"Come on, Uncle 'Zuzu! You're so slow!"

"You'll be eating those words once I catch you, ya little twerp!"

"I'd like to see you try!"

Tobirama watched on with a smile as Izumi constantly slipped out of Izuna's grasp. It was times like this when she would play tag with Izuna that her lineage really showed. Being the daughter of two clan heads belonging to the two greatest ninja clans known to shinobi history would give her many advantages over other children. Like her mother, she was quick-witted and deceptively agile while she observed her opponent's weaknesses and plotted accordingly. Like her father, she knew when to take things seriously and when she could let loose and have fun.

Izuna dove at her, snatching her legs by surprise. Izumi let out a startled squeak before she landed on the floor with a thump. Izuna proceeded to flutter his fingers down her sides. She burst out laughing as her uncle continued to tickle her.

"Uncle 'Zuzu, stop!" she cried, trying to escape her tickle torturer. "I can't breathe!"

"I told you I'd make you eat those words!" Izuna declared triumphantly.

"I give! I give! I'm sorry!"

Izuna began laughing himself, pulling his niece into a hug. She giggled, wrapping her little arms around his neck. She looked Izuna in the eye, her wood-colored irises sparkling with innocence and wonder.

"Hey, Uncle 'Zuzu? Why don't I have any cousins?"

Izuna gaped. "Huh!?"

"Well, Daddy and Mama have me, right? Can't you and Uncle Tobi get a kid too? I want a cousin to play with. That way, all of us can have even more fun together! Wouldn't that be great?"

"Izumi-chan…" Izuna sighed. "That isn't possible for me or for Uncle Tobi. We don't have the right equipment to get a baby."

"What kind of equipment do you need?"

"Very special equipment; so special that it's impossible for normal men like us to obtain it. Both your mother and father are great men, so they were blessed with that equipment. With it, they were able to get you."

"Really? Can't you ask Mama or Daddy if you can borrow it?"

"No. We can't. It's forbidden for others to use it."

"Oh…"

"But…" Izuna said, his grip on Izumi increasing slightly. "If there was a way for me and Uncle Tobi to get a baby, I'd do it in a heartbeat."

"What do you mean?" Tobirama questioned curiously.

"Well…Look at Izumi for example," Izuna began, holding her up for Tobirama to see. "She's a wonderful kid and I love every moment I spend with her. I want to be able to share this kind of bond with a kid of our own."

"You know, there's always adoption."

Izuna shook his head. "I'm not against adoption, but I really want to have a child born from us; just like Izumi was from our brothers. I know it's an impossible wish, but…I want to raise a family together with you more than anything…"

"Izuna…"

"I know my ideas are oftentimes ridiculous and downright crazy, but I mean it this time. If it was possible, I would definitely have a child with you."

"Don't worry, Uncle 'Zuzu!" Izumi exclaimed. "It's okay! I'll ask Mama if I can borrow his equipment to make a baby for you two! Girls are allowed to use it, right?"

"That's very kind of you, Izumi-chan," Tobirama said, ruffling her hair up. "But I think it'd be better if you didn't speak about it. It's a very sensitive topic to bring up to your mother."

"Well, I can still ask him and Daddy if they'll help you, can't I?"

"No."

"But Uncle Tobi—"

There was a loud crash that came from a different room in the house. Izuna picked up Izumi, rushing toward the area where he heard the sound with Tobirama following after him. They entered the main living room, finding a prone Hashirama laying on the floor with a seething Madara hovering over him.

"I specifically told you I didn't want to go through it again!" Madara furiously roared, his hands placed in the Tiger seal to perform a Fire Style jutsu. "You never listen to me, you idiot!"

"I'm sorry, Madara!" Hashirama wailed, covering his head to shield himself from his husband's wrath.

"Mama, what happened?" Izumi cautiously asked, hiding a bit into Izuna's chest.

Madara stopped his rampage long enough to notice his daughter in the room. He sighed deeply, walking over to Izuna and taking Izumi out of his arms. He held her close, looking into her eyes with a sheepish expression on his face.

"Izumi-chan, you know how I've been sick recently?"

She nodded. "Yeah. I was worried about that. Is something wrong with you?"

"Well…yes and no."

"You're not dying, are you!? Please don't die, Mama! I love you too much! You can't die!"

"I'm not dying, Izumi. I'm just…"

Izumi cocked her head to the side. "Just what?"

"You're going to be a big sibling pretty soon."

It took a whole three seconds for Izumi to comprehend her mother's statement. When it processed, she let out a loud cheer before she began hugging Madara.

"I'm getting a baby brother or sister!?" she squealed happily.

"Yes. Yes, you are," Madara answered, smiling at her excited reaction. "But he or she won't come for several months, so you have to be patient."

"I'll be patient, Mama! So where's the baby now?"

"What?"

"Uncle 'Zuzu told me that you and Daddy have special equipment that you use to grow the baby. Where is it?"

Madara sent a sharp glare at Izuna, who had partially hidden himself behind Tobirama. He turned back to Izumi, placing her down on the floor. She blinked her big eyes as she watched Madara take her hands. He led them to his midsection and placed them against it. She explored a bit, pressing lightly on his abdomen. She then beamed.

"Your tummy's roundish!" she giggled. "The baby is inside you?"

"Yes."

"You didn't eat it…did you, Mama?"

Madara laughed. "No, I didn't eat it. Baby needs help from me in order to grow, so it'll be living in me for a while. Baby will come out eventually, but you have to wait before that happens."

"Oooooooh! That's okay then!" Izumi exclaimed before she snuggled up against his belly, wrapping her arms around his waist. "Hey, baby! This is your big sister! I can't wait to meet you, so grow up fast, okay?"

Izuna laughed to himself, watching Izumi poke at his elder brother's stomach. He then looked to Tobirama, wondering if he found the scene to be hilariously cute too. He found his husband with a stern look on his face, his eyes distant and his hand placed near his chin. He seemed to be thinking deeply about something.

"Tobirama?" Izuna asked. "What is it?"

"It's nothing," he replied. "I've been thinking about what you said. I think I know how to make it a reality."

Izuna raised an eyebrow at the calculating smile that spread across Tobirama's face. "Huh?"

"You'll see…in time."

"It's finally done."

"What is, Uncle Tobi?"

"That's for me to know and for you to find out."

"Come on, Uncle Tobi! Don't be sneaky! I know that look. You came up with a new jutsu, didn't you?"

Tobirama sighed at the child who had decided to hang on his back like a monkey. He couldn't tell her exactly what he had accomplished. For the past two years, he had been working on a way to make Izuna's dream a reality. As much as Hashirama had joked about him making a Fertility Jutsu, Tobirama had actually decided to create it.

Much had happened in the two years that had passed while Tobirama was busy working on the jutsu. The most notable thing was the arrival of his nephews. Hashirama was pleasantly surprised when Madara gave birth to twin boys. Madara, though he was happy with his new sons, swore he'd make Hashirama suffer after the torture he went through: double the morning sickness, double the cravings, double the mood swings, and double the weight gain. Madara still bemoaned about the visible stretch marks he had acquired during that little adventure. Tobirama silently thanked the gods he would never have to go through that torment.

He had to thank Madara for allowing him to "study" his bodily changes during his pregnancy with the twins. When asked why, Tobirama had revealed his intentions to give Izuna the family he so desperately wanted. Madara had teased him about becoming soft, but the Uchiha was more than accepting of Tobirama's prodding if it would potentially make Izuna happy. Using the data he had gathered from observing Madara, Tobirama had tried to work it into a jutsu where it would give the target a similar functioning womb. In short, it was supposed to temporarily make the target a hermaphrodite like Madara and Hashirama. He knew there could be kinks he had to work out, but it wasn't like he could test it on just anyone.

He felt tugging on his pant legs, bringing him out of his thoughts. He looked down, finding one the twins trying to get his attention. He bent over, picking the child up. Large black eyes and a mop of half-black, half-white hair stared back at him.

"Akio, I can't play with you right now," he said. "Uncle Tobi is busy."

Akio frowned, his lower lip trembling. Tobirama inwardly groaned. Compared with his elder twin, Akio was a crybaby. Tobirama supposed he got it from his late uncle, Itama. But despite that, he almost always had a smile on his face and seemed to have a laidback personality much like his father. His brother, Ryo, looked like a mini Madara with brown hair. He seemed to have a short fuse and got annoyed fairly easily. He also had his mother's issue with people standing behind him. Despite that, he was always at his happiest when around Akio.

He felt Izumi get off his back, skipping up to Akio. She took hold of her little brother, beaming at him.

"Come on, Akio!" she said. "You can play with nee-chan! Won't that be fun?"

"Ah!" Akio cheered, smiling with glee.

He watched as Izumi carried Akio away. Despite the amount of trouble those kids managed to get into, he always had a good time watching over them. They weren't spoiled little brats that craved constant attention. Izumi was well-mannered for her age and the twins seemed to be picking up that feature from her. All three of Madara's kids were a joy to be around.

"And maybe we can raise a child like them too," he mused.

Tobirama felt something odd swell in his chest at the thought. Despite his cold outlook, Tobirama treasured children and he always secretly wanted to have some of his own one day. Now, with his Fertility Jutsu in existence, it seemed both he and Izuna would be able to gain the child they wished for.

He heard the front door open. He turned his head around, finding Izuna standing there. The Uchiha walked up to him, a huge smile on his face. He had his hands hidden behind his back. Tobirama smirked at his husband and his cheesy attempt at concealing something. Izuna whipped out his hands, revealing what he was hiding.

"Happy anniversary," he said cheerily, holding a new happuri with Konoha's symbol emblazoned on it. "I made it myself…mostly. I had some help…"

Tobirama took the metal headgear, placing it upon his head. It fit snugly on him, which he was grateful for. He smiled at Izuna as he took the happuri off.

"Thank you," Tobirama said, pulling Izuna into a warm embrace.

"Don't mention it," Izuna replied. "I did my part. Now it's your turn."

"I can't give it to you right now."

"Why not?"

"It's a secret."

"Aw, come on! Don't leave me in the dark now! Tell me what it is!"

Tobirama smirked at Izuna as he pulled away from him. He took hold of Izuna's hand and lead him out of the room. Izuna had hundreds of questions fly through his mind as Tobirama began pulling him towards wherever their destination was. They passed by numerous households and streets of Konoha. Some passerby greeted the couple on their way. Izuna soon recognized where Tobirama was taking him. The Senju was heading towards Hokage Mountain. A slew of memories came rushing back to him as he stared at the golden stone of the cliff face. Tobirama released his grip on Izuna's wrist when they finally reached the top of the mountain. Izuna looked around briefly before he focused his attention back to his husband. Tobirama was standing near the edge of the cliff, looking down over the village.

"You remember when this area used to be nothing but trees?" Tobirama asked aloud as Izuna walked up to stand next to him.

"Yeah. I also remember back when this cliff didn't have your brother's ugly mug carved into it."

"And you still remember what this place was back then?"

Izuna nodded. "Of course I do. This was the place we first met. It's also the place where I proposed to you and you subsequently proceeded to whale on me before accepting it."

Tobirama frowned. "You announced it loud enough so that the whole village could hear you. It was disturbing and downright embarrassing. How did you expect me to not have a negative reaction?"

"Hey, people do crazy things when they're in love," Izuna answered with a shrug.

"I know," Tobirama said. "I believe it now more than ever since I've done the same thing."

"Huh?"

"Izuna," Tobirama began. "You and I both know it's impossible to raise a family of our own."

"Oh, no! You did not! You didn't…?"

"I did. I—"

"You adopted a kid without my consent!?" Izuna interrupted in shock.

Tobirama slammed his palm against his forehead. "No! I made a jutsu so we can have kids ourselves, you fool!"

Izuna froze at the words, his eyes widening in surprise. "What?"

"You told me two years ago that you wanted to have kids of our own, but you lamented the fact that it would never happen since we don't have the same 'gifts' as our brothers. I've been working on a way for it to be possible for one of us to…carry a child."

"So all those times when you told the kids you were too busy…you were working on a Fertility Jutsu? Just so we could have a child born from us?"

Tobirama awkwardly nodded. He felt a body crash into his chest, arms tightly wrapped around him in a hug. Izuna was trembling slightly, but it was not out of sorrow. Izuna started laughing, tears falling down his face.

"You're such an idiot!" he exclaimed. "I'm…I don't know what to say."

"You can say 'thank you'. It's common courtesy to do so," Tobirama sarcastically replied.

"I guess this news is your anniversary gift to me?"

"Yes. Yes it is."

"So…which of us is supposed to be the mother?"

"Well, I intended it to be you when I started working on the jutsu. Unless you have qualms about it…"

"Oh, believe me; I don't," Izuna answered. "I'm so happy right now. Even though I know the symptoms are going to be hell, I'm more than willing to deal with them. Tobirama…thank you so much for doing this."

"You're welcome, Izuna."

Not long after Izuna heard the news of Tobirama's Fertility Jutsu, the two shared a very sensual night together. Tobirama told him that he had activated the jutsu before they went at it like they normally did when they felt like it: taking turns and switching positions for the other. After that night, Izuna was impatiently waiting for the symptoms to start. He occasionally lifted up his shirt to look at his midsection, pushing it out to make a fake baby bump. He sincerely wondered when exactly he was going to start showing. He hadn't asked his brother about the topic; he wanted the whole thing to be a secret until the time was right.

Soon, about a month had passed and things ended up confusing Izuna. He had felt fine for the entirety of the six weeks when he was supposed to experience the first few signs of pregnancy, the most prominent being morning sickness. Much to his surprise, he hadn't felt sick or queasy at all. He guessed it had something to do with Tobirama's jutsu.

Speaking of his husband, Izuna had not seen Tobirama much during the previous week. It seemed like Tobirama was avoiding him and that worried him. Was he mentally preparing himself that he would be a father sometime soon? Were things at the Hokage's office beginning to pile up? Was he concerned that the jutsu had failed and went back to work on it? Izuna had no idea.

He sighed, holding Ryo close to him as he watched Izumi and Akio draw on a blank sheet of paper. He smirked at the off kilter and disproportioned illustrations of their family. Izumi was sketching her parents holding the hands of the kids while a smiling sun was looking down on them. Akio…he had no idea what the blue and black blobs he was making were.

"Is that supposed to be Uncle Tobi and Uncle 'Zuzu?" Izumi asked Akio. The boy nodded happily. "Great! Be sure to add hair to them! You don't want them bald, do you?"

Akio fearfully looked at his picture before he frantically began adding hair to the figures. Izuna chuckled at his nephew. He then jerked at the sound of the front door slamming open. Placing Ryo down, he immediately jumped up and rushed to where he heard the noise. He let out a gasp. Tobirama was there, leaning against the wall with his arms wrapped tightly around his stomach. He looked pale and seemed to be in pain. If he were anyone else, he'd be ready to collapse to the floor right then and there.

"Tobirama, what happened?" Izuna worriedly asked.

Tobirama raised his head to look at Izuna. He opened his mouth, but all that came out was a gag. He immediately slammed a hand over his mouth before he hurried past Izuna, heading for the bathroom. Izuna followed after him, cringing when he heard his husband retching. He peeked into the bathroom to find Tobirama hunched over the porcelain throne, visibly shaking as he hurled into it. Izuna knelt down next to the Senju, rubbing his back as he continued to vomit. Once Tobirama was done, he placed his forehead against the cool material of the toilet before flushing his stomach contents away.

"Tobirama? Are you alright?"

"Crap…" was Tobirama's only reply.

And here we are! The sequel to Three Words! kitsunelover300 and I present Three Promises! This time, we'll be focusing on Tobirama and Izuna's budding family. It looks like Tobirama's "gift" ended up with the wrong person. =3

It's a bit of a short first chapter, but I'll make up for it in future ones. What will happen this time around with the "joys" of pregnancy? Be sure to fav, follow, and/or review! Stay tuned for the next chapter!
