My Head Went Cold the Instant I Heard Shin Sarang's Name
"H-haah! Hurry, cum, hurryyy!!"
Slap-slap-slap—!
The thick, massive foreign sensation filled my belly. The shape of the cock that fit so perfectly against the walls of my cunt—tightened from the excitement—every ridge, every bulging vein, transmitted itself straight through my inner walls.
And I could see that bitch Areum thrashing beneath me.
I wrapped my arms around her as she twisted and writhed under me. The difference in our builds meant I was the one being held, but that hardly mattered. I pressed my big ass down so the place where we were joined wouldn't slip free, then coiled my legs around her like a snake.
"H-ngh! Keep... hah! Trying to run... stay still..."
"Th-this... fuck...!"
"Haah! Just cum already... then I'll get off, I-I will..."
The sweat running down my back told me just how hard and desperately I'd been working my hips. And now I just wanted this sex to end. It hurt. My waist, aching from all the up-and-down rocking, and the cock driving deep, spreading my soft insides open.
A strange feeling washed over me too. That cock buried deep in my belly kept twitching, scraping somewhere inside me over and over. I had to finish this. Any more sex was starting to scare me.
"Cum, Park Areum... cum alreadyyy!!"
No matter how I clenched, that bitch Areum just wouldn't finish. Insertion alone made my hips feel like they were about to give out, and I had to hold back the hot precum surging up my urethra—barely, truly barely managing it...
"Hiih! Haah, haaaah!!"
I squeezed my cunt again. The huge cock already filled me so completely there was barely any room left to tighten, yet I still clenched around that bitch Areum's cock, around my own hole. The only thought left in my head was to milk that cock with my pussy and take the load. Fill this belly, this womb, with cum—that was all I could think about.
Squelch—! Squish—! Squelch—! Squish—!
I stayed locked in that bitch Areum's arms and thrashed my hips like mad, bouncing without a shred of sense left.
(Park Areum)
No matter how hard I pushed, Shin Down wouldn't budge. No matter how I tried to peel her off, she just clung tightly on top of me and kept working her hips with everything she had.
Thanks to the orgasm right before we started, I managed to ride out the worst of it and hold on. Shin Down's body grew more and more limp, her movements slowing. But the way she clenched around me and begged me to cum already—craving a load while wearing my body—went way past awkward.
"I-I told you! To come out already!"
It hit me all at once. Naked, bodies stacked on top of each other, tangled together—and still a wave of shame rose up. It wasn't even our first time fucking like this. But watching Shin Down, in my body, actively grinding against me made it almost impossible to endure.
"Hnnnngh!!"
Maybe that was why my body hit the edge again so fast. In this state it felt like cum might even spill out of my mouth.
Squelch—! Squish—! Squelch—!
"I'm, ngh! Telling you one last, haah... time, come out... fuck..."
"Please, just, hah! Cum for me... i-inside...! Haaaang!"
I'd been holding back my strength, worried I might hurt her. But with creampie off the table right now, I was ready to use force if I had to.
"Hiih! Hnnngh!!"
Luckily, the tiny tremors starting in Shin Down's body grew stronger. The heartbeat that felt ready to burst from her chest pounded against me.
Spurt—! Spuuurt—!
The hot fluid soaking my lower half ran down my hips and soaked into the bed again. Her cunt clenched hard, massaging my cock, and I gritted my teeth, fighting the urge to finish.
"Hiih... you said you'd cum, haah... and yet, haaang..."
Collapsed against my chest, Shin Down muttered that while her breathing heaved. She still had enough strength left to fidget her hips back and forth, but when I shoved her sideways she toppled over with a soft slide.
"Haah, ha... haaah... so tired..."
Shin Down lay there like a frog, legs spread wide, panting hard to catch her breath. My eyes drifted to the red marks on those bouncing tits; she must have felt the stare, because she yanked the nearby blanket over her face and body.
"...I still haven't cum."
I showed her my cock, still glistening and wet with her juices.
"H-fuck... get lost..."
A thin, dying moan leaked out from under the blanket. The legs that had been spread wide pulled closed again.
"Why? You begged me to cum inside. Not going again? Not swapping back?"
"...I don't feel like it. Haah... I'm fucking exhausted right now, so please just... get the hell out..."
Shin Down's sharp reaction sparked a little irritation in me. I'd only done exactly what had been done to me. So what was this reaction supposed to be? Acting like she was the victim. I was the actual victim here—why was she the one acting more wronged?
"Hey. Look."
"...What."
"Just look, damn it."
Only after my threat did Shin Down peek out from the blanket.
"Not moving the blanket?"
"Haah... why do you keep..."
Trembling pupils, trembling voice. Like she'd been scared half to death. Why she never listened when I asked nicely would probably stay a lifelong mystery.
"Watch carefully."
I grabbed my cock again and gave it a few lazy up-and-down shakes. Slick fluid splattered everywhere, soaking the bed.
"I still haven't cum, okay? You're the one who jumped me. So if it ends like this, what the hell am I supposed to do?"
"Y-you... should've just cum earlier... you held back too, h-haah..."
My voice was pitifully shaky. Unfortunately, all it looked like to me was pathetic.
"Enough. Just spread your legs again. We're really out of time. Let me finish quick and get out of here."
"B-bullshit... you're just planning not to go inside again. Huh? You think I'll fall for it a second time?"
"...What the hell are you talking about, you idiot."
Telling her to spread her legs had been me being considerate. Just lie there quietly with them open—my kind little favor. Then I could fuck her as much as I wanted and be done, no trouble. That was all it would have taken. But Shin Down just had to make a scene.
"D-don't touch me. Even one finger and I'll scream for real. S-Sarang's outside, remember?"
The way she talked back made me think she had some kind of trump card. But all that came out of her mouth was Shin Sarang.

The moment I heard Shin Sarang's name, my head went ice-cold.
"Ha... funny. Then go ahead and scream once for me."
Ssshh—
My knees dragged across the blanket. I crawled forward slowly on them. Shin Down, looking conflicted, scooted backward little by little.
"What? Can't do it? Or should I just yell that I'm about to fuck 'Park Areum' at the top of my lungs?"
"Ah, ah..."
Something seemed to click; her face went blank and stupid. She wrapped the blanket tightly around herself, trying to cover her hole.
"I can just dump my load right here and switch back to normal, right? But what about you? You'll be the trash who raped me right in front of Shin Sarang."
"Hngh!"
I pressed firmly on her lower belly and watched that dazed expression twist.
"That what you want?"
"Ha, haha... are we really gonna keep doing this?"
"You started it."
"Y-yesterday too, fuck... I was just sleeping quietly... th-then you barged into my room, huh? And did all that, haaah..."
Funny enough, Shin Down really did look wronged. Of course, the fact that she only seemed to care about not looking disgusting in front of Shin Sarang just made her more nauseating.
"I asked you last time too. Okay? Let's really stop this, us."
The way she only showed this side when she was desperate or cornered made disgust rise in my throat.
"A-Areum... okay? You got it?"
She must have taken my silence for agreement, because she sat up and started coming closer.
"I'm sorry, I'm really sorry, so let's just stop for real now—ghk! Ghhk!"
I reached out and grabbed her throat. That soft, thin neck fit completely in one hand. A little more pressure and—though I'd never actually do it—I thought it might snap.
Thud! Thud!
"Ghhk! Keh, kehhek!"
She pounded on my body while coughing dryly. Tears ran down her face from the corners of her eyes. They caught the light and seemed to shine especially bright.
"Don't get cocky."
"Ghhk! Keh, kehhek!"
"Sorry? Really sorry? Again?"
"Shorry... I'm shorry, kehhek!"
My face was a mess of tears and snot. And once again came the endless stream of apologies whose sincerity I couldn't trust.
Knock-knock-knock—
Right then a knock thundered through the whole house like a clap of lightning. The only people home were this bastard, me, and Shin Sarang, so the one banging on the door from outside had to be her.
"Oppa? Unni?"
"Ghhk! Khh!"
"Quiet. No—do whatever you want."
I tossed Shin Down aside and climbed down from the bed. Then I gathered the clothes scattered on the floor. The cock that had been rock-hard just moments ago had already gone soft and drooped. So even with pants on, nothing showed.
"Wait!"
"Ah, coming!"
Thud-thud—
I left Shin Down like that and stepped outside.
Creeeak—
"What?"
"Ah..."
Shin Sarang looked startled at my face peeking through the crack in the door.
"Ah! Just now I got a message asking when we're leaving."
"From Auntie?"
"Ah, yes. It was Auntie."
Speaking in Shin Down's body made me flinch for a second, but luckily it seemed fine.
"We'll leave on time. But why'd she message you?"
"I wonder...? But, um, Unni? Still sleeping?"
"...Says she's a bit tired. Want to watch some drama for a bit? Eating at home later is fine, right?"
"Yes, that's fine."
"Got it. Go on."
"Yes..."
Had she sensed something? She looked a little suspicious, but without any further reply she headed back to the living room.
