor Nagai, how have you been feeling lately?"
"Ah, thanks to you, much better. I can especially feel my strength coming back."
"I see. I'm glad to hear that."
Saying so, she offered the faintest smile. That smile lit up her usually expressionless face, making her look extraordinarily captivating. In that fleeting second, I felt a powerful pull toward her.
"You're always so earnest, Mie-san," I remarked.
At that, she averted her eyes, looking slightly flustered.
"...It's my job."
"No, I don't just mean that. I think you are simply a very earnest person yourself."
She said nothing, merely lowering her gaze. That reaction drove my fascination with her even further. I wanted to reach deeper into her inner world.
As our training sessions continued, the feelings I harbored for Mie grew increasingly intense. It wasn't merely a physical desire; I was drawn to her mature aura and those fleeting, girl-like expressions she occasionally revealed. Though boyish and mature on the outside, I gradually realized she was deeply modest at heart and quite timid when it came to romance.
After a session one day, I casually invited her out for a bite to eat.
"Thank you for the hard work today, Mie-san. If you're free, would you like to grab a bite nearby?"
An expression of surprise flashed across her face for an instant before her usual composure returned.
"...I'm not sure if I should."
"I certainly don't mean to force you, but if you'd like to."
She pondered for a moment, then gave a small nod.
"All right. Just for a little while."
Internally, I rejoiced at her answer. Her agreeing to spend time with me in private was a monumental step forward.
Over dinner, I posed a question to her.
"Mie-san, how do you feel about things like romance or marriage?"
She seemed somewhat shaken by the sudden question, but quickly regained her composure.
"...I don't really have much interest in romance."
"Is that so? Though I would imagine a woman like you must be quite popular."
"...That's not true at all."
She lowered her gaze as she spoke. In that instant, I sensed something hidden deep within her. She claimed to have no interest in romance, but perhaps she was simply unable to be honest with her own feelings.
"You really are wonderful, Mie-san. I'm quite fond of you."
The words slipped from my lips before I could stop them. Her face flushed red, and she fell silent. Her reaction showed that she felt enough toward me that she couldn't simply dismiss my words out of hand.
"...I, too... about you, Professor..."
She trailed off, leaving the rest unsaid. Yet, her eyes remained fixed on me. In that moment, I knew with absolute certainty that the walls around her heart were beginning to crumble, piece by piece.
That evening, I invited Mie to my apartment. She hesitated briefly, but ultimately accepted my suggestion. My home was a quiet, serene apartment near the university campus.
"Please, come on in."
She entered the room with a somewhat tense expression. I sat her down on the living room sofa, and we talked softly together. She remained as soft-spoken as ever, but I could tell she was opening her heart to me, bit by bit.
Before long, I reached out and took her hand. It felt cold, trembling slightly in my grasp.
"Mie-san, you truly are beautiful."
Saying this, I placed my hand gently against her cheek. She closed her eyes and leaned her face into my palm. In that moment, I longed to touch her lips, but knowing I shouldn't rush, I ran my fingers through her hair first.
"...Professor," she murmured softly.
Her voice was sweet and utterly mesmerizing. Pulling her gently into an embrace, I buried my face against her shoulder. Her body was stiff with tension, but within my arms, it gradually softened.
"Mie, it's alright. I won't hurt you."
"...I know."
She buried her face into my chest as she spoke. I gently stroked her back. Her skin was smooth, and with every touch, I felt a blossoming warmth radiating from within her.
Before long, I gently touched my lips to hers. She widened her eyes in surprise but quickly closed them, accepting my kiss. It started as a light kiss but soon deepened. Her lips were soft and carried a sweet scent. I gently licked her tongue and slid mine into her mouth. Mie seemed a bit flustered at first, but soon she began to respond to my tongue.
"Mmm..."
Her sweet voice heightened my arousal even more. I pressed her body close against mine and reached for her breasts. They were on the smaller side, but beautifully shaped and pleasant to the touch. I gently pinched her nipples and rolled them between my fingertips.
"Ah..."
Mie let out a soft gasp. That reaction prompted me to tease her nipples further. They gradually hardened, responding to my touch. Her body began to heat up, answering my caresses.
"Mie, it's okay to let yourself feel it."
I whispered this into her ear. She nodded and closed her eyes; her expression was so lovely that it set my heart ablaze.
I began to undress Mie. She seemed a little shy but made no move to stop my hands. Her naked body was more beautiful than I had imagined—toned and muscular, yet possessing a feminine softness. Her abs, in particular, were firm; I could feel their solidity when I touched them.
I laid her down on the bed and kissed her lips again. She wrapped her arms around my neck and held me tight. In that moment, I knew for certain that she wanted me.
"Mie, I want you..."
Saying this, I parted her thighs. Her intimate area was already wet; when my fingers touched it, she let out a soft gasp.
"Ah..."
I gently stroked her clit and slid my fingers into her wet, hot vagina, feeling it clench around them. As I moved my fingers, I licked her clitoris with my tongue.
"Hya... no..."
Mie cried out. Her body grew hotter and hotter in response to my caresses. Relishing her reaction, I stimulated her insides even more intensely.
"Do you want to come, Mie?"
"...Nn... I'm coming... I'm going to cum..."
The moment she said that, her body shuddered violently as she reached her climax. Her vagina clamped down hard on my fingers, and I could feel the intense heat. She closed her eyes and let out a deep breath.
"...That was amazing..."
She murmured. I kissed her forehead and held her close.
"Mie, I want you to feel even more."
Saying that, I stripped off my underwear and slid myself inside her. Her vagina, still hot from her recent orgasm, welcomed me snugly. I moved my hips slowly, gauging her reaction.
"Ah... nn..."
Mie began to move her hips in response to mine. Her vagina tightened around me, creating a sensation that felt incredible. I pressed her body against mine and thrust deeper inside her.
"Mie, it feels so good inside you..."
"...Yours is... so big..."
She said, wrapping her arms around my back. That moment sent a surge of excitement through me, and I quickened my pace. Her vagina enveloped me completely, and that tight, gripping sensation drove me toward my own climax.
"Mie... I'm coming..."
"...Me too... I'm coming..."
We reached the peak together. Her vagina contracted violently, moving as if to wring the semen from me. I released everything inside her, filled with a deep sense of satisfaction.
After our passionate encounter, we lay close together in bed. Mie wore a gentle expression as she rested in my arms. It was a moment when her mask of stoicism had completely fallen away, revealing her true self.
"Professor..."
"Hmm?"
"...Can I see you again?"
I smiled at her words.
"Of course. I want to be with you always."
Mie gave a small nod and buried her face against my chest. In that moment, I felt our relationship shift from that of a mere trainer and client into something much deeper.
From that night on, we began seeing each other frequently. Although Mie remained cautious about romance, she seemed to be gradually opening her heart to me. The time I spent with her had become incredibly precious to me.
