=======================

"Aahhn! Daddy! It's so good! Your cock is amazing!!"

Aika's moans echoed through the room.

Her voice was bolder than usual—probably not just my imagination.

"Aika… You're tighter than usual…"

I took her from behind as she braced herself against the kitchen counter, but the grip around my cock was stronger than normal.

As I slammed into her, Aika glanced back at me, looking more aroused than ever.

It must have been because of the other presence in the room.

"Aika? Does it feel good… getting fucked from behind?"

Mizuki, kneeling on the tatami, watched us with hungry eyes.

Having someone else observe us while we had sex added a whole new layer of depravity.

"It feels so good! Daddy's cock… it reaches so deep… I'm gonna cum soon!"

Hearing her describe my cock to a third person mid-act was both embarrassing and thrilling.

Aika seemed to feel the same—every time she explained our sex to Mizuki, her tight little pussy clenched around me even harder.

"Umm… Can I join in too?"

"No! I told you to just sit there and watch, didn't I?! Aahhn! Daddy, no! I'm gonna cum again!!"

Even as she scolded Mizuki, Aika was lost in the pleasure.

At first, she might've been aware of Mizuki watching, but the closer she got to orgasm, the more everything else faded away.

The power of sex was truly overwhelming.

"Aika! I'm gonna cum inside you!"

"Please! Fill me up! Pump your cum deep inside me, Daddy!!"

The moment she begged for it, an intense wave of pleasure crashed over me.

At its peak, I came inside her.

"I'm cumming! I'm—CUMMING!!"

Her pussy clenched down hard as my semen flooded her womb.

I could feel it hitting her cervix.

The sensation of creampieing her never got old—especially knowing she was just a 13-year-old middle schooler, and my stepdaughter on top of that.

And now, with another girl her age watching…

The depravity was on another level.

"Daddy's cum… it's so much… My mind's going blank…"

Still connected to me, Aika panted heavily.

This was already the third time I'd creampied her tonight.

Her legs trembled, and my cum dripped from her stretched-out pussy.

"It does look amazing…"

Mizuki gulped, clearly entranced.

She'd been ordered to just watch, nothing more.

No touching, no sucking—just observing.

"Hey, can I finally—"

"No way! You're just here to watch me and Daddy have sex!"

That phrase—me and Daddy's sex—was so sinful, it made my cock twitch back to life.

"Come on, Daddy… Empty your balls inside me…"

Her dirty begging made me fully hard again in an instant.

Aika's depraved whispers were more potent than any aphrodisiac.

"Ah! Ah—!"

The first moan was from my cock swelling inside her.

The second was when my tip hit her cervix.

Aika's body was so honest—it made fucking her even more satisfying.

I knew her inside and out by now.

How many times had I creampied her at this point?

"Daddy… Does my pussy feel good…?"

"It's the best… No one else could ever feel this good…!"

I'd only ever been with Aika, but I was sure it was true.

No other girl—no matter how beautiful—could compare.

This was the peak of pleasure.

"Aika's so unfair! I wanna have sex with him too! I wanna get fucked from behind and filled up with cum!"

Mizuki stood up, unable to take it anymore.

I never expected another middle schooler to crave sex with me.

"No! Mizuki, you're just here to watch!"

Aika moaned the words between thrusts.

This was her revenge—making Mizuki suffer just like she had earlier.

She'd never intended to let Mizuki join.

"If you're that desperate… Use the toy in the cupboard! That dildo's big enough to reach your womb!"

It was the same vibrator Aika used when I wasn't around—thick, ribbed, and powerful.

"I don't want a toy! I want his real cock!"

"No! Daddy's cock is mine!"

As if to prove it, Aika clenched down hard.

I rammed into her even deeper, claiming her just as fiercely.

"Daddy… I love you…!"

"I love you too, Aika…"

Our deep kiss shut out everything else.

Like Mizuki didn't even exist.

This was what Aika had wanted all along.

But she'd underestimated Mizuki's determination.

"If that's how it is… I'll just force my way in."

The next moment, I felt new sensations on my back and between my legs.

"Huh?"

Aika, still being fucked from behind, didn't notice.

But I sure did.

Because Mizuki had just grabbed my cock.

"Men are so defenseless from behind during sex…"

When I turned, Mizuki's perfect face was right there.

Her lips sealed over mine.

"—Mmph!"

Her tongue invaded my mouth, slick and relentless.

A completely different kind of kiss from Aika's.

At the same time, her right hand stroked the base of my shaft—the part not buried inside Aika.

Her left hand found my nipple, sending electric jolts through me.

"Ngh…!"

I barely held back from cumming right then.

Half my cock was in Aika's pussy, the other half in Mizuki's grip.

My mouth was full of Mizuki's tongue, and my nipple was between her fingers.

I'd thought sex with Aika was the ultimate pleasure.

That nothing could top it.

But now, with Mizuki adding her own stimulation?

"Your cock's twitching so much… You're getting off on me touching you, aren't you?"

Her left hand kept playing with my nipple while her right slid lower—cupping my balls, then brushing against my asshole.

This was a first.

Even Aika had never done this.

"You really are a pervert… Letting a middle schooler touch your nipples and ass…"

I wanted to argue—she was the one doing it—but I was too close to cumming to speak.

"Touching you is making me wet… Hey, you know what? Track girls don't wear anything under their uniforms. Some wear sports bras or shorts, but I just go commando."

As she whispered in my ear, Mizuki pressed her chest against my back.

Soft, bare mounds—completely different from Aika's.

Just a thin layer of fabric between us.

The kind of supple, bouncy tits only a 13-year-old could have.

Wasted on a middle schooler.

"It's okay, Daddy. Give Aika your last load tonight…"

Aika loved swallowing my cum—she practically demanded it every morning.

With her begging like this, I had no choice but to give in.

"Hey! I'm the one who got him hard again!"

Mizuki insisted she deserved some of it.

"No. You promised to obey me!"

"That was before!"

"Then your promise means nothing!"

Their argument quickly turned into a competition—who could pleasure me better?

Double titfuck.

Double blowjob.

"Daddy… You like my tits and mouth more, right?"

"That's not true, is it? Your cock gets harder with me…"

Honestly? Both were heaven.

Two gorgeous middle schoolers licking my tip, pressing their soft tits against me—this was paradise.

And soon, I reached my limit—

"Kyah!"

"Wow… It's still coming out…!"

I painted both their faces, tits, and mouths with the biggest load of the night.

Fully aware of how wrong this was…

I still thanked whatever god had allowed it to happen.

This was, without a doubt, the best orgasm of my life.
