• Cuddling – Hyunsuk loves cuddling. He’ll pull you onto the couch, wrap you in a blanket burrito, and insist you stay there while he rubs your back or plays with your hair.
• Hype Man – Anytime you get dressed, he hypes you like you’re walking the MET Gala carpet. “Damn, baby. You’re not leaving the house looking like that unless I’m coming too.”
• Late-night Talks – He’s a night owl and loves lying in bed talking about random things: music, dreams, childhood stories. You’ll end up laughing at 2 AM or whispering sweet nothings until you fall asleep on his chest.
• Big on PDA – Hyunsuk loves holding your hand, back hugs in public, and quick forehead kisses when you’re not expecting it. It’s his way of grounding himself and showing you off at the same time.
• Protective – He’s chill, but if someone so much as looks at you the wrong way, he’s giving them the Hyunsuk Glare. He doesn’t always speak on it, but his body language is loud.
• Creative Dates – He’s always planning cute, unconventional dates: late-night walks with convenience store snacks, karaoke battles at home, or making a song together in his studio.
• Secretly Sentimental – He keeps all your notes, ticket stubs, even your doodles in a little box. He won’t admit it unless you catch him staring at it with a soft smile.
• Acts Tough, Melts Instantly – He might play it cool, but one pout from you and he’s instantly giving in, muttering “You’re lucky I’m obsessed with you.”
NSFW
• Dominance – Hyunsuk doesn’t yell—he commands. A firm grip under your chin, tilting your head up as he murmurs, “Strip. Now.” He watches you undress with that calm, dark gaze, cock already half-hard in his sweats, knowing you’ll obey without hesitation.
• Praise Kink – “Just like that, baby—fuck, you feel so good,” he groans, hips snapping up into you while you ride him slow and deep. He grabs your ass, helping you bounce faster, feeding off the way you moan when he says, “You take me so well, don’t you? My perfect fucktoy.”
• Biting Habit – Your thighs tremble from overstimulation, but he doesn’t stop. He kisses up your inner thigh, then sinks his teeth in—hard enough to make you gasp. “You’ll feel that tomorrow,” he grins, tongue flicking over the bruise he just left before diving back between your legs.
• Mirror Play – Bent over in front of the mirror, eyes glassy, mouth open—he loves watching you fall apart. One hand fisted in your hair, the other gripping your hip as he thrusts into you, making you watch yourself break. “Look how fucked out you are. That’s mine.”
• Whispered Filth – Hyunsuk leans in, breath hot against your ear. “You love being full of my cock, don’t you?” he growls, dragging his tongue along your jaw. “Such a pretty little slut—say it. Say you need me deeper.” And you do. Every time.
• Orgasm Control – He fingers you for what feels like hours—stopping right before you come. Again. And again. “Don’t cum until I say so,” he warns, voice dangerously low. When you finally do, it’s messy, legs shaking uncontrollably as he watches you fall apart with a smirk.
• Aftercare King – He fucks you into the mattress, raw and desperate—but after? He cleans you up gently, kisses the bite marks he left, holds you so close you melt. “Did I go too far, baby?” he whispers, pressing kisses to your temple. “You were so good for me.”
• Into Lingerie (On You) – He groans the moment he sees you in that sheer set, dick already hard against his zipper. He doesn’t even take it off right away—just pushes it aside and fucks you in it, muttering “This is mine. All fucking mine.” as the lace tears under his grip.
• Lap Fixation – You’re a moaning mess in his lap, hands gripping his shoulders as he thrusts up into you from below. One hand on your throat, the other teasing your clit. “Ride me, baby. Just like that. Show me how bad you need it.” His voice is sweet, but his hips say otherwise.
• Slow and Deep – There’s something about the way he drags it out—slow, relentless strokes that make you sob into the pillow. “Feel that? That’s how deep I go. No one else gets you like this.” He holds your wrists down and fucks you so slow it drives you insane. And he loves it.

PROMPT LIST
MASTERLIST
You loved getting to watch Haruto on stage. You could tell he loves what he does with the other members of Treasure. You especially loved watching him when they were touring in Japan. Something about being in his home country sets him off like no other. He’s even more energetic than usual and also more playful on stage. Wetting everyone and himself with the water, pulling up his shirt, sticking out his tongue, he was driving you wild. You couldn’t wait for the show to be over because watching him out there was getting you so hot and bothered. As the final notes of the encore faded and the lights dimmed, your heart raced with anticipation. You made your way backstage, flashing your VIP pass to security. The corridors buzzed with post-show energy, but you had eyes for only one person. You found Haruto in the dressing room, still flushed and breathless from the performance. His damp shirt clung to his body, outlining every curve of muscle. When he saw you, his eyes lit up with that mischievous spark you adored.
"Did you enjoy the show?" he asked, a knowing smirk playing on his lips. You crossed the room in three quick strides, pressing him against the wall.
"You have no idea," you breathed, before capturing his mouth in a searing kiss. Haruto responded eagerly, his hands roaming your body. He pulls away and before you can ask what’s wrong he is saying, “Maybe we should take this somewhere a little more secluded before all the rest of the guys come in?”
“I don’t know if I can wait much longer,” you say, “You think they wouldn’t like the free show?”
“Oh really,” Haruto questions. Then he’s turning you around in his arms one hand gently squeezing your throat and the other wrapped around your waist as he continues, “You such a filthy slut that you want me to show all my group mates how good I fuck you?” Your breath catches in your throat at his words and his firm grip. The thrill of his dominance sends a shiver down your spine.
"Maybe I am," you whisper breathlessly, pressing back against him, "But only for you."
Haruto growls low in your ear, his hot breath fanning your neck, "Then let's give them something to remember." In one swift motion, he spins you around and lifts you onto the makeup counter. Cosmetics and hair products clatter to the floor as he positions himself between your legs. His lips crash into yours hungrily as his hands roam your body, leaving trails of fire in their wake. You moan into the kiss, wrapping your legs around his waist to pull him closer. Your fingers tangle in his sweat-dampened hair as his mouth moves to your neck, nipping and sucking at the sensitive skin. Just then the door opens and in walks the other two members of Treasure’s rap line. Hyunsuk and Yoshi stop in their tracks shocked at the sight in front of them. You are so immersed in the kiss with Haruto that you don’t even notice that they have come in until you hear the clicking of a lock and Yoshi clearing his throat. You freeze, your eyes widening as you see Hyunsuk and Yoshi standing there. Haruto turns his head, keeping you pressed against him. Instead of looking embarrassed, a wicked grin spreads across his face.
"Well, well," he says, voice low and husky, "Looks like we have an audience after all."
Hyunsuk raises an eyebrow, a smirk playing on his lips, "Don't let us interrupt," he says smoothly.
Yoshi's gaze rakes over you hungrily, "Mind if we watch," he asks. Your heart pounds wildly, a mix of nerves and excitement coursing through you. You look at Haruto questioningly. He meets your eyes, silently asking for permission. The heat in his gaze makes you shiver with desire.
"Only if you want them to," Haruto says, “Although, it was your idea to give a show. Don’t tell me you’re shy now.” You bite your lip, torn between embarrassment and arousal. The idea of being watched sends a thrill through you.
Throwing caution to the wind, you pull Haruto close and whisper in his ear, "Show them how good you make me feel."
Haruto's eyes darken with lust. He turns to Hyunsuk and Yoshi, who are watching intently, "Take a seat, boys. Class is in session." Without further preamble, Haruto's hands slide under your shirt, pulling it up and off to expose your skin. His mouth latches onto your collarbone, sucking and biting as his fingers work at your bra clasp. You moan softly, hyper-aware of the eyes on you. Hyunsuk and Yoshi settle into chairs, their gazes hungry as they watch. You catch Yoshi adjusting himself. Haruto's skilled fingers make quick work of your bra, tossing it aside. His mouth trails lower, leaving a path of fiery kisses down to your breasts. You gasp as he takes a nipple between his lips, swirling his tongue around the sensitive bud. Your back arches, pressing yourself closer to him. You hear a low groan from across the room and glance over to see Yoshi palming himself through his pants. The sight sends another jolt of arousal through you. Haruto notices your distraction and nips at your breast, drawing your attention back to him.
"Eyes on me, baby," he murmurs against your skin, "They can look, but only I get to touch." His hands slide down your sides to your hips, fingers hooking into the waistband of your pants. He looks up at you, silently asking permission. You nod in agreement and he helps you off the counter so he can remove your pants.
“No panties,” Haruto asks, “You really were eager for my cock huh?”
You nod, a blush creeping across your cheeks.
"I couldn't wait," you admit breathlessly. Haruto's eyes darken with lust.
"Such a naughty girl," he growls, lifting you back onto the counter, "I think you deserve a reward for being so prepared." Without warning, he drops to his knees in front of you. His hot breath ghosts over your sensitive flesh, making you shiver in anticipation. He looks up at you through his lashes, maintaining eye contact as he slowly drags his tongue along your slit. You cry out at the sensation, your hands flying to tangle in his hair. Haruto hums in approval, the vibrations sending pleasure coursing through you. He laps at you eagerly, alternating between broad strokes of his tongue and focused attention. Your head falls back against the mirror as Haruto's skilled tongue works you into a frenzy. He sucks your clit into his mouth, flicking it with the tip of his tongue. Your thighs tremble around his head as pleasure builds within you.
"Oh god, Haruto," you moan, tugging at his hair. He responds by sliding two fingers inside you, curling them to hit that perfect spot. The dual stimulation has you teetering on the edge. You're vaguely aware of the sounds of heavy breathing and rustling fabric from across the room, but you can't bring yourself to look. All of your focus is on Haruto and the incredible things he's doing to your body.
"That's it, baby," Haruto murmurs against you, "Let go for me. Show them how good I make you feel." You moan louder, past caring about who might hear. Haruto increases his pace, his fingers pumping in and out as his tongue flicks rapidly over your sensitive bud. The coil of pleasure in your core winds tighter and tighter until it finally snaps. You come with a cry of Haruto's name, your body shaking as waves of pleasure crash over you.
“Stay with me baby,” Haruto says, “I am not done with you yet.”
You're still trembling from your intense orgasm when Haruto stands, wiping his mouth with the back of his hand. His eyes are dark with desire as he looks you over hungrily. Without breaking eye contact, he slowly pulls his shirt over his head, revealing his toned abs and chest. Your mouth goes dry at the sight.
"See something you like," he teases, his hands moving to the waistband of his pants. You nod eagerly, licking your lips in anticipation. Haruto smirks, taking his time as he unbuttons his pants and slides them down his legs along with his underwear. His erection springs free, hard, and ready. You reach for him, but Haruto catches your wrists, pinning them above your head.
"Ah ah," he chides playfully, "I'm in charge here, remember?" You whimper with need as Haruto holds you in place, his body tantalizingly close but not touching.
He leans in, his lips brushing your ear as he whispers, "Tell me what you want, baby. Let them hear how desperate you are for me." Your face flushes hot with embarrassment and arousal. You're acutely aware of Hyunsuk and Yoshi watching intently, but Haruto's proximity is intoxicating.
"Please," you breathe, "I need you inside me."
"Louder," Haruto commands, nipping at your earlobe.
"Please fuck me, Haruto," you moan, louder this time, "I need your cock so bad." Haruto grins wickedly.
"Good girl," he purrs, releasing your wrists. In one fluid motion, he lifts you up off the counter and has you bent over the armrest of the couch opposite where Yoshi and Hyunsuk are sitting. He has your head pushed down facing them and this is the first good look at them you’ve gotten since they walked in. Your eyes lock with Yoshi's, his gaze intense and hungry. He's leaning back in his chair, one hand gripping the armrest while the other moves rhythmically along his now-freed cock. Beside him, Hyunsuk is also stroking himself slowly as he watches. The sight sends another jolt of arousal through you. Who knew that the entire rap line was so well-endowed. You make a mental note to ask Haruto about them joining you two some time. Haruto's hands grip your hips firmly as he positions himself behind you. You feel the blunt head of his cock pressing against your entrance, teasing but not entering, and that brings you back into the moment. You whimper, trying to push back against him, but his grip holds you in place.
"Tell them how badly you want it," Haruto commands, his voice husky with desire.
"Please," you moan, your eyes still locked on Yoshi's, "I need it so bad. I need you to fuck me, Haruto." In one smooth thrust, Haruto enters you fully, stretching and filling you deliciously. You cry out in pleasure, your fingers digging into the couch cushions. Haruto sets a punishing pace, his hips snapping against yours with each thrust.
"That's it, baby," Haruto growls, his fingers digging into your hips, "Take it all." You moan wantonly, overwhelmed by the sensations. Haruto's cock hits all the right spots inside you, sending waves of pleasure through your body with each thrust. The sound of skin slapping against skin fills the room, punctuated by your cries and Haruto's low grunts. Your eyes flutter open, meeting Yoshi's intense gaze once more. His hand moves faster on his cock as he watches Haruto pound into you. Beside him, Hyunsuk's breathing has grown ragged, his own movements becoming more erratic.
"Look at them," Haruto commands, gripping your hair and pulling your head up, "See how much they're enjoying the show? How badly they wish they were in my place?" You whimper as this new angle has Haruto hitting all the right places inside you. Your eyes dart between Yoshi and Hyunsuk, taking in their flushed faces and lust-filled gazes. The sight of them pleasuring themselves while watching you and Haruto only heightens your arousal. Haruto's thrusts become even more forceful, driving you closer to the edge.
"Tell them," Haruto demands, his voice strained with effort, "Tell them how good it feels."
"So good," you moan, your voice breathy and desperate, "Haruto feels so amazing inside me. I love his cock so much." Haruto rewards your obedience by reaching around to rub tight circles on your clit. The added stimulation has you seeing stars, your second orgasm rapidly approaching.
"That's it, baby," Haruto encourages, "Come for me. Let them see how well I can please you." The combination of Haruto's relentless thrusts, his skilled fingers on your clit, and the intense gazes of Yoshi and Hyunsuk push you over the edge. Your orgasm crashes over you in powerful waves, your inner walls clenching around Haruto's cock as you cry out his name. Your vision blurs as pleasure courses through your body, leaving you trembling and gasping for air. Haruto's rhythm falters as your climax triggers his own. With a deep groan, he buries himself to the hilt inside you, his cock pulsing as he finds his release. You feel the warmth of his seed filling you, prolonging your own pleasure. As you both come down from your highs, you become aware of muffled grunts from across the room. You look up to see Yoshi and Hyunsuk reaching their own climax. As you watch Yoshi and Hyunsuk come undone, a wave of satisfaction washes over you. Haruto gently pulls out and helps you stand, wrapping his arms around you from behind. You lean back against his chest, still catching your breath.
"Well," Haruto says with a smirk, addressing Yoshi and Hyunsuk, "I hope you enjoyed the show."
Hyunsuk chuckles, cleaning himself up with some tissues, "That was quite the performance," he says appreciatively.
Yoshi nods in agreement, his eyes still dark with lingering desire, "You two are something else," he adds.
Haruto's hands caress your sides possessively. "This one is all mine," he warns playfully, "But maybe I will let you borrow her one day. I like to watch too."
“Haruto,” you cry out in embarrassment. Although, you aren’t entirely opposed to the idea. Haruto chuckles at your reaction, placing a gentle kiss on your neck.
"Don't worry, baby. I'm just teasing," he murmurs against your skin, "Unless..." He trails off, leaving the implication hanging in the air. You feel a thrill of excitement at the possibility, but decide to play coy.
"Maybe we should discuss that in private," you whisper, turning your head to nip at his earlobe. Haruto groans softly, his grip on you tightening.
"You're insatiable," he growls playfully. Across the room, Yoshi and Hyunsuk exchange amused glances.
"I think that's our cue to leave," Hyunsuk says, standing up and adjusting his clothes. Yoshi follows suit, his eyes lingering on you and Haruto for a moment longer. After they leave you and Haruto take your time redressing. Then, also walk out of the dressing room to head to the vans that will take you to the hotel. You are definitely going to talk later and you might have to invite some people over to your room tonight.
