The Frog That Flipped
I pin down the woman’s body as she thrashes like a frog flipped on its back. One hand clamps both her slender arms above her head while my weight presses down on the feet that had been shoving against my stomach. I seal her mouth—still trying to form words—with my own and keep working her clit with my free hand.
“Mmmph—! Hnnngh?!”
What reflects in Go-eun’s eyes is pure confusion, followed by pleasure slowly erasing her reason. In place of the lips I’ve silenced, her lower mouth spits out wet, squelching moans. Without giving her even a moment to think, I grind against the walls that keep clenching around me until her entire body suddenly goes rigid.
“Kuh… haaah…!♡ Oohh…!!”
“…Sorry. I’ll explain everything later, so for now… just leave it to me.”
“Choi… Choi Woo-joo…♡ Stop, you bastard… Ah, it’s not too late yet…♡”
Even while violent convulsions from her climax rip through her, Go-eun still tries to push me outside the line. To her, this moment must feel confusing, terrifying, and utterly hopeless. But I have no choice. The mere thought of Choi Go-eun becoming someone else’s slave fills me with unbearable disgust. My cousin, the girl I treated like a friend, my uncle’s daughter. If I don’t claim my family, someone else will steal her.
“Hey, are you even listening to me…?! Let go, I said let go—?!♡”
Her cunt, now soaked and gaping, is fully prepared to welcome a man. Her nipples stand flushed and stiff, and the corners of her mouth have unconsciously lifted. Even as she spits out denials with an expression that clearly looks forward to what’s coming, I yank my pants down and slap my sweat-slick cock onto her belly—right above her womb.
The instant I do, Go-eun’s gaze locks onto it like a sunflower chasing the sun, and her breathing grows noticeably rougher.
“What the… this size…? Kuh…♡”
Curiosity now floods the voice that had been full of refusal just moments ago. Forgetting to push me away, she unconsciously spreads her legs. While she stares at my cock and swallows her saliva, I reach out and drag my bag closer.
Ever since the pregnancy incident with Haemi-noona, I always carry condoms. Of course, to rewrite the characters on her, I need to turn Go-eun into my Fanatic. That means I have to pour my cum inside her body. So why the condom? The Saintesses use that absurd “Fertilization Nullification” method for contraception, but Go-eun is still an ordinary human woman. If she gets pregnant, there’ll be no turning back unless I make her a Saintess too.
Yeah. If she does get pregnant, I won’t be able to face my parents or my uncle. I’ve already crossed the line long ago, but that doesn’t mean I plan to be completely irresponsible. I slowly tear open a condom and roll it over my painfully swollen cock.
“Choi Woo-joo, are you really… really going to…? Haa, haa…♡”
Even without creampieing her, there’s still a way to turn Go-eun into a Fanatic. Just like how Yunsol fed my cum to Dohyeon-noona, all I have to do is make Go-eun swallow it.
“…Tell me if it hurts. I’ll go as slow as I can.”
“W-wait a second…! This is seriously not okay, you really— ngh, nngh…?!♡”
I move my hips with excruciating slowness, prying apart the tight, squeaking membranes. It’s insanely narrow. Even though I loosened her with my fingers first, the grip is still this intense…
“Aah! Hnngh?! I-I can’t breathe…”
“I’ve only got a third in. Just bear with it a little longer.”
“Haaah, haaah! Pull it out…!♡ My head, my head’s going crazy! Hiiit…!♡”
Despite her words, Go-eun’s face is lost in ecstasy. Her legs wrap around my waist, pulling me in, while her arms circle my back. I push harder, sinking the remaining half of my cock inside her.
“Ahe, hiit…! Ngh, it’s so deep… I hate thi—”
“Ugh?!”
Schlup—!
“Oohh♡”
It happened in an instant. While I was trying to match her pace and insert slowly, her struggles had grown more frantic the deeper I went. The moment Go-eun’s legs—still wrapped around my waist—moved on instinct, I slipped on the sheets. What followed was an enormous, wet impact.
The shock traveled up my cock, strong enough to feel it in her womb. All the air and mucus inside her pussy rushed out at once as my cock crushed straight into her cervix.
“Hey, Choi Go-eun?! Are you o—”
“………………”
A thin stream of drool leaks from her slightly parted lips. Her eyes are wide open in shock, but consciousness has already fled. From her loosened urethra, urine trickles out helplessly, soaking the bed beneath my stomach.
“…Fuck.”
Completely caught off guard, I scratch my head roughly and sit up. Go-eun’s eyes have lost all focus. It looks like it’ll take a while for her to wake up. I briefly consider using a forced command, but it doesn’t seem like a good idea. I’m not sure if it’s the effect of the characters, but right now her body is far too sensitive. Whether she passed out from the sudden pain of her womb being slammed or for some other reason…
Twitch. Jerk—
“…It’s clenching like crazy.”
Every time I slowly pull out and push back in, even just a little, her hips jump and spasm. Even unconscious, Go-eun’s body keeps cumming—violently. If I wake her with a command, she’ll probably faint again immediately from the overwhelming pleasure still echoing through her. And she’ll definitely start screaming “We can’t do this” and “Let me go” again… I don’t want to hear that either.
But if I don’t do this, my entire family’s lives will be destroyed.
Maybe it’d be better to just finish quickly while she’s unconscious? I move my hips slowly—
“Nngh… oohh…♡”
Jerk— Squirt—!♡
Nope. Every single thrust makes her squirt like a fountain. On top of this hot, humid weather, the windows are closed and I’m practically drowning in hot water. It’s driving me insane. Besides, my cock—already spoiled by the insane pleasure the Saintesses give me—won’t be satisfied with Go-eun’s pussy. Jerking off alone would probably take at least three hours, and even using her unconscious body would take over an hour.
There has to be a better way. A way for both me and Go-eun to finish quickly without either of us feeling awkward or embarrassed.
My head is pounding. How am I supposed to do this with the cousin I played with, slept over with, and fought with since we were kids…
“Ah.”
One idea flashes through my mind. Just like back then. Like when we were little. If I can recreate that everyday life we used to share—playing, sleeping, fighting—wouldn’t that work? If I can create a normal day where I face Go-eun like usual and we just mess around like always.
I pick up the mask that had rolled onto the floor and check the back. My ultimate goal is to rewrite the character engraved on Go-eun from Slave to Fanatic. Adding one more character right now shouldn’t be a problem. Just like Dasom-noona, the call girl who became a Fanatic even after receiving both Depravity and Modification.
“The ones I can read… besides Slave, Incineration, Depravity, and Modification, there are two or three more…”
Strange characters I’ve never learned before, yet their meanings gradually become clear. There seem to be well over three hundred characters written on the back of the mask, but this is still plenty. Fortunately, the one I need right now is readable.
When I press my finger against a character whose meaning I understand, it emits a low hum and glows with a jade light. After confirming the same character has appeared on the front of the mask and on my forehead, I press the mask onto Go-eun’s face.
The character written on her forehead is Modification. It will alter Go-eun’s common sense and perception. Every time the character on the mask fades, her body twitches and jumps. By the time those spasms gradually subside, the Modification that had floated on the mask has transferred to her forehead.
“Good. Then now…”
I remove the mask from her face and reach toward the shining character on her brow.
I stand in front of the door, brushing off my sweat-soaked shirt with one hand. Just like thirty minutes ago, I press the doorbell, shove my hands into my pockets, and wait. The doorbell is the trigger. It’s the bell that signals the beginning of everything I’ve set in motion.
I stand in the hallway for a moment, scanning the surroundings for any unexpected variables. Then, with a clear electronic chime, the door lock clicks open and a woman appears from behind it.
Choi Go-eun. My family and my friend.
“Oh, what’s up? What brings you here?”
“…I had something to do at school so I came out, but I missed the bus timing. It’s already the end of June but it feels like midsummer. I feel like I’m gonna die from the heat—can I come in for a bit?”
“Sure, whatever. Since when did you ever ask for permission to come in?”
Go-eun grins and playfully punches my chest, treating me with the same natural ease as always. As if she’s completely forgotten everything that just happened. As if this is the first time she’s seeing me today.
I follow her inside after she opens the front door and starts humming. The house is much cleaner than before, and the air conditioner is running, filling the room with cool air. I watch as Go-eun throws herself onto a freshly changed, fluffy blanket instead of the one soaked with urine.
“Then just rest and leave whenever~ I was finally enjoying some freedom for once.”
“Hah… If you have time for that, why don’t you go to supplementary classes? You barely prayed during midterms and still got an F—”
“Can you just leave right now? My mood is suddenly terrible.”
“I’m kidding. The F part was a joke you wouldn’t get anyway.”
“Fuck off.”
The same old jokes, the casual stream of playful curses. Go-eun lies on the bed kicking her feet while staring at a video playing on her phone. The moment I plop down heavily on the bed beside her head, the Modification takes effect.
“Ugh…”
With a small groan, Go-eun flops face-down across my lap and starts reading a webtoon. One hand scrolls down the screen while the other casually unzips my pants. It feels completely natural. So natural that I almost mistake this scene for something normal.
My cock springs out from between the zipper. Even with it right in front of her nose, Go-eun’s expression doesn’t change at all—
“Chuuup… slurp, mmm…”
Still focused on her webtoon, she takes my cock into her mouth and begins rolling her tongue around it.
“Hmm, it smells and tastes salty. Must be from all the sweat.”
“…Why, does it bother you?”
“No? I never said I disliked it. I actually like this kind of smell~”
Two characters sparkle on her forehead: Slave and Modification. It seems the settings I carefully engraved over the past thirty minutes are working perfectly.
‘Choi Woo-joo’s scent is pleasant. Among them, my favorite is the smell and taste of his cock.’
‘Family members don’t need to feel any distance. The standard for incest is creampie sex. Sucking cock or getting fucked by a cock wearing a condom is just stress relief.’
‘All of this is simply everyday life with Choi Woo-joo that has continued since we were children. There is nothing strange about it at all.’
‘The pleasure the body feels is completely separated from the mind. Even if my body cums like crazy, I feel nothing.’
“Ah, my jaw hurts. Hey, you got a condom? Let’s just have sex.”
