A Happy First Experience ♥
As the number of tentacles spanning my vaginal entrance increased, the hole slowly stretched open. It felt just like using a vaginal dilator to widen my pussy. A thick wave of disgust flooded my mind.
"Mmm...! So this really is your first time, huh? I've fucked countless women, but I've never seen such a pretty little hole! Not a single sign it's ever been used!"
"Khrrgh... ♥"
Did it think I was lying? The tentacle, having confirmed my virginity firsthand, wriggled in response across my body.
"From today onward, I'll torment you slo~wly~ ve~ry ve~ry cruelly~"
"Hik... hiik...!"
"Since it's your first time~ let's start light~"
The pressure prying my pussy open vanished, and in its place, a single thread-thin tentacle so fine it was hard to notice burrowed into my vagina.
"Khrrgh... ♥"
The sensation was strange... The filament-like tentacle grazed my vaginal folds, meticulously mapping every nook and cranny. Finally, it pressed against my cervix, giving the narrow opening a light squish~ before slipping inside.
"Haaaang..."
A lewd moan escaped me like a sigh, and all strength drained from my body. My knees buckled, and I collapsed unintentionally into a doggy-style position, panting for breath.
"Kkh... hiiik... ♥"
A chilling stimulation I'd never felt in my life. The kind of cervical penetration no human partner could ever achieve. Even though it was paper-thin, the tentacle's movements registered with crystal clarity. No, I had to feel them... ♥
"Grroan... ugh... groooan..."
The tentacle that had invaded my cervix deliberately swelled against the inner walls. It slithered along the fallopian tube, prodding my ovary.
"Khiik... ♥"
A dizzying stab of pain, like a needle prick. This time, the agony hit harder than any pleasure. Sensing that, the tentacle thrashed like an eel, scraping my vaginal folds and uterine walls.
"Haaak... haaang... ♥"
The pain vanished in an instant, replaced by delicious pleasure. The tentacle's expert motions continued relentlessly. All those women it claimed to have fucked? It didn't seem like a lie anymore. It felt like it knew every secret weakness I didn't even know I had.
"Khrrgh... ♥"
An hour...? Maybe even longer had passed. The relentless tentacle finally stilled.
"Perfect! Airi, your body's in incredible shape! You'd pop out a ton of healthy babies if you got pregnant!"
"Ugh..."
"It'd be a shame to ruin such a pretty hole all at once, right? There's fun in remodeling it step by step~"
"R-Remodeling...?"
It sounded like something no one should ever say to a person. Terror seized me; I couldn't control my convulsing body.
"For today, how about we start with a light pussy orgasm? Feel a woman's joy! Oh, I won't break your hymen! I want to ripen you slowly so eventually you beg me to fuck you...!"
"T-That'll never... hiiik ♥"
The wicked tentacle ignored my words completely. Another thin tendril burrowed into my pussy, just like before, pushing all the way into my womb.
"Aah... haak... hawook...?!"

The feeling... it was even stranger than before...
"Wait, stooop... haaak... ♥"
I pleaded, arching my waist, but the writhing tentacle didn't stop.
"Kkh...! Ugh... ♥ Nooo..."
A heavy mass filled deep in my womb, a weighty pressure settling in. It should have hurt, but bizarrely, it didn't. Instead, a creeping pleasure welled up.
I instinctively clenched my lower belly, feeling a jelly-like squish.
"Khuuk ♥"
Just one squeeze of my pussy, and a terrifying surge of dangerous pleasure exploded. It was like it was pressing right on a weakness I never knew I had.
"Uuugh..."
No sooner had I spoken than the tentacle hardened. A rock-solid foreign mass pressed vividly against my insides.
"Hak... ♥"
The tentacle molded perfectly to my vagina and uterus, clinging without budging, like it was taking a cast of my pussy.
I clenched reflexively and felt a sharp pain, thrashing my body.
"Nooo..."
The unwelcome voice stirred my hazy mind. I didn't want to do what the tentacle wanted. But against my will, my pussy entrance fluttered, craving even more pleasure.
"Ugh... khrrgh... ♥"
My lower belly trembled like I was getting low-frequency therapy. I could feel the tentacle wriggling between my vaginal folds.
"Hiiik... ♥"
My womb too. I could sense its shape and size—things I'd never wondered about and never wanted to know. Right below my navel. A woman's most precious baby room. Every time I clenched my pussy, my womb quivered in tandem, spreading dangerous pleasure.
"Hk... hiiik... ♥"
Twitch. Hearing the tentacle's words, my movements halted. Shame I'd forgotten in the ecstasy crept back up.
"Nooo..."
Just as the tentacle said, my current姿势 was utter vulgarity, something I could never show anyone. Face-down in doggy style, leaking lewd gasps while making my pussy flutter like a whore.
I wanted to resist, but...
"Khaaaang... ♥"
I had no right to refuse. Any hint of defiance, and the tentacle inside me would rampage.
"Yesss... ♥"
My will to resist shattered completely. I had no choice but to obey. Not even entertaining rebellion, I fluttered my pussy amid intense humiliation.
"Uht... haa ♥"
Even amid the humiliating praise and mockery, I didn't stop fluttering my pussy. It was the only thing this powerless me could do.
"Kkh...?!"
Ten minutes of pussy clenching. Suddenly, my body jerked upward, fireworks exploding in my mind. All stray thoughts vanished, my head clearing like a fresh snowfield. At the same time, the pleasure from my pussy sharpened intensely. It grew too strong to endure... ♥
"Haaak...! khiik...!"
"Khaaaak... ♥"
Climax? It was already satisfying enough... If it got any stronger, I'd surely pass out.
"Nooo... stooop..."
My mouth denied it, but I didn't stop clenching. Because I wanted to experience a woman's climax.
"Huuht... uht..."
The tentacle, sharing my thoughts, mocked me with contempt. This time, I didn't deny it. No, I couldn't.
"Hooook... khrrgh... ♥"
Pucker, release. I clenched and relaxed my vaginal entrance, stifling moans. The rising intense pleasure was wrecking my mind. My body heated up like I was drunk.
"Khiik... hik... hiik... ♥"
Embarrassing sounds leaked from between my lips. I tried to hold back, but my gaping mouth wouldn't close, drooling thick saliva with every voice.
"Hoooook... hok... ♥"
Twitch, twitch. My tremors intensified, breathing growing labored. I could feel myself approaching the limit.
"Nooo... haaak... ♥"
It was scary. Terrifying. Pleasure incomparable to anything as a man. I wanted to cross that line into climax, yet the intensity frightened me, making me ease up instinctively.
Pucker, pucker. My pussy entrance fluttered as if chasing pre-orgasmic bliss forever. Pure instinctual motion, beyond my control.
"Eh... uht...?!"
"Khiik... ♥"
Punishing my resistance, the tentacle mass swelled and vibrated. Like a warm water balloon sloshing inside my pussy.
"Hoooook...! Kkok...! Okk..."
I couldn't hold out. No, I couldn't hold out ♥
"Hooooook... ♥"
Finally, I let out an unbelievably vulgar cry and reached climax. Face-down on the floor, I stretched my legs straight and convulsed.
"Haaak... heeek... hek..."
It wasn't just one climax. My body shuddered on its own, savoring the lingering afterglow.
"D-Don't... knooow..."
Fireworks burst in my head with a bang!, my vision whiting out before focus slowly returned. A terrifying phenomenon I never wanted to experience again... but on the other hand, an ecstatic climax I yearned to feel once more... ♥
