Professor Kim's Home Visit (4)

Ding-dong~ Ding-dong~ The cheerful chime of the doorbell echoed through the hallway. Moments after it rang, footsteps approached from inside. Then came Cha Eun-ju's voice.

"Who is it~?"

"Ah... hel..." For a split second, I almost answered "Hello?" ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠out of habit. The last two times we'd crossed paths, the greetings had been so natural that the words nearly slipped out again.

No. Right now, I'm Professor Kim Byung-yoon.

I was Professor Kim Byung-yoon—the man who had lured Cha Eun-young with the promise of grades and taken her pristine body as payment. The same professor who had filmed the act and used the footage to claim her older sister, Cha Eun-ju. The man who had successfully ensnared both beautiful mixed-blood sisters.

I swallowed hard and straightened my posture.

After sharing a bed with both sisters, they were already firmly in the palm of my hand. Cha Eun-young had grown noticeably more obedient, her resistance crumbling whenever she had to entertain the old professor. And Cha Eun-ju? She would be even easier to handle. The last time I saw her, she had already been half-lost in pleasure. Her husband had probably never once satisfied her. In fact, he might have been her first and only partner—meaning she had never truly experienced real pleasure from a man until I gave it to her. Once she tasted that ecstasy, she would obey my every word. She had even helped hold her own sister down while I had my way with her. She was completely broken in. So as long as I maintained the perception alteration that made me Professor Kim Byung-yoon, she would submit without question.

All that remained was to enjoy her glamorous, voluptuous body.

I opened my mouth again, this time speaking as Professor Kim Byung-yoon.

"Miss Eun-ju."

"Yes?"

"Miss Eun-ju~"

"Professor Kim Byung-yoon...?"

Her beautiful voice carried a hint of surprise through the intercom. For a moment, silence followed. Just as I began to wonder why she hadn't added the honorific "nim," I heard the click of the lock.

The front door swung open, revealing Cha Eun-ju's face. Her fair, Western features, clear brown eyes, and distinctly mixed-blood beauty were on full display. Her eyes widened in shock at the sudden visit. Worried she might slam the door shut, I pushed it open wider and stepped inside without hesitation.

She stumbled back in surprise as I entered, my shoes brushing past the ones already on the floor. I closed the door firmly behind me.

"How did you..."

She trailed off, but I had no intention of explaining. Instead, I asked with feigned innocence, "Why? Is it a problem for me to be here, Miss Eun-ju?"

"O-of course it is..."

I ignored her protest and removed my shoes, taking in the layout. The entrance had a full-length mirror on the left ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠wall and a shoe cabinet on the right. Straight ahead lay the living room. To the right was the bathroom; turning left led to one bedroom. The kitchen and dining area were on the left side, with another bedroom further in. The floor plan was identical to my own home, so I navigated it easily.

I stepped into the house. Cha Eun-ju, who had retreated when I entered, backed up again toward the living room as I finished removing my shoes. The home she shared with her family carried a subtle, pleasant scent—the unique fragrance created by its residents. It spoke of quiet happiness, as if the entire house were affirming that its occupants were content.

A sly smile crept across my lips. I intended to mix my own scent into that happy fragrance.

I approached her and placed both hands on her slender waist—the same waist I had admired from behind earlier. The elegant curve and the soft fullness beneath my palms drew an obscene grin from me.

But contrary to my expectation that she would yield easily, Cha Eun-ju's eyes widened in alarm. She gently pushed my arms away with both hands.

"Please stop... I... I heard everything from Eun-young..."

...Huh?

I had assumed she was already completely under Professor Kim Byung-yoon's control, yet here she was rejecting my touch. She continued, her voice trembling.

"The video of you and Eun-young having sex in your office... She told me it was all a lie. That you fabricated everything..."

Apparently, the sisters had talked after the last incident. Now she knew the truth—that the footage had been a trap, that the professor had cut his own face out of the video to blackmail them both.

While I stood momentarily stunned by her unexpected resistance, the faint scent of happiness wafted past my nose again. She was trying to put that one mistake behind her and return to her family.

Did she really believe she could undo what had happened?

Heh...

I sneered inwardly. After indulging so deeply in pleasure, she thought she could simply go back to being a loving wife and devoted mother? The idea was laughable.

I decided to remind her that there was no going back. The moment she had fallen into the professor's trap—even once—she could never again be the cherished wife or the mother of her child. Just like a single taste of a drug was enough to create an irreversible addiction, she was already lost.

I spoke softly. "Miss Eun-ju... I've recorded a video of us having sex, just like I did with Eun-young. What do you think your husband will do if he sees it?"

Cha Eun-ju let out a strangled cry. "N-no! You can't!"

Her hands, which had been pushing me away, froze. Of course, I hadn't actually filmed anything—though it was possible the real Professor Kim Byung-yoon had hidden cameras. That detail hardly mattered now.

"Th-that's..."

The anxiety that had been flickering in her eyes since I arrived finally crystallized into full-blown panic. She understood the trap she was in.

I placed my hands back on her slender waist. This time, she didn't resist. I leaned in to kiss her. She turned her head, so my lips landed on the pale column of her neck instead. The soft, warm skin met my mouth, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠carrying the fresh scent of soap. She must have showered early and already taken her child to daycare.

Her hands gripped my arms again, trembling. "W-wait a moment..."

When she tried to resist once more, I pulled back with a slight frown. "Miss Eun-ju, if you won't listen to reason—"

"No, it's not that..." She met my gaze, her beautiful eyes filled with fear and confusion. Her voice shook as she whispered, "I... I don't have any condoms..."

...What?

The excuse was so flimsy I almost laughed. I ignored it and began slowly lifting the hem of her long dress. Inch by inch, her pale legs came into view—ankles, calves, then smooth, creamy thighs.

She pushed my hands down again, more urgently this time. "Really, without a condom... we can't. If you go buy some, I'll do it. I promise."

Huh?

Something felt off. I had already come inside her raw before. Why the sudden insistence now? She seemed to read the question in my eyes.

"Today... we really can't do it without protection..."

What the hell...?

Then my gaze caught the large calendar hanging on the wall. Today's date was circled in red with a big heart drawn inside it. Written within the heart were the words: "Making a little sibling for Yoon-woo ♥"

Another tiny heart sat beside it. It looked like... a planned pregnancy. I recalled hearing that more couples were scheduling pregnancies carefully these days—men visiting urologists to ensure healthy sperm, women managing their diets and tracking ovulation through gynecologist visits. They timed intercourse precisely on fertile days to conceive a healthy child.

Judging by the calendar, Cha Eun-ju had been tracking her cycle and preparing her body. Today was supposed to be the day she and her husband tried for another baby.

She spoke again, voice tight with desperation. "If you go buy condoms... I'll really do it. But we can't without one..."

Hmm...

For someone who had already been thoroughly compromised, she was surprisingly firm. My hands still rested on her waist as I considered my options. Running to the nearest convenience store would take at least fifteen minutes round-trip. Wasting that much of the one-hour perception alteration window on a condom run was unacceptable.

Besides... the fact that she was refusing without protection only made me want it more. The thought of filling the body she had so carefully prepared for a healthy child with my seed was irresistibly tempting.

What should I do...? Should I just force the issue with blackmail?

Even after bringing up the sex tape, she remained resolute. Then a memory surfaced. I slipped one hand into my pocket and rummaged around until my fingers closed around the quest item I needed.

When I withdrew my hand, a small rectangular paper box no larger than my finger rested on my palm. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠The item's description appeared in my mind.

A satisfied smile spread across my face.
