Back theory | KNJ
Inspired by insanely buff Joon pictures that dropped today. Also I needed to make sure my friend can imagine what is like to feel a heavy, buff Joon on her 🤭 Love you Sam!
!Warnings: +18
Your phone buzzed in your pocket. You took it out and saw a text message from the man you have been missing so much lately.
KNJ 8:45pm I can’t wait to get out of here. Another day where I felt useless as fuck. Honestly get me out of here already.
You chuckled reading the message. You received a message like that twice a week at least. He would moan about feeling useless and wanting to get out of his military service often. There were days when he felt proud to serve and when he achieved something, you would know about it the same evening. His free time was limited and so was his time off. Because of that last time you have seen him was few months ago and when you did it was only for a short amount of time. You had a coffee and a short walk around the park and then a meal together. There wasn’t enough of alone time. One on one time. Any sexy time. You have seen he has changed. Physically and mentally. Mentally he has been softer, there has been much more yearning going on, he was needy and he would occasionally send you a text or a picture with him admitting how much he misses you. Physically he has gotten bigger, bigger in general. At first you thought it was because he wasn’t dealing well with the fact that he was locked up there for a year and a half. He would just eat more than usual and skipped workouts. But you couldn’t have been more wrong, because he spent so much time exercising that all the weight he gained was already turned into muscle. At least that’s what you saw on the very last picture you found of him online. You weren’t doing it often but you knew you could find some of the more recent pictures of him floating around the web, because the fans just like you were yearning to Kim Namjoon. They were curious how was he doing and if he has changed at all.
KNJ 8:55pm I swear the day that I am out of here will be happiest day of my life. Second happiest. The first one was when you agreed to date me.
Another messaged popped on your phone. You smiled again. You were still thinking how to comfort him through the screen of a phone. What could you possibly say to him to make him feel better, less lonely, less like he should escape that place.
‘I miss you so much, when can I see you next?’ you responded to his text and locked your phone. You were in the middle of cooking yourself very late dinner. You were so busy all day and stayed at work longer than usually and completely forgot to eat. Your phone chimed again.
KNJ 9:01pm Soon angel, soon.
You didn’t know what kind of soon he had in mind. You didn’t want to know either. The days would only go by longer and as much as you would love to count them down, it was just easier not to. You have pulled the pasta out of the pot and strained it in the sink. The sauce was also ready and you poured it all over the pasta, grabbed glass of wine that has been your cooking companion since you got home. Tomorrow was Saturday and you were really looking forward to your weekly cleaning schedule. Religiously, every Saturday you would go around your entire flat and clean every nook and cranny. It was part of your routine that helped you feel grounded and in control. Because if you didn’t manage to ground yourself this way, you would be upset, ugly crying in your pillow all day missing Joon. It was difficult. It was worse than you thought it would be. When he announced that he will have to enlist, your heart broke into millions of pieces. You were unsure whether he would even continue your relationship in this scenario. Being away from him wasn’t unusual, but it felt more restraining. You knew you wouldn’t be able to be surprised by him coming from tour one day early, or fly you over to a random concert so you could watch from backstage and spend few hours together. But this felt different. It felt like he was further away than when he was on the other side of the world. You felt empty without him, because he was your home. You didn’t live together and there weren’t any recent mentions of this to change, yet still he was your comfort. Your home. And you were his. He very rarely would open up in front of you, but when he did, he made you realised how much he appreciated you, how much he loved you and how much of a safe zone you were for him.
You finished your pasta and your wine and were considering having another glass. But you decided against it, got up from your table and cleaned up after your dinner. Your phone buzzed again and you were hoping it was Joon but it was just a junk mail, about free vouchers you can claim. Since you already had your phone out you decided to snoop about the internet again and see if there was any newer pictures of your own boyfriend. How low have you stooped and how much have you been missing him to resort to looking him up. But you couldn’t find anything new. It was getting even later in the night and after a really long and tiring weekend you decided to get in bed and unplug. You have gotten ready for bed, brushed your teeth and completed your extended skin care routine, which you have always done on the weekends. You looked at the time and it was past 10 in the evening already. You turned all the lights in the apartment and got into your really cosy bed. You thought you might have trouble sleeping, but the second your head hit the pillow you felt like you’re floating and sailing away. Before you did actually fall asleep you sent a text to Namjoon: ‘Goodnight my love’. But you didn’t wait for an answer. You knew the answer might never come, at least not this evening. You put your phone away and closed your eyes. It was time for a sweet rest you felt like you deserved after the entire week of hustling.
The door lock clicked and a pair of heavy boots walked into the flat. The thumbing didn’t last very long and it got changed for a very quiet sliding noise. Quiet steps making their way to your bedroom. And you had no idea, sound asleep. Occasionally snoring and turning around. He walked into your bedroom and stood by the door. The moonlight poking through your unevenly closed curtains, straight at the bed, lighting your sleepy face. He would of sworn he could have looked at you like that for hours. But there was no time to waste. He slowly made his way around the bed towards the somewhat empty side of the bed. He slowly put his legs on top of the duvet and slowly put all of his weight on that side of the bed. You felt it but you only moved a little and turned around to face away. You were a heavy sleeper and at this very moment Joon wished you weren’t. He slowly got himself lower on the bed and moved towards your back. He put his hand on your side and the other slid behind your head, which you automatically lifted. Like it was natural, like it was a habit of yours. He put his chin as close to your ear as he could and whispered:
‘Angel, I’m home’ and he slowly glided his hand up and down the side of you. You didn’t budge. Nothing. Still sound asleep, sweetly unaware of the surprise waiting for you in your own bed. He repeated himself one more time but still nothing. It made him chuckle, it was so endearing that you were just so fast asleep and he was also amused by his own inability to wake you up. He decided kisses surely will be the way to go. He pressed his soft lips on the nook of your neck, and he kept peppering your cheek and neck with them until you finally started moving. You turned around, feeling another person around you and his smell surrounded you. You thought you were dreaming.
‘Joon?!’ you finally got your vision back after it has been blurry for a few seconds.
‘Yes angel, I told you I will see you soon’ his low raspy voice answered you and soon after you saw his gorgeous smile, his dimples on his face and his eyes turned into half moons.
‘Is this a dream?’ you asked him, not really fully believing your luck.
‘Not a dream, im off until Sunday and I will be staying with you until then if that’s okay’ he admitted and peppered another few kisses on your cheek. It was more than okay. You were in a little bit of a shock but once you managed to process the information you jumped on him. You lifted yourself slightly and crawled on top of him, wrapping both of your arms under his back and placing your head on his chest.
‘I’ve missed you so much’ you finally spoke, hearing his heart beating really fast in his chest. You looked up and locked your eyes with his. He smiled again and leaned his head down to reach your lips. And you reached back to him and his soft lips met yours. It started sweet and soft but it very quickly started turning fast. The both of you were yearning for each other for so long and the day has finally come. Neither of you would even come up for air, you would just take quick breaths in between the rushed kisses. You quickly felt him getting excited, as you were still laying on top of him and you were sure he could felt your excitement as well, through your very thin pj bottoms. You broke the kiss and got from him and from the bed.
‘Where are you..?’ he got really confused and instantly felt abandoned, missing you next to him.
‘I need to see you. I want the light on’ you answered, turning the corner light on. Still moody, not as obnoxious light as the top light would have been. You turned around and saw him laying in your bed, in his uniform. The expression on your face changed from excited to in awe. You couldn’t comprehend that he was there, he came home, he came to see you. He woke you up in the middle of the night to see you. You walked back to the bed and sat right next to him. He pulled himself up and was now half sitting with his back to the headboard, following your every move with his eyes.
‘Here I am’ he chuckled and made a funny ‘ta da’ like pose showing himself to you. And you giggled. He was so cute and so adorable yet so insanely hot.
‘Would you mind taking this jacket off? I need to check a theory’ you said with a cheeky smile on your face and he looked puzzled. A theory? Theory of what?
‘Theory of what exactly?’ he asked slowly unbuttoning his jacket. He took his time with it, knowing exactly what he was doing to you. He knew it would drive you crazy, as much as he played such an innocent soul, he knew all the weapons he was carrying.
‘Back theory’ you answered with a smile, as your pupils grew wider and wider, whilst he was working on unbuttoning his jacket. And he finally did, dog tags fell out dangling around his neck on his black undershirt. You spotted them but then you also noticed how they are dangling in front of his now huge chest. He has definitely changed. He is bigger now. Stronger. And your brain couldn’t handle it. You squeezed your eyes closed and opened them again just to make sure you aren’t actually dreaming. He took the jacket off completely, uncovering his really broad shoulders and incredibly buffed arms.
‘Do you want me to..?’ he asked, knowing you will not be able to say no to him continuing stripping for you. The black ROKA t-shirt that was now very tight around his upper body, slowly started rolling up as he kept pulling at the top of it. And with one fast move he pulled it fast, through his head and it landed on the floor. His dog tags still around his neck, now in front of his naked huge chest.
‘FUCK’ you only managed to squeak out when you saw him dropping the shirt on the floor. He was insane. He looked insane. All those pictures you have seen of him recently didn’t give him his justice. He looked even bigger in person than on those photos. You put your hand over your opened mouth and shook your head.
You sat there, feeling your underwear getting wetter and wetter. You could call it an ocean at this point. He got up from the bed and walked all the way around it to get to you. He helped you stand up on the bed and he was still somehow taller than you, even when you were on top of the bed. You bit your lip staring deeply into his eyes and you saw he wasn’t smiling anymore. You have also spotted a tent in his camo trousers. He grabbed you and pulled you to himself and you felt his strong arms around you now. He slowly glided his hand from your knee through your thigh and slipped his hand into your bottoms. He didn’t have to look for it long and his fingers felt the ocean that was currently drowning your cunt.
‘Fuck. Youre so wet’ he whispered into your ear and pulled your bottoms completely down. You unbuckled his belt and unzipped his trousers, slowly pulling them down. And they fell down, stopping briefly at his perky ass but you helped them make their way down. He stood out of them and was now standing in front of you, only in his underwear with a very visible and feelable boner at your service.
He grabbed you, and you wrapped your legs around his hips. He turned away from the bed and pushed you to the wall. He nearly squeezed you at that wall. And started attacking your neck. Your wetness now coating his still hidden away but hard length. You wrapped your arms around him, and started exploring his back. It was rock hard, you could feel the muscles tensing whilst he was holding you and you enjoyed every second of it. You also moved your hands to his shoulders and arms to feel his soft skin and also all the places he grew. To remember it. To keep it in your closest memories. As he kept kissing your neck, he finally slowly put you down, on the floor this time, still pinning you to the wall. And he took both of your wrists into his hands and held them for a second above your head, kissed you aggressively and let go. He lowered himself on his knees and burrier himself in between your legs. Slowly moved on them onto his shoulder and held onto your other leg, slowly kissing your lower belly and reaching the sweet spot. He nudged your clit with his nose and started peppering the entire area with kisses, eventually stopping and slowly licking your folds. Very gently at first, almost like saying a polite hello to your body, acknowledging that he was gone from it for too long. But then he picked up his pace and started circulating around your clit, eventually adding a finger or two and sliding it inside you. You banged your head on the wall and moaned the second you felt his lips on your lower area. Your leg on his shoulder drove you mad but gave him more access. You put both of your hands on his head and let him explore. And be explored and took his time, like a thirsty adventurer who hasn’t been home in weeks. Like his life depended on it. And when he felt like he was finished and your knees started to shake and he was slowly pushing you into an orgasm he stopped.
He pulled himself out of you, smirked and slowly moved you from the wall to the bed. And he pushed you, delicately but he still pushed you on the bed and you fell on your front. He followed you right away and trapped you under the weight of his body. He laid his body on yours, pulled his hard length out of his underwear and aimed it right at your entrance. Slowly slid inside you, grabbing you into his arms and pushing into himself. He kept sliding until he got to your cervix. Balls deep inside you. But he didn’t move, he freezes there. He lets you adjust to him, and when he does he can hear your whimpers and moans. When he feels you relaxed around him he started moving his his hips and he started thrusting into you. And he didn’t take him time, he picked up his pace at the same time kissing your back, up your spine.
‘Joon…’ you whimpered, feeling his huge bulky body on top of yours, thrusting the life in and out of you.
‘Little bit longer angel’ he grunted into your back. He pulled out of you and entered again, really deep, reaching the deepest ends of you. And be picked up the pace again, now ramming into you. Wet skin sounds slapping fills the room, mixed with his grunts and your moaning. And he finally reaches forward with his arm and putting his fingers on top of your clit. That was when you couldn’t hold it anymore. You closed your eyes and pushed your ass higher up almost trying to escape him and your body got flooded with ecstasy. You kept moaning and whining and he wouldn’t stop. He kept going and then be pulled himself up and grabbed your hips and added another thrust or two before he reached his top and painted you inside. Painted you white and kept going for a few more minutes.
Your heavy breathing filled the room and he pulled out, slowly turned you around and placed you on the bed. He cleaned himself up with his black tshirt that was still on the floor and disappeared in the bathroom. He came back with warm towel and he wiped your legs and tummy with it.
After that he moved you slightly to the side and got into bed right next to you. His strong arm wrapped you around and you folded forward laying your head on his chest again.
‘Your back is ridiculously buffed Joonie’ you whispered slowly petting his chest with your palm.
‘There is nothing better to do in that shithole angel’ he murmured back ‘but i also liked the look of your back tonight angel’ he added and put his hand into yours and planted a soft kiss on your forehead.
‘I’m so happy you are here’ you added, you closed your eyes and wrapped yourself around him, dozed off back to sleep.
