RE: Keep it in the Family (Secret Class) 165 — It Looks Delicious—Would it Taste Delicious Too? II (NSFW) (Conclusion)

Su Ah's POV:

She halted and breathed out, gradually letting go of the breath she hadn't realized she was holding back. 

Her thoughts raced wildly. She'd encountered descriptions like this endless times in stories, yet reality hit differently. No amount of imagination could have readied her for the thick shaft hovering so close to her face.

His gaze burned with intense heat, scorching her skin. His fingers wrapped around her head. They neither tugged nor pushed, just held firm, clenching tighter. She knew it wouldn't be long before he took charge more aggressively.

What on earth should she do next?! Kiss it? Or... maybe lick it...? Or—?

Mentally, she wasn't ready at all.

A spark of bravery, mixed with the thrill of the forbidden, propelled her onward. She'd trust her gut.

Her pink tongue emerged shyly, circling the tip. The texture surprised her with its softness. She licked off the drop of pre-cum glistening at the opening.

From above came a sharp hiss of breath as reward. Jae-il’s hips bucked, pressing more of his hardness to her lips. Su Ah closed her eyes, relishing the flavor—the subtle salt, that musky masculine essence she'd never quite pinned down.

Su Ah wrapped her tongue around it, tentatively tracing the ridge, then drew back, her jaw slackening in shock at the electric jolt that shot straight to her center. She swallowed hard, her body heating up even more.

Emboldened, she repeated the motion. The glide of her tongue and the tremor racing through her as his skin pulsed in her mouth amazed her. A rush of wetness flooded her core; she gripped his strong thighs for support, knees weakening.

The rush of dominance caught her off guard and thrilled her.

She withdrew again to glance up. The taut cords of his neck, the fire in his eyes ignited her excitement. She felt intoxicated by this newfound control she held over her younger brother.

Who could imagine so little effort would have him so completely under her spell? 

Moistening her lower lip, she licked broader now, the flavor intensifying with his growing need. A choked rumble echoed from his chest, vibrating into her hands. She gasped deeply between each wide lick, flushed with exertion and arousal.

It was... mind-blowing, addictive—this taste bursting repeatedly on her tongue. A tangible essence coating her swirling muscle, clouding her mind, igniting her body. His fingers tangled deeper in her messy hair, knuckles whitening as she experimented more.

A drawn-out moan tore from his chest. The way it made his length throb wildly beneath her tongue spurred her confidence.

Swirling around the head, she ventured down the shaft. Without warning, he thrust forward, sliding past her lips into her warmth. His groan deepened to a raw rasp, the sound sending shivers down her spine, pooling deep inside.

His thighs and hips quivered faintly. "Oh god. Su Ah, your fucking mouth." He groaned, lost in sensation as his fingers clenched her hair into fists. Su Ah glanced up, sucking softly. His jaw hung loose, sharp teeth visible behind open lips as he exhaled sharply. "Fuck, keep going..."

Su Ah worked him with tighter lips and curling tongue. She took him a bit deeper each time, testing her limits, seeing how far the tip could reach.

The fist in her hair relaxed into a guiding pressure, urging her down further, the girth stretching her jaws wide at the back of her tongue.

Not fully inside yet, relaxing around the intrusion proved tough; her mouth buzzed with nerves, unease, and delight. Then a moan escaped her, vibrating up into Jae-il, letting his cock slide deeper as his hips moved.

A soft 'gukh' escaped her, saliva overflowing in streams along her tongue and his heated shaft. Her eyes flew wide. Gasping as her gag reflex hit suddenly, panic surged—she choked, coughed, tears welling, airway obstructed. She yanked back in alarm, gasping for air while staring up.

"Are you okay, Noona?" Jae-il steadied his voice somehow, looking down with clear worry... and lust. Even this choking moment oddly aroused him in a bizarre, humiliating way.

His erection remained rigid between them, glistening with her saliva, a shiny strand still linking it to her parted lips.

"I-I'm fine... sorry..."

He exhaled. "Don't overdo it, Noona. If you want, we can—"

"No. It's fine."

Imagining how far her Unnie had gone for him, she'd match that dedication to avoid being outdone.

Su Ah panted heavily now. Her teary eyes fixed on the thick, curved shaft; she grasped it, the flesh swelling between her encircling fingers. Slick pumps followed, her drool easing the glide, spreading over the enticing skin.

Jae-il’s low purr escalated to a prolonged growl, then a hiss and curses as Su Ah confidently engulfed him again.

And he growled, teeth clenched to muffle the sound within their private space. 

Su Ah nearly wavered. No word captured how masculine and hot that noise sounded; knowing it was hers alone, that no other woman heard these pleasure-filled sounds she provoked—it twisted heat in her clit, building fast.

Su Ah instinctively pressed her tongue along the veined underside. His hips shifted, thrusting once more, a touch deeper.

Her fingers dug into his thigh muscles.

"" The gag reflex struck again as Jae-il's cock pressed deep against Su Ah's tongue. Before she knew it, it lodged firmly in her throat's tight grip. Su Ah's eyes rolled back, her neck went limp, confusion hitting until her nose buried in his groin and Jae-il cursed once more. ""

Her head started a gentle, experimental bob on its own. Her throat constricted fiercely. Air felt scarce. Would she vomit or faint? She no longer cared or knew.

Though her brother nearly choked her, Jae-il's earlier purrs vanished, replaced by raw, escalating groans filling her ears as he neared blissful heights.

Damn. Countless wrongs and taboos surrounded this, yet Su Ah had never felt anything like this rush while struggling for breath.

"God, it's so fucking amazing." Jae-il sounded stunned; when Su Ah looked up to meet his eyes, they shone with awe and wonder, mouth open.

Su Ah retreated briefly for desperate air, but her throat rebelled at the absence, producing more guttural, obscene noises to her frustration.

Tears stinging bleary eyes, she quelled panic, concentrating on the feel, yielding to him. In. Out. Slowly. Harder. 

Obscene, sloppy sounds emanated from her mouth, drenched in saliva.

Instinct took over for Jae-il; his body tensed as the sensitive head glided down her throat, restraint shattering.

Su Ah forgot breathing existed. 

Her mind jumbled—pain, strain, fullness, and choking eclipsed by her drive to please him. He craved this, so she allowed quicker rocks into her.

Her inner thighs dripped, arousal pooling and trickling down. Each motion clenched her empty walls in need; unaware, she parted her legs, grinding her hips on the bed, whimpering at the void.

A shaky breath escaped him. He tenderly swept hair from her eyes, then yanked roughly, stuffing her full as his cock throbbed larger.

One hard thrust. Two, then three. A shiver raced up her back, her core spasming at the tug. Suddenly, orgasm hit, soaking her as her tongue slackened. She sagged, her reaction apparently intensifying his final labored pumps into her tight mouth.

Perfectly timed, Jae-il unleashed a final ragged snarl. "Fuck, Noona—!" His abs carved into sharp ridges, legs shaking wildly—she knew release was here.

Hips stuttering, he groaned breathlessly. Control broke; his body convulsed, flooding her mouth with forceful jets against her tongue.

Su Ah's eyes rolled back. Delicious, was all she could think. 

Assaulted in the most exquisite, sinful way, cum poured over her tongue—salty, musky, irresistibly addictive.

‘’

Hard to process that this moment had arrived. All the fantasies fueling her stories... unfolding now. 

"Krnf..." Su Ah gagged, throat raw and aching, lungs fighting past the swollen tip, but his grip held as he emptied inside.

Suddenly, thick ropes of cum blasted her throat's walls, making her pull back for air before another load hit her tongue. 

A third painted her stunned face. A fourth arced high, landing on her slick, sweaty thighs. 

Aftershocks lingered briefly before Jae-il withdrew, slumping against her desk. His semi-erect cock dripped onto the floor.

Su Ah collapsed onto the bed, pulsing heat between her legs. Her brother's flavor lingered; though tempted to spit, she couldn't.

This taste hooked her.

Staring dazedly at the ceiling.

Slowly, she swallowed.
