I Ate Well... No—I Got Eaten?
I'd only meant to rest it on Erina's belly for a moment before heading straight for her pussy.
But Erina stopped me cold.
"What's wrong, Erina?"
"Professor… your cock… it's past my navel… A-are we really… going to…?"
"That's why I got you so wet first."
Besides, it wasn't like this was the first time she'd seen mine. Why the sudden fuss?
"E-even so… seeing it with my own two eyes like this… it changes how you feel about it…!"
"Don't worry."
"Huuuh…?"
I shifted back a little and lowered her legs again before I spoke.
"Can you trust your professor a little? —Come on, Erina. Lift one leg for me."
I asked her to raise a leg herself.
I'd originally considered hoisting both of them, but my mind changed on the spot. This was her first time. A somewhat gentler pose—one that still left room for a little romance—would look prettier.
Kneeling on the bed and looking down, I could see Erina's naked body laid out so demurely. She looked like a pristine stretch of white snow, a spotless canvas unfurled without a single speck of dust.
From that quiet recline, she finally did as I'd asked—folding and lifting her right leg—and looked up at me.
Gazing down at her like that stirred thoughts I really shouldn't have been having.
What if I just slammed it in rough right now…
…Ugh. No. Absolutely not. That was a one-way ticket to being called a complete maniac. Beyond that, she might be so disgusted she'd report me and brand me a criminal.
And even setting all of that aside—how could I go for something that aggressive when this was the first time for both of us? Who knew what kind of mistakes I might make.
Absolutely not.
"Erina."
I took the leg she'd lifted for me in my left hand and held it.
"…Nnh. Yes, Professor."
"It's really going in soon… get yourself ready."
"Yes…"
Erina was ready. So was I.
All that remained was penetration.
Steeled with that resolve, I took my cock in hand—only to find Erina's pussy had already clenched shut again. But at this point, what did that matter? The inside was thoroughly soaked; a little resistance was no problem at all.
Between the thick outer lips locked snugly together, completing a single unbroken line, I pressed the head down with a careful bit of force. A faint moan slipped from Erina's mouth.
Of course it was tense. This was the first time our sexes had ever truly touched—a once-in-a-lifetime moment. My own heartbeat was pounding so hard I half-worried it would get in the way of the main event.
But for this moment, I decided not to care.
The glans I'd pressed into the seam of her outer lips slid down to the midpoint. Using the head of the cock I was holding, I stirred and pried that cleft open to either side.
And at last—not raw outer flesh, but the true mucosal entrance of her vagina waiting beneath—the tip of my glans kissed it.
"Nnh."
Erina reacted faintly, unsettled by the unfamiliar sensation washing over her again. Watching her, I put a little more force behind the cock already working its way past her folds and pushed in.
Schlick.
I was definitely pushing into the same hole my fingers had just been inside. And yet, through the head forcing its way in, I could feel it was going to be tighter than expected.
So when I put real strength into it—
Sssliip—
Kh.
More than half the head vanished into her pussy in a single gulp, as if the earlier resistance had never existed.
"Mmhnnn…"
The head was fully inside now, seated and locked.
…No one can argue this is in.
Erina let out a short, unpracticed moan at the foreign weight of something spreading her open and filling her—but once we'd come this far…
Stopping was no longer an option.
I steeled myself and pushed a little farther forward.
Thuck.
"…Hhk!"
"…What?"
It felt like I'd hit a wall—like the head of my cock was already being crushed against something right in front of me.
…No. That couldn't be right. A woman's vagina couldn't be that short.
Had I angled wrong? I tilted the cock slightly upward and drove forward again.
Tudduk!
Something gave—a sound like a tear.
"Huh?"
"Ah—ahhnnnngh…!"
Erina's face twisted as if she'd been struck by sudden, searing pain, a moan that was almost a scream tearing out of her.
And the sensation from below… the wall that had been blocking my advance collapsed all at once. The crushing pressure on my glans vanished, and the cock surged forward so abruptly I had to slam on the brakes with a panicked whoa.
…Holy shit.
I'd just broken her hymen.
I flicked a glance downward, and sure enough—a thin thread of blood was already trailing down her thigh through that narrow gap.
I should have at least said something before I punched through. Without any warning—
"P-Professor…"
"Ah—yeah. Erina. I-I'm sorry."
"Your… really is too big…"
"No… more than that…"
"…I know."
"Hm?"
Know what?
"Just now… that was my hymen tearing, wasn't it?"
"So you knew."
"Father always said… a girl's virginity is something you only give to someone truly precious."
She went on, tying it off with, "Back then I didn't really understand what that meant… but I think I do now."
Sir… I'm so sorry…
"Nngh."
"I'm… happy. Whatever form it took, I got to give it to you, Professor. So I think that's enough… Hehe…"
Saying that, Erina lightly wiped away the tears welling in her eyes—probably from the shock of the tear itself. It made sense. This wasn't some trivial scrape; the living membrane of her own body had been torn open. Of course it hurt.
"Please move… Professor."
"Hm?"
"I-I'm… okay now."
Putting on a brave face…
"All right."
Unable to refuse her request, I gave a small smile and started moving again, carefully.
Schlick.
"…Mmh."
There was plenty of wetness, no question.
But damn, she's tight…
Compared to when I'd worked her with my fingers, the slick heat wrapping my cock was on a completely different level. And yet it was still this snug. That meant she was clamping down hard—so hard that if I let my guard down, it felt like she might snap me clean off and refuse to let go.
Thankfully, her body kept pouring out enough love juices to keep things sliding. I only rocked my core forward and back in small motions, but every time, my cock traveled the full distance from her entrance all the way to the mouth of her womb, churning her thoroughly.
"Hhk, hngh…! P-Professor, every time your cock moves, it keeps thudding, thudding against my womb…!"
"Erina… your word choice is a little… khh."
Every time she drew a breath in and let it out, the squeeze around my cock spiked. When she breathed evenly it was rhythmic; when she gasped, it turned irregular. Being the one crushed from inside her… this was harder work than I'd expected.
I held the thigh of her raised leg just below the crook of her knee with one hand and kept thrusting. The pussy my cock was sliding in and out of—the swollen, flushed inner lips, the thick outer ones cradling them—every last detail was obscenely erotic. How did a body this lewd even exist…
With that thought, my free hand groped one of her breasts, kneading as I continued to drive into her.
"Ahnngh… Professor, you really… do love breasts… haah… nngh…"
Separate from the cock still plunging in and out of her pussy, I worked her soft mound until I caught the nipple at its peak between my fingers and twisted, pinching hard.
"Ahh—nngh, nnnngh—!!"
Erina couldn't hold it in. A cry thick with pleasure rang through the room as she wailed. Her pussy clamped down again.
Ugh…
At this rate, I was going to…
If this had been my real body back in my original world, I would have finished a long time ago under pleasure like this. But Kyle's body—just how tough was it? How composed? I could only marvel at how well it withstood the onslaught.
"Hhk, hngh… ahn…"
Erina's face was steeped in bliss as well. Every time my cock knocked against the mouth of her womb, one eye would squeeze shut with a moan—but overall…
She's enjoying this.
Thankfully, I seemed to be doing all right. Maybe I could allow myself a little confidence.
"Aaahn… Professor's cock is packing me so full… hngh, the way it scrapes my walls feels so good… nngh…!"
"Mmhnn…"
But I was genuinely approaching my limit now. The urge to come was climbing in earnest, and my breathing was turning rougher by the second. No matter how well this body held out, hearing her say things like that during our first time—pressed against me like this—would break anyone's restraint.
"Ahn…!"
As my breathing roughened, so did the way my cock slammed in and out. Controlling my strength was getting harder… Rough meant losing composure. Losing composure meant both speed and force slipped free of careful pacing and locked into a faster tempo.
"—Khh, Erina…"
"—Y-yes, Prooofessor…!"
She answered with difficulty between ragged breaths.
"Soon… any second…!"
"Y-yes…! I don't really know what, but… I'll take all of it…! If it's you, Professor…!"
Khh.
This was truly the end of the line. Feeling the limit hit, I hauled the thigh I'd been holding tight against me so I could finally pour out everything I'd been holding back.
The close press sealed our joined sexes flush together. My cock reached straight to the mouth of her womb at the deepest point—and still tried to force that wall farther open, pushing for more.
And in that state, semen surged out through the slit of my glans.
"Ahhnnnngh—!"
"Khhh…!"
Suck… it's pulling me in……!!
A fierce torrent of cum. The head still spurting and the entrance to her womb were sealed together like a kiss. Thanks to that, the semen kept pouring until her womb was completely full.
