(See the end of the work for more notes.)

Work Text:

If you asked Sakuya who his favorite person in the world is, he would say his older brother. If you asked him who his best friend is, he would say his older brother. No matter what type of situation you propose, Sakuya would mention his brother. He doesn’t think there’s anyone in the world who is as kind as Yushi, as funny or handsome, or anyone who treats Sakuya better. 

In fact, if they weren’t brothers, people might even think that Saku has a little crush on Yushi, but that’s not it, of course. He just really likes him. 

Lately, though, Sakuya had started to notice something different in himself. Sometimes when he looked at his older brother, he would get this big, warm feeling in his chest. His heart would beat a little faster, and it almost felt like his lips were itching, itching to kiss Yushi. 

Once, Saku just couldn’t hold back, and he actually jumped into his brother's lap, which was met with a look of confusion from the older. Before he got a chance to speak, Sakuya planted a big, wet kiss on his lips and ran off. If he had stayed behind to see his brother’s reaction, he wouldn't have been able to miss the way Yushi’s eyes grew to twice their size, and his cheeks were colored just the faintest hue of pink. 

After that, Sakuya started experiencing other things that he couldn’t explain. When Yushi would not come home right away after school ended or when he would ask their mother to go over to his friend’s house, Saku would feel… sad? He wasn’t sure, but it didn’t feel good. He would miss his brother every second that he wasn’t with him, and he refused to talk to anyone or play with his toys when Yushi wasn’t home. He would just sit quietly in a corner, waiting for his brother.

And when he finally did come back, Saku would be over the moon, running to greet him at the door with a big hug and an ‘Oniichan, Saku missed you!’ Yushi would always be delighted to receive such a warm welcome, and he found his little brother to be so incredibly cute like this. 

However, the thing that would forever change their relationship happened on a completely regular day. Yushi was just coming out of the shower, opting for no towel as he headed back into their shared bedroom. He didn’t think much of it, the two of them had always taken baths together, and when it came to Saku, he didn’t really feel uncomfortable being naked. 

His brother was sitting cross-legged on his bed, playing some game, when Yushi came in. Saku only glanced at him but quickly did a double-take when he realized he wasn’t wearing anything. There were droplets of water still clinging to Yushi’s skin, running from his shoulders down his arms and from his collarbone, down his chest and stomach all the way to-

Saku shakes his head. He has seen his brother naked so many times before. He doesn’t know why this time feels different. His cheeks are heating up as he sneakily examines Yushi’s body, his shoulders are so broad even though he’s only 13, and the thing hanging between his legs looks heavy. It’s big, a lot bigger than Saku’s own, and as the young boy continues to stare at it, something happens.

He starts to feel warm, uncomfortable in his clothes, and his pants suddenly sit too tight. He furrows his eyebrows in confusion as he looks down at his lap. In his shorts, he can see… Well, he actually has no idea what it is he’s looking at, it’s like there’s something strange inside of them. Usually it’s flat down there, but now there’s a small bump. As if he were to take his fist and hide it inside his boxers. 

Curiously, Saku snakes a hand down in his lap and pokes at the bulge. It draws a hiss out of him, it’s hard and feels funny when he touches it. Yushi doesn’t seem to have heard him as he continues to rummage through his drawers, looking for clean clothes. 

The younger boy pokes at his bulge again, and his jaw falls slack. It’s good, and he wants to feel it again. This time he uses his palm to press down on it just to see what happens. He lets out a loud gasp that doesn’t go unnoticed by his brother. Yushi whips his head around and stares at his brother, his eyes almost bulging out of their sockets. 


“Saku! What are you doing?!” He shrieks and quickly brings his hands up to his face to cover his eyes as Saku sits up straight in his bed. He doesn’t say anything, practically freezes as he looks at his brother. Is Yushi mad at him? He doesn’t understand why. Did he do something wrong? There’s a weird feeling in his chest, and his bottom lip starts quivering as tears pool in his eyes. 

“Oniichan, Saku is sorry. It’s just… something started feeling weird in my pants, and I don’t know what to do.”


Yushi can practically hear the pout as his brother speaks, and he slowly brings his hands back down again. The boy is no longer touching himself, just fiddling with his fingers as he stares down at the sheets under him. Yushi feels bad, of course, Sakuya doesn’t understand that touching your private parts should only be done in private. But Yushi does, they had started talking about it a little bit in school. He was still unsure about a lot of it, though. 

He sighs and walks up to the bed to sit down next to his brother. 


“I’m sorry, Saku. I shouldn’t have yelled at you.” 

He wraps an arm around his brother and pulls him into a tight embrace. 

“That weird feeling is just your body changing. It’s nothing bad, don’t worry! Is this the first time you’ve felt that?” 

Sakuya sniffles as he burrows his face into Yushi’s neck, giving the tiniest little nod. It makes Yushi chuckle as he feels endeared. 

“I see. The same thing happened to me a few years ago. It means you’re becoming a big boy!” 
Saku lifts his head and looks his brother in the eyes. 

“I am? Like Yuu-nii?” His face practically lights up as he takes in his brother’s words. Even with this, there’s nothing he wants more than to be like Yushi. Yushi doesn’t understand why his little brother looks up to him so much, but he finds it incredibly flattering. 

“Yes, baby. Just like me.”


The younger boy is practically beaming at this point, and Yushi feels a strange sense of pride about the fact that it’s because of him. But shortly after, the bright smile on Sakuya’s lips is erased, and in its place a frown comes over his face. He looks shy in a way that Yushi has never seen him before, as he realizes his ‘problem’ hasn’t exactly gone away yet.


“But… what do I do about this?” He points at his still hard bulge as he avoids eye contact. 
“Can you help me? It’s starting to hurt.”


Yushi opens his mouth to speak, but nothing comes out. What is he supposed to say? He knows what you can do, he knows what he himself usually does, but he doesn’t think his brother will understand if he tells him to jerk off. Yushi puffs his cheeks in concentration as he thinks about it. Technically, an older boy showed him what to do when it first happened to Yushi, so wouldn’t it be okay for Yushi, in turn, to show Saku? It sure seems like the better option, with the alternative being Saku possibly being left alone to deal with it and ending up in so much pain that he won’t dare to try again for years. Yushi doesn’t want that. 


“Okay, Saku. I will show you what to do, but just this once. So the next time it happens, you can take care of it yourself, okay?” 

The younger boy nods eagerly as he waits for Yushi to help him. He has absolutely no clue what will come next. 

“Take your clothes off. It’s easier if you’re fully naked.” 


The younger quickly obliges, hopping off the bed to strip before sitting back down as his brother kneels on the mattress. It just now occurs to Yushi that he is still naked, never having gotten the chance to put some clothes on as he caught his baby brother red-handed. Oh well, this will probably go very fast, he tells himself. 

As Sakuya settles back on the bed, Yushi carefully shoves at his shoulder to make him lie down, and settles in between his legs.
Lying in this position makes Sakuya feel shy, they're so close now, and Yushi is staring at him. The heat radiating off of him finds its way into Saku's skin, and it's all a little too much for him. 
He brings his hands up to his face but only gets halfway there before there's a tight grip around them, and his hands are brought to rest above his head. 


“You need to pay attention, okay? You did ask me for help after all.” 


That soft voice mixed with the suggestive position they're currently in does something to him. Yushi hovers above him, their faces close together, with Saku's hands pinned down to the bed, making that heat in his lower belly grow and feel tighter. 

Saku whines and nods, keeping his hands still as Yushi sits upright again. Soft caresses on Saku's thighs make the hair on his neck stand up, and he finds himself spreading his legs even wider. He just needs the painful tightness in his crotch to go away before he starts crying.


“Keep your eyes on me the whole time.” 


And those were the last words Sakuya got to hear before there was a feather-light touch making its way from his thigh up to his stomach, drawing circles on his skin before slowly inching closer to the source of his pain. 

His dick was incredibly small. As Yushi looked at it for the first time, he bit his lip to hide a smile when the word ‘cute’ popped into his head. What? He tried to shake that thought away, of course, his brother's naked penis wasn't cute. He needed to get it together.

He took a breath as he finally let his fingers wrap around Saku's erection. The reaction was immediate. Sakuya's breath stuttered, and he hissed at the touch. 

Yushi let his thumb play around the tip of the penis where some wetness glistened in the light. Sakuya didn't know where that came from, but it felt really good. When Yushi had spread the precum, he wrapped his hand tightly around the shaft and gave a quick jerk. 

It pulled the air right out of Saku, and a loud whine slipped past his lips. 


“Mmh, oniichan, that feels really good.” 


Saku looked up at Yushi with his big eyes as the older gave him another jerk, slowly this time, and then one more. On the third, Saku bucks his hips and somehow manages to make contact with Yushi's own crotch.

It makes the other yelp in surprise and loosen his grip while Saku chases the feeling again, the friction felt even better than Yushi's hand.


“N-no, Saku. Don't do that.” 


Yushi's face is on fire, and he can't look his brother in the eyes. The sudden graze of Sakuya's dick against his own made the blood rush to Yushi's crotch. He wasn't turned on before, just a little tense, but he's a teenager after all. It doesn't take much for him to get hard, which is exactly what's starting to happen right now.

His pulse is speeding up, and he feels a little sweaty, but he doesn't know what to do next. ‘Luckily’ for him, his brother speaks before he gets a chance to spiral.


“Yuu-nii… Yours is going up too. Did it feel good when we touched?” 

Yushi's mouth is agape, he didn't expect his brother to be so forward. However, he is literally butt naked in front of him, and Saku isn't stupid, so there's no point in denying anything. 

“...Yes, Saku. It felt good, but we're supposed to focus on you, not me.” 

He still refuses to look his brother in the eyes, basically talking to the wall instead.

“But. We can feel good together, that's better, isn't it?” 


And before Yushi gets a chance to reply, to most likely say no, they shouldn't, Saku moves again. 

He scoots down to get as close as possible to Yushi, pulling on his arms so he'll hover above him again. Yushi isn't prepared to resist, which is why he easily follows, and when they're positioned properly, according to Sakuya, he smiles.

He snakes his arms over Yushi's shoulders, interlocking them around his neck before moving carefully. 
He lifts his hips to meet Yushi's, the skin to skin contact making Saku squeeze his eyes shut. Yushi really is so much bigger than him, it's hard and warm, almost pounding, and Sakuya presses his crotch against it. 

It draws a moan out of Yushi, he furrows his eyebrows as he looks down at the younger. They shouldn't be doing this, but he can't back out now. 
Yushi moves one hand to Sakuya's hip, pressing it down to still him. A frown comes over the younger's lips, he assumes his brother is denying him any more, but quickly realizes he's wrong. 

Yushi grinds his hips down against him, rutting against his brother. Their cocks slide against each other, with precum now leaking out of Yushi too, making it all messy and weird, but he's never felt this good before. 

Saku gasps again and can't do anything other than just take it as his brother lets the hand on his hip move to where their skin meets. 
He grabs a tight hold of both of them, playing with Saku's slit again before he jerks his hips forward. 


“AH- Yushi, it feels strange. My belly…” 

Saku gazes up at him with a look Yushi has never seen before. Eyes half-lidded, forehead wet with sweat, and cheeks flushed a deep pink. He almost looks sexy like this, and Yushi hates himself for even coming up with that thought. 

“It's okay, baby. You feel good, right?” 

Saku nods frantically at the question, he's never felt better in his whole life. Not even when he got to redecorate his room in all pink and plushies did he feel this good. 

“I think, Mmfh- Something is coming out!” 


Those words make Yushi pick up his pace, going faster because he knows what's next, and he wants his brother to know just how good you can really feel. Yushi is close too, jerking off by himself never felt like this. He's a boy, so it's not like he could do this with a friend, and girls never interested him. Maybe, just maybe, him catching Saku was a good thing. 

He squeezes his grip around them, and oh my god, that's all Saku needed. He screams out as a clear liquid shoots out of his dick. It's not a lot, but it comes out in waves, and Saku goes all soft as he babbles something incoherent about his niichan being so helpful. 

The image in front of him is too much, and it makes Yushi cum as well. White ropes spurt out of him and land right on Saku's chest. The younger gasps as he feels the warm liquid hitting his skin, and then he smiles.


“Saku made Yuu-nii feel good too!” 

He pulls Yushi to his chest, enveloping him in a warm, tight embrace. They're both fully soft again and exhausted. Yushi lets himself get comfortable against Saku's neck, and it doesn't take long before they drift off to sleep. 



When Sakuya wakes up the next morning, his bed is empty, and there's no sign of his big brother. He rubs his eyes as he sits up, and right as he's about to call for Yushi, their bedroom door opens. 

Saku turns towards the sound and smiles as he's greeted by the sight of his brother, his hair is messy, and you can still see the sleepiness in his eyes. Tired eyes that widen as they meet Saku's own.


“Oh! You're awake! You were really tired, so I didn't want to wake you.” 

He rubs his neck as he stands there awkwardly. He doesn't really know how to act after what they did, and he really hopes his brother isn't uncomfortable with him now. 

“It’s true, I got really tired after. But I feel good now! Thank you for helping me, oniichan.” 

Saku giggles and hops out of bed to wrap his arms around Yushi. The older feels the tension drain out of his body and quickly melts into the embrace. 

“No worries. But uh…” 

He trails off as he draws away from Saku and looks down at his naked chest. There's dried and stale cum painting his skin, and the sight makes Yushi blush.

“You should probably take a shower, right? I'm sorry for dirtying you.” 


Yushi chuckles nervously as he finally looks his brother in the eyes. He's met with a smile that could make anyone feel like they just won the lottery, and it makes his own lips perk up.
Saku nods and turns to his dresser to pick out some clean clothes. As he walks towards the bathroom, Yushi remembers something and calls out to him.


“By the way, it's probably best if you don't tell anyone about yesterday… What we did is something that usually only adults should do, you know.” 

He glances at his brother as he turns around to respond, slightly nervous about what he will say. He wrings his fingers as he waits to hear Saku speak.

“Of course! It's our secret. Besides, if I told someone how my niichan made me feel so good by playing with me, maybe they would want to try too. And I don't want to share you with anyone.”


With that, he turns back around and walks into the bathroom, leaving Yushi… confused? At a loss for words? His face burning up in embarrassment. 
So Sakuya doesn't want to share him? Yushi doesn't know how to feel about that. In a way, it's incredibly sweet. Of course, Yushi knows how much his brother looks up to him, and he's always loved that. But on the other hand… 

He shakes his head to clear his mind. It doesn't matter! Yushi had told him that this would only happen once, and it had. Now Saku knows how to take care of it by himself, so he won't need Yushi's help anymore. Problem solved! 

And Yushi feels relieved about that. He does! If there is possibly a very tiny portion of him that feels something more like disappointment, he doesn't acknowledge it. He was being a good brother, and that's it.

When Sakuya comes out again, they talk like normal, and there's no mention of what happened the night before. Yushi figures it really is done with and decides to just stop thinking about it, moving on with his day.

And everything really seems fine, for a week maybe. But then Yushi notices these small things that Saku starts doing. Like ogling his body, being clingier than usual, and always wanting physical touch. 

He would randomly ask Yushi if they could “play together again” when they were with other people. To everyone around them, it seemed like nothing more than a boy wanting to hang out with his older brother, but Yushi knew what he meant. 

Something about Saku's tone when he said it and how he would get up close in his face sent a shiver down Yushi's spine, there was nothing innocent about that question. 
Still, Yushi didn't confront him. It's not like Sakuya had actually done anything that Yushi could prove meant what he thought it did. It was just a very strong gut feeling after all.

It didn't take long for that to change, though. When Saku felt like his advances weren't successful, he took it a step further. He would take any opportunity he could find to plant himself in his brother's lap. 

That in itself is innocent enough, sure. But not so much when he'd start moving his hips, grinding onto Yushi's lap to get him worked up. It worked, of course. It never took much for Yushi to get hard, especially not when it came to Sakuya.
But he always tried to stop it, grabbing onto his brother to make him stop moving. Weakly getting out a few words about how they're not playing with each other anymore through gritted teeth. 

Saku would pout and hop off, but the sight of his Yuu-nii struggling as the bulge in his pants pounded always made the younger proud. Despite his words, it was clear that Yushi couldn't help being affected by him.

Soon enough, Sakuya's futile attempts to get Yushi to touch him came to a halt, and the older found himself relieved but also slightly disappointed. Yes, maybe he was actually starting to like the fact that his brother couldn't stay away from him. 
But he knew this was for the better. He felt like he could take a breath now. Maybe Sakuya had grown tired of him now. Oh, how wrong he was. 

The reason Sakuya had backed off wasn't that he had given up or grown bored. No, quite the opposite, actually. He figured he'd give it one more try, making it a big one this time. 

Whenever he had the time, and some privacy, he would go on the internet to do some research. It wasn't hard to find what he was looking for. In fact, he very quickly found exactly what he needed to go through with his plan, and from there it was just a matter of time and patience. 

While Yushi had noticed that Saku's advances had stopped, he also couldn't help but pay attention to the fact that his brother seemed much happier lately. 

He was in a great mood all the time, always so smiley and almost giddy. Yushi had no idea what the reason behind it was, he felt a little jealous. His brother hadn't been as clingy and desperate for his attention lately, and it kind of hurt. Yushi missed it. Luckily for him, he wouldn't have to miss it much longer. 

It had been three weeks since Sakuya had stopped teasing Yushi, that time being spent getting himself ready for his plan. And he finally was. Now it was all about timing. 

When their parents told them they would be gone overnight, Yushi was big enough to take care of himself and his brother, Saku knew this was the perfect opportunity. They would have the whole house to themselves, so no one could disturb them. He was so excited he could hardly contain himself, but he still did his best. He wanted to surprise his brother.

Soon enough, their parents said their goodbyes and left. Saku watched as they drove off before he decided it was time.

Yushi was currently in the bathroom as Saku sprinted into their bedroom to go through with the plan. He stripped naked and positioned himself on Yushi's bed, legs spread wide open as he waited for his brother to come back.

It didn't take long before their bedroom door swung open and a loud gasp could be heard through the whole house. Saku smirked. Here we go. 


“Saku… What are you doing?” 

Yushi sighed. So maybe he wasn't done after all. His little brother whined and grabbed hold of his dick, giving it a dry rub. It was slightly painful but also really good, and Saku could see the look in his brother's eyes darken.

“Yuu-nii, play with me, please.” 


When he didn't get a response, he tightened his fist over his cock, making himself hiss. He brought his other hand up to his mouth, sticking two fingers in to get them wet. He let his tongue play with them, all while still keeping eye contact with Yushi. 

The older's jaw was tense, and his fists were tightly clenched. The scene in front of him was unbelievable, and Yushi didn't know where Sakuya got all this confidence from. But it was intoxicating, and Yushi was about two seconds away from jumping him, his pants already painfully tight.

When Saku slipped his fingers out of his mouth and let them drag down towards his hole, circling the rim, that's when Yushi finally snapped. 
Before Sakuya could even register what happened, his brother was straddling him, both his wrists now caught in a tight grip and positioned above his head, just like last time. 

His heart was pounding so loud Saku was sure Yushi could hear it. When he looked up at his brother, the sight that met him caused a pit in his stomach and his cock to start leaking. His Yuu-nii is so beautiful. 

Dark, wild eyes that looked down at him in frustration and bewilderment, flushed cheeks, and messy hair all made him look even more perfect. If Saku didn't know any better, he'd say maybe he was even in love with Yushi. Just maybe. 

For a second, they just stared at each other, the only thing that could be heard was their heavy breaths. Yushi took it all in: the fact that he helped his brother with his first erection. The fact that said brother spent weeks afterwards trying to get Yushi to touch him again, and failing every time. The fact that his last attempt was surprising Yushi naked, in his bed, touching himself, and he finally succeeded. 

He lets out a low grunt as he realizes that he actually fell for it. But he doesn't want to resist anymore, why should he? No one will know, and he wants it just as much as Saku. He lets go of the younger's wrists, knowing they will stay up there, and brings a hand down to caress his side. 


“Baby… are you sure about this?” 

He looks deep into Sakuya's eyes and sees nothing but certainty and want. Saku nods and bites his lip. 

“I want to have sex with you, oniichan.” 


Yushi never thought he would hear those words from his brother, and it punches all the air out of him. There's no way this is really happening. His body is heating up, and his cock hangs heavy in his pants, desperate for release. 

He gives a quick peck to Saku's cheek before he steps away to strip, not caring where his clothes end up as he throws them behind him. 

At the sight of Yushi's naked body, Saku feels a pounding between his legs. He's never wanted anything this badly before. He rubs his thighs together, desperate for any friction, and it draws an evil smirk out of Yushi. 

Knowing that his baby brother is this desperate for him, having spent months trying to seduce him is incredibly flattering. And now Yushi thinks that there's no one else he would rather spend his first time with. 

He forces Saku's legs open again as he settles between them before leaning in to capture his lips. It's soft and sweet, it's like there's so much unsaid that can easily be conveyed through this kiss. When Saku draws back to catch his breath, Yushi follows, not satisfied quite yet. 

Saku giggles as he realizes that yes, maybe he is very obviously obsessed with Yushi, but it seems the older isn't much better, thankfully.  

Saku licks his lips before capturing Yushi's again, this time a little rougher. They're both growing more desperate, and when Yushi lets his hips grind down against Saku's, his jaw goes slack. 
Even with how much Saku has played with himself lately, nothing feels as good as when his brother is touching him. 

Yushi takes that opportunity to deepen the kiss, letting his tongue play with Saku's own. It feels so good, and Yushi can't get enough. If this is “wrong”, then he doesn't care about doing the right thing.

His hand, still stuck to Sakuya's side, now slides down his stomach and grabs hold of that small, stiff limb. Saku whines out loud as Yushi starts thumbing at his slit. He gives a soft peck, one, two, three times against those plush lips. A thought about how adorable his little brother truly is pops up in his head, making him smile into their kisses.  

The younger is whining desperately, managing to get a few words out that sound like ‘Please put it in’, which makes Yushi stop.


“Saku… do you know what you're asking?” 


His eyes are wide in surprise as he looks down at his brother's flushed face. Yushi himself barely knows how sex works, and he's definitely never stuck his penis in something other than his hand before. The thought makes him excited and nervous, he feels a chill down his spine. 

Sakuya sniffles as he feels the eagerness in him taking over.


“Yes, Yuu-nii, I know. I've been learning about it on the computer. I even put my fingers inside me to prepare. You can put it in, I want you to.” 


With those last words, Saku reaches down and grabs onto his brother's cock, giving it a squeeze that makes Yushi groan and jerk his hips. 
Completely contrary to his filthy hand movements, the growing smile on the younger's lips is innocent and genuine as he watches his brother, brows furrowed and eyes wet with tears threatening to fall.


“O-okay, baby. I'll do it.” 


Yushi lets out a breath and leans back on his knees as Saku loosens his grip. He spreads Sakuya's legs a little further and scoots closer, his crotch grazing against his brother's bottom. 
Saku's breath hitches and he feels his heart pound impossibly fast. Their eyes meet, and as they take a second to just hold each other's gaze, Yushi's heart melts. 

He loves his brother. The way he should love someone else, probably a girl. But instead, here they are, and he wouldn't want it any other way. 
With one last look at the unforgettable view below him, the cutest boy he's ever seen fully naked and ready just for him, he takes his cock in hand and gently pushes in. 

Saku grimaces at the sensation but crosses his legs behind Yushi, so he can't back out. The older huffs and shakes his head when his brother urges him to go further, but ultimately he obeys. 

Yushi bites down on his lip as he keeps pushing in, the younger is so tight and warm, it feels much better than Yushi expected. Impatiently wanting more, he thrusts forward, forcing a loud yelp out of his brother. 

Yushi's first instinct is to pull out and apologize, but when he looks at Saku's face, he sees nothing but a sense of contentment. His eyes are glazed over, and there's a tiny trail of saliva down his chin. 
He brings his hands up to grab at Yushi's neck, pulling him close for a slow, heartwarming kiss. 


“Yuu-nii- Hah, feels so good.” 


Hearing those affirming words is just what Yushi needs to realize that his baby brother isn't as weak as he looks. With that in mind, he pulls back before thrusting forward again, resulting in a low moan from Sakuya. His little cock is standing tall, a cute pink that just makes Yushi want to kiss it. Maybe next time.

As Yushi continues increasing his pace, Sakuya's eyes roll back, and he starts babbling incoherently. 


“Oniichan… hurts… love it so much…” 


It's not long before Saku starts whining again, a telltale sign that he's close to his climax, and when Yushi starts pulling at his nipples, the younger arches his back and squeezes his eyes shut. 

Sakuya is almost sure he peed himself when the clear liquid shoots out of him, but it feels so good that he doesn't even care. His whole body shudders as the last drops pour out over his stomach.

The sight in front of Yushi is unlike anything he's ever seen, and it's instantly too much for him. The tight heat around him clenches down and makes it impossible for him to move, in or out. 

He can't hold back, hips stuttering as he feels the release, Yushi's cock pumping his brother full with his cum. 


“Mmh, Yuu-nii, my belly feels weird. Am I gonna have a baby now?” 

Yushi laughs and leans in for another kiss. 

“No, silly. Two boys can't make a baby, don't worry.” 

Saku frowns slightly but happily meets Yushi's lips once again.

“But can we do this again? You and me?” 


Yushi pretends to think it over. Really, there is no debate about it in his mind. His brother was so determined to make it happen, and now Yushi might have a taste for it. 

Yushi smiles fondly at the younger, his heart aching with affection. 


“Yes, baby. It will be our little secret.”


He lies down on his side, facing his brother, and just takes him in. He's so beautiful, and Yushi is delighted that from now on he'll be able to kiss him whenever he wants. And so he does. He kisses Sakuya all over his face, on his cheeks, his nose, his forehead, and his perfect lips. 

It makes the younger scrunch his nose and giggle, a sound that always brings a warmth to Yushi's heart. As Saku wraps his arms tightly around Yushi and buries his head in his chest, he can only think of one thing. He's really happy his plan worked.

They lay there for a long time, in a warm embrace, hearts pounding in sync and soft sounds of ‘I love you’ being whispered back and forth until they fall asleep, still tangled together.
