REINCARNATED IN "THE NOVEL´S EXTRA"

...

"What are you waiting for, then?"

She asked, trying to hide her nervousness.

"Let's go, my student.The night is long."

I approached and touched her lips again, this time slowly, giving her time to follow. Her eyes were open, watching every movement. With each second, the atmosphere between us grew warmer and more intimate.

One hand rose to her slim, flexible waist, while the other supported her on her pristine, white neck.

She followed my rhythm, but, unlike before, she was more relaxed and aware of what she wanted. Her eyes, though reluctant at first, maintained eye contact with me longer than we expected. And when she finally understood a little of what to do, we closed our eyes.

After a few minutes, we broke the kiss again. This time, Nayun was smiling, with an expression of pure satisfaction.

"You... definitely have a talent for this."

She said with a smile. Her molar was truly a charm of its own, now that I saw it up close.

"Ah, so you're already feeling like an expert?" I teased back.

She shrugged, her face still flushed but now full of confidence.

"Maybe I need a few more lessons... You know, just to make sure I'm really learning."

Anyone looking at Nayun from afar would think she was some kind of tsundere. But I, who knew her, knew that wasn't quite the case. She could be hot-headed and easily irritated, but she was genuine when she wanted to be and didn't hesitate to say what was on her mind.

"Well, if you're asking, I'll give you as many lessons as you want today."

I replied with a mischievous smile.

"I think it would be good for you to take that off."

I added, glancing at the blue blazer she was wearing. She was slightly sweaty on her neck due to the heat caused by our previous actions.

"It's true... It's really hot here!"

After fanning herself with her hands, Nayun removed the jacket and tossed it aside.

"Don't look at me like that!"

"Ah! Sorry, I remembered the beautiful sight from earlier."

Theo found himself staring into the distance.

"Pervert! You pervert!"

Red as a tomato, Nayun curled up in my arms, hiding her face against my chest, trying to stifle her embarrassment. Her attitude was a contrast to her earlier boldness, which only made the situation more charming.

I couldn't help but smile as I fell back, pulling her with me, lying down on the sofa. With her nestled on top of me, I began to gently stroke her hair, feeling the soft touch sliding between my fingers.

"Hum... Theo?"

Her voice was hesitant, almost a whisper, as if she were carefully pondering her next words.

"Yes, go ahead..."

I replied, looking at the ceiling while continuing to stroke her hair.

She was silent for a moment, perhaps reflecting on what she was about to say.

Then, with a slight sigh, she finally spoke.

"Our relationship... I wonder what it will be like."

Her question floated in the air, filled with uncertainty. We both knew it wasn't something simple.

"Normal wouldn't be... Even if we wanted it to be."

I admitted, knowing we were treading on complicated ground. After all, unlike her, I already knew what I wanted.

Nayun let out a soft laugh, perhaps to ease the tension.

Even though we were in the 21st century, where it was common to kiss and even sleep with people we barely knew, our situation was quite different.

I didn't just want a moment with her. And I was sure she wouldn't want things to end like that either.

"Well... I know you don't feel the same way I do, but that's not a big problem."

It was sad, but what could I do? Force her to like me? No, I wouldn't do that even if it were the last option.

"I wouldn't say I don't feel anything. If there were no feelings at all, something like this wouldn't even cross my mind. I gave my first kiss to a guy I just met. Understand? It's really crazy."

Of course, I understood. It never crossed my mind that, on my first day in this world, I would already be kissing one of the heroines of my favorite work, especially the girl I liked the most.

"Anyway, the future is ours, so there's no point in worrying too much."

Time was something we had plenty of, whether here in the Cube or out there. We both had as much time as we wanted to progress in our relationship.

With the question about the relationship almost resolved, Theo quickly changed the subject.

"Nayun, about your brother, how about I go see him this week?"

"Huh? Really?! Don't you need to prepare or something?"

The girl, lying on my chest, asked enthusiastically...

"No, waking him up is quite simple."

Hearing my words, Nayun was thoughtful for a few seconds.

"We can go on the weekend. Sunday, if that's okay with you."

The reason she hadn't asked me to go before was because of her father, who was almost 24/7 watching over the room where Chae Jinyoon was hospitalized. He believed that at any moment his son could wake up after receiving the elixir.

So, to avoid any misunderstanding by bringing Theo, she decided to wait until Sunday, the day her father would be on a business trip.

"Deal, then."

Seeing that there was no reason to question why we could only go on Sunday, I promptly agreed.

"Thank you, Theo!"

"Not yet. Save the thanks for when he wakes up."

Thanking him when he hadn't done anything yet didn't make much sense.

"But that doesn't mean I'll refuse if you want to."

With a cheeky smile on my face, I spoke to Nayun, who looked at me with eyes that already understood my words.

"Tsk! What was I thinking getting involved with you."

Clicking her tongue, she approached my face pretending reluctance. When we were about to kiss, Nayun changed direction to my neck and, reaching where she wanted, licked it gently before biting it.

"Nayun, you... Mmhg!"

A surprised grunt escaped my lips, and my whole body trembled slightly.

I really didn't expect her to bite and suck my neck; this action caught me completely off guard.

"Nayun... Where did you learn that?"

"Pff! It's not just you men who watch inappropriate shows, Theo. We women watch them too."

Like a mischievous little fox, she whispered seductively, her words hitting my mind like a wave.

"...In those videos, the women always licked and bit their partners' necks, and guess what? Their reactions were always funny. So, when I was about to kiss you, the same question came to me, will he react like that too? Look, it was amazing."

Watching my slightly flushed face, she smiled, proud of herself.

"Humpf! You've been taking advantage of me since the beginning... But this is just the start. Hehehe!"

Still with a soft smile on her lips, Nayun stared at me intently.

"Hum? What's this feeling that I messed with something I shouldn't have? No... it's just in my head..."

Nayun shook her head, ignoring the slight unease.

"Hey... I didn't know you had such a cute side..."

Her words were interrupted by my lips, which pressed against hers.

It was so sudden and quick that, even though she was a rank 4 cadet, Nayun couldn't react.

"Damn..."

She cursed herself, not expecting me to kiss her, especially when it seemed like she had everything under control. It was foolish of her, considering what we had already done up to now.

"Hah!"

Under the sudden kiss, she completely surrendered, ignoring what she wanted before.

"You're quite a bold girl, and girls like that need to be punished."

Before she could respond, I held her firmly, sliding my hands to her buttocks and pulling her closer, until there was no space between us.

My hands in that area surprised her, making her gasp and arch her body.

"Ugghh!"

This time it was her who moaned loudly, even more than me. Her eyes became cloudy, and her body was overwhelmed by a wave of pleasure. I didn't waste time and kissed her again, only this time, the kiss was different, much more intense.

With her still on my lips and her hands on my back, I continued to stimulate her, caressing her butt and squeezing lightly.

After a few moments, I did something new, my tongue gently advanced, crossing the barrier of her lips.

Nayun, lost in my touches, felt this new presence and, instead of retreating, welcomed it, advancing with her own tongue. Any doubts she had disappeared; she knew what I wanted.

As soon as our tongues met, the kiss turned into a slow but intense dance, a silent battle for dominance. Nayun, still inexperienced, naturally yielded to the lead, feeling taken by the rhythm I set, savoring every second of the intimate exchange.

As the kiss intensified, Nayun began to feel a slight discomfort in her position. Noticing this, Theo gently adjusted them, guiding her until I was on top, naturally taking control.

Our mouths never parted, and she found herself unable to resist the growing desire.

Instinctively, Nayun slipped her hand under my shirt, exploring the unknown.

Her fingers traced invisible lines across my skin, while she continued to feel the firmness of my muscles, light shivers caused by her caresses flooded.

It was like discovering a new world, where every touch provoked an almost electric reaction in my body, making my brother down there start to wake up with such excitement, but with great mental effort I was able to keep him under control for now.

After regaining my composure, I watched attentively the way she explored with innocent curiosity.

"Aahh!"

After a long time without a break, Nayun finally needed a moment. Panting, with her chest rising and falling, she stared at me with glazed eyes, a thin line of saliva connecting us appeared before our eyes.

"Aah! Phew! That was... long... really long..."
