The Magic City and the Great Detective
Seong-il stood in the bathroom of the magic workshop, potion bottle still in hand, as he finished sorting through his thoughts. He turned and walked back to where Yuna waited.
"How many bottles do you need?"
"Normally I'd ask for as many as possible, but..."
Even though it was only simulated intercourse, it was still undeniably selling her body. Yuna bit her lip and began to agonize over it. How should I handle this...? Should I only ask for one bottle...? But that wouldn't give me enough samples to work with...
After a long moment of internal debate, Yuna seemed to reach a decision. She opened her mouth again.
"I'm thinking at least three or four bottles. Would that be possible?"
"It is."
"!"
Yuna's eyes widened in surprise at Seong-il's unexpectedly straightforward answer. Half-accusing, she pressed him.
"If you're willing to give away three or four bottles for something like this, doesn't that mean you have a huge supply!? A-are you lying to me?!"
Ah, I guess that reaction makes sense.
Seong-il's expression grew serious as he responded.
"Watch your words! I swear on my life that this potion is something only I possess, aside from what I'm giving you. No one else can make it! If you don't believe me, go search the market yourself. I guarantee you won't find a single drop even if you look for ten years."
"Hmm....."
Yuna let out a low groan at Seong-il's confident demeanor. Seeing her reaction, he pressed his advantage.
"To be honest, I have about twenty bottles. Given the potion's life-saving properties, I originally had no intention of handing any over to anyone. But you're exactly my type, Yuna!"
"?!"
"And it's strange that you'd call your own body 'something like this.' A beauty like you would have men lining up. If I were rich, I'd come with a fortune and propose to you right away."
"Ah..?!"
"Just so you know, I'm a poor lower-class citizen who knows his place. The only way someone like me could ever sleep with a world-class beauty like you is through a deal like this. That's why I'm offering a potion I value as much as my own life!"
"..."
"So I'd appreciate it if you'd accept this transaction sincerely. If you're just going to half-ass it to kill time, I'm not interested either."
"Ah...."
Yuna was stunned by the sincerity in Seong-il's words. She carefully considered what he'd said, lost in thought. Do I really have that much appeal as a woman...? Enough for him to give up something so precious...?
Yuna had never once thought of herself as a woman in her entire life. To her, her face wasn't something to put makeup on—it was something that needed to have grease wiped off. Her breasts were nothing but obstacles that blocked her view when tightening wrenches and made her shoulders ache.
Yet here was this evaluation...
Still reeling from the shock, Yuna finally spoke.
"Alright. I'll trust that you're being sincere, Seong-il. In that spirit, I'll do my best to satisfy you as well."
"Perfect!"
Once they'd reached an agreement, Seong-il handed her four potion bottles.
"Here are four bottles. I'll be counting on you for the next eight days. Oh, and where's the shower?"
"Huh...? Suddenly...?"
"Hm. You're not doing it today?"
"That's not what I meant, but why... Ah..!"
Yuna finally understood what he was getting at. Her face flushed bright red as she lowered her head and silently pointed toward the shower room.
"That way?"
"Y-yes...."
"And a towel...?"
"I'll... hang one on the door for you."
"Got it!"
After saying that, Seong-il washed up in Yuna's workshop. He grabbed the towel hanging on the door without a word and strode boldly into the living room of the workshop, where he began drying himself off.
"!!!!!"
Even though they were about to engage in simulated sexual activity, Yuna was shocked by how casually Seong-il stood completely naked in front of her.
"Y-you... you should at least dry off inside and then come out...!"
"What's the big deal? We're going to be seeing every part of each other for the next several days anyway."
"....."
"Wouldn't you like to wash up too, Yuna? I'll wait here and get myself together in the meantime."
"....."
Yuna stood frozen, staring blankly as Seong-il diligently dried his body with the towel. After watching him for a long while in a half-dazed state, she finally snapped out of it, went to her room to grab some clothes and a towel, and headed into the shower.
Jackpot!!
Seong-il was overjoyed at this unexpected stroke of luck. Although it pained him to part with the potions... once he grew stronger in this world and returned to How to Become an Alchemist to overcome that world's crisis, he could always replenish his supply. This much loss was acceptable.
Besides, tomorrow at dawn is the absolute deadline for using the color technique.
Seong-il had a critical problem: if he didn't insert his member into a woman's body every three days, recite the incantation, and ejaculate, his brain would explode and he'd die. In that situation, giving Yuna potions in exchange for eight guaranteed ejaculations? This was a one-hundred-percent profitable deal.
If worse comes to worst, I can just space out encounters with her every two or three days until I find another woman.
With those lewd thoughts running through his mind, Seong-il sat naked on the sofa, sipping black tea as he waited for Yuna.
The door creaked open. Yuna emerged, her skin still slightly damp from the shower. Though she'd dried herself thoroughly inside, the faint moisture clinging to her skin gave her an oddly erotic appearance.
Whoa... she's killing me here.
Yuna wore leather pants and a red tank top. She turned to look for Seong-il and froze when she saw him sitting completely naked on the living room sofa.
Is this guy insane...?!
Seong-il sat with complete confidence, showing zero shame. With his legs slightly spread and his back leaning casually against the sofa, his manhood was blatantly exposed without any attempt to hide it.
It's getting a little hard...?
His cock was slightly erect, as if the situation was arousing him. Seeing it, Yuna unconsciously swallowed.
Gulp. It had been so long since she'd seen a man's penis.
How long has it been...? The last time was probably... back when I was young and stupid, learning to drink for the first time. I got drunk and was half-forced by some stranger... so about a year ago?
Thinking back on it, her body trembled as she could only stare at Seong-il.
"What are you doing? Hurry up and come here. I'm a busy man, you know."
"Huh? Ah... yes, yes..."
Yuna gathered her reluctant feelings and approached Seong-il. She struggled to walk over to him, then quietly knelt between his legs. Just as she reached out to gently stroke him—
"What are you doing?"
"Huh...? I was going to touch it first to get it hard...."
"No. Aren't you going to take off your top?"
"!!"
"Did you forget? When we made the contract earlier, the agreement included you taking off your top so I could touch your breasts."
"...I understand."
After saying that, Yuna silently pulled up her tank top and removed it. The moment the fabric cleared her neck—
Boing!
Her massive breasts, no longer restrained, bounced heavily downward.
Wow... I'm losing my mind.
The sight of her enormous, cow-like udders jiggling up and down right before his eyes made Seong-il want to immediately throw her to the floor and suck on them. But with superhuman patience, he barely held himself back.
Hold it! Hold it in!!
At the sight of her incredibly sexy upper body, Seong-il's cock swelled to the point of bursting, despite never having touched her before. Seeing his raging erection, Yuna let out a small sigh and began gently stroking it with her hand.
"Mmm...."
Her calloused palm felt slightly rough, but Yuna's touch was still soft. Seong-il leaned back fully against the sofa, tilted his head toward the ceiling, and simply enjoyed her handiwork.
After a long while of being caressed, just as he closed his eyes—
Slurp...!
"Ugh!"
The sensation of warm, wet flesh suddenly enveloping his cock.
Heh... that's the stuff.
It wasn't the sophisticated technique of someone like Eun-Wol or Piri, but her basic oral skills were solid enough. Without thinking, Seong-il gave her an evaluation.
"You're pretty good at sucking. Do you suck a lot of guys off normally?"
"!!"
Yuna's face turned beet red with shame at his comment. She quickly pulled her mouth off his cock and began making excuses.
"No! That's not it!! I had a boyfriend I dated briefly a long time ago, and he kept asking for sex... I didn't want to sleep with him, so I only gave him a few blowjobs!"
"Ah... I see, I see... Anyway, could you keep sucking? The mood's ruined now."
"...."
Yuna let out a small sigh at his words, then took his cock back into her mouth.
Slurp... Suck... Slurp...
As he enjoyed her sweet oral service, Seong-il thought, Shall we get started for real?
He began circulating his internal energy and reciting the color technique's incantation. Then he channeled his qi into both his hand and his cock, activating sensory sharing with her.
Huh?!
Yuna suddenly felt her pussy growing hot.
Why... why is this happening? Is it because it's been so long since I sucked a man...?
Although she didn't have a man, Yuna did occasionally masturbate, so she immediately recognized the sensation coming from her lower lips. Flustered by the sudden stimulation in her pussy, she paused her oral movements for a moment.
"What are you doing?"
"!"
"Hurry up and suck it."
Yuna was startled by Seong-il suddenly speaking to her in casual, disrespectful language. Just as she pulled her mouth off his cock to say something—
"Guh?"
Seong-il grabbed her head and roughly shoved his cock back into her mouth.
"Yuna. Let's stop acting like children, okay? If we've agreed to do this, we should do it properly. Why are you hesitating like some pathetic kid?"
"!!!"
The harsh verbal abuse hit Yuna without mercy. For a moment, her pride was wounded and anger surged within her, but at the same time, she felt her pussy growing even hotter.
Why?!
When she didn't resist and only looked confused, Seong-il laughed inwardly. As expected, she's a serious masochist!! Looks like I can be this rough with her without any problems.
Having roughly gauged her limits, Seong-il gripped her head and began moving it up and down like he was using an onahole.
"Ulp! U-ulp..! Ulp!!"
Even though it was painful, Yuna didn't really resist and simply let Seong-il control her head.
"Are you going to suck properly? Or not?"
"Ulp! Uuulp!!"
Water streamed from her mouth and nose as she nodded frantically. Seeing this, Seong-il naturally loosened his grip and released her.
"Haaah!!"
She pulled her face away from his cock and gasped for air. For a moment, shame and anger made her lift her head to glare at Seong-il.
"..."
She met his cold gaze looking down at her with contempt.
"!"
The moment their eyes met, the anger inside her suddenly vanished, replaced by an inexplicable fear and urge to submit. Without a word, she buried her face between his legs again.
Slurp... Suck... Slurp...
Once again, she felt the heat between his legs. The more she sucked, the hotter it became. She thought, This is strange...! When I sucked my ex-boyfriend, it never felt like this... Why?
While she silently sucked Seong-il's cock with these questions in mind—
"Hup!?"
Sudden heat bloomed in her breasts. Startled by the sensation, she continued sucking messily on his cock while looking down at her chest. There she saw Seong-il's hand kneading her breasts.
Haa... it's so hot...
Though his touch was surprising, it didn't feel bad at all. Soon she surrendered her body to his hands and began sucking his cock nonstop.
"Mmm... Hup... Slurp... Chup... Sluuurp..."
Once she'd covered his cock in saliva, Yuna used both hands to stroke his magnificent shaft, spreading her spit all over it as if applying lotion to his skin so it wouldn't drip onto the sofa.
"Hmmm..."
Seong-il let out a satisfied groan at her touch. Seeing his reaction, Yuna gained confidence. She continued caressing his balls and shaft while sucking on the glans.
"Haa..."
Yuna's blowjob continued for nearly ten minutes. By then her face was flushed red, sweat was pouring down her upper body, and she was sucking Seong-il's cock like she was possessed. Her mind grew hazy and her reason dulled. The cock before her eyes began to look lovable, and she started slowly swallowing the magnificent thing from the tip and pulling back, over and over.
Instinctively, she took Seong-il's unusually long cock all the way to the back of her throat despite its thickness, then wrapped her tongue around his shaft inside her mouth. Her head began bobbing back and forth as she performed these lewd oral techniques.
"Slurp... Sluuurp... Slurp... Gulp... Slurp... Haa..."
With one hand, Seong-il kneaded her massive breasts and pinched her nipples. Every time he tweaked her nipples, her cute little flinches made him smile with pleasure as he enjoyed the sensation of her lips and tongue wrapped around him.
His reactions fully awakened the long-dormant feminine senses inside Yuna. Her pussy between her legs began to grow wet.
Before she knew it, one of her hands had slipped between her legs and was secretly rubbing her clitoris.
"Hngh!!"
The shared pleasure flooding in from Seong-il's cock combined with her own feminine pleasure, doubling the sensation. Without realizing it, she reached a small climax and her body twitched.
Whoa... look at how soaked Yuna's pussy is.
Her lower lips were drenched as if she'd wet herself. Satisfied with her reaction, Seong-il began deliberately building up his urge to cum. Since it's the first day, shall we finish here for today?
With that thought, he grabbed Yuna's head and began thrusting roughly.
"Ulp? U-ulp? Uuuu!!"
Yuna was startled and suffocating from his sudden pistoning. But at the same time, the pleasure radiating from his cock transferred to her, melting her body and preventing any resistance.
"Ulp!! I'm cumming..!!"
Spurt. Spurt.
Grabbing the back of Yuna's head, Seong-il shoved his cock deep into her throat and ejaculated. Yuna felt the terror of death as her airway was blocked and wanted to resist, but the sudden orgasm surging from her pussy and the overwhelming desire to submit to this powerful male completely prevented her from fighting back against Seong-il.
"Huuuuuuuup!!"
With his cock buried in her throat, cutting off her air, Yuna reached climax. Her eyes rolled back from the mixture of pleasure and pain as she began to lose control of her bladder.
Sssssssssssshhhh
"Haa... that felt good. Right?"
Seong-il pulled his cock from Yuna's throat. Before his eyes was the sight of her, completely overwhelmed by the sudden excessive pleasure, passed out in a total mess.
"Aigoo......"
