Chapter 15 – Akari’s Mask and the Secret of Infinite Energy

The rest of the classes passed in a hazy, dazed blur.

Concentrating on the teacher was the best I could manage. My mind was trapped in that corner behind the building—the feel of Akari’s slick heat, the way her love juices trickled down her thighs every time I thrust deep and fast inside her.

Every time I closed my eyes, I could feel her inner walls clenching around me, her muffled moans vibrating against my hand.

Akari’s classroom (on the third floor, an advanced class) was far from calm.

One of her close friends—Yumi, the long-black-haired sports-club girl who was always glued to her side and loved gossip—approached her during the break between periods. She narrowed her eyes with a curious grin.

“Hey, Akari… what’s up with you today? You’ve been acting weird since lunch. I saw you running off with that first-year boy… Suzuki or whatever… and when you came back, your face was flushed, and your legs were shaking. Did he do something to you? Or what?”

Akari lifted her face from her book and instantly slipped back into her cool, calculating demeanor.

She elegantly crossed her legs, smoothed her skirt, and answered in a perfectly calm voice as if nothing had happened.

“It’s nothing, Yumi.

He just wanted advice about gym class.

It wasn’t a big deal.”

Yumi frowned and glanced down, noticing the small wet spot on the inside of Akari’s skirt along her thigh.

She pointed discreetly.

“What’s that?

There’s a stain… what happened?

Did you spill something?”

Akari felt the heat rising in her neck, but her expression didn’t change.

In her mind, she remembered clearly how my cum had mixed with her love juices and dripped out of her after I pulled out.

Yet her voice stayed firm, delivering the perfect lie.

“Oh, that… I got a little wet in the bathroom by accident.

The faucet was broken and water sprayed everywhere.

It’s nothing.”

Yumi gave her one more suspicious look, then finally shrugged.

“Weird… but if you say so.

Still, you’re acting pretty strange.

If that kid’s bothering you, just tell me. I’ll handle it, okay?”

Akari gave a cold smile, but inside her heart was pounding at the thought of me.

“Don’t worry.

I’m fine.”

When the last class ended, Lustara was floating beside me. Invisible to everyone else.

I walked down the hallway. My body was still sensitive, and there was a faint, pleasant ache between my legs.

But the strangest part was that I didn’t feel tired at all.

If anything, I was overflowing with more energy than I had ever felt before.

It was like I could do the same thing ten times in a row and never get worn out.

Lustara chuckled softly and pressed herself against my back, rubbing her chest into me.

“You noticed, right?♡ ‘How am I not exhausted after sex that intense?’ That’s what you’re thinking, isn’t it?

Yes, Haruto-kun—that’s one of the gifts I gave you.

Infinite sexual energy.

You’ll never have to worry about sex fatigue again.

You can have as much sex as you want, as many times as you want, without putting any strain on your body.

No tiredness, no pain, no exhaustion.

And your cum… regenerates instantly.

You can keep satisfying girl after girl without ever running dry.

It’s a present from the goddess of love and sex. Eternal pleasure. No limits, no side effects.”

I stopped dead in the middle of the hallway, mouth slightly open.

“Seriously?

If I wanted to… I could do it all day long?”

Lustara laughed. That husky, playful voice floated right in front of my eyes and danced through the air.

“All day, all night, every single day.

No marriage needed, no physical pain, and your seed will never run out.

You’re the one I chose… and I’ve freed you from sexual burnout.

Just imagine it. Akari, Aoi, Misaki… a harem you can fuck one after another, nonstop, for as long as you want.

Doesn’t that sound perfect?”♡

A shiver of pleasure ran down my spine.

The thought was overwhelming… and incredibly arousing.

I glanced down the hallway that led to the area where Akari’s classroom was.

Right then, she walked out with her group of friends, but the moment our eyes met… her face instantly flushed red.

She bit her lip and looked down, her steps turning a little unsteady as if she could still feel my cock deep inside her.

Lustara whispered in my ear.

“Look at her… she can still feel your cum inside her.

She wants more.

You gonna call her this afternoon?

Or, now that you know you can go round after round without getting tired, do you want to try it with Aoi instead?”

I smiled. I could feel raw power racing through my veins.

It was different from before.

And this… was only the beginning.

Chapter 16 – Messages, Doubts, and the Goddess Who Watches

The after-school chime rang out as usual, and the afternoon sun beat mercilessly down on the suburban school building.

The humid air is typical of a Japanese summer. The scent of heated asphalt mixed with the soft fragrance of late-blooming cherry blossoms drifted across the schoolyard.

I slung my bag over my shoulder and left the classroom. The pleasure from earlier still lingered inside my body.

Akane’s hot, wet tightness, the muffled moans pressed against my shoulder, and the way her depths squeezed me tight every time I thrust inside her….

Thanks to Lustara’s power, my body wasn’t tired at all. If anything, I felt so full of energy that I could probably go ten more rounds without breaking a sweat.

My phone vibrated in my pocket.

A LINE notification. From an unknown number (but I knew exactly who it was).

Akane:

Sensei… Class is over.

Right now I’m in the third-floor girls’ bathroom near the rhythm gymnastics club room by the gym.

After club, when I changed, I put on my underwear… the sluttiest pair I own.

Black lace, with a hole right in the middle….

I bought them because I wanted you to see them… and touch them.

Just imagining it has me throbbing already….

Please… come.

I want you inside me again.

I love you so much it hurts in my chest♡

Inside my uniform pants, my cock instantly went rock-hard.

I glanced around. The hallway was almost empty—only a few students heading to club activities were disappearing down the distant stairs.

Lustara floated beside me, her purple eyes sparkling.

“Fufu♡ Your new favorite little slave is so honest and obedient.

Crotchless panties… she really wants you to slide right in, doesn’t she?”

“Hang in there, Haruto.

The third-floor girls’ bathroom is empty right now.

The club has already started, so no one’s coming.

…And even if someone does show up, you can handle it however you want, right?”

My heart hammered hard. I dashed up the stairs.

I quietly opened the door to the girls’ bathroom.

Akane was the only one inside.

She stood in front of the large mirror, skirt hiked all the way up to her waist, and blouse unbuttoned down to her navel.

The black lace panties were exactly as lewd as she had described.

The sides were sheer, and the bold slit in the center clearly showed her swollen, glistening pink pussy.

Love juices had already trickled down her thighs, leaving shiny trails.

The moment she noticed me, Akane spun around and dropped to her knees. She placed both hands on my thighs and looked up at me with worshipful eyes.

“Master… thank you for coming….

Look… I wore this entire outfit just for you.

I wanted you to understand that I belong completely to you….

Please… make me yours again… I love you so much…”

I gently lifted her and pressed her against the cold tiled wall.

I ran my lips along her neck, breathing in the scent of cherry-blossom soap, the sweat from club practice, and the thick aroma of her desire.

My hands gripped her toned waist and slowly stroked the curve of her hips.

When I slid a finger through the opening in her panties, I felt scorching, slippery heat.

Her folds were already puffy and slick, love juices clinging to my fingers in sticky strands.

“Ah… mnh… right there… it feels so good… touch me more…”

I sank two fingers in slowly. Her inner walls twitched and clenched, eagerly welcoming me.

Thanks to all the love juices, lewd, sloppy wet sounds echoed through the bathroom.

Akane bit her lip, trying to hold back her voice, but her hips rocked back and forth on their own, begging for more.

“Haah… mnh… I love you… deeper… I want it deeper…”

I unzipped my pants and pulled out my painfully hard cock.

I pressed the tip against her dripping slit, coating it thoroughly with her love juices, then slowly pushed my hips forward.

Schlup… Her hot, fleshy folds enveloped me completely.

When I buried myself to the hilt, Akane let out a long, trembling sigh and dug her nails into my shoulders.

“Master… it’s all the way in… move… please…”

At first, I pulled out slowly, then thrust deep again, savoring every ridge inside her.

Love juices ran down my balls, forming a small puddle on the floor.

I gradually picked up speed, fucking her hard but keeping the noise under control.

The obscene, wet squelching mixed with her muffled moans.

“I love you… harder… fill me up… I love you… I love you so much… I really, really love you…”

Lustara floated right beside us, lazily tracing her own pussy beneath her transparent veil.

Her eyes narrowed, and a sweet sigh escaped her.

“What an amazing view…♡

Look at her losing her mind… she’s completely fallen….

More, Haruto. Fuck her even harder until she cums her brains out….

Just watching you is driving me crazy too…”

I slammed my hips faster.

Akane’s whole body shook violently; her legs had gone limp.

Only the wall and my hands kept her upright.

Her chest heaved, and her hard nipples rubbed against my chest through her shirt.

Suddenly, her inner walls clamped down tight, and a hot gush of her juices sprayed out.

It soaked me even more, splashing loudly onto the floor.

“I love you… I’m cumming… I’m cumming for you, Master!”

I drove all the way to her deepest spot and unloaded thick, hot cum inside her.

When I pulled out, a creamy mixture of my cum and her love juices oozed down her thighs, staining her lace panties and the floor.

Akane dropped to her knees again, gently took my cock into her mouth, and carefully sucked out every last drop.

Her eyes were wet with tears as she gazed up at me lovingly.

“I love you… thank you… that was the best… I’ll always love you…”

While she wiped herself with tissues and straightened her skirt, Lustara drifted closer.

She was still touching herself, cheeks flushed, breathing hard.

“Wow… that was intense♡

Seeing you go that wild almost pushed me over the edge too…”

She smiled sweetly, hands still unconsciously roaming over her own body.

“I feel it the same way.

All of my pleasure belongs to you, too.

Someday… I might let you join in.

I’ll show you me masturbating while I think of you… let you touch…

You decide when, Haruto.”

We left the bathroom separately.

Akane went first, legs still trembling slightly, but walking as if nothing had happened.

When I reached the bottom of the stairs, Yumi was standing at the end of the hallway.

She held her phone, staring suspiciously toward the girls’ bathroom.

She had seen Akane come out with flushed cheeks, wrinkled skirt, and fresh wet streaks on her thighs—

The ultimate gossip lover. She was definitely going to start investigating.

I planned to have her tail Akane, ask around with the other club members, and notice every little oddity.

The secret was in danger… but there was still no decisive proof.

With Lustara floating beside me, I headed for the station while quietly touching my own body.

“Akane’s probably going to message me again tonight…♡

Yumi… she’ll start sniffing around soon.”

“Should we pull her into the game, too?

Or… focus on Aoi during tomorrow’s classes?”

I gave a small smile.

A hot thrill spread through my body.

This pleasure was still far from over.
