"Hey baby, Arin needs some help from you, do you think you could help her?"

"Sure, what does she need help with?"

"She wouldn't say, and she shares everything with us, so maybe it is guy-related? You'll have to ask her when you see her."

"Alright, where and when does she want to see me?"

"Saturday afternoon should work, we don't have anything then, I'll text you her address."

"Okay, we still good for dinner tonight?"

"Yes! See you then, love you!"

"Me too, bye!" You end the call with Binnie and go about your day. You meet her for dinner and walk her back to her apartment, Arin doesn't come up at all, so you don't think much of it at all as you go through the week.

Saturday comes around and you find yourself at what turns out to be Arin's apartment, you knock on the door and Arin lets you in, giving you a nervous but cheery greeting. She's dressed simply in a plain white t-shirt and jean shorts, looking innocent and fresh as white snow. You always thought of her as Binnie's younger sister, but she's stunning in her own right.

"Hi oppa, thank you for coming! I really need help, and Binnie unnie raves about you all the time, so I thought you would be perfect."

"Sure, not sure what I can help with since she didn't tell me anything, but I'll do whatever I can to help."

"I didn't tell her either, I'm too embarrassed to tell the members, they'll laugh at me." She fidgets, blushing a little at what seems to be a sensitive topic.

"Why don't we sit down and tell me about it?" You follow her into her living room and plop yourself down on the couch as Arin hurries around the house, trying to be a perfect host, but really just trying to delay talking about it.

"Do you want some snacks, I have some chips, I can go grab them, or ice cream? Or-" You grab her arm and have her sit with you, trying to get to the main topic.

"Arin, I'm fine, water is enough. Why don't you tell me what's going on?" You see her bite her lower lip, her cheeks turning red as she tries to broach the topic with you.

"So you know how the unnies... we play with each other right?" She looks at you nervously.

"You mean... sex? Yeah Binnie and Jiho told me about it. Nothing wrong with that, it must be tough as idols." Arin nods furiously before continuing slowly.

"When we use... toys, I find that it feels good, I can get to, to..." Her voice dies away as she tries to find the right word for it.

"Orgasm? You can cum?" Arin sinks her head to her chest, her face bright red as she gives you the smallest of nods.

"That's good, so what's the problem?"

"But when I've tried it with guys, I can't... you know. I don't know if it's something wrong with me, or with the guy, or... I don’t know." The words come flooding out with a rush as Arin finally lays the problem bare for you, she pulls her knees to her chest, wrapping her arms around her legs and looking at you with wide eyes, as if scared about what you will say.

"How does it feel when they... put it in you?" You find yourself blushing as you try to help Arin with this awkward topic.

"It feels rough? There's pain, and I'm always freezing up and tense, and before I realize what happened they're done already. I end up feeling so sore and it hurts down there."

"Ouch, looks like the guys are rushing into things. Do you want me to... I don't know, make a list of things they should do that you can show them?"

"N-no... It hurt so much last time I'm scared to do it again, but Binnie unnie always looks so satisfied after she comes back from your place, so could you... do it with me?" The last words trail off to a whisper as Arin's head sinks further between her knees, almost trying to curl herself into a ball. Your mind goes blank as you try to process what she is asking.

"A-Arin, do you know what you are asking?"

"Mmhmm..."

"I need to ask Binnie, is that okay?"

"Yes."

You call Binnie, putting her on speakerphone.

"Hey Binnie, I'm with Arin right now. She wants me to show her like how I showed you when we first met, is that okay?"

"Oh is that it? She could've asked anytime, why so secretive? I told you oppa, you can show the other members a good time, but when I want you, you are mine alone!"

"I know I know, you're amazing you know that?"

"Of course I know that, you better not disappoint her!"

"Thank you unnie!" Arin calls out shyly over the phone.

"Have fun!" Binnie hangs up with a quick click.

"Thank you for not telling her about my... problem." Arin says softly.

"Of course, it's not your fault, it's the guys you've been with that are the problem."

"How should we begin?" Arin looks up at you innocently, and many possible images and scenes, each more carnal and lewd than the last, spring to mind - never have you thought about being in this position! But you shake your head, forcing yourself to focus on the task - today is to be about her, and showing her how good sex can be.

"We will do what you want to do, okay?"

"But I don't know-"

"When we get there, you will. I'll help you get there." You bring Arin into your lap with a hug. "First, we begin with foreplay - we kiss." You bring your face close to her, admiring her smooth skin and gorgeous features - her cheeks are red with embarrassment and nervousness, her eyes wide open, surprised at your sudden closeness. Her mouth is open a little, her rosy lips expecting a kiss. You tease her, getting close to her lips with yours, but not letting them touch, pulling back when she tilts her head forward a little, trying to capture your lips. You feel her hot breath on your face before you finally make contact, your lips finding hers.

She lets out a happy squeal as you pull her deeper into the kiss, your hand finding the back of her neck, gently tilting her head towards you. Your tongue probes her lips, and Arin willingly lets you in, her tongue capturing yours with a quick dart, trying to pull you into her. Arin tastes delightfully sweet as your tongues tangle, playing out what will happen with your bodies later on. Both of you find yourselves running out of breath, and with a gasp you separate, a string of drool the only remaining connection between your lips. Arin's face is flushed red like a rose in bloom as she looks at you with desire. Her chest rises up and down rapidly, taking deep breaths to gather herself.

"T-that, that was..."

"That was just part of foreplay, now, I kiss you." You lean forward, pushing Arin to the couch. She reaches her arms around your neck, as if to kiss you again, but you dodge her advances, your lips finding their way to her neck instead. Soft moans fill your ears as you feel Arin shudder against your face, the hairs on her neck standing up in sensitivity. She arches her head back, presenting you with more of her neck to line with kisses. Your lips make their way down to her neckline, nuzzling your face in her defined collarbone. Your hands drift across her slim body, running down her shoulders to her waist, finding the hem of her t-shirt before slipping under, leaving feathery touches on her taut stomach. Her body arches into yours with want, the space between your fingertips and palms quickly filled as Arin presses her flesh up into your hands. When you feel her lithe legs reach up towards you, trying to wrap themselves around you, you know she is ready for the next step. You somehow get yourself to pull back from kissing her neck and shoulders, admiring her beauty. Arin's eyes are filled with need, clearly aching for more of your touch.

"When she is ready, you take off her clothes-" Before you can follow up with a question, Arin has stripped herself of her t-shirt, the thin white top thrown on the floor somewhere. You put a hand out to stop her, but not before pausing to admire her perky breasts. "Wait, do you want to take it to the bedroom?" Arin responds instantly, getting off the couch and dragging you to her bedroom in record speed. She sits you on the bed before standing herself in front of you. Her hands are a blur, one going to her back and unhooking the simple white bra she had, while the other works the button on her shorts. In a flash Arin is standing in front of you, with not a single piece of clothing on except for her matching cotton white panties. Her nipples are stiff with arousal, pointing straight at the object of her desire.

"W-what now?"

You retake the lead from her, laying her down on the bed. "Now, I touch you. Where do you want to be touched?"

"Everywhere, my-my whole body feels so hot..." You follow her instructions, your hands not leaving a square inch of her skin untouched as they roam her body. Breathless whines and gasps fill the room as Arin gives voice to her most sensitive spots - the side of her neck, her nipples, her left hip, and her right thigh. The smell of her arousal fills your nose as her body behaves like putty in your hands, twisting and turning in pleasure, trying to have the feel of your touch on as much as of her as possible.

"P-please touch me d-down there..." The words come unbidden from her lips, her mind a haze of wanton desire. You look down her body, your eyes stopping and feasting on the sight of Arin's panties completely soaked through, her pink shaven pussy clearly outlined against the now useless fabric.

"Arin you are so wet..." Your voice your thoughts out loud for her to hear. Her unfocused eyes follow your hands as they find themselves on either side of her hips, fingers hooking the hem of her panties before you finally pull down and leave Arin naked as the day she was born. Her pussy is like a pink rose, her lips positively eager for your touch, dews of arousal pooling around and below her. A cry erupts from her as you run a finger down her slit, her hips bucking up at you, clearly eager for more.

"T-then, you prepare her..." You stutter your next step, your voice failing you, deadened by the layer of intimacy and desire in the room. You prepare two fingers, making to slowly penetrate the writhing woman under you. Until she stops you dead in your tracks, her knees coming up to catch your arm.

"No, no fingers."

"I want to prepare you, make sure you're ready."

"No, I know how fingers feel in me, I want your-" She gazes pointedly at the tent you are pitching in your pants.

"I don't want it to hurt for you again."

"Do you not see this?" Arin reaches down herself, splaying her own lips for your benefit, laying her needs bare in front of you. "I-I've never been so wet in my life, please, I can't wait much longer..." When Arin makes her request like that, there is no way you can refuse or resist. You quickly strip yourself down to nothing and hover over her, the two of you breathing heavily with mutual want. However, as much as she wants it, you feel her tense and freeze when you place your tip against her entrance, you look down at her bright red face, her eyes tightly shut, her expression one of confusion as her body almost actively fights against her own needs.

"Hey, hey, I'm here for you, okay? Relax, I won't hurt you, I'll be slow." Arin eyes open, as if remembering that you are here, and her expression softens. She gives you a slight nod, indicating that she is ready. Slowly you push yourself into her - she is very tight from nervousness, and you take it extremely slow, kissing her gently as you get her to relax and used to your size.

"You're doing a good job, I'll keep going slowly." You reassure her before delving more and more into her depths, stretching her out slowly rather than smashing your way in like her previous partners did. Arin looks almost adorable as she seems to be holding her breath, her eyes glued shut, before you finally bottom out in her. You tap her nose, "Hey, breathe, I'm... I'm all the way in you now." Arin lets herself relax, exhaling before looking up at you with a smile that promised so much more.

"I-I feel so full. It wasn't painful at all."

"It shouldn't, and you being so wet definitely helps."

"Can you move now? I want to feel you when I'm not holding my breath."

"Okay, I'll move just a little bit." Arin whimpers as you slowly pull out, extracting mixed squeaks of pleasure and pain from her. It takes all your willpower not to begin thrusting yourself in and out of her, her warmth almost all consuming, gripping you tightly, not wanting you to leave. After agonizingly pulling your hips back, you plunge back into her, still slowly, but much more firmly, staking your place in her body. Arin arcs her back against you, pushing her delectable chest in your face as she fully takes you once more. You plant kisses on her breasts while you hold you your position in her, trying to dissipate any discomfort she feels. When you pull out once more, Arin seems to deflate, her upper body relaxing and sinking into the bed. For countless minutes you repeat your motions, Arin tensing up and arcing off the bed every time you bury yourself in her, before relaxing and dropping back down when you pull out. Thankfully, you notice that Arin is tensing less and less with every entry into her, and you whisper words of encouragement for her.

"You're amazing, it feels so good in you, any guy would be lucky to be with you."

"Thanks oppa... it's starting to feel really good for me too." True to her words more of her vocalizations begin to leak out, her squeals and whimpers taking on a note of pleasure as you set a slow but steady pace, rocking your hips into her with consistency. You watch Arin's expression with satisfaction, her eyes shut, her arousal creeping up her cheeks once more, her mouth slightly open as she takes quick breaths, trying to keep up with the pleasure battering her senses. You zone out, all your attention on trying to last as long as possible in this delightful woman. This all grinds to a halt when you feel her legs press against you from behind, trapping you in place.

"What is it?"

Arin's eyes open, instantly finding yours. The two of you exchange unfocused gazes, the need and want reflecting and bouncing off each other. You can almost see the lust cloud her vision as you feel her legs push you further into her, and Arin makes her wishes known.

"Faster."

You are all too happy to oblige, and you stop pausing between thrusts, taking your place in Arin's body over and over again. Her sounds cross from whimpers to long and pleasure-filled moans, the tone downright sexy in your ears, egging you on to increase the pace as her walls grasp on to you with every velvety muscle, sad to feel you leave and eager to welcome you time and again. Her head tosses and turns left and right, trying to find some outlet for her pleasure, biting on the pillow under her head, groaning with gritted teeth. When her hands are not on your arms they are found behind her head, grabbing the pillows with a iron grip, threatening to tear the pillow to pieces.

"Oh oh! Hah it feels so good!" Arin's exclamations of joy light a fire under you, all her discomfort gone, replaced only with pure rapture. She pulls you down to her, kissing you deeply with need, voicing her pleasure to you in the most direct way she knows how. You embrace her, feeling her delicate body tremble and rock with every thrust you fill her with. She grips your arm tightly, breaking the kiss to shatter the last restraint you had.

"Harder!" You unleash your desire on the needy woman below you, changing your position to powerfully thrust into her. The thunderous clap of your hips against her thighs join Arin's piercing screams in filling the room, the sexual din ringing through the apartment, and probably the whole building. Her walls flutter against you, randomly contracting every time you find yourself in her. Her hands scramble across your back, scratching you lightly, and her legs trap you against her once more, keeping you stuck in her, not that you minded.

"Oh yes! I'm-" Arin's cry is interrupted by her body as she crumbles under you, announcing her climax with a shriek, her back arcing off the bed again, this time out of insane pleasure rather than nervousness. It takes all of your discipline to not join in her orgasm, feeling her heat clamp down on you, her slick tunnel massaging all along your shaft, trying to coax your seed out of you. You barely manage to resist, grunting and tensing your thighs, trying to ignore the pleasure threatening to overwhelm you. Arin slowly drifts down from her peak, her limbs falling off you, a sigh leaving her lips when her head finally clears the fog of pleasure. Her beautiful face covered with a sheen of sweat, strands of hair clinging to her flushed face.

"How was that? You look beautiful."

"T-thank you, it was amazing..." Arin looks down her body, feeling and noticing your still hard cock. "You didn't cum? Let me help you!" Before you can react you find yourself on your back, Arin getting off you with a wet plop. You barely have a moment to complain before you cock is enveloped by her warm mouth, causing you to moan out loud. Arin's skill is amazing, her tongue teasing the underside of your member before swirling around your tip. You lose control of yourself, throwing your head back and bucking your hips into her face.

"Holy... Arin how are you so good at this?"

"I have dildoes and I practice! The unnies taught me too, Binnie unnie told me what you like. Mmm I taste good!" From the feel of things Binnie definitely did - Arin's hand strokes the base of your cock while the other massages your balls, trying to get you to cum for her. Her mouth descends on you again, Arin going back for a second taste of herself. Slobbering all over you, the image of Arin practicing her blowjobs on a dildo appears in your imagination, and it doesn't take long for you to go over the edge. You tap her head, trying to let her know, but she completely ignores you, keeping herself attached to your member. Unable to hold back, you finally let go.

"Ugh, yes!" The discipline you showed earlier by not joining Arin in orgasm takes it's revenge on you, your nerves all the more sensitive to the pleasure Arin's blowjob gives you as you cum now. Her tongue laps at your head, prolonging your pleasure as you shoot streams of hot white liquid down her throat. It proves too much for her - with a cough Arin gets off you, your seed spilling from her mouth. The young woman is embarrassed by it, quickly wiping her lips.

"Sorry oppa, you came more than expected."

"That's because you turned me on so much, you did such a good job." Arin blushes at the praise, but soon she is back at it, her hand stroking your semi-hard erection. You groan out loud, her soft hand proving too stimulating for your overworked nerves.

"Arin? What are you doing?"

"I want to get it up again. Can I try being on top? The guys I did it with didn't want to do that." Your eyes widen at Arin's request, her eyes showing her need and desire to explore, as if a seal on her lust has been broken. The look on her face is seductive, gone is the image of the maknae being babied by Binnie and the others - the Arin in front of you knows what she wants to try, and she demands that you will help her. You are quickly back to full hardness thanks to Arin's work, stroking and licking up and down your shaft, getting you ready for her. She looks up at you for approval.

"O-of course, I told you, we'll do what you want."

"Okay, slowly..." Arin talks to herself, her breasts tickling your skin as she makes her way up your body. With a kiss she sits up on you, her knees straddling your hips. She grips you with one hand, guiding you to her entrance, her juices dripping on to your cock. You moan out loud at the ceiling, feeling yourself in her folds again once more as she begins. Slowly she lowers herself on to you, getting about half of you in her, until her attention slips. "So big... Aah!" She slides the rest of the way down, and a moan leaves your gritted teeth as Arin collapses on you, impaling herself on you fully.

"Are you okay?"

"Y-yes, it was feeling so good, and then I went down too fast and it felt so, so nice..." Your heaving chest matches hers as she places her hands on your chest, using you for balance. She bounces herself on you, trying to recreate the pleasure she felt. Arin's cries saturate the room, the young woman raking her nails on your chest as her sleeve slides over your cock again and again. The jiggle of Arin's perky breasts hypnotize you, and your hands gravitate to them, grabbing her chest like she has with yours, playing with her stiff nipples. The exercise proves tiring for her, however, and her bounces get slower and lower over time, sweat dripping from her forehead, her face red with both pleasure and exertion.

"Hey, you should try grinding, it's easier." You suggest, your hands going to her butt, grabbing her fleshy cheeks, pulling and pushing her back and forth on top of you. Arin whines at the new sensation, feeling her clit grind on your pelvis. When she gets the hang of it you let go of her, allowing Arin to discover what she likes. You sit back and enjoy the pleasure of Arin gyrating and grinding herself on you, exploring all the new sensations and finding out what feels best for her.

"Oh!" With a sob Arin finds something that she likes, and soon she is repeating that motion, making sure you hit her favorite spot she didn't know she had. You watch in awe and arousal as Arin twists herself into a pleasurable mess on top of you, her eyes open but unfocused, mouth hanging open, all her senses focusing on rubbing her clit on you and your cock on her g-spot. A flush spreads across her pale body, blood flowing hurriedly through her, matching the pace of her hips. Wordless moans escape her, rising in pitch as she rides you faster and faster, until finally she can ride you no longer.

"Oh oh, something's-" You briefly see the whites of her eyes before they shut, her face going slack with pleasure before she ceases to function. "Nnngh!" A primal groan you never thought to hear from Arin finds its way to your ears as she collapses on you. You feel a gush of fluid cover your crotch, Arin losing herself completely and squirting all over you, her mind temporarily but completely overwritten with pleasure. You wrap your arms around her, holding her quivering body tenderly against you, stroking her messy hair down her toned back, feeling the heaves of her body gasping for breath. She lies against you motionless for several minutes, and you worry about her until you feel her fingers grab your arm, the rest of her body slowly coming back to life.

"That was... intense, I’ve never came like that before." Arin gasps between breaths, lifting her body off you slightly and eyeing your glistening crotch and the large wet spot on her sheets. "Wow, why are we so wet?"

"You squirted, you came really hard."

"Oh no, I'm so sorry!"

"No, it's really hot, it means you really enjoyed yourself there." You kiss the blushing maknae. "That's never happened before?"

"N-no, it never feels that strong... or that wet when I do it with the unnies, the feeling was strange but really good." She nuzzles against your chest. "Thank you." The motion causes her to jerk against you, and your cock throbs in response, making you immediately aware of how close you are to climax.

"You should get off, I'll take care of it if you're tired." You try to push her off you, but Arin holds on, instead sitting herself up on you again.

"No, let me." Without a further word she starts riding you again, grinding herself against you like she did a few moments before. She rocks herself on you slowly, quiet, whispering moans leaving her lips, her sensitivity not allowing her to go any faster, but it is enough to bring you to the edge.

"Arin, you should get off, I'm so close." She doesn't listen, upping her pace a little, using the last of her strength to pleasure you.

"Arin, you need to stop, I can't last-" Arin seals your fate with a sweet kiss and a whisper filled with gratitude, her hair tickling your cheeks.

"Don't."

"Arin!" Her name fills the room, but your ears only hear her mewls of satisfaction as you drain yourself in her, giving yourself over to your orgasm completely. Your hands find their way to her butt, holding her down on you while your hips buck up into her, filling her up with your pent-up pleasure. You lose count of how many pumps you make, you just know to make sure it all goes in her. As the orgasmic haze in your head clears, all you hear are your own harsh pants and Arin's content whimpers, both of you completely spent and exhausted. Arin rolls off you tiredly, your spent cock leaving a trail of white down her thigh. The rest of you leaves her slowly, adding to the mess of her ruined bedsheets. You caress her cheek; no words, only gazes are exchanged before the two of you quickly succumb to sleep.

The two of you wake up next morning to the ringing of a phone, the sun shining in your faces. Arin fumbles around, eventually finding her phone and answering it on speakerphone. "Binnie unnie?"

"How was it? Was he good?"

"Unnie, how can you ask me that!" Arin blushes furiously, embarrassed at being asked in such a straightforward fashion.

"Aha he was good wasn't he?"

Arin looks at you, turning a deeper shade of red before answering, "Yes, he was."

"See, I told you! If he's still there can you remind him our lunch reservation is at 1? Thank you!"

"I got it Binnie."

"Oh oppa, you're awake too? I'll see you later!"

The two of you get dressed, and you help Arin with replacing the ruined sheets with fresh ones, the two of you operating in an uncomfortable silence, neither of you knowing what to say. She walks with you to the door.

"Are you going to be okay? About, you know..." you trail off, now it is your turn to feel awkward, trying to broach the topic of cumming in her.

"Yes, don't worry about me, we all take pills."

"Good, so umm..." Before you can make some sort of lame goodbye, Arin hugs you tightly.

"Thank you oppa, that was the best I ever felt."

"Not at all, I'm glad I could help you." You open the door, preparing to go, but not before Arin leaves you with promises for the future, her hand running sexily through her hair.

"I can't wait to feel that again next time."
