A Younger Sister I've Never Seen Before (2)
In the haze of heat born from pleasure, I sort through the thoughts rising one by one. First: I reached climax from a pleasure unlike anything I had ever felt. Second: No detailed memories of a "younger sister" surface in my mind. Just as the third thought begins to form, something cold touches my spent lower body and I jolt in surprise.
My "younger sister" is smiling, her hair and porcelain-white skin smeared thickly with the jelly-like clumps of my semen. "Ahaha! Oppa, how long were you holding it in? Look at all this. Huh?"
Whenever she opens her mouth, the traces of my fluids around her lips slowly disappear inside. Under normal circumstances, this would be an arousing sight. Yes, normally I would have surrendered completely to the pleasure without organizing these illogical thoughts. But I had never experienced anything like this before. I had certainly never felt the spine-tingling pleasure of my younger sister's slender fingers stroking my cock.
Even after ejaculating moments ago, my erection remains rigid. The pleasure she gave me belongs to an unknown kind I have never encountered. Therefore, the thing before my eyes is not my "younger sister."
If someone could peer into my mind, they would be horrified: "This insane incestuous bastard is regaining his senses from his little sister's finger touch!" Yet any healthy man knows exactly what kind of pleasure makes his cock respond and what fetishes stir his desire. That is why an unbearable chill runs down my spine. Something unknown is targeting me with perfect precision. I feel an indescribable terror—one that cannot be explained by simple post-orgasm emptiness. The hairs on my body stand on end. I am genuinely afraid of this self-proclaimed younger sister.
"Huh? Oppa, why aren't you saying anything? Post-nut clarity hitting you?"
I must stay calm. I cannot show fear. I cannot show suspicion. I have to pretend to act the way she wants.
"Uh, uh… It felt so good I thought my back would give out."
Half of that is true. The unfamiliar pleasure has left me struggling to form proper words. The "younger sister" laughs loudly, paying no attention to the semen covering her small face. "Ahaha. Cute~ Did it feel that good~? Hmm?"
She rubs her cum-smeared face against my cock. In memories that should not exist, I recall my usual sharp-tongued sister's expressions. The contrast with this affectionate version, happily nuzzling my cock and its fluids, is striking. The sight is so sensual it threatens to unravel my mind. The warnings I had built up for myself begin to fade like bubbles.
My cock, which had just dirtied her face, stands erect again without shame. "...Huh...?"
Even the usually smug sister looks somewhat flustered. While her fingers fidget with the hair around my shaft, she stares straight into my eyes. "...Not enough?"
"What?"
I answer reflexively, more startled than before. "You're asking if once isn't enough…? Yeah..."
She mutters in a shrinking voice while roughly wiping the fluids blocking her view with her tiny hand. To be honest, I have never lacked sexual desire—quite the opposite. If my memory is correct, I used to masturbate about three times a day on average. There is no way I could restrain myself in front of a beautiful woman who looks like my ideal type and confidently offers to satisfy me completely.
Dark desire overturns logical thought. Black lust bubbles up from my fingertips to my groin. Ah, maybe it does not matter after all. It is just masturbation, only with someone else's hand instead of my own. Yes. No matter whose body I borrow, masturbation is still masturbation. There is no need to be cautious.
I decide to be completely honest with my desire. With the endless lust that rises regardless of my will. "Yeah. It's not enough."
I say this to my "younger sister" while my cock twitches, dripping shiny precum. "Uh… Huh??? Eh?? Eh???"
The sister's earlier composure vanishes completely. I notice that when she gave me a handjob earlier, her face stayed pale despite her excitement, but now, faced with my cock demanding another release, it flushes bright red. "Eh…? Then… what… should I… do…?"
Even while stammering, her eyes—far more attractive than when she was showing off—reveal her eagerness to satisfy my desire. "I want to do the same thing again." "Eh? Handjob? Puhehe… Oppa, you really like my fingers~"
The sister seems convinced that her small, slender hand's skill at extracting precum has left me unable to think straight. "Yeah. But this time I want to cum in your mouth. That's fine, right?"
I state my desire plainly. Everything that had held me back until now is now secondary to lust. I want the same pleasure as before— no, something even more unrestrained—and thrust my twitching cock toward her face. "You can swallow my cum, can't you?"
I clearly hear her gulp. She must be imagining the semen that had dirtied her face and hands flowing down her throat. I feel an inexplicable heat against the top of my foot. Given our position, it must be her crotch. Ah. She is aroused. Just from that imagination.
There are no more brakes. I need to pour all my lust into this self-proclaimed sister and feel refreshed. That would be better for future countermeasures as well. Of course it would. I grab my cock with my previously idle hand and rub it forcefully against her dazed face. When the tip touches her moist lips, wetness seeps out from where it had been dry moments ago.
Her lips do not close completely, leaving a small gap where my glans brushes against her teeth. I slowly savor the contrast between the soft lips and the hard front teeth as I rub against them. "What are you doing. You have to help your oppa jerk off."
The sister can no longer hide her emotions. Her face shows clear bewilderment at the unexpected situation. She cannot refuse and only expresses surprise. And she has no idea that this only excites me more.
I push the tip of my glans slightly between her lips. If I ejaculate now, I could achieve the long-desired internal cumshot— or more crudely, a "mouthpie"—right away. But the sister intends to help me delay the pleasure a little longer. "Ahee… If you put it in… dehe…?"
Her previously closed mouth opens wide. The glossy texture of the entire oral cavity becomes vividly apparent, as if I am touching it with my hand. A bright red tongue, darker than her lips, extends long and flat. My cock, twitching with the urge to release on it immediately, settles onto that tongue. "Hand."
Instead of answering, her small hand quickly reaches out and grips my cock. Chilkeok, chilkeok, chilkeok—the foreskin, soaked with precum, makes sticky sounds as it slides up and down the shaft. The sister seems more confident than anyone at drawing out this kind of pleasure. The ecstasy from her tiny fingers and the flicking of her small tongue work in harmony rather than discord.
The sensation of five fingers rubbing my cock to hasten ejaculation and the tongue that sends shivers of pleasure each time it licks the hole combine toward the single goal of making me cum. Chyup, chyupchyup, chyooop—lick lick— The tongue play creates the illusion of entering a hole. Even though it stays only on the tongue, maintaining distance from both her pussy and throat, my cock twitches more frantically on that tongue than it would inside a tight pussy being filled with white fluid.
The sister deliberately makes gurgling sounds from deep in her throat to push my excitement to its peak. "Are you gonna cum? You can cum whenever… cum… cum in my mouth…♡"
Even with her slurred pronunciation, the meaning is clear. Of course I will cum. I will pour every last drop from my balls into her throat. Someone claiming to be a stranger's younger sister should be able to handle that much trouble, right? Yes. There is no need to feel guilty toward this woman. She is no different from an onahole I bought out of curiosity during my student days.
Without hesitation, I fill her pink oral cavity with thick white semen. "Ugh… It's coming… I'm cumming… Open wider..."
My tone has become commanding, unlike before. Fortunately, the sister responds fully to my wish. "Ehehe… Cum♡"
I do not want to hold back. I pour everything out until my mind goes blank. Gripping the shaft of my trembling cock, I press it firmly against her tongue and ejaculate. Byut—— Byuut—— Byuuut——!
The sister closes her slightly opened eyes and embraces my ejaculation as if enveloping her entire face with it. Ah. Looking back, it was not the first time, but this one that may have been the first button leading down an irreversible path.
