I Think I'm Really Gonna Cum—!!
"Kyaa, kyaaah!" My 'sister's' thighs clenched tight. She squeezed my face between them, the soft flesh warm and pressing down with insistent force. "Haaah…"
On top of that came the scent of her juices rising from her slit. "Ah, that's—stop!" I pushed my head forward with force. My 'sister' struggled with everything she had, trying to keep me out. "P-Please…! I said stop, stop it already…!"
Her soft pubic hair tickled my nose. My scalp stung from her yanking at my hair, but I didn't care. "Mmm, slurp… lick-lick, chuup!"
"Aaaang—!!" The flesh trembling against my tongue was beyond words. It wasn't just soft or yielding—it felt like it might melt away at any moment. I pushed my tongue firmly between those folds, feeling the slick inner walls as they pulsed and gushed more fluid. "Slurp-slurp… chup, chuup."
"Ah, seriously, that's so dirty!" She used to shove her pussy in my face while I slept, but now she was the one screaming that it was filthy and demanding I back off. "Hnn… lick-lick, slurp."
I ignored her, burying my face even deeper and stretching my tongue as far as it would go, stirring inside her hole. "Hnnng! Haah, haaaah—!" Her moans made my lower body twitch on its own. Her slender waist trembled violently, goosebumps rising across her skin.
I slid my hands up from her waist to her breasts while my tongue kept working. "Aaaang!" A sharp cry burst out, her body twisting and writhing as it clamped around me. Then came a sudden psssht as she sprayed my face, followed by several more spasms before she collapsed limply onto the bed.
"Haah, haaah…! Hnn, hnn!" Right in front of my eyes, her pussy twitched and fluttered, still leaking steadily. Between the thin strands of hair, her clit—previously hidden under its hood—had swollen enough to peek out.
"…Kiss." "Kyaa, kyaaaang—!" That tiny nub was impossibly soft. Even while sucking and licking it, it felt like it would dissolve on my tongue. Like cotton candy. The sweetness spreading through my mouth really did remind me of it. I started rolling my tongue wildly, sucking like it was candy. "Nngh! Uu, uuugh?!"
The clit quivered against my tongue. I felt an overwhelming urge to nibble and chew on that sensitive spot. "Kyaaah?!" I didn't hesitate. I acted on the impulse at once. At the same moment, dull impacts hammered against my head. Thud—thud—thud— "Ah, agh…"
The sudden punches startled me. Of course, they came from my 'sister'. "Yaaah—!! Have you lost your mind!?" Her voice was thick with emotion, and the punches kept coming. Thud—! Thud—! "Ah, aaah…"
They actually hurt. I might have backed off, but instead I doubled down, sucking and nibbling her clit with everything I had. "Yaaaah!!" Her exposed clit twitched, her hole still spurting. Her resistance faltered, then she went limp again, panting roughly. "Haah, haaaah…! Haa, hnn… I-I messed up…! So please, that…! Stop, stop—!!"
Her desperate plea only made me more determined. I sucked and pulled at her clit with all my strength. "I-I'm really, really gonna cum—!!" she screamed.
Cum? Whatever she meant by that didn't matter. All I could think about was making her do it. "Slurp-slurp-slurp… chup! Lick-lick, chuup…!" Her thighs clamped tighter, fingers digging into my hair. "Nngh, nngh! I told you to stop—!!"
Her thighs squeezed my face hard. Hot fluid sprayed across it, and just as I thought I'd finally done it— "Ah…"
I'd endured the punches, but this time instinct took over. I jerked my head back. Shhhhhhh— A long, powerful stream shot out from between her spread legs, glittering in the light. It arced through the air and soaked the bed while my 'sister' bucked and convulsed. "Hnnk! Haah, haaaang…!"
The muscles in her inner thighs quivered. She clawed at the sheets, body shaking. The violent tremors gradually faded, the stream shrinking until it stopped. "Hnn, hnnn…"
Her eyes were brimming with tears. She sniffled, then rolled halfway over with a groan. "Hic, hnn… I told you to stop… I said stop…"
She buried her face in the bed, mumbling. Her ass still trembled occasionally, her twitching pussy visible between her cheeks. "……It's fine."
"…Yaaah!! It's not fine at all!!" She sounded sulky one second, then raised her voice the next. "…Really, it's fine." "Ah, just get lost!"
Annoyed, she kicked her legs in the air. I waited quietly for her to calm down. "Haaah, hoo… haaah…"
Her breathing stayed ragged. It didn't seem like she needed to be this upset, so I tried again. "…It's really okay. It's not like this is the first time I've seen it. If I'm fine with it, what's the problem?"
My words were well-intentioned—and true. Smack—! I meant to give her ass a light pat, but ended up splashing the juices coating it everywhere. The awkward silence that followed made me swallow hard. "…Hey, Eun-yeong?"
I tried using her name to sound friendly, but her shoulders started shaking ominously. "…Uwaaaah!!" A miserable wail burst out. She cried so hard I had no choice but to shut up. "……You okay?" "Hic! Hnn! It's embarrassing! I'm so embarrassed I could die…!"
Comforting her only made it worse. Every time I spoke, she sobbed harder.

The room was filled only with the sound of the TV. The shower had stopped long ago, yet my 'sister' still hadn't come out of the bathroom. "Sniff, sniff."
Her scent filled the small space. My lower body was still rock hard from it. The mood being what it was, though… I hadn't been able to finish earlier, and the frustration was intense. Masturbating alone felt wrong now that I'd gotten so used to her. Even while idly stroking myself, my eyes kept drifting toward the bathroom. "……I should've cum earlier…"
Of course, going down on her had been plenty satisfying, but still—unsatisfied was unsatisfied. If she came out, I planned to coax and seduce her into letting me finish. "Haaah…"
I was fine, but she seemed overwhelmed by embarrassment. "…Ah!" This wasn't the time to space out. I started jotting down everything that had happened yesterday and today—every sensation—before I forgot. "Uh… what were her moans like again…?"
Turning sounds and movements into onomatopoeia wasn't easy. No matter how vivid the real noises had been, writing them down always felt a little off. I had to pick more impactful words; literal transcription killed the unique flavor of erotic writing. "…Still, the part where she tried to hold it in was the hottest…"
The way she'd grit her teeth and let tiny moans slip through her lips had been incredibly satisfying. I'd thought my dick was going to explode. "…Maybe I should ask if I can record her next time…"
Video was probably pushing it, but audio might be acceptable. "Haaah… I'm so fucking turned on."
Everything that had happened yesterday and just now still felt like a dream. But it was too vivid to be a dream—and the naked 'sister' was right there in the bathroom. I filled the blank memo with every detail of her movements, moans, and reactions, marking the parts that had excited me most. With my eyes closed, I replayed the sensations in my mind.
Vrrr— vrrr— A small vibration started in my hand, interrupting my thoughts. "…Ah, who is it?"
Thanks to how cut off from society I'd been, calls were rare. I checked the screen irritably. "Ah…"
It was an unsaved number, but the last digits looked familiar. I knew exactly who it was. "Haaah…"
My breath caught. I didn't have the nerve to answer. I just stared at the screen. Vrrr— vrrr— vrrr— The vibration made my palm tingle until it finally showed a missed call. "Hoo…"
Then a longer vibration came through. The screen lit up again.
"Haaah…"
My sigh deepened. I didn't have the courage to call back. I just turned the phone off. She said this week… I didn't think it would be today. "Haaah…"
I let out a heavy sigh, wishing the ground would just swallow me up. Anything would be better than facing her right now.
