The Side Effects of the Hand of God
I thought to myself, ‘So that’s why the tip suggested using it alongside the Sex Eyes…’
The Sex Eyes could pierce through a partner’s lust aura, but it couldn’t detect my own. That had just changed. The moment I activated the Hand of God, the lust aura that seeped from my hand and gathered into a tennis-ball-sized mass became crystal clear in my vision.
I focused intently, wrapping the lust aura around my hand like a glove, then slowly reached toward my sister’s crotch.
Swish. Touch.
“Ugh…!”
I placed my hand on her thigh—those artistically sculpted muscles that split so perfectly—and gradually tightened my grip. It felt more like a gentle muscle massage than foreplay, yet a short moan still escaped her lips. Her expression twisted in surprise, as if she hadn’t expected to moan at all.
Of course, to me that was the best possible sign.
I continued to stroke her thigh with light, teasing touches. It wasn’t the blatant, vulgar groping of a subway pervert; it was closer to the warm, loving way a grandfather might caress his granddaughter’s leg. There was nothing overtly sexual about the contact, yet Sieun-noona looked deeply flustered.
“Hngh… haa… what the hell… mmm… this kind of thing… ahh…”
Since this was an experiment to test bodily sensitivity, communication was a luxury. I completely ignored her increasingly intense reactions and moved on to the next stage.
If touching a non-vital area had produced this kind of response, I was dying to see what would happen when I touched her most sensitive spot. And according to the Sex Eyes, her current critical point was her clitoris.
Pinch.
The instant I used the Hand of God to lightly pinch her clit, a massive burst of lust aura exploded from it like dropping Mentos into cola. At the same time, a fountain of juices gushed from her pussy.
“Haa… ugh!!!”
Splash— Splurt—
I smirked darkly as I watched her squirt from the critical hit on her clit. Seeing a genuine queen-type like Sieun-noona crumble from a single touch of my hand sent a spine-tingling thrill through me.
“You were so confident earlier… and now you’re squirting all over the place?”
“Hnnngh… haa… I don’t know… you… what the hell are you…”
“You should’ve trusted me. I told you I have a talent for sex. A heaven-sent talent, at that.”
“That’s impossible! This kind of thing can’t be—hiiit!!!”
When she started spouting nonsense, I hooked my fingers and rubbed her clit up and down. The effect was dramatic. She shot out another powerful jet of pussy juice. I kept rubbing without pause, and she rolled her eyes halfway back, completely lost in the pleasure of the clit handjob I was giving her.
“Hngh… haa… hnn… hnguu…”
She must have gone insane from the constant clit stimulation—drool was now pouring from Sieun-noona’s mouth. I caught the dripping saliva with my fingers and fed it back into her mouth, then used my index and middle fingers to plug it shut so she couldn’t drool anymore.
I didn’t forget to activate the Hand of God the moment my fingers entered her mouth.
“Hnguuu!! Ugeuu!! Hngh!!!”
Squelch, squelch, squelch.
While continuing to rub her clit, I mercilessly toyed with her tongue using my two fingers. The pleasure exploding from her mouth must have felt incredible, because her screams grew even sharper. Not that they could escape properly with my fingers blocking the way.
Sluuuuurp.
After tormenting her enough, I finally pulled my fingers out. Thick, viscous saliva stretched from them like taffy.
“Heuuu… hng… kuhng… stop it…”
“Hmm? Stop what?”
“Just… hngh… stop… if you keep going… hng… something… feels wrong…”
“…Ah, was I too rough? I’m sorry, noona.”
I stopped the master play and pretended to comfort the confused woman, gently stroking her head. There was something I wanted to test. The idea had come to me suddenly, but I felt like I absolutely had to try it.
‘What would happen if I stroked her head with the Hand of God wrapped in lust aura…? Would it fill her mind with nothing but sex?’
My heart pounded with intense curiosity. If this worked, the Hand of God would truly be a god-tier ability. It might not work on just anyone, but for those it did affect, it meant I could turn them into living toilets whenever I wanted.
Swish. Sliiide.
Worried about damaging her brain, I reduced the amount of lust aura in my hand to less than half before carefully stroking her head. Then I met Sieun-noona’s eyes, which were now glistening with tears.
But whether viewed with the naked eye or the Sex Eyes, there was no noticeable change in her condition. The only thing happening was the lust aura around her head flickering on and off like a car’s turn signal. That was it.
Swish. Sliiide.
Thinking maybe the amount was too low, I increased the lust aura a little and stroked her head a few more times. Still nothing. It seemed the aura wasn’t penetrating into the brain just from stroking the head.
Well, of course. This wasn’t some hentai plot.
“…Minjun. Noona was wrong, so please unlock these. I’m really struggling here.”
She must have calmed down a bit from my touch. The heated moans she’d been letting out gradually stopped, and she spoke to me in a completely drained, exhausted voice. She sounded so weak it was almost pitiful just to hear her.
Wait, was getting a little fingered really that exhausting? Even with the Hand of God…
“Was it really that hard on you, noona?”
“Yeah… I almost lost my mind. Minjun, you really must be a sex genius… Every time you touch me, it feels so weird. My whole body goes limp…”
“Well, that’s too bad, but there’s nothing I can do about it.”
I shrugged. If she was this worn out, forcing the handcuff play would only tank her favorability. Besides, I had a rough idea of how strong the Hand of God’s effects were now. My main objective had already been achieved.
I got up from the bed, grabbed the key, and was about to unlock her handcuffs when the still-active Sex Eyes caught a suspicious flow of energy.
‘…What the hell?’
The shape of her lust aura was almost the same. She still had a consistent layer of it wrapped around her entire body. But looking closer, something was different. The shape hadn’t warped, but the edges were vibrating like crazy. It was vibrating so fast that you’d miss it unless you looked carefully.
The movement reminded me of the surface of a calm sea trembling after a major earthquake.
And the lust aura around her head that had been flickering this entire time was also far from normal. If injecting lust aura into her head had no special effect, there was no reason for it to keep flickering like that for so long.
“…”
“What’s wrong, Minjun? I told you to unlock these, didn’t I?”
It felt like a massive nail had been driven through my brain. The sensation was eerie. Even though she sounded exhausted, something about her voice felt off—enough to send chills crawling all over my skin. But I pretended to be completely calm, as if I hadn’t noticed anything.
I was already halfway onto the bed to unlock her cuffs, which put me in a dangerous position. Only her hands were bound; her legs were free. If a physical monster like her went berserk, she might be able to overpower me with just her legs.
“What will you do if I unlock these, noona?”
“…What kind of question is that? We’re going to have sex, obviously~ Noona’s so horny right now she’s losing her mind.”
Her answer came half a second late. To me, who had been waiting for her mouth to open, that tiny delay felt unbearably long. Just moments ago she’d said her body felt strange and weak, and now she was claiming she was dying to get fucked. It was extremely suspicious.
It was too faint to pinpoint exactly, but a strange current was definitely flowing between us. And it wasn’t the erotic, playful atmosphere our conversation suggested. It felt more like horror or a suspense thriller.
Still, I asked as casually as if this were just another ordinary day.
“Aww~ We can have sex without unlocking them. I can just fuck you like this.”
“Ughhh~ Why are you being like this? The handcuffs are hurting my wrists, okay? Hmm? Please unlock them~~”
“You know those are costume props and don’t hurt at all… I wore them all day yesterday…”
“…Oh, right. You did. Um… Then how about I give you a handjob if you unlock me?”
“Why do you keep asking to be let go? We agreed on one hour, remember?”
“You’re not going to unlock them? Why? Why won’t you unlock them? Please, just unlock them already?”
“Why do you want them off so badly? Tell me the reason first. You said you liked being tied up earlier.”
“It’s hard. I’m struggling, okay? I’m going crazy from how hard it is, so unlock them right now. Please. Unlock them. Hmm? Minjun, this is noona’s wish. Please.”
This wasn’t the usual Cha Sieun—always relaxed and playful, who would instantly turn into a femdom queen the moment she flipped a switch. The woman in front of me showed no trace of composure, playfulness, or queenly dignity.
The more I dragged out the conversation instead of unlocking her, the more violently her pupils shook and the stranger her voice became. She was even biting her lip now, and her once-normal expression was gradually falling apart.
“Unlock them… hurry… I think I’m going to lose it… please unlock them…”
She was acting like someone whose mind was extremely unstable—restless and desperate. Even though our relationship was still new, I knew Cha Sieun wasn’t normally like this. Something had definitely changed in her, and it was probably because I had stroked her head while infusing it with lust aura.
That was the only trigger that made sense. It was my fault for recklessly using the Hand of God on her head without knowing what kind of change it might cause, but this situation was still relatively lucky. Since her hands were bound, even a physical monster like her had limited options. That must be why she kept begging me to free her hands.
I slowly prepared to scoot my body backward without being obvious and spoke to her in a low voice.
“Noona… should I unlock the handcuffs?”
“Yes. Unlock them. Please unlock them.”
“No thanks. You look way hornier when you’re tied up.”
The moment I said it teasingly, her crumbling expression turned ice-cold. The pupils that had been trembling as they looked at me suddenly shrank to pinpricks, like a starving beast locking onto its prey. It was like a bomb exploding the instant its fuse burned out—I could tell whatever was inside her was about to burst.
“Unlock this. This is your final warning…”
“You know your eyes look really fucked up right now, right?”
Whoosh.
Suddenly, I heard the sound of wind rushing past my ear. The instant I heard it, I urgently rolled backward and fell off the bed. When I looked up, sure enough, Sieun-noona had used the force of her own bound arms to kick her legs up with terrifying power. Her body was folded in half. From the posture, it looked like she had tried to trap me between her raised legs.
No—judging by the murderous force behind it, she probably planned to choke my neck with her feet and force me to unlock the cuffs.
‘If I’d been even a little slower, I would’ve been caught… Fuck, that was scary.’
As expected, Sieun-noona was far too dangerous for a weak guy like me.
Clank clank clank clank—
“Unlock it!! Unlock this right now!!! Unlock it before I cut your dick off!! You slave bastard! How dare a mere slave treat his owner like this?! You’re my slave!! Do you understand?!!!”
She flipped her body upright and began thrashing around like a madwoman. There was no longer any attempt to hide it. I wondered what she had been hiding so desperately all this time, but seeing this side of her, I could understand why.
My heart pounded at the terrifying sight, but since I had caused this situation, I couldn’t just sit there in fear. Even though I hadn’t intended for this to happen, now that it had, I needed to calmly analyze the side effects of the Hand of God and find a way to deal with them.
Scraaape.
I pulled out a chair, placed it beside the bed, and sat down. Instead of unlocking her, I sat there watching like a spectator. That made her go even more berserk.
“I’m going to pinch your nipples and rip them off!! I’m going to crush your dick with my foot!! How dare a cocky slave bastard tie me up!!! How dare you!!!”
“Noona, calm down for a second.”
“You son of a bitch!! I’m going to keep you tied up for the rest of your life and torment you!! I’ll make you wag your tail like a dog and bark for me every day!!! You’re mine!! You’re mine!!! And yet… and yet how… how could you do this to meeeeeee!!!”
“Lower your voice. You’ll hurt your throat.”
“Shut up!! Don’t speak without my permission!! You can’t even breathe without my permission, you can’t drink water without my permission… The only things you’re allowed to drink are my spit and my piss!! You’re mine forever!! Live for me and then die for me. Die panting like a dog underneath me…!! You’re mine… you’re mine!!!!”
It gave me goosebumps, but not out of fear. The way she rolled her eyes, swallowed by madness, screaming like a lunatic—it resembled the true nature I kept hidden deep inside, and that was what made my skin crawl.
‘Could this be…?’
