    "Hey Ting," you call out as you reach the rooftop.

     

    "Oh oppa, come quickly!" she waves you over, her eyes glued to the night sky. "It's going to start soon!"

     

    "What is?"

     

    "The shooting stars!"

     

    Can we even see them here? you ponder to yourself—you were still in the city after all. You join Xiaoting at the table, and she pulls your arm around her, resting her head on your shoulder. You kiss the crown of her fiery red hair.

     

    "Are you cold?"

     

    "Not if you're here with me," you murmur in her ear, hugging her from behind, hands comfortably around her waist. You sigh into her shoulder, and Xiaoting sighs contentedly and leans back, melting in your embrace. The two of you quietly look at the night sky, waiting for the first streaks of starlight.

     

    A few minutes later though, you catch the first rays of manlight—an apartment across from Xiaoting's balcony. Xiaoting perks up at the familiar silhouette.

     

    "Oh, it's Yujin!" She slips one hand out of your hug to wave, and you join her, waving at Yujin to catch her attention. When Yujin waves back, Xiaoting mimes and points a hand upwards to the sky, and Yujin nods—she is there to watch the shooting stars too. Xiaoting tries to wave her over, to get Yujin to join the two of you, but she declines, her hands doing a kissing motion before doing a large “X”, indicating she didn't want to third wheel the two of you. The two of you blush, but Xiaoting cranes her neck up at you, and you take the chance to do exactly what Yujin motioned, leaning down to peck her.

     

    "Yaaaah Yujin's watching!"


     

    Aww that's so cute! Yujin squeals internally, happy for Xiaoting and her boyfriend. She waggles her eyebrows suggestively, puckering her lips and mocking them, and they blush before settling back to looking up at the night sky. Yujin joins them in looking up at the night sky, wishing her boyfriend is here with her too, but alas, he has to work late tonight. After a while she sighs and checks her phone—15 minutes past the supposed time the shooting stars should have appeared. Maybe it’s too bright in the city, maybe she should just turn in.

     

    She starts to turn away, but movement on Xiaoting's balcony causes her to stop. The candlelight is dim, but she can make out the form of the two of them, well, making out. Xiaoting's hand is on his cheek, and her exposed neck is stretching, craning to reach up to kiss him. His hand strokes her face tenderly before moving down to cover her vulnerability. It is not clear at night, but the two of them seem to be moving as one, passionately kissing under the night sky.

     

    "Ting..." You break the kiss and groan. You lean down to kiss Xiaoting again, but you are stopped by her grabbing your hand and resting it on her hips. Not just anywhere on her hips though—you are right at the waistband of her jeans, and they are loose.

     

    "Xiaoting?" you ask quietly, even as your fingers slip between skin and fabric, confirming that she has loosened her jeans. Soon your fingers are between skin and air, her jeans now down to knee-level if anyone else was watching.

     

    "I want it," she whines. This time your fingers are trapped between skin and thinner fabric, and you kiss her hungrily as you press two fingers against her wetness.

     

    "I thought you said Yujin was watching?" you murmur.

     

    "I want it now! B-besides, look, the light's off now, she's probably gone." Xiaoting makes her case, not that you needed any convincing. Gently you part her lips, slowly you rub her walls, and oh so delicately she moans into your kiss, her hips starting to grind against you. The flickers of candlelight splash on the two of you, just like Xiaoting is beginning to do so in your palm—she is wetter than usual, the romantic yet thrilling atmosphere really getting her into the mood.

     

    The hand on your neck is gentle, but that quickly changes as Xiaoting begins pushing her hips against your hand, urging you to push into her, to do more than rub her walls, to fingerfuck her. You curl your fingers, and the empty side of your neck is now marked with dark hickeys as she sucks your neck to muffle her whimpers.

     

    "Just a little more," she gasps, and the hand around your neck pulls you more urgently, her nails starting to dig into you. "Almost, almost, almost!" As you continue to finger Xiaoting her free hand grabs your arm, and with a sharp pull from her your palm grinds against her engorged clit.

     

    With a squeal and a bump that almost knocks the candle over you trigger Xiaoting's wet orgasm, a warm wave of juice leaking around your fingers and on to your palm. With your hand still wrapped around her waist you feel the flex and quake of Xiaoting's abs, twitching in time to her walls trying to suck your fingers deeper into her. Eventually she regains control over her body, and Xiaoting breathes heavily in your embrace.

     

    "Oh, oh, oh..." Her tightly shut eyes open up, looking at you brighter than the stars in the sky. "Thanks babe."

     

    "Of course, shall we go back in?" your voice is laced with lust—you needed to have her soon.

     

    "Not yet! It's your turn." She teases, and deftly she reaches for you, undoing your jeans with surprising speed. And just when you expect her to stroke you off, you are surprised further when she leans back onto you, tiptoeing and trying to find the right connection.

     

    "Xiaoting!" You groan, and both of you are looking up at the stars, head snapped back as her warmth swallows you up. "What are you doing?"

     

    "I-I wanted to do it here... Can we?" You could not say no, not with her cute pout and her tightly wrapped around you. You nod, and you decide to test a theory.

     

    "If you want," you whisper in her ear, making sure she's facing Yujin's window. "Let's make sure Yujin can have a good look?"

     

    "Noooo don't!" Xiaoting whines, but the sudden constriction around your shaft reveals the truth. That's new, you think between waves of pleasure, slowly starting to move in and out of her surreptitiously.

     

    "When did you become so daring darling?"

     

    "No it's just... nnngh!" The night sky is clear, but a lightning bolt shoots straight up her spine as you find the perfect angle for her. "J-just thrilling!"

     

    "I don't think her curtains are all the way closed, do you think she's peeking right now, stealing a look? Do you think she's horny watching you, watching us?"

     

    "Don't say that!" Xiaoting gasps—you're only slowly pumping into her, your movements not noticeable for anyone actually looking, but to the amped up Xiaoting you might as well be railing her right now, the pleasure starting to take control of her body again. She's way tighter than usual, and your head drags all over her sweet spots easily. She looks up at you pleadingly.

     

    "I'm going to cum again!"

     

    "Wait!" You pause, and the whine Xiaoting releases is downright heavenly. You put your body weight on her, leaning over and blowing the candle out, plunging the two of you into darkness. "Only I get to see you cum, not Yujin, not anyone else, now cum for me!"

     

    "B-babe no, wait, mmmph!" Your slow and hard thrusts push her way over the edge, and with your thumb on her clit she has to kiss you to muffle her screams. Xiaoting squirts around you, your thighs suddenly wet and her slick leaking out of your connection. Her legs sag and weaken, and you pressing her against the table is the only thing still keeping Xiaoting standing.

     

    "You look beautiful." You swear Xiaoting is able to glow in the dark as you watch the blush on her cheeks slowly fade. Weakly she smiles and reaches behind, grabbing your back and pulling you towards her.

     

    "Cum in me. Only I get to feel you cum, no one else."

     

    Throwing caution to the wind you make Xiaoting whimper with your quick thrusts, praying that the cloudless night can provide cover. There may have been shooting stars overhead, but you don't care—you are shooting thick, white, scalding stars into Xiaoting, making them burst as you go supernova inside her. Over and over you pulse, spraying stardust into the center of your universe—Xiaoting grabs your arm tightly, squeezing you with every shot of warmth in her. You struggle to stay on your feet, but the two of you are able to keep each other standing, using each other and the table for support. Tiredly Xiaoting turns to look at your, her eyes shining with love.

     

    "Kiss me."

     

    Mwah.

     

    "No!" Yujin gasps when Xiaoting's boyfriend blows out the candle. She was sure they were fucking, right there out in the open. She had seen Xiaoting's eyes shut tightly, mouth wordlessly opening and closing, body seized with pleasure. And then Yujin had seen them both look up, as if to watch the shooting stars, but no, their slow movements were rhythmic and in sync, doing the basest of dances. It was fucking hot to watch, and Yujin couldn't tear her eyes from the couple.

     

    Yet the sudden darkness denied Yujin relief, and she looked at her fingers—they were sticky, connected with multiple strands of slick. She needed something, her own fingers would not be satisfying enough, she needed someone...


     

    You hurry to Yujin's apartment, her message worrying you.

     

    Hey can you come over?

     

    Is something wrong?

     

    I need you here, please

     

    After begging out of work, much to the grumbling of your coworkers, you rush to Yujin's apartment.

     

    "Hey Yujin—whoa!" Yujin flings herself at you, and you are deathly worried for her—she is warm in your arms and her face is red. Her typical happy-to-see-you expression is gone, replaced with one of urgency. You reach out, pressing the back of your hand to her forehead.

     

    "Are you okay? Do you have a fever?"

     

    "N-no! Please, I need you." Her hands are tugging on your clothes, and you hold her still, hugging her and bringing her to the couch.

     

    "Slow down, what do you need me to do? How do you feel?" She retains her hold on your shirt, and the reason why is made very apparent when she whines.

     

    "I need to have sex with you, right now. Touch me!" Yujin pulls your hand between her legs and against her pajamas, and your reaction is immediate.

     

    "Y-you're soaked," you say hoarsely, your throat suddenly dry. "Did you eat something wrong? Were you drugged?!" You follow up in alarm, examining her to make sure she wasn't hurt.

     

    "No silly! I saw Xiaoting and her boyfriend on the balcony, they were watching the shooting stars. A-and then I think he fingered her, she came, and then they were having sex right there, and then he blew out the candle! I... happened to see them," Yujin finishes lamely, despite having outed herself as having watched the entire time.

     

    "So you saw them. And now?" you ask, laying her on the sofa, cushioning her head with your hand.

     

    "I need you honey, please!" You place your hand on her flat belly, and Yujin immediately arches her back, urging your hand to dive below the waistline of her pajamas—good lord she was needy. Her eyes are wild with lust, pleading with you to get down there and do something, anything to her. You slide past her bellybutton, down past her hipline, and her legs are quivering with anticipation. The closer you get to her wetness, no, fountain, the wider she spreads her thighs, only restrained by her pajama pants.

     

    "Is this what you want?" You don't give Yujin a chance to answer, and you plunge two digits into her right away.

     

    "Oh fuck yes..." Your fingers are thicker than hers, and Yujin lets out a guttural groan of relief, orgasming on the spot. After watching Xiaoting and her boyfriend, Yujin's imagination ran wild, wild enough to edge herself just on thought alone, making her filthy fuel leak all over before you plugged her up. And now? Now that that's out of the way, Yujin wanted you to do everything she had imagined to her, starting with your fingers.

     

    "C-come here." Shakily she gets to her feet, leaving the wet puddle she calls her pants behind, and you follow her to the window. You're not sure why she's facing the window with the curtain's drawn, but you rarely see Yujin this hungry, and you were eager to please. "Hold me!" Yujin does your work for you, grabbing your hands and having you wrap your arms around her just the way she wanted it. One of your hands lands right back between her legs, and you get the hint, slowly rubbing her clit as she reaches behind to touch you, running her hands along your body.

     

    "Yes, just like that, just like they did it..."

     

    "Just like they did it? You were watching weren't you?"

     

    "Yes, it was so hot!"

     

    "Think back to it, did he touch her... here?" you ask, moving your hand over her still clothed breast, gently grabbing and squeezing her.

     

    "Mmm yes, just like that."

     

    "And then what happened next?"

     

    "And then she came, I think— Oh, oh yes!" Hurriedly Yujin muffles a loud moan into your arm, seeming to have relived the memories into a quick orgasm. She freezes in pleasure, and a small splash of juice hits the floor before she goes weak in your arms. You were stunned but equally turned on at how easily she came, and you hastily take off your pants while still holding her up.

     

    "What happened next? Do you think they fucked?" Even as you ask her you are already lining yourself up with Yujin.

     

    "I don't—nngh honey! Yes, yes they definitely did!" Yujin realizes the answer midway as her head snaps back in pleasure when you push into her. "They definitely did, go slowly!" After two orgasms Yujin's nerves were burning brighter than any star, so you kiss her passionately, keeping her flames burning, but not enough to incinerate.

     

    "You're so tight carrot..." you murmur in her ear, using your pet name for Yujin. She really is tight, and you moan softly as your head drags over her walls, almost struggling to pull out as she tries her best to suck you in. "I just want to eat you up, what came over you?"

     

    "I don't know, it was just so hot, eat me up baby, I can't take it anymore but I think I'm cumming again!" Yujin's whisper rises into a squeal as you rub circles around her clit. You press down and rub it firmly as you capture her lips, and the tongue you stick into her blocks her loud scream as she climaxes wetly around you, her entire body shuddering in ecstasy. Yujin has a death grip on your arm, but you power through it and her orgasm, continuing to tease her pleasure button while pumping into her.

     

    You pull back a little, Yujin's tongue twisting around yours making it almost unbearable with how close you were.

     

    "Where did he finish?"

     

    "I-I don't know, he blew out the candle, I only saw shapes moving—" But Yujin's imagination and desires paints the entire scene in high resolution for her. "But I think he bent her over and pounded her silly, there's no way he pulls out, there's no way Xiaoting lets him pull out! I want you to do that too honey!"

     

    "Fuck Yujin that's too risky!"

     

    "I need you to do it! I want some honey from my honey, we'll make some cute little bunnies together and— Ah!" With a low moan you pin Yujin against the curtained window, frantically humping her like an animal. Your fingers interlace with hers, and together you threaten to tear holes in the sheer curtain. You plunge into her hot, wet, tight darkness one more time, and thick white honey floods Yujin, the sticky substance coating her walls and then some as you fill her honeypot.

     

    There is no doubt Yujin is well-stocked by the time you finish, her legs quivering as large globs of slick and cum drip out of her, the two of you utterly satiated—you thoroughly enjoyed your carrot, and Yujin thoroughly enjoyed her honey.

     

    Yujin clings on to you like a koala, and with what strength you have you carry her to the shower, getting clean together before tucking into bed next to her.

     

    "Remind me to thank Xiaoting," you mumble into Yujin's hair as she nuzzles your neck.

     

    "Shut up, don't let her know!" You can feel the heat radiating from her cheeks.

     

    "Oh, now you're embarrassed about spying on our friends?"

     

    "It's not spying! They were doing it in public, I just happened to be watching!"

     

    "That CLC spy concept really fits you now."

     

    "Whatever, I'm going to sleep!"

     

    "Good night, love you."

     

    "Love you too oppa."

     

    The next morning Yujin pouts as you bid her good bye—you'd have to work extra late today because of her "emergency" yesterday. It was worth it though—both of you woke up sore but refreshed after the good night of sleep. Alone in the apartment she hums and checks her phone, blushing when she sees a message from Xiaoting.

     

    Unnie did you enjoy the shooting stars?

     

    Yes, I did, I hope you two enjoyed it too!

     

    It is Xiaoting's turn to blush from across the building.

     

    Yes, we did. But you know unnie... you didn't turn the lights off yesterday before you went to sleep

     

    Did I not? I thought I did

     

    Oh, maybe I was mistaken, oppa came back earlier than usual? I thought I saw a light

     

    Oh right, he came back early yesterday

     

    Ah, I see ;)

     

    Why?

     

    Nothing! Unnie, can you tell me what curtains you use? They look very nice last time I came over

     

    Oh, the sheer curtains? Yeah they let light in nicely in the morning, I'll send you a link!

     

    Still in bed and wonderfully sore, Xiaoting fires off a quick “thanks” before giggling a little to herself. She snuggles into her boyfriend's arms as they wrap around her.

     

    "What did she say?"

     

    "She said she'll send me the link."

     

    "Great, remind me to thank Yujin later."

     

    "Heh shut up!"

     

    Oh, if Yujin only knew why they wanted those curtains.


    A/N: This started off just as a BFH for those Xiaoting candlelit photos, then became a lot more. It became a very perverted Hitchcock Rear Window thing, hence the title. I also wanted to write Yujin in those pajamas for the longest time, but that became the Seasons of Love fic instead lol. So yeah, ideas warp and change all the time in my head heh. Also trying something new with two different “you” perspectives. Rather than one OC it is two different OCs in one smut, hope it works. Thanks for reading!
