A/N:

Whelp. I'm surprised I made a chapter 2 either. Just to make up for my lack of updates, or ugly chapters from my updates.

I'm not sure if I did this right. It took me MONTHS before completing this, cos I'm busy with my other fics and such.

Warning: YAOI,INCEST,TWINCEST, if you don't like those listed things. Don't read this, I don't want to emotionally scar you for life -at least not yet.

An incredibly long smut (particularly the foreplay I think). You've been warned. WARNED, I say

A few days has already passed since that awkward love-making wherein Kuro was present and made some intriguing comments. The Cat Sith still bothered his master and nagged him to let him see the activity called a 'blow job'. He is very much curious about it.

"Come on Rin! Please? Just one!"

Rin stomped angrily at the corridor heading for cram school. Seriously, he rarely puts it in his mouth because he finds it so embarrassing. Him having Yukio's dick in his mouth while the owner watch him... Rin is not a very shy bottom but it's still a little challenging in his part. Sure Yukio has done it to him several times than he doid to him, but the younger didn't have much difficulty in doing it, he's not as big as Yukio after all. While the older has the harder bargain, the size of his brother is unbelievable.

He remembered the first time he did it... his mouth could only go a bit further half way because he would gag if he tried taking in more. A plus factor for his embarrassment was that... Yukio guided him through it, saying such words... Rin blushed a little remembering it.

Kuro noticed that his master didn't answer and his face is a little flustered with an unreadable expression, "Ne, Rin? Something wrong?"

Snapping out of his thoughts he replied, "Huh? Nothing,"

"Oh good. Will you let me watch?"

"Never!"

"Oi, idiot, why did you bring your cat and why are you yelling at it?" asked an irritated Bon. The half demon didn't notice that he is already in front of his classroom, he shot the older boy a leer,

"None of your business!"

He was only answered by a scoff and returned talking to Shima and Konekomaru. Rin sat at his place beside Shiemi, who is folding origami. Kuro jumped on his desk and sat there facing him,

"Then can you tell me what it tastes like?"

Rin blushed hard, "Wha-! Why do you want to know what it tastes like!" with his rather loud response everyone else in the room turned to him with questioning looks.

"What what tastes like Rin?" Shima grinned perversely at him as he asked

"Uh... the... uhm...the spoiled food I accidentally ate when I was a kid that made me sick that caused me intense diarrhea that haunts me until present time making me swear to check whether the food I will eat is expired or not...?" He shot him his signature grin then turned back to his cat with a dark expression.

Rin stood up and carried his cat by pinching its nape heading to the seat at the far back and corner of the classroom giving them privacy in talking about these matters. His classmates resumed to what they were doing earlier ignoring the half demon remembering that he's weird in his own way at times.

"So why do you want to know?" He whispered to his familiar,

"Just curious." Really, Kuro is just curious. Never could he understand the significance behind such actions.

Rin sighed, perhaps if he explains and answers his questions, he'll be saved from demonstrating, "Well it's part of the body... so it tastes pretty much like the finger only a bit saltier..." He said holding out his index finger. He can't believe he's actually describing such things. But it's definitely better than being watched. (a/n: from the manga I read about this subject, the character said that it tastes like a finger. Don't take my word for it. Just correct me if I'm wrong)

"Aah.. I see. What about that liquid that seeps out of it?" Kuro appreciates that Rin is giving him information, he loves his master so much, he's so nice and kind.

Rin leaned in closer keeping his voice low, "You mean the white stuff?"

"Yeah that and the other one that leaks out even before the orgasm."

"Oh... that's the precum, it leaks out to uh... I don't really know, it just does when it's aroused. The white stuff is the semen, also known as cum, it's the one that comes out in orgasms. What about those?"

"What do they taste like?"

He could feel his face heating up more as this conversation goes on, "...It tastes... salty too, I can't really describe how it actually tastes like,"

"It's alright. Do you like how it tastes?"

"u-uuhh..." Now this is getting dangerous, if he says he likes how it tastes, it makes him sound like a total cockslut, but it would be a lie if he said he hated it, it's the opposite actually. Yukio's taste is very much addicting to him, "..I-it's okay..." He replied coolly with a shrug.

Kuro just stared at him, "So why do you do it?"

Rin flinched, "I...ahm..because it feels good for Yukio...a-and I want him to feel good sooo...I do it... a-and it feels good for me to...in a sense.." For the half demon, this conversation feels like one of those question and answer portion in the pageants people watch on T.V. wherein the contestant is clearly nervous. But of course, it's not like they'll ask questions like these, if they did, then that would be one hell of a contest that Rin would enjoy watching while he laughs at those dolled up contestants.

"And also because you love him that's why you want him to feel good?"

"Yes." Well that's nicer reason. "Are we done with that interrogations now?"

"Hmm... yeah I guess... but only because Yukio is already here." Kuro said hopping down from the desk to the floor and striding out of the room. Rin blushed looking in front of the classroom and found Yukio standing there giving him a slightly annoyed look, probably because he wasn't paying attention yet again, "Okumura-kun. Stay after class." Yukio ordered,

Rin gulped, "Yes sensei."

As their classes with Okumura-sensei went on, Rin couldn't help but thought about certain things, things that he shouldn't be thinking this time around as it made him look at the lower half of their young teacher's body. 'How long has it been since I...?' His thoughts was cut when the other student are already leaving the classroom. He scowled, it took him over an hour just thinking about those things? Seriously, Yukio's closet perversion is rubbing on to him.

Rin stood up and as he was about to leave the classroom he heard his brother from behind, particularly at the teacher's table, clear his throat reminding him that he was in trouble...again. The half demon sighed and closed the door, then an idea hit him. Turning to his younger twin sitting at the teacher's chair facing him with arms crossed and that stern look, he locked the door behind him and strode lazily to his awaiting doom, though he's pretty sure this will turn out very well...

And Kuro's nowhere in sight! Life is good.

"Nii-san, how many times do I have to tell you to pay attention in class? And you even brought Kuro. Honestly, you'll never be an exorcist anytime soon with such attitude towards your studies." said Yukio clearly unhappy. Rin made a conscious attempt to not roll his eyes at his brother's nagging.

"I do try you know. I'm just not as diligent as you are."

"Make it more convincing that you do try." The young exorcist pushed up his glasses as he closed his eyes briefly then motioned to stand up only to be pushed back to his seat by the older twin. "Nii-san. Stop messing around." he scowled up at him

Rin smirked, "I'm not." he replied simply then stepped towards his brother and straddled him. Yukio could catch on what's going to happen and returned the smirk.

"Distracting me in this way will not get you out of trouble, nii-san."

"Aww... you thought I'm gonna distract you? What if I tell you that I just want to do it?" Rin said as he wrapped his arms around the younger's neck, held him close and pressed their bodies together.

"That would mean you're a very naughty boy who needs discipline."

"Hmm~ Don't I always get in trouble?" The half demon no longer waited for a reply and kissed Yukio. The younger quickly turned the simple kiss into a fiery one when he pulled back slightly and tilted his head, angling it to a better place and slid his tongue effortlessly in Rin's mouth roughly and was greeted by the latter's tongue. Together, both wet muscles slid and wrapped each other. Yukio traveled his hand from the small of Rin's back to his ass and grabbed them earning him a delicious gasp from the older,

Rin moaned feeling weak from the dominance, he really couldn't win against Yukio. Feeling that recognizable hard tent he's seated on, he pulled away from the kiss - his quick motion cut the string of saliva and dribbled on his chin. He removed himself from his brother's lap and knelt between his legs.

"Don't tell me you're..."

"I haven't tasted you in a while." He nuzzled his cheek on to the other's growing arousal still confined in his pants. The action made its owner release another groan, "Can I?" Rin looked up at him then licked the tent formed in Yukio's pants then sucked under it teasingly,

"Make sure you'll do good" Yukio's smart enough to not let this opportunity pass. After all, it's as rare as a blue moon when Rin would agree to do a blow job, and here he was knee bent in front of him asking permission if he could suck him. Adorable.

Rin unbuttoned and pulled down the zipper then tugged the pants along with the boxer and revealed the fully erect member. He then wondered again if this was a great idea when he saw the size up close. Gulping his small fear, he held the base with one hand using the other to lever himself steady by placing it on Yukio's inner thigh.

He dragged his tongue from the base to the tip then pushed his tongue gently on the slit earning himself a low moan from his brother. He licked the length again this time from the side, recognizing the addicting taste, he moved his mouth to the tip and kissed it and then engulfed the head. He sucked on it slowly yet hard while his tongue flicked from the inside to teasingly lap the tip. His saliva oozed from his shallowly filled mouth and reached his hand that was on the base, using the liquid as a lube, he began to pump the shaft as his mouth crept further swallowing the length and stopped halfway. Rin moved his head up and down in time with his hand.

Yukio could feel the pleasure rolled in his stomach and throughout his body. He grabbed Rin's head and pulled it further down his length signalling him for more of his hot mouth. The latter complied and moved his head down slowly, testing if he could still take it completely because it's been a while since he's done this - an estimate of a few months. A little further he gagged, he haven't even swallowed it whole yet, but he knew that there's a chance that he could, since his done it a few times.

"Ah..Rin..."

Rin responded with a hard suck then withdrew his mouth from the shaft and licked from the base to the tip again. Swirling his tongue around the head, he relaxed his mouth then in one quick motion, he downed the shaft whole making Yukio gasp as a sudden extreme pleasure overtook him. After a few seconds, the hot mouth began moving up and down his length, taking him whole.

The hand which Yukio held on to Rin's head, massaged the navy locks' scalp fondly as the older kept sucking him. Rin could feel tears well up in his eyes as the head of the dick repeatedly hit the back of his throat but the hand caressing his head told him that he's doing a pretty good job so it's all worth it. Yukio watched as Rin moved his head up and down - his length going in and out, in and out of that mouth. It took all of his will power to not thrust his hips and fuck that mouth. He closed his eyes and sighed in pleasure,

Rin could feel the organ get larger and larger in his mouth, signalling the close release. He kept his pace then stopped as he buried his mouth on the whole shaft and sucked hard making the younger come with a grunt. Hot sticky fluid rushed out of the organ and into his mouth. Semen also landed on his face as his head was slightly pushed back by his younger twin

"Open wide, nii-san." Yukio instructed in a playful tone. Rin opened his mouth catching his cum as Yukio pumped his dick ejaculating last spurts of his orgasm, seeing Rin with a heavy blush, his mouth wide open, tongue slightly darted out, blue eyes dazed and darkened with lust; he ended with a pleasured sigh. Using the tip of his cock, he dragged the semen that was almost dripping to Rin's chin and back to his mouth, the older twin gave one last suck and he swallowed it and panted trying to catch his breath.

After regaining his composure, Rin stood and flashed Yukio his signature grin. "Was that enough to forgive me, sensei?" Though, his confidence suddenly deflated when the other male smirked that smirk which only meant bad news.

"Hmm...Not really, I'll still punish you later on..." His smirk grew when he saw Rin pout, "But since you were so good with what you did, let me return the favor."

"Eh?! N-no! You don't have to- ugh!" Rin's plea was denied when his younger brother pinned him on the teacher's table and loomed over him with a smile, of course. "We can't do it here!"

"Why not?" Yukio asked in a low husky tone as he proceeded to lick Rin's neck; sucking and biting all the while making the older pant. He took of his tie and used it to bind the smaller's wrist atop his blue head.

"Because...we'll...m-make a mess! Ah~!"

"Says the boy who downed me until I came all over his face." He unbuttoned Rin's dress shirt leaving trails of kisses on every measure of newly exposed skin. After he undid the buttons and opened the shirt revealing that flawless white skin he stood up, took off his nii-san's belt, tugged off his pants along his boxers as he completely ignored the whining of the latter, little did the older know that his cries and pleas were a great turn on. Once his done undressing him, he smirked down at his older brother. Rin, who was no longer able to retaliate with his wrists bound leaving him at the mercy of his sadistic brother, lied on top of the heavy wooden teacher's desk, his chest heaved panting heavily from arousal. Teal eyes trailed down looking at his obvious hard on with precum oozing from the tip trailing lower and lower...

"Yukioooo!" Rin whined once again feeling all the more annoyed, albeit embarrassed, when his thighs were grabbed and pushed up and apart exposing everything he has to hide.

Said man licked his lips with the sight of his twin's pink hole, looking needy, and wet from the precum that leaked from the head of his dick. "Are you sure that you don't want me now? 'Cause this little thing here says otherwise..."

"Ngh~! I-I...ah..I just wanted to suck you...!...haa.." Try as he might, Rin couldn't help the moans escaping his lips when he felt a finger teasingly rub the rim of his hole. He tried to swat the hand away with his tail but it was a futile attempt since the long black appendage was following his bodily pleasure which resulted it to wrapped around the exorcist's arm pulling it closer and do more.

"Did you really think that I wouldn't take that as an invitation?" He began teasing his hole by shallowly prodding it making the latter whimper involuntarily from the unending torture. Hearing such adorable constricted sounds, the younger jammed his finger in suddenly and made Rin gasp as he closed his eyes tight savoring the feeling of a finger probing his inside. Then he let out a sigh as another finger was added and then the last digit went in sooner than the earlier ones.

By now, the half demon was nothing more than a pile of whimpering and moaning bundle of nerves as his sweet spot was constantly hit. Yukio stared at his older twin's face immersed in pleasure, the way his brows furrowed upwards with eyes closed, his mouth open with a trail of saliva on the corner as he let out those hot sounds, and that undeniably beautiful deep blush adoring his cheeks. Oh how the younger teen was so turned on, just the sight of Rin's flawless white legs as he wore black knee-high socks was enough to set fire to his nether regions. Truly, his brother's a demon for being so alluring even without trying.

Rin moaned louder when his younger half began toying one of his nipples with his other hand, his body started quivering uncontrollably from the pleasure. He can no longer play hard to get and wanted to get it on with already,

"Hnngh...ahh...Put it in now, sensei~" His needy and wanton way of calling 'sensei' made his arousal grow full on. The larger male pounced on the smaller and attacked his lips again as he aligned his member on the eagerly waiting opening. The rough assault made Rin gasped granting the other permission to shove his tongue and engaging in another immoral kiss.

'Ne ne! Yukio's thing really is big, ne?!'

Rin's eyes shot open. Just when he thought his sexual nightmare would never happen again...

"Oh, I also had a hunch that Okumura-sensei would be large, I just didn't imagine it'd be that large. I'm impressed." (A/N: I notice that I keep mentioning and highlighting his manhood, is it weird?) Peculiar, another voice was heard. Does the half-demon dare to look up? But his brain doesn't allow him to think of things for too long, so he broke the delicious kiss, which made his lover attack his neck, and he tilted his upwards to see if his fear was real. And indeed! Only this time, it's worse.

There sitting idly by the end of the classroom sat a black cat and a small white dog with a pink bow around his neck. And we all know who those are: Kuro and Mephisto. Rin's face became stunningly red, it became even more flushed when he felt the thick press of his brother's member on his hole, "W-wait!" He pushed on his shoulder to stop his advances,

"Alright...? But you know, it's really hard to wait when i'm already in the process of doing it."

"I know! I know! It's just that... look!" Rin pointed at the two animal demon perpetrators. Yukio arched a brow feigning indifference,

"So?"

"I'm not gonna let you do anything unless they're out of here!"

The taller man sighed, "Do I look like I can restrain myself any longer?"

"Oh Okumura-sensei, you need not to stop yourself~ Don't mind Kuro and I, we're just here to learn about the process of life~" Mephisto said as he waved a paw. "By the way, I'm also impressed with Rin-kun, he can take that size?"

"Of course he can! Rin practices with this!" The aforementioned half-demon screamed like a little girl when Kuro brought out a certain very personal item of his. Mephisto and Yukio's eyes widened when they saw it.

"Amazing! I didn't think Rin-kun would have something like that! How lewd! Is that an extra large?" Mephisto inquired still in awe.

"I dunno; I just see Rin putting this in his butt and pleasuring himself whenever he's alone in their room." Kuro replied nonchalantly.

"You stupid cat! You were snooping around the windows again?!" The cat's master angrily blurted out. His familiar only nodded quite happily at him.

Yukio looked back at Rin, his expression blank yet obviously curious, "I didn't know you have a dildo."

The blue-eyed stuttered, "I-i-it's not wha-what it looks like! I'm not perverted! Shima just gave it to me as a prank gift...! A-and I was bored one time s-so I tried it...! It felt really good so I've been using it to masturbate...sometimes...!" He tried to defend his honor.

And the domestic-pet-looking duo kept bickering on about the twin's sex life, while Yukio proceeded back on sucking, licking, and kissing Rin's neck distracting the older a bit yet it wasn't enough to block out the once again embarrassing conversation revolving around him and his sexual exploits.

"Rin looks really cute when he's about to orgasm, he looks like a needy kitty."

"Really~? I would love to see that~"

"You'll get to see that now! Yukio looks unstoppable."

"Make them stop!" Rin whined.

Yukio rolled his eyes at the two audience completely uncaring whether they're there or not and turned back to Rin, who was giving him a look that made him think twice - the half-demon was scowling and pouting at him with a very noticeable blush and eyes on the verge of crying. He sighed and looked back at the white dog and black cat with a strong glare, "Oi. Get your furry selves out of here or I'll skin you both alive."

"Heh! You don't scare us, Yukio~!"

Of course Yukio didn't understand what Kuro said and looked at Rin asking for translation, "He said he's not scared of you."

He smiled at the Cat Sidhe, "Oh but I don't need you to be scared for me to kill you now, do I?"

"And how are you going to kill us now with your obvious need for release?" Mephisto said slyly.

"I'll rape you both and then after that I'll impale your violated little bodies on the fence by the sidewalk so everyone will see." Yukio told them with his expression menacing; and then he smiled at them, "Won't that be fun? Want to get started?"

"No!"

"N-no need to be brutal, Okumura-sensei... we were just kidding, right Kuro? Ahem, w-we'll leave you too alone. Tata for now~" And the two small critters made there way out via Mephisto's amazing puff of pink smoke.

Rin sighed in relief when the duo was gone, "Thanks..."

"No problem, though those two are real mood killers." Yukio kissed his older twins jawline leaving butterfly kisses from his neck down to the smaller's chest.

"Yeah." He looked away shyly

The younger chuckled lowly and gave a nipple a little lick making the other whimper, "Don't worry, you're so delicious-looking that I won't get turned off."

Rin clasped his hand onto the latter's cheek and lead him back to a heated kiss, "Mhm... yeah, that's a perv for ya..." He opened his mouth once again letting the other roam his tongue in his warm and wet cavern.

Yukio smirked and parted the kiss for a while, "Next time, let me watch you play with your toy."

"NEVER!"

END

I'm sorry I didn't give the complete intercourse... it would be way too long if I did. Besides, I guessed you guys must've been already so bored by this. THAT and I can't write the process well; I was nervous. I MIGHT make a third chapter. MIGHT. If fate would be so kind for me to get inspired.
