How Using My Oppai Skill to Enlarge My Sister’s Breasts Led to Building a Harem - Chapter 51.3

Chapter 51.3

As agreed, I, the victor, am set to ravage Shishidou Kokoro. It’s consensual, her agreement secured beforehand.

“(Here we go, Shishidou-san.)”

“No, too big… Aaa~~~!?”

Whispering the start of the sex show in her ear, I raise my hips for the cameras, flaunting the moment of insertion.

My glans and corona tease her entrance, feeling her wetness build. I lean in, letting my tip sink deeper.

Zunyuu~~~♡

“Naa…!! No, it’s… going in…”

(Uoo… So tight!)

As my glans slides in, Shishidou-san’s pussy clamps down with unbelievable force.

(Her trained body… Feels insane!)

The grip’s unlike any normal woman’s, a testament to her sculpted physique, proof of her strength.

(This is… the best. Fucking a woman this incredible…)

Not just looks—her inner strength makes her the ultimate woman. A pussy I might never taste again.

The thought alone surges power into my cock, swelling it further.

“Stop, I said…! Aa…”

Pinning her resisting shoulders, I force my cock deeper.

“No, nooo~~~!!!”

No matter her training, raw strength favors me. She struggles, flailing to push me off.

“Hey! Stop… you!!”

But with her shoulders held, all she can do is pound my hard abs and thick pecs.

Zuchun♡ Paan! Paan! Paan! Paan!

“Aa…! Stop, don’t thrust inside…!”

“…”

Ignoring her feeble strikes, I fuck her pussy with my rock-hard cock. The lewd panpan of flesh echoes in the hushed arena, amplifying the scene’s abnormality.

(She’s perfect…)

“Stop, you rapist…! Aa…”

Feigning resistance, Shishidou-san subtly lifts her hips, angling for my thrusts.

Paan! Paan! Paan! Paan!

“Yah… Aa, I’m… losing it…”

“Fu… Fu…”

My relentless pounding and rubbing inside her vagina add a sultry edge to her voice. Sensing her arousal, I slide her bikini up, grabbing her exposed, snowy breasts.

“Hyan♡ W-What… are you doing!?”

Her oppai bared, she protests. But I don’t care, roughly kneading her flesh.

Gunii♡ Gunyu♡ Gyuu~~~!!

“Hii♡ Stop, yah… Aan♡”

Her soft, white breasts twist and deform under my hands.

(Insane… Her abs are so chiseled, yet…)

Her oppai are as soft as mochi. The contrast—tight abs, jiggling breasts—feels like art.

Gunii♡ Gunii♡ Gunii♡

“No way… I don’t want this… Haan~~~♡”

Her body trembles, hitting some limit, a clear sign she’s embracing pleasure. A sweet pheromone scent wafts from her.

(So beautiful… A sculpted, flawless beauty…)

Her form drives me wild—

“Nnn!? An, no kissing…”

Shaking her head, I claim her lips, savoring her meltingly sweet saliva.

“Nn~~~! Haa… Nn, stop…”

Thrusting my tongue into her mouth, I lick her palate and gums, sucking her startled, retreating tongue.

Rerorero♡ Zuzuzu…♡

I tease her with lover-level kisses, toying with her seemingly inexperienced mouth.

“Don’t… suck so much…♡”

Savoring her lips, I ravage her breasts and pound her pussy.

In front of the cameras, shamelessly devouring the ultimate beauty.

“Aa… I’m… having sex…”

I…?

Her tone shifts. From defiant to a normal woman’s voice.

Maybe this is her true self.

“I admit it… You beat me.”

She grabs my hand, intertwining our fingers.

(She’s ready. Let’s go!)

Reading her cue, I grip her hand, hammering my hips in missionary with ferocious speed.

<Shishidou Kokoro’s Perspective>

Paan♡ Paan♡ Paan♡ Paan♡

The masked man—no, boy—holding my hand starts thrusting.

“Nn♡ Aa… What’s this…♡”

From afar, it’s hard to tell, but up close, he’s clearly much younger.

(Feels… good. Sex is this amazing…♡)

Devoting my life to martial arts, this is my first time. It’s far better than I imagined. Resistance turned to acting—then pleasure.

When this shameless project was pitched, rage consumed me.

It felt like being told I’d failed as a fighter. Women’s pro wrestling is idol-like—new girls debut yearly, replacing those who fade. For a nearly 30 veteran, adult gigs are common.

I’ve pushed my body since school—wrestling, MMA, pro wrestling. It’s battered, barely holding together. At 29, I felt my limits as a fighter and woman.

So I accepted. To end my aimless career. Lose, retire, and close my 20s beautifully.

The condition: a man strong enough to beat me. I’d never let a weakling touch me.

Paan♡ Paan♡ Paan♡ Paan♡

“Nn♡ So good… Nn♡”

His thick, hard cock knocks at my womb. A young male’s tool, craving my nearly expired body.

I had countless chances to win. This kid was a pro wrestling amateur. I held back to keep it going.

Paan! Paan! Paan! Paan! Paan!

His fierce thrusts shake my oppai, lewd moans escaping.

“—Wooo!!”

The crowd roars, warming to the sex show.

“My oppai… my pussy, they’re watching… Aa♡”

“Fuu! Ooo…! Uoo…!!”

Pachun♡ Pachun♡ Pachun♡ Pachun♡

He’s as aroused by my oppai as the crowd, his breaths heavy as my soft breasts jiggle with each thrust. His cute reaction makes my womb kyun♡ with heat.

(My pussy… loves it…♡)

He hits my sweet spot, gongon, spiking my pleasure. My first time, yet we’re in perfect sync.

But this feeling isn’t new. During our match, trading moves, I felt the same rush.

Mix-up—elevating each other. He grasped pro wrestling fast.

(That’s why I fell for him…)

I wanted him to end me, so I went all out. My knees finally gave out.

I’ve nothing left to lose.

“More…♡ Make me feel even better…”

Fall. I’ll fall completely. Burn out here, ending Shishidou Kokoro.

※

Shishidou-san’s demeanor shifts again, like a switch flipped, breaking free.

“Oooo~~~♡ More, pound me more♡”

Ignoring the crowd, she bucks her hips wildly, swallowing my cock to the root.

“Nhoo~~~♡ Cock, so good…!”

She’s all in—pro wrestling, sex, everything at full throttle.

Then—

“Oooo!!!”

“A…!?”

I slip behind, slamming my hips with all my strength.

“Ngo…♡”

My thrust zudon♡ nails her core.

“Aga!? I’m… cumming… Aa, cumming~~~♡”

The pleasure’s so intense, she quakes, climaxing.

Paan♡ Paan♡ Paan♡ —Paan♡

“Ngoo… Cumming… Cumming~~~♡”

(What a lewd voice…!)

Despite the cameras, she lets out filthy moans, squealing like a pig with each thrust.

“Ooo… Hn! Hn! —Hn!!”

Irresistible. Railing a woman this strong.

Making her moan with my cock—it’s pure joy.

This female is mine.

Dochun♡ —Dochu♡ Dochu♡ Dochu♡ …Dochun!!

“Aga♡ Cumming! Going crazy~~~♡”

Like rutting beasts, we fuck wildly before the crowd.

Neither she nor I care about the onlookers anymore, just unleashing our surging desires.

My limit hits.

(Guu… Gonna leak…!)

My brain’s fried, my balls swollen, urging release. I’m cumming!!—With my last shred of sense, I shift to her side for the cameras.

“Guooo!!!”

“Aaa…♡ So… Cock’s swelling…!”

Dochun♡ Dochun♡ —Dochun!!

“Auu~~~♡ Cumming~~~♡”

Lying sideways before the cameras—

Dobyu♡ —Dobyu♡ Dobyu♡ Dobyu♡

I unleash a massive load inside her pussy, syncing with her climax.

Semen rockets through my shaft, blasting toward her womb. The first shot fills her, the next spilling out, blooming white in the air.

“A♡ Hot…♡ This is semen…”

She catches my load at her cervix, stunned by its heat. But I’m just as shocked.

(Guu… So tight~~~!?)

As I cum, her vagina clamps with insane force.

But I’m not backing down.

Like countless women before, I use my power.

Guni♡ Gunii♡ Gunun♡

“Yaa~~~♡ Oppai, no~~~…”

I knead her mochi-soft breasts, driving her wild.

(There, there…!)

Gunyuu~~~♡ Guni, gunii♡

“Yaan♡ Gonna cum~~~!”

Stroking, squeezing, pinching her marshmallow oppai, my fingers dance, tormenting her.

And—

Guju♡ Guju♡ Guju♡ Guju♡

“Haaan♡ My pussy too… So good♡”

I stir her pussy hole with my cock.

“(It’s all on camera…)”

“Hiu…!?”

Grinding my hips lewdly, I whisper in her ear, churning her pussy.

Our mixed fluids make sticky noises, oozing out—spotting the camera’s approach, I ramp up—

Dochu♡ Dochu♡ Dochu♡ Dochu♡ Dochu!!

“Aaaa~~~!? Yah, aa… My pussy’s wrecked~~~♡”

Demon pistons ravage her pussy.

Splashing fluids hit the camera lens—no matter. Our male and female parts mate with fierce slaps.

“Again…! Aaa~~~… Cumming won’t stop~~~♡”

“Hn! Hn! Hn! Hn!!”

Unstoppable. I pound her pussy while cumming.

Showing off to the viewers, I unleash every desire.

“Ngo♡ Cumming… Aa, can’t stop~~~♡”

“Guuu… O!!”

“Ngooo~~~♡” “Guooo!!”

Our beastly roars echo, shaking the arena, stirring the crowd’s hearts with soaring intensity.

“(Now for the finish…)”

“Ngo…♡”

I lift her fallen female body with my chiseled arms, skewering her anus with my cock—zubo♡—to show her precious hole.

“(Greet your fans…)”

“A… Aaa…”

The show demands this finale. For the audience, her most beautiful self—pro wrestler Shishidou Kokoro, inside and out.

I hold her steady, cock in her anus, waiting for her words.

“A… I, Shishidou Kokoro… retire today…♡”

(What…?)

The arena buzzes. Her unexpected retirement stuns everyone.

“My knees are shot, at their limit… So—”

“Gu…!?”

“Shishidou Kokoro ends here today…♡”

Dochun♡ Dochun♡ Dochun♡ Dochun♡

She bucks her hips, anus fucked, as if flaunting to her longtime fans, declaring her end.

Vulgarly, lewdly, shamelessly.

“With my ass… Cumming~~~♡”

To leave no regrets, to vanish completely—

Shishidou Kokoro roars like a beast.

※

Later—

“Ugh… This was okay, right?”

After the match and sex, I return to Rei-san’s locker room.

“W-Well… You won, and we got the footage… Yeah,” she replies.

Her tone’s off. When I press for details…

“Will it… sell?”

Apparently, we overdid it. Mainstream regulations mean overly intense content might not clear.

“Did I mess up?”

“In a way, it’s legendary…”

I wrestled, performed as an actor, and went too far, but oddly, the crew’s not mad—

Shishidou Kokoro—Defeat Rape, Public Full-Force Mating becomes a banned, legendary work, talked about for years.

As an aside, a month later, a mysterious masked rookie wrestler debuts, evoking Shishidou Kokoro’s prime.
