A/N : …okay, this fanfic just proved that I'm a pervert. Really.

Summary : Rikuo learned that a drunk Yoru is a pain in the ass…literally. Yoru learned that a drunk Rikuo is a temptation.

Warnings : yaoi sex (of course, for what else you come here?), under-aged drinking, bondage and…well, just read it? XD;; oh, a bit mention from the game of Okami.

Yoru is known for being a drinker. Well, it's not like that is a new thing as a youkai; they all love getting drunk. But Yoru loves sake even more than water, to the point Rikuo getting massive hang-over every morning because of his other self drinking all night long.

No. It's not fair that he's the one who experienced hung-over. Not even his love for the silver haired youkai would make up for it.

So, when Yoru took over his body and getting the famous Thunder Brew sake from Yura, his irritation turned into dread.

And that's why he's now in a tug-of-war with Yoru, with the sake bottle as the rope…

"No! No no no and no!" Rikuo tugged at the slippery bottle of sake as hard as he can, "I'm sick of getting hung-over every morning! You got it easy since you don't feel it, but enough is enough!"

Yoru kept tugging at his precious sake, Thunder Brew sake was rare like seeing pig's flying, so he wouldn't let it slip from his hands that easy, "Let me drink it, just a bit is enough!"

"No! Thunder Brew sake is far stronger than what you usually drink! I don't even want to imagine what kind of hung-over I will get tomorrow!"

"Come on, don't be stingy…" Yoru smirked, "I will even share it with you if you want."

Rikuo huffed, "I'm still thirteen years old, so; no thank you."

Yoru leaned closer to his other self, smirk still evident on his handsome face, "What is age for us, youkai? You never complained when we did other 'mature' things~"

Rikuo's face went red from embarrassment and fury, "I DID complain, but your thick skull never decided to listen!"

The silver haired youkai leaned even closer, their nose almost touching as he whispered teasingly, "Oh, I'm sorry. My ears were busy listening to the sweet sounds of moans and mewls this tempting lips made." He stole a kiss from the flustered Rikuo, who accidentally let go of the sake in his shock. Yoru took the opportunity to opened the lid of the sake and drunk it happily.

"Ah!" Rikuo angrily choked his night self, "YORU!"

Yoru easily swatted away Rikuo's hands from his neck as he drunk the awful tasted liquid (in Rikuo's opinion) more and more, "Wao. Not weird that they called this as the legendary sake that even could intoxicate the mighty Yamata-no-Orochi. It's so strong that my usual sake is like water compared to this."

"Then stop drinking it." Rikuo sighed as he massaged his temple, already feeling the coming headache.

Yoru smirked at his day self, "No way. I just have to drink this way more slowly to avoid being really drunk." The youkai offered Rikuo the bottle, "Do you want some?"

"No." was Rikuo flat-out refusal.

"Too bad then." Yoru resumed his drinking, drinking a small amount at time and savoring the taste of alcohol in his body.

Rikuo sulked as he turned away his body from his night self. Jerk. Stupid, stone-head, insensitive jerk. He wondered how he could fall in love with his night self and how he could tolerate all of his irritating acts so many times. Now he has to endure another hung over tomorrow morning; thankfully, the day after was Sunday. He just hoped that the hung over wouldn't be that bad…

A sudden embrace from behind him snapped him from his sulking. Strong hands snaked around his waist, and he could feel hot breaths on his neck. He could see some strands of silver hair from the edge of his vision. Before Rikuo could say anything, a pair of lips kissed the back of his neck teasingly; which sent shivers along the boy's spine.

"Why…are you sulking?" Yoru giggled, "It makes me feel…bad. Like I…did something bad."

Wait.

What? What did he just hear?

Yoru? Giggling? He never thought that he would see the day when he saw it.

The silver haired youkai snuggled closer to the boy, still giggling like a child, "Aww…come on, don't be so sad… I will share some of the sake with…you too." Then he hiccupped, "…oops, seems like I had too many of sake…tonight? But I'm sure I only drunk a bit…"

Huh?

Rikuo turned his body to face his night self, only to see what he feared come true; Yoru was drunk. And he wouldn't stop that childish giggling…!

"You must stop drinking now, Yoru." Rikuo sighed irritably, "Come on, give it to me." The chocolate eyed boy stretched his arms to take the bottle, but Yoru lift it higher than his short hand could reach, which irritated him further.

"Ah..? Do you want some too…?" Yoru smiled childishly as he beamed, "Okay, will share it!" Yoru took another sip of the sake.

"I said, stop i—" Rikuo's words got stuck on his throat when a pair of lips captured his own in a kiss. Rikuo's eyes widen open in surprise. He tried to shove the taller youkai away, but Yoru put his free hand on the back of Rikuo's head, with his fingers teasingly rubbed the outer shell of Rikuo's sensitive ear, which left the boy moaned in surprise and pleasure.

Rikuo almost choked when liquid trickled down from Yoru's mouth to his. The awful taste of strong alcohol almost gagged him, but Yoru cleverly keep Rikuo's head tilted upwards, making it easier for the liquid to stream down Rikuo's throat. Rikuo winced as it left a burning feeling on his throat and tears prickled down from his eyes. It's unpleasant, like eating wasabi.

Like he's apologizing, Yoru's tongue slipped inside past his day self's lips to lick the remains of the sake. Rikuo moaned when their tongues battling each other for dominance, but even when he's drunk, Yoru still dominated him easily. It's unfair.

When their lips parted, Yoru broke a string of saliva that connected them when he licked his lips, "Rikuo…taste even better with sake…" He leaned closer to the panting boy, "Let me have more…" he repeated the process, though this time, Rikuo swallowed the liquid more easily.

Rikuo groaned at the burning feeling on his tongue and throat, trailing all the way to his stomach. It made him felt so hot and light-headed. He wondered from where he heard that giggling voice, only to be surprised when he found out that he's the one now who's giggling, even though there was nothing to be laughed at.

Yoru smiled sheepishly, a blush appeared on his cheeks as prove of his intoxication, "See? You like it." He gulped the rest of the sake down, no longer caring that he's slowly losing his mind to alcohol.

Rikuo watched with half lidded eyes, how a trickle of that clear liquid trickled past Yoru's open lips. Suddenly, he pouted. His hands trying to reach the bottle, but in his drunken state, he only succeeded in flailing his hands around and knocked the bottle away from Yoru's hand, making the rest of the liquid spilling all over their body and clothes.

Yoru's irritation turned into surprise when he saw Rikuo was pouting at him, "Don't kiss the bottle!" Rikuo leaned closer to Yoru, "Kiss me…" shyly, Rikuo grazed Yoru's lips with his own in a chaste kiss.

Yoru smirked as he deepened the kiss. His tongue licked the remaining taste of alcohol inside Rikuo's mouth. Intoxicating. The taste of Rikuo and sake, it's just too delicious for him. He couldn't help himself from wanting more and more, it's just never enough.

His lips trailed open mouthed kisses to Rikuo's neck, the sake that's spilled on their bodies before has almost evaporated due to their body heats and the scent was heavenly to Yoru's sensitive nose. He licked drops of liquid from Rikuo's neck to his shoulder, tugging at the yukata which was in the way. He wondered why Rikuo is so tasty…? The soft flesh beneath his teeth was just too tempting, and he couldn't resist the urge to bite down at that sun-kissed skin. A soft cry from Rikuo made him shivered in delight.

'Ah, it's bad.' Yoru licked at the mark of his teeth on Rikuo's shoulder sensually, 'I can't control myself…'

As Yoru proceed to lick all the remains of sake from Rikuo's chest, Rikuo moaned softly from the pleasing burn that his night self left on his skin whenever that sinful tongue touched his skin. Rikuo tugged sharply at Yoru's yukata, forcing them open to reveal the pale skin underneath, 'I want to touch him…more and more…'

"Eager, Rikuo…?" Yoru asked breathlessly as he shoved Rikuo gently down to the ground of their dream world. Rikuo was never this…forward on their usual sex. Usually it took a long coaxing and work from Yoru to make Rikuo even dared to touch him like this. To see that lust and adorable pout on his blushing face as he tried to rip his yukata off was too…sexy.

Rikuo pouted cutely at the stubborn knot of obi on his night self's obi, making it hard to undress Yoru from his waist down. Deciding to work with what he have, Rikuo latched his lips and the silver haired youkai shoulder and started to suck and bit on it, leaving many red marks.

Yoru groaned at the pleasure he felt from his day self. He went down lower to Rikuo's stomach and dipped his tongue at his navel, drinking the last drop of liquid pooling there. It made Rikuo mewl satisfyingly, which left the youkai as impatient as the young boy and he ripped away Rikuo's obi, leaving the yukata opened to reveal Rikuo's hard erection.

Rikuo moaned as he could feel Yoru's gaze on him, "Hurry, Yoru." He whispered seductively, "I want to feel you inside me." Rikuo licked his own fingers, purring when he could see Yoru's eyes watching his tongue with undeniable lust. He put his wet fingers on his entrance, stroking it briefly before entering his tight hole, stretching himself open as he moaned pleasantly.

Bless all deity up there, Yoru could feel his erection hardened painfully at the tempting sight of Rikuo's masturbating in front of him. He growled as his hand grabbed Rikuo's hand and yanked it out from his hole. Rikuo hissed in displeasure, but quickly turned into a loud gasp and moans when Yoru entered him in one quick thrust.

"Gah, Rikuo…so tight…" Yoru smirked, "You're clenching me so hard…" he didn't wait too long to move. He slid out of Rikuo, only to slam it harder and harder back inside; creating wet, dirty sound as their flesh met each other. Rikuo moaned, louder and longer every time Rikuo penetrate deep into him, hitting his sweet spot deep inside him.

"Mo-more…" Rikuo breathlessly pleads, "I want more…"

Yoru stopped a bit, his hands lifted Rikuo's thigh to his shoulder, spreading his legs wider and creating new angle which made him able to penetrate as deep as possible. Rikuo cried out, his moans and mewls forming incoherent words of pleasure.

The silver haired youkai found the bottle of sake near Rikuo's head. He reached for it and grinned when he could still find a little of sake inside. But, instead of drinking it, Yoru spilled it over Rikuo's chest, his tongue licking eagerly as it trickled down on Rikuo's skin, mixing with sweat.

Rikuo reached his hands to his night self's neck and encircled his hands there. Understanding the motion, Yoru pulled Rikuo up so the boy straddling was straddling his lap. Rikuo's moans became sweeter and louder as both of them seeking for their climax.

Yoru's free hand took Rikuo's erection and pumped it along with his thrust. Rikuo mewled in pleasure, kissing Yoru's open lips hungrily, as if the boy was devouring him. Their kiss was messy; trails of saliva went down to their chin as they gazed at each other's eyes. Chocolate and crimson orbs filled with lust, passion, and love.

Rikuo closed his eyes tightly and screamed as he came. Yoru gritted his teeth to hold his moans as Rikuo's walls clenching him tightly and he thrust deep inside his day self, shooting cum deep inside Rikuo.

"Waka? Are you alright? You looked like you didn't sleep at all last night." Tsurara's concerned voice called him from his musing.

"Tsurara…quiet down a little, please." Note to self : never drink Thunder Brew sake again. The hung over was so bad, he felt like he's being electrified by thousands thunders. He wished that he could just fainted. He already puked like he's a pregnant woman this morning, and the headache was hammering his head. Every little sound or voices only further agitate him.

Well, the only good thing was that Yoru could feel it too. Rikuo smiled to himself as he could hear Yoru's groaning and complaining in his head. 'Hope that will teach him a lesson,' Rikuo sadistically thought.

Too bad Yoru has already found out that a drunken Rikuo was just so sexy, he didn't mind going through this torture again.

A/N : …what have I done…? XD;; well, it's quite hard to write more since I have lost interest in Nurarihyon no Mago (I haven't read the manga since months ago…) I would need to read it again to gain more inspiration and love it again. But until next time, here it is.

Thunder Brew is the best sake that Kushi, a young maiden from the legend of Yamato-no-Orochi, that could intoxicate the eight-headed serpent so much that Susano, her lover and savior, could beheaded them and rescue her.
