The Younger Sister I've Never Seen Before (1)
I open my eyes on the bed in an empty room. I should be used to this daily sight, facing it without parents. …Or so I thought.
Rustle. Rustle. Something squirms beneath the blanket, and the sensation reaches me. My thoughts freeze for an instant. Fear creeps in. The fear that has haunted me relentlessly since my parents died. A vague terror I can never grow accustomed to, no matter how many times I face it. I'm not prepared. I've only just woken up; there's no time to brace myself.
The rustling doesn't stop. If anything, it grows louder. Rustle. Rustle. Rustle. Rustle. Rustle. Rustle. It won't cease until I pull the blanket away. With trembling hands, I grip the edge and yank it back violently.
Whoosh! But the sight that greets me is far beyond anything I could have imagined.
My "younger sister" is clutching my cock—swollen to the brink from morning arousal—and vigorously stroking it while rubbing her cheek against it. Thwack-thwack-thwack—thwack-thwack… Each motion sends strands of precum splattering, soaking the surrounding hair in a sticky sheen.
Younger sister. Younger sister? My memories glitch like static. Younger sister? Of course I remember her. Naturally. It's been over half a year since our parents passed, and we've been relying on each other ever since. After clearing away every trace of the deceased, the house and rooms felt hollow and desolate. The sink that terrifies me, Mom and Dad's room, the cold furniture that carries no human warmth—yet in that space, my younger sister always greets me with warmth. I do have a younger sister. A precious gem I'd gladly trade my life for.
But the figure before me, sweat-slicked hands pumping my shaft back and forth while pressing her doll-like, pale and soft cheek against it, feels nothing like the sister in my memories. I recall the long hair reaching her back. But was my sister's hair green? Have I ever seen green hair in Korea? The inner color of her slightly tousled green locks matches her cat-like, vivid yellow eyes. Her pupils, faintly narrowed in the dim light, also resemble a cat's. She tilts her small face—small enough to be covered entirely by my cock—from side to side. With each movement, not just her cheeks but her sharp nose and her plump, glossy red lips—coated in lip balm—come into view. Droplets of saliva occasionally fall from those lips, brushing against my engorged member.
Ah, our eyes meet. Her breath grazes my cock, dripping with precum—or rather, pre-ejaculate. Perhaps from witnessing the scene of pleasure with my own eyes, my thoughts momentarily paralyze as if struck by electricity.
"Good morning, Oppa~ Did you sleep well?" Her voice is high and clear. There's no doubt. This is my younger sister. When she was younger, she used to speak more politely. After entering higher grades, she adopted a rougher, almost delinquent tone. Even so, her inherent warmth hasn't faded, though she occasionally blurts out cheeky remarks without thinking. Her attitude toward me, her older brother, remains unchanged, but for someone who remembers her as a young girl, it's a bit disappointing.
I must not have been fully awake. As pleasure surges through my core and overtakes my mind, my thoughts finally sharpen.
"Uh… What time is it?"
"Hmm~ Around ten? I left my phone in my room, hehe."
I bolt upright. "T-T-T-Ten??? Shit, I'm late!!"
My sister doesn't flinch at my panic. She keeps her face close to my cock, her hand still busy. She's been stroking me nonstop throughout our conversation.
"Pfft, you dummy. It's the weekend today."
Tension drains from me in an instant. "Oh. Haah… I thought… I almost passed out."
Mocking her foolish brother, she continues pumping with her small hand. "If you were late, I'd have woken you up, obviously~ Have I ever failed to wake you?"
She's right. Waking me in the morning has always been her responsibility. Thwack-thwack-thwack-thwack…
"…That aside. What, ngh, are you doing? Since earlier…?"
Perhaps because my tension has eased, my body—already vulnerable to pleasure—trembles as her slightly grown nails graze the glans.
"Huh? Doing what?" She deliberately draws out her words. Her face is the picture of innocent confusion. Squelch… squelch… By now, not just precum but thick, semen-like fluid coats my entire shaft. With a languid tone as if she has no idea, yet her eager hands reveal the joy of having found the spot that pleases me, she half-closes her bright eyes and speaks.
"What do you mean, ngh. That, that thing, hngh, the stroking…"
She stares straight at my face and asks again. "What is that? Hmm~? You have to tell me so I'll know~"
Slap, slap, slap-slap-slap. Sounds I've never heard while masturbating alone echo from below. It seems her sweat and my fluids have mingled into a harmony. Her smile and movements show no sign of fading; if anything, they grow more frantic.
"Ngh… Ahk."
"What is it, Oppa? What are you stroking that feels so good~"
"M-My cock! Why the hell are you stroking someone else's cock first thing in the morning?!"
I blurt it out in one breath, struggling not to succumb to the pleasure. Hearing me, she snorts but never stops her hand.
"You told me last night in the shower. Don't you remember? You asked me to help you masturbate."
Ah, I think I remember. It seems we showered together as usual last night. I must have been confused because it was morning. Even so, isn't this far too strange? Do ordinary siblings openly request and provide such intimate handjobs…? But with her fingers poking at the balls beneath my shaft and rubbing the column between her index finger and thumb, I lack the strength to pursue the thought further.
"E-Even so, ngh, first thing in the morning…"
"Ehehe, who was the one standing at full mast when I came to wake you~"
My sister never backs down. More pressing is the problem: I haven't even fully removed the blanket covering us, yet I'm already nearing climax. This sensation of semen bubbling inside my balls. The way it throbs each time her slender fingers brush against it. Whether from the thrill of using someone else's hand instead of my own, I feel I'll finish much faster than usual.
"Hey. Hey. Wait, stop for a second."
"Hmm~? Why? Are you about to cum?"
Squelch, squelch, squelch-squelch-squelch…
"Y-Yeah. I think I'm gonna cum. It'll get on the blanket. At this rate—"
Panicking, I tense my swollen glans in a desperate attempt to hold back. But it seems I can't overpower my sister. Not content with up and down, she grips my cock and shakes it vigorously side to side. Then she opens her small mouth wide, lets out a "Behh~," and drips a few drops of saliva onto my shaft, making it sticky. My cock, already taut from her relentless stroking, shudders at the cool touch of her saliva.
"Ugh. What, what are you doing? The blanket will get dirty."
"Hehe, it's so cute♡ I'm taking extra care so your handjob feels good. It's fine. You can cum as much as you want♡ I'll do the laundry. Don't worry, just shoot your load?"
That was the limit. Her urging and her gentle, affectionate words melt into my ears.
"Ah—I really can't hold it. Right? See? I can hear your balls gurgling♡"
Squelch, squelch, squelch, squelch, squelch. Her piston-like motions come in short, relentless bursts, a rhythm entirely different from my own hand—urgent, demanding I expel everything inside without holding back. I have no strength left to answer. Normally I could delay climax long enough to question my own stamina, but this unexpected situation and the unprecedented pleasure crashing over me all at once leave me no room to resist. I feel the tip of my cock trembling. Each time my sister's excited breath touches my sticky shaft, it cools, only for her slender hand to heat it up again with frantic strokes.
"I'm… I'm gonna cum. Cumming… cumming…"
Slap, slap, slap, slap, slap, slap.
"Yeah, yeah, so adorable♡ Shoot lots of cum for me? Thanks for holding back on masturbating♡ Cum so much that it fills your little sister's hand, so much that it gets all sticky on my face, okay, Oppa?"
Her words become the signal. Spurt——spuuuurt——— Spurt—spurt—! The moment her encouragement ends, thick semen brimming with heat erupts from deep within my balls, surging up the urethra and shooting out like lava. My cock, which had been rigidly erect, suddenly loses strength and collapses, twitching, while the doubts I'd suppressed amid the pleasure resurface.
Who the hell is this? This thing forcing me into pleasure I've never experienced before—this is clearly, absolutely not my younger sister.
