Sorry oppa, something came up last minute, I can't make it to our date tonight... sorry!
It's okay... let's try again next week?
Yes, I'll make it up to you, I promise!
You sigh and put away your phone, Binnie's cancellation leaving you with nothing to do on a nice Friday night. Right after you put away your phone you hear it vibrate in your pocket. Annoyed at the poor timing, you pick up the call and snap. "What?"
"What's your problem? Binnie's oppa, my place, I'm texting you the address, 9 pm, don't be late. Feel free to come naked." Click
Mimi's rapid rap-like response surprises you - it's a call you've been expecting to receive since she caught you with Hyojung, but not quite in such a direct manner. Ah well, you had nothing better to do anyways, might as well be her plaything for the night. You sigh again as you go back to your desk and work, waiting for your boss to leave so that you can go too. The rest of the evening goes by uneventfully - you try texting Binnie to see what she's up to, but she's gone completely silent, not even reading your messages. Puzzled and annoyed, you show up at Mimi's place at 9 sharp.
"Hi Mimi."
"Hi Binnie's oppa, good, you're on time. Come in." You follow her into the apartment, and the aesthetic is definitely unique - simple, practical, and only a little cute, way less girly than Arin's or Binnie's place. "What do you want? Water, cola?"
“Anything’s fine, let’s just do it and get it over with.”
"Come on, don't be like that Binnie's oppa, I’m sure you'll enjoy this too!" She closes the distance to you, her hand rubbing your crotch, feeling your cock through your pants. Frustrated after being stood up by Binnie, you mashed your mouth into hers, taking out your need and frustration on the blonde rapper. She pushes you away, teasing you with a wag of her finger.
"Ah ah ah, my terms, remember? Or should I tell the company about what you did on their property?"
"Fine... I'll have water." You growl in defeat, sitting down on the couch. Mimi comes back with a glass of water for you.
"Also why do you call me Binnie's oppa all the time?" You ask her as you quench your thirst for now.
"Well you're not my oppa, I barely know you."
"Yet you call me here to fuck me?"
"Those two things are not related."
"I- sure, whatever." You give up trying to understand her logic. Mimi's phone rings from the bedroom, and she excuses herself to take it. After what sounded like a hurried conversation and a confirmation, she comes back to you excitedly after a little bit, sticking her head out.
"Okay Binnie's oppa, ready to go, come in!"
"Ready for what?"
"No questions, just come in already."
You step into Mimi's bedroom, and you take a proper look at her...
"Did you change clothes?" Mimi was dressed in a stunning dark blue jacket, matching shorts, and stockings. Her blonde hair tied up, she looked at you seductively, a grin appearing on her blood red lips.
"Why, do you like it?" She comes up to you, her hand going to your crotch again, feeling your cock harden. "Oh yes, I think you do." She grabs you with both hands on your collar, dragging you to the bed opposite her desk. Making you sit down on her bed, she backs off from you, starting some music on her laptop before putting on a slight dance for you. She peels off her jacket, revealing her perky breasts, framed tantalizingly by a purple bra. Jumping on your lap, Mimi straddles you, she brings her lips to your ear.
"You know, I always wanted to try giving a lap dance." Her hips rock and sway above you, undulating rhythmically with the sensual music. She unties her hair, making her look more wild and unrestrained as she stares at you with lust. She grabs your hand, placing it over the stockings on her thighs.
"It's just us in here, you can touch..." You blindly squeeze at her firm thighs, feeling how fit she is from dancing. Your other hand goes to the back of her head, pulling her close to you as you pepper her neck with kisses. Satisfied moans enter your ear, Mimi clearly enjoying the lap dance as much as you are. Her hips grind on you, getting close to your hard cock. She continues to try and tease you, but you've had enough. You wrap your arms around her lower back, pulling her in and down on you, your cock making contact with her crotch. Even through the multiple layers of fabric, you can feel the heat and wetness coming from her core. You rub your shaft along her clothed pussy, causing Mimi to let out soft whimpers as you pleasure her through her shorts.
"Fuck it, I can't stand it anymore." She pushes you back on the bed, her hands going to your pants and pulling both boxers and pants off in a swoop. Your cock stands erect and ready, pointing straight up in the air.
"Wow, Binnie, you're so lucky!" She says to herself, really loudly for some reason. You lean back, watching Mimi shrug out of her shorts and panties, her purple bra quickly follows, joining the pile of clothing on the floor. You stop her right as she makes to take off her stockings.
"No, keep them on, you look way hot in that."
"Really? You like stockings?" She repeats what you said, again really loudly for some reason.
"Yes, just keep them on please."
"Okay Binnie's oppa."
She clambers on to the bed, taking off your shirt on the way up your body.
"I'm not waiting, I'm fucking you now." She says as she lines herself up on your pole - you already feel her juices dripping on to your cock, causing you to throb with anticipation. With one slow but firm drop of her hips she takes all of you in her hot body.
"Oh fuck, you're so big. Tell me Binnie's oppa, am I tight?"
"Shit yes... you're tight."
"Louder!" She shouts at you, raising her hips before dropping down on you again.
"You're tight!"
"Louder!" She slams her hips down on you, the clap of flesh against flesh echoing loudly in the room.
"I said you're so fucking tight!" You grip her hips, half in anger and half in lust, getting carried away with the animalistic nature of the sex. You physically bounce Mimi on you, thrusting up hard into her as you pull her down. Her breasts jiggle deliciously, and you lean forward to capture one in your lips, licking and sucking firmly on her hard nipple. You set a hurried pace, moans slipping out as you enjoy lifting and dropping the petite woman on top of you.
"Wait, wait! I want to change positions."
"Fine, hurry up about it!" You shout at her, frustrated at being stopped. Mimi quickly gets off you before turning around, now facing away from you. She sinks down on you once again, and this time you get straight to work, wrapping your arms around her slim waist and pulling her back down on you. You pump into her from below, one hand on her breast and the other on her hip. You split her in half with your cock, driving up into her as you nip and suck on the back of her neck. You feel her juices coat your shaft and leak out of her with every violent buck of your hips. Mimi’s moans melt together into one long melody of pleasure.
"Is this what you want?"
"Yes! Yes!" Your hand pushes down on her abdomen, making sure you're hitting the spot that brings her mind-melting pleasure, causing her to cry out louder in joy.
"Fucking cum, call me oppa and cum." Your snarl at her. Your other hand goes down to her clit, furiously swiping and flicking over it, rocketing Mimi to a shattering orgasm.
"Oppa!" With a high-pitched wail you feel Mimi arc off your body, giving you a face full of her hair. She freezes in the air, her pussy clamping down hard on you, fluttering and trembling around your tool. As her sweaty body collapses back down on you, you slip out of her, but you're too far gone to care - you rub your shaft furiously against her slippery folds, and the stimulation is enough to tip you over the edge.
"Ughh fuck!" With a groan your lurch up, pushing the two of you up off the bed for a moment. Cum flies out of you in powerful spurts, landing on Mimi's toned stomach, the floor, and almost making it to the laptop on the desk opposite the bed. Both of you end up limp on the bed, two sweaty bodies soaking into her sheets.
"Mmm that was good, Binnie's so lucky..." She gets off you, walking shakily to the desk and picking up the laptop and coming back to the bed, not caring about the cum on her body.
"Did you enjoy the show Binnie?"

"Wait what?!" In the haze of your orgasm you barely process what Mimi is saying. As you open your eyes and turn to the laptop you see Binnie naked on her bed, legs spread, two fingers deep in herself. She is looking straight at you, her eyes unfocused in pleasure. Mimi unmutes the laptop, and you are treated to the moans of your girlfriend close to orgasm.
"Hi oppa- ah!" With a shrill cry Binnie cums on the screen in front of you, coating her fingers with slick as she pulls them out.
"She was watching this whole time... Binnie wanted to watch you fuck me, so she canceled on you today."
"But why?" The thought is confusing, but also arousing. You feel yourself begin to recover already, watching Binnie shaking and coming down from her orgasm.
"I-I like to watch..." You did not know Binnie had this side to her, and you're definitely into it.
"Oh? And how did we do?" You sit up, pulling Mimi to sit between your legs, putting both of you on full display for Binnie.
"It was so hot..." Her fingers drift down to her pussy, dipping into her soaked folds again. Her legs quivering as she goes one, two, then three knuckles deep in herself.
"Did you like watching me fuck Mimi right in front of you?" You mimic Binnie's movements on Mimi, plunging two fingers deep into the rapper. Binnie can only nod, biting her lips as small whines escaped her.
"Hey, I'm supposed to be in charge here!" You hear Mimi complain, but ignore completely - her moans more than give it away that she's enjoying your treatment, the erotic video call turning her on more than she thought.
"Show me what you like to do." You command Binnie.
"I like to touch myself here." Her hand grabs her breast, massaging it.
“And?”
“And here...” Binnie’s gasps out, her other hand playing with her clit. You mimic Binnie's actions on Mimi, drawing similar moans from the older girl. The rest of it is a mess of half-words and groans as Binnie loses herself to the insanity of masturbating in front of both of you. You "help" Mimi follow along, the pleasure causing her hands to be stuck to your thighs, grabbing you almost painfully. Like an obscene version of Simon Says you reflect every movement Binnie makes on Mimi's body, faster and faster. Soon both girls are mere puddles of pleasure, moaning and writhing on a hand in front of each other.
"Oppa I'm so close!" Binnie shouts into the screen.
"Are you close too Mimi?" You ask with a sly grin. She can only look up at you and nod, her eyes wanting more, wanting you to help her join Binnie in climax.
"Cum Binnie, cum for us!"
"I'm cumming!" On Bnnie’s cue you finger Mimi rapidly, your palm rubbing her clit as your fingers find her sweet spot again and again in quick succession.
"F-fuck, me too!" You watch the two Oh My Girl members tense in mirrored orgasms, fluids flying out from both of their stunning bodies - you can't tell if Binnie has covered her camera with her juices, or if Mimi has covered your screen with hers. You feel Mimi quiver in your arms, the strong orgasm rendering her breathless for the moment. Binnie collapses back on her bed, giving you a view of her pink pussy, her honey still slowly flowing out of her. The view is too arousing for you, and you kiss Mimi on the forehead, trying to draw her attention.
"I need to fuck you again Mimi, how do you want to do it?"
"I-..." Mimi's unsure, she was not expecting you to be able to go two rounds. With a grin she figures out what she wants. "Let's give Binnie a show, fuck me from behind." She gets on all fours, facing the laptop.
"Binnie, are you still watching? We're going to fuck again!" She’s too tired to respond, instead giving the two of you a thumbs-up. Mimi wiggles her rear at you. "Come on, what are you waiting for?"
You mount Mimi from behind, leaning over her. You guide your head to her entrance, and with two hands on her hips you pierce her delightful heat once more. You are overwhelmed by her increased tightness, grunting right by her ear and into the laptop.
"Fuck, you're even tighter now!"
"Yeah? You like that Binnie's oppa? Come on, let's go!" Mimi is demanding, pushing her hips back at you, trying to get you to fuck her already. You pull back before thrusting into her powerfully to shut her up, earning a loud moan for your trouble.
"Yes, just like that!" Mimi's cries ring in the room and into the laptop as you set a fast pace. You slap her fleshy cheeks several times, adding to the clapping that occurs with every pound you give her.
"Yes oppa, fuck her like that!" You see through the screen that Binnie has recovered, leaning forward into her camera, her hand thrusting in and out of herself from behind, as if trying to imagine you were pounding her instead. Her moans and wet slops coming through the speakers turn you and Mimi on even further, feeling the blonde tighten even more on you, her cries going higher in pitch. The pressure in your crotch increases as you continue to take Mimi from behind. The whole scene, completely beyond your wildest dreams, quickly send you to your peak.
"Mimi, where-"
"C-cum in me!" The two girls simultaneously scream out their desires, and you throw yourself on to Mimi, flattening her on the bed, making her fill the camera shot entirely.
"Damn!" With a roar you feel yourself unleash everything you have left into Mimi, pushing her deep into the bed. The sensation of your seed splashing and filling her tight walls triggers Mimi's orgasm, her jaw falling open in a silent scream, her expression slack as she shakes and twitches under you. The knowledge that you are filling her fellow member with cum, and the erotic look of pure pleasure on Mimi's face sets Binnie off.
"Oppa!" Binnie's hips buck violently as she cums, her body rocking forward with every wave of pleasure she imagines you delivering to her, before finally collapsing on the bed in exhaustion as well.
For a while the only sounds that are heard from the three of you are pants and gasps, trying to get oxygen back in your bodies, having previously been so filled with pleasure, cum, and fingers.
You hear a faint whisper coming through the laptop. "Show me what you did to her." You get Mimi to sit up, supporting her tired body against you. You spread her folds for the camera, showing the white mess you made inside her beginning to leak out.
"Damn, you came a lot... thanks oppa, that was such a good show." With a raise of her tired arm Binnie hits a button on her laptop and her screen winks out, disconnecting the call. You feel Mimi sink further into your arms, and you grow a little concerned for her.
"Hey, are you okay? Sorry, was that too much?"
"No no... Binnie's right, that was such a good show, I feel so full, and I'm so... tired." With her last word she slips out of your embrace and collapses on to the bed. You gently move her so that she is lying on a pillow - feeling drained of cum and energy yourself you fall next to her, pulling the covers over both of you. The laptop enters sleep mode just as you do.
--The next morning--
You wake up to the smell of breakfast and the sound of a reprimand as you exit Mimi's room.
"Hey, put some clothes on before you eat!" You tramp back to her room, throwing on your clothes before taking a seat at the dining table and eating the porridge Mimi made.
"You're a good cook!"
"Thanks, I'm probably the best among the members."
"That's great." You eat the rest of the meal in silence, unsure how to bring up the crazy night. "Hey so.. about last night-"
"We're even, I'm never telling the company about you, that was far beyond what I expected, Binnie's so lucky."
"No, I'm the lucky guy."
"Yeah, maybe you are, you get to fuck all of us, and the company even allows you and Binnie's relationship."
"I totally agree." You finish your breakfast, helping Mimi clean up before heading out, the two of you having your own places to be. Mimi stops you before the two of you part ways.
"Hmm, I think we're more than even..." Her hand goes down your body and to your crotch again. "In fact, I think I owe you after last night. You have my number, you ever want me to pay you back, you let me know, oppa."
"You're impossible."
"I know." She blows you a goodbye kiss before heading out, her hips swaying sexily as you watch her go. Shaking your head, you walk out, ready for another morning and another day. Your phone vibrates in your pocket, and you check your phone to see a message from Binnie.
I think I want to make it up to you today, I want to get some “filming” done. Look what I got ;)
She sends you another message, a picture of stockings. Damn, you're not sure if you're ready for another night.
