Third Period, Tutoring, and Cinderella. Oh Shit.

My hand holding Lee Suyeon's phone trembled uncontrollably. Even though I hadn't been caught yet, the first thought that slammed into me was that I was completely fucked. My lower abdomen throbbed with sharp pain. Fuck, is someone watching? Does she have a hidden camera?

I scanned the room, but nothing resembling a home cam caught my eye.

"Why are you like that...? Whose call is it?"

"Uh... well...."

When I turned the screen toward Lee Suyeon, her face filled with shock too.

"!!!"

"What should we do?"

"......Just... just leave it, please."

Lee Suyeon squeezed her eyes shut and turned her head away. She looked like she wanted to escape this reality entirely.

I was about to set the phone down when a thought suddenly flashed through my mind. That scene I had seen so many times in porn. At the same moment, my hand moved on its own.

"!?!!?"

I had pressed the call button and switched it to speaker. At her husband's deep, resonant voice, Lee Suyeon's eyes flew wide open as she stared at me.

"Suyeon?"

What are you doing? Answer him. I mouthed the words and signaled urgently with my eyes.

After a moment of hesitation, Lee Suyeon turned toward the phone and spoke.

"Um, I was taking a little nap."

"Did I wake you? Sorry."

"No. What about you, honey? Are you done with work?"

"Yeah, I just got to the hotel, showered, and lay down."

I placed the phone beside Lee Suyeon and slid back down between her legs. I spread her tightly closed thighs wide open.

"Really? You've worked ha— Heut?!"

"Huh? Suyeon?"

Lee Suyeon glared at me. Her eyes screamed What the hell are you doing?

But how could I possibly hold back in a situation like this? Sure, the tension made my stomach hurt, but lust overpowered everything. The thought that I might never taste this again made my body move first.

Just as Lee Suyeon had taught me earlier, I pressed my glans against her pussy. That alone made her gasp and hold her breath. She clamped a hand over her mouth and glared at me like she wanted to kill me.

"Suyeon??"

"Uh-huh, I just yawned a little.... Sorry, honey. I'm especially tired today... ah... ngh...."

"Was work tough today?"

"Uh, y-yeah... ngh... The students... they ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠wouldn't... listen...."

"Who? That Jihun bastard again? Did he try to peek up your skirt and at your cleavage again today? Want me to call and scold him?"

"Ah, nooo... It's a new student... ngh, his academic enthusiasm... is just... so exceptional...."

"Really? Then isn't that a good thing?"

"It is... but ngh...."

"But what? ...Suyeon?"

"Ah, it's nothing... ngh...."

"......Suyeon, are you crying? Are you crying right now?"

"Ah, no.... heut...."

"Switch to video call."

"H-honey... I just woke up... ngh... my face is...."

"It's okay. Switch it. Hurry."

With no other choice, Lee Suyeon moved to switch to video call—then simply hung up instead.

"Sunghyuk-ssi, what are you doing...!"

"The situation was too fucking hot, I couldn't resist...."

"What if we get caught... I can't do this to my husband...."

"I'm sorry. I won't do it again."

A video call came through immediately. I quietly slipped off the bed and left the room. While she talked with her husband, I stayed in the living room, idly stroking my cock. To soothe my frustration, I stared at the clothes and bra Lee Suyeon had discarded earlier.

The call is dragging on.

Since it was on speaker, I could hear their conversation clearly from the living room. Her husband kept worrying about her, and she kept reassuring him that she was fine.

"How was your day, honey?"

"Same as usual for me. The magic stone deposit from this gate is enormous, so it looks like it'll take a little longer."

"Hmph. You said you'd come back soon...."

"Sorry. A new gate suddenly appeared right next to it. What could I do?"

"I'm so lonely... I miss you, honey...."

"Just hold on a little longer, okay?"

"...Alright."

They really were a loving couple. I'd just fucked the wife of such a devoted husband, and the moment the call ended, I was going to fuck her again.

...Should I use it in advance?

I debated whether to activate Stamina Recovery now. I figured I could probably cum once more, but No Questions Asked! only had about twenty-two hours left. Considering the cooldown, using it now would let me cast it again before the charm expired tomorrow.

Yeah. Let's use it. Better to get the cooldown started.

The fatigue that had been crushing my body vanished in an instant.

Whoa.

This was incredible. I'd lived with chronic exhaustion for years, yet now I felt absolutely nothing. No tiredness at all.

Lee Suyeon finally came out to the living room after ending the call. She wore the same outfit as before, the torn section of her stockings still streaked with white fluid running down her thighs.

"Um... Could you go home for today, please...?"

She spoke hesitantly, forcing the words out. After making me wait this long, now she wanted me to leave? No chance.

"That won't work. Look, I'm still rock hard."

"Ah......"

"I'm planning to keep going for ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠another twenty-one hours."

"Ah, yes...... I understand."

The anxiety that had filled her eyes melted away, replaced once more by sensual heat. The effect of No Questions Asked! made it impossible for her to refuse my commands.

"Shall we do it right now?"

"Of course."

"Hehe, then we should start third period."

She took my hand and led me back to the bedroom, where we unleashed a storm of sex. That day alone I came four more times. We fell asleep exactly as we were, without even pulling up a blanket.

My phone alarm woke me. Lee Suyeon slept soundly on her stomach beside me, breathing softly.

Waking up to a woman sleeping next to me. This was a first. Didn't that unlock an achievement?

.... Nope.

Still, the way her ass rose so prominently in that prone position was insane. It wasn't a melon. It was a watermelon. A massive Mudeungsan watermelon. Fucking huge.

How could I possibly just look at an ass this tempting? My hand moved first.

I pressed my palm against it. The elastic flesh pushed back against my fingers.

Boing. Boing.

It felt like I could bounce on it like a trampoline. I was enjoying the sensation when Lee Suyeon stirred awake.

"Mmm...... Sunghyuk-ssi? What are you doing...?"

"Oh, it's because Teacher Suyeon's ass is so beautiful."

Squeeze, squeeze—

"...Why are men always so desperate to touch breasts and asses?"

"Not touching Teacher Suyeon's ass would be a crime."

"What are you talking about?"

"Otherwise I'd have to be gay."

"...??"

Squeeze, squeeze— Lee Suyeon didn't seem to mind my hands and simply lay there quietly.

Ah, I can't hold back anymore.

I was about to bury my face in that perfect ass when I noticed the dried white crust around her pussy and stopped.

...It would probably smell awful.

My own cock was in the same state. It reeked.

...Time to wash up.

"I'll shower first."

"Okay."

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

After showering I lay on the bed and waited. About an hour later Lee Suyeon emerged, completely naked. She pulled out fresh underwear and began to dress. Sexy black lingerie with delicate lace. Given the size of her ass, the rear coverage on the panties was enormous.

Wow....

My cock, barely awake, began to rise again.

Lee Suyeon slipped on a loose, long dress.

"Will you have breakfast?"

"Will you make it for me?"

"Of course."

"Good. But I have one request...."

"What is it?"

"Could you wear nothing but an apron?"

"......Yes."

Lee Suyeon began removing the clothes she had just put on. Rustle. Rustle. I followed the now completely naked woman into the kitchen. Her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠bare ass swayed with every step, incredibly arousing.

She opened a drawer, took out an apron, and put it on. I sat at the dining table and simply admired the view from behind.

Chop chop chop— Bubble bubble—

Watching her voluptuous ass jiggle while she cooked, she soon prepared a full feast. It was far too much for breakfast. The large table was completely covered with dishes.

Gurgle—

Come to think of it, I hadn't eaten dinner yesterday and had simply fucked nonstop. My stomach finally protested loudly.

"Wow, do you always prepare such a huge spread?"

"No, I usually eat simply. But we have a guest today."

"So you made all this for me?"

"Yes. Please eat."

It was the first time I'd ever received such generous hospitality.

"Mmm! Delicious!"

"Hehe, I was worried, but I'm glad."

"You're an amazing cook, Teacher Suyeon."

"Eat as much as you want."

"Um, could you feed me?"

"What a demanding student. Here, ah~."

She even obeyed commands like that.

Indirectly experiencing newlywed life with a married woman. Was there an achievement for that?

...Nope.

After filling my stomach with the home-cooked meal a married woman had prepared, my eyes were drawn to her body again. As she carried the dishes to the sink, Lee Suyeon noticed my raging erection and let out a small laugh.

"So energetic from the morning."

"It's all because of you, Teacher Suyeon."

"Why?"

"How could I not get hard when such a sexy body is standing naked right in front of me?"

"You say such embarrassing things so casually."

"I learned it from you yesterday."

"When did I ever say— heuk?!"

I set the bowl down and grabbed her ass. My fingers sank into both her cheeks and her pussy lips. Lee Suyeon jolted in surprise.

"Hyaat...."

"There's still some left inside. My cum."

"Y-yes... Even after I washed... it didn't all come out... You came so much yesterday... ahh!"

"I'll refill you."

And so, from morning until evening, we kept rolling around on Lee Suyeon and her husband's bed. The moment Stamina Recovery's cooldown ended, I used it again and thrust mercilessly into her exhausted, sobbing pussy.

Tick. Tick. Tick. Tick. Tick—

The pink notification window floating above her head vanished.

Her face, which had been gazing at me with seductive, loving eyes, changed in an instant. The expression drenched in ecstasy twisted violently.

"A, a, aaaaaaaaaaagh—!!"
