Chapter 111: Sex Optimization Mode
Yeon Ji-yoon lay sprawled on the floor.
A mixture of my semen and her juices flowed heavily from her pussy.
With her eyes half-unfocused and her mouth hanging open, she clearly must have enjoyed it.
"This is pretty useful."
Yeon Ji-yoon is useful, and the "Sex!" skill I leveled up to 10 is useful too.
Fearing it might hurt if I just shoved it into a dry pussy, I had used 5 Mana to secrete Pleasure Pheromones before I started.
The effect seemed quite instantaneous, considering she was letting out moans instead of cries of pain.
And the experience of my cock growing was also quite fascinating.
Normally, I never thought of my cock as small.
It wasn't monstrously huge like the ones in porn, but it was just right.
Hard, thick, and reasonably long.
That was my own objective assessment of my cock.
I might not be the most handsome guy, but when it came to my cock, I figured I was better off than those pretty boys.
I’d lived with that pride, and since Kim Ji-hee’s reactions didn't seem like she was faking it, I’d assumed it was just about that level.
However, as I pushed inside, I could definitely feel my cock hardening and shifting to fit Yeon Ji-yoon perfectly.
It didn't get massively larger, but seeing her raw reactions—so different from when I was with Kim Ji-hee or Oh Se-i—I realized this was what it meant to transform into the optimal shape and size.
What followed wasn't much different from usual.
Just by thrusting however I wanted, she would scream as if she were losing her mind and crawl across the floor. That only made me hornier, so I hammered into her even harder. Watching her pussy tighten while she was still wearing that doctor’s gown made me blow a massive load deep inside her.
I rolled Yeon Ji-yoon over, as she was practically one with the floor, and pressed my cock against her mouth.
"Time to clean up."
Her eyes flickered toward my cock.
The moment I pressed it against her lips, her tongue came out to meet it, licking and swallowing everything smeared on it.
She sucked and swallowed all the way to the root as if she were determined to clean it perfectly.
A message popped up saying my stats had increased by 3★ due to the Refreshment effect, along with another message saying I had gained a "Special" buff.
The buff I received was "Coin Acquisition +50%."
Since coin acquisition isn't a particularly meaningful stat for me right now, I didn't think it was that great, but it did make me realize that some pretty decent buffs could come from this.
After all, a 50% increase in coins is a huge number if you just look at the value.
I wondered if they stacked.
Curious, I pulled Yeon Ji-yoon up and sat her on top of me.
I aligned her pussy with my cock, which was already standing tall again, and slid it in.
"..."
There was a faint look of fear in her eyes.
But she had no option to resist.
"Hee-uung..."
As her pussy took in the surging cock, Yeon Ji-yoon wrapped her arms around my neck, feeling it pierce deep inside her.
She was still wearing the doctor’s gown, and her blouse was pushed up, exposing only her breasts. Our chests were pressed together, with only our genitals joined.
Even though we were just staying still, her pussy twitched and squeezed my cock.
The stimulation was making her muscles react naturally.
I could tell just by how she clung to my neck, trying to keep me from moving because she couldn't handle any more.
But I couldn't just stay like this.
The way her pussy writhed as if sucking on my cock was stimulating, but the sensation of pistoning was far better.
I also loved how my cock adjusted to fit perfectly inside; every time I pulled out and pushed back in, the sensation of her pussy clinging to me like a suction cup as it slid and twitched was incredibly intense.
Holding Yeon Ji-yoon like that, I lifted her up and down.
Every time she came down, as if being pounded by a mortar, the raw moans in my ear sounded like the primal instincts of a depraved woman, which turned me on even more.
I stood up from the spot, holding Yeon Ji-yoon, and this time I moved my hips.
"Haaaah! Please... Aaah!!"
You need good strength for a lift-and-fuck.
To move your hips while holding a woman, you don't just have to endure a weight of at least 50kg; you have to carry it and move.
In fact, you can't just endure it; you have to apply force so she doesn't slip down.
Fortunately, Yeon Ji-yoon seemed to enjoy being fucked in mid-air.
Panting with her tongue out, she leaned in to kiss me, as if she couldn't take it anymore.
I was making a woman who was highly educated and used to looking down on others beg and wail like an animal.
The saying that all women are the same once you strip them down doesn't hold true, whether in a zombie apocalypse or in my previous life.
Even if they're the same "woman," the thrill of conquest for a man differs depending on her profession and status.
This time, water was literally streaming from her pussy while I was thrusting.
"I'm... I'm going to..."
She was a total easy-come pussy.
Whether she was soaking the floor or not, I kept doing my job.
Her pussy, sensitized to the extreme, reacted to every single movement of my cock, tightening and loosening repeatedly even without me using Pleasure Pheromones.
Once again, I poured a massive amount of semen into Yeon Ji-yoon’s womb.
Unfortunately, it seemed the "Special" buffs didn't stack.
It looked like I could refresh the existing buff, but this time "Mana Recovery Rate +50%" appeared, so I didn't change it for now.
I tossed Yeon Ji-yoon, who was still clinging to me to avoid falling, onto the sofa.
Her coffee-colored stockings were already torn around the crotch and soiled with leaked semen and fluids. Her skirt was bunched at her waist, and her bra and blouse were pushed up.
Her firm breasts, which looked to be about a C-cup, created a contradictory and erotic mismatch with the wide-spread doctor’s gown and her noble-looking face.
Taking the doctor in was definitely a stroke of genius.
Leaving the sprawled-out Yeon Ji-yoon behind, I went through the connected passage to the hot spring to wash up and soak my body in the tub.
"Phew. This is the life."
I didn't regret investing Normal Mode Points to level up "Sex!"
In fact, I was beyond satisfied.
It was right to level up the Sex Mode once I had some breathing room.
The fact that I have sex solely for my own satisfaction hasn't changed.
That thought remains the same, but I’ve confirmed that by leveling up the Sex Mode, the woman becomes more satisfied and enjoys it more without me having to do anything extra. And when she loses her mind like that, it adds to my own arousal, making for a more satisfying experience.
I wonder if Kim Ji-hee will like it too.
It feels a bit like I'm getting help from a skill, but it also feels like my pride as a man is getting a boost.
When I finished washing and came out, Kim Ji-hee had returned.
She was just coming back after looking after Yeon Ji-yoon and guiding her to the first-floor bathroom.
"Oppa. What happened to that unnie? She’s practically exhausted."
"I just fucked the life out of her."
"..."
Her gaze flickered toward my cock as I walked in naked.
It was an absurd look, as if she were thinking, You? Really?
"What’s with that look?"
"Nothing..."
"It’s definitely not nothing."
Well, I understand.
Enjoying sex and feeling like you're going crazy from it are two different kinds of pleasure.
"You need to be disciplined today."
"...Eh? Right now?"
Kim Ji-hee has been getting a bit cheeky lately, so I need to re-establish the hierarchy.
It means she feels more comfortable around me and that trust has been built, so as long as she isn't being a total bitch, I actually enjoy this kind of playfulness. But enjoying it is one thing, and disciplining her is another.
Now that I’ve obtained this Sex Optimization Mode, it’s only natural to let Kim Ji-hee taste it as soon as possible.
As I approached her with serious intent, Kim Ji-hee stepped back in flustered surprise.
Her eyes seemed to say: Yeon Ji-yoon is washing up right behind that door, and we can hear the water—you want to do it here?
I wonder if Kim Ji-hee knows.
That those looks of hers always drive me crazy.
I grabbed the back of her neck and kissed her while sliding my hand down into her pants.
"Hng..."
Contrary to her words, she immediately let out a faint moan and reflexively touched my cock.
She knows now.
She knows that by touching it quickly and getting at least a little pre-cum flowing, she can take it more easily.
She’s been conditioned.
"Ah-hng...!"
I rubbed her clit and then slid a finger into her pussy, which was starting to get slightly moist.
The hand that had been softly stroking my cock tightened its grip.
My cock was already screaming to be put inside.
I pulled my finger out, lifted one of Kim Ji-hee’s legs, and shoved it in.
"...!"
The eyes that had been locked with mine in a kiss were filled with bewilderment.
She wrapped both arms around my neck, sharing the burden of the balance that was hard to maintain on one leg.
Kim Ji-hee’s back hit the bathroom door.
The sound of running water could still be heard from inside.
Squelch. Squelch.
"Ha-eut!!"
With one leg raised, the cock buried itself even deeper, and Kim Ji-hee couldn't help but let out a moan.
Then, she looked back in surprise, which was quite cute.
Kim Ji-hee’s pussy was already so tight that I couldn't feel a massive difference.
However, her reaction had definitely changed, even if subtly.
"Oppa... hng... I feel strange... be gentle..."
I fucked her as hard as I wanted.
The cocky look she’d given me earlier was nowhere to be found; her eyes were full of desperation as she faithfully sucked on my tongue and pleaded.
She didn't want to make a sound.
She didn't want Yeon Ji-yoon to find out.
Seeing that, I thrust even harder.
"Hut! Hut! Heuu-ng...!"
Did she know that the moans she tried to swallow sounded even more erotic and loud?
I don't know if they could be heard inside.
But Kim Ji-hee was definitely feeling it more than usual.
Since I’d already proven the performance on two people, this "Sex!" mode was definitely a perfect Sex Optimization Mode.
My trust in the other Sex Modes shot up as well.
"Oppa... I... I think I'm going to go..."
Along with the pleading words in my ear, I let go of her leg and thrust deep as I ejaculated.
Her pussy clamped down hard on the cock inside her thighs, squeezing it tight.
I couldn't help but chuckle at the sight of her biting and sucking on my shoulder to stifle her moans until the very end.
I’m pretty sure she heard everything.
The sound of the water turned off a little while after Kim Ji-hee had scurried up to the second floor on trembling legs.
