136화 26. 언니는 이런 거 좋아할 텐데 (4)
**Episode 136, Chapter 26***Sister would love this kind of thing (4).*8.5/10. If I had to give him a score, that's about all he deserved, but that doesn't mean he was without flaws."You don't really need to practice that kind of thing.""...My fingers...""First, take your fingers out..."*One.*He's clueless.A normal person would have figured out by now why I'm doing this, but that idiot still thinks this is just practice.*Please, just think about what's on your neck.**What kind of saintly sister would practice sex with you for her sister's sake?**Does that even make sense?**I'm just doing this because I want to cheat on Sister behind her back.*This practice is just a flimsy excuse.*You idiot.*"Hey, damn it, don't wipe it on your thigh...! You have a towel!""It'll just get sweaty again soon anyway. What's the big deal?""That's still gross... ... *Eek?!*""Stop struggling. You'll fall.""W-what, are you saying we should go to bed like this...?""Yeah."*Two.*When I first met him, I just thought he was a nice guy. But that's only on the surface—he's actually a total sex fiend.Come to think of it, he's been like this since we first started practicing together.He'd call the sister working at the convenience store and ask her for sex, saying he'd never do that... but then he'd call that guy he played games with yesterday and ask him for sex. He's got some secretly perverted tastes, you know?*As similar to me as...?**If even the slightest sound leaks through the mic, I'll be caught instantly. Why would he insist on doing this?**Maybe he wants to see me struggling to hold back my voice?**Or maybe he wants to see me finally give up and pant, moaning into the mic as I climax? ...**Ugh.**You perverted bastard.**Disgusting.**Ugh.*"L-Let me down...! I can walk there myself!""...You were flinching so much earlier.Really?""It's right in front of me, what's so hard about that...*Fuck...*""...Fine, I'll put you down. Go to the bed."But, as the man I gave a solid 8.5 to, he had a few advantages that outweighed his flaws."...Hey.Seo Woo-jin.""Why?""...You know, that thing where you make someone wait?""Yeah.""...I think it's worth practicing at least once...""...Is that really necessary?""I told you.Just fucking me like a beast from start to finish makes you sound like a total virgin.""When you called yesterday, I didn't hear you moaning...""I heard you.I heard you.""...Yeah.""...You.You don't know what kind of noises you make when you secretly masturbate in my room, do you?""...."One.You're so clueless."Even with the door closed, it echoes through the whole living room? ...Louder than what I heard on the phone?""....""So what does that mean?It means masturbating with your fingers felt better than the wild sex we had.Got it?""...Mmm."*He's so clueless it's almost pathetic.*Of course, I've never heard my sister masturbate.Unless she's gone completely insane, she wouldn't masturbate loud enough to be heard in the living room when I'm right here at home, right?So all she did was tell a lie that reeked of desperation.Seo Woo-jin..."...Alright.If that's how it is."He's so clueless.It's so easy to manipulate him as I please. ...It's not just men who can drive others wild, you know?Women can drive men wild too.And after I've driven Seo Woo-jin wild enough... when we start real sex practice later... ...I'll break him completely.*Thump, thump, *thump*...*Heh."Oh, right...Stay here for a second.""Why?Again?""Just stand there if I tell you to...!""...*Sigh*...*Annoying.*"....""....""...*Hey*.""...."And Seo Woo-jin's second advantage."...*Stop it*.*It's gross*.""...*Whatever*.*I just washed up, how could it be gross...?**And I'm your sister, remember?*"....""If it were Lee Ha-yoon, she'd fucking love this.Right? ...She'd probably love it even more if I forced her.""....""So of course I have to practice this stuff.If I'm gonna fuck Lee Ha-yoon like a dog, whether it's her mouth or her pussy..."*His libido is stronger than I thought.*"...*Pfft*...*Look how hard you've gotten...**I'm not your girlfriend, I'm your girlfriend's little sister, you know.**Heh heh...*"....""Ah, never mind.*Hmm~*...*What would my sister say if she saw this...?*"....""...You must have been speechless.You probably got horny the moment you saw me and started sucking like crazy."As I knelt quietly and cautiously rubbed my face against Seo Woo-jin's underwear, his cock immediately twitched.Glancing at Seo Woo-jin, I started lightly kissing his bulging cock. He naturally placed his hand on my head...Without even asking, he firmly pulled my head toward him...His sex drive is intense."...Hey, your hand movements seem familiar...""....""Did you really do this to Sister yesterday too? Like... forcing her head down to suck your cock?""It wasn't forcing...Just a little.""...You two are really perverted.""Yesterday was your first time, and you went straight for that kind of play...""...""Anyway, you did well. Lee Ha-yoon would love that kind of thing.""...Yeah. She did.""Sister, she'd probably love dog collars too, right? Like being railed from behind while a guy yanks on a leash...And...Oh!And getting fucked while he strangles you is pretty..."I'll keep that in mind for later.So, Jiyoon-ah... ...That...""......Ah.Yeah.""...""I get it, so stop pulling on the back of my head.You idiot.""...""Virgin bastard...Hmph..."For a moment, I was so excited I blurted out all of my sister's porn preferences.Kneeling on the floor, hands flat on the ground, I closed my eyes, eyes half-lidded, as I sniffed the scent of my sister's boyfriend's cock through her panties. *Sniff, sniff...**Ah, damn it.*I shouldn't be enjoying this.Still, it's a relief that it'll just look like I'm *pretending* to like it to Seo Woo-jin.After all, it's Lee Ha-yoon who's kneeling here, not me, right?I'm just the angel-like sister who supports their relationship.*Mmm-hmm.**...**Pfft...*I bit the slightly damp panties, slick from kissing, and pulled them down with my lips.What's hidden inside is so huge it's a little difficult, but... if I use my teeth, I'll manage somehow.The panties were caught on his glans, refusing to budge.I bit the edge with my teeth and yanked them down. ...Then, "...."Exactly the same as the last thing that had remained in my mind. ...Looking again, it seemed even bigger than before.A thick cock, veins bulging like taut strings.A scrotum obviously swollen with semen.It twitched above my face.And it reeked of arousal, slick with precum."....""...."I felt like I should say something, but the words wouldn't come.I wanted to sound energetic like Sister, saying, "Wow, look how swollen your cock is.*Pfft.*""So you wanted me to suck your cock so badly? You pervert?"Or maybe something more businesslike, "I'll stay still now. Think of me as your Sister and force yourself to give me head. If you feel like you're going to vomit, I'll tap your thigh."I'm not out of ideas, but...It's like... being overwhelmed...By just that cock."...*Gack*...""...."I gave up on trying to say anything.Instead, I pressed my face against his glans and stuck out my tongue, making a *Gack* sound, as if even an idiot would understand.Ah.No.To take that much cock, I'd need to open my mouth wider... ...Wait.Hey, what if you suddenly force it in..."...*Gack, mmmph*... ...*Phew...*The cum, which had been all over his glans moments ago, now sullied my tongue.It quickly stained the roof of my mouth, and as if that weren't enough, he roughly thrust his cock into the narrow entrance of my throat, splattering it with cum.It felt like he was marking me as his property.My mouth filled with Seo Woo-jin's scent."Ugh...*Gack, cough...**Mmm...**Phew...*"I wanted to suck him hard enough to please him, but...It was impossible.Instead, I wondered if I should carefully lick the tip of his glans with my tongue, like in those adult comics, but right now, I could barely keep from pulling away, so even that was impossible.In the end, I just drooled on the floor, my tongue lolling uselessly.Seo Woo-jin's hand rested on my knee, and I was manipulated like a toy.He hadn't even gone halfway in, let alone all the way.*Ugh.**Ugh.*I gagged repeatedly.I was becoming his new toy, replacing my Sister.*Well, I guess.**Compared to Sister, I'm the newer model.**Seo Woo-jin would probably prefer this over the old one.**Pfft...**"Slurp, *phr...* ...**Ugh...**Ah.**So this is why tears come, even if I don't want them to, when he forces his way down my throat.*I blinked away the sudden blurriness in my vision and glared steadily at Seo Woo-jin, who was looking down at me.I heard somewhere before...Men like it when women give them a defiant look while they're performing fellatio.Especially when those women stare up with bloodshot eyes, tear tracks on their cheeks, and a look that says, *I'm going to kill you.*They apparently love that kind of thing.Well, it's a man's preference, but even as a woman, I think I get the general idea....The feeling of conquest.It's always the same in Western porn.So predictable."...."Was my prediction correct?When I met Seo Woo-jin's eyes, he was busy pulling at the back of my head. He gave me a faint smile, one I'd never seen before.His usual smile was just kind and innocent. But this...This was a smile that clearly showed he was looking forward to fucking me.At that smile, I foolishly squirmed my thighs and, with the tongue that had only ever drooled before, I diligently began licking the base of his cock.*So I am getting used to this after all.**After all, I've seen porn where they shove dicks down their throats so deep it's ridiculous.**If I didn't get used to it, that would be weird.*"Pfft, Hah...Phaaa...Ha... ...Why did you pull out?Suddenly...""...I thought you were suffocating.I just wanted to give you a moment to breathe.""Then I'll beat your thighs hard, so don't worry about that. Just shove your cock in my mouth. ...You coward.""....""Lee Ha-yoon... she's a masochist who likes to be ravished... ...*Ugh, *ack—...* *The dry, composed woman I saw earlier was gone. Now her cock was soaked in my saliva, a hazy ring forming mid-shaft.I gripped the base tightly with my fingers......and licked her swollen, throbbing glans, the one straining to cum. As I did, the thick, long cock brutally pressed down on my gasping breath......and shoved itself back into my mouth."Hah, *slurp*... ...*Mm...**Mmmph...*I couldn't breathe.Every time her glans slammed against my throat, I gagged uncontrollably.Even so, shy tears kept welling up and streaming down my cheeks.Still, afraid Seo Woo-jin might misunderstand, I even lowered the hand I had been pressing against my knee. ...I thrust my fingers into the vaginal wall, which had been busy making the floor sticky and dirty.My heart was pounding so hard it felt like my eardrums would burst, but unlike my sister, I wasn't particularly masochistic. Yet, this situation—betraying my sister behind her back, cheating with her boyfriend under the guise of practicing—was...*... ... ...**Mmmph. ...**Fck...*While my sister was happily playing with her friends, here I was, with his cock rammed as deep as I could take it, swallowing his semen, *glug, glug, glug*—this situation was......completely....My type.
