"It's been so nice to be able to have dinner at home for a change! I've loved seeing all of you."
"It's been so good to have you home, Naruto. I know the kids have loved it."
As always his mom and Himawari eat up his dad's bullshit like candy. Kawaki doesn't say anything as he sits beside him, but he does give the great Hokage a small smile that turns Boruto's stomach. Because they always seem to be giving each other those looks, like they have some kind of secret between them that no one else knows.
But what really pisses him off is that suddenly his dad can find a reason to make it home and act like he's a part of their family. Ever since they took Kawaki in he's home more often and acts like it's perfectly normal, at least on the outside. It's so obvious that his dad treats handling Boruto like it's some task handed to him rather than a father spending time and training his son.
Boruto has long since accepted it for what it is, he's the son of the Seventh Hokage so he knows… he's always known exactly where he stands on his father's list of important things. He's fairly certain he and Himawari rank somewhere under their mom, who is under Uchiha Sasuke and the rest of the village, because everything and everyone seem to be more important than them-but especially Boruto.
So it makes absolutely no sense that Kawaki seems to get so much attention.
And it only got worse once Kawaki officially moved in with them. Because now Boruto has to share a room with him and listen to the casual way his dad-the man who rarely acknowledges anything Boruto does-how his dad has no issues telling Kawaki how great he's doing in training or giving advice or taking time to teach him a technique he's struggling with.
Everyone says it's because Kawaki had it rough just like his dad did when he was a kid, and at first Boruto understood it, he really did. But it's been months of this, and at some point he was sure Kawaki would get treated like the rest of them, second class citizens in the shadow of everything and everyone else around them.
But it hasn't happened yet.
The exact opposite has happened.
His dad, Uzumaki Naruto, the Seventh Hokage of the Leaf Village, changed because of him. Birthdays didn't matter, family dinners didn't matter, having a family at all didn't matter… until Kawaki came along. And maybe Boruto should be thankful in a way, because now he sees his dad more, but he still can't help but feel like a second class citizen in his own home.
Dinner goes on with everyone talking about their day and pointless other stuff that Boruto doesn't really listen to, especially when Himawari gets to talking about school and her friends. As soon as he's able, he excuses himself from the table and disappears into his room for the rest of the night, only coming out to take a bath and grab a snack from the kitchen when no one is looking.
He's coming back in with the apple he snagged from the kitchen right as Kawaki comes out the bath, a towel wrapped around his waist and a deep crimson flush running from his face to his chest like the water was too hot. He avoids looking at Boruto as he looks for clothes to wear to bed.
There's the awkward silence between them like always, neither of them really knowing what to say. Well... for Boruto it's different, he knows what he wants to say, he just knows he can't, his dad would get pissed if he was anything but pleasant to his precious new son.
So the silence settles, Kawaki pulls on a pair of shorts and a shirt and climbs in bed. And Boruto finishes his apple, tossing the core in the little trash can by his desk, and climbs into his own bed before shutting the lights off.
He falls asleep without a second thought.
It's the sound of hushed voices and the subtle creak of Kawaki's bed springs that pulls Boruto from sleep… that and he really needs to pee. He's about to get out of bed and do just that when he catches a familiar voice coming from behind him
"Always so good for me, Kawaki. I can feel you shaking."
Dad?
What the hell was his dad doing in here? And why was he talking to Kawaki in the middle of the night?
"B-Boruto will wake up if you keep talking like that." Kawaki says, but it sounds weird, like he's struggling to catch his breath. His voice is kind of muffled too, so Boruto has to concentrate really hard to hear him even in the quiet room.
"You always say that," there's a rustling sound and Kawaki sucks in a breath as his dad keeps talking. "But not once has he ever woken up. Even on that night you bit your pillow so hard you ripped it."
"N-Naruto…" Kawaki whines, and Boruto feels his entire body freeze in place.
His dad is doing… things to Kawaki. It's why he sounds like that, why his dad is in here so late at night… and why Kawaki is so special to him.
"Shh, I've got you. And you're eager tonight, huh? You didn't even wear underwear to bed." The bed creaks again, one or both of them moving around on it, and then Boruto hears; "Were you hoping I came in tonight, Kawaki? Are you that needy?"
It's... it's disgusting and this is insane. He should get out of bed and say something, let his dad know he's been caught and stop this-but Boruto can't move. He can't move because there's a tent in the front of his shorts from listening to his dad talk to Kawaki like that and from the sounds Kawaki keeps making every time Boruto hears them shift on the bed.
Boruto hates this, hates them, because he wants to know exactly what they're doing and why Kawaki's breathing is getting more and more erratic as the seconds tick by.
"Just like that-perfect, always so ready to make me proud-just like that, good boy. Open up for me, baby, relax. You always take it so well."
The bed shifts again, harder, and the sound Kawaki lets out has Boruto shoving his hand into his underwear. Why could his dad never praise him like that? Was… was this all it took for Kawaki to make him proud?
"Fuck, you're so tight. That's it, my sweet thing, take it all."
Boruto has to squeeze himself to hold off the rush of pleasure crawling up his spine. He's never heard his dad sound like that, whispering so much praise and affection into Kawaki's ear as he...as he...
"Touch me, touch me, please? Naruto... Daddy, it's so much."
Boruto can't take this anymore.
He makes a show of turning over, sure they still think he's sleeping, and pulls his blanket over his head as he lets out a fake snore just to sell it. He needs to see what's happening, needs to know why Kawaki is so special while Boruto is next to nothing in his dad's eyes. Daddy-anger burns white hot in the pit of Boruto's stomach at hearing Kawaki call his dad that, like he's actually part of their family when they are doing that right next to him.
Maybe Boruto should be careful what he wishes for…
He pushes his blanket aside, just enough to make a small opening so he can peek through without getting caught, and nearly cums in his shorts at what he sees.
They aren't even trying to be discreet or hide in case someone catches them.
Kawaki is on his side, his shirt pushed up his chest and his shorts lying on the floor, and Boruto's dad is behind him. He's holding Kawaki's leg up just under the knee, his other hand going between Kawaki's legs to 'touch him' exactly how he'd asked. The most shocking part of this is the way Kawaki's body rocks forward steadily, the noises he was making before Boruto now understands were moans, because Kawaki has his face pressed into his dad's neck as he arches into the steady rock of his dad's hips.
Their… their having sex.
Their having sex right in front of me.
And Kawaki is enjoying it. He likes it going by the way he clings to his dad's shirt, pushing himself into the hand wrapped around his dick, and moaning his name like he can't get enough. Kawaki is calling him Daddy, begging him not to stop as Boruto watches Kawaki's stomach bulge every time his dad snaps his hips forward.
My dad is fucking Kawaki.
And Kawaki's face, usually so sharp, so intense, is so uncharacteristically soft as he pants out needy little breaths until his dad finally leans down to seal their lips together. Boruto doesn't think his dad kisses his mom like that, but he pulls Kawaki closer and Boruto can see the way he licks into Kawaki's mouth as he yanks him back using Kawaki's leg, the one he's been holding this entire time.
"Am I good, Daddy? Do I feel good?" Boruto never knew Kawaki could sound like this, so soft and desperate for attention when he literally spends all his time pushing everyone away… everyone except his dad of course.
"Oh, baby, you're absolutely perfect." comes the groaned out reply. "My strong boy, couldn't take my eyes off you today."
Boruto doesn't have to wonder if it's true or not, he was there. On the training grounds today Kawaki was the only thing his dad was paying attention to, and now he knows why.
"Your jutsu has gotten so much better, and you've gotten so fast," It's like just talking about how great Kawaki is works his dad up, because Kawaki lets out a particularly loud moan that he has to cover up with his hand when the pace suddenly increases and he can't keep up. "I could hardly keep up with your movements as I watched. Wanted to take you into the forest and show you just how proud I was."
It's not fair.
It's not fair!
Boruto's hand moves in time with the slick, obscene slapping sounds of Kawaki getting fucked by his dad. He feels so gross doing this, the very thought of it makes his stomach roll, but if he closes his eyes Boruto can almost pretend all this praise is for him. And that makes him feel even more disgusting.
He's been watching and listening for so long it takes nothing at all for him to make a mess all over his hand and in his underwear. Boruto tugs at his own cock with rough, jerky pulls as the disgust rolls through him in waves, until finally it comes to a head and he's left shaking as a sticky mess forms between his legs.
The sounds of them going at it, his dad still uttering mindless praise as Kawaki begins to lose control of his voice, continue without pause so Boruto is sure they didn't notice the little choked off sound that escaped as he spilled over his fingers.
When he peeks through the little hole in his blanket again Kawaki is crying into his pillow as he makes his own mess all over his dad's hand and his thighs. He shakes through it and a wet sounding sob, loud enough to actually wake Boruto if he weren't already up, echoes through the room and it's like neither of them even care. If anything it makes the hand currently working over Kawaki's dick move a little faster, his dad muttering something incoherent that Boruto can't quite make out.
"Inside, cum inside, Daddy." Kawaki whines as his body goes limp, and a few moments later his dad does exactly that, coming with a deep grunt and Kawaki's name on his lips as he buries himself inside one final time.
It's weird now that it's suddenly all over, like seeing them finish has made Boruto hyper aware of how cold and sticky his fingers and underwear are and how gross it was for him to watch and get off on this in the first place. At least, that's how it's supposed to feel. But all he feels now is jealousy as he watches his dad run his clean fingers through the sweaty strands of Kawaki's hair, kissing at his cheeks and lips and shoulders as he tells him how well he did, how Kawaki is so precious to him and perfect in every way.
Boruto wants that.
He wants it and he'll never have it.
And he hates the two of them all the more for it.
But he continues watching anyway. He watches the strange tenderness with which his dad handles Kawaki, how he cleans them both up as best he can (suddenly they know how to be quiet) all before finally kissing one last time, Kawaki so reluctant to let 'his Daddy' go.
"I hate when you leave. Wish you could stay with me."
"I know, baby. I wish I didn't have to."
Boruto hates how genuine that sounds.
They kiss again, this time it's his dad who can't seem to let go, and Boruto's watching him fix his clothes and head for the door. Kawaki looks like a kicked puppy as he watches him leave and something inside Boruto loves that more than anything. He listens to the footsteps walk past his bed before suddenly stopping at the door, no doubt wanting to puke more praise at his perfect new son, but Boruto's blood runs cold when he hears;
"And Boruto? I look forward to seeing you tomorrow in training."
