Chapter 1
"Well then, Professor, let's take our time to chat again next time. Good night."
The seminar, which had dragged on until nearly evening, finally reached its conclusion. Tidying up the table as she bade her farewell was my sole seminar student—a young woman.
Her name was Sana Nakamura, a student belonging to my research lab. Standing around 160 centimeters tall, she had a boyish cut of black hair paired with a slender, delicate frame. While her neat facial features were somewhat understated, her glasses lent her an distinctly earnest, studious aura. That appearance, however, could drastically transform at the slightest trigger.
"Alright then, Nakamura-san. Good work today. Our next meeting is next Tuesday. Don't forget."
"Yes, I won't forget. Well then, I'll see you next week."
As she made her way out of the lab, I offered a slight nod to see her off. She stepped out into the hallway, writing down the details for next week's meeting in her planner as she walked. Watching her back as she departed, I let out a low sigh.
Takumi Nagai. At fifty-eight years old, I am a university professor by profession. My research revolves around ancient history, specializing in the period spanning the Nara to Heian eras. Generally speaking, it is a profession that commands a serious, rigid image, but it would be no exaggeration to say my private life is the polar opposite.
Ever since my student days, I carried a reputation for being bad with women. That didn't change even after becoming a professor; to date, I have been involved with numerous women. Among them, even students on a few occasions...
Sana Nakamura was one of them. She was a student in my seminar, but our relationship extended far beyond that of a mere professor and student. She was my mistress.
(...Mm, it's been a while since we could talk like that.)
Swaying in the train on my way home, I chewed over my memories of her. I met her last autumn, shortly after she had joined my seminar.
Back then, she was even more plain-looking than she is now. Black-rimmed glasses, messy hair, and clothing mostly limited to drab, muted colors—nothing about her stood out. Yet, her attitude toward research was sincere and passionate. Her presentations in class possessed a level of quality that set her apart from the other students.
Taking note of her exceptional ability, I decided to tutor her individually. That was the spark of our relationship. She followed my guidance with utmost dedication, gradually opening her heart to me over time.
Then came a certain night. Left entirely alone together in the research lab, she suddenly confessed her feelings to me out of nowhere.
"Professor... I'm in love with you."
Her words caught me off guard. At the same time, however, a surge of desire for her bloomed within me. She was twenty-two at the time—more than thirty years my junior. Yet, looking into her earnest eyes and seeing her shyly seeking my affection, I couldn't bring myself to resist.
"Nakamura-san... are you truly sure about someone like me? I am far older than you, and I have a wife."
"I don't care. I love you, Professor. I won't cause any trouble for your wife. If you want me, I'll do anything you ask."
Her words were dead serious. Yielding to her fierce resolve, I held her in my arms that very night. She was a virgin, yet her body sought me with a ravenous hunger that completely captivated me.
Ever since, we have maintained this secret affair. At the university, we act strictly as professor and student; outside those walls, we devour each other's bodies as lovers. She called me "Takumi-san," and I called her "Sana."
(...I wanted to see her today, too.)
Gazing at the night cityscape scrolling past the train window, my thoughts drifted to her. Recently, she had begun performing as an underground idol. Her group was still obscure with a tiny fanbase, yet she threw herself into those activities with incredible passion.
Her stage outfits were mostly flashy, paired with heavy makeup. In that attire, she looked like a completely different person from her university self. Yet that striking gap drew me in all the more.
(...I hope I can see her tomorrow.)
Looking forward to our rendezvous, I hurried on my way home.
The following afternoon, I was visiting her apartment. Her room was located a bit of a distance from the university, nestled in a quiet residential neighborhood, and felt rather spacious for someone living alone.
"Takumi-san, welcome!"
When I rang the intercom, she popped her head out. She was dressed plainly today, just like at the university, but a warm smile greeted me on her face.
"Sana, sorry to drop in on you."
At her invitation, I stepped inside. The room was neatly organized and carried an immaculate sense of cleanliness. She ushered me into the living room and poured me a cup of tea.
"Takumi-san, what brings you here today? It was so sudden."
"Well, I just wanted to see you for a bit. You have a live show tomorrow, right? I thought I'd go support you."
"Eh, really? I'm so happy! But... is that alright? Won't your wife find out?"
"It's fine. I have a university meeting tomorrow anyway, so I'll just stop by on my way back. Besides, the theater you're performing at happens to be a venue I frequent."
I laughed off her concern. She always worried about my wife. But in reality, my wife had no idea about my infidelity; if anything, she trusted and respected me completely. While a quiet pang of guilt accompanied that truth, I continued my relationship with Sana nonetheless.
"In that case, I really look forward to tomorrow! Knowing you'll be there, Takumi-san, I'm going to give it my absolute all on stage!"
She let out a delighted laugh. That innocent smile struck a deep chord in my chest. She loved me from the bottom of her heart—a fact that brought me immense happiness, yet tortured me all the same.
"Sana... do you truly love someone like me?"
"Yes. I love you so much. I love you more than anyone else, Takumi-san."
She answered without a second's hesitation, her gaze unwavering and completely sincere. Unable to resist the intensity in her eyes, I reached out and took her hand.
"Sana... thank you. I love you, too."
I pulled her by the hand, drawing her close to me. Offering no resistance, she melted right into my embrace. I held her slender frame tightly against me.
"Takumi-san... I love you. I love you so much."
She murmured the words repeatedly against my chest, her sweet voice melting my heart. I buried my face in her hair, breathing in her scent.
"Sana, I want your body."
"...Yes. It belongs to you, Takumi-san."
She nodded shyly. I claimed her lips and kissed her deeply. Her tongue intertwined with mine as we tasted one another.
"Mmm... ngh..."
She responded to my kiss, letting out a sweet sound. I carried her to the bed. Once I had undressed her completely, I couldn't hold back and began raining kisses over her smooth, white skin.
"Ah, Takumi-san... that spot... it makes me feel so much..."
As I trailed my tongue along her neck, collarbone, and the tips of her breasts, she shuddered and let out a sultry moan. Relishing her reaction, I continued to caress her entire body.
"Sana, you're beautiful. No matter how many times I see it, your body is stunning."
"...Takumi-san, please don't say things like that. It's embarrassing..."
She blushed and closed her eyes. Her expression was incredibly arousing, stoking my desire even further. I took the tip of her breast into my mouth and rolled it with my tongue.
"Hya... ah... ngh... no, don't lick there... I'm going to lose my mind..."
"Sana, you're so cute. It's okay to feel it—let yourself go. I'm going to make you feel amazing."
Kneading her breasts with both hands, I sucked firmly on her nipples. She arched her back and gasped.
"Ah... ngh... Takumi-san, I can't hold back anymore..."
She gazed up at me with teary eyes. I kissed her face and whispered into her ear:
"Sana, I want to go inside you. I want to put myself inside you."
"...Yes. Put yourself inside me. Fill me up completely."
She nodded. I spread her legs and traced my fingers over the center of her. She was already wet, and she welcomed my fingers with ease.
"Ah... mm... Takumi-san's fingers... sliding in..."
"Sana, you're tightening around them. It feels so good."
I moved my fingers inside her, stimulating the walls within. She cried out and her body trembled.
"N-no... Takumi-san, fingers aren't enough... please... put *yours* inside me..."
She gazed up at me, pleading. Unable to hold back any longer at her words, I lowered my trousers and positioned myself between her legs.
"Sana, I'm putting it in."
"...Yes. Please."
I slowly inserted myself into her. Her hot, tight interior clamped down on me; the sensation made me catch my breath.
"Ah... aah... it's going in... Takumi-san's is inside me..."
She, too, accepted me and let out a sound of satisfaction. That sound aroused me further, and I quickened the pace of my hips.
"Sana, does it feel good? Can you feel me?"
"Yes... it feels so good... Takumi-san, yours is so big and hot... it's reaching deep inside my belly..."
She answered while moving her hips in sync with mine. Fueled by the sight of her, I thrust harder and more intensely into her.
"Sana... Sana... I love you. I love you so much."
"I love you too, Takumi-san... go harder... make me yours..."
Calling each other's names, we joined our bodies with intense passion. She grew hotter and hotter, tightening around me ever more fiercely. Overwhelmed by the sensation, I finally reached my limit.
"Sana... I'm coming... I'm going to come inside you..."
"Yes... give me all of it, Takumi-san... put it all inside me..."
At those words, I released my heat deep within her. She reached her own climax at the same moment, her body tensing up.
"Ah... aah... it's coming... I'm coming... Takumi-san, your heat..."
Tears streaming from the sheer pleasure of her climax, she clung to my back. Holding her close, I poured every last drop into her.
"...Haa... haa... That was amazing, Takumi-san."
"You were amazing too, Sana."
We held each other as we caught our breath. Her sweat-slicked skin was incredibly alluring, and I found myself impulsively kissing her cheek.
"I love you, Takumi-san. I want to be with you forever."
She murmured this while burying her face in my chest. Her words made my heart ache with a bittersweet pang.
"Sana... I want to be with you too. But I have a family. I can't make you unhappy."
"...I understand. That's why things as they are are fine. As long as you love me, Takumi-san, that’s enough to make me happy."
She wore a smile that seemed to hold both resignation and contentment. That smile made my heart ache.
"I'm sorry, Sana. I wish I could make you happier."
"It's okay. Just hold me, Takumi-san."
She snuggled deeper into my arms. I held her slender body close, filled with affection.
We stayed like that for a while, holding one another. The setting sun bathed the room in an orange glow. In that light, I could hear the sound of her breathing as she drifted off to sleep. Gazing at her peaceful face, I gently stroked her hair.
"Sana, you really are a wonderful person. I’m sorry I couldn’t make you happy."
I whispered these words of apology to her, but she was already asleep, and they never reached her.
I gently pulled away from her and began tidying up the room. I had to leave before she woke up—and I had to get home before my wife started to worry.
"...Let's meet again, Sana."
I planted a final kiss on her as she slept in the bed, then left the room. Walking alone through the twilight streets, I etched the time I had spent with her deep into my heart.
I didn't know how long this relationship would last. But the time shared with her had been the most brilliant period of my life. Holding that truth close to my heart, I walked the path back home.
