Side Story 5) Siblings’ Tale 13

As it began, Daeun’s hands started moving. She pressed down on the nipples she’d already been toying with, rubbing them up and down as she began masturbating. Dajun sat on the bed with a smile, watching the sight. His younger sister desperately stimulating her nipples to suck his cock…

The fact that she was his sister did bother him, but it was outweighed by how incredibly hot she was. His sister was just too sexy-both her face and body.

If he really thought about it, appearance-wise, Daeun matched his ideal type better than anyone. Even her personality was perfect-acting tough but actually being hopelessly weak, unable to hide it, which made her adorable.

‘Well, it’s still a bit…’

But the fact that she was his sister was a huge barrier. Even if her face and body were fine, if someone asked if he’d date her, he’d hesitate. Maybe it was because he’d already seen every embarrassing side of her, or maybe it was just the natural aversion to incest.

‘She’ll probably get a boyfriend eventually anyway…’

It was a shame, but he wasn’t completely hung up on it. He already had a girlfriend, and there were plenty of other girls around. This was just a playful little fling. Eventually, she’d meet other guys, and this would just become a memory.

That’s why Dajun had no problem maintaining this kind of relationship. He didn’t think too deeply about it. He just had a sexual partner, and it happened to be his sister.

That was the extent of his feelings.

But Daeun was different. What Dajun hadn’t considered was that his sister had no experience with men at all. He was the first man she’d ever been with. And having her first man be her own brother had completely ruined her.

The bar was set so high that no other man could possibly compare. She might deny it now, but the emotions swirling inside her were unmistakable. If her brother told her to devote her entire life to him right now, she’d be dripping wet and ready to give him everything.

As proof, she was diligently following his absurd command to reach nipple orgasms seven times in ten minutes just to suck his cock.

It was ridiculous by any normal standard… Though maybe Sebin or Daeun could pull it off. Either way, it wasn’t something a sane person would do.

“Nnghh…♡”

The way Daeun moaned shamelessly as she came was obscene. Anyone who knew her usual self would be utterly shocked to see her like this.

Whether it was unfortunate or fortunate, it wasn’t a problem for Dajun. In fact, he liked it even more. They were siblings, so he’d already seen all her embarrassing sides, and he knew she was just putting on an act at school.

That’s why this stupid, lewd display only turned him on even more-it wasn’t a downside at all.

“Hhhaaah♡ Oohh…♡”

Her desperate, trembling orgasms were kind of cute, actually. Dajun hadn’t even seriously expected her to manage seven orgasms in ten minutes-he’d just said it as a joke.

He’d planned to tease her a little when she failed, then fuck her properly, but seeing her current pace, he was starting to think she might actually succeed.

Checking the stopwatch, about five minutes had passed. She’d already come at least three times. Considering that orgasms get easier after the first, it wasn’t actually impossible.

Amused, Dajun watched his sister with growing interest.

“Eek, hiiih…♡”

He almost wondered if her nipples would stretch out from all that pulling. Daeun’s pretty, pink nipples were being tortured relentlessly. But they wouldn’t deform from just this much. If they could, her pussy would’ve already changed shape after being pounded daily for the past month.

Yet Daeun’s pussy was still a soft, pale pink. The way it stayed tightly closed in a straight line made it seem like she was just born that way. Though it did loosen up a bit whenever his cock pushed inside. Guess she’s just naturally perfect down there.

Then, a ringing sound came from his phone-the ten minutes were up. Dajun turned off the alarm and looked down at his sister. Still desperately playing with her nipples, she wore a slightly panicked expression.

“How many times?”

“S-Six…”

Seems she failed, just barely. Dajun didn’t really care and set his phone aside. Either way, he should probably cum soon-he was pretty worked up himself.

But Daeun seemed to take it very seriously. With her face still flushed from orgasm, she made a pitiful expression, crawled forward on her knees, and looked up at his cock.

“C-Can’t I try one more time…?”

“……”

Fuck, that’s hot. Daeun fidgeted with her nipples, and when he didn’t respond, she leaned forward and pressed her cheek against his cock, still watching for his reaction. The way she acted was unbelievably arousing.

But if he gave in too easily, it’d ruin the fun next time. Suppressing his urges, Dajun sat her back down.

“Fine. Then this time, three clit orgasms in one minute.”

The moment he said it, Daeun’s hands shot down to her clit. But she couldn’t even grip it properly, just rubbing frantically while whining-it was a ridiculous sight. Still, even for Daeun’s body, three orgasms in a minute was impossible. She only managed two before time ran out.

“I-I can do it♡ Hhuuuh…♡”

Dajun’s torment continued. He kept giving her impossible tasks, making her cum over and over. Once, she almost succeeded, but he ruined it by tapping his cock against her, deliberately sabotaging her.

Then, in the middle of all this absurdity-

“Hhiiit…♡”

Daeun’s head was suddenly grabbed. Dajun, unable to hold back any longer, had started jerking off and was about to cum.

Daeun obediently let herself be used, feeling the taste of his cock sliding rapidly in and out of her mouth.

After several wet thrusts and slurping sounds, Dajun pulled out and rested his cock on top of her head.

He came like that. Cum splattered over Daeun’s hair and back, the rest smeared across her cheeks. The sudden heat on her back sent her over the edge too.

“Hhhyuuu♡ Nngh♡ Uhh…♡”

The way she shuddered through her orgasm was obscene. Dajun wiped the last drops of cum on her thighs before leaving without cleaning up. He was more than satisfied.

It took Daeun several minutes to even stand up. Cum dripped from her hair and back, but she wasn’t in any state to care.

“Ugh…♡ You trash…♡”

She had no right to complain while her pussy was still twitching. Plus, her expression was that of a girl hopelessly in love.

Daeun forgot to clean up and just kept fingering herself, lost in thought. Had she always been into guys like this? Thinking back, all the guys who’d approached her had been overly nice. But then again, no guy would dare be rude to a girl like Daeun.

Because of that, she’d never felt real excitement before. But now? Even though she was being treated like an onahole and humiliated, her heart was pounding.

To think she’d get turned on by such trashy behavior. She must just have terrible taste.

She never understood when her friends talked about liking bad boys, but now it made a little sense. Of course, the “bad boys” her friends meant were nothing like what Daeun was imagining.

“Ugh, what do I do…?”

But there was one problem. It wasn’t that they were siblings-it was that her brother had a girlfriend.

Sure, the idea of him enjoying dates with her while treating Daeun like a disposable toy was part of the thrill. But that would only last a few days. If it kept going, it’d start to hurt.

“Do I have to seduce him…?”

There was no other way. Daeun sniffed the lingering scent of cum as she masturbated for hours, finally collapsing from exhaustion.

“Nnghh…♡”

Waking up, the room was a complete mess. Her body was sticky with her own fluids and his cum, and the pads on the floor were soaked through, excess liquid pooling around. Still, it was better than nothing, though she probably needed two pads at a time now.

The mirror showed an even worse state. The reflection was of a girl who looked like she’d spent the night in wild mating-though in reality, all she’d done was suck her brother’s cock and get splattered with a bit of cum.

He hadn’t even fucked her properly. What a trashy brother. If he was going to treat her like an onahole, he should at least take responsibility and fuck her properly instead of just making her masturbate all night. Now she was in heat from the moment she woke up.

In the end, she pulled out one of her brother’s hidden shirts and buried her face in it. Just a little longer, just a little more.
