"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.
