aww how cute! ok tags # wall sex, hole slapping (1.4k words, not read over aljdkfd)

jaehyun and taeyong had been dating a while before it was time for taeyong to enlist. as friends, and then as boyfriends, jaehyun was used to 'certain things'. for example, being the taller one, he was used to reaching for items on higher shelves or doing things that required his height. and being the one who diligently spends hours in the gym, jaehyun was also used to doing things for taeyong that required strength. opening jars or lifting things. 

so, despite taeyong being the older one, they definitely had a give and take relationship. and of course, doing these acts of service for his hyung was especially worth it when jaehyun received head pants, hugs, and kisses from his efforts. (whenever the other members were around to witness them being lovey-dovey like this, they'd complain how taeyong was 'babying' jaehyun so much. haechan in particular would sulk and pout, and required at least two members to appease him.)

jaehyun didn't mind. he didn't have any complaints; he was used to their dynamic like this. and when it came to sex, the two were a normal vanilla couple. missionary with the lights on or off. doggystyle. most often in the bedroom, on a bed. normal. vanilla. and jaehyun never asked or requested for anything more...

but that changes when taeyong has a week off for chuseok. when taeyong was dropped off at their shared apartment by a manager, jaehyun gets the shock of his life. his hyung - boba-eyed hyung - who was allergic to working out or doing anything besides practicing music, dance or playing video games really... looked so different. in a good way.

"hyung!" jaehyun wraps his arms around taeyong, laughing and excited and overwhelming relief settled in him. because seeing his boyfriend in real life - and not through FaceTime or text messages - was an amazing feeling. then jaehyun giggles in surprise because suddenly taeyong is squeezing him tight in the hug and lifting him up? with ease! in the process, jaehyun can feel taeyong's muscles flex and...

wow. umm hmm. 

"i've missed you, my jaehyunnie." taeyong says with a smile after they finally break away from each other. jaehyun smiles back at him then his eyes trail along taeyong's form, taking him the full view of him. in his navy uniform and crew hair cut, taeyong looks maturer. he's always been jaehyun's hyung, of course, but now he looks even more manly? not to mention, the increased in muscles.

"missed you, too, hyung." 

if you had asked jaehyun a year if he had any kinks he ever wanted to try with taeyong,  the answer would be 1) yes but taeyong isn't interested or 2) yes but taeyong probably wouldn't be able to.

not super kinky, however, one of those desires was being lifted and fucked against a wall. it wasn't really possible before. but now...

"hyung, you're kinda different now." jaehyun casually slips in as they lazily make-out. he's naked, and taeyong's topless. it's the second day of the holiday. the first day was memorable - sharing meals together and exchanging conversations. their reunion ending with heartfelt tender lovemaking, which jaehyun enjoyed immensely. but he also had other ideas though wasn't sure how to bring them up. 

"different, how, why?" taeyong asks in between kisses. he has no clue what jaehyun is getting at.

jaehyun glides his hands over taeyong's newly built chest and arm muscles. "this and this. like you have muscles now. you're always handsome to me, of course! but i was thinking..."

taeyong's grip on jaehyun's legs tighten and he forces jaehyun's legs to spread more. "thinking about what, baby?"

jaehyun grows more aroused just thinking about what he wants to say. he whispers, blushing, "it's hot. how strong and built you are now, i can't help but to imagine you manhandling me."

"oh?" taeyong has a curious expression. he dives down to capture jaehyun's lips once again. his hands on jaehyun's thighs as he grinds his clothed lower half against jaehyun's bare ass. "like what?"

it takes some coaxing (i.e. taeyong edging jaehyun with his mouth on his dongsaeng's dick) but he gets the answer. one of jaehyun's secret fantasies. and that's how they find themselves like this:

both now naked, leaning against the wall. or more accurately, taeyong holding jaehyun's full body weight, long legs wrapped around taeyong. taeyong uses one hand to guide his dick to jaehyun's lubed hole. he misses the first two times, huffing in embarrassment. then he pushes in. in this position, being held up by taeyong, jaehyun can't make any significant actions. unlike on his hands and knees where he can push his ass back if he's desperate, in this position taeyong is in complete control.

and jaehyun finds that he loves it.

that taeyong completely decides the pace and power and angle, everything. jaehyun's hands on taeyong's shoulders grow sweaty as he burns up from arousal. taeyong is both thrusting into jaehyun's stretched hole, and forcing jaehyun's body down onto his dick. the strength it takes for taeyong to do all of this is impressive. and hot. most importantly hot.

"hyung." jaehyun whines out. red and pink all over. his body is being jostled up and down taeyong's dick, his hair flying up and everywhere.

"this is what you want, right, jaehyunnie?" taeyong grunts. his grip on jaehyun is tight. his focus is split between holding jaehyun up, and fucking into him. he's pretty good at multi-tasking, he'd say. 

jaehyun, through lust-hazed eyes, glances at his hyung's arms and chest and abs. how tense and bulging everything is to hold him up. to fuck him this hard, against the wall. the sweat that trails down taeyong's muscles. how jaehyun's hole is bullied open more and more because of taeyong's hard dick. it's all enticing. he can't help to clench and unclench in the wanton desire of it all.

"it is, it is." jaehyun moans. his head hits the wall as he can't contain himself. he loses it. cums between them, nearly blacks out. or maybe he does. because the next moment, he's being thrown onto the bed. he bounces on the bed. he feels limbless, weak, satiated. 

"you came, but i didn't. so, i'm far from done with you." taeyong says, firm. the most dominant jaehyun's ever heard him in bed before. his dick twitches in interest despite having just orgasmed. 

"i can take it, hyung." jaehyun says, excitedly. genuinely, eager to what taeyong will do next or how he will act. this side of his hyung is new. unexpected. 

"i know you can, baby." taeyong says, softer than a few moments ago. he kneels on the bed, and directs jaehyun to get on his stomach.

jaehyun does so, waiting.

he hears the lube bottle open again then feels more cool lube poured on his ass. down his crack, all over his ass cheeks. the next thing he feels is his ass cheeks being spread and a few harsh taps to his hole.

"fuck, ah." jaehyun yelps. he didn't expect that. then taeyong is soothingly rubbing at his rim, teasing a thumb in before performing the same action. again and again. jaehyun's grabbing a pillow and biting into it, tearing up. but it feels weirdly good when taeyong alternate between slapping his hole and then massaging at the same spot. 

"what a good dongsaeng, you are. my good boy." taeyong cooes. jaehyun's face gets warmer than possible. he wants to be hyung's good boy, always...

and when taeyong pushes inside this time, it's way more intense. jaehyun bites the pillow even after taeyong has fully bottomed out. jaehyun moans into the pillow as taeyong immediately fucks him at a fast, rough pace. drilling jaehyun into the bed with such fervor and force. he leans down, caging jaehyun in, front to back. his full weight against jaehyun, forcing him further into the bed makes jaehyun feel so tiny and small in the best way.

they're both groaning and gasping in pleasure as taeyong thrusts in and out of jaehyun's abused hole, bodies meeting harshly. even the language taeyong uses tonight is different than usual. dirtier, nastier.

jaehyun's drooling into the pillow as his hyung tells him what a good slut he is, and how amazing his hole is. jaehyun can hardly last any longer, with taeyong's filthy mouth and the precise movements against his prostate. again and again, climax building more and more.

"hyung~!!" jaehyun whines as he shakes and cums for the second time. his body goes lax, including his now loosen hole. taeyong grunts out his name, pounding his ass hard enough that the sound of skin slapping against skin fills the room. he bites down on jaehyun's shoulder as he cums, filling jaehyun's ass.
