a/n: first fic of 2026!!!
Your best friend and roommate Seongwha was due home from work at any second, yet you still scrolled various spicy Tumblr tags on the living room couch anyway. What were you trying to find? Hopefully something that would help you scratch the itch you had.
A few days ago you dreamt you watched a gorgeous man stoke himself until he came all over his stomach and thighs and you couldn't get that image out of your mind. It replayed like a gif nonstop in your mind, especially at night when you were alone. Just like tonight.
"Still nothing..." You groan to yourself and rub your temples. Why did nothing else compare to that dream you had? Suddenly, the door flew open and a sweaty, frustrated Seonghwa entered the apartment. You quickly hid your phone under the pillow and tried poorly to play it cool.
"Seonghwa! Hey!" You exclaim a little too cheerfully, but Seonghwa is too annoyed to notice. "Rough day at work?" You ask him concerned, forgetting about your less-than-innocent activities from earlier. He groans. "Yeah, I'm just glad to be home." He gave you a weak smile. "I'll go heat up some leftovers. How does that sound?" You offer.
"Perfect. Thank you Y/n." He takes his shoes off and tosses himself onto the couch, resting one hand under his head, closing his eyes. With your back to him in the kitchen, he squirms on the lumpy couch, trying to get comfortable. Was this couch always so hard? He turns over and kneads the cushions, when he finds the source of his discomfort tucked away under the pillow.
It was your phone. He tilted his head and picked it up, the phone screen waking up with his touch. On the screen, he was met with your search: "Men touching themselves", "Men masturbation audio", and various other combinations of words all meaning the same thing. He bit his lip to suppress his laugh. He scrolled a bit, looking through all the results from your search, now wide awake and in a very different mood than before. He didn't take you as the type to like that kind of stuff, especially the kind to enjoy it in the living room, but for some reason he was feeling kind of...jealous? Jealous at the idea that you were looking so diligently for something that he could do for you himself right at home.
Glancing over at you, still preoccupied with the food, he decided to have some fun and make his day better. "You know, this video isn't so bad, should I reblog it for you so you can watch it later?" He teased and you quickly turned to face him. Your face was pale as a ghost, your heart trembling, hoping you misheard him. "What did you just say?" You say weakly, hands shakily gripping the Tupperware. Seonghwa waves your phone at you and grins, the screen showing the explicit video he was talking about. "No!!" You shriek and run to him, throwing yourself on top of him to get your phone back. "Just leave it alone! It isn't what it looks like! I just clicked one of those weird ads, it's a virus I swear!!" The lame excuses spill out from your lips, but the way your face was colored bright red told Seonghwa the truth.
He looked up at you through his lashes with darkened eyes. His expression was lustful and sadistic, like a tiger playing with his pray before eating it. He's never seen you so vulnerable like this, and it made him even more excited than he already was. He carelessly tosses your phone behind him, instead, wrapping his arms around your waist and pressing you tightly against him.
"Was my baby feeling needy? Hmm?" He kept teasing you. You turn your head away from him stubbornly, refusing to meet his gaze. Your ears burned from hearing the new nickname he gave you. "My baby has such unique tastes." He doted on you, gripping your chin forcing you to look at him. "But she isn't very smart. Here she is, desperately searching for the perfect video of a man touching himself, yet she can see the real thing anytime she wants if she asks me. How silly is that?" His fingers wander from your chin down your neck, then to your shoulder with feather-like movements, stopping when he reaches the strap of your tank top.
Your brain is so clouded. His words are tempting and you do feel extremely needy. A single rational thought could not be found in your head. "I could ask you for that?" You barely manage to whisper to him shamefully. He tucks a strand of your hair behind your ear. "If you do it nicely, yes."
"Seonghwa, can you let me watch you jerk off? Please." The words burn on your tongue, what you're saying feels so wrong. But from the way he's looking at you, you said exactly the right words. "Of course you can." And just like that, Seonghwa pulls up a chair in front of the couch and strips completely before sitting on it. "Like this? Is this how you like it?" He asks casually and you sit up and grip the couch cushions below you harshly. Your gaze roams all over his sculpted body, now fully on display for you. "Yes that's really good." He chuckles at your praise. "Tell me what to do next, exactly how you want it."
You glance down at his member, and it's already getting hard just from you looking at it. "Okay, uhm...Can you spit in your hand and touch it like how you would if I wasn't here right now?" Your request goes straight to his dick and it twitches. You already feel the arousal and heat forming in your stomach and you hold a pillow tightly, unable to hide how much you were enjoying this. Seonghwa feels hot under your intense stare as he dips two fingers into his mouth, his tongue swirling around his them with loud slurping sounds.
You feel yourself breathing heavy just from that sight alone. You press your thighs together on the couch, which doesn't go unnoticed. Once he collects enough saliva, his hand slowly trails down to his member. He coats it thickly, his hand lazily brushing against it. "You know, when I found out you were wasting your time trying to look at other guys doing this, it pissed me off." He confessed as one hand caressed his balls, his other holding his legs open. "Why?" You asked, your voice trembling. His brow furrows and he hisses from the contact.
"Because I was jealous. I do this in my room most nights, just on the other side of your bedroom wall, you know? I try to be quiet, but when I can't, I think of you lying on your bed hearing me come undone." A moan slips out of his lips as he grips his base, squeezing it tightly. "And it feels so good. I hump into my mattress like a pathetic loser hoping you'll hear me. Isn't that sad? Yet here is my greedy baby looking up such filthy things. Ignoring me." His words get more frustrated as he finally strokes himself, tugging roughly. At this point, your eyes are wide, a few whines slipping out of you, as you feel the desire build up in you.
Just like if you were alone in your room, you bring the pillow down to your core and press it in between your legs to give yourself some pressure. Seonghwa smirks and licks his lips, feeling even better knowing the effect he's having on you. "But this? It's even better than I was imagining." He brings his resting hand to his tip, rubbing his thumb against it while the other moves along his shaft in a steady rhythm. The sound of his wet skin slapping against his hand is driving you crazy. Sweat coats his body, making it glisten, and his hair sticks to his face. You can tell he wants to keep staring at you, but the whole situation feels too good, it overwhelms all his senses, so he can't resist closing his eyes and throwing his head back.
Seonghwa's moans fill the room, soon mixing with yours as you watch him pleasure himself. Your eyes are glued to his form while your hands automatically rub the pillow harder against your clothed heat. But as you felt yourself reaching the edge, he stops. One of his hands wipes the sweat from his brow. His chest rises and falls rapidly, but his hand remains wrapped around his shaft. His cock twitches in his grasp, begging for stimulation, but he won't allow it. "Hey are you okay-?" You started but you're interrupted by Seonghwa. As if he's forgotten you're there, he starts begging.
"Please Y/n... I'll be a good boy..." He mutters under his breath to himself. The words spill out from his lips like the sweetest wine, intoxicating you. He definitely took you seriously when you asked him to do it like he would if he was alone. "Y/n, please let me come like a good boy for you." He whines and you can't take it anymore. You toss the pillow aside and slide your shorts down to your ankles, slipping your hand into your panties rubbing it just right. "Please, please, do it." You pant as your digits speed up. His ears perk up at the sound of your clothes shuffling and finds the strength to open his eyes and look at you again. When he sees your state- face flushed, hand down your underwear, eyes pleading- he listens to your command. Finally, he allows himself to keep going, choosing a hard and fast pace.
After a few moments he comes, painting his stomach and thighs with white ribbons. It's all too much, and so hot that you quickly finish while your eyes never leave his form. The both of you are left messy and panting.
"Did I do good, hmm? Was I better than those videos you were looking for?" He playfully asks and you groan, feeling embarrassed again.
"Okay, okay you were right. No more videos." You blush.
