[M] Lesson Taught (1/1)

A/N: If you've read my other oneshots, you'll know the dealio by now, I love a bit of teasing ;) So expect slow progression of foreplay~“Thank you so much Sunmi, we’re so thankful” you smiled as you watched Mrs Kim look at you with sheer gratefulness in her eyes.“Don’t worry about it, seriously Mrs Kim, just go out and enjoy yourself with Mr Kim…I’ll take care of Jongin” you got great pleasure from using Kai’s real name which he despised anyone uttering, heck, he barely allowed his own parents to call him that!Tonight, Mr and Mrs Kim had decided to have a double date with their friends who were only in town for the weekend. However, that would mean leaving their bratty son Kai at home alone...It’s not that he was too young to be left at home unattended…but let’s just say, the last time Kai was given the opportunity to have the house to himself, one window had been smashed, two vases had broken and a tonne of ranting from his parents had followed suit.Ever since then, he’d been kept under the watchful eye of his parents, only being allowed out to attend school, or dance classes.You were only a year older, but unlike Kai, you were actually responsible and mature when you needed to be. Of course, Kai absolutely despised you because you seemed to be praised so highly by his parents and that irked him to no ends. Whilst he preferred to party hard and stay out getting drunk with his clique, you preferred to snuggle up in your room enjoying a peaceful night in with your book and a cup of hot chocolate.Total opposites right?Wrong.There was one crucial thing you both shared in common……and that was that you were both total perverts.However, the dissimilarity came about due to the fact that unlike Kai, you weren’t very open about your sexual knowledge. You laughed at the idea of anyone ever finding out just how much you knew…personally, you blamed it on the damn fan-fictions you read. Talk about pent up sexual frustration. (haha)You waved as you watched Mrs Kim join her husband in the car before they zoomed off into the night-time. They didn’t plan to return until around midnight-ish, which meant you had a good couple of hours to kill. Usually when you were asked to keep an eye on Kai, it would just result in you remaining in the living room either watching TV or reading a book, whilst Kai was up in his room watching something on his laptop or playing video games on his playstation.Tonight, it seemed like there would be a change of routine for the both of you…“Where is that moron?” you asked out loud when you noticed that the kitchen and living room showed no signs of Kai’s presence. You didn’t even need to fully scan the rooms; all you needed was a whiff of his strong cologne to know if he was close by or not. Sighing, you settled on the couch in the living room, flicking through the channels on the TV. Somehow you didn’t feel in the mood to watch variety shows or dramas, so resorted to busying yourself on your phone.Yet it seemed that the phone only engaged your interest for about thirty seconds before you found your eyes wandering around the living room again. Your eyes landed on the silver laptop that had been left lying about on the coffee table…With curiosity sparking your actions, you allowed yourself to pick up the laptop and lift the lid to see what contents were on the screen.Eyes widened, you gawped at the porn website that had been left opened on the tab. “Kai, you absolute perv” you muttered as you decided to surf the web and watch something online, something that wasn’t porn. It wasn’t that you were against the idea of watching dirty things; it’s just that you weren’t too keen on ever being caught in the act of reacting to such panty-wetting scenes.You particularly didn't want to be caught by the likes of that idiot boy Kai. “It’s strange how you didn’t freak out at the sight of the porn website” a cool voice filled the room as Kai entered, his mouth taunted into his trademark smirk that made you clench your teeth. It was like that expression never seemed to fade away, and he wore it like a compulsory accessory to his so called ‘badboy’ look. You both went to the same school, and despite the fact he was a year younger, it seemed the girls your age were crazy about Kai. Although you could never pinpoint why when he was such a stuck-up douchebag. “There’s food in the fridge, your mother said to just leave it in the microwave for 2 minutes and it should be ready to eat” you completely skirted around his statement, feeling a little uncomfortable at how he seemed so keen to interrogate you. “Your mother told me to remind you to eat dinner; she said something about how if someone doesn’t remind you then you just forget”You could tell that Kai was clearly annoyed at how you were fussing and acting like such a mother hen…but you couldn’t help it, it was easier to act that way and have him lose interest and ignore you...than have him grill you about why you were comfortable at the sight of a porn website.Yet, Kai didn’t back down. He was one stubborn guy, and what Kai wanted, Kai got.“Not hungry” he stretched his arms, showing no signs of returning to wherever he had been before he’d walked in on you gawping at his laptop. “I didn’t think girls, let alone nerdy girls like you were into porn” he casually stated, watching your thumbs twiddle in a fidgety manner. His words made you pause and look up at him with a smirk.“What on earth made you think I was nerd?”“Am I wrong?”“Absolutely”“Then what are you?”“Never you mind Jongin” you watched as he flinched hearing his name being said. That seemed to shut him up for about 10 seconds as he sighed, running his fingers through his tousled hair. “Come on Sunmi, you can tell me if you watch porn…I won’t judge you.”You snorted with laughter as you fully allowed yourself to focus on Kai as he spoke, putting the laptop to one side. “You won’t judge me because you can’t, since you’re clearly a horny teenaged boy who’s probably watched tonnes of porn” you arched your eyebrows when Kai was about to deny that accusation, but shut his mouth knowing there was no way he could state otherwise, because you spoke the blunt truth.“Okay, well even if that is true, I refuse to believe that you’re the Ms goody-goody two shoes that my parents seem to glorify all the time” Kai leaned in closer tilting his head, there was an undeniable amount of curiosity glimmering in his eyes. Yet, you refused to budge and cave into Kai’s stupid antics of making you crack into admitting something that was rather personal in your opinion.“Okay how about we take this in turns” he began to state, and with a nod of your head you gave him permission to continue his preposition. “I’ll admit something dirty, and then you have to admit something as well…” Kai was grinning lopsidedly, clearly thinking that his plan was fool-proof. Since you were bored out of your mind, you just shrugged in agreement. “Alright fine, you start” you brought your legs up onto the couch and crossed them, making yourself more comfortable as you leaned against a pillow.Kai stroked his chin thoughtfully, thinking carefully about what he wanted to admit. Eventually, his eyes locked with yours before he spoke. “I like when a girl isn’t afraid to top, and takes control when she rides me”His bold words left heat rising to your cheeks as the conversation seemed to take a sudden intimate turn. He chuckled at how your face was turning red. “Aw poor Sunmi, she can’t take my pervertedness…so innocent and pure” outstretching one of his arms, he ruffled the top of your head, making a little growl of irritation slip from your throat.“I’m not innocent”“Oh yeah?” Kai didn’t believe you in the slightest, he decided to humour you by genuinely seeming surprised.“I like guys who make me beg for them to fuck me till I can’t walk”Kai’s jaw hit the ground at the words that he didn’t and couldn’t believe had come from your mouth. You batted your eyelids at Kai, mocking him for thinking that you were innocent, letting a victorious grin fall on your lips. “Your turn”Kai blinked a few times, trying to register that you were actually capable of spewing such dirty lewd ideas. When he got over his shock, he came up with his personal favourite trait in a girl:"I think girls who are a cocktease are the best to be honest. That shit is sexy as hell""Are you sure about that?""Yeah, why wouldn't I be?""Then you've not met a real cocktease, sit down I'll show you what I mean" you sniggered to yourself quietly at the face of Kai who was clearly in disbelief. He scoffed at you, shaking his head profusely. “Sunmi, stop acting like you know how to be a cocktease. Talking big is one thing, but actually proving yourself is another” Kai knew all the right things to say to make irritation build inside you…but somehow you turned that annoyance into determination. You were going to prove to Kai that he wasn’t always right.You shot up from your seat on the couch, before pushing Kai down by the shoulders, so he was now the one sitting down. “You really need to be taught a lesson” you murmured, making Kai raise his eyebrows in amusement.“Go on then, teach me a lesson” his challenging tone spurred you on, giving you the slight bit of confidence you needed to go through with showing Kai that he was going to regret stating that he liked cockteases. Shooting a sultry smirk, you strutted towards him, before landing down on him, straddling his lap. With both your legs on either side of his thighs you purposely let the lower half of your body rub against Kais’ lower half. His hands automatically went to hold you steady by your sides, but you smacked his hands away. “No, you don’t get to touch” you purred seductively, before unbuckling the belt from your jean shorts. Kai’s eyes widened slightly feeling you place his hands behind his back before you tied a knot with your belt, leaving him incapable to grab you even if he wanted to.“Sunmi I—”You silenced him quickly by putting a finger to his lips, before bringing your mouth close to his ear. “Cockteases would probably begin by making you want you them bad” you whispered, your lips gently planting little pecks against his oh so chiselled jawline. You smirked against his skin when you felt Kai’s jaw ever so slightly tighten, he was clearly enjoying the kisses but he was way too stubborn to ever admit that. Moving your hands to explore underneath his t-shirt, you secretly loved how firm and toned his bare torso was. Your cool fingertips against his hard abs made a tingle shoot through Kai’s body as he closed his eyes tightly letting his sensations overpower him. You lowered yourself so you could let your lips plant itself just above his navel, sucking passionately and leaving a very big red notable hickey. Kai bit his lip, feeling a sudden rush down south to his member, his jeans tightening a little.“I want you to take me from behind, pull my hair and make me scream your name” you purred as you brought yourself back up to allow your hands to grip Kai’s tousled locks. Pulling his hair gently, yet firmly to the side, you sucked harshly on his neck. When you began to leave a love bite in a sensitive spot, Kai involuntarily let a moan of appreciation escape his throat. “Sunmi stop” Kai’s dangerously low tone and lust-filled eyes made you felt triumphant, but no, you weren’t done yet. Not even close.“Why?” you blinked innocently, stifling a giggle at how Kai was drilling his eyes into you, thinking about only God knows what. “Untie me” he commanded, although his voice didn’t seem harsh, it was more so a pleading tone that you didn’t fail to pick up on. Ignoring his plea, you arched your eyebrows at the noticeable bulge in his trousers. “Did I do this?” you grinned, as you leaned into Kai’s chest, your breasts against him made him whimper slightly….Although he was never expecting you to begin to palm his member through his jeans.“Fuck!” his hiss was in pleasure as he felt your hand make contact against his now fully erect member. Your lips found their way to his earlobe, which you eagerly nibbled and sucked, the sensations of your breasts, your licks, and your contact with his member was driving Kai utterly insane.“Alright, fine!” he growled. “I admit cockteases aren’t good” his defeat didn’t seem that genuine to you, it was almost like he was just admitting defeat to get you to stop torturing him in such a unbearable manner.Within a second, all action stopped as you pulled yourself away from his ear and moved your hands from his body. Instead Kai gawped at how you tore yourself away from his lap, but remained in his view. His vision drank in your tantalising figure, how had he never realised before how delectable your ass was?“You know what the worse part about a cocktease is?” you asked, as you began to shimmy out of your jean shorts, allowing Kai
