Nero's First Time
The wide hips that made one want to grab them, the slender waist that narrowed sharply in contrast, and the plump thighs and full breasts that seemed like an artistic sculpture crafted solely for a man's pleasure. Yet that very woman was now straddling me, gazing down with curious eyes. And not just anywhere—her attention was fixed on my erect manhood.
"Is this... it?"
"Yeah, pretty much."
"It got this big because of me, right?"
Every time it twitched and bounced, the tip lightly tapped against her lower belly. If that was what she meant, then yes—it had grown this large entirely because of her.
"This... really smells like Master..."
It's so strong. My head's spinning... I love it...
Her gaze was so intense and lewd that she looked ready to bury her nose against it right then and there, yet she couldn't quite bring herself to close the distance. Instead, she kept rocking her hips back and forth, rubbing herself against the air just above it. Each subtle movement made her breasts sway, and watching the sight from below while lying comfortably on the bed, I couldn't help but wonder just how fortunate a man I was.
"What should I call it?"
"Huh... Do I have to give it a special name?"
That was an unexpected question. Normally I'd just say cock, or manhood, or even dick if I was being crude. Penis sounded a bit stiff, but any of them would do. Still, hearing a refined word like that come from Nero's elegant lips and dignified voice felt... a little... just a little...
"Mm..."
It might actually be fine.
"...Cock."
"Cock?"
Damn it, I muttered without thinking.
"...So it's Master Cock, then."
"Cough...! Hack...!"
"Master...?"
Master Cock? She just tacked on the honorific like she does with me? One extra word and it sounded so much more vulgar.
"No, it's nothing..."
This was bad. I was starting to find it amusing.
"How many women have you tormented with this Master Cock?"
"...Ahem, cough..."
She poked the tip with her finger while asking, but instead of feeling scolded, my mind was completely occupied by the ridiculous title.
"I think I get it. This is supposed to go inside my hole, right...?"
But even when I try to soothe the ache by myself, only one finger fits... Will that really work in such a tight place?
"Yeah, something like that..."
At the word "tight," my manhood swelled even larger with anticipation.
"It moved on its own again... Is Master's cock... big?"
"I don't know. Maybe?"
She looked a little startled by the intimidating sight that had sprung free from my pants, and the usually bold cat had grown surprisingly docile.
"..."
Those desperate, ragged breaths I heard from above back then... this was the reason, wasn't it...?
"Like this... I just spread it?"
What if it tears...? I should open it a little wider just in case...
"Hup..."
She lifted her hips slightly and used her middle and index fingers to part her closed folds, spreading them open for me to see. I sucked in a sharp breath. Even without any foreplay, she was already glistening wet, and between the parted flesh her narrow entrance was clearly visible, twitching and leaking arousal in little pulses. That raw, unfiltered lewdness—possible only because she was so innocent—sent blood rushing straight downward.
"It looks even bigger than before..."
"...Thanks to you, Nero."
"R-really? That's good, then."
She called it fortunate that the weapon meant to pierce her virginity had grown even thicker and harder. Her body was moving on instinct, yet she still hesitated, clearly lacking proper sexual education. I needed to take the lead here...
"Now... Master Cock is going to go inside?"
"..."
Every time that crude word slipped from her pretty red lips in that lovely voice, my thoughts cut off, my breath caught, and heat flooded my face. Yet for some reason, I didn't want to tell her to stop using it.
Lying on the bed with her straddling me, all she had to do was lower her hips and we'd be joined. I found myself savoring the moment, my rigid length aching to claim her virginity.
"Want to try putting it in slowly?"
"It... doesn't look like it'll fit... Will it really go in?"
"...It might hurt a lot at first."
"I don't want it to hurt..."
Even now, she was whining that she didn't want pain. It was oddly cute.
"Should I do it instead? Want to lie down?"
"...No. I'll do it."
Even while saying that, she still showed that strange pride. It was charming.
Squelch...
"Ugh... Hn..."
It's hot... and twitching so much inside...
The tip of my burning glans pressed against her soaked entrance, which was dripping so much that the slickness was already running down her plump thighs. As I kissed the deep-pink inner flesh revealed by her spread folds, my manhood throbbed openly with the desire to be wrapped in her scorching walls and stir her up.
To make it easier for her, I guided the shaft with one hand while clasping her free hand with the other, fingers interlaced.
Press...
Encouraged, she lowered her hips a little.
"D-did it go in...?"
"Not yet."
The glans had only pushed between her inner lips and was pressing against the soft flesh inside. There was still the full length left to go; a tiny dip of her hips wouldn't be enough.
When I looked up, Nero still had her folds spread wide, eyes squeezed shut. Her trembling eyelashes were incredibly cute. Just as she said, her entrance looked too small to fit even one finger, yet it was shaped so prettily and roundly that my cock would inevitably have to force its way in.
Maybe it would be better to push in all at once... With a little help from Mini Undine, the pain would fade quickly. But looking at how stiff and frightened Nero was right now, that felt impossible.
Her desire hadn't vanished—her entrance was still drooling hungrily—but her legs trembled violently as she stayed frozen in place. I had no idea how much longer I'd have to wait. Doing it in cowgirl position for her first time really was difficult...
"Nero, maybe we should—"
"No! This is... my way of repaying you...!"
"...Huh?"
The moment I thought that, I felt something elastic tear and stretch violently around the tip of my cock. A slightly chilling sensation shot straight up my spine.
When I looked down again, Nero's hips had dropped a little lower. My glans was now completely swallowed inside her entrance. A thin trickle of blood mixed with her arousal ran down my shaft—that was the exact moment of her deflowering, burned into my mind.
"It hurts... It hurts so much... Master..."
Her interlaced hand gripped mine with enough force to make my fingers ache. Of course it hurt when flesh was being torn.
"Nero... U-ugh..."
Thanks to that, I could feel just how fiercely her hot insides were squeezing me—like my cock was being wrung out with the same desperate strength she used to clutch my hand. She was clamping down so tightly it was almost painful.
"Nngh..."
I came back to my senses from the overwhelming tightness and gently stroked her most sensitive spot, successfully helping the torn membrane around my shaft begin to heal. But the pain etched across her furrowed brow showed no sign of easing. Undine could absorb some of the negative emotions I received, including pain, but I still wasn't used to channeling the ability that far.
"Ugh... It hurts... Did the other girls... hnng... feel like this too?"
"...You did well holding on."
"Is it... all the way in now?"
It feels like a huge stake has been driven into my stomach... Ugh, it's so uncomfortable...
"No, that's... only the tip went in a little."
"Liar..."
She had finally caught her breath enough to speak, but when I told her it wasn't fully inside yet, Nero opened her tightly shut eyes to check for herself.
"...You haven't even lowered your hips all the way."
Her hips were still hovering in the air. The pain of being deflowered must have been so intense that she hadn't even noticed the awkward position.
"Ugh... Haa... Hnn..."
It's almost there. If I just lower my hips a little more, I'll really be connected to Master...
Her body, having just learned pain, refused to descend any further. Her mind and instincts were at war, leaving her waist trembling in the middle, stuck and uncertain.
Because of that, only the very tip was inside me, yet the combination of that crushing tightness and her trembling walls was forcing me toward climax far faster than I expected. If we stayed like this... I was going to come.
"Nero... Haa, you've done more than enough. Ugh, so..."
I'd have to brace myself to get hit or bitten.
Thrust...!!
"Hnyaah...!?"
While still holding her interlaced hand, I suddenly thrust my hips upward. Contrary to how impossible it had seemed moments ago, her lost balance and body weight combined to slam her soft thighs flush against my pelvis.
"....! .., Ugh...?"
"Nngh... Haa, what... tightness..."
As I forced my way through, I lost count of how many times her firm inner walls tried to block the glans like barriers. Even accounting for her inexperience and tension, the reason it felt so overwhelming was because her insides were far more winding and convoluted than I'd imagined. To push through with my rigid erection, I had to straighten every curve, and the resulting pressure was intense.
"Wait... Nero, you—"
But something more important demanded attention right now.
Twitch.
"Ugh... Nyaaah, hnng..."
While Nero remained stiff and impaled on my cock, letting out pained sounds, a pair of pointed cat ears had sprouted atop her head. Was it because the pain had been too much to bear?
"Nero... Your ears..."
"Hn... Why now... of all times..."
Even with the overwhelming foreign sensation making her lower belly ache, Nero hurriedly raised a hand to cover her head. But it wasn't just her ears. Her nails dug sharply into the back of my hand, her pupils had narrowed into vertical slits, and a long, black-furred tail had appeared behind her.
"No... Don't look..."
"No, it's..."
Her unstable transformation...
"..."
...No matter how I looked at it, she just looked like a girl wearing cat ears and a tail for her boyfriend. The twitching ears, the gently swaying tail, the slightly pointed nails and slit pupils—there was no way any man could dislike that sight. If anything, most men would love it even more.
At the very least, seeing her like this had made my cock throb even harder inside her.
Costume play. And such a realistic one at that. The irregularly twitching ears and naturally swaying tail went straight to my heart.
"Nero... It's okay. Show me."
"No, I can't... You only see me as a cat instead of a woman, don't you?!"
So I have to stay in the exact same body as Master... I have to become a proper human woman...
That was why she had always tried to hide her unstable transformation in front of me. Now I finally understood why she never let me enter her room carelessly. She always finished or released her transformation before coming out. But—
"You're... really beautiful. Just like this."
"...Hnya?"
Nero blinked in surprise, her mouth slightly open, and let out another adorable sound. She looked confused by my praise, yet she slowly lowered the hand that had been covering her ears.
"Really...?"
Her hesitant hand and trembling eyes told me exactly what I needed to say next.
"Yeah. This is a side of you that only Nero can show me, right? You're really beautiful. No man could ever hate it."
How could anyone hate it? I was the one who wanted to ask her to do it more often. The oversized cat ears and tail, perfectly proportioned to her human size, were so moving they almost felt exaggerated. I had lied a little—Rav had done the exact same cosplay before—but the original really was different. Besides...
Right now, Nero's tongue. Looking at those rough, backward-facing barbs that had appeared on it, I felt a slight shiver of revulsion even as my wicked imagination was stimulated.
"Actually... I like it."
