    You sigh and check the next chat.

    Message Read

    You sigh again and toss your phone on the bed in disgust. Two ghosted matches in a row. You get on Youtube, planning to watch some random cat videos to take your mind off things. When you are three videos in you receive an email from... your dating app? Curious, you open up the email, and it reads.

    Bored on your Uber rides? Awkward driver doesn't want to make small chat? You've been invited to join Fromis, an exclusive dating/ridesharing app all in one. Get to know someone new as you go! Ridesharing is more fun with a person or two - find someone with similar interests and make a new friend while you get to your destination!*

    The pitch is whatever, a few other apps have tried something similar. You check out the app, and notice that the model in the preview screenshots is very, very attractive, so much so that you install the app on a whim. You make a quick profile and take a picture of yourself. There were few users on it, but the... nine? girls you've seen so far were all extremely hot. You swipe right on all of them. No immediate responses, but that's to be expected, you shrug and place your phone on your desk, ignoring it and going back to watching random cat videos.

    An hour later, you hear your phone vibrate, and you see the message.

    You have matched with Saerom!

    You tap the notification, and are surprised at the sight of that same model from the screenshots in front of you.

    Hey! I didn't know the model herself used the app.

    Oh you saw that? Yeah...

    I'm surprised you even need the app. You joke.

    Haha, I also own the app if you believe it.

    Really? Wow that's impressive! So now what, Miss App Owner?

    Now, we go on a ride, your place or my place?

    Your eyes widen and you nearly choke on your water. But before you can reply, she continues.

    It's easier if we just meet at one of our places and then ride together, where are you planning to go? You exchange locations with her and where you want to go before she follows up.

    Oh, come to my place then, it's further out, but that means a longer ride to know each other :) Does Saturday sound good? You don't know what to make of that, but hell, you accept her proposal anyways and agree to a Saturday trip.

    Great, see you then!

    You can't wait to see her, and you exchange a few texts with her throughout the week. Thankfully she doesn't ghost you, always replying to you fairly quickly.

    The day finally arrives and you dress up nicely for your date ride with Saerom. You take the short subway trip to her place and show up at her door, right on time. You knock lightly on the door, and it quickly opens.

    "Hi! You're right on time, I like that!" She flashes you a gorgeous smile.

    "Hey, wow it looks like I'm a little overdressed..." You manage to look past her angelic face and scan her simple casual outfit... almost too casual actually - she's dressed in a simple oversized t-shirt, wearing boy shorts that accentuate her long legs, perfect for her modeling career.

    "Oh not a problem, come in, come in!" Saerom waves you in and closes the door behind you.

    You look around the apartment as she leads you in, and believe in her being the app owner - it is surprisingly spacious, and the neighborhood you're in means it can't have been cheap.

    "You're not kidding about the app owner thing are you?" You ask her, impressed at her living situation.

    "No I wasn't! I made an app before this called Love Bomb, and that blew up, no pun intended, so here I am. Come, sit down with me!" She pats the seat next to her on the sofa.

    "S-shouldn't we get ready for our ride? I can wait outside if you're not comfortable changing with me here." You offer.

    "No no, we have plenty of time for that later, come join me, let's get to know each other first."

    You're puzzled - shouldn't that happen while on the trip? You sit down anyways. Saerom is easy to talk to, always listening to your every word, her eyes bright and engaged. You find out about her background, switching between model and app developer with her small group of friends, putting out a bunch of fun apps like the aforementioned Love Bomb, and an ASMR app called Feel Good. You tell her about your background, much more mundane and "traditional", for lack of a better word.


    As you talk, you can't help but notice Saerom inching closer and closer to you on the couch, her knee soon touching yours, close enough for you to notice the lack of imperfections on her flawless face.

    "Uh... should we get started on our ride?" You ask, backing away from her a little. Saerom moves even closer to you, her hot breath on your cheeks, a hand on your crotch in a flash. You harden right away, having her in such close proximity to you, her hand already rubbing you over your pants. She smirks at you, satisfied with your reaction.

    "Yes, we should." The distance between your lips shrinks to zero, and you taste her lipstick on your tongue as she opens her mouth, allowing your greedy tongue access, while she plunders yours in return. You find yourself leaning on the couch as she pushes you down on your back. She whispers in your ear before continuing.

    “A-are you sure?” You blurt out, surprised at the speed things were progressing.

    "In case you didn't know... Fromis stands for From Introductions to Sex, which is what we're going to do right now." You can't help but moan as she attacks your neck, her hands furiously working your shirt, unbuttoning the first few buttons off before ripping the last ones off. She allows you to get rid of the shirt, and you pull on her t-shirt in return.

    "I'd say you are the one overdressed now." Saerom winks and bites her lower lip, making your heart stop for a moment before she pulls the large t-shirt up and over her head, revealing her lack of bra, along with an amazing figure and perky breasts - she was probably the fittest and most attractive woman you've seen, and you already can't get enough of her.

    Your hands go to her body, feeling her toned abs and relishing in the feel of her smooth skin. With a mind of their own they quickly move upwards, grasping at her chest, kneading her breasts and rolling her stiff nipples gently between your fingers. The little noises escape Saerom continue to increase in frequency as you continue appreciating her body, leaving kisses all down her neck and across her shoulders.

    "I can't take it any longer!" And neither could you as she reaches for your pants, quickly working them free from your body. She wiggles her shorts off, leaving you both in your underwear, a visible wet spot on her plain white panties.

    "God I want to cum in you so hard..." You rasp, sitting up from the couch and trying to switch positions with Saerom. She pushes you back down with a palm on your chest.

    "Easy there, I don't want you to go blowing your load early. Let's play a game... I'm going to ride you, and if I feel you cum before me, I'm getting off you, and you can have fun splashing yourself with cum and cleaning up your own mess. If I cum before you, I'll suck you off."

    "And if you cum multiple times?" You challenge her with a smirk.

    "Then you can do whatever you want to me, cum wherever you want..." She sits on you, grinding the wet fabric of her panties against your boxers. "But it won't happen."

    "We'll see about that..." Without a further word she tugs your boxers off, and quickly slides her drenched panties off her legs. You hold your breath as she grasps you with a hand, feeling her dripping heat against your tip, making you bulge further in anticipation. With her other hand on your chest, she slowly lowers herself on to you, both of you rendered speechless by the tightness of your fit in her. Saerom lets out a moan of satisfaction when she finally feel your balls press against her, knowing that she has taken you all the way.

    "Ah... it's been a while, this is so nice..." She moans dreamily as she rocks her hips back and forth on your cock, letting you watch her move hypnotically in pleasure. Your eyes follow her hands, watching them rove over her toned muscles and creamy skin, feeling yourself get even more aroused under her riding. You moan when she sinks down particularly hard on you, and you have to catch yourself from drooling at the sight of Saerom grinding on you with purpose.

    "Think you can last a little longer for me? I've missed having a cock in me... can you feel my pussy gripping you? It's so hungry for you, it hasn't had anything so big..." She whispers seductively, while beginning to move faster on you. "Or so thick... you're going to have to hold on if you want me to taste your thick cum, I bet you taste delicious don't you? I always swallow."


    Saerom smirks at your unfocused gaze on her. "Or are you going to cum already, that's fine too, I'm so tight aren't I?" She grinds a moan out of you as she tightens her muscles around your cock, all your senses are hypersensitive, you can just feel her juices trickling down your shaft. "And you made me so wet already, it must be so hard to hold on."

    "I-I-" You stutter, desperate to hold on, sensing that Saerom is just as close as you are, her grinding beginning to get more rough and erratic. Both of you are reduced to gasps and moans as she ceases all her dirty talk, too busy with the pleasure she is extracting from you.


    You watch her eyes close, her riding rising to a harried pace before her head snaps back, sinking herself fully down on you and freezing in place. A strained moan escapes her as she shudders through her orgasm. You grit your teeth and hold on through the sudden wetness, watching her lean stomach twitch and flex as the pleasure works it's way through her body. When she is eye-to-eye with you again you ask her. "Good?"

    Her reply is accompanied with a satisfied smile. "Amazing, now let's work on finishing you off."  She tries to get off you, but you hold her hips, keeping her in place as you sit up.

    "No... I really want to cum in you." You pull her in for a kiss as you begin manipulating her hips, making her begin grinding on you once more, her tight walls dragging tantalizingly over your throbbing shaft.

    "Ah! I'm sensitive!" You give her a knowing smile, a smile that meant "I know, even better." She trembles and tightens on your shaft again. This time you are more active as she rides you, kissing her all over, leaving marks of passion on her neck, your hands active over her body, squeezing her breasts, her butt, roaming all over her back as you lock her in with a kiss. Your actions overwhelm Saerom, and soon she breaks the kiss, hugging you and whimpering directly into your ear.

    "It's so easy, just cum for me, and you'll feel even better when I cum in you, that's what you want too right?" You whisper, corrupting her thoughts of holding off her orgasm. "You can feel me throb, I'm getting even bigger and harder for you, I want to cum so badly right now, but I'm holding back for you." Your hand goes down between your bodies, making Saerom's breath catch when your fingers find her clit, rubbing against it as you thrust up into her.

    "Don't you want to feel me explode in you? I have such a large load built up, I can fill you up really nice..." The prospect of that fills Saerom's mind before it goes blank, your handiwork quickly bringing her to a second climax. She is even tighter this time, her body trying to milk you for the large load you promised her, but you manage to hold on. You get up off the sofa, gravity driving Saerom even deeper on to you, adding a few more waves of pleasure to her peak. You find her bedroom and put her on the bed, making her whine when she feels the lack of your cock in her.

    "A-aren't you going to cum in me?" She asks, confused and horny for more.

    "I will, on all fours please." Saerom obliges you, getting on her hands and knees on the edge of the bed. You rub your shaft between her cheeks, and Saerom gasps as she feels you press your head against her other hole. "W-wait! Please not there!" She calls out in a panic.

    "You said I could do whatever I want." You point out the terms of your agreement.

    "I-I... I'm not ready, please?" She pleads. You make Saerom squirm for a few more moments as you continue to rub your throbbing cock between her butt cheeks, enjoying the smoothness of her skin on your shaft. You grab her shoulders, pulling her up against you as you whisper into her ear.

    "Fine... but next time, this is going up your ass-" You push her back down on the bed before plunging yourself in her hot wet pussy. "All the way!"

    Saerom grunts in pleasure, biting down on the bedsheets as you take her hard and fast - your fingers are definitely leaving bruises on her hips. A prolonged moan escapes her when you find her perfect little spot, and you pound down on it, driving your hips into her again and again.

    "Oh god yes, right there!" Saerom feels her fingers go numb from gripping the sheets too hard, her mind spinning as you have your way with her, fucking her with deep strokes, pulling out almost all the way before thrusting back in, hitting her right where it makes her scream. On a particularly loud cry you watch her fingers grip and release the sheets repeatedly, her velvet muscles doing the same thing on your shaft as you rocket her to another orgasm. You keep pushing, making her thighs jiggle and quiver with every clap of your flesh against hers. As if trying to wring all of her juice out of her you squeeze her cheeks roughly while you continue rocking your hips, wanting to prolong her pleasure before you inevitably lose it yourself.

    "P-please cum for me! I can't take much more of this!" Saerom whimpers in surrender, still recovering from her third straight orgasm. That is enough for you and you thrust into her hard one, two, three times before pulling out.

    "Wha-" Before she can finish her thought you push your cock right against her other tight entrance, penetrating her just a little bit, and the visual of it is enough to tip you over the edge. You gasp and shoot thick cum deep into her ass, making Saerom groan in surprise at being filled. You cock throbs and sprays the rest of your cum all over the surrounding area, coating her pussy and ass with a layer of white. You barely manage to stay standing while Saerom's strength finally gives out - she collapses on to the bed, allowing you to admire the mess you've made between her legs. The two of you rest on the bed for a few minutes, trying to clear your heads of the pleasure.

    "Sorry, was I too rough?" Saerom winces as you touch her hips, the skin red where you gripped her earlier, but she smiles and shakes her head.

    "No, I'm going to be sore, but it's going to be a good sore." She gingerly gets up off the bed, walking shakily to the bathroom. "Come join me in the shower?" You feel yourself already beginning to get hard again at the thought, but you shake your head.

    "Maybe not, I don't trust myself to not pounce on you again." She smirks seductively, giving you that perfect look of innocent naughtiness.

    "That's the plan. I said I was going to be sore." She enters the bathroom, leaving the door open, and you soon hear the shower start. After a minute of zoning out, the meaning of her words hits you hard, like you've walked into a brick wall, and you quickly join her in the running shower.


    "Took you a while..." Saerom gasps as you press her against the cold glass shower wall.

    "Sorry."

    "I'll forgive you if you fuck me right now!" As soon as the words leave her mouth you slide your shaft into her, and you swear she is wetter inside than outside, even with the shower drenching the two of you. You pull her hair to one side, allowing you to kiss and suck on her neck while your hands help her "clean", admiring the smoothness and fullness of her thighs, her flat abs, and her round squishy breasts, perfect handfuls for you to squeeze. You play with them as you slowly thrust in and out of her, and you’re sure her nipples could probably cut the glass with how turned on she is.


    You screw Saerom into the wall, making her get on her tiptoes with every thrust, gravity adding to her pleasure as her legs begin to go weak, allowing you to damn near wear her on your cock. Saerom's fingers draw short vertical lines on the misty glass, scrambling for grip, but failing and slipping deeper and deeper on your cock with every thrust.

    "O-oppa fuck!" Her scream echoes in the shower stall when she orgasms, her entire body shuddering and twitching, sending water flying. You hold her tightly against the wall, making sure she doesn't slip until you finally feel her legs move against yours, regaining some of her strength. You feel her hand grasp your chin, her lips searching for yours. She kisses you again, except this time, under the showerhead and running water, it is more passion than lust, and you feel yourself throb inside her, even closer to your own climax. You try to move again, wanting to resume your thrusts, but she stops you, turning off the water.

    "Let's take this back to the bed."

    "Really? I'm so close..." You groan in disappointment. She ignores you, grabbing a towel and drying herself off quickly. She lures you with the sexy sway of her hips as she discards the towel on the floor. The sight of her wet hair sticking to her face as she looks back, and her butt shaking alluringly when she walks away is enough for you to follow her back to bed, stopping only to dry yourself.


    When you get to the bed Saerom is sitting up against her headboard, the rest of her sinful body covered by her blankets, one inviting lip bite and a glance is all it takes to get you in bed. She pulls the covers up and over, shrouding the two of you. She searches for your lips once more, her kiss more needy than ever, her hands more daring, roving over your body, gripping you by your arms and pulling you down on her.

    "Hi..." she whispers, and you're not sure if it's the dim light under the covers or the wet hair, but for the first time Saerom seems... Shy? She notices your hesitation, taking you aback with her follow-up. "Sorry, too much?"

    "No, just... I didn't expect it."

    "I-I wanted to see if we are compatible in bed, a-as partners." The words rush out of her mouth, her face turning red even under the blanket.

    "Really? After what we just did?" You ask, a little incredulous. Saerom doesn't say anymore, avoiding your gaze, a whiny but cute sound leaving her lips as she tries to persuade you. Anything she does is very persuasive of course, and the thought dating her is an added incentive to do well.

    "Sure." You continue, your voice low with need. "How do you want to do this?"

    "Just like this." She wraps her legs around your thighs, and her hands find their way behind your neck, trapping you on top of her. "This is perfect." She coos.

    You nod, and with easy, almost natural movements, you lower your hips and enter her once more. The moan that leaves Saerom is much softer, as if she is savoring the feel of you inside her properly for the first time. Your forehead presses against hers, watching her expressions as you smoothly slide in and out of her.

    "Wow you're beautiful." Saerom's eyes positively light up at your sudden compliment.

    "Thanks, you're not so bad yourself." She pulls you down to her, letting you feel every inch of her trembling body under you. No more words are needed, the two of you moving in a slow rhythm, her hips mirroring your movement, rocking up against you when you sink into her. All that's left are her melodic moans flowing into your ear.

    Saerom fits you tightly like a glove, far too well even, and the tell-tale tingle in your core signals the impending end of your compatibility test. She is similarly close, her movements beginning to decouple from yours - more rushed, more needy. You wince as she digs her nails into your back, her entire body clenching and writhing around you, the glove now compressing around your shaft, hot and wet.

    "You promised..." She manages between gasps of pleasure as you drive into her harder and faster.

    "What?"

    "You promised to fill me up really nice." The gasps are higher in pitch now. Her voice is shaky, right on the verge of breaking. You feel your senses begin to go numb with pleasure - "I-I need you to cum with me okay? O-oh god I'm so close!" Your mind goes blank, her words barely registering in your head. Your bodies function on their own primal accord, the dance vigorous, intense, and heated, until you both dissolve in pleasure.

    "Fuck!" With the same scream the two of you erupt in simultaneous climax, her silky walls contracting around you erratically, struggling to contain your throbbing shaft as you push against and into her. You send bursts of your seed deep in her, mixing with her slick fluids. The rest of your body ceases to function and you melt into Saerom's limp embrace, the two of you completely drained from the experience. The breathing under the covers is hot and heavy, as if both of you have just run a race. You watch her blissful expression, her eyes still closed, whimpers of joy still leaving her lips, curled in a small grin. When she finally opens them, she finds your staring right back at her.

    "Hi..." She manages once more with a dazzling smile.

    "Hey." The kiss you share afterwards tells you both everything you need to know about compatibility.

    As you smile at each other and cuddle under the covers, a muffled doorbell manages to make its way through the thick blankets. Saerom's eyes widen for a moment before she kisses you again.

    "Oh. Be right back." She gets out from under the covers and puts on her t-shirt. You rest for a moment before putting on your boxers and following her out.

    "Unnie, sorry I'm late!" A voice carries through the entrance. The voice carries on in outrage. "Did you start without me?!" You round the corner - Saerom stands in the doorway, and you can't make out who she's talking to.

    "N-No!" Comes Saerom’s abashed reply.

    "I can see his cum still dripping from you!" Sure enough Saerom's thighs are still shining with the messy mixture of cum and juice, evidence of what the two of you "started" earlier.

    "Who's that?" You call out, and Saerom quickly pulls you over, bringing you face-to-face with another stunning woman. A daring stunning woman, she gets close to you in an instant.

    "Hi there!" Her fingers climb up your chest before it drops to your crotch, rubbing you through your boxers. "I hope you didn't dump everything inside of her." She brushes past you and into Saerom's bedroom. "I'll get ready unnie!"

    Somehow shocked more by her actions than her looks, you turn to Saerom. "What was that?" She leans into your ear, her voice seductive, the shy, under-the-covers Saerom gone for now.

    "This is the rideshare part of the app..." She leads you back to the bedroom, where you find her friend down to her underwear, her hands just about to undo her bra.

    "Oh, did you want to strip me?" The friend surprises you with her forwardness and you struggle to keep your eyes off the bombshell, but not before Saerom drops the real bombshell on you.


    "And you're the ride."

    Author's note

    I wrote this solely because of the “rideshare” pun, and Fromis is probably the best “app name” of the groups I can think of. Of course I’ve wanted to write for Saerom too, there’s so many good smuts for her so I’ve put it off for so long. I was initially planning to make this whole thing a threesome, but I wanted Saerom to get her own chapter, so the threesome will come later! I have someone in mind but I’ve left it open for now. After the threesome I might make this a universe/series, where you use the Fromis app to have sex with different idols. After all, it is From Introductions to Sex, perfect for one-shots lol Thank you for reading!
