Su Ah's POV:

  The ceiling swam. The glow-in-the-dark stars she’d stuck there years ago blurred into streaks of neon green comet tails. It was all so dizzy.

  Su Ah y there, chest heaving, the aftershocks of the orgasm radiating outwards in diminishing ripples.

  Her brain was static. White noise. No signal.

  She felt Jae-il’s fingers slide out. The wet, slick sound was so fucking loud. It was the lewdest thing she had ever heard. Her pussy fluttered at the withdrawal. She was no doubt leaving a huge stain on her sheets right now.

  She realized her ears were ringing.

  Then his lips and teeth and tongue were dragging wetly over the crease where her thigh met her hip.

  Su Ah couldn't speak. She just let out a fractured breath, her head lolling to the side. She saw her jeans on the floor. Her panties a small, ruined heap of ce next to them.

  "Mmmm~"

  He sounded content as he pped the slick off her outer bia.

  That sound would no doubt py inside her masturbation fantasy memories bank for ages.

  "Noona, you're so tasty."

  She wondered dazedly if that was something one should actually be saying to one's sister, then decided that she didn't care; not when those same lips were kissing the tip of her still pulsing clit.

  "C'mon, say something. Aren't you going to take notes now about your experience here~?"

  "Haah, aaah~"

  Okay, she could definitely do without his ego showing its ugly face after making her lose the ability to function.

  Su Ah blinked rapidly, as if coming back to life. A shiver crawled through her, the st remnants of her release gradually petering out, the pangs ebbing off.

  She felt numb and jittery.

  She expected him to stop. She expected him to crawl up, wipe his hands, maybe kiss her forehead and tell her that was enough tuition for one day.

  Jae-il didn’t move up.

  He moved down.

  Fuck, was he seriously still not done?

  His hands, still wet with her, gripped her hips. His thumbs dug into the soft flesh there, bruising in a way she knew she would admire in the mirror ter.

  "I don't think you were paying enough attention." Jae-il murmured, purples eyes peeking mischievously from between her legs. "You got distracted halfway. Seems you didn't learn your lesson yet."

  The hell…?

  Was he really serious about teaching her here…?!

  Before she could protest, before she could even gather enough oxygen to say his name, he buried his face back into her.

  Then the ft pne of his tongue was there, gliding back along her slit.

  "Ah—!"

  For a moment, Su Ah just stared at her hands, folded across her breasts, seeing that they were shaking as if she were freezing to death, before her eyelids drifted down and her palms covered her eyes in disbelief.

  He didn't use his fingers this time. He just used his mouth. His tongue was broad and ft, dragging from the very bottom of her opening all the way up to the swollen, sensitive nub of her clit. He licked her like she was something sweet that had spilled, something delicious to be cleaned right off the fucking ground.

  That broad tongue nudged against the tender bud, then pped firmly.

  Her muscles shuddered in his grip.

  She made another noise, and another, all her inhibitions gone in the face of this molten, decadent feeling.

  It was all too sensitive. It was agonizing.

  "Jae-il, wait—" Her hands fluttered, trying to find a purchase. They nded on his head, fingers weaving through his dark hair. She meant to push him away. She really did. The sensation was bordering on pain, the nerves too raw from the first climax.

  But the moment her fingers touched his scalp, she pulled him closer instead.

  He moaned into her, the sound vibrating straight through her clit.

  He knew. The bastard knew she couldn’t take it, and he loved it.

  He switched tactics. No longer broad strokes. He swirled the tip of his tongue around the hood, teasing it, flicking it lightly, then backing off.

  Su Ah’s hips bucked off the mattress.

  "Please—" She whimpered. "It's too much."

  "Is it?" He lifted his head just an inch. His chin was wet. His lips were red, slick with her fluids. He looked wrecked. He looked beautiful. "Because you taste like you want more."

  He didn't wait for an answer. He dove back in, and this time, he used suction.

  Su Ah’s back bowed so hard her shoulder bdes dug into the mattress. A high, keening noise tore from her throat. It wasn't a word. It was just sound.

  "Noona, you have to keep quiet if you don’t want to risk getting caught, you know? Do you want Mom or Mia Noona to know what we're doing here behind the locked doors~?" Jae-il mocked cheekily.

  Despite his taunting, he slowed, dragging his tongue torturously slow against the engorged bud. Su Ah clenched her hands helplessly around her mouth.

  He sucked hard, cheeks hollowing, drawing the little pearl into his mouth, while his tongue shed against it. She couldn’t think, could hardly breathe, and Su Ah jerked so hard his arm cmped down and pinned her there.

  This couldn’t possibly be real, this sort of pleasure should be illegal—

  The hands around her mouth couldn’t hide the animal noise that was building in her throat, guttural and broken, like her body no longer remembered what her voice should sound like, so that when Jae-il continued and he sucked harder and faster, the sounds were beyond comprehension.

  She looked down at him. The sight of her brother, the golden boy of Korean football, face buried between her thighs, devouring her like a man possessed was—

  His eyes gnced up, half lidded and shining. His cheeks were a mess, her sticky fluids all over his face, but Su Ah had never seen him look so devastatingly perfect, even through the tears blurring her vision.

  She cried out a sob, the sheer intensity was almost painful.

  "I-I'm gonna come, J-Jae-il..."

  Su Ah smmed her head back into the pillow as her spine snapped taut.

  There was no warning, no teasing, bubbling pressure. It was just a sudden explosion of hot white ecstasy, as if a truck loaded with pure pleasure had rammed straight into her at full speed.

  Su Ah's throat locked. Every muscle tightened into exquisite tension, and for a split second, she thought she'd lost consciousness altogether.

  When she drifted back down to earth, it was to the feeling of Jae-il pressing soft, gentle kisses against the inside of her trembling thighs.

  He trailed his lips all the way up to the bones of her hip before he nuzzled her stomach.

  A chuckle.

  "Noona, you completely messed up my face..."

  The bed shifted.

  She managed to look down between the valley of her breasts, finding him bracing himself against the bed, with one arm on either side of her. A thin coat of translucent white fluid was smeared on the lower part of Jae-il's face, glistening under the rays of the sun.

  "But don't worry. I enjoyed every second."

  Su Ah breathed. The flush spread to her neck as her face colored at the sight of her own cum all over her brother's face.

  "L-Like it... huh?"

  Her eyes swirled in a daze.

  "Yep. Yum, yum~"

  He really said that.

  His stupid smile only grew wider upon her speechless expression. Su Ah watched her little brother zily climb further onto the bed and hover over her, using his arms to propel himself up.

  The mattress dipped under his knees and elbows. He straightened himself, his eyes slowly sweeping over his sister's nude, flushed form, still heaving from the aftermath. And then he pulled his shirt up over his head in a swift motion and discarded the garment on the ground.

  Now shirtless, his magnificent physique stood in full glory under Su Ah's mushy mind.

  The girl wanted to sp herself, wondering where her pride and strong will had gone. Where had the former 'indifferent and aloof' Su Ah gone to?

  When did those proud walls she'd so carefully built colpse?

  His physique, still clearly honed by constant football practice and training, was a true, splendid testament to that of an athlete. All sharp cuts and defined muscle groups. Her brother had always been blessed. Broad-chested. Defined waist. His entire upper body, including his arms, were as lean and sinewy as a runner. No, perhaps a little bigger. Impossibly perfect.

  Droplets of sweat slipped between his firm pecs, traveling down to the defined lines and dips of his abdominal muscles. Su Ah let her eyes dip even lower, following that tiny, shimmering pearl of sweat, only to find an obscenely huge bulge on his pants.

  At some point, it was undeniable to Su Ah that she'd fallen and lost her cool. She was drooling, her body temperature still ramping up. Even while already drained by a double-orgasm, the sight of him, as perfect and majestic and male as he was, was giving her goosebumps.

  "You've never seen one in real life, have you?"

  "H-Huh...?"

  Jae-il didn't hesitate; in one smooth pull he removed his pants and underwear and his erection jutted out. The massive appendage swung as it was released from its confinements.

  Its towering shadow split her face in two.

  Su Ah let out a loud gasp, staring at him and his length in a stupor.

  "Oh God."

  Oh, good gravy—it was enormous, with a fat mushroom shaped pink head and a wide, veiny shaft that curved upwards like an angry fist.

  How the hell was that thing supposed to fit inside any female orifice, not to mention hers—?

  Her hands itched. She wanted to touch it.

  She had absolutely no fucking idea why.

  This time the deep shade of red extended all the way up to the tips of her ears and nose.

  "Do you still want to continue, Noona?"

  Su Ah’s eyes widened.
