Chapter Text
Tobirama hummed softly as he woke up on the last day of his heat, a heavy haze over his mind, and promptly bit tan shoulder again. The skin was already dark and purple with teeth marks.
Over the course of his heat, he'd drifted between being more or less coherent, registering Madara as a stable force beside him the whole time.
Even if that did mean using the other man as a chew toy, he was thankful for having a spotty memory instead of none at all. Currently, he was not thinking, wrapping himself around the nice-smelling man who was hissing something into his ear. He bit lower and lower, working down. His fangs were barely doing any damage at this point in his heat, dulled and weak.
How lovely, he thought, that he could do this without worry. Maybe he could stay like this forever, and never worry about anything else again. Just alpha and omega, wrapped up together. His mate was good, and Tobirama felt safe, and even the humid air around them and general dampness of both their bodies wasn't enough to put him off. Purring, he moved his head to gnash into strong bicep, finally stopped by a hand on his nape.
“Hnmff?” He hummed in question, blearily looking up from where he was busy leaving another bite mark, meeting his mate's eyes. “I know you tried to warn me but I didn't expect-” Madara started to murmur, only to wince when Tobirama removed his teeth. He gripped him harder, squeezing his nape until he whimpered and shut his mouth hard, not biting down again.
“I didn't expect you to be so…” The alpha waved vaguely with the hand not clutching Tobirama's neck, looking amused. “Untamed. It's cute.” Tobirama growled softly at that, even limp against his chest. Madara just chuckled in reply, toying with the hairs at the back of his neck.
“Let me go.” The omega grit out, red eyes full of vitriol at not being allowed to keep making Madara into a canvas of his usually repressed urges. “I need to- to-” He huffed, baring his teeth at the alpha. Madara bared his own back, growling a low, deep noise until the omega shrunk down.
Madara gently released his nape once he felt sure enough he wouldn't be bitten again, rubbing his scent glands down Tobirama's back. “What you need is to calm down. You'll be better tomorrow, or maybe in a few hours, if we play this right…” He licked his lips, eyeing the taller man over, an idea fluttering back into his mind.
“How about you lie back and let your alpha take care of you?” He rasped, grabbing Tobirama and rolling them over, smiling greedily. He got a click of the tongue in response but not denied, which made him smile. “I'll get the last of this pesky heat out of you.”

Tobirama had no idea that the Uchiha made something as simple as being mated so complex. Whereas as soon as Madara's teeth met his mating gland, he was as good as his to the Senju, the Uchiha clearly didn't agree. Hashirama sniffled as he explained that to Madara, who looked dumbfounded at the concept of it being so easy.
“I don't understand why I'm not allowed to nest with you until we finish all of this.” Tobirama said, eyeing the many, many forms in front of him, covering every clause and term that came with marrying into the Uchiha clan. It was very long and detailed, not that he minded the read. Apparently, there were different ones for if you'd already been mated, and he'd drawn that very short straw.
“I doubt my ability to sleep in your bed would be impeded by the possibility of-” He glanced at the paper in his hand, raising an eyebrow. “Me birthing your child and attempting to run off with them after they awaken the sharingan? Why would I, or anyone do that? After years of marriage?” Madara shrugged, looking quite charming in a pair of reading glasses that Tobirama had never seen on him before.
“If it were up to me, you would already be in my bed, I promise. And you would have a proper nest.” He smiled smugly, and Tobirama rolled his eyes. It was true, since their mating, he'd been packing his nest with more of Madara’s things, making it more full and plush. Then Izuna's things came into play, then Himiko and Hikaku’s.
Tobirama just grunted in response, focusing on signing the forms and ticking everything he had a question about. He wouldn't just let the Uchiha push him around, after all. Who's to say what might have been snuck into this form just for him? He wasn't just anyone marrying into their clan, after all, so he wouldn't put it past them…
–
It ended up taking months of debating with the Uchiha elders on little things- some Tobirama's complaints, some Madara's own- but they were finally approved to marry. The date for it was set for months out from then, but at least it was settled. Preparing for it was going to be hellish. The Senju elders weren't very happy about it either, no matter how open practice they were about mating and marrying. They didn't even have their own marriage rituals, so one of their own having an Uchiha marriage made some of them quite snippy.
Over those months, there were some eventful happenings, which Tobirama thought upon happily. One being Madara dragging Izuna in by the collar and slamming his head into the table in a bow. “He's very sorry. Say you're sorry.” He had snarled, Tobirama just staring.
“I already said I was sorry, let me go, aniki!” Izuna hissed back, looking back at Madara, who pushed him down harder. “You apologized to me. Apologize to Tobirama.”
Izuna huffed, looking up at Tobirama, dejected. “I'm sorry I told you the Uchiha traditions and Madara didn't follow them. I didn't think he'd be such a-” Before he could finish, Madara growled, releasing his brother, shouting about that not being a real apology.
When Izuna shouted back, both of them flaring angrily, Tobirama burst out laughing. These past few months he'd been experimenting with having his scent out more and more, and it turned out that having it free to be scented and swirl around made it easier not to feel sick whenever he smelt an alpha. “It's okay, I forgive him, I promise.”
He walked over and kissed Madara's cheek, who stopped snarling to blush. Then it was Izuna's turn to laugh.

The second thing Tobirama remembered was Mito coming for one of her visits. Shortly after Madara's rut, which- wow- he hadn't lied about also being a biter, Tobirama was terrified of what it would be like when their cycles did finally sync up, she came for an extended stay. Hashirama beamed with joy, showing her every new fixture around the village with pride.
Tobirama was sure he deserved it when she saw him and almost instantly smacked him with her fan, making him scowl. “He really was telling the truth! I can smell it on you!” She paused, then hugged him tight, seemingly putting together the rest of the details herself.
“I'm sorry, Mito…” He mumbled, her calming scent making him shudder. “I should've written to you, but I've been a bit.. Preoccupied.” The princess just snorted, breaking the hug. She stared into his soul, Tobirama feeling small under the short woman's gaze.
“You're going to tell me everything, ototo. I'm sure our fiances will be fine, I left them with a little something to do.” She smirked, and Tobirama felt sweat drip down his face, unsure what she meant. He nodded anyway. “Of course. What do you want to know?”
She smiled her usual fox-like smile, flicking her fan open as they walked. “Well, Hashirama's letter was a bit confusing. I believe he said something about you being courted by your own fated mate and rejecting him?” Her brows were up. Tobirama was sure one day someone was going to tease him and it would be his death. For now, he just sighed.
“It wasn't like that! He makes everything sound so dramatic.” He gruffed, preparing to lay out the full story. “I guess… Madara gave me a book as his first courting gift. But he was already interested before that. I was the one being a fool in this story, if you believe it.”
–
“Stop that, anija.” Tobirama gruffed, trying to get comfortable. Hashirama pouted in reply, pulling his wrists back from his brother's chin. “I'm sorry, I just.. You're going to be officially, fully Madara's now! I'll miss you so much. Our home will be so empty without you!”
The omega sighed, smiling at his brother. “Mito is moving in a month from now, don't be dramatic. I'm sure aneue will keep you very busy.” Hashirama whimpered again, and Tobirama wasn't sure if it was because he was still just moping or because he called Mito his sister.
“But I'll miss you, Tobi! What will I do without knowing you're down the hall, coming up with some twisted experiment?” He asked, frowning, hands sliding to try and scent him again.
Tobirama pushed the alpha's hands away, sighing fondly. “I'll visit every day. I won't stop being your brother just because I got married, you know, just like you haven't stopped being mine. Now stop trying to scent mark me, I'm supposed to smell pure when I go out there.”
With a crooked smile, and a final once over, he turned to finish getting ready. Hashirama had to join the rest of the crowd, after all. The wedding was a shockingly small affair, but he still felt oddly nervous.
Tobirama took a deep breath as he tucked his hair behind his ears, trying to keep it out of his face, the wild curls trying to defy him still. He kept his steps firm as he met Madara's eyes, ignoring the crowd as the tapped wrists, shuddering as he met his sharingan, forcing himself not to look away.
He stiffened as Madara's wrist left his, just as they'd practiced, and moved to his mating gland, marking him with his scent. They stayed silent until they walked out, sitting on the bench behind the small hall. Madara's smile went lazy and warm. “You did well.” He said, rubbing his eyes, aching slightly from both using them and the high ponytail he was wearing.
Tobirama moved to soothe his temple, rubbing it with a bit of healing jutsu, Madara chuffing. “You need not heal me, omega, I've felt worse.” He said, even as he smiled. Tobirama scoffed, moving to kneel closer, straddling one thigh as best as he could. “So you'd rather I leave you in pain? On our wedding night? Who do you think I am?”
The bench behind the ceremonial hall was hard and firm, and they surely made a ridiculous sight. Both in the fanciest kimonos, Madara's black and Tobirama's Uchiha blue, cuddled together on a bench, newlywed and purring like idiots.
“Just shut up, alpha. I've got you.” Tobirama muttered, a fond look crossing his face as he rested against his husband, warm and loved. Madara obeyed, letting himself be healed, wrapping his arms around his waist. “I love you.” He said, face pressed against the omega's chest.
“I love you too.”

Tobirama grinned as he opened the door, walking slowly, running his hand over the spines of every book he could touch. “Wow.” He said, mouth agape. He couldn't help it. “It's amazing.”
Hikaku was beside him, here to ‘guard’ him, but truly just taking the easy task of the day away from Izuna, who was busy looking over files on the newly formed Anbu. “I know, isn't it?” He said, leaning against a shelf with a smile.
Tobirama nodded, grabbing a scroll in a careful fist, cooing as he examined the old text. “How far back do these go?” He asked, eyes shining. The beta shrugged, looking around the veritable maze of scroll-lined shelves that made up the lovely library that he was allowed inside of.
“I'm not entirely sure. But, you do have the rest of your life to find out.” Tobirama smiled at that, possibly even brighter than he had on his wedding day.
