Chapter 34

Fresh from a quick shower, I was led by Akane, the maid, to Ayaka-san’s room for some long-overdue intimacy.

(Just thinking about it’s got me hard…)

Ayaka-san’s stunning face, silky hair, curvaceous figure, and those milk-spraying oppai. Plus, our child growing in her belly. Wanting to see her, to make love to her—it’s only natural for a healthy guy to feel this way.

(But going too hard might affect the baby. Guess I’ll use that…)

I slipped my hand into my bathrobe pocket, confirming the small vial of liquid was there.

“Here’s the room, my lady,” Akane announced.

“Thanks, Akane-san.”

“Y-Yes!”

I thanked her, catching her slightly flustered expression.

Knock knock.

“My lady, Master is here.”

“Please, come in.”

Passing through the door Akane opened, I entered a dimly lit room with a large bed.

“Darling…♡”

“Ayaka…!”

The moment I saw her, all my pent-up longing exploded, and I craved her intensely.

(I need to feel her skin…!)

I threw open my bathrobe and pulled her into my arms.

“Ayaka! —Haa, haa…”

“Haan♡ So sudden… So passionate…♡”

Forgetting to close the door, I pressed my throbbing penis against her, burying my face in her neck.

“W-W-Wah…!”

I’d forgotten Akane was right behind us.

But there was no time to care—Ayaka and I locked lips, diving into a deep, fervent kiss.

“Chu…♡ Darling…♡ I can’t wait anymore…”

“Me neither… I’m at my limit.”

My lower half was buzzing with excitement, precum already leaking from the tip.

“Ah… Aa♡ Your penis… It’s so big…♡”

Ayaka’s hand wrapped around my swollen cock, her smooth, flawless fingers coiling around the shaft.

Her cheeks flushed, she leaned closer, studying the naughty fluid oozing from my slit.

“It’s pulsing… So hot, so hard… Ah…”

My cock twitched, spurting more precum that stained the floor.

“Ayaka… I can’t hold back anymore…”

My cock ached, my balls taut—I was desperate for her, nearly losing my mind. Seeing my urgency, Ayaka slipped off her underwear, giving me a dreamy smile.

“Embrace me! Make it unforgettable for a lifetime…♡”

“~~~… Aa!! Here I go!”

I scooped her up in a princess carry, gently laying her on the bed.

“An♡ Darling… Hurry, put it in…♡”

The moment she hit the bed, she begged for my cock. Looking closer, I noticed her pussy dripping with slick, earnest juices.

“Aa! I can’t wait another second! Here…!!”

Zubu… Nurururu♡

My engorged cock slid into her exquisite pussy. The flared glans parted her slick folds, the veined shaft stretching her passage.

“Aan♡ So… big…!”

“You okay?”

“Yes, because it’s yours, it feels so good…♡”

True to her words, her vagina clenched my cock kyunkyun♡, welcoming me.

Nyurururu♡ Kotsun♡

“Aa… Aaa…♡ It’s in…♡”

My sizable cock reached her depths, nudging her cervix. The sensation alone seemed to push her to a light climax, her body trembling with pleasure.

“Aa, aa… It’s… again… Nnn♡”

Pyu♡ Toro…♡

“Milk… Gulp… Sweet…”

“Y… N-No… —Nuu♡ Don’t squeeze…♡”

Momi♡ Munyu♡

Unable to resist her milk-dripping oppai, I latched on, drinking the sweet liquid. Savoring their supreme softness, I used my ability to heighten her sensitivity.

Chuuuu♡

Sweet, like diluted milk with a hint of sugar. Knowing it came from her body fueled my arousal.

(I want her to feel even better…)

My cock’s larger than average, and thrusting hard might jolt the baby in her womb.

(Oh, right. I’ve got that…)

“Ayaka, I’m gonna apply some oil, okay?”

“Haa… Haa…♡ Yes…”

With her consent, I opened the vial and poured white oil—pao fruit oil from Waheide—onto her cleavage.

“I’ll spread it… Here, here…!”

“Nn♡ Aa…♡ Sweet scent… And my chest… feels hot♡”

“Here! Here!!”

Gunyuu♡ Munyumunyu♡ Gyu, nyurun♡

My hands moved like soft creatures, circling and kneading her pliant breasts.

“Ii! Hyaa…♡ No, no… This is too much…♡”

“You’re adorable, Ayaka… The perfect woman… Here!”

“Hii, hiiiin♡ No… I’m cumming… Aaaa~~~♡♡♡”

Pushi♡ — Pyuuu♡

As I gripped her most sensitive spot, milk shot forcefully from her nipples.

“An♡ Aa♡ Aa~~~♡ No… My oppai are leaking…♡ I’m cumming… Cumming~~~♡”

Her oppai gushed thick milk like a tank.

Gyu♡ — Pushuu♡

“Hahiii♡ Cumming… Cumming… Aaaa~~~♡♡♡”

“Incredible… You’re incredible, Ayaka… Haa… Haa…”

Just my hands made her writhe, climaxing as milk sprayed.

(Amazing, amazing, amazing! This is a mother’s oppai… My woman’s oppai…!)

A surge of conquest overwhelmed me. Boiling desire consumed me, leaving only thoughts of Ayaka.

I got her pregnant, changed her body—a goddess-like beauty, the ultimate woman.

“Ayaka… I love you. I’m the luckiest man alive…”

I whispered my love into her ear, raw and unfiltered.

…

<Ayaka’s Perspective>

“Aa…! I’m cumming… Cumming…♡ Haaa~~~n♡”

Once again, an unseemly cry slipped from my lips. But I couldn’t help it.

The man before me—

“Ayaka… I love you. I’m the luckiest man alive…”

He’s so kind, earnest, with a rugged, handsome body.

…

This boy saved my life, giving me a new beginning. Despite his youth, he worked tirelessly, growing into a remarkable man.

His dedication made my heart flutter daily. But an unexpected crisis kept us apart for a month.

“Come back soon… darling…”

Loneliness sometimes overwhelmed me. Yet, what soothed those days was the child in my womb—his child.

“You want to meet your father too, don’t you? …Hehe.”

As if answering, the baby moved. Counting the days, grateful for the feminine joy I’d once given up, I awaited him.

On the thirtieth day, we finally reunited.

“I’m home, Ayaka.”

In just a month, he’d blossomed from a bud into a striking man, captivating everyone. Two heads taller, broad shoulders, a thick chest, and muscular arms—yet lean, not an ounce of fat.

Kyun…♥

I already loved him, but it was like falling in love at first sight—silly as that sounds. My womanly heart chose him as my lifelong partner.

“Is it cold?”

His voice, clear and gentle, resonated in my ears with a masculine baritone.

“Can I see your face? It’s been a while.”

He stood before me, our eyes meeting.

Jun…♥

A jolt like lightning coursed through me.

His once-youthful face had matured into that of a stunning man.

The lightning traveled down my spine, pooling in my lower half, wetting my womanhood.

I fell for him again—no, I was utterly captivated. I’d do anything to be loved by him—body, heart, soul, even the Saionji family. I’d give it all.

In that moment, I became his completely.

…

Gyu♡ — Pushuu♡

“Aan♡ Cumming… Cumming… Cumming~~~♡”

Each time his hands kneaded my breasts, waves of unimaginable pleasure surged from deep within, gathering at my nipples.

Pushuu♡

“Auu♡ C-Cumming… Ahiii♡”

Pleasure melted my body. Pregnant with his child, penetrated by his penis, my oppai milked—no woman could stay sane through this.

“I love you… I love you, darling…♡”

I couldn’t think straight. The pleasure overwhelmed me, words escaping without coherence.

“Love… Everything… Everything…♡”

My thoughts spilled out as disjointed words. He must be confused, unable to understand.

But then—

“Ayaka! I want all of you!!”

He understood everything.

“Oh…♡ Oohhh♡ Nnnu~~~♡♡♡”

In that instant, something burst inside me, and I was swallowed by pleasure.

※

Ayaka let out a cry I’d never heard before—she came.

“Ooh… Hohhh♡”

Her goddess-like face twisted in ecstasy, drool dripping from her mouth. The refined heiress of a prestigious family, a lofty flower from a world apart, was—

Pushuuu♡

“Cumming… Uuu~~~♡”

Squirting milk while moaning lewdly. Seeing that, my body ignited, an overwhelming wave of pleasure crashing over me.

Dobyuuu♡

My love for Ayaka overflowed, erupting as semen.

“Agu! My cock… It’s cumming on its own!!”

Without thrusting once, her love and her pussy’s grip alone made me cum.

Dobyu♡ Dobyu♡ Dobyu♡ Dobyu♡

“Auu♡ Hiii… Iiii♡”

Matching my ejaculation, she climaxed and squirted milk repeatedly. Her overwhelming preciousness made me—

“Ayaka… Jurururu!”

“Oon♡ Jururu… Juzuzu♡ Rerurero… Jupa♡”
