RE: Keep it in the Family (Secret Class)

Su Ah's POV:

"Do you still want to continue, Noona?"

With him completely naked before her, and her utterly defenseless and sprawled beneath his taller body, Su Ah suddenly realized the reality of the situation.

She couldn't believe the conversation she was having right now; couldn't believe she was seriously considering taking her younger brother's cock. Su Ah gulped, her palms sweaty against the sheets.

It was, of course, impossible to miss his straining erection, stiff and throbbing against his lower stomach. That was only one major hurdle that they needed to jump over, and it felt pretty monumental.

To be quite honest, he was so hard and swollen already, just from eating her out. It was all real, not some gibberish conjured from the pages of her trashy novels. Real enough that a single bead of fluid leaked from the flushed, angry tip and pearled slowly down the veined shaft.

Holy fucking hell.

Su Ah swallowed thickly.

It was—

It was...

That couldn't fit. Absolutely could not. Could not, not even remotely, not the least. It was like the universe trying to put a square peg in a round hole, an alien entity from another world trying to fit in an entire other alien creature.

Impossible. Impossible. Im-fucking-possible.

"Noona...?"

Jae-il's low purr made her freeze—made her lose her train of thoughts.

"I—I..."

What should she do? What was the right thing to say?

The part of her, a reader of borrowed knowledge, only a writer of this kind of content, howled its protest. Take it. This was victory. This was the ending she'd tried writing a hundred times, a victory she'd scripted for other women, fictional characters who had their own sweet endings, but never herself. She had never known this touch.

This, now, here with the door locked, was the proof. One nod, and that impossible thing, her brother—her flesh and blood—would fill the gap between her thighs.

Her breath shuddered in her throat. It wasn't right. No, of course it wasn't! And she wasn't talking about the act itself, because duh, she just had her brother eat her pussy like a gourmet meal, as inelegant and primitive and wrong as that was.

She hadn't cared that his tongue made her climax twice, that he was her own sibling.

So what would that change by adding a penis into the mix?

In short, this wasn't about the act itself. No, the wrongness was that their mother still rested a single room away. That her Unnie was downstairs, lounging around and likely waiting for them, counting every minute they spent. They weren't in a hotel room, they weren't in a car, a yacht or even a forest cabin, a secluded place meant to fool around. No.

And here she was, deciding to have sex with him at a time when all four of them should be having lunch together.

Fuck, she needed to calm down. Her heart was racing so fast.

"Wait." Su Ah told him, shaking her head. He merely tilted his head, seemingly pondering her statement, before smiling in that lazy, content manner of his. "I—I... no, I mean, it isn't right... to do it here."

The prospect of their mother overhearing their commotion was horrifying and ridiculous.

She wanted to, she couldn't lie to herself about that. God, if she did. Temptation itself was staring up right at her eyes in the form of her brother's perfectly sized cock. She wanted to yank her hair out in frustration at the fact that her rational side was suggesting they’d postpone it when it wasn’t so dangerous.

Daylight still poured in through the curtains.

But she would prefer to actually be able to meet her mom's eyes later without stuttering like a crazy person

Su Ah didn't know whether what flashed through her brother's eyes was disappointment or relief, or a mixture of both.

Still, that cock, his cock, his damn, deliciously huge cock, would not give up its presence.

To give up on it completely, after they'd already gone this far—it felt like such a waste. It pained her. It physically pained her. It took every ounce of restraint not to simply give in and see what it was that her novel's heroines were screaming themselves hoarse about.

And that was when an idea popped into her head. It was so clear!

"Let's go to the mountain... to watch the comet." She proposed, her words spilling out in a stammering rush. Of course, the mountains! "Y-You promised me, didn't you? Jae-il, that we'd watch the comet together!"

That they'd take this whole incestuous matter somewhere secluded, that'd take their privacy issues out of the equation. Somewhere, anywhere, didn't matter as long as it was somewhere no one would come knocking to barge into their lovemaking, as cheesy as the term may be.

Besides, wouldn't it be the perfect date too? The perfect atmosphere? In the mountains, under the stars, with the moon out, and the comet slowly streaking through the skies, the two of them would be watching the events of that night unfold while consummating the twisted bond between brother and sister—

"Yes, the comet..." Jae-il mumbled, backing away and off the bed. "Yes, I did promise you, Noona. When is this... phenomenon occuring?"

"It's already occurring!"

"Then..."

"But I'd like to take a better look at it. There is a place on the countryside. We c-could go there next week."

"Next week?" He nodded, thoughtfully, then smiled. "I'll keep myself free then."

"You have to." Su Ah propped herself back on her arms.

He grinned. "Right?"

Then, a moment of realization hit her. Jae-il was still naked as the day he was born, standing in the middle of her bedroom with his long, glorious manhood completely on display for her viewing pleasure.

"Umh... Jae-il, about that?"

"Huh? About what, Noona?"

The heat on Su Ah's cheeks grew almost unbearably scorching, yet her gaze wandered all the same, greedily drinking in the sight. "That..."

She lamely pointed at his crotch.

Jae-il could see where Su Ah's attention was wandering towards. He chuckled a bit before purposefully and exaggeratedly doing nothing. "Ah, yes, it's your first time seeing one up close, right? By all means, enjoy the view~"

A muscle in her cheek flexed involuntarily. "Sh-shut up."

With his usual pokerface, a fake innocence even, Jae-il merely stood in front of her.

And Su Ah swallowed as a different, terrifying curiosity took control over her. It seemed like, again, an obvious question that needed to be asked.

"H-how... what can I..." She swallowed. "I-Is there anything... I can do..."

'I mean, even though we're not going to do it now... shouldn't I try easing that... somehow?'

That erection just kept pulsing angrily.

Jae-il paused. When he spoke, his tone was careful. "That's..."

"Oh, don't worry, it's not a bother." Su Ah muttered quickly, trying to sound cool. "Well, you did make me feel good, so..." She went even redder, thinking she should be at least offering the same consideration. "Um, s-suck, or something?"

It was something she had read about as well, and had seen clips of; the thought of sticking something so damn big in her mouth was horrifying.

The possibilities and dangers involved. Choking. Injury. Sores.

But.

Now that it was in front of her. Jae-il. Her brother. The horrifying thought of putting it in her mouth didn't seem so... horrifying anymore. In fact, it kind of... enthralled her. She was curious of how it'd feel like, sliding over her tongue, hitting the back of her throat, and was curious of how he'd react. After all, it was supposed to be extremely pleasing for the receiving end.

The more aggressive the blowjob, the more her brother's face would distort in masculine ecstasy.

A soft hum left her lips. "Ah."

Jae-il's eyebrows raised in mild surprise. He probably wasn't expecting this kind of invitation, knowing how inexperienced she was.

"Noona..." He pursed his lips, his member jerking and twitching. "Are you sure?"

His face was dead serious and so were his words. He wouldn't even begin without being sure that the girl wouldn't chicken out the moment he would slip past those sweet lips, or that she was really comfortable doing something so invasive.

"Y-yes." She couldn't bring herself to stare directly at his eyes. The burning embarrassment in her gut wouldn't allow her. "B-but just a little... just to let you finish..."

Yes, it felt right. She’d help him out with that, and she’d find out what it was like giving… head.

She licked her suddenly dry lips as her brain provided a very detailed vision of his girth hitting the back of her throat. Would it hurt? Probably…

It couldn’t possibly feel good.

That said...

She leaned forward to get a closer look at his erection. At that prominent vein that ran the whole length of his mast. God, it was as intimidating as it was beautiful.

With trembling fingers she gingerly reached out, wrapped her fingers around the width, and it immediately pulsed at her touch. Her eyes lit up.

Damn... it was thick, and the texture was amazing. It was like silky, hot velvet covering a solid rock. Her hands instantly tightened, but only a second later loosened, fearing the consequence of strangling his dick.

But the notion seemed so stupid to her that it made her burst out a breath of stifled chuckle.

How could something this big be possibly strangled? If anything, this was like having a lethal weapon right in between her fingers. And it seemed a little hypocritical to have an oversized appendage be treated with delicate and tender care, especially since the owner of the same dick made a meal out of her with zero worries or fears, if that thing he did earlier was considered cunnilingus.

Despite that, Su Ah found herself asking the question to her brother. "What do you... want me to do?"

"Start slow. Don't try to force everything inside your mouth and instead just start with your hand..." Jae-il instructed, his breathing already growing shallower.

She exhaled, biting her bottom lip as she gave her brother's cock a careful squeeze, curling her fist around the intimidating shaft.

Her jaw fell.

It felt impossibly firm. Harder than her arm.

Salty wetness dotted her fingers, and a brief pulse of pre-cum slid over them.

A low, approving groan that sounded oddly gratifying came out from Jae-il's throat.

He thrust carefully into the tunnel Su Ah made with her grip. His movements were small at the start, barely enough to register as movement, but steadily grew more restless.

"Come, Noona, move faster."

He growled when her strokes came to a standstill. Su Ah had been so transfixed in watching the fat dick disappear and reappear through her enclosed fingers that it was almost hypnotic. Not that she could successfully wrap her digits fully, that is. His size was a clear testament that a woman's palm wasn't enough.

Not sure about what he was saying, and only half listening, Su Ah jerked faster at the sudden pressure.

The sounds Jae-il made were enough for her to make her want to register each one of them and listen to them on replay for the rest of her life.

"Haah, fuck." He leaned in, voice gravelly and so fucking sexy, with all his self-control completely crumbling. "Come, give me your tongue."

Her eyes widened.

Tongue—

There was a gleam in those languid purple orbs as he looked down at her.

Unlike earlier, where there might’ve been some concerns regarding her doing it, now he was commanding her.

Su Ah swallowed as moisture began to gather between her thighs again. Ah, fuck!

Still, she lowered her head obediently, with her red lips inches away from the glistening head. Not that she had much of a choice, with his hand clawing at her scalp so urgently.

The scent of arousal hit her nose—was that his pre-cum?

She stared at the flared tip of his member, transfixed.

It looked delicious. Would it taste delicious as well?
