Still Like That Until the End?
—Squelch, squelch—
A lewd, wet racket filled the bathroom.
"Hh… hnnngh…."
"Oppa, are you holding back your moans? Why? It's just the two of us right now."
"Hnn… hnnngh… ah, no…."
"Fine, holding them in is your choice—but that doesn't change the fact that you still have to tell me you love me when you come."
Behind him, Minhi kept working the onahole wrapped around his cock without the slightest hesitation, pumping it hard and fast.
It wasn't that he never masturbated—but this was nothing like doing it with his own hand. It felt too good. Way too good.
I shouldn't be feeling this….
"Hhk—nnngh… haaah…."
"For someone who's supposedly holding back, those moans keep spilling right out of your mouth, Oppa."
"Th… haah… that's not true…."
Unlike a hand, the ridges inside the onahole kept raking over his cock without mercy, and the urge to come was climbing from the base, higher and higher.
Ah, no….
I have to hold it….
Minhi's watching from behind me… I can't come… I can't….
As a man—as family—he shouldn't have been doing this at all. But that had nothing to do with the way his cock was surrendering to the pleasure of the onahole Minhi was shaking around him, the climax surging up whether he wanted it or not.
"Come on—spurt it out for me, Oppa~"
"Hhk—nnngh… haah… haaah…."
He clenched down with every scrap of will he had left, fighting the orgasm with nothing but raw refusal. But Minhi, waiting for him to break, only shook the onahole harder.
—Squelch! Squelch! Squelch!
The filthy wet sounds rang out—and he broke.
Pleasure won.
—Spurt, spurt—
Some animal instinct buried in the body took over. He started emptying himself into the onahole, his hips pushing forward of their own accord.
"Hahahaha—Oppa? Are you trying to knock up the onahole right now?"
Minhi watched it all from behind him, laughing as she looked at him.
"Hh… hnnngh… hh… M-Minhi…."
"Mm, Oppa?"
"I… I l-love you…."
"Heeheehee~"
He had only wanted this "punishment" to end as fast as possible. And so, after he came, he said it—he told Minhi he loved her.
"Aah~ What better punishment could there be in the whole world, Oppa?"
Still holding both of his hands from behind, Minhi rested her chin on his shoulder and peered at his face from the side.
"I get to work off your sex drive for you like this, and I get to hear you say you love me. Win-win, right?"
"Hnnngh… th-that's it, then… we're done…."
"What are you talking about, Oppa? This is just the beginning."
Minhi pressed herself flush against his back and started pumping the onahole again, rough and relentless.
—Squelch, squelch—
The bathroom, quiet for only a moment, filled once more with those wet, obscene sounds.
"Ha… haahghh… s-stop… hnn—"
His cock was still raw and hypersensitive from coming only seconds ago, and Minhi was shaking the onahole around it without mercy. She worked it so hard he could see the semen he'd just shot inside frothing into foam.
"Stop what, Oppa? I told you—this is just the start."
"Hnn— I j-just came… p-please stop…."
"You're being punished right now. You think one round and we're done? What kind of punishment is that?"
"Please… M-Minhi… st-stop… hnn—"
She kept working his oversensitive cock, and his hips started shaking so hard he thought he might lose his mind.
"Aah~ Oppa? Are you shaking your hips like that because it feels good? That's it, right? Heeheehee—I'll make it feel even better for you~"
"I d-don't want it… stop…."
He thrashed, trying to wrench free of the hands pinning his wrists—but the more he struggled, the faster Minhi pumped the onahole, and the harder her grip clamped down on both of his thumbs until he couldn't move at all.
"Hhaagh… st-sto-o-op…."
The stimulation never let up. He flailed wildly, shoving his hips back to escape the onahole bearing down on him—only for Minhi's hands to follow, chasing him, shaking it even harder.
"Heeheehee~ Aah~ aah~ I love this so much~ Honestly, watching Oppa completely helpless, just spurting into his little sister's hands—I love it so much♡"
"Hnnngh… stop… stooop…."
"The way you beg me to stop is adorable too, you know♡"
I want to get away….
Under the excuse of "punishment," she's milking me like this—I want out of her hands….
His bound wrists wouldn't give. The farther he pushed his hips back, the more aggressively the onahole came after him.
Was this what it meant to go mad from pleasure? His body kept responding whether he wanted it to or not. Strength drained out of him. His legs wouldn't hold him upright.
—Squelch, squelch—
Under the relentless grip of that onahole, he came again—he had no choice.
—Spurt, spuuurt—
"Heh… hhk—nnngh…."
"There, there—our Oppa's working so hard, pumping it all out♡"
At least she paused while he was coming. He clung to that small mercy.
—Spuuurt….
The last of his semen drained out. Minhi watched him steadily from the side.
"Hheh… eehhh… n-now please stop…."
"……"
The moment he asked her to stop, the brows of the girl staring at him twitched. Her face began to cool, degree by degree.
"Hnnngh… M-Minhi…?"
"………"
Still looking at him with that cold expression, Minhi started tightening her grip on the onahole.
—Squelch….
She squeezed hard. The semen trapped inside forced out between the walls in thin rivulets—and then the pain started.
"Ugh… nnngh… M-Minhi, th-that hurts…."
"………to the end…."
Whatever she whispered was too quiet to catch. The pressure kept climbing, crushing his cock inside the onahole until the pain was sharp and real.
"Ghh— M-Minhi… l-let go…."
"……Really, all the way to the end…."
He still couldn't tell what she was trying to say. He just wanted to apologize—anything to make it stop.
"M… Minhi…."
"Oppa… you're really, truly selfish."
"Ghh—!"
His legs were still trembling from the orgasm. Minhi drove her knee into the backs of his and forced him down onto the bathroom floor, onto his knees.
"Honestly… do you even know how selfish you are?"
Then she let go of the onahole and his hands, reached into the bathroom cabinet, and pulled out a towel.
"I told you clearly I was going to punish you. Punish!Punish!!!Punish!!!!! Do you not remember me saying that? Are you an idiot? Are you a goldfish?"
The curses came out raw as she started tearing the towel clean in half with pure force.
"Why is this so hard for you to understand? I told you—what did I say you had to do during your punishment?"
"Ah… aah…."
"Not 'ah'—you fucking—!!"
Holding the half-torn towel, Minhi clamped one hand around both of his cheeks and looked down at him.
"Say it. Fast. What did I tell you before the punishment started?"
"Th… that… f-formal speech…."
"Good. You remember that much. Fine—we'll call the formal speech secondary. And what else?"
"And… a-and…."
"Don't stall. Say it!"
What did I even do wrong? He couldn't think past how terrifying Minhi looked staring down at him.
Too terrifying.
The way she was handling him—so aggressive, so ready to hit him the second he said the wrong thing—filled him with a fear that made him scramble for the right answer with everything he had.
"Th… that… s-so… I love you, M-Minhi…."
"See? You know it. You did it fine the first time—so why did you suddenly screw it up on the second?"
"B-because… it f-felt too… good…."
A lie.
The first orgasm—he hated admitting it, but after the chastity belt had kept him soft for so long, finally getting hard and coming had felt good.
From the second one on, though, it had only felt like being milked dry. All he had wanted was to run.
"It felt good? Having your little sister work an onahole on you until you came—that felt good?"
The words stuck in his throat. He forced them out anyway.
"Y-yes… it f-felt good…."
"It felt good?"
"Yes……."
He said it with a flush of shame, thinking it would cool her anger.
It didn't. She was still staring at him like she wanted to burn a hole through him. She let go of his face and went back to tearing the towel.
"Good that it felt good… good that it felt good…."
The towel in her hands finally split clean in two. She crouched down in front of him.
"Oppa."
"Y… yeah…."
"Having fun all by yourself?"
"N… n-no…."
"I didn't ask you for anything hard. Right? Just say you love me when you come. Was that really so difficult? You managed it the first time—why can't you do it from the second on? I even gave you time so you wouldn't forget on purpose, and you just sat there pretending you had no idea?"
She started rolling the torn half of the towel into a tight wad.
"I really do like you, Oppa… no—I love you. I love you so much I could die, love you, love you—and you don't even care how I feel. You just sit there killing time with your head empty…."
The rolled towel was a dense little ball now. She brought it toward his mouth.
"I think I've been too soft. I went easy on you because you're the Oppa I love, and that was my mistake."
"M… Minhi, I—I was wrong… j-just let me off this once…."
His hands were free. He brought them forward and begged, rubbing his palms together.
"There is no second chance."
The towel wad drifted closer to his mouth. Reflex made him clamp his lips shut and drop his head in a show of remorse—
"I told you. There is no second chance…."
"Nngh… M-Minhi…"
"Don't you dare close your mouth. Refuse me again and I'll make sure you can't live without those injections for real."
His whole body went cold at that single line.
The… injections… I hate them….
Just one shot earlier had left every inch of him screaming with hypersensitivity. He never wanted to feel that again.
The towel wad came closer. He opened his mouth and took it.
"Mmmpph…."
It filled his mouth completely. He couldn't speak.
"I'll carve it into that body of yours so you never make a mistake like that during punishment again. Oppa."
She took the remaining half of the towel and covered his eyes.
