summary:Â one of your group mates for research was giving you a hard time just because he was always annoyed by you and the attention the boys are giving you, but you donât know that.
 â
âDing!â a message from Jungkook popped on the top of your screen while searching for the list of equipments you needed for the experiment. Shit, you mentally cursed. You looked up, and everyone in your group was staring at you.
âWhy the hell are you texting when we are still discussing the things we need for this research?â Kim Taehyung snapped. Yes, snapped. This guy was giving you a headache ever since youâve been classmates this school year. He hates you and you donât even know the reason why. Jeongha, one of the girls in your group, smirked.Â
âMaybe one of her boys is texting her for booty calls.â you glared at her.Â
âMaybe you're just jealous that no oneâs texting you.â you said, mimicking her facial expressions.
âShut up, ___. I was asking you why you are texting when weâre discussing our experiment.â Taehyung said out of irritation. This guy. He doesnât even know if I was really texting or not! I need to kick Jeon's ass later for texting me when he knows Iâll be in an important group meeting!
âWell, one of my boys needs me. If youâre done talking, maybe I can leave?â You didnât wait for his response and started to walk away from the group. He is so annoying. Iâll just send my part to Ji-eun later, so I wonât need to interact with Taehyung. Heâs getting on my nerves. You opened Jungkookâs message to check what was so important for him to message you during a group discussion.Â
[1:48 pm] assjeon: â___! I got an invitation to Jiminâs pool party tonight. I know you wonât say no since youâre basically crushing on him since freshman year.â
[1:55 pm] you: âWho said I was crushing on him? Iâm in love!â
[1:56 pm]  assjeon: âYou? In love? Who are you kidding? The party will start at 7 pm, so Iâll pick you up later.âÂ
[1:57 pm] you: âOkay, dad, I got it.â
Good thing his message wasnât that bad and you really needed it. Jungkook was your best friend since high school, so he knows you well enough to judge if youâre in love or not. Of course, I was kidding but damn, who could ever resist THE Park Jimin? Heâs a walking meal for Peteâs sake! His ass looks so good. Any girl would say yes when talking to him. You still had enough time before the pool party so you went to Starbucks to get your favorite drink and went home to take a nap in your flat.Â
â
You closed your laptop after sending Ji-eun the list of equipment you researched earlier before leaving the group meeting. If Taehyung wasnât being an asshole, you wouldâve already finished working on it earlier.Â
It was already 7 pm, and you noticed Jungkook already went inside your flat. He had an extra key in case of an emergency. You got up and picked up the two different bikinis in your bed.
âWhich one should I wear? Black or red?â You tried to put the bikini over your oversized shirt and asked Jungkook to choose your bikini outfit for the party.Â
âIf you wanna seduce Jimin wearing a bikini, I think you should go for the red one. It will suit your curves well.â He said while sipping his iced coffee. He already saw you naked because of one accident wherein your towel accidentally dropped on the floor while the two of you were dancing to the beat of your favorite song. He was flustered, but then he started laughing, so you guessed he didnât care about it. It happened about a year ago, so you donât care about it now.
âOkay. Iâm almost done. Go start the car now or something, Iâll head out after this.â You said while packing some extra clothes in your canvas bag. He nodded and left your flat after leaving his drink on the table. What a jerk, leaving his mess for me to clean up after. Am I his mom or something?Â
 â
 The drive to Jiminâs house went smoothly because Jungkook was a safe driver. There were already many people and some of your mutual friends since you arrived a bit late when you went inside.Â
â___! Here!â Ji-eun called for you. She was seated on a couch with a group of people who youâre not familiar with except one, Taehyung. Heâs with his guy friends, Seokjin and Yoongi. Why was he here though? Oh right, heâs Jiminâs best friend, and he lives here too. How could you forget? Isnât it ironic how you would want Jimin to fuck the shit out of me but hate the nerves of his best friend?
âHey, Ji-eun! Youâre here early. How did the meeting go earlier?â You sat beside her and across Taehyung. He was looking at your figure, and his face screamed in disgust or so you thought. You felt insulted. Most of the guys youâve encountered admire you because they think youâre pretty and hot, but unfortunately, Taehyung isnât one of them. You focused your attention on Ji-eun since she was responding to your question.Â
âOh God, donât even talk about it. Taehyung ended the meeting after you left because he was pissed. Donât worry about it. Letâs go dance!â pissed? Of course, he was pissed. You literally told him that one of your boys needed you while having a meeting. On second thought, he deserved it. He accused you of texting during the discussion where i fact you were focusing on your tasks.
You went to the crowd with Ji-eun to dance. The party was a blast. After a while, you bumped into Jungkook while heâs grinding his hips to the girl heâs dancing with.Â
âThatâs gross, Jeon.â You whispered to his ear before you continued dancing. âYouâre just bitter because Jiminâs talking to a girl, which is not you.â He said and smirked.
 You stopped dancing and scanned your eyes across the room to look for your crush, but instead of him, you locked eyes with Taehyung, who was drinking his liquor on the other side of the room. He was looking at you intensely, and you thought it was hot. Damn, I must be crazy. If he werenât annoying the shit out of you, you would totally have the hots for him. He smirked. You broke the staring contest first and rolled your eyes, continuing the search for your beloved Park Jimin. There he was, talking to the girl who pissed you off earlier, Jeongha.Â
âJi-eun, Iâll get a drink for myself. You can stay here,â you said, and she just nodded as approval.
Jeongha was obviously into him because she kept on touching Jiminâs arms. Disgusting. Siri, please play that should be me by Justin Bieber. You mentally rolled your eyes and walked over to them, bumping into her on purpose.Â
âOh, sorry, I didnât know you were there. By the way, I heard your boyfriend looking all over the place for you.â You said while smiling innocently. You knew this bitch doesnât have a boyfriend but you lied so Jimin would stop talking to her.
âBitch! I have no-â Jimin cut off her sentence.Â
âWaitâyou have a boyfriend, yet you still kept on flirting with me? Get lost, girl.â He said and pushed her away. You smiled secretly like an agent who completed her mission. Jeongha glared at you and walked away.
âSo, ____, do you have a boyfriend?â You slightly jumped because you thought Jiminâs going to walk away too, but he didnât, and he started a conversation between you two! He even knows your name!Â
âIâm not really into relationships.â True enough, you werenât interested in datingâjust plain sex.
âThatâs good to hear, babe. Let me get you a drink. What do you want?â He smirked.Â
âSurprise me.â He winked at you and went to the kitchen to get you a drink. Someone grabbed your arm.Â
âWhat the hell do you think youâre doing?â It was Taehyung. He looked pissed. Why does he look pissed every time heâs talking to me?Â
âWhy do you care?â You asked him back and shot him a glare.Â
âOf course, I care. One second you were grinding your ass with the guy in the dance floor, and now youâre flirting with my best friend!â Taehyungâs mind went ballistic. His mind tells him that heâs just jealous because heâs not the one youâre flirting with, but heâs in denial of his feelings for you.Â
âDamn. Heâs old enough to take care of himself, you moron. And for the record, the guy on the dance floor was my best friend. Stop annoying me and get out of my sight.â you hissed. Did he think I was flirting with Jungkook? I treat Kook like my twin, and now heâs telling me I was grinding my ass on him? Gross.
 âOh, you two know each other?â Jimin handed you a red cup with some sort of alcohol in it.Â
âNo.â both of you answered at the same time. Jimin laughed and just shrugged it off.
âTae, this is ___, and ___, this is Tae, my best friend.â the hell I care, I already know about that. You just smirked and drank every bit of alcohol you had in your cup. You forgot you had a low tolerance with alcohol. âI wanna go for a swim. Do you mind?â you told Jimin.Â
âIâll go with you. Come with us, Tae.â why did he even invite Taehyung to go with you? You wanted to leave because things are starting to get awkward. Didnât he notice the tension?
You started walking towards the outdoor pool and placed your things on the sun lounger. The two guys began to take their shirt off, and you were staring at Taeâs abs. Before he start to notice you, you look away and focused on Jimin instead.
âLike what you see, baby?â he smirked. Damn, heâs hot, and heâs confident about it! Of course he should be. Look at all those girls on the side, drooling over his body. Taehyung dragged him to the side of the pool and pushed him. Both of you were laughing because of Jiminâs reaction.Â
âArenât you going to swim?â Taehyung said and jumped to the pool, not waiting for your response. You forgot what you were supposed to do because you saw Taehyungâs back while he was jumping, and he looked so damn hot.Â
âDamn, I must be drunk,â you whispered to yourself. The water splashing to your legs made you shiver. It was cold.Â
âWhat are you waiting for, kitten?â you didnât hear the last word he said but you saw his lips while saying the word. kitten? What the hell, Taehyung? You slowly take off your oversized tee and shorts, attracting the attention of two men and other people who were near you, revealing your red bikini and your curves. âDamn,â Taehyung thought. Jimin whistled while eyeing you up and down and forced you to jump to his side.Â
 After jumping, you rose and felt someone holding your waist. It was Jimin. He pulled you closer and went for a kiss. âIs this okay?â He asked in between kisses. You responded by placing your arms on his neck and kissing him deeper. Jiminâs fingers slowly traced the inside of your thigh as they slowly traveled up the soft skin. A shiver went down your spine as you realized what was happening.â Jimin,â you said breathily, trying to close your legs.Â
He merely tsked and pried your legs apart with his strong hands. âI know you want it, baby,â he whispered in your ear. Your head was thrown back as he reached his destination, slowly pushing a finger inside you. You look over Jiminâs shoulder and saw Taehyungâs back leaving the pool. Guilt suddenly washed over your face as you realized the both of you were with Taehyung, and you were in public.Â
 âWait, stop,â you said, holding Jiminâs arm while he was starting to thrust his fingers in and out of you. âWhatâs the matter, babe? Donât you like it?â he asked. You liked it, but it felt wrong. âWeâre in public, Chim. Maybe I should go swim for a bit.â he was flustered, but he didnât stop you. He nodded,â Okay then. Iâll just go for a drink.â
You went over to the other side of the pool and observed the people surrounding you. They were busy and having fun enough for them not to notice what you were doing with Jimin. Youâve always wanted Jimin to notice and touch you, but right now, you feel like somethingâs wrong.Â
You got out of the pool and caught some guys looking at your ass. Jungkook was walking towards you and when he got near you, he helped you put on a robe.
âWhatâs up? Jimin told me to give this to you. He didnât look that happy.â he said while drinking from a bottle.
âI donât know, Kook. I just donât feel like fucking right now.â he was surprised but he didnât say anything. Who wouldnât? Even you were surprised. Your main goal when you went to this party was to get laid. What changed your mind? Moreover, who? You didnât care about how Jimin would feel because you knew there were plenty of girls he could screw over. Besides, this is his party.Â
Thatâs when everything got back to you. Kitten. That look in his eyes. Was it Taehyung? He left the pool without a word when he saw his best friend trying to finger-fuck you in the pool. Was he affected? Stupid, of course heâs not. He was just protective of his best friend because he said you were flirting with everyone and he obviously didnât want his friend to get hurt.Â
âDo you want to go home?â Jungkook said while clinging into your arms like a baby. âLet me go otherwise, youâll get wet. And yes, Iâll go home. You can just stay here and look for girls to screw.â you said, grabbing your clothes from the chair beside the pool. âYou sure?â he asked, and you nodded. âAlright, should I inform everyone that the queen is leaving the party?â he laughed out loud, making some heads look over the both of you, while you smacked his head, smiling.
You went to look for the bathroom on the second floor of the house because the first-floor bathroom was taken by some people making out. To your surprise, someone grabbed you and pushed you inside a room.
âWhat the hell?!â to stop you from screaming, he covered your mouth with his lips. His scent was very familiar, but you didnât respond to the kiss. He stopped when he realized you werenât going to react and rested his forehead against your shoulder. The room was dark, and only the moonlight from the window was the light source, so you canât see anything but his silhouette. No way.
âTaehyung?â he didnât respond. You were starting to feel butterflies in your stomach. The only person ever who made you feel like this. Crap. Why is he doing this? Were my thoughts earlier real? Was he really jealous?Â
âStop making me feel like shit, ____,â he said in a husky voice. He smelled and tasted like alcohol, so you figured that he was somewhat drunk. âWhat d-do you mean?â you responded. He moved his face away from you.
âItâs nothing. J-just leave me alone.â did you hear him right? leave him alone? âYou basically dragged me into this room, kissed me, and now youâre asking me to leave? Who do you think you are?â heâs such a jerk! He didnât answer your question but instead, he pulled you closer for a hug. You felt stiff, and you canât even push him away. Heâs making you mad, at the same time, driving you crazy.Â
âI-I,â he sighs knowingly.Â
âYouâre what? Do you think this is some kind of a game?â you slightly pushed him to break the hug. âYou treat me like shit whenever you get the chance, and now you act like a jealous boyfriend? What game are you playiââ Â
âI like you!â He cut you off.
There was a moment of silence.
âYou l-like me?â wow. Iâm lost for words. All he did was get on my nerves, and now heâs confessing his feelings for me? âI liked you ever since. I was jealous because all you do was entertain and date guys that arenât me! What do they have that I donât?â
You honestly donât know what to respond to him. You feel so overwhelmed. You opened your mouth to say something, but nothing went out of it. Taehyung looked rejected and was about to leave when you wrapped your arms around his neck and kissed him passionately. Itâs all or nothing.
âI kind of like you too, Tae.â and with that, he took off your robe and placed his big hands on your ass to carry you without breaking the kiss. He pinned you to the wall and started kissing your jaw down to your neck, leaving soft marks on it. Small whimpers went out of your mouth as your core clenched around nothing when you felt his erection poking your stomach.Â
âTae,â you heavily breathe as he continues to kiss down your collarbone.Â
âTae, please,â
âPlease, what, kitten? What do you want?â he said, slowly dropping you back on your feet. âI need you,â you moaned as he slid his finger down your bikini top and cleavage down to your stomach. You helped him by removing the bikini effortlessly. He sucked your left mound while playing with the other one. An arousal-laced gasp falls from your lips as his hands drop to your inner thighs.Â
 âDo you think you deserve me? After letting my best friend kiss and touch you like that? With me around?â his fingers hook under the fabric of your underwear, and he quickly slides them down your thighs.
âIâm sorry, please, I wonât do it again. I want you now, Tae.âÂ
âWill you be a good girl for me?â you nodded. âI need to hear you say it, kitten.â he looked at you before slowly kneeling so he can be eye to eye level with your pussy.
âYes, daddy. Iâll be a good girl.â
After a swift glance up at your eyes, he leans between your thighs and drags his warm tongue against your clit. The feeling is almost like heaven on earth. His lips are soft, but sinful against your cunt. Itâs not every day you receive oral sex this good, especially not from your oh-so-called-enemy. Taehyungâs right-hand finds comfort gripping your hip while his left-hand cups the flesh of your inner thigh. He lifts your leg to give him a better access for his tongue to enter you.Â
âCan other guys eat you out and pleasure you like this? Hmm?â he said and continued what heâs doing.Â
âNo, baby. No one is as good as you. Fuck, Iâm close.âÂ
You encourage yourself to be vocal to let Taehyung know that heâs making you feel great. When his tongue glides over the perfect area, you tighten your grip on his hair and emit a soft but loud moan. Heâs listening to your vocals and then skillfully dragging his tongue against your most sensitive areas. You looked down at him and saw his erection. It looks painful.
You canât help but wonder how many times heâs done this. Even more intriguing to you, who taught him this. As his palms run along your soft skin, you notice the texture of his hands, slightly calloused and large, too. If he wanted to, he could probably crush you. All this daydreaming has you accelerating closer to your climax, so you quickly tug on his hair and pull away from his mouth. His lips and chin are slick with your arousal.Â
You make it your next move to crawl onto the bed. As you turn to face him, he crashes his lips against yours and guides your almost-bare back to his sheets. The smell of his manly perfume floods your senses. Your tongues greet each other with passion, and the pure intensity of the kiss has you hot and unbothered. He breaks the kiss for a brief moment to tug his shirt over his head and pulls his jeans down along with his boxers. His muscles are well-defined and flex as he leans over to kiss you.
Youâre both aware you need to prepare before taking his cock; otherwise, itâll split you in half. He sank a single finger on your pussy, and you moaned loud enough for him to hear.Â
âI bet Jimin didnât even make you feel like this, huh. Youâre such a slut. This cunt is fucking mine now, you hear me?â
His knuckle stimulates your clit as he gently fucks you with his digit. You wrap your thighs around his torso as he adds another finger. Thereâs a slight warmth from the stretch, but the pleasure almost drowns it out.
âAll yours, Tae. Please, just fuck me already,â you playfully grin.
He got up and went to get something out of his wallet. He rolled the condom over his dick and slowly stroked it up and down. Damn, he looks so fucking hot. âAre you ready for me, baby?â you nodded. Heâs so big. Will that even fit?
He wastes no more time. With a swift adjustment of his body, he positions his cock against your entrance and slowly sinks inch by inch. You dig your nails into the flesh of his back and emit a strangled moan.Â
He sighs at the feeling. âGod, baby, youâre so fucking tight.â
âOh, my fucking..â You gasped. âT-taehyung.â
Just when you thought he couldnât reach any deeper, he pushed back your thigh and sank deeper. You pulled his chest against yours and rolled your hips, signaling him to start his sinful movements. His thrust had your back arching and your thighs shaking like never before.Â
As you go in for another kiss, you take his tongue between your teeth and suck on the muscle, emitting a startled moan from his throat. His hips stutter slightly at the foreign gesture. He grips the headboard as he fucks you with all his might. Heâs been dreaming about this moment since the dawn of time, so heâs going to make the most of it. Your eyes are rolling to the back of your head. Heâs hitting deep and in all the right areas.Â
A deep moan falls from his lips, and then another. He canât seem to contain himself, but youâd be a fool to complain. His shaky breath and pretty moans are drawing you closer to your orgasm.Â
A few more strokes of his hips and youâre moaning loud enough and coming around his cock. He follows closely behind, holding the entirety of his length inside of you and reaching his climax. The pressure is unbearably pleasurable.Â
He lay down beside you as the both of you continued panting. âDid I do great, kitten?â he said as he made you turn to him and pulled you closer, kissing the top of your forehead. âYes, Tae. The best sex Iâve ever had.â you grinned and cuddled him. You canât believe that the guy who you thought hates you made love with you.
 â
 The sunlight woke you up from your deep sleep. You glanced over and realized you were not in your room. Itâs a manly room. You guessed it was Taeâs. Oh, right. Memories from last night clouded your mind, and you blushed. Taehyung was not inside the room, so you figured heâs already downstairs. You checked your phone on the table beside the bed and saw two missed calls and three messages from Jungkook.
 [11:23 pm] assjeon: Hey, where are you? Did you get home safely?Â
[12:02 am] assjeon: Bitch, reply asap. Are you home?Â
[8:09 am] assjeon: Fucking ____. I swear I will kill you if you hurt yourself or whatever you stupid bitch.
His messages made you laugh. Heâs acting like a mad brother. The latest text from him was just twenty minutes ago. You called him, and he answered right after.
 assjeon: where the hell are you, and why didnât you go home last night?!
you: chill, dude. Iâm still here where you left me.
assjeon: by that, do you mean youâre still in Chimâs house?
you: well, obviously.Â
assjeon: thought you wanted to go home because you werenât in the mood for sex last night. What happened?
you: well, itâs a long story. Iâll tell you some other time, kook. Have to go!
assjeon: you better do! Take care of yourself. Love you!
you: love you too.
Call ended.
âWe had sex last night, and the first thing you do in the morning is call another guy?â you stopped scrolling through your phone and looked up. Taehyung was standing there while holding a glass of milk. Cute, you thought.Â
âGood morning to you, too. Are you jealous of Jeon? Heâs basically like a brother to me! Thank you for the milk.â you said, smiling and walking towards him to reach the glass of milk. You noticed you were wearing your undies and an oversized shirt. Taehyung dressed you up while you were sleeping, and you felt those butterflies in your stomach again.Â
He held your waist and pulled you closer so he could leave a kiss on your forehead, and you giggled. âIâm not jealous of him. Just the attention youâre giving him. Good morning, baby girl.âÂ
You gave him a peck on his lips. What a great way to start the morning.Â
End.
a/n: Thank you for reading my first work ever. Do you want a part 2?Â
