They are all they have.

Their mother is dead, their brothers killed. Their father yet lives, but he sees them as shinobi first, assets second, heirs third, and sons somewhere far below. In a clan that prides itself on love, Tobirama has only Hashirama, and Hashirama has only him.

I'll take care of you, Hashirama told him as they stood beside a freshly dug grave, watching the coffin of their last brother disappear beneath incongruously clean soil. I swear it.

Hashirama hasn't broken his promise. But Tobirama knows how it weighs on Hashirama's shoulders, the burden of protection all elder brothers bear. He understands it well; he felt it for their siblings before war ripped them away. So Tobirama tries to ease that burden where he can, showing Hashirama how much he loves, and how he, too, will take care of his brother.

"Aah," Hashirama sighs against Tobirama's lips, an exhalation felt more than heard. Strong arms tighten around Tobirama's shoulders, urging him impossibly closer. "Mm…"

Tobirama presses his lips to his elder brother's, swallowing the hushed sounds as he works his fingers deep inside, stretching Hashirama, preparing him for more. They have to stay quiet: they can't risk someone overhearing. Such caution would be unnecessary if they could conceive an heir. Then, their shared blood would be welcomed, any offspring a pure Senju. But as it is, their union is a shameful indulgence, evidence of affection they are meant to have culled.

So Tobirama silences Hashirama's gasps, trying not to imagine what it would be like to make his elder brother moan his name.

Hashirama shifts his hips, pressing against Tobirama's fingers, silently asking for more. Tobirama obliges, drawing his slicked fingers out before pushing them back in, wrist flexing with each movement. In the beginning, this was as far as they went, bringing each other pleasure with hands alone. Now, Tobirama's cock aches with need, his desire to thrust into his brother's tight heat almost unbearable—but only almost.

Because this isn't about Tobirama's need: this is about Hashirama. This is about freeing his elder brother from the burdens of responsibility, if only for a while. This is about taking care of Hashirama in every way Tobirama can.

Gradually, Tobirama moves his lips down to Hashirama's jaw, tracing the strong line with gentle kisses. For a moment, he pauses, burying his nose just below Hashirama's earlobe, breathing in the pine-cedar-soil-life scent that clings to Hashirama's skin, listening to the steady thump-thump-thumping in his chest. Then Tobirama exchanges lips for tongue, licking his way down Hashirama's neck, savoring the salty tinge of sweat.

"Nn…" Hashirama arches his back, encouraging Tobirama's fingers and tongue. One hand slides from Tobirama's shoulders to his hair, tangling in silver strands, keeping him close. In return, Tobirama nips Hashirama's collarbone, drawing another muted sound from his brother's lips. Then he crooks his fingers, rubbing the place he knows brings the greatest pleasure, smirking as the smell of precum floods the air.

His brother may not be able to speak, but Tobirama can always tell what Hashirama most enjoys, the changes in scent unmissable. It's one of the many advantages to Tobirama's sensory abilities, though not one he applies elsewhere. For Tobirama, there is no one else who appeals to him as his elder brother does, no one he desires to pull close and kiss breathless.

After all, they are all they have.

Hashirama hooks a leg around Tobirama's, tugging him, impatiently demanding more than just fingers. Obediently, Tobirama lays between his brother's muscular thighs, slicking his cock with oil before lining it up. The tip brushes Hashirama's hole, teasing without entering. Then Tobirama meets his brother's eyes, eyebrows raised in a silent question: Are you ready?

Nodding, Hashirama loops his arms around the back of Tobirama's neck, fingers playing with the fine hair on his nape. Dark eyes gaze up at him, wide and trusting, unburdened by the weight of sorrow.

Leaning down, Tobirama kisses his brother tenderly, tongue parting soft lips to taste Hashirama completely. Then he moves his hips forward, cock pushing firmly against the tight ring of Hashirama's entrance, slowly but inexorably thrusting inside.

This time, it is Hashirama who swallows Tobirama's words, Anija whispered like a prayer. Tobirama can't silence himself in this moment; he never can. His brother feels perfect, hot and tight, enveloping him, holding him more intimately than any embrace. Shuddering, Tobirama forces himself to draw back ever so slightly, pushing further on the next thrust.

Anija, his lips mouth again, the word lost in their kiss. His hands find Hashirama's hips, holding tight as he thrusts, each movement slow and steady. Bit by bit, he sinks his cock into his elder brother, sheathing himself, joining their bodies as completely as possible.

Hashirama's lips move against Tobirama's, mouthing the words, I love you. Then Hashirama turns his head, kissing his way along Tobirama's cheek, breathing his next declaration against the red line marking it. I love you.

Tobirama buries himself to the root, feeling his balls press snugly against his brother's ass, eliciting a full-body shiver. Then he nestles his nose just below Hashirama's ear, breathing in his brother's scent, trying to keep his wits about him. Trying to remember that they must be quiet; trying to convince himself not to fuck Hashirama until neither of them can remember their names.

A thin trickle of sweat drips from Hashirama's temple. Tobirama turns to catch it with his tongue, licking it away. Hashirama sighs, quiet and blissful, and Tobirama licks again, drinking in the taste of his brother's skin. Then he rolls his hips forward, the motion smooth and powerful, thrusting as deep as he can.

"Yes," Hashirama whispers, the word barely more than a breath. "Tobi—"

Tobirama catches his brother's lips again, silencing his own name. Then he draws back ever so slightly, barely withdrawing before thrusting in again.

So often, it is Hashirama who sets the pace in their life. It is Hashirama who has impossible dreams, Hashirama who holds onto bright ideals. It is Hashirama who pushes Tobirama to do better—to be better—simply by striding ever forward, fearlessly leading the way.

But right now, it is Tobirama who sets the pace. Each thrust is smooth and steady, the roll of his hips like ocean waves, his cock staying buried deep inside. He kisses the words from his brother's lips, shushes the decorations of adoration and love. He doesn't need to hear the words: he can smell them on his brother's skin, taste them in their kisses, feel them squeezing hot and tight around his cock.

They are all they have. And they are enough.

When he smells his brother getting close, Tobirama slides a hand between their bodies, stroking Hashirama's cock. Hashirama arches into it, his moans vibrating against Tobirama's lips, his nails pressing into Tobirama's shoulders. Shivering, Tobirama picks up the pace, stroking in time with each powerful thrust. His teeth find his elder brother's lower lip, nipping it, whispering Anija into their shared air.

Then Hashirama comes with a muffled moan, his seed spilling hot and sticky between them, his body squeezing Tobirama's cock tighter and tighter. Gasping, Tobirama fucks his brother through it, his entire body tingling, his nose filled with the salty-sweet scent of cum. Then he buries his face against Hashirama's shoulder, hips jerking erratically, desperately chasing his own release.

Gently, Hashirama strokes a hand through Tobirama's hair, lips pressing against his ear. "I love you," he whispers, his voice deep and calm, filled with bliss.

Tobirama squeezes his eyes shut, reaching his peak with a shudder, spilling himself deep inside his brother. And there he remains, clinging to Hashirama, his mind blank, his senses tingling, his hips still twitching forward as though to push his cum deeper inside.

"I love you," he hears himself echo, a confession murmured against Hashirama's skin. It goes so much deeper than words, encompassing more than he could ever verbally express. He loves his brother; he needs his brother; he wants no one but his brother. As long as he has Hashirama, he is complete; as long as he has Hashirama, he is whole.

Hashirama strokes his hair, slowly bringing Tobirama back to himself. Reluctantly, Tobirama pulls his softening cock from Hashirama's body, soothing the sudden loss with a long, lingering kiss. Then he kneels between Hashirama's thighs, pressing a cloth between his brother's legs, cleaning away his own cum.

Hashirama starts to move, reaching as though to wipe away the seed splattering his abdomen. Immediately, Tobirama frowns, giving his head a sharp shake: Leave it. Then he ducks down, licking Hashirama's abdomen, savoring the taste of his brother's cum on his tongue.

Beneath him, Hashirama shivers, his hand returning to Tobirama's hair. A gentle tug is all the instruction Tobirama needs, immediately obeying the unspoken request. He lays atop his brother again, their bodies pressed flush, legs tangled together. Their lips find each other, kisses soft and sweet, saying everything they can't speak aloud.

Eventually, they roll onto their sides, arms and legs still curled around each other. Tobirama presses his forehead against Hashirama's, staring into his brother's dark eyes, tasting their shared air. Hashirama smiles, his thumb caressing the marking on Tobirama's cheek. Tobirama turns his head, kissing the pad of his brother's thumb, eliciting a soft chuckle from Hashirama's lips.

"Rest, Anija," Tobirama whispers, wanting nothing more than to watch his brother fall into a peaceful slumber. And Hashirama gives him that, closing his eyes with a smile on his lips, slowly slipping into sleep.
