The Experiment
After blasting my cum straight into Sohyun’s mouth, I took a moment to savor the lazy, deeply satisfying afterglow that still rippled through my body.
I snapped my eyes wide open, the ones I’d closed in pleasure.
My still half-hard cock flopped between my legs as I pushed myself up from the bed.
“Sohyun.”
And right then I called out to her, who was already standing at the sink spitting out the last of her rinse.
The special aftertaste had just hit me hard again, now that I’d painted her mouth. There were a few things I needed to check right now.
A little later.
Sohyun, having heard my call, approached with her face utterly blank.
I asked her to show me the stock chart on her phone.
Not mine. Hers.
While she stared back at me with that same puzzled “Why is this guy doing this again?” look.
“Here you go.”
Without a single word, she pulled up one of the solid blue-chip charts and handed me her phone.
The moment the chart on her screen filled my eyes, a single red dot appeared right beside the chart that had been frozen all weekend.
*What the hell? Does that red dot mean the starting price next week?*
I was staring at the weird “point” marker that didn’t match the usual trend line I was used to, still trying to figure out what it meant.
“!!”
Even with just a tick, the dot had dropped lower.
*Is that really the starting price?*
My mind flashed wide open.
If the future chart I usually watched on my own phone had been a clean “line” that kept moving in real time, then the red dot on Sohyun’s phone was unmistakably the starting price the moment trading reopened next week.
What was even more shocking?
Even though it was the weekend and the market was definitely closed,
the position of that dot was still wiggling up and down ever so slightly, reflecting all kinds of real-time macro conditions, commodity prices, and overseas market indexes.
On top of that, the one mystery I’d been wondering about from the beginning was finally solved.
*I didn’t even need my own phone.*
Whenever the aftertaste hit me, whether it was my phone or someone else’s, I could see the future of the chart.
I’d just discovered another limitation of my ability, and the corners of my mouth curled up with pure delight.
“Sohyun, let me see the Bitcoin chart this time.”
“…Okay.”
Sohyun still looked at me with that weird expression, but she obediently moved her fingers and brought up the Bitcoin chart right in front of me.
“Here you go.”
My eyes lit up and I stared at the screen.
But it was strange.
Unlike the blue-chip chart I’d just seen, there was no line showing the future or a red dot for the starting price on the Bitcoin chart.
Just a completely normal, real-time chart that kept ticking even on the weekend.
*What the… why isn’t it working?*
I looked up at Sohyun in confusion and kept talking.
“Sohyun, click on any other altcoin for me. Dogecoin or Ripple or whatever!”
Sohyun sighed, tapped the screen a few times, and showed me the Ripple and Dogecoin charts in turn.
The result was exactly the same.
Not a single trace, not even a red dot.
“Then try bonds this time! Turn on the US 10-year Treasury note chart! And commodities like gold or oil!!”
“Haa…”
A shallow sigh finally slipped out of Sohyun’s mouth.
She wasn’t just doing the laundry anymore. Now she was the one who had to shuttle me charts of every financial product.
But still, she flipped through the apps without a single complaint and showed me the bond and commodity charts in order.
After I checked every single chart Sohyun showed me one by one,
the bonds, gold, oil… not a single chart showed the future trajectory.
Only the **stock** charts were working.
My amazing ability that the aftertaste had given me could perfectly read the future of the stock market, but not the other speculative markets like coins or commodities.
…
…
…
“Ah… damn, that’s so frustrating.”
A deep sigh escaped me when I realized the ability only worked on stocks during the weekend when the market was closed.
If the aftertaste had kicked in twenty-four hours a day in the constantly moving coin market,
I could have scraped up money the entire 365 days without stopping…
The fact that I couldn’t make the profits explode even more felt bone-deep painful.
While that was going through my head.
The special sensation right after I came that cleared my mind and drew the future of the charts slowly began to fade.
The aftertaste’s steady 20-minute hold time had finally ended.
Right at that moment.
Thud-thud-thud, ding-ding-ding
A cheerful washing-machine sound rang out from the corner of the studio.
Sohyun, standing near the sink, casually walked over to the washing machine.
She bent forward at the waist to take out the laundry, reaching her arm deep inside.
And at that exact second.
“!!!”
My eyes snapped open wide even though I was lying on the bed, the regret still burning in my chest.
Because her back was bent so deeply,
the jeans she was wearing were stretched tight, swelling like they were about to burst.
Thanks to that,
the delicious curve of Sohyun’s plump ass that was visible through the tight denim fabric,
the soft, puffy inner thigh meat that looked like it would feel so squishy if I touched it,
and the heavy, thick silhouette of her plump, juicy ass cheeks that bulged out even more visibly from between her legs…
It was far too naked.
The fertile lower-body line unique to a married woman who had already given birth carried an overwhelming destructive power…
*Goddamn…*
My cock, which had just finished cumming, was more than enough to get hard again.
At the same time.
Separately from the pure lust surging inside me,
a lightning-fast thought about the aftertaste flashed through my mind.
So far the only thing I’d ever made her do with me was give me a blowjob…
What if I grabbed that delicious ass and actually had real **sex**?
The real aftertaste for a man didn’t come from sucking with the mouth. It came when I pumped every drop of cum deep inside a woman’s pussy.
If I actually had sex with Sohyun and came inside her,
wouldn’t the 20-minute fixed duration of the aftertaste suddenly jump to 30 minutes or even 1 hour?
Or would the very effect of the aftertaste itself change to an entirely different level?
The questions kept piling on each other,
and my lust and calculation engine inside me started spinning wildly.
There was only one way to solve all of this at once.
I would just have sex with Sohyun right now.
The moment that thought hit me,
I couldn’t refuse the sudden urge to just try it anyway.
After all, I was paying 600,000 won for this nursing job. If she said no, too bad.
So in the next moment,
I waved my hand holding the braces and, carrying the laundry basket with the other, called out to Sohyun who had just straightened up.
“Sohyun. Let’s have sex.”
“!!!”
Sohyun’s body, which had just turned, jerked and froze in place.
“Wh-what did you just say?”
Then she slowly turned her head toward me and spoke.
Sohyun’s face, which had been blank since this morning, twisted into something ugly and twisted beyond recognition.
This morning.
Except when I’d pulled her pants down and made her shit in front of me,
or when she’d called me 600,000 won just to wipe my ass,
or whenever I made any other demands,
or even when I held my cock so she could pee and then gave me a blowjob,
she had kept a completely expressionless face like she was in a trance.
But the single word “sex” that had just come out of my mouth had turned her into the most terrifyingly scary expression I had ever seen.
Of course I knew she was doing it because she was desperate for money…
In that moment, pure instinct kicked in and I started to feel afraid.
Even beyond just making her shit openly in the bathroom,
when she had to wipe my ass, I thought, *Is there really anyone this crazy?* My head was pounding with shock and disgust.
But after watching her struggle to hold a spoon with thick braces on both hands, or flail around because shampoo foam got in her eyes…
Something like a sliver of pity, or perhaps sympathy, began to sprout in the corner of my mind.
*She has no family, no friends, and here she is alone doing something this pathetic for 600,000 won… Poor thing.*
Thinking that I was basically raising one more child while I paid for the nursing,
I kept thinking the man’s slightly pathetic and helpless side looked oddly pitiful.
That was probably why.
Right after I made her pee, even though the man’s cock had instantly hardened and he asked to suck like always,
I felt no real disgust.
It was the thing I’d sucked for days now.
More importantly, today the feeling was a little different.
Unlike the man who had broken both hands and couldn’t do anything properly,
I was faced with a large, thick cock that was fully erect and filled her mouth the way she usually did.
While I sucked and swirled my tongue around it,
Sohyun oddly felt like she was playing with a huge toy that wasn’t even a penis.
Unlike her husband, who couldn’t even get hard no matter how much she sucked,
“Ugh… Sohyun, there… it feels so good.”
The man’s cock, which got rock-hard within ten seconds just from touching her mouth,
trembling all over with every stroke of her tongue as he showed how much pleasure he felt.
It was so heavenly that an odd sense of pride even appeared.
Besides, the time I sucked his cock was only about ten minutes at most.
While giving nursing care for less than nine hours and just sucking the cock for a few minutes, I was already being paid 600,000 won per day.
I thought this was the easiest and most efficient way to save money for Su-a’s hospital bills.
So Sohyun was quietly adapting to this weird relationship and situation.
But the moment I heard the voice from behind her, “Sohyun. Let’s have sex.”
Even that tiny bit of sympathy I had for the man completely shattered.
*How low does he think of me?*
It was true that I was in an absurd situation where I had to suck the man’s cock and do nursing care for money, even though I already had a husband and a child.
But no matter how absurd it was, I couldn’t just have meaningless sex.
The empty, foolish reason behind it had drained every drop of my remaining dignity.
So I wanted to immediately spit curses at that disgusting human being, run out of this pathetic room, and never come back.
But I couldn’t curse, and I couldn’t even move my feet.
I simply couldn’t give up the money I was receiving right now.
