You find Seungkwan where you knew he would be. In his office at home, surrounded by colorful paper.
Hanging along the walls were certificates for his degree in education, mixed in with his students' chaotic drawings, littered with sparkly glitter and glue, and photos of you two in different stages in your relationship.
Seungkwan has been an elementary school teacher for seven years now. After making it so far in his favorite sport, volleyball, his injuries forced him to retire, to slow down, and it resulted in him doing his second favorite thing other than volleyball - teaching kids.
There was a different kind of sparkle that came to Seungkwan’s eyes when he was in a classroom full of students. It brought the softest parts of him out, quick to kneel to the little one’s heights when talking with them, a soft voice and softer eyes. A fierce and passionate rally of encouragement would overtake him when classrooms were racing against one another during “spirit week,” and Seungkwan would rather die than have his class lose to Mr.Soonyoung’s class!
He even volunteered to be an assistant coach alongside the P.E. teacher, Mingyu, to help his kids have fun during a game of dodgeball or kickball. And it’s why you find him now, hunched over his desk, organizing colored paper into stacks for the next activity he planned to do in his classroom tomorrow. The holidays are around the corner, and he wanted his kids to make paper chains they could decorate in their own homes for the winter holidays.
You smile fondly, your hip leaning against the door frame as you watch him work. His eyebrows knitted together in concentration, his fingers moving quickly. When he turns in his rolling chair, he winces, and you’re brought back to why he retired from his favorite sport. His injury to his hip and pelvis tended to get more tender when the colder weather was back in season.
“Okay,” your voice rings out and gains all of his attention at once. “I think that’s enough for one night, come relax.” You nod your head back to where the living room is, and Seungkwan pouts.
“Wait, I’m almost done, I swear!” He’s already shuffling more papers; giving you big eyes like that would somehow make you fold. It would. “You can sit on my lap while I finish up, and then we can go to bed, I swear.”
You snort, rolling your eyes playfully, your usual teasing joke already slipping past your lips. “I don’t think you can handle me sitting in your lap, Old Man.” You had started saying that nickname to him because of his old injury. Seungkwan, yes, was older in age, but it was the injury that made him act like it. You had caught him many times, slightly leaning forward and shuffling to wherever he was going, and it would always bring a laugh out of you. Your coos are only making Seungkwan blush and roll his eyes.
“Old Man,” he huffs, fully knowing you’re teasing him, but rage baiter meets rager, and he falls for it every time. “You weren’t thinking I was an old man when I made you cum on my tongue three times last night.”
The memory flashes through your head, you're sprawled out on the bed with his head between your thighs. Your giggles stop, your thighs pressing together for relief as you take your turn to blush. “Don’t even start, I bet that’s why you're wincing more than usual after trying to fuck me into the mattress.”
Seungkwan fully drops his papers to the side, turning his chair to fully face you, his legs spread wide as he leans back smugly. “What can I say? I aim to please, and I’m pretty sure I left you more than satisfied.” He tracks your tongue wetting your lips, his smirk growing as the air shifted in the small home office. “Tell me I’m wrong. Tell me you’re not wet just thinking about it.” You hate how right he is. How your body responds so easily to his, your arousal flooding between your legs. “Mm, that’s what I thought.” He flashes you a cocky grin you want to wipe off his face. “Say thank you.”
And that’s when you have an idea.
“I’m waiting,” Seungkwan is raising a brow, a teasing grin dancing on his face, when you take a step closer. Then another, and another until you’re standing between his spread legs.
“You want me to say thank you?” You ask, your voice coming off in a whisper - you can see his lips part, his eyes dilating as he nods his head. “Can I just show you?”
…..
Vulgar, sloppy, and lewdly slick noises echo in the small home office. They mix with a gag here and there that has Seungkwan seeing stars burst behind his eyelids.
You’re a sight to see, kneeling between his thighs, your watery eyes staring up at him as you sink your mouth onto his cock for the nth time.
It’s been hours. Or what feels like hours to Seungkwan, of you teasing him, edging him to the brink of insanity as you bob your head up n’ down. Your warm, wet mouth is slurping his cock all the way to the base and triggering your own gag reflex. Your knees dug into the wool rug in his office as you swirled your tongue around his fat tip, earning another broken gasp from him.
“O-oh my god,” and his eyes roll to the back of his cranium, tongue lolling out. He’s so thick, the veins running down his shaft throb in need under your tongue, and his lungs shake to breathe properly. “More, more, please, please.” He’s babbling, drool forming at his mouth as you let him reach the back of your throat with a low hum. “Fuh-fuck tha’s it, jus’ like that - relax that throat f’me, yes, yes, keep me nice n’ warm.”
You can feel your own drool slobber on his cock and seep down to his cum-filled balls. And it’s got another wave of your arousal seeping onto your ruined panties. Each time you bob your head farther down his cock, his length stretches your mouth and brings a delicious ache to your jaw. Your fingers dig into his thighs, your airway choked, and nasty slurps resonate in the room.
Seungkwan’s entire body feels hot, like he’s a live wire, his abs flexing each time you swallow him more. “Oh fuck, oh, oh, m’gonna cum! M’gonna cum,” he’s whining, tears springing to his eyes as you pick up the pace and attempt to suck his soul outta him. Your hand moves to milk the rest of him as your mouth overstimulates his bulbous tip like it's a popsicle.
You get his legs shaking, his fingers gripping the armrests of his chair as he thrashes in pleasure. And right when he’s about to fill your mouth with his seed? You stop, pulling your mouth off his crown as your hand squeezes his base, preventing his release.
He whines, high-pitched and broken.
When Seungkwan looks down at you, his eyes are glassy, his lips spit-slicked and puffy from him biting them. He’s panting, ears ringing, and the tears spill down his cheeks. “W-why’d you stop?” He hiccups and you coo, pumping his cock in your fist and watching his body twitch in response. This was the fourth time you’d done this tonight, and he really didn’t know how much more he could take.
“You look so pretty, jus’ wanna keep you like this.” You hum, and Seungkwan’s heart flutters; his face is flushed all the way down to his neck. He sniffles, blinking heavily, trying to speak, but his tongue just feels too heavy. “I could suck your cock for hours, love how it feels in my mouth - warm, big, and heavy on my tongue. I get so wet when you reach the back of my throat-” your words pull a needy whine from his mouth, and he’s bucking his hips up into your fist like it’s your pussy.
“Wanna- oh fuck,” his throat bobs, his mouth dries, and he’s struggling to find the words. Your pretty mouth rendering him speechless. “Please,” he begs, and you coo again.
“What do you want? Want to keep fucking my hand all desperate? Or do you wanna cum down my throat until I’ve milked you dry?” Your tongue laps his tip, and he shudders, jaw slacking open as his eyes roll back. “Or are you thinking about my pretty pussy?”
Seungkwan breaks, he’s reached his limit, and he grabs the back of your head, shoving your head down on his heavy cock again. He shuts you up, stuffing your mouth and throat with his length until the only sounds your mouth can make are muffled moans. He holds you in place and bucks his hips, using your mouth like he would use your pussy. Fucking your throat raw and getting you to slobber more down his shaft. It’s sloppy, messy, and dirty. His groans are loud and unabashed as he fucks your throat, his cock twitching against your wet mouth. “Jus’ like that, take it all, so good f'me.”
It only takes a few more rough thrusts from him before he’s flooding your mouth with his edged orgasm. His tip spills rope after rope of his white, hot sticky cum, and his hand cups your cheek as you do your best to take it all. “There we go, swallow it all, that’s it.”
When he’s able to finally slip from your mouth, his cock is sensitive and throbbing still, and you catch his eyes with a grin. You stick your tongue out, showing you’ve swallowed every last drop from him.
“Thank you,” you finally say and give his softening cock a sweet kiss, and it’s got him groaning all over again.
“C’mere,” he huffs, pulling you up onto his lap so he can kiss you. When his hand slips under your shorts, you swat his chest lightly, reminding him of his sore pelvis. But it doesn’t deter him, he’s swiftly sitting you onto his desk and laying you back. “I don’t need to use my pelvis to get you screaming on my mouth, spread your legs, Pretty.”
He's going to have to reorganize his papers in the morning.
