Chapter 88 Shirogane Aqua-sensei, The Ignorant First-Year Student
Edited by: Kanaa-senpai
Somehow, I’d ended up helping out with the first-years’ mock medical checkup.
”Then, could you go get the next person?”
”Yes, Sensei!” Emily chirped, snapping to attention like a nurse fresh out of a drama serial.
I adjusted the white coat draped over my shoulders. The thing was more costume than credential, but it made me look the part. Beside me, Emily wore a crisp nurse’s uniform—her idea, of course. She loved committing to a bit.
Flipping through the faux medical records, I barely had time to prepare before a soft knock came at the door.
”Excuse me.”
The voice was quiet, uncertain. Hisui stepped into the room with a shy little shuffle, her eyes wide as if she’d wandered into a stage she didn’t mean to stand on.
I gave her a thumbs-up, suppressing a grin. “This is going to be a very productive health check for Shirogane-sensei,” I said, in a tone meant to reassure. Mostly.
”Erm, could you take off your clothes, please?” I asked, keeping my voice clinical, neutral.
”Eh? Ah… yes…”
Color surged to her cheeks as she nodded and began to undress—hesitant fingers, a pause between each button, the quiet rustle of fabric slipping to the floor. Her movements were precise, almost ceremonial. I didn’t blink. Couldn’t. Every inch of revealed skin caught in the light like sculpture.
”She’s beautiful…” I murmured, mostly to myself.
”Eh?” she asked, startled, mid-motion.
The bra—emerald green—sat snug against her skin, a tone that suited the healthy blush in her cheeks and the subtle warmth in her thighs. She stood in just the lingerie now, her legs slightly parted, weight resting on one foot. Her stomach—softened since her idol days, no longer all edges and abs—was quietly glorious. That curve had history. She noticed where my gaze lingered and folded her arms instinctively over it.
That subtle act of shyness hit me like a lyric I hadn’t heard before. There was something exquisitely human in that self-consciousness.
”Umm… do I have to take off my underwear too?” she asked, voice barely above a whisper.
”Yes, you do,” I said gently, letting the air between us hum with tension.
She unhooked her bra with trembling fingers, revealing breasts that were full, natural, and entirely her own. She looked away as she stepped out of her panties and held them out to me, her blush now blooming across her chest, her neck.
”Sensei… is this really necessary?” she asked as I took them, the fabric warm and faintly damp in my palm.
”Yes,” I replied, my tone slow, deliberate. “It’s part of the exam.”
I spread the undergarment with clinical precision, inspecting the center, then pressed two fingers along the interior. The texture was… telling.
Her face flared scarlet. “I should’ve worn different underwear today,” she whispered, like a confession.
”What the—!” I flinched, nearly dropping the fabric.
”Sensei! Are you alright?” Emily asked, her tone high and tight, as if she couldn’t decide whether to play concerned assistant or laugh.
Always reliable, Emily. Her ability to commit to the ridiculous never failed me. I silently thanked every star for marrying her.
”Your discharge is gel-like,” I noted, examining my fingers.
”Is that… bad?” Hisui asked, eyes wide with concern.
I softened my voice, settling into the calm cadence I used when soothing nervous students—or frightened animals.
”Calm down and listen, Hisui-chan. Right now… your body is in an extremely fertile state.”
”Pregnant?!” she gasped, stepping back like the word had physical weight.
”No, no,” I said quickly, sitting up straighter and meeting her gaze. “But it does mean your body’s ready. Biologically speaking.”
I let the pause stretch, watching how her breathing changed, how her hands fidgeted.
”Do you have any pregnancy desires, Hisui-chan?” I asked, eyes locked on hers.
”Y-yes! I’d love to have lots of babies someday!” she blurted out, voice high and sincere.
Lots. My chest did a slow, dangerous twist at that.
I turned toward the computer and input her words with studied seriousness. Strong desire for pregnancy. Hopes for multiple children.
”So, you’d prefer intimacy without contraception, and you’d want the man to…” I paused. “Finish inside you, right?”
”W-what’s a contraception…?” she asked, genuinely perplexed.
Emily and I both collapsed—figuratively, into laughter. Literally, onto the ground.
Too much. Too damn cute.
She tilted her head, watching us with mild concern. “Sorry, I don’t really understand what you mean by ‘Finish inside’ either… I’m sorry!”
I wanted to protect that innocence. Lock it in a glass case and hide the key somewhere no one could ever find it.
”Have you ever had sexual intercourse with a man?” I asked, carefully, gently.
”Eh?”
”I mean, have you had any sexual experiences with males?”
”N-no!”
Exactly what I needed to hear.
Thanks to Emily’s customized exam interface—God bless that woman—we had a secure place to record this level of detail. Claire, Kanon, Kotono—they’d all sworn Emily could build anything in a day. They weren’t wrong.
”When you hold hands with a boy, does that count as sexual contact?” I asked, half-teasing, half-curious.
”I mean, I have… I once held hands with Sensei,” she said, eyes flicking up to mine, “but I’ve only ever held hands with him…”
Emily made a strangled noise behind me. I was barely holding on myself. This girl was a lethal dose of earnest.
”Alright then,” I said, my voice dropping an octave. “Do you know the proper way to have intercourse with a man… to make a baby?”
Hisui blushed violently and shook her head. “I-I don’t know…”
She closed her eyes like she expected to be scolded.
”Shirogane-sensei, the first-year curriculum might not have covered this yet,” Emily said, diplomatically.
I nodded. “What about the new textbook? How far have you studied?”
”Uh… it was about touching p*nises.”
Ah yes. The part where I’d demonstrated technique using a rubber model. Thorough, but clearly not comprehensive.
”Alright, let’s have you touch p*nis-san here, then.”
”Eh?!”
I undid my belt and lowered my pants—slowly, deliberately—keeping my expression neutral, even academic.
”Excuse me…” she murmured, reaching out with careful hands.
She held me like she might a microphone, or a bird.
”How does it compare to the school model?” I asked.
”It’s completely different!” she breathed. “It’s hot… hard… and the sensation is so real.”
My body responded before I could will it otherwise. Of course it did. I was human.
”You realize what an erection looks like now, right?”
”Eh? … Umm… Is it… getting excited because of me?”
Perfect. Utterly perfect.
Emily clapped quietly behind me and leaned down to whisper, “Hisui-chan, when a boy gets an erection, you have to take responsibility and deal with it.”
”Eeh?! S-So that’s how it is?” she stammered, eyes darting between my face and my groin.
”I’m sorry! Is this my fault? If so, I’ll take responsibility! Um… what should I do?”
The warmth of her nervous palms spread through me.
”Try stroking it. Slowly. Up and down,” I said, voice low and even.
”O-okay…” she whispered, fingers trembling against me.
She started moving—tentative, unsteady strokes, like she was learning an instrument by touch alone.
”Hisui-chan, shall we have a one-on-one s*x education lesson in another classroom?” I asked.
”Thank you!” she said earnestly, nodding with both hands still in place.
I layered my hand over hers, guiding her movements with care.
”Like this,” I said, adjusting her grip. “Firm, but not tight. Up and down. Steady.”
”Wow,” she murmured, eyes wide. “There’s a… slimy fluid coming out of the tip…”
She stared, fascinated.
And I knew, with absolute certainty, that this—this—was why I could never stop teasing innocent girls. Not to break them. But to witness the exact moment their wonder bloomed.
At that moment, I decided deep inside that today would finally be the day I would gently cross the threshold with Hisui-chan.
”This,” I whispered close to her ear, my voice low and tender, “is your body asking for something it’s never had before.” I let my hand hover, feeling the rising pulse beneath my skin. “Look how it arches toward you, eager.”
”Wow, it’s incredible… so different from before,” she breathed, her voice soft, eyes wide with a blend of curiosity and awe.
I lowered my face nearer, so close she could feel the warmth of my breath against her skin. “This curve,” I murmured, “is the part that will enter you, where the two of us will connect.”
My fingers traced a careful path, reverent and gentle. I could see her imagination working, the flush blooming across her cheeks as she nodded quietly, wordless but understanding that this would feel like something wholly new—something good.
Her reaction stirred something fierce inside me. The swell of desire was sudden, urgent. I slid my hand away and took hers, guiding it gently to where I was most vulnerable.
”This is where it begins,” I said softly, “where life stirs quietly beneath the surface. Feel it with care.”
”Eh?” Her fingers trembled as she touched, astonished by the subtle warmth and softness. “It’s… alive. You really made this… for me?”
I nodded, a slow, steady affirmation. It felt like a sacred duty—an offering made with deliberate intention, a gift for when the moment came.
”Um… Sensei,” she said suddenly, voice tentative. “Since a while ago, my lower belly’s been warm, almost burning. Is that… normal?”
I glanced briefly toward Emily, who stood nearby with a knowing look—her own feelings for Kanon clear in her eyes. Emily leaned in, her voice a gentle murmur in Hisui-chan’s ear.
”That warmth,” Emily said softly, “is your body’s way of saying it’s ready, longing for something new.”
”R-Really?” Hisui-chan’s disbelief was genuine, her eyes sparkling with a new understanding.
I met her gaze, steady and calm. A man’s mind must remain clear even as his body burns with desire. “Yes. And more than that, do you feel a tingle deep inside?”
”Yes,” she whispered. “That thick, curved shape… just seeing it, I can’t think of anything else. Is that strange?”
Emily shook her head gently, her smile warm and reassuring—as if to say, you’re exactly as you should be. If only this moment could be captured forever. She would be a goddess frozen in time, radiant and serene.
”It’s natural,” Emily said. “Every girl who sees Aqua-sama like this feels it—the pull. Even Kanon hides it behind a composed smile, but she thinks of him always.”
”R-Really?” Hisui-chan’s breath caught, trembling with a rush of emotion.
In that instant, my own thoughts echoed hers. Hisui-chan’s mind is filled with this desire too, isn’t it?
”Y-Yes,” she whispered, cheeks aflame.
The heat in me deepened, a slow, relentless flood. I could feel it gathering, pressing against restraint.
”When you feel this part of me inside you,” I said quietly, “you’ll find your thoughts drawn to it, captivated by the sensation.”
”Eeh? So good…” Her voice was fragile, almost breathless, a mixture of wonder and hunger.
Emily’s subtle encouragement had awakened something fierce in her eyes. It was innocence mingled with yearning—a beautiful contradiction.
I rose from the chair and took her hand, guiding her gently down onto the examination table.
”All right, Hisui-chan,” I said, my voice steady but charged with intent. “It’s time for a real lesson—with your body, teaching you how to create something new.”
”Y-Yes, I understand,” she replied, voice barely above a whisper.
The moment shattered my last reserve. I shed my clothes with a quiet urgency and leaned over her.
”A-ah…” Her breath hitched, an unguarded sound slipping free.
My hands moved to her breasts, pressing softly, coaxing a sound from her lips—a note of vulnerability and discovery. She gasped, startled by the unfamiliar voice emerging from her own throat, then hid her face in a shy flush.
”I want you to feel—truly feel—that you are a woman,” I promised, voice low and deliberate.
”Haa… hi…” she answered, trembling.
I moved with slow, steady rhythm, careful not to overwhelm her. Our connection deepened, and I could feel her slickness gathering between us—a quiet, wordless consent.
”Hisui-chan, do you know about mas***bating?” I asked softly.
”What’s mas***bating?” she murmured, brows furrowed.
Emily, close by, leaned in with a quiet smile. “I’ll explain that part, Sensei,” she said gently, “that’s a woman’s role.”
Her confidence settled something in me. Some lessons were better entrusted to a sister’s hands.
I turned back to Hisui-chan, my fingers coated with the moisture of our closeness, and tenderly prepared her for what was to come—slow, measured coaxing, easing away any hesitation.
”Nn… Ah…” Her breath fluttered, surprised by the new sensations awakening within her.
Her expression flickered between confusion and embarrassment—an exquisite hesitation—before settling into quiet trust.
The way was slippery and sure now. I could hold back no longer. This was the moment I would take responsibility for.
”Relax, Hisui-chan,” I urged softly. “Like before your performance, let yourself go.”
”Y-Yes, Sensei,” she breathed, the stiff tension leaving her frame.
Her body was incredible—responsive and brave. At my words, the tension melted, and her muscles softened.
I met her eyes and began to move slowly, inch by inch, careful to respect the fragile boundary between them.
”Unn!” A sharp flicker of discomfort passed across her face as the last veil of innocence gave way.
I memorized that moment—the look that spoke of pain and courage entwined. A man should never forget the face of the girl whose heart he first touched in that way.
”Are you all right?” I asked gently.
”I’m fine…” she replied, voice steady though her eyes betrayed a quiet struggle.
She was strong. She reminded me of someone else—someone who had endured much and smiled through it all.
”Now,” I said softly, “we’ll learn together what it means to move in harmony.”
”Please teach me,” she said, voice filled with trust.
I shifted with care, mindful of every nuance—each subtle shift inside her a language I was eager to understand.
It’s the same whether they’re orthodox idols or princesses.
”Ooh…”
Hisui-chan’s breath caught unexpectedly, a soft, startled sound slipping out before she covered her mouth with both hands.
I could feel it—her warmth marking me in a way I couldn’t ignore. The person I admired was here, imprinting herself on me.
No man could keep his composure now.
My hands gripped her hips firmly, lifting her just enough. With measured intensity, I shifted my rhythm, deeper and steadier—like the slow, deliberate press of waves pulling inward.
”Ahh, ohh, nn… mas***bating… Wait…”
Her expression flickered between raw surrender and shy resistance, her head shaking softly side to side.
A man wouldn’t be human if he didn’t feel this pull.
The surge inside me built rapidly, urgent and fierce.
”Sorry, Hisui-chan,” I murmured, voice thick with need, pressing close enough for my words to brush her ear. “Sensei can’t hold back any longer. I’m going to leave everything inside you. This is all for the sake of making a baby, right? So it’s okay?”
”Y-yes,” she whispered back, breath trembling. “I want to have lots of babies, thank you.”
Her body, once untouched, responded with a fierce embrace—every inch clinging to me with desperate fervor.
It was exquisite, the way she folded around me, tightening like a secret vow.
She was asking without words—begging me to surrender.
I answered with a wild urgency, moving with a force that scattered reason to the winds.
”Ooh, ah… uhn… ah, oh… what… ah…!”
Nearby, Emily’s quiet voice drifted to Hisui-chan’s ear, a whispered encouragement like a breeze stirring leaves.
”Ah, oh… I’m… Ah, yes… I’m!”
I timed my own release with her first wave, pouring everything into her in a single, relentless flood.
Throbbing… pulsing… alive…
The warmth swelled within her, filling every hollow until it spilled over, marking us both in silent testament.
Slowly, I withdrew, freeing her from the tension that had bound us so tightly.
”Sorry, Hisui-chan,” I said quietly, breath still heavy. “That was rough for your first time.”
She shook her head gently, cheeks flushed with something tender and fierce.
”N-no, it’s my fault for not being able to control myself.”
Sitting up, she glanced down at the trace of me left behind.
”Ah, um… this act is such a wonderful thing… Even though it’s supposed to be just for making babies, when you were inside me, my head spun… I’m sorry for… making those sounds.”
It’s fine, it’s fine. This was fine, wasn’t it?
I looked at her—soft and spent, still lying on the bed—and felt a rush of something close to despair.
I’d let myself be carried away by her sweetness. Ten rounds of reckless passion with someone so innocent.
Not only had I filled her, but I’d marked every inch, even pushed her into new experiences too soon. But despite it all, her eagerness shone through.
”Leave this to me, Aqua-sama,” Emily said with calm efficiency.
”Eh, Emily?”
True to form, she cleaned up and tidied the room in no time at all—a guardian angel in every way.
When Hisui-chan came back to herself, I offered a soft apology.
”I’m sorry, Hisui-chan. But as atonement, I promise to be the father of your children whenever you wish. Please, don’t hesitate to tell me when you want to try again.”
”Y-yes! Thank you so much!”
Her innocent smile was like sunlight through stained glass—too bright for me to meet for long.
She was pure, lovely. Emily and I exchanged a glance, quiet and knowing.
”Alright then,” I said, voice low. “Come back to me when your period stops. Or rather, come even if it starts.”
”Yes, I will!”
Hisui-chan stood, gave a small bow, and left the infirmary.
Huh, it’s just begun, but I’ve already spent more time with the first patient than expected.
But she was so cute—it couldn’t be helped, right? Yeah, yeah. It couldn’t be helped.
I flipped through the chart Emily had prepared, ready for the next visitor.
