Stealing the Heroine's First Kiss
“Hya! Ahn! Nngh…!?”
Slap!
I gripped Seo Ahyeon’s pelvis firmly with both hands and drove my hips forward in a relentless series of powerful thrusts.
Each time our bodies connected, flesh slapped wetly against flesh, and the lewd, sticky sounds of our joining echoed through the room without pause.
Seo Ahyeon clutched the bedsheets tightly in both fists, her delicate little body trembling like a leaf.
The sweet cries spilling from her lips pierced my ears and kept my arousal at a perfect, simmering peak.
“Haa…”
What had been nothing more than the faint scent of air freshener just dozens of minutes ago was now thick with the unmistakable, intimate aroma of a man and woman—our combined scent saturating the break room.
I wiped the sweat rolling down my forehead and once again seized Seo Ahyeon’s ass with rough hands.
“Hyeet… hek… uunh.”
After only a few deep strokes, her eyes had already gone hazy and unfocused as she panted helplessly.
Between her slack, half-open lips, a dainty tongue lolled out, twitching cutely in time with every thrust.
…Look at that face.
I drank in her lewd, adorable expression for a moment before the lust boiling inside me surged past the point of control. I dropped my stance lower at once.
The sudden change made my cock curve inside her, pressing firmly against the soft wall of her belly. Seo Ahyeon’s head snapped back instantly.
Those dreamy eyes flew wide at the unbearable stimulation.
I caught her lifted chin in perfect timing and leaned down.
As I closed the distance without hesitation, Seo Ahyeon—quick to understand—realized what I wanted. She gently closed her eyes for me.
Her face was already flushed dark with raw, unmistakable anticipation she couldn’t possibly hide.
Chu—
“…Huuup.”
I gave her exactly what she wanted without delay—pressing our lips together hard and sliding my tongue deep inside.
…Come to think of it.
I watched her twitch and tremble beneath my deep kiss, eyes closed in open pleasure, and thought to myself.
Come to think of it, because of Baek Seolah’s fierce resistance, I still hadn’t managed to kiss her even once.
By that measure, among all the heroines of the original story, the first one whose lips I claimed was Seo Ahyeon right here, right now.
The realization sent an intense thrill racing through me. I explored her mouth more greedily—pushing my tongue in, pressing it down, licking every inch.
Chuuup—
“Hyeep… mmm… huht…”
Seo Ahyeon let out short, breathy, almost nasal moans as she gradually drowned in our kiss.
Before long her half-lidded violet eyes had grown heavy with a sensuality I had never seen before—utterly obscene.
She didn’t resist my kiss at all. She opened her lips obediently for my tongue, then began responding with her own shy initiative.
…This is insane. Seriously.
The sight of this original heroine—a girl who still technically had a boyfriend—behaving so lewdly made heat surge through my entire body.
How could she be this erotic? The way her eyes shimmered with affection that seemed to grow stronger for me in real time, the way her face burned crimson with pleasure.
Unintentionally, I was beginning to understand why the original Han Taeyang had been so obsessed with stealing other men’s women.
Especially since I had already ended up embracing another man’s girlfriend twice now—completely by accident.
This was unmistakably… a moment and a situation that couldn’t even begin to compare with a simple one-night stand with some senior or classmate.
It felt like my lower body might burst at any second.
Still, it probably wasn’t good manners to think about other women for too long while buried inside her.
I shook off the stray thoughts and pushed my upper body upright again.
“Ah…”
Seo Ahyeon’s face fell into an adorably sulky expression, as though she were swallowing her disappointment at the abruptly ended kiss.
Even that tiny reaction was enough to make my lips curl. She really did have a dangerous talent for driving men crazy.
“Don’t get too impatient. I can give you as many kisses as you want from now on.”
“…Hyeet.”
I shifted the hand that had been gripping her pelvis, adjusting my angle as I spoke.
Specifically, I moved toward one of the other secret places she had been showing me throughout this entire rear-entry session.
While rubbing the pretty, soft-pink ring of her back entrance with my thumb, I added in a low voice.

“If you ever want to kiss, just come find me anytime. Say the word and I’ll do it as much as you like—even right in front of Kim Minjun.”
“Hngh, ah, w-wait… th-that place…”
Seo Ahyeon’s face flooded with a completely different shade of red than before.
I thought I had said something rather nice, but it seemed she had no mental bandwidth left to appreciate it.
Despite my kind offer, her eyes trembled and one hand flailed weakly in the air.
“D-don’t… don’t touch there. I-I’m really, really embarrassed…”
“……”
“I-if you want it, I’ll mentally prepare myself next time, okay? So… so today, let’s just stop here…?”
She spoke with a faint, coaxing smile, as if trying to soothe a stubborn child.
I didn’t particularly like the tone—like she was trying to placate me—but.
…Well, today isn’t the only day we have.
Just as she said, there would be plenty of chances later. No need to get greedy.
“…Uunh.”
In the end, I traced one last slow line across her anus with my index finger before pulling my hand away.
For someone who had begged me to stop because it was embarrassing, her inner walls had clamped down even harder the moment I touched her.
Sometimes there were desires people didn’t want to admit—even to themselves—because acknowledging them was simply too shameful.
There were ways to awaken those desires quickly, but as I had said, there was no reason to rush.
I gave a soft chuckle as I looked at Seo Ahyeon—eyes rolled back lewdly, lips bitten tight.
“Alright. We’ll stop here for today. Next time, make sure you come prepared like you promised, got it?”
“Ah… ahhup. You’re really… such a bully.”
“Sorry, sorry.”
When she turned to glare at me resentfully for my mischievous words, I immediately switched into gentle aftercare mode.
Once again I smiled brightly and stroked her glossy black hair with slow, tender fingers.
Seo Ahyeon tilted her chin up slightly to make it easier for me to pet her, all while grumbling in obvious discontent.
“…It really feels like I’m being trained. You keep giving me the sickness and then the medicine. Or is it just my imagination?”
“Yeah. It’s just your imagination.”
“……”
Seo Ahyeon shot me a silent, sulky glare.
She had clearly caught on to the fact that I was teasing her.
I quickened the hand stroking her hair, and though one of her eyebrows twitched in protest, she soon buried her face comfortably into the pillow.
Then, in a sweet, contented voice, she murmured.
“I’ll let it slide just this once, Han Taeyang… Do better from now on…?”
“Yes, ma’am. Your wish is my command.”
I answered with an exaggerated, theatrical tone and a quiet laugh. Seo Ahyeon gave me another sharp side-eye, but.
I caught the way the corner of her mouth twitched upward, as if her mood wasn’t entirely bad.
It seemed my playful title had pleased her more than she wanted to admit.
Shlup—
“…Mmm, huut.”
At the right moment I pushed the half-withdrawn length of my cock back into her slick heat.
Seo Ahyeon—already thoroughly stimulated—let out another sweet, delighted moan.
“I’m about to cum, Ahyeon.”
I narrowed my eyes slightly at the rising climax and steadied my breathing.
The moment she gave a silent, blushing nod, I snapped my hips forward.
First came the deep, heavy thrust—my cock driving all the way in to press firmly against her cervix.
Then Seo Ahyeon’s shoulders and shoulder blades twitched as she let out a tiny, blissful sigh.
And finally—
“…Huuup.”
After several more perfectly timed strokes, I released.
Spurt, spurt—!
My cock throbbed inside her narrow passage and poured thick, white seed into the condom.
Unfortunately, because of the barrier, I couldn’t paint her womb the way I wanted.
“…Hngh, hyak… heuk, ut.”
Seo Ahyeon buried her face in the pillow as if she didn’t want to show her embarrassed expression, yet the erotic sounds she made made it clear she was more than satisfied.
From this angle I could still see one flushed cheek burning crimson, the blush spreading all the way to her ears and the nape of her neck.
“Haa…”
Only then did I let out a long sigh, savoring the pleasant exhaustion flooding my body, and reached out once more.
The finishing touch. Mischievously, my fingers swept across her back entrance one last time.
“…Ut!”
Seo Ahyeon, who had been riding the same wave of orgasm, was caught off guard. The sudden extra stimulation made her waist quiver violently.
And of course—
Splash—
Thud!
“Ow.”
“Die. You pervert. Seriously, just die already.”
Later, while we washed our bodies together, I received a solid slap on the back from a deeply embarrassed Seo Ahyeon.
It didn’t hurt much. Thankfully she hadn’t infused it with mana this time.
I had been laughing when I accidentally pushed her too far and earned a hard bite on the shoulder, but.
Well, wasn’t that something of an honorable medal?
Hmm.
Or maybe not?
If not, then never mind.
