Mod note: In case you're wondering about the underage sex, Yunho is 24 and Jaejoong is 16.

Yunho got out of his car and stretched.

‘Nothing like coming back home for Christmas.’

He started walking towards his house and unlocked the door, but just when he was about to open it, the door swung open.

“Goodness Yunho…you scared me! I thought you were spending Christmas with your friends?” Yunho’s Umma said.

“Well yea…but I decided to spend Christmas with my family instead,” Yunho smiled.

“I’m sorry sweetie, your Appa and I are going on a second honeymoon this year…and we’re going to miss our flight if we don’t hurry and leave.”

Yunho was stunned, “Bu-but Umma! I haven’t seen you guys all year!”

“Don’t worry Sweetie, Jaejoong is still here, which is perfect because now he won’t be alone for the holiday’s! It’s a good thing you came back.” Umma quickly put her suitcases in the trunk.

“Well at least I won’t be alone…” Grumbled Yunho.

“Oh hey Yunho! No time to talk! Jaejoong is sleeping right now, anyways we got to go now, bye and take care of everything while we’re away!” Appa quickly put the rest of the suitcases in the car and he and Umma waved their goodbye’s as they left.

“…..Seriously…my parents suck!” Yunho brought his bags into the house and went straight to his room.

‘Hmm…well my stuff is now in my room, and I’m kind of hungry…I wonder if Jaejoong won’t mind making me something to eat…his cooking is just as good if not better then Umma’s cooking.’, Yunho decided as he opened Jaejoong’s door instead of knocking first.

“Jaejoong I was-” Yunho’s eyes nearly bulged out when he saw a woman standing inside of his little brother’s room.

The woman had long blonde hair and she was wearing a tight short dress, revealing her long luscious pale legs. The woman quickly turned around and her eyes widened when she saw Yunho standing at the door.

‘Wow she’s really hot…wait…she kind of looks like…oh god…’

“J-Jaejoong…?” Yunho stared in disbelief.

Jaejoong blinked cutely, “Hi Hyung…didn’t know you were here…but now that you are…What do you think of this dress? It looks really good on me…doesn’t it?” Jaejoong smirked at Yunho.

“Y..Yah! Why are you wearing a dress? Wait…are you a cross-dresser?! Anyways…get out of that…and um make me something to eat…I’m kind of hungry…and please wear anything but that!” Yunho sputtered as he quickly closed the door and ran down the stairs to the kitchen.

Yunho clutched his racing heart, his thoughts flying wild like on a crazy rollercoaster ride.

‘OH MY GOD! I can’t believe…he would wear a dress…though the dress suits him very well…AH don’t think that Yunho…he’s your little brother! Aish..’

Yunho made himself a cup of coffee and sat at the dining table, and started reading the newspaper. Jaejoong closed his door and smirked as he made his way to the kitchen. Jaejoong has always been attracted to his older brother and now that their parents were gone, he figured that now would be the perfect time to get into Yunho’s pants. Literally.

“Hello Hyung! Sorry about earlier, what would you like to eat?” Jaejoong started rummaging in the fridge while smirking.

“Oh I don’t know, wha-” spits out coffee “YAH! WHEN I SAID WEAR ANYTHING I DIDN’T MEAN COME DOWN HERE NAKED IN JUST AN APRON!” Yunho’s eyes bulged out of his head as he dropped the newspaper on the tiled floor.

“You didn’t say I couldn’t be naked Hyung…” Jaejoong sat on Yunho’s lap and looked up at him seductively.

Yunho was frozen, he didn’t know what to do, so he sat there gaping at his little brother.

Jaejoong slowly lifted his hand and started to rub Yunho’s chest, he licked his lips very slowly as he continued to rub Yunho’s chest and abdomen with his long slick fingers. Yunho sat there in shock, while he slowly started to get turned on by the rubbing against his hot body and the way Jaejoong continuously kept on licking his red plump lips.

Their phone started ringing suddenly, as Yunho came out of his stupor and quickly got up, accidentally dropping Jaejoong on the floor with a soft thud, before rushing to the phone and answering it.

‘Ouch…that hurt…pabo Hyung!’ Jaejoong thought bitterly as he slowly got up and rubbed his bare ass a bit.

“Um Jaejoong…it’s for you, some guy named…um Yoochun,” Yunho said as he held out the phone for Jaejoong to take.

‘PERFECT!’ Jaejoong eyes lit up as he took the phone, “Yoochun! I’m so happy you called! Do you know how much I miss you? It’s so sad that your family is going on vacation! I’m going to miss your sexy body and that sexy voice of yours.” Jaejoong said in a flirty tone.

Yunho watched Jaejoong in confusion, ‘Wait…is that Jaejoong’s boyfriend?’ Yunho frowned and felt a tinge of sadness and jealousy as he watched his brother talking to this so called hot-and-sexy-boyfriend Yoochun.

“Um…what? Jaejoong why are you talking like that? You know Junsu won’t appreciate you talking to me like that….I thought you liked your Hyung?” Yoochun said in a confused voice.

“Yes, but he’s watching me, so I have to put up a show!” Jaejoong whispered, “Do you miss me too, baby?” He cooed louder the moment he noticed Yunho’s eyes watching his every move.

“Ah I see, alright talk away then, this is actually quite entertaining.” Yoochun said amusedly.

‘What the fuck!’ Yunho thought bitterly as he glared at the smiling and giggling Jaejoong clinging onto the phone.

“Phone sex? Aww I’m sorry Chun-Bun, but my Hyung is here…later?” Jaejoong smirked quickly when he saw Yunho’s jealous expression.

‘WHAT!’ Yunho clenched his fists in anger, he didn’t understand why he was feeling like this, earlier he felt repulsed about fucking his brother, but now he really wanted to fuck him senseless.

“Ohhh, you want to see me one last time before you go on vacation? You naughty boy…I think we should meet at our secret place before you go off, we haven’t fucked in a while.” Jaejoong said seductively.

‘Shit…my old feelings are returning…I knew it was a bad idea to come home for the holiday’s!’ Yunho growled low in his throat and quickly grabbed the phone out of Jaejoong’s hand, “I’m sorry but Jaejoong is really busy and cannot see you, and he’s taken by someone else.” Yunho hung up the phone before Yoochun could reply.

Jaejoong grinned in victory but quickly changed his expression to anger, “YAH! How dare you tell my boyfriend I’m taken by someone else! You’re going to give him the wrong idea! Aish, now I have to call him back to clear up this misunderstanding.” Jaejoong was about the grab the phone again, but was suddenly pushed against the wall by a pair of strong arms.

Yunho growled low in his throat, “You will not call him back, weren’t you the one who wanted to be fucked by me?” Yunho asked huskily.

“What gave you that idea?” Jaejoong replied innocently.

Yunho scowled, “Don’t pretend to be innocent now…” Yunho placed one of his hands on Jaejoong’s face and yanked Jaejoong’s face upward to look him in the eye. “I know what you want.” Yunho started to attack Jaejoong’s lips, sucking, nipping and biting on the boy’s delicious lips.

Jaejoong opened his mouth so Yunho could fully taste his sweet vanilla flavor. Jaejoong moaned into Yunho’s mouth as the man’s tongue tasted every inch of his mouth thoroughly.

Yunho stopped for a second so they could both take a breath. “Upstairs. NOW!” Yunho growled as he picked up Jaejoong as quickly as possible and practically ran to his room, kicking his door open, before throwing Jaejoong onto his bed.

“Don’t regret this after I’m done with you…” Yunho ripped Jaejoong’s apron off as he scanned Jaejoong’s entire body, licking his lips with a lustful look in his eyes. Jaejoong started getting hard only by the way Yunho was practically eating his exposed body.

“It’s only fair if you also take your clothes off…Hyung..” Jaejoong licked his lips as he started to take off Yunho’s shirt.

Yunho smirked and ripped his own shirt off while pushing Jaejoong down onto the bed. “Don’t worry about that, I’ll do it myself.” Yunho quickly slid his pants and boxers off as well.

Jaejoong’s eyes widened when he saw how big Yunho was, his dick was almost a foot long and five inches thick. “Like what you see?” Yunho said huskily as he started to attack Jaejoong’s mouth again.

Jaejoong wrapped his arms around Yunho’s neck as they were kissing hard and passionately. Yunho started kissing downwards to Jaejoong’s neck, he began sucking and biting, leaving many love marks all over the younger one’s chest and collar bone.

“This is going to hurt…so scream as loud as you want…and dig your nails into my back…” Yunho said softly while smirking.

Jaejoong gripped onto Yunho’s shoulders and tried to calm himself but before he could fully relax, Yunho shoved his dick into Jaejoong’s tight hole without any preparation.

Jaejoong screamed as loud as he could, as he had never felt that kind of pain before. He started to cry as he dug his nails into Yunho’s back. Yunho grunted and moaned as he started to pound into Jaejoong, He would have never guessed that Jaejoong would be so tight and warm as it felt simply amazing around his cock.

“Relax baby…” Yunho grunted as he continued to slam into Jaejoong.

“..H-hurts…” Jaejoong whimpered out as he dug his nails down Yunho’s back.

Yunho changed the angle of his thrusts, looking for one certain spot that would drive his little brother insane.

Jaejoong gasped, he never felt that sensation before, “T-there Yunnie!”

Yunho smirked as he continued to hit Jaejoong’s sweet spot, making the latter forget his pain and start to feel pleasure.

Yunho continued to mercilessly pound into the younger boy, hitting his prostate every time Jaejoong was mewling and moaning loudly, forgetting about the pain he had experienced at first.

Yunho growled and started attacking Jaejoong’s nipples, biting, sucking and tweaking them as he fucked the sweet young teenager under him with increasing passion.

“AHH…ahh…YUNNIE…I’m…GETTING..s-so…CLOSE…” Jaejoong screamed, while arching his back as he could feel his abdomen tightening and pooling, singling how close he was getting to his release.

“Wait…let’s cum together…” Yunho thrustd as fast and hard as he could, feeling close to his release as well.

Yunho pulled the samller boy’s hair and gave him a searing hot kiss as they both started to reach their climax together. Jaejoong moaned loudly into Yunho’s mouth as his cum shot out and covered them both. Yunho also released at the same time as his cum started to fill up his brother’s hole.

They broke apart, trying to catch their breath as their high from their orgasms started to wear off.

Yunho looked down and frowned when he noticed cum and blood covering Jaejoong’s thighs. ‘Weird…wait…’

“Jaejoong….you’re a virgin…aren’t you?” Yunho glared at his little sixteen year old brother.

Jaejoong smirked, “You really think I wasn’t?”

“That guy isn’t your boyfriend…”

“I knew my Hyung was smart, I just waited for you to figure it out yourself.” Jaejoong held an innocent look.

“I should punish you, but since I already did…I’ll let it slid this once, but we aren’t done here.” Yunho smirked.

Yunho slowly pulled out of Jaejoong and noticed him wincing slightly as he moved to the side of the bed and flipped Jaejoong onto his stomach.

Jaejoong blinked in confusion, he looked at his Hyung waiting for his next move.

“Get ready Jae…” Yunho whispered huskily into Jaejoong’s ear, causing the smaller man to shiver in anticipation.

Yunho opened one of his drawers and pulled out a tube of lube. Jaejoong glared at him when he saw what the older man held.

Yunho just grinned, “I forgot about it, you made me jealous and angry, I wanted to punish you at first.” Yunho opened the tube with a soft pop and squeezed some of the lubricant onto his fingers.

“Don’t worry, I’ll go slow this time.” Yunho said has he placed a soft kiss on Jaejoong’s lips.

Yunho slowly slid a finger inside of Jaejoong, waiting for the boy to relax and get used to the intrusion. As the smaller boy fully relaxed, Yunho started to move the digit in and out of his dongaseng at a slow pace.

Jaejoong whimpered, indicating that the one finger wasn’t enough, so Yunho slid another finger in, scissoring them as he pushed them in and out.

Jaejoong pushed back onto the digits, wanting more than just two fingers. Yunho smirked and slid yet another finger in, stretching Jaejoong even more. It amazed Yunho how Jaejoong can become tight right after having sex with him a few minutes ago.

Yunho brushed the boy’s prostate and he let out a loud moan. Yunho licked Jaejoong’s earlobe as he slid in another finger into him. Jaejoong gasped and held onto the pillow tightly, he felt a little uncomfortable until his Hyung touched his pleasure spot.

“Ahh…Yunnie….mmm…” Jaejoong bit down on his bottom lip, trying to keep quiet so he wouldn’t feed Yunho’s lust.

Yunho smirked, before skipping the next step as he slowly eased his fist into Jaejoong’s clenching hole.
Jaejoong’s eyes widened at the huge intrusion, bursting into tears, the burning feeling returning from before when Yunho first took him.

“Shh baby…it’s okay, just relax your body, don’t think about it.” Yunho tried to comfort Jaejoong while rubbing the smaller boy’s lower back with his other hand.

Taking deep breaths, Jaejoong started to relax his entire body, starting to get used to Yunho’s fist deep in his tight ass.
Yunho noticed Jaejoong’s relaxed form and slid his fist out, then pushed it back in at a slow pace. Yunho continued to thrust his fist in and out slowly, making sure to brush against the boy’s magical spot.

“Ahhh…feels…good…weird…ahh….more..” Yunho started speeding up his thrusts, moving in and out quicker while brushing against Jaejoong’s g-spot each time.

Yunho quickened his pace, thrusting harder each time, getting extremely hard while Jaejoong continued to moan nonstop.

“Yunnie…AHHH YUNHOOO!” Jaejoong screamed out as he came a second time that day.

Yunho slowly eased his fist out, enjoying the view of Jaejoong writhing and panting, trying to catch his breath.

“My turn, time to put that mouth of yours to good use.”

Jaejoong turned over and rolled on top of Yunho and kissed him senseless.

“Don’t worry Hyung…I’ll make sure to make you feel real good.” Jaejoong licked his lips seductively as he made his way towards Yunho’s hard shaft.

Jaejoong gave a small lick at the tip, tasting the salty pre-cum of Yunho. Jaejoong started to lick slowly from the base up towards the head, swirling his tongue around the head.

Yunho grunted, “Tease…”, while Jaejoong simply smirked and slowly let the man’s entire head into his mouth, giving one hard long suck.

“More!” Yunho moaned loudly, demanding for more of that sinful mouth around his cock.

Jaejoong gladly obliged and put as much of Yunho’s cock into his mouth as he could, relaxing his throat so he could deep-throat him.

Jaejoong bobbed his head up and down, licking Yunho’s shaft with slow teasing moves as he sucked the older boy dry. Yunho moaned, loving the feel of the younger boy’s mouth around his erection.

Jaejoong started to speed up his pace, gently biting down on the tip every once in a while, as one of his hands continued fondling Yunho’s balls gently. Giving squeezes now and then, Jaejoong felt himself hardening as he started to stroke himself at the pace he was sucking Yunho. Jaejoong moaned, sending sensational vibrations throughout Yunho’s cock, making the older man reach his climax soon.

“Fuck…you’re so good Jae…” Yunho moaned loudly, while Jaejoong only smirked and continued with his sucking, trying to go as fast as he could, sucking as hard as he could while pumping himself.

Jaejoong used his other hand and started pumping the base of Yunho’s dick that couldn’t fit in his mouth.

“Shit…so good…close…” Yunho groaned out.

Yunho could feel himself getting closer to his release, it took one last pump, suck and moan from Jaejoong to send him over the edge.

“AH JAE!” Yunho moaned loudly as he came into Jaejoong’s mouth, the boy made one final pump of his own as his seed shot out onto the bed.

Jaejoong swallowed as much as he could of what Yunho was offering him, licking his lips to get any remaining love liquids from his Hyung, enjoying the taste of bitter salt.

Jaejoong’s mouth felt really sore, along with his ass as he lied next to Yunho, trying his best to catch his breath.

Yunho got out of bed to retrieve a wet cloth to clean up the mess the two brothers made.

Yunho gently wiped Jaejoong’s stomach and thighs, cleaning up the dried up cum and blood of the younger boy’s pale body. Yunho also started to clean himself, before finally throwing the dirty cloth into the laundry basket in his room.

Yunho lied down next to Jaejoong, bringing the covers over them and pulling his dongsaeng close to him.

Jaejoong snuggled into Yunho’s chest, “Um…Yunho…” he whispered.

“Yes Jae?” Yunho replied softly.

“I…I love you…I have for a while now…ever since three years ago...” Jaejoong shyly looked up to see Yunho’s expression.

Yunho blinked then looked down to see Jaejoong looking nervous, shy, nothing but true love reflected from his big doe eyes.

Yunho smiled, “I love you too….for three years, that’s why I went to a school far away, I didn’t want to hurt my adorable cute not so innocent brother, I didn’t want to taint you with this sin.”

Jaejoong smiled also, “Well now you know you have nothing to worry about, because I’m all yours and will always be yours no matter what.”

“Good, because I don’t plan on letting you go, ever.” Yunho kissed Jaejoong on the boy’s plump cherry lips, the kiss full of pure love.

“Um…what should we tell Umma and Appa?”

Yunho smirked, “Nothing, we leave it as it is.”

Jaejoong blinked in confusion, “Huh?”

Yunho chuckled, “A secret between brothers.”

Loved it! Even if I'm not comfortable with the incest idea. It woul've been better if they were not blood related, I guess.
Anyway, it's a good fic and if it is YunJae, everything goes...
