Screams bellow out from the television as it flashes bright lights of whites and reds into the darkness of the room. I lean in closer to Taehyung, his arm wrapped tightly around me as we watch the low budget horror movie intently; it’s the kind of movie that’s so bad it’s entertaining. His thumb rubs my shoulder soothingly as he periodically pulls me closer- never able to bring me close enough to his liking. Jimin comes in, sitting down on the other side of me, placing a hand on my thigh confidently as he stares at the screen with us.
“What is this that you’re watching?” He asks, his voice low and questioning. “It looks kind of stupid.”
“If you don’t like it then leave,” Taehyung says in a kind voice, almost cheery and playful despite the words and the small hint of irritation from the intimate touching towards me. His eyes move to the hand on my thigh, watching it with an oddly cool, collected emotion.
Jimin chuckles a little under his breath, nudging me playfully. “You like these kinds of movies? Or did he drag you into watching it?”
I smile at him politely, “I chose this one actually. We take turns trying to find the worst possible movie.”
“Ah, I see. Well, even with this choice he still chooses worse ones. You definitely have better taste-”
“I’m going to the bathroom. I’ll be back.” Taehyung says, moving away from me and getting up abruptly, his form quickly disappearing into the other room.
“What was that about?” Jimin asks, looking at me surprised before leaning in. “Did you see his phone lighting up?”
“What are you talking about?” I ask, looking at him with the same look of surprise. “That’s really random.”
“He’s been talking to another girl recently.”
I can feel a weight drop in my stomach as I frown a little, confusion filling my head. “What do you mean he’s been talking to a girl?”
“He’s been messaging some girl a lot. And it isn’t you.”
“How do you know it isn’t me?” My tone is slightly accusatory as I ask this, my emotions rising in my body. I can feel my cheeks burning from confusion and embarrassment. This is a joke, that’s not like Tae.
“I saw the messages, it’s an old fling of his from last year.”
“Well… there’s nothing wrong with him talking to female friends. I doubt the messages were anything out of line.” I bite my lip, trying to hold in my doubts. There’s just no way…
“She was the girl before you, she dumped him so he didn’t take it too well. It looks like they’ve made up recently, they seemed awfully close for just friends. Talking about going to get coffee or see a movie soon.” He leans in closer to me, his head hovering over my shoulder and I suddenly feel claustrophobic- moving away from him quickly.
“Maybe they have already met up. His phone is right there. Why don’t you check it? It’s been lighting up every other minute since I came in here.”
I look over at Taehyung’s phone on the arm of the couch. Jimin isn’t lying, I’ve seen the phone light up many times since the movie started. I lean over, not grabbing the phone but instead hitting the home button- seeing a girl’s name pop up over and over again. I feel sick as I struggle to read some of the messages from a distance.
“Taehyunggie, why won’t you answer me?”
“When do you want to see each other again?”
“Next time we see each other you should wear that scarf again~ you looked so handsome.”
“Taehyunggie~ stop being so stubborn and answer me. Are you with your girlfriend?”
My heart races as I read message after message, finally letting the screen go black as I sit back normally, staring at the paused tv in silence.
“See, I wouldn’t lie to you,” his voice is smooth and calm- so much so that it makes me even more uncomfortable. “I felt bad seeing him message her so much, I felt like I needed to tell you to protect you.”
“I’m leaving,” I say suddenly, starting to get up when Jimin pulls me back down.
“No, what. Why? So soon? Stay here with me.”
“Yeah, not happening.” Shoving him away I stand up, pulling on my cardigan from the nearby chair when Taehyung walks back in with Jin in tow.
“Jimin... Why don’t you leave them alone and come to my room- oh? Are you leaving, Y/N?” Jin’s voice is surprised and gentle as he watches me along with Tae.
“Babe, what are you doing?”
“I don’t want to talk to you right now, Tae. I’m leaving, I’ll call you later.” I brush past him quickly, my blood boiling as I go to the door to slip on my shoes.
“Woah, woah. Wait up, what’s wrong? You’re just leaving like that? Why?” His voice is confused as he stands in front of the door, keeping me from leaving as I slip on my second shoe.
“Move.” My voice is stern and serious as I try to push past him again. “Let me leave.”
“Not until you tell me what’s wrong. Did Jimin say something to you? Everything was fine until I left…” He looks down at me, his dark eyes staring at me worriedly. It makes me feel nauseous thinking that he could pretend like he cares so easily when he’s been talking to another girl. If he’s been talking to another girl like that? Had he? Maybe it was just innocent... My head starts to hurt from the back and forth thoughts and I feel trapped.
“MOVE!” I scream, causing him to jump a little in surprise. I can feel my face reddening from embarrassment and anger as more of the members come into the room, watching our fight.
“Hyung, let her leave.” I can hear Jungkook say softy from behind me, his presence appearing close to me as he leans over to pull Tae away, Taehyung complies and gives me room to leave.
I nearly run out the door, clinging to my purse as I run down the stairs from their dorm. I can feel tears pricking at my eyes as I run outside, the early stages of rain starting to fall around me.
“Oh, this is just fucking fantastic.” I say, looking up at the sky. What a time for this weather. The tears start to fall, being masked by the droplets that are soaking my body, and I walk toward the subway station. I just need to get home and relax. I just need to get away from here to have some time to think.
~•~•~•~•~•~•~•~•~•~•~•~•~•~
Taehyung: “Hey, Y/N. It’s been a week since I’ve seen you. Can I come over? Or will you come over here? We need to talk.”
I stare at my phone as I lay on my bed. I’ve been avoiding him this entire time and I know it’s not making anything better. What if none of it is even true? I did see the messages, but…
I click respond and my fingers hesitate over the keyboard. It’d be better to go to his place since the other members will be there. If something happens and we get into a fight again then they can back me up.
Me: “I’ll come over tonight for a little while.”
Taehyung: “Jimin told me why you’re upset.”
Me: “We’ll talk when I get there.”
Taehyung: “Do you really believe that I’d do that to you? You’re the only girl I love and I’ll prove it to you.”
I stare at the message, my heart squeezing tightly in my chest. What should I believe? He’s never been the kind of guy to cheat and he’s never given any indication of being like that at all- even secretly.
I take a shower, going through all my beauty routines as usual. Looking into the mirror I bite my lip a little. I don’t want to come off as trying too hard, maybe I should tone it down and do only a little makeup. After applying mascara I settle for only that, throwing on a simple skirt and blouse that I know are his favorites. If he really did cheat on me then I want him to see what he’s losing.
~•~•~•~•~•~•~•~•~•~•~•~•~•~
I hesitate as I stand outside the dorm, not wanting to go in, yet. What kind of excuses will he have? Are they excuses or the truth? What should I believe?
“Y/N.” I turn abruptly, my heart almost stopping until I see who it is- Jungkook.
“Kookie, don’t scare me like that.” I say, holding my heart as he walks over to me.
“Sorry, you’ve been standing there for a while. You ok?” His voice is soft and concerned, causing me to relax a little as I look up at him.
“Honestly, no. I’m nervous to see Taehyung.”
“Why is that?”
“Do you really not know?”
“I mean… I heard him arguing with Jimin hyung the other day.” He looks up as he thinks, “he was mad that Jimin lied about something.”
“Is that so?” I look down. “But why would Jimin lie? That’s not like him, is it?”
“No. But everyone thinks Jimin likes you. They fight a lot because of it.”
That would explain him always being so touchy with me. But who is the girl? The messages weren’t fake… He didn’t make her up, so there must be some truth to his words.
“I’m going to go now, Jungkook. Thank you for checking on me.”
“Yeah, no problem. Here, I’m going up, too. I’ll let you in.” I follow him up the stairs and he opens the door for me, letting me enter first. No one is in the living room so I assume they’re in their rooms. “Just go to his room, he should be in there.”
I nod and thank Jungkook before walking to Taehyung’s room, pressing my ear against it curiously before knocking, hearing soft piano music playing inside.
“Come in.”
I open the door timidly, peeking inside to see Taehyung on his bed, reading a book. He looks up and sees me, his eyes widening as he jumps up to great me. “Y/N!”
I refuse to look at him, looking down at the floor instead. Don’t get distracted by his good looks. Stay strong and focused. Something is going on and I need to figure it out first.
“You’re acting that way… Do you really think I’d cheat on you?” He asks softly, his voice a deep rumble.
“I don’t know what to think, Tae. I saw the messages on your phone and Jimin was so adamant…”
“Jimin is just causing trouble because he’s liked you for so long and wants to take you from me.” He moves closer to me, causing me to back up against the wall.
“Who is she?” I ask boldly, still refusing to look at him.
“She is an old girlfriend and close friend. We broke up over a year ago. Before I even met you.” He moves closer to me again.
“Then why were you talking to her?” My voice breaks a little as I bite my lip, holding back tears as the topic pricks at my emotions. “Did you meet up with her?”
He stays quiet for a moment before saying in a low voice, “yes, I did.”
A deep cry escapes from my throat as I turn to leave, not wanting to hear anymore. His arms are suddenly on both sides of me as I’m cornered, not able to leave.
“Y/N, listen it’s not what you think, nothing happened. She knew from the beginning that I had a girlfriend, I would never do anything to hurt you or lose you.” His voice is genuine and panicked as I still struggle to hide my face and escape. He moves a hand to my chin, making me look at him. “Nothing happened between us. We got coffee and that’s it.”
“I’m confused, Tae. Why would you see her in the first place? Why didn’t you tell me beforehand? Why did I have to learn about it from your stupid group member and why was she talking to you in such a flirty way? All these things, did you not care enough about me to tell me any of it?”
His lips meet mine quickly, silencing me as he pulls me to him. “I do care about you,” he whispers softly as he pulls away, “and I love you more than anything. And if I have to prove that to you then I will.”
“How could you-” suddenly I’m lifted up into his arms as he carries me over to his bed, laying me down onto it gently. “Tae, what are you doing?”
“Let me show you,” his body hovers over mine as he kisses softly down from my lips to my neck, each kiss delicate against my skin. His hands caress my body and all the frustration that I had starts to melt away as I find myself missing his touch.
He starts to kiss slowly down my body, lifting my shirt up to show my chest. He kisses the top of each one before lifting my shirt over my head. Part of me wants to object, to yell at him and tell him not to touch me because I’m still upset over the situation. But I’ve missed his hands on me, missed him this close to me, and all of his actions are following what he’s saying. His slow movements are full of so much care, like I’m something precious and breakable to him. He’s always been this way with me, despite me constantly telling him that I want to try other things.
My bra is pushed down as he takes one of my nipples in his mouth, his tongue rolling over it slowly in little circles, his hand massaging the other tenderly. I sigh out a little at the contact, the heat from his mouth sending a shiver down my body.
I move a hand to his hair, running my fingers through it as I admire how thick and soft it is. It’s a nice chocolate brown right now instead of any of the crazy colors he’s had recently with the new comebacks. He moans softly at my touch, his large beautiful eyes looking up at my face causing me to blush and look away.
He smiles against my skin, moving up to me to kiss my cheeks then my lips when I face him. “Can I?” He asks, his hand traveling down to my skirt. I blush more, nodding my head timidly.
He curls his fingers around the fabric, pulling it down off of me, leaving me in only my bra and underwear. He gets on his knees on the floor, pulling my legs until his face is even with my crotch. Slowly he runs his fingers over the fabric, pressing against my slit then my clit. I move my hips a little in response, causing a grin to cross his lips.
He slides my panties out of the way and moves closer, his hot breath tickling the now cold skin. I squirm as his tongue enters me, poking curiously inside and at my folds.
“Oh, fuck…” I say softly, the words leaving my lips easily as he continues to look up at me, watching my eyes close and head roll back from his tongue. He slides his fingers into me, moving his mouth to my clit as he smothers it with his lips, the warm feeling consuming me as he starts to hum, the vibrations tickling me, sending shivers through my body.
My hands grasp his bed sheets as he curls his finger inside me, massaging and tickling my insides aggressively, yet gently. I can’t stop my body from squirming as a feeling starts building up inside of me as he fingers my sensitive nerves. Taehyung retreats his fingers long enough to wrap his arms around my thighs, holding me in place as he penetrates me again, his tongue moving faster now, flicking my clit strongly.
“Tae, I can’t…” I mutter, struggling to find words as my body moves closer and closer to climax, shaking against his lips and arms as it’s racked with pleasure and warmth.
Moving positions he starts to rub my clit, shoving his tongue back into me as the new pressure and speed to my sensitive spot sends me over the edge. I arch my back as I try to hold in my moan, quickly being silenced by one of his hands while the other continues to force on the orgasm, still rubbing and teasing as I try to move my body away from the intensity.
My eyes roll back as I shake against him, his warm weight on top of me as my high calms, soaking into me. He removes his hands, kissing me softly of the neck as I moan softly. I look at him, his face soft as he moves his kisses to between my breasts. His long eyelashes kiss his cheeks as he focuses on each kiss, each caress on my skin done by his lips.
My heart aches and I put my hand on his cheek, “I believe you, I believe nothing happened with her. But… I don’t like that she was being flirty, especially since you hadn’t told me about her.”
“I honestly didn’t even know she was flirty. I don’t feel anything for her anymore and I truly thought it was innocent, I felt nothing on my end. Now I know, I’ll let you know immediately next time. I won’t talk to her anymore.” His voice is low but genuine, his warm eyes looking deeply into mine as he talks.
“You don’t have to stop talking to her… I just don’t like her flirting with you.” I say softly, not wanting to be the kind of dictating girlfriend.
“Still, this has caused more trouble than it’s worth. And we’re not really friends, no harm in ending it. I don’t want anything to make me lose you, you’re mine.” He smiles softly, his eyes showing deep emotions and care.
I smile back at him before becoming more aware of his body pressed against mine, grinning as I feel something that makes my stomach reheat and burn like lava.
“Taehyung, I want you to show me just how much of yours I am.” My hand travels down his body, cupping his hardness. He must have gotten excited while pleasuring me, holding back this whole time.
“Oh really now?” He chuckles, biting his lip as my hand massages him. “Well, you know I’ll do anything you ask of me…”
With these words he sits up, pulling his shirt over his head before flinging it across the room. I bite my lip as I stare at his body, lean and tan. He doesn’t have a 6 pack, but I’ve never thought he needed one. His body is perfect enough as is. Standing up on the bed, wobbling a little as he tries to gain balance, he strips from his pants until he’s fully bare like me, pulling my legs apart as he falls between them, causing me to laugh as we both bounce on the mattress.
“You’re such a dork, why do I date you again?” I laugh as he leans over to kiss me, our lips meeting continuously in small peppered kisses.
“Because you love me and I love you,” he says sweetly before leaning close to my ear, his arms pulling me closer to line himself up with me, his tip brushing against my entrance. “And I fuck you better than anyone else.”
“Oh, yeah? Remind me how you fuck me.” I tease, moving my hand down and wrapping it around his dick, leading him into me slowly, both of us sucking in a breath as he pushes in fully, taking control. He leans over me, rocking his hips back and forth as he starts to thrust into me, each one going deeper as he pulls my legs to go up over his shoulders.
I moan loudly as he dives in deeper, filling me up fully as I start to move my hips against his, using his shoulders as leverage. Grunts escape his throat as he speeds up, skin slapping loudly as I move my hand up to his chest, running it down his soft, smooth skin. Eyeing him all over I take in the beauty of his body, the way his chest gleams as small drops of sweat start to bead on it, his face focused into a pleasured frown as he leans further down onto me.
“Fuck, you feel so good,” he moans into my ear as I wrap my legs now around his waist, my body feeling hotter and hotter with each thrust.
“You’re mine,” I whisper back to him, pushing him a little until he moves away, confused. I flip him onto his back, straddling him quickly before repositioning his cock back to my pussy, sliding down on top of him as I ride him. My hips move in circles, my body deeply penetrated in a way that makes it hard for me to think. He groans loudly, his hands traveling up to my breasts, squeezing them tightly before moving to my neck, tracing my skin with his fingers before adding small pressure. I roll my head back, enjoying the small kink that he does to me sometimes. He grins at my reaction, biting his lip as he squeezes a little more.
He sits up, his hand still around my throat as the other holds me to him. He kisses he roughly as he thumbs my throat hardly. His arm tightens around me, helping me move faster as our bodies cling together and his thumb travels to under my chin as he bites and tugs at my lip. “Tae, I can’t hold it much longer,” I say as the familiar knot from earlier reappears inside of me, building and building, growing closer to falling off the edge.
“Cum for me, fuck, I want to hear you moan out my name as you twitch around me,” his voice is a deep grumble, his hands tightening around me as he moves me faster, each thrust making my core feel hotter and hotter as he whispers more lewd words into my ears and his hand makes it harder for me to breathe. “Come on, baby, show me who I belong to, show me what I do to you.”
“Fuck, Tae…” I groan as an explosion erupts inside of me. My body tries to lunge away from his quickly, but he holds me down, continuing to fuck me as my orgasm explodes all over him. Twitching and squeezing his swollen cock as I squirm, trying to get away from the increasing pressure.
He flips me back over onto my back, thrusting hard and fast as I whimper, my most sensitive area continuing to be rammed and pleasured. Suddenly, he cries out as his movements falter, becoming jagged and slower as he releases himself into my pussy, his warmth invading even more of me.
He stays above me for a moment, both of us breathing heavy as we try to recover from our highs, looking at each other deeply before he leans down to kiss me passionately. He pulls out and falls beside me, immediately cuddling me to his chest. “Don’t doubt me again. And I promise I won’t give you a reason to ever doubt me again.”
“Deal,” I say softly, resting my head on his chest as my eyes start to become heavy as my entire body throbs. “And tell Jimin that I’m not interested in his advances or “help” next time.”
“I don’t think we’ll have a problem, the walls are thin,” he says with a wide grin.
I bury my face against him and sigh, “ugh… well at least they know we’re back together now.”
“And they know how vocal you are for me,” he kisses my cheek playfully and I frown.
“Oh shut up, Tae.”
