Chapter 9: Off to School, Master Cock
The hot, stimulating sensation pulsing from his lower abdomen roused Oppa from sleep. He cracked his eyes open blearily. Something was wriggling under the blanket—no need to even check what it was. Without lifting the covers, Oppa kept up the pretense of being asleep, propping his head on his arm as he savored the feeling on his morning-hard cock.
The scorching heat of her palate and tongue, the waves of pleasure—it nearly drew a moan from him before he could stop it. Holding it back was pure torture, if torture could feel this good. Where had that old, clumsy mouth-pussy gone, the one that used to nick his skin with teeth even when she was being careful? His little sister's blowjob skills had pinpointed his sensitive spots with expert precision, making him proud as her big bro.
She puffed her cheeks with air, teasing his glans with feather-light breaths. Or she'd suck the air in reverse, vacuum-sealing her cheeks. Tricks she never could've pulled off before. But what impressed him most was her caution. Morning wood needed gentle handling—too much intensity first thing could turn a refreshing start into a slog. She dialed it just right: enough pleasure to thrill, but soothing too. Her technique earned top marks.
And top marks deserved a reward.
"Almost there. This time, you can just swallow without showing it off."
"Mmph??"
She probably wanted to ask when he'd woken up. But with his cock plugging her mouth-pussy, words were impossible. Oppa didn't warn her—just fired straight into her throat the second he finished speaking. The flood hit her palate like a torrent; Hyeonju gripped the bedsheet, sucking desperately to not spill a single drop.
True to form, her devoted service paid off. She slurped every bit down without a leak, gulping it steadily as it came, then polished off the remnants clinging to his shaft. She even vacuumed up her own saliva before finally pulling away.
"Hey! If you're awake, say something! You scared me!"
"Sorry, sorry. You looked so into sucking my cock, I thought about letting you keep going. Didn't wanna interrupt your fun."
"As if! Who's having fun? Morning wood duty's just basic for a bed-warmer. Don't act like it's some treat. What, you think your dick's all that?"
Even as she scolded him, Hyeonju's pussy was weeping for cock, clit standing at full attention. Oppa couldn't see from his angle, but her fingers had been working overtime on it moments ago—a top-secret matter. He always pounced on any weakness to tease her, so no way was she showing it.
Whether he sensed her thoughts or not, Oppa shrugged and slid out of bed.
"Man, nothing beats a wake-up blow from my little sis. Body feels light as air. Mom's are so intense, they leave me drained—like she'd wring my back dry. Yours hit perfect, no afterglow lag."
"Wh-what? Hmph... Yeah? Well, guess I nailed it, even if I didn't mean to. Unlike you, I'm top-tier as a meat toilet. This is easy stuff. Speaking of—comparing me straight to that hag-mom? Kinda hurts my pride, y'know? Ahem."
Hyeonju tilted her chin haughtily, playing it cool like the praise meant nothing. But her twitching cheeks and lips screamed how thrilled she was. Dragging Mom into it just to one-up her? Oppa smirked inwardly—his sis was shaping up nicely.
"Anyway, shouldn't you be getting ready? School's right next door, but you're cutting it close."
"Shit! What time is it...? Whoa, for real! I'm gonna be late! Even with school this close, teachers'll chew me out... This is all your fault!"
She turned the blame on him out of nowhere. Oppa shrugged innocently.
"What'd I do? I didn't even move."
"You slept in, so the blowjob ran late! Useless in life!"
He could've shot back that she should've started earlier if she wanted him up sooner. But surprisingly, Oppa had a shred of conscience. No point arguing when she wasn't wrong.
"Ugh, can't live with you!"
Hyeonju slammed the door and bolted to her room. Any slower and she'd actually be late. Oppa scratched his ass, following at a leisurely pace. Wonder what's for breakfast?

"Alright, sweetie. Mom's off to work~ Hate leaving your side even for a sec, but duty calls... Wait for me, 'kay? ♥ Mwahhh~"
Yu-ran cooed at him less like a mom, more like a girlfriend in heat. Her goodbye went beyond words—a deep, devouring kiss and tight hug that had Hyeonju cringing in secondhand awkwardness. Since when's this hag so clingy with him?
"...Mom, I'm right here."
"Oh, right. Have a good day. You too—off to school."
Her response to Hyeonju was curt as ever, polar opposite to Oppa's treatment. She wanted to complain about the favoritism, but it'd just drag things out. Better keep quiet. Even after opening the door to leave, Yu-ran kept glancing back at Oppa. How's she gonna function at work like that? He's not a kid.
No matter how much it irked her, Mom was gone—Hyeonju's cue to head out too.
"Hey, you hitting school today or what? Teachers and kids might hassle you, so gimme a heads-up."
"Dunno... Probably after lunch. Till then, messing with the neighbor wife onahole."
"Living the dream, huh? Whatever, doesn't bug me. Anyway, do your thing."
"Huh?"
Hyeonju bared her teeth, glaring.
"What else? You know the drill—when I head out, you greet my cock proper. 'Off to school, sir.' Forgot already?"
"Oh yeah. My bad."
Oppa grinned like he'd done it on purpose, cock springing up. If it weren't prime dick, she'd smack him. To avoid tardiness, Hyeonju dropped to her knees quick, lowering till her lips brushed the plump glans. She planted a wet smack right on it.
"Off to school, Master Cock."
"Yeah, have fun."
"Not to you. To Master Cock."
"Same diff."
"Not to me."
Classic sibling sniping. Hyeonju stood, done. No time left—school was close, but gates waited for no one. Nothing more to say to Oppa. She shoved on her shoes and sprinted out, vowing to curse him if she ended up late.
Home to school was a ten-minute walk tops. No excuse for lateness, right? Wrong—proximity bred complacency, and Hyeonju often cut it razor-thin. Far students were late; close ones too. Headache for the school. Luck held today—she dashed like hell and slipped through just in time.
Principal Jeong Hana eyed her disapprovingly—close-home girl, always borderline—but results mattered.
"Cutting close again? House next door, and you're still this iffy every time?"
Finally in class, catching her breath, friend Seong-mi ribbed her. Hyeonju waved it off dismissively.
"Bro kept me up till death serving his cock all night. Everything else average, but that stamina... Held out till 2 a.m. Exhausted much?"
"Yeah... Your bro's stamina is insane. Wore out me and my mom tag-teaming. Daily? Brutal."
"Right? I'm dying here, and he hasn't a clue. Makes my blood boil—gonna get revenge someday..."
Seong-mi gave a wry smile at Hyeonju's open Oppa-hate. Yet she always sides with him at crunch time. Just sisterly love, maybe.
"...Anyway, homework done?"
".............What homework?"
Hyeonju's lip quivered. Homework? Never heard of it.
Denial didn't erase reality.
"Book report. Due today—forgot?"
".....................Oh."
Her upper body crashed onto the desk like a felled tree. A world-weary groan escaped, deflating like spent air.
"I'm screwed."
