    "What size soda would you like?"

     

    "I'll get the XL."

     

    "Really unnie? That's a lot of sugar!"

     

    "It's okay, I'll just have to workout more."

     

    The ICHILLIN' members look at their leader weirdly, walking away with soft drink in hand, oversized clothes hanging off her.

     

    "Is Jiwon unnie doing okay? She's been... Oversizing everything."

     

    "No idea, not sure what's up with her."

     

    Meanwhile, Jiwon texts her most recent paramour.

     

    Are you free tonight?

     

    Jiwon had met him at a club, her friends had finally pulled her out for one night, and she had dressed as plainly as she could, in a blouse and jeans. And yet through the crowd they both stood out to one another—to her he was hard to miss; to him she was the most understated person at the club, her outfit quiet but the lines contained within screamed out, and he had to talk to her.

     

    "Hi, can I buy you a drink?"

     

    Jiwon turned around, and then had to look up. He towered over her, almost a whole head taller. He had stood out to Jiwon quite literally earlier, peeking out over the crowd waiting to get in the club, and now that he was up close, the difference was even more startling. Good looking too, Jiwon added to herself.

     

    "Sure, why not, surprise me."

     

    He gets her a mojito, the cocktail glass seemingly small in his hand, and yet when he passes it to her, it magically grows to a normal size. They get to talking, the friends who brought her out seemingly forgotten and disappeared into the human mass on the dance floor. He cocks his head that way.

     

    "Wanna dance?"

     

    Dance they do, the anonymity of being in the crowd letting both of them be more daring. His hands find her hips, marveling at her figure, and she finds his arms, feeling them up as she grinds against him. Jiwon's temporarily startled when she feels something else, and the next grind against him is more insistent, searching and confirming—he's big. A small groan floats into her ear, the grip on her hips tightening.

     

    "What's your name?"

     

    "Jiwon."

     

    "How about we take this somewhere more private, Jiwon?" It doesn't take long for Jiwon to come up with an answer—it had been a while since her last fling, and living with her members doesn't make it any easier. She grabs the large opportunity with both hands.

     

    "Your place?"

     

    They pull their own disappearing act, reappearing at his apartment with a loud crash of the door. Jiwon jumps into his hands as soon as appropriate, which is when the door closes, and she moans into the kiss while he brings them to the bedroom, large hands squeezing her ass the whole way.

     

    "Eager?"

     

    "You're one to talk," she chides him, feeling him pressing against her insistently. Still in his arms she unbuttons her blouse, delighting in his throb against her when she discards the piece of clothing. Jiwon is tossed to the bed as he pulls his shirt off, and Jiwon can't help but bite her lower lip, ready for what is to come. He curses softly as she wriggles out of her jeans, admiring her figure—he had truly gotten lucky tonight.

     

    "You're so fucking hot," he murmurs, kissing her as he reaches behind to undo her bra. It comes off without resistance, and while her arm automatically goes to cover herself, Jiwon pulls it away quickly, letting him take her in as she runs a hand across his chest, feeling how fit and muscular he is.

     

    "Make me feel hotter." A request that he would happily fulfill. His hand seems to cover her belly, pausing right above her panties. A silent nod later it dives under, two thick fingers coated almost instantly in slick. Jiwon groans at the stretch, even this was more than she was accustomed to. His fingers are long too, seeming to tickle right at the base of her spine when he curls them.

     

    "Oh! That's—" she quickly covers her mouth. Maybe it has been a little too long, but Jiwon leans into the stretch, her back arching off the bed to try and drive herself deeper on to him, she's so close already!

     

    "You're way too hot for just fingers." Jiwon backs away from the edge, and when her eyes are open again she's staring at it, no him, no, it, straight in the face—it's big, longer than the toys she's tried, certainly thicker, and she definitely wants it inside her. Her mouth is already open before she realizes what she's doing, and she lets herself do it, stuffing her mouth with his meat. "Oh fuck, that's good." Jiwon can only let out a huff in reply—he looks big and feels bigger, and she has to stretch her jaw stretch to accommodate him, her teeth lightly grazing his shaft. She settles for his head, tongue swiping across it, tasting his saltiness. She tries to go deeper, but she's still some way from his hips when she can feel her gag reflex kicking in, and with a gasp has to let him go. Maybe some other time she'll try again, but she knows one way she can take him without gagging.

     

    "Wait, let me get a condom," he says, and Jiwon blinks, as if in a trance, panties already halfway down her legs. How could she forget? She was ready to just take him raw! She gives a slight nod of embarrassment, but her eyes are glued to his cock as he stretches a rubber over it. As soon as it's on she's on him as well, hand barely fitting around him as she points it cuntward.

     

    "Hnngk!" Jiwon feels the stretch immediately, her entrance shoved open by the sink of her hips.

     

    "Slowly, you look so hot." Taking my cock, he adds internally, watching the beautiful girl he just met at a club bite her lip and sink a little more on to him. She's tight, her walls rubbing against his tip as she keeps going down, small bolts of pleasure going through him despite the rubber. Soon Jiwon's on her knees, having taken a few inches and with more to go.

     

    "Do you want me to be on top?"

     

    "No, it feels good like this..." She gyrates her hips, trying to screw herself quite literally on to him. Jiwon braces her hands on his chest, leaning forward more and more as she pushes herself down. A small shift of his hips, and Jiwon yelps into his mouth as the last inch is hilted inside her.

     

    "You okay?"

     

    "Yeah, you're just really big," she mumbles into his neck, and he was going to tell her to take her time, but—

     

    "And I fucking love it." There's an audible clap of flesh as Jiwon slams her hips back down on him, making him moan and her cry out. She tries to clench around him, but her muscles don't move, like there's no give to the hard rod of meat inside of her, her walls so overwhelmingly stretched and pushed apart. A low "Fuuuck..." of relish is all she can muster, her mind barely able to handle the pleasure he is giving her. Jiwon's hips move with a mind of their own, and that's good because her pussy's fully preoccupied with him inside her, especially when he begins to thrust upwards, hands on her waist easily moving her up and down his shaft.

     

    "You feel incredible," he gasps, marveling at how incredible she looked as well—Jiwon's hair is flying as she begins to bounce harder on him, adjusting to his size better now. Her tits move too, her entire body alternating between arching her back when she's jammed full of cock, and curving forward, letting her brace on him as he pulls out. Jiwon's so light that he can push his hips up in the air, letting gravity help fuck her even harder, making her scream on this spine-tingling rollercoaster.

     

    "Oh fuck, oh fuck you're going to make me cum, you're going to— Ahhh!" Jiwon collapses on top of him, screaming into his chest as her orgasm slams through her. She feels an arm wrap around her waist, pressing her against him belly to belly, and the cock pounding into her begins throbbing, prolonging her peak as he's arriving at his.

     

    "Shit Jiwon, argh!" She's so stretched she feels every pulse inside her, a sudden bulb of warmness felt as the condom is filled, his last few thrusts finally growing weak and coming to a rest. There's a dull buzz in her head, as if to say Yes, now we're satisfied! She lays on his chest for a few moments, before a different kind of dull buzz brings her back to reality.

     

    "Where's my phone?" Jiwon scrambles off his body, finding her purse and fishing out her phone. "What is it?"

     

    "Unnie where are you! It's almost curfew!"

     

    "I'll be a little late, make up something for me." She hangs up and whirls around, finding him holding up her clothing.

     

    "I guess a round 2 is out of the question? Who still has a curfew though?"

     

    "I-I'm an idol, so... Yeah." His eyes widen, suddenly understanding how she found her way to his place.

     

    "That explains things. Must be hard to find some time for yourself in a dorm."

     

    "No I don't— You felt big and—" Jiwon shuts her mouth immediately, ignoring his beam and trying to get dressed quickly.

     

    "You felt good too, so much so that I want to see you again. How about it? Would be easier than trying to find you at a club next time."

     

    "Yes! I mean, yeah, that works for me. I'll let you know." Jiwon tries to play it off, but the spark when he touches her hand to pass her phone back is undeniable.

     

    "Sure, you're the busy one, hope to see you on TV."

     

    "Yeah um, see you soon." She hurries back to the dorms, and she's grateful that he didn't leave any marks or hickeys earlier, but he did leave his mark in her. That night Jiwon felt a good kind of sore, not from working out too much or going too hard in dance practice, but from a good thorough fuck. She never got that from her fingers or her toys, neither of which are big enough to quite satisfy her. She slept better that night than she ever had, and she woke up the next morning with one thing on her mind.

     

    She'd have to see him again.

     

    So she does, several times, each time leaving his place sore and happy. He was accommodating—when she needed a quickie, he'd let her bounce on him, his fingers rubbing her clit to help her along. A bottle of water and a kiss, and she was on her way out, toeing the line between casual and efficient. On days she knew she had the next day off, Jiwon let him have his way with her, delightfully screaming her head off as he fucked her silly, using her as an additional wrapper to the condom around his cock. Nights where her feet spent more time in the air than on any bed or floor were the best, stretching her to her limits as she's either pounded into the bed, wall, or door; or carried and bounced haplessly on his cock, cumming the whole time. She's often bed-ridden the next day, hips sore and walking funny when she had to move, but otherwise just ordering takeout and sighing as she remembers the previous night. She's taken to returning to the dorms in his oversized clothes, just to hide the marks left from the night before, and so far she's managed to pass it off as her changing fashion sense; if she has to take a bit of flak from her members, so be it.

     


     

    Are you free tonight? This was looking like one of those nights, as Jiwon checked her schedule for tomorrow and cheered internally when she found it blank.

     

    Yeah but it'll have to be outside, friend is sleeping over at my place

     

    Drunk friend he follows up, quelling the unexpected jealousy in Jiwon's chest. She figures out the next best solution, a love hotel in between the two of them, far enough that no one in the area would recognize her going in, but close enough that she could get back before anyone notices.

     

    Meet me here at midnight Nervously Jiwon waits for her members to fall asleep or sneak out themselves, and when she arrives fifteen minutes late she's thankful to see his big form still there.

     

    "Sorry, took a while to get out." She pulls her mask down to smile at him before slipping it back on, maintaining her cover.

     

    "No problem, this the place?"

     

    "Yeah." The two of them head into the love hotel.

     

    "Welcome, how many hours?" The guy at the desk drawls, not even looking up, until he doesn't hear any response. "Hm?" The two of them fidget—this never came up before, how much time would they spend "together"? This felt more official all of a sudden, a young couple stealing away for some privacy.

     

    "Er, one night?" Jiwon offers nervously.

     

    "70,000 won."

     

    "Here." He takes the money and slides a keycard and some toiletries to them without a second glance.

     

    "Have a good night."

     

    They are silent as they walk down the corridor to their room, ears unconsciously perked to see if they can hear anything, both excited and nervous.

     

    "This is us."

     

    "Uh huh." The two of them sit on the bed, neither making a move just yet.

     

    "This is awkward," he offers. "Should we just try another time?"

     

    "No! I mean, you already spent the money for this place." Jiwon swings her legs across him, getting in his lap. "Do you want to do this?"

     

    "Yeah." His arms wrap around her waist, hands already slipping under her t-shirt.

     

    "Okay, then let's not think too much." She lets her weight sink down on him, planting herself there as they make out. "I want your big buddy."

     

    "And I want your tight body."

     

    "You have it, gotta get our money's worth okay?"

     

    "Yeah, we will." Tops are pulled off, bra undone, underwear removed, and then— "Condom." She rummages through what was given and finds some, but they don't fit right on him, only one of the sizes offered barely fitting.

     

    "Does it hurt?" Jiwon asks, watching the rubber stretched tight around him.

     

    "No, tighter than usual but it's fine, I think." Without another word she slides on to him, a soft moan leaving both of them.

     

    "I missed this, uff the stretch..."

     

    "Tight as always, fuck!" Wordlessly she grinds her hips down on his lap, letting herself be slowly stretched just the way she likes it. His hands react to her movements, going from her waist to her ass, squeezing and spreading them as she moves, as if trying to get deeper in her. She locks her feet around his lower back, willing herself to slam harder and faster on him. Her waist is held once more, and he's now pushing and pulling her on his dick, making Jiwon move faster against him.

     

    "Faster, harder! I'm gonna cum!" She yells into the kiss, muffling herself against his lips. A firm squeeze of her hips, and a rough jam on to his cock, and both of them finish together, moans of relief as the awkwardness of doing it in a love hotel fades—this is sex as they were familiar with. Jiwon eyes the filled condom curiously—the load looks bigger in the smaller rubber, or maybe he hadn't done it in a while?

     

    "It's been a bit since we last met," he confirms a little sheepishly.

     

    "Yeah, I was busy." She tears open another condom, stroking him until she can roll it on again. "But we have to make the most of our money right?"

     

    "I have plenty left."

     

    "Good," Jiwon lays on the bed, legs spread and inviting. He doesn't need a second invitation, and she gasps as he enters her a little too quickly—she's missed this feeling!

     

    "We're here to fuck. So, fuck me." He understands the task perfectly, and immediately they're testing the bed's integrity and finding it wanting, the loud creaking of the springs only adding to the moans she begins to let out.

     

    "Oh fuck, just like that, stretch me out, you're getting so deep!" Jiwon's getting so close, her breaths cutting short on every thrust, he makes her cum so damn fast sometimes—

     

    He stops. She opens her eyes, only to see him roll her over, their faces pressed together and into the pillows. He slides in her again, and this time with the pillow acting as a proper muffler Jiwon screams, his cock rubbing at her g-spot and then going far past it. He's humping her incessantly, the poor bed crying out as Jiwon screams into it, she's so tight, so fuckable, so... wet?

     

    "Don't stop, don't stop! Hnngh!" Jiwon's legs kick up when he halts abruptly. "No I'm so close, keep going!"

     

    "Fuck wait, Jiwon wait! The condom ripped." He grunts through gritted teeth—feeling her raw was something else, his sensitive tip being squeezed by her slippery walls directly. He can feel her contracting erratically, even if he's staying still, they're both so close!

     

    "No, don't stop!" They're spooning now, Jiwon keeping him inside her when he tries to roll off. Her arm is on his neck, and a leg is hooked back against his hip, trying to keep him as close to her is possible. "Please keep fucking me, I'm going to cum, I'm going to cum!"

     

    "Nngh fuck, are you sure, I should pull out!" But he's getting even deeper in Jiwon in the new position, and she drags his hand over her mons. The blood's pounding in his head, and he can feel himself ramming deep into Jiwon. Curled against him she's wracked by spasms, pre-orgasmic sparks before she combusts. She should probably let him pull out, but Jiwon's so close to her peak, and right now good-looking, fit, and tall, not to mention big is checking all the boxes in her lizard brain to being bred by him. He's literally at her door, she should just let him in and—

     

    "Hnngh!"

     

    A blushing couple walks by the room outside, hearing the lovemaking a little too clearly. They hear Jiwon begging to cum and his protests mixed with moans and grunts. The girl's jealous of Jiwon—she never feels that good during sex; The guy's jealous of Jiwon's partner because—

     

    "Just cum in me, cum in me!"

     

    Unaware of their unexpecting eavesdroppers Jiwon's scream matches her lover's moan in volume, an illicit wave of pleasure rushing through her as his thick seed surges into her for the first time. She has always felt the condom tip fill when he's blowing deep inside her, vaguely wondering if it'll ever pop, but this time she feels all of it, every single drop that was stored in his balls, pouring into her womb.

     

    "Unngh yes!" "Fuck it feels so good!" Both of them gasp at the feeling of cumming raw together, bodies trembling and sweating. He slips out of her, the condom tattered and torn over his shaft, much like their mental faculties.

     

    "Ahh!" Jiwon feels two fingers shoved into her, moving the cum around, digging. He removes what's left of the condom from inside her, his digits creamy and covered in his own cum. She cleans it off gratefully, and the two of them just lay there, processing what happened before reality hits.

     

    "Damn, I'm sorry, I should have pulled out, should have stopped," he buries his face in her neck, kissing her lightly in apology.

     

    "No, it's fine, I got carried away too. I'm safe, I'll take a pill tomorrow too just in case. You're clean right?"

     

    "Yeah, you?"

     

    "Yes, you're the only one I have sex with." The words slip out of her mouth before she could stop herself.

     

    "Same." He wraps his arms around her, spooning her fully.

     

    "Really? Since when?" she asks quietly.

     

    "I forget, since we met?"

     

    "Thought you would be picking up girls left and right in the club regularly with that big thing of yours."

     

    "They're not as hot, or tight."

     

    Jiwon chooses her next words carefully.

     

    "I can't date right now, but if you're willing to keep things exclusive physically, I think we can forego the condoms." Try as he might to restrain himself Jiwon can feel him tremble, his cock stiffening already between her thighs.

     

    "What if you're not safe?"

     

    "Just try to pull out, and you stock up on morning after pills, at least your cock won't rip a pill up."

     

    "Yes ma'am." With that out of the way, Jiwon turns to face him, kissing him and stroking his shaft slowly.

     

    "Now let's continue making the most of our time here, hm?" He tops her easily, pushing into her raw for the first time. "Oh fuck, it's so hot inside me!"

     

    "You're so wet!" he gasps, the sensation of her walls gripping him utterly exquisite. He feels the load from earlier—Jiwon's downright creamy from being filled up, and there's nothing he wants to do more in the world than to top her off right now.

     

    "Haah! Harder, fuck me harder!" They might be in a seedy love hotel, but Jiwon's in heaven, feeling every throb and pulse of him spearing her open. His tip brushing over her walls like nothing's in between them, because there was nothing in between them. She wraps her legs around his hips, biting her lip to stifle her cries—she screamed just now because she wanted to cum so badly, this time she might scream because she's going to cum so hard.

     

    "Oh shit..." The sight of Jiwon's lip bite is fatal, instantly ending his stamina and swiftly topping her womb off with his cum. The additional heat sends a bolt up her spine, and she's cumming with him, a scream screeching through her teeth as she milks him for every last drop. "Fuck, I came too fast—"

     

    He looks at Jiwon, grabbing her stomach and wincing. "What happened? Did I go too hard? Are you hurt?"

     

    "No, ah! Cramping—" she hisses through her teeth. "Came too hard!" Unsure what to do he places his hand on her flat tummy, massaging it and praying it helps. Jiwon takes deep breaths, willing herself to relax as she continues to twitch in soreness. As she relaxes his load comes dripping out, continuously leaking on to hastily placed tissues.

     

    "Fuck... That was a first," she mutters. "I feel so sore."

     

    "You keep gripping me too tight, that's why."

     

    "Can't help it, you're too fucking big! But don't be sorry," Jiwon assures him she's fine. "Big things are good in small doses."

     

    "Everything in moderation eh? We should just go back and rest then, would be better to sleep in your own bed to recover, this bed sucks."

     

    "I— Yeah you're right. Let's just shower quickly, I can't smell like this when I go back." The two of them share a playful shower, one with no finish as they tease each other for the next encounter.

     

    "Let me see you back to the dorm, just in case."

     

    "No, someone might see us!"

     

    "No one's up this late at night."

     

    "Precisely why I can find my way back myself."

     

    "Precisely what anyone that's still up this late would want! I'll go with you until you're one block away?" Jiwon reluctantly agrees, and as the two of them exit the love hotel they realize they could hear quite a bit going on.

     

    "Do you think people heard us?" Jiwon wonders.

     

    "Probably."

     

    "Ugh, we'll need to pick a different one next time."

     

    "I won't have drunk friends staying over any more from now on, promise. Don't forget to take the pill."

     

    "I won't, just make sure you have some when I come over."

     

    "Mmhmm, see you soon." He leaves a chaste peck on her forehead, causing Jiwon to blush harder than ever.

     

    "Go!"

     

    The next day three boxes of unopened condoms are left out for anyone to take, they read: XL, XL, XL.

     

    Who wants it?

    Author's note

    Always found E.Ji extremely pretty (and hot) and their latest comeback XL (Extra Love) is very nice, so thought about making it about being a bit of a size queen/liking big cocks, or a size difference at least lol. Of course I took too long to write it so their comeback is done already, but do check out the song, and thanks for reading!
