———————————————
”Bye, thank you for coming.” Riki says, waving the last person of your friend group goodbye before he shuts the front door.
It’s Riki’s birthday today, so he invited the whole friend group over for a tiny celebration dinner. Currently you’re in the living room taking down some balloons that you’d taped to the ceiling and walls.
He joins you in the living room and removes some serpentines from the coffee table.
”Did you get any good presents?” You ask before popping the balloons with one of your nails.
Riki’s eyes light up as he thinks about the presents he got. ”They’re amazing! I got the Millennium Falcon Lego set from Sunghoon and Jake, and —” he goes on to yap about how cool the Lego set is, you can’t help but chuckle to yourself at his excitement.
About an hour later the two of you are sitting in the kitchen. He has started building the set now, a sea of gray Lego pieces spread out across the table. That’s when you remember your last gift for him.
Earlier you’d given him a chrome hearts hoodie which he was incredibly grateful for. He’s your best friend after all and you want to spend some money on him. You had also gotten him a limited edition anime figure from an anime you can’t remember the name of.
”I’ll be right back, I have another gift for you.”
”Really?” He looks up at you, hands still building absentmindedly. He mumbles something to himself about you being super kind as you walk out of the kitchen.
You come back into the kitchen holding a tiny box, one that you’d usually put jewelry in. Riki takes it and opens it slowly. His entire face becomes red as he sees the inside.
A singular wrapped condom.
”W-what’s this a-about?” He stutters as he avoids your gaze completely.
”Your final present is me.”
”W-what do you— what do you mean?”
”We’ll have sex, unless you really don’t want to…” you respond. But you know he wants to. Sometimes when you wake up late at night you can hear him jerking off in his room, moaning your name. Other times you’ll see him catching glances at your cleavage, which you don’t cover up most of the time anyway.
”I’ve never…”
”I know. I’ll teach you.” You say.
Riki puts the condom in his back pocket before standing up. Arms stuck by his side, looking at you nervously.
”Okay… teach… teach me.” He replies, voice cracking slightly. You reach out and grab his wrist, pulling him with you to your bedroom.
Riki can feel the growing excitement inside of him, it’s visible to you as well. He’s hard. His cock straining against his sweatpants.
You grab his shoulders and guide him to sit down on your bed. He’s unsure where to put his hands, so you have to grab them yourself and place them on your hips as you hover above him.
”Is this okay?” You ask. He nods in response. ”Good.”
You lean down and kiss him, your lips meeting his. Riki isn’t completely sure what to do, trying his best to keep up the pace you’re setting but fails. His chest is heaving and he feels like he’s reached nirvana. Is this really happening? Is he gonna get laid by his best friend? The thought makes him smile sheepishly against your lips. You pull away, a string of saliva connecting the both of you. He whines at the absence of your lips but it’s quickly turned into pleasure as you trail kisses down his neck. A small whimper escapes him as you bite down gently at the nape of his neck. The sound turns you on more than you could imagine. As a reaction you automatically grind your core against his clothed erection.
”Ngh- n-noona…” Riki moans and clutches the fabric of your shirt.
”Are- are you gonna leave marks?” He asks with a shaky voice.
”Do you want me to mark you?” You ask, moving your head up to meet his gaze.
”…mmmh… yes…”
”Hold my hair for me,” you say. Riki immediately gathers your hair with his and at the back of your head like a handheld ponytail. With the hair out of your face you kiss your way down his neck, over his clothes chest and down to his pants where he then looses the grip of your hair. The condom had fallen out of his pocket earlier and is now lying beside his thigh. You pick it up and put it elsewhere while you pull down his pants.
Riki looks at you in awe, there is something so sexy about you wanting to fuck him. It should be obvious, but for Riki it’s not. He lifts his hips to let you pull down his pants and boxers.
His cock stands tall and proudly, the mushroom tip leaking precum like a faucet. He bites his lower lip and his thighs are already trembling.
”So pretty… and it’s all for me tonight…” you say quietly while using your thumb to rub over the slit of his tip. Riki moans loudly, head thrown back against the pillow. A pink blush spreads across his face and down his neck.
”Ahh… ngh-” he moans as you take his cock into your mouth. Your lips soft around his thick shaft. You look up at his face only to see that he’s thrown his arm over his eyes, lower lip trembling under his teeth. Bobbing your head up and down his cock is easy with all the precum he’s leaking. His tip reaches the back of your throat, and you fight against your gag reflex. ”N-noona… I’m gonna… come…”
You pull off of him with a pop sound, gaining yet another whine from him. Slowly he pulls the arm off his face, looking down at you. ”Fuck… you’re so pretty, noona…” he whispers. A satisfied smile spreads across your lips.
”Thank you,”
You stand up on your knees, shimmying down your panties inch by inch. Riki reaches out with his hands to help you pull them down, suddenly feeling very eager to see what’s underneath.
Riki takes in the view of your unclothed pussy, slickness dripping on the inside of your thighs. ”Fuck noona… you’re so wet…” he reaches out and wipes the inside of your thigh with his thumb. Then brings it to his face, licking the slickness off of it. He starts jerking his hips upwards, trying to get some much needed friction. You moan as his tip nudges your folds. Feeling impatient you slowly lower yourself on his dick.
”What about the condom… noona?” He reminds you, looking for it but stop once you respond.
”Save it for another day, we don’t need it…” you say. He accepts it immediately. The slight burning sensation of him stretching you out makes you moan, it feels so good.
”Fuck…. Riki you’re so big…” you moan. Riki responds with a moan of his own as he bottoms out in your pussy. You sit down fully on his dick for a moment, letting yourself adjust to his size. Riki’s knuckles are turning white, grabbing your hips so tight like he’s afraid you’ll disappear. He rolls his head back against the pillows, not daring to look at you because he’s too afraid he’ll come if he does.
”Ah- Ngh…” he moans as you slowly start moving your hips. Not fully lifting yourself off his dick yet. ”N-noona… m’gonna… m’gonna come…” he moans breathlessly.
”Not yet, okay?”
”Ngh- fuck… o-okay…”
Slowly you start lifting yourself off his dick, then lowering yourself again. Bouncing up and down in the most torturous pace just to make him last longer. Losing yourself in the feeling of needing more you start going faster. Riki moans out loud, his cock pulsating inside of you.
You feels his dick shooting ropes of come inside of you. Slowly filling you up with come. A soft moan escapes you.
Riki doesn’t move for a good minute before tilting his head to look at you. ”I-I’m sorry…”
”Don’t be…”
”Noona… I wanna make you come too…” Riki says, you tilt your head in confusion before he turns the both of you around. Pinning you into the mattress and pulling himself out. ”Let me taste you… please noona…” he kisses you down your body to your pussy that is now leaking a mixture of cum and your own juices. His eyes gleam with excitement at the thought of being able to taste you. He reaches your pussy and drags his tongue over your folds.
Your fingers reach down and grab his hair, he moans quietly against your pussy. Looking up at you through his eyelashes to gauge your reaction before he licks faster.
”Ngh- higher up- ah… right- right there” you moan, your thighs tightening around his head. He wraps his lips around your clit and starts sucking. Causing you to arch your back off of the bed and moan his name loudly. The noises coming out of you is music to Riki’s ears. ”R-riki I’m gonna come-” your thighs tighten even more around his head as you come over the edge. He laps up every single drop of your juices, but doesn’t stop. ”R-riki…” you moan.
Trying to pull yourself away but he holds your thighs still with his large hands. When he finally pulls away you see his puffy lips. Your juices coating his lips, nose and chin. He kisses the inside of your thighs and the mound of your pussy for a while, letting you rest before sticking his face back in between your legs.
”Mmh… noona… you taste so good…” he mumbles against your pussy. His tongue darting inside of you. Your grip on his hair tightens as you once again come on his tongue. This time he pulls away, kissing his way back up your face and you taste yourself on his tongue.
”You were so good, Riki…”
”Mmh… thank you, Noona…” he responds, nuzzling into your neck as he holds you close.
Not long after, you both fall asleep.
