A/N: For my sister-in-law hannyhan

Ninomiya Kazunari moaned as his ass was violated again and again, his arms went around the sloppy shoulders of the guy that was moving inside of him. Sakumoto Sho the older brother to Sakumoto Jun, Nino’s best friend and ‘Blood’ brother, his and Sho’s relationship wasn’t something that either of them could talk about with Jun. Nino didn’t want to hurt his best friend and Sho didn’t want his little brother to know. They had even promised each other that they wouldn’t do anything when Nino was staying but they couldn’t stop themselves and it made staying around at Jun’s house a lot more fun. He wasn’t even sure why this relationship had started up between them, Sho had always been just Jun’s older brother, the nerdy almost goffer toothed puffy faced moody college student. He was just the guy that had baby sat him and Jun on weekends when their mums had gone to yoga classes and bake sales. Nino hadn’t had any special interest in him until he had been staying over one night a couple of months ago and had caught him masturbating.

“Kazu… Ssh” Sho said stopping his hips and staring down at him. “If you wake Jun… We’re screwed”

“I don’t care move” Nino begged in a whisper, his eyes filling with tears of frustration as he started moving his own hips to get some of the friction back. Sho gave a chuckle rolling his hips while pressing their mouths together and sucking at his lips. Nino clawed at his boyfriends back his legs locking around him as he slowly started thrusting his hips again. A hand slid down his sweaty body and Sho pulled away from the kiss to slip a hand in between them and start palming at his cock as his hips quicken and deepened. Through half closed eyes Nino stared at his lover’s face watching the pleasure filled eyes screwing up as they both got closer to the edge of coming. There was a long drawn out grunt as Sho shuddered his hips snapping forwards and locking as he spilled out his hot cum into the condom. His hand stilled for a few minutes and Nino gave a whine until he started roughly stroking at him again rubbing the slit until Nino came biting his lips hard to stop himself from crying out. Sakurai kissed his face lazily as their bodies calmed down.

“I wish you could stay” Sho whispered as his lips reached his ear and Nino nodded with a sigh he wanted nothing more to curl up against his warm chest and go to sleep but if he wasn’t in Jun’s when his friend woke up there would be questions that neither of them could answer without telling the truth. He shrugged away from him and scrambled to his feet pulling on his PJ’s and handing out of the room stopping dead when he saw Jun standing there his hand half raised to the door. Jun’s eyes moved away from Nino to look at his big brother who was still completely naked.

“Jun…” Sho started with a blush quickly pulling on some boxers

“What the hell is going on?” Jun asked in a hiss and Nino was positive that he was about to faint. Sho was by his side in a second his arm going around his shoulders holding him tightly as he trembled with fear. “You… Two… Are… You’re sleeping with my brother?”

“Jun…” Nino started reaching out to him. Jun pulled away with a hiss

“You’re sick…”

“Jun…” Sho said warningly, his hand moving up and down Nino’s arm while he stared helplessly at his friend. He had expected Jun to act badly, he worshiped Sho and he was the only person on the planet that didn’t realise the older boy had a lot of fails. “This isn’t Kazu’s fault…”

“Kazu?” Jun sneered “Wow you really are close, ne…”

Nino stared at the floor his ears burning as he heard the next words out of his lovers mouth

“Of course we’re close, I’m in love with him… This isn’t too bad, right Jun… Nothing’s changed…”

“Yes it has” He snapped stalking away to his room. Nino sagged against Sho surprised when a sob escaped his throat. Sho held him tightly and carried him back into his bedroom putting him on the bed and stroking his hair gently.

“He’ll come round” Sho said and Nino sighed. Jun really, really loved his brother, in fact Nino had often teased him that he had brother complex there would be no way Jun would ever forgive him for this.

“I wish we had never started this…” He grumbled turning away from Sho and staring at the wall. He could feel the heat of Sho’s hand hovering over his arm but he moved away quickly and Nino knew that the older boy was thinking the same thing. Sho didn’t have any reason to beat himself up though this whole relationship was his fault.

Two Months Ago….

It was about 1am and Nino finished in the bathroom and flushed the toilet, before washing his hands and turning out the light. It was then that he noticed Sho’s light was still on and his door was partially open. At first Nino thought that the older boy was studying for some super hard test or something but then he heard a gasping panting sound and he had crept up to the door and peeked inside his mouth dropping open as he saw Sho with his legs naked and splayed apart, sweat clinging to a surprisingly well built chest. He hand was gripping at his penis stroking himself and rubbing at the tip. Nino stayed hidden out of sight watching him. He decided that he was going to wait until Sho got to the vinegar strokes and then jump out and scare him but as he moved closer to the door he could actually hear what the older boy was moaning, he stopped dead pressed up against the wall his cheeks flushing hotly

“Nino… oh god Nino…Oh yes!”

Nino felt his heart almost burst out of his chest and he crept away again, as quickly and as silently as possible.

 He hadn’t been able to sleep though unable to stop thinking about what he had just seen with the pervert that was dirtying him with his mind. Or at least that was what he had told himself the real reason he was unable to sleep was because every time he closed his eyes he saw Sho’s cock sliding in and out of his hand and his own cock twitched with a strange excitement as he wished that it really was moving in and out of him. He was meant to have been staying the whole weekend but after no sleep and being positive that he wouldn’t be able to look at Sho. The next morning he had pulled a sicky and asked to be taken home, Chouji, Sho and Jun’s mum checked his temperature while Jun started moaning say they were meant to be playing multi player on Halo. Nino apologised with his best ‘I’m really sick’ smile. His smile faded a little when Chouji asked Sho to drive him home.

Sho had nodded giving him a shy toothy smile as he took the keys from his mum. As they were driving through the streets Nino couldn’t stop his eyes as they kept flicking to Sho’s hand, the hand that had been pumping at his cock. He studied the fingers and he slowly started to wonder what it would feel like if that hand would feel like running over him.

“Nino will be okay? Your mum is home right?” Sho asked when they pulled up outside of his house. Nino took a deep breath, he wasn’t sure if his mum would be home she had said something about going to his grandma’s for the day.  He turned to Sho studying his face before asking in a quiet voice

“Sho… Do you want to fuck me?”

“Wh-wh-at?” The older boy stammered and flushed his hand gripping at the steering wheel so tightly it looked painful “W-why w-would you e-even ask th-that Nino?”

“Because I saw you wanking over me last night…” Nino shrugged and if he was being forced to describe Sho’s appearance in that moment he would say it was a mottled picture of shame, horror and confusion, Nino thought he had looked pretty cute though.

“I-I… Um… I…” Sho gasped and stammered unable to even look at him “I’m sorry…”

“So you do want to sleep with me?” Nino asked his cheeks going a bright red when there was a mute tiny nod. His heart thumped against his ribs a few times and suddenly it became difficult to breathe but Nino had to admit that he still couldn’t forget the sight of Sho humping his hand. “I didn’t know you were… Um…Like that… You know um…”

“Don’t tell Jun okay?” Sho asked saying his first completely coherent sentence for a while his eyes finally on him “I promise that I won’t do that again… I’ll do whatever you want just don’t tell Jun… He’s the only guy that doesn’t think I’m a freak…”

“You’ll do anything I ask?” Nino mumbled and there was a quick nod and Nino gave an almost victorious smile as he put his hand over Sho’s the hand that he had seen. Sho looked away from his face going to the small hand that was covering his own and Nino ran his short stubbly finger down one of the more prominent veins that were showing. “Then… I want you to touch me… The way you were touching yourself…”

“Ni-Ni-Nino?” Sho almost screeched pulling his hand away and staring at him. “Do you even know what you’re saying?”

“Yes…So… Will you?” Nino nodded wishing that in this moment Sho didn’t have to treat him like his baby brothers friend.

“Why… What…” Sho said his mouth agape and his eyes bulging and Nino thought he looked a little like a moron,

“I don’t know… I can’t stop thinking about what I saw…I keep imagining your hands on me…” He said angrily. He wasn’t angry with Sho though just with the confused curiosity that he was making him feel

“Nino… You’re just confused…”

“I know I am… But if you don’t do it I’m telling Jun…” Nino mumbled and Sho looked trapped for a few minutes playing with the bridge of his glasses and then very slowly he nodded

“When do you want to…” He asked and Nino celebrated his minor victory saying

“Now… My mum and sister are at my grandma’s…” Sho gave another nodded switching of the engine and taking out the keys. They got out of the car and Nino felt his stomach fluttering with a million butterflies. They went into the silent house and without speaking Nino led him to his bedroom pushing down the picture of him and Jun. Sho was licking his lips nervously and Nino’s heart was thumping against his ribs so hard that he was positive that the older boy would be able to hear it. He slowly tugged off his coat and was about to tug off his trousers when Sho stopped him.

“Nino… Wait… Please… If we’re going to do this… At least let me pretend…Okay?” he said pulling him to his chest. Nino was a little confused about what he meant but soon his chin was being tilted upwards and a shadow fell over his eyes as Sho’s lips were pressed on to his. This was his first kiss and although with Jun he had seen how it was done but actually doing it himself he was a mess and he almost ended up gasping for air when Sho pulled away to laugh at him “You’re meant to breathe through your nose…”

“I know…” He snapped his cheeks flushing when Sho gave a light laugh moving close again. This time Nino took a deep breath before he felt the lips on his again. They felt so soft, gentle and plump against his narrow ones. He was stunned when he felt Sho’s wet tongue swept against his mouth and he parted his lips in a startled gasp and the tongue slipped inside. Nino tried desperately to keep up with the older boy but he was positive that his kiss was lacking. Sho’s kiss wasn’t lacking, it felt amazing better than anything that he could have dreamed of last night.

Sho tugged off Nino’s clothes and pushed him down onto the bed their lips only parting for short sharp gasps of air. Nino’s skin tingled with electricity as Sho’s hands moved over him and his lips and teeth sucked and nibbled at his lips

“You’re better looking than I imagined…” Sho whispered pulling away to sit back on his legs as his eyes and hands started roaming over Nino’s bare chest and stomach. “So beautiful…”

“Shut… Shut up…” Nino blushed and Sho laughed kissing nose and then lips again before kissing his neck and then collar bone

“Do you have any condoms or lube?” Sho asked in a rough panting voice and Nino blinked up at him. Pushing the happy fog from his mind

“Lube?” He asked with confusion, he had heard of lube but he really wasn’t sure what it meant. He was positive that his older sister had some condom. He was surprised about how confident Sho was now.

“We can use baby oil or body lotion, we don’t want to make you sore… And the condom is so you don’t make a mess… When you cum” Sho whispered in his ear and Nino blushed getting to his feet and walking awkwardly to the bathroom, his cock twitching almost painfully. In the cupboard was his mums Johnson’s baby oil in the yellow pot and after getting it he went quickly to his sisters room finding a full pack of condoms at the bottom of her drawer next to her diary. He took the items back to Sakurai gasping when he saw that he was naked on the bed lazily stroking at himself. He watched him from the door way like he had done that night. His tongue darting over his lips as he watched the way Sho’s muscles contracted and twisted with each downward thrust of his hand and Nino was positive his own cock got harder just from watching. He gave a whine and Sho chuckled stopping what he was doing and holding out his hand to him. “Come here…”

Nino swiftly came to the bed and Sho took the items from him and set them on the bed near the pillow before pulling Nino down onto him, laying him with his back against his chest. Nino shivered as he felt the older boys hard penis against his ass. Sho used his own legs to spread Nino’s and gently stroked his thighs his thumb gently brushing against the balls in slow circular movements. The older boy took the baby oil and smeared some on his hand before taking a hold of Nino’s penis and slowly started pumping at him working in a steady rhythm from tip to base, and then back up to tease at the tip. Nino let out a loud gasp as his foreskin was pulled back and a finger was pulled over the tip. “Do you like that?” Sho asked repeating the action when Nino nodded. Sho tool his free hand and began playing with Nino’s balls. His finger moved from the tip and then down the veins before gripping him properly and pumping at him. Nino thrashed around on the bed his back arching against Sho’s chest causing Sho’s penis to rub at his ass. Sho moaned loudly biting at his shoulder. He sucked at his skin his hand moving faster and faster. Pre-cum mixing with the baby oil and Nino wondered for a second why he had need the condom and then there were no thoughts in his mind as it went white as he released in a short steady burst. He flopped forwards panting deeply as his body buzzed.

There wasn’t much time to enjoy the afterglow though because Sho gripped his ass cheeks and pulled them apart and gently rubbed his cock in the crease of his ass the tip probing at his spot startling him a little

“Wh-What… What are…You doing?” He panted twisting his face to look at him. Sho smiled rocking his hips a little the rough skin of his cock rubbing against his passage.

“Don’t you want to go further?” He asked and Nino gulped a little before nodding. He was scared but he trusted Sho. The older boy gently pushed him so he was on his hands and knees in front of him his ass cheeks part slightly. Sho let out a growl two of his fingers going to play with the hole. They smeared the of the baby oil and cum into the creases of his hole before the forefinger pushed into the first joint. Nino shivered at the sensation, it didn’t feel bad but it didn’t feel good either, it just felt strange to have a finger in there. Slowly Sho eased more of his finger inside until the second joint was pressing against him. Now Nino could feel something more so when Sho crocked his finger a little and then twisted it around as he started pushing in all the way to the knuckle. Nino gasped clenching at the bed sheets in front of him as Sho twisted his finger around inside him before pulling out half way and pushing in again “How does that feel?” Sho asked and Nino didn’t know how to answer and he just said

“Weird”

“Good weird or bad weird” Sho asked slamming his finger in again moving in and out at a much faster pace as he continued to finger fuck him with just one finger.

“Nice weird” Nino answered eventually as it became true. The more the finger moved the more he opened up and the better it felt. Sho kissed his left cheek as a reward and Nino was glad that he couldn’t see his face.

“Do you want to try two?” Was the next question asked and Nino nodded slowly. The stretch was a lot more painful this time causing Nino to moan, “Sorry… But you’ll get used to it…” Sho told him as he started twisting and turning the fingers inside him while scissoring him teasing out the tight skin and muscles. Soon Nino did get used to it and he gave a moan of pleasure this time. The affect was electric and he could feel his cock getting hard again. Sho squeezed some more baby oil on to his hand before adding a third finger and slowly finger fucking him. Nino wasn’t sure if he wanted to scream with pleasure or pain but a gurgled sound left his throat as the fingers moved in and out twisting every now and then for good measure. Soon the fingers didn’t feel like they were enough and Nino started to push back on them wanting to feel them in deeper than they were able to go “Do you want me inside you?” Sho asked and Nino nodded frantically though he was displeased when the fingers were removed. There was a rustling behind him and when he turned to look he saw Sho rolling a condom onto his hard member.

Nino looked away when he saw him smearing on some baby oil and clenched his teeth when he felt the tip rubbing against his prepared hole. Sho gripped his left hip holding him steady as he guided his cocked to the hole and Nino screamed as the fat tip was pushed inside. His fingers almost snapped on the bed sheets and he was glad when Sho stopped with only the tip inside. Even with three fingers preparing him he was ready for this, it was too big, too hard he felt that it was going to rip him in two. “Kazu… Kazu are you okay?”

“It… It hurts…” He panted back not caring that Sho was using his first name. Sho stroked his ass and his back while Nino tried his best to adjust to the cock inside of him. He tried to relax his muscles and it must have worked because the burning sensation eased a little and Sho could push more of his penis inside. He took it slow easing out every now and then to add a little more lube and it seem forever before Nino could feel Sakurai’s pelvis against his ass. Again the older boy allowed him time to adjust before slowly starting to rock backwards and forwards his hands gripping at Nino’s hips.

Nino stared down at the bed unable to believe he was actually being fucked by ‘boring Sho’ his best friend’s brother and that he was starting to enjoy it. Sho’s pace quickened as Nino relaxed and Nino found himself pushing back against him enjoying what was happening inside his body. His half hard cock was swinging and expanding and it sprang fully to life when Sho hit something inside him that he never knew existed. Shock waves of pleasure spread out over his body like ripples and he found himself begging Sho to do it again.

Sho was happy to oblige angling his hips to find that spot each and every time. Nino’s brain was exploding with a multitude of colours and his body trembled as he heard Sho gasping

“Oh… God… Oh… Nino…Yes… So… Tight.” over the loud sounds of skin slapping against skin. A hand left one of his hips and reached around to grip at his cock pumping him in the steady rhythm of the thrusts and Nino could feel another orgasm approaching. His head sank down onto the mattress as Sho continued to pump and pound into him. He felt the older boys nail scrape the slit in his cock and he came clenching tightly around the cock in his ass and causing Sho to give a loud grunt and thrust forwards hard one last time as he came inside the condom. Nino grunted as Sho landed on top of him breathing deeply and kissing at the centre of his shoulder blades. He was almost too afraid to look at Sho but when he did he looked like the happiest man on the planet. They hadn’t discussed the change in their relationship after that day but Nino wondered if it really was just curiosity that had made him force Sho into this relationship.

Present Day…

Nino woke slowly, it had been a few days since Jun had found out about him and Sho. Jun still wasn’t speaking to him but he had apologised to Sho Nino wanted to go home but there was nobody in his house he was there for another two weeks while his mum and her boyfriend were on holiday with Jun and Sho’s mum and dad. His eyes were sore from crying for most of the night. Looking at the clock he saw that it was 6.37 but there was no sign of Sho in the bedroom. He rubbed his eyes looking around the bedroom when the door opened.

“Sho…” He said looking up hopefully his breath catching when he saw that it was Jun

“It’s Jun…” Jun mumbled though he didn’t need too and Nino gulped his fingers moving through his hair as he struggled into a seated position looking at his best friend.

“Ju-“ He started not really knowing what he wanted to say. He still wasn’t sure what was going on between him and Sho.

“Shut up…” Jun snapped coming to sit on the bed glaring at him. “Why didn’t you tell me?”

“How would you like me to have said it?” Nino asked finally able to find his tongue.

“’Oh Jun… By the way the only reason I come round is because I’m sleeping with your brother?’ That would have been a nice place to start” Jun said still in his waspish tone and Nino flinched a little.

“That isn’t true…”

“So you’re not just pretending to be my friend so you can sleep with my brother?”

“Of course not” Nino denied quickly as Sho came into the room resting against the wall watching them silently water rolling down his face telling Nino that he had been in the shower. Nino pulled his eyes away from his lover to look back at his friend “I promise… You’re my best friend… This thing with Sho… I don’t know how it started I was just curious…” Jun sighed folding his arms across his chest, looking at them both and Nino could see that he was trying to understand “Jun…”

“Is it still just curiosity?” Jun asked slowly looking back at Nino.

“No… Not anymore…” Nino said looking at Sho and give an embarrassed smile which only increased when Jun clicked his tongue

“You always said he was made of fail!”

“Yeah… He is but…He’s mine” Nino grumbled and Sho tried to offended but the grin that was on face ruined the look. Jun gave a sigh.

“As long as you’re not all creepy lovey dovey over each other all the time… But you have to make sure you look after my brother…” He said and Nino sighed nodding quickly.

“Of course I will”

“I can take care of myself!” Sho protested and both Nino and Jun rolled their eyes together

“You can’t even cook! You have no fashion sense! You trip over your own feet! You only have air muscles…”

“Okay… Okay… Kazu will take care of me!” Sho mumbled putting his hands up as they continued to list his many faults. Nino gave a laugh feeling better than he had done for days. He looked around at Jun who squeezed his hand tightly.

“I’m sorry about how I’ve been acting… I just can’t believe that you didn’t trust me…”

“I’m sorry… Its just you have such a huge brother complex… I thought you would rip my head off” Nino mumbled half truthfully and Jun jabbed his arm painfully with his elbow and Nino gave another laugh as Sho came over to him. Jun rolled his eyes getting to his feet

“I’ll leave you two alone…” He said stopping when Sho hugged him tightly “Nii-chan… Don’t be weird…”

“Sorry” Sho apologised letting him go ruffling patting his head and Jun stared at Nino.

“Are we playing Mario cart later?” he asked and Nino nodded straight away as Sho started playing with his fingers. Jun smiled going out of the room leaving Sho and Nino alone.

“I told you he would come around…” Sho mumbled as soon as he was gone and Nino stared up at him realisation dawning in his mind

“You talked to him” he said and Sho nodded pushing his bangs away from his face and kissing his forehead.

“I told him that I would never forgive him if he made you break up with me…”

“What? You blackmailed him into forgiving me?”

“You blackmailed me into sleeping with you…” Sho reminded him and Nino blushed looking away from him “Because you were curious…”

“Curiosity to love… I love you Sho” He said in a rush and Sho pulled him into a hug kissing him deeply. There were still a few more problems they would have to get through but at least they had each other and Jun on their side. They said that curiosity killed the cat for Nino curiosity brought him the love of his life and he couldn’t be happier.
