Too Hatake (1/?) - Tobirama/Madara
The smell catches him completely unaware; he’s running back to the compound after an extended diplomatic mission with the Nara, and he’s mentally exhausted, but it curls into his brain and he finds himself diverting from the most direct route home in order to chase it down. Given the smell, it’s likely to be a wounded stag, whose meat will be welcomed by the clan, and he’s been craving venison fiercely; too much Hatake blood, and too long being taunted by the Nara deer.
(He’d didn’t feel his Hatake blood often; he didn’t have their chakra or their lightning affinity, but sometimes, when he was tired, instincts that weren’t quite human would prod at him. Given a choice he wouldn’t have spent a month with the Nara, but sending Hashirama or Touka to negotiate with them would have been a bad idea.)
He chases the scent down, suddenly hungry, and something clicks in the back of his head. It’s a semi-ominous sensation, but he’s locked onto the most delicious scent and he’s too tired to resist the urge to chase, even though his chakra is flaring in the strangest way. Normally he’s water natured, but his energy feels almost electric in the way it’s shifting under his skin.
He barely registers the shift from two feet to four paws, or the way the white fur - his birth gift from the Hatake - rippling and covering his skin. (That he doesn’t notice the shift will alarm him, later, but only make his Hatake cousins laugh, hysterically. He wonders if they would have stolen him away if he’d shifted when he was younger.) The scent in his nose is even stronger than it had been earlier, and he pushes more of his chakra into his muscles, lending him a burst of speed that has him leaping between tree branches as he closes in on the delicious smell.
He pounces, teeth bared, and the shinobi goes down under him, red armour no match for chakra enhanced claws, and the blood tastes so good when it splashes onto his muzzle. His chakra bursts from his skin, bright and white and scorchingly hot even against his skin, and releasing that much undirected-chakra should have him panting, winded, reaching for the hiraishin to get some distance from whoever it is he’s fighting. But it doesn’t. It leaves him invigorated, hungry in a different way, the man beneath him naked, human skin, bloody, pressed against his pure white pelt, and he’s confused as to whether he’s supposed to rend and tear, or drive himself inside it with a harsh thrust. He settles for both, holding the man in place with chakra and teeth as he shifts his hips, the tip of his cock sliding against sweat-slick skin until it lodges and he snaps his hips forward.
There’s a scream, but he rides the way the body beneath him bucks, teeth still lodged in his prey’s shoulder and the feel of hot tight flesh convulsing around his cock. He ruts frantically into the sheath around his cock, laps at the blood oozing from his partner’s shoulder and then he’s stuck, a knot forming at the base of his cock, locking him in place, and he pants in pleasured exhaustion as he shifts back from wolf to human, sprawled over his new mate’s back. (Mate is not his choice of word, but it feels right.) He rests his head against the bloodied shoulder, tries to figure out what happened, why he’s got a mouthful of blood and his cock locked - with a knot he’s never had before - inside another man.
“Fuck.” The voice sounds familiar, and the hips beneath him shift, dragging a snarl from his throat that surprises both him and the man he’s tied to. “Goddamn Hatakes. There aren’t supposed to be any of you on Uchiha lands even if you aren’t Senjū allies anymore -”
“Madara?!” His voice is higher-pitched than it’s been since he was a teen, and the hips beneath him shift again, causing his knot to tug at the vulnerable ring of flesh it’s wedged beyond. His chakra is still white, still crackling like Lightning, prickly to his touch, and he assumes it’s the only reason he hasn’t been recognised and flambéd. “I was hunting food -”
“You sound familiar -” he’s tempted to snarl an ‘of course I sound familiar, you idiot, I try and kill Izuna on a regular basis’ but decides that discretion is the better part of valour sometimes. Fire-natured chakra - with far more yin mixed into it that there ever was on the battlefield - washes over him as if Madara’s searching for something and maybe there’s an actual brain under all of that soft fluff masquerading as his hair?
Whatever the Uchiha’s looking for, he finds it, and for that matter, why didn’t he rip the Uchiha’s spine out when he had a chance? His bite had gotten perilously close to severing something important, yet he hadn’t taken that final step; he’d chosen a different one, and he’s confused. Madara rolls beneath him and makes a broken pleasured sound as the movement shifts them both and his cock is making absolutely no complaints about things.
But humans aren’t supposed to do and take what he just did to the older man, and there was a reason he hadn’t killed him, and it wasn’t so he could die of acute peritonitis. Which meant that he should probably figure out if he had enough control to use his yin chakra through the haze of Lightning that was coating everything including his ability to sense anything more than six feet away. It slips and slides from his grasp in a way that’s infuriating and has him growling at the back of his throat, Madara’s chakra flaring in response, an instinctive submission that had him even more confused than he had been.
“You need to heal yourself. I can’t make my chakra behave -”
“- Senjū.” The word is spat, and he’s really not surprised. The way that Madara’s chakra reacts? Now that’s a surprise, and he buries his head in soft black hair and rides the way that Madara writhes beneath him, presumably trying to get his hands on him to strangle him? It does feel amazing, though, his knot keeping him firmly anchored inside the Uchiha and he was going to have to interrogate his cousins. Later. Much later. Maybe when he’d cum again. “I didn’t realise you were this Hatake. Did you realise you were?”
He turns over the pieces in his head, puts them together, feels yin chakra in the flesh his cock is still firmly embedded in, healing the tears he’d inflicted, the way that Madara seems almost calm again despite the way he’d bucked and squirmed under him. “My mother was Hatake.” There’s a snort from his mate.
“Hashirama’s half Hatake? And Butsuma caught a Hatake wolf - you’ve got to be fucking kidding me.”
“No he’s fully Senjū. Kaa-chan was Butsuma’s second wife and a treaty-bride, and why the fuck am I telling you any of this?”
“You’re Hatake.” He makes another of those low growls that has Madara’s chakra flaring in submission, confused as to why the Uchiha thought that was an answer. “I assume she couldn’t shift. The treaty-bride that came to the Uchiha couldn’t. Did she not teach you the lore anyway?” He groans and buries his head in Madara’s dark hair. “I’ll take that as a ‘partially’. And be grateful I know and have some Hatake blood. Or you’d already be burning, Senjū.”
“Niisan’s going to be intolerable.”
It takes Madara moment to realise what he means. “Fuck, he is, isn’t he. Almost as bad as my otouto will be.” The body under him goes limp, and he can almost hear the wheels spinning in his head. And then there’s a flare of chakra - the summoning jutsu - and a small nin-neko appears. Fortunately, his instincts don’t try to demand that he chase it; he suspects that would piss Madara off far more than being hunted like a particularly tasty stag for some reason. “Tell Izuna that I’ve got to see great-grandmother’s clan. Something from one of the old treaties came up. He tries to follow and he goes in the koi pond.”
“Your otouto will likely end up in the koi pond anyway.” The nin-neko flicks her tail. “He annoys the kunoichi far too readily for anyone’s sanity, and like any sensible queen would, they’re training the silly kitten to behave.” Madara snorts. “You will summon me somewhere safe when you get to the wolves. The queens will wish to know you’re content with your tom.” The nin-neko vanishes before either of them can respond to her and Madara sighs.
“You may have to refill the pond for me when we return.”
“Why -”
“Great-grandmother hunted and kept her husband, and two of their children went back to the Hatake because they shifted, and that was part of the negotiations. I know what it means that you caught me, but I won’t leave my clan -”
“- I don’t understand!” His Chakra flares, coaxing another answering flare from Madara’s.
“The great Senjū genius not knowing something. This is hilarious.” He sets his teeth back to the wound he seems to have gnawed into the Uchiha’s shoulder; he’s not sure why it’s so pleasing to him to taste the man’s blood, but given the way that Madara goes limp again, he’ll have to keep doing it. “Shit. Stop doing that. I can’t think.”
He suspects that’s the point as far as his instincts are concerned.
His cock finally softens, the knot at the base of it that had kept him so firmly tied to the Uchiha releasing, and he rolls away from Madara, somehow trusting that he wouldn’t get a kunai to his throat now that he was no longer pinning him. “Explain.”
“No. We’re going to the Hatake, even if I have to tie you up in chakra wire and carry you there.” A shiver goes up his spine, at the idea, and Madara laughs. “Perhaps that shouldn’t be a threat, but a promise, Tobi-kun. It would certainly save my arse from being mounted again until I can study the appropriate jutsu.” He snaps his jaws, body twisting under his chakra’s influence and lunges for the Uchiha again, sending them both tumbling in the dirt and leaving him frustrated when his mate - his bitch - doesn’t present properly. “Hatake. Jutsu. Treaty.” Madara rolls beneath him, fighting what had to be instincts almost as strong as his, and his eyes whirl into the mangekyo and a genjutsu drags him down into oblivion.
