Chapter 1

That was the day I bumped into her just as I was leaving the lecture hall.
The campus was wrapped in the pleasant warmth of spring, bustling with the youthful smiles of new students. Though I’ve taught at this university since I was a young man, this annual scene never fails to lift my spirits. That day, however, there was one person in particular who caught my eye.
A woman was standing in the lobby of the lecture building. Tall and slender in a sharp black suit, she carried an aura that set her completely apart from the students around her. Her black hair, pulled back into a ponytail, accentuated the line of her neck, and her long legs extending from beneath her skirt naturally drew the eyes of anyone passing by.
"Are you looking for something?" I called out, glancing at the documents she held in her hands.
"Ah... no. I'm just a little lost..." she answered slowly but clearly. Her voice had a low, calm cadence to it. "I have some documents to submit to the office here at the university..."
When I accepted her business card, I saw the name "Shiho Nakanishi." She was nineteen years old and worked as a receptionist for a major corporation.
"Ah, the main office is on the third floor of this building. The elevators are right over there."
Looking in the direction I pointed, she smiled and offered her thanks. In stark contrast to her otherwise serious demeanor, that smile carried a touch of quiet allure.
"Thank you very much. That was a big help."
She gave a polite bow and made her way toward the elevators. Watching her walk away, my eyes were instinctively drawn to the gentle curves of her hips beneath her skirt.
Though I am fifty-eight years old, my interest in women hasn't faded in the slightest. If anything, I pride myself on believing that the experience I've gathered over the years allows me to appreciate a woman's charm far more deeply than I did when I was young. While I am known as a respectable professor at the university, I maintain relationships with several women in my private life. Naturally, none of them know me beyond what I choose to show, nor do they know about one another. That is my rule.
However, Shiho Nakanishi was distinctly different from the women I had known before. The aura she carried wasn't merely the appeal of youth; there was something hidden beneath the surface, something that stirred my intellectual curiosity.
From that day on, she occupied my thoughts. I found myself waiting near the main office on the off-chance she might appear, or wandering around spots where she might be between lectures.
Eventually, the opportunity to speak with her again arrived. This time, it was at a cafe near the university, where she was sitting alone, sipping a cup of coffee.
"Nakanishi-san, are you by yourself?"
A flicker of surprise crossed her face when she saw me, but it quickly melted into a smile.
"Professor Nagai... Yes, just taking a quick break from work."
"How nice. Mind if I join you for a cup?"
She nodded, and I took the seat across from her.
"Did you have business at the university today?"
"Yes, just submitting some documents like the other day. I'm still a newcomer at the company, so I spend a lot of time following my seniors around."
She spoke leisurely as she brought the coffee cup to her lips. Even that simple gesture seemed subtly laced with charm.
"So you didn't graduate from this university yourself, then?"
"No, I didn't. But I really like the atmosphere here. It feels good to absorb the energy of all these young people."
She narrowed her eyes softly as she spoke. It was then that I noticed her gaze fixed straight on me—it wasn't just mere polite respect, but a look loaded with something else entirely.
"Have you been at this university since your own student days, Professor?"
"Yes, it's been over thirty years now. Back when I was young, I used to run around this campus just like those students out there."
I offered a somewhat self-deprecating laugh. She let out a soft chuckle and replied, "I can't quite imagine that."
"You look very young to me, Professor."
At those words, I smirked on the inside. Knowing how to say what a woman wants to hear is one of my specialties.
"Thank you. Though I'm almost at my sixties, so to young people like you, I'm probably just an old man."
"Not at all. I actually prefer older men."
The sudden statement sent my heart racing. This wasn't just casual chatter—it was a clear, unmistakable sign.
"Is that so? And why is that?" I asked, deliberately keeping my tone composed.
A faint blush touched her cheeks as she took her time to answer.
"Older men are calm, and they seem to know everything about the world... I find that very dependable."
"I see. But older men have their fair share of issues too, you know—energy, sensibilities, and the like."
I posed it as a slight provocation. Her eyes widened just a fraction before another soft laugh escaped her lips.
"I like all of that included. You must be very experienced in those matters, aren't you, Professor?"
Her eyes swept slowly up and down my body, carrying a clear, unmistakable desire.
"You are quite bold, aren't you?"
"When it comes to things I like, I just prefer to be honest."
Saying so, she set her coffee cup down and stood up.
"I should get back to work soon. Thank you very much, Professor."
She bowed politely and stepped out of the cafe. Watching her walk away, I felt a surge of quiet triumph inside. This woman was definitely targeting me—and I had already decided that she would be mine.
After that day, we began exchanging messages. On her days off, she would drop by my research office, and occasionally, I invited her over to my apartment. She showed an unwavering affection for me, yet at the same time, she played the game masterfully. She didn't rush into bed, deliberately maintaining a tantalizing distance that only stoked my desire to conquer her.
And then, that day finally came. It was a Friday night when she came to my apartment.
"Professor, do you have time to relax tonight?" she asked the moment I opened the door, her expression a mix of anticipation and nerves.
"Ah, yes. Tomorrow is my day off, so take your time."
I ushered her into the living room and poured two glasses of wine. She sat on the sofa and slipped off her suit jacket, her white blouse clinging softly to the slender lines of her figure underneath.
"Professor... I like you."
Holding her wine glass in one hand, she looked straight at me. Her eyes were glistening, heavy with desire.
"I like you too, Shiho."
I sat down beside her and took her hand. It was slightly damp, revealing her underlying nervousness.
"However, I am married, and you are still young. This relationship might not be good for you."
I said it deliberately to test her. She shook her head, her voice firm.
"I don't care about any of that. I only want to treasure the time I spend with you, Professor. I don't want to think about anything else."
Her answer satisfied me completely. She understood that this arrangement was temporary, and that was the most important thing for both of us.
"Shiho..."
I breathed her name and stole her lips. Her eyes widened briefly in surprise, but she quickly closed them and yielded to me, her lips soft and tasting sweetly of wine.
We kissed, devouring each other's lips. Her tongue slipped into my mouth and entwined with mine; the sensation sent my arousal soaring.
"Shiho, come closer."
I pulled her waist toward me and sat her on my lap. She complied hesitantly. As she did, her skirt rode up, revealing her thighs. I instinctively reached out to touch that smooth, pale skin.
"Ah..."
She let out a soft gasp. I stroked up along her thigh and slid my hand beneath her skirt, touching her most intimate place. It was already wet and warm, welcoming my fingers.
"Shiho, you're already so wet."
"Well... because you're touching me, Professor..."
She spoke shyly, yet her body moved as if craving my touch.
I undid the buttons of her blouse and shifted her bra aside, baring her breasts. They weren't large, but they were beautifully shaped. Her nipples had already hardened; when I pinched them with my fingertips, she let out a sweet moan.
"Does that feel good?"
"Yes... Please, do more..."
At her plea, I laid her down on the sofa and began to caress her body—her neck, collarbone, breasts, stomach, and thighs. I traced every inch of her with my tongue, stoking her desire.
"Ah... Professor... No... I can't..."
She writhed and moaned. I buried my face between her legs and licked the petals of her sex. Her juices tasted sweet and tart, and I lapped them up greedily.
"Ah! No! Not there—!"
She arched her hips and pressed down on my head. Relishing her reaction, I intensified the movement of my tongue. Then, I captured her nub between my lips and sucked.
"Aah! I'm coming... I'm coming!"
Her body went rigid as she reached her climax. Savoring the moment of her release, I lifted my head. She was breathless, her cheeks flushed—an expression utterly melted by pleasure.
"Shiho, you look so beautiful."
I said this to her as I began to undress. She gazed at my body, her eyes locking onto my erect member.
"Professor... it's huge..."
She murmured. I took her hand and guided it to my cock.
"Go ahead, touch it. It’s like this all because of you, Shiho."
She tentatively grasped it. Her touch made my hips shudder.
"Shiho, take off your clothes, too. Let me see everything."
She nodded and stripped off all her clothes. At the center of her slender body was a neatly groomed patch of hair, and the secret place beneath it was still trembling from the lingering traces of my caresses.
"Beautiful... Shiho, come here."
I sat her on my lap and held her close. Her skin was warm and soft. I kissed the nape of her neck and whispered into her ear.
"Shiho, I want to be inside you."
She nodded, trembling. I lifted her body and positioned myself at her entrance; it was already thoroughly wet and ready to receive me.
"I'm going in."
Slowly, I sank into her. Her insides were hot and tight, gripping me firmly. She winced at the pain but clung to my shoulders, fighting to endure it.
"Are you okay, Shiho?"
"Yes... I'm okay... Please, move..."
She gasped out the words. I held her hips and began to move slowly. Inside her, she tightened and undulated in rhythm with my movements; the sensation drove my own arousal to new heights.
"Shiho... it feels so good inside you..."
"Professor... it feels good... to me, too... Harder... please..."
She wrapped her arms around my back and began to sway her hips in time with mine. Answering her plea, I quickened my pace. The sounds of our bodies colliding and her moans echoed through the room.
"Ah! Ah! Professor! No... I'm going to come again...!"
"It's alright, Shiho. Go ahead... I'm coming with you..."
I gripped her hips tightly and drove into her with a final, rapid series of thrusts. She arched her back and cried out loudly. In that moment, I unleashed everything inside her, pouring my hot semen deep within.
Clinging to one another, we tried to catch our breath. Her sweat-slicked skin clung to mine. I stroked her hair and whispered into her ear:
"Shiho, you were amazing."
She smiled and buried her face in my chest, her expression filled with satisfaction and bliss.
We made love many more times after that. Seeing her usually serious face melt into an expression of pure pleasure was maddeningly alluring. Every time I grasped her beautiful buttocks and thrust into her from behind, she let out a sweet moan. The sensation of her long legs wrapping around my waist was intoxicating.
I savored every inch of her body, and she, in turn, embraced every part of me. I even caught glimpses of her jealous side; when a message from another woman arrived on my phone, she grew sullen and accused me. Yet, that very jealousy was proof that she desired me, and I even found myself enjoying it.
As dawn broke, exhausted, we fell asleep in each other's arms. Her sleeping face looked as innocent as a child's, and I planted a kiss on her cheek.
I didn't know how long this relationship would last. But in this moment, I had her, and she desired me in return. That was enough.
The next morning, she rose early and began getting ready. I sat up in bed and watched her from behind.
"Are you leaving already?"
"Yes. I have to get to work."
She spoke without turning around; there was a hint of sadness in her voice.
"Will I see you again?"
When I asked, she turned back with a smile.
"I'll come see you. After all, I like you, Professor."
With those words, she kissed me and left the room. I lay in bed for a while longer, lingering in the faint scent she had left behind.
Shiho Nakanishi. She had brought a new vibrancy to my life. I secretly hoped that this relationship would continue to bring happiness to us both.
