**Insatiable Eighteen**

Chapter Two

"Goku's my baby brother."

Sanzo loosen his silk tie and unbuttoned the first two buttons on his shirt. His first destination was the kitchen. He grabbed a can of beer and slowly made his way up the stairs. As he passed Goku's room, light music could be heard even with the door tightly shut. He wondered for the millionth time since he came back from England why does the boy like this type of music so much? Weren't teenagers supposed to listen to hard rock?

Sanzo's room was just next to Goku's. And the condition of its room was the opposite of Goku's room. His bed was neat and made up properly, there wasn't a speck of dust found in the room. His working desk was empty except for a few stationeries. And his bookshelves were packed neatly with thick encyclopedias.

Placing his cold canned beer on his table, Sanzo flung himself onto his bed. His thoughts somehow stuck on the boy. Son Goku, which Sanzo was certain sleeping like a log now, was actually an adopted kid.

Flashback

Great, he was finally free from those two men. Believe him, spending five years watching Hakkai and Gojyo turn from friends to lovers wasn't exactly appetizing. And after five years of his useless University life, he finally comes back home. It was HIS home. He had moved out and quit staying with his parents since college.

He hardly noticed the soft snoring sound as he walked through the living room. His eyes almost popped out of their sockets when he saw a young boy sleeping on the couch. To make matters worse, the boy was wearing nothing but a pair of blue boxers.

After a hard time of waking the boy up and asking for some good explanation, Sanzo rubbed his temple to ease the headache. He gave a call to his parents to confirm if the brat was telling the truth. His parents, who were in Canada working, confirmed that Sanzo now officially has a baby brother popped up from nowhere.

Sanzo placed the phone down, his laser glare landed on the 'brother' he was supposed to take care of. He just can't believe how much his life sucks. Well, taking care of his adopted brother was slightly better than his five years of tortures. He could live with it.

To his utter horror, Hakkai and Gojyo moved in next door the next day. Goku had quickly won over the two men's hearts with his innocent looks and cheery smile. Sanzo, Hakkai and Gojyo raised a questioning eyebrow when Goku said he was eighteen. It was hard for them to believe.

So it wasn't that bad since Sanzo was starting his work the next day. So he guessed he wouldn't have time to bother with those three weirdoes. But then once again, life is a bitch. Hakkai and Gojyo turned out to be his colleague. Even his 'brother' happens to be a student in that school! Coincidence? He doubts that.

End of Flashback

Well, that's that. Like it or not, he's got an adorable, cute, sexy and innocent eighteen year old teenage boy living with him as a baby brother, and his neighbors are gays.

Sanzo sat up lazily and snatched his towel from the chair, his beer ignored. Looking at the new and unused towel, he grumbled slightly. Goku had given this to him as a gift a few days ago. A towel from Goku I can understand that, but a towel with steaming meat buns designs??

He entered the bathroom. And then he suddenly remembered Goku and his rooms have connecting bathroom. There was another door from the bathroom that leads to Goku's room. Sanzo had the sudden desire to try if the door to Goku's room is unlocked. He snapped out of his weird thoughts and proceeds to peel off his shirt.

~*~

The door creaked open.  Who's that? Goku tried to pry his eyes open but his eyelids seemed to be glued together. Soft footsteps were making its way towards his bed. Damn it! Answer me, who's there? He panicked as he felt someone's breath caressing his cheek. W-who's there?!

"Goku." Upon hearing his name was like a curse lifted. Goku's golden orbs stared directly at Sanzo's perfect feature. Why was his heart pounding so fast in his ribcage all of a sudden? Maybe it had something to do with Sanzo being half-naked. Or was it because of Sanzo's smile? Okay, he admit it, he was going crazy with Sanzo's delicate finger running down his bare chest. "You like me …" It was a statement, not a question.

Goku swallowed his saliva. How did Sanzo know? He never told anyone about his little secret. It was pure confusion that made Goku raise his hand, his eyes never leaving Sanzo's violet ones. He timidly touched Sanzo's blond hair. When Goku was sure he did not angered the beautiful man, his fingers started to lightly run through Sanzo's hair. "I like your smile." Please, don't stop smiling.

It was his little secret. Although he understands Sanzo was his brother but lately, the blond-haired man had become more than a brother to him. He was Goku's sun. He was something Goku wanted but could never have.

"I know what you want." Goku wondered what Sanzo meant when he said that. His thoughts were frozen at the soft texture of Sanzo's lips pressing on his. At that moment, right that second, Goku could have died with no regrets. Shutting his eyes to let himself drown in the pool of pleasure Sanzo's lips provided, Goku sighed in blissfulness. Goku's hands somehow did their job by pushing the back of Sanzo's head, forcing the elder man to kiss with more brutal strength.

~*~

And that's when Goku snapped his eyes open to realize Sanzo wasn't there anymore. It was a dream. It took a while for him to get used to his depress and disappointment mood. That was such a realistic dream! Goku shook his head lightly, embarrass that he had mistook a pillow for Sanzo.

He was troubled of this dream he had been having frequently. Of how Sanzo would come to his bedside, how Sanzo would touch and tease him. How Sanzo would kiss him. Argh! Sanzo is my brother! I do NOT kiss brothers and I do NOT have wet dreams with males!! Especially with my brother!!

Yeah, and the lower part of Goku's body says something else. It is NOT my fault that my big brother happens to be a young, stunning, oh-so-hot and beautiful man!! He looked at his wristwatch and groaned as he had slept too long, it was almost dinnertime. Goku hopped out of bed, careful not to step on his school bag or other sharp accessories that happens to be on the floor as he walked across the room. He softly hummed with the music and dropped his boxers on top of his school uniform, which was also on the floor. He opened the door to the bathroom.

And he saw his big brother inside the bathroom fully naked. Sanzo and Goku exchanged stoned looks. Ten seconds has gone by when Goku finally turned and calmly walked out the bathroom as if nothing unusual happened. He shuts the door with a slight 'click' before leaning his bare back against it. A weird grin formed on the boy's face.

"GOKU!!!!!!!!!!!!!!!!!!!!!!"

~*~

He watches with big innocent eyes at the man who was washing the dishes. Dinner was held in an eerie and silent atmosphere. Goku tried to ease up the intense mood by talking. But it was either he gets no reply or only the walls, tables and chairs were listening to him. Needs no genius to figure out Sanzo was giving him the cold shoulder.

What a touchy brother… "Ne, Sanzo?" Goku called out for the nth time. As expected, no respond was given. Goku frowned. Sure he would love to piss Sanzo off once in a while and gets the cold shoulder but it was different this time! He didn't did it on purpose when he opened the bathroom door to see Sanzo butt-nak… You get the idea.

He should have been smart enough to lock the door. Goku thought about pointing out this simple fact to Sanzo, but he guess the stubborn man just wouldn't listen. "What is wrong with you? Brothers accidentally running into each other naked is normal all the time." It seemed to work as Sanzo paused his activity and then turning back to send Goku a dirty look. "It was an accident and I'm sorry if it bothers you that much."

"But you've seen my…" Sanzo almost bit his tongue and he left the words hanging in the air. Shit, why am I even talking to him?! He turned back to resume the washing. He was pretty annoyed when the bubbly baby brother of his appeared beside him. "Get lost." He snarled.

"Sanzo…" Goku pouted and frowned cutely. It was hard for Sanzo to stay mad with him. "I wasn't the only taking advantage, you saw mine too!!" Sanzo takes back his decision about not staying mad at Goku. He was about to take his paper fan out for some action but stopped himself as Goku stared teary eyes at him. "I'm sorry. Please forgive me."

Goku doesn't like it. He doesn't like it when Sanzo ignored him. It made him felt… unwanted and abandoned. He swears he was going to cry if Sanzo continues to treat him as an invisible boy. "Fine, we're even." Sanzo said quietly. If it meant that forgiving the boy could stop him from looking so pitiful, Sanzo might as well be generous to do so.

Sanzo relaxed a little when Goku smiled again. "Can I help you dry the dishes?" He asked his big brother in enthusiast. Sanzo arched his eyebrow at his request. Normally, Goku wouldn't be eager to volunteer himself for any housework. 

"Suite yourself." Goku grabbed a dry towel, waiting for Sanzo to pass him the dishes. With one hand holding a dish under the soapy water, Sanzo held out his other hand to pass a sparkly, gleaming wet dish to Goku.

Was it another 'accident' when Goku's fingers slide against Sanzo's wet, slick ones as he reached out to take the small round plate? Sanzo, in his normal reaction, let go of the plate immediately to draw his hand back. Goku, on the other hand, did not have a firm grip on the plate. They gaped helplessly as the plate dropped onto the kitchen floor, breaking into a few pieces.

"Fuck." Sanzo muttered. He crouched, using his hands to pick up the bits of broken plates. Why was he acting like a total klutz in front of his baby brother? He had broken far more cups and chinaware back when he had Hakkai and Gojyo as roomies. It was never a problem, Hakkai was always there to do cleaning up. But now, Sanzo had to clean up his own mess. Lucky Gojyo. Has Hakkai all to himself.

"Wait! Sanzo, you shouldn't use your…" Before Goku could finish, Sanzo yelped and cursed loudly. His index finger had a long gash, blood oozing out of the fresh wound. "Shit, it looks pretty bad! I'll go get a band-aid for you." Little did Goku knew, his matured ways had greatly annoyed Sanzo. Who's the big brother here now?

"Forget it. I'm not a little kid like you." Sanzo said stubbornly. He placed his wounded finger in his mouth and tasted his blood. No, he never did this before and thinks it is ridiculous. But he saw Gojyo doing this to Hakkai's wounded finger once and he didn't want Goku's 'pity'.

"Don't do that, it's not hygienic." Coming back with a band-aid in his hand, Goku took Sanzo's hand and brought it under the tap, letting cold-water wash Sanzo's wounded finger. Years of being alone and independent taught the boy daily common sense. Sanzo kept his temper and allowed Goku to plaster his finger with the band-aid. Goku pushed Sanzo out into the living room, mentioning for him to go and have a rest.

"Are you sure you can finish up the rest of the dishes yourself?" Sanzo asked worriedly. He did not hope to see ALL of the plates broken into bits the next morning! Who knows how careless can the boy be since Sanzo barely sees him doing housework?

"Aw…are you worried about me, big brother?" The boy asked teasingly even when he knows Sanzo just meant to criticize him. He brought Sanzo's plastered finger up to his lips and gave it a light peck. Ha! Fell in my trap again! Goku grinned at Sanzo's stoned face. "Since I have to do the dishes I guess we won't be doing it tonight, dearest brother of mine." He ran back into the kitchen in full speed and locked the door. Before long, the thrashing and banging of Sanzo's fists on the door could be heard.

Goku chuckled. Sanzo must have done something wrong in his earlier life. He easily ignored the crazy blond outside the kitchen and resumed washing the dishes. THAT or Sanzo had been very mean to me in our earlier life. Like whacking me on the head with a paper-fan or trying to shoot me with a spirit-ascending gun…Goku paused suddenly. He then shook his head and smiled at that ridiculous thought. Yeah right.

"The only thing I'm doing tonight is MURDERING you, baka saru!!!!!!!"
