Punishment
"Minhi..."
"Yeah, Oppa?"
"I finished eating..."
Whether it was because of everything he'd been through in such a short span of time, he'd thought he wouldn't be hungry—but once he started eating, the hunger must have been there after all, because he cleaned his plate in no time.
After finishing every last bit of the rice and the few side dishes she'd brought, Minhi carried the empty bowls out on the tray, then came back in.
"Oppa."
"Yeah, Minhi..."
"Time to go wash up, right? You sweated a lot earlier, and you should clean up before bed, don't you think?"
"Y-yeah... that makes sense..."
"Then just wait a second. I'll untie you."
The handcuffs that had bound his wrists had already been unlocked; now Minhi began undoing the ones still locked around his ankles.
With the tiny key she opened the lock, and at last the restraints holding his body—
Ah...
The chastity belt was still there.
As long as he didn't get hard, it didn't really hurt—just a dull heaviness down below, nothing more.
"Alright, let's go wash up, Oppa. I'll scrub you clean everywhere~"
"Ah... okay."
Minhi took his hand and led him straight into the bathroom.
The bathroom was nothing special—just an ordinary home bath, with two plastic stools off to one side.
"Sniff... sniff sniff..."
Minhi suddenly buried her face against his shoulder, inhaling deeply as she began pushing him back against the wall.
"M-Minhi..."
"Sniff sniff... sniff... Oppa... do you know how filthy and lewd you smell right now?"
"Th-that's..."
After the drugs earlier, every fluid his body could produce had poured out of him, and he'd been left lying in it for hours—of course he reeked.
"Anyway... the lower I go... sniff sniff... the thicker the smell gets..."
Pinning him to the wall, Minhi dropped to her knees on the bathroom floor and pressed her face right up against his cock, breathing him in.
"Haaa... Oppa, how badly do you need to cum? Look at all this precum still smeared all over the chastity belt..."
"Th-that... I couldn't help it..."
"Heheheheuuu... God, seriously... your smell is so addictive I want to bottle it into a perfume..."
In the end Minhi grabbed the chastity belt and flicked her tongue through the piss-slit opening, lapping at him.
"W-wait! M-Minhi!"
He tried to push her head away, but his strength wasn't enough to move her.
"Stay still, Oppa..."
Then she lifted her head just a little and looked up at him with a dead-serious face.
"We're having a nice time right now. Why do you keep interrupting? You want me to just leave you tied to the bed?"
"Ah... no..."
"I keep going easy on you, keep calling you cute, and you just keep pushing it, Oppa?"
"M-Mi... I'm sorry..."
Looking up at him, Minhi showed no intention of stopping—her hand fondled his balls while she stared at him with cold eyes.
"Just stay still... Don't do anything I haven't allowed. Keep this up and I'll bring the cuffs back so you can't move at all......... You're seriously pissing me off..."
After that icy glare, Minhi turned her attention back to his cock locked in the chastity belt and resumed flicking her tongue through the piss-slit.
"Hh... hnnngh..."
Th-this isn't right...
Family... family... she's family... f-family...
His little sister's tongue licking through the chastity belt's opening kept trying to make him hard, but the cage blocked every attempt at an erection—and as the tip of his glans brushed faintly against her tongue, soft moans slipped out. He had no choice but to clap both hands over his mouth to smother the sounds.
"Hnnngh... hnnn... hh..."
"Ah... so fucking teasing..."
The one touching him—no, touching the chastity belt—Minhi stood up abruptly and walked out of the bathroom.
"Haaa... haaa..."
With Minhi gone, he thought he might finally catch his breath.
But she was back almost immediately, carrying a key and a small pouch.
"I was really planning to leave it on until my period was over... but it's your fault for smelling this filthy and lewd, Oppa..."
Minhi unlocked the padlock holding the chastity belt shut.
Click.
The key turned, the lock fell open, and the chastity belt that had been sealed tight finally came free—after hours, his cock was liberated.
"Haauup~"
"Hhkkuuugh!!!"
The instant the belt came off, Minhi took his half-hard cock into her mouth in one go.
Slurp, shluuurp.
"Wai— hhkkuuut... st... stop..."
Was it because he hadn't cum in so long?
Contrary to what he'd expected, his cock tried to shoot and harden all at once; he clenched his ass as hard as he could and held it back.
"P-please... nooo..."
How could he... with his little sister...
How could he have sex with her... absolutely not...
He held on with everything he had.
He held and held, but...
The cock Minhi was sucking was still an animal at heart—no matter how hard he clenched, it slowly filled with blood and began to stiffen.
Shluurp, slurp.
"Hhkkuuugh... st-stop..."
A cock that hadn't been allowed to cum filled with the urge to ejaculate almost immediately.
He had no choice—he grabbed Minhi's head as she sucked him and shoved her away with all the strength he could muster.
Thud!
She toppled backward; her head hit the bathroom floor with a solid thud. Clutching her head in pain, she glared up at him like she wanted him dead.
"Ah, fuck, seriously..."
Minhi slowly got to her feet, still holding the spot where she'd hit her head, and came toward him.
"Oppa? What the hell do you think you're doing?"
"Mi... Minhi..."
Whether it was because he'd shoved her head, Minhi was furious—she closed the distance until she was right in his face, looking slightly down at him.
"I'm trying to fucking make your cock feel good and you shove me? You don't want it this time either?"
"Th-th... even so, this isn't okay..."
"What isn't okay, you fucking brat? You're in heat right now—look how hard you are. Aren't you?"
The cock that had already been in Minhi's mouth stood rigid and glistening with her spit.
Then Minhi slammed him hard against the wall, her hand roughly descending to seize his cock.
"No, this is the perfect timing. Right? Oppa? Answer me."
"Th-this... isn't okay, Minhi..."
"What isn't okay? Not okay again? Then when is it okay—you want to tell me that, Oppa?"
"Th... that..."
The sight of Minhi raging at him made his throat tighten; his vision started to blur with wetness.
"Why? I'm not even scolding you right now—we're just talking. Why are you about to cry again?"
"Th... th-th... this..."
"Stop shaking and say it properly. You're starting to piss me off."
He was on the verge of crying like a child, so he took a moment to steady his breathing.
I can do this...
I can say it...
I can just tell her this isn't okay...
It's not hard, right?
After calming himself a little, he looked at Minhi, ready to speak.
She was staring at him with eyes that looked ready to kill, and the hand still wrapped around his cock was slowly tightening.
"Can you talk now?"
"Y-ye... yeah..."
He'd steadied himself with a deep breath and was supposed to say no...
But faced with Minhi's cold eyes and the grip tightening around him, every word he'd prepared and every resolve he'd steeled turned into a blank page in an instant.
"Hah... seriously, how many times have I gone easy on you today already?"
"I... I'm sorry..."
That wasn't what he'd meant to say—it just came out on its own.
"Sorry for what?"
"For... shoving you..."
"Yeah. No matter how you look at it, that was your fault, Oppa. You almost killed me for a second there. Of course you should be sorry..."
Still staring at him coldly, Minhi's hand left his cock and slowly climbed his body until her fingers gently cupped his cheek.
"Are you really sorry?"
"Nngh... y-yeah... I'm sorry, Minhi..."
"You did something wrong, right?"
"Yeah..."
"Like I said earlier—when you do something wrong, what do you have to take?"
"P... punishment..."
Tap. Tap.
Minhi lightly patted his cheek, then brought her face close and gave him a soft kiss on the lips.
Her peach-scented lips brushed his, pulled back, then kissed him lightly again.
Chup. Chup.
"Huuu... this is just a kiss I wanted before your punishment starts."
"Yeah..."
"From now on, no more casual speech. Answer me formally for everything, understand?"
"Yes..."
Having ordered him to use formal speech, Minhi took the pouch she'd brought earlier and dumped its contents in front of him.
A soft pink mass with a bit of sticky liquid inside tumbled across the bathroom floor.
"I wasn't originally planning this, but Oppa trying to kill me earlier changed my mind..."
Minhi picked up the soft pink object from the floor and held it up for him to see.
It... it looked almost like... a hole shaped like a woman's sex. She showed it to him, then slowly began sliding it onto his cock.
"Hh... hnnn..."
The thing was a little cold, and it slowly swallowed him all the way down to the base.
"Do you know what this is, Oppa?"
"I... I don't know..."
"It's an onahole. An onahole. Guys use these to jerk off—but looking at you, you don't even know what this is. You're really clueless about this stuff, huh?"
"Y-yes..."
Minhi fitted that onahole onto his cock and began slowly stroking it up and down.
"Hh... hhkkuu... Mi-Minhi..."
"Casual speech. And hands behind your back."
Just a few strokes and the urge to cum surged up; his hands rose toward his body on their own.
"Mi... Minhi... hnn... st-stop..."
"Haaa... seriously."
Minhi stopped moving the onahole.
"Oppa. Hands behind your back."
"Y-ye... ha... hands behind my back..."
He did as she said—clasped both hands behind his back. She pulled him from the wall into the center of the bathroom, then from behind took hold of both his thumbs.
Then Minhi whispered into his ear from behind.
"The punishment I'm giving you from now on is really simple. You just have to say something, okay?"
"Y-ye... yeah..."
"If I stroke this onahole like this, Oppa will cum eventually, right?"
"Yes..."
"Then all Oppa has to do is look at that mirror and say one line. Simple punishment, right? Easy?"
The bathroom mirror reflected them both.
Minhi behind him, holding his hands, one of her hands gripping the onahole—and him...
"Every time Oppa cums, if you shout 'I love you, Minhi,' you win. Simple, right?"
"W... what if... I d-don't say it..."
"Then we start over from the beginning until I'm satisfied. So, Oppa~"
Minhi began slowly stroking the onahole she held.
"Don't skip any. Make sure you say it properly every time ♡"
