Sisterly Bonding

The sibling bond is a magical thing.

They could hate each other, but still love each other. They could be tearing at each other’s hair, then in the next breath be defending the other when it matters. Most siblings are like that—each other’s most bitter rival, all while simultaneously being each other’s rock to lean on. However, the degree that each sibling pair leans on each other differs. Every pair is different in their own way.

With the pair in front of you, there are no words to explain it, but many actions to show it.

“Chaewon-unnie, it’s my turn…”

Kim Chaewon rises from your embrace, a soft smile gracing her features. She caresses your face as she gets off your body, and her soft groan of pleasure escapes her lips when your hard cock slides out of her freshly fucked cunt, hitting your skin with a ‘Plop!’. A mixture of Chaewon’s juices and your semen stains your crotch from when she squirted all over you, and she adds to that mess when the load you left in her immediately bubbles out and drips onto your cock.

“You came so much, Minseok-ah…”

Chaewon leans over to kiss you on the cheek, and then her hot breath grazes your ear.

“Now do the same for my cute little sister, won’t you, baby?”

You groan when she brings it up, and the sight of said naked little sister eagerly yet patiently waiting for her turn after watching her older sister have sex with you leaves your cock twitching.

“Come on, Minjeongie.”

Chaewon calls for her sister so nonchalantly that you’d think she was just getting the younger girl’s attention on a normal day. However, this situation is the same, yet entirely different; Chaewon does call for her sister’s attention, but not for any normal reason—she’s sharing her boyfriend with her blood sister. Minjeong has yet to lose her virginity, and Chaewon wants to help her through her first time.

“Remember what I said, Minseok.”

Chaewon pulls on Minjeong’s hand, and the younger girl follows. She crawls over your body to straddle you, and you watch as your girlfriend guides her younger sister. Minjeong’s confusion at her sister’s words to you is written all over her face, but she doesn’t ask.

“Minjeongie, look. Look at how hard Oppa is for you.”

Your cock twitches when Minjeong looks. Your eyes rake across the younger girl’s body—petite breasts sized just nice for a handful, smooth milky skin almost akin to a doll’s, a slender waist you’d love to grab, and the cutest outie pussy you’ve ever seen, clean shaven. Minjeong is the dream girl of so many boys at her school, and here you are, the chosen one by her older sister to be able to fuck such a goddess.

“Are you excited?” Chaewon caresses her sister’s cheeks, before her hand falls to gently knead her younger sister’s breasts. The younger girl moans sharply, and your cock twitches again, white precum dripping from the tip at the sight in front of you.

“I-I’m so excited, unnie…”

“You’re such a good girl.”

Chaewon’s lips meet Minjeong’s for a kiss. With practiced ease, Minjeong reciprocates as her lips move against her older sister’s, and you’re more than happy to play voyeur as you stare at both sisters kissing each other. Chaewon’s tongue slides against Minjeong’s as they deepen their kiss, and the elder’s hand slides down to rub the younger’s clit, the wet sounds of Minjeong being masturbated going straight to your cock. You can’t resist slowly jerking off just to alleviate the pressure.

The soft sounds of Minjeong moaning in pleasure only gets louder when Chaewon breaks the kiss to trail her tongue along her sister’s neck, then plant soft butterfly kisses in a trail as she straddles your legs behind Minjeong. When she takes her place behind her sister, she pulls her drenched fingers out of her pussy, strands of Minjeong’s slick clinging on to the digits as Chaewon raises her hand to her lips to taste her sister’s pussy.

“Mm, Minjeongie, you taste so good.”

“Really, unnie?”

“Of course, baby. My little sister’s pussy always tastes the best."

You curse at the sinful words that come out of Chaewon’s mouth. This relationship wasn’t something you weren’t aware of, but for it to be mentioned so casually, and the pure taboo of it in general has your mind and body working overtime with lust.

"Minjeong-ah, come taste yourself—mm, yes, good girl, that’s right…”

Ever the obedient little sister, Minjeong licks the remnants of her slick off Chaewon’s hand at her sister’s command. She smiles sweetly at the praise, an expression you don’t expect to see in the bedroom, but welcome nonetheless. However, the lust in Minjeong’s eyes returns instantly when her eyes lock on you stroking yourself, along with her nervousness.

“Unnie, I’m scared…”

“There’s nothing to be scared of, Minjeong-ah. It doesn’t hurt at all—in fact, you’ll feel so good that you’ll forget about being scared. It feels so good you might even get addicted to it, but you shouldn’t, okay?”

“O-Okay, unnie.”

“Good girl, Minjeongie. Come, follow unnie’s instructions.”

Chaewon pushes on Minjeong to move forward on her knees, right above your cock. That’s your cue to stop pleasuring yourself, and you let your cock fall back as your girlfriend primes her sister for her first cock.

“Go on, hold on to Oppa’s shoulders.”

Minjeong hands land on your shoulders, and you instinctively grab her waist just as you would with Chaewon. Minjeong flinches in surprise before she relaxes into your warm touch.

“Unnie, Oppa’s hands are so warm.”

“They are, aren’t they? I love those big strong hands."

Chaewon reaches beneath Winter, her hand grasping onto your hard length. She pulls it up and strokes you a few times as she kneads Minjeong’s ass. With a giggle, she slides your cock right along Minjeong’s slit, drawing a groan from you and a yelp from her. She continues sliding your cock up and down along her sister’s slit, Minjeong’s slick slowly dripping down your cock over hers from earlier.

"Hold it there, Minseok, baby. It’s time for Minjeongie to take her first cock.”

You oblige and watch as Chaewon gently guides Minjeong.

“Minjeongie, relax, baby. Just sink yourself down on Oppa’s cock slow and gentle, okay?”

“O-Okay, unnie!”

You groan when Minjeong shifts, and you begin to curse up a storm when she begins to sink down, as per her sister’s instructions. Both you and her release loud moans as your tip disappears into her tight virgin pussy. Minjeong is so wet and so tight that you’re already about to blow your load with your cockhead just in her.

“Fuck, she’s so tight, Chaewon!”

“Oh, is she, baby? Does it feel good?”

“So fucking good, fuck!”

Minjeong doesn’t speak—she can’t, not with the overflowing pleasure coursing through her system. She gasps, whines, moans, and whimpers as she sinks herself further and further onto your length. Her cunt stretches to accommodate your girth, and she forces herself to take more and more of your cock into her. Inch after inch of your cock gets engulfed by Minjeong’s wet walls, and you can’t resist shallowly thrusting up into her to speed up the process. You hold Minjeong in place and push into her bit by bit until you feel her crotch press flush against yours. Minjeong releases a long sultry moan and falls against your body, her breaths heavy, as are yours.

“Congratulations, Minjeongie, you’re not a virgin anymore.”

Chaewon runs her hands along her sister’s body to soothe her, and she leans in for a kiss with you. Both of you begin a short makeout session while Minjeong recovers, only breaking the kiss when she whines in protest.

“Unnie, it’s my turn with Oppa!”

“Ah, sorry, Minjeongie. He’s all yours.”

Minjeong pouts, but the expression is soon replaced with pleasure when she shifts against you, tentatively lifting herself off your shaft. You groan when your shaft leaves the warm embrace of her cunt…
