    Jungeun is curious about sex—how does it feel? Is it as good as other people say it is? So, Jiwoo helps her out, and if they accidentally make love, so what?

    1

    Author's note

    I think this was one of my best fics. For @midnightdancingsol.

    “Jiwoo-ah.”

    “Yeah, Jungeun-ie?”

    “How does sex feel like?”


    Kim Jiwoo and Kim Jungeun are said to be inseperable. Where one goes, the other will follow. If you looked up “sisterhood” in the dictionary, you’d find a photo of the both of them printed right below the definition. The trust they had in each other was unmatched by any other pairing, fictional or real. After all, you don’t cultivate a friendship for fifteen years and have at least a modicum of trust for the other.

    Most people wonder why the more stoic, reserved, introverted, and boyish Kim Jungeun would ever end up best friends with someone like the extremely extroverted Kim Jiwoo, who might as well have enough energy stored in her body to rival that of the sun. One preferred to stay at the corners of the cafeteria with her book, and the other could be seen zipping about to greet everyone exuberantly. Somehow, these two managed to make it work—Jungeun could be found trailing Jiwoo around with a polite nod to whoever Jiwoo wanted to meet, and Jiwoo would introduce Jungeun to people she otherwise would’ve never met if the bright puffball weren’t her friend. It was a well-functioning friendship, and both girls enjoyed that well.

    It was no secret between the both of them that Jungeun was the “pure” one—almost zero experience in anything regarding the love department, and Jiwoo was the “experienced” one—she’d had a couple one-night stands and a few flings under her belt. Jungeun knew that Jiwoo would answer any questions she had, which is why both girls were in Jungeun’s room on a Friday night after a long day of classes over in college. Both girls sit on Jungeun’s bed, Jiwoo on Jungeun’s right. The TV opposite them is paused on a frame of some drama series on Netflix.

    “Jiwoo-ah.”

    Yeah, Jungeun-ie?“

    "How does sex feel like?”

    Jiwoo falls uncharacteristically silent. She has answered many questions from Jungeun about the topic before, but this is the first time she’s been this forward.

    “It's… uh… really good. It feels amazing if done right, and it feels so euphoric.”

    “Hmm.” Jungeun nods, chewing on her bottom lip. That’s not the exact answer she’s looking for—it doesn’t really satisfy her curiosity. She wonders how to phrase it better in order to get the answers she wants.

    Jiwoo is no stranger to how Jungeun looks when the answer isn’t what she wanted. Her brows furrow and her stare goes blank as she goes deep into the recesses of her mind, rearranging the different thoughts that she has to produce the best method to get her answers. She chews on her bottom lip out of habit, and Jiwoo swears she can hear gears turn in Jungeun’s head. Jungeun also puts a hand under her chin and leans forward. She always looks cool in that mode—Jiwoo has never seen someone with a nicer thinking pose. Jungeun is pretty, super pretty, and so lovable.

    “But Jiwoo-ah, ‘really good’ and 'if done right’ doesn’t really…”

    “I know, Jungeun-ie. It’s really hard to describe feelings. I’m sorry.”

    “No, it’s okay. It’s fine.”

    Both girls fall to a silence. Jiwoo attempts to think of a better way to articulate the pleasure of sex into words, and Jungeun wonders if it’s even possible. The only option she can come up with is impossible to achieve, and while it might be the only way, she doesn’t really want to entertain that option. It would cause too big a change.

    “I can’t explain it at all, Jungeun-ah.”

    “It’s okay, Jiwoo. I’ll know it when I get there, right?”

    “Right.”

    Another silence. Jungeun knows Jiwoo isn’t going to let this question go just yet. Jiwoo is relentless in helping her friends out, and she’s done her best to answer every single one of Jungeun’s questions, no matter how dumb or personal they might be. She just hopes Jiwoo won’t propose the solution she refuses to entertain—she can’t do it with Jiwoo. Jiwoo is… she’s too good for Jungeun. Too good.

    “Jungeun-ah.”

    “Mm?” Jungeun turns to her right. Jiwoo’s serious gaze meets her eyes.

    “I’m not able to tell you, but since they’re sensations and feelings… I can show you.”

    Fuck.

    Jungeun seizes up, her jaw slack, body frozen mid-motion. She should’ve known better than to expect Jiwoo wouldn’t propose it. She’s never been one to keep things to herself—she blurts out her thoughts and wears her heart on her sleeve most of the time. However, this isn’t something Jiwoo should just be blurting out like that—Jiwoo essentially just propositioned her, just offered to maybe (okay, not really maybe, more like really) have sex with her best friend to show said best friend how sex feels like. A heavy blush explodes over Jungeun’s face, her ears tinged in the same shade of red. At the same time, her cock hardens in her pants, bulge slowly rising to tent the cloth. Jungeun unsubtly moves her hands to her crotch in an attempt to cover it up—she shouldn’t let Jiwoo know how much she likes the idea. Not at all, even if she thinks about it at night sometimes.

    “Wh-What do y-you mean?”

    “I can show you how sex feels like, Jungeun-ah.”

    Jiwoo has the same blush burnt across her face. Jungeun can tell she’s embarrassed and maybe a little ashamed at the suggestion—Jiwoo tends to fiddle with her watch, her pants, her shirt, whatever she can get her hands on as a distraction. This time, Jiwoo rubs the hem of her T-shirt with her thumbs, unable to look at Jungeun.

    “Do you mean… that you… and me…?”

    “How else?”

    Jungeun’s cock twitches hard in her pants. Sex with Jiwoo, a thought that Jungeun admits is a guilty pleasure of hers for a while now. Jungeun shamefully admits that many a night, she’s brought herself to orgasm at the thought of a naked Jiwoo spread under her, Jiwoo’s hole leaking Jungeun’s cum after a long hard round of sex. All imaginary, but Jungeun always wishes it is real.

    “But…”

    “I’m okay with it if you are, Jungeun. Only if you’re comfortable with it.”

    Jungeun isn’t sure. Her body screams “Kiss her! Touch her! Fuck her!”, but she hesitates. Sex with her best friend would change everything, and she’s not entirely sure if this is the right way. Surely there has to be a better way—Jiwoo doesn’t have to use herself like this. No, she should be having sex with someone she likes, not her best friend, and not because said best friend is curious. Not like this.

    “Jungeun-ah, I know you want it.” Jiwoo breaks into a giggle. “Your pants…”

    “Oh, fuckshitfuckfuckdamnit."

    Jungeun’s hands slid down to her sides while she was in her deep thoughts, and now her hard bulge stands tall and proud, almost poking a hole through her pants. She rushes to cover it up, but Jiwoo grabs her wrists to pull them away. Jiwoo leans in, her face just a few inches away from Jungeun’s.

    "It’s okay, Jungeun-ie. If it helps…”

    Jiwoo bites her lip, her eyes falling to Jungeun’s soft, round lips.

    “If it helps, I’m wet too.”

    What. The. Fuck.

    Jungeun is speechless. Jiwoo cups her best friend’s cheek with a hand, her thumb gently running circles on the smooth skin.

    “I’m okay if you’re okay, Jungeun. If you don’t want to, stop me right now.”

    “Wait. Please.”

    Jungeun wraps her hand over Jiwoo’s that rests on her cheek.

    “No, I can’t let you do this. You deserve to be doing this with someone you love, not me. Not because I’m curious. I don’t want you to sleep with me just because I wanna know. I can’t be selfish like that.”

    Jiwoo smiles.

    “But I want to, Jungeun-ie. It’s okay, because I want to do it with you.”

    Fucking hell.

    “You’re worried about what we’ll become after this, aren’t you?”

    “Ack—!”

    Jiwoo giggles. Jungeun panics. Fuck, nothing about Jungeun ever escapes Jiwoo’s notice. She knows too much about her best friend.

    “And you’re worrying about how it feels too, hm?”

    Fuck, Jiwoo goes two for two.

    “Don’t worry, Jungeun-ie. Nothing’s going to change. We’re still going to be best friends, and I promise it won’t be awkward at all. I promise, cross my heart, that nothing will change. You’ll still be my Kim Jungeun, and I’ll still be your Kim Jiwoo.”

    Jiwoo pulls Jungeun’s hand into hers, and she clasps her hands around it.

    “Besides, wouldn’t you rather be having your first time with someone you trust, like your best friend?”

    “Hmmggh…”

    “I know you wanna say yes, Jungeun-ie~.”

    Jungeun can’t find it in her to open her mouth to tell her that she really does want it, that she wants to be perfectly okay with it. That’d be too embarrassing. The shock and disbelief from the current situation is also a little too much right now, and against her will, she nods once. Jungeun wants this a lot—sex with Jiwoo sounds like heaven. Her first time with someone she can trust, with the person she knows she can trust. In fact, she really wants Jiwoo. She’s wanted Jiwoo for a while, but… what is it she’s feeling for her?

    “Are you sure?”

    Jungeun nods again, her lips thin. Jiwoo shifts closer, her shoulder against Jungeun’s, the mere brush of bodies setting fire across Jungeun’s skin. Jiwoo is perfectly calm, and she leans in to press a soft kiss to Jungeun’s cheek.

    “Relax, Jungeun-ie. It’s just me, your best friend. I’ll take care of you well, okay? Just trust me and enjoy the process.”

    “Okay.” Jungeun relaxes a little at Jiwoo’s reassurances. If there’s anyone she can count on to take care of her, it’s Jiwoo. It’s always Jiwoo.

    Jiwoo draws closer, her eyes flicking between Jungeun’s eyes and lips. Both girls can feel the breath of the other, and with a rush of courage, Jungeun closes the gap to press her lips against Jiwoo’s.

    It is as if someone set off fireworks. The pounding of Jungeun’s heart mirrors that of the explosions in the sky, the sensations and chills across her skin akin to the colours of the fireworks exploding across the canvas that the night provides. Jungeun feels like she’s floating with Jiwoo’s lips on hers, and Jiwoo’s thumb never stops drawing circles on her cheek. Jiwoo’s lips are so soft, and the tenderness of this first kiss surprises her. She’s always read about this moment in romance novels, but to experience the magical moment herself with Jiwoo is a whole other world to her. Jiwoo’s lips feel so right against hers, so, so right, and Jungeun can’t help but pull her closer, kiss her deeper.

    (It feels like happily ever after.)

    Jiwoo and Jungeun break the kiss, both girls panting heavily. Jungeun is still tense—disbelief floods her system that she’s just kissed her best friend, and she feels so complete, so overjoyed. What is this feeling?

    “Jungeun-ie, was that okay?” Jiwoo pushes a curl of Jungeun’s hair behind her ear. Jungeun nods, not trusting herself to speak right now. Her best friend looks so beautiful, so kissable, and she’s hungry for more.

    Jungeun leans in slowly, and Jiwoo meets her in the middle for another soft kiss. Jiwoo takes it up a notch this time—she nibbles Jungeun’s bottom lip during the kiss, sending tingles across Jungeun’s skin. Jiwoo reaches a hand behind Jungeun’s head, and she pulls Jungeun in deeper. Jiwoo breaks the kiss for a breath of air, and she returns to reconnect herself to Jungeun for another kiss. This time, Jiwoo is impatient—she has her lips slightly parted and her tongue swipes at Jungeun’s lips, seeking access.

    “Mmph?!”

    “Ah!” Jiwoo pulls herself back, apologies firing out of her mouth as she blushes red. Jungeun has never seen her friend so flustered before, and she takes the chance to hold her best friend’s hand as she’s always done when Jiwoo needed to calm down. Jungeun squeezes Jiwoo’s hand softly, and Jiwoo slowly relaxes, but her eyes never leave Jungeun’s. The thrill of doing this sinful activity with the other feels so intoxicating.

    “Sorry, Jungeun-ah. I got carried away…”

    “No, it’s okay.” Jungeun shakes her head. She trusts Jiwoo with her life. She knows Jiwoo wouldn’t take advantage of her.

    “I’m going to get into a more comfortable position, okay?”

    “Okay.”

    To Jungeun’s shock, Jiwoo crosses a leg over hers, pivoting on her left knee. She straddles Jungeun, kneeling over her hard bulge, but not touching. Jungeun can feel Jiwoo’s warmth radiating off her body, and she instinctively raises her hands to grab Jiwoo’s hips. Jiwoo just grins at the sight. Maybe Jungeun isn’t entirely innocent.

    “I’m going to kiss you again Jungeun-ie, but this time, I’m going to use my tongue, okay? Let’s take it slow.”

    Jiwoo leans in again. Her eyes flick to Jungeun’s lips before she closes them and their lips meet again. Both girls enjoy the kiss for a moment before Jiwoo breaks the kiss for air, then returns to swipe her tongue against Jungeun’s lips once more. This time, Jungeun opens her mouth slightly, and Jiwoo snakes her tongue into Jungeun’s mouth. Jungeun moans when Jiwoo’s hands, which are resting on her back, begin to rub up and down. Jungeun’s tongue rises to meet Jiwoo’s, both girls exploring how kissing the other so intimately could feel so good, so right, so wonderful.

    A string of saliva bridges the gap between Jungeun and Jiwoo when they break the kiss. Both girls gaze at each other lustfully—Jungeun’s cock strains hard against her pants, and Jiwoo is damned sure her panties are ruined beyond belief. Both girls desperately want to jump the other, but Jiwoo holds herself back—Jungeun is inexperienced, and Jiwoo does not want to come on to her so strongly from the get go, regardless of how much she’s wanted to fuck Jungeun for a while now.

    Jungeun stares deep into Jiwoo’s eyes. Her best friend’s eyes contain barely controlled lust, but underneath that, there is a certain fondness to her look. Jungeun doesn’t know what exactly to make of it. Is it just the friendship speaking? Or is there more than friendly feelings involved in this stare? Jungeun studies Jiwoo’s facial features carefully, admiring the simple beauty her best friend posesses. God, she really looks divine.

    “Jungeun-ah.”

    “Mm.”

    Jiwoo wraps her hand around Jungeun’s wrist. She pulls Jungeun’s hand and lays it on her chest, Jungeun’s palm fitting perfectly on her petite breast.

    “Go on, touch me.”

    Jungeun visibly gulps. Jiwoo kisses her forehead, and she guides Jungeun to touch her the way she likes. Her palm slides over the back of Jungeun’s hand, and she pushes at her best friend’s fingers to knead the soft flesh.

    “Ah~”

    A small burst of precum leaks from Jungeun’s cock at the sultry moan Jiwoo releases under her touch. Jiwoo’s breasts feel so good to touch and knead, and even with her bra in the way, Jungeun can’t get enough of it. Hell, Jungeun can’t get enough of her best friend. In a split second, Jungeun’s lips are against Jiwoo’s, and both girls share another deep kiss, their tongues gently swirling around the other’s. Jungeun swears she’s about to go crazy—kissing and touching Jiwoo this way drives her crazy.

    “Mmph!”

    With a flash of strength and basic instinct, Jungeun grabs Jiwoo by her waist and flips her over. Now, Jiwoo has her legs around Jungeun’s hips, and Jungeun in on all fours on top of her best friend, her hair falling to form a makeshift curtain around her and Jiwoo.

    “Ah! I’m sorry, Jiwoo-ah!”

    “Don’t be.” Jiwoo raises a hand to arrange Jungeun’s hair into a somewhat neat position. “You must really want me.”

    Jungeun doesn’t know how to respond.

    “Tell me, Jungeun. What do you wanna do from here?”

    Jungeun blushes all the way to the tips of her ears. She wants to see Jiwoo, all of her, but she… she can’t say it. She can’t bring herself to say it.

    “Mmgh…”

    Jiwoo only smiles patiently. She caresses her best friend’s cheek and lets her best friend work it out for herself. Jungeun can take all the time in the world if that’s what she needs. Jiwoo can wait.

    “I… I want…”

    “Yeah?” Jiwoo gives her a reassuring smile. God, her best friend is so damned adorable. Jiwoo just wants to kiss her silly and tell her how beautiful she is, how good she’s doing right now.

    “I want to see you.”

    “You’re looking at me right now, Jungeun-ie.”

    Jungeun sighs, her shyness enveloping her. Jiwoo just wants to tease her—her best friend giggles beneath her, acting all coy and cute.

    “I… I want to see you. All of you. Naked.”

    Jungeun stares away from Jiwoo as she admits her current desire. She knows Jiwoo wouldn’t laugh at her, but she sounds like such a pathetic virgin loser. She can’t just say it to her best friend like that!

    “Then help me out of these clothes, Jungeun-ie. I want to show you how I look naked too.”

    Jungeun scrambles to help Jiwoo up. Her hands pull at Jiwoo’s shirt clumsily, and Jiwoo laughs. Jungeun is adorable. So adorable. And so eager.

    “Chill, Jungeun, chill.”

    Jiwoo grabs Jungeun’s hands, and together, both girls tug Jiwoo’s shirt off her body. Jungeun throws it to the side, and her hands fall limply to her sides, her eyes boggling at the sight of Jiwoo clad in a cute maroon bralette. Jungeun’s heart pounds in her chest, and she’s hyper-aware of how sweaty her palms are. Sweat also drips down her neck, and she looks away from Jiwoo. She doesn’t wanna stare too much, even if Jiwoo said she was willing to show her everything.

    “You can look, Jungeun.”

    Jiwoo’s hands reach over to Jungeun’s cheeks. She twists Jungeun’s head to face her, then she reaches for her discarded shirt. With soft swipes, she wipes at Jungeun’s sweaty forehead and neck.

    “You don’t have to be nervous, Jungeun. It’s just you and me. You can look as much as you want, dear.”

    Jiwoo leans towards Jungeun’s ear, intent on teasing her a bit more.

    “Besides, I’m taking everything off for you anyway.”

    Jiwoo smirks at Jungeun’s audible gulp. She knows her best friend is almost at her limit with teasing—any more and she might shut down for the night. Jiwoo pulls at her best friend’s wrists, and Jungeun’s shy gaze meeting hers is the cutest expression she’s ever seen worn on the other girl. Jiwoo is unable to resist leaning in to peck the other girl on the lips.

    “Jungeun-ie, let’s carry on.”

    Jiwoo tugs at Jungeun’s hands again. She guides her best friend to the front clasp of her bralette, and she nods at Jungeun. Jungeun’s fingers slowly work on the clasp, and when it pops open, Jungeun slides the straps off Jiwoo’s shoulders, and Jiwoo pulls it off her, the garment thrown aside immediately after. Jungeun finally gets her first view of another girl’s bare chest.

    Jiwoo is gorgeous, Jungeun thinks. Her breasts are perky, petite in size, but they look perfect. Jiwoo looks perfect, is perfect. Jungeun can’t believe how lucky she is to be able to look at Jiwoo like that. Her eyes roam the expanse of honey brown skin exposed to her, but her lust multiplies hundredfold at the sight of Jiwoo’s pink nipples, hard with arousal. Jiwoo would probably be the death of Jungeun.

    Jungeun lunges forward, her lips crashing into Jiwoo’s. Both girls topple over, Jiwoo moaning softly at how aggressively Jungeun kisses her. Both girls share a sloppy openmouthed kiss, their tongues swirling around the other’s in an erotic dance. At the same time, Jungeun cups Jiwoo’s left breast, her palms gently kneading and exploring the sensations she gets.

    “Mmmh~!”

    Jungeun nearly goes mad. Jiwoo’s moan was so fucking sexy. Jungeun kisses her harder, kneads her breast with a little more strength. She wants to hear it again, has to hear it again.

    The need for air causes Jungeun to break the kiss. She stares at Jiwoo, breathless and flushed from the heightened arousal. Jungeun reaches for Jiwoo’s shorts, unwilling to wait longer to see the rest of Jiwoo’s body.

    “Jungeun-ie, stop.”

    Jiwoo sits up. She reaches past Jungeun’s frozen hands for her shirt.

    “It’s only fair for me to want to see you naked too.”

    Jiwoo pushes Jungeun’s shirt up. Jungeun helps to tug the shirt off her body, and Jungeun instinctively reaches for the clasp at the back of her bra. In a moment, Jungeun joins Jiwoo in being topless. Jiwoo’s eyes rake over Jungeun’s body, and she frowns when Jungeun covers her chest with her arms.

    “Jungeun-ie.”

    “Okay, okay.” Jungeun takes a deep breath, as if to psyche herself up. She slides her arms open and lets them fall to her lap. This time, Jiwoo can’t believe how incredibly beautiful her best friend is. Jungeun’s looks so damned hot—small brown nipples atop her cute breasts, her collarbones looking so good to mark. Jungeun looks so shyly, yet so hopefully at Jiwoo, as if expecting a compliment yet lacking some confidence in herself. Jiwoo can’t have that with Jungeun.

    “Jungeun-ah, you’re so beautiful.”

    The way Jungeun perks up warms Jiwoo’s heart. Her best friend’s lips curl up into a smile, but she’s still shy.

    “I’m so happy I’m the first to see you like that.”

    Jungeun leans in when Jiwoo does. Both girls share another kiss with each other, this one slow and sensual. When Jungeun pulls back, Jiwoo chases after her, hell-bent on reconnecting their lips for an extended kiss. Throughout their liplock, Jiwoo masterfully maneuvers Jungeun to lie on the mattress before she straddles her. Both girls stare into the other’s eyes when they draw away from the other, and Jiwoo smiles.

    “Are you enjoying it, Jungeun-ie?”

    “Yes.” Jungeun answers almost immediately. Jiwoo has been nothing but lovely, and Jungeun can’t believe how much she’s enjoying making out with Jiwoo. She wants to bask in the moment, this private moment between the two of them.

    She wishes it would never end.

    Jiwoo nods, and she leans in again. Instead of going for Jungeun’s lips, she kisses Jungeun’s chin, then she plants a line of kisses down to Jungeun’s neck. Jungeun whimpers under Jiwoo’s soft touch, gasps and moans escaping her lips with every kiss Jiwoo lands on her skin.

    “Oh, f-fuck!”

    Jungeun can’t help but swear when Jiwoo licks from her collarbone all the way to below her ear before she nibbles on her earlobe. Jiwoo also rubs circles on Jungeun’s left shoulder with her thumb. Jungeun tries to bite her lip to muffle her louder moans, but Jiwoo will have none of it.

    “No, Jungeun-ie. Let it all out for me, okay?”

    Jungeun nods, and she releases a broken moan when Jiwoo wraps her lips on a spot at the base of Jungeun’s neck, and she begins to mark Jungeun with a love bite. Jumgeun grips hard on Jiwoo’s upper arms, her nails digging harder into her best friend’s skin with every lewd sound Jiwoo makes. Jiwoo’s kisses only make Jungeun’s cock harder and wetter, her shorts now painfully tight. Waves of pleasure wash over Jungeun’s body, as if someone was passing an electrical current through Jungeun as a conduit.

    Jungeun feels lightheaded. Jiwoo’s on her third love bite, and Jungeun’s dizzy with how much pleasure she feels under Jiwoo’s touch like that. When she raises her head to look at Jiwoo, her best friend rises from her fresh mark on Jungeun’s collarbone, and she reconnects their lips in another torrid kiss, leaning her body flush against Jungeun’s. Jiwoo moans into the kiss when she feels Jungeun’s hard nipples graze her skin, her own against Jungeun’s, and when she breaks this kiss, she moves down to Jungeun’s breasts.

    “You’re so beautiful, Jungeun-ie, you know that? I just wanna kiss you, mark you, suck on your tits, fuck…”

    Jiwoo doesn’t wait for Jungeun’s answer. Her lips wrap around the taut bud on Jungeun’s right breast to apply a gentle suction. Her hand covers Jungeun’s other breast to apply the same gentle kneads and squeezes that Jungeun gave her earlier. Jungeun’s moans grow louder, her cock twitching with every swipe of Jiwoo’s tongue on her nipple, every soft caress of her breast.

    “Jiwoo, fuck, fuck, Kim Jiwoo~!”

    “That’s it, Jungeun-ie, let it all out for me. Fuck, you sound so good…”

    Jiwoo peppers kisses all over Jungeun’s breasts, her collarbones, and her neck again. Jungeun wants nothing but to have the main course right now—to finally have sex with Jiwoo—but she would be lying if she said she didn’t enjoy this with Jiwoo. She felt so loved, so taken care of, even if it was just a lesson. This wasn’t even sex, and she already feels so damned good. What about the actual sex?

    “Jungeun-ah, remember this well, okay?” Jiwoo giggles. “I love it when girls suck my tits the same way I sucked yours.”

    Jiwoo starts to trail kisses downwards, first under Jungeun’s breasts, then over her tummy. Jungeun can’t help but anticipate yet dread the moment Jiwoo reaches her cock. She’s never shown anyone else her cock—Jiwoo’s seen it about a decade ago, when they were both young children—but now, Jungeun’s matured a lot. After puberty, Jungeun’s cock is what most would call big, and while most would want that, Jungeun is somewhat insecure about it. She wonders if it’s natural to be a little bigger, and being shy about it doesn’t help much either.

    Jungeun draws a nervous breath when Jiwoo kisses her just above the waistband of her shorts. When Jiwoo looks up for consent, Jungeun nods, and Jiwoo gently shifts Jungeun’s shorts off her hips and off her toned legs. The huge tent of Jungeun’s boxers makes Jiwoo’s jaw drop and mouth dry up—no way her best friend was this massive. How could she have never known?

    “Jungeun-ie, can I take these off too?”

    “O-Okay.”

    Jungeun stares intently at her best friend while she slides the boxers off. Jiwoo deliberately averts her gaze to Jungeun’s erection standing tall and proud, the tip an angry red-purple, white precum coating the entire tip. When Jiwoo flings the boxers away, she finally takes her first look, and she licks her lips, almost unable to tear her eyes away. A shudder runs across Jiwoo’s body as she anticipates Jungeun’s massive cock stretching her tight little pussy. If it wasn’t Jungeun’s first time, Jiwoo knows she’d have mounted her cock and been halfway to orgasm already.

    “Jungeun-ah, you’re so big…”

    Jungeun nervously chews on her bottom lip. Jiwoo’s reaction doesn’t tell her anything at all, and she’d hate it if Jiwoo thinks she’s a monster.

    “If this wasn’t your first time, Jungeun-ie, I’d be fucking myself so hard on your cock right now.”

    Jungeun moans, her cock twitching hard while a spurt of precum shoots out of her tip. She whimpers when she watches Jiwoo pull her shorts and panties off together, her best friend finally naked in front of her. Jiwoo is clean shaven, her slick dripping off her pussy down her thighs. However, Jungeun is drawn to how hot Jiwoo’s figure is—she’s wanted to see this girl naked for so long, and her body didn’t disappoint at all.

    “Am I pretty, Jungeun-ie?”

    Jungeun nods rapidly. Jiwoo’s already gorgeous when clothed, and now that she’s naked, Jungeun can’t deny that she’s way too attracted physically.

    “That’s good.”

    Jiwoo crawls onto the bed, and she pulls Jungeun to sit up. She smiles at her best friend, her lustful gaze roaming across the other girl’s body, then to Jungeun’s eyes.

    “Look at you, so big and hard for me, Jungeun-ie.” Jiwoo crawls between Jungeun’s legs, resting on all fours with her ass up in the air. “Your balls are so full too.” She gazes up at her best friend, lips curling up when she hears Jungeun whimper. “I’ll teach you how good it feels to get your cock sucked next time, Jungeun-ie. I need to have this in my pussy right now, so I can finally teach you how good it feels to have sex.”

    Jiwoo moves to lie next to Jungeun, on her back. She directs Jungeun to kneel in front of her closed legs, her knees shielding most of her body from sight. The older of the two stares at her best friend as she spreads her legs open. Jiwoo glistens under the shine of Jungeun’s LED lights, every little detail bared all for Jungeun to see. Jiwoo’s outie pussy parts open slightly, her juices dripping from deep within, skin coated with a sheen of slick. A hard nub protrudes at the top of Jiwoo’s pussy, and Jungeun gulps—Jiwoo must be super turned on for her clit to be out like this.

    “Jungeun-ie, you’re staring.”

    Jiwoo has a teasing grin on her face. She knows she has Jungeun’s attention entirely, and she wouldn’t pass up a chance to be the lewdest with her cute best friend. In fact, Jungeun’s so horny and attracted to her naked body that she’s not even bothering to hide it—she’s flushed so red, pupils dilated, and her cock’s so damned hard… Jiwoo just wants Jungeun to put that cock deep into her pussy, stretch her walls out and fuck her like the horny slut she is for her best friend. Jiwoo pulls her labia open with both hands, a coy smile on her features.

    “Jungeun-ah, come learn how good it feels to have sex with me.”

    Jungeun crawls up closer to Jiwoo, unable to tear her eyes off Jiwoo’s pussy. Jiwoo lifts Jungeun’s head with a finger under her chin, and when Jungeun looks at her, she leans in to brush her lips against Jungeun’s in a chaste kiss, before she says the hottest words Jungeun’s ever heard.

    “Next time I’ll show you how good it feels when I suck your cock, Jungeun-ie. I’ll even teach you how to eat me out, but now” —Jiwoo grabs Jungeun’s hard length and lines it up with her dripping hole, all while stroking her gently— “I’m going to teach you how good sex feels.”

    Jungeun feels like lightning just struck her. Jiwoo wants to have sex with her again? There’s going to be a next time? The thought of seeing Jiwoo naked again, with her beautiful lips wrapped around her hard cock makes Jungeun pulse. At the same time, Jungeun has a mini-orgasm—her cock jerks hard as a shot of hot cum fires out of the tip onto Jiwoo’s pussy, the white gooey liquid running down Jiwoo’s skin.

    “Oh, you really liked that, didn’t you, Jungeun-ie?”

    Jiwoo’s lust burns even brighter seeing the mess on her pussy. She grins when her fingers come into contact with Jungeun’s cum, the strands sticking onto her fingers and coating them in a glossy sheen. Jiwoo raises her fingers to her mouth and drips the cum onto her tongue, then she sucks on her fingers one by one, all while staring at Jungeun.

    “You taste so nice, Jungeun-ah.”

    Jungeun whimpers.

    “Next time I’ll taste it right from the source. For now…”

    Jiwoo slides Jungeun’s messy tip across her labia, her slick mixing with the precum all over her best friend’s cock. Jungeun is super warm, and Jiwoo can’t believe how hard and big it is in her hand. Even with a hand fully grabbing the length, Jungeun still sticks out from the other side. Jiwoo knows how much of a stretch it’ll be—Jungeun’s about the size of the largest dildo she owns—but she’s ready for it. Jiwoo needs it in her pussy, fucking her hole until Jungeun fills her with cum.

    “Jungeun-ie, put it in when you’re ready.”

    Jiwoo pushes herself against Jungeun’s cock, the tip resting right at the entrance to her pussy. Just one push and Jungeun’s tip would sink into her hole, and maybe Jungeun would push in all the way, filling her needy pussy full of her cock. Jiwoo wants Jungeun to fill her entirely, and then she’ll teach Jungeun how good it feels to finally have sex.

    “Anytime, Jungeun-ie.”

    Jungeun hesitates. She wants to, she needs to, but when she stares at Jiwoo’s inviting and patient smile, a rush of fondness fills her. Gratitude and adoration spreads through Jungeun, and the need to let Jiwoo know follows after. She grabs Jiwoo’s arm and tugs at it, Jiwoo sitting up.

    “Is something wrong, Jungeun? Are you okay?”

    The concern written on Jiwoo’s face makes Jungeun feel so loved. In their fifteen-year friendship, Jungeun’s felt loved many times, but it was never this intimate. Jiwoo has her hands placed on Jungeun’s shoulders, the warm touch sending waves of comfort over her body. Never before has Jungeun felt like Jiwoo was home as much as she does now, and she can’t help but realise how much she does truly love her best friend, but she’s still a little unsure about it—is it love love, or is this just ultra-best friendship?

    “Yeah. Yeah, I’m okay, I’m okay.”

    Jungeun draws her lips to Jiwoo’s, and they engage in a soft sensual kiss once again. Both girls’ tongues meet in the middle, and Jungeun gently lowers Jiwoo onto the mattress, soft moans escaping from their liplock. Jungeun feels so good kissing Jiwoo, and if she wasn’t about to finally sleep with her, she’d spend an eternity kissing her best friend. Jungeun reluctantly separates herself from Jiwoo, but she smiles when Jiwoo caresses her cheek, her grin mirroring Jungeun’s own.

    “Like I said, anytime you’re ready, Jungeun-ie.”

    “Okay.”

    Jungeun grips herself by the base and takes a deep breath. She gives Jiwoo one last look, and Jiwoo nods and smiles. With a soft thrust, Jungeun parts Jiwoo’s walls with her hard cock, and both girls moan loudly with every inch of Jungeun that enters Jiwoo. Jiwoo is fucking tight, so damned deliciously tight, and so wet. Jungeun slides in with just a little resistance, and both girls fall onto the bed at the pleasure coursing through their veins. Jiwoo grabs onto the bed sheets as an outlet for the intense pleasure of Jungeun stretching her out while Jungeun pants heavily with every bit of her cock that she pushes into her best friend. When she finally hilts into Jiwoo, she falls onto her best friend’s chest, and Jiwoo cradles her in her bosom, both girls attempting to catch their breaths. Fuck, Jungeun feels like blowing her load already—she’s dangerously close—and she really needs the break.

    “Congratulations, Jungeun-ie. You’re not a virgin anymore.”

    Jiwoo strokes Jungeun’s hair softly, laying soft pecks on her head wherever she can. She wants Jungeun to move, to make her feel the stretch of her huge cock even more, but she waits for Jungeun. She knows how intense first times can be, and she’d hate herself if she rushed her best friend selfishly for her own pleasure. She wants Jungeun to know how much she’s loved and cared for, and how much Jiwoo wants to please her too.

    “Thank you.”

    Jungeun’s soft voice echoes from the mess of hair on her chest, and then Jungeun looks up, her head lifting off Jiwoo’s chest. Jungeun moans when she shifts a little for more comfort, and Jiwoo bites her lip at the feeling of Jungeun against her walls. Fuck, Jungeun feels so good inside her, the stretch so fucking good…

    “You can move, Jungeun-ie.”

    Both girls moan when Jungeun slides herself outwards, then thrusts back in. Her strokes are slow and methodical at first, but then she speeds up without warning. Jiwoo yelps at a hard thrust, then the sudden loss of contact altogether when Jungeun slips out of her in her eagerness to fuck Jiwoo. Jungeun is horrified.

    “Ah!”

    “Oh, shit, sorry!”

    Jungeun aims for Jiwoo’s hole again, and she slides herself in. Before she can thrust again, Jiwoo grabs her arm and pulls her in for a short kiss, then she begins to direct her.

    “Jungeun-ah, keep your thrusts slow and steady first. No need to rush it. Be consistent with your thrusts and you’ll feel so damned good, okay?”

    Jungeun nods, a little ashamed at her overeagerness. She worries about how Jiwoo sees her now, for she might’ve just fucked it up.

    “Hey, Jungeun-ah. It’s okay.” Jiwoo sits up for a kiss on her forehead. “It’s your first time. I was super eager for my first too, and I had to be calmed down the same way. It’s okay, it’s normal. Let’s try again together, okay?”

    Jungeun’s response is to kiss Jiwoo desperately. She pushes Jiwoo back down, her hips beginning to move slowly just as Jiwoo said. This time, Jungeun pulls about half of her shaft out and then thrusts back in, repeating the motions slowly and methodically. Jiwoo breaks the kiss to moan out loud again, her breath hitching every time Jungeun hilts.

    “You’re, ahh, so fucking… big, Jungeun-ie!”

    Jungeun’s about to lose her mind. Jiwoo’s pussy feels like heaven, and her moans the angelic choir. If this is how good sex feels, Jungeun fears she might get addicted. The warmth, the tight grip, the slick wetness, and the pleasure, oh, the pleasure, so delicious, so euphoric, so right.

    “So… fucking… tight!”

    Jiwoo’s walls clench around Jungeun’s cock on a particularly hard thrust. Jiwoo squeaks in pleasure and turns her head to the side, her body writhing in the enjoyment of Jungeun’s cock spearing into her tight hole. Jungeun stares at Jiwoo’s exposed neck and she darts for it, her tongue licking the same stripe Jiwoo left on her, but she instead nibbles at Jiwoo’s earlobe at the end. Jiwoo’s airy moans makes Jungeun grin, and she trails a line of kisses down her best friend’s neck, then she works on leaving a mark of her own. Fuck, Jungeun can’t get enough of Jiwoo, she needs to claim her, mark her, love her.

    “Jungeun-ah, fuck, Kim Jungeun!”

    Jiwoo’s sharp whines of Jungeun’s name prompt her to thrust harder. Earlier, Jungeun only pulled out half her shaft, but now she settles for three-quarters instead. Jiwoo’s broken moans on every hard thrust drives Jungeun crazy—her best friend sounds so good being fucked like that, and her body feels so amazing, so perfect around Jungeun’s hard cock. Jiwoo’s walls clench hard around Jungeun with every thrust, her body arching into Jungeun’s, hands grabbing whatever she can, hungry to feel her best friend’s skin against her own, for her best friend to embrace her as they make love.

    “Jiwoo-ah, am I doing well?"

    "Oh, fuck, fuck, you’re doing so good, fuck, you’re my good girl, Jungeun-ie, you’re doing so well, I love it, you’re fucking me so good!”

    All Jungeun can hear is Jiwoo calling her a good girl, her good girl. Yes, she’s Jiwoo’s good girl, she’s Jiwoo’s best girl, she wants to be Jiwoo’s only girl.

    “Oh, FUCK, FUCK, JUNGEUN-IE, FUCK, KIM JUNGEUN!”

    Jungeun now snaps her hips on every thrust, her cock almost all the way out every time, leaving only the tip in Jiwoo’s cunt before she buries herself back into the tight embrace that her pussy offers. Jiwoo’s body rocks with every thrust, and she tries to push herself down against Jungeun every time the older girl hilts. Jiwoo needs Jungeun to fuck her harder and deeper, for Jungeun to explore as much of her body as she can. She wants to let Jungeun know that she’s hers, that she wants Jungeun to claim her. That’s the reason why she’s letting Jungeun sleep with her, because her and Jungeun are definitely the endgame. She loves Jungeun, and she knows Jungeun definitely loves her, even if she’s a little slow about it. Soon, she thinks, soon Jungeun will realise it.

    “FUCK, YES, JUNGEUN, YES!”

    Jungeun fucks Jiwoo hard, desperate for praise and for pleasure. She wants to give herself to Jiwoo, to let Jiwoo take her. Her lips crash into Jiwoo’s, both girls moaning into their shared sloppy kiss, tongues duelling each other in their expression of love, the culmination of their feelings. Jungeun ignores how sore her abs are—how much core strength was needed to thrust into Jiwoo the way she does right now? Whatever, Jungeun doesn’t need to know right now, not when her best friend is under her, sharing the pleasure of the most intimate acts.

    “Fuck, Kim Jiwoo, Kim Jiwoo, fuck, fuck, Jiwoo!”

    Both girls chant the other’s name like a mantra. Jiwoo attempts to fuck herself up against Jungeun on every upstroke, hell-bent on having Jungeun’s thick cock fuck deeper and deeper into her each time. With how hard Jungeun fucks her, the older girl’s balls slap against Jiwoo’s skin every time, cock hitting Jiwoo’s G-spot every stroke.

    “Fuck, Jungeun-ie, you’re my good girl, my good, good girl, you’re my best girl, fuck, you’re doing so well for me, you’re my favourite girl, my best girl…”

    “Jiwoo, Jiwoo, Jiwoo, JIWOO~!”

    Jungeun releases a broken moan, and her hips stutter. Jiwoo gasps loudly in surprise as she feels Jungeun’s cock throb hard in her walls, and then her moans cut out when her orgasm hits just as she feels Jungeun’s thick, warm cum flood her walls. Thick spurt after thick spurt of Jungeun’s semen shoots deep into Jiwoo’s womb, and Jiwoo can’t contain the satisfaction that washes over her—she’s wanted to feel Jungeun’s cum fill her tight pussy for years, and she’s always fantasized about it over many late nights. As for Jungeun, her hips never stop moving throughout her orgasm, through Jiwoo’s orgasm, even as Jiwoo’s body goes rigid beneath her, then her hips buck repeatedly, pussy crushing Jungeun’s hard cock over and over as her walls quiver. Rushes of wetness wash over Jungeun’s thrusting cock, every spurt of her cum fucked deeper and deeper into Jiwoo’s body. Jungeun can’t help but moan Jiwoo’s name over and over as she cums, arms wrapped tightly around her best friend’s body. She wants Jiwoo to know how much she enjoyed this, enjoyed being with her, enjoyed it because of her. She doesn’t know what she exactly feels, but she knows that Jiwoo is happiness, and that’s enough.

    Jungeun pulls out of Jiwoo slowly, a wet dirty “Plop!” sound sent into both girls’ ears before a deluge of cum flows out of Jiwoo’s freshly fucked cunt. Strands of Jiwoo’s cum still stick to Jungeun’s cock, and Jungeun bites her lip at the sight—even after sex, Jiwoo still looked so sexy, so beautiful. The afterglow of their session shines off her, and Jiwoo’s radiant beauty is something she’ll never tire of.

    “Jungeun-ah, you naughty girl… you came so much…”

    Jungeun’s heart stops. Oh, fuck, she came into Jiwoo. She orgasmed in Jiwoo’s pussy. Fuck, she wasn’t ready to be a mother, as much as Jiwoo would be someone ideal to take care of a child with. She couldn’t!

    “Ahahahaha! Jungeun-ah! You should’ve seen the look on your face—HAHAHA!”

    Jiwoo giggles atop the mattress before she sits up. More of Jungeun’s cum leaks out of her, but she doesn’t care about how it stains her skin—she crawls up to Jungeun at the foot of the bed, and she kneels to be at the same height as her best friend.

    “It’s okay, Jungeun-ah. I’m safe today. I wouldn’t have let you do it raw if I wasn’t safe.”

    Jungeun heaves a sigh of relief, and she blushes when Jiwoo’s soft lips land on her cheek. She clasps her hands together and looks to the floor, her shyness returning. She can’t believe it—she finally knows how good sex feels, and damn it, she just slept with Kim Jiwoo and loved every second of it.

    “Was it good, Jungeun-ie?”

    “Mm!” Jungeun nods, and Jiwoo laughs before she bounces forward to wrap Jungeun in a tight hug. Jungeun returns the embrace, and the moment is broken when Jiwoo whispers another set of incredibly arousing words into her ears.

    “Jungeun-ah, out of all the people I’ve slept with, you’re the first and only one I’ve let cum in my pussy. Congratulations on being my first.”

    Jungeun chokes, and Jiwoo grins. She soothes her best friend with warm strokes down her back, and the shit-eating grin she wears gets Jungeun to reluctantly smile too. Jungeun thinks that there cannot be anything prettier than Kim Jiwoo smiling. Ever.

    “Come on, Jungeun-ie. Let’s shower!”
