    "Hey oppa!" You look up to have your jaw drop down.

     

    "Yujin?" She looked stunning, dressed in a tight-fitting white shirt with the top button loosened, similar to the tie around her neck. She completes the look with a dark green plaid skirt and long white socks, making her legs seem even longer than usual.

     

    "Did you enjoy my performance?" You watched her dance on stage, but nothing beats Yujin sauntering into your apartment and sitting in your lap.

     

    "Y-yeah, mm!" Your eyes fly open in surprise before fluttering shut when she captures your lips, kissing you hungrily. She breaks the kiss, cheeks pink.

     

    "I danced it for you, you're my hype boy, you know that?" Yujin is passionate, a hand on your chin as she brings you in for another kiss. Gentle is your caress across her chin, and you can feel her warm breath over your fingertips as you brush her lips, smearing her lipstick slightly. But she didn't mind it at all when you pulled her closer to you.

     

    "Sure, I'll be your hype boy." Inevitably your hands roam her body, making her coo and gasp as you "hype" Yujin up, herself starting to play with your t-shirt. As your hands go to her tie, you can't help but notice its familiarity.

     

    "Is this my tie?"

     

    "Yeah, I wanted you to be on stage with me, so I borrowed it."

     

    "Borrowed, or took?" you remark, pushing past Yujin's offense to kiss the open collar of her shirt. Her throat vibrates with a moan as you lay open kisses on her chest, and her tummy twitches as you start lifting the shirt from below.

     

    "B-Borrowed?" You look up to see Yujin pouting cutely, even as she subtly grinds herself in your lap. Her fingers trace the back of your neck, making you hiss in pleasure—she knows what you like. You loosen the tie, holding it in your hands.

     

    "Oh, yeah, I definitely remember letting you borrow it."

     

    "Right? See, I borrowed it." Through her long black hair you can still see her gleaming cheeky smile, and you brush it back with a careless hand. She really is pretty, and the smile disappears into a needy look and a whine when you pull her in for another kiss. Your hand dances under her tight shirt, gently rubbing broad circles on her back as you hugged her, and Yujin melts in your lap—you also know what she likes. 

     

    With a wordless look your hands go down instead of up, squeezing her thighs as you sneak up her skirt. Yujin is similarly working on your shorts, pulling them down far enough for what the two of you needed. You travel further up her legs, quickly pulling off what you find there too—Yujin squirms in your lap, managing to slide it off one long leg, then the other, before kicking it away.

     

    "Ahh, you're driving me crazy," she whimpers. The two of you go hi-i-i-i-igh as Yujin sinks herself down on you. She's extra sensitive, her expressions super-animated—her small yelps and squeals fill the room as she drives herself down on you to higher pleasures. You're just a passenger on her ride, and you bury your face wherever you can to muffle your moans—in her neck, into her chest, and finally against her lips.

     

    "Oppa— Mmmph!" Yujin almost bangs her teeth against yours as oxytocin takes the two of you to a sky-high chemical high. Your seed rushes into her uncontrollably—maybe this would be the one. It feels like a dream to have Yujin in your arms, one you would forget if you open your eyes. But no, your eyes are open, and she's looking right back at you.

     

    "I love you." "I love you." The words leave your lips simultaneously, and breathless laughter fills the room at the impromptu mimicry. She half yelps and half laughs when you stand up, leaving her clinging around your neck as you take her to the bedroom.

     

    "Oppa?" Yujin feels you against her and blushes, and she watches you shed your clothes before letting you take off her own. As your bodies tangle together, her fingers intertwine with yours, holding you close as you moan into her neck.

     

    "You're my hype girl too."

    Author's note
