Hanging out together became a normal thing for you and Wonyoung. After the "book bonding" incident happened a few nights before, you and your little sister became more attached to each other literally.
There are nights when Wonyoung visits your room just to browse your shelf filled with erotica and read them until it is time for her to sleep. Sometimes, you will bring the books into her room instead and read them together, not forgetting to be touchy and even have sex when things got too spicy.
Just like tonight you entered Wonyoung's room, carrying a bunch of erotic stories you handpicked yourself for her to read. You already knew what kind of kinks and porn genres she likes, so this mere task of picking what she will enjoy reading is easy for you. Placing the books on the nightstand, you removed your shorts and boxers before scooting beside Wonyoung, who's currently busy on her phone reading some fanfic stories on a popular website. Jealous that she didn't even say hi, you took the phone out of Wonyoung's busy hands, making her pout cutely.
"Oppa! I am not done reading that one yet. I want to go finish the story first." Wonyoung whined but you just pecked her lips, softly caressing the back of her hair.
"You promised to spend time with me tonight, remember? Now strip off your clothes and read with oppa. I brought you some new books I'm sure you will enjoy."
Wonyoung unwillingly hopped out of the bed and stripped her pajamas off, tossing them near the bed so she can easily locate them later. You positioned yourself on the upper part of her bed, back against the headboard with Wonyoung's pillow supporting your back. Your legs are splayed on her mattress, spreading them a little to your comfort. Pushing your hips forward, you stroked your dick into full hardness while watching Wonyoung strip, not like seeing her going nude isn't enough to give you an erection.
Your sister crawled back to the bed, going from the bottom up until her face is just a foot away from you. You cupped her soft cheek and pulled her closer, kissing her again tenderly as she slowly straddles your lap.
You and Wonyoung moaned when your erect cock pressed against her clothed womanhood. The heat and dampness of her crotch is such a turn-on, always calling up for sex whenever it is in touch with your dick. You grabbed Wonyoung's slim waist closer using both hands, pulling her body until it is resting on top of your chest.
Slithering your hand down from her curves down to her ass, you quickly fondle her luscious plump cheeks, groping them firmly while pressing her hips to assist Wonyoung's little grinding.
"YN oppa~ you said no~ sex today~" Wonyoung whined out between the kisses.
You only giggled and let go of your sister's lips, letting her catch a breath for the amount of oxygen you sucked out through her delicious mouth. "I know baby, but I want some cockwarming too."
Wonyoung sheepishly nodded and turned around. She already knew what you meant by cockwarming and also found a way how to enjoy it. Taking your cock using her soft slender fingers, Wonyoung stroked you a little while pushing her ruined panty aside. Sliding your bulbous glans against her slippery slit, she finally managed to find her womanhood's entrance and slowly sunk down.
You and Wonyoung moaned softly as she takes your length inch by inch. Wrapping your arms around your sister's waist, you help her sink herself further until you are balls deep inside her, sitting her ass on your hip.
You snuggled your head on Wonyoung's neck, kissing and nibbling on her skin to help her body stabilize after taking your whole girth without adjusting, though it is just an excuse to take a whiff of her natural scent.
"Oppa, stop it. It tickles~" Wonyoung giggled as you lick the bottom of her chin.
Stopping teasing your sister, you followed her request and took a book for her to read. Wonyoung gladly took it from your hand and laid down on her stomach, splitting her long slim legs perfectly as she goes to what she called a "comfortable position", reading while warming your cock inside her.
Wonyoung's lewd position made you choke on your own saliva. Her ass looked fuller, so plump and juicy while being covered by her thin cotton panty. Even her ass cheeks ate the fabric, letting you show the shape of her southern valley. You took the deliberate on fixing her panty for her, watching her cute ass ripple from the release.
"W-wonyoung... Are you okay? Isn't it painful for you to lie down like that?" You asked Wonyoung with concern, almost choking mid-sentence.
"It's fine, YN oppa. I actually found it better this way~" Wonyoung replied, bouncing her hips a little to tease your dick.
Your body jerked on an impulse, hands and eyes was trying to look for something to hold on to. Wonyoung shook her hips a little, letting you feel a different kind of tightness coming from her pussy. You swear to someone up there that Wonyoung is doing this on purpose- that your little sister clenches and relaxes her ass to squeeze your throbbing cock inside her.
Trying to ignore Wonyoung's playful antics, you took a different erotica book from the nightstand and start reading your own story. You flipped the pages and laid the spine of the book between Wonyoung's ass cheek, using her butt cheeks as a book holder as you read.
It should be a warm relaxing night for the both of you, but as you flip through the book, reading lewd stories and paragraphs on each page, you can feel your lust burning stronger, getting hornier to the point you don't even understand what you are reading anymore.
Unbeknownst to you, Wonyoung already feels the same, causing her hips to move on their own and use your dick inside her to fulfill the desire she wants to experience while reading erotic stories. Closing the book and putting it aside, you held Wonyoung's legs and steadily thrust your hips, subtly fucking Wonyoung's pussy.
"Ahh~ YN oppa... I thought you said no sex tonight...". Wonyoung moaned out a little, trying to pull her hips away from you but you just pulled her back.
" I know, Wonyoung... I know..."
Though your mind spoke on its own, trying to be true to your words, your body tells otherwise. The carnal desire to pound Wonyoung is getting stronger, to fuck and breed your little sister in this incestuous act.
"Oppa, please... I'm trying to read here..." She whined out again, but her voice turned into a plea for you to continue than leave her alone.
Fuck it, you thought, as your control over your decisions went to the other head after it felt Wonyoung's squelching cervix. You pushed Wonyoung forward using your hips, refusing to break the connection between the two of you until she was in a prone position. Snapping the hook on her bra, your hands slid underneath Wonyoung's body and cupped her perky boobs.
"YN oppa... Mhhh~" your little sister released a throaty moan after feeling your palms massage her boobs.
"Shut up and read Wonyoung. I thought you are trying to read..." You growled into her ear, nibbling on her earlobe, and its back on your way out.
"N-ne oppa... Jake scoots his-ahh~ head on Nicole's neck... Latching his lips on her skin to leave a mark..." Wonyoung read out the story between the moans.
Knowing the story at the back of your head, you are replicating what Wonyoung reads in the book she's reading. Snuggling on the crook of her sexy neck, you searched for Wonyoung's sensitive spots and lick them, kissing them softly until a faint hue of red marked her skin. You swept her hair towards her right shoulder, licking and kissing the nape down to her gorgeous back.
Getting the feel of what she was reading, Wonyoung's excitement pierced through the roof. The fluttery feeling of butterflies on her stomach and vagina is overwhelming- so cute yet hot at the same time.
Your rough hand reached lower, sliding from her chest down to her sexy abs to finger her little belly button. Wonyoung tried to curl up into a doggy position, ass up in the air and arching her back but your weight keeps pressing her down.
"YN oppa... Faster please..." Wonyoung cried out a little, feeling the snail-like pace of the progress of sex unlike when you two fucked like bunnies before.
"Faster what, Wonyoung? Didn't I tell you to read? Should oppa stop?" You sternly threatened, making Wonyoung look at you with her ready pleading eyes and shaking her head.
Wonyoung went back to reading, voice cracking on every sentence as her moans tried to get ween her words. While your hand that was left on her breast went to the other to give it the same treatment, your hand on her stomach trailed lower, finally greeting Wonyoung's wet twitching clit that was asking for some attention.
Immediately after finding the swollen nub, you held it between your thumb and index finger, giving it a little pinch and tug. Wonyoung yelped out loud from the sensation, forcing you to let go of her boobs to cover her mouth instead. While her body is still twitching from the stinging yet delicious pain of twisting her clit, you scooted closer to Wonyoung, trying not to laugh.
"Tone down your voice, Wonyoung. You don't want our dad to see his little princess having sex with her brother, right?" You asked and she nodded.
You glided your thumb on Wonyoung's suckable lips as you free her mouth, patting her head softly. Going back to your business on Wonyoung's body, you resumed playing with her clit and boobs at the same time, flicking and pinching it with a gentler touch so she won't moan loud again. You leaned to her back and lick her shoulder, giving them hickeys that look like a rash so she can have an excuse if your parents asked where it came from
Wonyoung's body won't stop twitching as you still surf in and out of her slick wet hole. Her vagina keeps reeling you deeper, drooling over your cock and taking what's more than she could take. Her long sexy legs felt jittery, kicking downward on the sheets when your cock hits her sweet sensitive spots.
Sadistic it may seem, but you love how Wonyoung sobs and sniffles due to the deprivation of rougher and much livelier sex.
You looked over her shoulder and saw her tearing up, arms folded between her and the bed. Her hands stopped holding the book and rested them beneath her chin already, not that she can focus on reading anymore when you are enjoying her body. Her needy pussy keeps clamping hard around you, trying to pull you back as soon as you retract your hips.
Your hand on her boobs left her chest once again and focused on her luscious lips this time. Plunging both your middle and index finger to her drooling mouth, hooking them to the side of her lips, Wonyoung immediately licked the digits willingly, coating them with her sticky translucent fluids and sucking them back.
You watched how Wonyoung's tongue slid between your fingers, serving them like it is your dick invading her oral cavern. You specifically enjoyed when you made a little gap between your middle and index finger, letting Wonyoung push her slimy wet tongue in between and letting you feel its softness. She looks so cute and sexy at the same time. A perfect girlfriend on the bed, only if she isn't your sister.
You pulled your fingers out of her mouth and she lets her saliva dripped out like honey, creating a strand that connects your fingers to her lips. Rewarding her for her wonderful show, you sucked your tainted fingers in front of Wonyoung, savoring her sisterly taste.
"Oppa, please... Wony wants to cum so bad... Sorry for being such a bad princess, YN oppa... Please fuck Wony already and my cum..." Wonyoung pleaded desperately, calling herself using her name that makes her look cute like a baby.
"Are you that close, Wonyoung? Should I pound your ass hard until you cum?" You asked and she nodded her head eagerly.
Fulfilling her request, you tucked her hair behind her ear and gave her a quick peck on the cheek. Your hand on her clit raised to hug her slim sexy waist, probing her ass higher. Grinning, you said "Hold on tight, Wonyoung. Oppa will fuck you good."
Buckling Wonyoung's hips and pulling them closer, you start pistoning her needy pussy with no holds bar. Wonyoung almost moaned out loud as the pace of your thrust went from snail-pace into a jackhammering one, making you cover her mouth immediately even if it labors her breathing. You tucked your head into her shoulder, biting into her marvelous skin and sucking hard to drown your groans.
The bed creaks loud at this point, the headboard keeps banging on the wall and your parents would probably run upstairs to check Wonyoung's situation if they are not heavy sleepers. Your little sister's toes are curling to delight, choking into her spit and moans as you cover her mouth shut. You might be going rough to Wonyoung, but she knows you are doing it to satisfy her needs.
You pulled Wonyoung's hips higher, pounding her pussy until you reach her deep cervix. your hand on her waist slides through her abs, continuing down to her leg and lifting it higher, positioning Wonyoung into a hotter position. Her chest starts heaving heavily, panting hard with her body twitching every now and then. Wonyoung's walls are even pulsing around your cock, and her pussy is getting extra slick and dripping.
"Are you close, my little Wonyoung? Are you gonna cum soon?" You asked endearingly. Wonyoung could only nod fast with her eyes shut tight. Kissing and taking a scent of Wonyoung's sexy nape, you trailed your wet lips from her neck to her cheek. "Cum, Wony. Cum for me, my little princess"
You released your hand from Wonyoung's mouth and replaced it with your lips, swallowing every squeal and moan your little sister voiced out. You then reached down to her clit to rub it feverishly with your fingers, sending out another jolt package of pleasure to Wonyoung's body.
Feeling crazy is an understatement of what Wonyoung feels right now. She wanted to curl up into a fetal position or close her spread legs at least, but having you in between them and giving her pleasure contradicts what she wants. Your sudden change of thrusts, coming from short and fast to long and deep ones doesn't help either. The wet sloshing sound of her pussy getting railed by your huge cock and the wet slapping sounds of your hips clashing together sound so lewd and erotic, hypnotizing Wonyoung's body to receive more pleasure.
All of the sudden, Wonyoung felt her stomach tightening- almost having cramps. She parted from the kiss and starts moaning out loud, ruining her modest princess image.
"YN Oppa!~ I'm cumming!~ hnngh!~" Almost like a whine, Wonyoung moaned out.
You rubbed her clit faster, fucking her with all of your strength until you feel a gush of warm sticky fluid on your crotch and thighs. Wonyoung arched her back beautifully, hands pushing herself up while her body is twitching uncontrollably. This is one of the messiest yet best orgasms Wonyoung had, and you are helping her all the way.
Your hips didn't stop moving even if her pussy is technically choking you out right now. Adding slaps to your rubbings on Wonyoung's pussy, you can even feel and control her messy squirts and tightness around you.
Wonyoung came for almost a minute before she flopped back down to the bed. Her eyes are out of focus, body jolts every now and then as the residue of her intense orgasm is still running through her nerves. You slowed down playing with her clit and your thrusts, still giving her the pleasure but not extensively to the point of taking advantage of her sensitive state.
"Are you okay, Wonyoung? God, you didn't tell me you can cum like that." You patted Wonyoung's hair, praising her for her wonderful orgasm.
Wonyoung exhales deeply, looking at you with a soft smile on her lips. "I didn't know I can squirt like that too, YN oppa. I haven't came like that before, even when I'm touching myself."
You pulled out of Wonyoung's pussy and saw the stickiness of her translucent cum, almost like someone played a prank to glue the two of you together. You hooked your arms underneath Wonyoung's sweaty pits, pulled her into your embrace, and removed the rest of the clothes from her body. Wonyoung felt your dick still standing hard pressing against her ass.
"Oppa. You are still hard and didn't come yet." Wonyoung asked in worry with her sweet voice.
"It's fine, Wonyoung. I can take care of myself. You should rest." You replied but Wonyoung shook her head.
Pushing you down until your back meets the sheets, Wonyoung straddled your lap and took your dick, pushing it back inside her still-sensitive pussy- making her squirt in the process.
"Wonyoung... You should rest... I can masturbate to relieve my boner..." You spoke while moaning between your sentences.
Wonyoung only shook her head, pouting cutely. "You can't, YN oppa. I must make my brother cum since he made me cum too."
Sitting on her knees and setting her legs astride, Wonyoung bounced on your hard-standing dick with glee. Her soft yet veiny hands held your shoulders, balancing herself while riding you but you took them and held hands together instead.
"Are you okay Wonyoung? Does it not hurt when your hurt when you ride me after your orgasm?" You asked uneasily, which you earned a firm shake of the head from Wonyoung.
"It stings but I like how it stings, Oppa. It's like when you tease my clit for being naughty yesterday."
"I really have such a good little sister~ mhhhh~ I love you, Wonyoungie~"
"I love you too, YN oppa~"
The two of you confessed to each other. Sitting back up, you released your hands from Wonyoung to hug her, pulling her close to make out with her. Wonyoung hugged you back by the nape, resting her arms above your broad shoulders. Your tongue licked Wonyoung's delicious lips, asking her for an entrance which she gladly did. Gaining access, your wet organ quickly finds its lover, dancing inside the enclosed two wet caverns while exchanging each other's essence.
Wonyoung giggled between the making out as you are getting a little aggressive. Liking how you kiss her, she hopped herself faster, taking your cock deeper inside her puffy cunt. Having an experience in dancing and pilates, Wonyoung uses her life skill to grind on you, rolling her hips fluidly which you found so fucking hot.
The incestuous affair is getting its second wind. Holding Wonyoung's nape with your forearm aligning on her back, you slowly lay your little sister down on the bed, switching positions with her until you are on top. Taking both of Wonyoung's legs to wrap around your waist, you start galloping at a much calmer yet fast pace, giving Wonyoung a milder kind of sex.
Giggles and moans are exchanged between the two of you. Staring into each other's eyes, you can't help but adore Wonyoung's beautiful face, especially her lips which keep calling you out for another kiss. Wonyoung's hands roamed to the back of your head, pulling you for a much closer deeper kiss while your hands are groping her cute firm ass.
"I'm close again, YN oppa~ I'm gonna cum~" Wonyoung announced as parted from your lips.
"Me too, Wonyoung... Let's cum together..."
Picking up the pace of your thrusts, you gallop faster and fuck Wonyoung's pussy. It didn't take much time for you to reach your peak since you are already at the edge. Wonyoung hugged you tighter, snuggling her face in the crook of your neck, and whimpered as she came for the second time. You also felt your balls getting heavier, pulling just in time to shoot your fat thick load on Wonyoung's stomach. Ropes and ropes of cum landed on your little sister's abs, filling her little belly button and spreading a good icing on her buns-like abs.
"Oppa! Why you didn't cum inside me? I was waiting for you to give me a creampie!" Wonyoung whined and pouted, earning a soft peck on the lips from you.
"It is hard to clean up if I came inside you Wonyoung. Besides, I don't want you to be addicted to creampies. There's a limit on what pills could do and I might accidentally get you pregnant one day." You caressed your sulky sister's cheek to calm her down. It seemed to work since she just nodded and accepted your excuse.
After helping Wonyoung clean her cummed body and ruined sheets, you opened the windows to let the scent of smell come out of her pretty princess-like room. Seeing her tired and sleepy, you helped her wear her pajamas and swept her legs, carrying her bridal style.
"YN oppa. What are you doing?" Wonyoung asked in confusion.
"Sleep in my room tonight. I can't let you sleep on a wet bed, would I?"
Wonyoung blushed from your sweetness and curled in, letting you carry her back to your room which she is familiar with. Laying her softly on the bed, you joined beside her and tucked under the blanket, making you and Wonyoung cozy. You hugged Wonyoung by her waist and pulled her closer, spoon-cuddling her.
"Oppa... Do you think our parents will be mad if they know what we are doing?" Wonyoung concerns asked.
"I don't know Wonyoung... but I will stay with you forever no matter what will they say..." To be honest, you know they will be mad at you for laying a finger on your sister. But what you are afraid of more is that they will denounce you as their son and take Wonyoung away from you.
"I will stay with you too, YN oppa. I don't know if I can live without you..."
Wonyoung turned around and faced you, giving you a reassuring kiss and a promise you will hold too. You smiled softly and kisses her back, hugging her tighter into your embrace.
"Should we sleep now, oppa? I want to wake up first than you so I can suck your morning penis." Wonyoung smirked, almost like challenging you.
"I doubt you will wake up first before me. I will make sure you will wake up with my dick fucking your ass already~"
"So that means the first to wake up will fuck the other?"
"Mhm. The first to wake up will fuck the other."
Wonyoung pumped her fist in excitement and turned back around, scooting her body closer fit to your embrace.
"Anticipate your morning blowjob, YN oppa. Goodnight~"
"Anticipate your morning creampie too, Wonyoungie~ goodnight~"
