Chapter 12 – Sleeping With Mother-In-Law

'Come to think of it, this is the first time I've been in another woman's room…'

I hadn't even been to Yeonji's room yet, and now the first woman's room I'd ever entered was my mother-in-law's.

To make it even stranger, I hadn't come in through a normal door but through a hidden passage in the wall. It all felt surreal.

'My first experience, my first visit… all with my mother-in-law.'

This wasn't the time to dwell on it, but somehow, I'd ended up in a closer relationship with my mother-in-law than with Yeonji, the woman I was actually going to marry.

A sense of emptiness, deeper than guilt, washed over me as I stepped into her room.

"Still, inviting you to my room so suddenly makes me feel a little embarrassed," my mother-in-law said, standing there completely naked.

"Wow… it looks incredibly well-organized," I replied, trying to focus on the room rather than her.

"Hehe, thank you," she said with a smile.

Unlike my room, hers was filled with carefully chosen items. What surprised me was how spacious it felt despite the furniture—a sofa, a TV table, a dressing table, and a king-size bed. The layout was so well thought out that it didn't feel cramped at all. It was the kind of room you'd expect from a wealthy lady in a movie.

'Come to think of it, it's not just a feeling—it's a fact.'

As the de facto owner of one of the world's top companies, this level of luxury was probably normal for her. It was like living in a scene straight out of a film—except the genre was a 19+ adult drama.

"Well, it's late, so let's sleep together♥," she said, taking my hand and leading me to the bed.

"Y-yes, Mother-in-law…" I stammered, feeling a mix of nerves and confusion.

"Hehehe, you called me a pig earlier, but why are you so nervous now♥?" she teased.

"W-well, I just got carried away by the mood…" I replied, embarrassed.

Looking back, I'd done a lot of things that would normally be considered rude. Of course, it wasn't a problem since my mother-in-law had encouraged it, but as someone with the mindset of an ordinary person, I couldn't help feeling guilty.

"You'll have to keep treating me like that from now on… you need to get used to it, Master♥," she said, her tone playful yet commanding.

"...….Yes, Mother-in-law…" I replied, reluctantly accepting the situation.

It was an SSS-level scenario—treating my mother-in-law as a submissive partner—but with no other options, I decided to go along with it, guilt and all. I lay down on the bed beside her.

'This is amazing…'

The bed was soft yet supportive, and the blanket wrapped around me like a warm embrace. My own bed and blanket were decent, but they paled in comparison to hers.

"Hehe, your expression says it all… I've already told Yeonhee, so the new bed and furniture will arrive tomorrow," she said, noticing my awe.

"Ah, yes… thank you," I replied, feeling a little embarrassed for showing such a childishly excited expression. But my mother-in-law didn't seem to mind.

"Now, come closer," she said, patting the space beside her.

"Y-yes…" I obliged, moving closer despite the bed being large enough for three people to sleep comfortably.

Squish.

'H-her breasts are so soft…'

It reminded me of lying in bed with Yeonji, but the fact that the person next to me wasn't her but my mother-in-law made me uneasy.

"It's okay… everything will be fine… so for now, sleep comfortably, Master♥," she said, her voice soothing.

"Yes… Mother-in-law," I replied, feeling a warmth I hadn't experienced before.

It was different from the love I felt with Yeonji. This felt more like the love of a mother, and my heart began to relax.

'Come to think of it, I've never really been loved properly… is this the first time…?'

I'd been abandoned at an orphanage shortly after birth and grew up with other children in similar situations. I'd never known a mother's love, but the way my mother-in-law held me felt like what I imagined it might be.

'Still… it feels good…'

As I lay in her warm embrace, my tension eased, and my eyes began to close. My mother-in-law smiled gently at me—not the vulgar smile of a lustful woman, but the gentle smile of a caring mother.

'I think… I'm going to fall… asleep…'

Just as my eyes were slowly closing, lulled by her affection…

Throb.

"Oh my♥," she murmured.

My penis, with no regard for the situation, began to harden again.

'Why is this thing doing whatever it wants…'

While I was drifting off, my body had other ideas, and my erection pressed against my mother-in-law's thigh.

"You came so much earlier, but you're still getting erect like this… you're really an amazing Master♥," she said, clearly amused.

She stroked my head with one hand while using the other to gently touch my penis, her actions a mix of maternal care and lewdness.

'This… feels good…'

As sleepiness and pleasure washed over me, my eyes began to close again.

"Hehehe♥ Master… no, Juhyun is still a child♥," she said, her tone full of affection.

Without realizing it, I snuggled deeper into her chest and pushed my penis between her legs, acting like a spoiled child.

"Haa♥ Your actions are still like a child, but… down there, you're a completely magnificent male♥," she teased.

Squish, squish, squish, squish, squish.

When it became difficult to continue with her hand, she shifted slightly, placing my penis between her thighs and beginning to move her hips. Her upper body remained still, her movements subtle so as not to disturb my sleep.

'Ah… I think I'm going to cum… I shouldn't cum…'

I was already half-asleep, my body no longer under my control. I felt myself nearing climax, but I couldn't bring myself to speak.

"Now, put it in mommy's pussy and cum as much as you want♥," she whispered, guiding me inside her.

Squish.

"Hmm…"

"Hngh♥"

Her tight, wet pussy made me ejaculate almost instantly. The amount was less than before, but it was enough to fill her.

"My son came so hard in mommy's pussy♥… Thank you♥," she said, her voice a mix of maternal warmth and lewd satisfaction.

In her embrace, I finally fell asleep.

...

The next morning.

Squish… Squeeze.

'Hmm… soft.'

My consciousness slowly returned. My eyes weren't open yet, but my hand, moving instinctively, grasped something soft near my face.

Squish, squish, squish, squish.

I kept touching the softness, unable to stop myself…

"Aah♥"

"M-Mother-in-law?!" I exclaimed, fully awake now.

"Hehehe♥… You're still a baby, Master♥," she said, smiling as she looked down at me.

My hand was gripping her large breast, and I felt my face flush with embarrassment.

'What did I do last night…'

I remembered not the training or the sex, but how I'd clung to her like a child, and my cheeks burned.

"It's okay… I've already investigated everything about you, Lee… I understand that you miss your mother," she said softly.

"T-thank you… Mother-in-law… But wait, investigation?! What do you m…" I started, but she cut me off.

"Well, Yeonji will be waking up soon… wouldn't it be better for you to go back to your room, Master?" she suggested.

I had no choice but to get up and head back to my room through the secret passage in the wall.

Squish.

"Haa♥… To come this much even while sleeping… it's incomparable to my husband♥," she murmured to herself after I left.

She lifted the blanket and looked at her pussy, already stained with sticky semen. She'd cleaned me up before I woke, so I hadn't noticed, but I'd made her climax multiple times even in my sleep.

"To do this while sleeping… you're more… suitable to be my Master than I thought♥," she said, her evaluation of me rising in my absence.

I quickly washed up and changed my clothes, trying to push the memories of the night out of my mind.

'They said the new bed and furniture would arrive today… I shouldn't go to my mother-in-law's room for a while…'

My face flushed again as I remembered how I'd unknowingly thought of her as my mother and hugged her. I decided to avoid her room for a while to keep those thoughts at bay.

Knock knock knock knock knock knock knock.

"Oppa~!♥" Yeonji's cheerful voice called as she opened the door and ran to me, hugging me tightly.

'Come to think of it, this is probably the first time we've seen each other's faces in the morning like this.'

Even when we met at night, I'd always gone home before it got too late, and our busy schedules made weekday meetings rare.

"Hehehe… I'm so happy to see you in the morning, Oppa…" she said, her smile bright.

"I was about to go first… you came early," I replied, smiling back.

"Yeah, I had a first-period class today, so I woke up early, hehe," she said.

As I looked at Yeonji's cute, smiling face, the events of the previous night faded from my mind. I hugged her back, feeling a sense of normalcy return.
